An information processing apparatus that is one aspect of the present disclosure includes a control unit. The control unit acquires information about an abnormality of the vehicle, and in response to acquiring the information about the abnormality, outputs information about data obtained by satellite observation of a predetermined range including the position of the vehicle. Execute.

Here, by observing the earth's surface with artificial satellites, it is possible to detect disasters such as landslides, heavy snow, or flooding. However, it takes time to analyze the data sent from the satellite. For example, it takes time to determine whether or not a disaster has occurred on the entire surface of the earth based on observation data obtained from satellites, because it is necessary to analyze an enormous amount of data. Further, even if it is detected that a disaster has occurred, more time is required to determine whether or not there are victims there. Therefore, when there is actually a victim, it takes time to be rescued.

Here, by preferentially analyzing the observation data of a place where the vehicle is highly likely to be damaged, it is possible to expedite the rescue of the victim. Therefore, the control unit acquires information about the abnormality of the vehicle. A vehicle abnormality is, for example, an abnormality that occurs in a vehicle due to a disaster. The information about vehicle abnormality includes, for example, information about an event that occurs in the vehicle when the vehicle is involved in a disaster. For example, in a vehicle equipped with an automatic transmission, engine stall is less likely to occur. On the other hand, when a vehicle is damaged, the exhaust pipe of the engine is clogged with sand, water, snow, or the like, resulting in engine stall. Therefore, if the engine stalls even though the vehicle is in the running state, it can be considered that the vehicle has an abnormality.

In this way, when information about vehicle abnormality is acquired, it can be considered that the vehicle has been involved in a disaster or the like. Accordingly, the control unit outputs information regarding data obtained by satellite observation of a predetermined range including the position of the vehicle in response to acquisition of information regarding the abnormality. The predetermined range may be, for example, a range necessary for examining whether or not a secondary disaster will occur, or a range observable by a satellite (may be an imageable range). good. Alternatively, it may be a range that can be searched by a rescue team. In this way, by outputting information on the data observed by the satellite using the occurrence of an abnormality in the vehicle as a trigger, the information on the observed data in the range where the vehicle is likely to be involved in the disaster is promptly provided. be able to.

Information related to observed data may be, for example, the observed data itself (raw data), information that can identify the location where a disaster occurred, or data that visualizes the shape of the earth's surface. good too. Alternatively, for example, it may be information about the results of comparing current observation data with past observation data. It may also contain information for notifying that a disaster has occurred. Information indicating the position of the vehicle may also be output together. Outputting information includes, for example, transmitting information or displaying information on a display or the like.

In this way, by determining the range for analyzing the observation data of the satellite based on the position information transmitted from the vehicle, it is possible to preferentially analyze the data of the location where the vehicle was involved in the disaster. This makes it easier, for example, for the rescue team to grasp the disaster situation, so that quicker rescue becomes possible.

Embodiments of the present disclosure will be described below based on the drawings. The configurations of the following embodiments are examples, and the present disclosure is not limited to the configurations of the embodiments. Moreover, the following embodiments can be combined as much as possible.

<First embodiment>
FIG. 1 is a diagram showing a schematic configuration of a system 1 according to this embodiment. A system 1 includes a vehicle 10 , a user terminal 20 , a server 30 and an artificial satellite 40 . The system 1 is a system that observes a predetermined range including the position of the vehicle 10 with a satellite 40 and provides information on observation data to the user terminal 20 in response to acquiring information about anomalies from the vehicle 10 . Further, when the server 30 determines that a disaster has occurred, the server 30 transmits the location information of the damaged vehicle 10 to the user terminal 20 .

Vehicle 10, user terminal 20, server 30, and artificial satellite 40 are interconnected by network N1. The network N1 is, for example, a worldwide public communication network such as the Internet, and may be a WAN (Wide Area Network) or other communication networks. The network N1 may also include a telephone communication network such as a mobile phone, or a wireless communication network such as Wi-Fi (registered trademark). A plurality of vehicles 10, user terminals 20, and artificial satellites 40 may exist.

