ABSTRACT:
In a driving force control apparatus, a target driving torque To is obtained based on a value determined by subtracting a feedback correction torque T.sub.F corresponding to a slip amount DVS from a correction reference torque T.sub.BC corresponding to a vehicle body speed V.sub.B. Slip is suppressed by a throttle control so that the engine output is reduced to the target driving torque T.sub.O. A retard command is output when the slip amount DVS and a slip rate GDVS are greater than predetermined values to retard an ignition timing of the engine, thereby suppressing an abrupt slip. When it is determined that a right and left front wheel speed difference is large and the vehicle is running on a split road, a retard command is made difficult to be reset as compared to a case where the vehicle is not running on a split road. When it is detected that the driving wheels are vibrating, particularly a differential factor is decreased and regulated only to a component to reduce the target driving torque. With the driving force control apparatus, when a slip occurs, the engine output is reduced to prevent vehicle body vibration during operation of a device to suppress a slip.
