Controller, vehicle and control method and system used for driving rearview mirrors of vehicle to move

Abstract

The invention belongs to the technical field of vehicles, particularly provides a controller, a vehicle and a control method and system used for driving rearview mirrors of the vehicle to move and aims at solving the problem that existing vehicle outside rear-view mirrors are not completely folded/unfolded at different temperatures on the basis of the same drive time. The control method used for driving the outside rearview mirrors to move includes the steps that the temperature of the environment where the rearview mirrors are located is obtained; according to the temperature of the environment, operation parameters of drive motors used for driving the rearview mirrors to move are determined; and the drive motors operate on the basis of the determined operation parameters. Through the arrangement, the operation time of the drive motors is flexibly adjusted at the corresponding environment temperature, the outside rearview mirrors of the vehicle are fully folded/unfolded, the operationtime of the drive motors is reasonably controlled, and therefore the maintenance period of the drive motors is prolonged.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and specifically provides a controller, a vehicle, and a control method and system for driving the movement of the rearview mirror thereof. Background technique [0002] The rearview mirror is a tool for the driver to directly obtain external information such as the rear, side and below of the vehicle while sitting in the cab seat. In order to facilitate the operation of the driver, prevent the occurrence of driving safety accidents, and ensure personal safety, all countries stipulate that rear-view mirrors must be installed on vehicles, and all rear-view mirrors must be able to adjust the direction. Rearview mirrors are divided into inner rearview mirrors and outer rearview mirrors. Since the outer rearview mirrors are outside the body, they often need to be folded and unfolded to adapt to different driving environments and spaces. [0003] At present, the folding and unfolding of the exterior...

AI Technical Summary

Problems solved by technology

At different temperatures, especially at low temperatures, the motor needs a long driving time to fold / unfold the rearview mirror in place, so the driving time calibrated at normal temperature is not suitable for low temperature

If the driving time value is calibrated according to the low temperature environment, then at normal temperature, if there is no stall current detection, the motor will stall and the current will rise rapidly when the rearview mirror has reached the unfolded or folded position and continues to supply power to the motor. High, may cause the motor to burn out, thereby affecting the life cycle of the motor
