Description

Technical Field

[0001] This invention relates to a helmet and a two-wheeled vehicle safety driving system.

Background Art

[0002] Regarding safety measures for two-wheeled vehicle driving, the first thing that comes to mind is a helmet. With the implementation of the revised Road Traffic Law, it has become an obligation to encourage bicycle users to wear helmets, and it is necessary to wear a helmet when driving a wide range of two-wheeled vehicles including motorcycles. For bicycles, although it has become an obligation to encourage wearing a helmet when getting on, it still takes some effort to wear it. Also, if the chin strap is not firmly attached and locked, the risk during a fall or accident increases. Furthermore, since it has been very troublesome to wear a helmet that has not been mandatory until now, there have been problems such as not actually wearing it even though one has it, or not wearing it correctly.

[0003] Regarding safety measures for two-wheeled vehicle driving, secondly, there are problems related to the lighting of the lights. Especially in the case of bicycles, there are currently many accidents caused by driving without lights when it is getting dark in the evening. Also, the lighting by two-wheeled vehicles has the problem of being difficult to notice because its height is limited to a certain level or below.

[0004] Patent Document 1 discloses a technique using radio waves between a two-wheeled motor vehicle and a helmet (see, for example, FIG. 1). Specifically, when driving a two-wheeled motor vehicle, it is obligatory to wear a helmet, and this helmet is required to meet certain standards for protecting the driver's head. Therefore, in this technique, the identification signal of the helmet is compared with the identification signal stored in the vehicle to determine whether to permit the engine to start.

[0005] The first invention of Patent Document 2 includes an engine that generates driving force for a two-wheeled vehicle, protective gear such as a helmet that a driver boarding the vehicle body holding the engine should wear, electric field generating means built into the protective gear that applies an electric field to the body of the driver wearing the protective gear, electric field detecting means built into the vehicle body that detects the electric field applied to the body of the driver, and control means that starts the engine only when the electric field detecting means detects the electric field by the electric field generating means while the engine is stopped.

[0006] The electric field detecting means in the invention described in this Patent Document 2 is built into the vehicle body and detects the electric field applied to the body of the driver. And the control means starts the engine only when the electric field detecting means detects the electric field by the electric field generating means while the engine is stopped, that is, only when the driver wearing the protective gear touches the vehicle body. Thus, even if a driver not wearing the protective gear touches the vehicle body, since no electric field is generated by the electric field generating means, the engine does not start. Also, even if the driver wears the protective gear, if this driver does not touch the vehicle body, since no electric field is detected by the electric field detecting means, the engine also does not start.

[0007] The second invention described in Patent Document 2, in the configuration of the first invention, the electric field generating means has first storage means for storing a unique identification signal, while the control means has second storage means for storing the same identification signal as the unique identification signal. The electric field generating means modulates the unique identification signal and applies an electric field to the body of the driver, and the control means starts the engine when the same identification signal as the identification signal stored in the second storage means is obtained as a result of the electric field detecting means detecting and demodulating the electric field by the electric field generating means.

[0008] According to the second invention disclosed in Patent Document 2, in addition to the operation of the first invention, the protective device itself serves as an authentication key, and the control means collates the received identification signal with the stored identification signal, and starts the engine when it is determined that the received identification signal is a legitimate identification signal. Therefore, keyless engine start becomes possible. Also, since there is no loss of a dedicated metal key, the convenience for the driver is improved.

[0009] According to the third invention disclosed in Patent Document 2, in the configuration of the first and second inventions, the protective device has a switch for the electric field generating means to apply an electric field to the driver's body. According to this third invention, in addition to the operations of the first and second inventions, the electric field generating means applies an electric field to the driver's body triggered by the ON operation of the switch, so the power consumption of the electric field generating means can be suppressed compared to the case where an electric field is constantly applied to the driver's body.

[0010] Patent Document 3 discloses a control device for a motor, an electric lock mechanism, and an electric vehicle equipped with an electric lock mechanism, which have a highly convenient electric lock function while maintaining the anti-theft effect. In this invention, the control device of the motor of the electric assist bicycle assists in the propulsion or running of the electric assist bicycle. The control device used includes a receiving unit capable of receiving communication signals that can be transmitted and received by human body communication from a plurality of signal receiving units, and a control unit that detects the reception of the communication signal and generates and outputs a drive signal for the motor. The control unit controls the rotation of the motor in response to the detection of the reception of the communication signal.

