Abstract: A human-powered vehicle control device controls the transmission 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 suppress the change of the transmission ratio as compared with if the electronic controller is in the first control state, in accordance with at least one of the motion state of the body of the human-powered vehicle, the steering state of the human-powered vehicle, the surface conditions 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 includes an electronic controller for controlling a transmission that changes a ratio of a rotational speed of a drive wheel to a rotational speed of a crank of the human-powered vehicle. The electronic controller switches the transmission from a first control state to a second control state in accordance with at least one of a human drive force, a rider's posture, a vehicle body attitude, a handle force, and a human-powered vehicle travel state, In the first control state, the electronic controller controls the transmission to change the ratio in accordance with an operation of a shift operating unit. In the second control state, irrespective of the operation of the shift operating unit, the electronic controller controls the transmission such that the ratio increases in accordance with the travel state of the human-powered vehicle and/or a travel environment of the human-powered vehicle.

Abstract: A suspension control system is provided for a suspension of a human-powered vehicle. The suspension control system basically includes a detector, an electronic controller and an additional detector. The detector is configured to detect information relating to a running condition of the human-powered vehicle indirectly indicative of a pedaling state of the human-powered vehicle. The electronic controller is configured to output a control signal to adjust an operating state of the suspension in accordance with the information detected by the detector. The additional detector is configured to detect additional information relating to at least one of a riding posture of rider riding the human-powered vehicle and a terrain condition. The electronic controller is configured to output the control signal to adjust the operating state of the suspension in accordance with the information in combination with the additional information.

Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission device to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle. The controller controls the transmission device between first, second, and third control states. The controller controls the transmission device in the first control state for a predetermined period in a case where the human-powered vehicle starts to travel until a vehicle state becomes a predetermined state. The controller switches from the first to the second control state if the vehicle state becomes the predetermined state. The controller switches from the first to the third control state if a human driving force input to the human-powered vehicle becomes greater than a predetermined driving force during the predetermined period. Shifting of the ratio is more restricted in the first control state than the second and third control states.

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.
