PURPOSE:To reduce the exhaust quantity of uncombusted fuel by controlling the air fuel ratio of the mixed gas to a proper valve by making the correction value of for the fuel quantity corresponding to the engine operation state ineffective, when the slip state lower than the excessive slip state of a driving wheel is detected. CONSTITUTION:A vehicle 1 is set, for example, into front wheel drive type, and speed sensors 21-24 are installed individually onto the right and left driving wheels 11 and 12 and the right and left trailing wheels 13 and 14. Each detection signal supplied from the speed sensors 21-24 is calculation-processed in an ECU 35, and a plurality of fuel injection valves 36 of an engine 31 are controlled according to the result, and the excessive slip state of each driving wheel 13, 14 is controlled. In this device, if the slip state lower than the excessive slip state of each drive wheel 13, 14 is detected, the correction valve for correcting the fuel quantity jetted from each fuel injection valve 36 according to the engine operation state is made ineffective.
