The present application claims priority to Korean Patent Application No. 10-2022-0173380, filed Dec. 13, 2022, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a cooperative fire extinguishing system for a vehicle, and more particularly, to a fire extinguishing system that can rapidly and effectively extinguish a fire occurring in an eco-friendly vehicle through cooperation of vehicles.
In general, because not only many heat sources exist, but also various electric wires are complexly provided in vehicles, a possibility of a fire always exists in vehicles. A fire may occur at tires, etc. that generate heat due to friction in addition to electric parts in a vehicle.
Recently, as eco-friendly vehicles such as an electric vehicle or a fuel cell vehicle are becoming popularized, the possibility of a fire at a battery or high-voltage electric wires in such vehicles due to external shock, an internal short circuit, or the like is increasing.
Eco-friendly vehicles (xEVs) all have something in common in that they are all driven by driving a motor using power stored in a battery, and all thereof may be considered as electric vehicles in a broad sense. Such electric vehicles are provided with a high-voltage battery pack that supplies power to a motor and the high-voltage battery pack supplies power to the power electronic system including a motor while being repeatedly charged and discharged while the vehicles are driven.
The battery pack of electric vehicles generally includes a battery case, a battery module disposed in the battery case, a Battery Management System (BMS) that detects the voltage, current, temperature, etc. of cells constituting the battery module and controls operation of the cells, etc.
Furthermore, the battery pack includes a configuration that prevents a fire by cutting a fuse or disconnecting a relay connected to an inverter when an internal short circuit is generated or an overcurrent flows in the battery pack.
However, a fire may occur at the battery pack or electric wires in an electric vehicle due to various reasons such a collision and malfunction of parts while the electric vehicle is driven. Unless such a fire in a vehicle is extinguished well, the fire may cause total destruction of the vehicle, which may result in a large physical and human loss.
A fire of a battery may rapidly spread due to structures and substances inside and outside the battery and public transportation vehicles such as a bus carries many passengers, so it is necessary to rapidly cope with a fire for the safety of passengers, and when the first response fails, it may result in a catastrophe.
Nevertheless, preparing and using a fire extinguisher is the best present method that can cope with a fire in a vehicle. In the instant case, similarly, when a driver does not use a fire extinguisher at the right time, first extinguishing fails, such that the fire may spread throughout the vehicle and the possibility of human costs increases. Even though a driver or a passenger rapidly recognizes a fire in a vehicle, it is difficult to extinguish the fire using only a small fire extinguisher prepared in the vehicle.
When there is a fire hydrant around a vehicle or there is a fire truck around a fire site, it is possible to extinguish the fire by sprinkling fire extinguishing water on the vehicle, but if not so, it is difficult to extinguish the fire at the earl stage.
Recently, as more eco-friendly vehicles (xEV) that are provided with a high-voltage battery, have a high possibility of a fire at a battery or a high electric system, and make first extinguishing difficult are used, there is a high demand for a method that can more rapidly and effective extinguish a fire at the early stage when a fire occurs while driving.

The present disclosure relates to a fire extinguishing system that can extinguish a fire occurring in a vehicle. The present disclosure provides a cooperative fire extinguishing system that can rapidly and effectively extinguish a fire occurring in a vehicle at the early stage through cooperation of vehicles.
The fire extinguishing system according to an exemplary embodiment of the present disclosure may be a system for extinguishing a fire occurring in eco-friendly vehicles. The fire extinguishing system according to an exemplary embodiment of the present disclosure is configured so that one of surrounding vehicles 20 is docked to a vehicle on fire 10 and then the system can extinguish a fire in the vehicle on fire using fire extinguishing water which is supplied from the docked surrounding vehicle. In the present configuration, a plurality of vehicles can extinguish the fire in the vehicle on fire in cooperation.
The vehicle on fire 10 may be an eco-friendly vehicle, for example, an electric vehicle or a fuel cell vehicle provided 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 a vehicle fire in the instant case may be a fire occurring at a battery.
