ACTIVE SUSPENSION APPARATUS |
摘要 |
An active suspension apparatus detects a relative displacement (x) between an axle and a vehicle body, discriminates a road surface state in accordance with the relative displacement and a change rate (x) in unit time which is derived from the relative displacement (x), and optimally controls characteristics of damping forces of hydropneumatic suspensions in accordance with a discrimination result (i.e., a road surface state). This discrimination is performed in accordance with a sum (Ax+Bx) of a signal obtained by multiplying the relative displacement (x) with a predetermined coefficient and a signal obtained by multiplying the change rate (x) with another predetermined coefficient. These coefficients are obtained in accordance with riding comfort against vibrations. The characteristics of the damping force of the hydropneumatic suspension are controlled by controlling the opening of throttle valves disposed between hydropneumatic chambers and actuators. |
