Abstract: PROBLEM TO BE SOLVED: To suppress shaking of an electric vehicle, and also suppress deterioration of fuel consumption thereof.SOLUTION: When it is not in regenerative cooperation conversion for converting a regenerative torque of a motor into braking force by a hydraulic brake, a damping control-on request is output when a motor speed variation ΔNm is a threshold value Nref or more (S140), and a damping control-off request is output when the motor speed variation ΔNm is less than the threshold value Nref (S150). Alternatively, when it is in regenerative cooperation conversion, the damping control-on request is output regardless as to whether the motor speed variation ΔNm is the threshold value Nref or more (S140). Thereby, shaking of a vehicle due to torque fluctuation of a drive shaft easily occurring in regenerative cooperation conversion can be suppressed, and also the shaking can be quickly reduced even if the shaking occurs. Also, deterioration of fuel consumption can be suppressed in comparison to the type that always performs the damping control.
