Description

  The present disclosure relates to an emergency notification system and an emergency notification method.

  Traditionally, automobiles have been used exclusively as a vehicle for carrying passengers or luggage. The widespread use of automobiles has brought great benefits to its passengers and shippers, while many public spaces such as trains and shopping streets have been lost. At present, there are many cases where the beneficiaries are biased by the use of automobiles, and it is difficult to say that automobiles are being used as a means for social contribution.

  However, in recent years, with the increasing functionality of automobiles, the possibility of utilizing automobiles as a means for contributing to society is being newly found. For example, there are cases in which automobiles constitute a part of social infrastructure, for example, hybrid cars and electric cars supply power as lifelines when natural disasters such as earthquakes occur. Thus, in the event of an accident or natural disaster, the role of automobiles as a means for social contribution that is beneficial to people other than passengers is being reviewed.

In one example, the roadside machine 3 is an ITS spot compatible with ETC 2.0. For the sake of brevity, the first roadside machine 3-1 and the second roadside machine 3-2 are described as separate roadside machines 3, but the first roadside machine 3-1 is described as an embodiment. The same roadside machine 3 may be sufficient as 3-1 and the 2nd roadside machine 3-2.

  The cloud computer 4 communicates with the roadside device 3 bidirectionally via the Internet. In one example, the cloud computer 4 is a plurality of computers connected to each other via a network such as the Internet.

  The cloud computer 4 acquires report information from the roadside device 3 or another computer (not shown) connected to the Internet. Here, the report information is information indicating to the cloud computer 4 the occurrence of a situation (emergency) required to be notified urgently. Emergency situations are, for example, accidents and natural disasters.

  In one example, the cloud computer 4 acquires disaster information from, for example, a server (not shown) of the Japan Meteorological Agency. Here, the disaster information is information indicating the occurrence of a natural disaster such as an earthquake, tsunami, wildfire, typhoon, tornado, landslide.

  In one example, the cloud computer 4 holds information on the dangerous area and the evacuation destination in the hazard map database 11 as a hazard map when a natural disaster occurs.

  In one example, the cloud computer 4 holds information indicating the position of the roadside machine 3 and information indicating the traveling direction of the road on which the roadside machine 3 is provided in the roadside machine map database 12 as a roadside machine map.

  The cloud computer 4 generates notification information and transmits it to the roadside device 3. Here, the notification information is information that indicates the occurrence of an emergency to the vehicle 2. The notification information is used when the notification unit 7 of the vehicle 2 notifies the people in the vicinity of the occurrence of an emergency.

  The receiving unit 5 receives notification information from the roadside device 3. In one example, the receiving unit 5 is a receiver of an in-vehicle device that is compatible with ETC 2.0 and performs dedicated short range communication (DSRC) with the roadside device 3.

  The control unit 6 controls the notification unit 7 based on the received notification information. In one example, the control unit 6 is a computer that includes a CPU and a ROM, and the CPU reads and executes each program stored in the ROM. In one example, the control unit 6 controls the notification unit 7 based on the received notification information only when the vehicle 2 is stopped.

  Based on the control of the control unit 6, the notification unit 7 notifies the people around the vehicle 2 that the emergency has occurred. In one example, the notification unit 7 is a light emitter provided in the vehicle, such as a headlight, a tail lamp, a hazard lamp, a direction indicator, a room light, and an instrument panel (instrument panel) of the vehicle. In another example, the notification unit 7 is a sounding body provided in the vehicle, such as a vehicle horn.

In one example, the transmission unit 10 transmits accident information to the roadside machine 3. Here, the accident information is information indicating the occurrence of an accident such as a traffic accident or a fire accident.

(First embodiment)
FIG. 2 is a flowchart showing an operation flow of the emergency notification system 1 according to the first embodiment of the present disclosure. This process is realized by, for example, the CPU of the roadside device 3, the cloud computer 4, and the control unit 6 reading and executing programs stored in the ROM.

  In step S1, the control unit 6 of the vehicle 2-1 reporting the accident (report vehicle 2-1) generates accident information. In one example, the reporting vehicle 2-1 includes an accident detection sensor (not shown) such as an airbag, and the reporting vehicle 2-1 is controlled in response to the accident detection sensor of the reporting vehicle 2-1 detecting an accident. Part 6 generates accident information. In another example, when the reporting vehicle 2-1 has a user interface (not shown) such as an emergency button and an accident occurs in the reporting vehicle 2-1 or nearby vehicles 2-2, 2-5, the reporting vehicle 2-1 In response to detecting that the occupant of the vehicle 2-1 has operated the user interface, the control unit 6 of the reporting vehicle 2-1 generates accident information.

