Method and device for correcting the actual limit value of a sensor

摘要

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 including 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.

1. 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; deciding, based on the stability criteria, whether the actual limit value is corrected with the new limit value; and iteratively modifying the actual limit value to approach the new limit value responsive to a result of the deciding being that the actual limit value for the sensor is to be corrected with the new limit value.
