The first receiver 66A and the first transmitter 66B constitute, for example, a first communication unit 66. The first communication unit 66 is configured to be capable of wireless communication, for example.

[0061] The head protection device 70 is, for example, a helmet that can be worn by a passenger of the human-powered vehicle 10. If the human-powered vehicle 10 includes a seat other than the driver's, such as a child seat, the passenger includes at least one of the driver and a passenger. The head protection device 70 may include something other than a helmet as long as it protects the passenger's head. The head protection device 70 may include, for example, an airbag that inflates to cover the passenger's head when at least one of the passenger and the human-powered vehicle 10 is subjected to an impact. If the head protection device 70 includes an airbag, the head protection device 70 may be worn on at least one of the passenger's neck and back.

[0062] The head protection device 70 for a human-powered vehicle can be worn by a passenger of the human-powered vehicle 10. The head protection device 70 includes, for example, a main body 72. The main body 72 is configured to be wearable on the body of the passenger. The head protection device 70 further includes a belt 74 for attaching the head protection device 70 to the passenger. When the head protection device 70 includes a helmet, the belt 74 is configured to be attached to the passenger's chin, for example.

[0063] The head protection device 70 includes, for example, a control unit 76. In this embodiment, the control unit 62 of the head protection device 70 may be referred to as a second control unit 76. For example, the second control unit 76 includes a processing unit that executes a predetermined control program. For example, the processing unit included in the second control unit 76 includes a CPU or an MPU.

[0064] For example, the arithmetic processing units included in the second control unit 76 may be provided in multiple locations that are separate from one another. When the arithmetic processing units are provided in multiple locations that are separate from one another, the respective parts of the arithmetic processing units may be connected to each other so that they can communicate with each other via a wireless communication device. The second control unit 76 may include one or more microcomputers.

[0065] For example, the head protection device 70 further includes a second memory unit 78. For example, the second memory unit 78 is communicably connected to the second control unit 76 by wire or wirelessly. For example, the second memory unit 78 stores a control program and information used in the control process. For example, the memory unit 64 includes, for example, a nonvolatile memory and a volatile memory. For example, the nonvolatile memory includes at least one of a ROM, an EPROM, an EEPROM, and a flash memory. For example, the volatile memory includes a RAM.

[0066] The head protection device 70 includes, for example, a wearing detection unit 80 configured to detect whether the head protection device 70 is being worn by the occupant, and a transmission unit 82 capable of transmitting predetermined information relating to the wearing state detected by the wearing detection unit 80 to an external device. The external device includes the control device 60. Instead of or in addition to the control device 60, the external device may include at least one of a personal computer, a smartphone, a tablet computer, and a server.

[0067] The wearing detection unit 80 outputs a signal corresponding to the wearing state of the head protection device 70 by the occupant. The wearing detection unit 80 is provided, for example, in a portion of the main body 72 facing the body of the occupant. The wearing detection unit 80 is configured, for example, to be able to detect the position of the occupant's head relative to the head protection device 70. The wearing detection unit 80 may be configured, for example, to detect the position of the occupant's head relative to the head protection device 70 based on information from a sensor that detects a reflected signal. The wearing detection unit 80 includes, for example, a signal emitting unit and a signal detecting unit. The signal emitting unit, for example, emits light. The signal detecting unit, for example, receives the reflected light. The wearing detection unit 80 is configured, for example, to be able to detect at least one of the occupant's body and the distance to the occupant's body. The wearing detection unit 80 includes, for example, at least one of an optical sensor, an ultrasonic sensor, and a distance sensor. The wearing detection unit 80 may be configured to output a signal corresponding to contact between the inner surface of the main body 72 and the occupant's head. When the wearing detection unit 80 is configured to output a signal in response to contact between the inner surface of the main body 72 and the occupant's head, the wearing detection unit 80 includes, for example, at least one of a pressure sensor and a switch. The wearing detection unit 80 may be configured to detect the connection state of the belt 74. The wearing detection unit 80 is configured, for example, to detect the attachment state of the belt 74. For example, when the belt 74 includes a free end, the attachment state of the belt 74 includes the attachment state of the free end of the belt 74 and a belt connection part. The belt connection part is provided, for example, on the main body 72 or the free end of an additional belt attached to the main body 72.

