PROBLEM TO BE SOLVED: To enable deceleration braking by using braking force which is not smaller than that of engine brake generated by regenerative braking of a running motor, even if the hydraulic brake malfunctions. SOLUTION: If a malfunctioning of the hydraulic brake is detected by a brake controller 22, from the output signals of a stop lamp switch SL being a brake sensor, and a hydraulic pressure sensor PS for the hydraulic brake, control is performed by a VCU 24 so that the running motor operates as a generator, and regenerative energy which makes its braking force which is not smaller than that of engine brake is generated. Regenerative braking by the running motor is performed, so that the car is stopped by the decelerating force larger than that of the engine brake. |
