The respective control units (Electronic Control Unit: ECU) are shown.

<Helmet>
The driver J is wearing a full-face type helmet 20. Referring to FIGS. 2 and 3 together, the helmet 20 includes a helmet body 21 that covers the head and the like of the driver J (see FIG. 1), a chin strap portion 30 that is caught on the chin of the driver J, and a driver. And a biological information detection device 40 that detects biological information of J.

  The helmet main body 21 includes a cap body 22 as an outer shell member that covers the head, the jaw, and the neck except the visual field portion, an interior material 23 arranged inside the cap body 22, and an openable / closable visual field portion. The shield 24 is provided.

<Chin strap>
The chin strap portion 30 includes a pair of left and right left chin strap members 31 and a right chin strap member 32, a fixing member 33 that detachably fixes the left chin strap member 31 and the right chin strap member 32, and the length of the chin strap portion 30. And a cord length adjusting unit 38 capable of adjusting the height.

  In the present embodiment, the fixing member 33 is a one-touch buckle. The fixing member 33 includes a socket 34 attached to the lower end of the left jaw string member 31 and a plug 35 attached to the lower end of the right jaw string member 32.

  For example, the left jaw string member 31 and the right jaw string member 32 can be fixed (that is, locked) by inserting the plug 35 into the socket 34 until a click is heard. On the other hand, by pushing the lever 34a of the socket 34 in the direction of the arrow and pulling out the plug 35 from the socket 34, the left jaw string member 31 and the right jaw string member 32 are detached (that is, brought into an unlocked state).

<Biological information detection device>
As shown in FIG. 4, the biological information detection device 40 includes a communication unit 41 that communicates with an external smartphone K (information communication device), a sensor 42 that detects biological information such as a pulse and a blood flow, and a sensor 42. A battery 43 (power source) connected via a switch capable of switching the power supply to the power source. For example, the smartphone K is housed in the clothes of the driver J (see FIG. 1). The detection information from the sensor 42 is input to the control unit 45 (see FIG. 1). The communication unit 41, the sensor 42, and the battery 43 are integrally provided on the same member (for example, substrate). The sensor 42 may be provided on the plug 35 side of the fixing member 33.

  The sensor 42 may be of a contact type or a non-contact type. Further, the sensor 42 may detect alcohol contained in blood, sweat, and exhaled breath, in addition to biological information such as pulse and blood flow.

  For example, the control unit 45 may be mounted on the vehicle side or may be mounted on the smartphone K. The control unit 45 may be mounted only on the smartphone K. For example, the control unit 45 may be installed in the smartphone K by installing the application of the control unit 45 in the smartphone K. Further, using the communication function of the smartphone K (for example, Bluetooth (registered trademark) or the like), the data transmitted from the biological information detecting device 40 is analyzed by the smartphone K, displayed on the screen, and a communication means with the vehicle side is provided. Information may be transmitted to the driver J more reliably by displaying or lighting (blinking) the indicator or the like of the display unit 50 on the vehicle side.

  Instead of mounting the control unit 45 on the smartphone K, the control unit 45 may be mounted only on the vehicle side. Further, depending on the presence / absence of the smartphone K, the function of the control unit 45 may be selectively provided on either the smartphone K side or the vehicle side.

  As shown in FIG. 2, the biological information detecting device 40 is provided on the fixing member 33 of the chin strap portion 30. For example, the biological information detecting device 40 is built in the socket 34.

  The biometric information detection device 40 may be integrated with the portion of the socket 34 on the chin side of the driver J. Thereby, by appropriately adjusting the length of the chin strap portion 30, it is possible to bring the contact state between the biological information detecting device 40 and the chin portion of the driver J into an appropriate state.

  As shown in FIGS. 5 and 6, when the left jaw string member 31 and the right jaw string member 32 are fixed (that is, in a locked state), the biological information detecting device 40 displays the biological information of the driver J. The detection of is started. At this time, the biometric information detection device 40 starts communication with the smartphone K (see FIG. 1). That is, the biological information detection device 40 is configured to recognize the usage state of the helmet 20 when the jaw cord 30 is in the locked state.

  Specifically, when the chin strap portion 30 is in the locked state, the connection between the battery 43 and the sensor 42 is turned on, and power is supplied from the battery 43 to the sensor 42. At this time, the sensor 42 starts to detect the biometric information of the driver J. Then, the communication unit 41 starts communication with the smartphone K.

  On the other hand, the biometric information detection device 40 stops the detection of the biometric information of the driver J when the left jaw cord member 31 and the right jaw cord member 32 are detached (that is, in the unlocked state). At this time, the biological information detecting device 40 stops the communication with the smartphone K. That is, the biological information detecting device 40 is configured to recognize the unused state of the helmet 20 when the jaw cord 30 is in the unlocked state.

