PURPOSE:To effectively use the driving force from an engine at the time of low speed traveling by controlling the slippage of the driving wheel which indicates the lower speed of detected right and left driving wheels when the speed of vehicle is lower than a defined speed. 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 at the time of the accelerating operation of the vehicle 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, vehicle speed is detected based on the speeds of the right and left driven wheels 13, 14 and, when the vehicle speed is lower than a defined speed, the slippage of the driving wheel 11 or 12 which indicates the lower speed of the right and left driving wheels 11, 12 is controlled. Thereby, the driving force of an engine at the time of low speed traveling can be effectively used. |
