Geometric multi-beam LED high beam light anti-dazzling system of new-energy automobile

Abstract

The invention discloses a geometric multi-beam LED high beam light anti-dazzling system of a new-energy automobile. The infrared thermogram output end of a thermal infrared imager is connected with the input end of an obstacle positioning unit, the output end of the obstacle positioning unit is connected with the input end of a light bead controller, and the output end of the light bead controller is connected with all controlled LED light beads. The illumination range selected by the light bead controller right covers the set of the LED light beads in the transverse illumination range and the longitudinal illumination range occupied by obstacles. According to the geometric multi-beam LED high beam light anti-dazzling system of the new-energy automobile, on the premise of keeping high-brightness illumination of a high beam light, the dazzling problem is solved by self-adaptively turning off several appointed light beads in an array according to the positions of vehicles and pedestrians, and the good illumination effect and safety during night driving are achieved. The thermal infrared imager is used for detecting vehicles and pedestrians at night, and compared with the traditional camera image identification technology, the accuracy is higher in the special using environments such as night.

Description

technical field [0001] The invention relates to the field of automobile lighting, in particular to an anti-glare system for geometric multi-beam LED high beam lights of new energy automobiles. Background technique [0002] Headlights are an important part of a car, which can provide lighting for the car when driving in poor light, foggy weather or at night. Compared with the low beam, the light of the high beam is emitted in parallel, the light is concentrated and brighter, and can illuminate higher and farther objects, which is of great help to the driver's sight at night. However, the current phenomenon of abuse of high beams is quite serious. Using high beams at the wrong time will not only improve driving safety, but will cause short-term blindness to oncoming vehicles and pedestrians, and greatly increase the probability of dangerous accidents. . [0003] In order to solve the above technical problems, many high-end cars have begun to be equipped with adaptive high an...

Problems solved by technology

[0004] However, the traditional adaptive far and low beam switching technology only switches the car lights to low beams. The sudden switch from high beams to low beams will greatly shorten the driver's field of vision, especially when the car is driving at high speed. Due to the limited field of view of the low beam, it is difficult for the driver to make a timely prediction of obstacles outside the low beam field of view, and there are still great potential safety hazards
