A controlling method and system based on the automotive lighting system illumination angle synchronizing with the automotive speed

The present invention discloses a controlling method and its application system based on the lighting system illumination angle of the automobile synchronizing with the automotive speed. The said method comprises the following steps: turn on the synchronizing function that makes the automotive lighting system illumination angle (110, 130) change with the automotive speed, after receiving the user's instructions; read and obtain the current automotive speed, look up the prestored correspondence relationship table of lighting system illumination angle synchronizing with each speed grade, find out the specific synchronous angle according to current speed grade under current driving condition; then control the lighting system switching to the found specific illumination angle synchronizing with current speed grade, and achieve the synchronization of illumination angles and automotive speeds. Through applying the method and the application system stated in the present invention, the best illumination effects for an automobile can be achieved,. Therefore, the present invention provides a safer lighting system with a better visual effect, which provides conveniences to users.
