    Abstract: A bed height adjustment system for adjusting height of a bed of a vehicle including an air spring supporting the bed; a valve unit connected to an air tank and configured to adjust height of the air spring by supplying and discharging air; and a vehicle-control ECU provided with a dump-signal line and a return-signal line each connected to the valve unit. The valve unit adjusts the height of the air spring into a dump mode by inputting a signal of the dump-signal line, returns the height of the air spring into a normal mode by inputting a signal of the return-signal line, and maintains the dump mode or the normal mode when the signal is not input.

    Abstract: According to a method for controlling the air volume in a closed pneumatic spring system of a vehicle, an air-powered pump supplies at least two pneumatic springs and/or a compressed air reservoir with a specific air volume as needed such that the air pressure prevailing in the respective pneumatic spring and/or the compressed air reservoir is at a level which causes a vehicle body resting on the pneumatic spring to be positioned at a desired distance from the roadway or the vehicle axle. In order to obtain largely constant control velocities at different load conditions of the vehicle while using a smaller compressed air reservoir than in previously known systems, the pneumatic spring pressure (P) is measured in at least two of the pneumatic springs, the distance (HN, NN, TN) of the vehicle body to the roadway or the vehicle axle is determined, the axle load (AL) of at least one vehicle axle is determined from the pneumatic spring pressure (P) and the distance (HN, NN, TN) of the vehicle body to the roadway or the vehicle axle, a target system air volume (PV_SOLL) is determined in accordance with the respective axle load (AL), and the actual system air volume is adjusted to said target system air volume by actuating the air-powered pump or a relief valve.
