    [0001] The present invention relates to a door interlock device applied to a vehicle, such as a four-wheeled automobile. More particularly, the present invention relates to a door locking apparatus which comprises a closing mechanism and a locking mechanism. The closing mechanism, when a door is in a closed position with respect to a main vehicle body, restricts movement of the door in an open direction by being closed. The locking mechanism is disposed between a door handle and the closing mechanism. When the door handle is actuated to be opened in an unlocked state, the locking mechanism cancels the closed state by transmitting such opening actuation of the door handle to the closing mechanism, and allows movement of the door in the opening direction. In a locked state, the locking mechanism maintains the closed state of the closing mechanism, even if the door handle is actuated to open. As is known in the art, to improve operational efficiency, door interlocking devices that switch a locked state / unlocked state of a locking mechanism through a lock actuator have been proposed. Some of the door interlock devices omit a lock actuation member to switch the locked / unlocked state from within the vehicle to enhance a vehicle anti-theft function. In other words, with the door interlock device whose locking actuation element inside the vehicle is omitted, even if a window is broken, it is difficult to switch the locking mechanism in the door. locked state in the unlocked state, thus improving the antitheft function of the vehicle. However, when the lock actuating element is omitted, when a failure occurs on a drive system and a power supply system of the lock actuator, for example, it is difficult to switch the lock actuator. locking mechanism in the locked state. As a result, a problem may occur such that the vehicle can not be left unattended. Thus, in the related art, an actuation button is provided in a locked position when the door is in a closed position, and the locking mechanism is put in the locked state by actuating the button. With the door interlock device, even if the fault occurs on the drive system and the power supply system of the locking actuator, the locking mechanism can be put in the locked state by actuating the button. Since the actuation button can only be operated when the door is opened, the anti-theft function of the vehicle is not affected. Some of the door lock devices include a so-called child lock mechanism. The child safety lock mechanism prevents a door (rear door) from opening, for example, even if a child sitting in a rear seat of the vehicle operates to open an interior door handle arranged inside the vehicle. More particularly, the child safety lock mechanism is disposed between the inner door handle and the locking mechanism, and switchably configured between a transmission state and a non-transmission state. The transmission state transmits the opening actuation of the interior door handle to the locking mechanism, and the non-transmission state does not transmit the opening actuation of the interior door handle to the locking mechanism. . Such a child safety locking mechanism, similar to the actuating button, is switched between the transmission state and the non-transmission state, by actuating a child safety lever arranged in a closed position when the door is in the closed position.
    [0002] However, in the door interlock device which includes such a child safety lock mechanism, switching between the transmission state / non-transmission state of the child safety lock mechanism is performed by manually operating the child lock lever. child safety. Because the child safety lever is arranged in the locked position when the door is in the closed position, when the vehicle starts to move without putting the child safety lock mechanism in the non-transmission state, the door can be opened while moving, by operating to open the interior door handle.
    [0003] Japanese Laid-open Patent Application No. 2005273173 discloses a door latch mechanism which includes a child safety lock actuator that switches the child safety lock mechanism between the transmission state and the state of the child. non-transmission. When a vehicle speed detected by a speed detection unit, for example, is equal to or greater than 5 kilometers per hour, the child safety lock mechanism is set to the non-transmission state by driving the vehicle. child safety lock actuator. When the vehicle speed detected by the speed detection unit is less than 5 kilometers per hour and when it is judged that the vehicle is stopped, the child safety lock mechanism is put into the transmission state by driving the child safety lock actuator. Some of the door lock devices applied to the vehicle include a so-called double lock function (super lock function). The double locking function, when in a state of operation, disables the opening operation of an outside door handle arranged outside a driver's side door and the interior door handle. Therefore, the double lock function can enhance the anti-theft function.
    [0004] However, in the door locking apparatus proposed in Japanese Patent Application Laid-open No. 2005-273173, when it is judged that the vehicle is stopped, the child safety lock mechanism is put into the transmission state by driving the child safety lock actuator. Therefore, when the inner door handle is operated to be opened by breaking the window, the door (rear door) is opened, thus not satisfying the anti-theft function. It is an object of the present invention to at least partially solve problems in conventional technology. According to one aspect of the present invention, a door locking apparatus comprises: a closing mechanism which limits, when a door is in a closed position with respect to a main vehicle body, the movement of the door in a direction d 'opening ; a locking mechanism which is arranged between a door handle and the closing mechanism, and which allows movement of the door in the opening direction by releasing such a closed state by transmitting such opening actuation of the door handle; door to the closing mechanism when the door handle is actuated to be opened in an unlocked state, and which maintains the closed condition of the closing mechanism even if the door handle is actuated to be opened during a locked state; a lock actuator that switches the lock mechanism between the locked state and the unlocked state; a child safety lock mechanism which is disposed between an interior door handle arranged inside a vehicle and the locking mechanism, and switches between a transmission state which transmits the opening actuation of the door handle; an internal door to the locking mechanism and a non-transmission state that does not transmit the opening actuation of the interior door handle to the locking mechanism; a child safety lock actuator that switches the child lock mechanism between the transmission state and the non-transmission state; and a control unit which controls the door lock apparatus. The control unit: switches the child safety lock mechanism to the non-transmission state by providing a command to the child safety lock actuator when a vehicle speed detected by a speed detection unit is equal to or greater than a predetermined threshold; switches the child safety lock mechanism to the transmission state by providing the command to the child safety lock actuator when the vehicle speed detected by the speed detection unit is below the threshold, and also at least when a speed position detecting unit detects a speed in a parking position or when a foot brake detection unit detects that no bearing action is performed on a foot brake; and switches the locking mechanism to the locked state by providing control to the lock actuator and switches the child safety lock mechanism to the non-transmission state by providing control to the safety lock actuator child when a double lock command is provided to disable opening actuations of an outboard exterior handle and the interior door handle.

