Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, device, vehicle, and medium for automobile protection based on a waterproof safety system. Background Technology

[0002] With my country's rapid economic development, people's living standards have improved significantly. Car ownership is increasing, evolving from traditional gasoline vehicles to new energy vehicles, offering consumers more choices and making cars more intelligent. This has also led to higher demands for vehicle safety. Airbags have become standard equipment, and battery fire prevention is a key research area; therefore, safety is often a crucial criterion for consumers.

[0003] Currently, global warming is leading to more severe weather, such as frequent urban torrential rains, which can cause roads to be flooded and cars to become unusable, resulting in significant expenses for users. Furthermore, due to the diversity of vehicles, different driving habits, and road conditions, car accidents involving falling into water are on the rise. Drivers may be unable to open the car doors to escape, with only a few seconds to do so. Therefore, adding waterproof airbags to protect people and vehicles is essential to address scenarios involving falling into or being submerged in water. Currently, most cars are unable to withstand heavy rain, high tides, and falling into water; incidents of cars failing to navigate underpasses and becoming stuck in the water are not uncommon.

[0004] In related technologies, an air cushion assembly hidden inside the vehicle body shell and a collision sensor installed inside the vehicle body shell are used. A power supply and a manual control switch are fixed on the roof of the vehicle. The system determines whether to activate the flotation device based on the impact force threshold of the impact sensor, thereby enhancing the vehicle's anti-collision capability in accidents and its ability to float in water when the vehicle falls into the water.

[0005] However, considering the small volume of the vehicle's side panels, it is difficult to conceal the air cushion components within the vehicle's outer shell. In the event of a collision, the concealed air cushion components are difficult to deploy because the doors, frame, and crash beams all use steel structures. Furthermore, since the position and size of sensors affect collision data, there is a risk that the air cushion components in related technologies may not be able to deploy. In addition, the external sensors around the vehicle are easily damaged by external impacts or minor collisions, which could cause the devices to deploy on their own or be destroyed. Due to the unpredictability of collision accidents, the air cushion may have already deployed during the first land collision, and may have deflated by the time it enters the water. Moreover, deployment upon every impact could impact the interior of the vehicle, creating many safety hazards. Most importantly, most collision accidents are unrelated to falling into water, making it impossible to distinguish the specific scenario of falling into water.

[0006] Therefore, the solutions in the relevant technologies cannot guarantee the safety of vehicles when they encounter collisions or fall into water, and this needs to be addressed urgently. Summary of the Invention

[0007] This application provides a vehicle protection method, device, vehicle, and medium based on a safe waterproof system to solve problems in related technologies, such as unreasonable installation of air cushion components and sensors, which cannot guarantee the safety of vehicles in water-related environments. The system is structurally safe, easy to maintain, and has flexible and diverse opening methods, enabling vehicles to flexibly cope with scenarios such as heavy rain, high tide, and falling into water.

[0008] The first aspect of this application provides a vehicle protection method based on a waterproof safety system, comprising the following steps:

[0011] If the current water depth at any vehicle body location is greater than the preset depth, and the duration for which the current water depth at any vehicle body location is greater than the preset depth is greater than the preset duration, and the current vehicle speed is less than the preset vehicle speed, then a waterproofing strategy for the vehicle is determined based on the current water depth at each vehicle body location, and waterproofing control of the vehicle is performed based on the waterproofing strategy.

[0029] A second aspect of this application provides a vehicle protection device based on a waterproof safety system, comprising:

[0030] The acquisition module is used to acquire the vehicle's current speed and the current pressure at at least one body position.

[0031] The judgment module is used to calculate the current water depth of each vehicle body position based on the current pressure of the at least one vehicle body position, and to determine whether there is any vehicle body position where the current water depth is greater than a preset depth, and the duration for which the current water depth of any vehicle body position is greater than the preset depth is greater than a preset duration, and the current vehicle speed is less than a preset vehicle speed.

[0032] The control module is configured to determine a waterproofing strategy for the vehicle based on the current water depth at each vehicle body location, and to perform waterproofing control on the vehicle based on the waterproofing strategy, when the current water depth at any vehicle body location is greater than the preset depth, the duration for which the current water depth at any vehicle body location is greater than the preset depth is greater than the preset duration, and the current vehicle speed is less than the preset vehicle speed.