  The control unit 6 of the reporting vehicle 2-1 identifies the position where the accident has occurred based on the vehicle position indicated by the information acquired by the position / direction acquisition unit 8. Subsequently, the control part 6 produces | generates the information which shows the specified position as an accident occurrence position, and includes it in accident information. Thereby, the cloud computer 4 can specify the occurrence position of the accident based on the accident information.

  In one example, the control unit 6 generates information indicating the type of accident such as a fire or a collision as information indicating the type of emergency and includes the information in the accident information.

  In step S <b> 2, the transmitter 10 of the reporting vehicle 2-1 that is in the vicinity of the first roadside machine 3-1 or passes through the vicinity of the first roadside machine 3-1 sends the accident information to the first roadside machine 3. -1. In one example, the reporting vehicle 2-1 whose emergency button has been pressed stores accident information until it passes through the vicinity of the first roadside device 3-1, and the reporting vehicle 2-1 includes the first roadside device. When passing the vicinity of 3-1, the transmission part 10 transmits accident information to the 1st roadside machine 3-1.

  In step S3, the first roadside machine 3-1 receives the accident information. In step S <b> 4, the first roadside machine 3-1 transmits accident information to the cloud computer 4. In step S5, the cloud computer 4 receives accident information from the first roadside device 3-1.

  Thus, through step S2 to step S5, the accident information is transferred from the transmitting unit 10 of the reporting vehicle 2-1 to the cloud computer 4.

  In step S <b> 6, the cloud computer 4 identifies an area to be notified of the occurrence of the accident as the notification target area based on the accident occurrence position indicated by the received accident information. In one example, the notification target area is an area included in a predetermined radius (for example, a radius of 1 km) from the accident occurrence position. In another example, the notification target area is an area on a road that can reach an accident occurrence position with a predetermined travel distance (for example, 1 km).

  In step S7, the cloud computer 4 generates notification information. In one example, the cloud computer 4 includes information indicating an accident occurrence position indicated by the received accident information in the notification information. In one example, the cloud computer 4 includes information indicating the type of emergency indicated by the received accident information in the notification information.

  Furthermore, in one example, the cloud computer 4 indicates a direction to be instructed by the notification unit 7 of the vehicles 2-2,..., 2-n (notification vehicles 2-2,..., 2-n) in the notification target area. Information indicating the direction is generated and included in the broadcast information. For example, the cloud computer 4 acquires a roadside machine map from the roadside machine map database 12, and based on the accident occurrence position and the roadside machine map, the direction toward the accident occurrence position on the road where the roadside machine 3 is provided Is generated as the indication direction, and is included in the broadcast information.

  In step S8, the cloud computer 4 transmits notification information to the second roadside machine 3-2 based on the roadside machine map. Here, the 2nd roadside machine 3-2 is all the roadside machines 3 in a notification object area, and is generally a plurality of roadside machines 3.

  In step S <b> 9, the second roadside device 3-2 receives notification information from the cloud computer 4. In step S10, the second roadside machine 3-2 is in the vicinity of the second roadside machine 3-2 or has passed the vicinity of the second roadside machine 3-2. Notification information is transmitted to n (notification vehicles 2-2,..., 2-n). In one example, the second roadside device 3-2 transmits the notification information to the notification vehicles 2-2, ..., 2-n by broadcast communication. In step S11, the receiving unit 5 of the notification vehicles 2-2, ..., 2-n receives notification information from the second roadside device 3-2.

  In this way, the notification information is transferred from the cloud computer 4 to the notification vehicles 2-2,..., 2-n through steps S8 to S11.

  In step S12, the control unit 6 of the notification vehicles 2-2, ..., 2-n causes the notification unit 7 to notify the occurrence of an accident based on the notification information. The contents of the notification will be described later with reference to FIG.

  FIG. 3 is an explanatory diagram of a situation where the occurrence of an emergency is notified in the emergency notification system 1 according to the first embodiment of the present disclosure. In FIG. 3, the number n of the vehicles 2 is described as eight, but the number n may be an arbitrary number.

