Description

Technical Field

[0001] This disclosure relates to the field of vehicle technology, and in particular to a rescue system and method for vehicles that have fallen into water. Background Technology

[0002] When vehicles cross bridges, lake embankments, or flooded culverts, they may fall into the water, seriously threatening the lives of those inside. Rescuing a vehicle in this situation relies heavily on the self-rescue abilities of the occupants and the timely intervention of rescue personnel. However, occupants in a state of panic are often unable to successfully save themselves, and waiting for rescue can be lengthy. Therefore, vehicle-into-water accidents pose a serious threat to the lives of those inside the vehicle. Summary of the Invention

[0003] To address the aforementioned technical problems, this disclosure provides a rescue system and method for vehicles that have fallen into water.

[0004] According to one aspect of this disclosure, a vehicle submerged in water rescue system is provided, the rescue system comprising: a region controller and a region control system for multiple vehicle body regions; each region control system comprising: an inflation controller and an airbag connected to the inflation controller; wherein, there are multiple region controllers, and the inflation controllers in the multiple region control systems are connected to the multiple region controllers one by one; or, there is one region controller, and the inflation controllers in the multiple region control systems are all connected to the region controller;

[0005] The inflation controller is used to inflate the airbag when a vehicle submerged in water signal is received in the target vehicle area; wherein, the target vehicle area is the vehicle area corresponding to the current inflation controller.

[0006] The area controller is used to control the brake motor and drive motor of the target vehicle body area to stop output when the vehicle falls into water signal is obtained in the target vehicle body area.

[0007] According to another aspect of this disclosure, a method for rescuing a vehicle that has fallen into water is also provided, the method being applied to the vehicle rescue system described above; the method includes:

[0008] Acquire vehicle submersion signal in the target vehicle body area;

[0009] The airbags are inflated by the inflation controller according to the vehicle falling into the water signal;

[0010] The area controller controls the brake motor and drive motor of the target vehicle body area to stop outputting based on the vehicle falling into water signal.

[0011] According to another aspect of this disclosure, an electronic device is also provided, the electronic device comprising:

[0012] processor;

[0013] Memory used to store the processor's executable instructions;

[0014] The processor is configured to read the executable instructions from the memory and execute the instructions to implement the above-mentioned vehicle-to-water rescue method.

[0015] According to another aspect of this disclosure, a computer-readable storage medium is also provided, the storage medium storing a computer program for performing the above-described vehicle-to-water rescue method.

[0016] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0017] The technical solution provided in this disclosure includes at least a zone controller and multiple zone control systems for different vehicle body areas. Each zone control system includes, but is not limited to, an inflation controller and an airbag connected to the inflation controller. There are multiple zone controllers, with each inflation controller in the multiple zone control systems connected to one of the multiple zone controllers; or, there is one zone controller, with each inflation controller in the multiple zone control systems connected to the zone controller. The inflation controller inflates the airbag when a vehicle submerged signal is received in the target vehicle body area; the target vehicle body area is the vehicle body area corresponding to the current inflation controller. The zone controller stops the output of the brake motor and drive motor in the target vehicle body area when a vehicle submerged signal is received in the target vehicle body area. This solution provides a rescue system with zone control systems configured for different vehicle body areas. Each vehicle body area can independently control the inflation of the airbags and the output of the brake motor and drive motor, making rescue control more flexible and convenient. In particular, compared to general non-zoned overall control, this solution achieves better control performance when zone control systems for different vehicle body areas are used in combination. For any target vehicle body area, when the inflation controller receives a signal that the vehicle in its target vehicle body area has fallen into the water, the inflation controller inflates the airbag in that target vehicle body area. This allows the airbag to expand and deploy rapidly. The inflated airbag increases the vehicle's buoyancy in the water, slowing down the vehicle's sinking or making the vehicle float, thus buying time for rescue and reducing the difficulty of rescue. By controlling the brake motor and drive motor of the target vehicle body area to stop output through the area controller, the safety of the vehicle when it falls into the water can be improved, the vehicle's kinetic energy can be reduced, and the risk of injury to the people inside the vehicle can be reduced.

