Abstract
본 발명은 전자 제어식 자동 변속기를 구비한 차량의 구배로 주행시 구배저항에 의한 밀림현상을 방지하기 위한 오르막 구배로에서의 밀림 방지 제어 방법에 관한 것으로, 전자 변속기에서 평상시의 토크 증배율로 오르막길에서 정차후 등판할 수 있는 경사각도를 임계치로 설정하는 제 1 과정과; 현재의 오르막길 경사각을 검출하는 제 2 과정과; 제 2 과정에서 검출된 경사각과 제 1 과정에서 설정된 임계치를 비교하는 제 3 과정과; 제 3 과정에서 임계치보다 검출된 경사각이 크다고 판단되면 출발시 엔진의 회전수를 증가시키는 제 4 과정을 포함하는 것을 특징으로 하는 오르막 구배로에서의 밀림 방지 제어방법을 적용한 토크 제어부(20)의 제어동작에 따라 전자 제어부(30)에서 엔진을 제어하여 운전자가 오르막 경사길에서 정차후 브레이크 페달에서 발을 떼어도 차량은 절대로 뒤로 후진하지 않게 되는 효과가 있다.The present invention relates to a control method for preventing rolling on an uphill slope to prevent a rolling phenomenon caused by a gradient resistance when driving a vehicle with an electronically controlled automatic transmission. A first step of setting a tilt angle that can be climbed after a threshold; A second process of detecting a current uphill inclination angle; A third process of comparing the inclination angle detected in the second process with a threshold set in the first process; And controlling the torque control unit 20 to which the rolling prevention control method is applied in the uphill gradient path, when the detected tilt angle is greater than the threshold value in the third process, the fourth process increases the rotation speed of the engine. According to the operation, the engine is controlled by the electronic control unit 30 so that the driver never stops backwards even when the driver stops on the uphill slope and releases the brake pedal.
