Abstract

본 발명은, 차량의 서스펜션장치에 관한 것이며, 특히 노면으로부터의 소정의 주파수의 전동입력을 효과적으로 취소할 수 있는 서스펜션장치에 관한 것으로서, 그 구성에 있어서, 본 서스펜션제어시스템은, 스프링상부질량의 가속도신호 ym을 피이드백제어하는 경로(passage)와, 스프링하부질량의 가속도신호 yL를 튜닝회로(71)에 인도해서, FIR 필터의 개인을 복귀하는 경로로 이루워진다. 이 시스템의 특징은 기준주파수(10∼12Hz근방)에 가까운 노면입력 ym에 대해서는, 이 ym을 취소하는 방향으로 작용하도록 튜닝이 행하여지는 것이다. 그 결과, 스프링상부질량이 기준주파수(10∼12Hz근방)에 가까운 노면입력 ym에 대해서 다이나믹뎀퍼로서 작용을 하나, 그 이외의 주파수영 역에서는 튜닝회로 (71)로부터의 가산기 (61)에의, 출력은 거의 0으로 되고, 통상의 스카이훅제어가 행하여진다. 스프링상부질량이 다이내믹댐퍼로서 작용하여도, 스프링상부질량은 스프링하부질량에 비해서 질량에서 압도적으로 우수하므로 불필요한 공진은 발생하지 않기 때문이다.
