하이브리드 차량 또는 전기 차량을 제동함에 있어서, 브레이크 페달입력에 따라 차량의 제동시 요구 가감속도와 실제 차량의 가감속도를 측정하여 제동장치 고장여부를 판단하고, 차량의 제동구간에 따라 요레이트 값과 가감속도의 변화를 측정하여, 회생제동장치 및 마찰제동장치고장을 판단하고, 마찰제동장치고장의 경우 고장대상 제동장치를 판단할 수 있는 방법을 제공한다.

    A method for detecting a malfunction of a brake system may include measuring a deceleration/acceleration upon braking and determining whether the brake system has the malfunction by comparing the measured deceleration/acceleration and a required deceleration/acceleration. If it is determined that the brake system has the malfunction, the method further includes determining whether a braking interval is an interval where braking is performed only through regenerative braking. If so, the method determines that a regenerative brake system has the malfunction. If not, the method further includes determining whether a left friction brake system or a right friction brake system has the malfunction by measuring a yaw rate value and determining whether a front wheel friction brake system or a rear-wheel friction brake system has the malfunction by using a variation amount of a measurement value of the deceleration/acceleration.
