Abstract

변속동작이 이루어질 때 감소하는 엔진 회전수를 이론 엔진 회전수로 증가시켜 클러치 페달에서 발이 떼어지는 순간 부드럽게 치합되어 주행할 수 있도록 하기 위한 변속 동작시 엔진 회전수 보상장치 및 그 방법을 제공하기 위하여, 클러치 페달의 동작상태에 따라 가변되어 해당하는 신호를 출력하는 클러치 동작 감지 스위치와; 변속단의 고정위치에 따라 동작상태가 가변되어 해당하는 신호를 출력하는 변속단 감지수단과; 자동차의 주행속도를 감지하여 해당하는 신호를 출력하는 차속 감지수단과; 엔진 회전수를 감지하여 해당하는 신호를 출력하는 엔진 회전수 감지수단과; 상기 클러치 동작 감지 스위치와 변속단 감지수단과 차속 감지수단과 엔진 회전수 감지수단에 연결되어, 클러치 동작 감지 스위치가 동작하면 자동차의 주행속도와 변속단수와 엔진 회전수를 판단하여 주행속도와 변속 단수에 해당하는 이론 엔진 회전수를 판단하고, 실제의 엔진 회전수와 이론 엔진 회전수가 동일하지 않을 경우에 클러치 페달 동작 감지 스위치의 상태가 가변될 때 엔진 회전수를 제어하기 위한 제어신호를 출력하는 엔진 제어수단과; 상기 엔진 제어수단과 연결되어, 엔진 제어수단에서 인가되는 제어신호에 따라 동작하여 스로틀 밸브의 개도상태를 가변시키는 공회전 제어모터로 이루어져 있다.In order to provide an engine speed compensation device and a method thereof in a shifting operation for increasing the engine speed which decreases when the shifting operation is made to the theoretical engine speed so as to smoothly engage and run when the foot is released from the clutch pedal, A clutch motion detection switch that is variable according to an operation state of the clutch pedal and outputs a corresponding signal; A shift stage detecting means for varying an operating state according to a fixed position of the shift stage and outputting a corresponding signal; Vehicle speed detecting means for detecting a driving speed of the vehicle and outputting a corresponding signal; Engine speed detection means for sensing an engine speed and outputting a corresponding signal; It is connected to the clutch motion detecting switch, the shift stage detecting means, the vehicle speed detecting means, and the engine speed detecting means. When the clutch motion detecting switch is operated, the driving speed and the gear speed are determined by determining the driving speed, the gear speed, and the engine speed of the vehicle. An engine that determines the theoretical engine speed corresponding to the engine speed and outputs a control signal for controlling the engine speed when the state of the clutch pedal motion detection switch is changed when the actual engine speed and the theoretical engine speed are not the same. Control means; It is connected to the engine control means, consisting of an idle control motor for operating in accordance with the control signal applied from the engine control means for varying the opening state of the throttle valve.
