To provide a device which accurately obtains a steering angle of a tire of a vehicle.SOLUTION: An on-vehicle device mounted on a vehicle comprises: an image acquisition unit which acquires an image by a camera photographing the front side or rear side of the vehicle; a steering angle acquisition unit which acquires a steering angle by a steering angle sensor for detecting the steering angle of a steering wheel of the vehicle; a storage unit which stores correspondence data indicating a correspondence between the steering angle and the steering angle of the tire of the vehicle and the maximum steering angle being the steering angle at which the steering angle of the tire becomes the maximum; and a control unit which acquires the steering angle of the tire of the vehicle with respect to the steering angle on the basis of the steering angle and the correspondence data when the steering angle acquired by the steering angle acquisition unit is less than the maximum steering angle, acquires the steering angle of the tire of the vehicle with respect to the maximum steering angle when the steering angle acquired by the steering angle acquisition unit is equal to or greater than the maximum steering angle, and outputs to a display unit a combined image in which a prediction image indicating a route of the vehicle according to the calculated steering angle of the tire is superimposed on the image of the front side or rear side captured by the camera.SELECTED DRAWING: Figure 1

    【課題】車両のタイヤの舵角を精度よく求める装置を提供する。【解決手段】車両に搭載される車載装置であって、車両の前方又は後方を撮影するカメラより画像を取得する画像取得部と、車両のステアリングホイールの操舵角を検出する操舵角センサより操舵角を取得する操舵角取得部と、操舵角と車両のタイヤの舵角との対応関係を示す対応関係データと、タイヤの舵角が最大となる前記操舵角である最大操舵角とを格納する記憶部と、操舵角取得部が取得した操舵角が最大操舵角未満である場合、操舵角と対応関係データとに基づいて、操舵角に対する車両のタイヤの舵角を取得し、操舵角取得部が取得した操舵角が最大操舵角以上である場合、最大操舵角に対する車両のタイヤの舵角を取得し、算出されたタイヤの舵角に応じた車両の進路を示す予測画像を、カメラが撮影した前方又は後方の画像に重ねた合成画像を表示部へ出力する制御部と、を備える車載装置とする。【選択図】図1
