The first communication line L1 may be, for example, directly connected to the battery unit 58, or may be connected to the battery unit 58 via at least one of the components 42.

[0074] The storage device 80 forms a communication network with, for example, the component 42. The storage device 80 functions as, for example, a slave in the communication network. In the communication network, the first component 66 functions as, for example, a master of the storage device 80.

[0075] The control unit 86 is configured to control the storage unit 84 to store log information received from at least one component 42 provided in the human-powered vehicle 10. The log information stored in the storage unit 84 includes, for example, sensing information acquired by the at least one component 42 from the sensor 64. The log information stored in the storage unit 84 may be, for example, all of the log information stored in each component 42, or may be predetermined information among all of the log information stored in each component 42.

[0076] The control unit 86 is configured to control the storage unit 84 to store the log information received from the second component 68. The control unit 86 may be configured to control the storage unit 84 to store the log information received from the first component 66. The control unit 86 may be configured to control the storage unit 84 to store the log information received from the first component 66 and the log information received from the second component 68.

[0077] The control unit 86 controls the storage unit 84 to store the log information in response to receiving the log information, for example. The control unit 86 is configured to store the log information received from the component 42, for example, in the nonvolatile memory of the storage unit 84. The control unit 86 may be configured to store the log information newly in the nonvolatile memory of the storage unit 84 without overwriting the previously stored log information, for example, every time the control unit 86 receives the log information from the component 42. The control unit 86 may be configured to store only a portion of the log information that differs from the previously stored log information, newly in the nonvolatile memory of the storage unit 84, for example, every time the control unit 86 receives the log information from the component 42.

[0078] The control unit 86 maintains the log information stored in the memory unit 84, for example, until a predetermined condition is satisfied. The predetermined condition includes, for example, a case where the control unit 86 receives a command to delete the log information from an external device. The predetermined condition includes, for example, a case where the data capacity of the log information stored in the memory unit 84 becomes equal to or greater than a predetermined capacity. When the data capacity of the log information stored in the memory unit 84 becomes equal to or greater than a predetermined capacity, the control unit 86 may delete at least a portion of the log information in the memory unit 84, and then store the received log information in the memory unit 84.

[0079] The control unit 66A of the first component 66 is configured to, for example, control the at least one component 42 so that the at least one component 42 transmits log information to the storage device 80 when a start condition is met.

[0080] The control unit 86 is configured to control the at least one component 42 based on, for example, an operation of the at least one component 42 provided in the human-powered vehicle 10 so that the at least one component 42 transmits log information to the storage device 80. The start condition is satisfied, for example, by operating an operation unit included in the at least one component 42. The start condition is satisfied, for example, by operating the operation unit 66D of the first component 66. The start condition may also be satisfied by operating an operation unit included in the second component 68, or an operation unit included in a component 70 separate from the component 42 connected to the control system 40.

[0081] The control unit 86 may be configured to control the at least one component 42 so that the at least one component 42 transmits log information to the storage device 80 based on the receipt of the command to acquire log information. The command to acquire log information is transmitted from the at least one component 42, for example, by power being supplied to the at least one component 42. A case in which power is supplied to the at least one component 42 is, for example, a case in which power is supplied from the battery 40A to the at least one component 42. The start condition is satisfied, for example, when the control unit 86 receives the command to acquire log information.

[0082] The start condition may be satisfied when the capacity of the log information stored in at least one component 42 becomes equal to or greater than the start capacity. The start condition may be satisfied every time a predetermined set period elapses. When the start condition is satisfied every time a predetermined set period elapses, the storage device 80 collects log information every predetermined set period.

[0083] 4, a process in which the storage device 80 collects log information in the control system 40 will be described. Collection of log information by the storage device 80 is started, for example, when the above-mentioned start condition is satisfied. When the start condition is satisfied, the control unit 66A of the first component 66 sets a request to transmit the log information.

[0084] In step S11, the control unit 66A of the first component 66 sets a request to transmit log information, and the process proceeds to step S12. In step S12, the control unit 66A of the first component 66 transmits a command to transmit log information. In step S12, the control unit 66A of the first component 66 transmits a command to transmit log information to, for example, all second components 68 communicatively connected to the first component 66. In step S12, the control unit 66A of the first component 66 sequentially transmits a command to transmit log information to, for example, a plurality of second components 68 communicatively connected to the first component 66. In step S12, the control unit 66A of the first component 66 may transmit a command to transmit log information to some of the plurality of second components 68 communicatively connected to the first component 66.

[0085] In step S13, when the control unit 66A of the second component 68 receives a command to transmit log information, the process proceeds to step S14. In step S14, the control unit 66A of the second component 68 transmits the log information. In step S13, the control unit 66A of the second component 68 transmits the log information, for example, without specifying a transmission target. The transmission target is specified, for example, by identification information. When the control unit 66A of the second component 68 transmits log information without specifying a transmission target, for example, the control unit 66A of the second component 68 transmits log information in which identification information of the transmission target is not set.

