Personal mobility device, server for communicating with the same, and method of controlling the server

A server comprising:

• a communication module;
• and
• a controller configured to:
• recognize a personal mobility device that has transmitted storage location information including communication information and initial location information among storage location information of a plurality of personal mobility devices received through the communication module as a first personal mobility device;
• recognize a personal mobility device that has transmitted storage location information including the initial location information but not including the communication information as a second personal mobility device;
• obtain location error information based on the communication information and the initial location information of the first personal mobility device;
• correct the initial location information of the second personal mobility device based on the location error information;
• and
• transmit the corrected initial location information to the second personal mobility device;
• wherein the controller is configured to correct the initial location information of the first personal mobility device based on the location error information and to transmit the corrected initial location information to the first personal mobility device, set a radius based on the location error information and weather information, set a clustering area based on the set radius and the corrected initial location information of the first personal mobility device, and correct the initial location information of the second personal mobility device in the set clustering area based on the location error information.

A method of controlling a server, the method comprising:

• recognizing a personal mobility device which has transmitted storage location information including communication information and initial location information among storage location information of a plurality of personal mobility devices received through a communication module as a first personal mobility device;
• recognizing a personal mobility device which has transmitted storage location information including the initial location information and not including the communication information as a second personal mobility device;
• obtaining location error information based on the communication information and the initial location information of the first personal mobility device;
• correcting the initial location information of the second personal mobility device based on the location error information;
• and
• transmitting the corrected initial location information to the second personal mobility device;
• wherein correcting the initial location information of the second personal mobility device comprises:
• obtaining information about a distance between two first personal mobility devices of the plurality of personal mobility devices with corrected initial location information based on the initial location information of the two first personal mobility devices;
• establishing a clustering area based on the distance information;
• identifying the second personal mobility device present in the established clustering area;
• and
• correcting the initial location information of the second personal mobility device based on the location error information of the two first personal mobility devices.
