Abstract

The invention relates to a method of vehicle navigation using a road map shown on a display. According to said method, at the start of a journey the vehicle position is determined and its destination entered so that a road map is displayed whose scale is such that it shows both the position of the vehicle and its destination. As the vehicle approaches its destination in the course of the journey the scale of the map is automatically enlarged in such a way that the size of the display is at all times fully utilized and the destination and position of the vehicle at any given time can always be identified on the road map.

Description

Beschreibung description
Verfahren zur FahrzeugnavigationVehicle navigation procedures
Die Erfindung betrifft ein Verfahren zur Fahrzeug-Navigation mittels einer auf einem Display angezeigten Straßenkarte des jeweiligen Fahrgebietes und einer Zoomeinrichtung zur Vergrößerung des Maßstabes der Straßenkarte.The invention relates to a method for vehicle navigation by means of a road map of the respective driving area shown on a display and a zoom device for increasing the scale of the road map.
Heutige Kraftfahrzeuge haben teilweise bereits eine Fahrzeug-Navigation, welche mit einem solchen Verfahren arbeitet. Dabei wird die jeweilige Fahrzeugposition automatisch durch ein Satelliten-Navigationssystem bestimmt, während bei Fahrtbeginn der Fahrer von Hand das Fahrziel eingibt. Nach der Eingabe des Fahrziels erscheint auf dem Display eine Straßenkarte, welche das gesamte Fahrgebiet zwischen dem Startpunkt und dem Fahrziel zeigt. Bei einer größeren Fahrstrecke muss der Maßstab dieser dargestellten Straßenkarte klein sein, damit die Straßenkarte das gesamte Fahrgebiet auf dem Display zeigen kann. Deshalb können in solchen Fällen keine Details gezeigt werden. Will man diese wissen, dann betätigt man eine Zoomeinrichtung, und erhält dadurch von dem Gebiet, in dem man sich gerade befindet, eine detaillierte Darstellung, die jedoch aufgrund des großen Maßstabes meist das Fahrziel nicht mehr zeigt, so dass man das Fahrziel im wörtlichen Sinne aus dem Auge verliert. Deshalb muss man nach der Betätigung der Zoomeinrichtung wieder zurück auf den ursprünglichen Kartenmaßstab schalten, damit man das Fahrziel wieder finden kann. Das vorübergehende Zoomen der Straßenkarte lenkt jedoch den Fahrzeugführer unerwünscht lang von der Beobachtung des Verkehrsgeschehens ab, so dass von dieser Möglichkeit eigentlich nur bei einem Fahrzeugstillstand Gebrauch gemacht werden sollte. Der Erfindung liegt das Problem zugrunde, ein Verfahren zur Fahrzeugnavigation zu entwickeln, welches während der gesamten Fahrt eine Darstellung der Straßenkarte in einem möglichst großen Maßstab ermöglicht, ohne dass das Erfordernis eines manuellen Umschaltens des Kartenmaßstabes besteht.Today's motor vehicles already partially have vehicle navigation that works with such a method. The respective vehicle position is automatically determined by a satellite navigation system, while the driver manually enters the destination when the journey begins. After entering the destination, a road map appears on the display, showing the entire driving area between the starting point and the destination. In the case of a longer route, the scale of the road map shown must be small so that the road map can show the entire driving area on the display. Therefore, no details can be shown in such cases. If you want to know this, you operate a zoom device, and this gives you a detailed representation of the area in which you are currently located, but due to the large scale it usually no longer shows the destination, so that you can literally find the destination lost sight of. Therefore you have to switch back to the original map scale after operating the zoom device so that you can find the destination again. The temporary zooming of the road map distracts the driver undesirably from the observation of the traffic situation, so that this option should only be used when the vehicle is at a standstill. The invention is based on the problem of developing a method for vehicle navigation which enables the road map to be displayed on the largest possible scale during the entire journey without the need for manual switching of the map scale.