Patent attributes
A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, an electric actuator configured to actuate the derailleur, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body upon determining the derailleur has been actuated with the electric actuator to change the transmission ratio and a predetermined condition related to pedaling is satisfied. The electronic controller is configured to control the electric actuator so as not to change the transmission ratio until a first condition related to shifting is satisfied in a case where the derailleur is actuated.
