  In addition, the accident notification method according to the present invention is configured such that when the first in-vehicle notification device mounted on the first vehicle detects the occurrence of the accident related to the first vehicle, the vehicle is communicated with another vehicle by inter-vehicle communication. The first vehicle position information is notified, and when the first in-vehicle notification device detects the occurrence of an accident related to the first vehicle, the first vehicle position information is notified to a device outside the vehicle. When the second vehicle-mounted notification device mounted on the second vehicle receives the notification from the first vehicle-mounted notification device through inter-vehicle communication, the position information related to the notification and the position of the second vehicle When it is determined whether the information satisfies a predetermined condition and the second in-vehicle notification device determines that the predetermined condition is satisfied, the position information of the second vehicle and the periphery of the second vehicle are imaged. The image is notified to the device outside the vehicle, and the accident When a device receives a notification from the first vehicle-mounted notification device or the second vehicle-mounted notification device, the device notifies the vehicle of a position within a predetermined range based on the position information related to the notification, When the third in-vehicle notification device mounted on the vehicle receives the notification from the accident notification device, it is determined whether or not the position information related to the notification and the position information of the third vehicle satisfy a predetermined condition. When the third vehicle-mounted notification device determines that the predetermined condition is satisfied, the third vehicle-mounted notification device notifies the accident notification device of position information of the third vehicle and an image obtained by capturing the periphery of the third vehicle. It is characterized by.

In the present invention, the first in-vehicle notification device mounted on the first vehicle notifies the second vehicle of position information by inter-vehicle communication when an accident occurrence is detected, and is provided outside the vehicle. Notify the accident notification device. Here, the first vehicle is a vehicle that has encountered an accident or a vehicle that exists in the vicinity of the location where the accident occurred, and detects the occurrence of an accident based on the detection results of various in-vehicle sensors or images taken by the in-vehicle camera. Can do. Compared with the configuration in which the first in-vehicle notification device notifies the occurrence of an accident to two locations of the second vehicle and the accident notification device outside the vehicle, compared with the configuration in which only one of the notifications is made. It is possible to reliably notify the occurrence of an accident.
When the notification from the first in-vehicle notification device is received by inter-vehicle communication, the second in-vehicle notification device mounted on the second vehicle has a predetermined condition (for example, the Whether the vehicle position information is within a predetermined distance from the notified accident position information). When the predetermined condition is satisfied, the second in-vehicle notification device notifies the accident notification device of an image obtained by imaging the periphery together with the position information. Here, the second vehicle is a vehicle that exists within a range in which inter-vehicle communication with the first vehicle can be performed. When the second vehicle exists in the vicinity of the accident location or travels in the vicinity, the second in-vehicle notification device can notify the accident notification device of a captured image around the accident location.
When an accident notification device provided outside the vehicle receives a notification from the first vehicle or the second vehicle, a predetermined range based on the notified position information (for example, within a few hundred meters or several kilometers from the location where the accident occurred) The position information notified from the first vehicle or the second vehicle is notified to the third vehicle existing in the range of the inside or the like. Note that the predetermined range notified by the accident notification device is a range wider than the range of inter-vehicle communication by the first vehicle and the second vehicle, and the third vehicle may include the second vehicle.
When receiving a notification from the accident notification device, the third in-vehicle notification device mounted on the third vehicle determines whether the notified position information and its own position information satisfy a predetermined condition. The predetermined condition determined by the third vehicle may be the same condition as the predetermined condition determined by the second vehicle, or may be a different condition. When the predetermined condition is satisfied, the third in-vehicle notification device notifies the accident notification device of an image obtained by imaging the periphery together with the position information. Thereby, when the 3rd vehicle which exists in the range which cannot perform vehicle-to-vehicle communication with the 1st vehicle runs in the neighborhood of an accident occurrence place, the 3rd in-vehicle notification device is a picked-up image around an accident occurrence place. Can be notified to the accident notification device.

  In the present invention, the third in-vehicle notification device mounted on the third vehicle continuously determines whether the position information satisfies the predetermined condition after receiving the notification from the accident notification device, When it is determined that the predetermined condition is satisfied, a captured image is acquired and notified to the accident notification device. As a result, when the notification from the accident notification device is received, even if the third vehicle does not exist in the vicinity of the accident occurrence location, the third vehicle approaches the accident occurrence location by subsequent driving. In such a case, the third in-vehicle notification device can acquire and notify an image.

