To improve a technique for determining air leakage of a tire.SOLUTION: A leakage monitoring device for monitoring air leakage in a tire, includes a communication unit and a control unit. The communication unit is capable of receiving internal pressure information indicating internal pressures of a plurality of tires mounted on a vehicle. The control unit divides a plurality of tires mounted on the vehicle into a plurality of groups. The control unit acquires an internal pressure of each tire via the communication unit during traveling of the vehicle and estimates an internal temperature of each tire, based on the internal pressure. The control unit compares the estimated internal temperatures of the plurality of tires belonging to the same group to determine whether or not there is a possibility of the occurrence of air leakage in any of the tires.SELECTED DRAWING: Figure 1

    【課題】タイヤの空気漏れを判定する技術を改善する。【解決手段】本開示のリーク監視装置は、タイヤの空気漏れを監視するリーク監視装置であって、通信部と制御部とを含む。通信部は、車両が装着する複数のタイヤの内圧を示す内圧情報を受信可能である。制御部は、車両が装着する複数のタイヤを複数のグループにグループ分けする。制御部は、車両の走行中に、それぞれのタイヤについて通信部を介して内圧を取得し、該内圧に基づいてそれぞれのタイヤの内部温度を推定する。制御部は、同一のグループに属する複数のタイヤの推定された内部温度を比較することにより、何れかのタイヤに空気漏れが発生している可能性の有無を判定する。【選択図】図1