[0011] Patent Document 4 discloses a wearable terminal device capable of reducing the frequency of power source maintenance. This device includes a wearing part worn by the user, a contact terminal device that contacts the user, a wearing communication part that performs human body communication via the user, a wearing storage part that stores authentication information used by the contact terminal device for user authentication, a wearing control part that controls the human body communication by the wearing communication part to transmit the authentication information to the contact terminal device by human body communication, and an ambient power generation part that generates power using at least part of the power used for human body communication from the energy in the environment.

[0012] In the invention of Patent Document 4 as described above, the environmental power generation unit provided in the contact terminal device generates the power necessary for human body communication in the contact terminal device. Therefore, compared with the configuration in which the contact terminal device does not include the environmental power generation unit, since it is not necessary to replace or charge the power source required for the contact terminal device, the frequency of power source maintenance can be reduced.

[0013] Patent Document 5 discloses a method for detecting or detecting without misjudgment or malfunction whether an object to be worn such as a predetermined uniform, helmet, glove, etc. is worn on the body, and a safety system applying this method. The method of this invention arranges a transmitter and a receiver using the body as a communication path on an object to be worn on the body such as a uniform or a helmet, and when the object is properly worn on the body, the transmitter and the receiver communicate with each other through the body, and it is detected based on the reception state of the receiver whether the object is not worn on the body or is not properly worn.

Embodiments for Carrying Out the Invention

[0027] Hereinafter, with reference to the accompanying drawings, a helmet and a two-wheeled vehicle safe driving system according to embodiments of the present invention will be provided. In each figure, the same reference numerals are assigned to the same components, and redundant explanations are omitted. The helmet according to the first embodiment of the present invention will be described with reference to FIG. 1. This helmet has a cap portion 1 that covers the head. The cap portion 1 or an accessory of the cap portion 1 is provided with a safety device for protecting safety.

[0028] In the present embodiment, the accessory of the cap portion 1 is a chin strap 2 that extends from the cap portion 1 to the chin. The safety device is a chin strap mounting device 3 that fixes the chin strap 2 in a mounted state.

[0029] As shown in FIGS. 2 and 3 for example, the jaw strap mounting device 3 has a structure in which an insertion portion 31 provided at one end of the jaw strap 2 and a receiving portion 32 provided at the other end of the jaw strap 2 are fitted together. The tip of the insertion portion 31 has a structure in which a hammer-shaped overhanging portion 34 is provided on a thin base portion 33. The receiving portion 32 is provided on an extended wide base 35 of the jaw strap 2 such that two elastic L-shaped portions 36 face each other. The receiving portion 32 is placed in a housing 37, and as shown in FIG. 2, the insertion portion 31 is inserted into the housing 37 to effect the connection.

[0030] The housing 37 is provided with two locking mechanisms 40 shown in FIG. 3, and it is possible to lock with the overhanging portion 34 in the gap 38 formed by the two L-shaped portions 36. That is, the locking mechanism 40 is constituted by a magnetically fixed movable piece 42 that moves in and out of the electromagnet portion 41. In the unlocked state, the electromagnet portion 41 is not energized and the movable piece 42 is in a hidden state. At this time, by moving the housing 37 as shown by the arrow in FIG. 2, the two L-shaped portions 36 can be elastically separated and returned, enabling free connection and disconnection. On the other hand, when it is in the locked state, the electromagnet portion 41 is energized, causing the movable piece 42 to pop out and press the tips of the two L-shaped portions 36, realizing a fixed state where the overhanging portion 34 does not move.

[0031] Inside the cap portion 1, a body communication electrode 4, a body communication section 5, and a safety device control section 6 are provided. The body communication electrode 4 serves as an electrode for body communication that is performed via the body of a person wearing the cap portion 1. The body communication section 5 receives at least signals via the body communication electrode 4 by body communication. The safety device control section 6 controls the safety device (here, the jaw strap mounting device 3) based on the content information of the signals received via the body communication section 5.

