Abstract

The embodiment of the invention discloses a method for controlling an electric outside rear-view mirror. By means of the method, the problems that according to an existing control mode for the electric outside rear-view mirror, locked-rotor detection is prone to failure, and control is unstable are solved. The method comprises the steps that a CAN message generated when a car moves is obtained; a motor of the electric outside rear-view mirror is driven according to the CAN message so that the electric outside rear-view mirror can make corresponding actions; and the current of the motor during operating is monitored in real time, and if the current exceeds the preset threshold value, the motor is controlled to stop running. The embodiment of the invention further provides a device for controlling the electric outside rear-view mirror.

Description

technical field [0001] The invention relates to the field of exterior rearview mirror control, in particular to a control method and device for an electric exterior rearview mirror. Background technique [0002] At present, the device that controls the operation of the motor of the rearview mirror of the car is generally controlled by the following methods: [0003] 1. The limit switch monitors the situation of motor stalling. In this case, the space is limited, and the limit position of the motor rotation uses the limit switch to monitor whether the motor rotates in place. The disadvantages are that it takes up a lot of space, the travel switch is fragile, and the service life is low; there are many lead-out wire harnesses, which increases the structural difficulty of the folder. [0004] 2. Hall monitors the position of the motor, and judges the position of the motor through the Hall of the motor, whether it has reached the limit position of rotation; thereby causing the ...
