[First Embodiment]
[Configuration of First Embodiment]
The abnormality notification system 1 to which the present invention is applied counts the number of terminal devices such as smartphones when the running state satisfies the counting condition, and includes the number of terminal devices when a vehicle abnormality such as an accident occurs. It has a function of notifying information to the outside of the vehicle. In this specification, a portable device that is a device such as the smartphone 20 used by a user is referred to as a terminal device or a terminal.

  As shown in FIG. 1, the abnormality notification system 1 includes a number-of-people detection ECU 10 mounted on a vehicle 100 and one or a plurality of smartphones 20 mainly carried in the vehicle 100 by occupants of the vehicle 100. Have been. The number-of-heads detection ECU 10 and the smartphone 20 are set to communicate with each other by Bluetooth (registered trademark).

  The vehicle 100 includes a moving distance detecting unit 31, a GPS (Global Positioning System) receiver 32, a traveling speed detecting unit 34, and an emergency communication unit 35, in addition to the number of people detecting ECU 10. The number-of-people detection ECU 10, the moving distance detection unit 31, and the emergency communication unit 35 are communicably connected to each other via a communication bus 5.

  The number detection ECU 10 includes a CPU 11, a memory 12 such as a ROM and a RAM, and a BLE (Bluetooth Low Energy) module 13. The CPU 11 and the memory 12 constitute a known computer, and the CPU 11 performs various processes such as an on-vehicle device process, which will be described later, according to a program stored in the memory 12. In the in-vehicle device processing, information on the number of persons riding the vehicle 100 is sent to the emergency communication unit 35.

  Further, in the memory 12, identification information for identifying a terminal device such as the smartphone 20 possessed by a person who has a possibility of getting on the vehicle 100 is recorded in advance as registration information. The registration information is used in on-vehicle device processing described later.

  The BLE module 13 is a well-known module that performs Bluetooth communication using a communication method with reduced power. The BLE module 13 is set so that the inside of the vehicle 100 becomes a communicable area, and mainly communicates with the smartphone 20 carried by the occupant of the vehicle 100.

  The GPS receiver 32 is configured as a well-known position detecting device that detects a position based on radio waves transmitted from GPS satellites. The GPS receiver 32 repeatedly sends the detected position to the moving distance detecting unit 31.

  The traveling speed detection unit 34 is configured as a known vehicle speed sensor that detects the traveling speed of the vehicle 100. The traveling speed detection unit 34 repeatedly detects the vehicle speed and sends the detected vehicle speed to the moving distance detection unit 31.

  The moving distance detection unit 31 periodically calculates the moving distance of the vehicle 100 and outputs the obtained moving distance (for example, the total traveling distance of the vehicle 100) to the bus 5. For example, the moving distance detection unit 31 outputs, as the moving distance, the integrated value of the deviation of the position repeatedly obtained from the GPS receiver 32. Alternatively, the moving distance detecting unit 31 multiplies the vehicle speed obtained from the traveling speed detecting unit 34 by time and integrates the output, and outputs the result as the moving distance.

  The Bluetooth module 24 is configured as a known Bluetooth module. The Bluetooth module 24 communicates with the number-of-heads detection ECU 10 using Bluetooth. That is, the Bluetooth module 24 also has a BLE communication function, and is configured to be able to communicate with the BLE module 13 of the number-of-people detection ECU 10.

[Process of First Embodiment]
In the abnormality notification system 1 configured as above, the number-of-people detection ECU 10 performs the on-vehicle device processing shown in FIG. In addition, the smartphone 20 performs the smartphone processing illustrated in FIG.

  The in-vehicle device process and the smartphone process are processes for detecting the number of occupants of the vehicle 100. The on-vehicle device process is a process that is started, for example, when the power of the vehicle (a switch such as an ignition switch) is turned on, and the smartphone process is a process that is started, for example, when the power of the smartphone 20 is turned on. .

