PROBLEM TO BE SOLVED: To provide a tire air pressure estimating device capable of appropriately estimating tire air pressure.SOLUTION: A tire air pressure estimating device comprises: an imaging target formed on an inner surface of a tire of a vehicle; an imaging unit provided in a wheel into which the tire is fitted and imaging the imaging target on the inner surface of the tire; an air pressure estimating unit which estimates air pressure of the tire; a rotation state recognizing unit which recognizes a rotation state of the tire on the basis of detection results of a rotation position of the tire; and an imaging timing control unit which controls an imaging timing of the imaging target by the imaging unit on the basis of the rotation state of the tire.SELECTED DRAWING: Figure 5
【課題】適切にタイヤの空気圧の推定を行うことができるタイヤ空気圧推定装置を提供する。【解決手段】車両のタイヤの内面に形成された撮像ターゲットと、タイヤが嵌め込まれたホイールに設けられ、タイヤの内面の撮像ターゲットを撮像する撮像部と、撮像部の撮像した撮像ターゲットに基づいて、タイヤの空気圧を推定する空気圧推定部と、タイヤの回転位置の検出結果に基づいて、タイヤの回転状況を認識する回転状況認識部と、タイヤの回転状況に基づいて、撮像部による撮像ターゲットの撮像タイミングを制御する撮像タイミング制御部と、を備える。【選択図】図5
