ABSTRACT:
For an internal combustion engine with a supercharger, a slip of the driven wheel is controlled by reducing torque of the engine, when the extent of the slip becomes large in relation to a road surface. When the running status of the engine exists in a non-supercharging region, the slip is controlled by at least one of operations for reducing the amount of fuel to be supplied to the engine and for retarding the timing of ignition (first slip control). On the other hand, in a supercharging region, the slip is controlled by lowering the pressure to be supercharged (second slip control). In a transient period of time when the running status of the engine is caused to shift from the non-supercharging region to the supercharging region when the first slip control is being conducted in the non-supercharging region, the first slip control is allowed to be continued until the slip is caused to be converged, in place of the second slip control.
