[0040] For example, the human-powered vehicle 10 includes a control system for the human-powered vehicle. The control system for the human-powered vehicle includes a component 40 for the human-powered vehicle, a first component 44, and a second component 46. For example, the component 40 for the human-powered vehicle includes a control device 60. For example, the component 40 for the human-powered vehicle includes at least a part of the control device 60. For example, the first component 44 and the second component 46 are configured to be powered from the battery 36 via a drive unit 34. For example, the component 40 for the human-powered vehicle communicates with the drive unit 34 and the first component 44 and the second component 46. For example, the component 40 includes a connection part 42 that communicates with the drive unit 34 and the first component 44 and the second component 46. For example, the first component 44 and the second component 46 are configured to be powered from the battery 36 via a drive unit 34 which includes a motor 34A that provides propulsion to the human-powered vehicle 10.

[0045] The transmission 50 includes, for example, at least one of a derailleur and an internal gear hub. If the transmission 50 includes an internal gear hub, it is provided, for example, on the hub of the rear wheel 14A. The internal gear hub may include a CVT (Continuously Variable Transmission).

The relationship between the gear ratio, the rotational speed of the drive wheel, and the rotational speed of the input shaft 12A is expressed by equation (1). Equation (1): Gear ratio = rotational speed of drive wheels / rotational speed of input shaft

[0048] The rotational speed of the drive wheel and the rotational speed of the input shaft 12A may both be rotations per unit time. The rotational speed of the drive wheel may be replaced with the number of teeth on the front sprocket, and the rotational speed of the input shaft 12A may be replaced with the number of teeth on the rear sprocket.

[0049] For example, one of the first component 44 and the second component 46 includes a first gearbox 50A, and the other of the first component 44 and the second component 46 includes a second gearbox 50B.

The second slave control unit 76 may include one or more microcomputers.

[0061] For example, the control device 60 further comprises a second slave storage unit 78. For example, the second slave storage unit 78 is provided in the second component 46. For example, the second slave storage unit 78 is provided in the housing of the second component 46. The second slave storage unit 78 stores a predetermined control program and information used for control processing. The second slave storage unit 78 includes, for example, non-volatile memory and volatile memory. The non-volatile memory includes, for example, at least one of ROM, EPROM, EEPROM, and flash memory. The volatile memory includes, for example, RAM.

[0062] For example, the control device 60 further comprises a second slave communication unit 80. For example, the second slave communication unit 80 is provided in the second component 46. For example, the second slave communication unit 80 is provided in the housing of the second component 46. The second slave communication unit 80 transmits and receives signals with the second master communication unit 68 according to the second communication standard.

[0063] The master control unit 62 is configured to control the first component 44 and the second component 46. The first component 44 is configured to be controlled by at least one of the master control unit 62 and the first slave control unit 70. When the first component 44 is controlled by the first slave control unit 70, the master control unit 62 is configured to restrict the operation of at least one of the first component 44 and the second component 46 based on a first operation signal transmitted from the first slave control unit 70.

[0064] The first slave control unit 70 controls the first component 44, for example, when the first slave control unit 70 determines that the operating conditions for the first component have been met. For example, the master control unit 62 is configured to determine whether or not to restrict the operation of the first component 44 before the operation of the first component 44 starts, when the first slave control unit 70 controls the first component 44.

[0065] For example, the first slave control unit 70 is configured to be autonomously controllable. For example, the second slave control unit 76 is configured to be autonomously controllable. Autonomous control is control based on the determination of whether the operating conditions of the first component are met, without relying on control commands from the master control unit 62 and the operating device, etc. For example, the autonomous control of the first slave control unit 70 includes control for adjusting the first component 44. For example, the autonomous control of the second slave control unit 76 includes control for adjusting the second component 46.

[0066] For example, the restrictions on the operation of the first component 44 and the second component 46 include at least one of delaying the start of operation and prohibiting it. For example, the master control unit 62 is configured to control the first component 44 and the second component 46 so that they do not operate simultaneously. For example, the master control unit 62 is configured to control the operation of the first component 44 and the second component 46 so that the sum of the power consumed by the operation of the first component 44 and the power consumed by the operation of the second component 46 is less than or equal to a predetermined power.

