Abstract: A system for autonomously driving a vehicle along a road segment using map data including coordinate information of a landmark disposed along a road, includes at least one processor. The map data is distributable from a predetermined server to the vehicle in patch units, which are data sets for different areas. The processor is configured to: acquire a position of the vehicle based on a detection result of a positioning sensor mounted on the vehicle; and set a patch as a download target including a road which has a possibility that the vehicle passes through and is determined based on a current position of the vehicle.

Abstract: A method for uploading a probe data, including coordinate information of a plurality of features disposed along a road, to a server, includes: acquiring at least one peripheral object data, representing a feature disposed around a vehicle, from a peripheral monitoring sensor mounted on the vehicle; analyzing the peripheral object data and calculate a position of the feature with respect to the road on which the vehicle travels; and generating the probe data including position information of the feature and uploading the probe data to the server. The uploading includes a first mode in which the probe data is uploaded to the server at a predetermined frequency, and a second mode in which the probe data is uploaded at a lower frequency than the first mode.
