[0028] The transmission 50B is provided in the power transmission path of the human-powered vehicle 10 and is configured to change the gear ratio R. The transmission 50B has a plurality of shift stages. The gear ratios R corresponding to the respective shift stages are different from each other. The number of shift stages is, for example, in the range of 3 to 30.

[0029] The gear ratio R is the ratio of the rotational speed W of the drive wheel to the rotational speed C of the crankshaft 20. In the present embodiment, the drive wheel is the rear wheel 12R. The rotational speed W of the drive wheel and the rotational speed C of the crankshaft 20 may each be the number of rotations per unit time. The rotational speed W of the drive wheel may be replaced with the number of teeth of the first rotating body 34, and the rotational speed C of the crankshaft 20 may be replaced with the number of teeth of the second rotating body 36. The relationship among the gear ratio R, the rotational speed W of the drive wheel, and the rotational speed C of the crankshaft 20 is represented by Equation (1). Equation (1): R = W / C

[0030] For example, the transmission 50B includes at least one of an internal transmission, a front derailleur, and a rear derailleur.

The electric brake 50C may be a disc brake, a rim brake, or a roller brake. For example, the electric brake 50C includes a second electric actuator 58C. The second electric actuator 58C includes, for example, an electric motor.

[0033] For example, the electric suspension 50D includes at least one of a rear suspension and a front suspension. For example, the electric suspension 50D absorbs an impact applied to the wheel 12. The electric suspension 50D may be a hydraulic suspension or an air suspension.

[0034] The electric suspension 50D includes a first suspension portion 50G and a second suspension portion 50H that is fitted into the first suspension portion 50G and is relatively movable with respect to the first suspension portion 50G. For example, the operating state of the electric suspension 50D includes a locked state and an unlocked state.

[0035] For example, when the operating state of the electric suspension 50D is the locked state, the relative movement between the first suspension portion 50G and the second suspension portion 50H is restricted. For example, the locked state of the electric suspension 50D includes a state in which the first suspension portion 50G and the second suspension portion 50H slightly move relative to each other when a strong force is applied to the wheel 12. For example, when the operating state of the electric suspension 50D is the unlocked state, the relative movement between the first suspension portion 50G and the second suspension portion 50H is allowed. The operating state of the electric suspension 50D may include at least one of a plurality of operating states with different damping forces and a plurality of operating states with different stroke amounts, instead of or in addition to the locked state and the unlocked state.

[0036] The electric suspension 50D includes a third electric actuator 58D for operating the electric suspension 50D. The third electric actuator 58D includes an electric motor. The third electric actuator 58D may include a solenoid instead of an electric motor. For example, the third electric actuator 58D switches the operating state of the electric suspension 50D.

[0037] When the electric suspension 50D includes a rear suspension, for example, the rear suspension is provided on the frame 16 of the human-powered vehicle 10. When the electric suspension 50D includes a rear suspension, for example, the rear suspension is provided on the frame 16, between the frame main body and a swing arm that supports the rear wheel 12R. The rear suspension absorbs shocks applied to the rear wheel 12R.

[0038] When the electric suspension 50D includes a front suspension, for example, the front suspension is configured to be provided between the frame 16 and the front wheel 12F. When the electric suspension 50D includes a front suspension, for example, the front suspension is provided to the front fork 26. The front suspension absorbs shocks applied to the front wheel 12F.

[0039] For example, the electrically adjustable seatpost 50E includes a fourth electric actuator 58E. The fourth electric actuator 58E includes an electric motor. The fourth electric actuator 58E may include a solenoid instead of an electric motor. For example, the electrically adjustable seatpost 50E is provided on the seat tube. For example, the electrically adjustable seatpost 50E is configured to change the height of the saddle.

[0040] For example, the electric adjustable seat post 50E includes an electric seat post or a mechanical seat post. For example, the electric seat post has a configuration in which the seat post expands and contracts by the force of an electric actuator. For example, the mechanical seat post has a configuration in which the seat post extends by the force of at least one of a spring and air and contracts by applying manual force by controlling a valve with the force of an electric actuator. The mechanical seat post includes a hydraulic seat post or a hydraulic and pneumatic seat post.

