Japanese Unexamined Patent Application Publication No. 2008-021030

For example, when an abnormality such as a disaster occurs, a vehicle occupant may get off the vehicle and evacuate on foot. At this time, it is difficult for the driver of the other vehicle to immediately grasp the evacuation situation of the occupants of the vehicle, so the driver may not be able to drive the other vehicle appropriately. This point is not taken into consideration in the technique described in Patent Document 1.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is capable of providing information to other vehicles existing in the vicinity of one's own vehicle, thereby improving safety when an abnormality occurs. An object of the present invention is to provide a notification device.

An abnormality notification device according to one aspect of the present invention is an abnormality notification device that guides an occupant of a vehicle to an evacuation route when an abnormality occurs inside the vehicle or in the vicinity of the vehicle. and presenting means for presenting the recommended behavior calculated based on the evacuation route to other vehicles in the vicinity of the own vehicle when the abnormal situation occurs.

1 is a block diagram showing the configuration of an anomaly notification device according to an embodiment; FIG. It is a figure which shows an example of the scene where the abnormality alerting|reporting apparatus which concerns on embodiment operate|moves. It is a flow chart which shows operation of an anomaly alarm device concerning an embodiment. It is a flowchart which shows operation|movement of the abnormality notification apparatus which concerns on the modification of embodiment.

An embodiment of an abnormality notification device will be described with reference to FIGS. 1 to 3. FIG. In FIG. 1 , an abnormality notification device 10 is mounted on a vehicle 1 . The anomaly notification device 10 includes a danger detection device 11 and a danger notification device 12 .

The danger detection device 11 detects the vehicle 1 based on, for example, an image captured by an onboard camera (not shown) of the vehicle 1, outputs of various sensors such as an acceleration sensor and a speed sensor mounted on the vehicle 1, and the like. It is configured to determine whether an abnormal situation has occurred in at least one of the inside and the periphery of the. As for the method of determining whether or not an abnormal situation has occurred, various existing aspects can be applied, so detailed description thereof will be omitted.

When the danger sensing device 11 determines that an abnormal situation has occurred in at least one of the inside and the surroundings of the vehicle 1, the danger notification device 12 detects the presence of the occupants of the vehicle 1 and other vehicles in the vicinity of the vehicle 1 (for example, in FIG. 1, vehicles 2 and 3) are configured to notify predetermined information.

Predetermined information to be notified to the occupants of the vehicle 1 from the danger notification device 12 includes, for example, evacuation route information indicating an evacuation route. If it is difficult for the occupants to stay inside the vehicle 1 or to move the vehicle 1 due to the occurrence of an abnormal situation, the evacuation route information is information indicating an evacuation route for the occupants to evacuate on foot. can be On the other hand, if an abnormal situation has occurred but the vehicle 1 can be safely moved, the evacuation route information is information indicating an evacuation route for the occupants to use the vehicle 1 to evacuate. good.

Here, the danger notification device 12 receives information (for example, image of the road to be monitored, etc.) can be received. The information acquired by the road monitoring device 20 may be sequentially accumulated in the server 30 . The danger notification device 12 identifies a place where the occupants of the vehicle 1 can evacuate from, for example, the positional information of the vehicle 1, the map information, the information acquired by the road monitoring device 20, and the like. The evacuation route information may be generated by calculating an evacuation route to the place where the evacuation route is located.

The predetermined information notified from the danger notification device 12 to the other vehicle includes, for example, information for calling the attention of the driver of the other vehicle, information for guiding the other vehicle, and the like. "Information for guiding other vehicles" may be information indicating recommended behavior of other vehicles. Here, the "recommended behavior of other vehicles" means, for example, behavior that allows other vehicles to avoid the current abnormal situation, behavior that other vehicles should take to prevent the current abnormal situation from expanding, and the like. can be

The danger notification device 12 may calculate the recommended behavior from, for example, the location information of the vehicle 1, the map information, the information acquired by the road monitoring device 20, the evacuation route indicated by the evacuation route information, and the like. At this time, the danger notification device 12 may calculate the recommended behavior so that the evacuation route indicated by the evacuation route information does not intersect with the course of another vehicle when the recommended behavior is taken.

The danger notification device 12 displays predetermined information such as evacuation route information on, for example, a display device (for example, a display of a car navigation device) provided in the passenger compartment of the vehicle 1 or a display screen of a mobile terminal possessed by a passenger of the vehicle 1. , the occupant of the vehicle 1 may be notified of predetermined information. In addition, the danger notification device 12 displays predetermined information such as recommended behavior of other vehicles on a display device such as an electronic bulletin board whose display surface faces the outside of the vehicle 1, so that other vehicles can receive predetermined information. information may be notified.

The operation of the abnormality notification device 10 will be specifically described with reference to FIG. FIG. 2 shows an example of a scene in which the vehicle 1 rear-ends another vehicle. At this time, the danger detection device 11 of the abnormality notification device 10 determines that an abnormal situation has occurred, for example, based on the acceleration detected by the acceleration sensor of the vehicle 1 at the time of the rear-end collision.

The danger notification device 12 of the abnormality notification device 10 determines, for example, the area A in FIG. Identify as location. Then, the danger notification device 12 calculates an evacuation route from the left side of the vehicle 1 toward the area A, for example. The danger notification device 12 notifies the occupants of the vehicle 1 of evacuation route information indicating the calculated evacuation route.

