Abstract

본 발명은 4L 저속변속기 엔진브레이크가 급격하게 작용되는 것을 방지하여 안전운행이 이루어지도록 된 차량의 사륜구동 자동변속기에 관한 것으로, 부변속기(1)의 저단기어위치를 감지하는 4L스위치(2)를 설정하고, TCU(3)에는 4L주행시 엔진(4)의 스로틀밸브센서(5)와, 주변속기(6)의 솔레노이드(7)와 차속센서(8), 및 이 부변속기(1)의 4L스위치(2)에서 신호를 인가 받도록 되어 있다.The present invention relates to a four-wheel drive automatic transmission of a vehicle to prevent a sudden operation of the 4L low-speed transmission engine brake to achieve a safe operation, the 4L switch (2) for detecting the low gear position of the sub-transmission (1) The throttle valve sensor 5 of the engine 4, the solenoid 7 and the vehicle speed sensor 8 of the peripheral gearbox 6, and the 4L switch of this sub-transmission 1 are provided in the TCU (3). In (2), a signal is applied.