The vehicle 20 that can participate in fire extinguishment in an exemplary embodiment of the present disclosure is a vehicle which may be docked to a vehicle on fire 10 and can supply fire extinguishing water stored in a tank 35. The vehicle 20 that can participate in fire extinguishment in an exemplary embodiment of the present disclosure is a vehicle that can communicate with a vehicle on fire or an external system and can extinguish a fire in cooperation while transmitting and receiving necessary information through communication.
For example, the vehicle 20 that can participate in fire extinguishment in an exemplary embodiment of the present disclosure is a vehicle may be a fuel cell vehicle that can store discharge water produced in and discharged from a fuel cell stack (reference number “35” in
The fire extinguishing system according to an exemplary embodiment of the present disclosure, which is mounted in a vehicle on fire 10, includes: a fire detector 11 provided in the vehicle 10 to detect a fire occurring in the vehicle: a controller 12 mounted in the vehicle 10 and performing a control process for extinguishing a fire by entering a fire extinguishment mode when determining that a fire has occurred in the vehicle through the fire detector 11: a communication device 13 mounted in the vehicle 10 to communicate with external systems such as a surrounding vehicle 20, the server of a fire station, etc.
In an exemplary embodiment of the present disclosure, the first detector may be a temperature sensor which is configured to detect a temperature (reference numeral “5” in
The controller 12 can determine that a fire has occurred when the temperature detected from a signal received from the temperature sensor is a predetermined temperature or higher than the predetermined temperature, the concentration of carbon monoxide detected from a signal received from the gas detector is a set concentration or more than the set concentration, or an electrical signal is input from the fire detection line.
In an exemplary embodiment of the present disclosure, when a fire occurs in the corresponding vehicle (hereafter, referred to as a “subject vehicle”), the controller 12 is configured to perform a control process set for extinguishing a fire to be described below; that is, is configured to perform control for warning of the fire occurrence situation to the inside and outside the vehicle or warning of fire occurrence to the outside by transmitting fire occurrence information through the communication device 13 and for requesting fire extinguishment.
To the present end, the fire extinguishing system of the present disclosure may further include a warning device that warns of fire occurrence by operating in accordance with a control signal that the controller of the vehicle on fire 10 outputs after determining that a fire has occurred. The warning device may be a warning light or an alarm provided in a vehicle.
The communication device 13 of the vehicle on fire 10 is provided to communicate with external systems such as surrounding vehicles 20, the server of a fire station located outside the vehicle, etc. In an exemplary embodiment of the present disclosure, as the automotive communication device, well-known communication devices may be used without limitation in communication type as long as they enable a corresponding vehicle to communicate with the outside of the vehicle through wireless communication.
The fire extinguishing system according to an exemplary embodiment of the present disclosure further includes a fire extinguishing vehicle 20 that can supply fire extinguishing water, includes a communication device 22, and can communicate with the outside through the communication device 22. The fire extinguishing vehicle 20 is a vehicle that is, as described above, docked to the vehicle on fire 10 and then supplies fire extinguishing water, extinguishing a fire.
Referring to
The fire extinguishing vehicle 20 in an exemplary embodiment of the present disclosure is provided with a tank 35 for storing discharge water which is produced and discharged from the fuel cell stack 31, and a pump 36 that draws the discharge water stored in the tank 35 and sends the discharge water through a supply pipe 37.
In an exemplary embodiment of the present disclosure, when the fire extinguishing vehicle 20 is a fuel cell vehicle that can autonomously drive, the first extinguishing vehicle 20, as shown in
In an exemplary embodiment of the present disclosure, the fire extinguishing vehicle 20 is located within a set distance around the vehicle on fire 10, receives fire occurrence information transmitted from the vehicle on fire 10 through the communication device 22, and then moves to the vehicle on fire 10, participating in fire extinguishment.
The communication device 22 of the surrounding vehicle 20 that can participate in fire extinguishment is not different from the communication device of the vehicle on fire 10 in an exemplary embodiment of the present disclosure, and may be a wireless communication device which is mounted in the surrounding vehicle 20 to wirelessly communicate with an external system such as the vehicle on fire 10 and severs (servers indicated by reference numerals “40”, “50”, and “60” in
It is expected that a connected car that communicates in real time with another vehicle, traffic and communication infrastructures, a pedestrian terminal, etc. will be popularized together with an autonomous vehicle, and the fire extinguishing system according to an exemplary embodiment of the present disclosure may be configured as a system that includes and utilizes such a connected art and autonomous vehicle.
