[0026] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0028] In response to vehicle-falling-into-water accidents, the embodiments of the present disclosure provide a vehicle-falling-into-water rescue system and method. This solution can independently perform rescue control on each vehicle body area. For each vehicle body area, when the vehicle falls into water, the inflatable float (airbag for short) can be inflated through the inflation controller to increase the buoyancy of the vehicle in the water, so that the vehicle floats up or slows down its sinking, thereby buying time for rescue and reducing the difficulty of rescue; and the drive motor and brake motor can be controlled to stop output through the regional controller to improve the safety of the vehicle when it falls into water. For ease of understanding, the embodiments of the present disclosure are described in detail below.

[0029] Figure 1 and Figure 2 The schematic diagram of the architecture of a vehicle-falling-into-water rescue system provided by an embodiment of the present disclosure. The vehicle-falling-into-water rescue system may include: a zone controller and a zone control system for multiple vehicle body zones; each zone control system includes: an inflation controller and an airbag connected to the inflation controller.

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

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

[0032] In the above-mentioned vehicle-falling-into-water rescue system, the inflation controller is used to inflate the airbag when a vehicle-falling-into-water signal of a target vehicle body area is obtained; wherein the target vehicle body area is the vehicle body area corresponding to the current inflation controller; the area controller is used to control the brake motor and the drive motor of the target vehicle body area to stop output when a vehicle-falling-into-water signal of the target vehicle body area is obtained.

[0033] Possible ways to obtain the vehicle falling into water signal of the target vehicle body area include: the user actively submits the vehicle falling into water signal of the target vehicle body area through human-computer interaction; the real-time pressure is detected by the water pressure sensor installed in different vehicle body areas, and when the real-time water pressure is greater than the preset pressure threshold, the vehicle falling into water signal of the target vehicle body area where the water pressure sensor is located is generated; the driving image is collected by the camera, and the vehicle falling into water is determined by image recognition of the driving image and the vehicle falling into water signal of the target vehicle body area is generated; or, the vehicle falling into water signal of the target vehicle body area is generated based on the pressure of the water pressure sensor and the driving image of the camera at the same time. It can be understood that the above are only examples of obtaining the vehicle falling into water signal of the target vehicle body area, and are not limited here.

[0034] In this embodiment, when the inflation controller obtains the signal of the vehicle falling into water in the target vehicle body area, it can inflate the airbag connected to it. The inflation controller has a built-in independent power supply; the power supply is used to provide energy to the inflation controller when the vehicle is powered off, so that the inflation controller can inflate the airbag. In the case that various components of the vehicle cannot operate normally due to a water failure, the built-in independent power supply ensures that the inflation controller can still control the inflation of the airbag.

[0035] The inflation controller has a built-in gas generator, which can generate a large amount of gas by igniting the gas generator with electric current. The generated gas is quickly filled into the airbag through the pipe connecting the inflation controller and the airbag, causing the airbag to expand and deploy rapidly. The airbag filled with gas increases the buoyancy of the vehicle in the water, slowing down the vehicle's sinking or making the vehicle float, buying time for rescue and reducing the difficulty of rescue.

[0036] In addition, when the regional controller obtains the signal that the vehicle falls into water in the target body area, it can control the brake motor in the target body area to brake and control the drive motor to stop output within a certain period of time (such as 3 seconds) to lock the wheels. This can improve the safety of the vehicle when it falls into water, reduce the kinetic energy of the vehicle, and reduce the risk of injury to people in the vehicle.

[0037] In some embodiments, the regional control systems of the plurality of vehicle body regions include, for example, a regional control system of the front region of the vehicle body and a regional control system of the rear region of the vehicle body. Alternatively, in order to achieve more detailed control, the regional control systems of the plurality of vehicle body regions include, for example, a regional control system of the left front region of the vehicle body, a regional control system of the right front region of the vehicle body, a regional control system of the left rear region of the vehicle body, and a regional control system of the right rear region of the vehicle body.

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

[0040] The material of the airbag in the above embodiment can be made of special rubber, which has the characteristics of high strength, wear resistance and good air tightness.

