Abstract

전륜형 4륜구동 자동 변속차량이 오르막 길 경사로에서 차량의 무게 중심이 후륜으로 편중되어 전륜의 접지력이 작아짐으로서 발생되는 타이어의 슬립을 방지하고자, 2륜구동과 4륜구동의 선택을 감지하는 절환레버 스위치로 현재의 구동상태를 판단하는 단계와, 오르막 길 경사로 주행인 가를 판단하는 단계와, 아이들 스위치가 오프 상태인가를 판단하는 단계와, 급 조향 상태인가를 판단하는 단계를 포함하여 이루어지며, 상기한 단계들이 조건을 만족하면 솔레노이드 밸브를 듀티제어하여 유압제어식 다판 클러치를 작동시키는 4륜구동 자동 변속차량의 엔진동력 분배방법을 제공한다.Front wheel type four-wheel drive automatic shifting vehicle is a switching lever switch that detects the selection of two-wheel drive and four-wheel drive to prevent tire slip caused by the center of gravity of the vehicle being biased to the rear wheel on the uphill slope and the traction of the front wheel is reduced. Determining the current driving state, determining whether the vehicle is driving uphill, determining whether the idle switch is in an off state, and determining whether it is in a steer steering state. When these conditions are met, the solenoid valve is duty-controlled to provide an engine power distribution method for a four-wheel drive automatic transmission vehicle that operates a hydraulically controlled multi-plate clutch.
