Description

Technical Field

[0001] The present disclosure generally relates to a bicycle component for a bicycle. More specifically, the present disclosure relates to a bicycle component that provides information related to an abnormal state of a bicycle component or an additional bicycle component connected to the bicycle component. Background Art

[0002] Recently, bicycles include various electric bicycle components to make the bicycles easier to operate. For example, an electric shifting system that has been provided includes an electric front derailleur, an electric rear derailleur, and an electric shift operating device. If one of these electric bicycle components malfunctions or operates abnormally, the user generally needs to take the bicycle to a bicycle shop for repair. Therefore, some bicycle manufacturers have developed diagnostic devices that can be connected to the electric bicycle components for diagnosing a fault or problem of the electric bicycle components. An example of such a diagnostic device is disclosed in U.S. Patent No. 9,227,697 assigned to Shimano Inc. Summary of the Invention

[0060] Selected embodiments will now be explained with reference to the accompanying drawings. It will be apparent to those skilled in the art of bicycles that the following description of the embodiments is for illustration only and not for limiting the present invention as defined by the appended claims and their equivalents.

[0061] First, referring to Figure 1 , a bicycle B with a bicycle control system 10 according to the illustrated embodiment is shown. Here, the bicycle B is illustrated as an electric bicycle that is propelled using the driving force of an electric motor in addition to the driving force of a person. However, the bicycle control system 10 can be applied to any other type of bicycle, such as a mountain bike, cross - country bike, gravel bike, city bike, cargo bike, and recumbent bike. Furthermore, it will be apparent from the present disclosure that the bicycle B can have bicycle components different from those Figure 1 shown in the illustrated bicycle components.

[0062] Referring to Figure 1 and Figure 2, for example, the bicycle control system 10 may include one or more of the following bicycle components BC: a derailleur 12, a remote control unit 14, a shift operating device 16, a drive unit 18, a front suspension 20, a rear suspension 22, a suspension operating device 24, an adjustable seat post 26, a seat post operating device 28, a hub dynamo 30, and a bicycle computer 32. Of course, it will be apparent from the present disclosure that some of the bicycle components BC may be omitted from the bicycle control system 10 as needed and / or desired, and the bicycle control system 10 may include other bicycle components. In the illustrated embodiment, for example, the derailleur 12 is a rear derailleur. However, the derailleur 12 may include a front derailleur or an internal gear hub. Additionally, for example, as needed and / or desired, the shift operating device 16, the suspension operating device 24, and the seat post operating device 28 may be replaced by a single operating device configured to perform all of their functions. Further, as needed and / or desired, the suspension operating device 24 may be replaced by a front suspension operating device and a rear suspension operating device.

[0063] As Figure 1 shown, the bicycle B further includes a power supply device 34. Here, the power supply device 34 is a battery pack including one or more batteries. Here, for example, the power supply device 34 is located in the down tube of the bicycle frame. Alternatively, the power supply device 34 may be attached to the outer surface of the bicycle frame, or disposed in the adjustable seat post 26 of the seat tube of the bicycle frame. The power supply device 34 preferably includes one or more rechargeable batteries. The power supply device 34 is configured to supply power to the drive unit 18. For example, as Figure 1 shown, the drive unit 18 is electrically connected to the power supply device 34 via a cable 36. Optionally, the power supply device 34 may be configured to supply power to the rear derailleur 12. For example, as Figure 2 shown by the dashed line in, the rear derailleur 12 may be electrically connected to the electrical contact of the drive unit 18 such that the rear derailleur 12 receives power from the power supply device 34 via the drive unit 18. Alternatively, the rear derailleur 12 may be directly connected to the power supply device 34 to directly receive power from the power supply device 34.

[0064] Here, each of the bicycle components 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, and 32 is an e-bicycle component, which includes a controller for controlling the bicycle component and a communicator for communicating signals with at least one other bicycle component. As used herein, the terms "controller" and "electronic controller" refer to hardware that executes a software program and do not include humans. As used herein, the term "communicator" refers to hardware that transmits signals and does not include humans. The term "communicator" includes a receiver, a transmitter, a transceiver, a transmitter-receiver, and any individual or combined device or devices contemplated to be capable of transmitting and / or receiving communication signals, including shift signals or control, command, or other signals related to some function of the component being controlled.

[0065] Reference Figure 3 , Figure 4 and Figure 7 , an example of a bicycle control system 10 will be described, where the bicycle control system 10 includes a bicycle component BC and a communication device CD. In the illustrated embodiment, the bicycle control system 10 includes a rear derailleur 12 (a shifting device) as the bicycle component BC. Additionally, among the bicycle components BC, a smartphone is included as the communication device CD. However, the bicycle control system 10 is not limited to the illustrated embodiment. Specifically, in the bicycle control system 10, the bicycle component BC includes at least one of an operation device (e.g., a shift operation device 16, a suspension operation device 24, and / or a seat post operation device 28), a hub dynamo (e.g., a hub dynamo 30), a shifting device (e.g., a rear derailleur 12), an adjustable seat post (e.g., an adjustable seat post 26), a suspension (e.g., a front suspension 20 and / or a rear suspension 22), a bicycle computer (e.g., a bicycle computer 32), and an auxiliary drive unit (e.g., a drive unit 18). Generally, the drive unit 18 and the hub dynamo 30 are not provided together on the bicycle B. For example, in a case where the drive unit 18 is provided and the rear derailleur 12 receives power from a power supply device 34 via the drive unit 18, the hub dynamo 30 can be omitted. Alternatively, in a case where the hub dynamo 30 supplies power to the rear derailleur 12, the drive unit 18 can be omitted.

