  The emergency notification system of this embodiment has such a configuration. Next, when the mobile terminal device 200 or the like is connected to the in-vehicle device 100, the type is specified, and then an emergency notification is made when an abnormality is detected. The operation will be described.

  FIG. 4 is a flowchart showing an operation procedure of the in-vehicle device 100 that identifies the type of the terminal device when it is connected. When a user who has a terminal device (any one of the mobile terminal devices 200 and 210 and the mobile phone 220) approaches the in-vehicle device 100 and enters the communicable area, the BT connection processing unit 111 displays the terminal device. A pairing process for the target is performed (step 100).

  Next, the service search unit 112 uses the SPP-UUID (Universally Unique Identifier) prepared in advance for the iPhone SPP to execute an SPP service search for the connected terminal device (step 102). It is determined whether this SPP service is supported (step 104). If it is supported, an affirmative determination is made, and the terminal device specifying unit 113 determines that the connected terminal device is the mobile terminal device 200 (iPhone) (step 106).

  If the iPhone SPP service is not supported, a negative determination is made in step 104. Next, the service search unit 112 uses the SPP-UUID prepared in advance for the SPP of the Android terminal to execute an SPP service search for the connected terminal device (step 108). It is determined whether or not it is supported (step 110). If it is supported, an affirmative determination is made, and the terminal device specifying unit 113 determines that the connected terminal device is the mobile terminal device 210 (android terminal) (step 112).

  If the Android terminal does not support the SPP service, a negative determination is made in the determination in step 110. Next, the service search unit 112 executes a service search corresponding to the DUN for the connected terminal device (step 114), and determines whether the service of this DUN is supported (step 116). If it is supported, an affirmative determination is made, and the terminal device specifying unit 113 determines that the connected terminal device is the mobile phone 220 (step 118).

  Thus, when any one of the mobile terminal devices 200 and 210 and the mobile phone 220 is connected to the in-vehicle device 100, the in-vehicle device 100 can specify the type of the connected terminal device. If the DUN service is not supported, a negative determination is made in step 116. In this case, the connected terminal device (or other Bluetooth device) does not support SPP or DUN services.

  FIG. 5 is a flowchart showing an operation procedure of the in-vehicle device 100 that detects an abnormality and issues an emergency call after specifying the type of the terminal device. Since this operation procedure is for making an emergency call, it is assumed that any one of the mobile terminal devices 200 and 210 and the mobile phone 220 is already connected to the in-vehicle device 100 via Bluetooth.

  The emergency call processing unit 114 determines whether or not the connected terminal device is iPhone (mobile terminal device 200) (step 200). If the iPhone is connected, an affirmative determination is made and the user is instructed to activate the emergency call application and put the emergency call processing unit 211 of the mobile terminal device 200 into an operable state ( Step 202). This instruction is performed, for example, by displaying a screen for instructing activation of the emergency call application on the display unit 153.

  The following description will be made on the assumption that the emergency notification application is activated by the user in response to this instruction, and that the emergency notification processing unit 211 of the mobile terminal device 200 shifts to an operable state. Further, when the emergency notification processing unit 114 of the in-vehicle device 100 can instruct the mobile terminal device 200 to start the emergency notification application, the operations of these steps 200 and 201 may be omitted.

  Next, or after the connected terminal device is not iPhone but a negative determination is made in step 200, the emergency call processing unit 114 determines whether it is the timing of the emergency call (step 204). When the abnormality detection unit 120 detects an abnormality to be an emergency call, or when the user gives an emergency call instruction using the operation unit 150 or the touch panel 151, the emergency call timing is set. In this case, a negative determination is made in the determination in step 204, and this timing determination is repeated.

  If the emergency call timing has arrived, an affirmative determination is made in step 204. Next, the emergency call processing unit 114 determines whether the connected terminal device is an iPhone (mobile terminal device 200) or an Android terminal (mobile terminal device 210) (step 206). If the connected terminal device is an iPhone or Android terminal, a positive determination is made. Next, the emergency call processing unit 114 performs connection using these SPPs to these terminal devices and transmits an emergency call instruction (step 208).

  By the way, the process of transmitting the emergency call instruction differs depending on whether the connected terminal is an iPhone or an Android terminal. Specifically, the outline of the process is as follows.

(For iPhone)
(A1) Connect using iPhone and SPP.
(A2) An authentication process between the in-vehicle device 100 and the mobile terminal device 200 is performed according to a protocol for communicating with an iPhone application (application program) defined by Apple.
(A3) Various information necessary for transmission of emergency information from the mobile terminal device 200 to the emergency call server 300 is transmitted and received between the in-vehicle device 100 and the mobile terminal device 200 according to the protocol.
(A4) The emergency call processing unit 211 of the mobile terminal device 200 makes an emergency call to the emergency call server 300 using various information received from the in-vehicle device 100.

(Android terminal)
(B1) Connect to Android terminal using SPP.
(B2) The emergency notification application of the Android terminal is activated in the background to make the emergency notification processing unit 211 operable.
(B3) According to the communication protocol between the in-vehicle device 100 and the mobile terminal device 210, various information necessary for transmitting emergency information from the mobile terminal device 210 to the emergency call server 300 is transmitted and received.
(B4) The emergency call processing unit 211 of the mobile terminal device 210 makes an emergency call to the emergency call server 300 using various information received from the in-vehicle device 100.

  On the other hand, if the connected terminal device is not an iPhone or Android terminal (in the case of the mobile phone 220), a negative determination is made in the determination of step 206. Next, the emergency call processing unit 114 performs a process of making an emergency call directly to the emergency call server 300 via the DUN-connected mobile phone 220 (step 210).

  Thus, in the emergency call system of this embodiment, the in-vehicle device 100 identifies the connection method (service) with the terminal device, and by identifying the type of the terminal device based on the identified connection method, Even when any of a plurality of types of terminal devices (the mobile phone 220 and the mobile terminal devices 200 and 210) is connected, an emergency call can be made to the emergency call server 300 via the connected terminal device. It becomes possible.

An emergency call can be made using the portable terminal devices 200 and 210.

  Further, in general, it is more effective to make an emergency call by using the mobile terminal devices 200 and 210 connected using the SPP than to make an emergency call via the mobile phone 220 connected using the DUN. Since the communication time with 300 can be shortened, the communication cost can be reduced by performing the emergency call by identifying the SPP first.

  In addition, the connection using SPP (first connection method) includes a third connection method in which a terminal device (iPhone) using iOS as the operating system is connected, and a terminal device using Android as the operating system. And a fourth connection method for connecting (Android terminal), and these are also identified. Thereby, it becomes possible to make an emergency call even if any of the iPhone and Android terminal having different processing contents regarding the emergency call is connected to the in-vehicle device.

  In addition, the mobile terminal devices 200 and 210 connected using the SPP are provided with an emergency call processing unit 210 (emergency call application), and the emergency call processing unit 114 of the in-vehicle device 100 receives the emergency call processing unit 210. To send emergency information. Thereby, when the mobile terminal devices 200 and 210 are connected using the SPP, it is possible to send an emergency notification to the emergency notification server 300 by sending an instruction to the mobile terminal devices 200 and 210. Become.

  For the mobile phone 220 connected using DUN, the emergency call processing unit 114 of the in-vehicle device 100 performs a process of transmitting emergency information. This makes it possible to make an emergency call directly from the in-vehicle device 100 to the emergency call server 300 via the mobile phone 220 connected using DUN.

  In this embodiment, the in-vehicle device 100 is connected to the mobile terminal devices 200 and 210 and the mobile phone 220 by communication using the Bluetooth method.
