A method for operating a navigation system of a vehicle includes providing one or more dedicated route options, transmitting a first signal for requesting one or more route options to a vehicle-external data processing device, and receiving a second signal from the vehicle-external data processing device, where the second signal identifies one or more route options provided by the vehicle-external data processing device for route calculation. The method also includes outputting at least one of the dedicated route options and at least one of the route options identified in the second signal, and detecting at least one input of a user of the navigation system corresponding to a selected one of the outputted route options. If the selected route option is one of the route options identified in the second signal, the method includes transmitting a third signal that identifies the selected route option to the vehicle-external data processing device, and receiving a fourth signal from the vehicle-external data processing device identifying a route assigned to the selected route option and calculated by the vehicle-external data processing device. If the selected route option is one of the dedicated route options, the method also includes calculating a route assigned to the selected route option, and outputting the calculated route.

Method for operating a navigation system

A system and method for navigating a vehicle includes a management unit (server) arranged outside of the vehicle for centrally storing traffic information and traffic rules relating to vehicle information. The traffic rules relate, for example, to road closures and restrictions based on vehicle type. A detection unit has an interface for detecting vehicle information of the vehicle, such as at least one vehicle identification number, and is designed to transmit the detected vehicle information of the vehicle to the managing unit. A computing module generates navigation information based on traffic rules stored on the managing unit and vehicle information. The generated navigation information is output in the vehicle by a navigation unit (client).

The route from a prescribed starting node to a prescribed destination node is determined on the basis of digital map data stored in a memory unit such that, for possible expansion of a respective current node, total costs are determined for the current node on the basis of a sum of edge costs for an optimum route from the starting node to the current node and a destination-node-related heuristic value for the current node and a prescribed destination-node-related correction value. The destination-node-related correction value is in this case representative of a mean value for cost ratios for respective nodes in a prescribed set, wherein the respective cost ratios are dependent on the edge costs of the connections that are situated between the current node and the respective node in the set and that represent an optimum route between the current node and this node in the set and on a heuristic value for the current node in relation to this node in the set.

Method and apparatus for determining a route and correction values for heuristic values

A predefined area is divided into a plurality of tiles, a respective one of the tiles of the area being determined as a starting tile and the respective remaining tiles being determined as reference tiles, and special nodes, being predefined that are arranged in the starting tile or in the respective reference tile. For the respective starting tile, a correction value is determined, in each case in relation to one of the reference tiles, such that a respective cost ratio is determined for each special node of the respective starting tile in relation to each special node of the reference tile on the basis of the edge costs of the connections that are situated between the respective special node of the starting tile and the respective special node of the reference tile. The cost ratio is also determined on the basis of a heuristic value of the respective special node of the starting tile in relation to the respective special node of the reference tile. A mean value is determined on the basis of the determined cost ratios. The mean value is taken as a basis for determining the correction value of the starting tile in relation to the respective reference tile.

Method for determining correction values for a route calculation algorithm

A first user device comprises a first communication interface and a second communication interface. The first user device has digital first map information and is configured for outputting a request message for making navigation information available with regard to at least one desired route section, at the first communication interface. The second communication interface is configured for receiving navigation information that is made available in response to the request message, at the second communication interface, and comprises digital second map information for at least a part of the at least one desired route section. The digital second map information comprises data for display of the at least one part of the at least one desired route section. The first user device is configured for determining digitally updated map information as a function of the digital second map information of the navigation information and of the digital first map information, and for selecting an optical output device for display of the digital updated map information.

User device and system

A navigation system has an interface for accessing a memory unit, in which an electronic road map is stored with a large number of road sections, each of which has at least one first cost element assigned thereto, and has a computer unit, which is designed such that at least one second cost element is assigned or will be assigned to at least some of the road sections. In order to compute a route, a cost value is assigned or will be assigned to each of the road sections, wherein the computation of the cost value for the first road sections is based in each case on the first and the second cost element and for the second road sections is based in each case on the first and not on the second cost elements.

Navigation system and method for computing the overall costs of a route

A motor vehicle navigation system and method uses an output device for the acoustic output of driving maneuver information and a processor device which is equipped such that a route to be traveled is determined. Driving maneuver information is determined based on the route to be traveled and on an actual position. An alternate route is computed, assuming that the determined driving maneuver information is not observed. As a function of the difference between the route and the alternate route, particularly with respect to the expected driving time, driving distance and/or driving cost, the driving maneuver information is either acoustically emitted or not.

Motor vehicle navigation system

A method for the operation of a navigation device, and a corresponding navigation device are provided. Multiple route elements are received which each have at least one parameter. The route elements characterize a route. Each of the route elements are assigned to local route elements which are stored in a digital memory card stored in the navigation device. A quality coefficient for the assignability to a local route element is determined for each of the route elements depending on at least one of the at least one parameters. A route reconstruction quality coefficient is determined depending on the respective quality coefficients of the route elements.

Method for the operation of a navigation device, and navigation device

In the case of a system for marking a region within an image of a road map detail displayed on a vehicle video screen, a regional location can first be selected by a control element. The region, which represents one of several administrative levels, can be constantly fixed via an enter function of the control element. The administrative level and thereby the size of the region can be changed by a rotational movement of the control element, which can be rotated about a longitudinal axis.

A navigation system has a display device for displaying a predefined maximal number of graphic driving lane objects. A control device is operatively configured such that the actual number of driving lanes of a street or road is determined, and only a maximal number of graphic driving lane objects is displayed on the display device when the maximal number is smaller than the actual number of driving lanes.

Navigation system and method

In the case of a method for the input of input data into a vehicle navigation device, by which input data are supplied to the vehicle navigation device by way of a receive interface and the input data are subjected to a plausibility check, in the event of a negative plausibility check, a prompt is emitted for correcting the input data. The input data can be corrected by a user via an operating device, and the corrected input data are imported into the vehicle navigation device.