  Specifically, when the chin strap portion 30 is in the unlocked state, the connection between the battery 43 and the sensor 42 is turned off, and power is not supplied from the battery 43 to the sensor 42. Therefore, the sensor 42 stops detecting the biometric information of the driver J. At this time, the communication unit 41 stops the communication with the smartphone K.

  Furthermore, in the biological information detecting device 40, when the left jaw cord member 31 and the right jaw cord member 32 are fixed and a predetermined time period during which the biometric information of the driver J is not detected has passed (that is, the lock state is established). However, when the biometric information of the driver J is not detected for a predetermined time), the detection of the biometric information of the driver J is stopped. At this time, the biological information detecting device 40 stops the communication with the smartphone K. That is, the biometric information detection device 40 recognizes the non-use state of the helmet 20 when the biometric information of the driver J is not detected for a predetermined time even if the jaw cord 30 is in the locked state. .

This will be specifically described with reference to the flowchart of FIG.
First, the plug 35 is inserted into the socket 34 (step S1).
In step S2, it is determined whether or not the jaw cord 30 is in the locked state. If “YES” in the step S2, the connection between the battery 43 and the sensor 42 is turned on, and power is supplied from the battery 43 to the sensor 42. That is, the power is turned on, and the process proceeds to step S3. On the other hand, if "NO" in the step S2, the power remains off.

  When the power is turned on, the sensor 42 starts detecting biometric information of the driver J (step S3). At this time, a timer (not shown) also starts timing.

  In step S4, it is determined whether or not a predetermined time has elapsed since the time counting by the timer was started. For example, in step S4, it is determined whether or not the timer has reached a preset time such as 5 minutes or 10 minutes. If "YES" in step S4, the process proceeds to step S5.

  In step S5, it is determined whether the biometric information of the driver J has been detected. If “YES” in step S4, the communication unit 41 starts communication with the smartphone K.

  On the other hand, if "NO" in the step S5, the power is turned off. That is, when the biometric information of the driver J is not detected for the predetermined time, the control unit 45 turns off the power of the sensor 42. Therefore, the sensor 42 stops detecting the biometric information of the driver J. At this time, the communication unit 41 stops the communication with the smartphone K.

  This is based on the assumption that the helmet 20 is being carried by hand while the jaw cord 30 is in the locked state. Further, in the next use, it is considered that the jaw cord portion 30 is once in the unlocked state.

  In addition, when communication with the smartphone K is not performed for a predetermined time even though the chin strap portion 30 is in the locked state, the communication connection with the smartphone K is retried a predetermined number of times, and the communication connection is continued thereafter. When not performed, it may be estimated that the driver J does not carry the smartphone K, and detection of the biometric information of the driver J and communication with the smartphone K may be stopped.

<Warning means>
FIG. 8 shows an example in which a first indicator lamp 57, a second indicator lamp 58 and a third indicator lamp 59 as warning means are arranged on the display unit 50 in which the vehicle speed meter 51, the tachometer 52 and the like of the meter device 17 are arranged. . On the display unit 50, a vehicle speed meter 51 and a tachometer 52 are arranged side by side, and a fuel gauge 53 and a water temperature gauge 54 are arranged on the left and right outside thereof. These are analog types that rotate the pointer to indicate the scale. An indicator lamp group 55 is arranged between the vehicle speed meter 51 and the tachometer 52, and an information display section 56 is arranged above the indicator lamp group 55.

  The meter device 17 is not limited to the one including the analog vehicle speed meter 51 and the tachometer 52, but may be a digital type device for displaying numerical values in characters or increasing or decreasing the length of a bar display in which a plurality of segments are arranged. It may include a vehicle speed meter, a tachometer, and the like.

  The first indicator lamp 57 as a warning means is arranged below the indicator lamp group 55. The second indicator lamp 58 and the third indicator lamp 59 are arranged on the left and right outside of the information display section 56.

  For example, a communication unit (not shown) is provided on the vehicle side, and the display unit 50 receives a signal from the smartphone K (see FIG. 1) and turns on or blinks each indicator lamp 57 to 58 as a warning unit.

For example, the first indicator lamp 57 lights up or blinks when it is recognized that the driver J is tired based on the detection result of the biological information of the driver J, gives a warning to the driver J's visual sense, and is appropriate. Encourage a good break.
For example, the second indicator lamp 58 lights up or blinks when the passenger J is present in addition to the driver J, and the passenger is found to be tired based on the detection result of the biometric information of the passenger. Give a warning to J's vision and call attention.
For example, the third indicator lamp 59 lights up or blinks when the physical abnormality of the driver J is recognized based on the detection result of the biological information of the driver J, gives a warning to the visual sense of the driver J, and provides first aid. Prompt for treatment.