For example, the operating device 50J is configured to output an operation signal for switching the assist mode. For example, the operating device 50J is provided on the handlebar 28. For example, the operating device 50J includes a switch 58B. The switch 58B includes an electric switch and is switched between on and off in response to the movement of an operating member provided on the operating device 50J.

[0042] For example, the human-powered vehicle 10 further includes a battery 40. The battery 40 includes one or more battery elements. The battery element includes a rechargeable battery. For example, the battery 40 is configured to supply power to the component 50. The battery 40 is communicably connected to the component 50 via an electric cable or a wireless communication device. The battery 40 can communicate with the component 50, for example, by power line communication (PLC), CAN (Controller Area Network), or UART (Universal Asynchronous Receiver / Transmitter).

[0043] The drive unit 50A includes an electric motor 60, a speed reducer 62, and an output unit 64 configured to apply a driving force to the human - powered vehicle 10. The electric motor 60 is, for example, a brushless motor. When the electric motor 60 rotates in the first motor rotation direction, the electric motor 60 outputs a motor driving force so as to apply a driving force to the human - powered vehicle 10. The electric motor 60 increases the output motor driving force as the supplied electric power increases.

[0044] The drive unit 50A has a frame attachment portion 52A for attaching to the frame 16. For example, the frame attachment portion 52A is provided on the outer peripheral portion 52J of the housing 52. The frame attachment portion 52A includes, for example, at least one of a hole and a female screw portion. For example, the housing 52 is attached to the frame 16 by a bolt engaging with at least one of the hole and the female screw portion of the frame attachment portion 52A and the frame 16.

[0045] For example, the housing 52 rotatably supports the crankshaft 20. For example, the housing 52 includes a first housing 52B, a second housing 52C, and a motor cover member 52D. The first housing 52B includes a first side surface portion 52E. The second housing 52C includes a second side surface portion 52F. The housing 52 forms an internal space SA. For example, the first housing 52B and the second housing 52C form the internal space SA. For example, the first housing 52B and the second housing 52C are attached to each other by bolts.

[0046] For example, at least a part of the crankshaft 20, at least a part of the electric motor 60, the speed reducer 62, the output unit 64, etc. are arranged in the internal space SA of the housing 52. For example, the first housing 52B functions as a case of the electric motor 60. For example, the motor cover member 52D is provided on the first housing 52B and forms a motor arrangement space together with the first housing 52B. For example, the motor cover member 52D is attached to the first housing 52B by bolts.

[0047] For example, the housing 52 includes a first hole 52G and a second hole 52H into which the crankshaft 20 is inserted. The first hole 52G and the second hole 52H communicate with the internal space SA of the housing 52 and the external space SB of the housing 52, respectively. The first hole 52G is formed in the first side surface portion 52E of the housing 52 in the axial direction X of the crankshaft 20. The second hole 52H is formed in the second side surface portion 52F of the housing 52 in the axial direction X of the crankshaft 20.

The output unit 64 is configured such that the rotational force of the crankshaft 20 is transmitted thereto. For example, the output unit 64 has a substantially cylindrical shape. For example, the output unit 64 is provided on the outer peripheral portion of the crankshaft 20 around the first rotation center axis C1.

[0049] For example, the output unit 64 is configured to be connected to the drive wheels of the power-driven vehicle 10 via a transmission member 38. For example, the output unit 64 is configured to be connected to the transmission member 38 via a second rotating body 36. For example, the output unit 64 is configured to be connected to the transmission member 38 via a sprocket, a pulley, or a bevel gear that constitutes the second rotating body 36.

[0050] For example, a power transmission member 66 is provided on the crankshaft 20. For example, the power transmission member 66 is configured to transmit the rotational force input to the crankshaft 20 to the output unit 64. For example, the power transmission member 66 has a substantially cylindrical shape. For example, the power transmission member 66 is arranged on the crankshaft 20 so as to surround the outer peripheral portion of the crankshaft 20 around the first rotation center axis C1.