[0026] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0028] In response to vehicle submersion accidents, this disclosure provides a vehicle rescue system and method. This solution allows for independent rescue control of different vehicle body areas. For each area, when the vehicle falls into water, an inflation controller inflates the inflatable floats (airbags) to increase buoyancy, causing the vehicle to float or slow its descent, thus buying time for rescue and reducing the difficulty of the rescue. Furthermore, the area controller stops the output of the drive motor and brake motor, improving safety when the vehicle falls into water. For ease of understanding, the embodiments of this disclosure are described in detail below.

[0029] Figure 1 and Figure 2 This is a schematic diagram of the architecture of a vehicle rescue system for submerged vehicles, provided as an embodiment of this disclosure. The vehicle rescue system may include: a zone controller and multiple zone control systems for different vehicle body zones; each zone control system includes: an inflation controller and an airbag connected to the inflation controller.

[0030] Among them, such as Figure 1 As shown, there are multiple area controllers, and the inflation controllers in the multiple area control systems are connected to each of the multiple area controllers. In this system architecture, each vehicle body area, or rather each area control system, is independently configured with a dedicated area controller, further increasing the flexibility of rescue control.

[0031] Or, such as Figure 2 As shown, there is one area controller, and the inflation controllers in multiple area control systems are all connected to the area controller. In this system architecture, multiple area control systems share one area controller. Under the premise that each area control system can operate independently, costs can also be reduced by sharing the area controller.

[0032] In the aforementioned vehicle submersion rescue system, the airbag inflator is used to inflate the airbag when a vehicle submersion signal is received in the target vehicle area; the target vehicle area is the vehicle area corresponding to the current airbag inflator; the area controller is used to control the brake motor and drive motor of the target vehicle area to stop output when a vehicle submersion signal is received in the target vehicle area.

[0033] Possible methods for obtaining vehicle submersion signals in the target vehicle area include: the user actively submitting a vehicle submersion signal in the target vehicle area through human-computer interaction; detecting real-time pressure using water pressure sensors installed in different vehicle body areas, and generating a vehicle submersion signal for the target vehicle body area where the water pressure sensor is located when the real-time water pressure exceeds a preset pressure threshold; determining vehicle submersion by performing image recognition on driving images captured by a camera and generating a vehicle submersion signal for the target vehicle body area; or, simultaneously generating a vehicle submersion signal for the target vehicle body area based on the pressure from the water pressure sensor and the driving images from the camera. It is understood that the above are merely examples of obtaining vehicle submersion signals in the target vehicle body area and are not intended to be limiting.

[0034] In this embodiment, when the inflation controller receives a signal indicating that the vehicle has fallen into water in the target area, it can inflate the airbags connected to it. The inflation controller has a built-in independent power supply; this power supply provides energy to the inflation controller when the vehicle experiences a power outage, enabling the inflation controller to inflate the airbags. Even when other vehicle components malfunction due to water damage, the built-in independent power supply ensures that the inflation controller can still control the airbag inflation.

[0035] The inflation controller has a built-in gas generator. The controller ignites the gas generator with an electric current to produce a large amount of gas. This gas is then rapidly injected into the airbag through the pipe connecting the controller and the airbag, causing it to inflate and deploy quickly. The inflated airbag increases the vehicle's buoyancy in water, slowing its sinking or allowing it to float, buying time for rescue and reducing the difficulty of the rescue.

[0036] Furthermore, when the area controller receives a signal that a vehicle has fallen into water in the target vehicle area, it can control the brake motor in the target vehicle area to brake and control the drive motor to stop output within a certain period of time (such as 3 seconds), locking the wheels. This can improve the safety of the vehicle when it falls into the water, reduce the vehicle's kinetic energy, and reduce the risk of injury to the people inside the vehicle.