In an exemplary embodiment of the present disclosure, when determining that a fire has occurred in the vehicle on fire 10 through the fire detector 11, the controller 12 of the vehicle on fire 10 transmits a fire occurrence signal, which warns of occurrence of a fire, and a fire extinguishment request signal, and fire occurrence information including the subject vehicle location, etc. through the communication device 13.
The controller 12 and the communication device 13 of the vehicle on fire 10 may be set in the instant case to transmit the fire occurrence information to all surrounding vehicles 20 located within a set radius distance (e.g., 5 km) from the subject vehicle.
Furthermore, the controller 12 and the communication device 13 of the vehicle on fire 10 may be set to transmit fire occurrence information to a closest fire station 40 from the subject vehicle location, and in the instant case, can transmit fire occurrence information including subject vehicle location information and driver information together with the fire occurrence signal that warns of occurrence of a fire. Accordingly, the fire station 40 enables a fire truck to turn out to the vehicle on fire 10 after receiving the fire occurrence information.
When the fire station 40 receives the fire occurrence information, the fire station 40 can attempt to speak to the driver over the telephone using the driver information of the vehicle on fire 10, and can send a fire truck after confirming that a fire has actually occurred through the telephone call with the driver.
In an exemplary embodiment of the present disclosure, the controller 12 of the vehicle on fire 10 checks the location of the fire station 40 and the radius distance to the fire house 40 from the current location and is configured to determine a travel time that a fire truck takes to reach the current location, using navigation information including map information and real-time traffic information.
Furthermore, the controller 12 of the vehicle on fire 10 may be set not to transmit fire occurrence information to surrounding vehicles 20 when the radius distance to the fire station 40 from the current location is within the set radius distance and the travel time that a fire truck takes to reach the current location is a set time (e.g., 15 minutes) or less.
In the instant case, a travel time to which real-time traffic information is applied may be used. The reason of not transmitting fire occurrence information to surrounding vehicles 20 when a travel time is a set time or less, as described above, is because the fire may be extinguished at the early stage by even only turning-out of a fire truck.
When the fire station 40 is located out of the set radius distance or the travel time of a fire truck exceeds the set time, the controller 12 of the vehicle on fire 10 requests fire extinguishment by transmitting fire occurrence information to surrounding vehicles 20 located within the set radius distance.
Meanwhile, in surrounding vehicles 20 that can participate in fire extinguishment, the location information of the vehicle on fire 10 is displayed on an automotive display 23, and travel times that are taken to reach the vehicle on fire 10 from current locations are determined and displayed as times to which a real-time traffic situation is applied.
Furthermore, information for asking for whether to participate in fire extinguishment and a popup window for a driver to select and input whether to participate in fire extinguishment may also be displayed on the display 23. The display 23 may be a display which is provided in a vehicle and displays navigation information including map information and location information by operating with a navigation device.
The display 23 may be also a display connected to a separate input device enabling a driver to select and input whether to participate in fire extinguishment or a touch screen type display including a configuration integrated with the input device.
As described above, a popup window through which it is possible to select and input whether to participate in fire extinguishment is displayed on the displays 23 of surrounding vehicles 20 located around the vehicle on fire 10 and receiving fire occurrence information from the vehicle on fire, and a driver can select and input whether to participate in fire extinguishment through the popup window displayed on the displays 23.
A participation selection button may be displayed in the popup window and a driver can participate in fire extinguishment by pressing the participation selection button displayed in the popup window.
When a driver selects and inputs participation in fire extinguishment in a surrounding vehicle 20 receiving the fire occurrence information, a fire extinguishment participation signal showing the intention of participating in fire extinguishment may be transmitted to the vehicle on fire 10 through the communication device 22.
The controller 12 of the vehicle on fire 10 is configured to determine the vehicle that transmitted the fire extinguishment participation signal as a fire extinguishing vehicle 20 based on the fire extinguishment participation signal received through the communication device 13. The controller 12 of the vehicle on fire 10 transmits a fire extinguishment request signal to the fire extinguishing vehicle 20 through the communication device 13.
