In a method for controlling the operation of a compressor, the compressor is switched off by a controller in order to prevent thermal damage if an estimated temperature value calculated by the controller exceeds an upper threshold value. The controller calculates a cooling function as a state variable utilizing the estimated temperature value, the cooling function representing the chronological course of the cooling of the compressor. The controller determines the cooling function based on at least one first and one second estimated temperature value which are associated with points of the compressor that are at spatial distances to each other. The calculation of the cooling function is based on a temperature difference between the first and second estimated temperature values.

Method for controlling the operation of a compressor

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.

Compressor temperature control by indirect temperature measurement

Motor vehicle having a closed ride height control system which contains a control unit in which a switch-off limiting value for at least one operating parameter of at least one component of the ride height control system is monitored, wherein in raising processes the activation of the component is prohibited or aborted when the switch-off limiting value is reached, and upward transgression of the switch-off limiting value of the operating parameter is permitted in the case of lowering processes.
