Multifunctional intelligent integrated headlamp control system and method

Abstract

The invention belongs to the technical field of vehicle lamp light and provides a multifunctional intelligent integrated headlamp control system and method. The multifunctional intelligent integrated headlamp control system comprises a data acquisition unit, a control unit and an execution unit. Vehicle lamps are automatically adjusted during driving at night, blind areas during two-vehicle meeting, turning or upward climbing or downward climbing, the vehicle lamps are automatically adjusted according to the weather situation to improve the driving safety. The vehicle lamps include a dipped headlamp, turning light supplementing lamps, ramp light supplementing lamps and a fog lamp. The turning light supplementing lamps include a turning light supplementing lamp A and a turning light supplementing lamp B which are respectively arranged on two sides of the dipped headlamp in the horizontal direction. The ramp light supplementing lamps include a ramp light supplementing lamp C and a ramp light supplementing lamp D which are respectively arranged on two sides of the dipped headlamp in the vertical direction. In addition, a direct current motor and other mechanical drive structures are omitted, response time is shortened, the reliability of the system is improved, and production and maintenance costs are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle lights, in particular to a multifunctional intelligent integrated headlight control system and method. Background technique [0002] Vehicles running at night in most cities generally use low beams for lighting, but there are still some drivers who turn on high beams. When the two vehicles meet, the other driver's sight is blocked, which is extremely prone to traffic accidents. The existing lighting system generally only has a fixed irradiation range. When the vehicle is turning at night, the fixed headlights cannot illuminate the inner side of the curve, and blind spots often appear, seriously affecting the safety of driving at night. Similarly, when going up and down a large ramp at night, due to the fixed range of illumination of the lights, blind spots will also be generated, resulting in safety problems.

Problems solved by technology

[0002] Vehicles driving at night in most cities generally use low beams for lighting, but there are still some drivers who turn on high beams. When the two vehicles meet, the sight of the other driver is blocked, which is extremely prone to traffic accidents

The existing lighting system generally only has a fixed irradiation range. When the vehicle is turning at night, the fixed headlights cannot illuminate the inner side of the curve, and blind spots often appear, which seriously affects the safety of driving at night.

Similarly, when going up and down a large slope at night, due to the fixed range of illumination of the lights, blind spots will also be generated, resulting in safety problems

And existing AFS (Adaptive Front Lighting System) adopts mechanical transmission structure, speed sensor and steering wheel angle sensor on hardware, controls the horizontal rotation of automobile headlight by the transmission structure of worm gear plus DC motor, Due to the complex mechanical transmission structure and low reliability, the control accuracy of the DC motor as the driving motor is low, and the response speed of the system is slow. At the same time, when the vehicle is turning, the headlights may even vibrate, which affects the actual lighting effect.
