Abstract
An air spring suspension system includes first, second, third, and fourth air spring assemblies configured to support a frame of the vehicle at front and rear suspension/wheel assemblies of the vehicle. A valve block includes a valve. A compressor supplies pressurized gas to the valve block. A reservoir is in fluid communication with the valve block. The air spring suspension system includes first, second, third, and fourth height sensors. First, second, third, and fourth variable flow valves are in fluid communication with the valve of the valve block and the first, second, third, and fourth air spring assemblies, respectively. A pressure sensor senses pressure in the valve block. A vehicle kinematic sensor senses a vehicle kinematic parameter. A controller is configured to control the first, second, third, and fourth variable flow valves in response to the pressure, the first, second, third, and fourth height sensors, and the vehicle kinematic parameter.
