Title
(EN) METHOD OF VEHICLE LOCALIZATION USING PASSIVE ROADWAY DETECTION DURING A MINIMUM RISK MANEUVER
(FR) PROCÉDÉ DE LOCALISATION DE VÉHICULE UTILISANT UNE DÉTECTION PASSIVE DE CHAUSSÉE PENDANT UNE MANOEUVRE DE RISQUE MINIMALE
Abstract
(EN)
A method of detecting a roadway shoulder in an at least partially autonomous vehicle, during a minimum risk maneuver, comprising sensing a vibration within a vehicle, identifying a frequency of the vibration, and determining whether the vehicle is in contact with rumble strips in response to the identified frequency, when at least one or more sensors in a typical known sensor system is compromised.
(FR)
L'invention concerne un procédé de détection d'un accotement de chaussée dans un véhicule au moins partiellement autonome, pendant une manoeuvre de risque minimale, comprenant la détection d'une vibration à l'intérieur d'un véhicule, l'identification d'une fréquence de la vibration, et la détermination du fait que le véhicule est en contact ou non avec des bandes rugueuses en réponse à la fréquence identifiée, lorsqu'au moins un ou plusieurs capteurs dans un système de capteurs connu habituel est compromis.
