Abstract
A server method of receiving a precise digital map for navigation or autonomous driving as a plurality of partial precise digital maps corresponding to servers respectively proximate to portions of a navigation path.
Claims20
A server for providing a vehicle a precise digital map of a traveling path of the vehicle, the server comprising:
- a processor configured to divide the traveling path into a plurality of sections of the traveling path, determine a plurality of edge servers respectively corresponding to each section among the plurality of sections of the traveling path, each edge server among the plurality of edge servers respectively providing a partial precise digital map that is a portion of the precise digital map corresponding to a section among the plurality of sections to the vehicle, and determine a time point at which the partial precise digital map of each section among the plurality of sections of the traveling path is transmitted to the vehicle by using an expected traveling time from a current position of the vehicle to a starting position of each section;
- and
- a transceiver configured to receive, from the vehicle, a request for the precise digital map of the traveling path of the vehicle and to transmit, based on the determined time point, a request to the plurality of edge servers respectively corresponding to the plurality of sections of the traveling path to respectively transfer the partial precise digital map corresponding to the section of the traveling path when the vehicle respectively approaches each section of the traveling path among the plurality of sections of the traveling path.
A method of providing a vehicle a precise digital map of a traveling path of the vehicle, the method comprising:
- receiving, from the vehicle, a request for the precise digital map of the traveling path of the vehicle;
- dividing the traveling path into a plurality of sections of the traveling path;
- determining a plurality of edge servers respectively corresponding to each section among the plurality of sections of the traveling path, each edge server among the plurality of edge servers respectively providing a partial precise digital map that is a portion of the precise digital map corresponding to a section among the plurality of sections to the vehicle;
- determining a time point at which the partial precise digital map of each section among the plurality of sections of the traveling path is transmitted to the vehicle by using an expected traveling time from a current position of the vehicle to a starting position of each section;
- and
- requesting the plurality of edge servers respectively corresponding to the plurality of sections of the traveling path to respectively transfer the partial precise digital map corresponding to the section of the traveling path based on the determined time point when the vehicle respectively approaches each section of the traveling path among the plurality of sections of the traveling path.
