    Throttle valve opening control device of an internal combustion engine {THROTTLE VALVE CONTROL SYSTEM FOR INTERNAL COMBUSTION ENGINE}
    The present invention relates to a throttle valve opening degree control device of an internal combustion engine, and more particularly, to a throttle valve opening degree control device of an internal combustion engine having an improved working structure of a throttle valve for intelligent speed adaptation.
    In general, the Intelligent Speed Adaptation (ISA) is wirelessly received from a speed limiter installed on the road, and when the vehicle's driving speed exceeds the speed limit, it forcibly decelerates to the speed limit and then the driver's accelerator pedal operation is stopped. Even if it is a device that limits it.
    Such a device is reflected in the national road policy, and thus the opening control device of the throttle valve applied to the ISA device is shown in FIG.
    The throttle valve opening degree control device 2 is applied to the electronically controlled throttle body 4.
    The throttle valve opening degree control device 2 includes a throttle valve 6, a rotation shaft 8 that transmits rotational force to the throttle valve 6, and an accelerator pedal 10 and an accelerator cable 12 on one side of the rotation shaft 8. The first rotary plate 14 connected to the first rotary plate 14 and the second rotary plate connected to the motor 18 and the throttle cable 20 operating as control signals of the electronic controller 16 on one side of the first rotary plate 14. 22).
    That is, the throttle valve opening control device 2 is provided with first and second rotary plates 14 and 22 to maintain a complementary function in order to control the opening degree of the throttle valve 6 in the fail-safe side. A plurality of cables 12 and 20 are connected in a structure.
    This throttle valve opening control device 2 is operated in three modes of operation.
    Mode 1 is a conventional mechanical mode without electronic control;
    This controls the opening of the throttle valve 6 by the driver's accelerator pedal 10, that is, the first rotating plate 14 is rotated through the accelerator cable 12 at the driver's accelerator pedal 10.
    As the rotation shaft 8 rotates by the rotation of the first rotating plate 14, the throttle valve 6 is opened by the stepped amount of the accelerator pedal 10.
    At this time, the motor 18 is connected to the second rotating plate 22 and the throttle cable 20, but because the power is not applied by the electronic control device 16 affects the rotational operation of the first rotating plate 14 The opening degree of the throttle valve 6 by the step of the accelerator pedal 10 is made free.
    Mode 2 is a mode of operation by pure electronic control;
    The electronic controller 16 determines that there is no driver's operation or senses the state of the vehicle through each sensor to apply power to the motor 18 to control and rotate the second rotating plate 22 through the throttle cable 20. Let's do it.
    The rotary shaft 8 rotates by the rotation control of the second rotating plate 22 to open the throttle valve 6 to maintain the running state of the vehicle.
    At this time, since the first rotary plate 14 is also integrally installed on the rotary shaft 8 when the second rotary plate 22 is rotated, the accelerator pedal 10 is operated even if the driver does not step the accelerator pedal 10. Therefore, it is interlocked.
    Mode 3 is a case where a mechanical mode and an electronically controlled mode are mixed;
    When the electronic controller 16 determines and additionally controls the driver's accelerator pedal 10 in response to the driver's stepping operation, the driver's priority is applied.
    That is, when the first rotary plate 14 is rotated and opened at a predetermined angle by the accelerator pedal 10 operated by the driver, for example, when the opening angle of the throttle valve 6 is 30 °, the motor 18 The second rotating plate 22 may not affect the first rotating plate 14 at less than 30 °, and if the second rotating plate 22 is greater than 30 °, the second rotating plate 22 may affect the rotation of the second rotating plate 22 instead of the first rotating plate 14. It will be made more than 30 °.
    In this conventional technique, the structure of the electronically controlled throttle valve is controlled by the driver's first principle so that the driver speeds up when operating like Mode 3, and the speed of the throttle valve opening is forcibly reduced to an appropriate speed by using an opening motor of the throttle valve. There is a problem that cannot be controlled.
    Therefore, the present invention is invented to solve the problems as mentioned in the prior art, the object of the present invention is to wirelessly receive the speed limit installed on the road to reduce the speed to the speed limit forcibly when the speed of the vehicle exceeds the speed limit Then, as a device for limiting the accelerator pedal operation even if the driver is to provide a throttle valve opening control device of the internal combustion engine.

    Figure 2 is a schematic view of the present invention throttle valve opening degree control device.
    Figure 3 is a flow chart showing the operation of the throttle valve opening degree control device according to the present invention.
    4 shows a prior art;
    The present invention for realizing this in the throttle valve opening degree control device of the internal combustion engine,
    Accelerator pedal switch to sense the amount of stepped pedal accelerator,
    The internal combustion engine is formed by directly installing a drive means controlled by an electrical signal of an electronic controller that recognizes the stepped amount of the accelerator pedal switch on one side of the rotary plate which is connected to the rotary shaft by the accelerator pedal and the accelerator cable to open the throttle valve. The throttle valve opening for the IS is also provided.
