Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Überprüfung mindestens eines Umfelderfassungssensors (1) eines Fahrzeugs (2). Erfindungsgemäß wird das Fahrzeug (2) in einer digitalen Karte lokalisiert, in der digitalen Karte werden Merkmale von hinterlegten stationären Objekten (3) einer Umgebung des Fahrzeugs (2) identifiziert, von denen erwartet wird, dass sie vom Umfelderfassungssensor (1) erkannt werden, und die Umgebung des Fahrzeugs (2) wird mit dem Umfelderfassungssensor (1) erfasst, wobei auf eine Degradation des Umfelderfassungssensors (1) geschlossen wird, wenn die erwartungsgemäß zu erkennenden Merkmale nicht vom Umfelderfassungssensor (1) erkannt werden oder wenn vom Umfelderfassungssensor (1) tatsächlich erkannte Merkmale von den erwartungsgemäß zu erkennenden Merkmalen stark abweichen.
(EN)
The invention relates to a method for checking at least one driving environment sensor (1) of a vehicle (2). According to the invention, the vehicle (2) is located on a digital map, features of stored stationary objects (3) in an environment of the vehicle (2), which are expected to be recognized by the driving environment sensor (1), are identified in the digital map and the environment of the vehicle (2) is sensed using the driving environment sensor (1), wherein a degradation of the driving environment sensor (1) is deduced if the features to be recognized according to expectations are not recognized by the driving environment sensor (1) or if features actually recognized by the driving environment sensor (1) deviate strongly from the features to be recognized according to expectations.
(FR)
L'invention concerne un procédé de contrôle d'au moins un capteur (1) de perception de l’environnement d'un véhicule (2). Selon l'invention, le véhicule (2) est localisé dans une carte numérique, dans laquelle des caractéristiques relatives à des objets fixes enregistrés (3) d'un environnement du véhicule (2) sont identifiées, caractéristiques dont il est attendu qu'elles soient reconnues par le capteur (1) de perception de l'environnement, et l'environnement du véhicule (2) est perçu au moyen du capteur (1) de perception de l’environnement. On en conclut à une dégradation du capteur (1) de perception de l'environnement si les caractéristiques à reconnaître conformément à ce qui est prévu ne sont pas reconnues par le capteur (1) de perception de l’environnement ou si des caractéristiques effectivement reconnues par le capteur (1) de perception de l’environnement diffèrent fortement de celles devant être reconnues conformément à ce qui est prévu.
