摘要： Provided are a control device for an electric vehicle and a control method for an electric vehicle capable of appropriately suppressing a vibration. In the control device for an electric vehicle according to the present invention, when a torque is controlled that is generated by a motor configured to generate a torque for braking or driving a drive wheel via a speed reduction mechanism and a drive shaft coupled to the speed reduction mechanism, the torque generated by the motor is controlled based on a rotational torque command value based on an accelerator operation or a brake operation by a driver, and a vibration suppression control torque command value for suppressing a vibration component caused by a resonance of the vehicle. Then, when a predetermined condition is satisfied, the torque generated by the motor is reduced.

摘要： Provided is a driving force control device capable of stabilizing a vehicle behavior when a driving torque of a drive wheel is controlled. When slip suppression control is carried out to decrease a driving torque of a drive source that is connected to the drive wheel of a vehicle via a speed reduction mechanism and a drive shaft, and is configured to generate a torque for braking or driving the drive wheel, to thereby suppress a slip state of the drive wheel, the driving torque of the drive source is controlled so that a slip ratio of the drive wheel is in an area of the slip ratio smaller than a slip ratio corresponding to a peak value of a road surface friction coefficient in a characteristic of the road surface friction coefficient with respect to the slip ratio.
