  For example, when the physical condition of the driver of another vehicle deteriorates, the other vehicle may move unexpectedly and get involved in an accident. It is also possible that a pedestrian whose physical condition has deteriorated strays from the road. The above technique considers only the physical condition of the person in the vehicle and cannot deal with such a case.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a vehicle control system capable of controlling the host vehicle in consideration of the physical condition of a person outside the host vehicle. To do.

  FIG. 1 is a diagram showing a configuration of a vehicle control system according to an embodiment of the present invention. The system includes a medical device 10 (ME) and a portable terminal 20 (PT) that each of the passengers and pedestrians 4 of the vehicles 1 to 3 and an in-vehicle device 30 (VD) mounted on each of the vehicles 1 to 3. It consists of.

  In FIG. 1, assuming that the vehicle 1 is “own vehicle”, a vehicle 2 having the same traveling direction as the own vehicle 1 is referred to as “parallel vehicle”, and a vehicle 3 whose traveling direction is opposite to that of the own vehicle 1 is referred to as “opposing vehicle” " That is, the parallel running vehicle 2 is a vehicle that travels on the own lane side of the road when viewed from the own vehicle 1, and the oncoming vehicle 3 is a vehicle that travels on the opposite lane side of the road when viewed from the own vehicle 1. It is assumed that the pedestrian 4 walks outside the road on which the host vehicle 1 is traveling (referred to as “the sidewalk side”).

  Each of the medical device 10, the portable terminal 20, and the in-vehicle device 30 has a communication function. The medical device 10 performs one-to-one communication with a specific mobile terminal 20 or a specific in-vehicle device 30 that is paired in advance. However, one medical device 10 may be paired with both the specific mobile terminal 20 and the specific in-vehicle device 30. In addition to communication with the specific medical device 10, the mobile terminal 20 and the in-vehicle device 30 can perform broadcast transmission that transmits information to an unspecified number of in-vehicle devices 30.

  As described above, as a wireless communication method having both one-to-one communication and broadcast transmission functions, for example, there is Bluetooth Low Energy (BLE) (“Bluetooth” is a registered trademark). In the present embodiment, communication among the medical device 10, the mobile terminal 20, and the in-vehicle device 30 is assumed to be performed using BLE. A signal transmitted by broadcast in BLE is called a beacon.

  In the present embodiment, the medical device 10 is paired with the portable terminal 20 of the owner (also referred to as “user”) of the medical device 10. That is, the user of the medical device 10 and the user of the mobile terminal 20 paired with the medical device 10 are the same person. Moreover, the medical device 10 shall be paired only with the vehicle-mounted apparatus 30 of the vehicle in which the user of the medical device 10 is boarding. That is, the user of the medical device 10 paired with the in-vehicle device 30 is a passenger of the vehicle in which the in-vehicle device 30 is mounted.

  The medical device 10 measures a user's body temperature, blood pressure, heart rate, and the like, and transmits biometric information that is the measurement result to the user's portable terminal 20 or the in-vehicle device 30 on which the user is aboard. Here, it is assumed that the biological information includes at least one or both of the blood pressure and the pulse rate.

  The mobile terminal 20 adds its own location information to the biometric information received from the medical device 10, and broadcasts the biometric information with the location information added as a beacon. Hereinafter, a beacon including biological information to which position information is added is referred to as a “biological information beacon”. Note that the mobile terminal 20 does not have to be a dedicated device used for communication with the medical device 10 and the in-vehicle device 30, and may be a mobile phone or a smartphone.

  FIG. 2 is a block diagram illustrating a configuration of a main part of the mobile terminal 20. As illustrated in FIG. 2, the mobile terminal 20 includes a communication unit 21, a biological information receiving unit 22, a biological information transmitting unit 23, a current position specifying unit 24, and a position information acquiring unit 25.

  The communication unit 21 communicates with the medical device 10 and the in-vehicle device 30. The biometric information receiving unit 22 receives the biometric information of the user from the medical device 10 of the user paired in advance through the communication unit 21, and sends it to the biometric information transmitting unit 23. The current position specifying unit 24 is, for example, a GPS receiver, and outputs position information that specifies the current position of the mobile terminal 20. The position information acquisition unit 25 acquires the position information output by the current position specifying unit 24 and sends it to the biological information transmission unit 23. The biometric information transmission unit 23 adds the location information acquired by the location information acquisition unit 25 to the biometric information received by the biometric information reception unit 22 to create a biometric information beacon. Broadcast transmission to

  FIG. 3 is a diagram illustrating an example of a data structure of a biological information beacon. The biometric information beacon has a configuration in which the biometric information acquired from the medical device 10 is added with an identifier indicating that the signal is for the vehicle control system according to the present invention and the position information of the mobile terminal 20. . In one biological information beacon, the user of the medical device 10 that has acquired the biological information and the user of the mobile terminal 20 that has acquired the positional information are the same person. Therefore, the biological information beacon includes biological information and position information of the same person.

