[0040] The second communication unit 31 has the same configuration as the first communication unit 24 of the component 21. For example, a wireless signal related to the remaining battery charge of the first battery 19a is input to the second communication unit 31 from the first communication unit 24. The second communication unit 31 can output a wireless signal related to the remaining battery charge of the second battery 19b and a wireless signal related to the operating state of the operating device 26 to the first communication unit 24.

[0041] The second control device 32 includes a second storage unit 32a and a second control unit 32b. The second storage unit 32a stores various control programs and information used in various control processes. The second storage unit 32a includes, for example, a non-volatile memory and a volatile memory.

[0042] The second control unit 32b is configured to execute control related to the operation device 26. The second control unit 32b includes an arithmetic processing unit that executes a predetermined control program. The arithmetic processing unit includes, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The second control unit 32b may include one or more microcomputers.

[0043] At least one of the first control unit 25b and the second control unit 32b controls the component 21 depending on the remaining battery power and the operation state of the operating device 26. In this embodiment, the second control unit 32b controls the component 21. An example of the control executed by the second control unit 32b will be described. FIG. 4 is used to describe the example of the control executed by the second control unit 32b. The second control unit 32b starts a first control flow according to the flowchart shown in FIG. 4 when a predetermined condition is satisfied. For example, the second control unit 32b starts the first control flow when the operation state detection unit 30b detects a predetermined operation state.

[0044] In step S1, the second control unit 32b acquires the remaining battery charge and the operation state of the operating device 26. The second control unit 32b acquires the remaining battery charge of at least one of the first battery 19a and the second battery 19b. In this embodiment, the second control unit 32b acquires the remaining battery charge of the first battery 19a and the second battery 19b. The second control unit 32b requests information regarding the remaining battery charge of the first battery 19a from the first control unit 25b via the first communication unit 24 and the second communication unit 31. The first control unit 25b inputs a wireless signal regarding the remaining battery charge to the second control unit 32b via the first communication unit 24 and the second communication unit 31. The second control unit 32b acquires the remaining battery charge of the first battery 19a based on the wireless signal from the first control unit 25b. The second control unit 32b acquires the remaining battery charge of the second battery 19b based on a signal from the second remaining charge detection unit 30a. Based on the signal from the operation state detection unit 30b, the second control unit 32b acquires the operation state of the operation device 26. After performing the process of step S1, the second control unit 32b proceeds to step S2.

[0045] In step S2, the second control unit 32b controls the component 21 according to the remaining battery charge acquired in step S1 and the operation state of the operation device 26. The second control unit 32b changes the operation state of the component 21 corresponding to the operation state of the operation device 26 according to the remaining battery charge. For example, when the remaining battery charge is equal to or greater than a preset threshold, the second control unit 32b activates the component 21 according to the operation state. When the remaining battery charge is less than a preset threshold, the second control unit 32b does not activate the component 21 regardless of the operation state. After performing the process of step S2, the second control unit 32b ends the first control flow.

[0046] By having the second control unit 32b execute the first control flow, the user can check the remaining battery charge based on the operating state of the component 21 when operating the operation device 26. The user can easily check the remaining battery charge without looking at the display. The user can prevent problems caused by the depletion of the battery 19 by charging or replacing the battery 19 according to the checked remaining battery charge. For example, the user can charge or replace the battery 19 before the battery runs out and it becomes impossible to change the gear ratio of the human-powered vehicle 10.

[0047] The device that executes the first control flow is not limited to the second control unit 32b. Another control unit may execute the first control flow. For example, the first control unit 25b may execute the first control flow. When the first control unit 25b executes the first control flow, in step S1, a wireless signal related to the operation state of the operating device 26 and a wireless signal related to the remaining battery power of the second battery 19b are output from the second communication unit 31 to the first communication unit 24. The first control unit 25b acquires the operation state and the remaining battery power of the second battery 19b based on the wireless signals output to the first communication unit 24.

