Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a vehicle mounted on a vehicle,
The present invention relates to a vehicle accident response device that performs a predetermined accident response operation when an accident occurs.

[0002]

2. Description of the Related Art Conventionally, various devices such as an anti-lock brake system have been developed to ensure the running safety of a vehicle so as to ensure safer running. However, even if the running performance of the vehicle increases, it is not always possible to eliminate the occurrence of an accident. Therefore, in order to improve the safety of the occupant in the event of an accident, devices such as seat belts and airbags are also used.

[0003] Further, in an accident involving an injury of an occupant or the like, prompt emergency notification is desired. Therefore, Japanese Patent Laid-Open No.
No. 7198 describes that an emergency call is automatically made when an accident occurs by using a car phone. That is, in the device described in this publication, when an accident is detected by the operation of an airbag, an acceleration sensor, or the like, a car phone is automatically transmitted to an emergency contact point such as a hospital or police registered in advance. Make an emergency call specifying the location of the vehicle.

[0004] With such an emergency call system, an emergency call can be made even when an occupant is injured and cannot operate such as a telephone.

[0005]

Here, when the condition of the accident is relatively light and the occupant is conscious, the occupant has the ability to take appropriate action to some extent. In such a case, there is something to do other than the above-mentioned emergency call. However, at the time of the accident,
Due to the occurrence of the accident, the person is unable to stay calm and often cannot take appropriate measures. Therefore, even if the occupant has the ability to perform the treatment action, there has been a problem that sufficient measures are often not taken. In addition,
In the above-described conventional example, an emergency call, which is one action to be taken when an accident occurs, is automatically performed, but other necessary measures are not improved at all.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to provide a vehicular accident response device capable of providing appropriate assistance in the event of an accident.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a vehicular accident response device mounted on a vehicle and performing a coping operation in the event of an accident, comprising: a message output means for outputting a message; Detecting means, and accumulating means for accumulating a human accident handling coping model at the time of occurrence of the accident, and outputting a message based on the behavior model accumulated in the accumulating means when the occurrence of the accident is detected. Output from the means.

As described above, when an accident occurs, a message about necessary measures is output. Therefore,
The crew can follow the message and take necessary measures. For example, since the device issues an emergency call or an instruction to turn off the engine, such a measure is reliably performed. Further, by displaying the current location necessary for other emergency calls, it is possible to reliably transmit necessary information when the occupant calls.

Further, the present invention further comprises a state confirmation means for confirming a state of an occupant at the time of occurrence of an accident based on a response to a voice inquiry, and communicating with an external organization,
Communication means for making an emergency call, and if the state of the occupant is normal as a result of this state confirmation, a message is output by the message output means based on the behavior model, and if the state of the occupant is not normal, Is characterized by making an emergency call to an external organization by the communication means.

As described above, when the occupant is normal, the occupant assists the behavior of the occupant and ensures that the occupant takes necessary measures.
Thereby, necessary measures after an accident can be maximized. On the other hand, when the occupant is not normal, a high-priority emergency call is automatically made. As a result, the minimum accident handling can be reliably performed.

Further, the present invention is characterized in that the message output means is used as guidance output means for outputting guidance information in a navigation device when no accident occurs. In this way, by sharing the output means with the navigation device, the device can be used effectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention (hereinafter referred to as embodiments) will be described below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of the device according to the present embodiment. A navigation device 10 has a navigation ECU 12 and a display 14 connected thereto. In addition, it also has a not-illustrated GPS device for position evaluation, a map database for storing map data, and the like. Then, the navigation ECU 12 performs a process for normal route guidance using data from these devices. That is, when a destination is set, an optimal route from the current location to the destination is searched using the map data. In addition, during traveling, the current position is always recognized, and the detected current position is displayed on the display 14 together with a map of the surroundings.
In addition, during traveling with a route set, at a guidance intersection where a right or left turn or the like is performed, an enlarged display of the intersection is displayed on the display 14 to indicate the traveling direction. Therefore, the driver can easily travel along the route with reference to the display on the display 14.

