Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle in accordance with a control state. In a case where the controller controls the transmission to shift the ratio in accordance with an input from a shift operation device in a first control state, the controller changes the control state to a second control state. In a case where a change amount of a parameter related to a vehicle state of the human-powered vehicle becomes a predetermined amount or greater in the second control state, the controller changes the control state to the first control state. Shifting of the ratio in accordance with a shifting condition is more restricted in the second control state than the first control state.

Abstract: A human-powered vehicle control device includes an electronic controller for controlling a transmission that changes a ratio of a rotational speed of a drive wheel to a rotational speed of a crank of the human-powered vehicle. The electronic controller switches the transmission from a first control state to a second control state in accordance with at least one of a human drive force, a rider's posture, a vehicle body attitude, a handle force, and a human-powered vehicle travel state, In the first control state, the electronic controller controls the transmission to change the ratio in accordance with an operation of a shift operating unit. In the second control state, irrespective of the operation of the shift operating unit, the electronic controller controls the transmission such that the ratio increases in accordance with the travel state of the human-powered vehicle and/or a travel environment of the human-powered vehicle.

Abstract: A human-powered vehicle control device includes an electronic controller that controls a motor. The motor assists in propulsion of a human-powered vehicle including a transmission configured to change, in steps, a first ratio of a rotational speed of a drive wheel to a rotational speed of a rotary body to which human drive force is input. The controller controls the motor in a first control state if the first ratio is changed by only one step during a predetermined period or a signal is received for changing the first ratio by one step during the predetermined period. The controller controls the motor in a second control state that differs from the first control state if the first ratio is changed by at least two steps during the predetermined period or a signal is received for changing the first ratio by at least two steps during the predetermined period.