[0048] (Second embodiment) A control system 20 according to a second embodiment will be described. The control system 20 according to the second embodiment will be described with reference to Figs. 3 to 5. The same components as those in the first embodiment will be assigned the same reference numerals as those in the first embodiment, and redundant description will be omitted.

[0049] In this embodiment, the operating state includes a first operating state. The first operating state includes at least one of an operating state related to an upshift of the gearshift operating device 14b and an operating state related to a downshift. The operating state related to an upshift includes, for example, a state in which one of the two operating units 29 shown in FIG. 3 is swung into an operating position for less than a predetermined time. The operating state related to a downshift includes, for example, a state in which the other of the two operating units 29 shown in FIG. 3 is swung into an operating position for less than a predetermined time.

[0050] The second control unit 32b activates the component 21 when the remaining battery charge is equal to or greater than the first threshold and the operation state is the first operation state, and does not activate the component 21 when the remaining battery charge is less than the first threshold and the operation state is the first operation state. FIG. 5 is used to explain an example of control executed by the second control unit 32b. The second control unit 32b starts a second control flow according to the flowchart shown in FIG. 5 when a predetermined condition is satisfied. The condition for starting the second control flow is the same as in the first embodiment.

[0051] In step S11, the second control unit 32b performs the same process as in step S1 shown in Fig. 4 to acquire the remaining battery charge and the operation state of the operation device 26. After performing the process of step S11, the second control unit 32b proceeds to step S12.

[0052] In step S12, the second control unit 32b acquires a predetermined first threshold by reading information stored in the second storage unit 32a. If the remaining battery charge of at least one of the first battery 19a and the second battery 19b acquired in step S11 is less than the first threshold and the operation state of the operation device 26 acquired in step S11 is the first operation state, the second control unit 32b proceeds to step S13. If the remaining battery charge of the first battery 19a and the second battery 19b acquired in step S11 is equal to or greater than the first threshold or if the operation state acquired in step S11 is not the first operation state, the second control unit 32b proceeds to step S14.

[0053] The second control unit 32b may proceed to step S13 if the remaining battery charge of the first battery 19a acquired in step S11 is less than the first threshold and the operation state of the operation device 26 acquired in step S11 is the first operation state, without comparing the remaining battery charge of the second battery 19b with the first threshold in step S12. The second control unit 32b may proceed to step S13 if the remaining battery charge of the second battery 19b acquired in step S11 is less than the first threshold and the operation state acquired in step S11 is the first operation state, without comparing the remaining battery charge of the first battery 19a with the first threshold in step S12. The second control unit 32b may proceed to step S13 only if the remaining battery charges of the first battery 19a and the second battery 19b acquired in step S11 are each less than the first threshold when the operation state acquired in step S11 is the first operation state.

[0054] In step S13, the second control unit 32b does not operate the component 21. For example, the second control unit 32b does not cause the second communication unit 31 to output a wireless signal. After performing the process of step S12, the second control unit 32b ends the second control flow.

[0055] In step S14, if the remaining battery power of the first battery 19a and the second battery 19b acquired in step S11 is equal to or greater than the first threshold and the operation state of the operation device 26 acquired in step S11 is the first operation state, the second control unit 32b proceeds to step S15. If the remaining battery power of at least one of the first battery 19a and the second battery 19b acquired in step S11 is less than the first threshold or the operation state acquired in step S11 is not the first operation state, the second control unit 32b proceeds to step S13.

[0056] In step S14, the second control unit 32b may proceed to step S15 if the remaining battery charge of the first battery 19a is equal to or greater than the first threshold and the operation state of the operation device 26 is the first operation state, without comparing the remaining battery charge of the second battery 19b with the first threshold. In step S14, the second control unit 32b may proceed to step S15 if the remaining battery charge of the second battery 19b is equal to or greater than the first threshold and the operation state of the operation device 26 is the first operation state, without comparing the remaining battery charge of the first battery 19a with the first threshold.