The artificial satellite 40 is an artificial satellite that observes the state of the earth's surface. The artificial satellite 40 is, for example, a synthetic aperture radar satellite (SAR satellite). The artificial satellite 40 can observe the altitude of the ground surface and the state of the ground surface by irradiating the ground surface with radio waves. For example, the artificial satellite 40 can observe the altitude of the ground surface irradiated with radio waves by using the reflected waves of the radio waves irradiated on the ground surface. Here, the altitude of the ground surface changes at the point where the landslide occurred. Therefore, past observation data and current observation data are compared, and if there is a difference in elevation of the ground surface at the same point, it can be determined that a landslide has occurred, for example. Based on this observation data, it is also possible to detect the type of disaster, the area where the disaster occurred, and the like. As another method, the satellite 40 may have a camera, and the image data obtained by capturing the surface of the earth may be transmitted to the server 30 .

The artificial satellite 40 transmits observation data to the server 30 via the network N1. Satellite 40 can also observe the position or range requested by server 30 and transmit the observation data to server 30 . Moreover, the satellite 40 can also observe a predetermined range at a predetermined timing and transmit the data to the server 30 .

Vehicle 10 is a connected vehicle that can connect to network N<b>1 and transmit predetermined information to server 30 . Vehicle 10 is driven by an engine, for example. In the present embodiment, the engine-driven vehicle 10 is described as an example because the engine stall is used as a trigger. However, when using other triggers, the engine is not an essential component. For example, in the case where a sensor attached to the vehicle detects vibration and the sensor detection value is transmitted from the vehicle 10 to the server 30 as information regarding an abnormality, the vehicle 10 does not need to be driven by the engine.

A user terminal 20 is a terminal used by a user. This user is, for example, a rescue worker who rescues a victim when a disaster occurs. The user terminal 20, for example, displays the information transmitted from the server 30 on the screen, thereby presenting to the user the location of the victims and the area where the disaster occurred.

Server 30 determines whether or not an abnormality has occurred in vehicle 10 based on information transmitted from vehicle 10 . Then, when it is determined that an abnormality has occurred in the vehicle 10 , a command is transmitted to the satellite 40 to observe a predetermined range including the current position of the vehicle 10 . Based on the data transmitted from the artificial satellite 40, it is determined whether or not a disaster has occurred. When it is determined that a disaster has occurred, information for requesting rescue is transmitted to the user terminal 20 .

Next, hardware configurations of the vehicle 10, the user terminal 20, the server 30, and the artificial satellite 40 will be described with reference to FIG. FIG. 2 is a block diagram schematically showing an example of each configuration of the vehicle 10, the user terminal 20, the server 30, and the artificial satellite 40 that constitute the system 1 according to this embodiment.

These are interconnected by a bus. Note that the processor 31 is an example of a control unit. Also, the main storage unit 32 and the auxiliary storage unit 33 are examples of a storage unit.

The processor 31 is a CPU (Central Processing Unit), a DSP (Digital Signal Processor), or the like. The processor 31 controls the server 30 and performs various information processing operations. The main storage unit 32 is RAM (Random Access Memory), ROM (Read Only Memory), or the like. The auxiliary storage unit 33 is an EPROM (Erasable Programmable ROM), a hard disk drive (HDD, Hard Disk Drive), a removable medium, or the like. The auxiliary storage unit 33 stores an operating system (OS), various programs, various tables, and the like. The processor 31 loads the program stored in the auxiliary storage unit 33 into the working area of the main storage unit 32 and executes it, and through the execution of this program, each component is controlled. As a result, the server 30 implements a function that meets a predetermined purpose. However, some or all of the functions may be realized by hardware circuits such as ASIC and FPGA. The main storage unit 32 and the auxiliary storage unit 33 are computer-readable recording media. Note that the server 30 may be a single computer, or may be a combination of a plurality of computers. Information stored in the auxiliary storage section 33 may also be stored in the main storage section 32 . Information stored in the main storage unit 32 may also be stored in the auxiliary storage unit 33 .

The communication unit 34 is means for communicating with the vehicle 10, the user terminal 20, and the artificial satellite 40 via the network N1. The communication unit 34 is, for example, a LAN (Local Area Network) interface board or a wireless communication circuit for wireless communication. A LAN interface board and a wireless communication circuit are connected to the network N1. Note that communication with the artificial satellite 40 may be performed via a computer that manages the artificial satellite 40 .

Next, the user terminal 20 will be explained. The user terminal 20 is, for example, a small computer such as a smart phone, a mobile phone, a tablet terminal, a personal information terminal, a wearable computer (such as a smartwatch), or a personal computer (PC). The user terminal 20 has a processor 21 , a main storage section 22 , an auxiliary storage section 23 , an input section 24 , a display 25 and a communication section 26 . These are interconnected by a bus. The processor 21, the main storage unit 22, and the auxiliary storage unit 23 are the same as the processor 31, the main storage unit 32, and the auxiliary storage unit 33 of the server 30, so description thereof will be omitted.

