摘要： A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

摘要： 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 changes a motor control state from a third control state to a fourth control state when the first ratio is changed by the transmission or a signal is received for changing the first ratio. The controller changes the motor control state from the fourth control state to a fifth control state in accordance with a value related to at least one of a speed of the human-powered vehicle, the human drive force, an inclination angle of the human-powered vehicle, and a state of a rider of the human-powered vehicle.

摘要： A gearbox may include a drive spindle and several interconnected gear clusters arranged in a housing. A first of the gear clusters is coaxially fastened to the spindle, and has an outboard gear and an inboard gear. The first gear cluster drives a belt to operate one or more of the other gear clusters, and the inboard gear is physically divided into a plurality of segments. A shifting system for the gearbox includes an actuator configured to urge the segments of the inboard gear of the first gear cluster into and out of the plane of the belt, such that a gear ratio of the gearbox is changeable without displacing the belt out of the plane.

摘要： A bicycle control system may be provided to control a first gear changer with a control unit and a second gear changer with the first gear changer. The control unit may control both first and second gear changers. The system includes a predetermined shift path and may transition in and out of the predetermined shift path responsive to various controls. Shifts out of the predetermined shift path may be recovery shifts where both first and second gear changers are controlled.

摘要： A method for actuating a bicycle electronic gearshift comprising the steps of: receiving a signal indicative of the heart rate of a cyclist using the bicycle; receiving a signal indicative of the power delivered by the cyclist; calculating a performance index as a function of the value of the signal indicative of the power and of the value of the signal indicative of the heart rate; obtaining a reference value for the performance index; comparing the calculated performance index with the reference value of the performance index; and, emitting a control signal as a function of the outcome of comparing step. A bicycle electronic system for practicing the disclosed method comprises an electronic gearshift, a heart rate monitor, a power sensor, and a controller configured to carry out each step of the method.
