Abstract
차량의 속력을 감지한 뒤에 이를 전기적인 신호로 변환하여 출력하는 차속센서(10)와, 상기한 차속 센서로부터 입력되는 신호를 이용하여 차량의 속도를 감지한 뒤에, 차량의 속도가 급격하게 감속하는 경우에 순차적으로 다운 시프트가 이루어지도록 하기 위한 제어신호를 출력하는 마이크로 컨트롤러(20)와, 상기한 마이크로 컨트롤러로부터 입력되는 제어신호에 따라 유압이 동작되도록 함으로써 변속이 일어나도록 하는 시프트 밸브(30)를 포함하여 이루어지며, 차량의 속력이 급감속되는 경우에 순차적으로 다운 시프트가 이루어지도록하여 엔진 브레이크가 발생되도록 함으로써 제동특성을 향상시킬 수 있는 효과를 가진 급감속시 엔진 브레이크 기능을 갖는 자동변속 제어방치 및 그 방법을 제공한다.The vehicle speed sensor 10 detects the speed of the vehicle and converts it into an electrical signal and outputs the electrical speed. After detecting the speed of the vehicle using the signal input from the vehicle speed sensor, the speed of the vehicle decreases rapidly. In this case, the microcontroller 20 outputs a control signal to sequentially perform the downshift, and the shift valve 30 for shifting by causing the hydraulic pressure to operate according to the control signal input from the microcontroller. Automatic shift control with engine brake function during sudden deceleration with the effect of improving the braking characteristics by causing the engine brake to be sequentially downshifted when the speed of the vehicle is rapidly decelerated. And a method thereof.
