Disclosed is a brake traction control system (BTCS) to enable a vehicle to effectively escape from a snowy slope or sand field. According to one embodiment of the present invention, the brake traction control system comprises: a plurality of wheel speed detection units detecting a wheel speed of each wheel; a hydraulic adjustment unit adjusting the brake pressure of each wheel; and an electronic control unit. When, during BTCS control, the vehicle speed is less than a predetermined speed, the vehicle is driven on a road surface with significant external driving resistance or is stopped, and the left and right hunting brake count is greater than a predetermined value, then the electronic control unit decreases at least one of several values, each of which is a BTCS entry threshold value, a BTCS control escape threshold value, and a fade-out brake control amount for BTCS cancelation with respect to the BTCS control to a smaller value than that of normal BTCS control. If not one of those mentioned above, brake control amount value will increase corresponding to the speed difference between left and right driving wheels in the BTCS control to a value greater than that of the normal BTCS control.

    브레이크 트랙션 제어 시스템이 개시된다. 본 발명의 일실시예에 따른 브레이크 트랙션 제어 시스템은 각 바퀴의 휠 속도를 감지하는 복수의 휠 속도 감지부와, 각 바퀴의 브레이크 압력을 조절하는 유압조절부 및 BTCS(Brake Traction Control System) 제어시 차량의 속도가 미리 설정된 속도보다 낮고 외부 주행 저항이 큰 노면을 주행하거나, 차량이 정차 중이고 좌우 헌팅 브레이크 카운트가 미리 설정된 값보다 크면, BTCS 제어의 BTCS 진입임계값, BTCS 제어탈출임계값 및 BTCS 해제를 위한 페이드 아웃 브레이크 제어량 중 적어도 하나를 각 정상 BTCS 제어인 경우보다 감소시키거나, BTCS 제어의 좌우 구동륜 속도 차이에 대응하는 브레이크 제어량을 정상 BTCS 제어인 경우보다 증가시키는 전자제어유닛을 포함한다.