Examples of embodiments of a door lock apparatus according to the present invention are now be explained in detail below with reference to the accompanying drawings. Figures 1 to 3 are conceptual drawings of a door interlock apparatus according to one embodiment of the present invention. As shown in Fig. 4, the door locking apparatus explained herein is provided in a door (rear door) D which has a front hinge disposed at a right rear seat of a vehicle main body B of a four-wheeled automobile. As shown in Fig. 1, the door lock apparatus includes a closure mechanism 20 in a closure housing 21 mounted on a main body housing 10. The closure mechanism 20, as shown in Figs. 4 and 5, meshes with and retains a lock striker S included in the main vehicle body B, and as shown in FIG. 5, comprises a latch 22 and a pawl 23.
    [0007] The latch 22 is rotatably arranged in a position above a lock strike introduction groove 21a formed in a closure housing 21 about a latch shaft 24 extending horizontally along a latch shaft 21a. longitudinal direction of the main body of vehicle B. The latch 22 comprises a meshing groove 22a, a hooking portion 22b, and an engaging portion 22c. The engagement groove 22a is formed toward the latch shaft 24 from an outer peripheral surface of the latch 22, and formed in a width which may contain the lock striker S. The latching portion 22b is a portion positioned more on the inner side than the meshing groove 22a, when the meshing groove 22a is open downwardly. The engaging portion 22b, as shown with a solid line in FIG. 5, stops in a position to cut through the lock strike introduction groove 21a of the closure housing 21, when the latch 22 is turned counterclockwise as much as possible.
    [0008] Further, as shown with the dotted two-dot line in Figure 5, the hooking portion 22b is formed to stop in a position to open the lock strike insertion groove 21a, when the latch 22 is rotated clockwise as far as possible. The engaging portion 22c is a portion positioned more on the outside of the vehicle than the meshing groove 22a, when the engagement groove 22a is open downwardly. The engagement portion 22c, as shown with the dotted line in Figure 5, is formed to stop in the state to cut through the lock strike introduction groove 21a, when the latch 22 is rotated clockwise as far as possible, and progressively inclined upward towards the rear side (outside the vehicle) of the lock strike insertion groove 21a. Although not shown, a latch spring which biases latch 22 continuously in a clockwise direction in FIG. 5 is provided between latch 22 and closure housing 21. Pawl 23 is rotatably arranged in a position below the lock strike insertion groove 21a of the closure housing 21 and more on the inside of the vehicle than the latch shaft 24, about a pawl shaft 25 which extends horizontally along the front-rear direction of the vehicle main body B. The pawl 23 includes an engaging portion 23a and an engaging portion 23b. The engaging portion 23a is a portion extending radially outwardly, outwardly of the vehicle from the pawl shaft 25. In addition, the engaging portion 23a may be releasably engaged with the engaging portion 22b and the engaging portion 22c of the latch 22, through the projecting facet by rotating about the ratchet shaft 25. The portion of 23b is a portion that extends radially outwardly to the vehicle interior from the pawl shaft 25. The pawl 23 includes a ratchet lever 26 which rotates integrally around the center of the ratchet shaft 25 with the pawl 23 on a front side of the vehicle.