[0068] The head protection device 70 includes a transmitter 82 capable of transmitting, for example, predetermined information relating to the wearing state to the control device 60. In this embodiment, the transmitter 82 of the head protection device 70 may be referred to as a second transmitter 82. The head protection device 70 may further include a second receiver 84 configured to receive information. The second transmitter 82 and the second receiver 84 constitute, for example, a second communication unit 86. The second communication unit 86 is configured to be capable of wireless communication, for example.

[0069] The head protection device 70 further includes, for example, a power source 88 that supplies power to the second control unit 76. The power source 88 includes, for example, a second battery 90. The second battery 90 includes one or more battery elements. The battery element includes a rechargeable battery. For example, the second battery 90 is configured to supply power to the second control unit 76, the wearing detection unit 80, and the communication unit 86. The second battery 90 may be communicably connected to the second control unit 76 by wire or wirelessly. For example, the second battery 90 can communicate with the second control unit 76 via power line communication, CAN, or UART.

[0070] The wearing state includes, for example, a first wearing state in which the head protection device 70 is worn by the occupant and a second wearing state in which the head protection device 70 is not worn by the occupant. The predetermined information includes, for example, information indicating whether the wearing state is the first wearing state or the second wearing state. The second control unit 76 is configured, for example, to control the second transmission unit 82 to transmit the predetermined information when the wearing state changes. The predetermined information includes at least one of information that the wearing state is the first wearing state and information that the wearing state is the second wearing state. The predetermined information may include at least one of attachment information indicating that the wearing state has changed from the second wearing state to the first wearing state and detachment information indicating that the wearing state has changed from the first wearing state to the second wearing state. The second control unit 76 is configured, for example, to control the second transmission unit 82 to transmit detachment information when the wearing state changes from the first wearing state to the second wearing state. The second control unit 76 is configured, for example, to control the second transmission unit 82 so that when the second reception unit 84 receives a request to transmit the predetermined information from the control device 60, the second reception unit 84 transmits the predetermined information.

[0071] When the wearing detection unit 80 is configured to be able to detect the position of the occupant's head relative to the head protection device 70, the second control unit 76 determines that the wearing state is in the first state, for example, when the occupant's head is within a predetermined distance from the head protection device 70. When the wearing detection unit 80 is configured to be able to detect the position of the occupant's head relative to the head protection device 70, the second control unit 76 determines that the wearing state is in the second state, for example, when the occupant's head is out of the predetermined distance from the head protection device 70. When the wearing detection unit 80 is configured to output a signal in response to contact between the inner surface of the main body 72 and the occupant's head, the second control unit 76 determines that the wearing state is in the first state, for example, when the output signal from the wearing detection unit 80 is a signal corresponding to a state in which the inner surface of the main body 72 and the occupant's head are in contact. When the wearing detection unit 80 is configured to output a signal corresponding to contact between the inner surface of the main body 72 and the occupant's head, the second control unit 76 determines that the wearing state is the second state, for example, when the output signal of the wearing detection unit 80 is a signal corresponding to a state in which the inner surface of the main body 72 and the occupant's head are not in contact. When the wearing detection unit 80 is configured to be able to detect the connection state of the belt 74, the second control unit 76 determines that the wearing state is the first state, for example, when the belt 74 is connected to the belt attachment part. When the wearing detection unit 80 is configured to be able to detect the connection state of the belt 74, the second control unit 76 determines that the wearing state is the second state, for example, when the belt 74 is not connected to the belt attachment part.

[0072] The control unit 62 of the control device 60 is configured to control the component 42 for the human-powered vehicle based on, for example, the wearing state of the head protection device 70 that can be worn by a passenger of the human-powered vehicle 10. The control unit 62 is configured to control the component 42 to change the control state of the component 42 between a first control state and a second control state based on, for example, the wearing state. The control unit 62 of the control device 60 is configured to control the component 42 based on, for example, predetermined information. The control unit 62 is configured to control the component 42 to change the control state of the component 42 between the first control state and the second control state based on, for example, the predetermined information. For example, when the wearing state is the first wearing state, the control unit 62 sets the control state of the component 42 to the first control state. For example, when the wearing state is the second wearing state, the control unit 62 sets the control state of the component 42 to the second control state.