[0037] In some embodiments, the region control system for multiple vehicle body areas includes, for example, a region control system for the front side of the vehicle body and a region control system for the rear side of the vehicle body. Alternatively, to achieve more refined control, the region control system for multiple vehicle body areas may include, for example, a region control system for the left front side of the vehicle body, a region control system for the right front side of the vehicle body, a region control system for the left rear side of the vehicle body, and a region control system for the right rear side of the vehicle body.

[0038] Taking a multi-area vehicle body control system, including a regional control system for the front area and a regional control system for the rear area, as an example, refer to... Figure 1 or Figure 2As shown, in the area control system of the front side of the vehicle body, there are multiple airbags, which are respectively located at the left front and right front of the vehicle. Accordingly, the inflation controller includes: a first inflation controller for controlling the left front airbag and a second inflation controller for controlling the right front airbag.

[0039] In the area control system for the rear side of the vehicle, there are multiple airbags, which are respectively located on the left and right rear sides of the vehicle. Accordingly, the inflation controllers include: a third inflation controller for controlling the left rear airbag and a fourth inflation controller for controlling the right rear airbag.

[0040] In the above embodiments, the airbag material can be made of special rubber, which has the characteristics of high strength, wear resistance and good airtightness.

[0041] In this embodiment, airbags of different sizes and numbers can be installed on vehicles according to their weight, volume, and load capacity. This ensures that the buoyancy generated by the fully inflated airbags can support the vehicle, while avoiding the waste of resources caused by using excessively large or numerous airbags on smaller vehicles. An example of the buoyancy design standard for a single airbag is as follows:

[0042] The design buoyancy of a single airbag is 4KN, 5KN, 6KN, 7KN, and 8KN respectively; the deployment area of ​​a single airbag is 0.5m2, 0.75m2, 1m2, 1.25m2, and 1.5m2 respectively.

[0043] The aforementioned airbags can be applied to, for example, sedans with a curb weight of 1.2-1.8 tons and a payload of 0.35-0.5 tons, SUVs with a curb weight of 1.5-2.5 tons and a payload of 0.35-0.5 tons, MPVs with a curb weight of 1.8-2.2 tons and a payload of 0.5-0.8 tons, and so on, and will not be listed here.

[0044] In practical scenarios, the airbags can be installed on the mudguards of all four wheels. When the airbags deploy and fill with gas, the fully deployed airbags can wrap around the wheels. Alternatively, the airbags can be installed on the bottom of the vehicle and on the left and right sides of the vehicle, with at least one airbag installed on the bottom and on each side.

[0045] Based on the above embodiments, the area control system may further include a water pressure sensor connected to both the area controller and the inflation controller. Therefore, in a vehicle submerged in water rescue system, the area control system for each vehicle body area may include: a water pressure sensor, an inflation controller, an airbag, a brake motor, and a drive motor; the water pressure sensor, area controller, and inflation controller are interconnected, the airbag is connected to the inflation controller, and both the brake motor and the drive motor are connected to the area controller.

[0046] In this embodiment, the water pressure sensor is used to collect real-time pressure and transmit the real-time pressure to the area controller and the inflation controller.

[0047] Specifically, in order to measure water pressure changes more accurately, water pressure sensors can be installed at the bottom of the vehicle. Taking the area control system in the front area of ​​the vehicle as an example, water pressure sensors can be installed at the bottom of the left front and right front of the vehicle respectively.

[0048] In the event of a vehicle falling into water, a water pressure sensor can measure and collect the pressure generated by the water, and the pressure changes with the water depth. Based on the collected pressure, the depth of the vehicle in the water can be accurately identified.

[0049] for Figure 2 The rescue system shown connects the same area controller to water pressure sensors in multiple areas of the vehicle body. Alternatively, in... Figure 1 In the rescue system shown, within the same vehicle body area, the area controller is connected to at least one water pressure sensor. For example, in the area control system of the front side of the vehicle body, the area controller is connected to the left front water pressure sensor and the right front water pressure sensor.

