Embodiment 1
[0021] like Figure 1-2 As shown, the present embodiment provides an ADB headlight system, including a camera module, an electronic control unit, a CAN bus, a power supply line and a vehicle light, the camera module is connected to the vehicle light through the CAN bus, and the electronic control unit is connected to the vehicle light through the CAN bus. The power supply line is connected to the headlights. When the high beam needs to be turned on, the electronic control unit is responsible for supplying power to the high beam, and the camera module is responsible for sending control instructions to each LED of the high beam through the CAN bus to realize the high beam. The light function and the ADB function of adaptive high beam, wherein, the camera module includes an image processing module, a light detection module, an ADB processing module, a dimming module and a CAN bus message sending module, and the image processing module is connected to the The light detection modul...
Embodiment 2
[0024] This embodiment provides a control method for an ADB headlamp system, and the operation steps of each module in the camera module are as follows:
[0025] Step 1: When an object appears in the camera module detection area, the image processing module is responsible for detecting the object and periodically updating the state of the object;
[0026] Step 2: The light detection module distinguishes and calculates the type of the object (same-way vehicle / opposite vehicle), the distance of the object, the horizontal angle of the object, and the vertical angle of the object according to the light emission of the object;
[0027] Step 3: Integrate the ADB processing module in the ADB algorithm controller in the existing ADB system into the camera module; the ADB processing module calculates the smallest shadow area that can cover the entire object according to the information of the object, that is, the left shadow area Boundary Angle and Right Boundary Angle;
[0028] Step ...
