Abstract
In order to simplify air flow control in a self-contained air supply system, an average control speed is calculated on the basis of a defined movement of the air springs (3, 4) and compared with an optimum control speed. The result of the comparison of the control speeds is used to determine the need for or the excess of an amount of compressed air. There are at least three possibilities for calculating the average control speed.

A method for controlling the quantity of air in a self-contained air supply system for a chassis, in which the demand for or the excess of a necessary quantity of compressed air for the air supply system is determined for a prescribed design case and is fed into the air supply system or let out of it over a defined time, comprising the following steps:
- calculating an average controlling speed from a defined movement of air springs (3, 4)′
- comparing the average controlling speed with an optimum controlling speed, and
- determining a demand for or an excess of a quantity of compressed air from the comparison between the two controlling speeds.
The method as claimed in claim 4, wherein the enclosed control space is embodied by a crank housing of a compressor (6) and an air drier (9) and the pressure in the control space is approximated to the atmosphere.
