摘要:
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.
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 method for operating a navigation system and a navigation system for a vehicle, a motor vehicle in particular, data concerning geographic positions of the vehicle being determined by a position-finding system and transmitted to an electronic data processing device having access to a database and a digital road map. Based on this data, the location of the vehicle on the digital road map is determined and route guidance instructions are output to the driver of the vehicle acoustically and/or visually. Also, information from the navigation system may be used for traveling routes selected by the driver himself before the start of the trip and to which the navigation system does not output any route guidance instructions. Routes selected by the driver himself are entered into the navigation system and stored by a route memory of the navigation system.
摘要:
A method for navigating from a starting location to a destination location includes calculating a total route that is divided into at least two partial routes, at least one partial route being calculated locally in a mobile navigation client and at least one other partial route being calculated centrally in a stationary route server. At least one transfer point is ascertained as the end point of a first partial route and as the starting point of a second partial route as a function of the resulting total route.
摘要:
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:
A method for operating a navigation system and a navigation system for a vehicle, in which data regarding geographic positions of the vehicle are ascertained by a positioning system and transmitted to an electronic data processing device having access to a database and a digital road map, on the basis of this data the location of the vehicle on the digital road map is determined and destination guidance instructions are output visually and/or acoustically to the driver of the vehicle, wherein additional information can be stored in the navigation system and can be retrieved as necessary by the driver and/or other passengers in the vehicle and output via the navigation system, this additional information being loaded into the navigation system in the form of program “navlets” which are usable by the driver and/or other passengers in the vehicle.
摘要:
A method and a device are described for managing traffic-relevant events in a vehicle-based navigation system. A traffic information database, 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 as traffic information and used for updated route planning.
摘要:
In an electronic device, in particular a navigation device, having operator-input devices and communications devices for exchanging data with an external, central computer, at least one operator-input device is assigned a function for sending a specific input-identification code uniquely assigned to the electronic device and to the respective operator-input device, or for sending function data assigned to the input-identification code, to the external, central computer for executing the at least one function defined by the input-identification code and the function data.
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.
