Description

Technical Field

[0001] The present invention relates to a docking device and method for a vehicle cooperative fire extinguishing system, and also relates to a docking device and method for a vehicle cooperative fire extinguishing system for docking surrounding vehicles with a fire vehicle to supply fire water to the fire vehicle. Background Art

[0002] Recently, as the use of environmentally friendly vehicles such as electric vehicles or fuel cell vehicles has increased, the risk of fires caused by external impact or internal short circuits in batteries or high-voltage wires installed in these vehicles has also increased.

[0003] Environmentally friendly vehicles have the common feature of using electricity stored in batteries (or "battery packs") to drive motors, so they can be broadly referred to as electric vehicles. In such electric vehicles, a high-voltage battery pack is installed to supply power to the motors. The high-voltage battery pack is repeatedly charged and discharged during vehicle travel, thereby supplying power to power electronic systems including the motors.

[0004] The battery pack of an electric vehicle generally includes a battery box and a plurality of battery modules arranged in the battery box. In addition, the battery pack also includes a configuration for preventing fire by cutting off a fuse or cutting off a relay connected to an inverter when an internal short circuit or overcurrent occurs.

[0005] However, during the driving of electric vehicles, fires may occur in battery packs, wires, etc. due to various reasons such as collision or component failure. When the fire is not properly extinguished, the fire may cause the vehicle to burn, which may cause huge property losses and personal injuries.

[0006] Due to the structure and components of the battery pack, a battery pack fire may spread in a short period of time. For public transportation vehicles with a large number of passengers, such as buses, a quick fire-fighting response is crucial to the safety of passengers. Once the initial fire-fighting response fails, the fire may cause a major disaster.

[0007] However, the only known method of dealing with fire is to use a fire extinguisher provided in the vehicle. Even in this case, if the driver does not use the fire extinguisher in time, the initial fire extinguishing reaction will fail, and therefore, the fire may spread throughout the vehicle, and the risk of personal injury may increase. Even if the driver or passengers in the vehicle quickly realize that a fire has occurred, it may be difficult to extinguish the fire with only the small fire extinguisher provided in the vehicle.

[0008] Fire water can be supplied to the vehicle if a standpipe system is set up around the vehicle or a fire truck is near the fire scene, but otherwise it is difficult to extinguish the fire in the early stages.

[0009] Therefore, there is an urgent need to take measures to extinguish fires that occur in moving vehicles more quickly at an early stage.

[0010] The information contained in the background technology of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and shall not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art. Summary of the invention

[0011] Aspects of the present disclosure are directed to providing a technology that is currently being studied and can quickly extinguish a fire in an environmentally friendly vehicle in the early stages of a fire through cooperation with surrounding vehicles.

[0012] According to ongoing research, spraying fire water on a burning vehicle from the outside is almost not conducive to extinguishing the fire. In order to extinguish the fire in the early stages, it is effective to spray fire water directly on the inside of the burning vehicle.

[0013] Therefore, it is necessary to establish a docking structure between the burning vehicle and surrounding vehicles so as to supply fire water directly from the surrounding vehicles to the interior of the burning vehicle.

[0014] Various aspects of the present disclosure are intended to provide a docking device and method for a vehicle cooperative fire extinguishing system, which docks surrounding vehicles with a vehicle on fire so as to supply fire water to the vehicle on fire, thereby quickly extinguishing a fire occurring in the vehicle on fire through cooperation with surrounding vehicles.

[0015] Various aspects of the present disclosure are intended to provide a docking device for a vehicle cooperative fire extinguishing system, including: a fire water inflow pipe, arranged in a first vehicle to receive fire water; a fire water supply pipe, arranged in a second vehicle to be configured to dock with the fire water inflow pipe and moved to a position capable of docking with the fire water inflow pipe by the drive of the second vehicle; and a height adjustment module, arranged in the second vehicle and configured to adjust the height of the fire water supply pipe to be consistent with the height of the fire water inflow pipe.

[0016] In an exemplary embodiment of the present disclosure, the height adjustment module may include a first magnet arranged on a fire water supply pipe, and a second magnet mounted on a second vehicle and configured to be separated from the first magnet in a vertical direction, one of the first magnet and the second magnet may be a permanent magnet, and the remaining one of the first magnet and the second magnet may be an electromagnet configured to generate a magnetic force to move the fire water supply pipe in a vertical direction when current is applied to the electromagnet.

[0017] In another exemplary embodiment of the present disclosure, the current value applied to the electromagnet can be determined based on the movement amount of the fire water supply pipe, and the movement amount of the fire water supply pipe can be the vertical movement amount of the fire water supply pipe to position the fire water supply pipe at the same height as the fire water inflow pipe.

[0018] In various exemplary embodiments of the present disclosure, horizontal movement of the fire water supply pipe may be restricted by a stopper provided in the second vehicle.

[0019] In various exemplary embodiments of the present disclosure, the stopper may include a guide groove configured such that a connector provided on the fire water supply pipe is inserted into the guide groove, and the guide groove may be retracted into the stopper in a vertical direction.

[0020] In various other exemplary embodiments of the present disclosure, when docking between the fire water inflow pipe and the fire water supply pipe is completed, the stopper may be moved in a direction separating from the connector of the fire water supply pipe by driving a first motor provided in the second vehicle.

[0022] In another embodiment, a spring member in a compressed state provided on the connector may apply pressure to the extension tube in the extension direction.

[0023] In another embodiment, a flap adjacent to the joint of the extension pipe may support the spring member in a compressed state, and the flap may be configured to open or close a water supply pipe opening provided in an outer body of the second vehicle.

[0024] In another embodiment, the baffle may open the water supply pipe opening by driving the second motor when the fire water supply pipe is positioned at a position capable of docking with the fire water inflow pipe.

[0025] In another embodiment, a pressure sensor configured to measure the pressure applied to a joint connected to the fire water inflow pipe can be provided on the extension pipe, and whether the docking between the fire water inflow pipe and the extension pipe is performed can be determined based on the pressure value measured by the pressure sensor.

[0026] In another embodiment, the fire-fighting water inflow pipe may be connected to a battery box of a battery pack provided in the first vehicle, and the fire-fighting water supplied to the fire-fighting water inflow pipe through the fire-fighting water supply pipe may flow into the battery box.

[0027] Various aspects of the present disclosure are intended to provide a docking method for a vehicle collaborative fire extinguishing system, comprising: at the request of a first vehicle including a fire water inflow pipe, moving a second vehicle including a fire water supply pipe to a first position within a predetermined distance from the first vehicle; when the second vehicle reaches the first position, based on position information of the fire water inflow pipe, by driving the second vehicle and operating a height adjustment module disposed in the second vehicle, moving the fire water supply pipe to a second position capable of docking with the fire water inflow pipe; when the fire water supply pipe is positioned at the second position, by opening a baffle configured to open or close a water supply pipe opening disposed in an outer body of the second vehicle, extending an extension pipe disposed in the fire water supply pipe toward the fire water inflow pipe; and docking the extended extension pipe with the fire water inflow pipe to supply fire water to the fire water inflow pipe.

[0028] In an exemplary embodiment of the present disclosure, moving the fire water supply pipe to a second position may include: moving the second vehicle so that the horizontal position of the fire water supply pipe is consistent with the horizontal position of the fire water inflow pipe; and moving the fire water supply pipe in a vertical direction through a height adjustment module so that the vertical position of the fire water supply pipe is consistent with the vertical position of the fire water inflow pipe.

[0029] In another exemplary embodiment of the present disclosure, a fire water supply pipe may include: a flexible hose including a first end portion connected to a second vehicle and configured to store a water tank for storing fire water; a connector disposed at the second end portion of the flexible hose and provided with a first magnet mounted on the connector; and an extension pipe connected to the flexible hose via the connector, configured to extend along a longitudinal direction of the extension pipe, and a spring member in a compressed state disposed on the connector applies pressure to the extension pipe along the extension direction.