[0033] Optionally, in some embodiments, the control module is specifically used for:

[0034] Obtain the vehicle body angle;

[0035] Determine whether the water depth at the head is greater than the water depth in the middle, and whether the water depth in the middle is greater than the water depth at the tail.

[0036] When the water depth at the head is greater than the water depth in the middle, and the water depth in the middle is greater than the water depth at the tail, the vehicle's waterproofing strategy is to first deploy the front airbag, and then deploy the rear airbag after a second preset time period based on the vehicle's angle.

[0037] Determine whether the water depth at the head is less than the water depth in the middle section, and whether the water depth in the middle section is less than the water depth at the tail section;

[0038] When the water depth at the head is less than the water depth in the middle, and the water depth in the middle is less than the water depth at the tail, the vehicle's waterproofing strategy is to first activate the rear airbag, and then activate the front airbag after a third preset time period based on the vehicle body angle.

[0039] Determine whether the head water depth is equal to the middle water depth, and whether the middle water depth is equal to the tail water depth;

[0040] When the water depth at the head is equal to the water depth at the middle, and the water depth at the middle is equal to the water depth at the tail, the vehicle's waterproofing strategy is to simultaneously deploy the front airbag and the rear airbag based on the vehicle's body angle.

[0041] Optionally, in some embodiments, before acquiring the current vehicle speed and the current pressure at the at least one vehicle body position, the acquisition module is further configured to:

[0042] Obtain the maximum water depth pressure of the vehicle;

[0046] Determine the opening mode of the vehicle;

[0047] The opening modes include closed mode, manual mode, and automatic mode.

[0048] Optionally, in some embodiments, the control module is further configured to:

[0049] When the opening mode is manual mode, it is not necessary to obtain the current vehicle speed and the current pressure at at least one vehicle body position, and the vehicle is waterproofed based on a preset emergency protection strategy.

[0050] A third aspect of this application provides a vehicle, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the vehicle protection method based on a waterproof safety system as described in the above embodiments.

[0051] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which is executed by a processor to implement the vehicle protection method based on a waterproof system as described in the above embodiments.

[0052] Therefore, this application obtains the vehicle's current speed and the current pressure at at least one vehicle body position. Based on the current pressure at at least one vehicle body position, it calculates the current water depth at each vehicle body position. If the current water depth at any vehicle body position is greater than a preset depth, and the duration of this excess water depth is greater than a preset duration, while the current vehicle speed is less than a preset speed, then a waterproofing strategy for the vehicle is determined based on the current water depth at each vehicle body position, and waterproofing control is applied to the vehicle according to this strategy. This solves the problems in related technologies where improper installation of the air cushion components and sensors fails to guarantee vehicle safety in submerged environments. The structure is safe, maintenance is convenient, and the opening methods are flexible and diverse, allowing the vehicle to flexibly cope with scenarios such as heavy rain, high tides, and submersion.

[0066] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0067] The following description, with reference to the accompanying drawings, outlines a vehicle protection method, apparatus, vehicle, and medium based on a waterproof safety system, according to embodiments of this application. Addressing the issue mentioned in the background art where improper installation of air cushion components and sensors fails to guarantee vehicle safety in a submerged environment, this application provides a vehicle protection method based on a waterproof safety system. In this method, the current vehicle speed and the current pressure at at least one vehicle body location are obtained. Based on the current pressure at each vehicle body location, the current water depth at each location is calculated, and it is determined whether any vehicle body location has a current water depth greater than a preset depth, and the duration of this excess water depth is greater than a preset duration, while the current vehicle speed is less than a preset speed. If any vehicle body location has a current water depth greater than a preset depth, and the duration of this excess water depth is greater than a preset duration, while the current vehicle speed is less than a preset speed, then a waterproofing strategy for the vehicle is determined based on the current water depth at each vehicle body location, and waterproofing control of the vehicle is implemented according to this strategy. This solves the problems in related technologies, such as the unreasonable installation of air cushion components and sensors, which cannot guarantee the safety of vehicles in water-related environments. The structure is safe, easy to maintain, and has flexible and diverse opening methods, enabling vehicles to flexibly cope with scenarios such as heavy rain, high tide, and falling into water.

