Abstract

Disclosed are a vehicular electronic device and an operation method thereof. The device includes a processor configured to acquire data of a situation of a vehicle, to determine whether the vehicle is a platooning vehicle based on the data, and to determine any one of vehicles in the group as a representative vehicle that transmits a basic safety message (BSM) as a representative of the group upon determining that the vehicle is the platooning vehicle. Data generated by the vehicular electronic device is transmitted to an external device using a 5G communication method. According to the present disclosure, an electronic device of an autonomous vehicle is associated or fuses with a device related to an artificial intelligence module, an unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, a 5G service, or the like.

First claim

What is claimed is:

1. An operation method of a vehicular electronic device, the method comprising:
acquiring information on a state of use of a communication resource of each vehicle in a group of vehicles that are platooning, via vehicle to vehicle (V2V) communication using a communication device by at least one processor; and
acquiring information on a transmission range of a basic safety message (BSM) of each vehicle in the group, via V2V communication using the communication device by the at least one processor,
determining, by the at least one processor, a first vehicle having a smallest usage amount of the communication resource among the vehicles in the group;
determining, by the at least one processor, whether the vehicles in the group include a second vehicle having a usage amount of the communication resource that is equal to or greater than the usage amount of the communication resource of the first vehicle by a specific value;
based on lack of the second vehicle in the group, controlling, by the at least one processor, the first vehicle to transmit a BSM as a representative of the group;
based on the vehicles in the group including the second vehicle, determining, by the at least one processor, a widest transmission range from the acquired information on the transmission range of the BSM of each vehicle, the widest transmission range including a reference range determined based on the transmission ranges of the BSM of the first and second vehicles; and
based on the vehicles in the group including the second vehicle, controlling, by the at least one processor, a vehicle in the group having the widest transmission range of the BSM to transmit the BSM as a representative of the group.

2. The method of claim 1 , further comprising:
identifying, by the at least one processor, a current representative vehicle that transmits the BSM as the representative of the group;
determining, by the at least one processor, a usage amount of the current representative vehicle based on the acquired information on the state of use of the communication resource; and
based on the usage amount of the current representative vehicle increasing to a reference value or greater, controlling, by the at least one processor, a vehicle having a smallest usage amount of the communication resource to transmit the BSM as the representative of the group except for the current representative vehicle among the vehicles in the group.

3. The method of claim 1 , further comprising:
based on a line of the group being changed along with a change in a number of lanes in which platooning is performed, controlling a specific vehicle for each line of the group to transmit the BSM as a representative of each line of the group; and
based on a line of the group being changed as a vehicle outside the group enters the group, controlling, by the at least one processor, a vehicle of the group adjacent to the vehicle outside the group to separately transmit the BSM.

4. The method of claim 1 , further comprising:
based on a vehicle outside the group attempting to enter the group, controlling, by the at least one processor, a vehicle of the group adjacent to the vehicle outside the group to separately transmit the BSM; and
based on a plurality of vehicles outside the group approaching the group, where a ratio of a number of vehicles among the plurality of vehicles outside the group positioned within a preset distance from the group to a number of the vehicles in the group is equal to or greater than a preset ratio, controlling, by the at least one processor, each vehicle in the group to separately transmit the BSM.

5. The method of claim 4 , further comprising:
based on the plurality of vehicles outside the group approaching the group, controlling the vehicle transmitting the BSM to stop transmission of the BSM as the representative of the group.
