Method and Apparatus for Transferring Positions Between Different Map Data

A method for referencing a route, based on first map data, of a vehicle to second map data, the method comprising:

• determining first positions on the route with respect to the first map data;
• allocating a lane on which the vehicle is driving at each of the first positions;
• providing the first positions with corresponding allocated lanes;
• and
• determining second positions with respect to the first positions and the corresponding allocated lanes.

An apparatus for referencing a route, based on first map data, of a vehicle to second map data, the apparatus comprising:

• a first map store for the first map data;
• a second map store for the second map data;
• and
• a processing device, which is configured to:
• determine first positions on the route with respect to the first map data;
• allocate a lane on which the vehicle is driving at each of the first positions;
• provide the first positions with corresponding allocated lanes;
• and
• determine second positions with respect to the first positions and the corresponding allocated lanes.

A method comprising:

• providing first map data used by a first vehicle system relating to a route of the vehicle;
• determining first positions on the route with respect to the first map data;
• allocating a lane on which the vehicle is driving at each of the first positions;
• providing the first positions with corresponding allocated lanes;
• determining second positions in the second map data with respect to the first positions and the corresponding allocated lanes;
• and
• using the second map data in a second vehicle system.