[0057] In step S15, the second control unit 32b operates the component 21. For example, the second control unit 32b outputs a wireless signal corresponding to the first operation state to the second communication unit 31. The wireless signal from the second communication unit 31 is input to the first communication unit 24. The component 21 is operated in response to the wireless signal input to the first communication unit 24. For example, when the operation device 26 is operated so that the operation state of the operation device 26 becomes an operation state related to downshifting, the component 21 is operated to decrease the gear ratio of the human-powered vehicle 10. After performing the process of step S15, the second control unit 32b ends the second control flow.

[0058] By having the second control unit 32b execute the second control flow, the user can confirm that the remaining battery charge is equal to or greater than the first threshold, based on the fact that the component 21 operates when the operation device 26 is in the first operation state. The user can confirm that the remaining battery charge is less than the first threshold, based on the fact that the component 21 does not operate when the operation device 26 is in the first operation state. The second control flow may be executed by the first control unit 25b, instead of the second control unit 32b.

[0059] (Third embodiment) A control system 20 according to a third embodiment will be described. The control system 20 according to the third embodiment will be described with reference to Figs. 3 to 6. The same reference numerals as those in the first and second embodiments are used for the components common to the first and second embodiments, and redundant description will be omitted.

[0060] In this embodiment, the first operating state includes an operating state related to upshifting and an operating state related to downshifting of the gearshift operating device 14b. The operating state includes a second operating state different from the first operating state. The second operating state includes a state in which at least one of the two levers shown in FIG. 3 is swung to the operating position for a predetermined time or longer, and a state in which at least one of the two levers is swung to the operating position multiple times within the predetermined time. The second control unit 32b activates the component 21 when the remaining battery charge is less than the first threshold and the operating state is the second operating state.

[0061] An example of control executed by the second control unit 32b will be described. Fig. 6 is used to explain the example of control executed by the second control unit 32b. The second control unit 32b starts a third control flow according to the flowchart shown in Fig. 6 when a predetermined condition is satisfied. The condition for starting the third control flow is the same as in the first embodiment.

[0062] In step S21, the second control unit 32b performs the same process as in step S1 shown in Fig. 4 to acquire the remaining battery charge and the operation state of the operating device 26. After performing the process of step S21, the second control unit 32b proceeds to step S22.

[0063] 5, in step S22, if the remaining battery charge acquired in step S21 is less than the first threshold and the operation state of the operation device 26 acquired in step S21 is the first operation state, the second control unit 32b proceeds to step S23. If the remaining battery charge acquired in step S21 is equal to or greater than the first threshold or if the operation state acquired in step S21 is not the first operation state, the second control unit 32b proceeds to step S24.

[0064] In step S23, the second control unit 32b does not operate the component 21. After performing the process of step S23, the second control unit 32b ends the third control flow.

[0065] In step S24, if the remaining battery power of the first battery 19a and the second battery 19b acquired in step S21 is equal to or greater than the first threshold and the operation state of the operation device 26 acquired in step S21 is the first operation state, the second control unit 32b proceeds to step S25. If the remaining battery power of at least one of the first battery 19a and the second battery 19b acquired in step S21 is less than the first threshold or the operation state acquired in step S21 is not the first operation state, the second control unit 32b proceeds to step S26.

[0066] In step S24, the second control unit 32b may proceed to step S25 if the remaining battery charge of the first battery 19a is equal to or greater than the first threshold and the operation state of the operation device 26 is the first operation state, without comparing the remaining battery charge of the second battery 19b with the first threshold.In step S24, the second control unit 32b may proceed to step S25 if the remaining battery charge of the second battery 19b is equal to or greater than the first threshold and the operation state of the operation device 26 is the first operation state, without comparing the remaining battery charge of the first battery 19a with the first threshold.

[0067] In step S25, the second control unit 32b operates the component 21. For example, the second control unit 32b causes the second communication unit 31 to output a wireless signal corresponding to the first operation state. After performing the process of step S25, the second control unit 32b ends the third control flow.

