ABSTRACT:
Detection of engine idling is preformed by detecting the position of a throttle valve corresponding to idling and discriminating an intake air flow rate in a range of idle air flow rate. A signal indicative of engine idling is produced when both the throttle valve is in idling position and the air flow rate is less than the idle air flow rate.
