ABSTRACT:
An engine output control system for a vehicle detects a degree of slip of driving wheels of the vehicle and determines engine output reduction requirement by which the output of the engine is to be reduced in order to converge the degree of the slip of the driving wheels on a target value according to the degree of slip detected. The output of the engine is reduced by the engine output reduction requirement when the engine speed is not lower than a preset engine speed and reduction of the engine output is inhibited when the engine speed is lower than the preset engine speed. The preset engine speed is changed according to the engine output reduction requirement so that the preset engine speed is higher when the engine output reduction requirement is large than when it is small.