[0030] In various exemplary embodiments of the present disclosure, a baffle adjacent to the end of the extension pipe supports the spring component in a compressed state, and when the extension pipe is extended toward the fire water inflow pipe, when the baffle opens the water supply pipe opening, the extension pipe can be extended toward the fire water inflow pipe by the elastic restoring force of the spring component.

[0031] In various exemplary embodiments of the present disclosure, docking the extended extension pipe with the fire water inflow pipe may include determining whether the docking between the fire water inflow pipe and the fire water supply pipe is completed based on a pressure value measured by a pressure sensor arranged on the extension pipe of the fire water supply pipe, and when the pressure value measured by the pressure sensor is greater than or equal to the set pressure value, it can be determined that the docking between the fire water inflow pipe and the fire water supply pipe is completed.

[0032] In various other exemplary embodiments of the present disclosure, the docking method may further include: when the docking between the fire water inflow pipe and the fire water supply pipe is completed, a block configured to limit the horizontal movement of the fire water supply pipe is separated from the fire water supply pipe; by moving the second vehicle in a direction away from the first vehicle, ensuring a safe distance of the second vehicle; and supplying fire water in a water tank provided in the second vehicle to the fire water inflow pipe through the fire water supply pipe, the fire water inflow pipe can be connected to a battery box of a battery pack provided in the first vehicle, and the fire water supplied to the fire water inflow pipe through the fire water supply pipe can flow into the battery box.

[0047] Reference will now be made in detail to various embodiments of the present disclosure, examples of which are shown in the accompanying drawings and described below. Although the present disclosure will be described in conjunction with exemplary embodiments of the present disclosure, it should be understood that this description is not intended to limit the present disclosure to those exemplary embodiments of the present disclosure. On the other hand, the present disclosure is intended to cover not only the exemplary embodiments of the present disclosure, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit and scope of the present disclosure as defined in the appended claims.

[0048] Hereinafter, reference will be made in detail to various embodiments of the present disclosure, examples of which are shown in the accompanying drawings and described below. The elements included in the drawings may be schematically illustrated to clearly illustrate exemplary embodiments of the present disclosure and may differ from their actual implementation forms.

[0049] In the following description of the embodiments, terms such as "first" and "second" are only used to describe various elements, and these elements should not be interpreted as being limited by these terms. These terms are only used to distinguish one element from other elements. For example, without departing from the scope of the present disclosure, the first element described below may be referred to as the second element, and similarly, the second element described below may be referred to as the first element.

[0050] Various embodiments of the present disclosure are directed to a coordinated fire extinguishing system for vehicles, which can quickly extinguish a fire occurring in a vehicle in an early stage through cooperation between vehicles. Various aspects of the present disclosure are intended to provide a docking structure and method required for extinguishing a fire in an early stage between vehicles.

[0051] Figure 1 2 is a diagram showing a fire vehicle 10 and surrounding vehicles 20 performing a coordinated fire extinguishing process according to an exemplary embodiment of the present disclosure, Figure 2 1 is a block diagram showing main components installed in a fire starting vehicle 10 and a fire extinguishing vehicle 20 among components of a vehicle cooperative fire extinguishing system according to an exemplary embodiment of the present disclosure. In the following description, a vehicle in which a fire occurs and is thus extinguished will be referred to as a "fire starting vehicle".

[0052] The fire extinguishing system according to the exemplary embodiment of the present disclosure can be used to extinguish a fire occurring in an environmentally friendly vehicle. In addition, the fire extinguishing system according to the exemplary embodiment of the present disclosure is configured to extinguish the fire in the fire vehicle using fire water supplied from one of the surrounding vehicles 20 after docking with the fire vehicle 10. Here, the fire in the fire vehicle 10 can be extinguished through cooperation between multiple vehicles.

[0053] Here, the fire vehicle 10 may be an environmentally friendly vehicle, for example, an electric vehicle or a fuel cell vehicle equipped with a high voltage battery. That is, the present disclosure may be used to extinguish a fire occurring in an electric vehicle or a fuel cell vehicle, and the fire occurring in the vehicle may be a fire occurring in the vehicle battery.

[0054] In an exemplary embodiment of the present disclosure, the vehicle 20 participating in fire fighting is a vehicle that can dock with the fire vehicle 10, and is used to supply the fire vehicle 10 with fire water stored in the water tank 35. In addition, in an exemplary embodiment of the present disclosure, the vehicle 20 participating in fire fighting is a vehicle that can communicate with the fire vehicle 10 or an external system, and is a vehicle that can cooperate with the fire vehicle 10 to fight the fire while exchanging necessary information with the fire vehicle 10 through communication.

[0055] For example, in an exemplary embodiment of the present disclosure, the vehicle 20 participating in fire fighting may be a fuel cell vehicle, which may store waste water generated and discharged by the fuel cell stack 31 in a water tank 35 ( Figure 3 ), the waste water can then be supplied as fire water to the fire vehicle 10. In addition, in an exemplary embodiment of the present disclosure, the vehicle 20 participating in fire fighting can be an autonomous driving vehicle, which can supply the fire water stored in the water tank 35 to the fire vehicle 10 and can be driven autonomously.

[0056] The fire extinguishing system according to various exemplary embodiments of the present disclosure is arranged in a fire vehicle 10, and includes a fire detector 11 arranged in the fire vehicle 10 and configured to detect a fire occurring in the fire vehicle 10, a controller 12 installed in the fire vehicle 10 and configured to enter a fire extinguishing mode to execute a control process for extinguishing the fire when it is determined that a fire occurs in the fire vehicle 10, and a communication device 13 installed in the fire vehicle 10 to communicate with surrounding vehicles 20 and external systems (for example, a server of a fire station 70).

[0057] In an exemplary embodiment of the present disclosure, the fire detector 11 may be a temperature sensor 5 ( Figure 4 A fire detection circuit that outputs an electrical signal due to the melting of the cladding material when it comes into contact with flames or at high temperatures.

[0058] The controller 12 may be configured to determine that a fire has occurred in the vehicle 10 when the detected temperature indicated by the signal received from the temperature sensor 4 is equal to or greater than a predetermined temperature, when the detected carbon monoxide concentration indicated by the signal received from the gas detector is equal to or greater than a set concentration, or when an electrical signal is input from the fire detection circuit.

[0059] In an exemplary embodiment of the present disclosure, the controller 12 is configured to execute a predetermined control process for extinguishing a fire in the event of a fire in the vehicle itself, which process will be described below, namely, controlling to issue a warning about the occurrence of a fire to the inside and outside of the vehicle, or sending fire occurrence information through the communication device 13 to notify the outside of the fire occurrence and request fire extinguishing.

[0060] To this end, the fire extinguishing system according to the exemplary embodiment of the present disclosure may further include a warning device, which, after determining that a fire has occurred, is operated by a control signal output by the controller 12 of the fire vehicle 10 and issues a warning about the occurrence of a fire. The warning device may be a warning light or a warning sound output device.

[0061] The communication device 13 of the fire vehicle 10 is configured to perform communication with the surrounding vehicles 20 and an external system (e.g., a server of the fire station 70 located outside the fire vehicle 10). As the communication device 13 of the fire vehicle 10, any known wireless communication device can be used to perform communication between the corresponding vehicle and the outside through wireless communication without being limited by a communication method.

[0062] In addition, the fire extinguishing system according to various exemplary embodiments of the present disclosure includes a fire extinguishing vehicle 20 that can supply fire water and includes a communication device 22 that can communicate with the outside. The fire extinguishing vehicle 20 refers to a vehicle that supplies fire water to the fire vehicle 10 after docking with the fire vehicle 10 to extinguish the fire in the fire vehicle 10 among the surrounding vehicles 20 located around the fire vehicle 10. That is, the fire extinguishing vehicle 20 refers to a vehicle that participates in fire extinguishing among the surrounding vehicles 20 located around the fire vehicle 10.

