A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, an electric actuator configured to actuate the derailleur, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body upon determining the derailleur has been actuated with the electric actuator to change the transmission ratio and a predetermined condition related to pedaling is satisfied. The electronic controller is configured to control the electric actuator so as not to change the transmission ratio until a first condition related to shifting is satisfied in a case where the derailleur is actuated.

A control device includes an electronic controller that controls a motor of a human-powered vehicle. The electronic controller outputs a signal to change a transmission ratio by operating a linking body with a derailleur while driving the linking body with the motor where a first condition related to pedaling is satisfied. The first condition relates to at least one of a pedal state, a human driving force input to the pedal, a crank arm state, a human driving force input to the crank arm, a crank axle angular acceleration, a rotational state of a first rotational body, a tire state, a rotational state of a second rotational body, an operational state of the linking body, an operational state of the derailleur, a rotational state of the motor, an electric energy supplied to the motor, a handlebar state, a saddle state, and positional information of the human-powered vehicle.

A shifting system for a human-powered vehicle comprises a controller. The controller is configured to receive a driving torque and a cadence of the human-powered vehicle from at least one sensor. The controller is configured to determine a permitted shift timing based on the driving torque and the cadence. The controller is further configured to control a shift mechanism to perform a gear shift during the permitted shift timing in accordance with a permitted cadence range and a first threshold of the driving torque.

A human-powered vehicle control device includes an acquisition unit, a first electronic controller, an operation probability output model and a second electronic controller. The acquisition unit is configured to acquire input information related to traveling of a human-powered vehicle. The first electronic controller is configured to decide control data of a device provided at the human-powered vehicle in accordance with a predetermined control algorithm based on the input information acquired and performs automatic control on the device by the control data decided. The operation probability output model outputs a probability of a rider performing an intervening operation on automatic control of the device based on the input information. The second electronic controller is configured to change a parameter for deciding the control data in a case where a probability that is output from the operation probability output model is equal to or more than a predetermined value.

An automatic control method suitable for a bicycle system is provided. The bicycle system has a gear ratio and a toque ratio formed by an auxiliary torque and a pedaling torque. The automatic control method includes following steps: sensing a pedaling cadence and the pedaling torque of the bicycle system in a riding state; setting a first cadence threshold and a second cadence threshold according to a preset pedaling cadence while the first cadence threshold is greater than the second cadence threshold; and determining whether the pedaling cadence is greater than the first cadence threshold or less than the second cadence threshold so as to set to increase or decrease the gear ratio. In addition, a bicycle system suitable for the automatic control method is also provided.
