Patent attributes
A vehicle fluid suspension control system includes a fluid supply adapted to fluidly communicate with a lift mechanism in the vehicle. A circuit board is connected to the fluid supply and exhausts fluid from the lift mechanism when the kneel switch is activated. The circuit board may also open a flowpath from the fluid supply to the lift mechanism when a kneel switch is deactivated and the brake pedal is depressed. A manifold may be in fluid communication with the fluid supply and the lift mechanism and may include a supply flowpath and an exhaust flowpath. The control system may be programmed with a height averaging adjustment delay, which determines whether the average height of the vehicle during a period of time is outside of a predetermined range. The control system may make corresponding adjustments to bring the height of the vehicle within the predetermined range.
