COMMUNICATION METHOD AND SERVER
First Claim
1. A method used in a server, comprising:
- receiving, from a roadside unit placed on a road, first data that is acquired by a first sensor mounted in the roadside unit and that is indicative of information on surroundings of the roadside unit;
configurating a dynamic map by superimposing time-changing information on the road onto a static map including the road on a basis of the received first data;
computing a first region that is incapable of being observed by the first sensor, the first region being included in a region indicated by the dynamic map;
receiving a plurality of attribute information items from a respective plurality of vehicles running on the road, the plurality of attribute information items being related to a respective plurality of second sensors mounted in the respective plurality of vehicles;
selecting a specific second sensor from among the plurality of second sensors on a basis of the plurality of attribute information items and the first region;
receiving specific second data acquired by the specific second sensor among a plurality of pieces of second data acquired by the plurality of second sensors, the plurality of pieces of second data being indicative of information on surroundings of the respective plurality of vehicles;
reconfigurating the dynamic map by filling the first region by using the received specific second data; and
distributing the reconfigurated dynamic map to at least one of the plurality of vehicles.

Abstract
A method used in a server includes configurating a dynamic map by superimposing time-changing information on a road onto a static map based on first data indicative of surrounding information acquired by a first sensor mounted in a roadside unit; computing a first region that is incapable of being observed by the first sensor; receiving a plurality of attribute information items related to respective second sensors mounted in respective vehicles running on the road from the vehicles; selecting a specific second sensor from among the second sensors based on the attribute information items and the first region; receiving specific second data acquired by the specific second sensor among a plurality of pieces of second data acquired by the second sensors; reconfigurating the dynamic map by filling the first region by using the specific second data; and distributing the reconfigurated dynamic map to at least one of the vehicles.
