Abstract

가변 용량형 콤프레서를 이용한 경우 등에 FICD 밸브에 의한 보조 공기 유량이 과잉됨에 따른 아이들 회전수의 상승을 방지한다.In the case of using a variable displacement compressor or the like, an increase in idle rotational speed due to excessive auxiliary air flow rate by the FICD valve is prevented.

아이들 운전시에는 AAC 밸브의 피드백 제어에 의해 아이들 회전수가 제어되고 (스텝3), 또한 에어콘용 콤프레서가 적동하고 있으면, 원칙적으로 FICD 밸브(17)가 ON 작동한다(스텝9). FICD 밸브의 고정적인 보조 공기 유량에 대하여 실제의 외부 부하가 적은 경우에는 실제 회전수(Ne)가 과도하게 상승하기 때문에, 판정치이상의 상태가 10초이상 계속되면(스텝4), FICD 밸브(17)를 OFF로 한다(스텝7,10). 마찬가지로, AAC 밸브에 대한 피드백 제어값이 소정 시간 이상 10% 이하고 되었을 경우에도(스텝5), FICD 밸브를 OFF로 한다.During idling operation, if the idling speed is controlled by the feedback control of the AAC valve (step 3), and the air conditioner compressor is activated, the FICD valve 17 is ON in principle (step 9). Since the actual rotation speed Ne rises excessively when the actual external load is small with respect to the fixed auxiliary air flow rate of the FICD valve, if the state beyond the judgment value is continued for 10 seconds or more (step 4), the FICD valve 17 ) To OFF (steps 7, 10). Similarly, even when the feedback control value for the AAC valve is 10% or less for a predetermined time (step 5), the FICD valve is turned OFF.