Further, a speaker 16 is connected to the navigation device 10 as audio output means. The navigation ECU 12 is provided at a guidance intersection or the like.
The speaker 16 is driven to output a voice guidance message. For example, just before the guidance intersection,
A voice message such as “The intersection ahead is to the left at the intersection.” Is output from the speaker 16.

In the present embodiment, the navigation ECU 12 also controls various operations when an accident occurs. For this reason, the navigation ECU 1
2, an airbag sensor 18 is connected. The airbag sensor 18 detects an operating state of the airbag, and thereby detects occurrence of an accident. That is, the airbag is activated when a vehicle collision or the like is detected by an acceleration sensor or the like. Therefore, the occurrence of an accident can be detected by operating the airbag. Note that, instead of the airbag sensor 18, an accident may be detected by an acceleration sensor, an impact sensor installed on a bumper or the like.

The navigation ECU 12 is connected to a microphone 20, an emergency button 22, and a car phone 24. The microphone 20 detects an occupant's voice and the like, and the emergency button 22 detects an occupant's operation on this button. The car phone 24 is normally used as a normal car phone, but in an emergency, uses its automatic calling function to make a call with an emergency contact.

Further, the navigation ECU 12 includes:
The behavior model accumulation database 26 is connected. The behavior model accumulation database 26 stores the behavior pattern to be taken by the occupant when an accident occurs.

When detecting the occurrence of an accident based on a signal from the airbag sensor 18, the navigation ECU 12 contacts the occupant using the speaker 16, the display 14, the microphone 20, and the emergency button 22, and responds to the result. To determine the state of the occupant. And
If it is determined that the occupant can take a normal action (normal), based on the data in the action model accumulation database 26, the transmission of the car phone 24 and the output of the action guidance by the display 14 and the speaker 16 are performed.

The overall operation in the event of an accident will now be described with reference to FIG. First, it is determined whether an accident has occurred based on the detection result of the airbag sensor 18 (S1).
1). This determination is always made. When the occurrence of an accident is detected, the navigation ECU 12
The speaker 16 outputs a question such as "Is it okay. If you can act, please operate the emergency button or answer high" (S12). Then, it is determined whether there is a response to this (S1).
3). This determination is made based on whether the emergency button 22 has been operated or a response has been received from the microphone 20. Recognition of whether or not there is a response of "high" is performed by voice recognition. Although the emergency button 22 may be used for the response of the occupant, it is preferable to install a touch panel on the front of the display 14 and detect a touch on the display 14 to detect the response. On this occasion,
A touch may be requested for the display of contacting the emergency contact, and a response may be recognized by a corresponding touch. S
The output of the 12 questions may be repeated several times when there is no response. If there is a response, it is determined that the occupant can act by himself (normal), the data is read from the behavior model accumulation database 26, and the occupant's behavior is assisted (S14). On the other hand, if there is no response, an automatic call (emergency call) is made to a predetermined emergency contact using the car telephone 24 (S15).

Next, the assistance of the occupant in S14 will be described with reference to FIG. First, an inquiry is made from the display 14 and the speaker 16 as to whether or not to make an emergency contact (S21). This inquiry is sent to display 1
4 and audio output from the speaker 16. If the response from the occupant is YES, an automatic call is made to a predetermined emergency contact (S22). The crew response is
For example, the detection is performed by detecting a touch on a touch panel provided on the front surface of the display 14. Here, the automatic destination (emergency contact) differs depending on the current location. Therefore, the corresponding emergency contact information is read from the map database from the current location known by the navigation device 10, and the emergency contact information is determined.

Then, it is determined whether the line has been established (S2).
3) If the line is not connected, automatic transmission is performed again. Although illustration is omitted, if the line is not established by a predetermined number of automatic calls, a process such as changing the automatic call destination to the next emergency contact may be performed.

In S23, when the line is connected,
A predetermined data display is performed (S24). This data display is performed according to the data on the behavior pattern stored in the behavior model storage database 26.

