Abstract
A method for compensating the offset of a pressure value having the steps: detecting a pressure value, lowpass filtering of the pressure value, storing the lowpass filtered pressure value as an offset value, the lowpass filtered pressure value being stored as an offset value if at least the condition is present that a logical signal has or assumes a first value and a substitute value is stored as an offset value if the logical signal has or assumes a second value. Also described herein is a device for compensating the offset of a pressure value.
Claims13
A method to compensate an offset of a pressure value, comprising the steps of:
- detecting a pressure value;
- performing a lowpass filtering of the pressure value;
- storing the lowpass filtered pressure value as a first offset value if at least a logical signal is a first value;
- and
- storing a substitute value as another offset value if the logical signal is a second value.
A device for compensating an offset of a pressure value, comprising:
- an arrangement for detecting a pressure value;
- an arrangement for performing a lowp ass filtering of the pressure value;
- and
- an arrangement for storing the lowpass filtered pressure value as a first offset value if at least a logical signal is a first value, and for storing a substitute value as another offset value if the logical signal is a second value.