[0050] Each water pressure sensor transmits its collected real-time pressure data to the area controller. In this case, the area controller is further configured to generate a vehicle submersion signal and send it to the inflation controller if the real-time pressure of at least one water pressure sensor exceeds a preset first pressure threshold for a first duration (e.g., 5 seconds). The real-time pressure of the aforementioned at least one water pressure sensor can be... Figure 2 The real-time pressure of the water pressure sensor in at least one area of ​​the vehicle body, or alternatively... Figure 1 Real-time pressure of at least one water pressure sensor in the same vehicle body area.

[0051] Specifically, the area controller comprehensively determines whether at least one water pressure sensor's real-time pressure exceeds a preset first pressure threshold for a sustained first duration; this first pressure threshold represents the minimum pressure a vehicle experiences when submerged in water. If so, a vehicle submersion accident can be determined, and a vehicle submersion signal is generated and synchronized with the inflation controller. In this embodiment, by considering the real-time pressure from multiple water pressure sensors and the duration of the submersion, the system can more accurately determine whether a vehicle submersion accident has actually occurred, resulting in a more accurate vehicle submersion signal and avoiding false alarms.

[0052] Alternatively, in another embodiment, the water pressure sensor, inflation controller, and airbag corresponding to the same vehicle body area are connected sequentially. For example, the left front water pressure sensor, the first inflation controller, and the left front airbag are connected sequentially. They all belong to the left front area of ​​the vehicle body and their common function is to detect whether the left front area of ​​the vehicle has fallen into water, and control the inflation of the left front airbag in the event of water submersion. In this case, the inflation controller is also used to generate a vehicle water submersion signal if it does not receive a vehicle water submersion signal from the area controller, and the real-time pressure is greater than a first pressure threshold for a second duration; wherein the second duration is greater than the first duration.

[0053] In a vehicle submerged in water, the airbag inflation controller, which directly inflates the airbags, must have a high waterproof rating to ensure proper underwater operation. However, considering manufacturing costs, components like the area controller typically have a lower waterproof rating than the inflation controller. Therefore, when a vehicle submerges in water, these components may be damaged, preventing the area controller from sending a submerged signal to the inflation controller.

[0054] To address this issue, the water pressure sensor can directly transmit the real-time pressure it collects to the inflation controller. The inflation controller then determines whether the real-time pressure from the water pressure sensor exceeds a preset first pressure threshold for a second duration. This second duration is longer than the first duration. Firstly, it allows the controller to wait for a vehicle submersion signal synchronized from the area controller during this second duration. If no such signal is received from the area controller, the inflation controller itself determines whether a vehicle submersion accident has occurred based on the real-time pressure. Secondly, compared to the area controller, the inflation controller, which is only connected to the water pressure sensor in its target vehicle area, can obtain a smaller amount of pressure data. Therefore, the longer second duration helps avoid misjudging a submersion accident.

[0055] Furthermore, if the inflation controller does not receive a vehicle submerged in water signal from the area controller, and the real-time pressure is greater than the first pressure threshold for a second duration, the inflation controller generates a vehicle submerged in water signal.

[0056] Therefore, in this embodiment, the vehicle submersion signal can be generated by the area controller based on the real-time water pressure from at least one water pressure sensor and a first duration. This method generates a more accurate vehicle submersion signal and avoids misjudgment. Alternatively, in this embodiment, the vehicle submersion signal can also be generated by the inflation controller based on the real-time water pressure and a second duration. This method can compensate for the problem of damage to the area controller due to water immersion and still ensures the accuracy of the generated vehicle submersion signal.

[0057] In the above embodiments, the inflation controller determines the vehicle submersion signal based on the real-time water pressure measured by the water pressure sensor, and then inflates the airbag; similarly, the area controller determines the vehicle submersion signal based on the real-time water pressure measured by the water pressure sensor, and then controls the brake motor and drive motor to stop output. This solution, through a precise water pressure sensor and an inflation controller for triggering the airbag, can accurately identify the vehicle submersion signal and promptly trigger the airbag inflation, improving system reliability and response speed, and reducing rescue difficulty; simultaneously, by controlling the brake motor and drive motor to stop output, it enhances safety when the vehicle is submerged.

