Abstract

본 발명은 차량의 에어콘 작동중 엔진회전수가 높을 때 압축기에 무리하게 걸리는 부하에 따라 고장되는 것을 방지하기 위한 에어콘 압축기의 보호방법에 관한 것으로, 엔진구동의 여부를 판단하는 단계; 엔진구동이 수행되면 에어콘이 작동하는지를 판단하는 단계; 에어콘이 작동되면, 가속폐달의 답력조건에 따라 스로틀위치 센서(2)에서 감지한 스로틀밸브의 개도상태가 0%보다 큰가를 판단하는 단계; 상기 스로틀밸브의 개도상태가 0%보다 크면, 주행조건에 따라 차량속도가 0보다 큰가를 판단하는 단계; 차량속도가 증가함에 따라 엔진회전수를 제어하되, 상기 엔진회전수가 기설정회전수보다 이상이면 상기 엔진구동, 에어콘 작동, 스로틀밸브의 개도상태 및 차량속도의 조건에 따른 제반신호를 전자제어장치(1)에서 입력받아 에어콘 작동을 절체하는 단계를 제공한다.The present invention relates to a protection method of an air conditioner compressor for preventing a failure according to a load excessively applied to the compressor when the engine speed is high during the air conditioner operation of the vehicle, comprising: determining whether to drive the engine; Determining whether the air conditioner operates when engine driving is performed; Determining whether the opening state of the throttle valve detected by the throttle position sensor 2 is greater than 0% according to the pedaling condition of the accelerator pedal when the air conditioner is activated; If the opening state of the throttle valve is greater than 0%, determining whether the vehicle speed is greater than zero according to a driving condition; The engine speed is controlled as the vehicle speed is increased, and when the engine speed is higher than the preset speed, the electronic control device transmits various signals according to the engine driving, air conditioner operation, the opening state of the throttle valve, and the vehicle speed. It receives the input from 1) provides a step of switching the air conditioning operation.