A water level sensor 35a may be provided at the tank 35 that stores fire extinguishing water in the surrounding vehicle 20 that can participate in fire extinguishment, that is, the tank 35 in which discharge water is stored in a fuel cell vehicle.
The controller 21 of the surrounding vehicle 20 obtains current water level information of the discharge water in the tank 35 from a signal from the water level sensor 35a, and allows for selecting and inputting participation in fire extinguishment only when the obtained current water level of the discharge water in the tank 35 is a predetermined water level or more than predetermined water level.
To the present end, the controller 21 of the surrounding vehicle 20 can activate a participation selection button in the popup window displayed on the display 23 only when the current water level of the discharge water in the tank 35 is a predetermined water level or more than predetermined water level.
Furthermore, in an exemplary embodiment of the present disclosure, the controller 12 of the vehicle on fire 10 may be set to determine only a setting number of vehicles of a plurality of surrounding vehicles 20, which transmitted a fire extinguishment participation signal, as fire extinguishing vehicles in order of arrival, and can transmit a fire extinguishment request signal only to the setting number of fire extinguishing vehicles.
When fire extinguishing vehicles are selected and the number of selected fire extinguishing vehicles reaches the setting number, the vehicle on fire 10 transmits a signal showing that it is impossible to participate in fire extinguishment to the other surrounding vehicles 20 that were not determined as fire extinguishing vehicles.
The reason of limiting the number of fire extinguishing vehicles 20 to the setting number in an exemplary embodiment of the present disclosure is for preventing traffic congestion due to several vehicles that participate in fire extinguishment.
In an exemplary embodiment of the present disclosure, the controller 12 of the vehicle on fire 10 may be configured to adjust the setting number in accordance with real-time traffic situation and road situation. For example, the controller 12 of the vehicle on fire 10 can also receive and use navigation information (information which is provided from a navigation device) and can determine the setting number based on the average speed information of vehicles on surrounding roads of the navigation information.
A setting number may be set in advance for each of divided sections of the vehicle average speed, and a corresponding setting number may be determined from the vehicle average speed on surrounding roads and may be used to limit the number of fire extinguishing vehicles when a fire actually occurs. The smaller the vehicle average speed in sections, the smaller value the setting number may be set as by the controller 12.
In an exemplary embodiment of the present disclosure, when a surrounding vehicle 20 is finally set as a fire extinguishing vehicle by a driver selecting and inputting participation in fire extinguishment, autonomous driving control may be performed by an autonomous driving controller 25 so that the vehicle moves through autonomous driving to the location of a vehicle on fire 10.
When the fire extinguishing vehicle 20 reaches the location of the vehicle on fire 10, docking in which fire extinguishing water passages of both vehicles are connected is performed so that fire extinguishing water may be supplied from the fire extinguishing vehicle 20 to the vehicle on fire 10.
When a plurality of fire extinguishing vehicles 20 reaches the location of the vehicle on fire 10, the fire extinguishing vehicle 20 that has reached first is docked to be able to supply fire extinguishing water to the vehicle on fire 10, and the other fire extinguishing vehicles 20 that reached the location of the vehicle on fire 10 are controlled to stand by in an autonomous state around the vehicle on fire 10.
In an exemplary embodiment of the present disclosure, a first, as described above, may be a batter fire, in detail, a fire occurring in a battery pack.
In an exemplary embodiment of the present disclosure, the battery pack 1 may include a battery case 2 and a battery module 3 disposed in the battery case 2. The battery module disposed in the battery case 2 includes a plurality of battery cells.
In an exemplary embodiment of the present disclosure, the battery case 2 includes a structure in the internal space which may be filled with fire extinguishing water, and to the present end, the internal space of the battery case 2 may be sealed with the battery module 3 therein.
That is, the battery case 2 includes a structure that surrounds and seals the battery module 3 including battery cells, so that the internal space of the battery case 2 may be filled with fire extinguishing water.
