Specifically, the hub shaft 321a is attached to the chain stay 12f (seat stay 12e). Specifically, the hub shaft 321a is attached to the rear end of the frame 12, for example, the chain stay 12f (seat stay 12e) by a fixing means, for example, a known fixing mechanism 328.

The hub shell 321b is rotatably configured around the hub shaft 321a. The rotation axis of the hub shell 321b coincides with the center axis of the hub shaft 321a. The hub shell 321b is arranged side by side with the freewheel 321c in an axial direction parallel to the central axis of the hub shaft 321a. The hub shell 321b accommodates a stator 322, a rotor 324, a power storage mechanism 325, a first cable 326, and a second cable 327. Spokes 22b are attached to the flange portion of the hub shell 321b.

The freewheel 321c is arranged side by side with the hub shell 321b in an axial direction parallel to the central axis of the hub shaft 321a. The freewheel 321c is connected to the hub shell 321b and is rotatably configured around the hub shaft 321a. The rotation axis of the freewheel 321c coincides with the center axis of the hub axis 321a. The freewheel 321c is configured to support the rear sprocket assembly 26. The freewheel 321c can transmit the rotation in the first direction to the hub shell 321b. The freewheel 321c cannot transmit rotation in the second direction, which is opposite to the first direction, to the hub shell 321b. Here, the first direction is the direction in which the rear sprocket assembly 26 rotates when the driving force is transmitted from the chain to the rear sprocket assembly 26. The freewheel 321c is formed in a substantially cylindrical shape, and a hub shaft 321a is arranged on the inner peripheral portion of the freewheel 321c.

The stator 322 is fixed to the hub shaft 321a and includes a coil. The rotor 324 is supported by the hub shell 321b. The rotor 324 can rotate relative to the hub shaft 321a. The rotor 324 includes a plurality of magnets facing the stator 322. When the rotor 324 rotates, an induced electromotive force is generated in the coil.

The power storage mechanism 325 is configured to temporarily store the power generated by the power generation unit 32. In this embodiment, the power storage mechanism 325 includes, for example, a capacitor. The power storage mechanism 325 stores the electric power generated by the coil of the stator 322. The power storage mechanism 325 supplies electric power to at least one of the component 36 and the power storage unit 30. The first cable 326 connects the coil of the stator 322 and the power storage mechanism 325. The first cable 326 transmits the electric power generated by the coil of the stator 322 to the power storage mechanism 325. The second cable 327 connects the power storage mechanism 325 and the component 36, and connects the power storage mechanism 325 and the power storage unit 30. The second cable 327 supplies the electric power stored in the electricity storage mechanism 325 to the component 36, and supplies the electric power stored in the electricity storage mechanism 325 to the electricity storage unit 30.

In this way, the power generation unit 32 generates power by the induced electromotive force generated by the rotation of the rotor 324. As described above, when the passenger applies a force to the pedal 248, the crank shaft 242 and the front sprocket 246 rotate, and the human-powered vehicle 10 operates (here, the human-powered vehicle 10 advances). The power generation unit 32 generates power by rotating the rotor 324 as the human-powered vehicle 10 travels. That is, the power generation unit 32 is a power generation mechanism that generates power according to the operation of the human-powered vehicle 10. In the present embodiment, the power generation unit 32 is a hub dynamo, but it is not limited to the hub dynamo as long as it generates power with the operation of the human-powered vehicle 10. For example, the power generation unit 32 may be a mechanism that generates power by the vibration of the suspension 36e, which will be described later, as an operation of the human-powered vehicle 10. Further, the power generation unit 32 may be a block dynamo that generates power by coming into contact with rotating bodies such as the rim 20a and the rim 22a. When the power generation unit 32 is a block dynamo, the contact state between the power generation unit 32 and the rotating body may be changed by the electric drive mechanism. Further, the power generation unit 32 such as the hub dynamo and the block dynamo may be provided on either the front wheel 20 or the rear wheel 22, or may be provided on both the front wheel 20 and the rear wheel 22. Further, the power generation unit 32 may be a mechanism that uses the electric motor of the electric auxiliary device 36d, which will be described later, as a regenerative generator. That is, the power generation unit 32 may be a mechanism that uses the electric assist device 36d as a regenerative brake.

