(EN) CONDITION MONITORING OF A VEHICLE
(FR) SURVEILLANCE D'ÉTAT D'UN VÉHICULE
Abstract
(EN)
According to an aspect, there is provided a computer-implemented method for condition monitoring of a vehicle. The method comprises applying a dynamic model associated with a vehicle (800), the dynamic model having been determined by obtaining status information from at least one information bus of the vehicle, the status information providing real-time status information about the vehicle (200), obtaining, based on vehicle identity information, vehicle dynamics information (202), obtaining map data representing road characteristics of roads of a geographical area, the map data comprising two-dimensional road map data, three-dimensional road map associated with the roads, and road characteristics data (204), analyzing behavior of the vehicle based on the status information and the vehicle dynamics information (206), and computing a dynamic model for the vehicle by comparing the behavior of the vehicle to the map data (208); analyzing historical changes in at least one calibration parameter associated with the dynamic model of the vehicle (802); analyzing effects of the three- dimensional road map associated with the roads and the road characteristics data in at least one position on the behavior of the vehicle (804); and determining, based on the analyzed historical changes and the effects, at least one change in at least one vehicle characteristic (806).

Selon un aspect, l’invention concerne un procédé mis en œuvre par ordinateur pour surveiller l'état d'un véhicule. Le procédé consiste à appliquer un modèle dynamique associé à un véhicule (800), le modèle dynamique ayant été déterminé par l'obtention d'informations d'état à partir d'au moins un bus d'informations du véhicule, les informations d'état fournissant des informations d'état en temps réel concernant le véhicule (200), l'obtention, sur la base d'informations d'identité de véhicule, d'informations de dynamique de véhicule (202), l'obtention de données de carte représentant des caractéristiques de route des routes d'une zone géographique, les données de carte comprenant des données de carte routière bidimensionnelle, une carte routière tridimensionnelle associée aux routes, et des données de caractéristiques de route (204), l'analyse du comportement du véhicule sur la base des informations d'état et des informations de dynamique de véhicule (206), et le calcul d'un modèle dynamique pour le véhicule en comparant le comportement du véhicule avec les données de carte (208) ; l'analyse des changements historiques dans au moins un paramètre d'étalonnage associé au modèle dynamique du véhicule (802) ; l'analyse des effets de la carte routière tridimensionnelle associée aux routes et aux données de caractéristiques de route dans au moins une position sur le comportement du véhicule (804) ; et la détermination, sur la base des changements historiques analysés et des effets, d'au moins un changement dans au moins une caractéristique de véhicule (806).
