Dot-matrix laser headlamp control system and method for vehicle meeting

Abstract

The invention discloses a dot-matrix laser headlamp control system and method for vehicle meeting. The dot-matrix laser headlamp control system for vehicle meeting comprises laser headlamps which aremounted at vehicle headlamps, control units, receivers and executers. The input ends of the control units are connected with the laser receivers, and the output ends of the control units are connectedwith the executers. The output ends of the executers are connected with the laser headlamps, and the laser headlamps each comprise a first arc-shaped panel and a laser light source arranged on the first arc-shaped panel. The laser light sources are distributed in a dot-matrix mode, and the receivers internally comprise photoelectric elements which correspond to the laser light sources in a one-to-one mode and are used for measuring the irradiation distances of the corresponding laser light sources. According to the dot-matrix laser headlamp control system and method, the irradiation light intensity of high beams can be intelligently weakened to prevent the situation that glare occurs to an opposite vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle lights, in particular to a dot-matrix laser headlight control system and control method for meeting vehicles. Background technique [0002] With the continuous improvement of people's living standards, the popularity of cars has become wider and wider. More and more families have their own vehicles. In the process of driving, traffic safety is always the most important. Among them, driving at night Sometimes, inappropriate use of high beam lights will often find a strong stimulus to the eyes of the drivers of the participating vehicles, making them temporarily blind, thus easily causing traffic accidents, and due to the poor natural light in the night environment, the high beam lights Using is a better self-protection method, but artificially controlling the far and near light to switch, its operation is more troublesome and error-prone, for this reason Chinese patent CN103192759A discloses a kind...

[0002] With the continuous improvement of people's living standards, the popularity of cars has become wider and wider. More and more families have their own vehicles. In the process of driving, traffic safety is always the most important. Among them, driving at night Sometimes, inappropriate use of high beam lights will often find a strong stimulus to the eyes of the drivers of the participating vehicles, making them temporarily blind, thus easily causing traffic accidents, and due to the poor natural light in the night environment, the high beam lights Using is a better self-protection method, but artificially controlling the far and near light to switch, its operation is more troublesome and error-prone, for this reason Chinese patent CN103192759A discloses a kind of area array LED car light control system and Its control method; the area array LED car light control system and its control method for meeting cars at night include an area array LED car light installed at the position of the vehicle headlight, an environmental detector, an electronic control unit ECU, an actuator and an information output equipment, the input end of the electronic control unit ECU is connected to the output end of the environment detector, the corresponding output end of the electronic control unit ECU is respectively connected to the input end of the actuator and the information output device, and the actuator The output end is connected to the area array LED lights; the angle and brightness of the LED lights can be automatically adjusted according to the driving environment when the vehicles meet at night, so as to improve the safety of meeting cars at night

However, this method also has some shortcomings. It realizes the switching between the far and low beams, and intelligently switches the low beams when meeting cars. The state of the low beam light causes the own field of vision to become smaller, and there is a relative safety problem for the own vehicle on the road section with very bad light; moreover, the irradiation distance of the LED car light is relatively general, providing the driver with a limited visual field of view , although the use of millimeter-wave radar is sensitive, it is prone to failure in places with relatively high magnetic fields