The power generation unit 32 is configured to be able to switch between a state in which it is connected to the component 36 and a state in which it is not connected to the component 36 (a state in which it is not connected to the component 36). The state in which the power generation unit 32 is connected to the component 36 means a state in which power can be supplied from the power generation unit 32 to the component 36. The state in which the power generation unit 32 is not connected to the component 36 means a state in which power cannot be supplied from the power generation unit 32 to the component 36. In other words, the state in which the power generation unit 32 is connected to the component 36 means the state in which the power generation unit 32 can generate power, and the state in which the power generation unit 32 is not connected to the component 36 means that the power generation unit 32 does not generate power. It means a possible state.

In the present embodiment, the power generation unit 32 is detachably provided with respect to the human-powered vehicle 10. When the power generation unit 32 is attached to the human-powered vehicle 10, it is connected to the component 36, and when the power generation unit 32 is removed from the human-powered vehicle 10, it is not connected to the component 36. Will be. However, the method of switching between the state in which the power generation unit 32 is connected to the component 36 and the state in which the power generation unit 32 is not connected is not limited to the attachment / detachment to / from the human-powered vehicle 10. Further, the power generation unit 32 may not be attached to or detached from the human-powered vehicle 10. For example, the power generation unit 32 is connected to the component 36 by the operator operating the input unit 34d of the control device 34 described later in a state of being attached to the human-powered vehicle 10, that is, the power generation unit. It is possible to switch between a state in which power generation by the 32 is possible and a state in which the component 36 is not connected, that is, a state in which power generation by the power generation unit 32 is not possible. In the present embodiment, the state in which the power generation unit 32 cannot generate power is realized by the switching mechanism 330 shown in FIG. As shown in FIG. 2, the switching mechanism 330 has a cage portion 332 and an actuator 334. The cage portion 332 is a cage-shaped member provided between the stator 322 and the rotor 324. Further, the cage portion 332 is provided between the magnet of the rotor 324 and the yoke of the stator 322 facing the magnet of the rotor 324. The actuator 334 is provided on the stator 322 or the hub shaft 321a, for example, and is connected to the cage portion 332 so as to change the phase of the cage portion 332 with respect to the yoke. The actuator 334 drives the cage portion 332 to rotate the cage portion 332 in the circumferential direction of the hub shaft 321a. The cage portion 332 changes its position in the circumferential direction by rotating, and the yoke of the stator 322 is magnetically shielded from the magnet of the rotor 324, and the yoke of the stator 322 is the magnet of the rotor 324. Switch between the magnetically connected state and the state. The state in which the yoke of the stator 322 and the magnet of the rotor 324 are magnetically connected is the state in which the power generation unit 32 is connected to the component 36. That is, it is in a state where power can be generated by the power generation unit 32. Further, the state in which the yoke of the stator 322 and the magnet of the rotor 324 are magnetically cut off is a state in which the power generation unit 32 is not connected to the component 36. That is, it is impossible for the power generation unit 32 to generate power. In this way, the actuator 334 drives the cage portion 332 so that the yoke of the stator 322 and the magnet of the rotor 324 are magnetically connected, so that the power generation unit 32 is connected to the component 36. Realize. Further, by driving the cage portion 332 so that the yoke of the stator 322 and the magnet of the rotor 324 are magnetically cut off, a state in which the power generation portion 32 is not connected to the component 36 is realized.

The power storage unit 30 and the power generation unit 32 supply electric power to the component 36 under the control of the control unit 34c of the control device 34. However, as described above, the power storage unit 30 and the power generation unit 32 are switched between a state in which they are connected to the component 36 and a state in which they are not connected, and power can be supplied in the state where they are not connected to the component 36. do not have. The control device 34 according to the present embodiment recognizes whether or not the power storage unit 30 and the power generation unit 32 are connected to the component 36, so that at least one of the power storage unit 30 and the power generation unit 32 can be used. Have component 36 supply power. Hereinafter, a specific description will be given.

