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.
Claims10
A method of transmitting a message of a vehicle, the method comprising:
- detecting surrounding objects;
- determining a preset trigger condition of a safety message is satisfied;
- generating, based on the preset trigger condition for the safety message being satisfied, the safety message;
- grouping the surrounding objects into a vehicle group and a VRU (Vulnerable road user) group;
- determining a transmission interval of the vehicle group and a transmission interval of the VRU group;
- selecting a transmission interval of the safety message among the transmission interval of the vehicle group and the transmission interval of the VRU group;
- and
- transmitting, based on the transmission interval of the safety message, the safety message.
A communication device of a vehicle comprising:
- a memory configured to store data;
- a transceiver configured to transmit and receive a radio signal including a safety message;
- and
- a processor configured to control the memory and the transceiver,
- wherein the processor is configured to:
- detect surrounding objects;
- determine a preset trigger condition for a safety message is satisfied;
- generate, based on the preset trigger condition for the safety message being satisfied, the safety message;
- group the surrounding objects into a vehicle group and a VRU (Vulnerable road user) group;
- determine a transmission interval of the vehicle group and a transmission interval of the VRU group;
- select a transmission interval of the safety message among the transmission interval of the vehicle group and the transmission interval of the VRU group;
- and
- transmit, based on the transmission interval of the safety message, the safety message.
