Examples of human-powered vehicles 10 include various types of bicycles, such as mountain bikes, road bikes, city bikes, cargo bikes, hand bikes, and recumbent bikes. The number of wheels 20 that the human-powered vehicle 10 has is not limited. Examples of human-powered vehicles 10 include unicycles and vehicles with three or more wheels 20. The human-powered vehicle 10 is not limited to vehicles that can be propelled solely by human-powered driving force. The human-powered vehicle 10 also includes e-bikes that use not only human-powered driving force but also the driving force of an electric motor for propulsion. E-bikes include electrically assisted bicycles whose propulsion is assisted by an electric motor. In the following embodiments, the human-powered vehicle 10 will be described as a bicycle.

[0020] The human-powered vehicle 10 has a stem 12, a handlebar 14 connected to the stem 12, a front fork 16 connected to the stem 12, and a frame 18 connected to the front fork 16. The front fork 16 is rotatably attached to a head tube of the frame 18. The wheels 20 include a front wheel 20A and a rear wheel 20B. In this embodiment, the human-powered vehicle 10 has the wheel 20 (front wheel 20A) attached to the front fork 16.

[0021] As used herein, the following directional terms, such as "front," "rear," "forward," "backward," "left," "right," "sideways," "upward," and "downward," as well as any other similar directional terms, refer to those directions determined with reference to a rider facing the handlebars 14 in a reference position on the human-powered vehicle 10 (e.g., on the saddle or seat). As used herein, the term "rider" includes the driver of the human-powered vehicle and passengers not involved in driving the human-powered vehicle. When the human-powered vehicle is a bicycle, the rider is the rider. When the human-powered vehicle is a one-person bicycle, the rider is both the driver and the rider.

[0022] The human-powered vehicle 10 includes a brake device 30, a transmission 22, and a brake control device 40 configured to control the braking force of the brake device 30. Preferably, the transmission 22 includes an external gearbox 24. Preferably, the external gearbox 24 includes a rear derailleur 24A. The external gearbox 24 may include a front derailleur.

[0023] Preferably, the transmission 22 includes an actuator 22A. The actuator 22A is, for example, an electric motor. The transmission 22 changes the gear ratio of the human-powered vehicle 10 by being driven by the actuator 22A. The gear ratio is the ratio of the rotational speed of the wheels 20 to the rotational speed of the crank of the human-powered vehicle 10. Preferably, the gear ratio is the ratio of the rotational speed (rotational speed) of the drive wheel to the rotational speed (rotational speed) of the crank. In this embodiment, the drive wheel is the rear wheel 20B. When the transmission 22 includes a rear derailleur 24A, the gear ratio is obtained by dividing the number of teeth of the front sprocket 28B by the number of teeth of the rear sprocket 28A selected from the multiple rear sprockets 28A.

[0024] The brake device 30 includes a brake operating device 32, a brake actuator 34, and a connecting member 36. The brake device 30 applies a braking force to the wheels 20. The brake operating device 32 is connected to the brake actuator 34 to operate the brake actuator 34. The brake actuator 34 applies a braking force to the front wheels 20A. The brake device 30 may also apply a braking force to the rear wheels 20B. The connecting member 36 connects the brake operating device 32 and the brake actuator 34 via a main body 40A (described later) of the brake control device 40.

[0025] As shown in FIG. 2, the brake operating device 32 is provided on, for example, the handlebar 14. The brake actuator 34 may be a disc brake system, a rim brake system, or a roller brake system. In this embodiment, the brake device 30 is a disc brake system, and the brake actuator 34 is a disc brake caliper. The brake actuator 34 is configured to brake a disc brake rotor provided on the wheel 20 (here, the front wheel 20A). Preferably, the brake device 30 generates braking force by fluid pressure. The fluid is, for example, hydraulic oil. The interior of the connecting member 36 is filled with fluid. The connecting member 36 is a brake hose.

[0026] The brake operating device 32 operates the brake actuator 34 by the movement of fluid accompanying the operation of the brake operating device 32. The brake actuator 34 operates in accordance with the amount of operation of the brake operating device 32. The greater the amount of operation of the brake operating device 32, the greater the braking force applied by the brake actuator 34.