The input unit 24 is means for receiving an input operation performed by a user, and is, for example, a touch panel, a mouse, a keyboard, or a push button. The display 25 is means for presenting information to the user, and is, for example, an LCD (Liquid Crystal Display) or an EL (Electroluminescence) panel. The input unit 24 and the display 25 may be configured as one touch panel display.

The communication unit 26 is communication means for connecting the user terminal 20 to the network N1. The communication unit 26 is, for example, a mobile communication service (for example, a telephone communication network such as 5G (5th Generation), 4G (4th Generation), 3G (3rd Generation), LTE (Long Term Evolution)), Wi-Fi (registration (trademark), Bluetooth (registered trademark), etc., to communicate with other devices (for example, the server 30, etc.) via the network N1.

The vehicle 10 has an in-vehicle device 50 , an engine 51 , an ECU 52 , a sensor group 53 , an IG switch 54 and a GPS device 55 . These components are interconnected by buses of the on-board network.

The in-vehicle device 50 is a device that provides information to the server 30 . The in-vehicle device 50 may be a car navigation device, an infotainment device, or a head unit. The in-vehicle device 50 has a function of transmitting to the server 30 information detected by a sensor group 53 to be described later, the activation state of the vehicle 10 , and information acquired by the GPS device 55 .

The in-vehicle device 50 has a configuration of a computer. The in-vehicle device 50 has a processor 11 , a main storage section 12 , an auxiliary storage section 13 and a communication section 14 . These are interconnected by a bus. The processor 11, the main storage unit 12, and the auxiliary storage unit 13 are the same as the processor 31, the main storage unit 32, and the auxiliary storage unit 33 of the server 30, and the communication unit 14 is the same as the communication unit 26 of the user terminal 20. , so the description is omitted.

Engine 51 is an engine for driving vehicle 10, and is, for example, an internal combustion engine such as a gasoline engine or a diesel engine. The ECU 52 controls the engine 51 based on detection values from a sensor group 53, which will be described later. The ECU 52 can be configured as a computer having a processor, a main memory, and an auxiliary memory similar to the in-vehicle device 50 .

The sensor group 53 includes, for example, a sensor that detects the running state of the vehicle 10, a sensor that detects the rotational speed of the engine 51, and the like. A sensor that detects the running state of the vehicle 10 includes, for example, a speed sensor, an acceleration sensor, an accelerator opening sensor, or a brake switch. A sensor that detects the rotation speed of the engine 51 includes, for example, a rotary encoder.

The IG switch 54 is a switch for starting the vehicle 10 or stopping the function of the vehicle 10 when pressed by the passenger. The state in which the vehicle 10 is activated by pressing the IG switch 54 by the passenger is called the IG ON state, and the state in which the vehicle 10 stops functioning by pressing the IG switch 54 again by the passenger is called the IG OFF state. For example, when the passenger presses the IG switch 54 while depressing the brake pedal, the vehicle 10 is started and the engine 51 is started. After that, by pressing the IG switch again, the engine 51 stops and the functions of the vehicle 10 stop.

The GPS device 55 acquires position information and the current time of the vehicle 10 based on radio waves from GPS (Global Positioning System) satellites. Any position information acquisition device and time information acquisition device other than the GPS device 55 can be employed as long as similar information can be acquired. For example, as the position information acquisition device, a positioning device using a satellite positioning system other than GPS, or a positioning device using a multi-base station positioning method may be employed.

The artificial satellite 40 has an observation device 41 such as a camera or a synthetic aperture radar to observe the state of the earth's surface. Further, the artificial satellite 40 has a computer including a processor, a main storage section, an auxiliary storage section, and a communication section similar to the server 30 .

Next, functional components of the vehicle 10, the user terminal 20, and the server 30 will be described. FIG. 3 is a diagram showing an example of functional components of the vehicle 10, the user terminal 20, and the server 30 according to the embodiment. The server 30 includes a control unit 301, a user information DB 311, a vehicle information DB 312, and an observation information DB 313 as functional components. The processor 31 of the server 30 executes the processing of the control section 301 according to the computer program on the main storage section 32 .

The user information DB 311, the vehicle information DB 312, and the observation information DB 313 are constructed by managing data stored in the auxiliary storage unit 33 by a database management system (DBMS) program executed by the processor 31. database.