  Moreover, in this invention, an accident notification apparatus memorize | stores the image notified from the 2nd vehicle-mounted notification apparatus and the 3rd vehicle-mounted notification apparatus. The accident notification device determines, for example, whether further image acquisition is necessary based on the stored image. For example, when the accident vehicle is removed from the accident site, the accident notification device can determine that the accident processing is completed and further image acquisition is unnecessary. When it is determined that image acquisition is not necessary, the accident notification device requests the third in-vehicle notification device to stop image acquisition. Thereby, it is possible to stop the processing for the third in-vehicle notification device that continuously performs processing such as position determination in accordance with the notification from the accident notification device, and to continue to notify the accident notification device of unnecessary images. Can be prevented.

  In the accident notification system according to the present invention, the accident notification device outside the vehicle receives the notification from the first in-vehicle notification device that detects the occurrence of the accident or the second in-vehicle notification device that receives the notification from the first in-vehicle notification device. Then, the accident notification device notifies the third in-vehicle notification device mounted on the third vehicle within the predetermined range based on the notified position information, and the third in-vehicle notification device receives its position information in response to this notification. When the predetermined condition is satisfied, a surrounding captured image is notified to the accident notification device. Thereby, it is possible to cause the third vehicle existing in a wider range to acquire information related to the accident, and to notify the information related to the accident or the disaster over a long period of time.

  1-3 is a schematic diagram for demonstrating the outline | summary of the accident notification system which concerns on this Embodiment. In the accident notification system according to the present embodiment, an in-vehicle notification device 10 (see FIG. 4) mounted on a plurality of vehicles 1 and a server device 4 installed in a management center, for example, are connected to the base of a mobile phone communication network. It is the structure which notifies the information regarding an accident between the vehicle 1 and the server apparatus 4 by performing communication via the station 6. In the accident notification system according to the present embodiment, each vehicle 1 is equipped with a function of performing wireless communication with other vehicles, that is, a so-called inter-vehicle communication function. It can be carried out.

  Note that the accident notification system according to the present embodiment includes a plurality of vehicles 1, but when it is necessary to distinguish between them, alphabets a, b... At the end of the reference numerals, such as vehicles 1a, 1b. To distinguish. Similarly, a plurality of base stations 6 are distinguished as 6a and 6b when it is necessary to distinguish them. In addition, the example illustrated in FIGS. 1 to 3 schematically illustrates a state of notification performed between the plurality of vehicles 1 and the server device 4 when two vehicles 1a and 1b cause a collision accident on the road. The change of the road condition and the vehicle position is shown in time series in the order of FIG. 1, FIG. 2 and FIG.

  For example, it is assumed that an accident occurs in which the vehicle 1b collides with the opposite vehicle 1a across the center line on the road. In this case, the vehicle 1b (the in-vehicle notification device 10 mounted on the vehicle 1b) detects the occurrence of an accident using various sensors or the like (see FIG. 1A). The vehicle 1b that detected the accident communicates with the server device 4 via the nearest base station 6a by wireless communication using the mobile phone communication network, and notifies the occurrence of the accident (see FIG. 1B). . At this time, the vehicle 1b notifies the server device 4 of its own position information based on GPS (Global Positioning System). Hereinafter, the notification performed by the vehicle 1 that has detected an accident is referred to as an accident occurrence notification, and the position information notified at this time is referred to as an accident occurrence position information. In addition, the vehicle 1b notifies the surrounding vehicles 1c and 1d of the occurrence of an accident by wireless communication using the inter-vehicle communication function (see FIG. 1C). Also at this time, the vehicle 1b notifies the other vehicles 1c and 1d of its own position information as accident occurrence position information. In addition, although the process of accident detection, an accident occurrence notification, etc. can be performed similarly about the vehicle 1a, description is abbreviate | omitted in this example.

