Description

[Technical Field]

[0001] The present invention relates to a vehicle having an emergency call function and an emergency call system for a vehicle. [Background technology]

[0002] When a vehicle such as an automobile collides with another automobile while traveling, or an occupant becomes ill, the automobile will make an emergency call to an operator at an emergency assistance center (Patent Documents 1 and 2). When an emergency call is received, an operator at the emergency support center requests a dispatch unit to respond. The dispatch unit uses emergency vehicles to rush to the scene of the vehicle that made the emergency call and carry out the emergency response. This allows vehicles and occupants in the event of an emergency to receive emergency response. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-219488 [Patent Document 2] International Publication No. 2016 / 170610 Summary of the Invention [Problem to be solved by the invention]

[0004] Emergency response requires that appropriate responses and measures be taken according to the nature of the emergency. If emergency personnel discover a shortage of equipment after arriving at the scene, it will be difficult for them to immediately begin emergency response. Therefore, in order to respond to emergencies more appropriately, it is desirable for the operator at the emergency support center to speak to the occupants of the vehicle that made the emergency call to confirm the nature and extent of the emergency before requesting a response team to be dispatched. However, even if such a call confirmation can confirm the details of the emergency, it is not realistic to confirm more detailed information when an emergency response is required. For example, it is not realistic to confirm the medical history of the occupants of a vehicle in which an emergency has occurred during an emergency call. Furthermore, if the occupants are unconscious, it is not possible to confirm the call.

[0005] As such, there is a need for improvement in automated emergency notification systems. [Means for solving the problem]

[0006] A vehicle having an emergency call function according to one aspect of the present invention is a vehicle capable of transmitting an emergency call when an emergency occurs in the vehicle, and includes a vehicle communication unit that transmits the emergency call to an operator terminal that can access a memory in which emergency-related information including access restriction information about the vehicle or occupants is recorded and acquire the emergency-related information, and a vehicle memory that records authentication information for accessing the access restriction information recorded in the memory, wherein the vehicle communication unit: When an emergency situation occurs in the vehicle due to an accident, if the impact of the accident on the vehicle is equal to or greater than a threshold value and no response is obtained from the occupants of the vehicle after the accident, the authentication information recorded in the vehicle memory is automatically transmitted to the operator terminal together with an emergency call, The operator terminal uses the authentication information received from the vehicle to acquire the access restriction information from the memory as part of the emergency-related information. Even if the impact on the vehicle due to the accident is equal to or greater than a threshold, if a response from the vehicle occupant is obtained after the accident, only an emergency call is automatically sent to the operator terminal, and if the impact on the vehicle due to the accident is less than the threshold, an emergency call is not automatically sent. A vehicle having an emergency call function according to one aspect of the present invention includes: A vehicle capable of sending an emergency call when an emergency occurs in the vehicle, the vehicle having a vehicle communication unit that transmits the emergency call to an operator terminal that can access a memory in which emergency-related information including access restriction information about the vehicle or occupants is recorded and acquire the emergency-related information, and a vehicle memory that records authentication information for accessing the access restriction information recorded in the memory, wherein the vehicle communication unit acquires the authentication information recorded in the vehicle memory and sends the emergency call to the operator terminal only when an emergency occurs in the vehicle due to an accident of a predetermined level or above, or when no response is obtained from the occupants of the vehicle, and causes the operator terminal to acquire the access restriction information from the memory as part of the emergency-related information using the authentication information received from the vehicle, and sends the emergency call to the operator terminal without acquiring the authentication information recorded in the vehicle memory in other cases, including when the emergency call is made manually based on the operation of the occupants of the vehicle.

[0007] Preferably, the memory stores the vehicle driver's or passenger's medical history, underlying illnesses, chronic illnesses, medical history, medication and other health information, personal information, family information, or emergency contact information as the access restriction information.

[0011] Preferably, the vehicle memory records multiple pieces of authentication information for each occupant of the vehicle or for each group of occupants of the vehicle, and the vehicle communication unit selects at least a portion of the multiple pieces of authentication information recorded in the vehicle memory and transmits them to the operator terminal depending on the situation of the vehicle when an emergency occurs.

