Abstract
An operation control system for an internal combustion engine includes a first current detector for detecting a value of electric current flowing in a field winding of an AC generator of the engine, and an ECU responsive to the detected value of electric current for determining a control amount by which the operation of the engine is to be controlled, and for changing output torque of the engine in response to the determined control amount. A second current detector, preferably, a Hall element, detects a value of electric current flowing from the AC generator to electrical loads on the engine. The ECU detects a transient state of the electrical loads, based upon the detected value of electric current from the second current detector. The ECU is operable when the transient state is detected, for determining a transient correction amount of the determined control amount, in response to the detected value of electric current from the first current detector.
