PURPOSE:To prevent deterioration in the driving performance of a vehicle due to traveling in a hunting condition by providing a means of operating the slip ratio between a tire and a road face and a driving force controlling means for regulating the feeding quantity of fuel to an engine in accordance with said slip ratio. CONSTITUTION:A driving wheel rotating speed signal DVf from a rear wheel rotating speed detector 10 and non-driving wheel rotating speed signals DVfr, DVfl from front wheel rotating speed detectors 13, 14 are inputted into the F/V converter 6 of a controlling device 3. A microcomputer 4 operates the slip ratio between a tire and a road face and regulates the feeding quantity of fuel to an engine in accordance with the magnitude of the slip ratio. Thereby, the repetition of the reduction and recovery of driving force can be prevented, improving driving performance.
