Aerodynamic characteristic estimation device, aerodynamic characteristic estimation method and program

An aerodynamic characteristic estimation method comprising:

• detecting at least one of a velocity of a bicycle or an acceleration of the bicycle when being pedaled by a cyclist;
• detecting a pedaling power when being pedaled by the cyclist;
• and
• estimating 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 at least one of the velocity of the bicycle or the acceleration of the bicycle and the pedaling power, as obtained from results of the detecting.

A non-transitory storage medium storing a program executable by a computer to perform processing to estimate aerodynamic drag information indicating an aerodynamic characteristic acting on a bicycle while being ridden by a cyclist, the processing comprising:

• acquiring at least one of a velocity of the bicycle or an acceleration of the bicycle when being pedaled by a cyclist;
• acquiring a pedaling power when being pedaled by the cyclist;
• and
• estimating 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 at least one of the velocity of the bicycle or the acceleration of the bicycle and the pedaling power, as obtained from results of the acquiring.