[0073] When the component 42 includes the restriction device 46, the control unit 62 is configured to control the restriction device 46 based on, for example, the wearing state. When the component 42 includes the restriction device 46, the first control state includes, for example, a release state. When the component 42 includes the restriction device 46, the second control state includes, for example, a restricted state. The first control unit 62 is configured to control the restriction device 46 to switch the state of the restriction device 46 from the restricted state to the release state when the wearing state is the first wearing state. The first control unit 62 is configured to control the restriction device 46 to maintain the state of the restriction device 46 in the restricted state when the wearing state is the second wearing state. The first control unit 62 is configured to control the restriction device 46 to maintain the state of the restriction device 46 in the restricted state when the wearing state is the second wearing state. The first control unit 62 is configured to control the restriction device 46 so that, for example, when the wearing state is the second wearing state, the state of the restriction device 46 is maintained in the restricted state even if a release operation is performed using a key or release information is input.

[0074] When the component 42 includes the limiting device 46, the control unit 62 is configured to control the motor 48 based on the wearing state, for example. When the component 42 includes the motor 48, the first control unit 62 is configured to control the motor 48, for example, in the second control state so that the assist force of the motor 48 is smaller than that in the first control state. When the wearing state is the second wearing state, for example, the first control unit 62 is configured to control the motor 48 so that the motor 48 does not provide propulsion force to the human-powered vehicle 10. The first control unit 62 is configured to control the motor 48 so that the assist force of the motor 48 when the wearing state is the second wearing state is smaller than the assist force of the motor 48 when the wearing state is the first wearing state.

[0075] The control unit 62 may be configured to change the power consumption state of the component 42 based on the wearing state. The power consumption states include, for example, a first power consumption state and a second power consumption state in which power consumption is lower than that of the first power consumption state. The first control state includes, for example, the first power consumption state. The second control state includes, for example, the second power consumption state. The second power consumption state corresponds, for example, to a sleep mode. When the power consumption state is the second power consumption state, for example, at least some of the functions of the component 42 are limited compared to when the power consumption state is the first power consumption state. For example, when the wearing state is the first wearing state, the first control unit 62 sets the power consumption state to the first power consumption state. For example, when the wearing state is the second wearing state, the first control unit 62 sets the power consumption state to the second power consumption state. For example, when the wearing state changes from the second wearing state to the first wearing state in the second power consumption state, the first control unit 62 switches the power consumption state from the second power consumption state to the first power consumption state. For example, when the wearing state changes from the first wearing state to the second wearing state in the first power consumption state, the first control unit 62 switches the power consumption state from the first power consumption state to the second power consumption state.

[0076] The process of transmitting predetermined information by the second control unit 76 will be described with reference to Fig. 4. For example, when power is supplied to the second control unit 76, the second control unit 76 starts the process and proceeds to step S11 of the flowchart shown in Fig. 4. When the flowchart of Fig. 4 ends, the second control unit 76 repeats the process from step S11 after a predetermined period, for example, until the supply of power is stopped.

[0077] In step S11, the second control unit 76 determines whether the wearing state is the first wearing state. If the wearing state is the first wearing state, the second control unit 76 proceeds to step S12. In step S12, the second control unit 76 selects the first communication state from the communication state of the second communication unit 86 with the first communication unit 66, and proceeds to step S13. The first communication state is, for example, a state in which the second communication unit 86 can communicate with the first communication unit 66. For example, in step S16, if the communication state of the second communication unit 86 with the first communication unit 66 is the second communication state, the control unit 76 switches the communication state from the second communication state to the first communication state. In step S13, the second control unit 76 transmits predetermined information and ends the process. The predetermined information transmitted in step S13 includes information that the wearing state is the first wearing state.

[0078] If the wearing state is not the first wearing state in step S11, the second control unit 76 proceeds to step S14. In step S14, the second control unit 76 determines whether the wearing state has transitioned from the first wearing state to the second wearing state. If the wearing state has transitioned from the first wearing state to the second wearing state, the second control unit 76 proceeds to step S15. In step S13, the second control unit 76 transmits removal information and proceeds to step S16. In step S16, the control unit 76 selects the second communication state from the communication state of the second communication unit 86 with the first communication unit 66 and ends the processing. The second communication state is, for example, a state in which the second communication unit 86 does not communicate with the first communication unit 66. In step S16, the control unit 76 switches the communication state of the second communication unit 86 with the first communication unit 66 from the first communication state to the second communication state.

