Abstract

The invention discloses an automatic control method and an automatic control system for an exterior rearview mirror of an automobile, and belongs to the field of automatic control. In the method and the system, the exterior rearview mirror is adjusted by comparing a linear distance between the exterior rearview mirror and the nearest road edge or object edge with a preset minimum distance; and the method and the system improve the traffic ability and the driving safety of the automobile, improve pedestrian protecting function of the vehicle, effectively avoid accidents that the vehicle bumps or hurts pedestrians caused by insufficient space on the lateral part of the vehicle, and have the advantages of convenient use and high driving safety. The invention provides another method and another system; that whether the automobile is in a parked state is judged by receiving signals; and the exterior rearview mirror is automatically folded or unfolded on the basis; therefore, the mirror surface can be protected, the automobile parking space can be reduced, and the scratching is effectively avoided; meanwhile, when the automobile is started, the exterior rearview mirror is automatically unfolded, and favorable guarantee is provided for safe driving.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to an automatic control method and system for an automobile exterior rearview mirror. Background technique [0002] The most important and basic function of the exterior rearview mirror of a car is to provide the driver with a view on both sides of the vehicle body. At present, the general model will be equipped with an exterior rearview mirror on the left and right sides of the body. [0003] Vehicles will inevitably encounter narrow roads or scratches with pedestrians during driving. As the widest part installed on the vehicle, the exterior rearview mirror is the easiest to contact with other objects or pedestrians. Therefore, the exterior rearview mirror needs to have Automatic folding function and reset function to ensure the safety of driving. In addition, when parking on the side of the road in a metropolis, the folding function of the exterior rearview mirror is also partic...
