Claims (1)

차륜과 차체사이에 설치된 차높이 조정용의 유체스프링실과, 상기 유체스프링실에 유체공급원으로부터 공급용 개폐밸브를 거쳐서 유체를 공급하는 유체공급수단과, 상기 유체스프링실로부터 배출용 개폐밸브를 거쳐서 유체를 배출하는 유체배출수단과, 차높이를 검출하는 차높이 센서와, 차체에 작용하는 상하방향의 가속도를 검출하는 가속도센서와, 상기 차높이 센서에 의해 검출된 차높이와 설정된 목표 차높이를 비교하여 차높이를 상기 목표 차높이로 향해 조정하도록 상기 공급용 개폐밸브 또는 상기 배출용 개폐밸브를 제어하는 제어수단과, 상기 차높이 센서에 의해 설정시간내에 차놓이의 설정범위를 초과하는 차높이를 설정회수이상 검출하는 제1조건을 만족할 때 혹은 상기 가속도 센서에 의해 설정시간내에 설정치를 초과하는 가속도의 변화를 설정회수이상 검출하는 제2조건을 만족할때에 나쁜길이라는 판정을 성립시키고 상기 차높이센서 및 가속도 센서에 의해 상기 제1조건 또는 제2조건의 어느 것도 만족하지 않을때에 나쁜길이라는 판정을 해제시키는 나쁜길 판정수단과, 통상시에는 상기 제어수간에 있어서의 목표 차높이로서 정상 차높이를 설정하고 상기 나쁜길 판정수단에 의해 나쁜길이라는 판정이 성립할때에는 목표 차높이로서 상기 정상 차높이보다 높은 차높이를 설정하는 목표 차높이 설정수단을 구비한 것을 특징으로 하는 차량용 현수장치.A fluid spring chamber for adjusting the vehicle height provided between the wheel and the vehicle body, a fluid supply means for supplying fluid to the fluid spring chamber from a fluid supply source through a supply opening / closing valve, and a fluid opening / closing valve from the fluid spring chamber. By comparing the fluid discharge means to be discharged, the vehicle height sensor for detecting the vehicle height, the acceleration sensor for detecting the acceleration in the vertical direction acting on the vehicle body, the vehicle height detected by the vehicle height sensor and the set target vehicle height Control means for controlling the supply opening / closing valve or the discharge opening / closing valve so as to adjust the vehicle height toward the target vehicle height, and setting the vehicle height exceeding a setting range of the vehicle seat within the set time by the vehicle height sensor; Acceleration exceeding a set value when the first condition for detecting abnormality is satisfied or within the set time by the acceleration sensor A determination is made that the road is a bad road when the second condition for detecting a change over the set number of times is satisfied, and the road is determined to be a bad road when none of the first condition or the second condition is satisfied by the vehicle height sensor and the acceleration sensor. The normal vehicle height is set as the target vehicle height between the control numbers in normal times, and the normal vehicle is used as the target vehicle height when the determination is made that the bad road is established by the bad road determination means. A suspension device for a vehicle, comprising: a target vehicle height setting means for setting a vehicle height higher than the height. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