[0012] According to another aspect of the present invention, there is provided an emergency call system for a vehicle used when an emergency occurs in the vehicle, the emergency call system including: a server device having a server memory in which emergency-related information including access restriction information for the vehicle or an occupant is recorded; an operator terminal that accesses the server device to acquire the emergency-related information recorded in the server memory; and a vehicle having a vehicle communication unit that transmits an emergency call to the operator terminal, wherein the vehicle includes a vehicle memory that records authentication information for accessing the access restriction information recorded in the server memory. a vehicle communication unit that transmits an emergency call to an operator terminal that can access the server memory and obtain emergency-related information; and When an emergency situation occurs in the vehicle due to an accident, if the impact of the accident on the vehicle is equal to or greater than a threshold and no response is obtained from the occupants of the vehicle after the accident, the vehicle communication unit automatically transmits the authentication information recorded in the vehicle memory together with an emergency call from the vehicle communication unit to the operator terminal, if the impact of the accident on the vehicle is equal to or greater than a threshold but no response is obtained from the occupants of the vehicle after the accident, automatically transmits only the emergency call to the operator terminal, and if the impact of the accident on the vehicle is less than the threshold, does not automatically transmit the emergency call, When the operator terminal receives the emergency call from the vehicle, it uses the authentication information received from the vehicle to obtain the access restriction information from the server memory of the server device as part of the emergency-related information. A vehicle emergency call system according to another aspect of the present invention is a vehicle emergency call system used when an emergency occurs in the vehicle, and includes: a server device having a server memory in which emergency-related information including access restriction information about the vehicle or an occupant is recorded; an operator terminal that accesses the server device to acquire the emergency-related information recorded in the server memory; and a vehicle having a vehicle communication unit that transmits an emergency call to the operator terminal, wherein the vehicle includes a vehicle memory that records authentication information for accessing the access restriction information recorded in the server memory, and a vehicle communication unit that transmits an emergency call to the operator terminal that can access the server memory to acquire the emergency-related information. The vehicle communication unit acquires the authentication information recorded in the vehicle memory and transmits it from the vehicle communication unit to the operator terminal only when an emergency situation occurs in the vehicle due to an accident of a predetermined level or above, or when no response is obtained from the vehicle occupants, and in other cases, including when an emergency call is made manually based on the operation of the vehicle occupants, the vehicle communication unit transmits an emergency call to the operator terminal without acquiring the authentication information recorded in the vehicle memory, and when the operator terminal receives the emergency call from the vehicle, it acquires the access restriction information from the server memory of the server device as part of the emergency-related information using the authentication information received from the vehicle. [Effects of the Invention]

[0013] In the present invention, in the event of an emergency, the vehicle transmits authentication information stored in the vehicle's vehicle memory along with an emergency call to an operator terminal. When the operator terminal receives the emergency call from the vehicle, it can obtain access restriction information from the memory as part of the emergency-related information using the authentication information stored in the vehicle. In the present invention, there is no need to transmit emergency-related information, which tends to be large in volume, from the vehicle in which the emergency has occurred to the operator terminal. As a result, in the present invention, a vehicle in which an emergency has occurred can essentially transmit to an operator terminal, through light-load communication processing with a short lead time, information about the emergency and information related to the emergency. The operator terminal can reliably acquire information about the vehicle in which the emergency has occurred, regardless of the vehicle's status after the emergency has occurred, and use the information in subsequent emergency response processing. For example, even if a situation arises in which the vehicle cannot immediately acquire and transmit information from a location other than the vehicle memory due to a vehicle accident, the operator terminal can reliably acquire information usable for emergency response. In this way, the present invention makes it possible to reliably acquire information usable for emergency response at the operator terminal while reducing the communication load on the vehicle when transmitting an emergency call. In addition, in the present invention, access restriction information about a vehicle or occupants is recorded in a memory accessible by the operator terminal as part of the emergency-related information. The memory can also store information, such as the medical history, underlying illnesses, chronic illnesses, medications, and other health information of the vehicle driver or passengers, personal information, family information, or emergency contact information, while managing access restrictions. The operator can then operate the operator terminal to obtain the access restriction information as part of the emergency-related information about the vehicle or occupants related to the vehicle in which an emergency has occurred. Furthermore, in the present invention, authentication information for accessing the access restriction information is recorded in the vehicle memory of the vehicle and is transmitted to the operator terminal and made available only when an emergency occurs in the vehicle. In the present invention, by using the vehicle as a key device and restricting transmission of the authentication information only when an emergency occurs in the vehicle, part of the emergency-related information recorded in the memory accessible by the operator terminal can be securely stored in a state that is, for example, almost impossible to obtain under normal circumstances. This achieves confidentiality of information, secure storage, and prevention of unauthorized use. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] [First embodiment] FIG. 1 is an explanatory diagram of an automatic emergency call system 1 for a vehicle according to a first embodiment of the present invention. The automatic emergency notification system 1 in FIG. 1 includes an automobile 2 compatible with the system, an operator terminal 3 at an emergency support center, and a server device 4. The automobile 2 is an example of a vehicle that can carry passengers. A control system 30 of the automobile 2 establishes a communication path with a base station 6 whose zone includes the road on which the automobile 2 is traveling, using a mobile communication device 33 described below. The multiple base stations 6 are connected to a communication network 7. The base station 6 and the communication network 7 may be 5G provided by a carrier, or may be dedicated to, for example, an Advanced Driver Assistance System (ADAS) provided by a public institution or the like. The operator terminal 3 is connected to the communication network 7 and the local area network 5 of the emergency support center by a communication device 17, which will be described later. A server device 4 is connected to the local area network 5.

[0017] While traveling, the automobile 2 may collide with another automobile 9, or the driver or other occupant may become ill. When an emergency occurs in the automobile 2, the control system 30 of the automobile 2 executes an emergency call from a mobile communication device 33 (described later) to the operator terminal 3 of the emergency support center via the base station 6 and the communication network 7. An operator at the emergency support center checks the emergency call received by the operator terminal 3 and issues a request to the dispatch unit. The dispatch unit rushes in an emergency vehicle 8 to the scene where the automobile 2 that made the emergency call is located and carries out an emergency response. This allows the vehicle 2 and its occupants in the event of an emergency to receive emergency response from a dispatch unit.