[0067] For example, the operation of the first component 44 corresponds to the driving of an electric actuator included in the first component 44. For example, the operation of the second component 46 corresponds to the driving of an electric actuator included in the second component 46. For example, if the first component 44 includes a derailleur, the operation of the first component 44 includes an operation to adjust the position of the derailleur. For example, if the second component 46 includes a derailleur, the operation of the second component 46 includes an operation to adjust the position of the derailleur.

[0068] For example, the master control unit 62 is configured to allow the operation of the second component 46 when the first component 44 is operated by the first slave control unit 70 and the first component 44 has completed its operation, or when the first component 44 is operated by the first slave control unit 70 and a first period has elapsed since the first component 44 started operating. For example, the first period is set according to the time it takes for the operation of the first component 44 to be completed.

[0069] For example, when the operation of the first component 44 is completed, the first slave control unit 70 sends a first completion signal to the master control unit 62. Based on the first completion signal, the master control unit 62 is configured to allow the operation of the second component 46.

[0070] For example, the second component 46 is configured to be controlled by at least one of the master control unit 62 and the second slave control unit 76. When the second component 46 is controlled by the second slave control unit 76, the master control unit 62 is configured to restrict the operation of at least one of the first component 44 and the second component 46 based on a second operation signal transmitted from the second slave control unit 76.

[0071] The second slave control unit 76 controls the second component 46, for example, when the second slave control unit 76 determines that the operating conditions for the second component have been met. For example, when the second slave control unit 76 controls the second component 46, the master control unit 62 is configured to determine whether or not to restrict the operation of the second component 46 before the operation of the second component 46 begins.

[0072] For example, the master control unit 62 is configured to allow the operation of the first component 44 when the second component 46 has completed its operation, or when the second component 46 has elapsed since the second component 46 started operating, if the second component 46 is operated by the second slave control unit 76. For example, the second period is set according to the time it takes for the operation of the second component 46 to complete.

[0073] For example, when the second component 46 completes its operation, the second slave control unit 76 sends a second completion signal to the master control unit 62. Based on the second completion signal, the master control unit 62 is configured to allow the first component 44 to continue operating.

[0074] For example, if the master control unit 62 restricts the operation of the second component 46, it is configured to send a second component 46 restriction signal to the second slave control unit 76 that restricts the start of the operation of the second component 46.

[0075] For example, the second slave control unit 76 is configured to control the second component 46 so that it starts operating when the second component operating conditions for starting the operation of the second component 46 are met and the second component limiting signal is not received from the master control unit 62.

[0076] For example, the second slave control unit 76 is configured to control the second component 46 so that it does not start operating when the second component operating conditions are met and the master control unit 62 receives a second component limiting signal.

[0077] For example, if the master control unit 62 restricts the operation of the first component 44, it is configured to send a first component limiting signal to the first slave control unit 70 that restricts the start of the operation of the first component 44.

[0078] For example, the first slave control unit 70 is configured to control the first component 44 so that it starts operating when the first component operating conditions for starting the operation of the first component 44 are met and it does not receive a first component limiting signal from the master control unit 62.

[0079] For example, the first slave control unit 70 is configured to control the first component 44 so that it does not start operating when the first component operating conditions are met and the master control unit 62 receives a first component limiting signal.

[0080] For example, the first slave control unit 70 is configured to switch between a first control state and a second control state. When the control state is the first control state, the first slave control unit 70 transmits a first operation signal to the master control unit 62 when the first component operation condition is met. When the control state is the second control state, the first slave control unit 70 is configured to control the first component 44 so that the first component 44 starts operating without transmitting a first operation signal to the master control unit 62 when the first component operation condition is met.

[0081] For example, the master control unit 62 transmits a switching signal to the first slave control unit 70 to switch the control state of the first slave control unit 70 between a first control state and a second control state. The first slave control unit 70 is configured to switch its control state between the first control state and the second control state based on the switching signal.

[0082] Referring to Figure 3, the process by which the master control unit 62 switches the control state between the first control state and the second control state will be explained. For example, when power is supplied to the master control unit 62, the master control unit 62 starts processing and moves to step S11 of the flowchart shown in Figure 3. When the flowchart in Figure 3 is completed, the master control unit 62 repeats the process from step S11 in Figure 3 at predetermined intervals until, for example, the power supply is stopped.

