The invention belongs to the technical field of vehicle electronic rearview mirrors, and particularly relates to a vehicle-mounted electronic rearview mirror and a control circuit thereof.The control circuit comprises a power supply circuit and a detection circuit, the control end of the power supply circuit is used for being connected with the wake-up signal output end of a vehicle, and the output end of the detection circuit is also used for being connected with the wake-up signal output end of the vehicle; the wake-up signal output end is used for outputting a preset left-end signal or a right-end signal and controlling the power supply circuit to be switched on when the wake-up signal is effective, and meanwhile, the output end of the detection circuit is used for being connected with a control unit of the electronic rearview mirror so as to collect the wake-up signal to run a program on the corresponding side. By arranging the control circuit, power can be supplied to the electronic rearview mirror, meanwhile, the picture needing to be displayed by the electronic rearview mirror is automatically recognized as the picture of the camera on the left side or the right side of the vehicle, a program on the corresponding side is operated to carry out the display process of the electronic rearview mirror, and then external interfaces of the control circuit are correspondingly connected to control the electronic rearview mirror. The electronic rearview mirror can be controlled.
本发明属于车辆电子后视镜技术领域,具体涉及一种车载电子后视镜及其控制电路,控制电路包括供电电路与检测电路,供电电路的控制端用于连接车辆的唤醒信号输出端,检测电路的输出端也用于连接车辆的唤醒信号输出端,且唤醒信号输出端用于输出预设的左端信号或右端信号,并在唤醒信号有效时,控制供电电路导通,同时检测电路的输出端用于连接电子后视镜的控制单元,以采集唤醒信号,来运行对应侧的程序。通过设置上述控制电路,能够为电子后视镜供电的同时,自动识别电子后视镜需要显示的画面为车辆左侧还是车辆右侧摄像头画面,以运行对应侧程序来进行电子后视镜的显示过程,进而将控制电路的对外接口对应连接后,能够对电子后视镜进行控制。
