Abstract: A method of route planning in a navigation system, takes place in three steps. In a first step, a quantity of first travel routes is determined on the basis of an optimization criterion, and location-independent and situation-specific user preferences derived therefrom. In the second step, the first travel routes are recalculated in sub-segments on the basis of location-dependent and situation-specific user preferences. In the third step, the determined travel routes are prioritized on the basis of at least one rating criterion. The intermediate results obtained may be displayed for the user after each step, so that the user may select one of the routes if necessary and thus end the method early. The operating behavior of the user and/or the way in which the user follows the route recommendations may be monitored and statistically evaluated, making it possible to customize the rating criteria and user preferences for route planning.

Abstract: In order to create a method for operating a navigation system and a navigation system for a vehicle, in particular for a motor vehicle, in which data regarding geographical positions of the vehicle are ascertained by a positioning system (20) and transmitted to a device for electronic data processing having access to a database (14) and a digital road map, and on the basis of those data the location of the vehicle on the digital road map is determined, and destination guidance instructions are outputted visually and/or acoustically to the driver of the vehicle, with which additional information can easily be stored in the navigation system and can be retrieved as necessary by the driver and/or by other persons in the vehicle and outputted via the navigation system, provision is made for additional information relevant for navigation to be loaded into the navigation system in the form of user programs which, as so-called “navlets” (30), are usable by the driver and/or by other persons present in th

Abstract: Proposed is a method and a navigation device, a method for selecting map information from a digital map on the basis of a predefined polyline being used on the digital map, and, in addition to the information defined by the polyline, the map information including further information regarding a route corridor.

Abstract: Proposed is a navigational system (1), which provides a user with a plurality of routes between a starting point (S) and a destination (Z) for selection. The navigational system (1) includes a calculation unit (400) for calculating a first route (5) from starting point (S) to destination (Z). It further includes a reproducing device (700) for reproducing the calculated first route (5). The calculation unit (400) calculates at least one second route (10), which differs from first route (5), from starting point (S) to destination (Z). The reproducing device (700) reproduces the at least one calculated second route (10) in addition to the first route (5).

Abstract: For the purpose of making available route data for a navigational device, an overall route is divided up into route segments which each include a part of the overall route. A first route segment is transmitted to the navigational device, upon its request, which around the starting point includes a starting field including a plurality of possible routes, as well as a main route to an intermediate destination. Before the intermediate destination is reached, a further route segment is transmitted to the navigational device, which includes a plurality of possible routes around the intermediate destination as its starting field, as well as a main route to an additional intermediate destination or to the destination itself. The latter step is repeated for route segments for further intermediate destinations until the destination is reached.

Abstract: The method is used for the user-defined setting of a driver information system (10), in which data are stored and are retrievable for making a decision. In this context, it is provided that a user-defined decision matrix (26) is set up which is adjustable as a function of operating data and is retrievable for making a preliminary decision with the aid of the information system (10).

Abstract: A device and a method of detecting and preprocessing vehicle data, traffic data, and/or driver data, such as the speed, direction of travel, engine condition, weather conditions, heart rate, etc., is described, in which the time and location of recording the data are also recorded in addition to the data mentioned. The position determination may be accomplished in particular by a positioning system such as GPS. The position may be adjusted using a digital map. The recorded data is preferably preprocessed in real time (4), coded, and/or compressed and/or subjected to a statistical analysis (5), linked mathematically/logically (6) and recorded and/or transmitted (7).

Abstract: A method and a device are described for managing traffic-relevant events in a vehicle-based navigation system. A traffic information database (1810), which can be updated by the driver in particular through prioritized driver queries initiated by the system concerning the traffic situation is managed in the navigation system. Thus observations made by the driver during his trip can be stored in the database (1810) as traffic information and used for updated route planning.

Abstract: A method for determining the position of a land vehicle having a navigational system, and a device for implementing the method. A combined evaluation of the data that are receivable from a satellite navigation system and from a terrestrial, cellular mobile telephony network is undertaken. Moreover, the accuracy of the position calculable from the receivable data is estimated, and the position is then calculated on the basis of the data having the highest estimated accuracy.