  The vehicles 1c and 1d that have received the accident occurrence notification by the inter-vehicle communication from the vehicle 1b compare the notified accident occurrence position information with the position information of the own vehicle acquired based on the GPS. When the position of the own vehicle is within a predetermined range (for example, within a few meters to a few tens of meters) from the accident occurrence position, the vehicles 1c and 1d take an image of the surroundings with a vehicle-mounted camera. In addition, when it is not within the predetermined range from the accident occurrence position, the vehicles 1c and 1d do not perform imaging by the in-vehicle camera at this time, continuously compare the positional information, and then continue to travel to the predetermined range from the accident occurrence position. When moving to the camera, the camera will take a picture. When imaging is performed with an in-vehicle camera, the vehicle 1c and the vehicle 1d are able to obtain an image obtained by imaging and position information of the own vehicle at the time of shooting by using wireless communication using a mobile phone communication network. The server apparatus 4 is notified via the base station 6a (see (D) of FIG. 1). Hereinafter, the notification performed by the vehicle 1 in response to the accident occurrence notification is referred to as an accident situation notification. Note that the imaging by the vehicles 1c and 1d and the accident status notification may be repeatedly performed while the vehicles 1c and 1d are within a predetermined range from the accident occurrence position.

  The server device 4 that has received the accident occurrence notification from the vehicle 1b stores the notified accident occurrence position information. Moreover, the server apparatus 4 acquires and manages the traveling position of each vehicle 1 periodically, and searches for the vehicle 1 traveling within a predetermined range (for example, within several hundred meters to several kilometers) from the accident occurrence position. To do. The server device 4 notifies the corresponding vehicles 1e and 1f of the occurrence of an accident via the base station 6b by wireless communication using a mobile phone communication network (see (E) of FIG. 1). At this time, the server apparatus 4 notifies the vehicles 1e and 1f of the accident occurrence position information notified from the vehicle 1b. Hereinafter, the notification performed by the server device 4 is also referred to as an accident occurrence notification. The accident occurrence notification by the server device 4 can also be made to the vehicles 1a to 1d, but the description is omitted in this example. Note that the vehicle 1b may not be able to transmit an accident occurrence notification to the server device 4 due to a failure of the device associated with the accident, but the server device 4 receives an accident status notification from another vehicle 1c or 1d. May be configured to transmit accident occurrence notifications to the vehicles 1e and 1f even when no accident occurrence notification is received from the vehicle 1b. In this case, the server device 4 can handle, for example, the position information notified by the accident situation notification received first as the accident occurrence position information.

  The vehicles 1e and 1f that have received the accident occurrence notification from the server device 4 capture the surroundings with the in-vehicle camera when the position of the own vehicle is within a predetermined range (for example, within several meters to several tens of meters) from the accident occurrence position. . The conditions for performing imaging by the in-vehicle camera when the accident occurrence notification is received from the server device 4 may be the same as or different from the conditions when the accident occurrence notification is received from the vehicle 1b. If it is not within the predetermined range from the accident occurrence position, the vehicles 1e and 1f do not perform imaging by the in-vehicle camera at this time, and continuously compare the position information, and within the predetermined range from the accident occurrence position by the subsequent running When moving to the camera, take an image with the in-vehicle camera. When imaging is performed with an in-vehicle camera, the vehicle 1e and the vehicle 1f can obtain the nearest image by radio communication using a mobile phone communication network, with the image obtained by imaging and the position information of the own vehicle when the imaging is performed. The server apparatus 4 is notified through the base station 6a (see (F) in FIG. 2). The imaging and accident status notification by the vehicles 1e and 1f may be repeatedly performed while the vehicles 1e and 1f are within a predetermined range from the accident occurrence position.

  The server device 4 that has received the accident situation notification from the vehicles 1c to 1f stores the captured image of the in-vehicle camera included in the accident situation notification and the positional information at the time of imaging in association with each other. The server device 4 may store the date / time information when the notification is further received or the identification information of the vehicle 1 that transmitted the notification in association with these pieces of information. The server device 4 determines whether or not further acquisition of images related to the accidents of the vehicles 1a and 1b is necessary. At this time, the server device 4 may determine whether or not the accident processing has ended based on, for example, the image received as the accident status notification, and based on a report from an emergency worker who has performed the accident processing, for example. It may be determined whether or not it is necessary to acquire an image by a method other than these methods.

  When it is determined that image acquisition is necessary, the server device 4 continuously notifies the vehicle 1 of the occurrence of an accident. In the illustrated example, the server device 4 further notifies the occurrence of an accident to the vehicle 1g (see (G) in FIG. 2). In response to the accident occurrence notification from the server device 4, the vehicle 1 g performs imaging with the in-vehicle camera when traveling within a predetermined range from the accident occurrence position, and notifies the server device 4 of the accident situation ((FIG. 3 ( H)). In this example, the server device 4 that has received the notification of the accident situation made by the vehicle 1g determines that the accident processing has ended based on the notified image and determines that it is not necessary to acquire a further image. To do.

