Method for electronically controlling a bicycle gearshift and bicyle electronic system
First Claim
1. Method for carrying out a multiple gearshifting in a bicycle gearshift, comprising the steps of:
- a) providing an electronic control unit that transmits at least a first and a second single gearshifting request,b) providing a driving unit that receives the first and second single gearshifting requests, and actively monitors the passing of time associated with a deliberate waiting time period, andc) the driving unit moves a chain of the gearshift between two adjacent toothed wheels to carry out a first single gearshifting, and carries out a second execution of this step c) for a second single gearshifting after the deliberate waiting time period.

Abstract
A method for electronically controlling a bicycle gearshift and a bicycle electronic system, wherein when a gearshifting request is transmitted from an electronic control unit to a driving unit, the driving unit associates a wait for a waiting time therewith. In the case of a multiple gearshifting, the waiting time allows a chain to mesh securely with a toothed wheel. By providing for the wait to be carried out in a driving unit of a derailleur, the computing capability of an electronic control unit is not affected by the management of the wait, and the electronic control unit is free to carry out other functions, for example the management of errors of the electronic system, communication with a display unit or various sensors of the electronic system, etc.
