ABSTRACT:
A target torque is calculated as a proportion PI relative to a torque generated by an engine at a basic ignition timing. An ignition timing correction amount is calculated based on this proportion PI, and by correcting the ignition timing by this correction amount, an ignition timing correction which precisely matches a torque-down request is performed rapidly and accurately.
