Title
(EN) DEVICE AND METHOD FOR DETERMINING A PHYSICAL QUANTITY
(FR) DISPOSITIF ET PROCÉDÉ POUR DÉTERMINER UNE QUANTITÉ PHYSIQUE
Abstract
(EN) 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.
(FR) La présente invention concerne un procédé et un dispositif pour déterminer une quantité physique à partir d'un nombre de valeurs mesurées qui contiennent des erreurs. Dans ledit procédé et ledit dispositif, tout d'abord, un groupement du nombre de valeurs mesurées qui contiennent des erreurs en une pluralité de sous-groupes de valeurs mesurées est exécuté, chaque sous-groupe comprenant une redondance, pour que davantage de valeurs mesurées par rapport au nombre de quantités mesurées soient contenues dans chaque sous-groupe. Ensuite, une quantité de fiabilité pour chaque sous-groupe est calculée en fonction de la redondance contenue dans le sous-groupe. Dans un procédé supplémentaire, une évidence individuelle est attribuée aux valeurs mesurées qui contiennent des erreurs de chaque sous-groupe en fonction de la quantité de fiabilité pour les sous-groupes respectifs. Un dispositif de détermination d'évidence détermine alors une évidence générale pour chaque valeur mesurée qui contient des erreurs en fonction des quantités d'évidence individuelle pour une valeur mesurée respective. Ensuite, un processeur calcule la quantité physique en utilisant au moins certaines des valeurs mesurées qui contiennent des erreurs et au moins certaines des évidences générales.
