[0255] As in Fig. As can be seen in Figure 19, in step S31, the human-powered vehicle component BC1 is started when a triggering event occurs. In this case, the trigger is the time at which the human-powered vehicle component BC1 is supplied with electrical energy.The trigger includes at least one of: providing electrical power to the human-powered vehicle component BC1; connecting an electrical power source to the human-powered vehicle component BC1; connecting an electrical cable connected to the additional human-powered vehicle component BC2; operating an additional control device configured to control the additional human-powered vehicle component BC2; providing the output of the sensor to the human-powered vehicle component BC1; receiving a trigger signal from a trigger input device; and when the human-powered vehicle component BC1 is connected to another device for the first time.In one case, the trigger may, for example, occur when a battery is connected either directly or indirectly to the human-powered vehicle component BC1 such that electrical energy is supplied to the human-powered vehicle component BC1.

The electronic control circuit EC1 proceeds to step S41, S43, or S45 in a case where the device identifier ID0 matches the second device identifier ID2.

[0265] The second device identifier ID2 includes the third device identifier ID3, which indicates the third device DV3 when the second device DV2 includes the third device DV3. The second device identifier ID2 includes the fourth device identifier ID4, which indicates the fourth device DV4 when the second device DV2 includes the fourth device DV4. The second device identifier ID2 includes the fifth device identifier ID5, which indicates the fifth device DV5 when the second device DV2 includes the fifth device DV5.

[0266] In step S40, the electronic control circuit EC1 determines whether the device identifier ID0 matches the third device identifier ID3 of the third device DV3. The electronic control circuit EC1 proceeds to step S41 if the device identifier ID0 matches the third device identifier ID3. The electronic control circuit EC1 proceeds to step S42 if the device identifier ID0 does not match the third device identifier ID3.

[0267] In step S42, the electronic control circuit EC1 determines whether the device identifier ID0 matches the fourth device identifier ID4. The electronic control circuit EC1 proceeds to step S43 if the device identifier ID0 matches the fourth device identifier ID4. The electronic control circuit EC1 proceeds to step S44 if the device identifier ID0 does not match the fourth device identifier ID4.

[0268] In step S44, the electronic control circuit EC1 determines whether the device identifier ID0 matches the fifth device identifier ID5. The electronic control circuit EC1 proceeds to step S45 if the device identifier ID0 matches the fifth device identifier ID5. The electronic control circuit EC1 proceeds to step S46 if the device identifier ID0 does not match the fifth device identifier ID5.

[0269] In step S46, the electronic control circuit EC1 stops the system or executes advertising to establish wireless communication with another device.

[0270] The Fig. 20 to 22 show that in Fig. 19 shows a flowchart of the first control process executed in step S36. As shown in Fig. As can be seen in Figure 20, in step S1, the electronic control circuit EC1 first determines whether the human-powered vehicle component BC1 has already been paired with the first communication device CD1. Specifically, after the electrical power is supplied to the human-powered vehicle component BC1, the electronic control circuit EC1 reads the memory EC12 to determine whether the first pairing information P2 (e.g., identification information) of the first communication device CD1 is stored in the memory EC12.

[0271] In a case where the human-powered vehicle component BC1 has not been paired with the first communication device CD1, the electronic control circuit EC1 proceeds to step S2, where the electronic control circuit EC1 controls the human-powered vehicle component BC1 to enter a first pairing mode. In other words, in a case where the first pairing information P2 (e.g., identification information) of the first communication device CD1 has not been stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the human-powered vehicle component BC1 enters the first pairing mode.

[0272] On the other hand, in a case where the human-powered vehicle component BC1 has been paired with the first communication device CD1, the electronic control circuit EC1 proceeds to step S3, where the electronic control circuit EC1 controls the communicator circuit CC1 to enter the first mode, and the first control process ends. In other words, in a case where pairing information of another component is already stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the human-powered vehicle component BC1 enters the first mode instead of the first pairing mode.Accordingly, the electronic control circuit EC1 is configured to prevent the human-powered vehicle component BC1 from entering the first pairing mode when wireless communication is established between the human-powered vehicle component BC1 and the first communication device CD1.

[0273] In step S3, in a case where the first pairing information P2 of the first communication device CD1 has been stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the communicator circuit CC1 communicates with the electronic control circuit EC1 only when the communicator circuit CC1 receives a wireless signal from the first communication device CD1 that has been paired with the human-powered vehicle component BC1. That is, in the case where the first pairing information P2 of the first communication device CD1 is stored in the memory EC12, the human-powered vehicle component BC1 enters the first mode, so that the first communication device CD1 becomes the paired remote component.In the first pairing mode, the electronic control circuit EC1 is configured to ignore pairing information other than the first pairing information P2 of the first communication device CD1. In the first mode, the communicator circuit CC1 stores the first pairing information P2 of the first communication device CD1 in the memory EC12. Thus, in the first mode, the electronic control circuit EC1 determines whether or not to process the wireless signal by comparing the pairing information contained in the wireless signal with the first pairing information P2 of the first communication device CD1 stored in the memory EC12.

[0274] In step S4, the electronic control circuit EC1 activates the notification device BC12 to generate a first notification in response to the human-powered vehicle component BC1 entering the first pairing mode. For example, the blue LED of the notification device BC12 may begin flashing in a 0.5-second cycle during the first pairing mode. The first control process then proceeds to step S8.

[0275] As in Fig. As can be seen in Figure 21, in step S8, the electronic control circuit EC1 controls the communicator circuit CC1 so that it listens only to the first pairing request signal SG12 and not to the second pairing request signal SG22 or any other pairing request signal. In the illustrated example, the first communication device CD1 is configured to generate the first pairing request signal SG12 in the pairing mode of the first communication device CD1. The first electronic control circuit EC2 controls the first communicator circuit CC2 to wirelessly transmit the first pairing request signal SG12 in the pairing mode.

