Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission device to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle in stages. The controller controls the transmission device so that the transmission device performs a first shifting action that shifts the ratio by only one stage in a case where a shifting condition is satisfied. The transmission device is controlled by the electronic controller so that the transmission device performs a second shifting action that shifts the ratio by two or more stages in a case where the shifting condition is satisfied and a vehicle state of the human-powered vehicle is a predetermined state. The predetermined state includes a state in which a change amount of a parameter related to the vehicle state is a predetermined amount or greater.

Abstract: A control device for a human-powered vehicle includes an electronic controller. The human-powered vehicle includes a motor that applies a propulsion force to the human-powered vehicle and a transmission that shifts a transmission ratio of the human-powered vehicle between a plurality of shift stages. The electronic controller is configured to control the motor. The electronic controller is configured to decrease an upper limit value of an output of the motor in an up-shift operation. The electronic controller is configured to decrease the upper limit value in a down-shift operation. The electronic controller is configured to control the motor so that the upper limit value in the up-shift operation performed between two predetermined ones of the shift stages that differ in the transmission ratio by one stage differs from the upper limit value in the down-shift operation performed between the two predetermined ones of the shift stages.

Abstract: A control device for a human-powered vehicle has an electronic controller that controls a motor that applies a propulsion force to the human-powered vehicle to assist a human driving force. The human-powered vehicle includes a transmission device. The electronic controller is configured to assist in propulsion of the human-powered vehicle with the motor in a state in which the human-powered vehicle is propelled by the human driving force. In a case where a transmission ratio of the transmission device is changed, the electronic controller decreases an assist level of the motor in accordance with the human driving force input to the human-powered vehicle, and controls the motor so that the assist level is greater for a case where the human driving force is a first human driving force than the assist level for a case where the human driving force is less than the first human driving force.
