Information processing device and method for processing map data used for autonomous driving of vehicle

An information processing method for processing map data used for autonomous driving of a vehicle, the map data including node information regarding a plurality of nodes corresponding to points on a road and link information regarding links connecting the nodes, each link connecting a pair of adjacent nodes among the plurality of nodes, the information processing method comprising:

• updating the map data stored in a map database from old map data to new map data;
• performing an update determination as to whether autonomous driving availability information associated with the link information is updatable, based on a degree of match between the link information in the old map data and the link information in the new map data;
• and
• carrying over, from the old map data to the new map data, the autonomous driving availability information associated with the link information determined to be updatable as a result of the update determination.

A computer program product comprising instructions which, when executed by a computer, cause the computer to carry out a method for processing map data used for autonomous driving of a vehicle, the map data including node information regarding a plurality of nodes corresponding to points on a road and link information regarding links connecting the nodes, each link connecting a pair of adjacent nodes among the plurality of nodes, the method comprising:

• updating the map data stored in a map database from old map data to new map data;
• performing an update determination as to whether autonomous driving availability information associated with the link information is updatable, based on a degree of match between the link information in the old map data and the link information in the new map data;
• and
• carrying over, from the old map data to the new map data, the autonomous driving availability information associated with the link information determined to be updatable as a result of the update determination.
