  • Patent number: 11001337
    Abstract: A human-powered vehicle control device includes an electronic controller that controls a motor used to assist in propulsion of a human-powered vehicle. The electronic controller is selectively settable to a first control state that controls the motor in accordance with human drive force and a second control state that controls the motor in accordance with human drive force so that a ratio of an output of the motor to the human drive force is greater than that of the first control state. In the first control state, the electronic controller controls the motor so that a response speed of the motor with respect to a change in the human drive force is equal to a first response speed. In the second control state, the electronic controller controls the motor so that the response speed is equal to a second response speed that is slower than the first response speed.

  • Patent number: 10994805
    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.
