Abstract
A method for controlling the storage pressure of a pressurized air store () of a closed level control system for a motor vehicle includes a compressor (), a pressurized air store () (which can be filled with air from the atmosphere and which can be discharged into the atmosphere) and at least one air spring (to). The air springs (to) are connected via the compressor () to the pressurized air store () so that pressurized air from the air springs (to) can be transferred into the pressurized air store () and can be transferred in the opposite direction. The storage pressure of the pressurized air store () is controlled indirectly via the air quantity in the level control system in that this air quantity is determined. The pressurized air store () is filled with air from the atmosphere when the air quantity lies below a lower limit and the pressurized air store () is discharged into the atmosphere when the air quantity lies above an upper limit. The control is undertaken in such a manner that the air quantity, after filling or discharging, lies in an operating range between the lower and upper limits.
