Abstract

본 발명은 차량자동변속기의 변속레버변화에 따른 변속충격방지방법에 관한 것으로, 자동변속기(1)가 엔진(1′)과 각종 구성부들을 제어하는 TCU(8)및 ECU(9)에 의해 제어 되도록 전기적으로 서로 연결되어 폐회로를 구성함과 더불어, 상기 TCU(8)에 의해 변속레버변환부(5)의 작동변화에 따른 엔진의 점화시기 점화지연범위(R)로 판단 되어져, 엔진의 토오크를 감소시켜 주므로 인해 자동변속기의 변속시 발생되는 기어치합에 따른 변속충격을 최소화 시킬 수 있게 됨은 물론, 자동변속기의 내구성과 상품성도 향상될 수 있도록 된 것이다.The present invention relates to a shift shock prevention method in accordance with a shift lever change of a vehicular automatic transmission and more particularly to an automatic transmission 1 in which an automatic transmission 1 is controlled by a TCU 8 and an ECU 9 which control an engine 1 ' And the ignition timing ignition delay range R of the engine is determined by the TCU 8 as a result of the change in the operation of the shift lever change portion 5 so that the torque of the engine The shift shock due to gear engagement occurring in shifting of the automatic transmission can be minimized, as well as the durability and merchantability of the automatic transmission can be improved.

Description

차량자동변속기의 변속레버변화에 따른 변속충격방지방법A method of preventing a shift shock according to a shift lever change of a vehicle automatic transmission

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제1도는 일반적인 자동변속기의 내부 작동구조를 도시한 개략적인 구성도, 제3도는 (A)는 점화지연범위를 도시한 선도이며, (B)는 점화지연 신호의 작동상태를 도시한 선도, 제4도는 본 발명에 따른 점화지연에 의한 변속시 변속충격을 방지하도록된 제어 흐름도이다.FIG. 1 is a schematic diagram showing an internal operating structure of a general automatic transmission, FIG. 3 (A) is a diagram showing an ignition delay range, (B) is a diagram showing an operating state of an ignition delay signal, 4 is a control flow chart for preventing a shift shock upon shifting by ignition delay according to the present invention.

Claims (1)

차속의 상태에 따라 자동변속기(1)가 적절히 조작되어 지게 되면 각 신호라인을 통해 TCU(8)내로 입력되는 현재의 변속단수범위 상태와 현재의 스로틀밸브개도량과 브레이크스위치상태에 따라 현재의 운전상태를 판단하게 되고, 이어 변속레버변환부(5)를 통해 현재의 차속에 따라 변화된 변속단수를 검출하여 각 변속단수에 따른 신호로 변환되어 상기 ECU(8)로 입력되어 지며, 이어 상기와 같은 신호를 입력받은 ECU(8)은 다시 브레이크 스위치입력량과 스로틀밸브개도량이 “0”임을 확인하게 되면 이 신호에 따라 상응하도록 매 1℃씩-1℃에서-10℃의 단계로 구분된 지연범위각도(R)중 한 값을 결정하여 ECU(9)로 전송하게 되면 이 ECU(9)의 신호에 따라 엔진 (1′)의 점화제어장치 (1a′)가 주어진 간격만큼 점화지연 되어 지도록 된 차량자동변속기의 변속레버 변화에 따른 변속충격방지방법.When the automatic transmission 1 is appropriately operated according to the vehicle speed, the current driving speed according to the current shift range range state inputted into the TCU 8 through each signal line, the current throttle opening amount and the brake switch state And then the transmission gear ratio changed in accordance with the current vehicle speed is detected by the shift lever converting unit 5 and converted into a signal corresponding to each gear ratio and inputted to the ECU 8, When the ECU 8 confirms that the brake switch input amount and the throttle valve opening amount are again " 0 ", the ECU 8 receives a signal and outputs a delay range angle The ignition control device 1a 'of the engine 1' is controlled by the signal of the ECU 9 so that the ignition control device 1a ' Shift lever of transmission Shift shock prevention method according to the screen. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