[0068] In step S26, if the remaining battery charge of at least one of the first battery 19a and the second battery 19b acquired in step S21 is less than the first threshold and the operation state of the operation device 26 acquired in step S21 is the second operation state, the second control unit 32b proceeds to step S25. If the remaining battery charge of the first battery 19a and the second battery 19b acquired in step S21 is equal to or greater than the first threshold or the operation state acquired in step S21 is not the second operation state, the second control unit 32b proceeds to step S27.

[0069] In step S26, the second control unit 32b may proceed to step S25 if the remaining battery charge of the first battery 19a is less than the first threshold and the operation state of the operation device 26 is the second operation state, without comparing the remaining battery charge of the second battery 19b with the first threshold. In step S26, the second control unit 32b may proceed to step S25 if the remaining battery charge of the second battery 19b is less than the first threshold and the operation state of the operation device 26 is the second operation state, without comparing the remaining battery charge of the first battery 19a with the first threshold. When the operation state of the operation device 26 is the second operation state, the second control unit 32b may proceed to step S25 only if the remaining battery charges of the first battery 19a and the second battery 19b are each less than the first threshold.

[0070] In step S27, the second control unit 32b does not operate the component 21. After performing the process of step S27, the second control unit 32b ends the third control flow.

[0071] By having the second control unit 32b execute the third control flow, the user can activate the component 21 by changing the operation state of the operation device 26 to the second operation state when the remaining battery charge is less than the first threshold. For example, when the remaining battery charge is less than the first threshold, the user can change the gear ratio of the human-powered vehicle 10 by continuously operating the lever of the gear change operation device 14b. The third control flow may be executed by the first control unit 25b instead of the second control unit 32b.

[0072] (Fourth embodiment) A control system 20 according to a fourth embodiment will be described. The control system 20 according to the fourth embodiment will be described using Fig. 4, Fig. 6, and Fig. 7. The same reference numerals as those in the first to third embodiments will be used for the components common to the first to third embodiments, and redundant description will be omitted.

[0073] In this embodiment, the component 21 includes the electric transmission 18. The operating device 26 includes a shift operating device 14b configured to operate the electric transmission 18. The operating states include a first operating state and a third operating state.

[0074] The first operating state includes one of an operating state related to upshifting of the gearshift operating device 14b and an operating state related to downshifting. The third operating state is different from the first operating state. The third operating state includes the other of an operating state related to upshifting of the gearshift operating device 14b and an operating state related to downshifting.

[0075] When the operation state is the third operation state, the second control unit 32b activates the component 21 regardless of the remaining battery charge. An example of the control executed by the second control unit 32b will be described below. FIG. 7 is used to describe the example of the control executed by the second control unit 32b. The second control unit 32b starts a fourth control flow according to the flowchart shown in FIG. 7 when a predetermined condition is satisfied. The condition for starting the fourth control flow is the same as in the first embodiment.

[0076] Steps S31 to S34 are the same as steps S21 to S24 shown in Fig. 6. In step S35, the second control unit 32b activates the component 21. When moving from step S34 to step S35, the second control unit 32b causes the second communication unit 31 to output a wireless signal corresponding to the first operation state. When moving from step S36 to step S35, the second control unit 32b causes the second communication unit 31 to output a wireless signal corresponding to the third operation state. After performing the process of step S35, the second control unit 32b ends the fourth control flow.

[0077] In step S36, if the operation state of the operation device 26 acquired in step S31 is the third operation state, the second control unit 32b proceeds to step S35. If the operation state acquired in step S31 is not the third operation state, the second control unit 32b proceeds to step S37.

[0078] In step S37, the second control unit 32b does not operate the component 21. After performing the process of step S37, the second control unit 32b ends the fourth control flow.

