摘要:
A method of providing navigational information to a vehicle operator includes processing destination information spoken by a vehicle operator with an on - board processing system on a vehicle. The processed voice information is transmitted via a wireless link to a remote data center and analyzed with a voice recognition system at the remote data center to recognize components of the destination information spoken by the vehicle operator. The accuracy of the recognition of the components of the destination information is confirmed via interactive voice exchanges between the vehicle operator and the remote data center. A destination is determined from confirmed components of the destination information, route information to the destination is generated at the remove data center, and the route information transmitted to the on - board processing system from the remote data center via the wireless link.

A method for pre-processing road segment data for optimum route computation, a method for determining optimum routes based on the pre-processed road segment data, and corresponding systems are provided. According to the method for road segment data pre-processing, a tiling is provided and a rank information (r) is computed for a road segment (v) based on the tiling, the rank information (r) being a measure of the relevance of the road segment for optimum routes connecting tiles of the tiling. With the rank information (r) being computed based on map geometry, providing the rank information in a subsequent optimum route computation allows the latter to be performed efficiently, e.g., in a navigation system onboard a vehicle.

Data recorded in a navigation apparatus can be partially updated, and, even when a difference is caused between the versions of spot searching data and map displaying data due to the partial updating, route setup is performed with certainty. When a spot to be a destination is designated by a user, a navigation apparatus 100 determines whether the version of a map file MPF recorded on a HD drive 105 matches the version of the spot searching file RF-k corresponding to the spot. If the versions of the two files MPF and RF-k are determined to match, a system control unit 115 sets a route, on the basis of the POI data of the spot contained in the spot searching file RF-k. If the versions are determined not to match, the system control unit 115 extracts the link ID corresponding to the road closest to the spot from the map file MPF, and sets a route, using the link ID.

Disclosed are a telematics terminal and a method for transmitting route guidance information data fitted to a receiving terminal. The method includes the steps of initializing operational conditions of a mobile communication terminal by transmitting device information of the telematics terminal to the mobile communication terminal when a connection between the telematics terminal and the mobile communication terminal is detected, receiving display performance information from the mobile communication terminal, creating route guidance data to be transferred to the mobile communication terminal for telematics services, selecting a route guidance region to be transferred to the mobile communication terminal from route guidance data based on the display performance information of the mobile communication terminal and reconstructing route guidance data for the selected route guidance region, and transmitting the reconstructed route guidance data to the mobile communication terminal. Thus, it is possible for the users to use telematics services without exchanging the mobile communication terminals.
摘要:
A navigation apparatus acquires geographic information from a server apparatus. When the navigation apparatus does not store any geographic information that provides a continuous route from the starting point to a destination point, it transmits data of the starting point and destination point to the server apparatus to acquire therefrom geographic information that provides a continuous route from the starting point to the destination point. This efficient acquisition of geographic information realizes reduction of communication time and communication costs.

The invention is also related to a vehicle with a navigation device and to a navigation method.
摘要:
The invention relates to a navigation method and a navigation system (100) for motor vehicles, for navigating from a present location to a destination. In response to an emergency user request, the nearest emergency destination to the present location is determined from a database, defined as the destination and a route is calculated from the present location to the emergency destination. The navigation system (100) comprises a memory (22) with a database for emergency destinations and a device (26) for determining the nearest emergency destination to the present location from the database.
