Devices and methods for updating maps in autonomous driving systems in bandwidth constrained networks

A communication device for a vehicle to communicate features about the vehicle's environment to one or more neighboring vehicles, the communication device including one or more processors configured to:

• divide stored data about the vehicle's environment into a plurality of subsets of data, wherein a respective amount of data in each of the plurality of subsets is less than the stored data;
• determine a confidence metric for each of the plurality of subsets of data;
• and
• select one or more subsets from the plurality of subsets of data and their corresponding confidence metrics for transmission, wherein the confidence metric is associated with a global reference coordinate system for an area covered by the one or more neighboring vehicles and a number of allowed transmissions to be sent from the vehicle.

A non-transitory computer readable medium, comprising instructions which, if executed, cause one or more processors to:

• receive a communication from another device, where the communication includes a global reference coordinate system for an area covered by the other device and a number of allowed transmissions to be sent from the vehicle;
• transform stored data about the vehicle's environment based on the global reference coordinate system;
• divide the transformed stored data into a plurality of subsets of data;
• and
• select one or more subsets of data from the plurality of subsets for transmission according to the allowed transmission.