[0058] In this embodiment, the vehicle-to-water rescue system may further include: a central computing unit connected to a regional controller and a network controller connected to the central computing unit. Based on this, as... Figure 1 As shown, a vehicle-to-water rescue system may include: a central computing unit, a network controller, multiple regional controllers, and multiple regional control systems; the multiple regional control systems are connected to the multiple regional controllers one by one, and the central computing unit is specifically connected to each regional controller. Alternatively, as... Figure 2 As shown, the vehicle-to-water rescue system may include: a central computing unit, a network controller, a regional controller, and multiple regional control systems; the multiple regional control systems are connected to the regional controller, and the central computing unit is connected to the regional controller.

[0059] The central computing unit is used to receive vehicle status information sent by the regional controller and send alarm commands to the network controller based on the vehicle status information. The vehicle status information includes, but is not limited to: vehicle falling into water signal, real-time water pressure, airbag deployment signal, brake motor operating status and drive motor operating status.

[0060] The network controller is used to send rescue alarm information to the rescue platform according to alarm commands.

[0061] In a specific embodiment, the area controller corresponding to the target vehicle body area where the vehicle fell into the water sends a vehicle-in-water signal to the central computing unit; the central computing unit determines, based on the vehicle-in-water signal and other vehicle status information, whether the conditions for issuing a rescue order to the rescue platform are met; such conditions include one or more of the following:

[0062] a) Receives a vehicle submerged in water signal from the area controller for at least N1 (e.g., N1=2) vehicle body areas; this indicates that multiple body areas of the vehicle have been submerged, which is a critical situation and requires the intervention of external rescue forces.

[0063] b) The real-time pressure is greater than the preset first pressure threshold and continues to increase; this indicates that the vehicle is sinking continuously, which is a critical situation and requires the intervention of external rescue forces.

[0064] c) Receives deployment signals for at least N2 airbags; this situation is similar to situation a) above.

[0065] d) The brake motor is in restricted operation and / or the drive motor is in restricted operation.

[0066] When the central computing unit determines that at least one of the above conditions is met based on the vehicle status information, it sends an alarm command to the network controller. The network controller then sends a rescue alarm message to the rescue platform based on the alarm command. Upon receiving the rescue alarm message, the rescue platform's customer service personnel can communicate with the vehicle owner to inquire about their current situation and whether rescue is needed. If the owner does not respond or requires rescue, the platform will contact the local rescue department to organize rescue operations based on the vehicle's current network location information.

[0067] Furthermore, in this embodiment, after the vehicle escapes the predicament of falling into the water, the inflation controller is also used to disconnect the connecting pipe between the airbag and the airbag when the airbag deactivation signal of the target vehicle body area is obtained, so as to deflate the airbag; wherein, the airbag deactivation signal includes: a deactivation signal initiated by the user, or a deactivation signal generated when the real-time water pressure collected by the water pressure sensor is less than a preset second pressure threshold and continues for a fourth duration;

[0068] The area controller is also used to release the restrictions on the drive motor and brake motor of the target vehicle area when the airbag deflation end signal is received; wherein the airbag deflation end signal includes: a user-initiated end signal, or an end signal generated five hours after the airbag closing signal is generated.

[0069] In specific embodiments, the shutdown signal can be obtained through the following examples.

[0070] Example 1: After the vehicle escapes the predicament of being submerged in water, the user can actively initiate a signal to deactivate the airbags in the target vehicle area.

[0071] Example 2: A water pressure sensor collects real-time water pressure in the target area of ​​the vehicle body; the area controller and / or inflation controller receive the real-time water pressure and determine whether the real-time water pressure is lower than a preset second pressure threshold, such as 2950 Pa, which is the pressure at which the vehicle can escape the water malfunction. If the real-time water pressure is lower than the preset second pressure threshold for a period of time, a shutdown signal is generated.

