Abstract
A device, a sensor arrangement, a system and a method are provided for checking the plausibility of sensor data. The plausibility of the results of processing of sensor data is checked with an independent module by an alternative verification method at each stage, and quality indicators are calculated for the reliability of the calculated data from this plausibility check, which can be taken into account during further processing.
