Abstract
L'invention concerne un procédé pour faire fonctionner un système (2), servant à détecter l'environnement d'un véhicule, qui comprend au moins un module émetteur/récepteur (4). Le module émetteur/récepteur (4) envoie un signal modulé en fréquence (26) et le module émetteur/récepteur (4) et/ou un ou plusieurs autres modules émetteurs/récepteurs (4) reçoivent des signaux d'écho (28) du signal modulé en fréquence (26) envoyé. Selon l'invention, les signaux d'écho reçus sont associés à des sources de réflexion (24) et les signaux d'écho (28) reçus permettent de déterminer une information concernant la vitesse relative (38) de la source de réflexion (24) par rapport au module émetteur/récepteur (4). L'invention concerne en outre un programme informatique ainsi qu'un système de détection d'environnement (2) qui sont adaptés en particulier pour mettre en œuvre le procédé selon l'invention.