    [0009] The ratchet lever 26 comprises a stop portion 26a which extends in the same direction as the action portion 23b of the ratchet 23 from the ratchet shaft 25. Although not shown, a ratchet spring which the pawl 23 continuously in the counterclockwise direction in Figure 5 is provided between the pawl 23 and the closure housing 21. The closing mechanism 20 formed as described above, as shown with the two-dot hyphen in Fig. 4, when a door D is in an open state with respect to the vehicle main body B, as shown with the dotted line in Fig. 5, the latch 22 is disposed in a position to open the lock strike insertion groove 21a. From this state, as shown with the solid line in Fig. 4, when the door D is moved to a closed position, the lock striker S provided on the main vehicle body B, as shown in Fig. 5, enters the lock keeper insertion groove 21a of the closure housing 21, and then the lock keeper S abutting against the engaging portion 22c of the latch 22. Accordingly, the latch 22 rotates counterclockwise in Figure 5 against the spring force of the latch spring (not shown). During this time, since the protruding facet of the engaging portion 23a slides on the outer peripheral surface of the latch 22, due to the resilient force of the pawl spring (not shown), the pawl 23 rotates appropriately. around the center of the ratchet shaft 25 corresponding to the shape of the outer peripheral surface of the latch 22. When the door D is moved further in the closed direction from the above-mentioned state, the entry amount the lock striker S with respect to the lock striker insertion groove 21a progressively increases, and then the engaging portion 23a of the pawl 23 reaches the engagement groove 22a of the latch 22. Then, as is shown with the solid line in FIG. 5, the latching portion 22b of the latch 22 is abutted against the engaging portion 23a of the pawl 23, thereby preventing rotation in the clockwise direction of a latch e shows the latch 22, against the elastic return force of the latch spring (not shown). In this state, the catch portion 22b of the latch 22 is disposed to cut through the lock strike introduction groove 21a, thereby preventing the lock strike S from moving toward a direction to detach from the back side. (outside the vehicle) lock lock introduction groove 21a due to the hooking portion 22b.
    [0010] As a result, the door D is kept in the closed state relative to the main vehicle body B (closed state). When the abutment portion 26a of the pawl lever 26 is set up in FIG. 5, against the elastic force of the pawl spring (not shown) from the closed state, the stopping / entering state engaged between the hooking portion 22b of the latch 22 and the engaging portion 23a of the pawl 23 is canceled, thereby rotating the latch 22 in a clockwise direction in FIG. resilient return force of the latch spring (not shown). Accordingly, as shown with the dotted two-dot line in FIG. 5, the lock strike introduction groove 21a is open, and the lock strike S can move in one direction to become out of engagement with the lock strike introduction groove 21a. Therefore, the door D can be opened and moved relative to the main body of vehicle B.
    [0011] The door lock apparatus, as shown in Fig. 1, includes an opening lever 11, an inner handle lever 12, and a locking mechanism 30 in the main body housing 10. The lever of opening 11, although not shown, is rotatably disposed about an opening lever shaft which extends horizontally along the forward-rearward direction of the vehicle main body B, and includes an end of actuation 11a and a pressure receiving portion 11b. The actuating end 11a of the opening lever 11 is disposed in a lower region of the abutment portion 26a in the pawl lever 26. The pressure receiving portion 11b of the opening lever 11 is a portion which curves upward after having spread below the actuating end 11a. The opening lever 11 rotates appropriately around a hinge, when an ODH outer door handle (see Fig. 4) provided on an outer surface of the door D is actuated to be opened, and moves the end of the door. 11a and the pressure receiving portion 11b upwardly in FIG. 1. Although not shown, an opening lever spring continuously urges the actuating end 11a and the receiving portion of the The inner door lever 12 is provided in a pivoted manner in a region further in front of the vehicle than is provided between the opening lever 11 and the main body housing 10. the opening lever 11, about an inner lever shaft 13 which extends horizontally along the left right direction of the vehicle main body B. The inner handle lever 12 comprises an end 12a and an inner handle locking link portion 12b. The actuating end 12a is a portion that extends downwardly from the inner lever shaft 13, and an IDH inner door handle (see Fig. 4) is appropriately connected via a joint at the end. The actuating end 12a, when the inner door handle IDH is actuated to be opened, is formed so that the inner handle lever 12 is rotated clockwise in FIG. Inner handle lock link 12b is a portion that extends rearwardly of the vehicle from inner lever shaft 13. Locking mechanism 30 is formed to switch between an unlocked state and a locked state . The unlocked state transmits the rotation of the opening lever 11 by the opening operation of the outer door handle ODH to the closing mechanism 20. The locked state does not transmit the rotation of the opening lever 11 by the OPENING OPERATION OF THE Outer Door Handle ODH TO THE CLOSING MECHANISM 20. The locking mechanism 30 comprises a worm wheel 31, a sector lever 32, and a hinge lever 33. The worm 31 is rotatably disposed in a region between the opening lever 11 and the inner handle lever 12 about a wheel shaft 34 which extends horizontally along the left-right