[0068] Specifically, Figure 1 This is a schematic flowchart illustrating a vehicle protection method based on a waterproof safety system, provided in an embodiment of this application.

[0069] like Figure 1 As shown, this vehicle protection method based on a waterproof safety system includes the following steps:

[0070] In step S101, the current vehicle speed and the current pressure at at least one vehicle body position are obtained.

[0071] In this application embodiment, the vehicle body positions include the front position, the middle position of the vehicle body, and the parking space position. The pressure in this application embodiment refers to water pressure.

[0072] In some embodiments, the current vehicle speed can be obtained by registering a vehicle infotainment system service for monitoring. The current pressure at at least one location on the vehicle body can be obtained using a water pressure sensor.

[0073] Specifically, embodiments of this application provide a safe waterproof system. Figure 2 This is a schematic diagram of a secure waterproof system according to the first specific embodiment of this application. Figure 2 In the diagram, 1 represents multiple water pressure sensors, and 2 represents an air cushion. Figure 2 The vehicle chassis water pressure sensor and a single air cushion structure were showcased. Figure 3 This is a schematic diagram of a secure waterproof system according to a second specific embodiment of this application. Figure 3The vehicle chassis water pressure sensor and multiple air cushion structures were showcased. Figure 4 This is a schematic diagram of a secure waterproof system according to a third specific embodiment of this application. Figure 4 A simplified diagram illustrating the embedded design for collision and rain protection of the water pressure sensor in the vehicle chassis.

[0074] like Figures 2-4 As shown, the safety and waterproof system of this application embodiment includes: a water pressure sensor under the vehicle, an air cushion system under the vehicle, an emergency start button inside the vehicle, an in-vehicle decision control unit, and a mobile phone control APP (Application).

[0075] The system includes underbody water pressure sensors located at the front, middle, and rear of the chassis to acquire the current pressure at at least one location on the vehicle body; an underbody air cushion system located on the chassis, comprising an air cushion, a gas generator, an air cushion container, and a container hook; an in-vehicle emergency start button located inside the cabin to trigger manual deployment of the air cushion; an in-vehicle decision control unit located inside the vehicle, connected via circuitry to the underbody water pressure sensors, the underbody air cushion system, and the in-vehicle emergency start button; and a mobile control app that can establish a network connection with the vehicle's infotainment system for remote control.

[0076] Furthermore, the air cushion in this embodiment can be detachable, with one air cushion container at the front and one at the rear of the chassis, each containing a gas generator, and connected to the vehicle's decision control unit via circuitry. Alternatively, the air cushion in this embodiment can be integral, contained within the chassis air cushion container, and its shape can be semi-enclosed, except for the tires and exhaust pipe. In this embodiment, the tires and exhaust pipe are designed to be unenclosed, thus allowing the car to float on water and control its movement on the water via the accelerator (electric switch) and steering wheel. Additionally, if the air cushion in this embodiment is designed to be lower than the tire height and made of a relatively rigid material (with a controllable shape), it can also be used on land after deployment.

[0077] Therefore, after a car falls into the water, the air cushion design according to the embodiments of this application can control the car to drive from the water to the shore, and on a slope where conditions permit, it can control the car to drive directly to land, enabling the vehicle to flexibly cope with scenarios such as heavy rain, high tide, and falling into the water.

[0078] The air cushion container in this application embodiment can be a one-piece rectangular shape. Those skilled in the art can place it on the vehicle chassis according to the vehicle body length. The air cushion container can be set on the vehicle chassis, one at the front and one at the rear. Specifically, it can be located at the middle of the front and rear wheels respectively.

[0079] The vehicle underbody air cushion system of this application embodiment uses an inflation device that conforms to the air cushion industry standard. The air cushion is folded and contained within an air cushion container, with the inflation device mounted in the upper part of the container and connected to the vehicle's infotainment system via electrical circuitry. The air cushion container is secured to the chassis with clips around its perimeter. The air cushion container clips receive signals from the vehicle's infotainment system and can be folded up to detach the air cushion container.

