AERODYNAMIC CHARACTERISTICS ESTIMATION DEVICE, AERODYNAMIC CHARACTERISTICS ESTIMATION METHOD, AND PROGRAM

摘要

An aerodynamic characteristic estimation device efficiently finds aerodynamic drag information for a bicycle being ridden by a cyclist from results of detecting force acting on a pedal fitted to the bicycle and of detecting a velocity of the bicycle. Namely the aerodynamic characteristic estimation device is provided with a detection section to detect at least one of a velocity of the-bicycle or an acceleration of the bicycle when being pedaled by a cyclist, a detection section to detect a pedaling power when being pedaled, and an estimation section to estimate aerodynamic drag information indicating an aerodynamic characteristic acting on the bicycle being ridden by the cyclist based on a computation result of mechanical analysis according to an equation of motion established for a direction of progress of the bicycle and using the velocity of the bicycle and the acceleration of the bicycle as obtained from a detection result together with the pedaling power as detected by the detection section.
