Abstract

A method for controlling the vehicle lighting system viewing angles synchronizing with the turning angles and system thereof, comprising: obtaining a current vehicle turning angle signal, transforming it into current turning angle value; finding out the specific lighting system illumination angle synchronizing with a turning angle range according to the value; then controlling the lighting system switching to the found specific synchronizing illumination angle, achieving synchronization between viewing angles and turning angles. Through synchronizing with turning angles, the system automatically controls the lighting system spotlight degrees, thus controls the illumination angles, and brings a wide range visual effect to drivers. Without driver'"'"'s extra operations, the system can automatically adjust the lighting system illumination angles according to different turning angles, thus adjust the driver'"'"'s viewing angle sizes, further improves the driving safety.