[0018] In an emergency response, it is necessary to respond and take measures according to the nature of the emergency. For example, if there is a shortage of equipment after arriving at the scene, emergency response personnel will have to wait for the equipment to be arranged, and will not be able to immediately begin emergency response after arriving at the scene. Therefore, in order to respond to the emergency more appropriately, it is desirable for the operator of the emergency support center to speak with the occupants of vehicle 2 that made the emergency call before requesting a dispatch unit to respond, in order to understand the nature and extent of the emergency in advance. However, even if the operator can confirm the details of the emergency through a call, it is not realistic to confirm the details in a situation where an emergency response is required. For example, it is not always possible for the operator to check the medical history of the occupants of the vehicle 2 where the emergency occurred every time an emergency call is made. Furthermore, even if the operator makes a call, occupants who are unconscious due to an accident or the like cannot respond. Thus, the automatic emergency notification system 1 needs to be improved to enable more appropriate emergency responses.

[0019] FIG. 2 is an explanatory diagram of a computer device 10 that can be used as the server device 4 or the operator terminal 3 of FIG. 2 includes a CPU 11, a memory 12, a GNSS receiver 13, a timer 14, a display device 15, an operation device 16, and a communication device 17. Note that the computer 10 serving as the server device 4 may also include the CPU 11, the memory 12, the GNSS receiver 13, the timer 14, and the communication device 17. The computer 10 serving as the operator terminal 3 may include a microphone and a speaker (not shown) for communication.

[0020] The communication device 17 is connected to the communication network 7 and the local area network 5. When the communication network 7 is connected to the local area network 5 via, for example, a router device, only the local area network 5 may be directly connected to the communication device 17. The communication device 17 sends and receives communication data to and from the computer device 10.

[0021] The display device 15 is, for example, a liquid crystal monitor, and displays a screen to the operator. The display screen of the display device 15 may be, for example, an emergency call screen, a call screen, a dispatch request screen, and the like. The emergency call screen is a screen that displays whether or not an emergency call has been made, the contents of the emergency call, etc. The contents of the emergency call may display the location of the vehicle 2 that made the emergency call, the time of the call, the reported or predicted status of the vehicle 2 and its occupants, etc. It may also display whether or not there are other emergency calls occurring nearby. The call screen may be, for example, a call screen to the mobile terminal of the automobile 2 or the occupant of the automobile 2 that has received the emergency call. The dispatch request screen may be a screen requesting a dispatch unit near the site of the emergency.

[0022] The operation device 16 is, for example, a keyboard, a pointing device, a touch panel, a button, etc., and is operated by an operator. The operator operates the operation device 16 to switch the display screen of the display device 15, for example.

[0023] The GNSS receiver 13 receives radio waves from the GNSS satellites 101 shown in Fig. 1 and generates the current time. The GNSS receiver 13 may obtain the installation position of the computer device 10 along with the current time.

[0024] The timer 14 measures time or the time of day. The time of the timer 14 may be calibrated by the current time of the GNSS receiver 13.

[0025] The memory 12 stores programs and data for causing the computer device 10 to function as the server device 4 or the operator terminal 3 .

[0026] The CPU 11 reads and executes a program from the memory 12. As a result, the CPU 11 functions as a control unit that controls the overall operation of the server device 4 or the operator terminal 3. When the operator terminal 3 accesses the communication device 17, the CPU 11 as the control unit of the server device 4 transmits data from the communication device 17. The CPU 11 as a control unit of the operator terminal 3 receives an emergency call from the automobile 2, switches the display on the display device 15 in response to an operation by the operator, and executes control based on the operation on the display screen. Examples of control based on the operation on the display screen include control of calling the automobile 2 or the occupant that made the emergency call, control of accessing the server device 4 to obtain information recorded in the memory 12 of the server device 4, and control of calling the emergency call.

[0027] FIG. 3 is an explanatory diagram of the memory area 20 in the memory 12 of the server device 4 of FIG. 3, an owner database 22 is recorded in an area where access from the operator terminal 3 is not restricted, and a plurality of access-restricted files where access from the operator terminal 3 is restricted are recorded. The files in the access-restricted area 21 include, for example, owner files (Owner1, Owner2) 23, 24 for each vehicle 2, and a group file (Group1) 25 for each occupant group of the vehicle 2. The files recorded in the access-restricted area 21 may be recorded in an encoded state in which the data can be expanded using a password.

[0028] FIG. 4 is an explanatory diagram of the owner database 22 recorded in the memory area 20 of FIG. In the owner database 22 of FIG. 4, information about a plurality of vehicles 9 for which emergency situations are managed by the emergency assistance center is recorded as a plurality of records for each vehicle 2.

[0029] The record for each vehicle 2 includes at least, for example, vehicle identification information for uniquely identifying each vehicle 2, minimum basic information about the vehicle 2 and its owner, and link information included in the basic information to files in the access restricted area 21 for the vehicle 2 and its owner. The vehicle identification information may be information unique to each automobile 2. For example, the vehicle identification number may be used as the vehicle identification information. The basic information includes minimum information about the automobile 2 and the owner. The minimum information may include, for example, the model, type, color or exterior characteristics for identifying the automobile 2, the owner's contact information, address, contact phone number, etc. The minimum information may consist of some of the information listed above, or may include other information. However, from the perspective of protecting personal information, it is desirable that the information included in the owner database 22 be the minimum information necessary to identify the automobile 2 in an emergency and to respond quickly to rescue the occupants. Therefore, it is preferable that the owner database 22 not include, for example, health information about the owner or health information about passengers. The link information to the files 23 to 25 in the access restricted area 21 records the file names or paths of the files 23 to 25 in the access restricted area 21. The link information may record the file names or paths of a plurality of files.