The user information DB 311 stores information about people who rescue people when a disaster occurs. Specifically, the user information DB 311 stores the relationship between the area where the disaster occurred, the type of disaster, and the contact information of the rescue team. Details of the user information DB 311 will be described later.

The control unit 301 determines the position of the ground surface to be observed based on information transmitted from the vehicle 10 . The information transmitted from the vehicle 10 is information that can determine that the vehicle 10 is in an activated state and the engine 51 has stopped. Specifically, it is the information that enables determination that the rotation speed of the engine 51 has become 0 even though the IG switch 54 has not been pressed again after the IG switch 54 has been pressed and the engine 51 has been activated. . From the vehicle 10, for example, information indicating whether the engine is in the IG ON state or the IG OFF state, and information regarding the rotation speed of the engine 51 may be transmitted at predetermined time intervals. Then, based on the information, the control unit 301 may determine whether or not the rotation speed of the engine 51 has become 0 while the IG is on. The information transmitted from the vehicle 10 also includes position information. The control unit 301 causes the vehicle information DB 312 to store the information received from the vehicle 10 . The vehicle information DB 312 is a database that stores the position of the vehicle 10, the state of the vehicle 10, and the like, and the details will be described later.

Alternatively, when the rotation speed of the engine 51 becomes 0 while the IG is on, the vehicle 10 may notify the server 30 to that effect. Upon receiving this notification, control unit 301 determines that an abnormality has occurred in vehicle 10 .

When the control unit 301 determines that the rotation speed of the engine 51 has become 0 while the vehicle 10 is in the IG ON state, the control unit 301 determines a predetermined range including the current position of the vehicle 10 based on the position information of the vehicle 10. Send commands to satellites 40 to observe. Then, when the observation data of the predetermined range is received from the artificial satellite 40, the control unit 301 determines whether or not a disaster has occurred, for example, by comparing it with the past observation data of the same range. For example, if there are places where the altitude is decreasing and places where the altitude is increasing, it is considered that a landslide has occurred. Also, if the altitude is high overall, it may be considered that heavy snowfall or flooding is occurring. Also, for example, by combining data received from a server distributing weather information, it is possible to assume that flooding occurs in areas where it is raining, and disasters due to heavy snow occur in areas where it is snowing. good. Note that past observation data is stored in the observation information DB 313 . Observation data is stored in the observation information DB 313 in association with the observed range and date and time. Details of the observation information DB 313 will be described later.

If the control unit 301 determines that a disaster has occurred at the current position of the vehicle 10, it can be considered that the vehicle 10 has become involved in the disaster and that an abnormality has occurred in the vehicle 10. That is, there is a high possibility that the engine 51 stopped because the vehicle 10 was damaged. Therefore, the control unit 301 refers to the user information DB 311 to identify the current position of the vehicle 10 and the user terminal 20 of the rescue worker corresponding to the type of disaster, and requests rescue to the user terminal 20. Send information for This information includes the location of the vehicle 10 and the type of disaster. Also, if there is a risk of a secondary disaster, information to that effect may be transmitted to the user terminal 20 . For example, if there is a place where the altitude gradually changes within a predetermined range, there is a risk that a landslide will occur and rescue workers will be involved. Also, for example, if a river is dammed up with earth and sand and there is a natural dam, there is a risk of a secondary disaster due to the collapse of the dam. Therefore, if a natural dam occurs at a place higher in altitude than the vehicle 10, it can be determined that there is a risk of a secondary disaster. Therefore, the control unit 301 may determine whether or not there is a risk of a secondary disaster, and send the determination result to the user terminal 20 .

FIG. 4 is a diagram exemplifying the configuration of a user information table stored in the user information DB 311. As shown in FIG. The user information table has user terminal, area, and type fields. The user terminal field is a field in which information on the user terminal 20 corresponding to the rescue team is entered. The user terminal field may store, for example, the ID of the user terminal 20 or information about the connection destination. The region field stores information about the region where the rescue team responds to rescue. The region field stores information based on, for example, administrative divisions or mesh codes. The type field stores information about the types of disasters that rescue teams deal with. For example, information is stored that can be used to determine which of flood damage, landslides, or heavy snow is to be dealt with.

