To estimate air resistance information indicating aerodynamic characteristics acting on a bicycle which is being ridden by a bicycle rider by using a simple configuration.SOLUTION: An aerodynamic characteristic estimation device (10) efficiently determines air resistance information on a bicycle which is being ridden by a bicycle rider on the basis of force applied to pedals mounted to the bicycle and a detection result obtained by detecting speed of the bicycle. The aerodynamic characteristic estimation device (10) includes: a detection section (12) detecting at least one of the speed of the bicycle and acceleration of the bicycle during pedaling; a detection section (14) detecting tread force during pedaling; and a calculation section (16) estimating air resistance information indicting aerodynamic characteristics acting on the bicycle which is being ridden by the bicycle rider, on the basis of a calculation result of a dynamic analysis by a motion equation achieved relative to an advancing direction of the bicycle by using the speed of the bicycle and the acceleration of the bicycle obtained from the detection results and the tread force detected by the tread force detection section.SELECTED DRAWING: Figure 1

    【課題】簡単な構成で、自転車乗員が乗車中の自転車に作用する空力特性を示す空気抵抗情報を推定する。【解決手段】空力特性推定装置(10)は、自転車に装備されたペダルにかかる力、及び自転車の速度を検出した検出結果から自転車乗員が乗車中の自転車における空気抵抗情報を効率的に求める。すなわち、空力特性推定装置(10)はペダリング時における自転車の速度及び自転車の加速度の少なくとも一方を検出する検出部(12)と、ペダリング時における踏力を検出する検出部(14)と、検出結果から得られる自転車の速度、及び自転車の加速度と、踏力検出部で検出された踏力と、を用いて、自転車の進行方向に対して成立する運動方程式による力学解析の演算結果に基づいて、自転車乗員が乗車中の自転車に作用する空力特性を示す空気抵抗情報を推定する演算部(16)と、を備える。【選択図】図1