[0276] In step S8, if the first pairing request signal SG12 is not received, the first control process proceeds to step S9. On the other hand, in a case where the first pairing request signal SG12 is received, the electronic control circuit EC1 establishes wireless communication between the human-powered vehicle component BC1 and the first communication device CD1 that transmitted the first pairing request signal SG12 in a state where the human-powered vehicle component BC1 is in the first pairing mode, and the first control process proceeds to step S10.

[0277] In step S9, the electronic control circuit EC1 determines whether a second predetermined time (for example, 60 seconds) has elapsed. If the second predetermined time has not yet elapsed, the first control process returns to step S8 to continue waiting for the first pairing request signal SG12. If the second predetermined time has elapsed, the electronic control circuit EC1 controls the human-powered vehicle component BC1 to exit the first pairing mode, and the first control process ends.

[0278] In step S10, the electronic control circuit EC1 stores the first pairing information P2 included in the first pairing request signal SG12 in the memory EC12. As mentioned above, the first pairing information P2 identifies the first communication device CD1. Thus, the wireless signal generated by the first wireless communicator circuit WC2 includes the first pairing information P2 received by the communicator circuit CC1, so that the electronic control circuit EC1 can determine the source of the wireless signal as originating from the first wireless communicator circuit WC2 of the first communication device CD1. In step S10, the electronic control circuit EC1 stores, for example, the identification information of the first pairing information P2 included in the first pairing request signal SG12 in the memory EC12.In step S10, the electronic control circuit EC1 receives the cryptographic key information of the first pairing information P2, but does not store the cryptographic key information in the memory EC12. Therefore, the electronic control circuit EC1 does not perform bonding in step S10. The communicator circuit CC1 may transmit a confirmation signal to the first wireless communicator circuit WC2 after receiving and storing the first pairing information P2. The first communication device CD1 may output a notification to the user. For example, the first communication device CD1 may light up an LED of a notification device of the first communication device CD1 to inform a user that the first pairing information P2 (e.g., identification information) has been received and stored in the memory EC12.Next, the first control process proceeds to step S11.

[0279] In step S11, the electronic control circuit EC1 controls the communicator circuit CC1 to transmit the first signal SG1 in response to the first pairing request signal SG12. For example, the electronic control circuit EC1 controls the communicator circuit CC1 to wirelessly transmit the first wireless signal SG11 in response to the first pairing request signal SG12. The electronic control circuit EC1 controls the communicator circuit CC1 to wirelessly transmit the first pairing response signal SG13 in response to the first pairing request signal SG12. The first pairing response signal SG13 includes the pairing information P1 of the human-powered vehicle component BC1. The first pairing response signal SG13 can be encrypted using the first pairing information P2 included in the first pairing request signal SG12.The first communication device CD1 wirelessly receives the first pairing response signal SG13. In the first communication device CD1, the first electronic control circuit EC2 stores the pairing information P1 included in the first pairing response signal SG13 in the memory EC32. Next, the first control process proceeds to step S12.

[0280] In step S12, the electronic control circuit EC1 activates the notification device BC12 to generate a second notification in a state where the human-powered vehicle component BC1 has been successfully paired. The term "successfully paired" as used herein refers to a situation where the pairing information (e.g., identification information) of another device has been stored in the memory EC12 of the human-powered vehicle component BC1. Preferably, the second notification is different from the first notification. For example, if the first notification is a flashing blue light, the second notification may be a solid light of any color or a flashing light other than a blue light. Step S12 may be omitted. In such modifications, step S13 is executed after step S11.Next, the first control process proceeds to step S13.

[0281] In step S13, the electronic control circuit EC1 determines whether the first pairing signal SG14 has been received to confirm that the human-powered vehicle component BC1 has been paired with the first communication device CD1. In the present embodiment, the first electronic control circuit EC2 controls the first wired communicator circuit WC2 to wirelessly transmit the first pairing signal SG14 in response to the first pairing response signal SG13. Alternatively, the first pairing signal SG14 may be generated in response to the first user input at the first user interface 24A or 24B provided on the first communication device CD1 being paired. To generate the first pairing signal SG14, the first user interface 24A or 24B may be operated for a predetermined period of time, for example, such as 0.5 seconds or more.

[0282] In a case where the first pairing signal SG14 is not received in step S13, the first control process proceeds to step S14. In step S14, the electronic control circuit EC1 determines whether a third predetermined time (for example, two to three seconds) has elapsed since the start of step S13. If the third predetermined time has not elapsed since the start of step S13, the first control process returns to step S13 to continue waiting for the first pairing signal SG14. If the third predetermined time has elapsed since the start of step S13 without a pairing signal being detected, the electronic control circuit EC1 controls the human-powered vehicle component BC1 to exit the first pairing mode, and the first control process ends.If a pairing signal has been received in step S13 before the third predetermined time has elapsed, the first control process proceeds to step S15.

[0283] In step S15, the electronic control circuit EC1 stores the first pairing information P2 included in the first pairing signal SG14 in the memory EC12. As already mentioned, the first pairing information P2 identifies the first communication device CD1. Thus, the wireless signal generated by the first wireless communicator circuit WC2 includes the first pairing information P2 received by the communicator circuit CC1, so that the electronic control circuit EC1 can determine the source of the wireless signal as originating from the first wireless communicator circuit WC2 of the first communication device CD1. Furthermore, the first pairing information P2 includes the cryptographic key information used to encrypt a signal.In step S15, the electronic control circuit EC1 stores, for example, the cryptographic key information or both the identification information and the cryptographic key information of the first pairing information P2 included in the first pairing signal SG14 in the memory EC12. Namely, the electronic control circuit EC1 performs bonding in step S15. However, step S15 or both step S14 and step S15 may be omitted from the flowchart of the first control process. In such modifications, the first pairing request signal SG12 includes the first pairing information P2 including both the identification information and the cryptographic key information of the first communication device CD1.In step S10, the electronic control circuit EC1 stores in the memory EC12 both the identification information and the cryptographic key information included in the first pairing information P2 included in the first pairing request signal SG12. Namely, the electronic control circuit EC1 can perform bonding in step S10. The communicator circuit CC1 can transmit a confirmation signal to the first wireless communicator circuit WC2 after receiving and storing the first pairing information P2. Next, the first control process proceeds to step S16.

