    摘要: Method and device for calculating chassis height of a vehicle that has at least three air-suspended wheel axles (2, 3, 4). The device includes a control unit and two level sensors (9, 10). The control unit detects the chassis height at the front axle (2) via a first level sensor (9) and at the forward rear axle (3) via a second level sensor (10), and the control unit calculates the chassis height at the rearmost wheel axle (4). An object of the disclosure is to protect the rear axle installation with as few level sensors as possible.

    摘要: A method and system for controlling a vehicle suspension system switchable between two modes of operation, including a first mode for when the vehicle is experiencing an on-road driving condition and a second mode for when the vehicle is experiencing an off-road driving condition, includes a vehicle speed sensor for sensing a speed of the vehicle and generating a vehicle speed signal, which may be an inherent part of the vehicle required for other vehicle functions, such as ABS, speed, or other control. The system also includes a controller for detecting an off-road driving condition and comparing the vehicle speed signal to a predetermined speed threshold. The controller then controls the suspension system to switch to the second mode of operation upon detecting the off-road driving condition and the vehicle speed signal being less than the predetermined speed threshold.

    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: Deflection detection pick-ups are arranged at the wheels or wheel suspensions of the vehicle, from the signals of which pick-ups a computer determines an averaged pitch angle. These averaged actual values are compared with predetermined or predeterminable set values. the correction of the supporting forces of the support assemblies effected thereupon by the computer is dependent on the extent to which the vehicle body has to execute pure lifting movements, pure rolling movements and/or pure pitching movements to approximate the actual values to the set values and in which proportions the forces necessary for the damping of rolling or pitching movements are to be applied by the support assemblies of the front or rear wheels. In this case, the forces serving for the compensation of rolling movements can be distributed over the front and rear wheels in such a way that a desired control tendency of the vehicle, in particular a tendency toward under-controlling, is obtained.
