Abstract

L'invention concerne un procédé et un système de guidage d'espace de stationnement, comprenant les étapes suivantes : un système de guidage de stationnement interroge auprès d'une base de données un type d'espace de stationnement qui est pré-signalé par un terminal de communication et dans lequel un conducteur a stationné de manière appropriée, et interroge tous les espaces de stationnement libres qui correspondent au type d'espace de stationnement signalé par le terminal de communication et qui se trouvent à une distance spécifiée de la position actuelle du véhicule (202) ; le système de guidage de stationnement marque et transmet les positions de tous les espaces de stationnement libres interrogés au terminal de communication, de sorte qu'un conducteur d'un véhicule dans lequel se trouve le terminal de communication sélectionne un espace de stationnement libre cible parmi tous les espaces de stationnement libres en fonction des identifiants de position de tous les espaces de stationnement libres trouvés (203) ; et le système de guidage de stationnement génère un trajet de guidage d'espace de stationnement entre l'espace de stationnement libre cible et la position actuelle du véhicule et transmet celui-ci au terminal de communication pour un guidage vers l'espace de stationnement (204). La présente invention permet de trouver commodément un espace de stationnement qui répond aux compétences de conduite d'un conducteur et correspond au type de l'espace de stationnement, ce qui améliorer le taux d'utilisation d'espaces de stationnement.