  Here, the operation of the mobile terminal 20 will be described. FIG. 4 is a flowchart showing the operation of the mobile terminal 20.

  When the portable terminal 20 is activated, the biometric information receiving unit 22 waits for the biometric information of the user transmitted from the specific medical device 10 paired in advance to be received by the communication unit 21 (step S201). When the biological information receiving unit 22 receives biological information from a specific medical device 10 through the communication unit 21 (YES in step S201), the position information acquiring unit 25 acquires position information from the current position specifying unit 24 ( Step S202). The biological information received by the biological information receiving unit 22 and the positional information acquired by the positional information acquiring unit 25 are sent to the biological information transmitting unit 23.

  The biometric information transmission unit 23 creates a biometric information beacon by adding the location information acquired by the location information acquisition unit 25 to the biometric information received by the biometric information reception unit 22 (step S203). Broadcast transmission to the in-vehicle device 30 (step S204). In step S204, the broadcast transmission of the biological information beacon is repeatedly performed a predetermined number of times.

  The biological information receiving unit 22 repeatedly executes the operations in steps S201 to S204 described above.

  Next, the in-vehicle device 30 will be described. FIG. 5 is a diagram illustrating a configuration of the in-vehicle device 30. As shown in FIG. 5, a communication device 301, a current position specifying device 302, an in-vehicle camera 303, an in-vehicle sensor 304, a vehicle control device 305, a display device 306, and an audio output device 307 are connected to the in-vehicle device 30.

  The communication device 301 is for the vehicle-mounted device 30 to communicate with the medical device 10, the portable terminal 20, and the vehicle-mounted device 30 mounted on another vehicle. The communication device 301 may use a general-purpose communication device such as a mobile phone or a smartphone.

  The current position specifying device 302 is a GPS receiver, for example, and outputs position information for specifying the current position of the in-vehicle device 30 (corresponding to the current position of the host vehicle). The current position specifying device 302 may be shared with, for example, a car navigation system.

  The in-vehicle camera 303 is a photographing device that photographs the periphery of the vehicle. The in-vehicle sensor 304 is, for example, a millimeter wave radar or the like, and can detect an obstacle around the vehicle and measure a distance to the obstacle. As the in-vehicle camera 303 and the in-vehicle sensor 304, for example, those used in a vehicle collision prevention system or an automatic driving system may be used.

  The vehicle control device 305 controls vehicle equipment such as an engine, a motor, a brake, a steering, a wiper, and a headlight. The display device 306 is for the vehicle-mounted device 30 to output an image or a text message, and the voice output device 307 is for the vehicle-mounted device 30 to output a warning sound or a voice message. As the display device 306 and the audio output device 307, for example, those of a car navigation system may be used.

  In FIG. 5, an example in which the communication device 301, the current position specifying device 302, the display device 306, and the audio output device 307 are externally attached to the in-vehicle device 30 is shown, but they may be incorporated in the in-vehicle device 30. .

  As shown in FIG. 5, the in-vehicle device 30 includes a biological information receiving unit 31, a biological information transmitting unit 32, a position information acquiring unit 33, a person position determining unit 34, and a vehicle control unit 35.

  The biometric information receiving unit 31 receives the biometric information of the user from a specific medical device 10 paired in advance through the communication device 301 or receives a biometric information beacon broadcast from the mobile terminal 20. The biometric information receiving unit 31 sends the biometric information received from the medical device 10 to the biometric information transmitting unit 32, and sends the biometric information beacon received from the portable terminal 20 to the person position determining unit 34.

  The position information acquisition unit 33 acquires the position information output by the current position specifying device 302 and sends it to the biological information transmission unit 32. The biometric information transmitting unit 32 adds the location information acquired by the location information acquiring unit 33 to the biometric information received from the biometric information receiving unit 31 to create a biometric information beacon, which is used as an unspecified number of in-vehicle devices 30. Broadcast transmission to

  Although the position information acquired by the position information acquisition unit 33 strictly indicates the position of the in-vehicle device 30, the in-vehicle device 30 is paired with the medical device 10 of the user who is on the own vehicle. Therefore, the position of the in-vehicle device 30 can be regarded as the position of the user of the medical device 10.

