Abstract:
1. Method for electronically controlling a bicycle gearshift, comprising the steps of: a) detecting, by a controller, a first actual command value of an actuator such as to position a motion transmission chain in engagement with a first of at least three coaxial toothed wheels, and a second actual command value of the actuator such as to position the chain in engagement with a second of said at least three coaxial toothed wheels, b) for each of said at least three coaxial toothed wheels, determining a nominal command value of the actuator theoretically such as to position the chain in engagement with said each one of said at least three coaxial toothed wheels, and c) computing at least a third actual command value of said actuator at least for each of said at least three coaxial toothed wheels other than the first and second toothed wheel, based on said nominal command values and on said first and second actual command value.