An injection pipe 14 through which fire extinguishing water is injected is connected to the battery case 1 and fire extinguishing water which is supplied from a docked fire extinguishing vehicle 20 is supplied into the internal space of the battery case 2 through the injection pipe 14, whereby a fire occurring at the battery module 3 is extinguished.
As described above, in an exemplary embodiment of the present disclosure, it is possible to extinguish a fire occurring in the internal space of the battery case 2 surrounding the battery module 3, and it is possible to extinguish a fire in the manner of filling the internal space of the battery case 2 with fire extinguishing water by supplying fire extinguishing water. The fire extinguishing water supplied in the internal space of the battery case 2 maintains the battery cells in a cooled state, preventing re-firing or thermal runway at the battery cells.
As shown in
Accordingly, the controller 12 of a vehicle on fire 10 is configured to determine a battery pack 1 with a fire based on a signal from a fire detector (which is indicated by reference numeral “11” in
Next, when fire extinguishing water is supplied through the injection pipe 14 from the first extinguishing vehicle 20 docked to the vehicle on fire 10, the fire extinguishing water may be injected to fill the internal space of the battery case 2 through the nozzle 4 in the battery pack 1 with a fire.
Reference numeral “5” indicates a temperature sensor in
Meanwhile, in an exemplary embodiment of the present disclosure, surrounding vehicles 20 wirelessly receive fire occurrence information transmitted from a vehicle on fire 10, and fire extinguishing vehicles 20 selected from the surrounding vehicles receiving the fire occurrence information are moved to the location of the vehicle on fire 10 and participate in fire extinguishment.
In the instant case, a plurality of fire extinguishing vehicles 20 can participate in fire extinguishment while transmitting and receiving necessary information by communicating with the vehicle on fire 10, and the plurality of fire extinguishing vehicles 20 arriving for in fire extinguishment can sequentially dock to the vehicle on fire 20 and can supply fire extinguishing water.
That is, the first arriving fire extinguishing vehicle 20 docks to the vehicle on fire 10 and supplies fire extinguishing water, and then when the stored fire extinguishing water is fully supplied, the fire extinguishing vehicle 20 stops operation of the pump 36 and then may be automatically separated from the vehicle on fire. Thereafter, the next fire extinguishing vehicle 20 docks to the vehicle on fire 10 and then supplies fire extinguishing water.
In the instant case, the order of docking to the vehicle on fire 10 and supplying fire extinguishing water may be determined as the order of reaching the location of the vehicle on fire 10, and fire extinguishing vehicles 20 dock to the vehicle on fire 10 and then supply fire extinguishing water in order of arrival, extinguishing the fire.
Furthermore, the controller 12 of the vehicle on fire 10 wirelessly requests fire extinguishing vehicles 20 standing by around the vehicle on fire to move to a safe place not to interfere with entry of a fire truck through the controllers 12 of the fire extinguishing vehicles 20 until a setting time (e.g., 2˜3 minutes) before the fire truck arrives, so that the fire extinguishing vehicles 20 standing by around the vehicle on fire 10 can move to a safe place in accordance with the request from the vehicle on fire 10. In the instant case, the autonomous driving controllers 25 of the fire extinguishing vehicles 20 standing by perform autonomous driving control to move subject vehicles to a safe place.
Alternatively, the controllers 21 of the fire extinguishing vehicles 20 standing by can receive in real time the location of a fire truck that has turned out from a fire station 40, and similarly, the autonomous driving controllers 25 of the fire extinguishing vehicles 20 perform autonomous driving control to move subject vehicles to a safe place until a setting time (e.g., 2˜3 minutes) before the fire truck arrives.
When a fire truck reaches the site, a firefighter separates the supply pipe 37 of a fire extinguishing vehicle 20 from the vehicle on fire 10 and connects a fire hose of the fire truck to be able to supply fire extinguishing water to the vehicle on fire 10, whereby fire extinguishing water stored in the tank of the fire truck is supplied to the vehicle on fire 10 and extinguishes the fire.
