PURPOSE:To quickly cease wheel slip when slip is generated an decrease of driving torque is performed by correcting vehicle speed increasing direction against a vehicle speed corresponding quantity, or correcting throttle opening decreasing direction. CONSTITUTION:Respective wheel speed sensors 11-14 are provided for detecting wheel speed of right and left of front and rear wheels, and theses output signals are input to a traction controller 15. A transmission 43 is controlled to be shifted according to a vehicle speed corresponding quantity varying corresponding to a vehicle speed and a throttle opening corresponding quantity varying corresponding to a throttle opening. When wheel slip is detected based on the wheel speed, traction control to decrease driving torque transmitted to the wheels is performed, by controlling engine output or controlling brake. In this case, at detecting slip, the vehicle speed corresponding quantity is corrected in the vehicle speed increasing direction, or the throttle opening corresponding quantity is corrected in the throttle opening decreasing direction. |
