Abstract:
A method of improving quality of actuator motion in a vehicle active tilt control system having front and rear stabilizer bars torsionally adjusted by front and rear actuators, respectively, wherein the actuators are movable between first and second opposing fully stroked positions via pressurized fluid which is pumped through a directional control valve to the actuators, the method comprising:precharging a single accumulator to a predetermined pressure level less than a pressure needed to move the actuators between the first and second fully stroked positions;providing said single accumulator in a normally open condition in fluid communication with the pumped, pressurized fluid between the directional control valve and the actuators; anddecelerating the actuators near the fully stroked positions by communicating said single accumulator with the pumped, pressurized fluid when fluid pressure of the pressurized fluid overcomes the precharged predetermined pressure level in the accumulator prior to the actuators reaching their respective fully stroked positions in order to cushion actuator movement near the fully stroked positions.