[0041] In this embodiment, different sizes and numbers of airbags can be installed on vehicles according to the weight, volume and load mass of different vehicle models, so that the buoyancy generated by the airbags after they are inflated and fully deployed can lift the vehicle and avoid the waste of resources caused by using too large or too many airbags on smaller vehicles. The buoyancy design standard of a single airbag is as follows:

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

[0043] The above-mentioned airbags can be applied to, for example: cars with a curb weight of 1.2-1.8 tons and a load weight of 0.35-0.5 tons, SUVs with a curb weight of 1.5-2.5 tons and a load weight of 0.35-0.5 tons, MPVs with a curb weight of 1.8-2.2 tons and a load weight of 0.5-0.8 tons, etc., which are not listed here one by one.

[0044] In actual scenarios, the airbags can be installed at the wheel fenders of the four wheels, and when the airbags are deployed and filled with gas, the fully deployed airbags can wrap the wheels. Alternatively, the airbags can be installed at the bottom of the vehicle and the left and right sides of the vehicle, and the number of airbags installed at the bottom and the left and right sides is at least one.

[0045] On the basis of the above embodiments, the regional control system may further include: a water pressure sensor connected to the regional controller and the inflation controller respectively. Based on this, in the rescue system for a vehicle falling into water, the regional control system of 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, the regional controller and the inflation controller are connected to each other, the airbag is connected to the inflation controller, and the brake motor and the drive motor are both connected to the regional controller.

[0046] The water pressure sensor in this embodiment is used to collect real-time pressure and transmit the real-time pressure to the zone controller and the inflation controller.

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

[0048] When a vehicle falls into water, the water pressure sensor can measure the pressure generated by the collected water, and the pressure changes with the water depth. The depth of the vehicle entering the water can be accurately identified based on the collected pressure.

[0049] for Figure 2 In the rescue system shown in FIG. 1 , the same zone controller is connected to water pressure sensors in multiple vehicle body zones. Figure 1 In the rescue system shown, in the same vehicle body area, the area controller is connected to at least one water pressure sensor. For example, in the area control system in the front area 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 the real-time pressure it collects to the zone controller. In this case, the zone controller is also used to generate a vehicle-under-water signal 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 time (e.g., 5 seconds), and send the vehicle-under-water signal to the inflation controller. The real-time pressure of the at least one water pressure sensor can be Figure 2 The real-time pressure of the water pressure sensor of at least one vehicle body area, or Figure 1 The real-time pressure of at least one water pressure sensor in the same vehicle body area.

[0051] Specifically, the zone controller comprehensively determines whether 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 first pressure threshold represents the minimum pressure to which the vehicle is subjected when in water. If so, it can be determined that a vehicle-overwater accident has occurred, and a vehicle-overwater signal is generated, and the vehicle-overwater signal is synchronized to the inflation controller. In this embodiment, based on the real-time pressures of multiple water pressure sensors and taking into account the duration, it is possible to more accurately determine whether a vehicle-overwater accident has actually occurred, and the generated vehicle-overwater signal is more accurate to avoid misjudgment.

[0052] Alternatively, in another embodiment, the water pressure sensor, inflation controller and airbag corresponding to the same vehicle body area are connected in sequence, for example, the left front water pressure sensor, the first inflation controller and the left front airbag are connected in sequence, and 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 falls into water, and to control the inflation of the left front airbag in the event of falling into water. In this case, the inflation controller is also used to generate a vehicle falling into water signal when the vehicle falling into water signal sent by the area controller is not received and the real-time pressure is greater than the first pressure threshold and lasts for a second time period; wherein the second time period is greater than the first time period.

[0053] In the scenario where a vehicle falls into water, since the inflation controller directly inflates the airbag, its waterproof level must be high to ensure that it can work normally in water. At the same time, considering the manufacturing cost, the waterproof level of components such as the zone controller is generally lower than that of the inflation controller. Based on this, when a vehicle falls into water, the zone controller and other components may be damaged, so the zone controller cannot send a vehicle fall-in-water signal to the inflation controller.

[0054] To address this problem, the water pressure sensor can directly transmit the real-time pressure it collects to the inflation controller, and the inflation controller determines whether the real-time pressure of the water pressure sensor is greater than the preset first pressure threshold and lasts for a second time period. The second time period is longer than the first time period. On the one hand, the vehicle falling into water signal synchronized by the regional controller can be waited for within the second time period. If the vehicle falling into water signal sent by the regional controller cannot be waited for, the inflation controller itself determines whether a vehicle falling into water accident has occurred based on the real-time pressure. On the other hand, compared with the amount of pressure data obtained by the regional controller, the inflation controller is only connected to the water pressure sensor in the target vehicle body area where it is located, and the amount of pressure that can be obtained is less, so a longer second time period is used to avoid misjudgment of falling into water accidents.

