Abstract
A control apparatus for an internal combustion engine which is mounted in a vehicle and has a supercharger that is located along an intake passage of the internal combustion engine and driven by a motor, includes a controller which drives the motor to perform supercharging during warm-up of the internal combustion engine, and supercharges a plurality of times intake air to be supplied to the internal combustion engine. Accordingly, the intake air is supercharged a plurality of times during warm-up of the internal combustion engine, so the temperature of the intake air is raised sufficiently to warm up the engine, thus enabling the engine to be warmed up effectively.
