Abstract: A human-powered vehicle control device is provided for controlling a human-powered vehicle. The human-powered vehicle control device includes an electronic controller that controls a human-powered vehicle component in accordance with a control state including first and second modes. The electronic controller changes a transmission ratio of a transmission device in accordance with a first shifting condition in the first mode, and changes the transmission ratio in accordance with a second shifting condition in the second mode. The electronic controller changes the first shifting condition in accordance with a converging reference value, which is related to a traveling state of the human-powered vehicle, for a case where the human-powered vehicle is in a riding converging state in the first mode, and changes the second shifting condition in accordance with a converging reference value for a case where the human-powered vehicle is in the riding converging state in the second mode.

Abstract: A human-powered vehicle control device controls the transmission to initiate a shifting operation based on a set of prescribed conditions that changes the transmission ratio of a human-powered vehicle. The control device includes an electronic controller that switches between a first control state for controlling the transmission to change the transmission ratio in accordance with a first prescribed set of conditions, and a second control state for controlling the transmission to prevent the change of the transmission ratio as compared with if the electronic controller is in the first control state. The electronic controller switches between the first control state and the second control state in accordance with a detection of at least one of a steering state of the human-powered vehicle, a surface condition of a travel path on which the human-powered vehicle travels, and a pedaling preparation state related to the pedals of the human-powered vehicle.

Abstract: A human-powered vehicle control device is for a human-powered vehicle. The human-powered vehicle includes a motor that applies a propulsion force to the human-powered vehicle and a shifting device that changes a transmission ratio, which is a ratio of a rotational speed of a wheel of the human-powered vehicle to a rotational speed of a crank of the human-powered vehicle. The human-powered vehicle control device includes an electronic controller that is configured to control the shifting device to change the transmission ratio in accordance with a comparison of a first parameter related to the human-powered vehicle and a predetermined threshold value. In a case where an output of the motor decreases as a vehicle speed of the human-powered vehicle increases, the electronic controller is configured to change the predetermined threshold value.
