<p>Driving and driven wheel velocities of a vehicle are detected by wheel velocity sensors (11 - 14), and a change in driven wheel velocities as a function of time is detected to obtain a driven wheel acceleration by the vehicle acceleration calculating section (47). A reference target torque (TG) is calculated on the basis of the driven wheel acceleration. A slip value of the driving wheels is calculated on the basis of the driving and driven wheel velocities, and a correction torque corresponding to the slip value is calculated every predetermined sampling time at TSn calculating section (55) and TPn calculating section (56). The correction torque is subtracted from the reference target torque to obtain a target engine torque (TG). An engine output is controlled to obtain the target engine torque.</p>
