DEVICE AND METHOD FOR DETERMINING A PHYSICAL QUANTITY

摘要

In a method and a device for determining a physical quantity from a number of measured values containing errors, first of all a grouping of the number of measured values containing errors into a plurality of subgroups of measured values is executed, wherein each subgroup comprises a redundancy, so that more measured values than the number of measured quantities are contained in each subgroup. Hereupon, a reliability quantity for each subgroup is calculated based on the redundancy contained in the subgroup. In a further process an individual evidence is allocated to the measured values containing errors of each subgroup based on the reliability quantity for the respective subgroups. An evidence determiner then determines one overall evidence each for each measured value containing errors based on the individual evidence quantities for a respective measured value. Hereupon, a processor calculates the physical quantity using at least some of the measured values containing errors and at least some of the overall evidences.