In an exemplary embodiment of the present disclosure, a fire extinguishing vehicle 20 may be moved in an autonomous driving mode during some or the entire of the processes described above such as the process in which a fire extinguishing vehicle 20 is moved to the location of the vehicle on fire 10, the process of moving to a docking position to dock to the vehicle on fire 10, the process of docking to the vehicle on fire, and the process in which the fire extinguishing vehicle stands by after reaching the location of the vehicle on fire 10 and then moves to a safety place right before a fire truck arrives.
Of course, when an autonomous driving mode is impossible, a fire extinguishing vehicle 20 may be driven and moved in a manual mode with the autonomous driving mode inactivated in accordance with determination of a driver. The present process may also be applied to some or the entire of the processes for fire extinguishment according to an exemplary embodiment of the present disclosure.
For example, the controller 12 of a vehicle on fire 10 can transmit information related to an internal temperature of a battery pack 1 detected by the temperature sensor 5 to a fire extinguishing vehicle 20 through the communication device 13.
In the instant case, the controller 21 of the fire extinguishing vehicle 20 inactivates the autonomous driving mode by communicating with the autonomous driving controller 25 when the internal temperature of the battery pack 1 received through the communication device 22 is a setting temperature (e.g., 200° C.) or more than the setting temperature.
Next, the driver of the fire extinguishing vehicle 20 is guided through the display 23, etc. to move the vehicle to a safe place in a manual mode. As described above, when the internal temperature of the battery pack 1 in the vehicle on fire is a setting temperature, for example, 200° C. or more that setting temperature, it means that thermal runway has occurred in the battery pack, so it is impossible to extinguish a fire of the battery pack. Accordingly, the fire extinguishing vehicle 20 is guided to move a safe place in a manual mode.
In the instant case, a flap 14b and the flow control valve 15 are closed in the vehicle on fire 10, preventing spread of the fire of the battery pack 1.

The extension pipe 37b may be a pipe including a multi-stage structure of overlapping hard pipes and can horizontally stretch out of the vehicle body through the opening 28 of the vehicle body when the flap 29 of the fire extinguishing vehicle 20 is opened. The horizontally stretching extension pipe 37b is connected to the injection pipe 14 of the vehicle on fire 10 through the connector 14c to supply fire extinguishing water.
The connecting member 37c is detachably provided inside the vehicle body of the fire extinguishing vehicle 20, and to the present end, the connecting member 37c is coupled to the internal surface of the vehicle body by a locking device including an actuator.
The locking device is unlocked by the controller 21 or the autonomous driving controller 25 of the fire extinguishing vehicle 20, and when the locking device is unlocked, the connecting member 37c may be detached and separated from the internal surface of the vehicle body of the fire extinguishing vehicle 20.
When the connecting member 37c is detached and separated from the internal surface of the vehicle body, the flexible hose 37a connected to the outlet of the pump 36 may be drawn out to be long from the vehicle through the opening 28 together with the connecting member 37c.
As shown in the figure, when a fire extinguishing vehicle 20 is docked to a vehicle on fire 10, the extension pipe 37b of the fire extinguishing vehicle 20 is connected to the injection pipe 14 of the vehicle on fire 10 through the connector 14c, and in the instant state, the fire extinguishing vehicle 20 may be moved away from the vehicle on fire 10 to secure a safety distance.
In the present process, the connecting member 37c coupled to the internal surface of the vehicle body of the fire extinguishing vehicle 20 is separated and the flexible hose 37a of the supply pipe 37 of the fire extinguishing vehicle 20 may be stretched and extended out of the fire extinguishing vehicle 20 through the opening 28.
Accordingly, the fire extinguishing vehicle 20 may be moved away from the vehicle on fire 10 and fire extinguishing water may be supplied to the vehicle on fire 10 through the supply pipe 37 from the fire extinguishing vehicle 20 with a safety distance secured.
When a fire truck arrives, the flexible hose 37a is separated from the extension pipe 37b connected to the injection pipe 14 of the vehicle on fire 10 by manipulating the connecting member 37c between the flexible hose 37a and the extension pipe 37b and a fire hose of the fire truck is connected to the extension pipe 37b so that fire extinguishing water in the tank of the fire truck is supplied into the vehicle on fire 10 (into a battery pack) through the extension pipe 37b and the injection pipe 14.
