Abstract: An inflatable lift system for a vehicle includes N bladders arranged vertically in a stack, where N is an integer greater than two. N pressure sensors are configured to sense pressure in the N bladders, respectively. A compressor is configured to supply pressurized gas. N valves are configured to selectively connect and disconnect the N bladders to the compressor. A controller is configured to control the N valves to inflate the N bladders sequentially in a first predetermined order and to deflate the N bladders sequentially in reverse.
