<P>PROBLEM TO BE SOLVED: To sufficiently secure opportunities for learning operation quantity in an engine electronic control device having opportunities to increase a target speed of idling speed. <P>SOLUTION: An engine ECU 50 learns a base duty ratio command value of an actuator 22a driving a throttle valve 22 which is an engine operation quantity as one of conditions where the idling target speed enters a predetermined rotation speed zone during idling operation. If learning is incomplete, idling target speed increase request is rejected and change of the idling target speed is prohibited even if an air conditioner ECU 90 issues the idling target speed increase request. Since change of the idling target speed is prohibited when learning of engine operation quantity is incomplete, a situation that the idling target speed is changed and gets out of a predetermined rotation speed zone and a learning start condition is not established can be avoided. Consequently, opportunities to learn engine operation quantity is sufficiently secured. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
