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, grouping of the number of measured values containing errors into a plurality of subgroups of measured values is executed, wherein each subgroup includes 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. Further, 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 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.

1. A device for determining a physical quantity from a number of measured values comprising errors, wherein the physical quantity is defined by a measured quantity or a plurality of measured quantities, and wherein the number of the measured values is higher than the number of the measured quantities, comprising:
a grouper for grouping the number of measured values comprising errors into a plurality of subgroups of measured values, wherein each subgroup comprises a redundancy, so that each subgroup includes a number of measured values, the number of measured values being greater than a number of measured quantities; a calculator for calculating a reliability quantity for each subgroup based on the redundancy comprised in the subgroup; an individual allocator for allocating individual evidence quantities to the measured values comprising errors of each subgroup based on the reliability quantity for the respective subgroups, so that a respective measured value has a plurality of individual evidence quantities allocated thereto; an evidence determiner for determining one overall evidence each for the measured values comprising errors based on the plurality of individual evidence quantities for the respective measured value; and a processor for calculating the physical quantity using at least some of the measured values comprising errors and at least some of the overall evidences.