[0079] By having the second control unit 32b execute the fourth control flow, the user can easily check the remaining battery charge based on whether the component 21 is operable when the operation state of the operation device 26 is set to the first operation state. The user can operate the component 21 according to the third operation state regardless of the remaining battery charge. The fourth control flow may be executed by the first control unit 25b instead of the second control unit 32b.

[0080] Tables 1 and 2 show the relationship between the operation states for upshifting, the operation states for downshifting, and whether or not gear shifting is possible in this embodiment.

[0081] [Table 1] In Table 1, the first operating state includes an operating state related to a downshift. The third operating state includes an operating state related to an upshift. The user can operate the component 21 to increase the gear ratio of the human-powered vehicle 10 by operating the gear change operating device 14b, regardless of the remaining battery charge.

[0082] [Table 2] In Table 2, the first operating state includes an operating state related to an upshift. The third operating state includes an operating state related to a downshift. The user can operate the component 21 to decrease the gear ratio of the human-powered vehicle 10 by operating the gear change operating device 14b, regardless of the remaining battery charge.

[0083] In the fourth control flow, when the remaining battery charge is less than the first threshold value and the operation state of the operation device 26 is the second operation state, the second control unit 32b may operate the component 21 by causing the second communication unit 31 to output a wireless signal corresponding to the first operation state.

[0084] (Fifth embodiment) A control system 40 according to a fifth embodiment will be described. The control system 40 according to the fifth embodiment will be described with reference to Figs. 4 to 8. The same reference numerals as those in the first to fourth embodiments will be used to designate components common to the first to fourth embodiments, and redundant description will be omitted.

The drive unit 41c is configured to provide propulsive force to the human-powered vehicle 10 in response to human-powered driving force input to the human-powered vehicle 10. The drive unit 41c is disposed, for example, near the bottom bracket of the human-powered vehicle 10. The drive unit 41c may be disposed near the front wheel 16 and the rear wheel 17. The drive unit 41c includes an electric motor. The electric motor is provided in a power transmission path of the human-powered driving force from the pedals 11c to the rear wheel 17, or to transmit rotation to the front wheel 16. In addition to the electric motor, the drive unit 41c may also include a reducer that connects the electric motor to the crank 11.

[0089] The operation device 42 includes at least one of a gear shift operation device 14b, a suspension operation device 42a, a seat post operation device 42b, and an assist operation device 42c. The suspension operation device 42a is configured to allow the user to perform an operation to change the operating parameters of the electric suspension 41a. The seat post operation device 42b is configured to allow the user to perform an operation to change the height of the seat 13. The assist operation device 42c is configured to allow the user to perform an operation to switch the assist mode of the drive unit 41c.

[0090] At least one of the first control unit 25b of the component 41 and the second control unit 32b of the operation device 42 executes one of the control flows from the first control flow shown in Fig. 4 to the fourth control flow shown in Fig. 7. For example, the second control unit 32b of the operation device 42 executes the first control flow.

[0091] By executing the control flow, at least one of the electric transmission 18, the electric suspension 41a, the electric seat post 41b, and the drive unit 41c is controlled according to the remaining battery charge and the operating state of the operating device 26. For example, if the remaining battery charge of the first battery 19a is less than a first threshold, the electric suspension 41a is activated by operating the suspension operating device 42a for a predetermined period of time or longer. The user can easily check the remaining battery charge of the battery 19 that supplies power to the electric suspension 41a.

The control system 50 according to the sixth embodiment will be described using Fig. 2, Fig. 9, and Fig. 10. The same reference numerals as those in the first to fifth embodiments will be used to designate components common to the first to fifth embodiments, and redundant description will be omitted.

The control system 50 shown in FIG. 9 includes the component 60 and the operating device 70.

[0096] The component 60 includes a first component 61 and a second component 63 that is different from the first component 61. The first component 61 is mounted on the human-powered vehicle 10.

