Description

Automobile outer rear-view mirror turn light control system

Technical Field

The utility model relates to an automobile control technical field especially relates to an automobile exterior mirror indicator system.

Background

With the development of automobiles, warning is always an important function in the driving process, particularly the side warning of the automobile. In the process of driving, steering and backing of the existing vehicle, the head lamp and the tail lamp play a role in safety warning and identification. In a dark environment, for pedestrians, a vehicle body in the middle from the head to the tail of the vehicle belongs to an area which is difficult to recognize. But is limited by complex driving environment, and the light of the head and the tail of the vehicle is far from enough.

At present, the steering lamp of the outer rearview mirror is not completely popularized, and the steering lamp with high warning and recognition degrees is needed for vehicles without the function of the steering lamp on the rearview mirror; for the vehicle with the steering lamp of the rearview mirror, the steering lamp effect of the original vehicle is uniform, the light brightness is low, and the warning effect is greatly discounted. The outer rearview mirror steering lamp needs to have better warning and identifying light, so that driving safety can be better guaranteed.

For the outer rearview mirror steering lamp of the vehicle, only one light display effect is provided, the lamp flashing mode or the water flowing mode is single, and the mode is fixed and can not be switched. If the car owner needs to install, change the lamp effect or repack the back and restore, need carry out the dismouting to the rear-view mirror once more, this action is not only troublesome, probably causes the destruction to the rear-view mirror moreover. If the owner is unfamiliar with the operation, the owner also needs to go to the automobile maintenance point to replace the automobile, and more time and cost are consumed.