[0079] If the wearing state has not transitioned from the first wearing state to the second wearing state in step S14, the second control unit 76 ends the process. The cases in which the second control unit 76 determines that the wearing state has not transitioned from the first wearing state to the second wearing state include, for example, the cases in which the wearing state is maintained in the second wearing state.

[0080] In the process of FIG. 4 , when the wearing state is the first wearing state, the second control unit 76 may be configured to transmit predetermined information including information that the wearing state is the first wearing state to the control device 60 at predetermined intervals, but may also be configured to control the second transmission unit 82 to transmit the predetermined information to the control device 60 only when the wearing state transitions from the second wearing state to the first wearing state. The second control unit 76 may be configured to control the second transmission unit 82 to transmit the predetermined information to the control device 60 only once when the wearing state transitions from the second wearing state to the first wearing state. For example, instead of the process of step S11, the second control unit 76 is configured to determine whether the wearing state transitions from the second wearing state to the first wearing state. For example, when the wearing state transitions from the second wearing state to the first wearing state, the second control unit 76 proceeds to step S12. For example, when the wearing state transitions from the second wearing state to the first wearing state, the second control unit 76 may transmit the attachment information and proceed to step S12. For example, if the wearing state has not shifted from the second wearing state to the first wearing state, the second control unit 76 proceeds to step S14.

[0081] The process by which the first control unit 62 changes the control state of the component 42 will be described with reference to Fig. 5. For example, when power is supplied to the first control unit 62, the first control unit 62 starts the process and proceeds to step S21 of the flowchart shown in Fig. 5. When the flowchart of Fig. 5 ends, the first control unit 62 repeats the process from step S21 after a predetermined period, for example, until the supply of power is stopped.

[0082] In step S21, the first control unit 62 determines whether or not predetermined information has been received. For example, when the first control unit 62 receives information indicating that the wearing state is the first wearing state or predetermined information including attachment information, the first control unit 62 determines that the predetermined information has been received. When the first control unit 62 receives the predetermined information, the first control unit 62 proceeds to step S22. In step S22, the first control unit 62 switches the control state to the first control state and ends the processing.

[0083] If the first control unit 62 has not received the predetermined information in step S21, it proceeds to step S23. In step S23, the first control unit 62 determines whether or not detachment information has been received. If the first control unit 62 has received the detachment information, it proceeds to step S24. In step S24, the first control unit 62 switches the control state to the second control state and ends the processing. If the first control unit 62 has not received the detachment information in step S23, it ends the processing.

[0084] For example, instead of the processing of step S23, the first control unit 62 may determine whether or not predetermined information including information indicating that the wearing state is the second wearing state has been received. If the first control unit 62 has received predetermined information including information indicating that the wearing state is the second wearing state, the first control unit 62 proceeds to step S24. If the first control unit 62 has not received predetermined information including information indicating that the wearing state is the second wearing state, the first control unit 62 ends the processing.

[0085] Second Embodiment A head-protecting device 70 for a human-powered vehicle according to a second embodiment will be described with reference to Figures 6 to 9. In the head-protecting device 70 according to the second embodiment, components common to those in the first embodiment are designated by the same reference numerals as in the first embodiment, and redundant explanations will be omitted.

[0086] The head protection device 70 of this embodiment includes a power source 88, a wearing detection unit 80, a display unit 92, and a control unit 76. The display unit 92 is configured to be able to display the remaining power of the power source 88. The control unit 76 is configured to control the display unit 92. The control unit 76 is configured to control the display unit to change the display state of the remaining power on the display unit 92 based on the wearing state detected by the wearing detection unit 80. In this embodiment, the head protection device 70 does not need to include the second communication unit 86.

[0087] The display unit 92 is provided, for example, on the outer surface of the head protection device 70. The display unit 92 is provided, for example, in a position on the main body 72 that is visible to the occupant when the occupant is not wearing the head protection device 70. The display unit 92 includes, for example, a light-emitting unit. The light-emitting unit includes, for example, an LED (Light Emitting Diode). The display unit 92 may include a liquid crystal display. When the display unit 92 includes a light-emitting unit, the remaining power is represented, for example, by at least one of a lit state, a flashing state, an off state, and a lit color.