[0072] Example 3: A water pressure sensor collects real-time water pressure in the target area of ​​the vehicle body; the area controller and / or the inflation controller receive the real-time water pressure and determine whether the real-time water pressure is lower than a preset second pressure threshold. If the real-time water pressure is lower than the preset second pressure threshold and remains lower for a fourth duration, a quasi-shutdown signal is generated and sent to the central computing unit. The central computing unit generates a selection prompt message on whether to shut down the inflation controller based on the quasi-shutdown signal; for example, it controls the vehicle microphone to play the selection prompt message on whether to shut down the inflation controller based on the quasi-shutdown signal, and it controls the central control display screen to display the selection prompt message on whether to shut down the inflation controller based on the quasi-shutdown signal. After receiving the user's selection result of shutting down the inflation controller, the central computing unit generates the final shutdown signal.

[0073] When the airbag deactivation signal is received in the target vehicle area, the inflation controller disconnects the connection pipe between itself and the airbag to deflate the airbag.

[0074] After the airbag deflation is complete, the user can actively initiate an airbag deflation end signal to indicate that the airbag has finished deflating. Alternatively, the airbag deflation end signal can be generated five time intervals after the airbag closing signal is generated; this fifth time interval is the duration required for the airbag to fully deflate through actual testing; the airbag deflation begins when the airbag closing signal is generated, and after the fifth time interval has elapsed, the airbag is considered to have finished deflating, and thus the airbag deflation end signal is generated.

[0075] Furthermore, when the area controller receives the airbag deflating end signal, it releases the restrictions on the drive motor and brake motor of the target vehicle area, specifically by releasing the torque output restriction on the drive motor and releasing the brake motor.

[0076] like Figure 3 As shown, based on the vehicle submersion rescue system provided in the above embodiments, this embodiment provides an automatic vehicle submersion rescue method, including the following steps.

[0077] (1) Real-time pressure is collected by water pressure sensors in each vehicle body area.

[0078] (2) When the real-time pressure of at least one water pressure sensor is greater than a preset first pressure threshold and lasts for a first duration, the area controller generates a vehicle falling into water signal in the target vehicle area and sends the vehicle falling into water signal to the inflation controller; or, when the real-time pressure is greater than the first pressure threshold and lasts for a second duration, the inflation controller generates a vehicle falling into water signal in the target vehicle area.

[0079] (3) When the inflation controller receives a signal that the vehicle has fallen into the water in the target body area, it inflates the airbag.

[0080] Specifically, water pressure sensors, inflation controllers, and airbags are installed at the four corners of the vehicle's underside, respectively. The water pressure sensors collect the pressure exerted by the water on the vehicle, and the pressure increases with water depth, thus accurately measuring changes in water pressure. The inflation controller is connected to the water pressure sensors. When the real-time pressure exceeds a preset first pressure threshold, the controller inflates the airbags. The inflated airbags generate buoyancy, preventing the vehicle from sinking rapidly and providing more escape time for occupants, thus improving safety when the vehicle falls into water.

[0081] (4) When the area controller receives a signal that a vehicle has fallen into water in the target vehicle area, it controls the brake motor and drive motor in the target vehicle area to stop outputting.

[0082] (5) The area controller sends a vehicle submerged in water signal to the central computing unit; the central computing unit receives vehicle status information, which includes: the vehicle submerged in water signal, real-time water pressure, airbag deployment signal, brake motor operating status, and drive motor operating status. Then, the central computing unit sends an alarm command to the network controller based on the vehicle status information; the network controller sends a rescue alarm message to the rescue platform based on the alarm command.

[0083] (6) When the airbag closure signal of the target vehicle area is obtained, the inflation controller disconnects the connection pipe between itself and the airbag to deflate the airbag; when the area controller obtains the airbag deflation end signal of the target vehicle area, it releases the restrictions on the drive motor and brake motor of the target vehicle area.

[0084] Reference Figure 4 As shown, in one embodiment, the area control system may further include: a switching assembly connected to the inflation controller; the switching assembly is a purely mechanical structural component for controlling the inflation controller to open or close, such as a pull cord.