[0086] The log information transmitted without specifying a transmission target is transmitted to all of the first component 66, the other second components 68, and the storage device 80 included in the communication network. The storage device 80 is configured to be able to acquire the log information transmitted without specifying a transmission target. The first component 66 is configured to be able to acquire the information transmitted from the second component 68 without specifying a transmission target, but the first component 66 may be configured to ignore the log information transmitted without specifying a transmission target without acquiring it. The second component 68 is configured, for example, to be unable to acquire the information transmitted from the other second components 68 without specifying a transmission target.

[0087] In step S15, when the control unit 86 of the storage device 80 receives the log information, the process proceeds to step S16. In step S16, the control unit 86 of the storage device 80 stores the received log information in the storage unit 84. In step S16, when log information is transmitted from multiple second components 68, the control unit 86 of the storage device 80 stores the log information for each second component 68, for example.

[0088] The control unit 66A of the first component 66 may be configured to, when setting a request to transmit log information, transmit the log information stored in its own storage unit 66B to the storage device 80. When the storage device 80 receives the log information from the first component 66, it stores the log information transmitted from the first component 66 in the storage unit 84.

[0089] The storage device 80 further includes a second communication unit 90 configured to communicate, for example, with a component 70 separate from the storage device 80, at least one of wired and wirelessly. The control unit 86 is configured, for example, to control the second communication unit 90 to transmit the log information stored in the storage unit 84 to the component 70 separate from the storage device 80. The second communication unit 90 is configured to communicate, for example, with the component 70 separate from the storage device 80, at least one of wired and wirelessly.

[0090] The storage device 80 may be configured to control the second communication unit 90 to transmit log information to a component 70 separate from the storage device 80 via a component 42 provided in the human-powered vehicle 10. The storage device 80 may transmit the log information stored in the storage unit 84 to the first component 66 by, for example, power line communication (PLC), and the first component 66 may transmit the log information received from the storage device 80 to the separate component 70 by, for example, wireless communication.

[0091] The separate component 70 is, for example, an external device, which may include, for example, at least one of a personal computer, a tablet computer, and a smartphone.

[0092] The separate component 70 includes, for example, a control unit 70A. The control unit 70A includes, for example, a processor that executes programs for carrying out various controls. The processor includes, for example, a CPU or an MPU. The control unit 70A may include one or more microcomputers. The control unit 70A may include multiple processors that are arranged separately at multiple locations.

[0093] The separate component 70 further includes, for example, a storage unit 70B. The storage unit 70B stores, for example, programs for executing various controls and information used in the control processes. The storage unit 70B includes, for example, at least one of a nonvolatile memory and a volatile memory. The nonvolatile memory includes, for example, at least one of a ROM, an EPROM, an EEPROM, and a flash memory. The volatile memory includes, for example, a RAM.

[0094] The storage unit 70B is configured to store identification information. The identification information is, for example, information that enables the storage device 80 to grasp the type of the separate component 70. The identification information is stored in the storage unit 70B, for example, at the time of shipping the separate component 70. The storage unit 70B is configured to store log information of the component 42.

[0095] The separate component 70 further includes, for example, a communication unit 70C. The separate component 70 is configured to be connectable to the storage device 80 via at least one of an electrical communication cable and a wireless communication device. The communication unit 70C may be configured to communicate with the storage device 80 via the first component 66.

[0096] A process in which the control unit 86 of the storage device 80 transmits log information to the separate component 70 will be described with reference to Fig. 5. For example, when power is supplied to the control unit 86, the control unit 86 starts the process and proceeds to step S21 of the flowchart shown in Fig. 5. When the flowchart in Fig. 5 ends, the control unit 86 repeats the process from step S21 after a predetermined period has elapsed, for example, until the supply of power is stopped.

[0097] In step S21, the control unit 86 determines whether or not there is a request to transmit log information to the separate component 70. For example, when the control unit 86 receives a request to transmit log information from the separate component 70, the control unit 86 determines that there is a request to transmit log information from the separate component 70. If there is no request to transmit log information to the separate component 70, the control unit 86 ends the process. If there is a request to transmit log information to the separate component 70, the control unit 86 proceeds to step S22.

[0098] In step S22, the control unit 86 transmits the log information to the separate component 70 and ends the process. For example, in step S22, the control unit 86 transmits all of the log information stored in the storage unit 84 to the separate component 70. In step S22, the control unit 86 may transmit only a portion of the log information stored in the storage unit 84 to the separate component 70. The request to transmit log information to the separate component 70 may specify the type of log information to be transmitted to the separate component 70.
