Abstract
본 발명은 차량 전자제어식 현가장치의 현가변위 측정방법에 관한 것으로, 종래 차고센서(10)는 차체나 노면으로부터 하중 또는 부하변동에 따른 현가변위 변화를 감지하여 ECU로 송출하고 ECU는 적절한 현가변위를 유지하기 위한 제어를 수행하여 차량의 적정한 승차감을 유지시켜야 하는바, 상기 콘트롤아암(14)의 회동에 따른 각도의 변화에 의한 현가변위의 측정은 상기 개발진행 중의 전자제어 현가장치에 있어, 단순히 길이의 변동만을 감지할뿐 상술된 바와 같이 현가장치의 부하변동에 따른 정밀한 현가변위의 변동을 ECU에 제공할 수 없다.The present invention relates to a method of measuring the suspension displacement of an automobile electronically controlled suspension device. The conventional height sensor 10 senses a change in suspension displacement due to load or load variation from a vehicle body or a road surface, It is necessary to maintain an appropriate ride quality of the vehicle by performing control for maintaining the control arm 14. The measurement of the suspension displacement due to the change in the angle of the control arm 14 due to the rotation of the control arm 14 is merely a function of the length But can not provide the ECU with a precise fluctuation of the suspension displacement due to the load variation of the suspension.
이에 본 발명은 예시도면 제4도에서와 같이 코일스프링(18)에 스트레인 게이지(22)를 장착하여 상기 코일스프링에 작용하는 응력으로부터 현가변위를 측정함으로써 상기 문제점을 해소한 것이다.The present invention solves the above problem by mounting a strain gauge 22 on the coil spring 18 and measuring the displacement of the suspension from the stress acting on the coil spring, as shown in FIG.