[0066] Furthermore, the communication device CD is not limited to the smartphone (i.e., an external device) in the illustrated embodiment. The communication device CD can include at least one of a tablet computer, a laptop computer, a watch-type portable information terminal, a personal computer, and any other portable electronic device having a communication function. Additionally, the communication device CD can include a bicycle component, and the bicycle component includes a communicator such as a bicycle computer or a control unit mounted to the bicycle B.

[0067] Further, as Figure 3 ,Figure 4 and Figure 7 As shown, an illustrated embodiment of a bicycle control system 10 will be described, where the bicycle control system 10 includes a hub generator 30 as an additional bicycle component BC'. Here, the additional bicycle component BC' (30) is electrically connected to the bicycle component BC (12) via a cable 38. Since the additional bicycle component BC' is a hub generator, the additional bicycle component BC' (30) is configured to generate electric power supplied to the rear derailleur 12. However, the additional bicycle component BC' is not limited to the hub generator 30 in the illustrated embodiment. Specifically, in the bicycle control system 10, the additional bicycle component BC' includes at least one of an operating device (e.g., a shift operating device 16, a suspension operating device 24, and / or a seat post operating device 28), a hub generator (e.g., the hub generator 30), a speed change device (e.g., the rear derailleur 12), an adjustable seat post (e.g., the adjustable seat post 26), a suspension (e.g., a front suspension 20 and / or a rear suspension 22), a bicycle computer (e.g., the bicycle computer 32), and an auxiliary drive unit (e.g., the drive unit 18).

[0068] Referring Figures 3 to 6 , the basic mechanical structure of the bicycle component BC (the rear derailleur 12) of the bicycle control system 10 will be described for understanding the illustrated embodiment. Although the bicycle component BC is a rear derailleur (i.e., a speed change device), the bicycle component BC can be a different type of bicycle component as needed and / or desired. Here, as Figure 3 and Figure 4 shown, the bicycle component BC (12) includes a base member 40, a movable member 42, and a link structure 44. The base member 40 is configured to be mounted to the bicycle B. For example, here, the base member 40 is detachably mounted to the rear frame body RB in a conventional manner such as a fixing bolt 46. The movable member 42 is configured to be movable relative to the base member 40. The link structure 44 connects the base member 40 to the movable member 42. Specifically, the link structure 44 is configured to movably connect the movable member 42 relative to the base member 40. Here, in the illustrated embodiment, the link structure 44 includes an outer link member 44A and an inner link member 44B. A first end of the outer link member 44A is pivotally coupled to the base member 40. Similarly, a first end of the inner link member 44B is pivotally coupled to the base member 40. A second end of the outer link member 44A is pivotally coupled to the movable member 42. Similarly, a second end of the inner link member 44B is pivotally coupled to the movable member 42. Thus, the base member 40, the movable member 42, the outer link member 44A, and the inner link member 44B form a four-bar linkage mechanism.

[0069] Here, when the bicycle component BC is a derailleur, the bicycle component BC (12) further includes a chain guide 48. The chain guide 48 is configured to be pivotally coupled to the movable member 42 about a pivot axis P1. The chain guide 48 is configured to move a chain CN ( Figure 1 ) between a plurality of sprockets SP ( Figure 1 ) of a sprocket assembly for changing a shift (gear) position. The chain guide 48 is configured to contact the chain CN when the movable member 42 moves relative to the base member 40 in the lateral direction of the bicycle B, so as to shift the chain CN between the rear sprockets SP. Preferably, the chain guide 48 substantially includes a pair of chain holding plates 50, a guide pulley 52, and a tension pulley 54. The guide pulley 52 and the tension pulley 54 are rotatably disposed between the chain holding plates 50. Since the rear derailleur is well known in the bicycle field, only the conventional structure of the bicycle component BC (12) will be discussed to the extent necessary for understanding the bicycle control system 10.

[0070] As Figures 3 to 5 shown, the bicycle component BC (12) further includes an actuator unit 56. The actuator unit 56 is configured to move the movable member 42 relative to the base member 40 in response to a shift command as explained below. The actuator unit 56 is provided to one of the base member 40, the movable member 42, and the link structure 44. In the illustrated embodiment, the actuator unit 56 is provided to the base member 40. However, as needed and / or desired, the actuator unit 56 may be provided to the movable member 42 or the link structure 44.

[0071] As Figure 7 shown, the actuator unit 56 includes an actuator 58. The actuator 58 is operatively coupled to the link structure 44. Specifically, the actuator 58 is operatively coupled to the link structure 44 to move the movable member 42 relative to the base member 40 in response to a shift command. Here, when the bicycle component BC (12) is mounted on the bicycle B, the actuator 58 is controlled in response to an input by the user to the shift operation device 16 in the manual shift mode or a shift signal generated by the remote control unit 14 in the automatic shift mode. In the illustrated embodiment, the actuator 58 is an electric motor. Preferably, the actuator 58 is a reversible electric motor. Thus, in the illustrated embodiment, the bicycle component BC (12A) constitutes an electric rear derailleur. As Figures 3 to 7 shown, the actuator unit 56 includes a housing 60. The housing 60 houses the actuator 58. Here, the housing 60 is provided at the base member 40. Alternatively, as needed and / or desired, the housing 60 may be provided to the movable member 42 or the link structure 44.

