US 2024/0175967 A1 · DEVICE AND METHOD FOR V2X COMMUNICATION

Abstract

A method for obtaining, by a vehicle, information regarding its own location through V2X communication is disclosed. Specifically, the method for obtaining location information of a vehicle may comprise the steps of: receiving a V2I message including location information of a road side unit (RSU) from the RSU; receiving a V2X message including reception time information related to a time when the V2I message is received from each of a first surrounding vehicle and a second surrounding vehicle; calculating a relative position of the RSU relative to the current vehicle on the basis of the reception time information and the time at which the current vehicle received the V2I message; and acquiring the location of the current vehicle on the basis of the relative location of the RSU and the location information of the RSU.

Dependent claims

A method performed by a first device, the method comprising:

receiving, from an infrastructure unit, a first signal including absolute position information related to the infrastructure unit;
receiving, from each of a second device and a third device, a second signal including reception time information;
obtaining a relative position of each of the second device and the third device to the first device;
calculating a relative position of the infrastructure unit to the first device, based on i) the reception time information and ii) the relative position of each of the second device and the third device to the first device;
and
obtaining an absolute position of the first device based on i) the relative position of the infrastructure unit to the first device and ii) the absolute position information of the infrastructure unit.
