    Description
    Title of the invention: VEHICLE LIGHT AND LIGHTING CONTROL METHOD THEREOF Technical Field [0001] The present invention relates to a vehicle light that performs lighting of the light-scanning type and a control method lighting of it. PRIOR ART In order to improve a safety displacement performance of a vehicle such as an automobile, a technique has been proposed for detecting an object such as a preceding vehicle, an approaching vehicle, or a pedestrian in front of the car and to control the distribution of light so as not to dazzle a detected object. For example, an adaptive driving beam light distribution control of an automobile is a light distribution control that selectively does not illuminate an existing object in an area other than a lighting area d '' a dipped beam light distribution, in particular, an area above a cutoff line of the dipped beam light distribution. In order to carry out the adaptive driving beam light distribution control, a light of the light-scanning type is adopted.
    As a light which performs lighting of the light-scanning type (hereinafter called light-scanning light), a light has been proposed using a scanning mirror which provides lighting while changing a lighting direction of the light emitted by a light source. For example, in patent document 1, a rotating mirror (rotating reflector) which reflects light from a light source is rotated by a motor, so that a reflection angle of the rotating mirror is changed , and the lighting direction is changed.
    DOCUMENT OF THE PRIOR ART [0004] Patent document 1: W02016 / 104319
    SUMMARY In patent document 1, in order to have a lighting of a desired area in the control of distribution of light with an adaptive driving beam, it is necessary to allow the emission of light from the source of light and a time delay for rotating the rotating mirror, but a predetermined rise time is required until a speed of rotation of the motor driving the rotating mirror is stabilized. Consequently, during a first climb time during which the light beam is on, a flashing of the lighting occurs with a change in the speed of the engine, which causes a driver to feel an anomaly and a discomfort.
    With regard to such a problem, in the previous application (JP-A-2017-199342) previously filed by the present applicant, a technique has been proposed for continuing the rotation of the rotating mirror until a predetermined time elapses when a first unit of fire (light-streaking light) is extinguished. Therefore, when the first light unit is turned off, the rotating mirror is kept at a predetermined rotational speed as long as the first light unit is lit again within the predetermined time, and it is thus possible to avoid sensations abnormality and discomfort as described above.
    The prior application also proposed a technique for rotating the rotating mirror of the first light unit when the second light unit which is not a scanning type light illuminates. However, in this earlier application, with respect to the timing at which the rotation of the rotating mirror is started, a case of a lighting instruction in the first light unit and a case of a lighting instruction in the second fire unit are mixed. Therefore, when an ignition is made in which the rotating mirror is rotated based on the lighting instruction of the first light unit, there are cases where the sensations of abnormality and discomfort occur. occur before the rotational speed of the rotating engine stabilizes and which cannot always be resolved, and further improvement is required.
    An object of the present invention is to provide a vehicle light and a lighting control method thereof in which the sensations of anomaly and discomfort when a light streak light is lit are avoided .
    According to the present invention, a vehicle light is provided comprising:
    a first light configured to illuminate a required area when it is lit; a second light configured to light an area different from the required area when it is on; and lighting control means configured to control the lighting of the first light and the second light, wherein the second light comprises a light source and scanning means configured to scan the light emitted by the light source, and the lighting control means control the scanning means of the second light when the first light is on.
    According to the present invention, there is provided a lighting control method for a vehicle light, the vehicle light comprising:
    a first light configured to illuminate a required area when it is lit; and a second light configured to light an area different from the required area when it is turned on, and comprising a light source and scanning means configured to scan the light emitted by the light source, the method comprising the fact of:
    controlling the means for scanning the second light when the first light is on. In the vehicle light and the lighting control method thereof according to the present invention, for example, the first light is configured as a low beam unit which provides lighting with a light distribution of low beam, and the second light is configured as a high beam unit which illuminates an area different from an illuminated area with the distribution of low beam light. In addition, the scanning means comprise a motor and a rotating mirror which is rotated by the motor and changes the angle of reflection of the light coming from the light source when a position of rotation of the latter changes, and control the engine when the first light is on.
    According to the present invention, since the scanning means of the second light are controlled when the first light is lit, the scanning means are placed in a state of instantaneous realization of a predetermined scanning when the second light is lit. Therefore, even when the second fire is instantly lit, lighting can be achieved without the feeling of abnormality and discomfort.

    DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will then be described with reference to the drawings. Figure 1 is a schematic horizontal sectional view of an HL headlight of an automobile to which the present invention is applied. The HL headlight comprises a light housing 1 configured by a light body 11 and a translucent cover 12, and a low beam unit 2 and a high beam unit 3 mounted in the light housing 1. In the description which follows, a front-rear direction is a direction based on front-rear directions of the automobile and a light.
    The low beam unit 2 is a first light in the present invention, and is configured as a projector type light unit, and includes a first white light emitting diode 21 used as a light source configured to emit white light, a reflector 22 configured to reflect white light emitted by the first white light emitting diode 21 in a light collecting state, and a projection lens 23 configured to project white light collected by the reflector to an area 22.
    As shown in a light distribution characteristic diagram of Figure 2A, the low beam unit 2 has a cut-off line COL extending substantially along a horizontal line H of the area front of the automobile, and provides a low beam light distribution lighting which illuminates an area (upper left dotted area) PL under the cut-off line COL. The cut-off line COL has different heights between a right side (approaching track side) and a left side (side of its own track) of a vertical line V.
    The main beam unit 3 is a second lamp in the present invention, and is configured as a light scanning type unit with an adaptive driving beam light distribution control. The high beam unit 3 comprises a second white light emitting diode 31 configured to emit white light, scanning means 32 configured to reflect the white light emitted by the second white light emitting diode 31, and deflect a direction of reflection in a horizontal direction, and a projection lens 33 configured to project the white light reflected towards the front area of the automobile, and these are fixed on a radiator 30.
    The scanning means 32 comprise a brushless motor (hereinafter called a motor) 34 and a rotating mirror 35 fixed on a motor rotation shaft 34. The rotating mirror 35 is rotated by the motor 34, and is configured such that an angle in the horizontal direction of a reflecting surface facing the second white light emitting diode 31 changes continuously when a rotational position thereof changes. In addition, a hall effect element 36 is arranged in the motor 34, and a required detection signal is delivered according to the rotation drive of the motor 34.
    In the high beam unit 3, white light (white beam) L from the second white light emitting diode 31 is repeatedly scanned in the horizontal direction by the rotation of the rotating mirror 35, and like this is represented in FIG. 2B, by means of the scanning, is projected onto an area of distribution of high beam light with adaptive driving beam PH in an area (upper right dotted area) above the cut-off line COL of the PL high beam light distribution area for lighting. As will be described later, when a light emission delay of the second white light emitting diode 31 is controlled by an adaptive driving beam high beam light distribution control, the lighting to a part of the area Adaptive driving beam high beam light distribution lamp PH is off, and the adaptive driving beam high beam light distribution control is performed.
    An object detection device 4 is mounted in the light housing 1. The object detection device 4 comprises an image capture element 41 which captures an image of the front area of the automobile, and an image analysis part 42 which analyzes the image captured by the image capture element 41 to detect an object. When there is an object in the front area of the automobile, the object is picked up by the image capturing element 41 and detected by the image analysis part 42. Therefore, information position or equivalent comprising a position and a direction of the object relative to the automobile is detected.
    In addition, a lighting control device 5 is mounted in the light housing 1, and is connected to the first white light-emitting diode 21 of the dipped beam unit 2, the second white light-emitting diode 31 of the high beam unit 3, and the motor 34 and the hall effect element 36 of the high beam unit 3. In addition, the lighting control device 5 is also connected to the image analysis 42 in the object detection device 4.
    Figure 3 is a block diagram of the lighting control device 5. The lighting control device 5 comprises a first part of the lighting circuit 51, a second part of the lighting circuit 52, a motor control circuit part 53, and a rotating mirror detection part 54. The first lighting circuit part 51 controls a light emission from the first white light-emitting diode 21 of the low beam unit 2. The second part of the lighting circuit 52 controls a light emission from the second white light-emitting diode 31 of the high beam unit 3. The motor control circuit part 53 controls the rotation of the motor 34 which drives the mirror rotating 35 of the high beam unit 3. The rotating mirror detecting portion 54 detects a state of rotation of the motor 34, i.e. a state of rotation of the rotating mirror 35, based on the hall effect element 36 detection signal provided in the motor 34.
    Among these parts, the motor control circuit part 53 and the rotating mirror detection part 54 are not necessarily configured in one piece with the lighting control device 5, and can be configured independently. one from the other. In particular, the motor control circuit part 53 can be arranged close to the motor 34, or can be configured integrally with the motor 34.
    On the other hand, a lighting switch SW actuated by an occupant is connected to the lighting control device 5. By actuating the lighting switch SW, it is possible to establish two lighting modes, that is to say "dipped beam" which is a mode of lighting in a distribution of dipped beam and "high beam with adaptive driving beam" which is a mode of lighting in a distribution of dipped beam adaptive driving beam route.