[0072] Referring to Figure 3 , Figure 5 and Figure 6, the bicycle component BC (rear derailleur 12) further includes a reinforcing member 62. The reinforcing member 62 is coupled to the bottom surface of the outer link 44A. Preferably, the reinforcing member 62 is detachably coupled to the bottom surface of the outer link 44A by a pair of screws 64. The reinforcing member 62 is configured to cover the bottom end of the pivot pin 66 that connects the outer link 44A to the base member 40. The reinforcing member 62 is also configured to cover the bottom end of the pivot pin 68 that connects the outer link 44A to the movable member 42.

[0073] Now refer to Figure 7 , a schematic block diagram of the electrical configuration of the bicycle control system 10 of the illustrated embodiment will now be described, where the bicycle control system 10 includes a bicycle component BC, an additional bicycle component BC', and a communication device CD. In Figure 7 the illustrated embodiment, the bicycle control system 10 includes a rear derailleur 12 (shift device) as the bicycle component BC, a hub dynamo 30 as the additional bicycle component BC', and a smartphone as the communication device CD. However, as described above, the bicycle control system 10 is not limited to the illustrated embodiment. In other words, depending on the needs and / or desires, the following description of the electrical configuration of the bicycle control system 10 can be applied to other combinations of bicycle components.

[0074] As Figure 7 shown, the bicycle component BC (12) includes a controller 70 and a communicator 72. The controller 70 is configured to send command signals, data signals, or other information to the communicator 72, and is configured to receive data signals or other information from the communicator 72. Preferably, the controller 70 and the communicator 72 are disposed on a circuit board. Thus, the communicator 72 is electrically connected to the controller 70. Accordingly, the controller 70 is configured to control the actuator 58 and the communicator 72 and / or communicate with the actuator 58 and the communicator 72. Preferably, the controller 70 and the communicator 72 are disposed in the housing 60 of the actuator unit 56 together with the actuator 58.

[0075] The controller 70 is configured to be electrically connected to the actuator unit 56. Preferably, the controller 70 is electrically connected to the actuator 58. Thus, the actuator unit 56 is configured to be electrically connected to the controller 70. The controller 70 is configured to actuate the actuator unit 56. An actuator (motor) driver 73 is provided for driving the actuator 58. The actuator driver 73 is electrically connected to the controller 70. Here, the actuator driver 73 is a drive circuit provided on a circuit board, and the actuator driver 73 includes an inverter circuit. The actuator driver 73 drives the actuator 58 in accordance with a control signal from the controller 70. Preferably, the controller 70 and the actuator driver 73 are provided in the housing 60 of the actuator unit 56. Although in the illustrated embodiment, the controller 70 and the actuator driver 73 are preferably provided on the same circuit board, the controller 70 and the actuator driver 73 may be provided on separate circuit boards as needed and / or desired. Thus, the controller 70 is configured to control and / or communicate with the actuator 58.

[0076] In addition, the bicycle component BC(12) further includes a sensor 74. The controller 70 is configured to obtain information related to an abnormal state of the bicycle component BC(12) based on an output from the sensor 74. A communicator 72 is configured to send the information to a communication device CD. Thus, the user can be notified of the abnormal state of the bicycle component BC(12). The abnormal state may occur when an obstacle directly contacts the bicycle component BC(12). The abnormal state includes a state where the bicycle B is in a normal operation state and a state where the bicycle is in an abnormal operation state. Generally, the term "abnormal state" refers to any state where the bicycle component BC is not being normally operated. For example, normal operation states include expected states such as a low battery state, a weak communication signal, the battery being connected in a normal manner, the cable being connected in a normal manner, etc. However, the term "abnormal state" also refers to a state where the bicycle B is in a normal operation state, but some abnormal event has occurred, such as an obstacle directly contacting the bicycle component BC(12). In other words, for example, in the case where an obstacle directly contacts the bicycle component BC(12), the controller 70 may be configured to determine that the output from the sensor 74 meets a predetermined criterion for establishing the existence of an abnormal state, even though the bicycle component BC(12) appears to be operating normally in other respects. Thus, an abnormal state may exist even if an input to the bicycle B from an obstacle (including but not limited to a direct input to the bicycle component BC(12)) does not cause any abnormal operation of the bicycle B.

[0077] As will be explained later, although the sensor 74 is provided to the bicycle component BC(12) for detecting whether an abnormal state exists, the sensor 74 is not limited to this position. For example, a sensor for detecting whether an abnormal state of the bicycle component BC exists may be provided on an additional bicycle component BC'(30). Additionally, for example, a sensor for detecting whether an abnormal state of the bicycle component BC exists may be provided at some other positions on the bicycle that are separated from both the bicycle component BC(12) and the additional bicycle component BC'(30).

