  • Patent number: 11952081
    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.
