[0025] Embodiments

[0026] The specific implementation is as follows:

[0027] As Figure 1 The structure of the automobile AFS and CMS camera linkage adjusting device provided by the embodiment of the application is shown.

[0028] As an example, the linkage adjustment device comprises: an adaptive front-lighting system 1 (AFS), a car light controller 2 and a camera monitor system 3 (CMS); the output end of the adaptive front-lighting system 1 is electrically connected with the input end of the car light controller 2, and the output end of the car light controller 2 is electrically connected with the input end of the camera monitor system 3; the camera monitor system 3 is integrated with a motor controller 300, a camera motor 310 and a camera 320 placed outside the car, the input end of the motor controller 300 is electrically connected with the input end of the car light controller 2, the output end of the motor controller 300 is electrically connected with the input end of the camera motor 310, and the output end of the camera motor 310 is electrically connected with the camera 320 placed outside the car; the adaptive front-lighting system 1 is used for sending an AFS motor angle signal to the car light controller 2; the car light controller 2 is used for sending the AFS motor angle signal to the motor controller 300 after signal processing; and the motor controller 300 is used for controlling the camera motor 310 to drive the camera 320 to rotate based on the AFS motor angle signal after signal processing. Specifically, the camera 320 of the car CMS cooperates with the AFS rotation angle signal through a hardware circuit, obtains current vehicle motion information and transmits the information to the car light controller 2, the car light controller 2 transmits the signal to the CMS camera motor controller 300 after processing, the CMS camera motor controller 300 processes the signal, thereby adjusting the deflection angle of the external camera 320 and collecting external road condition information. That is, in the normal driving process, the deflection angle of the CMS external camera is adjusted according to the AFS deflection angle, and when the vehicle motion trajectory changes (such as turning, U-turn and lane changing), the situation of other lanes can be accurately observed, and traffic accidents caused by limited field of view can be avoided.

[0029] In some possible embodiments, the car light controller 2 is integrated with an MCU controller, and the MCU controller is used for starting to collect the AFS motor angle signal based on a collected turn signal of the vehicle. That is, to avoid that the CMS external camera motor 310 receives an abnormal signal, a starting condition (i.e., a turn signal) is added, and only after receiving the turn signal, the driver enters the normal working mode, thereby avoiding that the angle adjustment of the external camera 320 is triggered in the parking turning and lane driving and other turning actions of the vehicle. After receiving the turn signal and starting to turn, the AFS motor angle signal is synchronized in real time, and the synchronized data is sent to the car light controller 2 through CAN communication.

[0030] In some possible implementation manners, the MCU controller is further configured to filter the received AFS motor angle signal and the turn signal. Specifically, the vehicle lamp controller 2 processes the input information, and first filters the turn signal to avoid false start caused by noise. For the low beam AFS motor angle signal, the signal is sent every 10 ms, and bubble sorting is performed on the data to remove noise. The processed data is subjected to sliding filtering to avoid the case that the motor and the CMS move rapidly due to rapid turning and rapid data increase.

[0031] In some possible implementation manners, the adaptive front light system 1 is connected to the vehicle lamp controller 2 through CAN communication.

[0032] In some possible implementation manners, the vehicle lamp controller 2 is further configured to send the AFS motor angle signal to the motor controller 300 through SPI protocol after signal processing.

[0033] In some possible implementation manners, the vehicle lamp controller 2 and the motor controller 300 can be separately connected through a CAN bus and other functional lines to realize motor movement of the lamp driving control CMS external camera, facilitate subsequent program refreshing, and controller version updating.

[0034] In some possible implementation manners, the camera monitoring system 3 further integrally has an electronic control unit 330, an output end of the electronic control unit 330 is electrically connected to the camera 320, and the electronic control unit 330 is configured to control the on-off state of the camera 320 based on collected vehicle running state information. That is, when the electronic control unit 330 receives that the vehicle is in an on state, the camera 320 is controlled to be in an on state, and when the electronic control unit 330 receives that the vehicle is in an off state, the camera 320 is controlled to be in an off state, thereby avoiding overuse of the camera 320.

[0035] In some possible implementation manners, an output end of the electronic control unit 330 is further electrically connected to the motor controller 300, and the electronic control unit 330 is configured to send a reset signal to the motor controller 300 based on the fact that the vehicle is in an off state, so that the motor controller 300 controls the camera motor 310 to reset the camera 320. That is, the camera 320 is automatically reset after the vehicle is turned off, which not only avoids this risk, but also avoids natural wear and tear caused by long-term exposure, thereby greatly increasing the service life.

[0036] In some possible implementation manners, the camera 320 placed outside the vehicle is further electrically connected to a display unit placed inside the vehicle through the electronic control unit 330, and the camera 320 is configured to transmit image information collected by the camera 320 to the display unit inside the vehicle for display. Meanwhile, a collision warning can be issued on the display unit.

[0037] In some possible implementations, the camera monitoring system 3 is further integrated with a sensor unit 340, an input end of the sensor unit 340 is electrically connected with an output end of the camera 320, and an output end of the sensor unit 340 is electrically connected with the motor controller 300, and the sensor unit 340 is used to feed back position information of the camera 320 to the motor controller 300, wherein the sensor unit 340 is integrated with a position sensor and an angle sensor.

[0038] The utility model can obtain the current AFS deflection angle through CAN signal acquisition, and transmit the collected data to the vehicle light controller, and send the signal after the vehicle light controller processes to the CMS camera motor controller, adjust the external camera deflection angle to collect the road condition information in real time, and show through the internal display, so that the driver can accurately observe the other lane situation in the steering or U-turn process, prevent the limited field of vision. When there is a collision risk, the display issues a collision warning, timely reminds the driver, and avoids the occurrence of the accident.

[0039] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme and the utility model concept of the utility model, equivalent replacement or change, should be covered in the protection scope of the utility model.
