Zusammenfassung:	A sprung vibration estimation unit is configured to calculate a pitch rate of a vehicle body based on the wheel speeds detected by wheel speed sensors. A vibration suppression driving force calculation unit is configured to calculate a vibration suppression driving force for suppressing pitching of the vehicle body based on the pitch rate. An integration unit is configured to calculate a vehicle body speed based on a driver required driving force. A second sprung vibration estimation unit is configured to calculate a pitch rate of the vehicle body (vehicle body speed pitch rate) generated by a change in the vehicle body speed. A determination unit is configured to output a cutoff command for the vibration suppression driving force to an adjustment unit when the vehicle body speed pitch rate is more than a threshold.