[0083] In step S11, the master control unit 62 determines whether or not it is executing the control corresponding to the first control state. For example, if the first component 44 and the second component 46 are in the first control state, the master control unit 62 determines that it is executing the control corresponding to the first control state. For example, if the master control unit 62 is controlling the first component 44 and the second component 46 to be in the first control state, it determines that it is executing the control corresponding to the first control state. If the master control unit 62 is not executing the control corresponding to the first control state, it proceeds to step S12.

[0084] In step S12, the master control unit 62 determines whether a switch from the second control state to the first control state is necessary. For example, the master control unit 62 determines that a switch from the second control state to the first control state is necessary based on at least one of the operation signal from the operating device provided on the human-powered vehicle 10 and the signal from the external device. For example, the master control unit 62 determines that a switch from the second control state to the first control state is necessary based on the remaining charge of the battery 36. If a switch from the second control state to the first control state is necessary, the master control unit 62 proceeds to step S13.

[0085] In step S13, the master control unit 62 transmits a switching signal from the second control state to the first control state and proceeds to step S14. For example, the master control unit 62 transmits a switching signal from the second control state to the first control state to the first slave control unit 70 and the second slave control unit 76.

[0086] In step S14, the master control unit 62 executes the control corresponding to the first control state and terminates the process. From step S14 onward, the master control unit 62 is configured to control the first component 44 and the second component 46 in such a way that they do not operate simultaneously.

[0087] If, in step S12, it is not necessary to switch from the second control state to the first control state, the master control unit 62 proceeds to step S15. In step S15, the master control unit 62 continues the control corresponding to the second control state and terminates the process. From step S15 onward, the master control unit 62 is configured to control the first component 44 and the second component 46 in a manner that does not restrict the simultaneous operation of the first component 44 and the second component 46.

[0088] If the master control unit 62 is executing a control corresponding to the first control state in step S11, it proceeds to step S16. In step S16, the master control unit 62 determines whether a switch from the first control state to the second control state is necessary. For example, the master control unit 62 determines whether a switch from the first control state to the second control state is necessary based on at least one of the operation signal from the operating device provided on the human-powered vehicle 10 and a signal from an external device. For example, the master control unit 62 determines whether a switch from the first control state to the second control state is necessary based on the remaining charge of the battery 36. If a switch from the first control state to the second control state is necessary, the master control unit 62 proceeds to step S17.

[0089] In step S17, the master control unit 62 transmits a switching signal from the first control state to the second control state and proceeds to step S18. For example, the master control unit 62 transmits switching signals from the first control state to the second control state to the first slave control unit 70 and the second slave control unit 76.

[0090] In step S18, the master control unit 62 executes the control corresponding to the second control state and terminates the process. From step S18 onward, the master control unit 62 is configured to control the first component 44 and the second component 46 in a manner that does not restrict the simultaneous operation of the first component 44 and the second component 46.

[0091] If, in step S16, it is not necessary to switch from the first control state to the second control state, the master control unit 62 proceeds to step S19. In step S19, the master control unit 62 continues the control corresponding to the first control state and terminates the process. From step S19 onward, the master control unit 62 is configured to control the first component 44 and the second component 46 in such a way that they do not operate simultaneously.

[0092] Referring to Figure 4, the process by which the first slave control unit 70 switches the control state between the first control state and the second control state will be explained. For example, when power is supplied to the first slave control unit 70, the first slave control unit 70 starts processing and moves to step S21 of the flowchart shown in Figure 4. When the flowchart in Figure 4 ends, the first slave control unit 70 repeats the processing from step S21 of Figure 4 at predetermined intervals, for example, until the power supply is stopped.

[0093] In step S21, the first slave control unit 70 determines whether or not the system is in the first control state. If the system is not in the first control state, the first slave control unit 70 proceeds to step S22.

