Abstract
As slip amounts or amounts of slippage of the driven wheels on pavement get larger, the torques to be applied to the driven wheels are reduced. The slip amounts of the driven wheels are determined on the basis of a vehicle speed and rotational speeds of the driven wheels, and the vehicle speed is determined as a vehicle speed of the vehicle body against pavement at a given reference position of the vehicle body. The torque to be reduced upon slippage of the driven wheels is corrected on the basis of a difference in cornering radius between a cornering radius at the reference position and a cornering radius of the driven wheel.