  In the in-vehicle device processing, as shown in FIG. 2, first, the BLE module 13 is activated, and a terminal device such as the smartphone 20 located around (within the communicable range) is searched (S110). On the other hand, the smartphone 20 performs the smartphone process illustrated in FIG. 3, and in this process, determines whether it is time to transmit a signal indicating the presence of the own device to the surroundings (S210). If it is not the timing to transmit the signal (S210: NO), the process of S210 is repeated.

If it is time to transmit a signal (S210: YES), an Advertising packet indicating the presence of the own device is transmitted to the surroundings (S220), and the process returns to S210.
In the on-vehicle device processing, such an advertising packet is received from a terminal device located in the vicinity, and as shown in FIG. 2, the number of detected terminal devices is recognized (S120). Note that the Advertising packet also includes identification information (ID) for specifying the terminal device. When recognizing the number of detected terminal devices, this identification information is also acquired, and the information is stored in the memory 12. Record.

  Subsequently, the number of times of execution of the processing since the start of the on-vehicle device processing is set as the number of detections n, and the number of detections n is compared with a preset threshold N (S130). Here, the number-of-times threshold N is a value set in order to exclude the terminal device located outside the vehicle 100 that has been detected by chance from the number of detected terminals, and is set to a value of about 2 to 5, for example.

  If the number of detections n is equal to or smaller than the number threshold N (S130: NO), the process proceeds to S160 described later. In other words, when the number of detections n is equal to or less than the threshold value N, there is a high possibility that the detection accuracy of the number of terminal devices is low, so that the process of determining the number of detected terminals is omitted.

  If the number of detections n exceeds the number threshold N (S130: YES), the registration information is acquired from the memory 12 (S132). The registration information includes identification information for identifying a registered terminal which is a terminal device registered in advance, and information indicating characteristics (gender, age, presence / absence of chronic illness, etc.) of a person possessing the terminal device.

Subsequently, the packet other than the registered terminal is removed from the obtained Advertising packet (S134). That is, the number of detected terminals and the identification information of the registered terminal are left.
Subsequently, those whose detection rate is equal to or greater than the detection threshold are extracted, and the number of extracted ones is set as the number of detected notifications (S140). With this configuration, it is easy to detect a terminal device whose radio wave intensity is constant and high (a terminal device whose change in radio wave intensity is small). Here, the detection rate indicates the probability of detecting a certain terminal device with respect to the number of detections n, and is a value obtained for each terminal device.

  Further, the detection threshold is a value set to exclude a terminal device located outside the vehicle 100 that has been detected by chance, similarly to the count threshold N. The detection threshold is set to, for example, a value of about 50%. The number of detected notifications is a number for notifying another ECU of the number of detected terminal devices.

  Subsequently, the moving distance is acquired from the moving distance detecting unit 31 (S160). Then, it is determined whether or not the moving distance is equal to or longer than the reference distance (S170). The distance acquired in the processing of S160 is information such as the total traveling distance, but the moving distance used in the processing of S170 is the distance after performing the processing of S110 to S150.

  That is, at the start of this processing, the moving distance is acquired from the moving distance detecting unit 31, and the difference between this distance and the moving distance acquired in the processing of S160 is used in the processing of S170. In the configuration of the present embodiment, a process of detecting the number of people is performed after the vehicle 100 moves by the moving distance and before the movement (before the vehicle 100 starts moving).

  If the moving distance is shorter than the reference distance (S170: NO), the process returns to S160. If the moving distance is equal to or longer than the reference distance (S170: YES), the processing from S110 is repeated.

  Next, an emergency communication process performed by the emergency communication unit 35 will be described. The emergency communication process is a process of notifying the cloud 36 of information such as the number of persons riding the vehicle 100 when the vehicle 100 is abnormal.

  In the emergency communication process, as shown in FIG. 4, first, the bus 5 is monitored, and it is determined whether or not the number of detected notifications has been received (S250). If the number of detected notifications has not been received (S250: NO), the process of S250 is repeated.

