[0051] (operation of the wireless communication module ^_ Le)

In the wireless communication module 10, the control unit 13 communicates with the communication partner 50 when a vehicle accident occurs while communicating with the communication partner 50 via the network 30. After being disconnected? 3? Make an emergency call to 40. Specifically, the wireless communication module 0 cannot establish communication with multiple communication partners at the same time, so after disconnecting communication with the communication partner 50

Communicate with eighty-four.

[0052] The control unit 13 notifies the communication partner 5 0 of the reason for disconnection before the communication with the communication partner 50 is disconnected in order to make an emergency call. The reasons for disconnection to notify the communication partner 50 are 1) that a vehicle accident has occurred, 2) make an emergency call to notify the occurrence of a vehicle accident, and 3) disconnect communication to make an emergency call. , Including at least one of.

[0053] With this, it is possible to prevent the communication partner 50 from immediately transmitting to the wireless communication module 10 after the communication is cut off, and it is possible to smoothly make an emergency call from the wireless communication module 1 0 to 3840. Becomes

When notifying the communication partner 50 of the reason for disconnection, the control unit 13 may notify the communication partner 5 0 that a call prohibition to the wireless communication module 10 is requested. For example, the control unit 13 informs the communication partner 50 such as "I will make an emergency call because an accident occurred. Please disconnect from here for a while." As a result, it is possible to more reliably prevent the communication partner 50 from immediately transmitting to the wireless communication module 10 after disconnection of communication.

As described above, there are two types of triggers for starting an emergency call, an automatic trigger and a manual trigger. In the case of the automatic trigger, the control unit 13 detects the occurrence of a vehicle accident and notifies the disconnection reason based on the detection of the occurrence of the vehicle accident. When an emergency call is started by an automatic trigger, it is highly possible that a serious accident has occurred.Therefore, the occupant notifies the communication partner 50 of the reason for disconnection by voice or text. It is considered difficult to do so. Therefore, the control unit 13 automatically notifies the disconnection reason based on the detection of the occurrence of the vehicle accident.

On the other hand, in the case of a manual trigger, the control unit 13 notifies the reason for disconnection based on the fact that the emergency call operation was performed by the occupant of the vehicle 20. When the occupant performs a predetermined operation after the emergency notification operation is performed by the occupant, the control unit 13 may omit the notification of the disconnection reason and disconnect the communication to make the emergency notification. The predetermined operation is, for example, pressing the emergency call button twice in a row or pressing the emergency call button for a long time. When an emergency call is started by a manual trigger, the occupant can notify the communication partner 50 of the reason for disconnection by voice or text, so the notification of the reason for disconnection can be omitted at the discretion of the occupant.

When the communication with the communication partner 50 at the time of occurrence of a vehicle accident is a voice call, the control unit 13 notifies the reason for disconnection by reproducing voice data indicating the reason for disconnection in this voice call. The audio played in this way is sometimes called the command prompt.

On the other hand, when the communication with the communication partner 50 at the time of the vehicle accident is data communication, the control unit 13 disconnects by transmitting a message including data indicating the disconnection reason to the communication partner 50. Notify the reason. The data indicating the disconnection reason may be text data. The message may be an email or SMS (ShortMeSsagEServic). Here, when the type of data communication is a predetermined type, the control unit 13 may omit communication of the reason for disconnection, disconnect communication, and make an emergency call. For example, when the type of data communication is Internet browsing, the control unit 13 omits the notification of the disconnection reason and disconnects the communication because there is no need to notify.

[0068] In Step 3 2 2, the wireless communication module 10 (control unit 13) receives an emergency call operation from the occupant.

In step 3 23, the wireless communication module 10 (control unit 13) determines whether or not an operation (predetermined operation) for omitting the notification of the reason for disconnection has been performed by the occupant. If the predetermined operation is not performed, the process proceeds to step 324. If the predetermined operation is performed, the process proceeds to step 326.

In step 3 24, the wireless communication module 10 (control unit 13) notifies the communication partner 5 0 of the reason for disconnection.

[0071] In step 325, the wireless communication module 10 (control unit 13) determines whether or not an operation of disconnecting communication from the occupant (for example, a call end operation) has been performed. \¥0 2020/175583 13 卩 (: 170? 2020 /007862

It If the operation of disconnecting the communication is performed, the process proceeds to step 3 2 6. However, the wireless communication module 10 (control unit 13) may automatically disconnect the communication with the communication partner 50 (Step 3 2 6) after notifying the disconnection reason (Step 3 2 4). ..

[01 17] (the operation of the wireless communication module ^_ Le)

In the wireless communication module 10, the control unit 13 makes an emergency call to 340 via the communication unit 12 when a vehicle accident occurs. When the predetermined condition indicating that the vehicle accident is a serious accident is satisfied, the control unit 13 sends an emergency call to 340 and asks. 3? Perform notification processing to notify an emergency contact other than 40 of a vehicle accident. If the predetermined condition is not satisfied, the control unit 13 does not perform the notification process to the emergency contact,

Make an emergency call to 940.