FIG. 5 is a diagram illustrating the configuration of a vehicle information table stored in the vehicle information DB 312. As shown in FIG. Information stored in the vehicle information DB 312 is acquired from the vehicle 10 at predetermined time intervals. The vehicle information table has fields of vehicle ID, date and time, position, IG, and engine speed. An identification code (vehicle ID) unique to the vehicle 10 is stored in the vehicle ID field. Information relating to the date and time when the vehicle 10 sent the information is stored in the date and time field. The location field stores the location information of the vehicle 10 acquired by the GPS device 55 of the vehicle 10 . The IG field stores information for determining whether the IG is on or off. Information about the rotational speed of the engine 51 is stored in the engine speed field.

FIG. 6 is a diagram exemplifying the configuration of an observation information table stored in the observation information DB 313. As shown in FIG. The information stored in the observation information DB 313 is acquired from the artificial satellite 40 at predetermined time intervals or acquired from the artificial satellite 40 in response to an instruction from the control unit 301 . For example, when no disaster has occurred, the artificial satellite 40 sequentially observes the earth's surface and transmits the observation data to the server 30 . The observation information table has fields of range, date and time, and observation data. The Range field stores information about the observed range. Information about the observed range can include, for example, information about mesh codes, information about administrative divisions, or information about coordinates. The date and time field stores information about the date and time when the artificial satellite 40 observed the earth's surface. Observation data may be entered in the observation data field, or information indicating the location where the observation data is stored may be entered.

Next, vehicle 10 includes control unit 101 as a functional component. The processor 11 of the in-vehicle device 50 executes the processing of the control section 101 according to the computer program on the main storage section 12 . The control unit 101 transmits information enabling determination of the IG ON state or the IG OFF state, the rotational speed of the engine 51, and position information to the server 30 at predetermined time intervals. Alternatively, when the rotation speed of the engine 51 becomes 0 while the IG is on, the control unit 101 may transmit information to that effect to the server 30 together with the positional information.

Next, the user terminal 20 includes a control section 201 as a functional component. The processor 21 of the user terminal 20 executes the processing of the control section 201 according to the computer program on the main storage section 22 . When the control unit 201 receives the information regarding the request for help from the server 30, the control unit 201 causes the display 25 to display an image corresponding to the information. The control unit 201 causes the display 25 to display, for example, observation data that visualizes the extent of the disaster and the position of the damaged vehicle 10 .

Next, a process of requesting rescue by the server 30 will be described. FIG. 7 is a flowchart of a process of requesting help by the server 30 according to the embodiment. The processing shown in FIG. 7 is executed in the server 30 at predetermined time intervals for each vehicle. Note that the user information DB 311, the vehicle information DB 312, and the observation information DB 313 are assumed to store necessary information.

In step S101, the control unit 301 determines whether or not the IG is on and the rotation speed of the engine 51 is zero based on vehicle information received from the vehicle 10 at predetermined time intervals. That is, it is determined whether or not the vehicle 10 has an abnormality. The control unit 301 reads the latest vehicle information corresponding to the vehicle 10 from the vehicle information DB 312 and determines whether or not the IG is on and the rotational speed of the engine 51 is zero. If an affirmative determination is made in step S101, the process proceeds to step S102, and if a negative determination is made, this routine is terminated.

In step S<b>102 , the control unit 301 determines whether or not the IG is on and the rotation speed of the engine 51 is greater than zero based on the vehicle information received from the vehicle 10 last time. That is, it is determined whether or not the vehicle 10 was normal in the previous vehicle information. The previous vehicle information is read from the vehicle information DB 312 . If the determination in step S102 is affirmative, the process proceeds to step S103, and if the determination is negative, this routine is terminated.

In step S103, the control unit 301 requests the artificial satellite 40 to transmit observation data. At this time, the control unit 301 generates a command to transmit data obtained by observing a predetermined range including the latest position information of the vehicle 10 stored in the vehicle information DB 312 .

In step S<b>104 , the control unit 301 receives observation data from the artificial satellite 40 . Next, in step S<b>105 , the control unit 301 analyzes the observation data received from the artificial satellite 40 . For example, the previous observation data of the same range may be read from the observation information DB 313 and compared with the observation data received this time to generate a difference image to visualize the occurrence of a disaster. Also, the control unit 301 may specify the range where the disaster occurs. Furthermore, it may be determined whether or not the situation is such that a secondary disaster may occur. Note that it is also possible to determine the occurrence of a disaster or the like using only newly received observation data without using previous observation data. A well-known technique can also be used for the method of determining the occurrence of a disaster or the like.

