ABSTRACT:
A wheel speed differential with another wheel of each of several wheels is determined as a parameter for brake-adjustment use, and driving torque conveyed respectively from an engine to the several wheels is adjusted by braking torque determined on a basis of the parameter for brake-adjustment use so as to restrain the wheel-speed differential. In such a driving torque control, the engine output is reduced if the braking torque is excessive. Therefore, load to the brake apparatus and drivetrain caused by engine output can be reduced. Thus, deterioration of the durability of the brake apparatus and drivetrain can be prevented.