The control unit 34c of the control device 34 is based on the first state of whether or not the power storage unit 30 is connected to the component 36 and the second state of whether or not the power generation unit 32 is connected to the component 36. It is configured to control the power supply to the component 36. Hereinafter, the connection modes of the power storage unit and the power generation unit will be described with reference to FIGS. 4 to 6. FIG. 4 shows a storage connection mode. The power storage connection mode is a state in which the power storage unit 30 is connected to the component 36 and the power generation unit 32 is not connected to the component 36. When the control unit 34c recognizes that the power storage unit 30 is connected to the component 36 in the first state and recognizes that the power generation unit 32 is not connected to the component 36 in the second state, the power storage unit 34c recognizes that the power storage unit 30 is connected to the component 36. Recognize that it is a connection mode, and further judge. FIG. 5 shows a power generation connection mode. The power generation connection mode is a state in which the power storage unit 30 is not connected to the component 36, and the power generation unit 32 is connected to the component 36. The control unit 34c generates power when it recognizes that the power storage unit 30 is not connected to the component 36 in the first state and that the power generation unit 32 is connected to the component 36 in the second state. Recognize that it is a connection mode, and further judge. FIG. 6 shows both connection modes. In both connection modes, the power storage unit 30 is connected to the component 36, and the power generation unit 32 is connected to the component 36. When the control unit 34c recognizes that the power storage unit 30 is connected to the component 36 in the first state and recognizes that the power generation unit 32 is connected to the component 36 in the second state, both of them. Recognize, that is, judge that it is a connection mode. Since the power generation unit 32 is not connected in FIG. 4, the power generation unit 32 may actually be removed from the human-powered vehicle 10. Similarly, in FIG. 5, the power storage unit 32 may be removed. Since the 30 is not connected, the power storage unit 30 may actually be in a state of being removed from the human-powered vehicle 10.

The control unit 34c is configured to recognize that the power storage unit 30 is connected to the component when the signal from the power storage unit 30 (the first reception signal described later) is received in the first state, and the power storage unit 30 is configured. When the signal from (the first reception signal described later) is not received, the power storage unit 30 is configured to recognize that it is not connected to the component. Further, the control unit 34c recognizes that the power generation unit 32 is connected to the component when the signal from the power generation unit 32 (the second reception signal described later) is received in the second state, and the power generation unit 32 recognizes that the power generation unit 32 is connected to the component. When the signal (second received signal described later) is not received, it is recognized that the power generation unit 32 is not connected to the component. Hereinafter, the method of recognizing the first state and the second state by the control unit 34c will be described in more detail.

With reference to FIG. 7, the control unit 34c of the control device 34 determines whether or not it is in a predetermined state based on the detection result of the detection unit 34a (step S10). As described above, the predetermined state is, for example, a state in which the vibration of the human-powered vehicle 10 becomes equal to or higher than the predetermined vibration value, and is a state in which the human-powered vehicle 10 is assumed to be operating. If the control device 34 is not in the predetermined state (step S10; No), the control device 34 returns to step S10 and waits until the predetermined state is reached.

When a predetermined state is detected (step S10; Yes), the control unit 34c transmits the first signal and the second signal via the communication unit 34b (step S12). That is, the control unit 34c transmits the first signal and the second signal based on the detection result of the detection unit 34a. The control unit 34c transmits the first signal to the power storage unit 30 and the second signal to the power generation unit 32 via the communication unit 34b. In other words, the control unit 34c transmits the first signal with the power storage unit 30 as the transmission destination, and transmits the second signal with the power generation unit 32 as the transmission destination. The first signal and the second signal are pins. Therefore, the control unit 34c transmits a first signal to the power storage unit 30 to confirm whether it can communicate with the power storage unit 30, and confirms to the power generation unit 32 whether it can communicate with the power generation unit 32. It can be said that the second signal for the purpose is transmitted.

