To provide a wheel position detection device which can perform accurate wheel position detection more quickly.SOLUTION: In order to perform acceleration measurement when a vehicle 1 is turning at a control unit 33, the instruction of measurement start timing Ts and measurement end timing Te is transmitted to each tire side communication apparatus 2a to 2d. In addition, at the control unit 33, a sensor angle α is calculated on the basis of the acceleration Gx and acceleration Gz, and a cumulative angle θ is calculated by accumulating the change in the sensor angle α from the measurement start timing Ts to the measurement end timing Te on the basis of the sensor angle α. Then, at the control unit 33, on the basis of a magnitude of the cumulative angle θ in each tire side communication apparatus 2a to 2d, the wheel to which each tire side communication apparatus 2a to 2d is identified as one of multiple wheels 5a to 5d.SELECTED DRAWING: Figure 1

    【課題】より早くに精度良い車輪位置検出を行うことが可能な車輪位置検出装置を提供する。【解決手段】制御部33にて、車両1が旋回状態の際に加速度計測を行わせるべく、それぞれのタイヤ側通信機2a~2dに対して計測開始タイミングTsと計測終了タイミングTeの指示を伝える。また、制御部33にて、加速度Gxおよび加速度Gzに基づいてセンサ角度αを算出し、センサ角度αに基づき、計測開始タイミングTsから計測終了タイミングTeまでの間のセンサ角度αの変化を累積した累積角度θを算出する。そして、制御部33にて、それぞれのタイヤ側通信機2a~2dにおける累積角度θの大きさに基づいて、それぞれのタイヤ側通信機2a~2dが取付けられた車輪が複数の車輪5a~5dのいずれであるかを特定する。【選択図】図1