[0078] Basically, the controller 70 is an electronic controller including at least one processor 70A configured to execute a predetermined control program (e.g., an obstacle detection program, a fault detection program, a setting program, a shifting program, etc.). In the case of the fault detection program, a fault of the controller of the bicycle component BC(12) or the additional bicycle component BC'(30) can be based on the performance of the bicycle component BC(12) or the additional bicycle component BC'(30). For example, when a fault occurs in the controller 70 of the bicycle component BC(12), the shifting performance may become low. For example, the processor 70A includes a central processing unit (CPU) or a microprocessing unit (MPU). When the bicycle component BC(12) is mounted to the bicycle B, the controller 70 is electrically connected to the additional bicycle component BC'(30) for receiving power therefrom. Alternatively, the bicycle component BC(12) may be provided with its own power source, or may be electrically connected to the power supply device 34.

[0079] The controller 70 is configured to control the actuator 58 to move the chain guide 48 so as to shift the chain CN between the rear sprockets SP in a conventional manner. The actuator 58 can be controlled by a control signal from the remote control unit 14 or the shift operation device 16. The remote control unit 14 can also be used to adjust the settings of the bicycle component BC(12), and to manually actuate the actuator 58 to perform a shifting operation. On the other hand, the shift operation device 16 can be used to manually actuate the actuator 58 to perform a shifting operation.

[0080] The bicycle component BC(12) further includes a storage device 76. Herein, for example, the storage device 76 includes at least one of, for example, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), and a flash memory. The storage device 76 stores various control processes or control programs, as well as information or data used by the controller 70. Accordingly, the storage device 76 is electrically connected to the controller 70. In this way, the controller 70 can retrieve the data stored in the storage device 76 and access the programs stored in the storage device 76, and can store data into the storage device 76. The storage device 76 is configured to store various control programs (e.g., a shifting program), operation data, etc. Specifically, the controller 70 is configured to obtain information related to an abnormal state of the bicycle component BC(12) based on the output from the sensor 74. The controller 70 is configured to store the information related to the abnormal state in the storage device 76. In this way, the storage device 76 is configured to store information.

[0081] Herein, the communicator 72 includes a wireless communication circuit 78. The wireless communication circuit 78 may be provided on the same circuit board as the controller 70, or may be provided on a separate circuit board as needed and / or desired. Accordingly, the controller 70 is electrically connected to the wireless communication circuit 78. Using the wireless communication circuit 78, the bicycle component BC(12) can wirelessly communicate with an additional bicycle component BC'(30) and the communication device CD. In addition, using the wireless communication circuit 78, the bicycle component BC(12) can wirelessly communicate with the remote control unit 14 and / or the shifting operation device 16. In the illustrated embodiment, the communicator 72 is configured to receive information related to an abnormal state from the controller 70. Then, the communicator 72 is configured to wirelessly transmit the information related to the abnormal state to the communication device CD.

[0082] Herein, the wireless communication circuit 78 is configured to receive and transmit wireless communication signals. Specifically, the wireless communication circuit 78 includes a signal transmitting circuit 78A (TX circuit) and a signal receiving circuit 78B (RX circuit). The signal transmitting circuit 78A may also be referred to as a wireless transmitter. The signal receiving circuit 78B may also be referred to as a wireless receiver. The wireless communication signal may be a radio frequency (RF) signal, an ultra-wideband communication signal, radio frequency identification (RFID), ANT+ communication or communication, BLE communication (a primitive wireless communication standard), or any other type of signal understood in the bicycle field applicable to short-distance wireless communication.

[0083] In addition, optionally, the bicycle component BC(12) further includes a wired communication circuit 80. The wired communication circuit 80 may be provided on the same circuit board as the controller 70, or may be provided on a separate circuit board as needed and / or desired. In this way, the controller 70 is electrically connected to the wired communication circuit 80. Alternatively, if needed and / or desired, the wired communication circuit 80 may be omitted. Using the wired communication circuit 80, the bicycle component BC(12) can communicate with an additional bicycle component BC'(30) via a cable 38 using power line communication (PLC). Accordingly, the controller 70 is configured to receive a data signal from the communicator 72 and output a data signal to the communicator 72.

[0084] Here, the wired communication circuit 80 is configured to receive and transmit communication signals. Specifically, the wired communication circuit 80 includes a power line communication circuit 80A configured to perform two-way wired communication via the cable 38. Alternatively, if needed and / or desired, the wired communication circuit 80 may be omitted.

[0085] The bicycle component BC(12) further includes an antenna 82 coupled to the communicator 72. The antenna 82 is configured to receive and transmit wireless signals from the communicator 72. Here, the bicycle component BC(12) further includes a signal amplifier 84 coupled to the communicator 72. The signal amplifier 84 is provided for selectively amplifying the signals of the antenna 82. The signal amplifier 84 may be controlled by the controller 70 or a slave controller of the communicator 72.

[0086] In the illustrated embodiment, the bicycle component BC(12) is illustrated as having only a single controller (i.e., the controller 70) and a single storage device (i.e., the storage device 76). However, as needed and / or desired, the communicator 72 may have its own controller and its own storage device. For example, the controller 70 may be a master controller, and the controller of the communicator 72 may be a slave controller. Accordingly, the term "controller" as used herein includes a single controller or multiple controllers located at separate positions. Similarly, the term "storage device" as used herein includes a single storage device or multiple storage devices located at separate positions.

