System and method for controlling planar array LED vehicle lamp for vehicle meeting at night

Abstract

The invention relates to the lighting technology for vehicles, and discloses a system and a method for controlling a planar array LED vehicle lamp for vehicle meeting at night. The system for controlling the planar array LED vehicle lamp for vehicle meeting at night comprises the planar array LED vehicle lamp, an environmental detector, an electronic control unit ECU, an actuator and information output equipment. The planar array LED vehicle lamp is mounted at a headlamp of a vehicle, an input end of the electronic control unit ECU is connected with an output end of the environmental detector, corresponding output ends of the electronic control unit ECU are respectively connected with an input end of the actuator and an input end of the information output equipment, and an output end of the actuator is connected with the planar array LED vehicle lamp. The system and the method have the advantages that an angle and the brightness of the LED vehicle lamp can be automatically adjusted according to a driving environment of the vehicle during vehicle meeting at night, and the safety of vehicle meeting at night is improved.

Description

technical field [0001] The invention relates to vehicle lighting technology, in particular to an area array LED vehicle light control system and a control method for meeting vehicles at night. Background technique [0002] When driving at night, due to poor natural light and poor lighting, it is difficult for drivers to observe. What's more, driving at night often has to meet cars. Generally, vehicles are equipped with high beams of 75W, and the distance to see objects is about 50-60 meters, and low beams are 55W, and the distance to see objects is about 15-20 meters. The light adaptation time of a person is about a few seconds, and the dark adaptation time is about a few minutes or even longer. During the meeting process, if the dipped beam is not switched in time, the drastic changes in light and shade will strongly stimulate the driver's eyes, causing the driver's short-term visual blindness, which may easily lead to traffic accidents. In addition, in the case of a cur...

AI Technical Summary

Problems solved by technology

During the meeting process, if the low beam headlights are not switched in time, the sharp changes in light and darkness will strongly stimulate the driver's eyes, causing the driver's short-term visual blindness, which may easily lead to traffic accidents

In addition, in the case of a curve, the simple conversion of far and near light cannot meet the lighting requirements of the road surface, so the light needs to be shifted to the turning direction

At present, relevant research fails to consider factors such as road alignment and light brightness distribution, and there are still great hidden dangers to the safety of cars meeting at night
