The same applies to the “introduction article”.

  The emergency response information storage unit F4 is a storage medium for storing emergency response information for supporting actions to be taken by the user in an emergency. FIG. 4 is an explanatory diagram illustrating an example of a storage state of emergency response information in the emergency response information storage unit F4. As shown in FIG. 4, emergency response information includes situation types in which emergency situations are classified for each feature, status items that are further classified into situation types, and response methods (headings of response methods) corresponding to each status. And details)), a situation determination element, and an emergency level. Here, it is preferable that the status items are classified in detail according to a situation that is expected to occur in an emergency. That is, for example, for the status type “failure”, it is preferable that various status items for each possible cause of failure are stored. In addition, the situation determination element is information indicating characteristics of an emergency situation, and in this example, for example, the situation item “engine failure” is set with a situation determination element “engine does not start”. To do.

  Note that the situation determination element in this example has a hierarchical structure linked to a plurality of situation items. That is, the plurality of situation determination elements have a relationship between a superordinate concept and a subordinate concept. That is, for example, the situation items “severe” and “mild” are set with a situation determination element such as a common situation determination element “having fever”. By adopting such a configuration, for example, by displaying a situation determination element in the form of a question to the user and having the user answer in Y / N, a response method according to the user's situation or the user It is possible to display information that may be useful to the user (for example, the cause of a vehicle failure estimated from the user's answer).

  The emergency level is an index indicating the urgency of the situation item. In this example, for each status item, “emergency level 3” which takes an action of notifying the emergency contact without waiting for an instruction from the user when the control unit C determines the status as an emergency level, “Emergency level 2” for reporting to contacts other than public organizations such as the police (for example, insurance companies) among contacts set as contacts, and “Emergency” for receiving instructions from users and reporting to emergency contacts “Level 1” is set.

  In this example, it is assumed that a plurality of response methods are set for one situation item in the emergency response information. In this example, the handling method includes “contact emergency contact”, “search for related facilities around”, “display first aid method”, and the like. In addition, the response method memorize | stored as emergency response information is not limited to this, For example, it is good also as a structure where the response method according to the passenger | crew number of the vehicle to which the navigation system 100 was attached is memorize | stored.

Here, the related facility genre indicates a facility genre related to the situation item. Further, it is assumed that an emergency contact address such as a telephone number or an e-mail address that can be contacted with the outside is set.

  In this example, it is assumed that the emergency response information and the emergency contact information can be edited by the user. Moreover, it is good also as a structure which displays the telephone number list | wrist (including telephone numbers, such as a car insurance and a car sales company) input by the user beforehand as an emergency contact so that selection is possible, and receives a user's selection.

  Next, the operation of the navigation device 10 of the present invention will be described with reference to the drawings. Note that a detailed description of processing not particularly related to the present invention may be omitted.

  FIG. 6 is a flowchart illustrating an example of a rescue support process executed by the navigation device 10. In the rescue support process, the navigation system 100 performs a process for performing an operation for assisting the user regarding a response that the user should take in an emergency.

  The rescue support process in this example is automatically started when the navigation device 10 is activated. The rescue support process may be started and stopped when the user presses a specific button, for example.

  In the rescue support process, the control unit C determines whether or not the shock detection information receiving unit 18 has received shock detection information indicating a numerical value higher than a predetermined threshold (step S101). If it is determined that the impact detection information indicating a numerical value higher than the predetermined threshold is received (Y in step S101), the control unit C executes a situation determination process (step S102). On the other hand, if it is determined that the impact detection information indicating a numerical value higher than the predetermined threshold has not been received (N in step S101), the control unit C receives a request for execution of the situation determination process by the user via the input device 70. It is determined whether or not (step S103). If it is determined that the execution request for the situation determination process has been received (Y in step S103), the control unit C transitions to step S102.

  By using the impact detection and input reception as triggers for the situation determination process, the navigation device 10 can detect an emergency (accident or failure) that the machine can detect and an emergency (disaster, occupant injury, or illness) that cannot be detected by the machine. Etc.).

  FIG. 7 is a flowchart illustrating an example of a situation determination process executed by the navigation device 10. In the situation determination process, a process for applying the emergency situation to the situation item included in the emergency response information (that is, a process for determining the emergency situation by specifying the situation item) is performed.

  In the situation determination process, first, the control unit C performs a process for generating a situation type selection screen and displaying it on the display screen of the image display device 61 by using the emergency screen generation unit 16 (step S201).

  FIG. 8 is an explanatory diagram illustrating an example of a situation type selection screen. As shown in FIG. 8, the situation type selection screen includes a situation type display area 101 that displays the situation type in a selectable manner, and other buttons that accept a display request for a situation type other than the situation type displayed in the situation type display area 101. And a return button 103 for switching the screen from the situation type selection screen to a normal menu screen, route guidance screen, or the like.