[0030] 3, owner files 23 and 24 record access restriction information for each vehicle 2. The access restriction information for each vehicle 2 includes health information of the owner who uses the vehicle 2. The group file 25 records access restriction information for each occupant group, such as a family, who may be riding in the automobile 2. The access restriction information for each occupant group includes health information of each occupant in the occupant group. Health information about the owner and passengers may include, for example, their medical history, underlying conditions, chronic conditions, medical history, medications, and other health information. In addition to health information, the owner files 23, 24 or the group file 25 may also record personal information other than basic information, family information, and emergency contact information. Basically, the owner files 23, 24 or the group file 25 are encoded with a different password for each file and recorded in the memory 12. The password may be common for each vehicle 2 or each owner.

[0031] In this way, the memory area 20 of the server device 4 is provided with an area where access from the operator terminal 3 is restricted and an area where access is not restricted. General basic information as emergency-related information and detailed personal information are recorded in separate areas with different security levels based on access restrictions. Personal information recorded in the access-restricted area 21 is provided with high confidentiality, storage security, and a function to prevent unauthorized use. For example, even if an operator operates the operator terminal 3 to access the server device 4 when no emergency call has been made, the operator cannot check the contents (access restriction information) of the files 23 to 25 recorded in the access restriction area 21 of the server device 4. Furthermore, when the operator terminal 3 receives authentication information together with an emergency call from the vehicle 2, the operator can operate the operator terminal 3 to access the server device 4 and obtain access restriction information from the memory 12 of the server device 4. The operator can obtain the access restriction information recorded in the server device 4 as information related to the emergency.

[0032] FIG. 5 is an explanatory diagram of the control system 30 of the automobile 2 of FIG. The control system 30 of the automobile 2 in Figure 5 includes a vehicle ECU 31, a vehicle memory 32, a mobile communication device 33, a vehicle GNSS receiver 34, a vehicle timer 35, an acceleration sensor 36, an occupant monitoring system (DMS) 37, an in-vehicle camera 38, an in-vehicle speaker 39, an in-vehicle microphone 40, a vehicle display device 41, a vehicle operation device 42, and a vehicle network 43 to which these are connected. The vehicle network 43 may be a wired communication network for the automobile 2 that complies with, for example, a Controller Area Network (CAN) or a Local Interconnect Network (LIN). The in-vehicle network 43 may be a communication network such as a LAN, or a combination thereof. A wireless communication network may be included as part of the in-vehicle network 43. The vehicle GNSS receiver 34, vehicle timer 35, vehicle display device 41, vehicle operation device 42, in-vehicle speaker 39, and in-vehicle microphone 40 may be the same as those in the computer device 10 of Fig. 2. However, the vehicle operation device 42 is preferably a touch panel that is overlaid on the vehicle display device 41. The vehicle display device 41 may display, for example, the status of the autonomous driving of the automobile 2, an emergency call screen, etc.

[0033] The mobile communication device 33 establishes a communication path with the base station 6. The mobile communication device 33 serves as a vehicle communication unit and transmits and receives data to and from the communication device 17 of the operator terminal 3 via the base station 6 and the communication network 7.

[0034] The acceleration sensor 36 detects the acceleration of the automobile 2. The acceleration sensor 36 may detect the speed of the automobile 2. When the automobile 2 suddenly stops or collides, an acceleration higher than normal occurs.

[0035] The in-vehicle camera 38 captures an image of the interior of the automobile 2. The in-vehicle camera 38 may capture an image of only the owner of the automobile 2, or may capture an image of the entire interior of the automobile 2.

[0036] The occupant monitoring device 37 identifies the owner and passengers in the vehicle based on images captured by the in-vehicle camera 38 and monitors the condition of these occupants. Occupants may fall asleep, be distracted, or have an abnormal heart rate. The occupant monitoring device 37 may detect abnormalities in the health condition of the occupants based on the abnormal heart rate, etc.

[0037] The vehicle memory 32 stores programs and data.

[0038] The vehicle ECU 31 reads and executes a program from the vehicle memory 32. In this way, the vehicle ECU 31 functions as a control unit that controls the overall operation of the automobile 2, including driving control. A vehicle ECU 31 serving as a control unit of the automobile 2 controls the traveling of the automobile 2, such as automatic driving. For example, when the vehicle ECU 31 detects a collision because the detection value of the acceleration sensor 36 exceeds a threshold value, or when the occupant monitoring device 37 detects an abnormality or malfunction in the health condition of an occupant, the vehicle ECU 31 automatically sends an emergency call from the mobile communication device 33 to the operator terminal 3 based on these detections.

[0039] FIG. 6 is an explanatory diagram of the authentication information 50 recorded in the vehicle memory 32 of FIG. The vehicle memory 32 in FIG. 6 stores authentication information 50 for accessing the access restriction information stored in the memory 12 of the server device 4. Specifically, for example, the vehicle memory 32 in Figure 6 stores the vehicle identification information of the server device 4, the file name or path of a file related to the vehicle that is recorded in the access restricted area 21 of the server device 4, and the password for opening that file. In this way, information about files related to the vehicle itself is not recorded in the vehicle memory 32 of the automobile 2. Note that the vehicle memory 32 may record information about files related to the vehicle itself together with authentication information 50 for accessing the server device 4. When an emergency occurs in the automobile 2 and emergency information is to be sent from the mobile communication device 33 to the operator terminal 3, the vehicle ECU 31 may access the vehicle memory 32 to read the authentication information 50 and send it together with the emergency information as emergency-related information.