[0032] The human body communication electrode 4, the human body communication unit 5, the safety device control unit 6, and the safety device (here, the jaw strap wearing device 3) can be configured using a computer as shown in FIG. 4. That is, the CPU 100 controls each part using the programs in the main memory 110 and the program memory 111. The drive interface 113 and the communication interface 114 are connected to the CPU 100 via the bus 112.

[0033] The jaw strap wearing control unit 13 is connected to the drive interface 113, and the human body communication unit 5 is connected to the communication interface 114. The CPU 100 controls the jaw strap wearing control unit 13 via the drive interface 113 and controls the human body communication unit 5 via the communication interface 114.

[0034] A two-wheeler safe driving system can be configured using the helmet of the first embodiment having the above configuration. FIG. 5 shows a bicycle which is a two-wheeler used in the first embodiment of the two-wheeler safe driving system. On the handlebar of this bicycle, a two-wheeler side human body communication electrode 61 is provided, on the saddle, a two-wheeler side human body communication electrode 62 is provided, and on the pedal, a two-wheeler side human body communication electrode 63 is provided. A two-wheeler side human body communication unit 60 is provided on the bicycle. The two-wheeler side human body communication unit 60 only needs to be attached to the two-wheeler, and its installation location is not limited. The two-wheeler side human body communication unit 60 communicates the drivable information indicating that a person can drive this two-wheeler via the two-wheeler side human body communication electrodes 61 (62, 63).

[0035] FIG. 6 shows the operating state of the first embodiment of the two-wheeler safe driving system. The two-wheeler side human body communication unit 60 of the bicycle transmits a signal of drivable information indicating that a person can drive this two-wheeler. This signal reaches the two-wheeler side human body communication electrodes 61 (62, 63) via each part of the bicycle, and from these two-wheeler side human body communication electrodes 61 (62, 63), it reaches the helmet H according to the first embodiment by human body communication via the human body P, and is received by the human body communication unit 5 via the human body communication electrode 4. The safety device control unit 6 shown in FIG. 4 takes in the above information from the human body communication unit 5.

[0036] The safety device control unit 6 configured by the computer shown in FIG. 4 operates according to a program corresponding to the flowchart shown in FIG. 7, and thus will be described. The CPU 100 monitors whether the drivable information has arrived (S11). As shown in FIG. 6, the two-wheeled vehicle side body communication unit 60 of the bicycle transmits a signal of the drivable information indicating that a person can drive this two-wheeled vehicle, and this signal reaches the two-wheeled vehicle side body communication electrodes 61 (62, 63) through each part of the bicycle, and from this two-wheeled vehicle side body communication electrode 61 (62, 63), it reaches the helmet H according to the first embodiment through the human body P by body communication, and is received by the body communication unit 5 through the body communication electrode 4. As a result, the process branches to YES in step S11, and the CPU 100 controls the jaw strap mounting device 3 to realize the locked state (S12).

[0037] Next, the CPU 100 monitors whether the drivable information has stopped for a predetermined time (S13). When a person releases their hand from the handlebar, their foot from the pedal, and gets off the saddle, the signal to the human body P stops. If this situation continues for a predetermined time, the process branches to YES in step S13, and the CPU 100 controls the jaw strap mounting device 3 to realize the unlocked state (S14). As a result, the person can remove the helmet by removing the jaw strap 2. In this flowchart, the unlocking is realized on the condition that the drivable information has stopped for a predetermined time. Instead of this, or together with this process, a unlocking button or the like may be provided on the bicycle, and when this button is operated, the two-wheeled vehicle side body communication unit 60 receives this and transmits a signal related to the unlocking instruction information. In this case, when the signal related to the unlocking instruction information is transmitted to the helmet side by body communication, the unlocking is realized.

[0038] FIG. 8 shows a helmet according to the second embodiment. In this embodiment, the safety device is the lighting device 7 that illuminates with light, and the safety device control unit is the lighting device control unit 8 that controls the on / off of the light of the lighting device 7. The safety device (here, the lighting device 7) of this embodiment can be configured using a computer as shown in FIG. 9. That is, the lighting device control unit 8 is used instead of the jaw strap wearing device 3 in the first embodiment shown in FIG. 4. The configuration of the bicycle, which is a two-wheeled vehicle, is the same as that of the first embodiment.

