An aerodynamic characteristics estimation device efficiently obtains air resistance information of a bicycle on which a cycler is riding from a detection result including the detected speed of the bicycle and force applied to pedals attached to the bicycle. Specifically, the aerodynamic characteristics estimation device is provided with: a detection unit which detects the speed of a bicycle and/or the acceleration of the bicycle during pedaling; a detection unit which detects pedaling force during pedaling; and a calculation unit which estimates, using the speed of the bicycle and the acceleration of the bicycle obtained from a detection result and the pedaling force detected by the pedaling force detection unit, air resistance information indicating aerodynamic characteristics acting on the bicycle on which a cycler is riding, on the basis of a calculation result of dynamics analysis according to an equation of motion that is satisfied with respect to the direction of travel of the bicycle.

    空气动力特性估计装置根据对装备于自行车的踏板施加的力以及检测出自行车的速度的检测结果,高效地求出骑车人骑乘中的自行车的空气阻力信息。即,空气动力特性估计装置具备:检测部,其检测踩踏板时的自行车的速度和自行车的加速度中的至少一方;检测部,其检测踩踏板时的踏力;以及运算部,其使用从检测结果获得的自行车的速度及自行车的加速度、以及由踏力检测部检测出的踏力,基于利用在自行车的行进方向上成立的运动方程进行的力学分析的运算结果,来估计空气阻力信息,该空气阻力信息表示作用于骑车人骑乘中的自行车的空气动力特性。
