A kind of automobile rearview mirror and control method

Abstract

The invention discloses a car rearview mirror and a control method. The car rearview mirror at least comprises a left-right drive motor, a pair of transverse control arms, a pair of vertical drive motors, two pairs of longitudinal control arms, two pairs of fixed fulcrums and a flexible glass sheet. The two pairs of fixed fulcrums are correspondingly arranged on the two pairs of longitudinal control arms. The flexible glass sheet is fixedly mounted on the two pairs of fixed fulcrums. Each pair of longitudinal control arms is connected to one transverse control arm; the left-right drive motor drives the transverse control arms to bend and stretch in the transverse direction and drives the flexible glass sheet to bend in the left-right direction; the vertical drive motors control the longitudinal control arms to bend and stretch in the longitudinal direction and drive the flexible glass sheet to bend in the vertical direction, and therefore the view field range is expanded.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile rearview mirror and a control method. Background technique [0002] At present, the rearview mirror of a car is flat, the viewing angle is not large, and there is a certain blind spot in the field of vision. When the driver is driving the vehicle, he often confirms the road conditions by changing the angle of the rearview mirror. However, the current electric rearview mirror control device is generally installed near the door handle. When the angle of the rearview mirror is adjusted according to the situation, the driver cannot flexibly grasp the field of vision of the rearview mirror, resulting in a blind spot of the rearview mirror, which will affect driving safety to a certain extent. [0003] In the prior art, in order to overcome the blind spot of the rearview mirror, it is usually necessary to install a spherical mirror on the exterior rearview mirror or ...

AI Technical Summary

Problems solved by technology

The lack of field of view is compensated by installing additional lenses such as convex mirrors, spherical mirrors or prisms on the original mirror surface of the exterior rearview mirror. The disadvantage is that the additional lenses will seriously deform the observation scene, and the convex mirrors, spherical mirrors or prisms cannot be flexible. Adjust to cope with the complex road conditions during driving, and the small mirror surface of the additional lens makes it difficult to observe, and also makes the usable area of ​​the original lens smaller, which affects normal use, and the additional lens is easy to fall off

Blind spot detection technology is used to detect whether there is a vehicle in the blind area of ​​vision, but when the vehicle is driving in a tunnel or close to the wall, the system will mistakenly believe that there is a car and issue a false alarm

[0004] Therefore, how to solve the problem in the prior art that the rearview mirror cannot flexibly adjust its position during driving and cause blind spots is a problem that is generally concerned by those skilled in the art.
