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 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 vehicle suspension includes a variable damping effectiveness type shock absorber, which has an actuator and according to selective actuation thereof can be set to first, second, or third conditions which respectively cause the shock absorber to provide minimum, medium, or maximum damping effect. A control system for this suspension includes: a means for detecting one or more parameters relating to the operational condition of the vehicle and for outputting information signals representative thereof; a means for being manually controlled by an operator and for selecting between first manual, second manual, and auto operational modes; and a control means for: when the manual selecting means is selecting the first manual mode, actuating the actuator to its first condition; when the manual selecting means is selecting the second manual mode, actuating the actuator to its second condition; and, when the manual selecting means is selecting the auto operational mode, actuating the actuator to one of a set of its conditions including its first condition and its third condition according to the information signals outputted by the detecting means. The vehicle operational parameters may include steering angle and vehicle speed which can cause body roll, jerk and sharp acceleration which can cause vehicle squat, braking which can cause vehicle nose diving, and vehicle shift-offable state which can cause starting squat and tail lift; and this selective increase of shock absorber damping effect when these parameters take on troublesome values prevents these problems.

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.