[0284] In step S16, the electronic control circuit EC1 activates the notification device BC12 to generate a third notification in response to the completion of the first pairing mode for establishing wireless communication between the human-powered vehicle component BC1 and at least one remote component. The term "establishing wireless communication" used herein refers to a situation in which the memory EC12 stores at least one piece of pairing information (e.g., identification information).That is, the term “establishing wireless communication” used here refers to a situation in which the human-powered vehicle component BC1 has exited the first pairing mode and entered the first mode, so that the human-powered vehicle component BC1 can be operated by the paired remote component with the pairing information stored in the memory EC12.

[0285] In step S17, the electronic control circuit EC1 goes into the Fig. 22 after the pairing between the human-powered vehicle component BC1 and the first communication device CD1 is completed.

[0286] With reference to Fig. 22, the first mode will now be discussed, in which the human-powered vehicle component BC1 is operated using the first communication device CD1 that has been paired with the human-powered vehicle component BC1. The first mode will be explained based on the case where the human-powered vehicle component BC1 includes the gear changer 12 and where the human-powered vehicle component BC1 has been paired with the first communication device CD1. However, the first mode can also be used with other components.

[0287] In the first mode of Fig. 22, the control process may be a separate control process or a subroutine of step S3 of Fig. 20 or step S17 of Fig. 21. Basically, in a manual mode of the human-powered vehicle control system 10, the communicator circuit CC1 wirelessly receives the first control signal CS11 or CS12 encrypted based on pairing information of the second operating device 26 paired with the human-powered vehicle component BC1. In the automatic mode of the human-powered vehicle control system 10, the communicator circuit CC1 wirelessly receives the first control signal CS11 or CS12 encrypted based on the pairing information P1 stored in the memory EC22 of the first electronic control circuit EC2.In other words, in the examples shown, the communicator circuit CC1 of the human-powered vehicle component BC1 is configured to wirelessly receive the first control signal CS11 or CS12 containing the first pairing information P2 from the first wireless communicator circuit WC2 of the first communication device CD1.

[0288] As in Fig. 22, the electronic control circuit EC1 first determines in step S21 whether the human-powered vehicle component BC1 is in the first mode. In a case where the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 has entered the first mode, the method proceeds to step S22. If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is not in the first mode, the method returns to step S31 of Fig. 19 back.

[0289] In step S22, the electronic control circuit EC1 determines whether the communicator circuit CC1 is receiving a signal via an electrical cable or a wireless communication channel. If the communicator circuit CC1 detects a signal (e.g., the first control signal CS11 or CS12) transmitted via the electrical cable, the process proceeds to step S23. If the communicator circuit CC1 detects a wireless signal, the electronic control circuit EC1 determines whether the wireless signal is transmitted from the paired device that has been paired with the human-powered vehicle component BC1. If the communicator circuit CC1 detects the wireless signal, the electronic control circuit EC1 determines whether the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12 of the human-powered vehicle component BC1.In a case where the first control signal CS11 or CS12 is not encrypted using the pairing information stored in the memory EC12, the process returns to step S21. In a case where the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12, the electronic control circuit EC1 decrypts the first control signal CS11 or CS12 based on the pairing information stored in the memory EC12. Then, the process proceeds to step S23.

[0290] For example, in step S23, the electronic control circuit EC1 controls the electric actuator 12E of the gear changer 12 via the actuator driver 12F based on the first control signal CS11 or CS12. In a case where the first control signal CS11 or CS12 indicates the change in the gear position of the gear changer 12, the electronic control circuit EC1 controls the electric actuator 12E to move the movable member 12B via the actuator driver 12F based on the first control signal CS11 or CS12.

[0291] The one in the Fig. The first control process illustrated in Figures 19 to 21 may be modified so that the first control process can be terminated by the user at any time. For example, the user interface BC11 may be operated by a user at any time to terminate the first control process. In other words, the user may terminate the first pairing mode via the user interface BC11. The first pairing mode may be terminated based on an operation of an operation device such as the first operation device 24, the second operation device 26, or the third operation device 28. If the user exits the first pairing mode via the user interface BC11 before receiving a pairing signal, all pairing information stored in the memory EC12 is deleted from the memory EC12.

[0292] The Fig. 23 to 34 show the flowchart of the second control processes used in the Fig. 19 are executed. The second control process includes: the control of the human-powered vehicle component BC1 based on the first control signal CS11 or CS12; and the pairing process performed between the human-powered vehicle component BC1 and the second communication device CD2. As shown in Fig. 19, for example, the second control process includes a third control process that is executed in a case where the second device DV2 includes the third device DV3. The second control process includes a fourth control process that is executed in a case where the second device DV2 includes the fourth device DV4. The second control process includes a fifth control process that is executed in a case where the second device DV2 includes the fifth device DV5. The second control process includes a sixth control process that is executed in a case where the second device DV2 does not include one of the third device DV3, the fourth device DV4, and the fifth device DV5. The third control process corresponds to the Fig. 8 and Fig. 14. The fourth control process corresponds to the embodiment shown in the Fig. 9 and Fig. 15. The fifth control process corresponds to the embodiment shown in the Fig. 10 and Fig. 16 illustrated embodiment.