[0063] Figure 3 1 is a block diagram showing components installed in a fire extinguishing vehicle 20 of a cooperative fire extinguishing system for a vehicle according to an exemplary embodiment of the present disclosure. In an exemplary embodiment of the present disclosure, the surrounding vehicles 20 that can participate in fire extinguishing can be fuel cell vehicles as described above, and more specifically, can be fuel cell vehicles that can travel automatically.

[0064] Reference Figure 3 The fuel cell system 30 is installed in the fuel cell vehicle, and the fuel cell system 30 includes a fuel cell stack 31, a hydrogen supply device 32 configured to supply hydrogen provided as a fuel gas, an air supply device 33 configured to supply air including oxygen provided as an oxidant gas, and other accessories and auxiliary devices 34 required for operating the fuel cell. In addition, a drive motor 26 for driving is generally installed in the fuel cell vehicle, and the drive motor 26 is operated by receiving the power generated by the fuel cell stack 31 and the power generated by the battery (refer to Figure 2 ).

[0065] In addition, a water tank 35 configured to store waste water generated and discharged by the fuel cell stack 31 and a pump 36 configured to extract the waste water stored in the water tank 35 and then supply the waste water to the fire water supply pipe 40 are installed in the fire fighting vehicle 20 in the exemplary embodiment of the present disclosure.

[0066] In addition, when the fire-fighting vehicle 20 in the exemplary embodiment of the present disclosure is a fuel cell vehicle that can travel automatically, as shown in FIG. Figure 2 As shown, a general device for automatic driving is installed in the fire fighting vehicle, for example, an automatic driving controller 25 configured to perform automatic driving control and an automatic driving sensor 24 configured to obtain various information required for performing automatic driving control. For example, the automatic driving sensor 24 may include a camera configured to obtain image information required for automatic driving control.

[0067] In various exemplary embodiments of the present disclosure, the fire extinguishing vehicle 20 is located within a set distance around the fire vehicle 10, receives fire occurrence information sent by the fire vehicle 10 through the communication device 22, and moves to a position where the fire extinguishing vehicle 20 can dock with the fire vehicle 10 to participate in fire extinguishing.

[0068] In an exemplary embodiment of the present disclosure, the communication device 22 of the surrounding vehicles 20 that can participate in fire extinguishing can be the same as the communication device 13 of the fire-occurring vehicle 10, and can be installed in the surrounding vehicles 20 to communicate with the communication device 13 of the fire-occurring vehicle 10 and an external system (e.g., a server of the elements 40, 50, and 60) (in Fig.12 A wireless communication device for performing wireless communication.

[0069] It is expected that connected vehicles that communicate in real time with other vehicles, traffic and communication infrastructure, and pedestrian terminals will become popular along with autonomous vehicles, and a fire extinguishing system according to an exemplary embodiment of the present disclosure may be a system including such connected vehicles and autonomous vehicles, or a system using these vehicles.

[0070] In various exemplary embodiments of the present disclosure, when the controller 12 of the fire vehicle 10 determines that a fire has occurred in the vehicle 10 through the fire detector 11, the controller 12 transmits fire occurrence information through the communication device 13, including a fire occurrence signal notifying the occurrence of a fire, a fire extinguishing request signal, vehicle position information, etc. The vehicle position information may include position information of the fire vehicle 10 and position information of a fire water inlet pipe 14 provided in the fire vehicle 10.

[0071] Here, the controller 12 and the communication device 13 of the fire vehicle 10 may be configured to transmit the fire occurrence information to all surrounding vehicles 20 located within a set radius distance (eg, 5 kilometers) from the location of the fire vehicle 10 .

[0072] In addition, the controller 12 and the communication device 13 of the fire vehicle 10 can also be set to send the fire occurrence information to the nearest fire station 70. In this case, the fire occurrence information can be sent to the fire station 70, including the vehicle position information (i.e., the fire vehicle position information), the driver information, and the fire occurrence signal notifying the fire occurrence. Therefore, after receiving the fire occurrence information, the fire station 70 can dispatch a fire truck to the fire vehicle 10.

[0073] Here, when the fire station 70 receives the fire occurrence information, the fire station 70 can try to make a telephone call with the driver using the driver information of the fire vehicle 10, and can dispatch a fire truck to the fire vehicle 10 after confirming the fire occurrence through the telephone call with the driver.

[0074] In various exemplary embodiments of the present disclosure, the controller 10 of the fire vehicle 10 utilizes navigation information including map information and real-time traffic information to confirm the location of the fire station 70 and the radial distance to the fire station 70 based on the current location of the fire vehicle 10, and is configured to determine the required arrival time, that is, the time required for the fire truck to arrive at the current location of the fire vehicle 10.

[0075] When the radius distance to the fire station 70 is within the set radius distance based on the current position of the fire vehicle 10 (i.e., the real-time position), and the arrival time required for the fire truck to reach the current position of the fire vehicle 10 is less than or equal to the set time (e.g., 15 minutes), the controller 12 of the fire vehicle 10 can be set not to send fire occurrence information to the surrounding vehicles 20.

[0076] Here, the required arrival time reflecting real-time traffic information may be used. The reason why the fire occurrence information is not transmitted to the surrounding vehicles 20 when the required arrival time is less than or equal to the set time is that the fire can be extinguished in the early stage only by dispatching a fire truck.

[0077] When the fire station 70 is outside the set radius or the time required for the fire truck to arrive exceeds the set time, the controller 12 of the fire vehicle 10 sends fire occurrence information to surrounding vehicles 20 within the set radius to request fire extinguishing.

[0078] Among the surrounding vehicles 20 that can participate in fire extinguishing, the position information of the fire vehicle 10 is displayed on the vehicle display 23, and the required driving time (i.e., the time required for the surrounding vehicles 20 to travel from the current position of the surrounding vehicles 20 to the position of the fire vehicle 10) is determined as the time reflecting the real-time traffic conditions, and the time is displayed on the vehicle display 23.

[0079] In addition, information asking whether to participate in fire extinguishing and a pop-up window configured to allow the driver to select and input whether to participate in fire extinguishing can also be displayed on the display 23. Here, the display 23 can be a vehicle-mounted display, which displays navigation information including map information and location information in a state interconnected with the navigation system.

[0080] Furthermore, the display 23 may be a display connected to a separate input unit configured to allow the driver to select and input whether to participate in fire extinguishing, or a touch screen type display including a configuration integrated with the input unit.

[0081] In this way, a pop-up window configured to allow the driver to select and input whether to participate in fire extinguishing can be displayed on the display 23 of a surrounding vehicle 20 that is located around the fire vehicle 10 and receives fire occurrence information from the fire vehicle 10, and then the driver can select and input whether to participate in fire extinguishing in the pop-up window displayed on the display 23.

[0082] Here, a participation selection button may be displayed in the pop-up window, and the driver may choose whether to participate in fire extinguishing by touching the participation selection button displayed in the pop-up window.

[0083] Furthermore, when the driver of the surrounding vehicle 20 receiving the fire occurrence information selects and inputs participation in fire extinguishing, a fire extinguishing participation signal indicating the intention to participate in fire extinguishing may be transmitted to the fire vehicle 10 through the communication device 22 .

[0084] Therefore, the controller 12 of the fire vehicle 10 sets the surrounding vehicle 20 that has sent the fire extinguishing participation signal as the fire extinguishing vehicle 20 based on the fire extinguishing participation signal received through the communication device 13. Here, the controller 12 of the fire vehicle 10 sends a fire extinguishing request signal to the fire extinguishing vehicle 20 through the communication device 13.

[0085] Furthermore, a water level sensor 35a may be provided in a water tank 35 configured to store firefighting water (ie, a water tank 35 configured to store waste water in a fuel cell vehicle) of a surrounding vehicle 20 that may participate in fire fighting.

[0086] Here, the controller 21 of the surrounding vehicle 20 obtains the current water level information of the wastewater in the water tank 35 from the signal of the water level sensor 35a, and only when the current water level of the wastewater in the water tank 35 is equal to or greater than the predetermined water level, the driver is allowed to select and input whether to participate in fire extinguishing.

