Definitions
- the invention relates to a method and a device for route guidance support of a driver to whom Instructions are given that result from a comparison of a by waypoint given route and each determined positions of the vehicle are derived.
- the computer is located in other known systems including the digital map base in the vehicle. This Systems are called on-board route guidance systems.
- the object of the present invention is that Presentation of information for the driver improve.
- the inventive method is for both on-board and also suitable for off-board systems.
- the latter is provided that data representing the specified route and describe the waypoints from a fixed computer transmitted to a vehicle unit located in the vehicle become.
- the guide points also symbols for from the guide points outgoing not on the specified route Roads included. It is advantageous if the symbols are short lines that differ from the connections between distinguish the waypoints.
- the method according to the invention can also be provided that furthermore a symbol for the position determined in each case of the vehicle is displayed.
- Document DE-A-4 219 326 relates to an in a vehicle built-in traffic information display system for displaying Card information for the driver.
- document WO-A-96 07 110 there is a Procedure for route guidance support of a driver specified where instructions are given that result from a comparison of a by way points of predetermined route and determined positions derived from the vehicle.
- Document EP-A-0 346 491 relates to a Method for route guidance support of a vehicle driver with a Direction arrow on the left under the traffic light; on the Complete maps are shown on the right side of the display.
- the device according to the invention is for Suitable for off-board systems.
- the latter is provided that data representing the specified route and describe the waypoints from a fixed computer transmitted to a vehicle unit located in the vehicle become.
- the representations of the guide points also Symbols for from the waypoints not on the included roads. It is advantageous if the symbols are short lines that stand out of the connections between the waypoints differentiate.
- the device according to the invention can also be used in this way be designed so that the respective waypoint to which the Vehicle arrives, including at least one Directional arrow can be represented schematically.
- Representation can either alternatively with the street map or can be switched on in addition to the road map, whereby the representation of the respective guide point Road at the waypoint, for example one Roundabout, reproduces.
- Figures 1 and 2 each show a screen 1 on which waypoints A, B, C, D and a destination Z according to their approximate geographic location including the paths connecting them. The latter are opposite at guidance points A to D branched paths highlighted.
- the vehicle is located apparently at the bottom of the picture and drives to the waypoint A to.
- a window 2 is a symbolic one Representation of waypoint A visible.
- the vehicle is now at the current time between waypoints A and B and is shown as symbol 4.
- On the way between the Waypoints C and D is a traffic jam on which by a symbol 5 is pointed out.
- Traffic calculator calculates an alternative route that is about further guidance points E, F leads to destination Z. The representation the alternative route is opposite the given route lifted.
- Embodiment of a device according to the invention consists of a vehicle unit 10 and a central one Device 11, between those with one each Transmitter / receiver 12, 13 there is a radio connection, for example according to the GSM standard.
- a traffic computer 14 In the central Device 11 is a traffic computer 14, the Has access to a stored road map 15 and for many vehicles perform the route determination.
- the vehicle unit 10 consists essentially of a On-board computer 16, a GPS receiver 17, one Input device 18, a display device 19 and a Memory 20. These components are known per se and do not need to be explained in more detail to understand the invention to become.
- the display device comprises a screen, for example in liquid crystal technology, on which the in the Figures 1 and 2 representations shown by way of example can be played.
- the GPS receiver 17 guides the on-board computer 16 continuously Information about the geographic position of the vehicle to. With the input device 18, the leader of the Enter a destination for the vehicle. This is together with the current position supplied to the traffic computer 14, the on the basis of the road map 15, the desired route is determined and on the vehicle unit 10 in the form of a guide point list transmits. Depending on the design of the invention In terms of procedure, the traffic computer also calculates the individual guidance points, as described above, Alternative routes that also lead to the vehicle unit are transmitted and also transmits traffic reports, that relate to the respective route.
- the position reports of the GPS receiver 17 will On-board computer communicated to what extent guidance points on the Desired route can be reached, so that the map Representations according to Figures 1 and 2 with the locomotion of the vehicle and the guidance information 2 (Fig. 1) for the respective leading guide point is shown.
