Problems solved by technology

[0003] In the current architecture, the ADB algorithm control, the initialization time of the car light controller software, and the bus transmission time will all cause an inevitable delay in the entire ADB system from the appearance of the object to the formation of the shadow area, which leads to the delay from the appearance of the object to the formation of the shadow area. It takes a long time, so there is a possibility that the vehicle in front is dazzled, which means that the ADB function is invalid

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 ...

Abstract

The invention provides an ADB headlamp system and a control method. Image processing, light detection, ADB processing and dimming are performed mainly through a camera and an internal software moduleof the camera, and a control command is output to an LED lamp panel through a CAN bus; and the dimming of each LED is directly controlled by the camera module, and the participation of an ADB algorithm controller and a vehicle lamp controller can be omitted so that the system delay time is effectively shortened.

Description

technical field [0001] The invention relates to the field of automobile lamps, in particular to an ADB headlamp system and a control method. Background technique [0002] With the development of automotive electronic technology, more and more attention has been paid to safety and comfort, so Advanced Driving Beam (ADB) technology has emerged as the times require. While ADB technology satisfies driving needs to the greatest extent, it prevents high beams from dazzling other drivers, improves driving comfort, and reduces potential safety hazards. like figure 1 As shown, in the existing ADB system architecture, a camera module, an ADB algorithm controller, a car light controller, and a car light are configured. The camera module software is responsible for outputting the detected object information, and the ADB algorithm controller according to the camera module The sent object information calculates the shadow area that needs to be established and sends it to the light contr...
