The present invention relates to a suspension malfunction determination system of a vehicle, comprising: a preview sensor disposed at the front of a vehicle body and recognizing a shape of a speed bump; an acceleration sensor for measuring an acceleration in a vertical direction of a vehicle; and a control unit calculating a calculation value that is a vertical acceleration value through the vehicle information including the shape of the speed bump recognized by the preview sensor and a type of the vehicle, the speed of the vehicle, a spring elasticity coefficient of a suspension, and a shock absorber damping coefficient of the suspension, and comparing the calculation value and a measured value measured by the acceleration sensor to determine suspension malfunction of the vehicle.

    차체의 전방에 배치되고, 과속방지턱의 형상을 인지하는 프리뷰 센서; 차량의 상하방향의 가속도를 측정하는 가속도 센서; 및 프리뷰 센서를 통해 인지한 과속방지턱의 형상과 차량의 종류, 차량의 속도, 현가장치의 스프링 탄성계수, 현가장치의 쇽업소버 댐핑계수를 포함하는 차량정보를 통해 수직 가속도 값인 계산값을 산출하고, 계산값과 가속도 센서에서 측정된 값인 측정값을 비교하여 현가장치의 성능 이상 여부를 판단하는 제어부;를 포함하는 차량의 현가장치 성능 이상 판단 시스템.이 소개된다.
