description To provide a communication control device capable of securing quality of a digital twin and suppressing increase in communication cost by dynamically changing frequency of communication with a vehicle according to a state of the vehicle.SOLUTION: A communication control device for performing communication with a plurality of vehicles includes: a communication unit configured to perform communication including acquisition of vehicle data with the plurality of vehicles; a database configured to store data for forming a digital twin time-synchronized with a real space in a virtual space based on the vehicle data acquired by the communication unit; and a control unit configured to control a frequency of communication performed by the communication unit. When there is a first vehicle whose distance to a surrounding object is less than a first threshold in the digital twin, the control unit increases the frequency of communication with the first vehicle more than when distance between the first vehicle and the surrounding object is equal to or greater than the first threshold.SELECTED DRAWING: Figure 1 【課題】車両との通信頻度を車両の状況に応じて動的に変化させることによって、デジタルツインの品質を確保すると共に、通信コストの増加を抑制することができる通信制御装置を提供する。【解決手段】複数の車両と通信を行う通信制御装置であって、複数の車両との間で車両データの取得を含む通信を行う通信部と、通信部によって取得された車両データに基づいて、仮想空間上に現実空間と時刻同期したデジタルツインを形成するためのデータを格納するデータベースと、通信部が行う通信の頻度を制御する制御部と、を備え、制御部は、デジタルツイン上で周囲物体との距離が第1閾値未満である第1車両が存在する場合、第1車両と周囲物体との距離が第1閾値以上であるときよりも第1車両との間で行う通信の頻度を増加させる。【選択図】図1