    In other words, when the light switch SW is placed on "low beam", the first part of the lighting circuit 51 controls the emission of light from the first white light-emitting diode 21 of the low beam unit 2, and the low beam unit 2 is controlled to be turned on / off. Therefore, lighting with the low beam light distribution of Figure 2A is achieved. In addition, in the present invention, the rotation of the motor 34 is controlled by the motor control circuit portion 53 at the same time, and the rotation of the rotating mirror 35 is also controlled.
    When the light switch SW is placed on "high beam adaptive driving beam", in addition to the lighting "low beam" described above, the second part of the lighting circuit 52 controls furthermore the emission of light from the second white light-emitting diode 31 of the high beam unit 3. In the second part of the lighting circuit 52, the lighting with the distribution of high beam light shown in Figure 2B is produced. In addition, lighting with an adaptive driving beam light distribution is provided to control the light emission timing and a light intensity of the second white light-emitting diode 31 of the high beam unit 3, based on the state of rotation of the rotating mirror 35 detected by the rotating mirror detection part 54, the position information of the object detected by the object detection device 42, or equivalent.
    In the headlight of the embodiment, the "low beam" can be controlled independently, but the "high beam adaptive driving beam" can be controlled only when the control of the "low beam" is performed . That is, when the lighting with the distribution of low beam light with respect to the area PL in Figure 2A is realized, the lighting with the distribution of high beam light with respect to the PH zone in FIG. 2B can be produced in addition to this.
    The outline of the lighting control of the "low beam" and of the "main beam with an adaptive driving beam" in the HL headlight having the above configuration will be described with reference to a flowchart of the Figure 4. The lighting control device 5 determines a state of the light switch SW (SI), and when it is not on "OFF", that is to say when the "low beam" or the "adaptive driving beam main beam" is established, the first part of the lighting circuit 51 controls the first white light-emitting diode 21 to emit light (S2), and at the same time, the motor 34 is driven in rotation by the motor control circuit part 53 (S3). Therefore, the low beam unit 2 is turned on, and at the same time, only the rotating mirror 35 of the high beam unit 3 is driven.
    Then, the lighting control device 5 determines the state of the light switch SW (S4), and when the "high beam adaptive driving beam" is established, it is determined whether a speed of rotation of the rotating mirror 35 is equal to or greater than or not at a predetermined speed based on the detection of the rotating mirror detecting portion 54 (S5). When the speed of rotation of the rotating mirror 35 is equal to or greater than the predetermined speed, the second part of the lighting circuit 52 controls the second white light-emitting diode 31 to emit light (S6). Therefore, the high beam unit 3 is turned on, and the lighting in which the light of the second white light emitting diode 31 is scanned with the rotating mirror 35 is realized.
    Then, the state of the light switch SW is determined (S7), a process is returned when the state is "low beam", the process is returned to a step S5 when one is in "fire adaptive driving beam route ", and the first white light-emitting diode 21 and the second white light-emitting diode 31 are off, and the rotation of the rotating mirror 35 is stopped when it is" OFF ". As a result, the HL headlight is turned off.
    Figure 5 is a timing diagram showing an example of the lighting control. The timing diagram shows, from the top, a lighting state of the low beam unit 2, the rotating state of the rotating mirror 35, and a lighting state of the high beam unit 3. Vertical axes of the two light units 2, 3 indicate the light intensities of the respective white light-emitting diodes, and a vertical axis of the rotating mirror 35 indicates the speed of rotation thereof.
    [0039] "Low beam" control
    In FIG. 5, when the occupant (driver) places the lighting switch SW on “low beam” at time t1, the first part of the lighting circuit 51 of the lighting control device 5 controls the first white light emitting diode 21 for emitting light. Therefore, the low beam unit 2 is turned on, and lighting with the low beam light distribution shown in Figure 2A is achieved. At this time, the engine control circuit portion 53 of the lighting control device 5 controls the rotation of the engine 34. Therefore, in the high beam unit 3, the rotating mirror 35 is driven in rotation, but the second white light-emitting diode 31 does not emit light, and lighting by the high beam unit 3 is not achieved.
    When the light switch SW is open from "low beam" at time t2, the light emission of the first white light-emitting diode 21 is stopped by the control of the first part of circuit d lighting 51, and the low beam unit 2 is off. At the same time, the engine control circuit 53 of the lighting control device 5 stops the rotation of the engine 34, and the rotation of the rotating mirror 35 of the high beam unit 3 is also stopped.
