Method and system for automatically folding exterior rearview mirror

Abstract

The invention discloses a method and a system for automatically folding an exterior rearview mirror. The method includes steps of 110, detecting the running speed of a vehicle and judging whether the running speed is smaller than or equal to a first speed preset value or not; 120, detecting whether an obstacle is positioned in the advancing direction of the exterior rearview mirror or not when the running speed is smaller than or equal to the first speed preset value; 130, folding the exterior rearview mirror if the obstacle is positioned in the advancing direction of the exterior rearview mirror; 140, continuing detecting whether another obstacle is positioned in the advancing direction of the exterior rearview mirror or not; 150, unfolding the exterior rearview mirror under the condition that the obstacles are not positioned in the advancing direction of the exterior rearview mirror. The method and the system have the advantages that whether the obstacles are positioned in the advancing direction of the exterior rearview mirror or not is detected, so that the exterior rearview mirror can be automatically unfolded or folded under the control, pressure on a driver is relieved, the driver does not need to manually control unfolding and folding of the exterior rearview mirror, the driving safety is improved, and the exterior rearview mirror is protected; the vehicle can easily run through a narrow and small place after the exterior rearview mirror is folded, and the exterior rearview mirror is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of exterior rearview mirrors for vehicles, in particular to an automatic folding method for exterior rearview mirrors and an automatic folding system for exterior rearview mirrors. Background technique [0002] The exterior rearview mirror is an important part of the vehicle. Its function is to enable the driver to clearly observe the movement of the vehicle coming from behind to improve driving safety. However, the exterior rearview mirror increases the width of the vehicle and reduces the passing performance. In the actual use of the car, the exterior rearview mirror is often scratched or even damaged due to collisions, which sometimes has a certain impact on the safety of pedestrians. [0003] Therefore there is following deficiency: exterior rearview mirror has increased the width of vehicle, and for narrow place, because of the reason of exterior rearview mirror, vehicle can not pass through, if vehicl...
