Abstract

The invention relates to a vehicle lamp follow-up control method based on the steering wheel angle and the vehicle roll angle. A vehicle lamp follow-up control device is provided. The vehicle lamp follow-up control device comprises an ECU control unit, a steering wheel angle sensor, a vehicle roll angle sensor, an AD conversion circuit, a steering gear and a headlamp execution mechanism. The ECU control unit controls the steering gear to rotate according to acquired steering wheel angle information and vehicle roll angle information. The steering gear is connected with the headlamp execution mechanism. The headlamp execution mechanism is connected with headlamps. The vehicle lamp follow-up control device controls the light irradiation direction of the headlamps through rotation of the steering gear. Vision blind zones of drivers during running along curves are eliminated. The driving vision field of the drivers is expanded. The traffic safety is remarkably improved. The probability of accident occurrence is reduced.

Description

technical field

[0001] The invention relates to the technical field of automobile auxiliary driving, in particular to a vehicle light follow-up control method based on steering wheel angle and vehicle body roll angle. Background technique

[0002] When driving at night, because the housing of the lamp is fixed on the car body without steering function, the irradiation direction of the headlight is consistent with the car body. When a car is turning, especially on an urban road without street lights at night, it will affect the driver's judgment on pedestrians or other obstacles on the curve, resulting in traffic accidents and loss of life and property. Therefore, it is very necessary to find a method that can make the beam irradiation direction of the vehicle headlights consistent with the driving direction of the vehicle, eliminate the blind spots of driving vision and significantly improve driving safety.
