Abstract
A control device and a transmission system are configured to improve riding comfort of a human-powered vehicle. The control device includes an electronic controller that is configured to control a transmission device of a human-powered vehicle so that a transmission ratio at which the vehicle is started becomes equal to a designated transmission ratio. The electronic controller is configured to set the designated transmission ratio based on reference information that excludes information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle.
Claims40
A control device comprising:
- an electronic controller configured to control a transmission device of a human-powered vehicle;
- and
- a storage that stores a designated transmission ratio in an updateable manner, the designated transmission ratio being a transmission ratio to which the transmission device is controlled by the electronic controller at a time when the human-powered vehicle is stopped so that the transmission device is set to the designated transmission ratio before the human-powered vehicle is started into motion from a stopped state,
- the electronic controller being further configured to
- acquire reference information;
- determine, based on the reference information, whether to maintain the designated transmission ratio or update the designated transmission ratio to be used a next time the vehicle is started,
- execute a control to maintain or update the designated transmission ratio, and
- control the transmission device to the designated transmission ratio at the time when the human-powered vehicle is stopped,
- the reference information excluding information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle.

A control device comprising:
- an electronic controller configured to control a transmission device of a human-powered vehicle so that a transmission ratio at which the vehicle is started becomes equal to a designated transmission ratio;
- the electronic controller being configured to set the designated transmission ratio based on reference information that excludes information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle,
- the reference information including at least one of vehicle stop information related to a stopping state of the human-powered vehicle, riding information related to riding of the human-powered vehicle, rider information related to a rider riding the human-powered vehicle, and environment information related to a riding environment of the human-powered vehicle
- the rider information including fatigue information related to fatigue of the rider, the fatigue information including information related to a rest time, and
- the electronic controller being configured to set the designated transmission ratio so that the transmission ratio at which the vehicle is started is started is decreased upon determining the rest time is shorter than a second rest time.

A control device comprising:
- an electronic controller configured to control a transmission device of a human-powered vehicle;
- and
- a storage that stores a designated transmission ratio in an updatable manner, the designated transmission ratio being a transmission ratio to which the transmission device is controlled by the electronic controller as a crank of the human-powered vehicle is rotated so that the transmission device is set to the designated transmission ratio as the human-powered vehicle is started into motion from a stopped state,
- the electronic controller being further configured to
- acquire reference information,
- determine, based on the reference information, whether to maintain the designated transmission ratio or update the designated transmission ratio to be used a next time the vehicle is started,
- execute a control to maintain or update the designated transmission ratio, and
- control the transmission device as the crank of the human-powered vehicle rotates when the human-powered vehicle is started so that the transmission ratio at which the vehicle is started is equal to the designated transmission ratio,
- the reference information excluding information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle.