[0039] FIG. 10 is a flowchart showing the operation of the two-wheeled vehicle safety driving system according to the second embodiment. This will be described. The CPU 100 monitors whether the drivable information has arrived (S21). As shown in FIG. 6, the two-wheeled vehicle side human body communication unit 60 of the bicycle transmits a signal of drivable information indicating that a person can drive this two-wheeled vehicle, and this signal reaches the two-wheeled vehicle side human body communication electrodes 61(62, 63) through each part of the bicycle, and from this two-wheeled vehicle side human body communication electrode 61(62, 63), it reaches the helmet H according to the first embodiment through the human body P by human body communication, and is received by the human body communication unit 5 through the human body communication electrode 4. As a result, the process branches to YES in step S21, and the CPU 100 controls the lighting device control unit 8 to control the lighting device 7 to realize the light-on state (S22).

[0040] Next, the CPU 100 monitors whether the drivable information has stopped for a predetermined time (S23). When a person releases their hand from the handlebar, their foot from the pedal, and gets off the saddle, the signal to the human body P stops. If this situation continues for a predetermined time, the process branches to YES in step S23, and the CPU 100 controls the lighting device 7 to realize the light-off state (S24). As described above, the lighting device 7 can surely realize the lighting of the light during driving.

[0041] FIG. 11 shows a helmet according to a third embodiment. The helmet according to this third embodiment is generally the same as the configuration of the helmet according to the above-described first embodiment. The safety device control unit 6A of the present embodiment controls the chin strap mounting device 3 to realize not only the locked state or the unlocked state, but also controls to transmit a signal of information on the chin strap state including the fixed lock and the fixed release from the body communication unit. The body communication unit 5A receives and transmits signals by body communication via the body communication electrode 4 described above.

[0042] FIG. 12 shows the configuration of a bicycle used in a two-wheeled vehicle safety driving system according to the third embodiment. This bicycle is substantially the same as the configuration of the bicycle of the first embodiment. The bicycle of the present embodiment includes a brake lock mechanism 70 that locks the wheels of the two-wheeled vehicle in a non-rotatable state. Actually, the brake lock mechanism 70 is composed of a brake handle, a front brake and a rear brake (not shown), and a transmission mechanism such as a wire that connects these to the brake handle. Here, the portion of the brake handle is shown as the brake lock mechanism 70.

[0043] Furthermore, the bicycle of the present embodiment includes a brake lock mechanism control means 80. The brake lock mechanism control means 80 controls the brake lock mechanism based on the information on the fixed lock and the fixed release of the chin strap mounting device obtained via the two-wheeled vehicle side body communication unit 60 to make the wheels of the two-wheeled vehicle in a rotatable / non-rotatable state.

[0044] The control unit including the brake lock mechanism control means 80 in the bicycle of the present embodiment can be configured using a computer as shown in FIG. 13. That is, the CPU 200 controls each part using programs in the main memory 210 and the program memory 211. A drive interface 213 and a communication interface 214 are connected to the CPU 200 via a bus 212.

[0045] The brake lock mechanism control means 80 is connected to the drive interface 213, and the two-wheeler side human body communication section 60 is connected to the communication interface 214. The CPU 200 controls the brake lock mechanism control means 80 via the drive interface 213 and controls the two-wheeler side human body communication section 60 via the communication interface 214.

[0046] In this embodiment, when a person gets on a bicycle, on the helmet side, the operation of the first embodiment already described is performed, and the chin strap locked state is realized. In the helmet, the safety device control section 6A controls the human body communication section 5A to transmit a signal of information related to the fixed locked chin strap state. The human body communication section 5A transmits the signal of the information by human body communication via the human body communication electrode 4. The operation of the bicycle in the present embodiment hereafter will be described with reference to the flowchart shown in FIG. 14.

