Bicycle shifting control apparatus and method of controlling derailleur
First Claim
1. A bicycle shifting control apparatus comprising:
- a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal, the chain guide being configured to guide a bicycle chain configured to engage with a sprocket assembly including sprockets having a shift assist structure configured to assist a shifting motion of the bicycle chain,the transmission controller being configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having the shift assist structure prior to completion of the shifting operation of the chain guide.

Abstract
A bicycle shifting control apparatus comprises a transmission controller configured to control a guide actuator of a derailleur to move a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal. The transmission controller is configured to control, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, the guide actuator to temporarily decelerate the chain guide at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having a shift assist structure prior to completion of the shifting operation of the chain guide.

23. A method of controlling a derailleur, comprising:
-
moving a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal, the chain guide being configured to guide a bicycle chain configured to engage with a sprocket assembly including sprockets having a shift assist structure configured to assist a shifting motion of the bicycle chain; and decelerating the chain guide temporarily, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, at a deceleration position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having the shift assist structure prior to completion of the shifting operation of the chain guide.

24. A method of controlling a derailleur, comprising:
-
moving a chain guide of the derailleur between a plurality of shift positions in response to an input shifting signal, the chain guide being configured to guide a bicycle chain configured to engage with a sprocket assembly including sprockets having a shift assist structure configured to assist a shifting motion of the bicycle chain; and stopping the chain guide temporarily, in a shifting operation of the chain guide between adjacent two shift positions of the plurality of shift positions, at a waiting position defined between the adjacent two shift positions so that the bicycle chain engages with and/or disengages from one of the sprockets having the shift assist structure prior to completion of the shifting operation of the chain guide.
