Abstract

The invention discloses a device and method for detecting exterior rearview mirrors of vehicles. The device comprises a controller and a microphone module, wherein the controller sends an action instruction to a detected exterior rearview mirror so as to drive the detected exterior rearview mirror to act; when the detected exterior rearview mirror acts, the microphone module obtains a sound signalduring the action of the detected exterior rearview mirror and sends the sound signal to the controller; the controller compares the sound signal with a pre-obtained reference sound signal; if the sound signal is matched with the reference sound signal, the detected exterior rearview mirror works normally; and if the sound signal is not matched with the reference sound signal, the detected exterior rearview mirror is abnormal, so that the working state of the exterior rearview mirror can be detected timely, users can be timely reminded to carry out overhauling before the detected exterior rearview mirror has faults, and then the driving safety and user experience are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle detection, in particular to a device and method for detecting vehicle exterior rearview mirrors. Background technique [0002] With the rapid development of automobile technology, users have higher and higher requirements for the convenience of modern automobiles, and electric exterior mirrors have increasingly become a common configuration of automobiles. The exterior rearview mirror of the vehicle is located on both sides of the vehicle, which helps the driver to observe the situation behind and on both sides of the vehicle, and plays a very important role in the safe driving and parking of the driver. [0003] The driver can adjust the angle of the rearview mirror through buttons in the car to obtain a good rear view. However, after the vehicle has been driven for a period of time, the exterior rearview mirror may become inoperable, affecting the driving or parking of the driver and causing in...
