    摘要: A suspension control system of the present invention varies a damping force according to a velocity ratio of a mass-body velocity to a relative velocity, while ensuring both a comfortable drive and stable cruising. In the suspension control system, a CPU calculates a mass-body velocity Zd and a relative velocity Yd based on detection signals from sensors and determines a velocity ratio Zd/Yd (steps S110 and S120). A small skyhook damping coefficient is set for a small vehicle speed V to reduce a damping force according to the velocity ratio Zd/Yd (step S130). In the process of varying the damping force, a stepping motor used for the variation in damping force is driven at a low driving frequency for a small vehicle speed V (step S180). While the vehicle runs at a relatively low speed, the suspension control system of the invention restricts the degree of variation in damping force and lowers the rate of variation in damping force, thereby relieving shocks or uncomfortableness due to a delayed control of damping force, which is caused by a delayed detection of the relative velocity or a delayed response of devices and substantially maintaining a drive.

    摘要: An actively-controlled resonant-type force generator (20) is adapted to be attached to a structure (21), and includes a mass (23) mounted for movement relative to the structure and a plurality of springs (22, 24) operatively arranged between the mass and the structure. A servoactuator (26) is arranged to controllably excite the mass-spring system. The actual force (F.sub.a) transmitted from the mass to the structure is compared with a commanded force (F.sub.c) to produce a force error signal (F.sub.e). The actuator is caused to produce a velocity as a function of the error signal. The gain of the closed force loop is selected so that the resonance of the mass-spring system has an effective damping ratio (.zeta.) greater than about 0.5, and preferably about 0.7. Thus, the mass-spring system will not be substantially resonantly excited by vibrations of the structure near its resonant frequency (.omega..sub.n).

    摘要: In a vehicle suspension system including a hydraulic actuator between a sprung mass consisting substantially of a vehicle body and an unsprung mass consisting substantially of a wheel, a force proportional to but opposite in phase to an inertia force acting on the unsprung mass is applied by the actuator to the unsprung mass so that the ability of the tire to maintain contact with the road surface may be improved. This produces very little effect on the behavior of the sprung mass, but the vehicle handling is significantly improved. Better contact with the road surface not only improves the vehicle handling but also reduces the consumption of energy by the hydraulic actuator. A particularly favorable result can be obtained when the hydraulic actuator further applies a damping force proportional to the absolute velocity of the sprung mass to the sprung mass.

    摘要: In an apparatus and method for controlling damping force characteristics of respective vehicular shock absorbers, a control signal V is generated according to a state in which a steering system is operated, the control signal being converted to a drive signal to be input to damping force characteristic changing member (stepping motor and adjuster) so that the damping force characteristic of the corresponding one of the shock absorbers is changed to a desired damping force characteristic. The control signal is a signal synthesized with a bounce rate signal based on a vertical sprung mass velocity signal, a roll rate signal determined on the basis of a difference between both right and left vertical sprung mass velocity signals, a roll rate (displacement) signal determined on the basis of the difference described above, a steering angular displacement signal, and a steering angular velocity signal at a predetermined rate of distribution .eta.. The predetermined rate of distribution (signal systhesis) is varied according to a vehicle speed.