For example, a message indicating that the emergency contact is currently being made, the current location, the current time, the time when the accident occurred, etc., as well as "Turn off the engine." Please do. " Further, personal data is displayed as an aid to the call. That is, the user's name, gender, date of birth, address, blood type,
The necessary information such as the type and number of the car is displayed. Thus, necessary information can be conveyed to the other party in a call with the emergency contact. In particular, immediately after the accident, there are many cases in which the user is upset, and the presence of such a display enables accurate information transmission.

Next, it is determined whether the call has been completed (S2).
5) Until the end, the above display is performed. On the other hand, when the call is terminated, a message such as "Do you want to contact other emergency contacts?" Or "Do you want to display the first aid menu?" Is displayed. Depending on,
Further, various data are displayed (S26).

When the display of other emergency contacts is requested, the telephone numbers of other police, insurance companies, homes, offices, etc. are displayed together with the displayed emergency contacts. If the display of the first aid menu is selected, the location of the first aid kit such as "The first aid kit is in the trunk." A simple treatment guide will be given accordingly. this is,
This is effective when the passenger as well as the passenger is injured. The treatment guide may operate a conventionally known emergency treatment diagnostic program or the like. Further, it is also preferable to display a hospital near the current location. In this way, information that the occupant wants to know is easily displayed on the display 14. Further, the output may be a sound output from the speaker 16.

Therefore, the occupant can take appropriate action according to the display on the display 14 and the guide voice from the speaker 16.

Then, a display as to whether or not to end is also displayed on the display 14, and when this is touched, the processing at the time of occurrence of the accident is ended. It is preferable that data such as the location of the accident, the time of the occurrence of the accident, the destination of the emergency contact, and the like be stored and output at any time.

If the car telephone 24 is not available or cannot be used, the map database is searched, and the nearest telephone or a facility to which a call can be made is displayed and voice guidance is provided. For example, guidance such as “There is an emergency call at the XX km post that has progressed about XXm toward XX”.

FIG. 4 shows a flowchart of the processing by the automatic call in S15. First, the current location is acquired (S31). This is performed by the navigation ECU 12 based on the current location data. Then, it is determined whether or not the vehicle is on an expressway using the map data from the current location (S3).
2).

In this S32, in the case of YES,
As a contact, a road corporation, which is a manager of the expressway, is selected as a contact (S33). This road public corporation is preferably a center having jurisdiction over the place, and is preferably stored in a map database in advance. Next, the current position on the expressway, that is, position data of “near the XX interchange destination XX post” is acquired (S34). Then, the telephone number of the road corporation stored in the map database is read, and a call is made by automatic transmission. Then, when the line is established, the occurrence of the accident is automatically reported (S35). This report includes information on the current location (accident location) obtained as described above.

On the other hand, if it is determined in step S32 that the vehicle is not on an expressway, a police station is selected (S36), and the name of the road, whether the vehicle is going up or down, and the like are acquired (S37). And
A call is made to the police to report the occurrence of the accident including the current location (S38).

Here, the report of the occurrence of the accident may be output by voice, but may be transmitted by character data or map data by facsimile, or by data communication if the other party accepts the report. Also, at the time of displaying the data in S24 of FIG. 3, it is preferable to obtain the emergency contact information and the position data by the same processing as in this flowchart.

As described above, according to the present embodiment, when the occurrence of an accident is detected, a question is first asked to the occupant by voice. Such audio questions also play a role in clarifying the occupants' awareness. When a response from the occupant is received, an inquiry is made as to whether or not to make an emergency call according to the data in the behavior model accumulation database 26. So don't forget the emergency call. In addition, since an emergency contact according to the current location is selected, a correct contact can be selected. Further, necessary measures such as turning off the engine are instructed. Therefore, the necessary measures are not forgotten. Also,
Since necessary data is displayed, an accurate accident report can be made when a call is made. On the other hand, if there is no response from the occupant, an accident report is made by automatic transmission. For this reason, even if the occupant cannot communicate, it is possible to report the occurrence of the accident.

In the present embodiment, the behavior model accumulation database 26 is also mounted on the vehicle, but it goes without saying that the behavior model accumulation database 26 can be downloaded from the outside if necessary. In this case, the behavior model accumulation database may be downloaded on an online line via a car telephone at the same time as the occurrence of the accident.
