Abstract: A vehicle having a body (25) supported respective pairs of front and rear wheels (30, 31, 32, 33), two piston and cylinder units (23-24, 35-36, 37-38, 34-39) being associated with each wheel and connected between the wheel (30) and body (25) so the piston moves in the cylinders in response to relative movement between the wheel and the body. An individual fluid circuit (40, 41, 42, 43) connecting one piston and cylinder unit (23) of each wheel (30) to a corresponding unit (34) longitudinally spaced therefrom on the same side of the vehicle, and the other piston and cylinder unit (24) of each wheel to a corresponding unit (35) on the transversely opposite side of the vehicle. This arrangement results in the fluid pressure in any two piston and cylinder units interconnected by an individual fluid circuit being equal, and relative movement between any one wheel and the vehicle body induces an opposite relative movement between the vehicle body an the wheel in fluid circuit therewith to maintain tractive ground engagement of all wheels.

Abstract: A suspension system and associated control methods for improving the effectiveness of driver assistance systems is disclosed where the driver assistance systems can generate and send requests to a suspension control unit (SCU) of the suspension system to actuate (e.g., close) one or more comfort valves in the suspension system to increase the roll stiffness and/or pitch stiffness of the suspension system when the driver assistance systems are taking corrective action. As part of a two-way communication between the suspension control unit (SCU) and the driver assistance systems, the suspension control unit (SCU) communicates target stiffnesses and/or calculated effective stiffnesses to the driver assistance systems, which is used to update the vehicle stability models used by the driver assistance systems.