[0088] Head protection device 70 further includes, for example, a motion detection unit 94 that detects motion of head protection device 70. Motion detection unit 94 is configured to be able to detect, for example, when head protection device 70 is in a stationary state. The stationary state is, for example, when head protection device 70 is placed in a storage location. Motion detection unit 94 includes, for example, at least one of an acceleration sensor and a gyro sensor.

[0089] The control unit 76 is configured to control the display unit 92 to change the display state, for example, when the wearing state is changed from one of the first wearing state and the second wearing state to the other of the first wearing state and the second wearing state. The second control unit 76 is configured to control the display unit 92 to display the remaining power, for example, when the wearing state is changed from one of the first wearing state and the second wearing state to the other of the first wearing state and the second wearing state. The second control unit 76 is configured to control the display unit 92 to display the remaining power, for example, when the wearing state is changed from the first wearing state to the second wearing state. The second control unit 76 is configured to control the display unit 92 to change from an off state to one of an on state and a flashing state, for example, when the wearing state is changed from the first wearing state to the second wearing state. The second control unit 76 is configured to control the display unit 92 to display the remaining power, for example, when the occupant prepares the head protection device 70 to wear it and when the occupant removes the head protection device 70 from their body.

[0090] The control unit 76 is configured, for example, in the second wearing state, to control the display unit 92 to start displaying the remaining power when the movement detection unit 94 detects movement of the head protection device 70. The second control unit 76 is configured, for example, to control the display unit 92 to start displaying the remaining power when the head protection device 70 changes from a stationary state to a non-stationary state. The control unit 76 is configured, for example, to control the display unit 92 to end displaying the remaining power when the wearing state is changed from the second wearing state to the first wearing state. The second control unit 76 is configured, for example, in the first wearing state, to control the display unit 92 not to start displaying the remaining power even when the movement detection unit 94 detects movement of the head protection device 70. The second control unit 76 is configured, for example, in the first wearing state, to control the display unit 92 not to start displaying the remaining power even when the head protection device 70 changes from a stationary state to a non-stationary state.

[0091] The control unit 76 is configured to, for example, control the display unit 92 to start displaying the remaining power when the wearing state is changed from the first wearing state to the second wearing state. The control unit 76 is configured to, for example, control the display unit 92 to stop displaying the remaining power when the head protecting device 70 becomes stationary after the wearing state is changed from the first wearing state to the second wearing state.

[0092] 8 and 9, a process in which the second control unit 76 controls the display unit 92 will be described. For example, when power is supplied to the second control unit 76, the second control unit 76 starts the process and proceeds to step S31 of the flowchart shown in Fig. 8. When the flowcharts of Fig. 8 and 9 end, the second control unit 76 repeats the process from step S31 after a predetermined period, for example, until the supply of power is stopped.

[0093] In step S31, the second control unit 76 determines whether the head protection device 70 is in a stationary state. For example, if the wearing state is the first wearing state, the second control unit 76 determines that the head protection device 70 is not in a stationary state. The second control unit 76 may determine that the head protection device 70 is in a stationary state if the wearing state is the second wearing state and the remaining power amount is not displayed on the display unit 92. The second control unit 76 may determine that the head protection device 70 is in a stationary state if a predetermined time has passed since the wearing state changed from the first wearing state to the second wearing state. If the head protection device 70 is in a stationary state, the second control unit 76 proceeds to step S32.

[0094] In step S32, the second control unit 76 determines whether or not motion has been detected. For example, the second control unit 76 determines that motion has been detected when the detection value of the motion detection unit 94 is equal to or greater than a first predetermined value, and when the state in which the detection value of the motion detection unit 94 is equal to or greater than a second predetermined value continues for equal to or greater than a first predetermined time. If motion has not been detected, the second control unit 76 ends the process. If motion has been detected, the second control unit 76 proceeds to step S33.

[0095] In step S33, the second control unit 76 causes the display unit 92 to display the remaining battery power, and proceeds to step S34. In step S34, the second control unit 76 determines whether a first predetermined time has elapsed. For example, the second control unit 76 determines that the first predetermined time has elapsed if the first predetermined time has elapsed since the second control unit 76 caused the display unit 92 to display the remaining battery power in step S33. If the first predetermined time has elapsed, the second control unit 76 proceeds to step S36. If the first predetermined time has not elapsed, the second control unit 76 proceeds to step S35. In step S35, the second control unit 76 determines whether the wearing state has changed from the second wearing state to the first wearing state. If the wearing state has not changed from the second wearing state to the first wearing state, the second control unit 76 proceeds to step S34. If the wearing state has changed from the second wearing state to the first wearing state, the second control unit 76 proceeds to step S36.