direction of the wheel. the main vehicle body B. The worm wheel 31 is meshed with a worm 36 attached to an output shaft 35a of an electric motor (lock actuator) 35. An intermittent gear wheel 37 is attached coaxially around the same worm gear shaft center 31. The intermittent gear wheel 37 forms an intermittent power transmission portion only in one direction with respect to an intermittent drive gear 32b of the sector lever 32, which will be explained below. The sector lever 32 is rotatably arranged in a position above the worm wheel 31 around a sector lever shaft 38 which extends horizontally along the left direction - The sector lever 32 is formed in a sector shape which progressively expands and opens downwards. The sector lever 32 includes a connecting pin 32a and the intermittent driven gear 32b. The connecting pin 32a is a columnar protuberance extending horizontally along the left-right direction of the vehicle main body B, from a facet positioned inside the vehicle 10 in the sector lever. 32. The intermittent driven gear 32b is a gear formed on an outer peripheral surface of the mains lever 32 made in an arc, and meshing with the intermittent gear wheel 37 of the worm gear 31. Although not shown , the intermittent power transmission portion formed between the intermittent drive gear 32b of the mains lever 32 and the intermittent gear wheel 37 of the worm wheel 31 can pivot the sector lever 32 in any direction turning the worm wheel 31 in a proper direction. Since the power is not transmitted to the intermittent gear wheel 37 from the intermittent driven gear 32b, the intermittent power transmission portion is formed to pivot the sector lever 32 in any direction The hinge lever 33 is a lever member that includes an installation port 33b on a lower end of a hinge main body 33a. By inserting and maintaining the actuating end 11a of the opening lever 11 in the installation port 33b, the hinge lever 33 can be moved vertically with the actuating end 11a and the 11b, and pivotally supported by an axis along the left-right direction of the vehicle main body B with respect to the actuating end 11a. The hinge lever 33 includes a sector connection portion 33c and a ratchet drive portion 33d. The sector link portion 33c is a portion that extends upwardly from the front side region of the vehicle in the hinge main body 33a, and includes a link groove hole 33e. The connecting groove hole 33e is a slot opening that extends along the vertical direction, and movably installs and supports the connecting pin 32a of the sector lever 32 therein. The ratchet drive portion 33d is an abutment and engagement portion formed on the hinge main body 33a, and when disposed vertically above the installation port 33b, the pawl drive portion 33d is provided in a mode substantially opposite to the lower facet of the abutment portion 26a in the ratchet lever 26. The hinge lever 33 also includes a locking lever portion lock) 33f. The locking lever portion 33f is a portion that extends downward below the installation port 33b, when the hinge main body 33a is vertically disposed above the installation port 33b . The lock lever portion 33f includes an actuating and abutting surface 33g in the front side region of the vehicle.
    [0012] The actuating and abutting surface 33g is formed to extend vertically, when the hinge main body 33a is vertically disposed above the installation port 33b. In the locking mechanism 30 formed as described above, the state shown in Fig. 1 is the unlocked state, and the hinge main body 33a of the hinge lever 33 is disposed vertically above the installation port 33b. Therefore, the pawl driving portion 33d is closely opposed to the lower facet of the abutment portion 26a in the pawl lever 26. Thus, when the outer door handle ODH is actuated to be opened from it. state, and the hinge main body 33a of the hinge lever 33 is moved upwards by the operation of rotation of the opening lever 11, the ratchet driving portion 33d is abutted against the part of stop 26a of the ratchet lever 26 in the closure mechanism 20, thereby moving the abutment portion 26a upwards. Accordingly, even if the closing mechanism 20 is in the closed state, the closed state is canceled, thereby opening and moving the door D relative to the main body of the vehicle B. When the electric motor 35 driving and rotating the worm wheel 31 counterclockwise from the unlocked state shown in Fig. 1, the sector lever 32 pivots clockwise around of the sector lever shaft 38. Accordingly, the hinge lever 33 engaged through the connecting pin 32a pivots counterclockwise around the installation hole. 33b, thereby putting the locking mechanism 30 in the locked state, as shown in FIG. 3. In the locked state, the ratchet driving portion 33d deviates from the opposite position to the lower facet of the party of bu 26a in the ratchet lever 26. Therefore, even if the outer door handle ODH is actuated to be opened, and the hinge main body 33a of the hinge lever 33 moves upward due to the rotating operation of the opening lever 11, the ratchet driving portion 33d does not abut against the abutment portion 26a of the ratchet lever 26 in the closing mechanism 20. As a result, when the closing mechanism 20 is in the closed state, the closed state is maintained, thus keeping the door D in the closed position relative to the main vehicle body B. When the electric motor 35 drives and rotates the worm wheel 31 in clockwise from the locked state shown in Fig. 3, the sector lever 32 pivots counterclockwise around the sector lever shaft 38. Accordingly, , the hinge lever 33 engaged through the connecting pin 32a pivots clockwise around the installation port 33b, thereby returning the locking mechanism 30 back into the unlocked state shown in Figure 1.
