As described above, the processing circuit 200b in the server device 200 can realize the above-described functions by hardware, software, firmware, or a combination thereof.

Next, the operation of the collision notification system will be described.
FIG. 5 is a sequence diagram showing the operation of the collision notification system according to the first embodiment.
When the collision detection information of the host vehicle is input from the vehicle information acquisition unit 101 (step ST1), the control unit 102 of the in-vehicle device 100 further detects a collision of the host vehicle from the information input from the vehicle information acquisition unit 101. The captured image around the host vehicle at the time when the host vehicle is detected, the time information when the collision of the host vehicle is detected, the position information of the host vehicle, and the type information of the host vehicle are acquired (step ST2). The control unit 102 generates collision data from the captured image, time information, position information, and own vehicle type information acquired in step ST2, and stores the collision data in the collision data storage unit 103 (step ST3). Moreover, the control part 102 transmits the collision data produced | generated by step ST3 to the server apparatus 200 via the vehicle-mounted side communication part 104 (step ST4).

  The process part 202 of the server apparatus 200 receives the collision data transmitted from the vehicle-mounted apparatus 100 via the server side communication part 201 (step ST5). The processing unit 202 selects a plurality of candidates for the management apparatus 300 that requests a collision accident process from the position information described in the received collision data and the position information of each management apparatus 300 stored in the management apparatus database 203. (Step ST6). The process part 202 transmits the positional information on the location where the collision has occurred to the plurality of management devices 300 selected in step ST6 as simple information (step ST7).

  The plurality of management devices 300 receive the simple information (step ST8). In each management device 300 that has received the simple information, it is determined whether or not the accident handling of the collision occurring at the point indicated by the simple information is possible, and the management device 300 that has judged that the collision handling of the collision is possible. Transmits a response to server apparatus 200 (step ST9). When the processing unit 202 of the server apparatus 200 receives the response transmitted in step ST9 via the server side communication unit 201 (step ST10), the server side communication unit 201 uses the captured image when the collision occurs as detailed information. Is transmitted to the management apparatus 300 that has responded, and information indicating the transmission is stored in the response information storage unit 204 (step ST11). When the management apparatus 300 responding at step ST9 receives the detailed information (step ST12), the management apparatus 300 confirms the received detailed information and determines whether it is possible to finally handle the collision accident. If it is determined that it is possible, a response is transmitted to the server device 200 (step ST13).

  When receiving the response transmitted in step ST13, the processing unit 202 of the server device 200 determines a management device 300 that requests a collision accident process from the management devices 300 that have responded (step ST14). In step ST14, when there is a response from a plurality of management devices 300, the processing unit 202 determines to request the management device 300 located closest to the point where the collision has occurred for the collision accident processing. The process part 202 transmits a notification of determination with respect to the management apparatus 300 determined by step ST14 (step ST15). The management apparatus 300 that has received the notification of determination transmitted in step ST15 executes an accident process (step ST16) and ends the process. With the above processing, the collision notification system can determine the management device 300 that performs the accident processing, and the determined management device 300 can execute the accident processing of the collision.

Next, a process for monitoring the traveling of the vehicle will be described with reference to the flowchart of FIG. In addition, the process which monitors driving | running | working of a vehicle shall be performed in the vehicle-mounted apparatus 100, after transmission of the collision data of step ST4 in the sequence diagram of FIG.
FIG. 6 is a flowchart showing the operation of the in-vehicle device 100 of the collision notification system according to the first embodiment.
When the collision data transmission process of step ST4 in the sequence diagram shown in FIG. 5 is performed by the control unit 102 of the in-vehicle device 100, the travel monitoring unit 105 displays the position information of the host vehicle acquired by the vehicle information acquisition unit 101. It is determined whether or not the vehicle continues to travel after the collision (step ST21). If the host vehicle does not continue running, that is, if the host vehicle is stopped (step ST21; NO), the process proceeds to step ST26 described later.