[0087] The controller 70 can be configured to control the communicator 72 to send information related to the abnormal state to the communication device CD in different ways. For example, the communicator 72 is configured to send information to the communication device CD each time the controller 70 obtains information. In this way, each time the controller 70 determines that an abnormal state exists based on the output from the sensor 74, the communicator 72 sends information related to the current abnormal state to the communication device CD. Preferably, each time an abnormal state is detected, the controller 70 stores the information based on the output from the sensor 74 in the storage device 76. In this way, a log of information on all abnormal states detected within a predetermined period is created. The predetermined period can be, for example, a preset time period, a period starting each time power is supplied to the bicycle component BC, or a period lasting until the user manually resets (clears) the information log.

[0088] Instead of merely sending information related to the current abnormal state to the communication device CD each time an abnormal state exists, for example, the controller 70 can be configured to control the communicator 72 to send information related to multiple abnormal state occurrences at different times to the communication device CD in a single communication. In other words, the information includes first information obtained at a first time and second information obtained at a second time. The second time is different from the first time. Then, the communicator 72 is configured to send the first information and the second information together to the communication device CD. Of course, the information can include additional information (such as third information, fourth information, etc.) obtained at different times (such as a third time, a fourth time, etc.), and these information are sent together in a single communication.

[0089] The sensor 74 is configured to detect an input to the bicycle component BC(12) from an obstacle. The terms "sensor" and "detector" as used herein refer to a hardware device or instrument designed to detect the presence or absence of a specific event, object, substance, or a change in its environment and emit a response signal. The terms "sensor" and "detector" as used herein do not include humans. The controller 70 is constructed to be electrically connected to the sensor 74. Therefore, the controller 70 is configured to receive the output (i.e., the detection result) from the sensor 74. The controller 70 is configured to obtain information related to the abnormal state of the bicycle component BC(12) based on the output from the sensor 74.

[0090] The controller 70 is configured to output the information as a data signal to the communicator 72 based on the detection result from the sensor 74. Alternatively, in the case where the communicator 72 includes a controller, the sensor 74 can be configured to directly send the detection result to the communicator 72. In any case, the communicator 72 is configured to send information to the communication device CD. The communicator 72 can wirelessly send information to the communication device CD using the wireless communication circuit 78. Alternatively, the communicator 72 can send information to the communication device CD using the wired communication circuit 80.

[0091] Preferably, the sensor 74 includes an acceleration sensor configured to detect the acceleration input to the bicycle component BC(12). The sensor 74 is provided to at least one of the base member 40, the movable member 42, and the link structure 44. The housing 60 houses the sensor 74.

[0092] The controller 70 is configured to evaluate information to determine whether to send information to the communication device CD. For example, in the case where an obstacle contacts the bicycle component BC(12), the controller 70 compares the detection result from the sensor 74 with a threshold value pre-stored in the storage device 76. The controller 70 is configured to send information when the information indicates that the output from the sensor 74 is greater than the threshold value. Thus, before sending information to the communication device CD, the information to be sent to the communication device CD can be appropriately filtered by the controller 70.

[0093] Now referring to Figure 7 , the electrical configuration of the additional bicycle component BC'(30) will be discussed. Although the additional bicycle component BC'(30) is a hub dynamo, the additional bicycle component BC'(30) may be a different type of bicycle component as needed and / or desired. Thus, the additional bicycle component BC' is not limited to the hub dynamo 30 of the illustrated embodiment. Since the mechanical structure of a hub dynamo such as the hub dynamo 30 is well known in the bicycle field, the mechanical structure of the hub dynamo 30 will not be further described.

[0094] Here, the additional bicycle component BC'(30) includes an additional controller 86, an additional communicator 88, and a storage device 90. Here, the additional bicycle component BC'(30) further includes an additional sensor 92. The additional controller 86 is configured to send a command signal, a data signal, or other information to the additional communicator 88, and is configured to receive a data signal or other information from the additional communicator 88. Preferably, the additional controller 86 and the additional communicator 88 are provided on a circuit board. Thus, the additional communicator 88 is electrically connected to the additional controller 86. Accordingly, the additional controller 86 is configured to control and / or communicate with the additional communicator 88. In the case of a hub dynamo, the additional controller 86 and the additional communicator 88 are provided in the hub shell of the additional bicycle component BC'(30).

[0095] Basically, the additional controller 86 is an electronic controller including at least one processor 86A configured to execute a predetermined control program (e.g., an obstacle detection program, a fault detection program, a setting program, a generation control program, etc.). The processor 86A includes, for example, a central processing unit (CPU) or a microprocessing unit (MPU). When the additional bicycle component BC'(30) is mounted to the bicycle B, the additional controller 86 controls the power supplied to the bicycle component BC(12) via the cable 38.

