    摘要: 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, 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 with the motor upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied, and control the motor to increase a rotational speed of the motor as a difference of a first rotational speed, which is calculated in correspondence with a rotational speed of the wheel and the transmission ratio, and a predetermined rotational speed or a rotational speed in a predetermined range increases.

    摘要: A human-powered vehicle control device includes an electronic controller configured to control a transmission that changes a transmission ratio of a rotational speed of a wheel of a human-powered vehicle to a rotational speed of a crank of the human-powered vehicle. The electronic controller is configured to control the transmission to change the transmission ratio in accordance with a comparison of a parameter related to at least one of a traveling environment and a traveling state of the human-powered vehicle with a predetermined determination value. The electronic controller is configured to change the predetermined determination value in accordance with a change in the parameter during a single rotation of the crank.

    摘要: 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.