[0080] It should be noted that in this embodiment of the application, the air cushion container is fixed to the vehicle body by a grab hook. The air cushion container contains an unopened air cushion. When the air cushion is opened, the container cover automatically opens upon receiving an instruction. The air cushion container can retract the grab hook and detach from the entire air cushion container and air cushion by receiving a detachment instruction.

[0081] In some embodiments, this application provides multiple water pressure sensors located at the bottom of the vehicle, specifically at the front, middle, and rear of the vehicle floor. These sensors are connected to the vehicle's infotainment system via circuitry. The water pressure sensors can be installed in the chassis's anti-collision recesses to effectively prevent damage from impacts, scratches, rain, and other abnormal conditions.

[0082] As can be seen from the above embodiments, the air cushion container and water pressure sensor of the safety and waterproof system of this application embodiment are installed on the chassis, which will not cause any damage to the vehicle body structure. Moreover, the water pressure sensor is set in the chassis groove to prevent damage from impacts, human error, etc. The entire air cushion container of this safety and waterproof system can be sealed like a battery, which is convenient for installation, removal, and replacement.

[0083] In step S102, the current water depth of each vehicle body position is calculated based on the current pressure at at least one vehicle body position, and it is determined whether there is a current water depth at any vehicle body position that is greater than a preset depth, and the duration for which the current water depth at any vehicle body position is greater than the preset depth is greater than the preset duration, and the current vehicle speed is less than the preset vehicle speed.

[0084] It is understood that the in-vehicle decision control unit in this application embodiment is the brain of the entire air cushion system, used to collect water pressure sensor data, implement the air cushion deployment algorithm, and record the air cushion mode. This application considers that the water pressure parameters of sensors in three parts of the vehicle can determine the vehicle's tilt; therefore, an air cushion deployment algorithm is designed to determine the priority order for deploying the air cushion.

[0085] Optionally, in some embodiments, before obtaining the vehicle's current speed and the current pressure at at least one vehicle body position, the method further includes: determining the vehicle's opening mode; wherein the opening mode includes a closing mode, a manual mode, and an automatic mode.

[0086] In this embodiment of the application, the closing mode is disabled when automatically opened and disabled when manually opened; the manual mode is disabled when automatically opened and enabled when manually opened; the automatic mode is enabled when automatically opened and enabled when manually opened.

[0087] Optionally, in some embodiments, before obtaining the vehicle's current speed and the current pressure at at least one vehicle body position, the method further includes: obtaining the vehicle's maximum water depth pressure; determining whether the vehicle meets preset protection conditions based on the maximum water depth pressure; if the vehicle does not meet the preset protection conditions, then there is no need to perform waterproofing control on the vehicle.

[0088] Understandably, before implementing waterproofing control for a vehicle, it is necessary to determine whether the vehicle requires waterproofing protection to differentiate between specific water-fall scenarios and prevent uncontrollable dangers caused by the arbitrary deployment of airbags in other accidents. Therefore, this application proposes preset protection conditions; if the vehicle does not meet these preset protection conditions, waterproofing control is not required.

[0089] Specifically, this application embodiment requires obtaining the maximum water depth pressure p of the vehicle.

[0090] p = ρgh;

[0091] Where p is pressure, ρ is liquid density (the density of water is 1×10^3 kg / m^3), g is gravitational acceleration (taken as 9.8 N / kg), and h is taken as 2 m.

[0092] Furthermore, based on the maximum water depth pressure p, abnormal scenarios such as filter impacts are considered.

[0093] Furthermore, after determining that the current vehicle needs waterproofing protection, this embodiment of the application needs to calculate the current water depth at each vehicle body location based on the current pressure at at least one vehicle body location, and determine the vehicle's waterproofing strategy based on the current water depth at any vehicle body location.

[0094] Specifically, the formula for calculating the water depth h in this application embodiment is as follows:

[0095] h = p / (ρg);

[0096] Where p is pressure, ρ is liquid density (the density of water is 1×10^3 kg / m^3), g is gravitational acceleration (taken as 9.8 N / kg), and h is the height from the pressure point to the liquid surface.