[0094] In step S22, the first slave control unit 70 determines whether or not it has received a switching signal from the second control state to the first control state. For example, if the first slave control unit 70 receives a switching signal transmitted from the master control unit 62 in step S13 of Figure 3, it determines that it has received a switching signal from the second control state to the first control state. If the first slave control unit 70 has not received a switching signal from the second control state to the first control state, it terminates the process. If the first slave control unit 70 has received a switching signal from the second control state to the first control state, it proceeds to step S23.

[0095] In step S23, the first slave control unit 70 switches from the first control state to the second control state and terminates processing. From step S23 onward, the first slave control unit 70 can operate the first component 44 without communicating with the master control unit 62.

[0096] If the first slave control unit 70 is in the first control state in step S21, it proceeds to step S24.

[0097] In step S24, the first slave control unit 70 determines whether or not it has received a switching signal from the first control state to the second control state. For example, if the first slave control unit 70 receives a switching signal transmitted from the master control unit 62 in step S17 of Figure 3, it determines that it has received a switching signal from the first control state to the second control state. If the first slave control unit 70 has not received a switching signal from the first control state to the second control state, it terminates the process. If the first slave control unit 70 has received a switching signal from the first control state to the second control state, it proceeds to step S25.

[0098] In step S25, the first slave control unit 70 switches from the second control state to the first control state and terminates the process. In step S25 and beyond, if the first slave control unit 70 operates the first component 44, it operates the first component 44 based on communication with the master control unit 62.

[0099] The process by which the second slave control unit 76 switches the control state between the first control state and the second control state is performed in the same manner as the flowchart shown in Figure 4. The process by which the second slave control unit 76 is changed between the first control state and the second control state is described in the flowchart shown in Figure 4 by replacing the first slave control unit 70 with the second slave control unit 76 and replacing the first component 44 with the second component 46.

[0100] Referring to Figures 5 and 6, the process by which the master control unit 62 controls the first component 44 and the second component 46 in the first control state will be described. For example, when power is supplied to the master control unit 62, the master control unit 62 starts processing and proceeds to step S31 of the flowchart shown in Figure 5. When the flowcharts in Figures 5 and 6 are completed, the master control unit 62 repeats the processing from step S31 in Figure 5 at predetermined intervals, for example, until the power supply is stopped.

[0101] In step S31, the master control unit 62 determines whether or not it is currently executing the control corresponding to the first control state. If the master control unit 62 is not currently executing the control corresponding to the first control state, it terminates the process. If the master control unit 62 is currently executing the control corresponding to the first control state, it proceeds to step S32.

[0102] In step S32, the master control unit 62 determines whether or not it has received the first operation signal. If the master control unit 62 has received the first operation signal, it proceeds to step S33. In step S33, the master control unit 62 determines whether or not the operation of the first component is restricted. For example, if the master control unit 62 has received the second operation signal from the second component 46, has not received the second completion signal from the second component 46, and the second period has not elapsed since the second operation signal was received, it determines that the operation of the first component is restricted. If the operation of the first component is not restricted, the master control unit 62 proceeds to step S34. In step S34, the master control unit 62 transmits a first component permission signal and terminates the process.

[0103] If the master control unit 62 is limiting the operation of the first component in step S33, it proceeds to step S35. In step S35, the master control unit 62 transmits a first component limiting signal and proceeds to step S36.

[0104] In step S36, the master control unit 62 determines whether or not it has received the second completion signal. If the master control unit 62 has received the second completion signal, it proceeds to step S38. If the master control unit 62 has not received the second completion signal, it proceeds to step S37. In step S37, the master control unit 62 determines whether or not the second period has elapsed. If the second period has not elapsed, the master control unit 62 proceeds to step S36. If the second period has elapsed, the master control unit 62 proceeds to step S38.

[0105] The order of the processes in step S36 and step S37 may be reversed. Either the process in step S36 or step S37 may be omitted. If either the process in step S36 or step S37 is omitted, the master control unit 62 proceeds to step S38 if the other process in step S36 or step S37 is YES. If either the process in step S36 or step S37 is omitted, the master control unit 62 repeats the other process in step S36 or step S37 if the other process in step S37 is NO.

[0106] In step S38, the master control unit 62 transmits a first component permission signal and terminates the process.

