Abstract

To provide a shifting control device and an electric shifting system allowing a user to comfortably ride a human-powered vehicle, a shifting control device comprising a controller configured to control a shifting device in accordance with a first operation performed on an operating device for braking a rotary body of a human-powered vehicle.

First claim

The invention claimed is:

1 . A shifting control device comprising a controller configured to control a shifting device in accordance with a first operation performed on an operating device for braking a rotary body of a human-powered vehicle, wherein
the operating device is configured to have a play operating amount before the rotary body starts to be braked in the first operation; and the shifting control device controls the shifting device so that the shifting device is actuated in the play operating amount.

2 . The shifting control device according to claim 1 , wherein
the shifting control device controls the shifting device to change a transmission ratio of the human-powered vehicle in accordance with the first operation.

3 . The shifting control device according to claim 2 , wherein
the shifting control device controls the shifting device to decrease the transmission ratio in accordance with the first operation.

4 . The shifting control device according to claim 1 , wherein
the shifting control device controls the shifting device so that an actuation aspect of the shifting device differs in accordance with operation information related to an operation state of the operating device.

5 . The shifting control device according to claim 4 , wherein
the operating device includes a lever operated by a user, and the operation information includes at least one of information related to a rotational angle of the lever, information related to a rotation speed of the lever, and information related to operating force applied to the lever.

6 . The shifting control device according to claim 1 , wherein
the shifting control device controls the shifting device so that an actuation aspect of the shifting device differs in accordance with travel information related to a travel state of the human-powered vehicle other than the first operation.

7 . The shifting control device according to claim 6 , wherein
the travel information includes first travel information related to speed of the human-powered vehicle.

8 . The shifting control device according to claim 6 , wherein
the travel information includes second travel information related to acceleration of the human-powered vehicle.

9 . The shifting control device according to claim 6 , wherein
the travel information includes third travel information related to an inclination of the human-powered vehicle.

10 . The shifting control device according to claim 9 , wherein
the third travel information includes information related to an inclination of the human-powered vehicle in a front-rear direction.

11 . The shifting control device according to claim 6 , wherein
the travel information includes fourth travel information related to force applied to the rotary body by braking.

12 . The shifting control device according to claim 6 , wherein
the travel information includes fifth travel information related to operation of a drive mechanism of the human-powered vehicle.

13 . The shifting control device according to claim 12 , wherein
the drive mechanism includes a crank, the fifth travel information includes information related to rotation speed of the crank, and the shifting control device controls the shifting device so that a difference between the rotation speed of the crank before the first operation and the rotation speed of the crank after the first operation is included in a predetermined range.

14 . The shifting control device according to claim 1 , wherein the controller is further configured to control the shifting device in:
a first control mode in which the shifting device is controlled in accordance with the first operation; and a second control mode in which the shifting device is controlled in accordance with a second operation different from the first operation.

15 . The shifting control device according to claim 14 , wherein the controller is further configured to control the shifting device in:
a third control mode in which the shifting device is programmatically controlled in accordance with travel information related to a travel state of the human-powered vehicle.

16 . The shifting control device according to claim 15 , wherein
the shifting control device controls the shifting device so that an actuation aspect of the shifting device in the first control mode differs from an actuation aspect of the shifting device in the third control mode.

17 . The shifting control device according to claim 1 , further comprising:
a storage device configured to store information related to control of the shifting device.

18 . An electric shifting system comprising:
the shifting control device according to claim 1 ; and the shifting device, configured to be electrically driven.

19 . A shifting control device comprising:
a controller configured to control a shifting device in accordance with a first operation performed on an operating device for braking a rotary body of a human-powered vehicle, wherein an operating amount of the first operation includes a first operating amount greater than an initial operating amount in an initial state of the operating device, and a second operating amount greater than the first operating amount; the controller controls the shifting device in accordance with the first operating amount so that the operating device does not brake the rotary body; and the controller controls the shifting device in accordance with the second operating amount so that the operating device brakes or does not brake the rotary body.

20 . A shifting control device comprising:
a controller configured to control a shifting device in accordance with a first operation comprising a braking operation performed on an operating device for braking a rotary body of a human-powered vehicle, wherein the controller is further configured, responsive to the first operation, to control the shifting device such that an actuation aspect of the shifting device differs in accordance with travel information related to a travel state of the human-powered vehicle other than the first operation; the travel information includes information relating to an operation of a drive mechanism of the human-powered vehicle, the drive mechanism including a crank; the travel information includes information relating to a rotation speed of the crank; and the controller is configured to control the shifting device so that a difference between the rotation speed of the crank before the first operation and the rotation speed of the crank after the first operation is included in a predetermined range.

21 . The shifting control device of claim 20 , wherein the controller is configured to control the shifting device, based on information stored in a storage device defining a control relationship between the rotation speed of the crank and an actuation aspect of the shifting control device.
