  An embodiment of a wearable terminal, a wearable terminal system, and a program according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the wearable terminal system 1 includes a wearable terminal 10 and a vehicle 20.

(Vehicle 20)
The vehicle 20 includes a vehicle control unit 21, a vehicle communication unit 22, a non-contact power feeding device 23, a warning unit 24, a driving operation unit 25, a door lock switch 26b, a start switch 26a, and a door lock device 27. The engine device 29 and the seating sensor 28 are provided.

  The non-contact power feeding device 23 transmits radio waves for charging the wearable terminal 10 to the wearable terminal 10 under the control of the vehicle control unit 21.

  The warning unit 24 performs various warnings to the driver under the control of the vehicle control unit 21 and is configured by a display, a speaker, or a meter.

  The driving operation unit 25 is operated when the vehicle 20 is driven, and includes a shift lever, a steering, or an accelerator pedal.

  The seating sensor 28 detects whether or not the driver is seated in the driver's seat. In this example, the seating sensor 28 includes a pressure sensor that detects pressure applied to the seating surface of the driver's seat.

  The door lock switch 26 b is operated when switching between the locked state and the unlocked state of the door lock device 27, and outputs an operation signal to that effect to the vehicle control unit 21 when operated. The door lock switch 26b is provided on a door handle (not shown) outside the vehicle 20.

  The start switch 26 a is operated when starting the engine device 29 of the vehicle 20, and outputs an operation signal to that effect to the vehicle control unit 21 when operated. The start switch 26a is provided on an instrument panel (not shown) in the vehicle.

  The vehicle communication unit 22 includes an antenna and a transmission / reception circuit, and performs wireless communication with the wearable terminal 10 under the control of the vehicle control unit 21. The vehicle communication unit 22 transmits the vehicle exterior request signal So1 and the vehicle interior request signal So2 under the control of the vehicle control unit 21, and the vehicle exterior response signal Sr1, vehicle interior response signal Sr2, failure determination signal Str, battery remaining amount information signal Sbt, and The biological information signal Sbi is received.

The vehicle control unit 21 includes a memory (not shown) that stores a control program, and a CPU (Central Processing Unit) that executes a driving permission process, a driving process, and the like described later by executing the control program stored in the memory. And).
The vehicle control unit 21 includes, as functions, a driving suitability determination unit 21a, a seating determination unit 21b, and a communication control unit 21c.

The driving suitability determination unit 21a determines whether the health state of the driver wearing the wearable terminal 10 is suitable for driving based on biological information included in a biological information signal Sbi described later received through the vehicle communication unit 22. . For example, the driving suitability determination unit 21a determines that the health state of the driver is suitable for driving when both the blood pressure value and the pulse rate as the biological information are within a preset normal range. The driving suitability determination unit 21a determines that the driver's health condition is not suitable for driving when at least one of the blood pressure value and the pulse rate included in the biological information is outside a preset normal range.
As an example, the normal range of the pulse is set to 60 to 100 times per minute. The normal range of blood pressure is set such that systolic blood pressure is 100 to 140 mmHg and diastolic blood pressure is 60 to 90 mmHg.

  The seating determination unit 21b determines whether the driver is seated in the driver's seat based on the detection result of the seating sensor 28. For example, the seating determination unit 21b determines that the driver is seated in the driver's seat if the pressure on the seating surface detected by the seating sensor 28 is equal to or greater than the threshold, and the driver operates if the pressure is less than the threshold. Determine that you are not seated.

The communication control unit 21 c performs wireless communication with the wearable terminal 10 via the vehicle communication unit 22.
Specifically, as illustrated in FIG. 6, the communication control unit 21 c transmits an out-of-vehicle request signal So1 to the outside of the vehicle via the vehicle communication unit 22 when a driver wearing the wearable terminal 10 is present around the vehicle 20. When the wearable terminal 10 receives the out-of-vehicle request signal So1, the out-of-vehicle response signal Sr1 including an ID (Identification) code is transmitted. When the communication control unit 21c receives this outside response signal Sr1, the communication control unit 21c performs outside checking of the ID code included in the outside response signal Sr1 and the ID code stored in the memory (not shown). When the vehicle control unit 21 receives an operation signal indicating that the door lock switch 26b has been operated when the vehicle outside verification is established, the vehicle control unit 21 switches the door lock device 27 between the locked state and the unlocked state.

