ABSTRACT:
A driving torque adjusting system for adjusting a driving torque acting upon driven wheels, for example, a throttle valve for adjusting an output power or torque from the engine, is subjected to feed-back control at a set response velocity so as for an actual slip value of the driven wheel to reach a given target value. When the actual slip value of the driven wheel is equal to or larger than a set value larger than the target value, only the set response velocity in the direction of reducing the driving torque acting upon the driven wheels is corrected to become larger when the actual slip value is smaller than the set value. Preferably, the set response velocity is set smaller as a friction coefficient on a road surface is smaller in both cases where the torque acting upon the driven wheels is increased and decreased. An amount to correct the set response velocity, i.e., a magnitude of the set response velocity in the direction of reducing the driving torque, when the actual slip value of the driven wheel is equal to or larger than the set value becomes larger as the friction coefficient on the road surface is smaller.
