By the adoption of the system, the influence factors of ambient light to a driver are integrated, a high beam controller is independent of a vehicle-mounted center control system, manual switching switch signals of steering column headlamps are sent to the high beam controller to serve as safety auxiliary signals, the reliability of a high beam control system is improved, and the intelligent control system for the high beams is suitable for transforming headlamps of various vehicles to be low in cost and high in practicality.

Description

technical field [0001] The invention belongs to the field of vehicle active safety, in particular to a vehicle high beam intelligent control system and a control method. Background technique [0002] Vehicles have become the mainstream means of transportation, and improving driving safety is an important issue that people care about. Existing vehicles require the driver to manually switch between the high and low beams according to the brightness of the road lights and the state of the vehicle ahead, which increases the difficulty and trouble for the driver to control the vehicle, resulting in many drivers not turning off the high beams regardless of the road conditions. Indiscriminate use of high beam lights is very common. It will not only cause blind spots on the front and oncoming vehicles, but also affect the sight of pedestrians, because glare is very annoying, and it is also one of the root causes of many traffic accidents. Based on the frequent occurrence of traffic...

AI Technical Summary

Problems solved by technology

Because photoresistors, phototransistors, photocells and other photosensitive elements cannot correctly judge the actual road conditions, the distribution of various street lights and car lights, and the comprehensive situation of local light intensity, the practicability of the above technology is limited.

[0004] An improved combined light sensing device, such as Chinese patent: CN201320002579.6, although it can measure the light intensity from a specific direction and the influencing factors of ambient light, it is very difficult to measure the curved road conditions and the tail lights of vehicles ahead and intersections. intractable

[0005] The more effective road condition detection method is based on the application of camera technology, such as Chinese patent CN201110318196.5, but because the central control panel of the car is used as a DSP control system, the analysis and processing of the gray threshold value of the pixels in the local area does not consider the environment The influence factors of light on camera measurement results, the influence conditions of driving dynamic road conditions on drivers and the influence factors of taillights of vehicles in front, the versatility, adaptability and economy of the above technologies are limited

[0006] For example, Chinese patent CN200480004699.3 is a vehicle equipment monitoring and control system that uses camera detection. However, due to the complexity of the system, the integrated system of programmable gate array FPGA and digital signal processor DSP is used, and the system does not consider the influence of ambient light. There is no high-beam control scheme for various vehicles, and the entire system is complex, which is difficult to apply to transform the headlights of various vehicles into low-cost and easy-to-use high-beam intelligent control devices