[0027] As shown in FIGS. 3 and 4 , the human-powered vehicle 10 includes a brake control device 40 configured to be able to control the braking force applied by the brake device 30. The brake control device 40 is configured to be able to change the relationship between the operation amount of the brake operating device 32 and the braking force. The brake control device 40 includes a main body 40A. The main body 40A is provided on the frame 18, for example. In this embodiment, the main body 40A is provided inside the frame 18. The main body 40A may also be attached to the outer surface of the frame 18. The main body 40A may also be provided on the stem 12, the handlebar 14, or the front fork 16.

[0028] As shown in FIG. 3 , the main body 40A includes a pressure control unit 46 and a drive unit 48 that drives the pressure control unit 46. The pressure control unit 46 controls the pressure of the fluid between the brake operating device 32 and the brake actuator 34. Preferably, the pressure control unit 46 includes a valve 46A provided in a fluid chamber of the main body 40A. The drive unit 48 includes an electric actuator 48A. That is, the brake control device 40 includes the electric actuator 48A. The electric actuator 48A drives the valve 46A. The electric actuator 48A is, for example, an electric motor. The electric actuator 48A may also be a solenoid. The electric actuator 48A is configured to change the fluid pressure. The drive unit 48 includes a conversion mechanism that converts the rotational motion of a rotating body of the electric actuator 48A into linear motion and transmits the linear motion to the pressure control unit 46, and a transmission mechanism (speed change mechanism) that changes the speed of the rotational motion of the rotating body of the electric actuator 48A and transmits the linear motion to the conversion mechanism.

[0029] The connecting member 36 includes a first connecting member 36A and a second connecting member 36B. The main body 40A has a first port 50 connected to the brake operating device 32 via the first connecting member 36A and a second port 52 connected to the brake actuator 34 via the second connecting member 36B. The valve 46A changes the state of fluid flow between the first port 50 and the second port 52. The electric actuator 48A of the drive unit 48 is configured to drive the valve 46A. The drive unit 48 is electrically connected to a power source that supplies power to the electric actuator 48A. Preferably, the power source is a battery (secondary battery) 54 (see FIG. 1 ) electrically connected to an assist motor that assists in propulsion of the human-powered vehicle 10. A power source dedicated to the brake control device 40 may be provided separately from the battery 54. The assist motor may be provided on the crankshaft or a hub motor provided on the wheel 20.

[0030] As shown in FIG. 4 , the control device 60 includes a control unit 62. The control unit 62 includes an arithmetic processing device that executes a predetermined control program. The arithmetic processing device includes, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The arithmetic processing devices may be provided in multiple locations that are separate from each other. The control unit 62 may include one or multiple microcomputers. The control unit 62 may be provided entirely in the main body 40A of the brake control device 40, at least a portion of the control unit 62 may be provided in the main body 40A of the brake control device 40, or the entire control unit 62 may be provided outside the brake control device 40. The control device 60 may be provided entirely in the main body 40A of the brake control device 40, at least a portion of the control unit 62 may be provided in the main body 40A of the brake control device 40, or the entire control unit 60 may be provided outside the brake control device 40.

[0031] Preferably, the control device 60 includes a storage unit 64. The storage unit 64 stores various control programs and information used in various control processes. The storage unit 64 includes, for example, a nonvolatile memory and a volatile memory. The nonvolatile memory includes, for example, at least one of a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), and a flash memory. The volatile memory includes, for example, a random access memory (RAM).

[0032] The control unit 62 controls the electric actuator 48A. Preferably, the control unit 62 controls the brake control device 40 in accordance with at least one of the state of the wheels 20 of the human-powered vehicle 10 and the operation state of the brake operation device 32 that operates the brake device 30. The state of the wheels 20 of the human-powered vehicle 10 includes, for example, at least one of the difference between the rotational speed of the front wheels 20A and the rotational speed of the rear wheels 20B, and the difference between the vehicle body speed and the vehicle speed calculated from the rotational speed of the wheels 20. The operation state of the brake operation device 32 includes, for example, at least one of the operation amount and operation speed of the brake operation device 32. Preferably, the control unit 62 drives the electric actuator 48A when at least one of the state of the wheels 20 of the human-powered vehicle 10 and the operation state of the brake operation device 32 is in a state in which slip or lock of the wheels 20 (here, the front wheels 20A) is predicted. The brake control device 40 has an anti-lock braking system (ABS) function.

