Abstract: A control device for a human-powered vehicle includes an electronic controller. The human-powered vehicle includes a crank axle that receives a human driving force, a first rotational body connected to the crank axle, a wheel, a second rotational body connected to the wheel, a transmission body engaged with the rotational bodies to transmit a driving force between the rotational bodies, a derailleur that operates the transmission body to shift a transmission ratio, and a motor that drives the transmission body. The electronic controller controls the motor to drive the transmission body with the motor without propelling the human-powered vehicle with the driving force of the motor in a case where a first condition in which the crank axle is rotated and the human-powered vehicle is propelled without the human driving force and a shifting condition for shifting the transmission ratio with the derailleur are satisfied.

Abstract: A human-powered vehicle control device controls the transmission that changes the transmission ratio of a human-powered vehicle. The control device includes an electronic controller that switches between a first control state for controlling the transmission to change the transmission ratio in accordance with a first prescribed set of conditions, and a second control state for controlling the transmission to suppress the change of the transmission ratio as compared with if the electronic controller is in the first control state, in accordance with at least one of a steering state of the human-powered vehicle, a surface condition of a travel path on which the human-powered vehicle travels, and a pedaling preparation state related to the pedals of the human-powered vehicle.

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 control device for a human-powered vehicle includes an electronic controller configured to control a motor, which applies a propulsion force to a human-powered vehicle, in correspondence with a human driving force input to the human-powered vehicle. The electronic controller is configured to control the motor so as to increase an assist force produced by the motor for when an output of the motor is maximal upon determining a parameter related to at least one of a vehicle speed of the human-powered vehicle, an inclination angle of the human-powered vehicle, and a travel resistance of the human-powered vehicle has increased.

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.
