Abstract
A closed leveling system for a vehicle includes a suspension system having a number of corners, and each corner includes at least one strut to be coupled to at least one wheel of the vehicle. The closed leveling system also includes a sensor and a master controller in communication with the sensor. The master controller includes a memory device including computer-readable instructions, and a processor in communication with the memory device. The leveling system also includes a power module assembly including a reservoir containing compressible liquid, a pump configured to withdraw the compressible liquid from the reservoir, a dump valve configured to transfer the compressible liquid into the reservoir, and isolation valves. Each isolation valve is associated with at least one corner. The leveling system further includes secondary volumes in selective fluid communication with the reservoir. Each secondary volume is associated with one isolation valve and at least one corner.