  As shown in FIG. 3, the vehicle 2-1 has an accident. In this case, the control unit 6 of the vehicle 2-1 generates accident information, and the notification unit 7 of the vehicle 2-1 transmits the accident information to the first roadside machine 3-1. In the example shown in FIG. 3, the vehicle 2-1 is the reporting vehicle 2-1.

  Next, as a result of execution of steps S3 to S11 in the flowchart shown in FIG. 2, the receiving unit 5 of the notification vehicles 2-2,..., 2-8 notifies the cloud computer 4 as shown in FIG. Get information. In addition, as FIG. 3 shows, the 1st roadside machine 3-1 may also function as the 2nd roadside machine 3-2.

  The control unit 6 of the notification vehicles 2-2,..., 2-8 instructs the notification units 7-2,..., 7-8 of the notification vehicles 2-2,. Operate according to an operation pattern indicating a direction. The instruction direction according to the emergency is, for example, the direction in which an accident has occurred. When the notification units 7-2,..., 7-8 are light emitters, the operation pattern is a light emission pattern of the light emitters.

  In one example, as shown in FIG. 3, the headlights of the reporting vehicles 2-2, 2-3, and 2-4 in the same traveling direction D1 as the reporting vehicle 2-1 blink. In one example, the headlights of the reporting vehicles 2-5, 2-6, 2-7, 2-8 in the traveling direction D2 in the lane opposite to the lane in which the reporting vehicle 2-1 is located also blink.

  In one example, the light emission pattern defines the blinking of the light emitter based on the distance d between the accident occurrence position and the vehicle position. Here, the distance may be a straight line distance or a distance along the travel route obtained using the map information acquired from the map information acquisition unit 9.

  For example, the relationship between the distance d and the blinking period of the light emitter is defined by the following binary function F1 that takes values 0 and 1 with respect to the distance d and time t.

  When the value of the binary function F1 is 1, the light emitter is turned on, and when the value of the binary function F1 is 0, the light emitter is turned off. Here, t is time, D and T are arbitrary constants, and m is an arbitrary integer. [X] represents a maximum integer not exceeding x, and Z represents a set of integers. Note that the larger the integer m, the larger the interval between light emission.

  In general, F is an arbitrary periodic function having a real number as a domain and a value of 0 or 1, and D and T are arbitrary constants. Then, the blinking pattern can be defined by the binary function F2 that takes values 0 and 1 with respect to the distance d and time t. When the value of the binary function F2 is 1, the light emitter is turned on, and when the value of the binary function F2 is 0, the light emitter is turned off. Here, the binary function F2 is defined as follows.

  In this way, the people P-1, P-2, and P-3 in the vicinity of the notification vehicles 2-2,..., 2-8 emit light from the illuminant as if the accident occurred at the speed D / T. It looks as if it is flowing toward you. Thereby, people P-1, P-2, P-3 around the notification vehicles 2-2, ..., 2-8 can recognize the direction in which the accident occurred.

  Further, a flying object (not shown) such as a drone equipped with a camera or a helicopter occupant can make a vector so that the light emission of the light emitters of the notification vehicles 2-2,. Can be confirmed from above. As a result, people who are not in the vicinity of the notification vehicles 2-2,..., 2-n (for example, ambulance crews) can easily and quickly confirm the location of the accident, which is a danger source, even at night. Can do.

  In one example, a plurality of binary functions F1 or F2 are determined in advance according to the type of emergency. The control unit 6 of the notification vehicles 2-2,..., 2-n uses a plurality of binary functions F1 or F2 according to the emergency situation type indicated by the notification information. In this way, people P-1, P-2, P-3 in the vicinity of the notification vehicles 2-2, ..., 2-8, or other people can recognize the direction in which the accident occurred. The type of emergency can be determined by checking the light emission pattern.

  When the color of the headlight, tail lamp, hazard lamp, direction indicator, room light, or instrument panel (instrument panel) is variable, by using a function that takes a value indicating the color instead of the above binary function, A light emission pattern may be defined.

  In one example, when the notification unit 7 is a horn, sound is generated in the horn only when the value is 1 in the binary function F1 or F2. In this way, even if people P-1, P-2, and P-3 in the vicinity of the notification vehicles 2-2,. can do.

  In one example, different light emitters emit light depending on the vehicle direction. For example, in the notification vehicles 2-2, 2-3, and 2-4 in which the indication direction D1 coincides with the vehicle direction D1, the headlight blinks. Further, in the notification vehicles 2-5, 2-6, 2-7, and 2-8 in which the indication direction D1 is opposite to the vehicle direction D2, the tail lamps blink.