[0105] The fourth control device 78 includes a fourth storage unit 77a and a fourth control unit 77b. The fourth storage unit 77a is configured similarly to the first storage unit 62a. The fourth control unit 77b is configured to execute control related to the second operating device 75. The fourth control unit 77b includes an arithmetic processing unit, similar to the first control unit 62b.

[0106] In this embodiment, the first operating device 71 of the operating device 70 outputs an operating signal corresponding to the operating state detected by the first detecting unit 73 to the first component 61. The second operating device 75 outputs an operating signal corresponding to the operating state detected by the second detecting unit 77 to the first component 61 and the second component 63.

[0107] The second control device 64 activates the second component 63 in response to an operation signal from the second operating device 75. For example, the second control device 64 changes the assist mode. The first control device 62 controls the first component 61 in response to the remaining battery charge of the first battery 49a and the operation signal from the second operating device 75. The first control unit 62b of the first control device 62 does not activate the first component 61 in response to the operation state of the second operating device 75 when the remaining battery charge of the first battery 49a is equal to or greater than a first threshold, and activates the first component 61 in response to the operation state of the second operating device 75 when the remaining battery charge of the first battery 49a is less than the first threshold.

[0108] An example of control executed by the first control unit 62b will be described below. Fig. 10 is used to describe the example of control executed by the first control unit 62b. The first control unit 62b starts a fifth control flow according to the flowchart shown in Fig. 10 when a predetermined condition is satisfied. For example, the first control unit 62b starts a fourth control flow when an operation signal is output from the second operation device 75 to the first component 61.

[0109] In step S41, the first control unit 62b acquires the remaining battery charge of the first battery 49a and the operation state of the second operating device 75. The first control unit 62b acquires the operation state of the second operating device 75 based on an operation signal output from the second operating device 75. The first control unit 62b requests information regarding the remaining battery charge of the first battery 49a from the first operating device 71. The third control unit 74b inputs a signal regarding the remaining battery charge to the first component 61. The first control unit 62b acquires the remaining battery charge of the first battery 49a based on the signal from the third control unit 74b. After performing the process of step S41, the first control unit 62b proceeds to step S42.

[0110] In step S42, if the remaining battery charge acquired in step S41 is equal to or greater than the first threshold, the first control unit 62b proceeds to step S43. If the remaining battery charge acquired in step S41 is less than the first threshold, the first control unit 62b proceeds to step S44.

[0111] In step S43, the first control unit 62b does not operate the first component 61 in accordance with the operation state of the second operation device 75 acquired in step S41. After performing the process of step S43, the first control unit 62b ends the fifth control flow.

[0112] In step S44, the first control unit 62b operates the first component 61 in accordance with the operating state of the second operating device 75 acquired in step S41. For example, in accordance with an operation to change the assist mode of the drive unit 41c from the first assist mode to a second assist mode different from the first assist mode, the first control unit 62b operates the electric motor of the electric transmission 18 so as to reduce the gear ratio of the human-powered vehicle 10. After performing the processing of step S44, the first control unit 62b ends the fifth control flow.

[0113] By the first control unit 62b executing the fifth control flow, the user can confirm that the remaining battery charge of the first battery 49a is less than the first threshold value based on the first component 61 operating in response to the operation of the second operating device 75.

[0114] When an operation signal is output from the first operating device 71, the first control unit 62b may execute a control flow similar to the fifth control flow. By executing the control flow, the first control unit 62b activates the first component 61 in response to the operation signal from the first operating device 71 if the remaining battery charge of the first battery 49a is equal to or greater than a first threshold, and does not activate the first component 61 in response to the operation signal from the first operating device 71 if the remaining battery charge of the first battery 49a is less than the first threshold. The user can activate the first component 61 regardless of the remaining battery charge of the first battery 49a by selectively using the first operating device 71 and the second operating device 75.

[0115] (Seventh embodiment) A control system 80 according to a seventh embodiment will be described. The control system 80 according to the seventh embodiment will be described with reference to Fig. 10 and Fig. 11. The same reference numerals as those in the first to sixth embodiments will be used to designate components common to the first to sixth embodiments, and redundant description will be omitted.

