摘要： A method of controlling a vehicle suspension system for a vehicle body supported by a plurality of spaced apart wheels arranged in at least generally diagonally opposite pairs, the vehicle suspension system including an adjustment system for adjusting the position of each of the wheel rams relative to the vehicle body, sensors adapted to generate a signal indicative of the position of each of the wheels, an electronic control unit arranged to receive the signals, wherein the required position for each wheel ram is determined as a function of the diagonal average of the positions of each pair of diagonally opposite wheels, the position of each wheel being adjusted on the basis of the diagonal averages.

摘要： A vehicle suspension control system that allows substantially vertical motion of each wheel relative to the vehicle body includes front and rear resilient support means for supporting the body, a front roll stabilization assembly interconnecting at least one forward pair of wheels and a rear roll stabilization assembly interconnecting at least one rearward pair of wheels. Each roll stabilization assembly includes at least one lateral torsion bar (2) and a double-acting hydraulic actuator (3) interconnected to the at least one lateral torsion bar (2), the front and rear hydraulic actuators (3) being interconnected by first and second fluid conduits (5). Roll moments applied to the vehicle body generate pressure within the fluid conduits (5) thereby transmitting the roll moment into each lateral torsion bar (2). Warp motions of the wheels generate flow along the fluid conduits (5) resulting in a displacement of one hydraulic actuator (3) in a proportional and opposite direction to the other hydraulic actuator (3). The front and rear roll stabilization assemblies provide roll stiffness during both roll and warp motions while at the same time providing substantially zero warp stiffness. The system includes an hydraulic fluid supply means (12) and fluid conduit valve means (13) for selectively communicating the fluid conduits (5) with the hydraulic fluid supply means (12) to regulate the average pressure in both fluid conduits (5).
