摘要:
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, coded, and/or compressed and/or subjected to a statistical analysis, linked mathematically/logically and recorded and/or transmitted.

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).
摘要:
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.

A method and a device for transmitting navigation information from a data processing center to an on-board navigation system. The device includes a request profile generating device for generating an individual request profile according to the navigation information required by the on-board navigation system, a communication device for transmitting the individual request profile from the navigation system to the data processing center via a wireless interface, a preparation device provided in the data processing center for analyzing the transmitted individual request profile and preparing the navigation information required in the on-board navigation system and transmitting back the required navigation information from the data processing center to the on-board navigation system via the wireless interface, and a navigation information integrating device for integrating the back-transmitted, required navigation information into the on-board navigation system.
摘要:
In methods for encoding and decoding objects with reference to a traffic route network, wherein the encoded information can also be decoded with the aid of databases that differ from a database used in the encoding, the objects are provided with relationships to at least one relational object which is present in databases that are used for the decoding, and the relationships do not primarily result from the traffic route network. A position indication can also be provided with a position type designator, which for instance indicates whether the transmitted position is an exact or navigable position or is the location of a search space.

摘要:
In a navigational system for generating route recommendations and for target tracking, a system (500, 800) is proposed, which detects vehicle-, traffic-, and/or driver-related data and which from these data can derive patterns of behavior of the user. The patterns of behavior as well as the user preferences derived therefrom can then be used to apply individually adapted optimization criteria to the specific user in calculating the route.When patterns of behavior are detected that deviate from the usual behavior, the detection of sensor information can automatically be expanded in order, in a plausibility check, to establish causes for the deviations and to derive therefrom new user preferences, if appropriate.
摘要:
A navigation system for a motor vehicle includes at least one storage device, at least one navigation map being stored on each storage device, which is read out using a reading device. Associated with the reading device is a changeover device for exchanging storage devices that are to be read out by the reading device. A navigation map and information regarding the instantaneous position of the motor vehicle are displayed to a vehicle occupant via a display device. A control device for the changeover device controls the changeover device so that a point in time for changing over the storage device is identifiable so that during the changeover operation of the storage device, a deviation of the motor vehicle from the route segment currently being traveled is improbable based on the current navigation data of the motor vehicle.
