Abstract
A controlling unit and a method of correcting an actual limit value of a sensor signal is described, wherein above or below the limit value a specific state of the sensor is recognized, the method comprises the steps of determining a new limit value of the sensor, determining a stability criteria to decide whether the actual limit value is corrected with said new limit value and approaching the actual limit value to the new limit value when the conditions are fulfilled to correct the actual limit value for said sensor.
Claims14
A method of correcting an actual limit value of a sensor signal, wherein above or below the limit value a specific state of the sensor is recognized, the method comprising:
- determining a new limit value of the sensor;
- determining a stability criteria to decide whether the actual limit value is corrected with the new limit value;
- and
- approaching the actual limit value to the new limit value when conditions are fulfilled to correct the actual limit value for the sensor.
A controlling unit for a sensor, wherein the controlling unit recognizes a specific state of the sensor if the sensor signal is above or below a limit value, the controlling unit comprising:
- an arrangement to determine a new limit value of the sensor;
- an arrangement to determine a stability criteria to decide whether the actual limit value is corrected with the new limit value;
- and
- an arrangement for approaching the actual limit value to the new limit value when conditions are fulfilled to correct the actual limit value for the sensor.