  When the situation type selection screen is displayed, the control unit C accepts selection of the situation type by the user (step S202). Here, for example, when the selection of the situation type due to the pressing of the part of the situation type “failure” displayed in the situation type display area 101 by the finger of the user is received (Y in step S202), the control unit C The emergency response information storage unit F4 is referred to, a situation determination element corresponding to the selected situation type is extracted, a situation determination element selection screen is generated by the emergency screen generation unit 16, and the display screen of the image display device 61 is displayed. (Step S203).

  FIG. 9 is an explanatory diagram illustrating an example of a situation determination element selection screen. As illustrated in FIG. 9, the situation determination element selection screen includes a situation determination element display area 201 that displays a situation determination element according to the selected situation type in a selectable manner, and emergency response information based on the selected situation determination element And a determination button 202 that accepts a narrowing request.

  When the situation determination element selection screen is displayed, the control unit C accepts selection of a determination element and a request for narrowing down emergency response information based on the selected determination element (step S204). Here, when the emergency response information narrowing request due to the user pressing the enter button 202 is accepted (Y in step S204), the control unit C is selected with reference to the emergency response information storage unit F4. It is determined whether or not there is a situation determination element having a lower concept relationship with the situation determination element (step S205). If it is determined that there is a situation determination element having a lower concept relationship (N in step S205), the control unit C displays a situation determination element having a lower concept relationship in the situation determination element display area 201 in a selectable manner. (Step S203).

  On the other hand, if it is determined that there is no situation determination element having a subordinate concept relationship (Y in step S205), the control unit C identifies the situation item (step S206), and transitions to step S104 of the rescue support process (FIG. 6). When the situation item cannot be specified only by selecting the situation item, for example, as shown in FIG. 10, the control unit C displays a situation item display by the emergency screen generation unit 16 so that a plurality of situation items can be selected. An emergency response information selection screen including the area 301 may be generated and displayed on the display screen.

  When the status item is specified in the status determination process, the control unit C determines whether or not the emergency level corresponding to the specified status item is lower than a predetermined value stored in the storage unit F (step S104). In this example, when the emergency level is lower than “emergency level 2”, that is, when “emergency level 1”, the control unit C determines that the emergency level is low (Y in step S104) and searches. The emergency response information storage unit F4 is searched by the unit 14, a response method that matches the specified situation item is extracted, an emergency response information display screen is generated by the emergency screen generation unit 16, and the image display device 61 Is displayed on the display screen (step S105). On the other hand, if the emergency level is not low, that is, if it is “emergency level 2” or “emergency level 3”, the control unit C determines that the emergency level is not lower than a predetermined value (N in step S104). Then, the process proceeds to step S107.

  FIG. 11 is an explanatory diagram illustrating an example of an emergency response information display screen. As shown in FIG. 11, the emergency response information display screen includes a response method display area 400 for displaying a response method stored as emergency response information. In this example, as shown in FIG. 11, the control unit C displays an emergency contact button 401, a peripheral related facility search button 402, and an inspection method display button 403 as response methods as emergency response information. A case will be described as an example.

  When the emergency response information display screen is displayed, the control unit C determines whether or not an emergency contact request has been accepted (step S106). In this example, when the emergency contact button 401 is pressed, the control unit C determines that an emergency contact request has been accepted (Y in step S106), and the search unit 14 stores the emergency contact information storage unit F5. By searching, an emergency contact address corresponding to the identified situation item is extracted, and the extracted contact address is notified of an emergency (step S107). That is, for example, when a telephone number is set as an emergency contact, the control unit C performs processing for making a voice call by the communication processing unit 17. At this time, based on the voice information stored in the storage unit F in advance, the control unit C reports an emergency situation, a description of the situation, the user's personal information, and the like to the emergency contact information. Note that, for example, when communication with the emergency contact is not established, the control unit C automatically searches for POI information corresponding to the emergency item by the search unit 14 and newly makes an emergency call. Good.

  When reporting to the emergency contact information, the control unit C receives the current position information from the own vehicle position positioning device 50 by the own vehicle position information receiving unit 12, and transmits the received current position information to the contact information (step) S108), the process here ends. In addition, it is good also as a structure which reports by audio | voice information also regarding present position information. Further, as the current position information, not only the coordinates of the current position but also the surrounding target facilities and road names, distances from famous intersections, and the like may be transmitted to the contact. Further, the control unit C may be configured to perform processing for displaying detailed current position information on the display screen of the image display device 61.

  On the other hand, if an emergency contact request is not received (N in step S106), the control unit C determines whether a search request for surrounding related facilities has been received (step S109). In this example, when the peripheral related facility search button 402 is pressed, the control unit C determines that a peripheral related facility search request has been accepted (Y in step S109), and refers to the emergency contact information storage unit F5. Then, the POI information around the current location is searched by the search unit 14 using the search target facility genre corresponding to the specified situation item as a keyword (step S110).

