  • the signals that have been received at the data port 499 can be used by the arrangement 400 to determine whether the said motor vehicle 100 is to be allowed to be driven autonomously and/or externally, or to be prevented from being driven autonomously and/or externally.
  • Parts of the methods described here may be carried out by the arrangement 400 with the aid of the data processing unit 410, which runs the program stored in the memory 460 or in the read/write memory 450.
  • the arrangement 400 runs the program, the method described here is executed.

Abstract

L'invention concerne un système (200) pour permettre le fonctionnement autonome et/ou la commande externe d'un véhicule à moteur, comprenant un système de commande externe (205) servant à générer un signal (S1) comprenant au moins un paramètre de commande pour la commande dudit véhicule à moteur, et un système de commande (270) qui est interne au véhicule, comprenant une unité de commande (220). Au niveau du système (200), une interface informatique (210) est agencée en liaison communicante avec le système de commande externe (205) et le système de commande (270) qui est interne au véhicule, l'interface informatique (210) servant à transférer le signal (S1) du système de commande externe (205) au système de commande (270) qui est interne au véhicule. Ladite unité de commande (220) sert à déterminer si une condition préétablie prévaut au niveau dudit véhicule à moteur (100) afin de permettre l'initiation du fonctionnement autonome et/ou de la commande externe, la condition préétablie au niveau dudit véhicule à moteur (100) comprenant le fait que le véhicule à moteur (100) est stationnaire. L'invention concerne également un procédé permettant le fonctionnement autonome et/ou la commande externe d'un véhicule à moteur et un véhicule à moteur (100, 110) comprenant un tel système (200).