  On the other hand, when the host vehicle continues to travel (step ST21; YES), the travel monitoring unit 105 further refers to the position information of the host vehicle and sets the travel distance of the host vehicle from the point where the collision has occurred in advance. It is determined whether or not the threshold value is exceeded (step ST22). When the travel distance does not exceed the preset distance (step ST22; NO), the travel monitoring unit 105 outputs the determination results of step ST21 and step ST22 to the control unit 102. Based on the determination result input from the travel monitoring unit 105, the control unit 102 performs control to output information that prompts the occupant to stop traveling to the output device 404 (step ST23). Thereafter, the flow returns to step ST21 and repeats the above-described processing.

  On the other hand, when the travel distance exceeds the preset distance (step ST22; YES), the travel monitoring unit 105 outputs the determination results of step ST21 and step ST22 to the control unit 102. Based on the determination result input from the travel monitoring unit 105, the control unit 102 outputs control information for stopping the vehicle to the operation control device 405, and outputs information for notifying the output device 404 that the vehicle should be stopped urgently. (Step ST24). Here, the control information for stopping the vehicle is information for causing the operation control device 405 to execute a process of, for example, relaxing the accelerator of the vehicle and applying a brake.

  The traveling monitoring unit 105 refers to the position information of the host vehicle acquired by the vehicle information acquiring unit 101 and determines whether the host vehicle has stopped (step ST25). The determination process in step ST25 may be determined by the travel monitoring unit 105 monitoring the control state of the operation control device 405. When the host vehicle is not stopped (step ST25; NO), the process returns to step ST24 and the control for stopping the vehicle is continued. On the other hand, when the host vehicle stops (step ST25; YES), the traveling monitoring unit 105 outputs the determination result of step ST25 to the control unit 102. Based on the determination result input from the travel monitoring unit 105, the control unit 102 controls the operation control device 405 to execute the lock process (step ST26), and ends the process. Here, the lock process is a process for disabling the travel of the vehicle, for example, a process for stopping the engine of the vehicle so that the vehicle cannot be started.

In the process of step ST22 described above, the threshold used by the traveling monitoring unit 105 to determine whether the traveling distance exceeds a preset distance is arbitrarily set based on the distance at which the vehicle can safely stop. It can be set.
In addition, in the processing of step ST23 described above, as the output of information that prompts the occupant to stop traveling, for example, a message that strongly urges the vehicle to stop is output, the message is output on both the display and the speaker, or the For example, the message may be output with the output volume increased.
Moreover, in the process of step ST24 mentioned above, as an output of the information which notifies an occupant to stop a vehicle urgently, for example, the message which notifies the emergency stop of a vehicle blinks on a display, and the said message is displayed with a warning sound. As an example, voice output from a speaker can be cited.

  In step ST21 and step ST22 described above, the travel monitoring unit 105 refers to the position information of the host vehicle input from the vehicle information acquisition unit 101, and determines whether or not the host vehicle continues to travel after the collision. Although the case where it is determined whether or not the traveling distance of the host vehicle from the point where the collision has occurred is equal to or greater than a preset threshold value, the traveling monitoring unit 105 acquires the driving control information from the driving control device 405. The traveling of the host vehicle and the traveling distance of the host vehicle may be determined.

Next, processing for confirming the response status of the management device 300 in the in-vehicle device 100 will be described with reference to the sequence diagram of FIG. In the in-vehicle device 100, the processing for confirming the response status of the management device 300 is performed after the lock processing for disabling the vehicle in the flowchart shown in FIG. 6 is performed and in the sequence diagram shown in FIG. This is executed after the simple information transmission process of step ST7.
FIG. 7 is a sequence diagram illustrating a response status confirmation operation of the management device 300 in the in-vehicle device 100 of the collision notification system according to the first embodiment.

The control unit 102 transmits an inquiry as to whether or not the detailed information has been transmitted to the management device 300 to the server device 200 via the in-vehicle communication unit 104 (step ST31). When the processing unit 202 of the server device 200 receives an inquiry via the server-side communication unit 201 (step ST32), the processing unit 202 sends detailed information to the management device 300 that has responded to the simple information stored in the response information storage unit 204. Information indicating whether it has been transmitted is acquired (step ST33). The process part 202 transmits the information acquired by step ST33 to the vehicle-mounted apparatus 100 via the server side communication part 201 (step ST34).
The information acquired in step ST33 is based on the information accumulated in step ST11 of the sequence diagram shown in FIG.

