摘要： A suspension control system for an automotive vehicle automatically adjusts the damping strength of variable shock absorbers or other dampers in accordance with road surface conditions as recognized by frequency analysis of a vehicle height or vibration sensor signal. The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels or unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands and the amplitude of each is compared to a corresponding reference level to give an indication of the irregularities in the road surface. Specifically, a high-amplitude low-frequency component indicates large-scale bumps and dips capable of bouncing the vehicle whereas a strong high-frequency component reflects a rough-textured road surface, such as gravel. The comparison information is sent to a suspension system controller which causes actuation of the shock absorbers to a hard mode of operation when the low-frequency sensor signal components are relatively strong.

摘要： A suspension control system can precisely control the damping characteristics of vehicular suspension for successfully and satisfactorily providing anti-dive and anti-rebound feature. The suspension control system is adapted to detect vehicle deceleration on the basis of a variation of a vehicle speed and to compare the vehicle speed with a predetermined vehicle speed criteria across which damping characteristics of the vehicular suspension vary between a harder suspension mode and a softer suspension mode. The vehicle speed criteria is variable depending upon vehicle deceleration so that the criteria becomes higher when the magnitude of deceleration is greater than a predetermined level. By hardening the suspension at an earlier timing during relatively abrupt deceleration of the vehicle, the magnitude of nose dive is reduced and the magnitude of rebounding motion after nose-dive can be reduced. This assures riding comfort by reducing the magnitude of pitching behavior of the vehicle front end. On the other hand, by providing later timing for hardening the suspension while deceleration of the vehicle is relatively low, softer damping characteristics can be maintained for a longer period to assure riding comfort by successfully absorbing bounding and rebounding shock from the road surface.

摘要： A suspension control system is able to precisely adapt damping characteristics to the road condition, even when the vehicle passes over bump, manhole, hole and so forth. The suspension control system includes a road sensor which produces a road condition indicative signal. A controller is adapted to recognize bump, manhole, hole and so forth which causes temporary bounding and rebounding motion for the vehicle, on the basis of the road condition indicative signal from the road sensor. The controller produces a control signal to harden damping characteristics of suspension when bump, manhole, hole and so forth is detected with a given delay time. The delay time for changing damping characteristics is different at the front and rear suspension from each other so that each of the front and rear suspension can be stiffened at a good timing.

摘要： A suspension control system includes an actuator which adjusts the damping or shock absorbing characteristics of the suspension system among a plurality of predetermined characteristics. Occurrences of actuation of the actuator are counted and the count is compared with a given value to gain a measure of secular variation of the suspension system. When the count exceeds the given value, a reference value used by the suspension control system is adjusted to compensate for secular variation of the suspension system. With this arrangement, the suspension controlling characteristics can be fitted to the condition of the suspension system even after secular variation.

摘要： In a vehicle vibration damping force control system, rolling, pitching and bouncing motions are detected independently in a predetermined priority order; each detected motion is compared with respective predetermined levels; if each detected motion exceeds each predetermined level, hydraulic switch valves are controlled so that operating fluid energized by stroke changes of the hydraulic cylinders due to the detected vibration motion is passed through damping force generating mechanisms to increase a damping force against only the detected vibration motion, without generating any other damping forces against other non-detected vibration motions. Since only the necessary damping force is generated against only the detected vibration motion, the damping force is minimized to maintain vehicle riding comfort.

The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels of unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands, the amplitude of each of which is compared to a corresponding reference level.

The comparison information is sent to a suspension system controller which causes actuation of the shock abosrbers to a stiffer mode of operation when the low-frequency sensor signal components are relatively strong.
