Abstract
A control device includes an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition. The electronic controller is configured to set the shifting condition based on first reference information including information related to change in transmission ratio that is shifted by the transmission device.
Claims22
A control device comprising:
- an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition, the human-powered vehicle including a first sprocket driven to obtain a first transmission ratio and a second sprocket driven to obtain a second transmission ratio,
- the electronic controller being configured to set the shifting condition based on first reference information including information related to a change in a transmission ratio that is shifted by the transmission device, the transmission ratio including the first and second transmission ratio, the information including a combination of the first transmission ratio and the second transmission ratio, the information further including information related to a difference in a number of teeth of the first sprocket and a number of teeth of the second sprocket, and
- the electronic controller further being configured to set setting a threshold value based on the first reference information, wherein the shifting condition is determined based on the threshold value.
A control device according comprising:
- an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition, the human-powered vehicle including a first sprocket driven to obtain a first transmission ratio and a second sprocket driven to obtain a second transmission ratio,
- the electronic controller being configured to set the shifting condition based on first reference information including information related to a combination of the first transmission ratio and the second transmission ratio, the information further including information related to a difference in a number of teeth of the first sprocket and a number of teeth of the second sprocket, and
- the electronic controller further being configured to set a threshold value based on the first reference information, wherein the shifting condition is determined based on the threshold value.
A control device comprising:
- an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition, the electronic controller being configured to set the shifting condition based on first reference information including information related to a change in a transmission ratio that is shifted by the transmission device, the first reference information further including a first reference value including traveling information related to a traveling state of the human-powered vehicle,
- the shifting condition being determined based on a second reference value and a threshold value, and
- the electronic controller being further configured to set the threshold value based on the first reference information.
A control device comprising:
- an electronic controller configured to automatically control a transmission device of a human-powered vehicle in accordance with a shifting condition,
- a first reference value including traveling information related to a traveling state of the human-powered vehicle, the shifting condition being determined based on a second reference value and a threshold value,
- the electronic controller being further configured to set the threshold value based on second reference information including a present transmission ratio of the human-powered vehicle, and a subsequent transmission ratio after shifting.