  When the POI information is searched, the control unit C displays a search result display screen showing the search result on the display screen of the image display device 61 (step S111), and accepts a destination selection by the user (step S112). In this example, the control unit C preferentially displays POI information indicating facilities and the like within a predetermined range from the current position.

  When the destination selection is accepted (Y in step S112), the control unit C performs a route search from the current position to the destination by the route search unit 11 (step S113). When the guidance route is derived by the route search, the control unit C stores the guidance route information, and performs the route guidance based on the stored guidance route information by the POI information guidance unit 15 (step S114). Exit.

  On the other hand, when the search request for surrounding related facilities is not received (N in step S109), the control unit C determines whether a response method display request is received (step S115). In this example, when the inspection method display button 403 is pressed, the control unit C determines that a response method display request has been received (Y in step S115), and refers to the emergency response information storage unit F4. The details of the handling method are extracted, the details of the extracted handling method are displayed on the display screen of the image display device 61 (step S116), and the processing here ends.

  As described above, in the embodiment described above, the current position of a moving body (for example, a vehicle) is displayed on the map on the display screen of the display device (for example, the image display apparatus 61). The navigation device 10 for guiding to the ground includes an emergency response information storage unit F4 that stores emergency response information indicating a response method according to an emergency situation, and determines a situation in which a mobile occupant is placed (For example, specifying a situation item by a determination element), searching for emergency response information matching the determined status (for example, status item), and outputting the searched emergency response information (for example, an image display device) 61), the occupant can effectively support taking an appropriate action according to the emergency situation.

  In other words, for example, if a rescue is necessary during a drive due to an accident, breakdown, or sudden illness of the passenger, even if the passenger (user) lacks calmness, Necessary actions can be taken when calling an ambulance.

Detected when performing emergency communication (for example, voice call or data transmission / reception), searching emergency contact information corresponding to the determined situation, and communicating with the contact indicated by the searched emergency contact information Since the current location is sent to the contact information, even if the user lacks calmness in an emergency, for example, the current location can be accurately communicated as the minimum necessary information in an emergency call. It made.

  Further, in the above-described embodiment, the navigation device 10 specifies the emergency level of the situation where the determined occupant is placed, and the emergency contact is made when the emergency level is a predetermined level or higher (for example, the emergency level 2 or higher). Since the prior information is searched and the emergency response information is searched when the emergency level is lower than the predetermined level, an appropriate response can be performed according to the emergency level.

  In other words, when the emergency level at which the operation by the occupant cannot be expected is high, the navigation device 10 makes an emergency call to the emergency contact information corresponding to the situation, thereby effectively supporting the response that the occupant should take. Will be able to. In addition, by configuring the navigation device 10 to execute the processing content corresponding to the emergency level, for example, “Wouldn't it be a serious injury and make an emergency call to the hospital and call an ambulance?” Such user anxiety can be resolved. In the embodiment described above, the case where emergency response information and emergency contact information are managed by different storage units has been described as an example. However, emergency contact information is included in the emergency response information. It may be managed in a form.

  In the above-described embodiment, the navigation device 10 includes the POI information storage unit F3 that stores POI information including guidance target object specifying information (for example, facility name) indicating the guidance target object (for example, facility). The emergency contact information includes a search target facility type (for example, search target facility genre) according to the emergency situation, searches for POI information according to the search target type, and specifies a specific condition (for example, from the current position). The POI information satisfying the condition (positioned within a predetermined range) is preferentially displayed on the display screen (for example, the display screen of the image display device 61), so that it is possible to guide an appropriate facility according to the situation. become able to.

  In the above-described embodiment, the case where the navigation device 10 preferentially displays the POI information close to the current position of the vehicle has been described. However, the POI information search method is not limited to this. When the situation is “injury” or “illness”, it is possible to preferentially guide the POI information indicating a hospital located near the passenger's home in consideration of subsequent hospital visits. Further, as a search condition, “presence / absence of parking lot”, “position in the traveling direction of the vehicle”, and the like may be associated with the situation items.

  Although not specifically mentioned in the above-described embodiment, when the navigation device 10 makes an emergency call (see step S107 in FIG. 6), the control unit C refers to the map information storage unit F1 and currently Determine the road type of the location and the required road manager (for example, a public corporation for highways, a national highway office for national roads, a prefectural office for prefectural roads, a municipal office for city roads, etc.) It is good also as a structure which guides the contact information. By adopting such a configuration, for example, it becomes possible to provide an appropriate contact information to the user in the event of a disaster (impossible of traffic due to road flooding, road collapse, landslide, etc.). Further, the navigation device 10 is configured to contact the road manager, so that it is possible to assist the road manager in quickly responding to a disaster or the like.

  INDUSTRIAL APPLICABILITY The present invention is industrially useful in an industry that handles devices that provide vehicle route guidance, and is also useful in the electrical appliance market such as a car navigation device that can display an electronic map.
