Abstract: A method of transmitting a CPM message by a V2X communication device of a vehicle is disclosed. The method includes detecting at least one surrounding object; based on whether a state of the detected object satisfies a preset trigger condition of a collective perception (CP) message, generating the CP message including information on the detected object; and transmitting the CP message, wherein the CP message is generated when the state of the detected object satisfies the trigger condition, or is generated when the state of the detected object does not satisfy the trigger condition and a specific time has passed after the previously transmitted CP message is generated.