In step S<b>106 , the control unit 301 determines whether or not a disaster has occurred within a predetermined range including the current position of the vehicle 10 . This determination is made based on the analysis result in step S105. If an affirmative determination is made in step S106, the process proceeds to step S107, and if a negative determination is made, this routine is terminated.

In step S<b>107 , the control unit 301 generates information for requesting help and transmits it to the user terminal 20 . This information includes information regarding the position of the vehicle 10, the area where the disaster has occurred, and whether or not there is a possibility of a secondary disaster occurring. The area where the disaster has occurred may be provided as image data obtained by visualizing the data observed by the artificial satellite 40, for example. At this time, the area where the disaster occurred and the area where the disaster did not occur may be displayed in different colors. The image data may include information that allows the position of the vehicle 10 to be known. Then, the control unit 301 extracts the user terminal 20 of the rescue team corresponding to the current position of the vehicle 10 from the user information DB 311 and transmits information for requesting rescue to the user terminal 20 .

As described above, according to the present embodiment, the occurrence of a disaster is determined using the occurrence of an abnormality in the vehicle 10 as a trigger, so that the occupants of the vehicle 10 involved in the disaster can be promptly rescued. For example, even if a disaster occurs, it is difficult to determine whether the vehicle 10 is involved in the disaster based only on observation data from the satellite 40 . Moreover, even if the area where the disaster occurs is specified, the occurrence of the disaster cannot be detected unless the area observed by the artificial satellite 40 is correct. Therefore, the occurrence of a disaster cannot be detected until the satellite 40 observes the affected area. Therefore, even if there is a damaged vehicle 10, it takes time to rescue the occupants.

On the other hand, in the present embodiment, if there is an abnormality in the vehicle 10, there is a high possibility that the vehicle 10 is damaged. there is As a result, it is possible to preferentially observe a range in which a disaster may occur, so that the occurrence of a disaster can be detected at an early stage. Further, when the engine 51 stops even though the vehicle 10 is in the IG ON state, it is determined that the vehicle 10 requires rescue because it is clear that a person is on board the vehicle 10. be able to. Therefore, it is possible to suppress wasting time searching for an unmanned vehicle. In addition, since the position of the vehicle 10 is also identified, the occupant can be rescued more quickly. Furthermore, when there is a risk of a secondary disaster occurring, the fact is notified to the rescuers, so that the rescuers can be prevented from being involved in the secondary disaster.

<Other embodiments>
The above embodiment is merely an example, and the present disclosure can be modified as appropriate without departing from the scope of the present disclosure.

The processes and means described in the present disclosure can be freely combined and implemented as long as there is no technical contradiction.

Also, the processing described as being performed by one device may be shared and performed by a plurality of devices. Alternatively, processes described as being performed by different devices may be performed by one device. In a computer system, it is possible to flexibly change the hardware configuration (server configuration) to implement each function.

For example, the user terminal 20 may have part or all of the functions of the server 30 . For example, in the above description, the server 30 determines the occurrence of a disaster, but as an alternative method, observation data may be transmitted from the server 30 to the user terminal 20, and the user terminal 20 may determine the occurrence of a disaster. .

In this case, the processes of steps S105 and S106 of FIG. 7 are not executed by the server 30, and observation data is transmitted to the user terminal 20 instead of the rescue request in step S107. Then, in the user terminal 20, the control unit 201 executes processing corresponding to steps S105 and S106.

Further, in the above description, it is determined that the vehicle 10 has an abnormality when the IG is on and the rotation speed of the engine 51 is 0, but the determination condition is not limited to this. For example, it may be determined whether or not the vehicle 10 is damaged by analyzing the image of the drive recorder. Alternatively, it may be determined whether or not the vehicle 10 has been damaged using the detection values of the sensor group 53 .

It should be noted that if a plurality of vehicles 10 malfunction at the same time, it is considered that a large-scale disaster has occurred. In this case, satellites 40 may preferentially observe areas where the density of vehicles 10 is high.

The present disclosure can also be implemented by supplying a computer program implementing the functions described in the above embodiments to a computer, and reading and executing the program by one or more processors of the computer. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. A non-transitory computer readable storage medium is any type of disk such as, for example, a magnetic disk (floppy disk, hard disk drive (HDD), etc.), an optical disk (CD-ROM, DVD disk, Blu-ray disk, etc.), Including read only memory (ROM), random access memory (RAM), EPROM, EEPROM, magnetic cards, flash memory, optical cards, any type of medium suitable for storing electronic instructions.
