That is, if there is something in the vehicle that causes a fire when trying to park, a warning is given at that time. Furthermore, when the smoke sensor 26b detects smoke generated from the ashtray, it is determined that there is a high possibility of fire.

  Further, the fire prediction detection unit 12 detects a fire generated in the vehicle based on the temperature in the vehicle output from the air sensor 25 in the passenger compartment, the presence or absence of smoke in the vehicle, the oxygen concentration in the vehicle, and the transparency of the air in the vehicle. . The occurrence of a fire can also be detected from the in-vehicle image output by the in-vehicle camera 24 and the state of the engine room.

  Then, the fire prediction detection unit 12 evaluates the prediction detection result step by step, and sends the evaluation result to the main control unit 14.

  The main control unit 14 is a control unit that controls the fire prevention device 1 as a whole, and includes a notification processing unit 15 and a fire extinguishing processing unit 16 therein. The notification processing unit 15 selects whether or not to execute notification based on the evaluation result by the fire prediction detection unit 12 and the user position detected by the user position detection unit 13, and executes a notification destination, notification, A notification process is executed by selecting a method and a notification method.

  Similarly, the fire extinguishing processing unit 16 executes the fire extinguishing process based on the evaluation result by the fire prediction detecting unit 12 and the user position detected by the user position detecting unit 13.

  Next, with reference to FIG. 2, the prediction detection process by the fire prediction detection part 12 and the process by the main control part 14 are demonstrated concretely. As shown in the figure, the fire prediction detection unit 12 includes “fire occurrence (judgment level 4)”, “immediately before fire (judgment level 3)”, “high possibility of fire occurrence (judgment level 2)”, “fire” A five-step determination is made: “Possibility of occurrence (determination level 1)” and “No possibility of fire occurrence (determination level 0)”.

  Specifically, the fire prediction detection unit 12 determines that “fire has occurred (judgment level 4)” when it is detected that flames or smoke is generated from components in the passenger compartment or engine room. The fire prediction detection unit 12 determines “immediately before fire (determination level 3)” when it detects that smoke is generated from the passenger compartment or the engine room.

  Similarly, the fire prediction detection unit 12 determines that a “fire occurrence occurs” when the temperature of parts in the vehicle or the engine room is locally high and the oxygen concentration in the vehicle or the transparency of the air in the vehicle has decreased. Is determined to be “high possibility (determination level 2)”.

  In addition, if there is a mistreatment of cigarettes (such as a cigarette that has been ignited with the lid of the ashtray open), there is a risk of explosion at high temperatures such as a lens substitute such as glasses or a lighter. When a certain object is left unattended, it is determined that there is a possibility of fire (judgment level 1), and when a factor that causes a fire is not detected, there is no possibility of fire (judgment level 0) Is determined.

  Here, when the fire prediction detection unit 12 predicts that the lens substitute is left in the vehicle and the sunlight entering the vehicle becomes strong, “the possibility of fire occurrence (judgment level 1)”. To “Large possibility of fire (judgment level 2)”.

  Similarly, if the situation is “Large possibility of fire (judgment level 2)” and there is a combustible material around the vehicle, that is, there is a risk of fire spread, “Just before fire (judgment level 3) To "". Here, the presence or absence of combustible materials around the host vehicle may be detected from the output of the camera 29 outside the vehicle, or may be estimated that there is combustible material when the location of the host vehicle is in a residential area. .

  Next, when the fire prediction detection unit 12 determines “fire occurrence (judgment level 4)”, the notification processing unit 15 notifies the fire department, the center, and the light and sound around the vehicle. All notifications to the terminal owned by the user are executed.

  Specifically, the notification to the fire department is performed via the telephone line or the Internet using the indirect communication device 61. Similarly, notification to the center is also performed via the Internet using the joint communication device 61.

  Further, notification using light and sound to the periphery of the vehicle is realized by the vehicle outside notification system 4 and the lighting system 5. Further, the notification to the terminal owned by the user is realized by the indirect communication device 61 or the direct communication device 62.

  Further, when the fire prediction detection unit 12 determines that “fire has occurred (judgment level 4)”, the fire extinguishing processing unit 16 executes the fire extinguishing process, and also unlocks the door, opens the window, Perform recording and transmission.

  Unlocking the door has the effect of facilitating fire fighting work by fire department staff. Moreover, the opening of the window has the effect of notifying the vehicle periphery by taking it out of the vehicle through the opened window.

  Video recording and transmission has the effect of notifying the state of the fire by photographing the interior of the vehicle with the camera 28 outside the vehicle and transmitting it to the user, center, and fire department. Here, depending on the progress of the fire, the camera 28 outside the vehicle and the communication system 6 may be broken.

  Next, when the fire prediction detection unit 12 determines “immediately before the fire (determination level 3)”, the notification processing unit 15 notifies the fire department, the center, and the light and sound around the vehicle. All notifications to the terminal owned by the user are executed.

  And the fire extinguishing process part 16 performs the operation | movement according to a predetermined setting. For example, at the stage of determination level 3, as in determination level 4, fire extinguishing processing, door unlocking, window opening, video recording and transmission may all be executed, or video recording and transmission only. It is good also as performing. In addition, an instruction for a process to be executed at the time of notification to the user may be obtained, and a fire extinguishing process may be started when there is no response within a predetermined time.

  Also, for example, when the remaining amount of fire extinguishing agent is detected and the remaining amount is sufficient and can be extinguished by the own vehicle, a fire extinguishing process is executed. May notify the fire department.

  Furthermore, the possibility of fire spread is determined from the situation around the vehicle. If there is no possibility of fire spread, only notification to the user is executed, and if there is a possibility of fire spread, the fire extinguishing process is started. May be.