[0107] If the master control unit 62 has not received the first operation signal in step S32, it proceeds to step S39. In step S39, the master control unit 62 determines whether or not it has received the second operation signal. If the master control unit 62 has received the second operation signal, it proceeds to step S40. In step S40, the master control unit 62 determines whether or not the operation of the second component is restricted. For example, if the master control unit 62 has received the first operation signal from the first component 44, has not received the first completion signal from the first component 44, and the first period has not elapsed since the first operation signal was received, it determines that the operation of the second component is restricted. If the operation of the second component is not restricted, the master control unit 62 proceeds to step S41. In step S41, the master control unit 62 transmits a second component enable signal and terminates processing.

[0108] If the master control unit 62 is limiting the operation of the second component in step S40, it proceeds to step S42. In step S42, the master control unit 62 transmits a second component limiting signal and proceeds to step S43.

[0109] In step S43, the master control unit 62 determines whether or not it has received the first completion signal. If the master control unit 62 has received the first completion signal, it proceeds to step S45. If the master control unit 62 has not received the first completion signal, it proceeds to step S44. In step S44, the master control unit 62 determines whether or not the first period has elapsed. If the first period has not elapsed, the master control unit 62 proceeds to step S43. If the first period has elapsed, the master control unit 62 proceeds to step S45.

[0110] The order of the processes in step S43 and step S44 may be reversed. Either the process in step S43 or step S44 may be omitted. If either the process in step S43 or step S44 is omitted, the master control unit 62 proceeds to step S45 if the other of the processes in step S36 and step S37 is YES. If either the process in step S43 or step S44 is omitted, the master control unit 62 repeats the other of the processes in step S43 and step S44 if the other of the processes in step S43 and step S44 is NO.

[0111] In step S45, the master control unit 62 transmits a second component permission signal and terminates the process.

[0112] Referring to Figure 7, the process by which the first slave control unit 70 controls the first component 44 will be described. For example, when power is supplied to the first slave control unit 70, the first slave control unit 70 starts processing and proceeds to step S51 of the flowchart shown in Figure 7. When the flowchart in Figure 7 is completed, the first slave control unit 70 repeats the processing from step S51 of Figure 7 at predetermined intervals, for example, until the power supply is stopped.

[0113] In step S51, the first slave control unit 70 determines whether or not the first component operating condition has been met. If the first component operating condition has not been met, the first slave control unit 70 terminates the process. If the first component operating condition has been met, the first slave control unit 70 proceeds to step S52.

[0114] In step S52, the first slave control unit 70 determines whether or not it is in the first control state. If it is in the first control state, the first slave control unit 70 proceeds to step S53. In step S53, the first slave control unit 70 transmits the first operation signal to the master control unit 62 and proceeds to step S54.

[0115] In step S54, the first slave control unit 70 determines whether or not it has received a first component limiting signal from the master control unit 62. If the first slave control unit 70 has not received a first component limiting signal from the master control unit 62, it proceeds to step S56. If the first slave control unit 70 has received a first component limiting signal from the master control unit 62, it proceeds to step S55.

[0116] In step S55, the first slave control unit 70 determines whether or not it has received a first component permission signal from the master control unit 62. If the first slave control unit 70 has received a first component permission signal from the master control unit 62, it proceeds to step S56.

[0117] In step S56, the first slave control unit 70 starts the operation of the first component 44 and proceeds to step S57. In step S57, the first slave control unit 70 determines whether the operation of the first component 44 has been completed. If the operation of the first component 44 has not been completed, the first slave control unit 70 repeats the process in step S57. If the operation of the first component 44 has been completed, the first slave control unit 70 proceeds to step S58.

[0118] In step S58, the first slave control unit 70 transmits a first completion signal to the master control unit 62 and terminates the process.

[0119] If the first slave control unit 70 has not received a first component permission signal from the master control unit 62 in step S55, it proceeds to step S59. In step S59, the first slave control unit 70 determines whether or not the operation termination condition is met. The operation termination condition is met, for example, when a first predetermined time has elapsed since the first component operation condition was met. If the operation termination condition is not met, the first slave control unit 70 proceeds to step S55. If the operation termination condition is met, the first slave control unit 70 terminates processing.

[0120] If the first slave control unit 70 is not in the first control state in step S52, it proceeds to step S60. In step S60, the first slave control unit 70 starts the operation of the first component 44 and terminates the process.

