Description

Control system, control method and computer equipment of self-adaptive high beam Technical Field The invention relates to the technical field of automobile illumination, in particular to a control system, a control method and computer equipment of a self-adaptive high beam. Background ADB (ADAPTIVE DRIVING Beam) self-adaptive high Beam is an intelligent high Beam control system capable of adaptively changing high Beam patterns according to road conditions. The method changes a complete high beam spot into a high beam spot composed of a plurality of optical illumination components through a special optical module and electronic control. When targets such as vehicles and pedestrians appear on the road, a control system consisting of a sensor (camera) and a driving circuit turns off or dims part of the high beam illumination subareas, so that the glare to the illuminated targets is avoided, and meanwhile clear high beam illumination is ensured. The ADB self-adaptive high beam system judges the position and distance of the opposite vehicle through the input of the camera signal, and makes an automatic adjustment light irradiation area, and closes or dims the light irradiation instruction of the opposite vehicle area. The existing control method of the self-adaptive high beam has the following defects: (1) The parameters of the existing ADB control algorithm are mostly fixed values or need manual calibration, and cannot be dynamically adjusted according to real-time road conditions (such as multi-target intersection and vehicle speed change), so that the phenomenon of response lag or excessive response is easy to occur. (2) When multiple targets such as opposite vehicles, same-direction vehicles and roadside pedestrians exist on the road at the same time, the conventional ADB control algorithm is difficult to consider the anti-dazzle requirements of all the targets, and the problems of partial target glare or insufficient self vision are easy to occur (such as shielding the opposite vehicle region only and neglecting the light intensity control nearby the pedestrians). (3) ADB system response speed under the existing algorithm is slow, and when facing to a scene of high-speed running (for example, the speed is more than 100 km/h) or a scene of fast movement of a target (for example, a pedestrian crosses a road), the output of an adjusting instruction is delayed, so that glare cannot be avoided in time. (4) The existing ADB control algorithm mostly adopts a target shielding priority strategy (such as priority guarantee of anti-dazzle of opposite vehicles), the effective field of view of a driver is easy to sacrifice (such as insufficient road surface illumination caused by excessive shielding), and a global optimal solution is not formed. Disclosure of Invention The invention aims to solve the technical problems that the existing ADB control algorithm has poor response, poor anti-dazzle demand control and the like, and provides a control system, a control method and computer equipment of a self-adaptive high beam lamp, which can overcome the defects of the prior art.