[0087] To this end, only when the acquired current water level of the waste water in the water tank 35 is equal to or greater than a predetermined water level, the controller 21 of the surrounding vehicle 20 may activate the participation selection button in the pop-up window displayed on the display 23 .

[0088] In addition, in various exemplary embodiments of the present disclosure, the controller 12 of the fire vehicle 10 can only designate a set number of vehicles 20 in the order of arrival among the surrounding vehicles 20 that have sent fire extinguishing participation signals as fire extinguishing vehicles 20, and can only send fire extinguishing request signals to the set number of fire extinguishing vehicles 20.

[0089] While the fire extinguishing vehicle 20 is selected, when the number of surrounding vehicles 20 designated as the fire extinguishing vehicle 20 reaches a set number, the controller 12 of the fire vehicle 10 transmits a signal indicating that participation in fire extinguishing is not permitted to the remaining surrounding vehicles 20 .

[0090] In the exemplary embodiment of the present disclosure, the reason why the number of fire extinguishing vehicles 20 is limited to a set number is to prevent a large number of vehicles from participating in fire extinguishing and causing traffic congestion.

[0091] In an exemplary embodiment of the present disclosure, the controller 12 of the fire vehicle 10 can adjust the set number of fire extinguishing vehicles 20 according to real-time traffic conditions and road conditions. For example, the controller 12 of the fire vehicle 10 can receive and use navigation information (information provided by a navigation system), and can be configured to determine the set number of fire extinguishing vehicles 20 based on the average vehicle speed information on surrounding roads in the navigation information.

[0092] Here, the set number of fire-fighting vehicles 20 in the corresponding road section divided according to the average vehicle speed may be predetermined, and when an actual fire occurs, the corresponding set number of vehicles may be determined according to the average vehicle speed of the surrounding roads, and may be used to limit the number of fire-fighting vehicles 20. In a road section where the average vehicle speed is low, the controller 12 may set the number of fire-fighting vehicles 20 to a lower value.

[0093] In various exemplary embodiments of the present disclosure, when the surrounding vehicle 20 is finally selected as the fire extinguishing vehicle 20 through the driver's selection and input of participating in the fire extinguishing, the automatic driving controller 25 can perform automatic driving control to drive the fire extinguishing vehicle 20 to the position of the fire vehicle 10 in the automatic driving mode. Specifically, the position of the fire vehicle 10 can indicate the position where the fire extinguishing vehicle 20 can dock with the fire vehicle 10.

[0094] In addition, when the fire extinguishing vehicle 20 arrives at the location of the fire vehicle 10 , the docking between the vehicles 10 and 20 is achieved by connecting the fire water channels of the vehicles 10 and 20 to supply the fire water of the fire extinguishing vehicle 20 to the fire vehicle 10 .

[0095] When multiple fire-fighting vehicles 20 arrive at the location of the fire vehicle 10, the fire-fighting vehicle 20 that arrives first docks with the fire vehicle 10 and supplies fire water to the fire vehicle, while the remaining fire-fighting vehicles 20 that arrive at the location of the fire vehicle 10 are controlled at positions around the fire vehicle 10 and stand by in automatic driving mode.

[0096] In various exemplary embodiments of the present disclosure, as described above, the fire may be a fire occurring in a battery, and more specifically, may be a fire occurring in a battery pack.

[0097] Figure 4 2 is a view exemplarily showing components provided in a battery pack 1 of a fire-occurring vehicle 10 of a vehicle cooperative fire extinguishing system according to various exemplary embodiments of the present disclosure. Figure 4 A fire-fighting water inflow pipe 14 and a nozzle 4 configured to supply fire-fighting water, as well as a fire detector 11 and a battery pack 1 are shown.

[0098] In an exemplary embodiment of the present disclosure, a battery pack 1 may include a battery box 2 and a battery module 3 disposed in the battery box 2. The battery module 3 accommodated in the battery box 2 includes a plurality of battery cells.

[0099] In an exemplary embodiment of the present disclosure, the battery box 2 is configured to include a structure including an internal space that can be filled with fire water. To this end, the internal space of the battery box 2 accommodating the battery module 3 may be sealed.

[0100] That is, the structure of the battery case 2 can seal the battery module 3 while surrounding the battery module 3 including the battery cells, so the inner space of the battery case 2 can be filled with fire water.

[0101] A fire water inlet pipe 14 configured to inject fire water is connected to the battery box 2 , and fire water supplied from a fire extinguishing vehicle 20 docked with the fire vehicle 10 fills the internal space of the battery box 2 through the fire water inlet pipe 14 , thereby extinguishing the fire occurring in the battery module 3 .

[0102] As described above, the present disclosure can extinguish a fire occurring in the internal space of the battery box 2 surrounding the battery module 3, and can extinguish the fire by supplying fire water to the internal space of the battery box 2 to fill the internal space of the battery box 2. The fire water filling the internal space of the battery box 2 maintains a cool state of the battery cell, thereby preventing the battery cell from reigniting and thermal runaway.

[0103] like Figure 4 As shown, multiple battery packs 1 can be installed in a vehicle. In this case, when a nozzle 4 for battery fire extinguishing is provided in each of the corresponding battery packs 1, a fire water inlet pipe 14 connected to a fire water supply pipe 40 of a fire extinguishing vehicle 20 branches toward the corresponding battery pack 1 at a downstream position of a control flow valve 15, and the branch fire water inlet pipe 14' is connected to the nozzle 4 for battery fire extinguishing of the corresponding battery pack 1.

[0104] Therefore, the controller 12 of the fire vehicle 10 is based on the fire detector 11 ( Figure 2 In Figure 4 The signal of the temperature sensor 5) in the battery pack 1 where the fire occurs is determined, and is configured to control the opening of the flow control valve 15 to open the branch fire water inflow pipe 14' connected to the battery pack 1 where the fire occurs.

[0105] When fire water is supplied to the corresponding battery pack 1 from the fire-fighting vehicle 20 that has been docked with the fire vehicle 10 through the fire water inlet pipe 14, the fire water can be sprayed into the internal space of the battery box 2 through the nozzle 4 in the battery pack 1 where the fire has occurred, thereby filling the internal space of the battery box 2.

[0106] exist Figure 4 , reference numeral 5 denotes a temperature sensor, and the temperature sensor 5 corresponds to a fire detector for detecting a fire occurring in the battery pack 1. Similarly, the fire detector 11 ( Figure 2 In the middle) it can also be a temperature sensor 5.

[0107] Furthermore, in an exemplary embodiment of the present disclosure, the surrounding vehicles 20 wirelessly receive the fire occurrence information transmitted by the fire vehicle 10, and the fire extinguishing vehicle 20 selected among the surrounding vehicles 20 receiving the fire occurrence information moves around the fire vehicle 10 to participate in fire extinguishing.

[0108] Here, multiple fire-fighting vehicles 20 can communicate with the fire vehicle 10 to participate in fire-fighting while exchanging information with the fire vehicle 10, and multiple fire-fighting vehicles 20 that arrive at the location of the fire vehicle 10 to extinguish the fire can dock with the fire vehicle 10 in turn to supply fire-fighting water.

[0109] That is, the fire extinguishing vehicle 20 that arrives first can dock with the fire vehicle 10 and then supply fire water to the fire vehicle 10. When the fire extinguishing vehicle 20 runs out of the fire water stored therein, the fire extinguishing vehicle 20 can stop the operation of the pump 36 and then automatically separate from the fire vehicle 10. Thereafter, the next fire extinguishing vehicle 20 can dock with the fire vehicle 10 and then supply fire water to the fire vehicle 10.

[0110] Here, the order in which the fire-fighting vehicle 20 docks with the fire vehicle 10 and supplies fire-fighting water to the fire vehicle 10 can be set to the order of arrival at the position of the fire vehicle 10. The fire-fighting vehicle 20 docks with the fire vehicle 10 in the order of arrival and supplies fire-fighting water to the fire vehicle 10 to extinguish the fire in the fire vehicle 10.

