Abstract
Disclosed herein is a technique for processing map change data in a map client that uses the map changes to apply changes and updates to current map data. The map client provides the updated map data to other components in an autonomous vehicle. The map change data describes the processing in the map client to obtain updated map data from the map data.

1-13. (canceled)
A computer-implemented method at a client computer system in an autonomous vehicle, the client computer system comprising an automated driving system, the client computer system arranged to receive and store high definition (HD) map data representing a road system having a plurality of objects, the HD map data comprising a plurality of map features representing the plurality of objects of the road system, the HD map data for use by the automated driving system, the method comprising:
- receiving map change data describing a change in one or more map features of the plurality of map features of the HD map data, wherein the map change data is received independently from receipt of the HD map data;
- processing the map change data to identify updated map features that are ones of the one or more map features associated with a specified portion of the road system;
- and
- based on the map change data relating to the updated map features, generating an updated HD map data for the specified portion of the road system so as to enable use of the updated HD map data by the automated driving system.
A client computer system in an autonomous vehicle, the client computer system comprising:
- a memory having stored therein high definition (HD) map data representing a road system having a plurality of objects, the HD map data comprising a plurality of map features representing the plurality of objects of the road system, the HD map data for use by the automated driving system;
- an automated driving system;
- and
- one or more processors, the one or more processors configured to:
- receive map change data describing a change in one or more map features of the plurality of map features of the HD map data, wherein the map change data is received independently from receipt of the HD map data;
- process the map change data to identify updated map features that are ones of the one or more map features associated with a specified portion of the road system;
- and
- based on the map change data relating to the updated map features, generate an updated HD map data for the specified portion of the road system so as to enable use of the updated HD map data by the automated driving system.
A non-transitory computer readable storage medium storing instructions that, when executed by one or more processors in a client computer system in an autonomous vehicle, the client computer system comprising an automated driving system and the client computer system storing high definition (HD) map data representing a road system having a plurality of objects, the HD map data comprising a plurality of map features representing the plurality of objects of the road system, the HD map data for use by the automated driving system, causes the one or more processors to perform a method comprising:
- receiving map change data describing a change in one or more map features of the plurality of map features of the HD map data, wherein the map change data is received independently from receipt of the HD map data;
- processing the map change data to identify updated map features that are ones of the one or more map features associated with a specified portion of the road system;
- and
- based on the map change data relating to the updated map features, generating an updated HD map data for the specified portion of the road system so as to enable use of the updated HD map data by the automated driving system.