[0116] In this embodiment, the control system 80 is configured such that the fifth control flow shown in Fig. 10 is executed by the fourth control unit 98b of the operating device 70, rather than the first control unit 62b of the component 60. The third control device 74 of the first operating device 71 shown in Fig. 11 includes a third storage unit 74a and a third control unit 94b. The third control unit 94b is configured to be able to communicate with the fourth control unit 98b of the second operating device 75 via wired or wireless communication. For example, the third control unit 94b outputs a signal corresponding to the remaining battery power of the first battery 49a to the fourth control unit 98b at predetermined time intervals.

[0117] The fourth control device 78 of the second operating device 75 includes a fourth storage unit 78a and a fourth control unit 98b. When the second detection unit 77 detects a predetermined operating state, the fourth control unit 98b executes the fifth control flow shown in Fig. 10. In step S44 of the fifth control flow, the fourth control unit 98b outputs an operating signal to the first component 61, thereby operating the first component 61 in accordance with the operating state of the second operating device 75.

[0118] (Eighth embodiment) A control system 80 according to an eighth embodiment will be described. Fig. 12 will be used to describe the control system 80 according to the eighth embodiment. The same reference numerals as those in the first to seventh embodiments will be used to designate components common to the first to seventh embodiments, and redundant description will be omitted.

[0119] In this embodiment, the first component 61 includes one of the electric transmission 18, the electric seat post 41b, the electric suspension 41a, and the drive unit 41c. The second component 63 includes one of the electric transmission 18, the electric seat post 41b, the electric suspension 41a, and the drive unit 41c, which is different from the first component 61.

[0120] Fig. 12 shows an example of a combination of the first component 61 and the second component 63 in this embodiment. In this embodiment, one or two combinations are selected from the combinations shown in Fig. 12. For example, one combination is selected in which the first component 61 is the drive unit 41c and the second component 63 is the electric transmission 18.

[0121] 12, the two combinations are selected so that the components do not overlap. For example, a combination in which the first component 61 is the electric transmission 18 and the second component 63 is the drive unit 41c, and a combination in which the first component 61 is the electric seat post 41b and the second component 63 is the electric suspension 41a are selected.

[0122] By selecting a combination of the first component 61 and the second component 63, the user can easily check the remaining battery charge of the first battery 19a required to operate at least one component of the electric transmission 18, the electric suspension 41a, the electric seat post 41b, and the drive unit 41c.

[0123] (Ninth embodiment) A control system 20 according to a ninth embodiment will be described. Fig. 2 will be used to describe the control system 20 according to the ninth embodiment. The same reference numerals as those in the first to eighth embodiments will be used to designate components common to the first to eighth embodiments, and redundant description will be omitted.

[0124] In this embodiment, the control system 20 includes a component 21 of the human-powered vehicle 10 that includes a first communication unit 24 and receives power from a first battery 19a; an operation device 26 that includes a second communication unit 31 configured to communicate with the first communication unit 24 and receives power from a second battery 19b different from the first battery 19a and is configured to operate the component 21 of the human-powered vehicle 10; and control units 25b and 32b configured to set the power consumption mode of the component 21 to one of a first power consumption mode and a second power consumption mode that consumes less power than the first power consumption mode in response to a user command. In this embodiment, the control units 25b and 32b include at least one of a first control unit 25b configured to execute control of the component 21 and a second control unit 32b configured to execute control of the operation device 26. FIG. 2 shows an example of the control system 20. In the control system 20 shown in FIG. 2, the component 21 includes, for example, an electric transmission 18. The operating device 26 includes a transmission operating device 14 b configured to operate the electric transmission 18 .