  Based on the biometric information beacon acquired from the biometric information receiving unit 31, the person position determining unit 34 determines whether the person corresponding to the biometric information is inside or outside the host vehicle. This determination can be made based on, for example, position information extracted from the biological information beacon (that is, position information added to the biological information). For example, from the position information of the in-vehicle device 30 and the position information attached to the biological information, the distance between the in-vehicle device 30 and the person corresponding to the biological information is obtained, and if the distance is greater than a predetermined threshold, It can be determined that the person is outside the host vehicle. The determination may be made based on the reception strength of the biological information beacon (that is, the reception strength of biological information). For example, if the reception intensity of the biometric information beacon is smaller than a predetermined threshold, the biometric information beacon is determined to be transmitted from a device outside the host vehicle (the mobile terminal 20 or other in-vehicle device 30), and It can be determined that the person corresponding to the biological information of the biological information beacon is outside the host vehicle. Further, these two determination methods may be combined.

  In addition, the person position determination unit 34 determines whether the person corresponding to the biological information of the biological information beacon is on the own lane side of the road or the opposite lane side when viewed from the own vehicle from the position information extracted from the biological information beacon. Or whether it is on the sidewalk side. The detailed position of such a person is not only determined based on the position information extracted from the biological information beacon, but is combined with the analysis result of the video captured by the in-vehicle camera 303 or the analysis result of the output of the in-vehicle sensor 304. Therefore, it can be performed with higher accuracy. Conversely, if the accuracy of the position information included in the biological information beacon is sufficiently high, the in-vehicle camera 303 and the in-vehicle sensor 304 may be omitted.

  In the present embodiment, the person position determination unit 34 determines that the person located on the own lane side is likely to be a passenger on a parallel running vehicle, and the person located on the opposite lane side is a passenger on the oncoming vehicle. It is determined that the person on the sidewalk side is likely to be a pedestrian. Whether the person is a passenger or a pedestrian of another vehicle may be determined based only on the position information extracted from the biological information beacon. In addition, the analysis result of the video captured by the in-vehicle camera 303 and the in-vehicle sensor 304 The output analysis result may be taken into consideration. Furthermore, it is possible to take into account the traveling direction and traveling speed of the person, which can be understood from the history of position information.

  The vehicle control unit 35 controls the host vehicle based on the biological information of a person outside the host vehicle. For example, when an abnormality occurs in the biological information of a person outside the host vehicle, the vehicle control device 305 is controlled to fix the seat belt of the host vehicle, reduce the traveling speed, The audio output device 307 is controlled to issue a warning to the inside or outside of the host vehicle.

  Further, the vehicle control unit 35 changes the way of controlling the own vehicle and the way of warning in accordance with the position of the person who has abnormality in the biological information. In the present embodiment, the method of controlling the own vehicle and the way of warning are changed according to whether the person having abnormality in the biological information is located on the own lane side, the opposite lane side, or the sidewalk side. . For example, when a person with an abnormality in biometric information is located on the own lane, the person is likely to be on a parallel running vehicle, and the parallel running vehicle may move unexpectedly. Therefore, the passenger of the own vehicle is warned to that effect, and the vehicle is decelerated by fixing the seat belt. In addition, when a person with an abnormality in biometric information is located on the oncoming lane, the person is likely to be on the oncoming vehicle, and the oncoming vehicle may move unexpectedly. In addition to the above operations, the headlight is switched to a high beam and a horn is sounded to call attention to the oncoming vehicle.

  In the present embodiment, the vehicle control unit 35, when an abnormality occurs in the biometric information of a person outside the host vehicle while the host vehicle is stopped, the presence of a suddenly ill person in the passenger of the host vehicle. A warning is sent to help rescue the suddenly ill.

  Here, the operation of the in-vehicle device 30 will be described. FIG. 6 is a flowchart showing the operation of the in-vehicle device 30.

  When the in-vehicle device 30 is activated, the biometric information receiving unit 31 receives biometric information from a specific paired medical device 10 (a person's medical device 10 in the host vehicle) or in-vehicle of the mobile terminal 20 or another vehicle. It waits for the communication device 301 to receive the biometric information beacon broadcast from the device 30.

  When the biological information receiving unit 31 receives biological information from the specific medical device 10 through the communication device 301 (YES in step S301), the position information acquiring unit 33 acquires position information from the current position specifying device 302 ( Step S302). In this case, the biological information received by the biological information receiving unit 31 and the positional information acquired by the positional information acquiring unit 33 are sent to the biological information transmitting unit 32.