  When it is determined that image acquisition is not necessary, the server device 4 transmits a request for stopping the accident status notification to the vehicle 1 (see (I) in FIG. 3). At this time, for example, the server device 4 may transmit a stop request to the vehicle 1 existing within a predetermined range from the accident occurrence position (a range that is the same as or wider than the range in which the accident occurrence notification is transmitted). Further, for example, a stop request may be transmitted to the vehicle 1 that has transmitted the accident occurrence notification so far, or a stop request may be transmitted to the vehicle 1 selected based on a criterion other than these. In this example, the server device 4 transmits a stop request to the vehicle 1h existing within the same range as the transmission range of the accident occurrence notification. The vehicle 1 that has received the stop request from the server device 4 stops processing such as comparison between the accident occurrence position and its own travel position, imaging of the surroundings by the in-vehicle camera, and notification of the captured image.

  As described above, in the accident notification system according to the present embodiment, the server device 4 collects images over a long period from the occurrence of an accident in the vehicles 1a and 1b to the end of the accident process. Thereby, for example, when a secondary disaster occurs at an accident site, it is possible to perform processing such as analyzing the cause of the secondary disaster based on the image accumulated by the server device 4.

  In the accident notification system according to the present embodiment having the above-described configuration, when the accident detection unit 32 detects the occurrence of an accident, the in-vehicle notification device 10 mounted on the first vehicle 1b is connected to the inter-vehicle communication device 11. The accident occurrence notification including the accident occurrence position information is transmitted to the second vehicles 1c and 1d, and the accident occurrence notification is transmitted to the server device 4 provided outside the vehicle 1. The vehicle-mounted notification device 10 can detect the occurrence of an accident based on the detection result of the vehicle-mounted sensor 13 or the captured image of the vehicle-mounted camera 14. The in-vehicle notification device 10 of the first vehicle 1b transmits the accident occurrence notification to the two locations of the second vehicle 1c, 1d and the server device 4 outside the vehicle 1, so that only one of them is notified. The occurrence of an accident can be more reliably notified as compared with the configuration for performing the above.

  The in-vehicle notification device 10 mounted on the second vehicle 1c, 1d, when the accident occurrence notification from the first vehicle 1b is received by the inter-vehicle communication device 11, It is determined whether or not the vehicle position information satisfies a predetermined condition (for example, the position of the host vehicle is within a predetermined range from the accident occurrence position). When the predetermined condition is satisfied, the in-vehicle notification device 10 transmits an image obtained by imaging by the in-vehicle camera 14 to the server device 4 as an accident status notification together with the position information of the own vehicle. Thereby, when the second vehicles 1c and 1d exist in the vicinity of the accident occurrence location or when traveling near the accident occurrence location, the in-vehicle notification device 10 can notify the server device 4 of the captured image around the accident occurrence location. .

  When the server device 4 provided outside the vehicle 1 receives the accident occurrence notification from the first vehicle 1b or the accident situation notification from the second vehicles 1c and 1d, the server device 4 is predetermined based on the notified accident occurrence position information. Accident occurrence notification is sent to the third vehicles 1e and 1f existing within the range. The transmission range of the accident occurrence notification by the server device 4 is preferably wider than the transmission range of the accident occurrence notification by the inter-vehicle communication of the first vehicle 1b. Further, the third vehicle 1 to which the server device 4 transmits the accident occurrence notification may include the second vehicle 1.

  When the in-vehicle notification device 10 mounted on the third vehicles 1e and 1f receives an accident occurrence notification from the server device 4, the notified accident occurrence position information and the position information of the host vehicle satisfy predetermined conditions. It is determined whether or not it is satisfied. Note that the third vehicle 1e, 1b is determined according to an accident occurrence notification from the server device 4, and the second vehicle 1c, 1d is determined according to an accident occurrence notification from the first vehicle 1b. The conditions may be the same conditions or different conditions. When the predetermined condition is satisfied, the in-vehicle notification device 10 transmits an image obtained by imaging by the in-vehicle camera 14 to the server device 4 as an accident status notification together with the position information of the own vehicle. Thereby, when the third vehicles 1e and 1f exist in the vicinity of the accident occurrence location or when traveling in the vicinity, the in-vehicle notification device 10 can notify the server device 4 of the captured image around the accident occurrence location. .

