Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, specifically to the field of vehicle warning and control technology, and specifically provides a detachable vehicle warning and interlocking device, a window breaking system, and a control method. Background Technology

[0002] When a new energy vehicle's power battery experiences an internal short circuit, overcharge, external heating, or mechanical damage, it may go through stages such as gas production, pressure release, significant temperature rise, smoke, and fire. Using information such as electrolyte vapor, hydrogen, carbon monoxide, carbon dioxide, particulate matter, and temperature can potentially provide early warning before a visible flame appears.

[0003] Existing vehicle window breaking devices include handheld safety hammers, fixed spring strikers, electromagnetic strikers, pneumatic or pyrotechnic window breakers, and there are automatic triggering schemes based on water immersion, collision, temperature or smoke. However, existing escape systems are generally simple combinations of sensors and vehicle window breakers. There are two ways to set up these sensors: the first is to permanently fix them near the window, which causes the gas in the early stages of battery thermal runaway to reach the sensor location later, reducing the warning effect; the second is to use movable sensors, which can easily cause danger when the device is held in the hand, placed on the seat, becomes loose, is installed on laminated glass, or when the vehicle is traveling at high speed.

[0004] Therefore, there is a need in the field for a detachable vehicle warning and interlocking device, window breaking system, and control scheme that can be detachably installed on the vehicle window, can be used in a free monitoring position, and can only enter the window breaking standby state after both mechanical installation and hazardous conditions have been verified, in order to solve the above problems. Summary of the Invention

[0005] Based on this, the present invention proposes a detachable vehicle warning and interlocking device, a window breaking system and a control method, which solves the technical problem that existing escape devices are simply a combination of sensors and vehicle window breaking devices, which cannot simultaneously ensure the monitoring effect and the escape effect, or even the warning effect is too low or there is a potential danger.

[0006] According to a first aspect of the present invention, a detachable vehicle warning and interlocking device is provided, comprising a housing, a control component, a sensing component, and a window-breaking execution component disposed within the housing: The housing is detachably mounted on the vehicle glass via a glass attachment assembly. The glass attachment assembly includes an adsorption unit and a status detection unit. The status detection unit is used to detect the installation status between the housing and the vehicle glass and output it to the control component. The sensing component is disposed on the housing, and the sensing component is used to acquire detection data in the early stage of vehicle thermal runaway and send it to the control component; The window-breaking execution component is disposed on the housing, and the window-breaking execution component performs the window-breaking operation according to the release permission of the control component; The control component is connected to the glass attachment component, the sensing component, and the window breaking execution component via signal connection. When the housing is installed on the vehicle glass, and the data acquired by the glass attachment component and the sensing component meets the preset confirmation conditions, the control component outputs a release permission to the window breaking execution component. When the device is in a free monitoring state, the control component controls the sensing component to maintain the detection state, while the device alarm function is on standby, and the window breaking execution component is prohibited from releasing.

[0007] According to an embodiment of the present invention, an adsorption cavity is provided between the vehicle window glass and the adsorption unit. The adsorption unit forms a negative pressure after compression. The state detection unit is connected to the adsorption cavity. The state detection unit determines the installation state of the device based on the pressure state of the adsorption cavity. The installation state is either a free monitoring state or a glass installation state.

[0008] According to an embodiment of the present invention, the glass attachment assembly further includes a glass reading unit. When the state detection unit determines that the installation state of the device is a glass installation state, the glass reading unit reads the glass identification tag, obtains the identification information corresponding to the glass, and outputs it to the control component.

[0009] According to an embodiment of the present invention, the sensing component includes a plurality of internal sensing units, which are respectively disposed in different types of sensing channels. The internal sensing units are used to acquire different types of detection values ​​and output them to the control component.

[0010] According to an embodiment of the present invention, the window-breaking execution component includes an energy storage component, a locking component, a releasing component, a firing pin, and a mechanical safety component. When the device is installed in a free monitoring state, the mechanical safety component prevents the firing pin from moving out of the housing.

[0011] According to an embodiment of the present invention, the control component includes a processing unit and an alarm unit, wherein the processing unit forms hazard evidence based on the increment, rate of change, duration, and sensor reliability of the detection values ​​output by each internal sensing unit relative to an individual environmental baseline; When the dangerous evidence meets the first evidence condition, an early warning operation is performed. The early warning operation is as follows: the alarm unit is controlled to output early alarm information, and the window breaking execution component is prohibited from being released. When the dangerous evidence meets the second evidence condition, a danger confirmation operation is performed. The danger confirmation operation is as follows: the alarm unit is controlled to output a danger alarm message and the window breaking execution component is prohibited from being released. When the dangerous evidence meets the third evidence condition, a release permission is output to the window breaking execution component.