    [0013] The door lock apparatus, as shown in FIG. 1, also includes a child lock mechanism 40 in the main body housing 10. The child lock mechanism 40 is configured to switch between a transmission state and a non-transmission state. The transmission state transmits the opening action of the IDH interior door handle to the locking mechanism 30, and the non-transmission state does not transmit the opening actuation of the interior door handle IDH to locking mechanism 30. The child safety lock mechanism 40 comprises a link lever 41 and a child safety lever 42. The link lever 41 is pivotally arranged in a region between the inner handle lever 12 and the lever articulation member 33, about a link lever shaft 43 which extends horizontally along the left-right direction of the vehicle main body B. The link lever 41 comprises a transmission pin housing portion 41a and a transmission end 41b. The transmission pin housing portion 41a is a portion that extends forwardly of the vehicle from the link lever shaft 43, and includes a pin housing 41c. The pin accommodating port 41c is a slot opening formed along the direction in which the transmission pin housing portion 41a extends. As is apparent from Fig. 1, the pin-receiving hole 41c formed in the transmission pin-housing portion 41a is configured so that the end on the front side of the vehicle with respect to a range of pivoting is included therein, and the end on the rear side of the vehicle deviates from the pivoting range, when the inner handle lock link portion 12b of the inner handle lever 12 pivots about the shaft The transmission end 41b is a tilting portion and extends slightly downwardly toward the rear of the vehicle from the link lever shaft 43. The extending end of the transmission end 41b is disposed in the lower region of the pressure receiving portion 11b in the opening lever 11. The child safety lever 42 is slidably arranged along the forward direction - rear of the main body of vehicle B, between the link lever 41 and the main body housing 10 in a mode of overlap with the link lever 41. The child safety lever 42 comprises a sliding groove 42a, a groove of transmission pin carrier 42b, a notch engagement portion 42c, a manual actuation portion 42d, and a lock actuation portion 42e. The slide groove 42a is a slot opening for inserting the connecting lever shaft 43 of the link lever 41, and extending along the front-rear direction of the vehicle main body B. The length of the groove sliding 42a determines a sliding amount of the child safety lever 42, and is adjusted to perform the action that will be explained below. The transmission pin holder groove 42b is a slot opening and supports a sliding pin 44 slidably. The transmission pin 44 is a columnar element protruding outwardly of the vehicle from the child safety lever 42. The transmission pin 44, as shown in FIG. 6, after having penetrated through the orifice pin housing 41c of the link lever 41, reaches a position in which the protruding end projects beyond the outer facet of the inner handle lever 12. The transmission pin 44 allows the child safety lever 42 to slide, as shown in Figures 1 and 3, thereby moving between the end on the front side of the vehicle to the end on the rear side of the vehicle of the pin housing 41c formed on the connecting lever 41 The notch engaging portion 42c is a concave groove which engages a notch 14 provided on the inner surface of the main body housing 10, and three portions The notch engagement sockets 42c are provided on the upper edge of the child safety lever 42. The notch engaging portion 42c at the rear of the vehicle, as shown in FIGS. 7, defines the front end position of the child safety lever 42 relative to the main body housing 10 when the notch 14 is engaged. Similarly, the notch engaging portion 42c at the front of the vehicle, as shown in FIGS. 3 and 7, defines the rear end position of the child safety lever 42 relative to the housing. main body 10, when the notch 14 is engaged. The notch engagement portion 42c in the middle, as shown in FIGS. 2 and 7, defines the middle position of the child safety lever 42 relative to the main body housing 10, when the notch 14 is in take. When the child safety lever 42 is disposed in the front end position, as shown in FIG. 1, the transmission pin 44 is disposed in a pivoting range of the inner handle locking link portion 12b in the inner handle lever 12. When the child safety lever 42 is disposed in the middle position or the rear end position, as shown in Figures 2 and 3, the transmission pin 44 is disposed outside the pivoting range of the inner handle locking link portion 12b in both cases.
    [0014] The manual actuating portion 42d, as shown in FIG. 6, is a portion that curves and extends inward from the end on the rear side of the vehicle into the child safety lever 42. The manual actuating portion 42d protrudes externally through an actuating port 10a provided at the main body housing 10 and a DPO actuating opening provided at a door DP panel. D. The manual actuating portion 42d can slide the child safety lever 42 from the outside of the door D. However, in the present embodiment, as shown in FIG. Manual actuation 42d is provided on the inner surface of the door D, and in a locked position when the door D is in the closed position. As shown in FIG. 7, at the DPO actuation opening of the DP panel whose manual actuating part 42d is exposed to the outside, the display corresponding to each actuating position is provided on this one.