    According to the present invention, the electronic control device determines whether the driver controls the operation by applying an electric signal to the driving means and wirelessly receives the speed limit installed on the road to determine the opening of the throttle valve when the speed of the vehicle exceeds the speed limit. By forcibly reducing the angle, it maintains an appropriate opening angle to decelerate the vehicle speed.
    Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.
    1 is a perspective view showing a throttle valve opening degree control apparatus according to the present invention, Figure 2 is a view schematically showing a throttle valve opening degree control apparatus according to the present invention.
    The throttle valve opening degree control device 30 is one end of the rotary shaft 34 of the rotary plate 40 is connected to the rotary shaft 34 by the accelerator pedal 36 and the accelerator cable 38 to open the throttle valve 32. Is provided by directly installing a motor 44 which is a driving means controlled by an electrical signal of the electronic control device 42.
    The motor 44 may use a step motor or the like, or may be electronically controlled.
    An accelerator pedal switch 46 for sensing the stepped amount of the accelerator pedal 36 is provided to provide the electronic controller 42 with the stepped amount information of the accelerator pedal 36 as an electrical signal.
    In the present invention made as described above, the flow of determination of the electronic control device 42 will be described with reference to FIG. 3. The operation of the driver's accelerator pedal 36 is determined (S10), and when there is an operation, the accelerator pedal switch 46. Through the electronic control device 42 recognizes the stepped amount.
    When the electronic controller 42 detects the answer of the accelerator pedal 36, the electronic controller 42 determines whether the electronic control operation is performed again (S20), and if the electronic control operation is performed, the mode is changed into the mechanical and electronic mixed mode. Set to S30 to drive the vehicle.
    If it is determined that the next electronic control operation with the driver's accelerator pedal 36 is not performed (S20), the electronic controller 42 sets the mechanical mode S40 to drive the vehicle.
    Further, if it is determined that the driver's accelerator pedal 36 has not been operated (S10), and there is an electronic control operation (S50), the electronic controller 42 sets the electronic control mode (S60) to drive the vehicle.
    If it is determined that there is no electronic control operation in the state in which no accelerator pedal 36 is stepped (S50), the controller moves to the first step and repeatedly determines whether the driver has operated.
    In the throttle valve opening degree control device 30, when the mechanical and electronic mixing mode S30 is performed, the power of the motor 44 is greater than that of the driver's accelerator pedal 36. Control operation is led.
    At this time, the stepped amount information of the accelerator pedal 36 sensed by the accelerator pedal switch 46 is recognized by the electronic controller 42 and reflected in the motor 44 control.
    In contrast to the above operation, even when the driver's accelerator pedal 36 is operated when the motor 44 is operated by the signal of the electronic controller 42 and the electronic controller is operated, the motor 44 is operated as described above. According to the large power of the accelerator pedal 36, even if the answer is made, the electronic control operation is made without restriction.
    In other words, this is because the pedal 36 of the driver is reflected by the accelerator pedal switch 46.
    In the mechanical mode S40, the power applied to the motor 44 by the electrical signal of the electronic controller 42 is cut off.
    Accordingly, the rotation shaft 34 connected to the motor 44 may freely rotate without being loaded when the driver's accelerator pedal 36 is operated, thereby adjusting the opening angle of the throttle valve 32.
    In addition, in the electronic control mode S60, the opening degree of the throttle valve 32 is made by electronic control in a state where power is applied to the motor 44 by an electrical signal of the electronic control apparatus 42. FIG.
    At this time, when the rotary shaft 34 is rotated by the operation of the motor 44, the rotary plate 40 also rotates, and the accelerator pedal 36 connected to the accelerator cable 38 is also linked thereto.
    The accelerator pedal 36 has a phenomenon in which the operation of the motor 44 is repeated several times when the operation of the motor 44 is not inconvenient unless the operation of the operation by the driver is inconvenient. (Repeat operation similar to ABS, an electronic brake)
    As described above, the electronic controller 42 determines whether the driver's accelerator pedal 36 is operated by the driver, and then applies an electrical signal to the motor 44 to control the operation, thereby wirelessly transmitting the speed limit signal installed and transmitted on the road. When the speed of the host vehicle exceeds the speed limit by receiving, the opening angle of the throttle valve 32 is forcibly reduced to maintain the proper opening angle, thereby decelerating the vehicle speed to promote safe driving.
    On the contrary, when the vehicle travels in a state not exceeding the specified speed limit, the vehicle maintains a normal driving state.
    The present invention has the effect that the electronic throttling can be precisely performed since the throttle opening degree can be increased / decreased electronically and directly connected to the motor and the rotating shaft.
    On the fail-safe side of the motor, it can be detected by the accelerator pedal switch to reflect the amount of stepping.
    The process is omitted since one cable is deleted by directly connecting the motor to the rotating shaft provided with the throttle valve, which results in weight reduction and cost reduction.