[0293] The Fig. 23 to 25 show the flowchart of the third control process used in the Fig. 19 is executed. As shown in Fig. 23, the electronic control circuit EC1 first determines in step S41 whether the human-powered vehicle component BC1 has already been paired with the second communication device CD2. Specifically, after the electric power is supplied to the human-powered vehicle component BC1, the electronic control circuit EC1 reads the memory EC12 to determine whether the second pairing information P4 (e.g., identification information) of the second communication device CD2 is stored in the memory EC12. In a case where the human-powered vehicle component BC1 has not been paired with the second communication device CD2, the electronic control circuit EC1 proceeds to step S42, in which the electronic control circuit EC1 controls the human-powered vehicle component BC1 to enter a second pairing mode.In other words, in a case where the second pairing information P4 (e.g., identification information) of the second communication device CD2 has not been stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the human-powered vehicle component BC1 enters the second pairing mode. On the other hand, in a case where the human-powered vehicle component BC1 has been paired with the second communication device CD2, the electronic control circuit EC1 proceeds to step S43, where the electronic control circuit EC1 controls the communicator circuit CC1 to enter the second mode (e.g., the third mode), and the third control process ends.In other words, in a case where pairing information of another component is already stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the human-powered vehicle component BC1 enters the second mode (for example, the third mode) instead of the second pairing mode. Accordingly, the electronic control circuit EC1 is configured to prevent the human-powered vehicle component BC1 from entering the second pairing mode in a state where wireless communication is established between the human-powered vehicle component BC1 and the second communication device CD2.

[0294] In step S43, in a case where the second pairing information P4 of the second communication device CD2 has been stored in the memory EC12, the electronic control circuit EC1 controls the communicator circuit CC1 so that the communicator circuit CC1 communicates with the electronic control circuit EC1 only when the communicator circuit CC1 receives a wireless signal from the second communication device CD2 that has been paired with the human-powered vehicle component BC1. That is, in the case where the second pairing information P4 of the second communication device CD2 is stored in the memory EC12, the human-powered vehicle component BC1 enters the second mode, so that the second communication device CD2 becomes the paired remote component.In the second pairing mode, the electronic control circuit EC1 is configured to ignore pairing information other than the second pairing information P4 of the second communication device CD2. In the second mode, the communicator circuit CC1 stores the second pairing information P4 of the second communication device CD2 in the memory EC12. Thus, in the second mode, the electronic control circuit EC1 determines whether or not to process the wireless signal by comparing the pairing information contained in the wireless signal with the second pairing information P4 of the second communication device CD2 stored in the memory EC12.

[0295] In step S44, the electronic control circuit EC1 activates the notification device BC12 to generate a first notification in response to the human-powered vehicle component BC1 entering the second pairing mode. For example, the blue LED of the notification device BC12 may begin flashing in a 0.5-second cycle during the second pairing mode. The third control process then proceeds to step S48.

[0296] As in Fig. As shown in Figure 24, in step S48, the electronic control circuit EC1 controls the communicator circuit CC1 so that it listens only to the second pairing request signal SG22 and not to the first pairing request signal SG12 or any other pairing request signal. In the illustrated example, the second communication device CD2 is configured to generate the second pairing request signal SG22 in the pairing mode of the second communication device CD2. The second electronic control circuit EC4 controls the second communicator circuit CC4 to wirelessly transmit the second pairing request signal SG22 in the pairing mode.

[0297] In step S48, in a case where the second pairing request signal SG22 is not received, the third control process proceeds to step S49. On the other hand, in a case where the second pairing request signal SG22 is received, the electronic control circuit EC1 establishes wireless communication between the human-powered vehicle component BC1 and the second communication device CD2 that transmitted the second pairing request signal SG22 in a state where the human-powered vehicle component BC1 is in the second pairing mode, and the third control process proceeds to step S50.

[0298] In step S49, the electronic control circuit EC1 determines whether a second predetermined time (for example, two to three seconds) has elapsed. If the second predetermined time has not yet elapsed, the third control process returns to step S48 to continue waiting for the second pairing request signal SG22. When the second predetermined time has elapsed, the electronic control circuit EC1 controls the human-powered vehicle component BC1 to terminate the second pairing mode, and the third control process ends. Step S9 may be omitted if necessary or desired. In particular, step S49 may be omitted when the communicator circuit CC1 operates intermittently in the second pairing mode.

[0299] In step S50, the electronic control circuit EC1 stores the second pairing information P4 included in the second pairing request signal SG22 in the memory EC12. Here, as mentioned above, the second pairing information P4 identifies the second communication device CD2. Thus, the wireless signal generated by the first wireless communicator circuit WC4 includes the second pairing information P4 received by the communicator circuit CC1, so that the electronic control circuit EC1 can determine the source of the wireless signal as originating from the first wireless communicator circuit WC4 of the second communication device CD2. In step S50, the electronic control circuit EC1 stores, for example, the identification information of the second pairing information P4 included in the second pairing request signal SG22 in the memory EC12.At this time, the notification device BC12 is not illuminated. In step S50, the electronic control circuit EC1 receives the cryptographic key information of the second pairing information P4, but does not store the cryptographic key information in the memory EC12. Therefore, the electronic control circuit EC1 does not perform bonding in step S50. The communicator circuit CC1 may send a confirmation signal to the first wireless communicator circuit WC4 after receiving and storing the second pairing information P4. The second communication device CD2 may issue a notification to the user.For example, the second communication device CD2 may illuminate an LED of a notification device of the second communication device CD2 to inform a user that the second pairing information P4 (e.g., identification information) has been received and stored in the memory EC12. Next, the third control process proceeds to step S51.

[0300] In step S51, the electronic control circuit EC1 controls the communicator circuit CC1 to transmit the second signal SG2 in response to the second pairing request signal SG22. For example, the electronic control circuit EC1 controls the communicator circuit CC1 to wirelessly transmit the second wireless signal SG21 in response to the second pairing request signal SG22. The electronic control circuit EC1 controls the communicator circuit CC1 to wirelessly transmit the second pairing response signal SG23 in response to the second pairing request signal SG22. The second pairing response signal SG23 includes the pairing information P1 of the human-powered vehicle component BC1. The second pairing response signal SG23 can be encrypted using the second pairing information P4 included in the second pairing request signal SG22.The second communication device CD2 wirelessly receives the second pairing response signal SG23. In the second communication device CD2, the second electronic control circuit EC4 stores the pairing information P1 included in the second pairing response signal SG23 in the memory EC42. Next, the third control process proceeds to step S52.