[0085] In this case, the inflation controller is also used to inflate the airbag in response to a valid opening operation by the user on the target switch assembly; wherein the target switch assembly is a switch assembly in the same vehicle body area as the inflation controller; the valid opening operation includes: initiating at least a first number of activation operations on the switch assembly within a third time period.

[0086] In a specific embodiment, the switch assembly can be arranged in a dedicated recess in the center of the roof area in the front row of the vehicle, covered by a plastic cover. The plastic cover is engraved with characters indicating the location of the switch assembly to the user. The user can operate the switch assembly after removing the cover.

[0087] The switch assembly is connected to the gas generator switch on the inflation controller. The gas generator switch can be electrically opened and closed by the inflation controller, or it can be opened and closed by the switch assembly. To avoid accidental operation, at least the first activation operation of the switch assembly can be initiated within the third time interval to be considered a valid opening operation for the switch assembly.

[0088] Taking a pull cord as an example of a switch assembly, the pull cord is located in a dedicated pull cord recess in the center of the roof area in the front row of the vehicle. After the user removes the cover, the pull cord automatically hangs down. For example, the pull cord can be manually pulled continuously. Each pull causes the gas generator switch to slide down one latch position until the pull cord is pulled continuously at least the first number of times (e.g., 3 times) within a third time period. At this point, the gas generator switch slides down to an unlatched position, causing the gas generator to fall out.

[0089] If the space for the gas generator to explode is sufficient, gas will be generated immediately and quickly fill the airbag, generating buoyancy and causing the car to float.

[0090] In addition, if the rope is pulled fewer times in the third time period than the first time, it may be a mistake. In this case, the rope will automatically return to its original position.

[0091] The above-described embodiment of manual rescue based on switch components can provide users with a last resort for manual rescue in cases where the accident of a vehicle falling into water is serious and various functions of the vehicle cannot operate normally, thereby further improving the safety of the vehicle when it falls into water.

[0092] In summary, the vehicle submersion rescue system provided in this embodiment includes at least: a region controller and multiple region control systems for vehicle body areas; each region control system includes, but is not limited to: an inflation controller and an airbag connected to the inflation controller; wherein, there are multiple region controllers, and the inflation controllers in the multiple region control systems are connected to each of the multiple region controllers; or, there is one region controller, and the inflation controllers in the multiple region control systems are all connected to the region controller. The inflation controller is used to inflate the airbag when a vehicle submersion signal is received in a target vehicle body area; the target vehicle body area is the vehicle body area corresponding to the current inflation controller; the region controller is used to control the brake motor and drive motor of the target vehicle body area to stop output when a vehicle submersion signal is received in the target vehicle body area.

[0093] The rescue system provided by this solution features a zone control system configured for different vehicle body areas. Each vehicle body area can independently control the inflation of airbags and the output of the brake and drive motors, making rescue control more flexible and convenient. In particular, compared to general non-zoned overall control, this solution achieves superior control performance when the zone control systems of different vehicle body areas are used in combination. For any target vehicle body area, when the inflation controller receives a signal that the vehicle in its target area has fallen into water, it inflates the airbags in that target area, causing the airbags to expand rapidly. The inflated airbags increase the buoyancy of the vehicle in the water, slowing down the vehicle's sinking or making it float, buying time for rescue and reducing the difficulty of rescue. By controlling the brake and drive motors of the target vehicle body area to stop output through the zone controller, the safety of the vehicle when it falls into water can be improved, reducing the vehicle's kinetic energy and lowering the risk of injury to the occupants.

[0094] Furthermore, by providing a switch assembly connected to the inflation controller, a manual triggering option is available in addition to automatic triggering. Moreover, both automatic and manual triggering methods offer greater flexibility; automatic triggering is based on real-time pressure detected by a water pressure sensor to determine if the vehicle is submerged, automatically triggering the inflation controller to inflate the airbags; manual triggering, based on the switch assembly, allows the user to manually activate the inflation controller to inflate the airbags.