[0012] According to a second aspect of the present invention, a detachable vehicle warning and interlocking window-breaking system is provided, the system comprising the detachable vehicle warning and interlocking device as described in any one of the preceding claims and a remote sensing device: The detachable vehicle warning and interlocking device is installed on the target window of the vehicle; The remote sensing device is installed in the vehicle's power battery pack, exhaust channel, or passenger compartment floor, and is communicatively connected to the detachable vehicle warning and interlocking device. The remote sensing device is used to detect early-stage thermal runaway characteristic parameters of the vehicle and send the early-stage thermal runaway characteristic parameters and remote sensing data to the detachable vehicle warning and interlocking device, so that the detachable vehicle warning and interlocking device can determine whether the early-stage thermal runaway characteristic parameters and remote sensing data sent by the remote sensing device constitute dangerous evidence.

[0013] According to an embodiment of the present invention, the system further includes: The system communicates with the vehicle via the vehicle interface terminal. The vehicle interface terminal is used to acquire vehicle data, which includes at least reliable vehicle speed information, door lock status information, window position information, collision information, and high voltage power-off information. When the control component of the detachable vehicle warning and interlocking device performs a confirmed danger operation, the system controls the vehicle system to unlock the window and lower the target window. Based on the vehicle data obtained from the vehicle interface, determine whether all the target windows have been lowered within a preset time: With all the target vehicle windows lowered, a request to cancel window breaking is sent to the detachable vehicle warning and interlocking device; Alternatively, if the target vehicle window is not fully lowered, the vehicle system is in an authorized state, and there are people inside the vehicle, or if there is a manually triggered window-breaking command in the vehicle data obtained from the vehicle interface, a window-breaking execution command is output to the detachable vehicle warning and interlocking device so that the window-breaking execution component of the detachable vehicle warning and interlocking device performs the window-breaking operation.

[0014] According to a third aspect of the present invention, a detachable vehicle warning and interlocking window-breaking control method is provided, applied to the detachable vehicle warning and interlocking window-breaking system described in any one of the preceding claims, characterized in that the method includes the following steps: The sensing components of the detachable vehicle warning and interlocking device acquire detection data in the early stages of vehicle thermal runaway and send it to the control components of the detachable vehicle warning and interlocking device. The remote sensing device of the detachable vehicle warning and interlocking window breaking system acquires the early characteristic parameters of vehicle thermal runaway and remote sensing data and sends them to the detachable vehicle warning and interlocking device. The remote sensing data includes at least the timestamp of the early characteristic parameters of vehicle thermal runaway, the health status of the remote sensing device, and authentication information. The glass attachment assembly of the detachable vehicle warning and interlocking device acquires the installation status of the housing and the target window and outputs it to the control assembly; When the installation status is glass installation status, the glass reading unit reads the glass identification tag, obtains the identification information corresponding to the glass, and outputs it to the control component; The control component forms hazard evidence based on the increment, rate of change, duration, and sensor reliability of the detection values ​​output by the internal sensing units of each sensing component and each remote sensing device relative to the individual environmental baseline. When the hazard evidence meets the first evidence condition, a warning verification operation is performed, and when the hazard evidence meets the second evidence condition, a hazard confirmation operation is performed. The hazard confirmation operation includes outputting alarm information to the alarm unit and outputting release permission to the window breaking execution component of the detachable vehicle warning and interlocking device when the hazard evidence meets the third evidence condition. The first evidentiary condition is that any of the detection values ​​of the sensing component shows an anomaly in its increment, rate of change, or duration relative to the environmental baseline; The second evidentiary condition is that the increment, rate of change, and duration of the detection values ​​of at least two independent sensing channels of the sensing component relative to the environmental baseline are all abnormal. The third evidentiary condition is that the identity information corresponding to the glass indicates that the target glass is a pre-verified breakable glass, the state detection unit indicates that it is in the glass installation state, the position of the striker relative to the target glass meets the preset contact conditions, the vehicle movement state meets the preset escape conditions, the energy storage of the action energy storage device is sufficient, and the system outputs a window breaking execution command.