[0055] Furthermore, when the inflation controller does not receive the vehicle falling into water signal sent by the zone controller and the real-time pressure is greater than the first pressure threshold and lasts for the second time period, the inflation controller generates a vehicle falling into water signal.

[0056] Therefore, the above embodiment can generate a vehicle-falling-into-water signal by the regional controller according to the real-time water pressure of at least one water pressure sensor and the first duration. This method is more accurate in generating a vehicle-falling-into-water signal and can avoid misjudgment. Alternatively, the above embodiment can also generate a vehicle-falling-into-water signal by the inflation controller according to the real-time water pressure and the second duration. This method can make up for the problem of damage to the regional controller due to immersion in water and also ensure the accuracy of generating a vehicle-falling-into-water signal.

[0057] In the above embodiments, the inflation controller determines the vehicle falling into water signal according to the real-time water pressure measured by the water pressure sensor, and then inflates the airbag; and the zone controller determines the vehicle falling into water signal according to the real-time water pressure measured by the water pressure sensor, and then controls the brake motor and the drive motor to stop output. This solution uses a precise water pressure sensor and an inflation controller for triggering the airbag to accurately identify the vehicle falling into water signal and trigger the inflation of the airbag in time when the vehicle falls into water, thereby improving the reliability and response speed of the system and reducing the difficulty of rescue; at the same time, by controlling the brake motor and the drive motor to stop output, the safety of the vehicle falling into water is improved.

[0058] In this embodiment, the vehicle falling into water rescue system may further include: a central computing unit connected to the regional controller and a network controller connected to the central computing unit. Figure 1 As shown, the rescue system for a vehicle falling into water may include: a central computing unit, a networked 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. Figure 2 As shown, the rescue system for a vehicle falling into water may include: a central computing unit, a networked controller, a regional controller and multiple regional control systems; the multiple regional control systems are commonly 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 the vehicle status information sent by the regional controller and send an alarm instruction to the network controller according to the vehicle status information; wherein the vehicle status information includes but is not limited to: a vehicle falling into water signal, real-time water pressure, an airbag deployment signal, an operating state of a brake motor, and an operating state of a drive motor;

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

[0061] In a specific embodiment, the area controller corresponding to the target vehicle body area where the vehicle falls into water sends a vehicle falling into water signal to the central computing unit; the central computing unit determines whether the rescue condition is met to send a rescue platform according to the vehicle falling into water signal and other vehicle status information; the condition may include one or more of the following:

[0062] a) receiving vehicle falling-into-water signals from at least N1 (e.g., N1=2) vehicle body regions sent by the regional controller; this situation indicates that multiple vehicle body regions have fallen into water, which is quite dangerous and requires intervention of external rescue forces;

[0063] b) The real-time pressure is greater than the preset first pressure threshold and continues to increase; this situation indicates that the vehicle is continuing to sink, which is quite dangerous and requires the intervention of external rescue forces;

[0064] c) receiving the deployment signals of at least N2 airbags; this situation is similar to the above situation a);

[0065] d) The operating state of the brake motor is limited operation and / or the operating state of the drive motor is limited 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 networked controller. The networked controller sends a rescue alarm message to the rescue platform based on the alarm command. After the rescue platform receives the rescue alarm message, the customer service staff can communicate with the car owner to ask about the car owner's current situation and whether rescue is needed. If the car owner does not respond or needs rescue, the local rescue department will be contacted to organize rescue based on the current vehicle's networked positioning information.

[0067] In addition, in this embodiment, after the vehicle escapes from the water dilemma, the inflation controller is further used to disconnect the connection pipe between the airbag and the airbag when an airbag closing signal of the target vehicle body area is obtained, so as to deflate the airbag; wherein the airbag closing signal includes: a closing signal initiated by the user, or a closing signal generated when the real-time water pressure collected by the water pressure sensor is less than the preset second pressure threshold and lasts for a fourth time period;

[0068] The area controller is also used to release the restrictions on the drive motor and brake motor of the target vehicle body area when an airbag deflation end signal is obtained; wherein the airbag deflation end signal includes: an end signal initiated by the user, or an end signal generated after the fifth time period of generating the airbag closing signal.