[0040] FIG. 7 is a timing chart showing the basic flow of an automatic emergency call in the entire automatic emergency call system 1 of FIG. 7 shows an automobile 2, an operator terminal 3, and a server device 4. Time flows from top to bottom. 7 shows an example of an emergency call when the car 2 has collided. Calls in other emergency situations are basically the same as in FIG.

[0041] In step ST1, the vehicle ECU 31 of the automobile 2 identifies the occupants in the automobile 2. The vehicle ECU 31 uses the occupant monitoring device 37, for example, to identify the occupants in the automobile 2.

[0042] In step ST2, the vehicle ECU 31 of the automobile 2 detects a collision of the automobile 2. For example, when the detection value of the acceleration sensor 36 exceeds a threshold value, the vehicle ECU 31 detects a collision of the automobile 2. The vehicle ECU 31 may detect a collision of the automobile 2 by predicting an unavoidable collision of the automobile 2.

[0043] In step ST3, the vehicle ECU 31 of the automobile 2 starts emergency call control based on the detection of a collision of the automobile 2.

[0044] In step ST4, the vehicle ECU 31 of the automobile 2 collects information from the automobile 2 as a vehicle. The vehicle ECU 31 may collect information about the state of the occupants after the collision is detected, for example, using the occupant monitoring device 37. The occupants may be injured or wounded or may be unconscious due to the collision.

[0045] In step ST5, the vehicle ECU 31 of the automobile 2 determines whether an emergency requiring an emergency call has occurred. The vehicle ECU 31 may determine whether an emergency requiring an emergency call has occurred based on, for example, the degree of impact caused by the collision, the consciousness or movement of occupants such as the owner, etc. If an emergency requiring an emergency call has occurred, the vehicle ECU 31 proceeds to step ST6. If an emergency requiring an emergency call has not occurred, the vehicle ECU 31 returns the process to step ST4. This allows the vehicle ECU 31 to continue monitoring the state after the collision is detected. After a predetermined period has elapsed, the vehicle ECU 31 may end this control instead of returning the process to step ST4.

[0046] In step ST6, the vehicle ECU 31 of the automobile 2 automatically transmits an emergency call. The vehicle ECU 31 uses the mobile communication device 33 to transmit an emergency call indicating that the automobile 2 is in an emergency situation due to the detection of an accident to the operator terminal 3.

[0047] In step ST7, the vehicle ECU 31 of the automobile 2 determines whether or not it is necessary to transmit information accompanying the emergency call. The vehicle ECU 31 may determine whether or not it is necessary to transmit information accompanying the emergency call, for example, based on the information collected in step ST4. If it is necessary to transmit the accompanying information, the vehicle ECU 31 proceeds to step ST8. If it is not necessary to transmit the accompanying information, the vehicle ECU 31 ends this control.

[0048] In step ST8, the vehicle ECU 31 of the automobile 2 acquires recorded information from the vehicle memory 32 of the automobile 2. The vehicle memory 32 stores authentication information 50 shown in FIG.

[0049] In step ST9, the vehicle ECU 31 of the automobile 2 automatically transmits information accompanying the emergency call. The vehicle ECU 31 transmits the authentication information 50 acquired in step ST8 to the operator terminal 3 via the mobile communication device 33. If possible, the vehicle ECU 31 may also transmit the information collected in step ST4 to the operator terminal 3. The vehicle ECU 31 uses the vehicle communication device 33 to transmit the authentication information 50 recorded in the vehicle memory 32 to the operator terminal 3 when an emergency occurs.

[0050] In step ST11, the CPU 11 of the operator terminal 3 determines whether or not an emergency call has been received. The operator terminal 3 receives the emergency call transmitted by the vehicle ECU 31 of the automobile 2 in step ST6. If an emergency call has not been received, the CPU 11 of the operator terminal 3 repeats this process. If an emergency call is received, the CPU 11 of the operator terminal 3 advances the process to step ST12.

[0051] In step ST12, the CPU 11 of the operator terminal 3 collects information related to the received emergency call.

[0052] In step ST13, the CPU 11 of the operator terminal 3 accesses the server device 4. The server device 4 transmits, to the operator terminal 3, information on the automobile 2 related to the emergency call from the owner database 22 in the memory area 20.

[0053] In step ST14, the CPU 11 of the operator terminal 3 acquires, from the server device 4, information related to the received emergency call. When collecting this related information, if the CPU 11 of the operator terminal 3 has received the authentication information 50 from the automobile 2 by the processing of step ST9, it transmits the authentication information 50 to the server device 4. The server device 4 opens the files 23 to 25 in the access restricted area 21 of the memory area 20 using the authentication information 50, and transmits the information contained in the files to the operator terminal 3. In this case, the CPU 11 of the operator terminal 3 can receive information on the owner and other occupants in addition to the basic information from the owner database 22, and acquire this as part of the emergency related information. In this manner, in this embodiment, the automobile 2 can function as a key device for authentication.

[0054] In step ST15, the CPU 11 of the operator terminal 3 outputs to the display device 15 the received emergency call and related information acquired from the server device 4 based on the emergency call. The operator can grasp the status of the emergency caused by the accident as well as the owner's health information from the display screen of the operator terminal 3. In addition to general information about the emergency, the operator can grasp health information such as the owner's medical history and determine the most appropriate dispatch unit.

