摘要： A temperature compensation method for controlling a damping force of a magnetorheological (MR) damper is disclosed. First, a base operating current as a function of a desired force level of a damping force of the MR damper is determined, and a temperature compensation as a function of an operating temperature of the MR damper is determined. Finally, the temperature compensation is applied to the base operating current to generate a compensated operating current as a function of the desired force level of the damping force and the operating temperature of the MR damper. To refine the compensated operating current, the temperature compensation can be determined as both a function of the operating temperature of the MR damper and a relative velocity of the MR damper.

摘要： A vehicle roll control system has a torsion bar and a first arm extending substantially perpendicular to the torsion bar. The first arm is fixed to the torsion bar at one end and connectable to one of the axles at the other end. A hydraulic actuator is attached to the torsion bar; and a control connected to the hydraulic actuator controls the operation thereof on detection of a predetermined vehicle condition. The hydraulic actuator comprises a housing, a piston making a sealing sliding fit inside the housing to define a first fluid chamber and a second fluid chamber, and a piston rod connected to the piston and extending through the second fluid chamber and out of the housing. The control acts on detection of the predetermined vehicle condition either to apply substantially the same fluid pressure to the first and second fluid chambers when the piston tends to move in a first direction to extend the hydraulic actuator or to apply a fluid pressure to the second fluid chamber above the fluid pressure in the first fluid chamber when the piston tends to move in a second direction to compress the hydraulic actuator. The first fluid chamber is fluidly connected to a fluid reservoir by the control when the piston tends to move in the second direction, and the control comprises a fluid pump and a directional valve, the pump being fluidly connected to the second fluid chamber and the directional valve being capable of moving between a first position in which the first fluid chamber and the second fluid chamber are fluidly connected, and a second position in which the first fluid chamber is fluidly connected to the fluid reservoir.