[0096] In step S36, the second control unit 76 controls the display unit 92 to end the display of the remaining battery power, and ends the process. When the processes of steps S34 and S35 determine that at least one of the first predetermined time has elapsed and the wearing state has changed from the second wearing state to the first wearing state, the second control unit 76 can end the display of the remaining battery power.

[0097] If the second control unit 76 determines in step S31 that the device is not in a stationary state, the process proceeds to step S37. In step S37, the second control unit 76 determines whether the wearing state has changed from the first wearing state to the second wearing state. If the wearing state has not changed from the first wearing state to the second wearing state, the second control unit 76 ends the process. If the wearing state has changed from the first wearing state to the second wearing state, the second control unit 76 proceeds to step S38.

[0098] In step S38, the second control unit 76 causes the display unit 92 to display the remaining power, and proceeds to step S39. In step S39, the second control unit 76 determines whether a second predetermined time has elapsed. If the second predetermined time has not elapsed, the second control unit 76 repeats the processing of step S39. If the second predetermined time has elapsed, the second control unit 76 proceeds to step S40. In step S40, the second control unit 76 controls the display unit 92 to end the display of the remaining battery power, and ends the processing. In this embodiment, the second predetermined time is different from the first predetermined time. The second predetermined time may be the same as the first predetermined time.

[0099] Third Embodiment A head-protecting device 70 for a human-powered vehicle according to a third embodiment will be described with reference to Figures 10 to 13. With regard to head-protecting device 70 according to the third embodiment, components common to those of the first and second embodiments are designated by the same reference numerals as those of the first and second embodiments, and redundant description will be omitted.

[0100] Head protection device 70 of this embodiment includes a wearing detection unit 80 configured to detect whether head protection device 70 is being worn by a passenger, an impact mitigation unit 96, and a control unit 76 configured to control impact mitigation unit 96. In this embodiment, head protection device 70 does not necessarily have to include second communication unit 86.

[0101] The head protection device 70 further includes, for example, an impact detection unit 98. For example, when an impact is detected by the impact detection unit 98, the second control unit 76 operates the impact mitigation unit 96 to mitigate the impact on the occupant's head. The impact mitigation unit 96 includes, for example, an airbag. For example, the airbag is provided on at least one of the outer peripheral surface and the top surface of the main body 72. The airbag may also be provided on the surface of the main body 72 that faces the occupant's body.

[0102] The control unit 76 is configured to control the impact mitigation unit 96 based on the wearing state detected by the wearing detection unit 80, for example. The control unit 76 is configured to control the impact mitigation unit 96 in either a first operating state in which the impact mitigation unit 96 is activated or a second operating state in which the activation of the impact mitigation unit 96 is suppressed more than in the first operating state. The control unit 76 is configured to control the impact mitigation unit 96 in the second operating state, for example, when the head protection device 70 is not being worn. When the operating state of the impact mitigation unit 96 is the second operating state, the second control unit 76 is configured to control the impact mitigation unit 96 so as not to activate the impact mitigation unit 96, for example, even if an impact is detected by the impact detection unit 98. When the wearing state is the second wearing state, the second control unit 76 may prevent the impact mitigation unit 96 from activating by controlling the impact detection unit 98 to stop the impact detection by the impact detection unit 98.

[0103] The process of the second control unit 76 controlling the impact absorbing unit 96 will be described with reference to Fig. 12. For example, when power is supplied to the second control unit 76, the second control unit 76 starts the process and proceeds to step S51 of the flowchart shown in Fig. 12. When the flowchart of Fig. 12 ends, the second control unit 76 repeats the process from step S51 after a predetermined period, for example, until the supply of power is stopped.

[0104] In step S51, the second control unit 76 determines whether the wearing state is the first wearing state. If the wearing state is the first wearing state, the second control unit 76 proceeds to step S52. In step S52, the second control unit 76 sets the operation state of the impact absorbing unit 96 to the first operation state, and proceeds to step S53.

