Abstract
A control unit of the present invention for an electric vehicle capable of being driven using torque from an electric motor generated in response to a torque instruction, comprising an electric motor rotation speed detection and estimation unit for detecting or estimating rotation speed of the electric motor, a drive wheel rotation speed detection and estimation unit for detecting or estimating rotation speed of drive wheels, and a torque instruction compensation unit. The torque instruction compensation unit compensates the torque instruction so as to control vibration of the vehicle based on rotational speed of the electric motor detected or estimated by the electric motor rotation speed detection and estimation unit and drive wheel rotation speed detected or estimated by the drive wheel rotation speed detection and estimation unit.
