Abstract

A method for control of a pressurized air supply system for a motor vehicle. In a supply condition, the air compressor is driven by the drive motor and connected to a compressed air system of the motor vehicle such that compressed air is supplied to the compressed air system. In a non-supply condition, the compressor is not driven and/or connected to the compressed air system. The switching of the supply or non-supply condition results from a comparison of at least one switch pressure value with a pressure in the compressed air system and the topography of the stretch of road on which the vehicle is travelling, which includes the profile of the path which the vehicle must cover within a period of time and/or path distance to a given destination.
