Abstract

Disclosed herein is a method of transmitting a collective perception message (CPM) at a vehicle-to-everything (V2X) communication apparatus of a vehicle. A method of transmitting V2X message of a vehicle includes generating a collective perception (CP) message including information on a plurality of objects detected by the vehicle, determining whether to fragment the CP message depending on whether a size of the CP message is greater than a predefined size, fragmenting the CP message based on the plurality of detected objects, upon determining that the CP message is fragmented, and transmitting the fragmented CP messages. Each of the fragmented CP messages comprises at least one of header information, information on the vehicle or sensor information used to detect the plurality of objects, which is included in the CP message.

Dependent claims

A method of transmitting a vehicle-to-everything (V2X) message of a vehicle, the method comprising:

detecting a plurality of objects using at least one sensor;
generating a collective perception (CP) message including information related to the plurality of objects detected by the vehicle,
wherein the plurality of objects includes a first object set and a second object set;
determining the first object set and the second object set from the plurality of objects based on a size of the CP message being greater than a predefined size;
generating a first fragmented CP message that includes information related to the first object set and a second fragmented CP message that includes information related to the second object set;
and
transmitting the first fragmented CP message and the second fragmented CP message,
wherein each of the first fragmented CP message and the second fragmented CP message comprises at least one of header information, information on the vehicle or sensor information used to detect the plurality of objects, which is included in the CP message,
wherein the first object set and the second object set are classified based on at least one of:
positions or distances of the plurality of objects,
a latitudinal or longitudinal directions of the plurality of objects determined based on a specific position of the vehicle,
comparison distances between the vehicle and the plurality of objects with a specific threshold and fragmenting the CP message, or
movement directions of the vehicle and the plurality of objects,
wherein the vehicle is capable of performing a V2X communication,
wherein the vehicle is included in an intelligent transport system (ITS),
wherein the V2X communication comprises communication between the vehicle and another vehicle, or between the vehicle and a road side unit (RSU), and
wherein the vehicle is implemented based on an architecture that includes an application layer, a facilities layer, an access layer, a network and a transport layer.