[0111] In addition, the controller 12 of the fire vehicle 10 makes a request to the controller 21 of the fire extinguishing vehicle 20 on standby around the fire vehicle 10 to move to a safe place at a set time (e.g., 2 to 3 minutes) before the fire truck arrives, so as not to affect the entry of the fire truck. The fire extinguishing vehicle 20 on standby around the fire vehicle 10 can move to a safe place according to the request of the controller 12 of the fire vehicle 10. Here, the automatic driving controller 25 of the fire extinguishing vehicle 20 on standby performs automatic driving control to move its own vehicle 20 to a safe place.

[0112] Otherwise, the controller 21 of the standby fire-fighting vehicle 20 can receive the position of the fire truck from the fire station 70 in real time, and the automatic driving controller 25 of the fire-fighting vehicle 20 can perform automatic driving control within a set time (for example, 2 to 3 minutes) before the arrival of the fire truck to move its own vehicle 20 to a safe place.

[0113] When the fire truck arrives at the fire scene, the firefighters separate the fire water supply pipe 40 of the fire extinguishing vehicle 20 from the burning vehicle 10, connect the fire hose of the fire truck to the burning vehicle 10 to supply fire water, and supply the fire water stored in the water tank of the fire truck to the burning vehicle 10, thereby extinguishing the fire in the burning vehicle 10.

[0114] In various exemplary embodiments of the present disclosure, the fire-fighting vehicle 20 can move or drive in an automatic driving mode during part or all of the above-mentioned process (i.e., the process of the fire-fighting vehicle 20 moving to the position of the fire vehicle 10, the process of the fire-fighting vehicle 20 moving to the docking position with the fire vehicle 10, and the process of the fire-fighting vehicle 20 on standby after arriving at the position of the fire vehicle 10 moving to a safe position before the fire truck arrives).

[0115] Of course, if the automatic driving mode cannot be executed, the fire fighting vehicle 20 can be driven and moved in the manual mode in the state where the automatic driving mode is released according to the driver's judgment. The fire fighting vehicle 20 can also be moved or driven in the manual mode during part or all of the above process.

[0116] For example, the controller 12 of the fire-occurring vehicle 10 may transmit the internal temperature of the battery pack 1 detected by the temperature sensor 5 to the fire-extinguishing vehicle 20 through the communication device 13 .

[0117] Here, when the internal temperature of the battery pack 1 received through the communication device 22 is equal to or greater than a predetermined temperature (eg, 200° C.), the controller 21 of the fire extinguishing vehicle 20 releases the automatic driving mode by communicating with the automatic driving controller 25 .

[0118] Thereafter, the controller 21 of the fire extinguishing vehicle 20 guides the driver to move the fire extinguishing vehicle 20 to a safe place in the manual mode through the display 23, etc. When the internal temperature of the battery pack 1 of the fire vehicle 10 is equal to or greater than a predetermined temperature (e.g., 200° C.), it is determined that thermal runaway occurs in the battery pack 1 and it is difficult to extinguish the fire in the battery pack 1, and thus the fire extinguishing vehicle 20 is moved to a safe place in the manual mode.

[0119] Here, the damper 14 b and the flow control valve 15 in the fire vehicle 10 are closed to prevent the fire in the battery pack 1 from spreading.

[0120] Hereinafter, a structure in which the fire extinguishing vehicle 20 is docked with the fire vehicle 10 to supply fire-fighting water to the fire vehicle 10 in the fire extinguishing system according to various exemplary embodiments of the present disclosure will be described.

[0121] Figure 5 , Figure 6 and Figure 7 2 is a view exemplarily showing an example of docking of a fire extinguishing vehicle 20 with a fire ignition vehicle 10 in an exemplary embodiment of the present disclosure, Figure 8 is with Figure 6 and Figure 7 Compared to the view exemplarily showing in more detail the docking device of the fire extinguishing system according to various exemplary embodiments of the present disclosure, Fig. 9 and Fig.10is a view exemplarily illustrating an operation process of a docking device according to various exemplary embodiments of the present disclosure.

[0122] like Figures 6 to 8 As shown, the fire-fighting vehicle 20 includes a fire-fighting water supply pipe 40 that can be docked with the fire-fighting water inflow pipe 14 of the fire vehicle 10 . The fire-fighting water supply pipe 40 moves to a position where it can dock with the fire-fighting water inflow pipe 14 as the fire-fighting vehicle 20 travels.

[0123] Furthermore, the fire-fighting vehicle 20 further includes a height adjustment module 27 configured to adjust the height of the fire-fighting water supply pipe 40 to be consistent with the height (ie, the position in the vertical direction) of the fire-fighting water inflow pipe 14 .

[0124] The fire water supply pipe 40 includes a flexible hose 41 having a first end connected to the fire water tank 35 , a connector 43 provided at a second end of the flexible hose 41 , and an extension pipe 42 connected to the flexible hose 41 through the connector 43 to flow fire water.

[0125] The fire water tank 35 stores waste water generated and discharged from the fuel cell stack 31 as fire water supplied to the fire water inflow pipe 14, and is connected to the first end of the flexible hose 41 through the pump 36. The pump 36 extracts the fire water stored in the water tank 35 and sends the fire water to the flexible hose 41.

[0126] The connector 43 is detachably coupled to the second end of the flexible hose 41 and is connected to the body of the fire-fighting vehicle 20, thereby being supported to be movable in the vertical direction. Here, the connector 43 is connected to the body of the fire-fighting vehicle 20 through a stopper 38 and a motor 38a for moving the stopper 38.

[0127] The extension pipe 42 is configured to be able to extend and expand in the longitudinal direction and the axial direction, and includes a joint 42d connected to one end of the fire water inflow pipe 14. The extension pipe 42 can be set as a multi-tube structure with overlapping hard pipes, and can be horizontally expanded to the outside of the body of the fire extinguishing vehicle 20 through the water supply pipe opening 28 opened by the baffle 29 of the fire extinguishing vehicle 20 to extend (refer to Fig. 9 ).

[0128] Reference Fig. 9 When the extension pipe 42 is extended, the joint 42d of the extension pipe 42 can be connected to the fire water inflow pipe 14 of the fire vehicle 10. The water supply pipe opening 28 is provided on the body of the fire extinguishing vehicle 20, specifically, the water supply pipe opening 28 is provided on the outer body 48 of the fire extinguishing vehicle 20, so that the extension pipe 42 passing through the water supply pipe opening 28 is retracted to the outside of the fire extinguishing vehicle 20.

[0129] Reference Figure 8In the illustrated exemplary embodiment, the extension pipe 42 includes a first pipe 42a having a first end fixed to the connector 43 and a second pipe 42c inserted into the first pipe 42a to overlap with the first pipe 42a so as to be movable in the longitudinal direction and the axial direction.

[0130] The second pipe 42c includes a first end provided with a joint 42d and a second end provided with a protrusion 42e. When the second pipe 42c moves linearly in a direction to be withdrawn from the first pipe 42a, the protrusion 42e is caught by the joint 42b of the first pipe 42a, so that the second pipe 42c stops moving, and the joint 42d is connected to the end of the fire water inflow pipe 14. The joint 42d can be directly connected to the end of the fire water inflow pipe 14 by press fitting.

[0131] In addition, a pressure sensor 46 for measuring the pressure applied to the joint 42d is also provided on the extension pipe 42. The pressure sensor 46 can measure the pressure applied to the joint 42d when the joint 42d is connected to the fire water inflow pipe 14 by press fitting, and can be directly provided on the joint 42d. Whether the fire water inflow pipe 14 and the extension pipe 42 of the fire water supply pipe 40 are butted can be determined based on the pressure value measured by the pressure sensor 46.

[0132] The spring member 44 provided on the connector 43 applies pressure to the extension tube 42 in the extension direction in a compressed state. The spring member 44 includes a first end fixedly mounted on the connector 43 and a second end fixedly mounted on the extension tube 42.