  Here, in the example, the instruction direction D1 is an instruction direction indicated by the notification information. In another example, the control unit 6 of the notification vehicles 2-2,..., 2-8 acquires an accident occurrence position indicated by the notification information, a vehicle position indicated by information acquired from the position / direction acquisition unit 8, and map information acquisition. Using the map information acquired from the unit 9, the direction from the vehicle position to the accident occurrence position is calculated and determined as the instruction direction D1.

  Thereby, people P-1, P-2, P-3 in the vicinity of the notification vehicles 2-2,..., 2-8 viewing the flashing headlights and tail lamps confirm the directions of the light-emitting bodies that are lit. Thus, the direction in which the accident occurred can be recognized.

This process is realized by, for example, the CPU of the roadside device 3, the cloud computer 4, and the control unit 6 reading and executing programs stored in the ROM.

  In step S21, the cloud computer 4 acquires disaster information from a server (not shown) of the Japan Meteorological Agency. Here, the disaster information is information indicating the occurrence of a natural disaster such as an earthquake, tsunami, wildfire, typhoon, tornado, landslide. In one example, the disaster information includes information indicating a position where the disaster has occurred. In one example, the disaster information includes information indicating the type of disaster. In one example, the disaster information includes information indicating a disaster occurrence position.

  In step S22, the cloud computer 4 identifies the dangerous area. In one example, the cloud computer 4 acquires a hazard map corresponding to the type of disaster from the hazard map database 11, and identifies a dangerous area based on the hazard map and the disaster information.

  In step S <b> 23, the cloud computer 4 identifies an area to be notified of the occurrence of the disaster as the notification target area based on the disaster occurrence position and the disaster type. In one example, the notification target area is an area included within a predetermined radius (for example, a radius of 1 km) from the danger area. In another example, the notification target area is an area included in a specific expressway among areas included in a predetermined radius (for example, a radius of 1 km) from the danger area. In yet another example, the notification target area is an area included in a predetermined distance from the coastline among areas included in a predetermined radius (for example, a radius of 1 km) from the dangerous area.

  In step S24, the cloud computer 4 generates notification information. In one example, the cloud computer 4 generates information indicating a disaster occurrence position based on the acquired disaster information and includes the information in the notification information. In one example, the cloud computer 4 generates information indicating the type of emergency based on the type of disaster and includes the information in the notification information.

  Furthermore, in one example, the cloud computer 4 generates information indicating the direction to be evacuated from a disaster on the road where the roadside device 3 is provided as an instruction direction based on the hazard map and the roadside device map, and includes the information in the notification information . For example, in the case of a tsunami, the direction to evacuate is the direction away from the coastline or the direction away from the river. For example, in the case of a wildfire, the direction to evacuate is the direction away from the wildfire, or in the wildfire windward area, the direction of the wildfire.

  In one example, the cloud computer 4 generates information indicating the direction toward the natural disaster occurrence position as an instruction direction, and includes the information in the notification information.

  Steps S25 to S28 have the same processing contents as steps S8 to S11, respectively, and will not be described.

  In step S29, the control unit 6 of the notification vehicles 2-2,..., 2-n causes the notification unit 7 to notify the occurrence of a natural disaster based on the notification information. The processing content of step S29 is substantially the same except that the processing content of step S12 can use the direction to be evacuated from the disaster as the instruction direction according to the emergency situation.

  That is, the control unit 6 of the notification vehicles 2-2,..., 2-8 determines the direction in which the notification units 7-2,. It is operated according to the operation pattern shown to notify the occurrence of a natural disaster and the direction to evacuate. As a result, people P-1, P-2, P-3 in the vicinity of the notification vehicles 2-2,..., 2-8 can quickly notice the occurrence of a natural disaster and evacuate from the natural disaster. The power direction can be correctly recognized.

  As described above, the emergency notification system 1 according to one aspect of the present disclosure includes the server (cloud computer 4) and the plurality of vehicles 2, and each of the plurality of vehicles 2 is information indicating occurrence of an emergency. Information that includes a control unit 6 that acquires (notification information) from a server and a notification unit 7 that notifies the occurrence of an emergency to the outside of the vehicle, and the control units 6 of the plurality of vehicles 2 indicate the occurrence of an emergency.
