The present invention relates to a brake control method for preventing jerk occurring when a user takes off his/her foot from a brake pedal in case a vehicle is parked in a parking gear (P). To this end, the present invention provides a method for preventing jerk in such a manner that applies a predetermined amount of braking power to front/rear wheels by use of an electronic stability control (ESC) in accordance with vertical acceleration in a state a vehicle is parked or stopped, and then slowly relieves braking pressure. Specifically, the present invention may increase a drivers stability under any circumstances when the driver parks the vehicle in a P gear, in consideration of a case where vertical and horizontal acceleration occurs simultaneously due to no match between the vertical direction and inclination direction of the vehicle, as well as a case where the steering wheels of the vehicle is turned towards a different direction when the vehicle is parked on an inclined road.

    본 발명은 차량이 P단 주정차를 할 경우, 운전자 브레이크 페달 오프 시에 발생하는 저크(jerk)를 방지하기 위한 차량 제동 제어 방법이다. 이를 위해, 본 발명에서는 차량의 주정차 상태에서 종방향 가속도를 고려하여 ESC를 이용하여 일정한 제동력을 전/후륜 차륜에 인가하고 서서히 제동압을 빼줌으로써 저크(Jerk)를 방지하는 방법을 제공한다. 특히, 또한 차량의 종방향과 경사도 방향이 일치하지 않아 종/횡방향 가속도가 동시에 나올 경우뿐만 아니라, 경사로 주정차 시에 조향을 돌려놓는 경우를 고려하여, 어떠한 상황에서도 운전자에게 P단 주정차 시에 안정감을 향상시키는 것에 특징이 있다.