    "High beam adaptive driving beam"
    In Figure 5, when the occupant (driver) places the light switch
    SW on "adaptive driving beam main beam" at time t3, the first part of the lighting circuit 51 of the lighting control device 5 controls the first white light-emitting diode 21 to emit the light. Therefore, the dipped beam unit 2 is turned on, and lighting with the dipped beam light distribution shown in Figure 2A is achieved. At the same time, the engine control circuit portion 53 of the lighting control device 5 controls the rotation of the engine 34.
    Next, the second part of the lighting circuit 52 refers to the speed of rotation of the rotating mirror 35 detected by the rotating mirror detection part 54, and brings the second white light-emitting diode 31 of the light unit of route 3 to emit light at an instant t3a when the speed of rotation of the latter reaches the predetermined speed. Therefore, the high beam unit 3 scans the white light from the second white light emitting diode 31, and performs the lighting with the adaptive driving beam high beam light distribution of Figure 2B.
    In this case, since a required rise time Ts is generated from the setting of the lighting switch SW until the rotating mirror 35 reaches the predetermined rotation speed, the lighting with the light distribution of the main beam with adaptive driving beam is delayed by the rise time Ts. However, while waiting for the rise time Ts, the lighting in a state where the speed of rotation of the rotating mirror 35 has not reached the predetermined speed is prevented in advance during an initial period of lighting start-up. the high beam unit 3, thereby preventing sensations of abnormality and discomfort.
    In "high beam adaptive driving beam", the object detection device 4 captures the image of the front area of the automobile with the image capture element 41, and detects a object from the image captured by the image analysis part 42. In an example shown in FIG. 6, pedestrians Ml, M2 and an approaching vehicle CAR are detected. When these objects are detected, the second part of the lighting circuit 52 of the lighting control device 5 controls the light emission delay and a light intensity of the second white light-emitting diode 31 (including the absence emitting light) based on the position (direction) of the object detected by the object detection device 4 and the rotational position of the rotating mirror 35 detected by the rotating mirror detecting part 54.
    As shown in Figure 6, with regard to the high beam light distribution area with adaptive driving beam PH, areas where the objects Ml, M2, and CAR exist are not irradiated with the light beam L of the white light-emitting diode 31, and the lighting by the high beam unit 3 is limited. In the other zones, illumination at a light intensity required by the light beam L of the white light-emitting diode 31 is produced. Consequently, the driving beam light distribution control with an adaptive driving beam is carried out in which visibility of the front area of the automobile is improved without dazzling the approaching vehicle CAR or the pedestrians Ml, M2 used. as an object.
    When the light switch SW is open from "high beam adaptive driving beam" at time t4 in Figure 5, the low beam unit 2 is turned off by the first part of the circuit lighting 51. At the same time, the second part of the lighting circuit 52 stops the emission of light from the second white light-emitting diode 31, the part of the motor control circuit 53 stops the rotation of the motor 34, and the high beam unit 3 is off.
    Switching from "low beam" to "high beam adaptive driving beam"
    In FIG. 5, when the light switch SW is placed on "low beam" at an instant t5, that is to say when the high beam unit 2 is on and the rotating mirror 35 is in same time driven in rotation at the predetermined speed, when the switch is also switched to "high beam adaptive driving beam" at an instant t6, the second part of the lighting circuit 52 controls the second white light emitting diode 31 of the high beam unit 3 for emitting light. Therefore, the light from the second white light emitting diode 31 is scanned by the rotating mirror 35 to turn on the high beam unit 3, and lighting with the high beam light distribution shown in Fig. 2B is achieved .
    At this time, the second part of the lighting circuit 52 refers to the speed of rotation of the rotating mirror 35 detected by the detection part of the rotating mirror 54 at time t6 when the lighting switch SW is switched. However, since the rotating mirror 35 has already started the rotation at time t5 when the "low beam" is started, and the speed of rotation is controlled at the predetermined speed at time t6, the second circuit part d lighting 52 immediately controls the second white light emitting diode 31 to be on. Therefore, lighting with a high beam light distribution which does not instantly cause the sensations of abnormality and discomfort is achieved.
    Return from "high beam adaptive driving beam" to "low beam" In Figure 5, when the light switch SW is switched from "high beam adaptive driving beam" to "high beam dipped beam ”at an instant t7, the second part of the lighting circuit 52 stops the emission of light from the second white light-emitting diode 31, and switches off the high beam unit 3. The“ low beam ”state is therefore restored.