[0047] The CPU 200 waits for the arrival of the chin strap lock information (S31). When the chin strap lock information arrives, it branches to YES in step S31, and controls the brake lock mechanism 70 to realize the unlocked state (S32). Next, the CPU 200 monitors whether the chin strap unlock information has arrived (S33). When the information arrives and branches to YES in step S33, it controls the brake lock mechanism 70 to realize the locked state (S34). Thus, before getting on the bicycle, it is in the brake locked state, but when getting on the bicycle, the chin strap is locked and fixed, and subsequently the brake lock of the bicycle is released. Thereby, when the chin strap of the helmet is locked and fixed to ensure safety, it becomes possible to run the bicycle, and further safety is ensured. In FIG. 14, in addition to monitoring whether the chin strap unlock information has arrived in step S33, it can be configured to monitor whether the continuous arrival of the chin strap lock information has stopped, and when this condition is satisfied, proceed to step S34.

[0048] That is, since the jaw strap mounting device 3 is unlocked when a person gets off the bicycle, it is conceivable that the two-wheeler side human body communication unit 60 cannot receive the jaw strap unlocking information by human body communication. Therefore, after the jaw strap mounting device of the helmet 3 is locked and fixed, the jaw strap lock information is continuously transmitted at a required time interval, and when the human body communication is interrupted after the person gets off the bicycle, the brake lock state is realized. Thus, even though it has a mechanism for manually realizing the brake lock state, it is suitable when, for example, one forgets to set the brake to the locked state.

[0049] FIG. 15 shows a helmet according to a fourth embodiment. The helmet includes a storage battery 9 and a charging processing unit 9A that supply power to a lighting device 7, which is a safety device control unit. The charging processing unit 9A receives a signal via the human body communication electrode 4, generates electric power based on this signal, and charges the storage battery 9 with the generated electric power. The safety device (here, the lighting device 7) of the present embodiment can have a configuration using a computer as shown in FIG. 16. In this configuration, it is basically the same as that of the safety device in the helmet of the second embodiment. A power interface 115 is connected to a bus 112 extending from the CPU 100, and the charging processing unit 9A is connected to this power interface 115. The CPU 100 controls the charging processing unit 9A via the power interface 115 to charge the storage battery 9.

[0050] FIG. 17 shows the configuration of a bicycle used in a two-wheeler safe driving system according to the fourth embodiment. The configuration of the bicycle according to this embodiment is basically the same as that of the bicycle in the second embodiment. The bicycle according to this embodiment is different from the second embodiment in that it includes a power generation device 90 that generates electricity in response to the rotation of the wheels and a power transmission control unit 95. The power transmission control unit 95 superimposes a signal on the waveform of the electric power generated by the power generation device 90 and causes it to be transmitted from the two-wheeler side human body communication unit 60. Further, this bicycle is provided with a lighting device 96, and the lighting device 96 can be lit and the bicycle can run using the electric power generated by the power generation device 90.

[0051] Fig. 18 shows a flowchart of the operation by the power transmission control unit 95, Fig. 19 shows a flowchart of the operation by the charging processing unit 9A, and these operations will be described. The power transmission control unit 95 detects whether or not power is being generated by the power generation device (S41). When it is detected that power is being generated, a signal of the information to be transmitted is superimposed on the waveform related to power generation and transmitted from the two-wheeler side human body communication unit 60 (S42). The process of "superimposing a signal of the information to be transmitted on the waveform related to power generation" can be realized, for example, by modulating the waveform of power generation with the signal of the information to be transmitted as a carrier wave and then transmitting it.

[0052] On the other hand, the charging processing unit 9A has detected the arrival of the drivable information (S51), and when branching to YES in this step 51, extracts the carrier wave of the signal of the arrived information and generates power (S51). Further, the generated power is used to charge the storage battery 9 (S52).

[0053] The two-wheeler safe driving system according to the fifth embodiment includes an electric assist mechanism that performs electric assist to rotate the wheels electrically, adopts a configuration basically the same as that of the two-wheeler safe driving system according to the third embodiment, and is configured such that the electric assist by the electric assist mechanism can be performed only when the wheels of the two-wheeler are made rotatable by the brake lock mechanism control means 80.
