Method for correcting actual position of sensor parameter e.g. charge pressure sensor, for detecting pressure of gaseous or liquid medium in air system of motor car, involves correcting parameter by pressurizing with compensation parameter

The method involves pressurizing gaseous or liquid medium with pulsations of a predetermined frequency. A sensor parameter i.e. actual position (S-ist), is corrected by pressurizing with a separately generated periodical compensation parameter. The periodical compensation parameter is generated with...

Beschreibung
Zusammenfassung:	The method involves pressurizing gaseous or liquid medium with pulsations of a predetermined frequency. A sensor parameter i.e. actual position (S-ist), is corrected by pressurizing with a separately generated periodical compensation parameter. The periodical compensation parameter is generated with a frequency that corresponds to the predetermined frequency of the pulsations. The compensation parameter is generated by filtering out a disturbance parameter from the sensor parameter. Amplitude of the disturbance parameter is derived from an effective value of the disturbance parameter. Independent claims are also included for the following: (1) a method for operating a controller of an actuator for controlling flow of a gaseous or a liquid medium (2) a device for correcting a sensor parameter of a sensor (3) a device for operating a controller of an actuator for controlling flow of a gaseous or a liquid medium. Die Erfindung betrifft ein Verfahren zum Korrigieren einer Sensorgröße eines Sensors zum Erfassen einer Zustandsgröße eines gasförmigen oder flüssigen Mediums, insbesondere eines Sensors in einem Luftsystem eines Kraftfahrzeugs, wobei das gasförmige oder flüssige Medium mit Pulsationen einer vorgegebenen Frequenz beaufschlagt ist, wobei die Sensorgröße durch Beaufschlagen mit mindestens einer separat generierten periodischen Kompensationsgröße korrigiert wird.
