Definitions

  • the invention relates to a method and a device for route guidance support of a vehicle driver, on which instructions are issued which are derived from a comparison of a route predefined by route guidance points and respectively determined positions of the vehicle.
  • the computer including the digital map base, is located in the vehicle. These systems are called on-board route guidance systems.
  • the route information is transmitted to the driver in the form of symbolized representations of the route points, in particular the intersections and branches.
  • the driver lacks any information about the subsequent course of the route. He must therefore have complete trust in the functionality of the system. Furthermore, an inaccurate position determination of the vehicle or a complicated course of the road can lead the driver to make rapid lane changes.
  • the object of the present invention is to improve the information display for the vehicle driver.
  • the route guide points and connections between the route guide points of at least a part of the predetermined route are shown schematically.
  • the display can be such that only the part of the route lying in front of the vehicle or only part of it is shown.
  • the respective position of the vehicle is then at the bottom of the display, while the representation of the route and the guidance points are moved in accordance with the vehicle movement.
  • the method according to the invention is suitable for both on-board and off-board systems.
  • data representing the specified route and describe the way points are transmitted from a fixed computer to a vehicle unit in the vehicle.
  • the representations of the guide points also contain symbols for roads which do not lie on the specified guideway and which depart from the guide points. It is advantageous if the symbols are short lines that differ from the connections between the waypoints.
  • the method according to the invention can also provide that a symbol for the respectively determined position of the vehicle is also shown.
  • a further development of the method according to the invention consists in that data about the traffic conditions are also transmitted and displayed in the form of the respective waypoint points and / or the symbols assigned between the waypoint points.
  • This data can, for example, traffic obstacles such as traffic jams, closures or affect the weather.
  • Route guidance support for a vehicle driver with a graphical display device (display) for outputting instructions which are derived from a comparison of a route specified by waypoint points and the positions of the vehicle determined in each case, is characterized in that the waypoint points and connections between the waypoint points of at least part of the predetermined amount Driving paths are shown schematically.
  • the device according to the invention is suitable for both on-board and off-board systems.
  • data describing the predefined route and the guidance points are transmitted from a stationary computer to a vehicle unit located in the vehicle.
  • the representations of the guide points also contain symbols for roads that start from the guide points and do not lie on the predefined route. It is advantageous if the symbols are short lines that differ from the connections between the waypoints.
  • the device according to the invention can also be designed such that the respective guide point to which the vehicle is traveling, including at least one directional arrow, can be represented schematically.

Abstract

L'invention concerne un procédé pour l'assistance à la navigation d'un conducteur de véhicule auquel sont données des instructions qui sont dérivées d'une comparaison entre un trajet prédéterminé par des points de guidage de déplacement et des positions respectives déterminées du véhicule. Selon ledit procédé, des points de guidage de déplacement et les liaisons entre les points de guidage de déplacement d'au moins une partie de l'itinéraire prédéterminé sont représentés schématiquement.
