The present invention relates to a method to control vehicle braking on a road with split-μ, capable of satisfying the reduction of noise and the optimization of braking performance at the same time. The method includes a first step of sensing a road with split-μ while driving a vehicle; a second step of reducing the pressure of an operating wheel to a braking pressure level while forcibly reducing the pressure to a level for steering toward the opposite direction to a direction in which the vehicle moves; and a third step of forming a control pattern to operate an ABS device while compensating for a brake pressure value and a moving level value of the vehicle under linear flow control (LFC) applied to a road surface having a high slip coefficient.

    본 발명은 차량 주행시 복합 노면(road with split-μ)임을 감지하는 제1 단계; 상기 차량이 쏠리는 방향의 반대 방향으로 조향이 가능한 수준으로 구동 차륜을 강제 감압시키면서 제동 압력의 수준으로 감소시키는 제2 단계; 및 마찰계수가 높은 노면에서 적용되는 선형 유압 제어(Linear Flow Control, 이하 LFC) 시의 차량의 쏠림 정도값과 브레이크 압력값으로 보상하면서 ABS 장치가 작동되도록 제어 패턴을 형성하는 제3 단계;를 포함하여 차량의 제동 성능 최적화 및 노이즈 저감을 동시에 만족하기 위한 복합 노면에서 차량 제동 제어 방법에 관한 것이다.
