A slip control system includes a supercharging pressure control valve for controlling a supercharging pressure produced by a supercharger, a rotation speed detector for detecting a rotation speed of a drive wheel, a slip detector for detecting a slip amount of the drive wheel based on the rotation speed of the drive wheel, a supercharging condition detector for detecting a supercharging condition and a non-supercharging condition, and an engine output restrictor for restricting an engine output by utilizing at least one of the supercharging pressure control device and an engine control valve to reduce the slip amount of the drive wheel when the slip amount of the drive wheel exceeds a predetermined threshold value. The engine output restrictor controls the supercharging pressure by the supercharging pressure control valve in the supercharging condition when the slip amount of the drive wheel exceeds the predetermined threshold value. Further, the engine output restrictor controls the engine output with the engine control device in the non-supercharging condition when the slip amount of the drive wheel exceeds the predetermined threshold value. In the supercharging condition, the engine control, such as a retard control of the ignition timing and a fuel cut control, is restricted so that an undesirable increase in the catalyst temperature can be prevented.
