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.

Method for control of a pressurised air supply system for a motor vehicle

The invention involves a process for controlling the rotational speed of a drive motor during a start-up period, in a drive train, containing at least one starter element that can be coupled to the drive motor, in a rotationally fixed manner, in the form of a hydrodynamic coupling, containing a primary blade wheel and a secondary blade wheel, which form together at least one toroid-shaped working space. According to the invention, the rotational speed of the drive motor is set as a function of the power that can be consumed by the hydrodynamic coupling. The consumable power can be controlled or regulated.

Method for regulating the speed of a drive motor

A method for controlling the power consumption of a starting element () in the form of a hydrodynamic clutch (). The clutch comprises an impeller () and a turbine wheel (), which together form at least one toroidal working chamber () that can be filled with an operating medium, and is located in a drive train () with at least one other drive motor that can be coupled to the hydrodynamic clutch. The method is characterized in that the power consumption can be freely adjusted as a function of the volumetric efficiency of the hydrodynamic clutch and the method has the following characteristics: the supply or evacuation of the operating medium to or from the working chamber is influenced by the generation and introduction of a static superposition pressure in the closed rotating circuit; the operating medium is supplied or evacuated to or from the working chamber by the application of a superposition or influencing pressure to the operating medium level in the operating medium reservoir ().
