| description | The invention discloses a motor electric braking control method and device for an electrically driven vehicle, and the method comprises the steps: S1, when a vehicle enters a braking working condition, controlling and adjusting the braking torque of a motor according to a torque mode which takes the torque as a following control target, so as to reduce the rotating speed of the motor; S2, when the speed of the motor is reduced to a specified switching threshold value, controlling to be switched to a rotating speed mode taking the rotating speed as a following control target, and controlling the rotating speed of the motor to be reduced to zero speed according to the rotating speed mode; and S3, after the rotating speed of the motor is zero and lasts for specified time, switching to a position mode taking the position as a following control target, and controlling the position state of the motor rotor according to the position mode. The method has the advantages of being simple in implementation method, low in |