[0015] According to an embodiment of the present invention, the method further includes: When the installation status is in free monitoring mode: Maintain the sensing components of the detachable vehicle warning and interlocking device and the remote sensing device of the detachable vehicle warning and interlocking window breaking system for early detection of vehicle thermal runaway; The control component determines whether to output alarm information to the alarm unit based on the data output by the sensing components of the detachable vehicle warning and interlocking device and the remote sensing device of the detachable vehicle warning and interlocking window breaking system. The alarm unit executes alarm operations based on the alarm information; Furthermore, the control component controls the mechanical safety mechanism of the window-breaking execution component to be in a state that prevents the window-breaking execution component from releasing.

[0016] As can be seen from the above technical solutions, the detachable vehicle warning and interlocking device, window breaking system, and control method provided by the present invention have the following beneficial effects: By incorporating a glass attachment component, the device becomes detachable from the vehicle window, enabling it to independently detect and break windows. A sensing component allows for timely detection of early-stage thermal runaway data, which is then transmitted to the control unit. When the device is mounted on the vehicle window, the control unit sends a release permission to the window-breaking execution component when the data acquired by the glass attachment component and the sensing component meets preset confirmation conditions. In a free-monitoring state, the sensing component remains in detection mode, while the device maintains its alarm function and prevents the window-breaking execution component from releasing. This allows the same unit to operate near potential pressure relief paths. This device enables early monitoring and can be fixed to an authenticated tempered glass side window when needed. It reduces the risk of accidental window breakage due to improper handling, incorrect glass installation, adsorption failure, or accidental triggering during driving. This addresses the technical problem of existing escape devices, which are simply combinations of sensors and vehicle window-breaking devices, failing to simultaneously ensure monitoring and escape effectiveness, or even having insufficient early warning capabilities or potential hazards. By incorporating a remote sensing device into the window-breaking system, the same unit can switch between detection and standby modes based on the scenario. This improves the probability of gas contact in the early stages of lithium battery thermal runaway without sacrificing escape execution capabilities, and also enhances the system's effectiveness through the inclusion of a vehicle interface. The system enables the processing unit to generate hazard evidence based on the increment, rate of change, duration, and sensor reliability of the detection values ​​output by each internal sensing unit relative to the individual environmental baseline. When the hazard evidence meets the first evidence condition, a warning verification operation is executed; when the hazard evidence meets the second evidence condition, a hazard confirmation operation is executed; and when the hazard confirmation operation is executed, the vehicle system is controlled to unlock the windows and lower the target window. Based on vehicle data from the vehicle interface, it is determined whether the target window is fully lowered within a preset time: if fully lowered, the window breaking request is cancelled; if not fully lowered, based on vehicle data... When the machine status, the situation of the people inside the vehicle, or the window breaking command is triggered manually, the control device executes the window breaking operation, making glass identity and installation quality necessary conditions for permitting the window breaking action, reducing ineffective impacts under conditions of laminated glass or loose adsorption; it realizes early warning and final window breaking classification, and reduces the risk of accidental window breaking at high speed by combining vehicle speed, occupant / manual confirmation and countdown, and solves the technical problems of existing fixed window sensing devices having limited detection positions, mismatch between movable detectors and window breaker status, glass type errors and adsorption failures that may lead to ineffective or accidental window breaking, and single point failures in network software that may bypass safety conditions.

The window breaking execution component 40 is disposed on the housing 10, and the window breaking execution component 40 performs the window breaking operation according to the release permission of the control component 50; The control component 50 is connected to the glass attachment component 20, the sensing component 30, and the window breaking execution component 40 via signal connection. When the device housing 10 is installed on the vehicle glass 00, and the data acquired by the glass attachment component 20 and the sensing component 30 meets the preset confirmation conditions, the control component 50 outputs a release permission to the window breaking execution component 40. When the device is in a free monitoring state, the sensing component 30 remains in a detection state, the device alarm function is on standby, and the window breaking execution component 40 is prohibited from releasing.

[0021] In some embodiments, the housing 10 can be completely removed from the vehicle glass 00 and placed in a free monitoring state, or it can be completely fixed to the vehicle glass 00 and placed in a glass installation state.

[0022] In some embodiments, the detachable vehicle warning and interlocking device further includes an independent power supply component, which includes a rechargeable main energy storage component, a solar panel, an external charging interface, and an action energy storage component that is isolated from or can be isolated from the main energy storage component. The action energy storage component supplies power to the alarm unit and / or the release component 43 when the voltage of the main energy storage component is lower than a preset voltage threshold.