[0121] Referring to Figure 8, the process by which the second slave control unit 76 controls the second component 46 will be described. For example, when power is supplied to the second slave control unit 76, the second slave control unit 76 starts processing and proceeds to step S71 of the flowchart shown in Figure 8. When the flowchart in Figure 8 ends, the second slave control unit 76 repeats the processing from step S71 of Figure 8 at predetermined intervals, for example, until the power supply is stopped.

[0122] In step S71, the second slave control unit 76 determines whether the operating conditions for the second component have been met. If the operating conditions for the second component have not been met, the second slave control unit 76 terminates the process. If the operating conditions for the second component have been met, the second slave control unit 76 proceeds to step S72.

[0123] In step S72, the second slave control unit 76 determines whether or not the first control state is in effect. If the first control state is in effect, the second slave control unit 76 proceeds to step S73. In step S73, the second slave control unit 76 transmits a second operation signal to the master control unit 62 and proceeds to step S74.

[0124] In step S74, the second slave control unit 76 determines whether or not it has received a second component limiting signal from the master control unit 62. If the second slave control unit 76 has not received a second component limiting signal from the master control unit 62, it proceeds to step S76. If the second slave control unit 76 has received a second component limiting signal from the master control unit 62, it proceeds to step S75.

[0125] In step S75, the second slave control unit 76 determines whether or not it has received a second component permission signal from the master control unit 62. If the second slave control unit 76 has received a second component permission signal from the master control unit 62, it proceeds to step S76.

[0126] In step S76, the second slave control unit 76 starts the operation of the second component 46 and proceeds to step S77. In step S77, the second slave control unit 76 determines whether the operation of the second component 46 has been completed. If the operation of the second component 46 has not been completed, the second slave control unit 76 repeats the process in step S77. If the operation of the second component 46 has been completed, the second slave control unit 76 proceeds to step S78.

[0127] In step S78, the second slave control unit 76 transmits a second completion signal to the master control unit 62 and terminates the process.

[0128] If the second slave control unit 76 has not received a second component permission signal from the master control unit 62 in step S75, it proceeds to step S79. In step S79, the second slave control unit 76 determines whether or not the operation termination condition is met. The operation termination condition is met, for example, when a second predetermined time has elapsed since the second component operation condition was met. If the operation termination condition is not met, the second slave control unit 76 proceeds to step S75. If the operation termination condition is met, the second slave control unit 76 terminates processing.

[0129] If the second slave control unit 76 is not in the first control state in step S72, it proceeds to step S80. In step S80, the second slave control unit 76 starts the operation of the second component 46 and terminates the process.

[0130] The control device 60 can restrict the simultaneous operation of the first component 44 and the second component 46 in the first control state by the processes shown in Figures 3 to 8. Therefore, the control device 60 can control the first component 44 and the second component 46 so that the sum of the power consumed by the operation of the first component 44 and the power consumed by the operation of the second component 46 is less than or equal to a predetermined power.

[0131] For example, the master control unit 62 is configured to control the first component 44 and the second component 46 in response to the occurrence of an abnormality. For example, the master control unit 62 determines that an abnormality has occurred when the temperature of the drive unit 34 reaches a predetermined temperature. For example, the master control unit 62 determines that an abnormality has occurred when the remaining charge of the battery 36 falls below a predetermined level.

[0132] For example, the master control unit 62 is configured to control the first component 44 and the second component 46 so that they do not operate when an abnormality occurs. For example, the master control unit 62 is configured to send an operation stop signal to the first slave control unit 70 and the second slave control unit 76 so that the first component 44 and the second component 46 do not operate when an abnormality occurs.

[0133] Referring to Figure 9, the process by which the master control unit 62 controls the first component 44 and the second component 46 in response to the occurrence of an abnormality will be explained. For example, when power is supplied to the master control unit 62, the master control unit 62 starts processing and proceeds to step S91 of the flowchart shown in Figure 9. When the flowchart in Figure 9 is completed, the master control unit 62 repeats the process from step S91 of Figure 9 at predetermined intervals, for example, until the power supply is stopped.