[0301] In step S52, the electronic control circuit EC1 activates the notification device BC12 to generate a second notification in a state where the human-powered vehicle component BC1 has been successfully paired. Preferably, the second notification is different from the first notification. For example, if the first notification is a flashing blue light, the second notification may be a solid light of any color or a flashing light other than a blue light. Step S52 may be omitted. In such modifications, step S53 is executed after step S51. Next, the third control process proceeds to step S53.

[0302] In step S53, the electronic control circuit EC1 determines whether the second pairing signal SG24 has been received to confirm that the human-powered vehicle component BC1 has been paired with the second communication device CD2. In the present embodiment, the second electronic control circuit EC4 controls the first wired communicator circuit WC4 to wirelessly transmit the second pairing signal SG24 in response to the second pairing response signal SG23. Alternatively, the second pairing signal SG24 may be generated in response to a user input at the first input device SW1 provided on the second communication device CD2 being paired. To generate the second pairing signal SG24, for example, the first user interface 24A or 24B may be operated for a predetermined period of time, such as 0.5 seconds or more.

[0303] If the second pairing signal SG24 has not been received in step S53, the third control process proceeds to step S54. In step S54, the electronic control circuit EC1 determines whether a third predetermined time (for example, two to three seconds) has elapsed since the start of step S53. If the third predetermined time has not elapsed since the start of step S53, the third control process returns to step S53 to continue waiting for the second pairing signal SG24. If the third predetermined time has elapsed since the start of step S53 without a pairing signal being detected, the electronic control circuit EC1 controls the human-powered vehicle component BC1 to exit the second pairing mode, and the third control process ends. If a pairing signal is received in step S53 before the third predetermined time has elapsed, the third control process proceeds to step S55.

[0304] In step S55, the electronic control circuit EC1 stores the second pairing information P4 included in the second pairing signal SG24 in the memory EC12. Here, as mentioned above, the second pairing information P4 identifies the second communication device CD2. Thus, the wireless signal generated by the first wireless communicator circuit WC4 includes the second pairing information P4 received by the communicator circuit CC1, so that the electronic control circuit EC1 can determine the source of the wireless signal as originating from the first wireless communicator circuit WC4 of the second communication device CD2. Furthermore, the second pairing information P4 includes the cryptographic key information used to encrypt a signal.In step S55, the electronic control circuit EC1 stores, for example, the cryptographic key information or both the identification information and the cryptographic key information of the second pairing information P4 included in the second pairing signal SG24 in the memory EC12. The electronic control circuit EC1 performs bonding in step S55. However, step S55 or both step S54 and step S55 may be omitted from the flowchart of the third control process. In such modifications, the second pairing request signal SG22 includes the second pairing information P4 including both the identification information and the cryptographic key information of the second communication device CD2.In step S50, the electronic control circuit EC1 stores in the memory EC12 both the identification information and the cryptographic key information included in the second pairing information P4 included in the second pairing request signal SG22. Namely, the electronic control circuit EC1 can perform bonding in step S50. The communicator circuit CC1 can send a confirmation signal to the first wireless communicator circuit WC4 after receiving and storing the second pairing information P4. Next, the third control process proceeds to step S56.

[0305] In step S56, the electronic control circuit EC1 activates the notification device BC12 to generate a third notification in response to the completion of the second pairing mode for establishing wireless communication between the human-powered vehicle component BC1 and at least one remote component. The term "establishing wireless communication" used herein refers to a situation in which the memory EC12 stores at least one piece of pairing information (e.g., identification information).That is, the term “establishing wireless communication” used here refers to a situation in which the human-powered vehicle component BC1 has exited the second pairing mode and entered the second mode, so that the human-powered vehicle component BC1 can be operated by the paired remote component with the pairing information stored in the memory EC12.

[0306] In step S57, the electronic control circuit EC1 goes into the Fig. 25 after the pairing between the human-powered vehicle component BC1 and the second communication device CD2 is completed.

[0307] With reference to Fig. 25, the second mode will now be discussed, in which the human-powered vehicle component BC1 is operated using the second communication device CD2 that has been paired with the human-powered vehicle component BC1. The second mode will be explained based on the case where the human-powered vehicle component BC1 includes the gear changer 12 and the human-powered vehicle component BC1 has been paired with the second communication device CD2. However, the second mode can also be used with other components.

[0308] In the second mode of Fig. 25, the control process may be a separate control process or a subroutine of step S43 of Fig. 23 or step S57 of Fig. 24. Basically, the communicator circuit CC1 receives the first control signal CS11 or CS12 via the second device DV2 and the second electrical cable CB21 from the first operating device 24. As in the Fig. However, in the first mode illustrated in Figure 22, the communicator circuit CC1 may be configured to wirelessly receive the first control signal CS11 or CS12 encrypted on the basis of the pairing information P1 stored in the memory EC22 of the first electronic control circuit EC2.

[0309] As in Fig. 25, the electronic control circuit EC1 first determines in step S61 whether the human-powered vehicle component BC1 is in the second mode (e.g., the third mode). If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is in the second mode (e.g., the third mode), the method proceeds to step S62. If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is not in the second mode (e.g., the third mode), the method returns to step S31 of Fig. 19 back.

