Abstract

In a navigation system, particularly for vehicles, with means for position determination, a navigation terminal comprises an operating facility, a display facility, an announcement memory and a transmitter/receiver and is connected, at least intermittently, to a central computer. A navigation system with such a navigation terminal is particularly cost-effective since there is no need for data on the traffic network (road maps) to be stored in the navigation terminal.

Claims

1. Method for navigating by means of a user-side navigation terminal, particularly of vehicles, in which such a navigation terminal is located, with the following method steps:

a. selection of a travel destination from a list via the navigation terminal;

b. transmission of the selected travel destination and of the current location to a remotely located central computer;

c. calculation of one or more travel route(s) and/or the corresponding travel time;

d. transmission of the travel route and/or the travel time from the central computer to the navigation terminal.

2. Method according to claim 1, wherein the travel route is calculated with regard to conditions entered in the navigation terminal by the user.

3. Method according to claim 1, wherein the position of the navigation terminal is determined and/or the calculated route is divided into route sections and the average travel speed is determined for each route section.

4. Method according to claim 1, wherein announcements are made to the user by the navigation terminal and, when a defined announcement or route position is reached, a connection is established between the navigation terminal and the central computer and announcement texts and position markers are transmitted to the navigation terminal by the central computer.

5. Method according to claim 4, wherein, simultaneously during the connection of the navigation terminal to the central computer, the average travel speed for a route section is transmitted to the central computer and/or the communication between the navigation terminal and the central computer is effected in packets and/or the information transmitted by the navigation terminal is used to calculate travel routes for other users and/or generate statistics.

6. Navigation system, particularly for vehicles, with means for position determination, a navigation terminal comprising an operating facility, a display facility, an announcement memory and a transmitter/receiver and being connected, at least intermittently, to a central computer via data transmission means.

7. Navigation system according to claim 6, wherein a modified mobile telephone is provided as a navigation terminal and a hands-free device is preferably provided for the mobile telephone.

8. Navigation system according to claim 6, wherein a memory unit for storing a software for speech synthesis is provided for the navigation terminal.

9. Navigation system according to claim 6, wherein a mobile telephony network and/or a gateway to the internet and/or the internet is/are provided as a means for data transmission.

10. Navigation system according to claim 6, wherein a server is provided as a central computer, in which a list containing location information is stored.