[0134] In step S91, the master control unit 62 determines whether or not an abnormality has occurred. If no abnormality has occurred, the master control unit 62 terminates the process. If an abnormality has occurred, the master control unit 62 proceeds to step S92. In step S92, the master control unit 62 transmits an operation termination signal and proceeds to step S93.

[0135] In step S93, the master control unit 62 determines whether or not it has received a recognition signal. If the master control unit 62 has received a recognition signal, it terminates the process. If the master control unit 62 has not received a recognition signal, it proceeds to step S94. In step S94, the master control unit 62 determines whether or not the third period has elapsed. For example, if the period since the abnormality occurred in step S91 is three periods or longer, the master control unit 62 determines that the third period has elapsed. If the third period has not elapsed, the master control unit 62 proceeds to step S92. If the third period has elapsed, the master control unit 62 proceeds to step S95.

[0136] In step S95, the master control unit 62 performs abnormality control and terminates the process. In abnormality control, the master control unit 62 shuts out the first slave control unit 70 and the second slave control unit 76, for example. In abnormality control, the master control unit 62 stops supplying power to the first slave control unit 70 and the second slave control unit 76, for example.

[0137] Referring to Figure 10, the process by which the first slave control unit 70 controls the first component 44 in response to the occurrence of an abnormality will be described. For example, when power is supplied to the first slave control unit 70, the first slave control unit 70 starts processing and proceeds to step S101 of the flowchart shown in Figure 10. When the flowchart in Figure 10 is completed, the first slave control unit 70 repeats the processing from step S101 of Figure 10 at predetermined intervals, for example, until the power supply is stopped.

[0138] In step S101, the first slave control unit 70 determines whether or not it has received an operation stop signal. If the first slave control unit 70 has not received an operation stop signal, it terminates the process. If the first slave control unit 70 has received an operation stop signal, it proceeds to step S102.

[0139] In step S102, the first slave control unit 70 determines whether the first component 44 is operating or not. If the first component 44 is operating, the first slave control unit 70 proceeds to step S103. In step S103, the first slave control unit 70 terminates the operation of the first component 44 and proceeds to step S104. In step S104, the first slave control unit 70 transmits an operation in progress signal and a recognition signal to the master control unit 62 and terminates processing.

[0140] If the first component 44 is not operating in step S102, the first slave control unit 70 proceeds to step S105. In step S105, the first slave control unit 70 disables the operation of the first component 44, sends a recognition signal to the master control unit 62, and terminates the process.

[0141] The process by which the second slave control unit 76 controls the second component 46 in response to an abnormality is performed in the same manner as the flowchart shown in Figure 10. The process by which the second slave control unit 76 is changed between the first control state and the second control state is described in the flowchart shown in Figure 10 by replacing the first slave control unit 70 with the second slave control unit 76 and the first component 44 with the second component 46.

[0142] The control device 60, through the processes shown in Figures 9 and 10, allows the master control unit 62 to restrict the operation of the first slave control unit 70 and the second slave control unit 76 when an abnormality occurs.

[0143] For example, the master control unit 62, the first slave control unit 70, and the second slave control unit 76 are each set with identification information for communication and control. For example, the master control unit 62 is configured to update at least one of the identification information of the master control unit 62, the first slave control unit 70, and the second slave control unit 76 in response to a signal from an external device.

[0144] Identification information is, for example, an ID that is automatically assigned to each slave control unit according to the communication standard. For example, if the maximum number of IDs is small, such as in CAN, duplicate IDs can be suppressed by manually updating the identification information.

[0145] Referring to Figure 11, the process by which the master control unit 62 updates identification information will be explained. For example, when power is supplied to the master control unit 62, the master control unit 62 starts processing and proceeds to step S111 of the flowchart shown in Figure 11. When the flowchart in Figure 11 is completed, the master control unit 62 repeats the process from step S111 of Figure 11 at predetermined intervals, for example, until the power supply is stopped.

[0146] In step S111, the master control unit 62 determines whether or not there is a request to update the identification information. If there is no request to update the identification information, the master control unit 62 terminates the process. If there is a request to update the identification information, the master control unit 62 proceeds to step S112. In step S112, the master control unit 62 updates the identification information and terminates the process.