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass bei Fahrtbeginn durch Bestimmung der Fahrzeugposition und Eingabe des Fahrziels zunächst eine Straßenkarte eines solchen Kartenmaßstabes angezeigt wird, dass sie die Fahrzeugposition und das Fahrziel zeigt, und dass nach Fahrtbeginn mit zunehmender Annäherung an das Fahrziel der Kartenmaßstab der Kartendarstellung automatisch derart vergrößert wird, dass unter Ausnutzung der vollen Größe des Displays stets das Fahrziel und die jeweilige Fahrzeugposition auf der Straßenkarte erkennbar sind.This problem is solved according to the invention in that at the start of the journey, by determining the vehicle position and entering the destination, a road map of such a map scale is first displayed that it shows the vehicle position and the destination, and that after the start of the journey, the map scale of the map display increases as the destination approaches is automatically enlarged in such a way that, using the full size of the display, the destination and the respective vehicle position are always recognizable on the road map.
Durch diese Art der Darstellung kann die auf dem Display gezeigte Straßenkarte stets einen solchen Kartenmaßstab haben, dass sich die Fahrzeugposition und das Fahrziel nahe von entgegengesetzten Rändern des Displays befinden. Es wird deshalb automatisch immer nur derjenige Bereich angezeigt, der mit der Annäherung an das Fahrziel für den Fahrer noch interessant ist und dabei stets die volle Größe des Displays ausgenutzt.With this type of display, the road map shown on the display can always have a map scale such that the vehicle position and the destination are close to opposite edges of the display. For this reason, only that area is automatically shown that is still interesting for the driver when approaching the destination and always uses the full size of the display.
Optimal viele Details lassen sich auf der Straßenkarte darstellen, wenn der Kartenmaßstab kontinuierlich mit der Annäherung an das Fahrziel vergrößert wird.An optimal number of details can be shown on the road map if the map scale is continuously enlarged as you approach the destination.
Die Programmierung der Fahrzeug-Navigationseinrichtung ist weniger aufwendig, wenn man sich damit begnügt, dass der Kartenmaßstab in mehreren Stufen mit der Annäherung an das Fahrziel vergrößert wird. Besonders leicht kann sich ein Kraftfahrer orientieren, wenn gemäß einer anderen Weiterbildung der Erfindung auf der Straßenkarte die jeweilige Fahrzeugposition kontinuierlich nahe eines Randes des Displays angezeigt wird.The programming of the vehicle navigation device is less complex if one is content with the fact that the map scale is enlarged in several stages with the approach to the destination. A motorist can orient himself particularly easily if, according to another development of the invention, the respective vehicle position is continuously shown on the road map near an edge of the display.
Zur weiteren Verdeutlichung der Erfindung wird nachfolgend auf die Zeichnung Bezug genommen. Diese zeigt in den Figuren 1 bis 4 ein Display mit einer darin dargestellten Straßenkarte. Die Figur 1 zeigt die Darstellung bei Fahrtbeginn. Nahe der rechten unteren Ecke ist die anfängliche Fahrzeugposition mit "Start Babenhausen" und nahe des linken Randes in der Mitte das Fahrziel mit "Arrival Flughafen" gekennzeichnet. Die Figuren 2 bis 4 zeigen die sich automatisch mit der Annäherung an das Fahrziel ergebende Darstellung mit größer werdendem Maßstab. Die Darstellung gemäß Figur 4 lässt für den Fahrer die genaue Lage der Flughafengebäude und insbesondere des Parkhauses erkennen. To further clarify the invention, reference is made below to the drawing. This shows in Figures 1 to 4 a display with a road map shown therein. Figure 1 shows the representation at the start of the journey. Near the bottom right corner, the initial vehicle position is marked "Start Babenhausen" and near the left edge in the middle the destination is labeled "Arrival Airport". Figures 2 to 4 show the automatically resulting with the approach to the destination with increasing scale. The representation according to FIG. 4 shows the exact position of the airport building and in particular the parking garage for the driver.