[0125] The electric transmission 18 has a plurality of modes related to power consumption. The plurality of modes include a first power consumption mode and a second power consumption mode. In the first power consumption mode, the first control unit 25b operates the electric motor in response to operation of the operating device 26, thereby changing the gear ratio of the human-powered vehicle 10. In the second power consumption mode, the first control unit 25b does not operate the electric motor in response to operation of the operating device 26.

[0126] When the operation device 26 is not operated for a predetermined time or longer while the component 21 is set to the first power consumption mode, the first control unit 25b automatically switches the mode of the component 21 to the second power consumption mode. The first control unit 25b switches between the first power consumption mode and the second power consumption mode in response to a user command. For example, when the operation device 26 is operated while the component 21 is set to the second power consumption mode, the first control unit 25b switches the mode of the component 21 to the first power consumption mode.

[0127] When a predetermined operation is performed on a predetermined device while component 21 is set to the first power consumption mode, first control unit 25b switches the mode of component 21 to the second power consumption mode. For example, when the lever of gear shift operating device 14b is moved to the operating position for a predetermined period of time or longer, first control unit 25b switches the mode of component 21 to the second power consumption mode.

[0128] The first control unit 25b may switch the mode of the component 21 to the second power consumption mode in response to an operation on a device other than the gear shift operating device 14b. The first control unit 25b may switch the mode of the component 21 to the second power consumption mode in response to an operation on a smartphone, for example. When the mode of the component 21 is switched to the second power consumption mode in response to an operation on the smartphone, the first communication unit 24 is configured to be able to communicate with a communication unit of the smartphone. For example, the smartphone outputs a signal to the first communication unit 24 when a predetermined app is launched and a predetermined button is touched. The first control unit 25b switches the mode related to power consumption of the component 21 to the second power consumption mode based on the signal output to the first communication unit 24.

[0129] The first control unit 25b switches the mode related to power consumption of the component 21 to the second power consumption mode in response to a command from the user, thereby quickly switching to the second power consumption mode.

[0130] (Tenth embodiment) A control system 20 according to a tenth embodiment will be described. The control system 20 according to the tenth embodiment will be described with reference to Fig. 2 and Fig. 13. The same reference numerals as those in the first to ninth embodiments will be used to designate components common to the first to ninth embodiments, and redundant description will be omitted.

[0131] In this embodiment, the control unit is configured to intermittently receive a signal from the second communication unit 31 via wireless communication when the mode related to power consumption of the component 21 is set to the second power consumption mode. In this embodiment, the control unit includes a first control unit 25b configured to execute control related to the component 21.

[0132] An example of control executed by first control unit 25b will be described below. Fig. 13 is used to explain the example of control executed by first control unit 25b. First control unit 25b starts a sixth control flow according to the flowchart shown in Fig. 13 when a predetermined condition is satisfied. For example, first control unit 25b starts the sixth control flow when power supply from a predetermined power source starts.

[0133] In step S51, if the mode of component 21 is the second power consumption mode, first control unit 25b proceeds to step S52. If the mode of component 21 is not the second power consumption mode, first control unit 25b ends the sixth control flow.

[0134] In step S52, the first control unit 25b intermittently receives a signal from the second communication unit 31. For example, the first control unit 25b outputs a predetermined signal to the second communication unit 31 of the operating device 26, thereby controlling the second communication unit 31 to output a signal from the second communication unit 31 to the first communication unit 24 at predetermined time intervals. After performing the process of step S52, the first control unit 25b ends the sixth control flow.

[0135] The first control unit 25b executes the sixth control flow, thereby reducing the amount of power consumed by the battery 19 in the second power consumption mode. The reception interval of the intermittent reception in the second power consumption mode may be changed in response to a predetermined operation of an operating device.

[0136] Even when the mode of the component 21 is the first power consumption mode, the first control unit 25b may be configured to intermittently receive a signal from the second communication unit 31. When the first control unit 25b intermittently receives a signal from the second communication unit 31 in the first power consumption mode, the reception interval of the intermittent reception in the second power consumption mode is longer than the reception interval of the intermittent reception in the first power consumption mode.