[0133] The extension pipe 42 includes a bracket 42f, and the second end of the spring member 44 is connected to the bracket 42f. The bracket 42f is provided on the second pipe 42c which is retracted from the first pipe 42a to extend the extension pipe 42. When the joint 42d of the second pipe 42c contacts the baffle 29, the spring member 44 is pressed into a compressed state, thereby being supported to generate an elastic restoring force. When the baffle 29 opens the water supply pipe opening 28, the second pipe 42c is retracted from the first pipe 42a under the elastic restoring force of the spring member 44 (refer to Fig. 9 Here, the length of the extension pipe 42 extends from the joint 42d, and the joint 42d is connected to the end of the fire water inflow pipe 14 through the water supply pipe opening 28.

[0134] Although not shown in the figure, a structure matching with the joint 42d may be provided at the end of the fire water inflow pipe 14. For example, a groove structure engaging with the protruding structure of the joint 42d may be provided on the inner circumferential surface of the end of the fire water inflow pipe 14.

[0135] In addition, a bellows 45 may be provided on the connector 43 to cover the spring member 44 to protect the spring member 44. The bellows 45 is configured to be retractable and includes a first end coupled to the connector 43 and a second end coupled to the bracket 42f of the extension tube 42.

[0136] The baffle 29 is configured to open or close the water supply pipe opening 28 set on the body of the fire-fighting vehicle 20, and is connected to the motor 29a for moving the baffle 29 through the rack and pinion set 29b, and is raised and lowered by driving the motor 29a for moving the baffle 29 to open or close the water supply pipe opening 28.

[0137] The height (ie, the position in the vertical direction) of the fire water supply pipe 40 is adjusted by the height adjustment module 27 provided in the fire fighting vehicle 20. The height of the fire water supply pipe 40 is adjusted before the fire water supply pipe 40 is docked with the fire water inflow pipe 14.

[0138] The height adjustment module 27 includes a first magnet 27a mounted on the connector 43 of the fire water supply pipe 40 and a second magnet 27b mounted on the body of the fire fighting vehicle 20 and spaced apart from the first magnet 27a in the vertical direction. One of the first magnet 27a and the second magnet 27b is a permanent magnet, and the other is an electromagnet. When current is applied to the electromagnet, the electromagnet generates magnetic force to move the connector 43 of the fire water supply pipe 40 in the vertical direction.

[0139] Reference Figure 8 The first magnet 27a can be fixedly mounted on the upper end of the connector 43, and the second magnet 27b can be fixedly mounted on a mounting bracket 27c fixed on the body of the fire-fighting vehicle 20.

[0140] In an exemplary embodiment of the present disclosure, the first magnet 27a may be a permanent magnet, and the second magnet 27b may be an electromagnet. The current value applied to the electromagnet may be controlled by the controller 21 of the fire-fighting vehicle 20. The vertical movement amount of the connector 43 is determined by the current intensity applied to the electromagnet, and the movement direction of the connector 43 is determined by the current direction applied to the electromagnet. For example, when a positive (+) value current is applied to the second magnet 27b, an attractive force is generated between the first magnet 27a and the second magnet 27b, and therefore, the connector 43 of the fire water supply pipe 40 can be raised. In addition, when a negative (-) value current is applied to the second magnet 27b, a repulsive force is generated between the first magnet 27a and the second magnet 27b, and therefore, the connector 43 of the fire water supply pipe 40 can be lowered.

[0141] The current value applied to the second magnet 27b is determined based on the vertical movement amount of the fire water supply pipe 40 so as to position the fire water supply pipe 40 at the same height as the fire water inflow pipe 14. The vertical movement amount of the fire water supply pipe 40 may be determined by the controller 21 of the fire extinguishing vehicle 20. The controller 21 may be configured to determine the vertical movement amount of the fire water supply pipe 40 based on the height difference between the fire water inflow pipe 14 and the fire water supply pipe 40.

[0142] The horizontal movement of the connector 43 is restricted by the stopper 38 mounted on the body of the fire-fighting vehicle 20. The stopper 38, which serves as a locking device for the connector 43, is connected to the body of the fire-fighting vehicle 20 through a motor 38a for moving the stopper 38 to be mounted on the body of the fire-fighting vehicle 20, and is connected to the motor 38a for moving the stopper 38 through a rack gear set 38b. Therefore, by driving the motor 38a for moving the stopper 38, the stopper 38 can be linearly moved in a direction to separate from the connector 43. Fig.10 , the connector 43 separated from the stopper 38 can move not only in the vertical direction but also in the horizontal direction.

[0143] In addition, even before the connector 43 is separated from the stopper 38 (that is, even in a state where the connector 43 is coupled to the stopper 38), the connector 43 can be moved in the vertical direction. For this purpose, a guide groove 38c is provided in the stopper 38, and one end of the connector 43 is inserted into the guide groove 38c. The guide groove 38c is retracted into the upper end of the stopper 38 in the vertical direction.

[0144] The connector 43 moves linearly in the vertical direction under the magnetic force generated by the second magnet 27b, and does not move due to friction with the stopper 38 when no magnetic force is generated. To this end, the surface friction between the connector 43 and the guide groove 38c of the stopper 38 is set to be greater than the gravity value applied to the connector 43.

[0145] Furthermore, as an exemplary embodiment of the present disclosure, the connector 43 may be coupled to the stopper 38 to be positioned at the lowest position based on the height of the fire water inflow pipe 14 according to the vehicle type, and the fire water supply pipe 40 may be moved to the same height as the fire water inflow pipe 14 simply by raising the connector 43. In this case, before the fire water supply pipe 40 is moved under the action of the magnetic force, the connector 43 is located at the lowest position of the guide groove 38c of the stopper 38.

[0146] Reference Figure 4 and Figure 5The fire water inflow pipe 14 includes a first end (i.e., a water inlet) adjacent to an inflow pipe opening 14a provided on one side of the vehicle body of the fire vehicle 10, and a second end (i.e., a water outlet) connected to the battery box 2 of the battery pack 1 provided in the fire vehicle 10. The inflow pipe opening 14a is opened or closed by a baffle 14b provided on the side of the vehicle body of the fire vehicle 10.

[0147] The fire water inflow pipe 14 discharges the fire water supplied through the fire water supply pipe 40 to the inside of the battery box 2. The fire water supplied to the fire water inflow pipe 14 through the fire water supply pipe 40 can flow into the battery box 2 to fill the inside of the battery box 2.

[0148] The damper 14b of the fire vehicle 10 can open or close the inflow pipe opening 14a by an actuator including a motor and a gear rack set. Therefore, the damper 14b can open or close the inflow pipe opening 14a while being raised and lowered by the drive of the actuator. The operation of the damper 14b can be controlled by the controller 12 of the fire vehicle 10, and the controller 12 is configured to control the operation of the actuator so that when it is determined that a fire has occurred in the fire vehicle 10, the damper 14b opens the inflow pipe opening 14a. The damper 14b is controlled to open the inflow pipe opening 14a at the time point when the fire has occurred in the fire vehicle 10.

[0149] Hereinafter, a process of docking the fire extinguishing vehicle 20 with the fire starting vehicle 10 using the above-mentioned docking apparatus for a fire extinguishing system according to an exemplary embodiment of the present disclosure will be described.

[0150] Fig.11 is a flow chart illustrating a method of interfacing a fire extinguishing system according to various exemplary embodiments of the present disclosure.

[0151] Reference Fig.11 , when the fire extinguishing vehicle 20 travels at the request of the fire vehicle 10 and reaches the first position where the fire extinguishing vehicle docks with the fire vehicle 10 (S100), the automatic driving controller 25 of the fire extinguishing vehicle 20 is configured to determine the distance A between the fire water inflow pipe 14 and the fire water supply pipe 40. The automatic driving controller 25 compares the determined distance A with a predetermined first distance value a (S110), and when the determined distance A exceeds the first distance value a, adjusts the position of the fire extinguishing vehicle 20 (S112), and when the determined distance A is less than or equal to the first distance value a, performs more precise control to move the fire water supply pipe 40 to a second position where it can dock with the fire water inflow pipe 14.