[0023] In some embodiments, the housing 10 is divided into a sensing area, a controller area and an energy area. The sensing area is located at the rear end of the air intake. The monitoring component 30 is located in the sensing area. The control area and the energy area are separated by a partition.

[0024] In some embodiments, the main energy storage device may be a rechargeable lithium iron phosphate battery, the solar panel is kept charged by an energy harvesting circuit, the action energy storage device may be a supercapacitor or a high-rate branch isolated from the main energy storage device, and the solar panel is not the sole criterion for the availability of the device's safety functions.

[0025] In some embodiments, the housing 10 may be a flat ellipse with an adsorption unit on the side facing the glass, which is a ring-shaped silicone adsorption element. The adsorption unit is compressed by a flip handle to form a negative pressure. The status detection unit is connected to the adsorption chamber. A window breaking execution component 40 is provided in the center of the housing 10. The front end of the striker 44 of the window breaking execution component 40 faces the glass, and its stroke is limited by a metal guide sleeve. When the housing 10 is removed, the handle returns to the release position and pushes the mechanical safety component 45 of the window breaking execution component 40 into the lateral limiting groove of the striker 44 slider.

[0026] In some embodiments, a diffusion air inlet is provided around the periphery of the vehicle compartment side of the housing 10, and a hydrophobic and breathable membrane and a diffusion cavity are sequentially provided after the air inlet, so that the housing 10 can introduce gas from the vehicle compartment side to the sensing component 30 in both the free monitoring state and the glass installation state. The sensing component 30 is disposed in the sensing area of ​​the housing 10. The sensing component 30 may include an electrolyte vapor sensor, a hydrogen / carbon monoxide composite sensor, a particulate matter sensor, a temperature and humidity sensor, and a housing 10 temperature sensor. The control component 50 samples at a configurable period of 1 to 60 seconds and switches to a high sampling rate when there is an abnormal rise.

[0027] In some embodiments, an adsorption chamber is provided between the vehicle window glass 00 and the adsorption unit. The adsorption unit forms a negative pressure after compression. The state detection unit is connected to the adsorption chamber. The state detection unit determines the installation state of the device based on the pressure state of the adsorption chamber.

[0029] In some embodiments, the glass attachment assembly 20 further includes a glass reading unit. When the state detection unit determines that the installation state of the device is a glass installation state, the glass reading unit reads the glass identification tag, obtains the identification information corresponding to the glass, and outputs it to the control assembly 50.

[0030] In some embodiments, the control component 50 can prevent the electric release by mechanical safety 45 and / or independent hardware gating, thereby preventing the release of the firing pin 44 by mechanical safety 45 and / or hardware gating in the free monitoring state, reducing personal risks caused by handling, dropping, transportation or misoperation.

[0031] In some embodiments, the glass reading unit is disposed on the housing 10, and the glass identification label is a passive label containing at least two of the following: vehicle model, target window position, glass type, permitted installation area, verification version, and verification code; the passive label is installed by installation service personnel affixing it to a predetermined tempered side window position based on vehicle glass corner markings, model database, and physical verification; and when the glass reading unit fails to read the glass identification label, fails to read the verification, or reads the label content indicating laminated glass, the independent hardware gate remains disconnected.

[0032] In some embodiments, the sensing component 30 includes a plurality of internal sensing units, which are respectively disposed in different types of sensing channels. The internal sensing units are used to acquire different types of detection values ​​and output them to the control component 50.

[0033] In some embodiments, the different types of sensing channels may include a first sensing channel for detecting carbonate electrolyte vapor and a second sensing channel for detecting at least one of hydrogen, carbon monoxide, carbon dioxide, particulate matter, broad-spectrum volatile organic compounds or temperature, wherein the first sensing channel and the second sensing channel have different detection principles.

[0034] In some embodiments, the window-breaking execution component 40 includes an energy storage component 41, a locking component 42, a releasing component 43, a striking pin 44, and a mechanical safety component 45.

[0035] In some embodiments, the mechanical safety element 45 is mechanically associated with the glass attachment assembly 20 such that when the housing 10 is in a free monitoring state, the mechanical safety element 45 prevents the striker 44 from performing a window-breaking stroke toward the outside of the housing 10.

