Abstract
The present invention relates to an electronically driven pressure boosting system that is used to boost the torque output of an Internal combustion engine. Engine operating parameters are fed to an engine control unit (ECU) controlling a supercharger that boosts engine torque. The ECU monitors at least one of the engine operating parameters and calculates the likelihood that the engine torque needs to be boosted by the supercharger. When the supercharger is operating at an idle speed, the ECU controls the idle speed so that a lag time varies inversely with the calculated likelihood that the supercharger needs to boost engine torque.
