Abstract
A sensor system includes a plurality of sensor elements and a signal processing device. The plurality of sensor elements detect at least in part different primary measurement variables and utilize at least in part different measurement principles. The signal processing device is configured to evaluate the sensor signals of the sensor elements.
Claims20
A sensor system, the sensor system comprising:
- a plurality of sensor elements configured to detect at least in part different primary measurement variables and utilize at least in part different measurement principles,
- a signal processing device,
- wherein the signal processing device is configured to evaluate the sensor signals of the sensor elements,
- wherein the signal processing device has a fusion filter which provides a defined fusion data set in the course of the evaluation of at least the sensor signals and/or signals derived therefrom of the sensor elements,
- wherein said fusion data set has in each case data with respect to defined physical variables, wherein the fusion data set comprises, with respect to at least one physical variable, a value of said physical variable and information about the data quality thereof.
2 more elements
The sensor system wherein the fusion filter is a Kalman filter which iteratively carries out at least prediction steps and correction steps and provides at least in part the fusion data set.
