Abstract
A control device includes an electronic controller configured to control a transmission device of a human-powered vehicle in accordance with a shifting condition. The electronic controller is configured to monitor a torque applied to the human-powered vehicle upon determining the human-powered vehicle is ridden and driven. The electronic controller is configured to permit a shifting operation of the transmission device in accordance with a peak value of the torque upon determining the shifting condition is satisfied.
Claims14
A control device comprising:
- an electronic controller configured to control a transmission device of a human-powered vehicle in accordance with a shifting condition,
- the electronic controller being configured to monitor a torque applied to the human-powered vehicle upon determining the human-powered vehicle is ridden and driven,
- the electronic controller being configured to acquire a peak value of the torque, using the torque monitored while the human-powered vehicle is being ridden and driven, upon determining that the shifting condition has been satisfied, and
- the electronic controller being configured to permit a shifting operation of the transmission device based on a relationship between the torque applied to the human-powered vehicle and the peak value of the torque.
A control device configured to control a transmission device of a human-powered vehicle, the human-powered vehicle including a crank, a wheel, a driving rotation body rotated as the crank rotates, a driven rotation body provided on the wheel, a linking member wound around the driving rotation body and the driven rotation body, and the transmission device, wherein the transmission device moves the linking member between a first rotation body and second rotation body provided on at least one of the driving rotation body and the driven rotation body, the control device comprising:
- an electronic controller configured to monitor a torque applied to the human-powered vehicle upon determining the human-powered vehicle is ridden and driven,
- the electronic controller being configured to acquire a peak value of the torque, using the torque monitored while the human-powered vehicle is being ridden and driven, and
- the electronic controller being configured to control the transmission device so that movement of the linking member from one of the first rotation body and the second rotation body to the other one of the first rotation body and the second rotation body is completed at a timing that differs from the peak value of the torque.
A control device configured to control a transmission device of a human-powered vehicle, the human-powered vehicle including a crank, a wheel, a driving rotation body rotated as the crank rotates, a driven rotation body provided on the wheel, a linking member wound around the driving rotation body and the driven rotation body, and the transmission device, wherein the transmission device moves the linking member between a first rotation body and second rotation body provided on at least one of the driving rotation body and the driven rotation body, the control device comprising:
- an electronic controller configured to monitor a torque applied to the human-powered vehicle upon determining the human-powered vehicle is ridden and driven,
- the electronic controller being configured to acquire a peak value of the torque, using the torque monitored while the human-powered vehicle is being ridden and driven, and the electronic controller being configured to control a timing for starting operation of the transmission device in accordance with at least one of a communication time of a control signal to the transmission device, an operation time of the transmission device, and a movement time of the linking member resulting from operation of the transmission device, and
- the communication time of the control signal to the transmission device, the operation time of the transmission device, and the movement time of the linking member resulting from operation of the transmission device being stored in advance.
