Abstract

목적purpose

주행중 운전자가 선택 레버를 조작하여 기어를 하향 변속하는 경우, 변속 실시후 자동 변속기의 기어 위치를 판단하여 그에 따른 선택적인 유압 제어를 할 수 있도록 하는 자동 변속 차량의 선택 레버 조작에 의한 엔진 브레이크 시의 유압 제어 장치를 제공한다.When the driver shifts the gear downward by operating the selector lever while driving, when the engine brake is operated by operating the selector lever of the automatic transmission vehicle to determine the gear position of the automatic transmission and perform selective hydraulic control according to the shifting operation. Provide hydraulic control device.

구성Configuration

관련 센서들로부터 제어 정보를 읽는 초기 단계와, 선택 레버의 위치를 판단하는 선택 레버 판단 단계와, 현재의 스로틀 개도치와 설정 스로틀 개도치를 비교하는 스로틀 개도 판단 단계와, 기어위치를 검출하는 검출 단계와, 기어의 위치를 판단하는 기어 판단 단계와, 상기한 선택 레버 판단 단계, 스로틀 개도 판단 단계, 그리고 기어 판단 단계에서의 조건에 모두 해당되는 경우의 피즈댁 제어 단계와, 한편 상기한 선택 레버 판단 단계, 스로틀 개도 판단 단계, 그리고 기어 판단 단계에서 주이진 모든 조건 중 어느 하나라도 만족하지 않는 경우의 정상 제어 단계의 수으로 제어된다.An initial step of reading control information from related sensors, a selection lever determination step of judging the position of the selection lever, a throttle opening degree determination step of comparing the current throttle opening value and a set throttle opening value, a detection step of detecting the gear position; , A gear determining step for determining the position of the gear, a step control control when all of the selection lever determination step, the throttle opening degree determination step, and the gear determination step correspond to the conditions, and the selection lever determination step described above. It is controlled by the number of normal control steps in the case where any one of all main conditions in the throttle opening degree determination step and the gear determination step is not satisfied.