[0096] Here, the additional communicator 88 includes a wireless communication circuit 96. Optionally, in order to enhance the signal of the wireless communication circuit 96, as needed and / or desired, the additional bicycle component BC'(30) may also include an antenna and a signal amplifier. Alternatively, if needed and / or desired, the wireless communication circuit 96 may be omitted, and wired communication may be performed between the bicycle component BC(12) and the additional bicycle component BC'(30) via the cable 38, as discussed below. The wireless communication circuit 96 may be provided on the same circuit board as the additional controller 86, or, as needed and / or desired, on a separate circuit board. In this way, the additional controller 86 is electrically connected to the wireless communication circuit 96. Using the wireless communication circuit 96, the additional bicycle component BC'(30) can communicate wirelessly with the bicycle component BC(12). In the illustrated embodiment, the additional communicator 88 is configured to receive information related to an abnormal state from the additional controller 86 and transmit it to the communicator 72 of the bicycle component BC(12).

[0097] Here, the wireless communication circuit 96 is configured to receive and transmit wireless communication signals. Specifically, the wireless communication circuit 96 includes a signal transmission circuit 96A (TX circuit) and a signal reception circuit 96B (RX circuit). The signal transmission circuit 96A may also be referred to as a wireless transmitter. The signal reception circuit 96B may also be referred to as a wireless receiver. The wireless communication signal may be a radio frequency (RF) signal, an ultra-wideband communication signal, radio frequency identification (RFID), ANT+ communication or communication, BLE communication (a primitive wireless communication standard) or any other type of signal understood in the bicycle field applicable to short-distance wireless communication.

[0098] In addition, optionally, the additional bicycle component BC'(30) further includes a wired communication circuit 98. The wired communication circuit 98 may be disposed on the same circuit board as the additional controller 86, or may be disposed on a separate circuit board as needed and / or desired. In this way, the additional controller 86 is electrically connected to the wired communication circuit 98. Alternatively, if needed and / or desired, the wired communication circuit 98 may be omitted. Using the wired communication circuit 98, the additional bicycle component BC'(30) can communicate with the bicycle component BC(12) via the cable 38 using power line communication (PLC). Therefore, the additional controller 86 is configured to receive a data signal from the additional communicator 88 and output a data signal to the additional communicator 88.

[0099] Here, the wired communication circuit 98 is configured to receive and transmit communication signals. Specifically, the wired communication circuit 80 includes a power line communication circuit 98A configured to perform two-way wired communication via the cable 38. Alternatively, if needed and / or desired, the wired communication circuit 98 may be omitted.

[0100] Here, for example, the storage device 90 includes at least one of, for example, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), and a flash memory. The storage device 90 stores various control processes or control programs and information or data used by the additional controller 86. Therefore, the storage device 90 is electrically connected to the additional controller 86. In this way, the additional controller 86 can retrieve the data stored in the storage device 90 and access the programs stored in the storage device 90, and can store data in the storage device 90. The storage device 90 is configured to store various control programs (for example, an obstacle detection program, a generator failure detection program, a battery failure detection program, etc.), operation data, etc. Specifically, the additional controller 86 is configured to obtain information related to the abnormal state of the additional bicycle component BC'(30) based on the output from the additional sensor 92. The additional controller 86 is configured to store the information related to the abnormal state in the storage device 90.

[0101] Basically, the additional sensor 92 is provided at the additional bicycle component BC'(30). However, the additional sensor 92 does not need to be located at the additional bicycle component BC'(30). For example, the additional sensor 92 can be located at a position remote from the additional bicycle component BC'(30) and the bicycle component BC(12). In other words, the additional sensor 92 can be a component separate from the bicycle component BC(12) and the additional bicycle component BC'(30). In any case, the additional sensor 92 is configured to detect an additional input from an obstacle to the bicycle B. In the case of the illustrated embodiment, the additional sensor 92 is configured to detect an additional input from an obstacle to the additional bicycle component BC'(30). Preferably, in the illustrated embodiment, the additional sensor 92 includes an additional acceleration sensor. The additional acceleration sensor is configured to detect an additional acceleration input from an obstacle to the bicycle B. In the case where the additional sensor 92 is provided to the additional bicycle component BC'(30), the additional acceleration sensor is configured to detect an additional acceleration input from an obstacle to the additional bicycle component BC'(30). However, the additional sensor is not limited to an acceleration sensor. The additional sensor 92 can be a sensor that detects other abnormal states that may occur in the additional bicycle component BC'(30). In any case, the additional sensor 92 outputs information related to the abnormal state. Therefore, the information is based on the additional output from the additional sensor 92.

[0102] In the illustrated embodiment, the additional communicator 88 does not communicate directly with the communication device CD. Instead, in the illustrated embodiment, the additional communicator 88 communicates with the communicator 72 of the bicycle component BC(12). Therefore, the information related to the abnormal state is output from the additional sensor 92 to the additional controller 86. Then, the additional controller 86 controls the additional communicator 88 to send the information to the communicator 72 of the bicycle component BC(12). Therefore, the controller 70 receives the information based on the additional output from the additional sensor 92 via the additional communicator 88. The information based on the additional output from the additional sensor 92 can be sent via wired communication or wireless communication. In this way, the controller 70 is configured to obtain information based on the signal received from the additional controller 86 of the additional bicycle component BC'(30). Therefore, the controller 70 is configured to obtain information related to the abnormal state of the additional bicycle component BC'(30) connected to the bicycle component BC(12).

