Abstract

본 발명은 자동 변속기 장착 차량이 내리막길을 주행할 때 운전자가 악셀레이터에서 발을 떼는 순간 TCU가 이를 감지하여 현재 변속단에서 1단 낮추도록 하여 자동적으로 엔진 브레이크가 걸리도록 한 자동 변속기의 엔진 브레이크 제어 장치 및 그 제어 방법에 관한 것으로서, 악셀레이터 페달에서 이 페달이 운전자의 발로부터 떼어지면 온되고 TCU에 접속되는 스위치(4)와, TCU에 접속되며 차량이 수평을 유지하고 있는지 아닌지를 판별하는 수평감지센서(3)와, 스위치(4) 및 센서(3)의 신호에 의해 변속실행기구(1)에 현 변속단에서 1단 낮은 변속을 지령하는 TCU(2)로 구성된다.According to the present invention, when the vehicle with the automatic transmission drives downhill, the TCU senses the moment when the driver releases the accelerator from the accelerator and lowers the engine by one step from the current shift stage. A device and a method for controlling the same, comprising: a switch (4) connected to the TCU that is turned on and connected to the TCU when the pedal is released from the driver's foot in the accelerator pedal, and horizontal sensing that determines whether the vehicle is leveled or not; It consists of the sensor 3 and the TCU 2 which instructs the shift execution mechanism 1 to transmit low gears by one step at the current shift stage by signals of the switch 4 and the sensor 3.