    [0015] The lock actuating portion 42e, as shown in Fig. 6, is curved and extended outwardly from the end on the rear side of the vehicle into the child safety lever 42, and is a part of opposite to the actuating and abutting surface 33g of the locking lever portion 33f in the locking mechanism 30. The locking actuating portion 42e, as shown in Figures 1 and 2, when the child safety lever 42 is disposed in the front end position and the middle position, is disposed in a position separate from the actuating and abutment surface 33g of the vertically extending locking lever portion 33f down from the installation port 33b. The lock actuating portion 42e, as shown in Fig. 3, when the child safety lever 42 is disposed in the rear end position, rotates the hinge lever 33 counterclockwise. a watch via the actuating and abutting surface 33g, and is provided in a position where the locking mechanism 30 can be switched to the locked state. The child safety lever 42, as shown in FIG. 1, is connected to a child safety lock actuator 45. The child safety lock actuator 45 drives the child safety lever 42 in order to move sliding between the front end position and the rear end position. With the child safety lock mechanism 40, the state shown in FIG. 1 is the transmission state, and the transmission pin 44 of the child safety lever 42 is disposed in the pivoting range of the connecting portion of FIG. 12b interior handle lock in the inner handle lever 12. When the inner door handle IDH is actuated to be opened from this state, the inner handle lock connecting portion 12b moves the transmission pin 44 downwardly. . When the transmission pin 44 moves down along the transmission pin holder groove 42b, the link lever 41 having penetrated with the transmission pin 44 pivots counterclockwise on the Figure 1, and the transmission end 41b moves upwards. Therefore, the hinge lever 33 moves upwardly through the pressure-receiving portion 11b of the opening lever 11. Thus, when the locking mechanism 30 is in the unlocked state, the hinge lever 33 abuts against the abutment portion 26a of the pawl lever 26 in the closure mechanism 20, thereby canceling the closed state. In other words, the door D can be opened and moved by the opening operation of the interior door handle IDH. On the other hand, when the child safety lever 42 slides towards the rear side of the vehicle, and is switched to the state shown in Figure 2, or the state shown in Figure 3, the child safety lock mechanism 40 is put in the non-transmission state. In the non-transmission state, the transmission pin 44 of the child safety lever 42 is disposed outside the pivoting range of the inner handle locking link portion 12b in the inner handle lever 12. therefore, even if the IDH interior door handle is actuated to be opened, the inner handle locking link portion 12b and the transmission pin 44 will not abut, thereby not pivoting the link lever 41. Accordingly, regardless of the locked / unlocked state of the locking mechanism 30, the door D can not be opened or moved by the opening operation of the interior door handle IDH. Fig. 8 is a block diagram of a control system of the door locking apparatus according to the embodiment of the present invention. The door interlock apparatus of the present embodiment comprises a vehicle speed detection sensor S1, a speed position detection sensor S2, a foot brake detection sensor S3, a double lock control switch. SW, and a control portion 50. The vehicle speed detection sensor S1 is a speed detection unit that detects the vehicle speed, in other words, the speed of the vehicle on which the vehicle lock device door is applied, and provides a detected signal to the control unit 50 as a vehicle speed detection signal. The speed position detection sensor S2 is a speed position detecting unit which detects a speed position of the vehicle in a parking position, and provides a detected signal to the control unit 50 as a detection signal. parking position. The S3 foot brake detection sensor is a foot brake detection unit that detects that a vehicle foot brake is in a non-operating state, in other words, that the foot brake does not take place. no pressing action thereon, and provides a detected signal to the control unit 50 as a foot brake detection signal. The double lock control switch SW, for example, is embedded in a key body that belongs to a user, and provides a double lock command to the control unit 50, when the user presses a predetermined button . The double lock control switch SW can not only be recessed in the key main body, but the double lock control can be provided to the control unit 50, when the user closes a driver's side door (front door). , and performs a lock operation by inserting a key in a key cylinder of the door. The control unit 50 operates on the basis of a computer program and data stored in a memory 60, and includes an input processing unit 51, a driving judgment unit 52, a unit latch actuator drive processing 53, and a child safety lock actuator drive processing unit 54. The input processing unit 51 inputs and processes the signal and command provided by the respective detection sensors S1 to S3 and the double lock control switch SW. The driving state judgment unit 52 judges a driving state of the vehicle. More particularly, the driving state judgment unit 52, when the vehicle speed of the vehicle speed detection signal processed by the input processing unit 51 is equal to or greater than a vehicle speed. predetermined reference (threshold: such as 3 kilometers per hour), judge that the vehicle is in a state of driving. When the vehicle speed is lower than the reference vehicle speed, and when the speed is in the parking position and the foot brake is not depressed thereon, as a result of the signal processing in the input processing section 51, the driving state judgment part 52 judges that the vehicle is in a stopped state. The lock actuator drive processing unit 53 controls the electric motor 35. The child lock safety actuator drive processing unit 54 controls the child safety lock actuator 45. the door interlock device which includes the locking mechanism 30 and the child safety lock mechanism 40, when the electric motor 35 is driven in normal use, the locking mechanism 30 can easily be switched between the state locked and the unlocked state. When a fault occurs on the electric motor 35 or when the electric motor 35 does not work, for example, because the charged voltage of a battery, which is not shown, is low, the lever of child safety device 42 can slide and be moved to the rear side of the vehicle through the manual actuating portion 42d while the door D is open, and disposed in a position of "emergency operation" ("emergency ON ") shown in FIG. 7. In other words, when the child safety lever 42 is placed in the" emergency operation "position, the hinge lever 33 pivots through the part of 42e locking operation of the child safety lever 42, and the locking mechanism 30 can be switched to the locked state, as shown in Figure 3. So, even if the above-mentioned state occurs when the locking actuation element inside the vehicle is omitted, the anti-theft function of the vehicle can be obtained. In such a case, the child safety lever 42 is provided in the locked position when the door D is closed. Thus, even if a person intending to harm breaks a window, it is difficult to actuate the child safety lever 42. When the child safety lever 42 is placed in the "emergency operation" position, the child safety lock mechanism 40 is put in the non-transmission state. Thus, even if the child safety lever 42 is applied in the position that switches the locking mechanism 30 from the locked state to the unlocked state, by the operation of the interior door handle IDH, to improve when the locking mechanism 30 is in the locked state due to the actuation of the child safety lever 42, the locking mechanism 30 does not switch to the unlocked state, due to the actuation of the locking mechanism 30. opening of the IDH interior door handle. In this way, even with the door lock device with improved operational efficiency by applying a single-movement mechanism and a dual-action mechanism, the anti-theft function of the vehicle can be significantly improved. When the electric motor 35 can be driven again by changing the battery, the child safety lever 42 can be returned to the middle position through the actuating and abutting surface 33g of the lever portion of the locking 33f, by switching the locking mechanism 30 to the unlocked state.