[0097] The preset depth in this embodiment is 15cm, and the preset duration is 3s. Under the automatic opening algorithm, the measured water depth will increase as the vehicle body sinks. To filter out normal scenarios such as rain and car washing, this embodiment sets a waiting time of 3s.

[0098] In addition, the vehicle speed in the water will not exceed 19 km / h. In order to prevent the high-speed deployment of the air cushion from causing uncertainty to the user, the vehicle speed is set not to exceed 19 km / h under the automatic deployment algorithm.

[0099] Therefore, in the automatic opening algorithm of this application embodiment, it is necessary to first calculate the current water depth of each vehicle body position based on the current pressure of at least one vehicle body position, namely the water depth at the front, middle and rear of the vehicle body, and determine whether there is any vehicle body position where the current water depth is greater than 15cm, and the duration of the current water depth at any vehicle body position being greater than 15cm is greater than 3s, and the current vehicle speed is less than 19km / h.

[0100] In step S103, if the current water depth at any vehicle body position is greater than a preset depth, and the duration for which the current water depth at any vehicle body position is greater than the preset depth is greater than a preset duration, and the current vehicle speed is less than a preset vehicle speed, then the vehicle's waterproofing strategy is determined based on the current water depth at each vehicle body position, and the vehicle is waterproofed according to the waterproofing strategy.

[0101] Specifically, if the current water depth at any vehicle body location is greater than 15cm, and the duration of the current water depth at any vehicle body location being greater than 15cm is greater than 3s, and the current vehicle speed is less than 19km / h, then the vehicle's waterproofing strategy is determined based on the current water depth at each vehicle body location.

[0102] Optionally, in some embodiments, the vehicle's waterproofing strategy is determined based on the current water depth at each vehicle body position, including: obtaining the vehicle's body angle; determining whether the head water depth is greater than the middle water depth, and whether the middle water depth is greater than the tail water depth; if the head water depth is greater than the middle water depth, and the middle water depth is greater than the tail water depth, then the vehicle's waterproofing strategy is to first activate the front airbag, and then activate the rear airbag after a second preset time period based on the vehicle body angle; determining whether the head water depth is less than the middle water depth, and whether the middle water depth is less than the tail water depth; if the head water depth is less than the middle water depth, and the middle water depth is less than the tail water depth, then the vehicle's waterproofing strategy is to first activate the rear airbag, and then activate the front airbag after a third preset time period based on the vehicle body angle; determining whether the head water depth is equal to the middle water depth, and whether the middle water depth is equal to the tail water depth; if the head water depth is equal to the middle water depth, and the middle water depth is equal to the tail water depth, then the vehicle's waterproofing strategy is to simultaneously activate both the front and rear airbags based on the vehicle body angle.

[0103] In this embodiment of the application, the second preset duration is 2s and the third preset duration is 2s.

[0104] It is understood that the water pressure parameters of the sensors in the three locations of this application embodiment reflect the vehicle body tilt, and thus the priority order of opening the air cushion can be determined according to the vehicle body tilt. Therefore, this application embodiment needs to first obtain the vehicle body angle and then perform waterproofing control on the vehicle based on the vehicle body angle.

[0105] In some cases, the water depth at the front of the vehicle is greater than the water depth in the middle of the vehicle, which is greater than the water depth at the rear of the vehicle. In this case, the waterproofing strategy of the vehicle in this application embodiment is to correct the vehicle body based on the vehicle body angle, prioritize the opening of the front airbag, and open the rear airbag after 2 seconds.

[0106] In some cases, the water depth at the front of the vehicle is less than the water depth in the middle, which is less than the water depth at the rear. In this case, the waterproofing strategy of the vehicle in this embodiment is to correct the vehicle body based on the vehicle body angle, prioritize the activation of the rear airbag, and activate the front airbag after 2 seconds.

[0107] In other cases, the water depth at the front of the vehicle equals the water depth in the middle of the vehicle equals the water depth at the rear of the vehicle. In this case, the embodiments of this application require the front and rear airbags to be deployed simultaneously.

[0108] For example, in this embodiment of the application, the water depth at the front of the vehicle is 50cm, the water depth in the middle of the vehicle is 20cm, and the water depth at the rear of the vehicle is 5cm. In such scenarios, the front airbag can be activated first, followed by the rear airbag (multi-airbag mode).

