At the motor ABS control unit 300, a wheel slip ratio s (i.e., a ratio of the wheel speed to the vehicle speed) is calculated based on the estimated vehicle speed and the drive wheel average wheel speed, and a second regeneration torque command value calculated based on the torque of the
first regeneration torque command.

case in which a sudden change occurs from a low p road to a high p road is described. For a low up road, a slip state occurs with only the regeneration torque, and deceleration is fairly small. Therefore, motor ABS control and brake ABS control are used together.

the motor ABS control unit 300 (motor slip suppression control unit) configured to reduce a torque absolute value of the electric motor 1 so that the slip ratio of each of the drive wheels is the target motor slip ratio Sm;

a slip suppression control unit configured to, during braking, calculate a first slip ratio, which is a slip ratio of the drive wheels based on the calculated vehicle speed and an average value of the detected wheel speeds of the drive wheels, and when the first slip ratio is equal to or larger than a predetermined value, suppress the slip state so that the slip ratio of the drive wheels is a first target slip ratio for a motor ABS,