  The biometric information transmitting unit 32 adds the location information acquired by the location information acquiring unit 33 to the biometric information received by the biometric information receiving unit 31 to create a biometric information beacon (step S303). Broadcast to the in-vehicle device 30 (step S304). Broadcast transmission in step S304 is repeated a predetermined number of times.

  Then, it returns to step S301 and waits until the biometric information or biometric information beacon from the medical device 10 is received again. The operations in steps S301 to S304 described above are almost the same as the operations of the mobile terminal 20 shown in FIG. In other words, in the present embodiment, the in-vehicle device 30 has the same function as the mobile terminal 20.

  On the other hand, when the biological information receiving unit 31 receives a broadcasted biological information beacon through the communication device 301 (NO in step S301 and YES in step S305), the person position determination unit 34 becomes the biological information beacon. The position of the person corresponding to the included biometric information is determined (step S306), and it is determined whether the person is inside the host vehicle (step S307).

  If it is determined that the person corresponding to the biological information is inside the host vehicle (YES in step S307), the process returns to step S301 and waits for reception of biological information or a biological information beacon from the medical device 10.

  If it is determined that the person corresponding to the biological information of the biological information beacon is outside the host vehicle (NO in step S307), whether the value of the biological information (blood pressure or heart rate) is within a predetermined normal range By confirming whether or not there is any abnormality in the biological information, it is confirmed (step S308). If there is no abnormality in the biological information of the biological information beacon (YES in step S308), the process returns to step S301.

  If abnormality has occurred in the biological information of the biological information beacon (NO in step S308), the vehicle control unit 35 confirms whether or not the host vehicle is traveling (step S309). If the host vehicle is stopped, the vehicle control unit 35 issues an alarm in the vehicle using the display device 306 and the audio output device 307, thereby notifying the passenger of the host vehicle of the presence of the suddenly ill (step S310). . Then, it returns to step S301.

  If the host vehicle is traveling, the vehicle control unit 35 performs a vehicle control process according to the position of the person whose abnormality has occurred in the biological information (step S311). FIG. 7 is a flowchart showing an example of the vehicle control process.

  In the vehicle control process, the person position determination unit 34 specifies in more detail the position of the person who has an abnormality in the biological information (step S401). That is, the person position determination unit 34 determines whether the person is located on the own lane side, the oncoming lane side, or the sidewalk side of the road on which the host vehicle is traveling.

  When the position of the person is on the own lane side (“own vehicle side” in step S402), the vehicle control unit 35 displays a warning text message on the screen of the display device 306 (step S403), and displays the voice output device 307. And output a warning voice message (step S404). Further, the vehicle control unit 35 controls the vehicle control device 305 to fix the seat belt of the host vehicle (step S405) and decelerate the host vehicle (step S406).

  If the person is on the opposite lane or sidewalk (“opposite lane” or “sidewalk” in step S402), the vehicle control unit 35 displays a warning text message on the screen of the display device 306 (step S402). S407), the voice output device 307 is used to output a warning voice message (step S408). Further, the vehicle control unit 35 controls the vehicle control device 305 to fix the seat belt of the host vehicle (step S409), and switches the headlight of the host vehicle to a high beam (step S410). Further, the vehicle control unit 35 controls the vehicle control device 305 to sound a horn of the host vehicle (step S411) and decelerate the host vehicle (step S412).

  In the example of FIG. 7, the process when the position of the person having the abnormality in the biometric information is the opposite lane and the process when the person is on the sidewalk are the same, but both processes may be different. Good. For example, if the person is on the opposite lane, warning or automatic driving control is performed to guide the vehicle to the lane near the sidewalk. If the person is on the sidewalk, the lane is near the center of the road. It may be possible to perform a warning or automatic operation control to guide the user.

  As described above, in the present embodiment, when an abnormality occurs in the biological information of a person outside the host vehicle, the vehicle control unit 35 is positioned on the own lane side, the opposite lane side, or the sidewalk side. The method of controlling the vehicle and the method of warning are changed depending on whether or not to do so. Therefore, it is possible to perform vehicle control or warning more suitable for the situation, which can contribute to accident prevention.

  According to the vehicle control system according to the present embodiment, since the mobile terminal 20 or the in-vehicle device 30 broadcasts a biometric information beacon including the biometric information of the user of the medical device 10, the in-vehicle device 30 of each vehicle The biometric information of the person outside the vehicle can be acquired. Therefore, the in-vehicle device 30 can control the own vehicle based on the biological information of the person outside the own vehicle, and can prevent an accident caused by the deterioration of the physical condition of the driver or pedestrian of the other vehicle.
