Specifically, the situation determination unit 88 determines whether the vehicle 2 can travel based on the vehicle state acquired by the situation acquisition unit 75 . In addition, based on the state of each passenger acquired by the situation acquisition unit 75, the situation determination unit 88 determines whether there is an injured person and whether all the passengers are injured (in other words, (whether or not there is an uninjured occupant). In this case, biological information is mainly used to determine whether or not the passenger is injured. Further, in the present embodiment, it is determined that the occupant is injured when the occupant is in a physical condition that makes it difficult for the occupant to steer the vehicle 2 or walk to the surrounding communication equipment.

Next, the operation of this embodiment will be described.
FIG. 4 is a flowchart of emergency call processing.
This emergency call processing is performed by the navigation device 18 when an emergency call request is output from the emergency call request device 12 . That is, when the emergency call request acquisition unit 74 of the navigation device 18 acquires an emergency call request from the emergency call request device 12, the communication failure determination unit 80 determines whether communication with the emergency call service center 4 is impossible ( Step Sa1).

If communication is possible (step S1: No), the emergency call control unit 77 notifies the emergency call to the emergency call service center 4 (step Sa2), and causes the navigation unit 70 to display a map showing the current position. instruct (step Sa3).
In the notification at step Sa2, transmission of notification data indicating the occurrence of the trouble and calling from the mobile phone 20 to the emergency notification service center 4 are performed. This call enables the operator of the emergency call service center 4 to communicate with the crew members, so that they can learn more about the current situation through the communication with the crew members. At this time, a map showing the current position is displayed on the display 57 of the navigation device 18 in step Sa3, so that the passenger can interact with the operator while grasping the current position and surroundings from the display.

On the other hand, if communication is not possible (step Sa1: Yes), the navigation device 18 executes processing for displaying the emergency contact information Ia on the display unit of the terminal according to the situation.
Specifically, first, the situation determination unit 88 determines whether or not the vehicle 2 can travel (step Sa4). If the vehicle 2 can travel (step Sa4: Yes), the selection unit 86 selects the display 57 of the navigation device 18 as the display unit of the terminal that displays the emergency contact information Ia (step Sa5).
On the other hand, when the vehicle 2 cannot run (step Sa4: No), the situation determination unit 88 determines whether or not there is an injured person (step Sa6), and if there is an injured person (step Sa6: Yes ), and it is determined whether or not all the passengers are injured (step Sa7).

If all the passengers are injured (step Sa7: Yes), the selection unit 86 selects the display 57 of the navigation device 18 as the terminal display unit for displaying the emergency contact information Ia (step Sa8).
If there is an uninjured occupant (step Sa6: No or step Sa7: No), the selector 86 displays the portable electronic device on the display of the terminal that displays the emergency contact information Ia. The display 54 of the mobile phone 20 is selected (step Sa9).

Then, the information display control unit 82 generates display data for the emergency contact information Ia (step Sa10), sends the display data to the terminal selected by the selection unit 86, and displays the emergency contact information Ia on the display unit of the terminal. is displayed (step Sa11).

More specifically, emergency telephones are generally installed at regular intervals of about 1 km or 500 m (200 m or 100 m in tunnels) on motorways and highways in Japan. Therefore, as shown in FIG. 5, when the current position is located on a road such as a highway on which emergency telephones are installed (hereinafter referred to as "emergency telephone installation road") (step Sb1: Yes), the information display control unit 82 selects the emergency telephone installed on the emergency telephone installation road as the communication equipment to be guided, and extracts the locations of a predetermined number of emergency telephones in order of proximity from the current position from the communication equipment information 84A (step Sb2).

On the other hand, if the current position is not on the road where the emergency telephone is installed (step Sb1: No), the information display control unit 82 displays the current position based on the current position and the communication equipment information 84A. It is determined whether or not there is a public telephone in the vicinity (within a predetermined range from the current position) (step Sb3).
If there is a public telephone (step Sb3: Yes), the surrounding public telephone is selected as the communication equipment to be guided, and the location of the public telephone near the current position is extracted from the communication equipment information 84A (step Sb4).
On the other hand, if the vehicle 2 is located in an area where there are no public telephones, such as in a mountainous area, and there is no public telephone nearby (step Sb3: No), the surrounding buildings where available communication equipment is installed (outdoor communication equipment such as an emergency telephone) is selected as the communication equipment to be guided, and locations of surrounding buildings are extracted from the communication equipment information 84A (step Sb5).

Further, the information display control unit 82 determines whether or not all passengers are injured (step Sb6). If all of the occupants are injured (step Sb6: Yes), the information display control unit 82 displays the current occupant conditions (seated condition, seated condition, and biometric information) are acquired (step Sb7).

Then, the information display control unit 82 stores the display data for displaying the emergency contact information Ia based on the location of the communication equipment extracted in the processing from steps Sb2 to Sb5 and the determination result of step Sb6 (occupant injury status). ) (step Sb8). After that, the information display control unit 82 returns to the process of step Sa11 of the above-described emergency call process. In this process, the information display control unit 82 causes the display unit selected by the selection unit 86 to display the emergency contact information Ia based on the display data.