[01 18] The emergency contact is a preset contact, for example, a family member or a company. Emergency contact information (eg phone number, email address) is stored in the memory 1 \\0 2020/175583 21 21 (: 170? 2020/007862

Pre-stored in 4.

[01 19] The notification process for notifying an emergency contact of a vehicle accident includes the first mode of sending the information of the emergency contact to 340 and the second mode of sending the information of the vehicle accident to the emergency contact. There are modes. In other words, there is a notification process two ways mode as a mode _ soil to the emergency contact, the control unit 1 to 3, thus performs the notification process to either ^_ square mode.

[0120] In the first mode, the vehicle accident is notified to the emergency contact directly through the wireless communication modules 10 to 380. In the second mode, the vehicle accident is notified directly to the emergency contact without going through the wireless communication modules 10 to 340. The details of the first mode and the second mode will be described later.

[0121] The predetermined condition indicating that the vehicle accident is a serious accident may be that an emergency call to 340 was automatically made. When the emergency call to 380 40 is automatically made, the control unit 13 asks,? 3? Performs emergency call to 40 and notification processing to emergency contact.

If an emergency call to 40 is made automatically, there is a high possibility of a serious accident, and it is considered highly necessary to notify the emergency contact. Therefore, the control unit 13 is supposed to perform notification processing to emergency contacts.

[0122] However, when an emergency call to 3840 is manually made, the control unit 13 does not perform the notification process to the emergency contact, and the? 3? Make an emergency call to 40. If an emergency call to 840 is made manually, it is considered that at least the occupants are conscious, the possibility of serious accident is low, and the necessity to notify emergency contact is low. .. Therefore, the control unit 13 does not process the notification to the emergency contact.

[0123] However, whether or not the notification process to the emergency contact is performed when the emergency call to 340 is made manually may be switchable by the user setting.

[0124] The predetermined condition that indicates that the vehicle accident is a serious accident is the airbag of the vehicle 20.

It may be that 24 is activated. The control unit 13 is designed to \¥0 2020/175583 22 卩 (: 170? 2020 /007862

When Abbag 24 is activated, emergency call is sent to 340 and notification is sent to the emergency contact. If the airbag 24 is activated when a vehicle accident occurs, it is highly likely that a serious accident has occurred and it is highly necessary to notify the emergency contact. Therefore, the control unit 13 is supposed to perform notification processing to the emergency contact.

[0125] On the other hand, if the airbag 24 is not in operation at the time of the vehicle accident, the control unit

1 3 without having to process the notification to the emergency contact? Make an emergency call to 340. If the airbag 24 is not in operation at the time of a vehicle accident, it is unlikely that a serious accident has occurred and the need to notify the emergency contact is low. Therefore, the control unit 13 does not perform the notification process to the emergency contact.

[0126] However, whether or not to perform notification processing to the emergency contact destination when the airbag 24 is not in operation when a vehicle accident occurs may be switchable by user setting.

[0127] As described above, when the predetermined condition indicating that the vehicle accident is a serious accident is not satisfied, the control unit 13 does not perform the notification process to the emergency contact information and notifies the emergency of 3840. Make a call. As a result, in the case of a minor vehicle accident and/or a vehicle accident report triggered by a manual trigger, it is possible to prevent the emergency contact from being notified. On the other hand, if the vehicle accident is a serious accident, the control unit 13 can promptly notify an emergency contact such as a family member that the vehicle accident occurred.

[0128] FIG. 9 is a diagram showing an emergency call operation when the notification processing in the first mode is performed.

As shown in FIG. 9, in step 3 31 the control unit 13 of the wireless communication module 10 detects the occurrence of a vehicle accident based on the information from the vehicle control unit 21. For example, the information from the vehicle control unit 21 includes information indicating that an emergency call is to be started, and the type of trigger for starting an emergency call (automatic or manual). When the vehicle control unit 21 notifies that the emergency call is started, the control unit 13 detects the occurrence of the vehicle accident. Alternatively, the information from the vehicle control unit 2 1 includes the sensor 2 3 \¥0 2020/175583 23 卩 (: 170? 2020 /007862

The detection result of 1 may be included. The control unit 13 may detect the occurrence of a vehicle accident when the sensor 23 detects an impact exceeding a predetermined value.

In step 3 32, the control unit 13 of the wireless communication module 10 makes an emergency call to 340 via the communication unit 12. Specifically, the control unit 13 makes an emergency call using a preset emergency call telephone number.

[0131] In Step 3 3 3, the communication unit 12 of the wireless communication module 10

The call response is received from 840. As a result, a call is established between the wireless communication modules 10 and 380.

[0132] In step 334, the controller 13 of the wireless communication module 10 communicates.

Similar to the first embodiment, it has the format shown in FIG. As shown in Figure 2,

It has an optional area that can store arbitrary information. The control unit 13 includes information about the emergency contact 60 (for example, telephone number, e-mail address) in this optional area. By using the option area,

The information of the emergency contact 60 can be made known to 3840 without changing the message format of.