  Next, when the fire prediction detection unit 12 determines that “the possibility of fire occurrence is high (determination level 2)”, the notification processing unit 15 notifies the terminal around the vehicle by light and sound notifications to the vehicle. Execute the notification.

  And the fire extinguishing process part 16 performs the operation | movement according to a predetermined setting. Here, it is preferable to differentiate between the content of the operation set for the determination level 2 and the content of the operation set for the determination level 3.

  Next, when the fire prediction detection unit 12 determines that “the possibility of fire occurrence (determination level 1)”, the notification processing unit 14 is based on the distance of the user to the vehicle detected by the user position detection unit 13. When the user is in the vicinity of the vehicle, notification to the user is performed by the outside notification system 4 or the lighting system 5, and when the distance between the user and the vehicle is long, notification is performed by transmission to the terminal possessed by the user To do.

  That is, in the determination levels 4 to 2, the notification to the periphery of the vehicle is executed for the purpose of notifying the third party around the vehicle that there is a risk of a vehicle fire. Since it is a very early prediction, unnecessary notification to a third party is avoided and it is used as a means for notifying only the user.

  In addition, when the fire prediction unit 12 determines that “no possibility of fire occurrence (determination level 0)”, the notification process or the fire extinguishing process is not executed.

  By the way, the notification processing unit 15 autonomously executes the notification process when it is determined by the fire prediction detection unit 12 that there is a possibility of a fire or a fire has occurred (judgment level 1 or higher). Not only when a confirmation request from the user is accepted, the notification process is executed.

  In the response notification to the confirmation request, the notification content is changed based on the determination result by the fire prediction detection unit 12. Specifically, as shown in FIG. 3, when there is no possibility of a fire (judgment level 0), the terminal owned by the user is notified only by text. As this sentence, for example, “no danger of fire” may be used.

  Further, in the case of determination level 1, the notification processing unit 15 transmits an image in the vehicle in addition to the text (for example, “There is a possibility of fire”), and assists the user in determining the risk. .

  Furthermore, in the case of determination level 2, the notification processing unit 15 assists the user in determining the risk by transmitting data such as oxygen concentration and transparency in addition to text and images. In addition, in the case of judgment level 2, the judgment result by the fire prediction detection unit 12 is notified, such as “Large possibility of fire.” And “Do you want to contact the fire department?” Or “Fire extinguishing” Send a message such as "Do you want?" When the user receives a notification to the fire department or an instruction to start extinguishing the fire, a communication to the fire department or a fire extinguishing process is executed.

  At decision level 3, since the occurrence of a fire is almost certain, the notification processing unit 15 notifies the user of the situation by text or image and transmits the image to the center. The notification content to the user at this time is, for example, “fire is occurring” or the like, and also requests an instruction to contact the fire department or execute fire extinguishing.

  In addition, after detecting the situation of the judgment level 4, that is, the occurrence of a fire, since the notification is executed to the user at the time of detection, it is excluded from the confirmation response notification.

  It continues and the fire extinguishing process by the fire prevention apparatus 1 is demonstrated. FIG. 4 is a flowchart showing a processing operation when the main control unit 14 executes the fire extinguishing process. This process flow is a process that is started when the execution of the fire extinguishing process is determined from the determination result of the fire prediction detection unit 12, or when the execution of the fire extinguishing process is instructed by the user.

  First, when the fire extinguishing process is started, the main control unit 14 starts recording the image information in the vehicle and transmitting it to the center (step S101). This recording / transmission of image information indicates a fire situation and is regularly recorded / transmitted from the start of fire extinguishing in preparation for damage to the in-vehicle camera 24 and the communication system 6 due to fire.

  Next, the main control unit 14 operates the locking mechanism 8 to release the door lock and open the window (step S102), thereby supporting fire fighting work by a fire department staff and the like, and generating a fire around the vehicle. Notice.

  Next, for example, washer fluid, cooling water, etc. are sprayed into the vehicle as a fire extinguisher and fire extinguishing processing is executed (step S103). Then, it is determined whether or not the extinguishing is completed (extinguishing) based on the temperature in the vehicle and the image information (step S104), and the extinguishing process (step S103) is continued until the extinguishing is completed.

  As a result, if fire extinguishing is completed (step S104, Yes), the main control unit 14 then determines whether or not the vehicle is ready to travel (step S105). Specifically, when a mechanism necessary for vehicle travel is damaged by a fire, or when the interior of the vehicle is flooded, or by using something necessary for traveling such as cooling water as a fire extinguisher, When the amount is less than the required amount, it is determined that “travel is impossible”.

  If the vehicle is capable of traveling (step S105, Yes), the main control unit 14 notifies the user and a predetermined contact address such as the fire department that fire extinguishing is completed and the vehicle can travel ( Step S106) and the process ends.

  On the other hand, when the vehicle cannot travel (No at Step S105), the main control unit 14 notifies the user and a predetermined contact address such as the fire department that the fire is completed and the vehicle cannot travel. (Step S107), and the process ends. At this time, it is necessary to move the vehicle and repair it. Therefore, you may automatically notify JAF (JAPAN AUTOMOBILE FEDERATION) etc. in addition to the contact information, and confirm whether to notify the user. You may ask for.

  As described above, when the vehicle is parked, the fire prevention device 1 for a vehicle according to this embodiment detects the possibility before the occurrence of a fire by monitoring the situation inside the vehicle and takes appropriate measures. By selecting and executing, it is possible to prevent vehicle fire and reduce damage.

  In the present embodiment, the configuration in which various types of detection means such as the in-vehicle camera 24 are used exclusively by the fire prevention device 1 has been described as an example. However, these detection means may be other in-vehicle devices such as anti-theft devices and air conditioners. It can be shared with devices.