[0033] Preferably, the control unit 62 controls the brake control device 40 to reduce the braking force of the brake device 30. Preferably, the control unit 62 controls the brake control device 40 to repeatedly reduce and restore the braking force of the brake device 30. When the ABS is activated, the electric actuator 48A moves the valve 46A. Accordingly, the flow path between the first port 50 and the second port 52 is blocked, and the volume of the flow path on the second port 52 side of the valve 46A in the pressure control unit 46 increases. As a result, the fluid pressure in the brake actuator 34 decreases, reducing the braking force and preventing the wheel 20 (here, the front wheel 20A) from slipping or locking. Next, the electric actuator 48A moves the valve 46A to connect the flow path between the first port 50 and the second port 52. Accordingly, if the brake operating device 32 continues to be operated, hydraulic oil is again supplied to the brake actuator 34, and the braking force is restored. Various configurations are conceivable for such a pressure reduction mechanism (ABS mechanism). The brake control device 40 can employ any pressure reducing mechanism.

[0034] The control unit 62 drives the electric actuator 48A when, for example, an operating condition is satisfied. The operating condition is satisfied when, for example, at least one of the following conditions is satisfied: when the difference between the rotation speed of the front wheels 20A and the rotation speed of the rear wheels 20B is equal to or greater than a predetermined rotation speed; when the difference between the vehicle speed and the vehicle speed calculated from the rotation speeds of the wheels 20 is equal to or greater than a predetermined speed; and when the operation amount of the brake operating device 32 per predetermined time period is equal to or greater than a predetermined operation amount.

[0035] Preferably, the human-powered vehicle 10 includes a wheel condition detection unit 56. When the operating condition is that the difference between the rotational speed of the front wheels 20A and the rotational speed of the rear wheels 20B is equal to or greater than a predetermined rotational speed, the wheel condition detection unit 56 includes a first vehicle speed sensor 56A that detects the rotational speed of the front wheels 20A and a second vehicle speed sensor 56B that detects the rotational speed of the rear wheels 20B. When the operating condition is that the difference between the vehicle speed and the vehicle speed calculated from the rotational speeds of the wheels 20 is equal to or greater than a predetermined speed, the wheel condition detection unit 56 includes one of the first vehicle speed sensor 56A and the second vehicle speed sensor 56B, and a vehicle speed sensor 56C that detects the vehicle speed of the human-powered vehicle 10. The vehicle speed sensor 56C can have any configuration. For example, the vehicle speed sensor 56C may be configured to acquire the vehicle speed using a global positioning system (GPS), or may be configured to calculate the vehicle speed by integrating acceleration. When the activation condition is that the operation amount of the brake operating device 32 per predetermined time is equal to or greater than a predetermined operation amount, the wheel state detection unit 56 includes an operation state sensor 56D that detects the operation state of the brake operating device 32.

[0036] Preferably, the human-powered vehicle 10 includes a chain condition detection unit 57. The chain condition detection unit 57 detects the driving condition of the chain 26. The chain condition detection unit 57 includes, for example, a crank rotation sensor. The crank rotation sensor detects the rotation of the crankshaft.

[0037] The control unit 62 controls the transmission 22 based on information relating to the operation of the brake control device 40. Preferably, the control unit 62 changes the gear ratio when the chain 26 of the human-powered vehicle 10 is being driven.

[0038] Preferably, the control unit 62 controls the transmission 22 based on the information regarding the operation to change the gear ratio of the human-powered vehicle 10. Preferably, the control unit 62 controls the transmission 22 based on the information regarding the operation to make the gear ratio of the human-powered vehicle 10 smaller than the current gear ratio.

[0039] Preferably, the information regarding operation includes at least one of first information indicating that an operation condition for activating the brake control device 40 is satisfied, and second information indicating operation of the brake control device 40. Preferably, the control unit 62 controls the transmission 22 to change the gear ratio of the human-powered vehicle 10 according to the duration of at least one of the first information and the second information. Here, the gear ratio of the human-powered vehicle 10 is changed in stages by the rear derailleur 24A. More specifically, the gear ratio of the human-powered vehicle 10 is changed by the rear derailleur 24A so as to become smaller in stages.

