Abstract
A bicycle shifting control apparatus comprises a sensing target, a rotational-position sensing unit, and a transmission controller. The sensing target is rotatable with a sprocket assembly. The rotational-position sensing unit is configured to contact the sensing target to sense a rotational position of the sensing target as the rotational position of the sprocket assembly. The transmission controller is configured to control a derailleur based on the rotational position sensed by the rotational-position sensing unit.
Claims18
A bicycle shifting control apparatus comprising:
- a sensing target rotatable with a sprocket assembly;
- a rotational-position sensing unit configured to contact the sensing target to sense a rotational position of the sensing target as the rotational position of the sprocket assembly;
- and
- a transmission controller configured to control a derailleur based on the rotational position sensed by the rotational-position sensing unit.
A bicycle shifting control apparatus comprising:
- a rotational position sensing unit configured to sense a rotational position of a sprocket assembly configured to be rotatably supported by a housing member configured to be rotatable relative to an axle member, the rotational position sensing unit being provided inside the housing member;
- and
- a transmission controller configured to control a derailleur based on the rotational position sensed by the rotational position sensing unit.
A bicycle shifting control apparatus comprising:
- a sensing target rotatable with a sprocket assembly;
- a rotational position sensing unit configured to sense a rotational position of the sprocket assembly and including an imaging sensor configured to capture a target image of the sensing target;
- and
- a transmission controller configured to calculate a rotational position of the sprocket assembly based on the target image captured by the imaging sensor and configured to control a derailleur based on the rotational position calculated by the transmission controller.
