以提供消耗电力比以往少的路面信息收集装置为课题,在本公开的路面信息收集装置(10)中,以第一采样周期(S1)和比该第一采样周期(S1)短的第二采样周期(S2)对加速度传感器(13)受到的加速度进行采样。并且,基于以第一采样周期(S1)采样得到的第一采样数据的变化来运算加速度传感器(13)的旋转位置,以加速度传感器(13)位于包括轮胎(92)的接地部分的背侧位置的第一规定范围(L1)内为条件之一,以较短的第二采样周期(S2)对加速度传感器(13)的检测结果进行采样而取得第二采样数据。

    A road surface information collection device that consumes less power than conventional counterparts is provided. The road surface information collection device 10 according to the present disclosure samples the acceleration applied to an acceleration sensor 13 with a first sampling cycle S1, and a second sampling cycle S2 that is shorter than that. A rotational position of the acceleration sensor 13 is computed based on changes in first sampling data obtained by the sampling performed with the first sampling cycle S1, and detection results of the acceleration sensor 13 are sampled with the second sampling cycle S2 based on a condition that the acceleration sensor 13 is positioned within a first predetermined range L1 including a back side of a point on a tire 92 in contact with a ground to obtain second sampling data.