[0040] Preferably, the control unit 62 controls the transmission 22 to change the gear ratio based on the information related to the operation and the gradient D of the road surface on which the human-powered vehicle 10 is traveling. Preferably, the control unit 62 controls the transmission 22 so that the gear ratio of the human-powered vehicle 10 is different when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is equal to or greater than a predetermined gradient DX than when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is smaller than the predetermined gradient DX. For example, when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is equal to or greater than the predetermined gradient DX, the control unit 62 controls the transmission 22 so that the gear ratio becomes a first predetermined gear ratio RX. For example, when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is smaller than the predetermined gradient DX, the control unit 62 controls the transmission 22 so that the gear ratio becomes a second predetermined gear ratio RY. Preferably, the first predetermined gear ratio RX and the second predetermined gear ratio RY are smaller than the current gear ratio. Preferably, the first predetermined gear ratio RX is smaller than the second predetermined gear ratio RY. One of the first predetermined gear ratio RX and the second predetermined gear ratio RY may be the current gear ratio. If one of the first predetermined gear ratio RX and the second predetermined gear ratio RY is the current gear ratio, the control unit 62 does not change the gear ratio. Preferably, the second predetermined gear ratio RY is the current gear ratio.

[0041] The control process of the transmission 22 by the control unit 62 will be described with reference to Fig. 5. When power is supplied to the control unit 62, the control unit 62 starts the control process shown in Fig. 5 and proceeds to step S11. The control unit 62 repeats the control process shown in Fig. 5 at a predetermined cycle.

[0042] In step S11, the control unit 62 determines whether the activation conditions are satisfied or whether the brake control device 40 is activated. If the activation conditions are not satisfied and the brake control device 40 is not activated, the control unit 62 ends the processing. If the activation conditions are satisfied or the brake control device 40 is activated, the control unit 62 proceeds to step S12.

[0043] In step S12, the control unit 62 determines whether the chain 26 is driven. If the chain 26 is not driven, the control unit 62 ends the process. If the chain 26 is driven, the control unit 62 proceeds to step S13.

[0044] In step S13, the control unit 62 determines whether the gradient D is equal to or greater than a predetermined gradient DX. If the gradient D is equal to or greater than the predetermined gradient DX, the control unit 62 proceeds to step S14. In step S14, the control unit 62 controls the transmission 22 to achieve a first predetermined gear ratio RX, and then proceeds to step S16. The first predetermined gear ratio RX in step S14 is preferably a gear ratio smaller than the current gear ratio.

[0045] If the gradient D is not equal to or greater than the predetermined gradient DX in step S13, the control unit 62 proceeds to step S15. In step S15, the control unit 62 controls the transmission 22 to achieve a second predetermined gear ratio RY, and proceeds to step S16. The second predetermined gear ratio RY in step S15 is preferably a gear ratio smaller than the current gear ratio. The second predetermined gear ratio RY in step S15 is preferably a gear ratio larger than the first predetermined gear ratio RX in step S14.

[0046] In step S16, the control unit 62 determines whether the operation termination condition of the brake control device 40 is satisfied or whether the operation of the brake control device 40 has terminated. The operation termination condition is satisfied, for example, when the operation condition of the brake control device 40 is no longer satisfied. The operation termination condition is satisfied, for example, when a predetermined period of time has elapsed since the operation of the brake control device 40 began. If the operation termination condition of the brake control device 40 is not satisfied and the operation of the brake control device 40 has not terminated, the control unit 62 proceeds to step S12. If the operation termination condition of the brake control device 40 is satisfied and the operation of the brake control device 40 has terminated, the control unit 62 terminates the processing.

[0047] The period from when a positive determination is made in step S11 to when a positive determination is made in step S16 corresponds to the duration of at least one of the first information and the second information. During the duration of at least one of the first information and the second information, the control unit 62 controls the transmission 22 (here, the rear derailleur 24A) so that the gear ratio of the human-powered vehicle 10 is changed step by step toward the first predetermined gear ratio RX or the second predetermined gear ratio RY through the processing of steps S14 and S15. Preferably, the control unit 62 does not control the transmission 22 to change the gear ratio when the current gear ratio has become the first predetermined gear ratio RX in step S14. Preferably, the control unit 62 does not control the transmission 22 to change the gear ratio when the current gear ratio has become the second predetermined gear ratio RY in step S15.

