Title: CONTROL DEVICE FOR ELECTRIC VEHICLE
Abstract:
Provided is a control device for an electric vehicle equipped with drive wheels that are driven via a drive shaft by an electric motor, said control device capable of obtaining an adequate suppression effect with respect to torsional vibration generated in the drive shaft. A first damping control torque for cancelling out a vibration component is calculated on the basis of the difference between the motor rotational speed and the vehicle speed, and a drive torque command value for driving an electric motor is calculated by adding a driver-requested drive torque and the first damping control torque.