  Note that the tactile sensation of the driver J may be given as a warning. As shown in FIG. 1, the ABS modulator 19 is arranged immediately below the seat surface for the driver J of the seat 14 and is attached to the vehicle body frame 5 and the like. For example, the ABS modulator 19 integrally has a motor for controlling hydraulic pressure, and idlely drives this motor in a state of being separated from the brake system to generate vibration, thereby giving a warning to the tactile sense of the driver J. . The ABS modulator 19 gives priority to the ABS operation when the slip of the wheel is detected. As the means for giving the warning to the driver J by vibration, various oscillators other than the ABS modulator 19 may be used. Furthermore, a warning by sounding or a combination with a visual display may be performed, and the recognition may be further improved by changing the warning interval such as shortening the blinking interval of the indicator lamp.

As described above, the above embodiment includes the helmet main body 21, the chin strap portion 30 that is caught on the chin of the driver J, and the biometric information detection device 40 that detects the biometric information of the driver J. In FIG. 20, the biological information detecting device 40 is provided in the chin strap portion 30.
According to this configuration, since the biological information detecting device 40 is provided in the chin strap portion 30, by tightening the chin strap portion 30 in an appropriate state, the biological information detecting device 40 can be used regardless of the driver J. The contact state with the driver J can be maintained in an appropriate state. In addition, since the shape of the existing helmet is not significantly changed, the movement of the neck of the driver J is not hindered. Therefore, the biometric information of the driver J can be accurately detected without causing the driver J to feel uncomfortable due to the movement of the neck of the driver J and reducing the difference in the contact state due to the individual difference. .

  Further, in the above-described embodiment, the jaw cord portion 30 includes the pair of left and right jaw cord members 31 and right jaw cord members 32, and the fixing member 33 that detachably fixes the left jaw cord member 31 and the right jaw cord member 32. Since the biological information detecting device 40 is provided on the fixing member 33, it is possible to create a sense of unity between the biological information detecting device 40 and the fixing member 33, so that the helmet 20 as a whole is made compact. You can In addition, since the components around the chin strap portion 30 are similar to those of the conventional helmet, it is possible to maintain a good appearance.

  Further, in the above-described embodiment, the biological information detecting device 40 starts detecting the biological information of the driver J when the left jaw string member 31 and the right jaw string member 32 are fixed, so that the jaw string portion 30 is removed. Since the detection of the biometric information of the driver J is automatically started only by locking, the troublesome manual operation becomes unnecessary, and the convenience can be improved.

  Further, in the above-described embodiment, the biological information detecting device 40 stops the detection of the biological information of the driver J when the left jaw cord member 31 and the right jaw cord member 32 are detached, and thus the jaw cord portion 30. Since the detection of the biometric information of the driver J is automatically stopped when the lock is released, the troublesome manual operation is not required and the convenience can be improved. In addition, when the helmet 20 is not used, the biological information detecting device 40 is stopped, so that power consumption can be reduced.

  Further, in the above-described embodiment, the biological information detecting device 40 is operated when the left jaw string member 31 and the right jaw string member 32 are fixed and the time period during which the biological information of the driver J is not detected elapses for a predetermined time. By stopping the detection of the biometric information of the person J, even when it is not necessary to detect the biometric information of the driver J, such as when carrying the helmet 20 with the chin strap 30 locked. Since the detection of the biometric information of the driver J is automatically stopped after the lapse of a predetermined time, a troublesome manual operation is not required and convenience can be improved. In addition, when it is not necessary to detect the biometric information of the driver J, the biometric information detection device 40 stops, so that power consumption can be reduced.

  Further, in the above-described embodiment, since the biological information detection device 40 includes the communication unit 41 that communicates with an external information communication device, data processing can be performed by the external smartphone K. The device 40 can be downsized.

  In the above embodiment, the biological information detecting device 40 further includes the sensor 42 for detecting biological information and the battery 43, and the communication unit 41, the sensor 42, and the battery 43 are integrally provided in the same member. The biological information detecting device 40 can be downsized as compared with the case where the communication unit 41, the sensor 42, and the battery 43 are provided separately and independently.

(Second embodiment)
As shown in FIGS. 9 to 12, in the second embodiment, the communication unit 41 and the sensor 42 are integrally provided on the same member, and the battery 243 is provided on the helmet body 21. In the following description, the same components as those in the first embodiment described above will be designated by the same reference numerals and description thereof will be omitted.

  Specifically, the battery 243 is provided at the center in the left and right of the rear portion of the helmet body 21 and at the lower end portion. As a result, the center of gravity of the helmet 220 can be lowered as compared with the case where the battery 243 is provided above the helmet body 21. In addition, as compared with the case where the battery 243 is provided only on one of the left and right sides of the helmet body 21, it is possible to prevent the center of gravity of the helmet 220 from being biased to the left or right side. In addition, it becomes easier to hold the battery 243 in the neck compared to the case where the battery 243 is provided in the front part of the helmet body 21. Therefore, the fatigue of the driver J during traveling can be reduced.