    [0016] In the embodiment mentioned above, the notch 14 and the notch engaging portion 42c are provided between the child safety lever 42 and the main body housing 10. Therefore, a sense of moderation can be provided when the child safety lever 42 is actuated, thereby preventing an operational error. However, the present invention need not necessarily include the notch 14 and the notch engaging portion 42c between the child safety lever 42 and the main body housing 10. Even though the notch 14 and the notch engaging portion 42c is included, the notch 14 and the notch engaging portion 42c do not necessarily need to be individually provided. Figs. 9 to 11 are flowcharts for processing the contents of a drive detection command, a stop detection command, and a double lock command performed by the control units, respectively. Operation of the door lock apparatus is further explained by using Figures 9-11 as appropriate. The processing content of the control unit 50 in the drive detection control will now be explained. The explanation is made in the condition in which the vehicle is in the stopped state, the locking mechanism 30 is in the unlocked state, and the child safety lock mechanism 40 is in the transmission state. The vehicle starts driving in such a state. The control unit 50 in the drive detection control, when the vehicle speed detection signal provided by the vehicle speed detection sensor S1 is inputted and processed through the processing unit of the vehicle. 51 (Yes in S101), judges whether the detected vehicle speed included in the vehicle speed detection signal entered and processed through the input processing unit 51, by the intermediate of the driving state judgment unit 52, is equal to or greater than a predetermined reference vehicle speed (step S102). When the detected vehicle speed is lower than the reference vehicle speed (No in step S102), this command will be ended by returning to the procedure, without executing the method described below.
    [0017] When the detected vehicle speed is equal to or greater than the reference vehicle speed (Yes in step S102), the control unit 50 judges that the vehicle is in the driving state via the vehicle. The driving state judgment unit 52. The control unit 50 executes an electric motor driving process which switches the locking mechanism 30 to the locked state, driving the electric motor 35 through the lock actuator drive processing unit 53. The control unit 50 also executes a child safety lock actuator drive method that switches the child lock mechanism 40 to the state. of non-transmission, by driving the child safety lock actuator 45 through the child lock safety actuator drive processing unit 54 (step S103 and step S104). Then, the control unit 50 returns to the procedure, thus ending this command.
    [0018] Therefore, when the vehicle speed is equal to or greater than the reference vehicle speed (as equal to or greater than 3 kilometers per hour), the lock mechanism 30 in the unlocked state can easily be switched to the locked state. The child lock mechanism 40 in the transmission state can also be switched to the no-fault state of transmission. The processing content of the control unit 50 in the stop detection command will now be explained. The explanation is made in the condition in which the vehicle is in the driving state, the locking mechanism 30 is in the locked state and the child safety lock mechanism 40 is in the non-transmission state. The vehicle starts to stop in such a state. The control unit 50 in the stop detection control, when the vehicle speed detection signal supplied by the vehicle speed detection sensor S1 is input and processed through the processing unit of the vehicle. 51 (Yes in S201), judges whether the detected vehicle speed included in the vehicle speed detection signal, entered and processed through the input processing unit 51, is equal at or above a predetermined reference vehicle speed (step S202). When the detected vehicle speed is equal to or greater than the reference vehicle speed (Yes in step S202), the control unit 50 judges that the vehicle is not in the stopped state, thereby ending this command by returning to the procedure, without performing the method described below.