The danger notification device 12 calculates the recommended behavior of other vehicles based on, for example, the location information of the vehicle 1, the map information, the information acquired by the road monitoring device 20, the evacuation route indicated by the evacuation route information, and the like. Here, as a recommended behavior of another vehicle, a lane change to a lane on the right side of the lane in which the vehicle 1 is present will be taken. The danger notification device 12 notifies the other vehicles 2 and 3 approaching the vehicle 1 from behind the vehicle 1 of the calculated recommended behavior. Due to the operation of this danger notification device 12, in the example shown in FIG. An arrow and are displayed. In addition to the visual information, the danger notification device 12 may emit audio information such as a warning sound.

Next, the operation of the abnormality notification device 10 will be described with reference to the flowchart of FIG. In FIG. 3, when the danger detection device 11 of the abnormality notification device 10 determines that an abnormality has occurred in at least one of the inside and the periphery of the vehicle 1 (step S101), the abnormality notification device 10 performs self-diagnosis and Vehicle state determination is performed (step S102). Since various existing aspects can be applied to the self-diagnosis and vehicle state determination, detailed description thereof will be omitted.

After the process of step S102, the danger notification device 12 of the abnormality notification device 10 sends to the server 30 information indicating the surrounding situation of the vehicle 1 acquired by the road monitoring device 20 that monitors the road on which the vehicle 1 is present. request (step S103). Then, the danger notification device 12 calculates predetermined information to be notified to the occupants of the vehicle 1 and other vehicles around the vehicle 1 . After that, the danger notification device 12 notifies the occupants of the vehicle 1 of the evacuation route information, thereby guiding the occupants to evacuate, and notifies other vehicles of predetermined information such as recommended behavior. The evacuation situation is presented to other vehicles (step S104).

Even after a sufficient period of time (for example, a period of time during which the occupants of the vehicle 1 can evacuate with sufficient time, etc.) has passed since the process of step S104 was started, the danger notification device 12 does not notify other vehicles of the recommended behavior. By continuing notification of predetermined information such as the above, other vehicles are alerted (step S105).

(technical effect)
For example, in an automatic driving vehicle without a crew such as a driver, when an abnormality such as an accident occurs while passengers are present, it is necessary to evacuate the passengers appropriately. In this case, information such as an evacuation route is often notified to passengers by the function of the automatically driven vehicle (function corresponding to the abnormality notification device 10 described above). On the other hand, it is often the case that the alerting of other vehicles in the vicinity of the automated driving vehicle is insufficient. This could endanger the safety of passengers who exit self-driving vehicles to evacuate. In addition, as the above-mentioned automatic driving vehicle, for example, a bus-type automatic driving vehicle is exemplified.

On the other hand, in the abnormality notification device 10, the danger notification device 12 notifies other vehicles around the vehicle 1 of predetermined information such as recommended behavior. Therefore, according to the abnormality notification device 10 , in addition to guiding the occupants of the vehicle 1 to evacuate, it is also possible to guide other vehicles around the vehicle 1 . As a result, it is possible to safely evacuate the occupants who have exited the vehicle 1 in order to evacuate. Thus, according to the abnormality notification device 10, it is possible to provide information to other vehicles existing in the vicinity of the vehicle 1, thereby improving safety in the event of an abnormality.

<Modification>
A modification of the abnormality notification device 10 described above will be described with reference to the flowchart of FIG. In FIG. 4, after the process of step S103, the danger notification device 12 of the abnormality notification device 10 determines that the information acquired from the server 30 (that is, the information indicating the surrounding situation of the vehicle 1 acquired by the road monitoring device 20) is valid. (step S201). Here, for example, when the error in the information obtained from the server 30 is within an allowable range, or when the time indicated by the time information attached to the information obtained from the server 30 is different from the current time. It may be determined that the information acquired from the server 30 is valid, such as when it is within a predetermined range.

In the process of step S201, when it is determined that the information acquired from the server 30 is valid (step S201: Yes), the process of step S204, which will be described later, is performed. On the other hand, in the process of step S201, when it is determined that the information acquired from the server 30 is not valid (step S201: No), the danger notification device 12 uses a sensor acquired by a camera or the like mounted on the vehicle 1. The surrounding situation of the vehicle 1 is determined from the information (step S202). This is because the information indicating the surrounding conditions of the vehicle 1 acquired by the road monitoring device 20 cannot be used.

After the process of step S202, the danger notification device 12 determines whether or not the sensor information used in the process of step S202 is valid (step S203). Here, the danger notification device 12 may determine that the sensor information is valid, for example, when the error of the sensor information is within the allowable range.

In the process of step S203, when it determines with sensor information not being effective (step S203: No), the operation|movement shown in FIG. 4 is complete|finished. This is because neither the information indicating the surrounding conditions of the vehicle 1 acquired by the road monitoring device 20 nor the sensor information can be used. After that, after a predetermined period of time has elapsed, the processes after step S101 may be performed again.

In the process of step S203, if it is determined that the sensor information is valid (step S203: Yes), the danger notification device 12 determines the danger around the vehicle 1 based on the information acquired from the server 30 or the sensor information. and calculates an evacuation route and the like for evacuating the occupants of the vehicle 1 (step S204). Thereafter, the danger notification device 12 notifies the occupants of the vehicle 1 of the evacuation route information, thereby guiding the occupants to evacuate (step S205), and notifies other vehicles of predetermined information such as recommended behavior. By doing so, the other vehicle is alerted (step S206).