[0310] In step S62, the electronic control circuit EC1 determines whether the communicator circuit CC1 is receiving a signal via an electrical cable or a wireless communication channel. If the communicator circuit CC1 detects a signal (e.g., the first control signal CS11 or CS12) transmitted via the electrical cable, the process proceeds to step S63. If the communicator circuit CC1 detects a wireless signal, the electronic control circuit EC1 determines whether the wireless signal is being transmitted from the paired device that has been paired with the human-powered vehicle component BC1.In a case where the communicator circuit CC1 detects the first control signal CS11 or CS12, the electronic control circuit EC1 determines whether the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12 of the human-powered vehicle component BC1. In a case where the first control signal CS11 or CS12 is not encrypted using the pairing information stored in the memory EC12, the process returns to step S21. In a case where the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12, the electronic control circuit EC1 decrypts the first control signal CS11 or CS12 based on the pairing information stored in the memory EC12. Then, the process proceeds to step S63.

[0311] In step S63, the electronic control circuit EC1 controls as in step S23 of Fig. 22 the electric actuator 12E of the gear changer 12 via the actuator driver 12F based on the first control signal CS11 or CS12.

[0312] The one in the Fig. The third control process illustrated in Figures 23 to 25 can be modified so that the third control process can be terminated by the user at any time. For example, the user interface BC11 can be operated by a user at any time to terminate the third control process. In other words, the user can terminate the second pairing mode via the user interface BC11. The first pairing mode can be terminated based on an operation of an operating device such as the first operating device 24, the second operating device 26, or the third operating device 28. If the user exits the second pairing mode via the user interface BC11 before receiving a pairing signal, all pairing information stored in the memory EC12 is deleted from the memory EC12.

[0313] The Fig. 26 to 28 show the flowchart of the fourth control process used in the Fig. 19 is executed. The steps S71, S72, S74 and S78 to S86 of the Fig. 26 and Fig. 27 are the same as steps S41, S42, S44 and S48 to S56 of the Fig. 23 and Fig. 24. Therefore, for the sake of brevity, they are not described in detail here.

[0314] As in Fig. As can be seen in Figure 26, in a case where the second pairing information P4 of the second communication device CD2 has been stored in the memory EC12, the human-powered vehicle component BC1 enters the second mode (for example, the fourth mode) in step S73. As shown in Fig. 27, the human-powered vehicle component BC1 enters the second mode (for example, the fourth mode) in step S87 after step S86.

[0315] As in Fig. 28, the electronic control circuit EC1 first determines in step S91 whether the human-powered vehicle component BC1 is in the second mode (e.g., the fourth mode). If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 has entered the second mode (e.g., the fourth mode), the method proceeds to step S92. If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is not in the second mode (e.g., the fourth mode), the method returns to step S31 of Fig. 19 back.

[0316] In step S92, the electronic control circuit EC1 determines whether the communicator circuit CC1 is receiving a signal via an electrical cable or a wireless communication channel. If the communicator circuit CC1 detects a signal transmitted via the electrical cable (for example, the first control signal CS11 or CS12), the process proceeds to step S93. If the communicator circuit CC1 detects a wireless signal, the electronic control circuit EC1 determines whether the wireless signal is transmitted from the paired device that has been paired with the human-powered vehicle component BC1. If the communicator circuit CC1 detects the first control signal CS11 or CS12, the electronic control circuit EC1 determines whether the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12 of the human-powered vehicle component BC1.In a case where the first control signal CS11 or CS12 is not encrypted using the pairing information stored in the memory EC12, the process returns to step S21. In a case where the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12, the electronic control circuit EC1 decrypts the first control signal CS11 or CS12 based on the pairing information stored in the memory EC12. Then, the process proceeds to step S93.

[0317] In step S93, the electronic control circuit EC1 controls as in step S23 of Fig. 22 the electric actuator 12E of the gear changer 12 via the actuator driver 12F based on the first control signal CS11 or CS12.

[0318] The one in the Fig. The fourth control process illustrated in Figures 26 to 28 can be modified so that the fourth control process can be terminated by the user at any time. For example, the user interface BC11 can be operated by a user at any time to terminate the fourth control process. In other words, the user can terminate the second pairing mode via the user interface BC11. The first pairing mode can be terminated based on an operation of an operating device such as the first operating device 24, the second operating device 26, or the third operating device 28. If the user exits the second pairing mode via the user interface BC11 before receiving a pairing signal, all pairing information stored in the memory EC12 is deleted from the memory EC12.

[0319] The Fig. 29 to 31 show the flowchart of the fifth control process used in the Fig. 19 is executed. The steps S101, S102, S104 and S108 to S116 of the Fig. 29 and Fig. 30 are the same as steps S41, S42, S44 and S48 to S56 of the Fig. 23 and Fig. 24. Therefore, for the sake of brevity, they are not described in detail here.

[0320] As in Fig. As can be seen in Figure 29, in a case where the second pairing information P4 of the second communication device CD2 has been stored in the memory EC12, the human-powered vehicle component BC1 enters the second mode (for example, the fifth mode) in step S103. As shown in Fig. 30, the human-powered vehicle component BC1 enters the second mode (e.g., the fifth mode) in step S117 after step S116.

[0321] As in Fig. 31, the electronic control circuit EC1 first determines in step S121 whether the human-powered vehicle component BC1 is in the second mode (for example, the fifth mode). If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 has entered the second mode (for example, the fifth mode), the method proceeds to step S122. If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is not in the second mode (for example, the fifth mode), the method returns to step S31 of Fig. 19 back.

[0322] In step S122, the electronic control circuit EC1 determines whether the communicator circuit CC1 is receiving a signal via an electrical cable or a wireless communication channel. If the communicator circuit CC1 detects a signal transmitted via the electrical cable (for example, the first control signal CS11 or CS12), the process proceeds to step S123. If the communicator circuit CC1 detects a wireless signal, the electronic control circuit EC1 determines whether the wireless signal is being transmitted from the paired device that has been paired with the human-powered vehicle component BC1.In a case where the communicator circuit CC1 detects the first control signal CS11 or CS12, the electronic control circuit EC1 determines whether the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12 of the human-powered vehicle component BC1. In a case where the first control signal CS11 or CS12 is not encrypted using the pairing information stored in the memory EC12, the process returns to step S21. In a case where the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12, the electronic control circuit EC1 decrypts the first control signal CS11 or CS12 based on the pairing information stored in the memory EC12. Then, the process proceeds to step S123.