    [0019] When the detected vehicle speed is lower than the reference vehicle speed (No in step S202), the control unit 50, when the parking position detection signal is inputted by the parking position detection sensor. S2 speed, and the foot brake detection signal is input by the foot brake detection sensor S3, through the input processing unit 51 (Yes in step S203 and step S204) , judges that the vehicle is in the stopped state via the driving state judgment unit 52. Therefore, the control unit 50 executes the safety lock actuator drive method. a child who switches the child safety lock mechanism 40 by driving the child safety lock actuator 45, through the child lock safety actuator drive processing unit 54 (step S205), and finish this command by returning to the procedure after that. When the parking position detection signal is not inputted (No in step S203), or when the footbrake detection signal is not inputted (No in step S204), this command will be terminated by returning to the procedure, without executing the method in step S205. By judging that the vehicle is in the stopped state, not only when the vehicle speed is lower than the reference vehicle speed, but also when the speed position is detected in the parking position, and it is detected that the foot brake does not bear any action on it, the risk of switching the child safety lock mechanism 40, when the vehicle is simply stopped, for example, at a red light, can be prevented. Therefore, the state of the child lock mechanism 40 is not switched unnecessarily. Since the judgment is made on the basis of the vehicle speed, and the states of the speed position and the foot brake, it is possible to judge that the vehicle is in the stopped state without fault.
    [0020] The processing content of the control unit 50 in the double lock control will now be explained. The explanation is made in the condition in which the vehicle is in the stopped state, the locking mechanism 30 is in the unlocked state, and the child safety lock mechanism 40 is in the transmission state. The control unit 50 in the double lock control, when the double lock control provided by the double lock control switch SW is input and processed through the input processing unit 51 (Yes step S301), executes the electric motor driving process which switches the locking mechanism 30 to the locked state, driving the electric motor 35 through the actuator drive processing unit. The control unit 50 also executes the child safety lock actuator drive method that switches the child lock mechanism 40 to the non-transmission state, driving the child lock 45 through the child lock safety actuator drive processing unit 54 (step S302 and step S303). Then, the control unit 50 ends this command by returning to the procedure after that.
    [0021] The respective opening operations of the outer door handle ODH and the inner door handle IDH can be disabled by switching the locking mechanism 30 to the locked state and the child safety locking mechanism 40 to the state of non-transmission. In the door lock apparatus according to the embodiment of the present invention as explained above, the control unit 50 places the child safety lock mechanism 40 in the non-transmission state. when the vehicle speed detected by the vehicle speed detection sensor S1 is equal to or greater than the reference vehicle speed. When the vehicle speed detection sensor S1 detects that the vehicle speed is lower than the reference vehicle speed, when the speed position detection sensor S2 detects the speed is in the parking position, and the speed sensor is detected. S3 foot brake detection detects the foot brake does not bear pressure on it, the control unit 50 puts the child safety lock mechanism 40 in the transmission state. When the double lock command is provided, the control unit 50 sets the lock mechanism 30 into the locked state, and the child lock mechanism 40 into the non-transmission state. Therefore, the child safety lock mechanism 40 can be put into the faultless non-transmission state while the vehicle is being driven. When double lock control is provided, the respective opening operations of the ODH outer door handle and the IDH inner door handle can also be disabled, thereby improving the anti-theft function. Thus, the child safety lock mechanism 40 can be put into the faultless non-transmission state when the vehicle is driven, while satisfying the anti-theft function. The exemplary embodiments of the present invention have been explained, but the present invention is not limited to these embodiments, and various modifications may be made. For example, in the embodiment, the vehicle is judged to be in the stopped state when the vehicle speed is lower than the reference vehicle speed, the speed is in the parking position, and the foot brake is undergoes no action of support on this one. However, the present invention is not limited to this, and the vehicle can be judged to be in the stopped state when the vehicle speed is lower than the reference vehicle speed, and when the speed is detected as being in the parking position via the entered and processed parking position detection signal, or when it is detected that the foot brake is not depressed on it by the detection signal foot brake entered and treated. This system also puts the child safety lock mechanism 40 into the faultless non-transmission state while the vehicle is being driven, satisfying the anti-theft function. Particularly, when a driver stops the vehicle in a predetermined area, the current practice is to put the speed in the parking position or in the state of support on the foot brake. Even in such a case, the convenience can be improved by putting the child lock mechanism 40 into the transmission state.
    [0022] According to the present invention, the child safety lock mechanism can be put into the faultless non-transmission state while the vehicle is driven. In addition, when the double lock control is provided, the opening operation of the outside door handle is disabled, putting the locking mechanism in the locked state, and the opening operation of the door handle. Inner door is disabled by putting the child safety lock mechanism in the non-transmission state, thereby enhancing the anti-theft function. Therefore, the anti-theft function can be satisfied, while putting the child safety lock mechanism in the no-fault state while the vehicle is driven. Although the invention has been described with respect to specific embodiments for a complete and clear description, the appended claims should not be so limited but should be construed as making all the modifications and alternative constructions to which the man of the can think of and are rightly within the basic education presented herein.
