Abstract

D레인지 3,4속의 고속 주행도중에 운전자의 실수로 N레인지로 절환되는 것을 방지하여 안전운행에 기여할 수 있도록 한 차량용 자동변속기의 오조작 방지시스템을 제공할 목적으로; 오일펌프에서 발생한 유압으로 전진과 후진 속도에 비례하여 다수개의 마찰요소를 제어함으로써, 토오크컨버터의 회전력을 각각의 기어요소들로 선택적으로 전달하는 밸브들을 포함하는 자동변속기의 유압제어시스템에 있어서, 운전자의 선택레버 조작에 연동되면서 각 변속단의 유롤 선택하는 매뉴얼 밸브에 기존 랜드와 직경이 다른 랜드를 추가 설치하여 이에 D레인지 3,4속에서 작동하는 마찰요소로 공급되는 유압의 일부가 작용토록 한 차량의 자동변속기의 오조작 방지시스템을 제공한다.To provide a misoperation prevention system for an automatic transmission for a vehicle that prevents a driver's mistake of switching to the N range during a high-speed driving of the D-range 3 and 4 speeds, thereby contributing to safe driving; In the hydraulic control system of an automatic transmission comprising a valve for selectively transmitting the torque of the torque converter to the respective gear elements by controlling a plurality of friction elements in proportion to the forward and reverse speed by the hydraulic pressure generated from the oil pump In addition to installing a different land diameter than the existing land, a part of the hydraulic pressure supplied to the friction elements operating in the D-range 3 and 4 is applied to the manual valve that selects the oil roll of each shift stage. Provides a system for preventing tampering of an automatic transmission of a vehicle.