As shown in FIG. 7, the communication control unit 21 c transmits an in-vehicle request signal So <b> 2 to the inside of the vehicle via the vehicle communication unit 22 when the driver wearing the wearable terminal 10 gets on the vehicle. When the wearable terminal 10 receives the in-vehicle request signal So2, the wearable terminal 10 transmits the in-vehicle response signal Sr2 including the ID code. When receiving the in-vehicle response signal Sr2, the communication control unit 21c performs in-vehicle collation between the ID code included in the in-vehicle response signal Sr2 and the ID code stored in the memory (not shown). When the vehicle control unit 21 receives an operation signal indicating that the start switch 26a has been operated when the in-vehicle verification is established, the vehicle control unit 21 starts the engine device 29. As a result, the vehicle 20 becomes movable.
Specific processing contents of the other vehicle control unit 21 will be described later with reference to FIGS.

(Wearable terminal 10)
The wearable terminal 10 is a wristwatch type worn on the wrist of the driver and functions as an electronic key.
Specifically, as shown in FIG. 1, the wearable terminal 10 includes a terminal control unit 11, a terminal communication unit 12, a biological information detection unit 13, a battery 15, and a non-contact charging circuit 16.

The biological information detection unit 13 detects a pulse rate and a blood pressure value as biological information of a driver wearing the wearable terminal 10, and outputs the detected biological information to the terminal control unit 11.
Specifically, the biological information detection unit 13 receives a light emitting unit 13a that irradiates near-infrared light toward a human body (radial artery) and reflected light that is not absorbed by hemoglobin in the blood among the irradiated light. A light receiving unit 13b. That is, the biological information detection unit 13 can measure hemoglobin and blood flow by utilizing the property that hemoglobin absorbs light, and can detect a blood pressure value and a pulse rate from the measurement result.

  The battery 15 supplies operating power to each part of the wearable terminal 10.

  The non-contact charging circuit 16 receives power by radio waves from the non-contact power feeding device 23 of the vehicle 20 under the control of the terminal control unit 11 and charges the battery 15 with the received power. The contactless charging method may be any of an electromagnetic induction method, a radio wave reception method, and a resonance method.

  The terminal communication unit 12 includes an antenna and a transmission / reception circuit, and performs wireless communication with the vehicle 20 under the control of the terminal control unit 11. The terminal communication unit 12 transmits the vehicle exterior response signal Sr1, the vehicle interior response signal Sr2, the failure determination signal Str, the battery remaining amount information signal Sbt, and the biological information signal Sbi under the control of the terminal control unit 11, and the vehicle exterior request signal So1 and The in-vehicle request signal So2 is received.

The terminal control unit 11 includes a memory (not shown) that stores a control program, and a CPU (Central Processing Unit) that executes a terminal operation process and the like described later by executing the control program stored in the memory. Prepare.
The terminal control unit 11 includes, as functions, a biological information acquisition unit 11a, a mounting determination unit 11b, a battery remaining amount determination unit 11c, a failure determination unit 11d, and a communication control unit 11e.
The biological information acquisition unit 11a acquires the biological information detected by the biological information detection unit 13.

The wearing determination unit 11b determines whether the driver is wearing the wearable terminal 10 based on the biological information acquired by the biological information acquisition unit 11a.
The wearing determination unit 11b determines that the wearable terminal 10 is not worn when the pulse rate or blood pressure value included in the acquired biological information is a value that cannot be obtained as a human pulse or blood pressure regardless of the health state. The wearing determination unit 11b wears the wearable terminal 10 when the pulse rate or blood pressure value included in the acquired biological information is a value that can be taken as a person's pulse rate or blood pressure value regardless of the health condition. Judgment is made.
The determination of the mounting by the mounting determination unit 11b employs a simpler method than the determination of the propriety of driving by the driving suitability determination unit 21a described above. As an example, as illustrated in FIG. 8, the wearing determination unit 11 b determines that the wearable terminal 10 is worn when one or more pulses are observed within the predetermined time T from the current time tn. On the other hand, the wearing determination unit 11b determines that the wearable terminal 10 is not worn when no pulse is observed within the predetermined time T in the past. The fixed time T is set to a time at which at least one pulse is expected to be observed regardless of the driver's health condition, and is set to about 1 to 2 seconds, for example.
Even if the driver in a health state inappropriate for driving wears the wearable terminal 10, the wearing determination unit 11b determines that the wearable terminal 10 is worn.