[0069] In a specific embodiment, the shutdown signal may be obtained through the following examples.

[0070] Example 1: After the vehicle is out of the water, the user can actively initiate a shutdown signal indicating that the airbag inflation in the target vehicle body area is turned off.

[0071] Example 2: The water pressure sensor collects the real-time water pressure of the target vehicle body area; the area controller and / or the inflation controller receives the real-time water pressure and determines whether the real-time water pressure is lower than a preset second pressure threshold, the second pressure threshold is, for example, 2950 Pa, which is the pressure at which the vehicle can escape from the water failure. If the real-time water pressure is lower than the preset second pressure threshold and lasts for a fourth time period, a shutdown signal is generated.

[0072] Example three, the water pressure sensor collects the real-time water pressure of the target body area of ​​the vehicle; the area controller and / or the inflation controller receives the real-time water pressure and determines whether the real-time water pressure is lower than the preset second pressure threshold. If the real-time water pressure is lower than the preset second pressure threshold and lasts for a fourth time period, a quasi-closing signal is generated and sent to the central computing unit. The central computing unit generates a selection prompt message of whether to turn off the inflation controller based on the quasi-closing signal; for example, the vehicle microphone is controlled to voice play the selection prompt message of whether to turn off the inflation controller based on the quasi-closing signal, and the central control display screen is controlled to display the selection prompt message of whether to turn off the inflation controller based on the quasi-closing signal. After receiving the user's selection result of turning off the inflation controller, the central computing unit generates a final closing signal.

[0073] When the airbag closing signal of the target vehicle body area is obtained, the inflation controller disconnects the connection pipe between the airbag and the airbag to deflate the airbag.

[0074] After the airbag is deflated, the user may actively initiate an airbag deflation completion signal indicating that the airbag deflation is complete. Alternatively, the airbag deflation completion signal may be generated after the fifth time period of generating the airbag closing signal; the fifth time period is the time period required for the airbag to be completely deflated after actual testing; the airbag starts to be deflated when the airbag closing signal is generated, and after the deflation reaches the fifth time period, it can be considered that the airbag has been deflated, so the airbag deflation completion signal is generated.

[0075] Furthermore, when the area controller obtains the airbag deflation completion signal, it releases the restrictions on the drive motor and the brake motor in the target vehicle body area, such as releasing the torque output restriction on the drive motor and releasing the brake motor.

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

[0077] (1) Collect real-time pressure through 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 period of time, the zone controller generates a vehicle-under-water signal for the target vehicle body area and sends the vehicle-under-water signal to the inflation controller; or, when the real-time pressure of the inflation controller is greater than the first pressure threshold and lasts for a second period of time, the inflation controller generates a vehicle-under-water signal for the target vehicle body area.

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

[0080] Specifically, water pressure sensors, inflation controllers and airbags are installed at the four corners of the vehicle bottom, front, back, left and right respectively; the water pressure sensor can collect the pressure exerted by water on the vehicle, and the pressure increases with the increase of water depth, thereby accurately measuring the change of water pressure. The inflation controller is connected to the water pressure sensor. When the real-time pressure is greater than the preset first pressure threshold, the inflation controller is triggered to inflate the float bag. The airbag filled with gas generates buoyancy to prevent the vehicle from sinking quickly, buy more escape time for the people in the vehicle, and improve the safety of the vehicle when it falls into the water.

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

[0082] (5) The regional controller sends a vehicle-falling-into-water signal to the central computing unit; the central computing unit receives the vehicle status information, which includes: the vehicle-falling-into-water signal, real-time water pressure, the airbag deployment signal, the operating status of the brake motor, and the operating status of the drive motor. Then, the central computing unit sends an alarm instruction to the networked controller according to the vehicle status information; the networked controller sends rescue alarm information to the rescue platform according to the alarm instruction.

[0083] (6) When the airbag closing signal of the target vehicle body area is obtained, the inflation controller disconnects the connection pipe between the inflation controller and the airbag to deflate the airbag; when the area controller obtains the airbag deflation completion signal of the target vehicle body area, the restriction on the drive motor and the brake motor of the target vehicle body area is released.