[0036] In some embodiments, the glass attachment assembly 20 further includes an adsorption actuation member connected to the mechanical safety member 45. The adsorption actuation member is configured to drive the mechanical safety member 45 out of the limiting position of the striker 44 during the adsorption process and to drive the mechanical safety member 45 into the limiting position during the de-adsorption process.

[0037] In some embodiments, the window breaking actuator 40 may be a replaceable sealed box, the energy storage component 41 may be a pre-compression spring, the locking component 42 may be a metal catch, the release component 43 may be a holding electromagnet or a micro motor driven fork, the release component 43 only needs to overcome the catch holding force, the firing pin 44 may be a tungsten carbide firing pin 44 captured by the housing 10, and the side of the housing 10 facing the glass is also provided with a flexible debris protection ring 46 around the firing pin 44, the spring energy is used to drive the captured tungsten carbide firing pin 44, wherein the window breaking actuator 40 is provided with a production lock and a position code, and the independent hardware gate remains disconnected when a qualified cartridge is not installed; The protective ring 46 forms a local enclosure after adsorption. After the firing pin 44 is fired, it is captured by the stop ring and cannot detach from the housing 10. The acceleration / acoustic signal is used to determine whether glass breakage has occurred. It is only used for confirmation after action and does not replace glass authentication.

[0038] In some embodiments, the state detection unit includes one or more of a negative pressure detection element, a contact detection element, or an attitude detection element; the negative pressure detection element is used to detect the pressure in the adsorption chamber between the adsorption unit and the vehicle glass 00; the contact detection element is used to detect the gap between the guide end of the impact pin 44 and the vehicle glass 00; the attitude detection element is used to detect the attitude of the housing 10 relative to the vehicle glass 00; when the negative pressure detection element detects that the pressure is lower than a preset threshold, the pressure drop rate is abnormal, the contact detection element detects a lack of contact, or the attitude detection element detects an incorrect attitude, the control component 50 cancels the standby state and issues a reinstallation prompt.

[0039] In some embodiments, the control component 50 includes a processing unit and an alarm unit, wherein the processing unit forms hazard evidence based on the increment, rate of change, duration, and sensor reliability of the detection values ​​output by each internal sensing unit relative to an individual environmental baseline. When the dangerous evidence meets the first evidence condition, an early warning operation is performed. The early warning operation is as follows: the alarm unit is controlled to output early alarm information and the window breaking execution component 40 is prohibited from being released. When the dangerous evidence meets the second evidence condition, a danger confirmation operation is performed. The danger confirmation operation is as follows: the alarm unit is controlled to output a danger alarm message and the window breaking execution component 40 is prohibited from being released. When the dangerous evidence meets the third evidence condition, a release permission is output to the window breaking execution component 40; The first evidentiary condition is that any of the detection values ​​of the sensing component 30 shows an anomaly in increment, rate of change, or duration relative to the environmental baseline; The second evidentiary condition is that the increment, rate of change, and duration of the detection values ​​of at least two independent sensing channels of the sensing component relative to the environmental baseline are all abnormal. The third evidentiary condition is that the identity information corresponding to the glass indicates that the target glass is a pre-verified breakable glass, the state detection unit indicates that it is in the glass installation state, the position of the striker relative to the target glass meets the preset contact conditions, the vehicle movement state meets the preset escape conditions, the energy storage of the action energy storage device is sufficient, and the system outputs a window breaking execution command.

[0040] In some embodiments, the control component 50 forms a rolling median baseline for each channel, calculates the electrolyte vapor increment, hydrogen / carbon monoxide increment, particulate matter increment, temperature change rate, and corresponding duration, and adjusts the confidence level based on humidity, alcohol / cleaning agent characteristics, and sensor health status to form evidence of danger.

[0041] In some embodiments, outputting alarm information to the alarm unit specifically includes outputting voice and light signals and starting a countdown. The aftermarket unit only requests release from the independent hardware gate of the window breaking execution component 40 when the IMU determines that the vehicle is stationary or in a permissible low-speed state, the device is in the glass installation state, all installation interlocks are normal, the action energy is sufficient, and it obtains manual double action confirmation or meets the preset serious danger conditions. In addition, mobile phone or cloud commands cannot form release permission on their own.

[0042] In the above embodiments, the networking function is isolated from the action security domain, which ensures that APP, cloud or OTA failures cannot trigger window breaking independently.