  The failure determination unit 11d determines whether or not the wearable terminal 10 has a failure. For example, the failure determination unit 11d monitors the current flowing through the wearable terminal 10 and determines that there is a failure when the wearable terminal 10 is short-circuited or overcurrent.

  The remaining battery level determination unit 11c detects the voltage of the battery 15 and determines the remaining battery level based on the detected voltage.

The communication control unit 11 e performs wireless communication with the wearable terminal 10 via the terminal communication unit 12.
Specifically, the communication control unit 11e wirelessly transmits the biological information signal Sbi including the biological information acquired by the biological information acquisition unit 11a at regular intervals via the terminal communication unit 12. In addition, the communication control unit 11e wirelessly transmits a battery remaining amount information signal Sbt including information related to the remaining battery level determined by the remaining battery level determining unit 11c via the terminal communication unit 12 at regular intervals. . Further, when the failure determination unit 11d determines that the wearable terminal 10 has a failure, the terminal control unit 11 wirelessly transmits a failure determination signal Str indicating that there is a failure via the terminal communication unit 12.
Specific processing contents of the other terminal control unit 11 will be described later with reference to FIGS. 2 and 5.

(Terminal operation processing)
Next, terminal operation processing executed by the terminal control unit 11 will be described with reference to the flowchart of FIG. This terminal operation process is repeatedly executed as long as the voltage of the battery 15 of the wearable terminal 10 is equal to or higher than the operating voltage.

  First, the terminal control unit 11 acquires biometric information detected by the biometric information detection unit 13 via the biometric information acquisition unit 11a (step S101). Then, the terminal control unit 11 determines whether or not the driver is wearing the wearable terminal 10 via the wearing determination unit 11b (step S102).

If the terminal control unit 11 determines that the driver wears the wearable terminal 10 (step S102: YES), the terminal control unit 11 is set to a transmission-permitted state (step S103) and ends the terminal operation process. When the terminal control unit 11 is set to the transmission-permitted state, when receiving the vehicle exterior request signal So1 or the vehicle interior request signal So2, the terminal control unit 11 transmits the vehicle exterior response signal Sr1 or the vehicle interior response signal Sr2 including the ID code stored in the memory.
That is, if the driver wears the wearable terminal 10, the vehicle exterior response signal Sr1 and the vehicle interior response signal Sr2 can be transmitted, and the door lock device 27 can be unlocked and the engine device 29 can be started.

On the other hand, when the terminal control unit 11 determines that the driver does not wear the wearable terminal 10 (step S102: NO), the terminal control unit 11 is set in a transmission prohibited state (step S104), and the terminal operation process is terminated. When the terminal control unit 11 is set to the transmission prohibited state, the terminal control unit 11 does not transmit the vehicle exterior response signal Sr1 or the vehicle interior response signal Sr2 even if the vehicle exterior request signal So1 or the vehicle interior request signal So2 is received.
That is, if the driver does not wear the wearable terminal 10 correctly, the vehicle exterior response signal Sr1 and the vehicle interior response signal Sr2 are not transmitted, whereby the door lock device 27 cannot be unlocked and the engine device 29 cannot be started.

(Driving permit processing)
Next, the driving permission / refusal processing executed by the vehicle control unit 21 will be described with reference to the flowchart of FIG. The driving permission / refusal processing is started when the engine device 29 is started.

  First, the vehicle control unit 21 determines whether or not the driver is seated on the driver's seat via the seating determination unit 21b (step S201). When the vehicle control unit 21 determines that the driver is seated in the driver's seat via the seating determination unit 21b (step S201: YES), the vehicle control unit 21 determines the driver wearing the wearable terminal 10 through the driving suitability determination unit 21a. It is determined whether or not the health condition is suitable for driving (step S202).

  When the vehicle control unit 21 determines that the health state of the driver wearing the wearable terminal 10 is suitable for driving through the driving suitability determination unit 21a (step S202: YES), the vehicle control unit 21 is set to a driving permission state (step S202). S203), the driving permission / rejection processing is terminated. The vehicle control unit 21 validates the operation to the driving operation unit 25 (shift lever, steering, or accelerator pedal) in this driving permission state. Therefore, in this driving permission state, the driver can drive the vehicle 20.

