    摘要： An apparatus and method for controlling damping force characteristics of shock absorbers independently of one another, the damping force coefficient for each shock absorber being controlled on the basis of so-called "sky hook" theory with respective sprung mass vertical velocities and relative velocities between the sprung mass and unsprung mass taken into consideration. The relative velocity detecting sensors are only installed on portions of the vehicle related to front left and right tire wheels. The road surface velocities on the front left and right tire wheels are calculated and the road surface velocities on the rear left and right tire wheels are calculated on the basis of the calculated front left and right wheel road surface velocities, a vehicular wheel base length, and a vehicle speed. Then, relative velocities between the sprung mass and unsprung mass related to the rear left and right tire wheels are calculated on the basis of the calculated rear left and right tire wheel road surface velocities and sprung mass vertical velocities related to the vicinities of the rear left and right tire wheels.

    摘要： The invention relates to an active wheel supporting system for vehicles having a scanning device which registers surface unevenness in a roadway, and active wheel support assemblies which are controlled by the scanning device so that the wheels are actively adjusted to the registered surface unevenness. To avoid acceleration of the vehicle body, wheel support assemblies are coupled in each case to counter-masses which carry out movements opposite to the wheel movements relative to the vehicle body. The reaction forces exerted on the body by the wheel movements are thus compensated by reaction forces directed in the opposite direction due to the simultaneous movement of the counter-masses.

    摘要： An adaptive active suspension system for a wheeled vehicle in which a powered actuator supplies a force between an unsprung wheel assembly and the vehicle body. The actuator is controlled by a signal from a feedback control system whose dynamic properties are determined by control gain values stored in a memory. The stored control gain values are calculated to simultaneously reduce vehicle body acceleration, tire deflection and suspension displacement (stroke). A road profile estimator provides an indication of predicted road roughness and, as road roughness varies, the effective stiffness of the suspension system is adaptively altered while maintaining a substantially constant ratio between tire deflection and suspension stroke. To reduce the computational burden on the system, the control gains are pre-computed for a range of varying road conditions and stored in memory. The current control gains in effect may be updated on a substantially continuous basis or, to further reduce the amount of computing required, may be altered only when the current estimate of road roughness departs from a predetermined range of values.

    摘要： An active suspension apparatus is provided for a vehicle which includes an actuator being extensible and retractable and provided between a vehicle body and a wheel so that the force of the vehicle body to support the wheel is adjustable, a sprung G sensor or a vehicle height sensor for detecting a vibration input to the vehicle body, and a control valve and a controller for controlling the supporting force of the actuator in accordance with the vibration input detected by the sprung G sensor or the vehicle height sensor, and thereby restraining the stroke of the actuator. The suspension apparatus further comprises a forward road surface sensor for detecting the size of irregularities of a road surface in front of the vehicle, and the control valve and the controller are adapted to execute normal control such that the equivalent spring constant of the actuator is adjusted to a first spring constant when a surface irregularity of a size larger than a predetermined size is detected by the forward road surface sensor, and to execute inverse spring control such that the equivalent spring constant of the actuator is adjusted to a second spring constant lower than the first spring constant, and thereby lengthening the stroke of the wheel, when no surface irregularity of a size larger than the predetermined size is detected by the forward road surface sensor. As a result, the ride is greatly improved when the vehicle runs on a smooth road.

    摘要： In a suspension system for a vehicle comprising a shock absorber of which damping force characteristics can be changed into four or more characteristics, detecting means detect the oscillation frequency range of the sprung member of the vehicle and a bumpy road. From the four or more damping force characteristics of the shock absorber, the number of characteristics on the higher level side are limited to two or so when the sprung member is in a low frequency oscillation range, that of the characteristics on the lower level side are limited to two or so when the sprung member is in a high frequency oscillation range, and that of the characteristics on the medium level side are limited to two or so when a road is bumpy. The damping force characteristic of the shock absorber is selected and changed on the basis of a given control rule only within the limited damping force characteristics. Thus, it is possible to prevent noise and oscillation from being caused by the large change of the damping force characteristic. Furthermore, there can be obtained comfortableness to ride in and stability on a high level.
