An Adaptive Driving Beam System with Integrated Automatic Lamp Control Function

The abuse of automotive high beam can cause dazzling to the driver and enormously increase the traffic accident risk at night. To improve driving safety, The Adaptive Driving Beam (ADB) technique is proposed in recent years. According to the traffic information gathered from the frontal camera, the ADB system can form a proper high beam shadow area by turn off specific LED groups. The shadow area can track the preceding vehicle until the vehicle leave the sights of the high beams. In this paper, An ADB system integrated with automatic headlight control strategy is presented. The principle of ADB is established on the coordinate transformation from the frontal camera to the left and right high beams. The status of high beam and ADB function is determined by the vehicle real-time status and the setting of the Head Unit (HU). The hardware architecture of ADB system is also discussed. The ADB system proposed can provide a full function of high beam control, and reduce the abuse risk of high beam effectively.