When the power storage unit 30 is connected to the component 36, the power storage unit 30 is also connected to the control device 34, so that the power storage unit 30 can communicate with the control device 34 by a communication unit (not shown). .. Further, when the power storage unit 30 is connected to the component 36, the power storage unit 30 can supply power to the component 36, so that the power storage amount remains and the communication unit can be activated to communicate with the control device 34. It becomes. Therefore, when connected to the component 36, the power storage unit 30 receives the first signal from the control device 34 via the communication unit. The power storage unit 30 recognizes that the first signal has been received by, for example, a CPU (not shown), and when it recognizes that the first signal has been received, the power storage unit 30 transmits the first reception signal to the control device 34 via the communication unit. Send. The control device 34 receives the first reception signal transmitted by the power storage unit 30. The first received signal is a signal indicating that the first signal has been received, in other words, the storage unit 30 can communicate with the control device 34, and the storage unit 30 is connected to the component 36. It can be said that it is a signal. On the other hand, when the power storage unit 30 is not connected to the component 36, the power storage unit 30 is not connected to the control device 34 (is not connected to the control device 34), and therefore communicates with the control unit 34c. It will be impossible. Therefore, when the power storage unit 30 is not connected to the component 36, the power storage unit 30 does not receive the first signal from the control device 34. In this case, the power storage unit 30 does not transmit the first reception signal to the control device 34, and the control device 34 does not receive the first reception signal.

The control unit 34c of the control device 34 determines whether or not the first reception signal from the power storage unit 30 has been received via the communication unit 34b (step S14). When the control unit 34c receives the first reception signal from the power storage unit 30 (step S14; Yes), the control unit 34c recognizes that the power storage unit 30 is connected to the component 36 in the first state (step S16). On the other hand, when the control unit 34c does not receive the first reception signal (step S14; No), the control unit 34c recognizes that the power storage unit 30 is not connected to the component 36 in the first state (step S18).

When the power generation unit 32 is connected to the component 36, the power generation unit 34 is also connected to the control device 34, so that the power generation unit 34 can communicate with the control device 34 by a communication unit (not shown). .. Further, when the power generation unit 32 is connected to the component 36, the power generation unit 34 can supply electric power to the component 36. Therefore, for example, the power storage amount remains in the power storage mechanism 325, and the communication unit is activated and controlled. It becomes possible to communicate with the device 34. Therefore, when connected to the component 36, the power generation unit 32 receives the second signal from the control device 34 via the communication unit. The power generation unit 32 recognizes that the second signal has been received by, for example, a CPU (not shown), and when it recognizes that the second signal has been received, the power generation unit 32 transmits the second reception signal to the control device 34 via the communication unit. Send. The second received signal is a signal indicating that the second signal has been received, in other words, indicating that the power generation unit 32 can communicate with the control device 34 and that the power generation unit 32 is connected to the component 36. It can be said that it is a signal. On the other hand, when the power generation unit 32 is not connected to the component 36, the power generation unit 34 is not connected to the control device 34 (is not connected to the control device 34), and therefore communicates with the control unit 34c. It will be impossible. Therefore, when the power generation unit 32 is not connected to the component 36, the power generation unit 34 does not receive the second signal from the control device 34. In this case, the power generation unit 32 does not transmit the second received signal to the control device 34, and the control device 34 does not receive the second received signal.

