Abstract

A method of exchanging navigation information between a terminal, an offboard vehicle navigation device in particular, and a control center is described, the navigation information including route information for at least one route between a starting point and a destination. The method involves the following steps: a) verifying a starting point reference ID and/or starting coordinates and verifying a destination reference ID and/or destination coordinates and b) calculating route data and transmitting to the terminal a route response containing at least parts of the route data, the route data corresponding to at least one complete route from the starting point to the destination or at least one partial route from the starting point to an intermediate point located between the starting point and the destination at least as a function of the length of the route from the starting point to the destination.

Dependent claims

A method of exchanging navigation information between a terminal and a control center, the navigation information including route information for at least one route between a starting point and a destination, the method comprising:

verifying at least one of a starting point reference ID and starting coordinates;
verifying at least one of a destination reference ID and destination coordinates;
calculating route data;
transmitting to the terminal a route response containing at least a part of the route data, wherein the route data correspond to one of the at least one route and at least one partial route from a starting point to an intermediate point located between the starting point and the destination at least as a function of a length of the at least one route, and wherein the intermediate point has at least one of a verified intermediate point reference ID and verified intermediate point coordinates;
and
requesting additional route data from the control center via one of the terminal and a separate device before the intermediate point is reached, wherein:
the terminal includes a mobile terminal, and
the additional route data corresponding to one of a route from the intermediate point to the destination and a route from the intermediate point to an additional intermediate point.