[0133] In Step 335, the communication unit 12 of the wireless communication module 10

Is an acknowledgment that the IV! 30 was received correctly.

[0134] In step 336, 3840 is an emergency contact included in IV!30.

Using the information from 60, notify the emergency contact 60 of the accident.

[0135] In the first mode, it is necessary to previously register the information of the emergency contact destination 60 in the storage unit 14 of the wireless communication module 10 as the information to be included in the option area of 1\/130. Such registration may be performed by the dealer of the vehicle 20 or may be performed by the user.

[0136] However, since the information on the emergency contact 60 is privacy information, it is assumed that some users do not want the information on the emergency contact 60 to be known to 380. Also, due to the data capacity of the option area of IV! \¥0 2020/175583 24 24 (: 170? 2020 /007862

It is also envisioned that the emergency contact 60 information may not be included in the IV! 30 optional area. In such a case, the information of the emergency contact 60 is not registered in the storage unit 14 of the wireless communication module 10 as the information to be included in the option area of IV!

[0137] Therefore, if the information of the emergency contact 60 is not registered in the storage unit 14 of the wireless communication module 10 as the information to be included in the option area of IV! I will do it.

[0138] FIG. 10 is a diagram showing an emergency call operation in the case of performing the notification process in the second mode.

[0139] As shown in Fig. 10, the operations of steps 341 to 343 are performed in the same manner as the notification processing of the first mode.

[0140] In step 344, the control unit 13 of the wireless communication module 10 uses the communication unit 12 to make an emergency contact.

Send.

[0141] In Step 3 45, the communication unit 12 of the wireless communication module 10

[0142] In step 346, the control unit 13 of the wireless communication module 10 sets IV!

0 80 1 <? In response to the reception from 380 40, a message including information about the vehicle accident is transmitted to the emergency contact 60 via the communication unit 12. For example, the message

3 6 “10 6). The message may be an email.

[0143] In the second mode, the emergency contact information is used as the destination information to send the message.

It is necessary to register the information of 0 in the storage unit 14 of the wireless communication module 10 in advance. Such registration may be performed by the dealer of the vehicle 20 or may be performed by the user.

FIG. 11 is a diagram showing a mode selection operation of the notification process in the wireless communication module 10.

[0145] In step 3201, the wireless communication module 1 \\0 2020/175583 25 卩 (: 170? 2020 /007862

The control unit 13 of ◯ determines whether or not a vehicle accident has occurred.

[0146] When it is determined that a vehicle accident has occurred (Step 3201: Tomi 3), in Step 3202, the controller 13 of the wireless communication module 10 selects the communication unit 1 2. Make an emergency call to 340 via.

[0147] In step 3203, the controller 13 of the wireless communication module 10 determines whether or not a predetermined condition indicating that the vehicle accident is a serious accident is satisfied. When the predetermined condition is not satisfied (step 3203: N0), the control unit 13 performs a normal emergency call operation without notification processing to the emergency contact.

[0148] On the other hand, when the predetermined condition indicating that the vehicle accident is a serious accident is satisfied (step 3203: No.3), in step 3204, the wireless communication module 10 The control unit 13 determines whether or not the emergency contact information to be included in IV! 30 is registered.

[0149] If emergency contact information is included for inclusion in 1\/1300 (step

324: In step 3205, the controller 13 of the wireless communication module 10 selects the first mode notification process in step 320.

[0150] — If the emergency contact information for inclusion in 1\/1 30 is not registered (step 3204:N0), then in step 3206 the wireless communication module 1 The control unit 13 of 0 selects the notification process of the second mode.

[0151] Then, the control unit 13 performs the notification process to the emergency contact according to the selected mode from the first mode and the second mode.

[0152] [Modification Example of Second Embodiment]

The predetermined condition indicating that the vehicle accident is a serious accident may be based on the vehicle speed, the acceleration, the collision speed, and/or the presence/absence of seat belt wearing by the occupant when the vehicle accident occurs. For example, the control unit 13 of the wireless communication module 10 may determine that the vehicle accident is a serious accident when the vehicle speed, the acceleration, or the collision speed at the time of the vehicle accident exceeds a threshold value. When the vehicle speed, acceleration, or collision speed at the time of a vehicle accident exceeds the threshold value and the occupant is not wearing the seat belt, the vehicle accident causes a serious accident. And \¥0 2020/175583 26 卩 (: 170? 2020 /007862

May be determined.

[0153] After the control unit 13 of the wireless communication module 10 selects the first mode and starts the notification process to the emergency contact,

It is assumed that the 801< could not be received within a certain period of time. In such a case, the control unit 13 of the wireless communication module 10 may consider that some abnormality has occurred in 380 and may switch to the second mode and perform notification processing to the emergency contact. ..

And the like. The wireless communication module 10 may be configured as a semiconductor integrated circuit (chip set, 300) by integrating functional units (circuits) that execute each processing performed by the wireless communication module 10.
