Abstract

L'invention concerne un système de commande conçu et défini pour être utilisé dans un véhicule à moteur, lequel système détermine, sur la base de données de champ environnant obtenues d'un ou de plusieurs capteurs périphériques situés sur le véhicule à moteur, un moment à partir duquel un changement de voie peut être effectué en toute sécurité lorsqu'il s'agit de passer d'une voie de dépassement à une voie de circulation plus lente située à côté. Les capteurs périphériques sont conçus pour fournir à une commande électronique du système de commande les données de champ environnant représentant la zone située latéralement devant le véhicule, latéralement à côté du véhicule et/ou latéralement derrière celui-ci. Le système de commande est au moins conçu et défini pour déterminer, pendant un laps de temps prédéfini ou en continu, dans la commande électronique, des données de roulage représentant la situation de roulage dudit véhicule à moteur à partir d'émetteurs de signaux présents dans celui-ci. Pendant le laps de temps prédéfini ou en continu, un ou plusieurs autres véhicules prennant part au trafic et situés latéralement devant le véhicule à moteur, latéralement à côté du véhicule à moteur et/ou latéralement derrière celui-ci sont détectés par les capteurs périphériques en vue de déterminer des grandeurs caractéristiques relatives à la situation/aux situations de roulage de cet autre véhicule/de ces autres véhicules. Sur la base des données de roulage représentant la situation de roulage du véhicule équipé dudit système ainsi que des grandeurs caractéristiques relatives à la situation/aux situations de roulage de l'autre véhicule/des autres véhicules, le système détermine si cet autre véhicule/ces autres véhicules ne se trouve pas/ne se trouvent pas dans une zone critique sur le plan de la sécurité située latéralement à côté du véhicule équipé du système et/ou latéralement derrière celui-ci et cette information est délivrée au conducteur dudit véhicule par voie optique, haptique et/ou acoustique. À cet effet, le système de commande est conçu et défini pour déterminer, dans la commande électronique, sur la base des données de roulage représentant la situation de roulage du véhicule équipé du système ainsi que des grandeurs caractéristiques relatives à la situation/aux situations de roulage de l'autre véhicule/des autres véhicules, le moment à partir duquel le changement de voie peut être effectué en toute sécurité. Ce moment est considéré comme étant arrivé lorsque la commande électronique détermine qu'un bord de fuite du véhicule à moteur équipé du système a passé un bord d'attaque de l'autre véhicule ainsi qu'une distance de sécurité adaptée aux conditions légales et/ou physiques.