[0103] The controller 70 is configured to evaluate information to determine whether to send information to the communication device CD. For example, in the case where an obstacle contacts the additional bicycle component BC'(30), the controller 70 compares the detection result from the additional sensor 92 with a threshold value pre-stored in the storage device 76. The controller 70 is configured to send information when the information indicates that the additional output from the additional sensor 92 is greater than the threshold value. In this way, before sending information to the communication device CD, the information to be sent to the communication device CD can be appropriately filtered by the controller 70.

[0104] In the illustrated embodiment, the bicycle control system 10 includes both the sensor 74 and the additional sensor 92. However, according to needs and / or expectations, the bicycle control system 10 can be configured to include only the sensor 74 or only the additional sensor 92. Further, although the sensor 74 and the additional sensor 92 are described as including an acceleration sensor and an additional acceleration sensor respectively, the bicycle control system 10 is not limited to using acceleration sensors. Depending on the bicycle component, the bicycle control system 10 can include other types of sensors. For example, the bicycle component BC(12) can be provided with a sensor for detecting an abnormal state of the communicator 72. Similarly, the additional bicycle component BC'(30) can be provided with a sensor for detecting an abnormal state of the additional communicator 88.

[0105] Since the additional bicycle component BC'(30) is a hub dynamo, the additional bicycle component BC'(30) further includes an electrical unit 94. The electrical unit 94 includes a generator and a battery. The generator is configured to generate electricity when the rear wheel rotates. The electricity is stored in the battery of the electrical unit 94. The electrical unit 94 is electrically connected to the electrical part of the bicycle component BC(12) through a cable 38. In this way, electricity is supplied from the battery of the electrical unit 94 to the electrical part of the bicycle component BC(12).

[0106] In addition, in the case where the additional bicycle component BC'(30) is a hub dynamo, the additional sensor 92 can include a sensor for detecting an abnormal state of the battery and / or a sensor for detecting an abnormal state of the generator.

[0107] In the illustrated embodiment, the communication device CD is configured to wirelessly communicate with one or more of the bicycle components BC. Here, in the illustrated embodiment, as mentioned above, the communication device CD includes an external device. Thus, in the case where the communication device CD includes an external device, the communication device CD has one or more main functions such as a telephone function, a messaging function, a web browsing function, etc. In other words, the external device has a first function in addition to the second function related to the bicycle B. The first function of the external device (communication device CD) includes one or more main functions such as a telephone function, a messaging function, a web browsing function, etc. The second function of the external device (communication device CD) includes one or more secondary functions such as communicating with the bicycle component BC, diagnosing an error in the bicycle component BC, displaying data of the bicycle component BC, etc.

[0108] As Figure 7 shown, the communication device CD includes a controller 99A and a communicator 99B. The controller 99A includes an application program (referred to as "App") or program for processing information from the bicycle component BC (12). The communicator 99B is configured to wirelessly communicate with at least the bicycle component BC (12). Since the communication device CD is a conventional device and the details thereof are well known, the communication device CD will not be further described herein.

[0109] As Figure 7 shown, the communication device CD includes a notification device 99C. The notification device 99C is configured to output notification information related to an abnormal state. Here, the communication device CD is a smart phone including a display as an example of the notification device 99C. The display includes, for example, a liquid crystal display, a segment display, or an organic light emitting diode (OLED) display. Additionally, in the case of a smart phone, the communication device CD includes a speaker as another example of the notification device 99C. The notification information includes first operation information for prompting a user operation to be performed by the user to correct, investigate, or check the abnormal state of the bicycle component BC (12). For example, the message of the first operation information may be a message for prompting the user to check the operation of the bicycle component BC (12). The notification information further includes second operation information for prompting the user to take the bicycle component BC (12) to a dealer. Depending on the nature of the abnormal state of the bicycle component BC (12), the first operation information or the second operation information may be provided in the notification information of the abnormal state of the bicycle component BC (12), or both the first operation information and the second operation information may be provided in the notification information of the abnormal state of the bicycle component BC (12).

[0110] A non-transitory computer-readable storage medium can be provided to the communication device CD for communicating with the bicycle component BC(12) to receive information related to the abnormal state of the bicycle component BC(12) and / or the abnormal state of the additional bicycle component BC'(30). The non-transitory computer-readable storage medium provided to the communication device CD is, for example, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, an optical disk, a pluggable USB drive, etc. The non-transitory computer-readable storage medium stores a program thereon. The program can be executed by the communication device CD. In other words, the computer-readable storage medium stores a computer program therein. The computer program is for execution by a processor of the communication device CD to implement various processes for receiving information related to the abnormal state of the bicycle component BC(12) and / or the abnormal state of the additional bicycle component BC'(30).

[0111] In the case where the information sent to the communication device CD is related to the abnormal state of the bicycle component BC(12), the instructions of the program are configured to cause the communication device CD to receive information related to the abnormal state of the bicycle component BC(12) from the communicator 72 of the bicycle component BC(12), and to cause the notification device 99C to output notification information related to the abnormal state. As mentioned above, in this case, the information is obtained by the controller 70 based on the output from the sensor 74 of the bicycle component BC(12). The sensor 74 is configured to detect an input from an obstacle to the bicycle component BC(12). In other words, the abnormal state of the bicycle component BC(12) is directly sent from the communicator 72 of the bicycle component BC(12).