[0043] In some embodiments, the sensing component 30 further includes an inertial measurement unit disposed within the housing 10, the inertial measurement unit being used to acquire the motion state of the vehicle when the device is in a glass-mounted state.

[0044] In some embodiments, when the free monitoring state is in progress, the control component 50 keeps the sensing component 30 and the alarm unit operational, while simultaneously prohibiting the release member 43 from operating; when the glass is installed, a release permit for the release member 43 is generated only when the identity information corresponding to the glass indicates that the target glass is a pre-verified breakable glass, the status detection unit indicates that it is in the glass installation state, the position of the striker 44 relative to the target glass meets a preset contact condition, the vehicle movement state meets a preset escape condition, and the danger evidence formed by the sensing component 30 meets a preset confirmation condition. The preset contact condition can be greater than 5mm; the preset confirmation condition is a third evidence condition; the vehicle motion state can be provided by an inertial measurement unit and / or a certified vehicle interface located in the housing 10; when reliable vehicle speed information is not obtained, the preset escape condition includes at least the inertial measurement unit indicating that the vehicle is stationary or below a preset motion threshold within a preset time period.

[0046] In some embodiments, the hazard evidence of the control component 50 is corrected by at least one of temperature, humidity, and pre-stored interference modes.

[0047] In some embodiments, the control component 50 includes a main controller that performs communication, user interface, or software update functions, and a hardware security gating circuit independent of the main controller, i.e., an independent hardware gating circuit that grants series permission to the power supply path of the release element 43 based on the installation status detection device, the position of the mechanical safety device 45, and the energy storage status of the action.

[0048] Furthermore, the present invention also provides a detachable vehicle warning and interlocking window breaking system.

[0050] In some embodiments, the remote sensing device sends gas evidence with timestamps, health status, and authentication information, namely, early-stage vehicle thermal runaway characteristic parameters and remote sensing data, to the device via a wired or certified wireless link.

[0051] In some embodiments, the system further includes: The system communicates with the vehicle via the vehicle interface terminal. The vehicle interface terminal is used to acquire vehicle data, which includes at least reliable vehicle speed information, door lock status information, window position information, collision information, and high voltage power-off information. The system is configured to control the vehicle infotainment system to unlock the windows and lower the target windows when the control components of the detachable vehicle warning and interlocking device perform a hazard confirmation operation. Based on the vehicle data obtained from the vehicle interface, determine whether all the target windows have been lowered within a preset time: With all the target vehicle windows lowered, a request to cancel window breaking is sent to the detachable vehicle warning and interlocking device; Alternatively, if the target vehicle window is not fully lowered, the vehicle system is in an authorized state, and there are people inside the vehicle, or if there is a manually triggered window-breaking command in the vehicle data obtained from the vehicle interface, a window-breaking execution command is output to the detachable vehicle warning and interlocking device so that the window-breaking execution component of the detachable vehicle warning and interlocking device performs the window-breaking operation.

[0052] In some embodiments, if communication between the system and the vehicle is interrupted when the target vehicle window is not fully lowered, the detachable vehicle warning and interlocking device will degrade to a local alarm, preventing it from automatically releasing due to loss of connection.

[0053] In some embodiments, the vehicle interface is used to acquire at least two of the vehicle speed, door lock status, and window position, and after the dangerous evidence meets the preset confirmation conditions, it first performs door unlocking and / or target window lowering. Only when the target window is not lowered within a preset time and the other release conditions are met is the window breaking component action allowed.

[0054] Furthermore, the present invention also provides a detachable vehicle warning and interlocking window breakage control method.

