Zusammenfassung:To provide means for improving certainty by managing changes in the communication status of a travel direction of a moving body and dynamically updating the number of times of transmission by a traffic control system based on the number of times a vehicle has received data from the traffic control system and the future communication status.SOLUTION: A control system, which allows a traffic control system and a vehicle to communicate wirelessly, includes a dynamic redundant communication unit that continuously transmits the same transmission data generated by a traffic control unit multiple times during a part of a transmission cycle. The vehicle includes: a reception count aggregation unit that receives transmission data from the traffic control system, aggregates the number of times the data have been received, and communicates the aggregated number of times the data have been received to the dynamic redundant communication unit; and a vehicle control unit that controls the vehicle using the transmission data received by the reception count aggregation unit. The dynamic redundant communication unit determines, based on the number of times the data have been received, the number of times of transmission for sending within the transmission cycle to satisfy a target arrival rate required by the control.SELECTED DRAWING: Figure 1 【課題】移動体の進行方向の通信状態の変化を管理し、車両が管制から受信したデータの受信回数と、今後の通信状態に応じて、管制が送信回数を動的に更新することで、確実性を向上させる手段を提供する。【解決手段】管制システムと車両が無線で通信する制御システムであって、管制システムは、管制制御部において作成した同一の送信データを送信周期の一部期間内に複数回連続送信する動的冗長通信部を備え、車両は、管制システムからの送信データを受信して受信回数を集計し、集計した受信回数を動的冗長通信部に連絡する受信回数集計部と、受信回数集計部で受信した送信データにより車両を制御する車両制御部とを備え、動的冗長通信部は、受信回数に基づいて、制御が要求する目標到達率を満たすように送信周期内で送信する前記送信回数を決定することを特徴とする制御システム。【選択図】図1
