Abstract

A brake system includes a driving part driven by electric power to brake a rotary body of a human-powered vehicle and an electronic controller configured to control the driving part. The electronic controller has a plurality of control modes including a first mode that drives the driving part in accordance with a user operation and a second mode that does not drive the driving part regardless of the user operation. The electronic controller is configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

First claim

What is claimed is:

1. A brake system comprising:
a driving part driven by electric power to brake a rotary body of a human-powered vehicle; and
an electronic controller configured to control the driving part,
the electronic controller having a plurality of control modes including a first mode that drives the driving part in accordance with a user operation and a second mode that does not drive the driving part regardless of the user operation, and the electronic controller being configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

2. A brake system comprising:
a driving part driven by electric power to brake a rotary body of a human-powered vehicle; and
an electronic controller configured to control the driving part,
the electronic controller having a plurality of control modes including a first mode that drives the driving part in accordance with a user operation and a second mode that maintains the driving part in a standby state regardless of the user operation, and the electronic controller being configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

3. A brake system comprising:
a driving part driven by electric power to brake a rotary body of a human-powered vehicle; and
an electronic controller configured to control the driving part,
the electronic controller having a plurality of control modes including a first mode and a second mode that controls the driving part so that power consumption is less than the first mode, and the electronic controller being configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

4. The brake system according to claim 1 , wherein
the setting information includes first information related to vibration of the human-powered vehicle.

5. The brake system according to claim 4 , wherein
upon the electronic controller determining a still state of the human-powered vehicle exceeds a predetermined time in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

6. The brake system according to claim 4 , wherein
upon the electronic controller determining the human-powered vehicle vibrates in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

7. The brake system according to claim 1 , wherein
the setting information includes second information related to rotation of the rotary body.

8. The brake system according to claim 7 , wherein
upon the electronic controller determining a non-rotated state of the rotary body exceeds a predetermined time in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

9. The brake system according to claim 7 , wherein
upon the electronic controller determining the rotary body rotates in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

10. The brake system according to claim 1 , wherein
the setting information includes third information related to rotation of a crank to which human driving force is input.

11. The brake system according to claim 10 , wherein
upon the electronic controller determining a non-rotated state of the crank exceeds a predetermined time in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

12. The brake system according to claim 10 , wherein
upon the electronic controller determining the crank rotates in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

13. The brake system according to claim 1 , wherein
the setting information includes fourth information related to riding of the human-powered vehicle by a user.

14. The brake system according to claim 13 , wherein
the fourth information includes information related to total weight of the human-powered vehicle including weight of the user.

15. The braking system according to claim 14 , wherein
upon the electronic controller determining the total weight decreases in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

16. The braking system according to claim 14 , wherein
upon the electronic controller determining the total weight increases in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

17. The braking system according to claim 1 , wherein
the setting information includes fifth information related to an operated state of an operation unit that is manually operated to drive the driving part.

18. The braking system according to claim 17 , wherein
upon the electronic controller determining a non-operated state during which the operation unit is not operated exceeds a predetermined time in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

19. The brake system according to claim 17 , wherein
upon the electronic controller determining the operation unit is operated in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

20. The brake system according claim 1 , wherein
the setting information includes sixth information related to a locking device of the human-powered vehicle.

21. The brake system according to claim 20 , wherein
upon the electronic controller determining the locking device shifts to a lock state in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

22. The brake system according to claim 20 , wherein
upon the electronic controller determining the locking device shifts to an unlock state in the second mode, the electronic controller is configured to switch from the second mode to the first mode.

23. The brake system according to claim 1 , wherein
the setting information includes seventh information related to activation and deactivation of a switch connected to the brake system.

24. The brake system according to claim 23 , wherein
upon the electronic controller determining the switch is deactivated in the first mode, the electronic controller is configured to switch from the first mode to the second mode.

25. The brake system according to claim 23 , wherein
upon the electronic controller determining the switch is activated in the second mode, the electronic controller is configured to switch from the second mode to the first mode.
