Abstract

본 발명은, 종래의 기계적인 대쉬-포트 장치를 대신하여 아이들스피드컨트롤(ISC) 밸브의 제어에 의한 대쉬-포트기능을 수행하는 방법을 제공하기 위한 것이다.The present invention is to provide a method for performing a dash-port function by control of an idle speed control (ISC) valve in place of a conventional mechanical dash-port device.

본 발명은, 차량 엔진부의 대쉬포트기능에 있어서, 각종 센서로부터 감지된 냉각수온, 에어콘스위치 및 전기부하신호 등을 입력받아 목표회전수(NT)를 설정하는 단계와, 기관부에서 출력되는 실제 기관회전수(NA)와 상기 목표회전수(NT)를 서로 비교하는 단계, 스로틀 각신호와 차속신호등을 받아 아이들상태를 판별하는 단계, 아이들상태에만 비교부에서 신호를 받아 제어량을 계산하는 단계 및, 제어량계산부에서 구동신호를 받아 바이패스통로에 설치된 아이들스피드컨트롤(ISC) 밸브를 구동시키는 단계를 구비하여 대쉬-포트 기능을 수행하는 것을 특징으로 한다.The present invention, in the dashpot function of the vehicle engine unit, receiving the coolant temperature, air conditioner switch and electrical load signal detected from various sensors, and setting a target rotation speed (N T ), and the actual output from the engine unit Comparing the engine speed (N A ) and the target speed (N T ) with each other, determining the idle state by receiving the throttle angle signal and the vehicle speed signal, etc., receiving a signal from the comparator only in the idle state to calculate the control amount And driving the idle speed control (ISC) valve installed in the bypass passage by receiving the driving signal from the control amount calculating unit.

본 발명에 의하면, 가속중 가속페달을 떼면서 브레이크를 밟고 감속을 하게되면, 이 순간 전자제어장치(ECU)는 아이들상태라고 판단을 하고, 목표회전수(NT)를 계산하여 실제 기관회전수(NA)와 비교하여 제어량 계산을 하고, 아이들상태 판별에 따라 아이들스피드컨트롤(ISC) 밸브를 열고 닫음으로 해서 흡입공기의 급차단으로 발생하는 감속쇼크나 엔진의 스톨을 막고 정확한 전자제어를 행함으로써 좀더 완벽한 대쉬-포트 기능을 수행할 수 있다.According to the present invention, when the brake is released while decelerating the accelerator pedal during acceleration, the electronic control unit (ECU) determines that the engine is in the idle state at this moment, calculates the target rotation speed (N T ), and calculates the actual engine speed. The control amount is calculated in comparison with (N A ), and the idle speed control (ISC) valve is opened and closed according to the determination of the idling state to prevent deceleration shock or stall of the engine caused by sudden air cutoff, and to perform accurate electronic control. This allows you to perform a more complete dash-port function.
