Anti-dazzling system for geometric multiple-beam LED high beam of new energy vehicle and method

Abstract

The invention discloses an anti-dazzling system for a geometric multiple-beam LED high beam of a new energy vehicle and a method. An infrared thermogram output end of a thermal infrared imager is connected with an input end of a barrier positioning unit; an output end of the barrier positioning unit is connected with the input end of a lamp bead controller; the output end of the lamp bead controller is connected with all the controlled LED lamp beads; the lamp bead controller is used for selecting a set of LED lamp beads with the irradiating scope exactly covering the horizontal irradiation scope and longitudinal irradiation scope occupied by the barrier. The anti-dazzling system provided by the invention can solve the dazzling problem by self-adaptively turning off the appointed lamp beads in an array according to the positions of the vehicles and pedestrians under the condition of keeping the high-beam high light illumination; the anti-dazzling system has an excellent night driving illuminating effect and is safe; the thermal infrared imager is used for detecting the vehicles and the pedestrians at night; under the special use environment, such as, at night, compared with the traditional camera image recognition technique, the thermal infrared imager is higher in accuracy.

Description

technical field [0001] The invention relates to the field of automotive lighting, in particular to an anti-glare system and method for geometric multi-beam LED high beam lights of new energy vehicles. 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...

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
