Abstract

본 발명은 수동변속기 장착차량의 변속시 가속페달을 계속 밟음조작하더라도 엔진공회전수가 과도상승되지 않도록 하는 차량변속시의 엔진공회전 제어장치에 관한 것이다.The present invention relates to an engine idling control apparatus for a vehicle shift during a shift of a vehicle equipped with a manual transmission so as not to excessively increase engine idling speed even if the accelerator pedal is continuously operated.

본 발명은 차륜의 회전속도를 검출하는 휠스피드센서(21), 엔진에 가중되는 부하상태를 검출하는 토오크감지센서(22) 및 변속기어의 중립상태여부를 검출하는 시프트레버센서(23)를 포함하는 변속감지수단(20)과; 상기 변속감지수단(20)의 출력신호로 차량의 주행상태와 운전자가 행하는 변속조작의 진행상태 및 완료상태를 판별하여, 변속조작의 진행시에는 타코미터(30)의 엔진회전속도신호로 일정속도이상의 엔진공회전상태를 판별하여 구동전류를 출력하고, 변속조작의 완료시에는 구동전류의 출력을 정지하는 전자제어유닛(40)과; 상기 전자제어유닛(40)으로 포지션센싱의 신호를 출력하며 상기 전자제어유닛(40)의 구동전류에 따라 정/역회전되어 드로틀밸브(13)의 개구를 조절하는 서보모터(50)로 구성된 것을 특징으로 한다.The present invention includes a wheel speed sensor 21 for detecting the rotational speed of the wheel, a torque detecting sensor 22 for detecting a load state which is being weighted to the engine, and a shift lever sensor 23 for detecting whether the transmission is in a neutral state (20); The output signal of the speed change sensing means 20 is used to determine the traveling state of the vehicle and the traveling state and completion state of the shifting operation performed by the driver so that the engine speed signal of the tacho- An electronic control unit (40) for outputting a drive current by discriminating an idle state of the engine and stopping outputting a drive current upon completion of a shift operation; And a servomotor 50 that outputs a signal of position sensing to the electronic control unit 40 and adjusts the opening of the throttle valve 13 by forward / reverse rotation in accordance with the driving current of the electronic control unit 40 .