[0051] For example, the drive unit 50A further includes a first one-way clutch 68. For example, the first one-way clutch 68 is configured such that when the crankshaft 20 rotates forward, the crankshaft 20 and the output portion 64 rotate integrally. The first one-way clutch 68 is configured to allow relative rotation between the crankshaft 20 and the output portion 64 when the crankshaft 20 rotates backward. For example, the first one-way clutch 68 includes a roller clutch, a sprag clutch, or a ratchet clutch. For example, the output portion 64 is connected to the power transmission member 66 via the first one-way clutch 68, and the power transmission member 66 is connected to the crankshaft 20. For example, at least a part of the first one-way clutch 68 is disposed between the inner peripheral portion of the output portion 64 and the outer peripheral portion of the power transmission member 66.

[0052] For example, the first end portion 20A of the crankshaft 20 protrudes from the first hole 52G into the external space SB of the housing 52. For example, the second end portion 20B of the crankshaft 20 protrudes from the second hole 52H into the external space SB of the housing 52. For example, a first bearing 70A is disposed in the second hole 52H. For example, the crankshaft 20 is supported by the housing 52 rotatably with respect to the housing 52 by the first bearing 70A. For example, the first bearing 70A may be a ball bearing, a roller bearing, or a sliding bearing.

[0053] For example, a second bearing 70B is disposed in the first hole 52G. For example, the output portion 64 is provided on the housing 52 rotatably with respect to the housing 52 by the second bearing 70B. For example, the second bearing 70B is provided on the outer peripheral portion of the output portion 64. The second bearing 70B may be a ball bearing, a roller bearing, or a sliding bearing.

[0054] For example, a third bearing 70C is provided between the inner peripheral portion of the power transmission member 66 and the outer peripheral portion of the crankshaft 20. For example, the power transmission member 66 rotatably supports the crankshaft 20 via the third bearing 70C. For example, a fourth bearing 70D is provided between the inner peripheral portion of the output portion 64 and the outer peripheral portion of the crankshaft 20. For example, the output portion 64 rotatably supports the crankshaft 20 via the fourth bearing 70D. For example, the third bearing 70C and the fourth bearing 70D include needle bearings or sleeves.

[0055] For example, in a direction perpendicular to the first rotation center axis C1, at least a part of the first one-way clutch 68 is arranged so as to overlap the third bearing 70C. For example, in a direction perpendicular to the first rotation center axis C1, at least a part of the second bearing 70B is arranged so as to overlap the fourth bearing 70D. For example, in a direction parallel to the first rotation center axis C1, the output portion 64 has a third end portion 64A. For example, a connecting portion for connecting the first rotating body 34 is provided on the outer peripheral portion of the third end portion 64A. For example, the connecting portion has one or a plurality of splines extending along the axial direction X of the crankshaft 20.

[0056] For example, the electric motor 60 includes a motor output shaft 60A. For example, the crankshaft 20 and the motor output shaft 60A are arranged substantially in parallel. For example, the housing 52 functions as a case of the electric motor 60. The electric motor 60 may have a case formed separately from the housing 52. When the electric motor 60 has a case, the case of the electric motor 60 may be attached to the housing 52. The case of the electric motor 60 may be attached to the outer peripheral portion 52J of the housing 52.

[0057] For example, the speed reducer 62 includes at least one speed reduction part. For example, the at least one speed reduction part includes a first speed reduction part 72, a second speed reduction part 74, and a third speed reduction part 76. The speed reducer 62 may include one, two, or four or more speed reduction parts. The first speed reduction part 72 includes a first gear 72A, a first rotating shaft 72B, and a second gear 72C. The diameter of the first gear 72A is larger than the diameter of the second gear 72C. For example, the first gear 72A is integrally formed with the output part 64. For example, the first gear 72A is provided on the outer peripheral part of the output part 64. The first gear 72A and the output part 64 may be formed separately and attached so as not to be relatively rotatable. For example, the first rotating shaft 72B has a second rotation center axis C2 different from the first rotation center axis C1. For example, the second rotation center axis C2 is substantially parallel to the first rotation center axis C1.

