Abstract

The invention discloses a vehicle and a method and device for controlling discharge of a motor of the vehicle. The method includes the steps that a vehicle power-off instruction is detected, and it isdetermined that the vehicle power-off instruction is received; the motor is controlled to get into an active discharge mode; the current counter electromotive force of the motor is acquired; the motor is controlled to be actively discharged according to the counter electromotive force. By means of the method, the problem of whole vehicle shake caused by motor discharge can be effectively eliminated.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and device for controlling discharge of a vehicle and its motor. Background technique [0002] In the related art, in order to avoid personal injury caused by the high voltage in the motor of the electric vehicle, it is necessary to discharge the high voltage in the motor of the electric vehicle when the electric vehicle is powered off. However, in the process of controlling the motor to discharge, the whole vehicle often shakes, which affects the driving experience. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, the first object of the present invention is to provide a motor discharge control method of a vehicle, which can effectively eliminate the vibration problem of the whole vehicle caused by the motor discharge. [0005] The second object ...