[0055] In step ST16, the CPU 11 of the operator terminal 3 outputs a dispatch request to a dispatch unit that is determined to be the most suitable based on the relevant information and the like, based on the operation of the operation device 16 by the operator. When a dispatch request is made, the dispatch unit will rush to the location of vehicle 2 from which the emergency call was made, taking with them the emergency call and related information, and will carry out emergency rescue operations, etc. The dispatch unit can carry out more accurate rescue operations based on the owner's medical history and medication information. Furthermore, if the emergency-related information acquired from the server device 4 includes personal information such as the name, address, and telephone number of family members, the operator may call the family members to contact them.

[0056] FIG. 8 is a flowchart of an example of emergency call control of the automobile 2 that can be used for the automatic emergency call of FIG. The vehicle ECU 31 of the automobile 2 may repeatedly execute the emergency call control of FIG. 8 for the emergency call of FIG. 7, for example. The processing in steps ST4 and ST5 is the same as in Fig. 7. After step ST5, the vehicle ECU 31 advances the processing to step ST21.

[0057] In step ST21, the vehicle ECU 31 determines whether the emergency situation is due to an accident. For example, if the detection value of the acceleration sensor 36 exceeds a threshold value for determining that the accident is a minor collision, the vehicle ECU 31 determines that the emergency situation is due to an accident, and proceeds to step ST22. If the emergency situation is not due to an accident, the vehicle ECU 31 ends this control.

[0058] In step ST22, the vehicle ECU 31 determines whether the detection value of the acceleration sensor 36 is equal to or greater than the threshold for further emergency calls. The threshold for further emergency calls may be higher than the threshold for determining a minor collision, for example. If the detection value of the acceleration sensor 36 is not equal to or greater than the threshold for further emergency calls, the vehicle ECU 31 ends this control. If the detection value of the acceleration sensor 36 is equal to or greater than the threshold for further emergency calls, the vehicle ECU 31 proceeds to step ST23.

[0059] In step ST23, the vehicle ECU 31 determines whether or not the owner has responded. The vehicle ECU 31 may determine whether or not the owner has responded based on, for example, the detection result of the monitoring image of the occupant monitoring device 37 after a collision is detected. In this case, the vehicle ECU 31 may determine that the owner has not responded if there is no movement of the owner in the monitoring image. The vehicle ECU 31 may also call the owner using a synthesized voice from the in-vehicle speaker 39. In this case, the vehicle ECU 31 may determine that the owner has not responded if no clear response is obtained from the in-vehicle microphone 40. If the owner has not responded, the vehicle ECU 31 proceeds to step ST8. If the owner has responded, the vehicle ECU 31 proceeds to step ST25. The vehicle ECU 31 determines whether or not to transmit information accompanying the emergency call in step ST7 through the processes from step ST21 to step ST23.

[0060] In step ST8, the vehicle ECU 31 acquires recorded information from the vehicle memory 32 of the automobile 2. The authentication information 50 shown in Fig. 6 is recorded in the vehicle memory 32. Thereafter, the vehicle ECU 31 advances the process to step ST24.

[0061] In step ST24, unlike in FIG. 7, the vehicle ECU 31 automatically transmits the authentication information 50 acquired in step 8 together with the emergency call to the operator terminal 3 as information accompanying the emergency call. The mobile communication device 33 acquires the authentication information 50 recorded in the vehicle memory 32 from the vehicle ECU 31 and transmits the emergency call to the operator terminal 3. In this case, the operator terminal 3 can receive the authentication information 50 together with the emergency call. The operator terminal 3 does not need to perform processing to associate the separately received emergency call with the authentication information 50, as in the case where the emergency call and the authentication information 50 are received separately. Thereafter, the vehicle ECU 31 ends this control.

[0062] In step ST25, since the owner has responded, the vehicle ECU 31 automatically transmits only an emergency call to the operator terminal 3. In this case, the owner is conscious and can respond to subsequent calls from the operator. Thereafter, the vehicle ECU 31 ends this control.

[0063] In this way, when an emergency situation due to an accident occurs in the automobile 2, the vehicle ECU 31 determines the type of emergency situation, the level of the accident based on the collision, and whether or not the owner is conscious after the accident in order to determine whether or not it is necessary to send information accompanying the emergency call. For example, if the accident is a minor collision in which the impact is less than a threshold, the vehicle ECU 31 does not automatically send an emergency call to the operator terminal 3. In this case, the owner may manually make an emergency call. In addition, if the impact of the accident is greater than a threshold value and the owner is unconscious and unable to respond after the accident, the vehicle ECU 31 automatically sends the authentication information 50 recorded in the vehicle memory 32 to the operator terminal 3 along with an emergency call. Furthermore, even if the impact of the accident is greater than or equal to a threshold, if the owner is conscious enough to respond after the accident, the vehicle ECU 31 automatically transmits only an emergency call to the operator terminal 3.

