Abstract[English]
Provided is a method for monitoring a time distribution via a network switch to be used in a communication network of an automated vehicle. The method comprises receiving, a first synchronized time, at a first port of the network switch, receiving, a second synchronized time, at a second port of the network switch, comparing the received first synchronized time to the received second synchronized time, and output a control signal if a result of the comparing is that a difference between the received first synchronized time and the received second synchronized time exceeds a predefined threshold.[French]
L'invention concerne un procédé de surveillance d'une distribution de temps par l'intermédiaire d'un commutateur de réseau à utiliser dans un réseau de communication d'un véhicule automatisé. Le procédé comprend recevoir, un premier temps synchronisé, au niveau d'un premier port du commutateur de réseau, recevoir, un second temps synchronisé, au niveau d'un second port du commutateur de réseau, à comparer le premier temps synchronisé reçu au second temps synchronisé reçu, et délivrer en sortie un signal de commande si un résultat de la comparaison est qu'une différence entre le premier temps synchronisé reçu et le second temps synchronisé reçu dépasse un seuil prédéfini.
