Abstract

L'invention concerne un procédé de protection d'un usager de la route sans protection (10), un dispositif électronique (12), un procédé pour un véhicule automobile (16, 16') et un véhicule automobile (16, 16'). Une communication BT sans connexion d'un système radio d'un dispositif électronique (12) d'un usager de la route sans protection (10) avec d'autres usagers de la route (14) est utilisée pour déterminer une distance mutuelle sur la base des intensités de signal reçues des signaux de communication BT sans connexion. Si la distance déterminée de cette manière est inférieure à 15 m, un procédé de positionnement basé sur des mesures de temps de retard est effectué à l'aide de signaux UWB. Ceci permet de réaliser le procédé de positionnement basé sur UWB d'une manière plus ciblée, ce qui permet de réduire la consommation d'énergie et la charge sur des canaux radio locaux.
