To provide a technique for suppressing unnecessary communication in communication between a vehicle and a base station and improving frequency utilization efficiency.SOLUTION: A vehicle 2A determines that the content of situation information received from a vehicle 2NG is abnormal and detects the vehicle 2NG as an abnormal vehicle in S101. Subsequently, the vehicle 2A transmits the abnormality information including the identification information of the vehicle 2NG to a base station 3 in S102, and transmits, to other vehicles 2B around the vehicle 2A, reported notification for notifying abnormality information including identification information of the vehicle 2NG which has already transmitted the abnormality information to the base station 3 in S103. The vehicle 2B detects the vehicle 2NG as an abnormal vehicle in S106, but since the vehicle 2B has received the reported notification from the vehicle 2A in S103, the vehicle 2B does not transmits the abnormality information of the vehicle 2NG to the base station 3 as shown in S107.SELECTED DRAWING: Figure 3
【課題】車両と基地局との間の通信において、不要な通信が行われることを抑制し、周波数利用効率を向上させる技術を提供する。【解決手段】S101で、車両2Aは、車両2NGから受信した状況情報の内容を異常と判定し、車両2NGを異常車両として検出する。続いて、車両2Aは、S102で、車両2NGの識別情報を含む異常情報を基地局3へ送信し、S103で、異常情報を基地局3へ送信済みである車両2NGの識別情報を通知する報告済通知を周囲の他の車両2Bへ送信する。車両2Bは、S106で、車両2NGを異常車両として検出するが、S103で車両2Aから報告済通知を受信しているため、S107に示すように、車両2NGの異常情報を基地局3へ送信しない。【選択図】図3
