DEVICE FOR DETERMINING THE ANGULAR SPEED OF A BICYCLE WHEEL AND THE PEDALING CADENCE APPLIED TO THE PEDALS OF SAID BICYCLE

摘要

A device (1) for determining a cinematic magnitude of a bicycle and a rate of the pedal- thrust exerted by an user on the pedals of said bicycle comprises: - a sensor (2) of said cinematic magnitude of the bicycle, adapted to be associated to said bicycle, suitable for detecting said bicycle cinematic magnitude (ωi) and for generating a signal representative of said bicycle cinematic magnitude; - a filter (13) connected to said sensor (6) of the bicycle cinematic magnitude, configured for receiving at the input said signal representative of the bicycle cinematic magnitude (ωi) and for supplying, at the output, an optimized signal (ωopt) of the bicycle cinematic magnitude obtained by eliminating from the signal representative of the bicycle cinematic magnitude (ωi), estimated errors (ϑi) correlated to the structure of said sensor of the bicycle cinematic magnitude; - a module (15) for the frequency-analysis of said optimized signal (ωopt) of the bicycle cinematic magnitude, connected to said filter (13), configured for determining said pedal-thrust rate based on the frequency-analysis of said optimized signal (ωopt) of the bicycle cinematic magnitude and for supplying a signal representative of the pedal-thrust rate (C).
