PURPOSE:To always carry out a proper slip control by detecting the excessive slip of one driving wheel of right and left driving wheels in accordance with the speed of the driven wheel on the same side as said driving wheel of right and left driven wheels and restricting the slip of said driving wheel. CONSTITUTION:The output signals of speed sensors 21-24 for detecting the speeds of right and left driving wheels 11, 12 and right and left driven wheels 13, 14 at the time of operating a vehicle are taken in an ECU35. In this ECU35, the excessive slip of the right and left driving wheels 11, 12 is detected based on the speed of the right and left driven wheels and, when excessive slip is detected, a fuel injection valve 36 is controlled to restrict the slippage of the driving wheels 11, 12. In this case, the detection of one driving wheel 11 or 12 is carried out based on the speed of the driven wheel 13 or 14 on the same side as the driving wheel. Thereby, apparent slippage when a vehicle is turning can be reduced and a slip ratio can be more accurately detected, enabling proper slip control at all times. |
