Abstract
An engine output controlling system for a vehicle by which a driving torque produced by the engine is utilized effectively and such a possible slip of a driving wheel the vehicle that makes driving of the vehicle difficult. The system detects a slipping condition of the driving wheel, sets an aimed driving torque of the engine in accordance with the slipping condition thus detected, and controls the engine to generate the aimed driving torque thus set and controls the engine to retard the ignition timing thereof when the detected slipping condition is excessively great. The system obtains a slip changing rate of the driving wheel, and sets a retard amount, with which the ignition timing is to be retarded, in accordance with the slip changing rate detected.
