본 발명은 브레이크 트랙션 제어시스템의 제동압력 한계값 설정방법은, 구동휠에서 슬립이 발생되는 여부를 판단하는 단계, 구동휠의 슬립 발생시 BTCS 제어를 시작하는 단계, 고마찰 구동휠의 불안정성 발생 여부를 판단하는 단계, 저마찰 구동휠에 가해지는 제동압력을 누적하여 연산하는 단계, 제동압력 누적 연산값과 기설정된 저마찰 구동휠의 제동압력 한계값을 비교하는 단계, 제동압력 누적 연산값이 기설정된 저마찰 구동휠의 제동압력 한계값보다 크면 고마찰 구동휠의 슬립 발생시 저마찰 구동휠에 가해지는 제동압력을 한계값으로 설정하는 단계를 포함함으로써, 스플릿 노면으로 된 언덕길의 등판시 저마찰 구동휠에 설정된 한계값 이상으로 제동압력이 가해지는 방지함으로써, 등판 성능을 향상시킬 수 있는 것이다.

    Disclosed is a braking pressure threshold setting method of a brake traction control system. The method includes steps of: determining whether a slip occurs in a driving wheel; initiating a BTCS control when the slip occurs in the driving wheel; determining whether instability occurs in a high-frictional driving wheel; cumulatively calculating a braking pressure applied to the low-frictional driving wheel; comparing the cumulatively calculated braking pressure value and a pre-set braking pressure threshold of the low-frictional driving wheel; and, when the cumulatively calculated braking pressure value exceeds the pre-set braking pressure threshold of the low-frictional driving wheel, setting the braking pressure applied to the low-frictional driving wheel when the slip occurs in the high-frictional driving wheel, as the threshold. Thus, it is possible to prevent the braking pressure exceeding the pre-set threshold from being applied to the low-frictional driving wheel when climbing a slope road formed with a split road surface such that a climbing performance can be improved.