[0058] For example, the second gear 72C is provided on the first rotating shaft 72B. For example, the second gear 72C is formed in an annular shape and disposed on the radially outer side of the first rotating shaft 72B. For example, the second gear 72C is connected to the first gear 72A. Instead of the first gear 72A and the second gear 72C, the first speed reduction part 72 may be indirectly connected by a belt and a pulley. Instead of the first gear 72A and the second gear 72C, the first speed reduction part 72 may be indirectly connected by at least one of a sprocket and a chain. For example, the second gear 72C is supported by the first rotating shaft 72B. For example, the second gear 72C is arranged coaxially with the first rotating shaft 72B.

[0059] For example, the first rotating shaft 72B is supported by the housing 52 via a fifth bearing 70E and a sixth bearing 70F so as to be rotatable relative to the housing 52. For example, the fifth bearing 70E is provided in the first housing 52B. For example, the sixth bearing 70F is provided in the second housing 52C.

For example, the control unit 54 is configured to communicate with the communication unit 92 via at least one first electrical terminal and at least one second electrical terminal. For example, the control unit 54 is configured to communicate with the first control unit 92B via the electrical connection portion 56 and the communication unit connector 92E when the electrical connector 56A is connected to the communication unit 92. For example, the control unit 54 is configured to control the wireless communication unit 92D. For example, the control unit 54 is configured to transmit a communication signal for the first control unit 92B to control the wireless communication unit 92D to the first control unit 92B.

[0113] For example, when the second identification information does not correspond to the first identification information when the electrical connector 56A is connected to the communication unit 92, the control unit 54 is configured to control the electrical component 58.

[0114] Referring to FIG. 7, when the second identification information does not correspond to the first identification information, the process by which the control unit 54 controls the electrical component 58 will be described. For example, when power is supplied to the control unit 54, the control unit 54 starts the process and proceeds to step S11 of the flowchart shown in FIG. 7. When the flowchart in FIG. 7 ends, the control unit 54 repeats the process from step S11 at a predetermined cycle until, for example, the power supply is stopped.

[0115] In step S11, the control unit 54 determines whether the communication unit 92 is connected to the component 50. For example, when the communication unit 92 is connected to the component 50, it means that the communication unit connector 92E and the electrical connector 56A are connected. When the communication unit 92 is connected to the component 50, the control unit 54 proceeds to step S12. When the communication unit 92 is not connected to the component 50, the control unit 54 ends the process.

[0116] In step S12, the control unit 54 determines whether the first identification information corresponds to the second identification information. When the first identification information does not correspond to the second identification information, the control unit 54 proceeds to step S13. When the first identification information corresponds to the second identification information, the control unit 54 ends the process. In step S13, the control unit 54 restricts the function of the electrical component 58 and ends the process.

[0117] For example, the electrical component 58 includes the electric motor 60 of the drive unit 50A. For example, when the electrical component 58 includes the electric motor 60 and the function of the electrical component 58 is restricted, the control unit 54 controls the electric motor 60 so that the output of the electric motor 60 is suppressed. For example, when the electrical component 58 includes the electric motor 60 and the function of the electrical component 58 is restricted, the control unit 54 does not operate the electric motor 60.

Referring to FIG. 9, when the electrical component 58 includes the second electric actuator 58C of the electric brake 50C and the second identification information does not correspond to the first identification information, the process of the control unit 54 controlling the second electric actuator 58C will be described. For example, when power is supplied to the control unit 54, the control unit 54 starts the process and proceeds to step S21 of the flowchart shown in FIG. 9. When the flowchart of FIG. 9 ends, the control unit 54 repeats the process from step S21 at a predetermined cycle until, for example, the power supply is stopped. In step S21, the control unit 54 determines whether the communication unit 92 is connected to the component 50. If the communication unit 92 is connected to the component 50, the control unit 54 proceeds to step S22. If the communication unit 92 is not connected to the component 50, the control unit 54 ends the process. In step S22, the control unit 54 controls the second electric actuator 58C so that the operating state of the electric brake 50C is maintained in the brake operating state in which the electric brake 50C operates, and ends the process.

[0120] · As shown in FIG. 10, the external unit 90 may include an operation unit 96 for operating the component 50. The operation unit 96 is provided in the communication unit 92.
