When a diagnosis result of an ABS control system is normal, a determination is made as to whether or not to execute ABS control based on a slip ratio of a vehicle wheel, whereupon motor torque control is executed based on an operational state of an ABS. In other words, when ABS control is not executed, the motor-generator is controlled to a regenerative state, and when ABS control is executed, the motor-generator is controlled to a power running state. When the diagnosis result of the ABS control system is abnormal, on the other hand, regenerative braking by the motor-generator is prohibited immediately and the motor-generator is controlled to the power running state.
