Abstract
The procedure of slip detection computes a right wheel speed Vr from a rotation speed Nmof a motor MGdetermined according to a detection result of a rotational position detection sensorand from a left wheel speed Vl measured by a wheel speed sensorattached to a left wheel. A right wheel acceleration ar is calculated from the computed right wheel speed Vr. When the calculated right wheel acceleration ar exceeds a preset reference value arslip, the procedure detects the occurrence of a slip of a right wheel. When a left wheel acceleration al calculated from the obtained left wheel speed Vl exceeds a preset reference value alslip, the procedure detects the occurrence of a slip of the left wheel.
