Combined offboard and onboard navigation system and method
First Claim
1. Navigation system comprising:
- a server system connected to internet, having a first cartographic database and a first routing engine, adapted to calculate routes from starting points to destination points, taking into account traffic information,a mobile device wirelessly connected to the server system, having geolocating means to determine a current location, having a second cartographic database and a second routing engine, wherein the second cartographic database may exhibit differences with regard to the first cartographic database,wherein said mobile device is adapted to determine a destination point, and to transmit a corresponding routing request to the remote server system,wherein the server system is adapted to;
calculate a primary route from the current location to said destination point, said primary route comprising a list of maneuvering points each maneuvering point comprising geo-coordinates and a maneuver to be performed,wherein the server system is adapted to;
calculate a list of waypoints, said waypoints being located on the primary route and spaced away from the maneuvering points, the list of waypoints generally not including the maneuvering points,send this list of waypoints to the mobile device, and wherein the second routing engine is adapted to establish a secondary route, from said current location to said destination point, based on the waypoints and on the second cartographic database, without requiring the reception from the server system of maneuvering points or maneuver instructions or cartographic data, whereby only a limited bandwidth wireless connection is required between the mobile device and the server system.

Abstract
Navigation system and method comprising a server system with a navigation server (6) and a host server (7) connected to internet, having a first cartographic database (61) and a first routing engine, a mobile device (8) having geolocating means to determine a current location, having a second cartographic database (81) and a second routing engine, wherein the mobile device transmits a routing request to the remote server system, wherein the server system calculates a primary route (4) from the current location (3) to the destination point (2), said primary route comprising a list of maneuvering points each maneuvering point, wherein the server system calculates a list of waypoints located on the primary route, spaced away from the maneuvering points, the second routing engine establishing therefrom a secondary route (5), based on the waypoints and on the second cartographic database.

9. Navigation method carried out by a navigation system comprising:
-
a system server connected to internet, having a first cartographic database and a first routing engine, adapted to calculate routes from starting points to destination points, taking into account traffic information, a mobile device wirelessly connected to the server system, having geolocating means to determine a current location, having a second cartographic database and a second routing engine, which does not require the reception from the server system of maneuvering points or cartographic data, wherein the second cartographic database may exhibit differences with regard to the first cartographic database, said navigation method comprising the following steps; a—
) a geolocating step wherein said mobile device determines its current location,b—
) a destination determination step wherein said mobile device determines a destination point,c—
) a routing requesting step wherein the mobile device transmits a routing request to the remote server system,d—
) a calculating step wherein the server system calculates a primary route leading from said current location to said destination point, said primary route comprising a list of maneuvering points, each maneuvering point comprising geo-coordinates and a maneuver instruction to be performed,f—
) a waypoint calculating step wherein said server system calculates a list of waypoints, said waypoints being located on the primary route and spaced away from the maneuvering points, the list of waypoints generally not including the maneuvering points,g—
) a waypoint sending step wherein the server system sends said list of waypoints to the mobile device,h—
) a secondary route establishing step wherein the second routing engine establishes a secondary route based on said waypoints and on the second cartographic database, whereby only a limited bandwidth wireless connection is required between the mobile device and the server system. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