[0152] Here, the first position is a position within a predetermined radius from the fire vehicle 10 , and the second position is a position where the extension pipe 42 of the fire water supply pipe 40 can be connected to the fire water inflow pipe 14 of the fire vehicle 10 due to the extension of the extension pipe 42 .

[0153] The distance A between the fire water inflow pipe 14 and the fire water supply pipe 40 is determined based on the position information of the fire water inflow pipe 14 and the position information of the fire water supply pipe 40. Here, the position information of the fire water inflow pipe 14 can be determined based on the position information and vehicle type information of the fire vehicle 10, and the position information of the fire water supply pipe 40 can be determined based on the position information and vehicle type information of the fire extinguishing vehicle 20. To this end, the automatic driving controller 25 of the fire extinguishing vehicle 20 can send a request to the fire vehicle 10 to obtain the vehicle type information and position information of the fire vehicle 10 when the fire extinguishing vehicle 20 arrives at the first position, and can receive the vehicle type information and position information of the fire vehicle 10 from the fire vehicle 10 (S120).

[0154] The positions of the fire water inflow pipe 14 and the fire water supply pipe 40 may represent the positions of the corresponding ends of the fire water inflow pipe 14 and the fire water supply pipe 40. More specifically, the ends of the fire water inflow pipe 14 and the fire water supply pipe 40 may represent the water inlet of the fire water inflow pipe 14 and the water outlet of the fire water supply pipe 40, and the positions of the water inlet of the fire water inflow pipe 14 and the water outlet of the fire water supply pipe 40 may refer to the radial center thereof.

[0155] In addition, the automatic driving controller 25 of the fire-fighting vehicle 20 can obtain image information of the fire-fighting water inflow pipe 14 provided in the fire-fighting vehicle 10 through a camera as a kind of automatic driving sensor 24 provided in the fire-fighting vehicle 20, and can more accurately detect the position of the end (i.e., the water inlet) of the fire-fighting water inflow pipe 14 connected to the fire-fighting water supply pipe 40 based on the obtained image information (S120). To this end, a designated mark can be set at the end of the fire-fighting water inflow pipe 14, which can be recognized by the camera of the fire-fighting vehicle 20. For example, a quick response (QR) code can be set at the end of the fire-fighting water inflow pipe 14, which can be recognized by the camera of the fire-fighting vehicle 20.

[0156] The automatic driving controller 25 can more accurately adjust the position of the fire water supply pipe 40 based on the position information of the fire water inflow pipe 14 acquired at the first position. The automatic driving controller 25 can identify the horizontal position and the vertical position of the fire water inflow pipe 14 based on the image information acquired through the camera and the vehicle type information and the position information of the fire vehicle 10. The position of the fire water inflow pipe 14 provided in the fire vehicle 10 is determined according to the vehicle type of the corresponding fire vehicle 10.

[0157] The automatic driving controller 25 is configured to perform automatic driving control of the operation of the steering device and the drive motor 26 of the fire-fighting vehicle 20 based on the vehicle type information and position information of the fire-causing vehicle 10 and the image information obtained by the camera, so that the fire-fighting vehicle 20 can move to the docking position between the fire water inflow pipe 14 and the fire water supply pipe 40.

[0158] The automatic driving controller 25 can adjust the horizontal position of the fire water supply pipe 40 by moving the fire extinguishing vehicle 20 so that it is consistent with the horizontal position of the fire water inflow pipe 14 (S130), and can also adjust the vertical position of the fire water supply pipe 40 by controlling the drive of the height adjustment module 27 so that it is consistent with the vertical position of the fire water inflow pipe 14 (S150).

[0159] The height adjustment module 27 is driven when the fire fighting vehicle 20 is stopped, and adjusts the vertical position of the fire fighting water supply pipe 40 by controlling the current applied to the electromagnet. The driving of the height adjustment module 27 can be controlled by the automatic driving controller 25 or the controller 21 of the fire fighting vehicle 20.

[0160] After adjusting the horizontal position of the fire water supply pipe 40 in operation S130, the automatic driving controller 25 is configured to determine whether the distance between the fire water supply pipe 40 and the fire water inflow pipe 14 satisfies the first condition (S140). Specifically, in operation S140, the automatic driving controller 25 is configured to determine whether the distance B between the fire water supply pipe 40 and the fire water inflow pipe 14 in the left and right directions is less than or equal to the predetermined second distance value b, and is configured to determine whether the distance C between the fire water supply pipe 40 and the fire water inflow pipe 14 in the forward and backward directions is greater than or equal to the predetermined third distance value c1 but less than or equal to the predetermined fourth distance value c2. When determining that the distance between the fire water supply pipe 40 and the fire water inflow pipe 14 does not satisfy the first condition, the automatic driving controller 25 readjusts the horizontal position of the fire water supply pipe 40 by adjusting the position of the fire extinguishing vehicle 20 (S130).

[0161] In addition, after adjusting the vertical position of the fire water supply pipe 40 in operation S150, the automatic driving controller 25 is configured to determine whether the vertical position (i.e., height) of the fire water supply pipe 40 is consistent with the height of the fire water inflow pipe 14 (S160). The automatic driving controller 25 performs operation S170 when it is determined that the height difference D between the fire water supply pipe 40 and the fire water inflow pipe 14 is less than or equal to the predetermined value d, and readjusts the height of the fire water supply pipe 40 when it is determined that the height difference D between the fire water supply pipe 40 and the fire water inflow pipe 14 exceeds the predetermined value d (S150).

[0162] In operation S170, the damper 29 of the fire-fighting vehicle 20 opens the water supply pipe opening 28, and the extension pipe 42 of the fire-fighting water supply pipe 40 extends toward the fire-fighting water inflow pipe 14 through the water supply pipe opening 28 by the spring member 44, and accordingly, the joint 42d of the extension pipe 42 is butted with the end of the fire-fighting water inflow pipe 14 by press-fitting. Here, the motor 29a for moving the damper 29 may be controlled by the controller 21 of the fire-fighting vehicle 20 or the automatic driving controller 25.

[0163] The automatic driving controller 25 is configured to determine whether the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is completed based on the pressure value E obtained from the pressure sensor 46 of the extension pipe 42 (S180). In operation S180, the automatic driving controller 25 is configured to determine that the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is completed when the pressure value E measured by the pressure sensor 46 is greater than or equal to the predetermined pressure value e, and is configured to determine that the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is not completed when the pressure value E measured by the pressure sensor 46 is less than the predetermined pressure value e.

[0164] From the time point when the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is completed, the current is no longer applied to the second magnet 27b. When the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is not completed, the automatic driving controller 25 can readjust the position of the fire extinguishing vehicle 20 and the position of the fire water supply pipe 40 (S182), and then the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 can be attempted again.

[0165] When the docking between the fire water inflow pipe 14 and the fire water supply pipe 40 is completed, the automatic driving controller 25 separates the stopper 38 from the connector 43 of the fire water supply pipe 40 by driving the motor 38a for moving the stopper 38 (S190). When the connector 43 is separated from the stopper 38, the locking (i.e., movement restriction) of the connector 43 and the stopper 38 is released, so that the connector 43 is in a state that can be retracted to the outside of the body of the fire extinguishing vehicle 20 through the water supply pipe opening 28 together with the flexible hose 41.

[0166] Thereafter, in order to ensure a safe distance of the fire extinguishing vehicle 20 , the automatic driving controller 25 moves the fire extinguishing vehicle 20 in a direction away from the fire occupancy vehicle 10 to increase the distance between the fire extinguishing vehicle 20 and the fire occupancy vehicle 10 in operation S200 .