    In this case also, while being controlled by "low beam", the rotating mirror 35 continues to rotate at the predetermined speed of rotation under the control of the motor control circuit part 53. Consequently, even when the light switch SW is again set to "adaptive driving beam high beam" at time t8 from the "low beam" state, the control of the high beam light distribution can be switched instantly, and at that time, lighting with an "adaptive driving beam main beam" can be achieved without causing the sensations of anomaly and discomfort.
    When the light switch SW is open from "high beam adaptive driving beam" at an instant t9, the low beam unit 2 is turned off by the first part of the lighting circuit 51 At the same time, the second part of the lighting circuit 52 stops the emission of light from the second white light-emitting diode 31, the part of the motor control circuit 53 stops the rotation of the motor 34, and the unit of main beam 3 is off.
    As described above, in this embodiment, since the rotating mirror 35 of the high beam unit 3 is rotated simultaneously with the ignition of the low beam unit 2 , the rotation of the rotating mirror 35 is continued even when the distribution of low beam light by "low beam" and the distribution of high beam light with adaptive driving beam by "high beam with adaptive driving beam" are frequently switched. Consequently, in particular, it is not necessary to consider the rise time Ts of the rotating mirror 35 when switching to "high beam with adaptive driving beam", the lighting control "high beam with beam adaptive driving ”can be done quickly, and feelings of anomaly and discomfort can be avoided at the same time.
    In addition, even when "low beam" and "high beam adaptive driving beam" are switched to a time interval longer than a first time or a second time proposed in the previous application, since the rotation of the rotating mirror 35 is continued, the lighting control “high beam with adaptive driving beam” can be carried out quickly, and the sensations of anomaly and discomfort can at the same time be avoided.
    In addition, in this embodiment, the motor 34 which rotates the rotating mirror 35 generates a so-called inrush current at the start of the rotation, and energy consumption becomes excessive. However, total energy consumption can be reduced by continuously running the motor 34 at the time of the "low beam". In addition, a life of the motor 34 is also affected by the number of ON / OFF repetitions, which is advantageous in increasing the life of the motor 34 or of the rotating mirror 35.
    As shown in Figure 7, when "high beam adaptive driving beam" is achieved on the basis of the speed of rotation of the rotating mirror 35, a threshold speed Th can be established at a lower speed at the predetermined speed of rotation, and “high beam with adaptive driving beam” can be produced when the threshold speed Th is reached. This is due to the fact that, even if the speed of rotation of the rotating mirror 35 at the start of the lighting is slightly lower than the predetermined speed of rotation, the light distribution is less affected. Therefore, the rise time Ts can be shortened to allow rapid lighting control.
    Here, as shown in a timing diagram of Figure 8, when the command "low beam" started at time tl 1 is stopped at a time 112, the rotation of the motor 34 is ie the rotation of the rotating mirror 35, can be continued for a predetermined additional time Ta. In this way, in a case where “low beam” is produced again at time 113 after a time shorter than the additional time Ta, the following “low beam” command is carried out while the rotation of the rotating mirror 35 is continued, and the rotation of the rotating mirror 35 is not frequently stopped.
    Even in a case where "high beam adaptive driving beam" is established at an instant tl5 during the additional time Ta after an instant tl4 when "low beam" is finished, the speed of rotation of the rotating mirror 35 is maintained at the predetermined speed at this time, so that the lighting with "high beam adaptive driving beam" can be instantly realized, and no feeling of anomaly and discomfort occurs. The same applies to the case after "adaptive driving beam main beam" is completed at time tl6.
    In this case, the speed of rotation of the motor 34 can be reduced during the additional time Ta. Therefore, power consumption can be reduced by reducing the rotational speed, while the rise time Ts can be shortened when the motor 34 is then started to run and driven at the predetermined speed.
    The first light and the second light in the present invention are not limited to the high beam and the high beam light described in the embodiment. In particular, the second light can be a light comprising scanning means which scan the light emitted by the light source. In addition, when the second light is configured as a high beam, it may not always be necessary to perform the adaptive driving beam light distribution control.
    The scanning means according to the present invention are not limited to the rotating mirror described in the embodiment, and the present invention can be applied to all the scanning means as long as the scanning means use a motor or any other actuator, which needs a predetermined rise time when starting the light scan, as a drive source.
    In the embodiment, the object detection device 4 is configured in one piece with the headlight, but the object detection device can be configured separately from the light. In addition, the lighting control device 5 can also be configured separately from the light.