[0048] Another embodiment of the control process in the control device 60 will be described with reference to Fig. 6. Preferably, the control device 60 selectively executes one of the control processes in Fig. 5 and Fig. 6 in response to at least one of a predetermined operation and a predetermined state.

[0049] In the control process shown in Fig. 6, the control unit 62 controls the transmission 22 so as not to operate the transmission 22 based on information related to operation. Preferably, the information related to operation includes first information indicating that an operation condition for operating the brake control device 40 is satisfied, and second information indicating operation of the brake control device 40. The control unit 62 controls the transmission 22 so as not to operate the transmission 22 based on at least one of the first information and the second information. Preferably, the control unit 62 controls the transmission 22 so as not to operate the transmission 22 in accordance with the duration of at least one of the first information and the second information.

[0050] When power is supplied to the control unit 62, the control unit 62 starts the control process shown in Fig. 6 and proceeds to step S21. The control unit 62 repeats the control process shown in Fig. 6 at a predetermined cycle.

[0051] In step S21, the control unit 62 determines whether the activation conditions are satisfied or whether the brake control device 40 is activated. If the activation conditions are not satisfied and the brake control device 40 is not activated, the control unit 62 ends the processing. If the activation conditions are satisfied or the brake control device 40 is activated, the control unit 62 proceeds to step S22.

[0052] In step S22, the control unit 62 controls the transmission 22 so as not to operate the transmission 22, and proceeds to step S23. In step S23, the control unit 62 determines whether or not the operation termination condition of the brake control device 40 is satisfied, or whether or not the operation of the brake control device 40 has terminated. The operation termination condition is satisfied, for example, when the operation condition of the brake control device 40 is no longer satisfied. The operation termination condition is satisfied, for example, when a predetermined period of time has elapsed since the operation of the brake control device 40 began. If the operation termination condition of the brake control device 40 is not satisfied and the operation of the brake control device 40 has not terminated, the control unit 62 proceeds to step S22. If the operation termination condition of the brake control device 40 is satisfied and the operation of the brake control device 40 has terminated, the control unit 62 terminates the processing.

[0053] The control unit 62 prohibits a change in the gear ratio from when the process of step S22 is executed until a positive determination is made in step S23. For example, during the period from when the process of step S22 is executed until a positive determination is made in step S23, the control unit 62 does not operate the transmission 22 even if the transmission operating device is operated. The period from when the process of step S22 is executed until a positive determination is made in step S23 corresponds to the duration of operation of the brake control device 40, which corresponds to at least one of the first information and the second information.

[0054] <Modification> The descriptions of the embodiments are examples of possible forms of a control device for a human-powered vehicle according to the present disclosure, and are not intended to limit the forms. A control device for a human-powered vehicle according to the present disclosure can take the form of, for example, a modified version of the embodiment shown below, or a combination of at least two mutually consistent modified versions. In the following modified versions, parts that are common to the embodiment will be assigned the same reference numerals as in the embodiment, and their description will be omitted.

[0055] In the control process shown in FIG. 5, when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is equal to or greater than a first gradient D1, the control unit 62 controls the transmission 22 so that the gear ratio of the human-powered vehicle 10 becomes a first gear ratio, and when the gradient D of the road surface on which the human-powered vehicle 10 is traveling is a second gradient D2 that is smaller than the first gradient D1, the control unit 62 may also control the transmission 22 so that the gear ratio of the human-powered vehicle 10 becomes a second gear ratio that is larger than the first gear ratio.

[0056] The transmission 22 may include an internal gearbox. In this case, the control unit 62 preferably changes the gear ratio even when the chain 26 of the human-powered vehicle 10 is not driven. Specifically, in the first embodiment, the process of step S12 in FIG. 5 is omitted.

[0057] The brake control device 40 may include a pump instead of or in addition to the electric actuator 48A.

[0058] The phrase "at least one" as used herein means "one or more" of the desired options. As an example, the phrase "at least one" as used herein means "only one option" or "both of two options" when the number of options is two. As another example, the phrase "at least one" as used herein means "only one option" or "any combination of two or more options" when the number of options is three or more. [Explanation of symbols]
