내용없음 An automotive electronic control device includes an electronic control unit 6 for controlling an automotive alternator 2 and the ISCV (Idling Speed Control Valve) 8 of the engine. To improve the mileage of the automobile, the duty factor of the alternator 2 is reduced to zero when the electric load is a light load. Further, when the increase in the load current IL during the idling is above a load current threshold increment level DELTA LT, the ISCV (Idling Speed Control Valve) 8 is controlled to increase the air intake, and, simultaneously, the duty factor of the alternator 2 is reduced to a low level for a predetermined length of time equal to the response time in which the rpm of the engine responds to the increase of the air intake effected by means of the ISCV (Idling Speed Control Valve) 8. The duty factor of the alternator 2 is gradually increased thereafter. The idling rpm of the engine can thus be stably controlled when a heavy electric load is turned on.
