An automobile headlight control system

Abstract

The invention provides a vehicle headlamp control system. The system comprises a vehicle lamp illumination system, a detection system and a control system. The vehicle lamp illumination system comprises a high beam, a low beam and an LED flash lamp. The detection system comprises a light intensity detection system, a vehicle speed detection system, a slope detection system and a pedestrian detection system, can intelligently control and comprehensively use a vehicle headlamp, and finishes vehicle headlamp intelligent selection and switching in a meeting mode, in a slope mode, when pedestrians are on a pavement and under various complex road conditions. The low beam and the high beam are selected according to the gradient of a slope, the vehicle headlamp is switched to the high beam in the downhill state so that the vision range can be widened, and the problem that vision is not clear when the low beam is used downhill is solved; the LED flash lamp reminds pedestrians in a dangerous distance range on the pavement, and pedestrian collision accidents are effectively reduced; light is selected automatically according to outside natural light intensity and light intensity of vehicles coming from the front, the headlamp is switched to the low beam when vehicles come, and traffic accidents are reduced.

Description

technical field [0001] The invention relates to a headlight control system, in particular to an automobile headlight control system, belonging to the technical field of automobile light intelligent control. Background technique [0002] With the popularization of automobiles, the proportion of driving accidents is also increasing year by year, and 70% of traffic accidents occur at night. When driving at night, the driver's sight range becomes narrow, and the ability to recognize dark objects will be significantly reduced. After studying most car collision accidents at night, it is concluded that if the driver can be a few seconds ahead of the accident If you are aware of the presence of pedestrians on the road and take corresponding correct measures, most accidents can be avoided. Therefore, it is very necessary to capture and prompt pedestrians at night in the vehicle assisted driving system. [0003] After the number of vehicles increases, the driving environment faced b...

AI Technical Summary

Problems solved by technology

The lack of intelligent control and comprehensive application of car headlights, the intelligent selection and switching of car headlights in various complex road conditions such as meeting mode, slope mode, and pedestrians on the road, etc., the switching of low beam and high beam is single , did not select low beams and high beams based on oncoming traffic conditions and road slopes, did not combine technologies such as pedestrian detection with intelligent control of car headlights, and did not use car headlights to remind pedestrians ahead

[0005] On the whole, the automotive headlight control system in the prior art mainly has the following defects: one is that it only completes the simple low beam and high beam switching, does not intelligently control the automotive headlights, and lacks the intelligence of the automotive headlights. Comprehensive application, did not complete the intelligent selection and switching of car headlights under various complex road conditions such as meeting mode, slope mode, and pedestrians on the road. The second is the lack of selection of low beam and high beam according to the slope of the road. It cannot automatically switch to high beam when going downhill. When using low beam, the field of view is too small and the field of vision is not good. Clear problems; third, there is no combination of pedestrian detection and reminder technology with intelligent control of car headlights, lack of pedestrian detection and reminder modules at night, and no use of car headlight control systems to warn and warn pedestrians within the dangerous distance on the road. Reminder; Fourth, there is a lack of intelligent lighting options that combine the natural light intensity of the outside world and the light intensity of the car ahead. When there is an approaching car driving ahead, using high beams for a long time will cause the eyes of the driver on the opposite side to be irradiated and unable to see the road ahead. , easily lead to traffic accidents
