Abstract
A method for regulating a compressor of a pressure supplying system. The compressor is switched on and off dependent on a threshold temperature of one or more components of the pressure supplying system, the threshold temperature being ascertained using a temperature calculating method. The respective threshold temperature is ascertained by correlating the reciprocal temperature dependence that exists as a result of heat transfer between adjacent components.
Claims5
A method for regulating a compressor of a pressure supply system for a motor vehicle, wherein the compressor is driven by an electric motor and switched on and off in dependence on a limit temperature of one or more components of the pressure supply system ascertained with the aid of a temperature calculation method, wherein said limit temperature for switching the compressor on or off is ascertained using the temperature calculation method in dependence on one or more of the parameters:
- system pressure, ambient temperature, and running time of the compressor, the temperature of the component being ascertained by correlating the heat transfer between the component and an adjacent component,
- wherein the component is an O-ring of a compressor piston, the adjacent component is a cylinder tube of the compressor, and the limit temperature of the one or more components of the pressure supply system is the limit temperature of the O-ring, wherein the compressor is switched on and off in dependence on the limit temperature of the O-ring of the compressor piston, the temperature of the O-ring being ascertained by correlating the heat transfer between the cylinder tube of the compressor and the O-ring.