On the other hand, if the vehicle control unit 21 determines that the driver is not seated in the driver's seat (step S201: NO) or determines that the driver's health is not suitable for driving (step S202: NO), The driving prohibition state is set (step S204), and the driving permission / inhibition process is terminated. The vehicle control unit 21 disables or disables the operation on the driving operation unit 25 (shift lever, steering, or accelerator pedal) in the driving prohibited state. Therefore, the driver cannot drive the vehicle 20 in this driving prohibited state.
In this driving prohibition state, the vehicle control unit 21 may disable the operation by locking the shift lever, the steering wheel, or the accelerator pedal so that the shift lever, the steering wheel, or the accelerator pedal cannot be moved. The operation may be invalidated so that the vehicle 20 is not operated regardless of the operation.

(Processing during operation)
Next, a process during driving executed by the vehicle control unit 21 during driving will be described with reference to the flowchart of FIG. The operation process is repeatedly executed during operation, and the operation permission state is set at the start of the operation process.

  First, the vehicle control unit 21 receives the biological information signal Sbi from the wearable terminal 10 via the communication control unit 21c, and acquires the biological information included in the biological information signal Sbi (step S301). The vehicle control unit 21 determines whether or not the driver's health condition is suitable for driving based on the acquired biological information via the driving suitability determination unit 21a (step S302). When the vehicle control unit 21 determines that the health state of the driver is suitable for driving (step S302: YES), the vehicle control unit 21 maintains the driving permission state (step S303) and ends the processing during driving.

  On the other hand, when the vehicle control unit 21 determines that the health condition of the driver is not suitable for driving (step S302: NO), the vehicle control unit 21 determines whether the biological information is correctly detected based on the acquired biological information (step S304). ). For example, it is determined whether or not the biological information is correctly detected based on the presence or absence of a pulse included in the biological information. When the vehicle control unit 21 determines that the biological information is correctly detected (step S304: YES), the vehicle control unit 21 determines that the driver is in poor physical condition (step S305) and prompts the vehicle 20 to stop via the warning unit 24. A warning is given (step S306), and the operation process is terminated. At this time, the vehicle control unit 21 may notify the driver of a coping method for poor physical condition via the warning unit 24.

  On the other hand, if the vehicle control unit 21 determines that the biometric information is not correctly detected (step S304: NO), does the battery remaining amount included in the battery remaining amount information signal Sbt received from the wearable terminal 10 exceed the threshold Th? It is determined whether or not (step S307). The threshold value Th is set based on a battery voltage sufficient for the operation of the wearable terminal 10. When the vehicle control unit 21 determines that the remaining battery level exceeds the threshold Th (step S307: YES), the vehicle control unit 21 determines whether the wearable terminal 10 has a failure according to whether the failure determination signal Str is received from the wearable terminal 10. (Step S308). When the vehicle control unit 21 determines that the wearable terminal 10 has a failure by receiving the failure determination signal Str (step S308: YES), the vehicle control unit 21 issues a warning that prompts the wearable terminal 10 to be repaired via the warning unit 24. (Step S309), the operation process is terminated.

  On the other hand, if the vehicle control unit 21 does not receive the failure determination signal Str and determines that there is no failure in the wearable terminal 10 (step S308: NO), the vehicle control unit 21 assumes that the wearable terminal 10 is not correctly attached (step S310). A warning to prompt the user to wear the correct wearable terminal 10 is given via the warning unit 24 (step S311), and the operation process is terminated.

  On the other hand, when the vehicle control unit 21 determines that the remaining battery level does not exceed the threshold Th (step S307: NO), the vehicle control unit 21 issues a warning that prompts charging of the wearable terminal 10 via the warning unit 24 (step S312). The process during operation is terminated.

(Method of operation)
Next, the operation method of the wearable terminal system 1 by the driver will be described together with the operations of the wearable terminal 10 and the vehicle 20.

  First, as shown in FIGS. 5 and 6, the driver D attaches the wearable terminal 10 to the wrist before getting on the vehicle 20. Then, the wearable terminal 10 enters a transmission permission state by the terminal operation process described above. The driver D approaches the vehicle 20 with the wearable terminal 10 attached. At this time, the outside request signal So1 is periodically transmitted around the vehicle 20. When the wearable terminal 10 (terminal control unit 11) receives the out-of-vehicle request signal So1, the out-of-vehicle response signal Sr1 including the ID code is transmitted. The vehicle 20 (vehicle control unit 21) performs the above-described vehicle exterior verification for the ID code included in the received vehicle exterior response signal Sr1. The driver D pushes and operates the door lock switch 26b in a state in which the vehicle outside verification is established. The vehicle 20 unlocks the door lock device 27 when receiving an operation signal indicating that the door lock switch 26b has been operated in a state where the outside verification is established.