[0109] In some embodiments, Figure 5 This is a schematic diagram of the air cushion opening according to the first specific embodiment of this application, as shown below. Figure 5 As shown, Figure 5 A simplified diagram of the car's underbody wrapping after the individual air cushion (number 3) is opened; Figure 6 This is a schematic diagram of the air cushion opening according to the second specific embodiment of this application, as shown below. Figure 6 As shown, Figure 6 A simplified diagram of the car's side lining after a single air cushion (number 6) is opened; Figure 7 This is a schematic diagram of the air cushion opening according to the third specific embodiment of this application, as shown below. Figure 7 As shown, Figure 7 A simplified diagram showing the car's undercarriage after multiple air cushions (number 4) have been deployed; Figure 8 This is a schematic diagram of the air cushion opening according to the fourth specific embodiment of this application, as shown below. Figure 8 As shown, Figure 8 A simplified diagram of the car's side lining after multiple air cushions (number 5) are deployed; Figure 9 This is a schematic diagram of the air cushion opening according to the fifth specific embodiment of this application, as shown below. Figure 9 As shown, Figure 9 A simplified diagram of the rear of the car after the air cushion (labeled 7) has been deployed.

[0110] It should be noted that the time interval between the opening of the front and rear airbags in this embodiment can be determined by a linear relationship. That is, the vehicle body angle is calculated from the sensor data, and the opening time interval is determined by a linear relationship based on the vehicle body angle.

[0111] Therefore, the vehicle protection method based on a waterproof system in this application is safer and more intelligent. Its automatic opening mode is based on an automatic opening algorithm that comprehensively considers factors such as water pressure, vehicle speed, and vehicle body angle to open the air cushion, making it safer. In multiple air cushion scenarios, the algorithm can also adjust the vehicle body posture.

[0112] Optionally, in some embodiments, waterproofing control of the vehicle according to the waterproofing strategy further includes: if the opening mode is manual mode, it is not necessary to obtain the current vehicle speed and the current pressure at at least one vehicle body position, and waterproofing control of the vehicle is performed based on a preset emergency protection strategy.

[0113] It is understood that the safety and waterproof system of this application embodiment is equipped with an emergency start button located inside the vehicle's cabin. Pressing the start button will directly activate the airbag, ignoring the current mode, for use in emergencies.

[0114] In other words, apart from the off mode, manually turning on the signal has the highest priority, and it will turn on immediately, ignoring parameters such as vehicle speed and water pressure sensors.

[0115] It should be noted that users can control the airbag via a mobile app and send control commands to the vehicle's infotainment system over the network. These control commands include setting the airbag deployment mode (off mode, manual mode, and automatic mode); forcibly deploying the airbag for remote operation, suitable for situations involving leaving the vehicle or in dangerous situations; and releasing the airbag device command to open the airbag container's gripper, allowing the airbag to detach for easy maintenance.

[0116] Therefore, in this embodiment, a water pressure sensor transmits water pressure parameters to the vehicle's decision control unit. The vehicle's decision control unit then determines whether to deploy the airbag to protect the vehicle and its occupants based on the current airbag deployment mode and an algorithm. In automatic deployment mode, factors such as water pressure, vehicle speed, and vehicle angle are comprehensively considered when deploying the airbag, resulting in greater safety. In multiple airbag scenarios, the algorithm can also adjust the vehicle's posture.

[0117] The vehicle protection method based on a waterproof system proposed in this application obtains the vehicle's current speed and the current pressure at at least one vehicle body location. Based on the current pressure at each vehicle body location, the current water depth at each location is calculated. If the current water depth at any vehicle body location is greater than a preset depth, and the duration of this excess water depth is greater than a preset duration, while the current vehicle speed is less than a preset speed, then a waterproofing strategy is determined based on the current water depth at each vehicle body location, and waterproofing control is applied to the vehicle according to this strategy. This solves the problems in related technologies, such as improper installation of air cushion components and sensors, which cannot guarantee vehicle safety in submerged environments. The method offers structural safety, convenient maintenance, and flexible opening methods, enabling the vehicle to flexibly cope with scenarios such as heavy rain, high tides, and submersion.

