Abstract: A system and method for determining and displaying a navigation route on a navigation device from one vehicle position to a travel destination. The navigation device can include processor with RAM, a mass storage device for holding a database with geographic data, as well as a display. Embodiments of the invention can provide a high level of correlation between the actual situation on the road as seen by the user and the corresponding navigation maneuver displayed on the screen. The graphic output of navigation devices for complex intersections can also be improved regardless of whether the navigation device is a high-performance or very simple device.

Abstract: A device and a method for generating a text object, in particular, for a geographic map illustration. The text object comprises a multitude of letters and serves for identifying, for example, a geographic characteristic on the map illustration. The text object comprises several letters, the font sizes or spacings of which are reduced relative to the spacings between the other letters of the text object. The text object can be displayed on monitors with small dimensions, particularly in the field of navigation systems. It is also possible to display larger text objects such as, for example, long street names on small navigation monitors such that they can be easily recognized without occupying valuable monitor space required for other purposes.

Abstract: A method for operating a navigation device including a processor, a signal receiver for receiving position signals, a road network database that also contains position data on tunnels (tunnel attributes), a position finding unit that determines the current position of the vehicle, a display unit and a display control for controlling the adjustments of the display unit, particularly for regulating the brightness and/or a color scheme of the display unit. The display control is able to change the adjustment of the display unit while driving through a tunnel (tunnel mode). The method can include determining the vehicle position with consideration of the received position signals and automatically activating the tunnel mode of the display unit by means of the display control immediately or with a certain time delay if the determined vehicle position features a tunnel attribute and the received position signals fall short of a predetermined signal quality.

Abstract: The present invention relates to a device and a method for navigating a vehicle along a route from a starting position or an instantaneous position to a destination. To this end, a route calculation device of a navigation device calculates a route course which is composed of a sequence of several coherent roads stored on a digital map of a memory device as a first route, and additionally calculates at least one alternative route by allocating a penalty attribute, especially increased average traveling time, road distance or the like, to at least one road of the first route. The method comprises at least the following steps of: S1: entering at least one destination; S2: calculating a first route; S3: allocating a penalty attribute to at least one road of the first route; S4: calculating at least one additional route; S7: representing the routes and selecting a route; S8: navigational guidance along the selected route.

Abstract: The present invention relates to a method, wherein maneuvering instructions are output (09) for the user of a navigation system (10). For the schematic graphical illustration of a maneuvering instruction at an intersection, the position geometry of the road segments and junctions associated with the intersection is analyzed and a schematic maneuvering view (11) is calculated. In order to illustrate the intersection, predefined illustration elements (01-08) are loaded from a database as a function of the result of the analysis, and/or illustration elements (?) that are individually dependent on the position geometry are calculated.

Abstract: The present invention relates to a method for determining the estimated time of travel and time of arrival in the route determination on a digital road map by means of a speed table and by means of measured user speeds. Moreover, the present invention relates to a corresponding computer program product and to a digital storage medium as well as to a corresponding navigation device. The present invention is characterized by the feature that the speed table is classified into temporal classes (k, l, m, n) for at least one, preferably for each road category (B), wherein one temporal class is respectively allocated separate average speeds as a function of the weekday and/or the time of day (A).
