To achieve both improvement in analysis accuracy of acceleration and reduction in power consumption of a sensor.SOLUTION: An instruction device 4 includes: a reception unit 441 that receives acceleration from a sensor 3 provided in a wheel of a vehicle to detect the acceleration of the wheel and transmit the acceleration by wireless communication; and an instruction unit 442 that causes transmission of the acceleration detected by the sensor 3 at a first cycle when the acceleration is equal to or greater than a threshold, and at a second cycle longer than the first cycle when the acceleration is less than the threshold.SELECTED DRAWING: Figure 3
【課題】加速度の解析精度の向上及びセンサの消費電力の低減を両立させる。【解決手段】指示装置4は、車両の車輪に設けられて車輪の加速度を検出して無線通信で送信するセンサ3から加速度を受信する受信部441と、加速度が閾値以上である場合にはセンサ3が検出した加速度を第1周期で送信させて、加速度が閾値未満である場合にはセンサ3が検出した加速度を第1周期よりも長い第2周期で送信させる指示部442と、を有する。【選択図】図3
