IPC: G01S13/93
Filed: 2012-07-06
Abstract: La présente invention se rapporte à un système et à un procédé destinés à permettre à des véhicules de se suivre de près par le biais d'une automatisation partielle. Suivre un autre véhicule de près présente un avantage considérable en matière d'économies de carburant, mais est dangereux lorsque cela est fait manuellement par le conducteur. Sur l'extrémité opposée du spectre, des solutions totalement autonomes nécessitent une énorme quantité de technologie, et un niveau de solidité qui n'est actuellement pas rentable. Il est par conséquent évident qu'il existe un besoin urgent en matière de convoyage de véhicules semi-autonome fiable et économique. Ces systèmes de convoyage de véhicules semi-autonome améliorés permettent à des véhicules de se suivre de près d'une manière sécurisée, efficace et pratique.