[0055] See appendix Figure 7 , Figure 7 This is a schematic diagram of the main flow of a detachable vehicle warning and interlocking window-breaking control method according to an embodiment of the present invention. Figure 7 As shown, a detachable vehicle warning and interlocking window-breaking control method in this embodiment of the invention is applied to any of the above-mentioned detachable vehicle warning and interlocking window-breaking systems. The method includes the following steps: Step S1: The sensing component of the detachable vehicle warning and interlocking device acquires the detection data of the early stage of vehicle thermal runaway and sends it to the control component of the detachable vehicle warning and interlocking device. Step S2: The remote sensing device of the detachable vehicle warning and interlocking window breaking system acquires the early characteristic parameters of vehicle thermal runaway and remote sensing data and sends them to the detachable vehicle warning and interlocking device. The remote sensing data includes at least the timestamp of the early characteristic parameters of vehicle thermal runaway, the health status of the remote sensing device, and authentication information. Step S3: The glass attachment assembly of the detachable vehicle warning and interlocking device acquires the installation status of the housing and the target window and outputs it to the control assembly; Step S4: When the installation state is glass installation state, the glass reading unit reads the glass identification tag, obtains the identification information corresponding to the glass, and outputs it to the control component; The control component forms hazard evidence based on the increment, rate of change, duration, and sensor reliability of the detection values ​​output by the internal sensing units of each sensing component and each remote sensing device relative to the individual environmental baseline. When the dangerous evidence meets the first evidence condition, an early warning operation is performed. The early warning operation is as follows: the alarm unit is controlled to output early alarm information, and the window breaking execution component is prohibited from being released. When the dangerous evidence meets the second evidence condition, a dangerous confirmation operation is performed. The dangerous confirmation operation is: controlling the alarm unit to output dangerous alarm information and prohibiting the window breaking execution component from releasing. When the dangerous evidence meets the third evidence condition, a release permission is issued to the window breaking execution component of the detachable vehicle warning and interlocking device; The first evidentiary condition is that any of the detection values ​​of the sensing component shows an anomaly in its increment, rate of change, or duration relative to the environmental baseline; The second evidentiary condition is that the increment, rate of change, and duration of the detection values ​​of at least two independent sensing channels of the sensing component relative to the environmental baseline are all abnormal. The third evidentiary condition is that the identity information corresponding to the glass indicates that the target glass is a pre-verified breakable glass, the state detection unit indicates that it is in the glass installation state, the position of the striker relative to the target glass meets the preset contact conditions, the vehicle movement state meets the preset escape conditions, the energy storage of the action energy storage device is sufficient, and the system outputs a window breaking execution command.

[0056] In some embodiments, the confirmation of dangerous operation further includes: outputting alarm information to the alarm unit; when the dangerous evidence does not meet the conditions for third evidence, the control component controls the mechanical safety device of the window breaking execution component to be in a state that prevents the window breaking execution component from being released, and outputs a corresponding evacuation prompt to the alarm unit.

[0057] In some embodiments, the method further includes: When the installation status is in free monitoring mode: Maintain the sensing components of the detachable vehicle warning and interlocking device and the remote sensing device of the detachable vehicle warning and interlocking window breaking system for early detection of vehicle thermal runaway; The control component determines whether to output alarm information to the alarm unit based on the data output by the sensing components of the detachable vehicle warning and interlocking device and the remote sensing device of the detachable vehicle warning and interlocking window breaking system. The alarm unit executes alarm operations based on the alarm information; Furthermore, the control component controls the mechanical safety mechanism of the window-breaking execution component to be in a state that prevents the window-breaking execution component from releasing.

[0058] In some embodiments, the control component controls the mechanical safety mechanism of the window-breaking execution component to prevent the window-breaking execution component from releasing, specifically by keeping the mechanical safety mechanism in a limited position.

[0059] In some embodiments, the control component determines the control state of the detachable vehicle warning and interlocking window breaking system based on evidence of danger; When the evidence of danger does not meet the first evidence condition, the control state of the detachable vehicle warning and interlocking window breaking system is determined to be normal. When the dangerous evidence meets the first evidence condition, the control state of the detachable vehicle warning and interlocking window breaking system is determined to be an early abnormal state. When the evidence of danger meets the conditions for second evidence, the control state of the detachable vehicle warning and interlocking window breaking system is determined to be a confirmed dangerous state. When the evidence of danger meets the conditions for third evidence, the control state of the detachable vehicle warning and interlocking window breaking system is determined to be the escape action state. In the early abnormal state, only the alarm unit is activated and no release permission is generated.

[0060] In some embodiments, the hazard evidence may include the credibility of obtaining an electrolyte vapor channel and at least one channel of different physical principles; excluding or reducing the weight of evidence consistent with interference patterns of alcohol, perfume, cleaning agents, smoking, or exhaust fumes; and entering a confirmed hazard state when conditions are consistently met by at least two channels of different physical principles or when a serious hazard condition is met in combination with human / occupant evidence.

[0061] In some embodiments, the method further includes outputting an audio-visual or voice countdown before the output release permission is granted, and the receiving entity cancels the input; When the device re-enters free monitoring state, attachment reliability decreases, glass compatibility information fails, vehicle motion status is not met, or hardware safety gate self-test fails, the release permission is revoked and the mechanical safety device enters the limit position.