The control unit 102 of the in-vehicle apparatus 100 receives information via the in-vehicle side communication unit 104 (step ST35), and responds to the simple information when the detailed information is not transmitted with reference to the received information. It is determined that the managed device 300 does not exist. On the other hand, the control unit 102 refers to the received information and determines that there is a management device 300 that responds to the simple information when the detailed information is transmitted. When the detailed information is not transmitted, the control unit 102 reads the collision data stored in the collision data storage unit 103, and retransmits the collision data to the server device 200 via the in-vehicle communication unit 104 (step ST36). . Thereafter, the process proceeds to step ST5 in the sequence diagram shown in FIG.
Note that if the detailed information has been transmitted, the control unit 102 ends the process without retransmitting the collision data. 7 is repeated until detailed information is transmitted to any one of the management apparatuses 300.

  Further, in the sequence diagram of step ST7, the configuration in which the in-vehicle device 100 reads and retransmits the collision data stored in the collision data storage unit 103 is shown, but the buffer area (not shown) of the processing unit 202 of the server device 200 is shown. In the case where the collision data is stored, the control unit 102 may transmit information instructing the server device 200 to retransmit the simple information via the in-vehicle communication unit 104. In this case, the processing unit 202 of the server apparatus 200 returns to the process of step ST6, and transmits management information to the management apparatus 300 based on a retransmission instruction.

Next, a process for releasing the lock process in which the management apparatus 300 has disabled the vehicle will be described. Note that the process of releasing the lock process is performed after the process of step ST16 in the sequence diagram of FIG. 5 is executed.
FIG. 8 is a sequence diagram illustrating the processing operation of the lock release processing of the collision notification system according to the first embodiment.
The management apparatus 300 executes the accident process of step ST16 shown in the sequence diagram of FIG. 5, and when the accident process ends, transmits a lock release instruction to the in-vehicle apparatus 100 (step ST41).

In response to the inquiry, the information indicating whether the detailed information stored in the response information storage unit 204 has been transmitted is read and transmitted to the in-vehicle device 100 via the server side communication unit 201. It is possible to confirm whether there is a management device that responds and the detailed data has been transmitted to the management device that responded. As a result, it is possible to reliably request the management apparatus to handle accidents.

  Further, according to the first embodiment, the control unit 102 refers to the information indicating whether the detailed information transmitted from the server device 200 has been transmitted, and for any management device 300 that has transmitted the simple information. Since the generated collision data is retransmitted to the server device 200 via the in-vehicle communication unit 104 when the detailed information is not transmitted, any management device that has transmitted simple information on the in-vehicle device side It is possible to recognize that there is no response, and the collision data can be retransmitted to the server device. By retransmitting the collision data, it is possible to make a request for the accident process until a management device that can reliably handle the accident process is found.

  Moreover, according to this Embodiment 1, when the collision of a vehicle is detected, the travel monitoring part 105 which monitors driving | running | working of a vehicle based on the positional information on a vehicle is provided, and the control part 102 is a driving | running | working monitoring part. If it is determined at 105 that the vehicle continues to travel, control is performed to output information that prompts the vehicle to stop traveling, and it is determined that the vehicle travels from a point where a vehicle collision has occurred exceeds a preset distance. In such a case, since the vehicle is controlled to stop, it is possible to suppress the vehicle that has collided from running away or running away.

  Further, according to the first embodiment, the control unit 102 performs control for canceling the control for stopping the traveling of the vehicle based on the release instruction input from the management device 300 via the in-vehicle communication unit 104. Since it comprised so, it can suppress that the vehicle which collided escapes. As a result, the parties involved in the collision accident were resolved through discussion, and the colliding vehicle moved from the collision site. It is possible to suppress the occurrence of a problem that the responsibility cannot be pursued even if injuries are found on the side.

  Moreover, according to this Embodiment 1, when the control part 102 performs control which stops driving | running | working of a vehicle, or control which cancels | releases driving | running | working stop of a vehicle, it comprised so that the control which notifies the said control content may be performed. Therefore, the vehicle occupant can confirm beforehand the control content by the vehicle-mounted device.
