Vehicle headlamp high beam self-adaptive control system

Abstract

The invention discloses a vehicle headlamp high beam self-adaptive control system which comprises a man-machine interaction module, a vehicle lamplight control main control module, a vehicle road condition sensing module and an ADB headlamp array light source control module. The vehicle road condition sensing module comprises an ADAS camera unit, an ADAS camera unit and a target shielding information processing unit. A vehicle-mounted machine vision technology is utilized, traffic condition information of a road in front of a vehicle is obtained through the vehicle road condition sensing module, and a to-be-shielded ADB target on the road in front of the vehicle is sensed. Aiming at a rapid moving ADB target, the vehicle road condition sensing module performs target position polar coordinate transformation and position prediction processing to obtain processed ADB target effective shielding area information, the light control module receives the coordinate orientation information of the ADB shielding area and then converts the coordinate orientation information into on-off control of a single ADB array light source, and finally, headlamp self-adaptive control with a prediction mechanism is realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle headlamp control, in particular to a vehicle headlamp high beam self-adaptive control system. Background technique [0002] In recent years, with the development of technologies such as machine vision and matrix automotive headlight array light sources, and the market's demand for vehicle advanced driver assistance system (ADAS) functional equipment, higher requirements have been put forward for the vehicle's headlight lighting system. Requirements: [0003] 1) In nighttime conditions, the headlights of the own vehicle should be able to provide sufficient brightness for the forward vision lighting, so that the driver of the own vehicle can clearly see the traffic conditions of the road ahead; [0004] 2) The headlights of your own car should try to avoid dazzling other traffic users, and use the headlights of your own car in a standardized and civilized manner, so as to reduce traffic accidents. ...

AI Technical Summary

Problems solved by technology

[0008]1) The accuracy and real-time performance of traffic user position recognition in the vehicle's forward field of vision are low;

[0009]2) When the traffic user to be covered is a moving target, the quick response of the vehicle's high beam local on and off control is poor;

[0010]3) When there are multiple occluded targets, effective occlusion cannot be achieved for each target
