Title
(EN) ON-BOARD VEHICLE STOP CAUSE DETERMINATION SYSTEM
(FR) SYSTÈME EMBARQUÉ DE DÉTERMINATION DE CAUSE D'ARRÊT DE VÉHICULE
Abstract
(EN)
A vehicle can include an on-board data processing system that receives velocity data captured by one or more sensors of the vehicle. As a vehicle travels along a route, the on-board data processing system can process the velocity data to identify potential vehicle stops. For example, the system can detect a trough in velocity values, and determine whether a velocity value at the trough is below a threshold velocity value. If the velocity value is below the threshold velocity value, the system can determine whether any vehicle stops were previously detected within a threshold time of the time corresponding to the trough. If a vehicle stop was previously detected, the system may detect that a stop occurred at the time of the trough if the velocity of the vehicle increased by at least a velocity ripple value between the time of the previously-detected stop and the time of the trough.

La présente invention concerne un véhicule pouvant comprendre un système de traitement de données embarqué qui reçoit des données de vitesse capturées par un ou plusieurs capteurs du véhicule. Lorsqu'un véhicule se déplace le long d'un itinéraire, le système de traitement de données embarqué peut traiter les données de vitesse pour identifier les arrêts potentiels du véhicule. Par exemple, le système peut détecter un creux dans des valeurs de vitesse, et déterminer si une valeur de vitesse au niveau du creux est inférieure à une valeur de vitesse seuil. Si la valeur de vitesse est inférieure à la valeur de vitesse seuil, le système peut déterminer si des arrêts de véhicule quelconques ont été précédemment détectés à l'intérieur d'un temps seuil du temps correspondant au creux. Si un arrêt de véhicule a été précédemment détecté, le système peut détecter qu'un arrêt s'est produit au moment du creux si la vitesse du véhicule augmentée par au moins une valeur d'ondulation de vitesse entre le temps de l'arrêt précédemment détecté et le temps du creux.
