For example, the processor 910 acquires the unique ID of at least one other vehicle through the blinking communication participation pattern, and another corresponding to the unique ID in the blinking communication capability information table stored in the memory 950 through V2X communication. It is possible to obtain vehicle location information. According to one embodiment, the processor 910 is based on the unique identification information and/or location information of at least one other vehicle irradiated with light according to the blinking communication participation pattern, the role of the own vehicle and the at least one other vehicle, and data transmission and reception You can decide the timing. The operation of determining the roles of the own vehicle and the at least one other vehicle may include an operation of determining a transmission/reception relationship between the respective vehicles to establish a blinking communication link between the respective vehicles. For example, as shown in FIG. 17 , when the other car 1 ( 1711 ), the second car 2 ( 1712 ), and the third car 3 ( 1713 ) try to participate in the blinking communication of the own car 1701 , the own car 1701 is the other car Based on the location information of the first vehicle 1711 , the second vehicle 1712 , and the third vehicle 1713 , a data transmission/reception relationship and data transmission/reception timing between the vehicles may be determined. For example, the processor 910 receives the response pattern from the other vehicle 1 1711 after the host vehicle 1701 transmits the blinking pattern corresponding to the data to the other vehicle 1 1711, and the other vehicle 1 1711 transmits the second vehicle 2 ( After delivering the blinking pattern corresponding to the data to 1711), receiving a response pattern from the second vehicle 1712, the second vehicle 1711 transmits the blinking pattern corresponding to the data to the third vehicle 1713, and then the third vehicle 1713. ) may decide to receive a response pattern from After the third vehicle 1713 transmits the blinking pattern corresponding to the response data to the second vehicle 1712, the processor 910 receives the response pattern from the second vehicle 1712, and the second vehicle 1712 transmits the second vehicle 1 ( After transmitting the blinking pattern corresponding to the response data to 1711), receiving the response pattern from the other car 1 1711 (1760), the other vehicle 1 1711 delivers the blinking pattern corresponding to the response data to the own vehicle 1701 , it may be determined to receive a response pattern from the own vehicle 1701 . The response pattern may be an ACK pattern indicating that the blinking pattern corresponding to the data has been normally received. According to an embodiment, when a plurality of vehicles intend to participate in blinking communication, the processor 910 may divide the plurality of vehicles into a plurality of clusters so that the waiting time for each of the plurality of vehicles for blinking communication is minimized. For example, the processor 910 may configure the own vehicle and at least one other vehicle to form a plurality of clusters based on unique identification information and/or location information of each of the plurality of other vehicles irradiated with light according to the blinking communication participation pattern. role and data transmission/reception timing can be determined. For example, as shown in FIG. 18 , in the host vehicle 1801 , some vehicles 1802 , 1803 , 1804 form a first cluster 1831 among a plurality of vehicles irradiated with light according to a blinking communication participation pattern. , a cluster of each vehicle such that some other vehicles 1805 , 1806 , 1807 form a second cluster 1832 , and some other vehicles 1808 , 1809 , 1810 form a third cluster 1833 . and determine the role and transmission/reception timing of each vehicle. At this time, since the vehicles belonging to the first cluster 1831 and the third cluster 1833 are located adjacent to each other, the vehicles of the first cluster 1831 and the vehicles of the third cluster 1833 transmit data at different timings. Since the transmission/reception timing is determined to transmit/receive, and vehicles belonging to the first cluster 1831 and the second cluster 1832 are not located adjacent to each other, the transmission/reception timing may be determined to transmit/receive data at the same timing. According to an embodiment, one vehicle may be included in one or more clusters.

When wireless communication through the communication transceiver 940 is possible, the electronic device 900 of the vehicle may transmit a signal corresponding to a specified event through the communication transceiver 940 in operation 1611 . For example, the processor 910 may determine an external device to communicate with based on the designated event, and transmit a signal indicating that the designated event occurs to the determined external device through the communication transceiver 940 . For example, when the designated event is a pedestrian accident occurrence event, the processor 910 determines that communication with a control center that manages an emergency situation related to a pedestrian accident is required, and the emergency situation due to a pedestrian accident is transmitted through the communication transceiver 940 . A signal indicating the occurrence may be transmitted to the emergency management control center.