  If the number of detected notifications has been received (S250: YES), the received data is held in the memory in the emergency communication unit 35 (S260). Subsequently, it is determined whether an abnormality has occurred in the vehicle 100 (S270). When an abnormality is detected, for example, when a large acceleration that may cause an accident is detected, or when an occupant of the vehicle 100 does not move, the event is recognized by a known method (eg, image recognition using an acceleration sensor or a camera). When these events are detected, it is determined that the event is abnormal.

  If no abnormality has occurred in vehicle 100 (S270: NO), the process of S270 is repeated. If an abnormality has occurred in vehicle 100 (S270: YES), abnormality information indicating that there is an abnormality in a person in the vehicle is sent to a predetermined server (emergency call center, etc.) located on cloud 36 (S280). . At this time, the number of persons to be rescued is specified based on the information on the number of persons sent from the number-of- persons detection ECU 10, and the fact that an abnormality has occurred is sent to the cloud 36 together with the number of persons as abnormality information.

  In the present embodiment, the number-of-people detection ECU 10 also acquires information indicating the characteristics (gender, age, presence / absence of chronic illness, etc.) of the person holding the terminal device, and transmits this information to the emergency communication unit 35 as registration information. . Then, the emergency communication unit 35 is set to send the registration information to the cloud 36 together with the number of people.

When such processing ends, the emergency notification processing ends.
[Effects of First Embodiment]
In the abnormality notification system 1 described above, the number-of-people detection ECU 10 acquires the running state of the vehicle and, when the running state of the vehicle satisfies a preset count condition, one or more terminals each of which is a device possessed by a person.

In addition, in the above-described abnormality notification system 1, the number-of-person detection ECU 10 counts the number of terminal devices even when the count condition is satisfied before the vehicle starts running.
According to such an abnormality notification system 1, since the number of terminal devices can be counted a plurality of times, the detection accuracy of the number of persons can be improved. Further, according to such an abnormality notification system 1, since the number of terminal devices is counted before and after the start of traveling of the vehicle, detection accuracy of the number of persons can be improved.

  In the abnormality notification system 1 described above, when counting the number of terminal devices, the number-of-people detection ECU 10 acquires specific information that specifies the detected terminal device, and uses the specific information to obtain a ratio equal to or higher than a predetermined probability. Is included in the number of terminal devices, and a value corresponding to this number is output as the number of persons.

According to such an abnormality notification system 1, when a terminal device outside the vehicle happens to be detected, it is possible to suppress erroneous detection of the number of persons based on the terminal device.
In the abnormality notification system 1 described above, the number-of-person detection ECU 10 acquires registration information that specifies one or a plurality of terminal devices registered in advance, and sets only the number of terminal devices included in the registration information as the number of terminal devices. Is output as the number of persons.

According to such an abnormality notification system 1, erroneous detection of the number of persons based on an unintended terminal device can be suppressed.
In the abnormality notification system 1 described above, the number-of-people detection ECU 10 also acquires, as registration information, information indicating characteristics of a person who has the terminal device.

According to such an abnormality notification system 1, since information indicating the characteristics of the person possessing the terminal device is also acquired, it is possible to detect the characteristics of the person having the vehicle.
In the abnormality notification system 1 described above, the number-of-people detection ECU 10 outputs registration information along with the number of persons.

According to such an abnormality notification system 1, since the registration information is output together with the number of persons, more detailed information about the occupant can be output.
In the abnormality notification system 1 described above, the emergency communication unit 35 acquires the number of persons in the vehicle, and acquires information indicating that there is an abnormality in the persons in the vehicle. Then, when it is determined that there is an abnormality, the emergency communication unit 35 notifies abnormality information including the number of persons to the outside of the vehicle.

According to such an abnormality notification system 1, when it is acquired that a person in the vehicle has an abnormality, it is possible to output including the number of persons.
In the abnormality notification system 1 described above, the emergency communication unit 35 acquires the number of persons output from the number-of-people detection ECU 10 described above.