[0323] In step S123, the electronic control circuit EC1 controls as in step S23 of Fig. 22 the electric actuator 12E of the gear changer 12 via the actuator driver 12F based on the first control signal CS11 or CS12.

[0324] The one in the Fig. The fifth control process illustrated in Figures 29 to 31 can be modified so that the fifth control process can be terminated by the user at any time. For example, the user interface BC11 can be operated by a user at any time to terminate the fifth control process. In other words, the user can terminate the second pairing mode via the user interface BC11. The first pairing mode can be terminated based on an operation of an operating device such as the first operating device 24, the second operating device 26, or the third operating device 28. If the user exits the second pairing mode via the user interface BC11 before receiving a pairing signal, all pairing information stored in the memory EC12 is deleted from the memory EC12.

[0325] The Fig. 32 to 34 show the flowchart of the sixth control process used in the Fig. 19 is executed. The steps S131, S132, S134 and S138 to S146 of the Fig. 32 and Fig. 33 are the same as steps S41, S42, S44 and S48 to S56 of the Fig. 23 and Fig. 24. Therefore, for the sake of brevity, they are not described in detail here.

[0326] In step S33, the human-powered vehicle component BC1 may be configured to restrict the action (e.g., transmitting signals) of the human-powered vehicle component BC1 based on the device identifier of the human-powered vehicle component BC1, if necessary or desired. The human-powered vehicle component BC1 may be configured to restrict the action of the human-powered vehicle component BC1 based on a voltage supplied by a power source, if necessary or desired.For example, the human-powered vehicle component BC1 may be configured to restrict the action (e.g., gear shifting, all actions) of the human-powered vehicle component BC1 in a case where the voltage supplied from the electric power source is higher than or equal to a predetermined voltage. Moreover, the human-powered vehicle component BC1 may be configured to restrict the action of the human-powered vehicle component BC1 in a state where electric power is supplied from an external electric power source (e.g., the first electric power source PS1) in a case where a directly mounted electric power source (e.g., the one shown in FIG. Fig. 11) is disassembled after the directly mounted electric power source is mounted to the human-powered vehicle component BC1. Furthermore, the human-powered vehicle component BC1 may be configured to restrict the action of the human-powered vehicle component BC1 in a state where an electric wire (e.g., the first electric wire CB11 or the second electric wire CB21) electrically connected to another electric power source is connected to the human-powered vehicle component BC1 in a case where a directly mounted electric power source (e.g., the first electric wire CB11 or the second electric wire CB21) is connected to the human-powered vehicle component BC1. Fig. 11) is disassembled after the directly mounted electric power source is mounted on the human-powered vehicle component BC1.

[0327] As in Fig. As can be seen in Figure 32, in a case where the second pairing information P4 of the second communication device CD2 has been stored in the memory EC12, the human-powered vehicle component BC1 enters the second mode (for example, the sixth mode) in step S133. As shown in Fig. 33, the human-powered vehicle component BC1 enters the second mode (e.g., the sixth mode) in step S147 after step S146.

[0328] As in Fig. 34, the electronic control circuit EC1 first determines in step S151 whether the human-powered vehicle component BC1 is in the second mode (for example, the sixth mode). If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 has entered the second mode (for example, the sixth mode), the process proceeds to step S152. If the electronic control circuit EC1 concludes that the human-powered vehicle component BC1 is not in the second mode (for example, the sixth mode), the process returns to step S31 of Fig. 19 back.

[0329] In step S152, the electronic control circuit EC1 determines whether the communicator circuit CC1 is receiving a signal via an electrical cable or a wireless communication channel. If the communicator circuit CC1 detects a signal transmitted via the electrical cable (for example, the first control signal CS11 or CS12), the process proceeds to step S123. If the communicator circuit CC1 detects a wireless signal, the electronic control circuit EC1 determines whether the wireless signal is being transmitted from the paired device that has been paired with the human-powered vehicle component BC1.In a case where the communicator circuit CC1 detects the first control signal CS11 or CS12, the electronic control circuit EC1 determines whether the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12 of the human-powered vehicle component BC1. In a case where the first control signal CS11 or CS12 is not encrypted using the pairing information stored in the memory EC12, the process returns to step S21. In a case where the first control signal CS11 or CS12 is encrypted using the pairing information stored in the memory EC12, the electronic control circuit EC1 decrypts the first control signal CS11 or CS12 based on the pairing information stored in the memory EC12. Then, the process proceeds to step S153.

[0330] In step S153, the electronic control circuit EC1 controls as in step S23 of Fig. 22 the electric actuator 12E of the gear changer 12 via the actuator driver 12F based on the first control signal CS11 or CS12.

[0331] The one in the Fig. The sixth control process illustrated in Figures 32 to 34 can be modified so that the sixth control process can be terminated by the user at any time. For example, the user interface BC11 can be operated by a user at any time to terminate the sixth control process. In other words, the user can terminate the second pairing mode via the user interface BC11. The first pairing mode can be terminated based on an operation of an operation device such as the first operation device 24, the second operation device 26, or the third operation device 28. If the user exits the second pairing mode via the user interface BC11 before receiving a pairing signal, all pairing information stored in the memory EC12 is deleted from the memory EC12.

[0332] In some modifications, the human-powered vehicle component BC1 may be configured to select one of the predetermined action patterns based on the device identifier of the human-powered vehicle component BC1.

[0333] In the Fig. In the first pairing process illustrated in Figures 19 to 21, the notification device BC12 outputs the first notification, the second notification, and the third notification in steps S7, S12, and S12. However, at least one of the first to third notifications may be omitted from the pairing process if necessary or desired.

