Abstract
Apparatus for controlling and adjusting an arbitrary number of adjustment units for a motor vehicle includes an electro-pneumatic bus to which are connected in arbitrary sequence, both electrically and pneumatically, all the pertinent adjusting units. The electro-pneumatic bus is composed of at least one pneumatic adjustment pressure line and of at least one electric control signal line which may contain several conductors. While reference data from a central control electronics are applied through the electric control signal line of the electro-pneumatic bus, the individual adjusting units are connected through associated valves in the pneumatic system to the pneumatic adjustment pressure line of the electro-pneumatic bus. The adjusting units preferably are designed to be modular control loops. As a result the pneumatically driven adjusting members units not only two positions, but also they may be set and controlled in quasi-analogue manner.