[0064] In this embodiment, automatic transmission to the operator terminal 3 is switched based on the accident level and whether the owner is conscious after the accident, thereby preventing an unnecessary large number of emergency calls from being sent to the operator terminal 3. Furthermore, in this embodiment, if the accident level is high and the owner is unconscious after the accident, it is highly likely that the owner will be unable to make an emergency call, and therefore, it is possible to make it possible for the emergency call and accompanying information to be obtained at the operator terminal 3. The mobile communication device 33 of the automobile 2 can obtain the authentication information 50 recorded in the vehicle memory 32 and transmit it to the operator terminal 3 only when it is possible to confirm that an emergency has occurred in the automobile 2. The vehicle ECU 31 may also perform similar classification determination for emergency situations other than accidents. In this way, the automobile 2 controls the transmission of the authentication information 50, so that the access restriction information recorded in the memory 12 of the server device 4 is less likely to be inadvertently obtained by the operator terminal 3. A high level of security for the access restriction information is ensured.

[0065] As described above, in this embodiment, in the event of an emergency, the automobile 2 transmits the authentication information 50 recorded in the vehicle memory 32 of the automobile 2 along with an emergency call to the operator terminal 3. When the operator terminal 3 receives an emergency call from the automobile 2, it can acquire access restriction information from the memory 12 of the server device 4 as part of the emergency-related information, using the authentication information 50 received from the automobile 2. In this embodiment, there is no need to transmit multiple pieces of emergency-related information about the automobile 2 or its occupants, which tends to be a large amount of information, from the automobile 2 in which an emergency has occurred to the operator terminal 3. As a result, in this embodiment, the vehicle 2 in which an emergency has occurred can transmit to the operator terminal 3, through light-load communication processing with a short lead time, that the emergency has occurred and multiple pieces of information about the vehicle 2 and its occupants related to the emergency. The operator terminal 3 can reliably acquire multiple pieces of information about the vehicle 2 and its occupants related to the vehicle 2 in which the emergency has occurred, regardless of the state of the vehicle 2 after the emergency has occurred, and use this information in subsequent emergency response processing. For example, even if the vehicle 2 is in a state where some information cannot be acquired immediately due to an accident involving the vehicle 2, the operator terminal 3 can reliably acquire that information that can be used in emergency response. In this way, in this embodiment, it is possible to reduce the processing load, such as the communication load, of the vehicle 2 when sending an emergency report, while ensuring that the operator terminal 3 can acquire emergency-related information that is useful in emergency response. In this embodiment, the memory 12 of the server device 4 also stores access restriction information about the vehicle 2 or its occupants as part of multiple pieces of emergency-related information. Therefore, the operator terminal 3 can also obtain, from the memory 12 of the server device 4, information requiring access restriction management, such as the medical history, underlying illnesses, chronic illnesses, medications, and other health information of the vehicle 2's owner or passengers, personal information, family information, or emergency contact information, as part of the emergency-related information about the vehicle 2 or its occupants related to the vehicle 2 in which an emergency has occurred. Furthermore, in this embodiment, authentication information 50 for accessing the access restriction information is stored in the vehicle memory 32 of the vehicle 2 and transmitted to the operator terminal 3 only when an emergency has occurred in the vehicle 2. In this embodiment, by using the vehicle 2 as a key device and transmitting the information only when an emergency has occurred in the vehicle 2, the emergency-related information stored in the memory 12 of the server device 4 can be securely stored with high access restrictions that make it almost impossible to obtain under normal circumstances. This allows for confidentiality of information, secure storage, and prevention of unauthorized use.

[0066] [Second embodiment] Next, a second embodiment of the present invention will be described. This embodiment differs from the above-described embodiment in the emergency call control by the vehicle ECU 31 of the automobile 2. Other aspects are the same as the above-described embodiment, and therefore description thereof will be omitted.

[0067] FIG. 9 is a flowchart of emergency call control that can be carried out by the automobile 2 according to the second embodiment of the present invention. The vehicle ECU 31 of the automobile 2 repeatedly executes the emergency call control of FIG.

[0068] In step ST31, the vehicle ECU 31 determines whether to make an emergency call to the operator terminal 3. If a detection value of a level corresponding to an accident in the automobile 2 is detected by the acceleration sensor 36 or the like, the vehicle ECU 31 determines to make an emergency call to the operator terminal 3 and proceeds to step ST21. The vehicle ECU 31 may also determine to make an emergency call to the operator terminal 3 and proceed to step ST21 when an emergency situation other than a collision has occurred, such as when the occupant monitoring device 37 detects an abnormal state in the owner's pulse, blood pressure, posture, or the like. If it does not determine to make an emergency call to the operator terminal 3, the vehicle ECU 31 repeats this process until it determines to make an emergency call.

[0069] In step ST21, the vehicle ECU 31 determines whether the emergency call to the operator terminal 3 is due to an accident or not. If the emergency is due to an accident, the vehicle ECU 31 proceeds to step ST22. If the emergency is not due to an accident, the vehicle ECU 31 proceeds to step ST23.

[0070] In step ST22, the vehicle ECU 31 determines the level of impact of the accident. Accidents can be classified into categories ranging from minor collisions with low impact to major collisions with high impact. In the case of a minor collision, the vehicle body is unlikely to be damaged to the extent that the passenger compartment is significantly deformed, and it is estimated that in many cases, the injury level of the owner or other occupants will not be significant. In this case, it is considered that the occupants themselves can determine the need for an emergency call and manually execute an emergency call. In contrast, in the case of a major collision, the vehicle body may be damaged to the extent that the passenger compartment is significantly deformed, and it is estimated that the injury level of the owner or other occupants will be highly likely to be significant. In this case, the occupants may lose consciousness or be unable to move. Here, the vehicle ECU 31 may determine the level of impact of the accident by comparing the detection value of the acceleration sensor 36 with a determination threshold. If the detection value of the acceleration sensor 36 is equal to or greater than the threshold, the vehicle ECU 31 determines that the level of impact of the accident is large enough to be equal to or greater than the threshold, and proceeds to step ST8. If the detected value of the acceleration sensor 36 is not equal to or greater than the threshold value, the vehicle ECU 31 determines that the level of the impact of the accident is not so great as to be equal to or greater than the threshold value, and proceeds to step ST23.

