御装置。[Scope of Claim for Utility Model Registration] The crankshaft of the engine is connected via a continuously variable transmission to a supercharger in the intake system for supercharging, and the continuously variable transmission changes speed according to a speed change signal from a control unit. In a control system that increases/decelerates and controls load on a supercharger, an engine abnormality detection means determines whether or not there is an engine abnormality, a speed change speed calculation means calculates a speed change taking into consideration the effectiveness of the engine brake, and the above-described control system is provided when an engine abnormality occurs. 1. A control device for a supercharged engine, comprising engine output reducing means for immediately shifting a continuously variable transmission to a large gear ratio, and then controlling the gear ratio to a maximum gear ratio according to the shifting speed.