[0084] Reference Figure 4 As shown, in one embodiment, the regional control system may further include: a switch component connected to the inflation controller; the switch component is a purely mechanical structural component for controlling the inflation controller to be turned on or off, such as a pull rope.

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

[0086] In a specific embodiment, the switch assembly can be arranged in a dedicated groove in the center of the roof area of ​​the front row of the vehicle and covered with a plastic cover. The characters of the switch assembly are engraved on the plastic cover to remind the user of the location of the switch assembly. After the user removes the cover, the switch assembly can be operated.

[0087] The switch assembly is connected to the switch of the gas generating agent on the inflation controller, and the switch of the gas generating agent can be electrically opened and slid by the inflation controller, or can be opened and slid by the switch assembly. In order to avoid misoperation, at least the first number of start operations can be initiated on the switch assembly within the third time period, which is regarded as an effective start operation for the switch assembly.

[0088] Taking the pull cord as an example of a switch component, the pull cord is arranged in a dedicated pull cord groove in the center of the roof area of ​​the front row of the vehicle. After the user removes the cover plate, the pull cord automatically falls down. For example, the pull cord can be pulled manually and continuously, and each time the pull cord is pulled, the switch of the gas generator slides down a buckle position, until the pull cord is pulled continuously for at least the first number of times (such as 3 times) within the third time period, and the switch of the gas generator slides down to the non-buckle position in turn, so that the gas generator slides down.

[0089] When the explosion space of the gas generator is met, gas is generated immediately and quickly fills the airbag, generating buoyancy and causing the car to float.

[0090] In addition, if the number of times the pull cord is pulled within the third time period is less than the first number, it may be an incorrect operation. In this case, the pull cord will automatically return to its original position.

[0091] The above-mentioned embodiment of manually triggering rescue based on the switch component can provide users with the last guarantee of manual rescue when the car falls into water in a serious accident 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 rescue system for vehicles falling into water provided by the embodiments of the present disclosure at least includes: a zone controller and a zone control system for multiple vehicle body areas; each zone control system includes but is not limited to: an inflation controller, an airbag connected to the inflation controller; wherein there are multiple zone controllers, and the inflation controllers in the multiple zone control systems are connected one by one to the multiple zone controllers; or, there is one zone controller, and the inflation controllers in the multiple zone control systems are all connected to the zone controller. The inflation controller is used to inflate the airbag when a vehicle falling into water signal of a target vehicle body area is obtained; the target vehicle body area is the vehicle body area corresponding to the current inflation controller; the zone controller is used to control the brake motor and the drive motor of the target vehicle body area to stop output when a vehicle falling into water signal of the target vehicle body area is obtained.

[0093] The rescue system provided by this solution is configured with a regional control system for each vehicle body area. Each vehicle body area can independently realize the inflation control of the airbag and the output control of the brake motor and the drive motor, making the rescue control more flexible and convenient. In particular, compared with the general non-regional overall control, this solution can achieve better control effects when the regional control systems of different vehicle body areas are used in combination. For any of the target vehicle body areas, when the inflation controller obtains the signal that the vehicle in the target vehicle body area falls into the water, the airbag of the target vehicle body area is inflated by the inflation controller, which can make the airbag expand and deploy rapidly. The airbag filled with gas increases the buoyancy of the vehicle in the water, slows down the sinking of the vehicle or makes the vehicle float, buys time for rescue and reduces the difficulty of rescue. The brake motor and drive motor of the target vehicle body area are controlled to stop output by the regional controller, which can improve the safety of the vehicle when it falls into the water, reduce the kinetic energy of the vehicle, and reduce the risk of injury to people in the vehicle.

[0094] Furthermore, by providing a switch assembly connected to the inflation controller, a manual rescue solution can be provided in addition to the automatic rescue. Moreover, the two methods of automatic rescue and manual rescue are more flexible; the automatic rescue is based on the real-time pressure sensed by the water pressure sensor, determines the vehicle falling into the water signal, and automatically triggers the inflation controller to inflate the airbag; the manual rescue is based on the switch assembly, so that the user can manually trigger the switch assembly and manually trigger the inflation controller to inflate the airbag.

[0102] Alternatively, when the zone controller does not generate a vehicle-falling-into-water signal and the real-time pressure is greater than the first pressure threshold and lasts for a second time period, a vehicle-falling-into-water signal is generated by the inflation controller; wherein the second time period is greater than the first time period.
