Abstract: A human-powered vehicle control device includes an electronic controller configured to control a motor to drive a transmission body with the motor and operate the transmission body with a derailleur to perform a shifting action that changes the transmission ratio in a case where a crank axle is stopped. The electronic controller includes a first control state in which the shifting action is performed and a second control state in which a driving force of the motor during the shifting action is reduced compared to the first control state. The electronic controller shifts the control state to the second control state in a case where a rider is riding the human-powered vehicle and the human-powered vehicle is stopped. The electronic controller shifts the control state from the second control state to the first control state in a case where a predetermined condition is satisfied.

Abstract: 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.

Abstract: A control data creation device is provided that has an acquisition part, a creation part and an evaluation part. The acquisition part acquires input information concerning traveling of a human-powered vehicle. The creation part creates by a learning algorithm a learning model that outputs output information concerning control of a component of the human-powered vehicle based on input information acquired by the acquisition part. The evaluation part evaluates output information output from the learning model. The creation part updates the learning model based on training data including an evaluation by the evaluation part, input information corresponding to an output of the output information and the output information.

Abstract: A creation device is provided that has at least one processor operatively coupled to non-transitory computer readable storage to execute operations that includes an acquisition part and a creation part. The acquisition part acquires input information concerning traveling of a human-powered vehicle. The creation part uses a learning algorithm to create a learning model that outputs output information concerning control of the components of the human-powered vehicle based on the input information.