[0071] In step ST23, the vehicle ECU 31 determines whether or not the owner has responded. The vehicle ECU 31 may, for example, call the owner using a synthesized voice from the in-vehicle speaker 39. In this case, the vehicle ECU 31 may determine that the owner has not responded if a clear response is not received from the in-vehicle microphone 40. If the owner has not responded, the vehicle ECU 31 proceeds to step ST8. If the owner has responded, the vehicle ECU 31 proceeds to step ST25. Through the processes from step ST21 to step ST23, the vehicle ECU 31 determines whether or not it is necessary to transmit information accompanying the emergency call in step ST7.

[0072] In step ST8, the vehicle ECU 31 acquires recorded information from the vehicle memory 32 of the automobile 2. The authentication information 50 shown in Fig. 6 is recorded in the vehicle memory 32. Thereafter, the vehicle ECU 31 advances the process to step ST24.

[0073] In step ST24, the vehicle ECU 31 automatically transmits the authentication information 50 acquired in step 8 together with the emergency call to the operator terminal 3 as information accompanying the emergency call. The mobile communication device 33 acquires the authentication information 50 recorded in the vehicle memory 32 from the vehicle ECU 31 and transmits the emergency call to the operator terminal 3. In this case, the operator terminal 3 can receive the authentication information 50 together with the emergency call. The operator terminal 3 does not need to perform processing to associate the separately received emergency call with the authentication information 50, as in the case where the emergency call and the authentication information 50 are received separately. Thereafter, the vehicle ECU 31 ends this control.

[0074] In step ST25, since the owner has responded, the vehicle ECU 31 automatically transmits only an emergency call to the operator terminal 3. In this case, the owner is conscious and can respond to subsequent calls from the operator. Thereafter, the vehicle ECU 31 ends this control.

[0075] As described above, in this embodiment, only when an emergency situation occurs in the automobile 2 due to an accident of a predetermined level or above, or when no response is received from the occupants of the automobile 2, the vehicle ECU 31 acquires the authentication information 50 recorded in the vehicle memory 32 from the vehicle ECU 31 via the mobile communication device 33 and transmits an emergency call to the operator terminal 3. This allows the vehicle ECU 31 to avoid acquiring the authentication information 50 recorded in the vehicle memory 32 and transmitting it together with the emergency call to the operator terminal 3 in other cases, including when an emergency call is manually made based on the operation of an occupant such as the owner of the automobile 2, or when the automobile 2 simply breaks down. In this embodiment, it is possible to prevent excessive transmission of the authentication information 50 recorded in the vehicle memory 32 of the automobile 2 as a key device to the operator terminal 3.

[0076] The above-described embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications and changes are possible within the scope of the gist of the invention.

[0077] FIG. 10 is an explanatory diagram of an authentication information table 60 that can be recorded in the vehicle memory 32 in place of the authentication information 50 of FIG. 10, the authentication information table 60 associates a single piece of vehicle identification information for the automobile 2 having the vehicle memory 32 with a plurality of pieces of authentication information, each of which is made up of the file name or path of a file related to the automobile 2 and a password for opening that file, the file name or path being stored in the restricted access area 21 of the server device 4. Specifically, the authentication information table 60 illustrates first authentication information made up of the file name or path of a file for the owner of the automobile 2 and a password for opening that file, and second authentication information made up of the file name or path of a file for the owner's family and a password for opening that file. In this case, the vehicle ECU 31 can transmit all of the authentication information in the authentication information table 60 to the operator terminal 3 via the mobile communication device 33 in the event of an emergency, but it is preferable to transmit only a portion of the authentication information in the authentication information table 60 to the operator terminal 3 depending on the result of the emergency situation assessment. For example, if an emergency situation occurs when only the owner is in the automobile 2, the vehicle ECU 31 only needs to send the first authentication information, which is part of the authentication information in the authentication information table 60, to the operator terminal 3 via the mobile communication device 33. In contrast, if an emergency situation occurs while the owner and his family are in the automobile 2, the vehicle ECU 31 simply transmits all of the authentication information in the authentication information table 60, that is, the first authentication information and the second authentication information, to the operator terminal 3 via the mobile communication device 33.

[0078] In this way, the vehicle memory 32 may store not only a single piece of authentication information for each vehicle 2, but also multiple pieces of authentication information for each occupant or group of occupants of the vehicle 2. In this case, the mobile communication device 33 selects at least some of the multiple pieces of authentication information stored in the vehicle memory 32 according to the situation of the vehicle 2 in which an emergency has occurred, and transmits the selected information to the operator terminal 3. This allows the operator terminal 3 to acquire the access restriction information stored in the memory 12 of the server device 4 in a state in which the access restriction information is limited to the extent required for responding to the emergency, according to the situation of the emergency in the vehicle 2.