  With these configurations, the accident notification system according to the present embodiment can cause the vehicle 1 existing in a wider range to acquire information related to the accident, and can transmit information related to the accident or disaster over a long period of time. You can be notified.

  In addition, when the in-vehicle notification device 10 receives an accident occurrence notification from another vehicle 1 through inter-vehicle communication and receives an accident occurrence notification from the server device 4, the accident occurrence position information and the position information of the host vehicle are obtained. Whether or not the predetermined condition is satisfied is continuously determined. When it is determined that the predetermined condition is satisfied, the captured image of the in-vehicle camera 14 is acquired and the accident status notification is transmitted to the server device 4. Thus, when the accident occurrence notification is received, even if the vehicle 1 does not exist in the vicinity of the accident occurrence location, the vehicle-mounted notification device is used when the vehicle 1 approaches the accident occurrence location due to subsequent travel. 10 can acquire a captured image and transmit an accident status notification.

  The server device 4 stores the image notified from the in-vehicle notification device 10 of the vehicle 1 in the accident image DB 56 of the storage unit 41. For example, the server device 4 determines whether or not further image acquisition is necessary based on the image received and stored from the vehicle 1. For example, when the accident vehicles 1a and 1b are removed from the accident site, the server device 4 can determine that the accident processing is completed and further image acquisition is unnecessary. When it is determined that image acquisition is not necessary, the server device 4 transmits a stop request to the vehicle 1. Accordingly, the processing can be stopped for the in-vehicle notification device 10 that continuously performs processing such as position determination in response to the accident occurrence notification from the server device 4, and unnecessary images are continuously notified to the server device 4. Can be prevented.

  In the present embodiment, the notification regarding the accident of the vehicle 1 is transmitted and received. However, the present invention is not limited to this. For example, a notification regarding a phenomenon other than an accident such as a disaster may be transmitted and received. In addition, the vehicle 1 that has received the accident occurrence notification transmits the captured image of the in-vehicle camera 14 to the server device 4 as the accident situation notification. However, the present invention is not limited to this, and the vehicle 1 is information other than the image, such as an accident occurrence. Various information such as voice information, temperature information, and weather information around the location may be acquired by the in-vehicle sensor and transmitted to the server device 4. Also about the 1st vehicle 1b which detected accident occurrence, it is good also as a structure which transmits information, such as a captured image of the vehicle-mounted camera 14, to the server apparatus 4. FIG.

  The in-vehicle notification device 10 that has received the accident occurrence notification captures the in-vehicle camera 14 and transmits the image to the server device 4 when the position of the host vehicle is within a predetermined range from the accident occurrence position. The condition for performing is not limited to a predetermined range from the accident occurrence position. For example, when map information can be handled in cooperation with a car navigation device or the like, the in-vehicle notification device 10 may further determine that the vehicle is traveling on the same road as the road where the accident occurred.

  In addition, the server device 4 is configured to transmit the accident occurrence notification to the vehicle 1 existing within a predetermined range from the accident occurrence position. However, the selection condition of the vehicle 1 that is the transmission destination of the accident occurrence notification by the server device 4 is the same. Not exclusively. For example, the server device 4 may be configured to predict the travel route of each vehicle 1 and transmit the accident occurrence notification only to the vehicle 1 that is expected to travel around the accident occurrence position.

  Moreover, although the vehicle-mounted notification apparatus 10 was set as the structure which detects generation | occurrence | production of an accident based on the detection result of the vehicle-mounted sensor 13, and / or the captured image of the vehicle-mounted camera 14, it does not restrict to this. Any method for detecting an accident by the in-vehicle notification device 10 may be used. For example, an accident notification switch or the like may be provided in the vicinity of the driver's seat of the vehicle 1 to detect the occurrence of an accident according to the switch operation by the driver.

  The in-vehicle camera 14 may be configured to always capture an image and store the image in a memory or the like instead of performing an image according to a command from the in-vehicle notification device 10 when necessary. The in-vehicle notification device 10 may acquire necessary ones from the images captured by the in-vehicle camera 14 and transmit them to the server device 4. Further, in this case, for example, for the first vehicle 1b that has detected the accident and the second vehicles 1c and 1d that have received the notification of the occurrence of the accident through inter-vehicle communication, an image before the occurrence of the accident is transmitted to the server device 4. Also good.
