Abstract

A control system is provided for controlling an electrical component of a human-powered vehicle in accordance with a swivel state of a riding portion and a carrier. The control system includes a sensor, an electrical component and an electronic controller. The sensor is configured to output a signal corresponding to a pivot angle of a pivot portion provided between the carrier and the riding portion located between the carrier and a handle. The electronic controller is configured to control the electrical component in accordance with the signal output from the sensor.

First claim

What is claimed is:

1. A control system for a human-powered vehicle, the control system comprising:
a sensor configured to output a signal corresponding to a pivot angle of a pivot portion provided between a riding portion and a carrier, the riding portion being located between the carrier and a handle;
a drive unit including a motor configured to apply a propulsive force to the human-powered vehicle; and
an electronic controller configured to control the motor in accordance with the signal output from the sensor in a first control state where the pivot angle is a first pivot angle and in a second control state different from the first control state where the pivot angle is a second pivot angle smaller than the first pivot angle.

2. The control system according to claim 1 , wherein
the electronic controller is configured to set a maximum output value of the motor to a first output value in the first control state.

3. The control system according to claim 2 , wherein
the electronic controller is configured to set the maximum output value of the motor to a second output value in the second control state, the second output value is larger than the first output value.

4. The control system according to claim 3 , wherein
the electronic controller is configured to set a response speed of the motor into a first response speed where output of the motor increases in the first control state.

5. The control system according to claim 4 , wherein
the electronic controller is configured to set the response speed of the motor into a second response speed where the output of the motor increases in the second control state, the second response speed being higher than the first response speed.

6. The control system according to claim 1 , wherein
the electronic controller is configured to set a maximum output ratio of the motor to a human driving force input to the human-powered vehicle to a first maximum output ratio in the first control state.

7. The control system according to claim 6 , wherein
the electronic controller is configured to set the maximum output ratio of the motor to the human driving force input to the human-powered vehicle to a second maximum output ratio, the second maximum output ratio is greater than the first maximum output ratio in the second control state.

8. The control system according to claim 1 , wherein
the electronic controller is configured to stop the motor in a case where a traveling speed of the human-powered vehicle exceeds a first traveling speed in the first control state.

9. The control system according to claim 8 , wherein
the electronic controller is configured to stop the motor in a case where the traveling speed of the human-powered vehicle exceeds a second traveling speed in the second control state, the second traveling speed is greater than the first traveling speed.

10. The control system according to claim 1 , wherein
the electronic controller is configured to control an additional electrical component in accordance with the signal output from the sensor, the additional electrical component including at least one of an electric suspension, an electric seatpost, an electric rear derailleur, an electric front derailleur, an electric clutch, an electronic terminal, a display, a vibration generator, a light generator, or a sound generator.

11. A control device for a human-powered vehicle, the control device comprising:
an electronic controller configured to control a motor configured to apply a propulsive force to the human-powered vehicle in accordance with a pivot state detected by a sensor configured to output a signal corresponding to a pivot angle of a pivot portion provided between a riding portion and a carrier, the riding portion being located between the carrier and a handle, the electronic controller configured to control the motor in a first control state where the pivot angle is a first pivot angle and in a second control state different from the first control state where the pivot angle is a second pivot angle smaller than the first pivot angle.

12. The control device according to claim 11 , wherein
the electronic controller is configured to set a maximum output value of the motor to a first output value in the first control state.

13. The control device according to claim 12 , wherein
the electronic controller is configured to set the maximum output value of the motor to a second output value in the second control state, the second output value is larger than the first output value.

14. The control device according to claim 13 , wherein
the electronic controller is configured to set a response speed of the motor into a first response speed where output of the motor increases in the first control state.

15. The control device according to claim 14 , wherein
the electronic controller is configured to set the response speed of the motor into a second response speed where the output of the motor increases in the second control state, the second response speed being higher than the first response speed.

16. The control device according to claim 11 , wherein
the electronic controller is configured to set a maximum output ratio of the motor to a human driving force input to the human-powered vehicle to a first maximum output ratio in the first control state.

17. The control device according to claim 16 , wherein
the electronic controller is configured to set the maximum output ratio of the motor to the human driving force input to the human-powered vehicle to a second maximum output ratio, the second maximum output ratio is greater than the first maximum output ratio in the second control state.

18. The control device according to claim 11 , wherein
the electronic controller is configured to stop the motor in a case where a traveling speed of the human-powered vehicle exceeds a first traveling speed in the first control state.

19. The control device according to claim 18 , wherein
the electronic controller is configured to stop the motor in a case where the traveling speed of the human-powered vehicle exceeds a second traveling speed in the second control state, the second traveling speed is greater than the first traveling speed.

20. The control device according to claim 11 , wherein
the electronic controller is configured to control an additional electrical component in accordance with the signal output from the sensor, the additional electrical component including at least one of an electric suspension, an electric seatpost, an electric rear derailleur, an electric front derailleur, an electric clutch, an electronic terminal, a display, a vibration generator, a light generator, or a sound generator.