  Next, as shown in FIGS. 5 and 7, the driver D opens the vehicle door, gets on the vehicle 20 and sits on the driver's seat with the wearable terminal 10 mounted. At this time, the in-vehicle request signal So2 is periodically transmitted in the vehicle. When the wearable terminal 10 receives the in-vehicle request signal So2, the wearable terminal 10 transmits an in-vehicle response signal Sr2 including an ID code. The vehicle 20 performs the above-described in-vehicle verification for the ID code included in the received in-vehicle response signal Sr2. In a state where the in-vehicle verification is established, the driver D pushes the start switch 26a. The vehicle 20 starts the engine device 29 when it receives an operation signal indicating that the start switch 26a has been operated in a state where the in-vehicle verification is established. When the engine device 29 of the vehicle 20 is started and the driver D is seated in the driver's seat and the health state of the driver D is suitable for driving, the vehicle 20 enters the driving permission state so that the driver D Can drive the vehicle 20.

(effect)
As mentioned above, according to one Embodiment described, there exist the following effects.

(1) The wearable terminal 10 attached to the driver requests the biometric information acquisition unit 11a that acquires biometric information of the driver wearing the wearable terminal 10 and the vehicle 20 that is an example of a vehicle to control the vehicle 20. A terminal communication unit 12 that transmits response signals Sr1 and Sr2, which are examples of control command signals, and a mounting that determines whether the driver is wearing the wearable terminal 10 based on the biological information acquired by the biological information acquisition unit 11a When the determination unit 11b and the mounting determination unit 11b determine that the driver is wearing the wearable terminal 10, the transmission of the response signals Sr1 and Sr2 through the terminal communication unit 12 is permitted, and the mounting determination unit 11b allows the driver to be wearable. When it is determined that the terminal 10 is not attached, the response signals Sr1, Sr2 through the terminal communication unit 12 It includes a terminal control unit 11 to prohibit transmission, the.
According to this configuration, when the driver does not wear the wearable terminal 10 correctly, for example, when the wearable terminal 10 is held in the driver's hand or when the wearable terminal 10 is stored in a bag or pocket. Since the response signals Sr1 and Sr2 are not transmitted from the wearable terminal 10, the wearable terminal 10 cannot remotely control the vehicle 20. Therefore, it is possible to prompt the driver to wear the wearable terminal 10, and the driver is prevented from forgetting to wear the wearable terminal 10.
Moreover, since the period which can acquire biometric information with the wearable terminal 10 can be lengthened by this, the change of the health state of a driver can be monitored more correctly.
Further, if the driver wears the wearable terminal 10, it is not necessary to carry an electronic key separately, so that convenience can be improved.
Furthermore, since the wearable terminal 10 can determine whether or not the driver wears the wearable terminal 10 based on the biometric information, there is no need to newly provide the wearable terminal 10 with a sensor for detecting whether or not the wearable terminal 10 is worn. The wearable terminal 10 that is required to be downsized can be easily configured.
In addition, because the response signals Sr1 and Sr2 are transmitted, the health condition of the driver based on the biological information is not analyzed, so that the processing burden on the wearable terminal 10 can be reduced.

(2) The terminal control unit 11 transmits the biological information signal Sbi including the biological information acquired by the biological information acquisition unit 11a through the terminal communication unit 12.
According to this configuration, the biological information signal Sbi is transmitted from the wearable terminal 10 to an external device such as the vehicle 20. Therefore, biological information can be monitored in the external device.

(3) The wearable terminal system 1 includes a vehicle 20 in addition to the wearable terminal 10. The vehicle 20 is a wearable terminal based on the vehicle communication unit 22 that is an example of a vehicle communication unit that receives the response signals Sr1, Sr2 and the biological information signal Sbi, and the biological information included in the biological information signal Sbi received through the vehicle communication unit 22. When the response signals Sr1 and Sr2 are received through the vehicle communication unit 22, the door lock device 27 is unlocked. Alternatively, the engine device 29 is started to be in a movable state, and when the driving suitability determination unit 21a determines that the health state is suitable for driving, the driving permission state for permitting driving of the vehicle 20 is set, and the driving suitability determination is performed. A vehicle in a driving prohibited state in which driving of the vehicle 20 is prohibited when it is determined by the part 21a that the health state is not suitable for driving. It includes a vehicle control unit 21 which is an example of a control unit, a.
According to this configuration, the driver can prohibit driving when the health condition is not suitable for driving only by wearing the wearable terminal 10. Thereby, safer driving | operation is realizable.
Moreover, the door lock device 27 can be unlocked and the engine device 29 can be started as long as the wearable terminal 10 is correctly attached, regardless of the health condition of the driver. Therefore, the driver with poor physical condition can get on after the door lock device 27 is unlocked and take a break in the vehicle, or can start the engine device 29 to operate the air conditioner.

