Title (EN) IMPROVED NAVIGATION FOR A VEHICLE BY IMPLEMENTING TWO OPERATING MODES
(FR) NAVIGATION AMÉLIORÉE POUR VÉHICULE PAR LA MISE EN ŒUVRE DE DEUX MODES DE FONCTIONNEMENT
Abstract:
(EN) A robotic lawnmower (100) for movable operation within a work area (205) has a satellite navigation device (190), a landmark scanner (193) and a controller (110). The controller causes the robotic lawnmower (100) to movably operate within the work area (205) in a first operating mode, the first operating mode being based on positions determined from satellite signals received by the satellite navigation device (190). The controller determines that a position cannot be reliably determined based on satellite signals received by the satellite navigation device (190), and in response thereto causes the robotic lawnmower (100) to movably operate within the work area (205) in a second operating mode. In the second operating mode, the controller receives scanning information from said landmark scanner (193) and identifies at least one landmark based on the received scanning information and determines a landmark-based position estimate. The controller defines a search space using the landmark-based position estimate, and the satellite navigation device (190) is reconstructed based on the defined search space. Once the satellite navigation device (190) has been reconstructed, the controller causes the robotic lawnmower (100) to again operate in the first operating mode.
(FR) L’invention concerne une tondeuse à gazon robotisée (100) destinée à fonctionner de façon mobile à l'intérieur d'une zone de travail (205) possédant un dispositif de navigation par satellite (190), un scanner de repère (193) et un organe de commande (110). L’organe de commande amène la tondeuse à gazon robotisée (100) à fonctionner de façon mobile à l'intérieur de la zone de travail (205) dans un premier mode de fonctionnement, le premier mode de fonctionnement étant basé sur des positions établies à partir de signaux satellite reçus par le dispositif de navigation par satellite (190). L’organe de commande établit qu'une position ne peut pas être établie de manière fiable sur la base des signaux satellite reçus par le dispositif de navigation par satellite (190), et, en réponse à ceci, amène la tondeuse à gazon robotisée (100) à fonctionner de façon mobile à l'intérieur de la zone de travail (205) dans un second mode de fonctionnement. Dans le second mode de fonctionnement, l'organe de commande reçoit des informations de balayage en provenance dudit scanner de repère (193) et identifie au moins un point de repère sur la base des informations de balayage reçues et détermine une estimation de position en fonction du point de repère. L'organe de commande établit un espace de recherche au moyen de l'estimation de position en fonction du point de repère, et le dispositif de navigation par satellite (190) est réétalonné sur la base de l'espace de recherche établi. Une fois le dispositif de navigation par satellite (190) réétalonné, l'organe de commande amène la tondeuse à gazon robotisée (100) à fonctionner de nouveau dans le premier mode de fonctionnement.