[0112] In the case where the information sent to the communication device CD is related to the abnormal state of the additional bicycle component BC'(30), the instructions of the program are configured to cause the communication device CD to receive information related to the abnormal state of the additional bicycle component BC'(30) from the communicator 72 of the bicycle component BC(12), and to cause the notification device 99C to output notification information related to the abnormal state. As mentioned above, in this case, the information is obtained by the controller 70 of the bicycle component BC(12). The controller 70 is configured to actuate the actuator unit 56 of the bicycle component BC(12). The additional bicycle component BC'(30) is configured to be electrically connected to the bicycle component BC(12). In other words, the abnormal state of the additional bicycle component BC'(30) is directly sent from the communicator 72 of the bicycle component BC(12), rather than directly from the additional communicator 88 of the additional bicycle component BC'(30).

[0113] Now refer to Figure 8, which illustrates a modified rear derailleur 12' (i.e., a bicycle component BC), where the rear derailleur 12' can be used for Figure 7 the bicycle control system 10. Basically, the rear derailleur 12' is the same as the rear derailleur 12, except that the rear derailleur 12' has been modified to include its own power source.

[0114] The rear derailleur 12' includes a base member 40', a movable member 42', and a linkage structure 44'. The base member 40' is configured to be mounted to the bicycle B. For example, here, the base member 40' is detachably mounted to the rear frame body RB in a conventional manner such as by fixing bolts 46'. The linkage structure 44' is configured to movably connect the movable member 42' relative to the base member 40' in the same manner as described above with respect to the rear derailleur 12. Thus, here, the linkage structure 44' includes an outer link member 44A' and an inner link member 44B' that form a four-bar linkage mechanism with the base member 40' and the movable member 42'.

[0115] The rear derailleur 12' further includes a chain guide 48'. The chain guide 48' is configured to be pivotally coupled to the movable member 42'. Preferably, the chain guide 48' substantially includes a pair of chain retaining plates 50', a guide pulley 52', and a tension pulley 54'. The guide pulley 52' and the tension pulley 54' are rotatably disposed between the chain retaining plates 50'. Since rear derailleurs are well known in the bicycle field, the conventional structure of the rear derailleur 12' will only be briefly discussed herein to the extent necessary for understanding the bicycle control system 10.

[0116] Here, the rear derailleur 12' further includes a battery holder 55'. The battery holder 55' is configured to support the battery BT. The battery holder 55' is set to the outer link member 44A'. Alternatively, the battery holder can be set to any one of the base member 40', the movable member 42', and the inner link member 44B'. The battery BT is electrically connected to the actuator unit 56' to supply power to the actuator of the actuator unit 56'.

[0117] In understanding the scope of the present invention, as used herein, the term "comprising" and its derivatives are intended to be open-ended terms that specify the presence of the recited features, elements, components, groups, wholes, and / or steps, but do not preclude the presence of other unrecited features, elements, components, groups, wholes, and / or steps. The above also applies to words with similar meanings, such as the terms "including", "having", and their derivatives. In addition, unless otherwise specified, the terms "portion", "section", "part", "member", or "element" may have a dual meaning of a single component or multiple components when used in the singular form.

[0118] As used herein, the following directional terms "towards the frame side", "away from the frame side", "forward", "backward", "front", "rear", "up", "down", "above", "below", "upward", "downward", "top", "bottom", "side", "vertical", "horizontal", "perpendicular", and "lateral", and any other similar directional terms refer to those directions of a bicycle in an upright riding position and equipped with bicycle components. Accordingly, these directional terms used to describe bicycle components should be interpreted with respect to a bicycle in an upright riding position on a horizontal surface and equipped with bicycle components. The terms "left" and "right" are used to denote "right" when referring from the right side when viewed from the rear of the bicycle, and "left" when referring from the left side when viewed from the rear of the bicycle.

[0119] The phrase "at least one of..." used in this disclosure means "one or more of" the desired selections. For one example, if the number of its selections is two, the phrase "at least one of..." used in this disclosure means "only a single selection" or "both of the two selections". For another example, if the number of its selections is equal to or more than three, the phrase "at least one of..." used in this disclosure means "only a single selection" or "any combination of two or more selections". Additionally, the term "and / or" used in this disclosure means "one or both of them". For example, the phrase "at least one of A and B" encompasses (1) A alone, (2) B alone, and (3) both A and B. The phrase "at least one of A, B, and C" includes (1) A alone, (2) B alone, (3) C alone, (4) both A and B, (5) both B and C, (6) both A and C, and (7) all of A, B, and C. In other words, in this disclosure, the phrase "at least one of A and B" does not mean "at least one A and at least one B".

[0120] Furthermore, it is understood that although the terms "first" and "second" may be used herein to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another. Thus, for example, the first component discussed above may be referred to as the second component, and vice versa, without departing from the teachings of the present invention.

[0121] As used herein, the terms "attached" or "attachment" cover the following configurations: directly securing an element to another element by directly adhering the element to the other element; indirectly securing an element to another element by adhering the element to an intermediate element, which in turn is adhered to the other element; and an element being integral with another element, i.e., one element being substantially a part of the other element. This definition also applies to words having similar meanings, such as "coupled", "connected", "joined", "mounted", "adhered", "fixed", and their derivatives. Finally, degree terms such as "substantially", "about", and "approximate" used herein mean a reasonable deviation amount of the modified term such that the end result does not vary significantly.