[0167] although Figure 6 The flexible hose 41 is shown to have a short length, but the flexible hose 41 can actually be set to have a predetermined long length and can be accommodated in the body of the fire-fighting vehicle 20. Figure 7As shown, in the docking state where the extension pipe 42 of the fire extinguishing vehicle 20 is connected to the fire water inflow pipe 14 of the fire vehicle 10 through the joint 42d, when the fire extinguishing vehicle 20 moves, the flexible hose 42 can be unfolded to extend to the outside of the body of the fire extinguishing vehicle 20.

[0168] Figure 6 The two fire-fighting vehicles 20 are shown to be docked with the fire vehicle 10 at the same time. The two fire-fighting vehicles 20 can be docked with the fire vehicle 10 at the same time with the dampers 14b and 29 of the fire vehicle 10 and the fire-fighting vehicles 20 opened, so as to be configured to supply fire-fighting water to the fire vehicle 10.

[0169] Figure 7 The fire extinguishing vehicle 20 is shown as being in a docked state with the fire ignition vehicle 10 and the fire extinguishing vehicle 20 is moving in a direction away from the fire ignition vehicle 10 .

[0170] As shown in the figure, when the fire-fighting vehicle 20 is docked with the fire-causing vehicle 10, the extension pipe 42 of the fire-fighting vehicle 20 is connected to the fire water inflow pipe 14 of the fire-causing vehicle 10 through the joint 42d. In this state, the fire-fighting vehicle 20 can move in a direction away from the fire-causing vehicle 10 to ensure a safe distance.

[0171] Therefore, while ensuring a safe distance from the fire extinguishing vehicle 20, the fire water stored in the water tank 35 can be supplied to the fire water inflow pipe 14 of the fire vehicle 10 through the fire water supply pipe 40 by driving the pump 36 of the fire extinguishing vehicle 20 (S200).

[0172] Thereafter, when the fire truck arrives around the fire vehicle 10, the flexible hose 41 can be separated from the extension pipe 42 connected to the fire water inflow pipe 14 of the fire vehicle 10, and the fire hose of the fire truck can be connected to the extension pipe 42 by operating the connector 43 between the flexible hose 41 and the extension pipe 42 of the fire water supply pipe 40. Here, the fire water stored in the water tank of the fire truck is supplied to the inside of the fire vehicle 10 (the inside of the battery pack) through the extension pipe 42 and the fire water inflow pipe 14.

[0173] The flexible hose 41 may be configured to be detachably coupled with the connector 43 through a general quick-joint type connection member 41a. Therefore, by moving the fire-fighting vehicle 20 in a direction away from the fire vehicle 10 again, the connection member 41a may be separated from the connector 43.

[0174] The docking process between the above-mentioned fire water inflow pipe 14 and the fire water supply pipe 40 can be executed through the coordinated control between the controller 12 of the fire vehicle 10 and the automatic driving controller 25 of the fire extinguishing vehicle 20, or it can be executed through the coordinated control between the controller 12 of the fire vehicle 10 and the automatic driving controller 25 and controller 21 of the fire extinguishing vehicle 20.

[0175] In addition, the fire extinguishing system according to various exemplary embodiments of the present disclosure further includes a compensation system configured to provide financial compensation to a driver of a vehicle participating in the fire extinguishing.

[0176] Fig.12 is a block diagram illustrating a fire extinguishing system including a compensation system according to various exemplary embodiments of the present disclosure, and illustrates a server of a fire station 70 , a server of a vehicle manufacturer 50 , a controller of a fire vehicle 10 , and a controller of a fire extinguishing vehicle 20 .

[0177] When surrounding vehicles 20 located within a set radius distance from the fire vehicle 10 receive fire occurrence information, and the drivers of the surrounding vehicles 20 select and input fire extinguishing participation, the corresponding surrounding vehicles 20 can be selected as fire extinguishing vehicles 20. In this case, economic and financial compensation can be provided to the selected fire extinguishing vehicles 20.

[0178] The compensation system may be operated through cooperation between a service provider (ie, a vehicle manufacturer) 50 and an insurance company 60 , and includes a server of the service provider 50 and a server of the insurance company 60 .

[0179] The server of the service provider 50 and the server of the insurance company 60 are servers that are connected to each other through the Internet or other wired and wireless communication networks so as to be able to communicate with each other, and after participating in fire fighting, the compensation system provides compensation services with financial and economic benefits, such as coupons, cash (money) or vehicle insurance discounts, etc. to the drivers of the fire fighting vehicles 20 connected to these servers.

[0180] The driver of the vehicle 10 on fire pre-registers as a member of the service provider 50 so as to easily obtain fire-fighting assistance from other vehicles when a fire occurs. The driver registered as a member obtains support of fire-fighting services when a fire actually occurs in the vehicle 10 .

[0181] In various exemplary embodiments of the present disclosure, the service provider 50 may be a vehicle manufacturer 50 that manufactures the vehicle 10 that caught fire, and the insurance company 60 may be an insurance company that operates vehicle insurance purchased by a driver of the vehicle 10 that caught fire.

[0182] Reference Fig.12 The server of the fire station 70 receives the fire occurrence information from the controller of the fire vehicle 10, is configured to execute all the processes of dispatching the fire truck, and sends the location of the fire truck to the fire extinguishing vehicle 20 in real time until the fire truck arrives at the location of the fire vehicle 10.

[0183] Therefore, the fire extinguishing vehicle 20 can confirm the position of the fire truck and can be moved to a safe place from the fire vehicle 10 within a set time before the fire truck arrives at the fire scene. Here, in addition to the fire extinguishing vehicle 20 in a standby state, the fire extinguishing vehicle 20 connected to the fire vehicle 10 to supply fire water to the fire vehicle 10 can also be separated from the fire vehicle 10 and can be moved to a safe place.

[0184] In the elements of the compensation system, a server of a service provider (i.e., a vehicle manufacturer) 50 receives information indicating whether a fire has occurred and overall vehicle status information from a vehicle (i.e., a fire-occurring vehicle) 10 of a driver joining the service, and the service provider 50 is configured to determine the cause of the fire by analyzing the received vehicle status information.

[0185] In addition, the service provider 50 can also receive information related to the vehicle fire from the fire vehicle 10, such as whether the fire is extinguished, the time taken to extinguish the fire, and fire status information, and can use this information for big data analysis of future vehicle fires. The fire status information may include the internal temperature of the battery pack 1 detected by the temperature sensor 5, the concentration of gases such as carbon monoxide detected by the gas detector, etc.

[0186] In addition, the server of the service provider 50 can be configured to determine whether the fire extinguishing vehicle 20 participates in the fire extinguishing by receiving docking information from the fire extinguishing vehicle 20, and the fire extinguishing vehicle 20 sends the docking information to the server of the service provider 50 only when the fire extinguishing vehicle 20 actually docks with the fire vehicle 10 and supplies fire water to the fire vehicle.

[0187] Therefore, the service provider 50 can confirm whether the fire-fighting vehicle 20 actually participates in the fire-fighting based on the docking information of the corresponding fire-fighting vehicle 20 received through the server of the service provider 50, and the server of the service provider 50 can only send information such as the number of fire-fighting participations of the driver with prior consent to the server of the insurance company 60.

[0188] The service provider 50 can confirm whether the fire-fighting vehicle 20 participates in the fire-fighting, and can provide compensation services with points, coupons or cash (money) to the driver of the fire-fighting vehicle 20. The insurance company 60 can confirm the number of fire-fighting participations of each of the corresponding vehicles, and can provide compensation services to the corresponding drivers by giving vehicle insurance discounts corresponding to the number of fire-fighting times.

[0189] In addition, the server of the service provider 50 can also receive information such as the supply of fire water, whether the fire is extinguished, and the amount of gas backflow detected by the gas detector installed in the fire extinguishing vehicle 20 based on the signal from the water level sensor 35a in the water tank 35 of the fire extinguishing vehicle 20, and the service provider 50 can use this information for big data analysis of future vehicle fires.
