A method and system for controlling flipping of a rearview mirror

Abstract

The invention discloses a method and system for controlling rearview mirrors to reverse. The method for controlling the rearview mirrors to reverse comprises the steps that firstly, peripheral environment images of a motor vehicle are obtained, and the peripheral environment images are subjected to road condition element marking so as to mark road condition elements in the images; then, the road condition elements existing in a preset range of vehicle backing trajectories in the element-marked images are classified, when higher first kind of road condition elements exist in the preset range ofthe vehicle backing trajectories, rearview mirrors of the motor vehicle are controlled to reverse a small angle towards the ground surface, so that a driver can observe higher first kind of road condition elements from the reversed rearview mirrors; when only shorter second kind of road condition elements exist in the preset range of the vehicle backing trajectories, the rearview mirrors of the motor vehicle are controlled to reverse a large angle towards the ground surface, so that the driver can observe the shorter second kind of road condition elements from the reversed rearview mirrors, and thus the applicability of automatic reversing angles of the rearview mirrors under the working condition of vehicle backing is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, and more specifically, to a method and system for controlling flipping of rearview mirrors. Background technique [0002] With the continuous development of vehicle engineering technology, motor vehicles have added many comfort functions and driving assistance functions on the basis of the original driving functions. [0003] Taking the reversing condition of a motor vehicle as an example, in some motor vehicles today, when the driver puts the driving gear of the motor vehicle into the reverse gear (or R gear), the controller of the motor vehicle will automatically flip the rear view When the mirror switch is turned on, the rearview mirror far away from the driver's side will be automatically flipped to the ground at a certain angle, so that the driver can learn the road conditions away from the driver's side from the flipped rearview mirror, so as to avoid The tires or wheels of the...

AI Technical Summary

Problems solved by technology

[0004] However, in these motor vehicles, the angle at which the rearview mirror is turned downward is a fixed angle. When the driving scene of the motor vehicle changes, the driver still needs to manually adjust it to observe from the rearview mirror on the side away from the driver. to the area of ​​interest or road surface elements, which greatly reduces the applicability of the function of automatic flipping of the rearview mirror in the prior art
