본 발명은 차량의 주행 안정성 확보를 위한 유압제동 제어 시 또는 회생제동과 유압제동의 협조 제어 시, 주행 상황에 따른 브레이크 패드의 마찰계수를 휠속, 디스크 온도, 제동 유압을 이용하여 실시간으로 예측하고, 예측된 마찰계수를 이용하여 계산되는 목표 제동토크를 결정한 다음, 결정된 목표 제동토크가 피드포워드 제어를 통하여 실제 제동토크에 반영되도록 함으로써, 제동 제어의 정확성 및 응답 속도를 향상시킬 수 있도록 한 브레이크 패드의 마찰계수 예측을 이용한 제동 제어 방법을 제공하고자 한 것이다.

    A braking control method using a predicted friction coefficient of a brake pad in a braking apparatus, which may predict a friction coefficient of a brake pad according to the traveling situation in real time using a wheel velocity, a brake disc temperature, and a braking hydraulic pressure, may include determining a target braking torque determined using the predicted friction coefficient, and then allowing the determined target braking torque to be reflected to a real braking torque through a feedforward control, upon a hydraulic braking control for securing the traveling stability of a vehicle or upon a cooperative control between the regenerative braking and the hydraulic braking, improving the accuracy and response speed of the braking control.