[0334] In the Fig. In the pairing process illustrated in Figures 19 to 21, the human-powered vehicle component BC1 wirelessly receives the first pairing signal SG14 in step S13 after transmitting the first pairing response signal SG13. However, steps S13 and S14 may be omitted from the pairing process if necessary or desired.

[0335] In the Fig. In the pairing process illustrated in Figures 19 to 21, the human-powered vehicle component BC1 is configured to serve as a Bluetooth (registered trademark) central unit, while the first communication device CD1 is configured to serve as a Bluetooth (registered trademark) peripheral unit. However, the human-powered vehicle component BC1 may be configured to serve as a Bluetooth (registered trademark) peripheral unit if necessary or desired. The first communication device CD1 may be configured to serve as a Bluetooth (registered trademark) central unit if necessary or desired.

[0336] While the present invention focuses on the pairing process between the human-powered vehicle component BC1, including the gearshift 12, and another device, the pairing process may be applied to any other human-powered vehicle component and to remote components equipped with wireless communication. For example, the suspension 16 may be equipped with a wireless communicator circuit that pairs with the wireless communicator circuit of the first communication device CD1 or the second communication device CD2, allowing the remote component to wirelessly communicate with the suspension 16 to adjust the settings of the suspension 16.The suspension 18 may be provided with a wireless communicator circuit paired with the wireless communicator circuit of the first communication device CD1 or the second communication device CD2, such that the remote component can wirelessly communicate with the suspension 18 to adjust the settings of the suspension 18. Likewise, for example, the adjustable seat post 20 may be provided with a wireless communicator circuit paired with a wireless communicator circuit of a remote component (e.g., the first communication device CD1 or the second communication device CD2), such that the remote component can wirelessly communicate with the adjustable seat post 20 to adjust settings of the adjustable seat post 20.Furthermore, for example, the auxiliary drive unit 22, 30 or 32 may be provided with a wireless communicator circuit that is paired with a wireless communicator circuit of a remote component (for example, the first communication device CD1 or the second communication device CD2) so that the remote component can wirelessly communicate with the auxiliary drive unit 22, 30 or 32 to adjust settings of the auxiliary drive unit 22, 30 or 32.

[0337] In the Fig. 8 and Fig. In the embodiment shown in Figure 14 and its modifications, the first device DV1 is provided separately from the first communication device CD1. The first device DV1 is electrically connected to the first communication device CD1 via the first electrical cable CB13. As shown in Fig. However, as can be seen in Figure 35, the first device DV1 may include the first communication device CD1 if necessary or desired.

[0338] The first communication device CD1 can be included in a first auxiliary drive system DS1 configured to assist the locomotion of the human-powered vehicle B. The first auxiliary drive system DS1 has a first auxiliary system identifier. The first auxiliary drive system DS1 includes the auxiliary drive unit 22 and the first communication device CD1. The human-powered vehicle component BC1 can be connected to the first communication device CD1 via an electrical cable. The first control signal CS11 or CS12 can be transmitted from the first communication device CD1 to the human-powered vehicle component BC1 via the electrical cable.

[0339] As in Fig. 36, the second communication device CD2 may be included in a second auxiliary drive system DS2 configured to assist the propulsion of the human-powered vehicle B. The second auxiliary drive system DS2 has a second auxiliary system identifier that is different from the first auxiliary system identifier. The second auxiliary drive system DS2 includes the auxiliary drive unit 30 and the second communication device CD2. The human-powered vehicle component BC1 may be connected to the second communication device CD2 via an electrical cable. The first control signal CS11 or CS12 may be transmitted from the second communication device CD2 to the human-powered vehicle component BC1 via the electrical cable.

[0340] In the Fig. 9 and Fig. In the embodiment illustrated in Figure 15 and its modifications, the auxiliary drive unit 32 or the second electronic control circuit EC5 is configured to store the second device identifier ID2 (e.g., the fourth device identifier ID4). However, the connection point JC may be configured to store the second device identifier ID2 (e.g., the fourth device identifier ID4). In such modifications, the connection point JC includes a memory configured to store the second device identifier ID2 (e.g., the fourth device identifier ID4). Such a memory may have substantially the same structure as the memory EC52 of the second electronic control circuit EC5.The electronic control circuit EC1 of the human-powered vehicle component BC1 may be configured to determine a device electrically connected to the human-powered vehicle component BC1 based on the second device identifier ID2 (e.g., the fourth device identifier ID4) stored in the memory of the connection point JC. For example, the human-powered vehicle component BC1 is configured to receive the second device identifier ID2 (e.g., the fourth device identifier ID4) via the second electrical cable CB21 when the human-powered vehicle component BC1 is powered on.

[0341] In order to prevent the over-discharge of an energy source that supplies the gear changer 12 with electrical energy, the gear changer 12 is, as shown in the Fig. 37 and Fig. 38, is designed not to carry out the gear change immediately after the previous gear change if the remaining level of the energy source is below a predetermined level. Fig. 37 shows a case where at least two control signals CS11 or CS12 are transmitted in response to multiple pressing of the key. Fig.38 shows a case where at least two control signals CS11 or CS12 are transmitted in response to a long button press. For example, the gear changer 12 is configured not to execute the gear change when the remaining level of the electric power source is lower than a predetermined level, when the gear changer 12 receives a control signal indicating the next gear change, and when a predetermined time has not yet elapsed since the completion of the previous gear change. The gear changer 12 is configured to execute a gear change when the remaining level of the electric power source is lower than a predetermined level, when the gear changer 12 receives a control signal indicating the next gear change, and when the predetermined time has elapsed since the completion of the previous gear change.The calculation of the remaining level of the electric power source is performed at the time the previous gear shift is completed. For example, the above-mentioned actions of the gear shifter 12 can only be performed in a gear shift restriction mode. The user can select the gear shift restriction mode or another mode using an electronic device such as a smartphone, tablet computer, PC, bicycle computer, or wearable device.
