Abstract

An automatic transmission controlling in restarting after temporary stop during car running comprising the step stopping the operation of a brake in restarting; the step automatically shifting the transmission to D by opening a throttle valve; and the step controlling car speed to the speed corresponding to the open degree of said valve is disclosed. Thereby, it is possible to reduce driver's fatigue, to reduce fuel and to improve the life of the transmission lever because the automatic shifting of D =´N =´D is embodied without driver's operation in restarting after temporary stop.

본 발명은 자동변속기의 제어에 관한 것으로, 특히 주행중 일정시간 이상 정지하는 경우 운전자의 변속레버 조작없이 변속기제어부에 자동변속기를 제어하여, N단으로 변속하고, 재출발시 액셀 페달의 작동에 따라 변속단을 원위치시켜 주행되도록 하여 운전자의 피로감을 줄이며 자동변속기의 변속 레버의 수명을 연장시키기 위한 주행중 일시정지후 재출발시 자동변속기 제어방법에 관한 것이다.The present invention relates to the control of an automatic transmission, and in particular, when the vehicle stops for a certain time while driving, the automatic transmission is controlled to the transmission control unit without operating the shift lever, and shifted to the N stage, and the gear stage according to the operation of the accelerator pedal when restarting. The present invention relates to an automatic transmission control method when restarting after a temporary stop while driving to reduce the driver's fatigue and extend the life of the shift lever of the automatic transmission.

종래의 자동변속기는 제1도에 나타낸 바와 같이, 운전자가 변속 레버를 D단에 놓고 주행하다가 일시정지를 위해 브레이크 페달을 밟으면 차속이 감소하면서 정지하게 된다. 정지후 재출발을 위한 브레이트 페달에서 발을 떼기만 하면 느린 속도로 주행이 시작되었다.In the conventional automatic transmission, as shown in FIG. 1, when the driver drives the shift lever to the D stage and presses the brake pedal for pausing, the vehicle speed decreases and stops. After stopping, just let go of the brate pedal for re-start, and it started running at a slow pace.

또한, 도심정체가 심한 곳에서는 주행중에 정지/출발동작을 반복해야 하므로, 주행도중에 일시정지하는 시간이 길어지는 경우에는 연비를 줄이기 위해 변속 레버를 N단에 놓고 브레이크를 밟고 있거나 또는 변속 레버를 P단에 두어야만 했다.In addition, stop / start operation must be repeated while driving in places with heavy traffic, so if the pause time is longer during driving, put the shift lever on the N-stage and press the brake or shift the shift lever to reduce fuel economy. Had to put on the Dan.

그러나 이러한 종래의 자동변속기는, 정체가 심한 도심을 주행하는 경우 주행중에 자주 정지/출발동작을 반복하므로, 그때마다 변속 레버를 조작해야 하는 운전자의 피로가 가중되며 잦은 변속 레버의 조작으로 변속 레버의 수명을 단축시키는 문제점이 있었다.However, since the conventional automatic transmission repeats the stop / start operation frequently while driving in a city with heavy traffic, the driver's fatigue that requires operating the shift lever is increased each time and the shift lever is frequently operated. There was a problem of shortening the life.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위한 것으로, D단으로 (Transmission Control Unit : TCU)로 구성된다.An object of the present invention is to solve the conventional problems as described above, consisting of a D stage (Transmission Control Unit: TCU).

본 발명 주행중 일시정지후 재출발시 자동변속기 제어방법을 첨부한 제2도와 제3도를 참조하여 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to FIG. 2 and FIG. 3 attached to the automatic transmission control method when restarting after stopping during driving.

D단으로 주행중 운전자가 브레이크 페달을 밟아 정지한 후 일정시간 이상이 흐르면, 즉 운전자가 브레이크 페달을 밟아 브레이크 페달 스위치(2)가 온되어 일정시간(T)이 흐르면, 변속기제어부(TCU)는 자동변속기(A/T)에 현재 변속단인 D단을 N단으로 변속하라는 신호를 출력한다. 그러면 상기 자동변속기(A/T)는 운전석에 위치한 변속 레버는 그대로 D단으로 놓은 채 현재 변속기를 D단에서 N단으로 작동시킨다.When the driver presses the brake pedal and stops while driving to the D stage, if the predetermined time passes, that is, when the driver presses the brake pedal and the brake pedal switch 2 is turned on and the predetermined time T passes, the transmission control unit TCU automatically operates. Outputs a signal to the transmission (A / T) to shift the D gear stage to the N gear stage. Then, the automatic transmission A / T operates the current transmission from D to N stages while leaving the shift lever located in the driver's seat as the D stage.

상기 작동으로 D단에서 N단으로 변속하여 정지하고 있는 상태에서 재출발을 위해 운전자는 브레이크 페달에서 발을 뗀 다음, 액셀 페달을 밟는다. 그러면, 브레이크 페달 스위치(2)가 오프되고 액셀 페달을 밟음으로 스로틀 포지션 센서(TPS)로부터 신호가 인가되므로 상기 변속기제어부(TCU)는 자동변속기(A/T)에 N단으로 처음상태인 D단으로 변속하라는 신호를 출력한다. 이때, 상기 자동변속기(A/T)는 운전석에 위치한 변속 레버의 현재 위치인 D단으로 변속기를 작동시킨 다음, 상기 스로틀 포지션 센서(TPS)로부터 인가되는 스로틀 밸브의 열림정도에 따라 가속하게 된다.In the above operation, the driver takes his foot off the brake pedal and then presses the accelerator pedal for restarting while the vehicle shifts from the D stage to the N stage. Then, since the brake pedal switch 2 is turned off and a signal is applied from the throttle position sensor TPS by depressing the accelerator pedal, the transmission control unit TCU is the first stage N of the automatic transmission A / T. Outputs a signal to shift to. At this time, the automatic transmission A / T operates the transmission to the D stage, which is the current position of the shift lever located in the driver's seat, and then accelerates according to the opening degree of the throttle valve applied from the throttle position sensor TPS.

다시 말하면, 상기 변속기제어부(TCU)는 종래와 같이 운전자가 브레이크 페달에서 발을 떼면, 즉 브레이크 페달 스위치(2)가 오프되는 시점(t1)에서가 아니라 브레이크 페달 스위치(2)가 오프된 다음 운전자가 액셀 페달을 밟으면, 즉 스로틀 포지션 센서(TPS)로부터 신호가 인가된 시점(t2)에서 N단을 D단으로 변속하도록 제어한다.In other words, the transmission control unit (TCU) is the conventional brake pedal switch (2) is turned off after the driver's foot off the brake pedal, that is, at the time (t 1 ) when the brake pedal switch (2) is off When the driver presses the accelerator pedal, that is, at the time t 2 at which the signal is applied from the throttle position sensor TPS, the N stage is shifted to the D stage.

이상에서 살펴 본 바와 같이, 본 발명 주행중 일시정지후 재출발시 자동변속기 제어방법은, 주행중 일정시간 이상 정지하여 재출발하는 경우에 운전자의 변속 레버 조작 없이 D단→N단→D단으로 자동변속되므로, 운전자의 피로를 줄일 수 있으며 정지중 연비를 절감할 수 있고, 변속 레버의 수명을 연장할 수 있는 유용한 것이다.As described above, the automatic transmission control method when restarting after the temporary stop during driving of the present invention is automatically shifted to D → N → D without operating the shift lever when the driver restarts after stopping for a predetermined time while driving. It is useful for reducing driver fatigue, fuel economy during stop, and extending the life of the shift lever.
