Abstract
A method controls a compressor for delivering a pressure medium into a pressure medium system, for example an air suspension system in a motor vehicle. In the method, the delivery of the pressure medium can be switched on and off as a function of a temperature signal by the compressor temperature being measured by a temperature sensor which is arranged on the compressor and the switching on and off of the compressor is controlled by an electronic control unit. The switching-on time duration and/or the switching-off time duration or the switching-off and/or the switching-on temperature are/is determined from the rise of the compressor temperature which is measured at short time intervals.
Claims10
A method for controlling a compressor for delivering a pressure medium into a pressure medium system, which comprises the steps of:
- measuring a compressor temperature by means of a temperature sensor disposed on the compressor;
- switching on and off a delivery of the pressure medium in dependence on a temperature signal;
- controlling the switching on and off of the compressor by means of an electronic control unit;
- and
- determining at least one of an ON duration, an OFF duration, a switch-off temperature, and a switch-on temperature of the compressor from a gradient of the compressor temperature, which is measured at short time intervals.
A pressure medium system, comprising:
- a compressor;
- a temperature sensor disposed on said compressor;
- and
- an electronic control unit controlling at least one of an ON duration, an OFF duration, a switch-off temperature and a switch-on temperature of said compressor, said electronic control unit programmed to:
- measure a compressor temperature by means of said temperature sensor disposed on said compressor;
- switch on and off a delivery of a pressure medium in dependence on a temperature signal;
- control the switching on and off of said compressor by means of said electronic control unit;
- and
- determine at least one of the ON duration, the OFF duration, the switch-off temperature, and the switch-on temperature of said compressor from a gradient of the compressor temperature, which is measured at short time intervals.
A method of using an electronic control unit for a pressure medium system having a compressor for controlling at least one of an ON duration, an OFF duration, a switch-off temperature, and a switch-on temperature of the compressor, which comprises steps of:
- measuring a compressor temperature by means of a temperature sensor disposed on the compressor;
- switching on and off a delivery of a pressure medium in dependence on a temperature signal;
- controlling the switching on and off of the compressor by means of an electronic control unit;
- and
- determining at least one of the ON duration, the OFF duration, the switch-off temperature, and the switch-on temperature of the compressor from a gradient of the compressor temperature, which is measured at short time intervals.
