Abstract

신장측 및 압축측 중 어느 한 감쇠력을 크게 설정할 수 있는 쇽업소버를 사용한 감쇠력 제어에 있어서, 특히 중·고속 주행상태에서 차체요동입력으로서 작용하는 작은 스프링상의 상하 속도에 대하여 감쇠효과를 높여서 들뜨는 감을 제거한다.In damping force control using shock absorber which can set either damping force of extension side or compression side largely, it raises the damping effect with respect to the up and down speed on the small spring acting as the body oscillation input, especially in the medium and high speed driving state to eliminate the feeling of lifting. do.

차속검출치 V의 증가와 함께 단계적으로 증가되는 목표포지션 역치 P1,-P1을 설정하고, 스프링상의 상하 속도 X2i'에 대하여 선형적으로 설정되는 목표포지션 P1~-P1사이에 있을때에는, 목표포지션 PD를 신장축 목표포지션 역치 P1에 설정하고, 스프링상의 상하 속도 X2i가 작은 값일때에는 그 신장측 목표포지션 P1에 있어서의 신장측 높은 감쇠력 D/FT1이 항상 발휘되도록 하며, 작은 차체 요동입력도 신속하게 감쇠 수속시켜, 이에 의하여 차량 주행중의 안정감이 높아지는 구성으로 하였다.Set the target position thresholds P 1 and -P 1 which are gradually increased with the increase of the vehicle speed detection value V and be between the target positions P 1 to -P 1 set linearly with respect to the vertical velocity X 2i 'on the spring. In this case, the target position P D is set to the extension axis target position threshold P 1 , and when the vertical velocity X 2i on the spring is a small value, the expansion-side high damping force D / F T1 at the extension-side target position P 1 is always exerted. In addition, a small body oscillation input can be quickly attenuated, thereby increasing the stability of the vehicle while driving.
