PROBLEM TO BE SOLVED: To efficiently restrict the slippage of wheels, while efficiently controlling a motor and an engine by computing a slip value of the wheels, and when the slip value exceeds the predetermined threshold value, controlling the output torque of the motor and the engine so that the slip value is converged to a target value. SOLUTION: During the operation of a vehicle, an ECU 100 drives the vehicle for traveling with the drive force of a motor 2 in a low area of the required torque, and with the drive force of an engine 1 and the motor 2 in a middle area of the required torque, and with the drive force of the engine 1 in a high area of the required torque. Slip ratio SL of each wheel 11-14 and change ratio ΔSL thereof are computed, and when the change ratio ΔSL exceeds the prescribed threshold, the output torque of the motor 2 and the engine 1 is controlled so that the slip value is converged to a target value. Namely, when the change ratio ΔSL is reduced after the slip ratio SL is suddenly increased, output torque of the engine 1 is increased. |