[0105] In step S53, the second control unit 76 determines whether or not an impact has been detected. If an impact has not been detected, the second control unit 76 ends the process. If an impact has been detected, the second control unit 76 proceeds to step S54. In step S54, the second control unit 76 activates the impact absorbing unit 96 and ends the process.

[0106] If the second control unit 76 determines in step S51 that the wearer is not in the first wearing state, the second control unit 76 proceeds to step S55. In step S55, the second control unit 76 sets the operating state of the impact absorbing unit 96 to the second operating state, and ends the process.

[0107] The second control unit 76 may be configured to determine whether the wearing state is the first wearing state or the second wearing state based on the wearing state stored in the second storage unit 78. The second control unit 76 is configured to control the impact absorbing unit 96 based on the determination result of the wearing state based on the wearing state stored in the second storage unit 78, for example.

[0108] The second control unit 76 is configured to store, for example, in the second memory unit 78, a determination result of the wearing state corresponding to the number of times a wearing signal is received from the wearing detection unit 80. The wearing detection unit 80 may be configured, for example, to transmit a wearing signal to the second control unit 76 at predetermined intervals when the occupant is wearing the head protection device 70. The predetermined interval is, for example, equal to the detection interval of the wearing detection unit 80. The second control unit 76 may be configured to determine the wearing state corresponding to the number of times a wearing signal is received from the wearing detection unit 80. The second control unit 76 may be configured to control the impact mitigation unit 96 based on the determination result of the wearing state corresponding to the number of times a wearing signal is received from the wearing detection unit 80.

[0109] 13, a process in which the second control unit 76 determines the wearing state depending on the number of times the wearing signal is received from the wearing detection unit 80 will be described. For example, when power is supplied to the second control unit 76, the second control unit 76 starts the process and proceeds to step S61 of the flowchart shown in Fig. 13. When the flowchart in Fig. 13 ends, the second control unit 76 repeats the process from step S61 after a predetermined period, for example, until the supply of power is stopped.

[0110] In step S61, the second control unit 76 determines whether or not a wearing signal has been received from the wearing detection unit 80. If the second control unit 76 has received a wearing signal from the wearing detection unit 80, the process proceeds to step S62. In step S62, the second control unit 76 determines whether or not the wearing signal has been received N times in succession, where N is any natural number. If the second control unit 76 has received the wearing signal N times in succession, the process proceeds to step S63. In step S63, the second control unit 76 saves the first wearing state and ends the process. For example, the second control unit 76 stores information that the current wearing state is the first wearing state in the second storage unit 78.

[0111] If the second control unit 76 has not received the wearing signal N times in succession in step S62, the second control unit 76 proceeds to step S64. In step S64, the second control unit 76 saves the previous wearing state and ends the process. The second control unit 76 stores, for example, information in the second storage unit 78 that the current wearing state remains the same as the previously saved wearing state.

[0112] If the second control unit 76 has not received a wearing signal from the wearing detection unit 80 in step S61, the second control unit 76 proceeds to step S65. In step S65, the second control unit 76 determines whether the wearing signal has not been received N consecutive times. For example, in the wearing signal reception cycle, the second control unit 76 determines YES in step S65 if the wearing signal has not been received even once since the Nth reception cycle before. For example, in the wearing signal reception cycle, the second control unit 76 determines NO in step S65 if the wearing signal has been received at least once since the Nth reception cycle before. If the determination in step S65 is YES, the second control unit 76 proceeds to step S66.

[0113] In step S66, the second control unit 76 saves the second wearing state and proceeds to step S67. For example, the second control unit 76 stores information that the current wearing state is the second wearing state in the second memory unit 78. In step S67, the second control unit 76 determines whether the head protection device 70 is in a stationary state. If the head protection device 70 is in a stationary state, the second control unit 76 proceeds to step S68. In step S68, the second control unit 76 sets the second control unit 76 to a sleep state and ends the process. If the head protection device 70 is not in a stationary state in step S67, the second control unit 76 does not proceed to step S68 and ends the process.

[0114] If the determination in step S65 is NO, the second control unit 76 proceeds to step S69. In step S69, the second control unit 76 saves the previous wearing state and ends the process. The second control unit 76 stores, for example, information in the second storage unit 78 that the current wearing state remains the previously saved wearing state.