(4) The program uses the terminal control unit 11 of the wearable terminal 10, which is an example of a computer, to the biological information acquisition unit (biological information acquisition unit 11 a) that acquires the biological information of the driver wearing the wearable terminal 10 and the vehicle 20. Whether or not the driver wears the wearable terminal 10 based on the biometric information acquired by the terminal communication means (communication control unit 11e) that transmits the response signals Sr1 and Sr2 requesting control of the vehicle 20 and the biometric information acquisition means A mounting determination unit (mounting determination unit 11b) that determines whether the driver is wearing the wearable terminal 10 is permitted to transmit response signals Sr1 and Sr2 through the terminal communication unit. When the means determines that the driver does not wear the wearable terminal 10, the terminal communication means Terminal control means for inhibiting the transmission of the response signal Sr1, Sr2 (terminal control unit 11), to function as a.
By installing the program in the wearable terminal 10, as described above, the driver can be prompted to attach the wearable terminal 10, and the driver is prevented from forgetting to wear the wearable terminal 10.

(Modification)
In addition, the said embodiment can be implemented with the following forms which changed this suitably.

  In the above embodiment, when the wearable terminal 10 is attached to the driver, the door lock device 27 can be unlocked and the engine device 29 can be started through communication with the vehicle 20. However, the control is not limited to audio, car navigation system, air conditioner, seat position, steering position, and the like.

The vehicle 20 is switched between the driving permission state and the driving prohibition state according to the determination result included in the received driving suitability information signal. Moreover, in the said embodiment, although the seating determination part 21b was provided in the vehicle 20, you may be provided in the wearable terminal 10. FIG. In this case, the wearable terminal 10 determines whether or not the driver is seated in the driver's seat based on the signal strength when receiving a radio signal (for example, in-vehicle request signal So2) from the vehicle 20, for example, A seating determination information signal is wirelessly transmitted to the vehicle 20.

  In the above-described embodiment, the vehicle control unit 21 may notify the fact via the warning unit 24 when the driving prohibited state or the driving permitted state is set in steps S203 and S204 of FIG. Further, the vehicle control unit 21 may notify each numerical value of the biological information and / or the remaining battery level via the warning unit 24.

  In the above embodiment, the wearable terminal 10 periodically transmits the battery remaining amount information signal Sbt or the biological information signal Sbi. However, the present invention is not limited to this, and the battery remaining amount information signal Sbt or the biological information signal is transmitted from the vehicle 20. The battery remaining amount information signal Sbt or the biological information signal Sbi may be transmitted only when a request signal for requesting Sbi is received.

  In the above embodiment, the wearable terminal 10 is a type that is worn on the wrist of the driver. However, the wearable terminal 10 is not limited to this as long as it can be worn on the driver's body, and the arm, finger, chest, ankle, foot, leg, It may be one that can be worn on the head or the like. For example, in the case of a glasses-type wearable terminal worn on the head, the iris information of the driver's eyes may be acquired as biometric information. In the case of a ring-type wearable terminal, fingerprint information may be acquired as biometric information.

Any one of the processes in step S201 and step S202 of FIG. 3 in the above embodiment may be omitted. In the driving permission / refusal processing according to FIG. 3, the vehicle control unit 21 may perform personal authentication based on biometric information. In this case, for example, the wearable terminal 10 detects the vein pattern of the wrist and includes the detection result in the biological information signal Sbi. The vehicle control unit 21 may perform pattern matching between the vein pattern included in the received biological information signal Sbi and the vein pattern of the driver stored in advance, and may switch to the driving permission state on condition that the pattern matching is established. Thereby, it is suppressed that persons other than a regular driver wear the wearable terminal 10, and drive the vehicle 20 illegally. The personal authentication is not limited to vein pattern matching but may be biometric authentication such as fingerprint authentication or iris authentication.