After recognizing in step S16 or step S18 whether or not the power storage unit 30 is connected to the component 36, the control unit 34c of the control device 34 transmits the second reception signal from the power generation unit 32 via the communication unit 34b. It is determined whether or not it has been received (step S20). When the control unit 34c receives the second reception signal from the power generation unit 32 (step S20; Yes), the control unit 34c recognizes that the power generation unit 32 is connected to the component 36 in the second state (step S22). On the other hand, when the control unit 34c does not receive the second reception signal (step S20; No), the control unit 34c recognizes that the power generation unit 32 is not connected to the component 36 in the second state (step S24). In this way, when it is recognized in step S16 or step S18 whether or not the power generation unit 32 is connected to the component 36, the recognition of the first state and the second state, that is, the power storage unit 30 and the power generation unit 32 are components. The process of confirming whether or not the device is connected to 36 ends. In the description of FIG. 7, after the confirmation of the first state in steps S14 to S18, the confirmation of the second state in steps S20 to S24 was performed, but the confirmation of the first state and the second state was performed. The order of is arbitrary, and the second state may be confirmed first, or the first state and the second state may be confirmed at the same time.

Further, as described above, the control unit 34c transmits the first signal and the second signal by using the detection of the predetermined state as a trigger. In this case, the control unit 34c may transmit the first signal and the second signal along with the detection of the detection unit 34a at predetermined intervals, and confirm the first state and the second state. By monitoring whether or not the state is the first state and the second state in this way, the current connection state can be more preferably grasped. Further, the control unit 34c may transmit the first signal and the second signal without detecting the detection unit 34a. In this case, for example, the control unit 34c may transmit the first signal and the second signal at predetermined intervals regardless of whether or not it is in a predetermined state. Further, the control device 34 does not have to transmit the first signal and the second signal again after transmitting the first signal and the second signal once.

The control unit 34c confirms the first state and the second state as described above. When the control unit 34c recognizes that the power storage unit 30 is connected in the first state and the power generation unit 32 is not connected in the second state, it recognizes that it is the power storage connection mode shown in FIG. 4, and the power storage connection mode. Performs control of the power supply in. Further, when the control unit 34c recognizes that the power storage unit 30 is not connected in the first state and the power generation unit 32 is connected in the second state, it recognizes that the power generation connection mode is shown in FIG. Then, control the power supply in the power generation connection mode. Further, when the control unit 34c recognizes that the power storage unit 30 is connected in the first state and the power generation unit 32 is connected in the second state, that is, the power storage unit 30 is connected in the first state and the second state. When it recognizes that the power generation unit 32 is connected to the component 36, it recognizes that it is in both connection modes shown in FIG. 6, and controls the power supply in both connection modes. Hereinafter, the power supply control in each mode will be described.

First, the power supply control in the storage connection mode shown in FIG. 4 will be described. When the control unit 34c recognizes that it is in the power storage connection mode, the control unit 34c controls the power storage unit 30 so that the power storage unit 30 supplies the power W1 to the component 36 as shown in FIG. In other words, the control unit 34c controls the power storage unit 30 so as to supply the power required by the component 36 when the control unit 34c recognizes that it is in the power storage connection mode. That is, in the power storage connection mode, the power generation unit 32 does not generate power, and the power generation unit 32 does not supply power to the component 36. For example, the control unit 34c transmits a signal instructing the communication unit of the power storage unit 30 to supply the power required by the component 36 via the communication unit 34b. Upon receiving the signal, the power storage unit 30 supplies the electric power W1 to the component 36 as needed of the component 36. The component 36 is driven by the electric power W1 from the electricity storage unit 30 in the electricity storage connection mode.

Next, the power supply control in the power generation connection mode shown in FIG. 5 will be described. When the control unit 34c recognizes that it is in the power generation connection mode, the control unit 34c controls the power generation unit 32 so that the power generation unit 32 supplies the power W2 to the component 36 as shown in FIG. In other words, when the control unit 34c recognizes that it is in the power generation connection mode, the control unit 34 controls the power generation unit 32 so as to supply the power required by the component 36. That is, in the power storage connection mode, power is not supplied from the power storage unit 30 to the component 36. For example, the control unit 34c transmits a signal instructing the communication unit of the power generation unit 32 to supply the power required by the component 36 via the communication unit 34b. Upon receiving the signal, the power generation unit 32 supplies the electric power W2 to the component 36 as needed of the component 36. The component 36 is driven by the electric power W1 from the power generation unit 32 in the power generation connection mode.

