Self-adaptive high beam control system and method based on infrared camera technology

Abstract

The invention discloses a self-adaptive high beam control system and method based on an infrared camera technology, and belongs to the technical field of car intelligent forward lighting. The self-adaptive high beam control system comprises an infrared camera, a radar, a vehicle speed sensor, a central control unit, and a high beam and low beam switching device. The control method comprises the steps that 1, image information in front of a vehicle is collected through the infrared camera and processed, whether non-motor vehicles and pedestrians exist in front of the vehicle or not is judged, and the specific positions of the non-motor vehicles and the pedestrians are determined; 2, according to the judging result of the step 1, the relative distance L and the relative speed V of the non-motor vehicles or the pedestrians in front and the vehicle are detected through the radar, the state of the non-motor vehicles or the pedestrians in front are judged, and the irradiation state of a headlight at the next moment is determined; and 3, high beam and low beam state delay switching control is conducted according to the irradiation state of the vehicle headlight at the moment and the irradiation state of the vehicle headlight at the next moment. According to the self-adaptive high beam control system and method based on the infrared camera technology, visual disorder caused by a high beam to drivers of the non-motor vehicles and the pedestrians is reduced, and night driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle front lighting, in particular to an adaptive high beam switching control system and method. Background technique [0002] The front lighting system of the vehicle allows the driver to clearly observe the road conditions when driving at night, which improves the safety of driving at night. The traditional front lighting system can artificially switch the high and low beams. When there is an oncoming car or a car in front, the driver will switch the low beams to avoid affecting other drivers and reduce the occurrence of accidents. However, due to the bad driving habits of some drivers, it is difficult to accurately switch the high and low beams when driving at night. If the driver fails to switch to the dipped headlights accurately and timely when a vehicle is approaching in the opposite lane, it will affect the driver's sight in the opposite lane and cause an accident.

It does not take into account the impact of non-motor vehicles and pedestrians on high beams

[0005] At this stage, the adaptive high beam system is often only aimed at the high and low beam changes of motor vehicles, ignoring the danger of non-motor vehicle drivers and pedestrians with limited vision and accidents when they are illuminated by high beams.
