Kind Code:
A1
Abstract:
Disclosed is a motor control device for electric vehicles that controls the torque of a motor connected to drive wheels by setting a motor torque command value on the basis of vehicle information, wherein the motor control device comprises: a damping control unit that executes, with respect to the motor torque command value, damping control for suppressing vehicle vibration; a motor torque control unit that controls the motor torque in accordance with the motor torque command value that has been subjected to said damping control; and a parking-lock release determination unit that determines whether or not a parking-locked state, in which the wheels are locked from rotating, is released. When said parking-locked state is released, the damping control unit executes damping control using a control constant calculated from a vehicle model in a wheel-locked state.
