Zusammenfassung:	PURPOSE:To prevent a shift hunting by using a car speed at a point of time of a car wheel speed change from deceleration to acceleration during traction control, as a speed change decision factor until next car wheel speed change from deceleration to acceleration is detected. CONSTITUTION:A traction controller (c) conducts an output control of an engine (b) according to a drive wheel speed and an actual car speed. Even in the case of this operation being decided by means of a decision means (d), a point of time when a car wheel speed is changed from deceleration to acceleration is detected by means of a car wheel speed detection means (e), and the car speed at this time is used as a speed change decision factor at a speed change control means (f) until next car wheel speed change from deceleration to acceleration is detected, and the speed change control of an automatic transmission (a) is conducted. Thus, the prevention of a shift hunting and the reduction of a speed change shock can be realized as the car speed at the carwheel speed change time point which is used as the speed change decision factor is obtained as a specified false car speed approximate to the actual car speed, and also increased and decreased at the car wheel speed change time.