[0118] Next, with reference to the accompanying drawings, we describe the automotive protection device based on a waterproof system according to an embodiment of this application.

[0119] Figure 10 This is a block diagram of a car protection device based on a waterproof system according to an embodiment of this application.

[0120] like Figure 10 As shown, the vehicle protection device 10 based on a waterproof safety system includes: an acquisition module 100, a judgment module 200, and a control module 300.

[0121] Specifically, the acquisition module 100 is used to acquire the vehicle's current speed and the current pressure at at least one vehicle body position; the judgment module 200 is used to calculate the current water depth at each vehicle body position based on the current pressure at at least one vehicle body position, and to determine whether there is a current water depth at any vehicle body position that is greater than a preset depth, and the duration for which the current water depth at any vehicle body position is greater than the preset depth is greater than a preset duration, and the current vehicle speed is less than a preset speed; the control module 300 is used to determine the vehicle's waterproofing strategy based on the current water depth at each vehicle body position, and to perform waterproofing control on the vehicle based on the waterproofing strategy, in the case where there is a current water depth at any vehicle body position that is greater than the preset depth, and the duration for which the current water depth at any vehicle body position is greater than the preset depth is greater than the preset duration, and the current vehicle speed is less than the preset speed.

[0122] Optionally, in some embodiments, the control module 300 is specifically used for: acquiring the vehicle's body angle; determining whether the head water depth is greater than the middle water depth, and whether the middle water depth is greater than the tail water depth; if the head water depth is greater than the middle water depth, and the middle water depth is greater than the tail water depth, the vehicle's waterproofing strategy is to prioritize opening the front airbag, and based on the body angle, open the rear airbag after a second preset time; determining whether the head water depth is less than the middle water depth, and whether the middle water depth is less than the tail water depth; if the head water depth is less than the middle water depth, and the middle water depth is less than the tail water depth, the vehicle's waterproofing strategy is to prioritize opening the rear airbag, and based on the body angle, open the front airbag after a third preset time; determining whether the head water depth is equal to the middle water depth, and whether the middle water depth is equal to the tail water depth; if the head water depth is equal to the middle water depth, and the middle water depth is equal to the tail water depth, the vehicle's waterproofing strategy is to simultaneously open the front airbag and the rear airbag based on the body angle.

[0123] Optionally, in some embodiments, before acquiring the vehicle's current speed and the current pressure at at least one body position, the acquisition module 100 is further configured to: acquire the vehicle's maximum water depth pressure; determine whether the vehicle meets preset protection conditions based on the maximum water depth pressure; and if the vehicle does not meet the preset protection conditions, there is no need to perform waterproofing control on the vehicle.

[0124] Optionally, in some embodiments, before acquiring the vehicle's current speed and the current pressure at at least one body position, the acquisition module 100 is further configured to: determine the vehicle's opening mode; wherein the opening mode includes a closing mode, a manual mode, and an automatic mode.

[0125] Optionally, in some embodiments, the control module 300 is further configured to: when the opening mode is manual mode, without needing to obtain the current vehicle speed and the current pressure at at least one vehicle body position, and to perform waterproof control on the vehicle based on a preset emergency protection strategy.

[0126] It should be noted that the foregoing explanation of the vehicle protection method embodiment based on the waterproof system also applies to the vehicle protection device based on the waterproof system in this embodiment, and will not be repeated here.

[0127] The vehicle protection device based on a waterproof system proposed in this application obtains the vehicle's current speed and the current pressure at at least one vehicle body location. Based on the current pressure at each location, the current water depth is calculated. If the current water depth at any location is greater than a preset depth, and the duration of this excess water depth exceeds a preset duration, while the current vehicle speed is less than a preset speed, a waterproofing strategy is determined based on the current water depth at each location. The device then controls the vehicle's waterproofing according to this strategy. This solves the problems in related technologies, such as improper installation of air cushion components and sensors, which cannot guarantee vehicle safety in submerged environments. The device is structurally safe, easy to maintain, and offers flexible opening methods, allowing the vehicle to adapt flexibly to scenarios such as heavy rain, high tides, and submersion.