Next, the power supply control in both connection modes shown in FIG. 6 will be described. When the control unit 34c recognizes that it is in both connection modes, as shown in FIG. 6, the power storage unit 30 and the power generation unit 32 are supplied with power from at least one of the power storage unit 30 and the power generation unit 32 to the component 36. Control. More specifically, the control unit 34c causes the component 36 to supply electric power from the power storage unit 30 when the power storage amount of the power storage unit 30 is equal to or higher than the first predetermined value in both connection modes. Specifically, when the control unit 34c recognizes that it is in both connection modes, it acquires information on the amount of electricity stored from the electricity storage unit 30. When the control unit 34c recognizes from the information on the amount of electricity stored that the amount of electricity stored in the electricity storage unit 30 is equal to or greater than the first predetermined value, the control unit 34c controls the electricity storage unit 30 so as to supply the power required by the component 36. .. For example, the control unit 34c transmits a signal instructing the communication unit of the power storage unit 30 to supply the power required by the component 36 via the communication unit 34b. Upon receiving the signal, the power storage unit 30 supplies the electric power W2 to the component 36 as needed of the component 36. The first predetermined value here may be an arbitrary value set in advance, but for example, it is preferably a value of about 20% or more and 70% or less with respect to the maximum storage amount of the power storage unit 30.

Then, it is preferable that the control unit 34c stops the power generation from the power generation unit 32 when the storage amount of the power storage unit 30 is equal to or more than the first predetermined value in both connection modes. That is, when the power storage unit 30 has a margin, the control unit 34c stops the power generation from the power generation unit 32 to reduce the load on the passenger required for the power generation of the power generation unit 32, and the power storage unit 34c reduces the load on the passenger. Priority is given to the power supply from 30. To stop the power generation from the power generation unit 32, as described above, the position of the cage portion 332 is adjusted by the switching mechanism 330, and the stator 322 and the rotor 324 of the power generation unit 32 are magnetically cut off. It is realized by making it absent. When the power generation from the power generation unit 32 is stopped, the load for power generation becomes unnecessary, and the operating load of the passenger is reduced. However, the control unit 34c may generate power from the power generation unit 32 as necessary even when the storage amount of the power storage unit 30 is equal to or greater than the first predetermined value in both connection modes. In this case, the control unit 34c may supply the electric power from the power generation unit 32 to the component 36 in addition to the electric power from the power storage unit 30. Further, the control unit 34c may charge the power storage unit 30 with the power from the power generation unit 32 by supplying the power from the power generation unit 32 to the power storage unit 30.

Further, the control unit 34c causes the component 36 to supply electric power from the power generation unit 32 when the amount of electricity stored in the power storage unit 30 is less than the second predetermined value in both connection modes. When the control unit 34c recognizes that the electricity storage amount of the electricity storage unit 30 is less than the second predetermined value from the information of the electricity storage amount, the control unit 34c controls the power generation unit 32 so as to supply the electric power required by the component 36. .. For example, the control unit 34c transmits a signal instructing the communication unit of the power generation unit 32 to supply the power required by the component 36 via the communication unit 34b. Upon receiving the signal, the power generation unit 32 supplies the electric power W2 to the component 36 as needed of the component 36. The second predetermined value here is the same value as the first predetermined value in the present embodiment, but may be a value different from the first predetermined value, and may be an arbitrary value set in advance.

Then, the control unit 34c does not supply power from the power storage unit 30 to the component 36 when the power storage amount of the power storage unit 30 is less than the second predetermined value in both connection modes. That is, when the power storage amount of the power storage unit 30 becomes insufficient, the control unit 34c stops the power supply from the power storage unit 30 and gives priority to the power supply from the power generation unit 32. Further, the control unit 34c may charge the power storage unit 30 with the power W3 from the power generation unit 32 when the storage amount of the power storage unit 30 is less than the second predetermined value in both connection modes.
