Bicycle motor control system

摘要

A motor bicycle control system is provided for controlling a motor for assisting rotation of a bicycle wheel. The bicycle motor control system includes a motor communication part and a first mode switching part. The motor communication part performs power line communication with an electrical bicycle component and that changes a motor operation mode of the motor. The first mode switching part is operated either by electrical power supplied via a power line through which the motor communication part performs power line communication, or by electrical power obtained from a generator. The first mode switching part switches the motor operation mode from a motor driving mode in which the motor assist in rotating the bicycle wheel to a motor power generating mode in which the motor outputs electrical power that has been generated using rotation of the bicycle wheel according to a state of communication with the electrical component.

1. A bicycle motor control system for controlling a motor for assisting rotation of a bicycle wheel, the bicycle motor control system comprising:
a motor communication part that performs power line communication with an electrical bicycle component through a common power line used to communicate both electrical power and information; and a motor control part configured to set a motor operation mode of the motor to a motor driving mode or a motor power generating mode in response to a mode switching signal from the electrical bicycle component, the motor driving mode being a mode in which the motor assists in rotating the bicycle wheel and the motor power generating mode being a mode in which the motor outputs electrical power that has been generated using rotation of the bicycle wheel, the motor control part being operated by at least one of electrical power supplied via the common power line and electrical power generated by the motor, the motor control part being configured to determine if a signal is being communicated between the electrical bicycle component and the motor communication part, the motor control part including a first mode switching part that switches the motor operation mode from the motor driving mode to the motor power generating mode upon a determination that a signal is not being communicated between the motor communication part and the electrical bicycle component.
