ABSTRACT:
In reducing the output from an internal combustion engine by a driving-wheel torque reducing means when a driving wheel is slipping excessively, thereby inhibiting the excessive slipping of the driving wheel, a total torque transmitted from the internal combustion engine to the driving wheel and a surplus torque consumed for the excessive slipping of the driving wheel are found, and the output from the internal combustion engine is reduced on the basis of an effective driving-wheel torque found from the total driving-wheel torque and the surplus torque and transmittable to a road surface. Alternatively, the output from the internal combustion engine may be reduced on the basis of the total torque transmitted from the internal combustion engine to the driving wheel and the surplus torque consumed for the excessive slipping of the driving wheel. Consequently, the driving-wheel torque can be converged quickly to a proper value, and it is possible to provide a closer control of the driving-wheel torque.
