Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] In modern life, vehicles have become an important means of transportation. However, while vehicles bring convenience, they also pose many safety hazards. For example, in common vehicle-to-water accidents, the lives of drivers and passengers are seriously threatened.

[0028] Because wading and submersion are quite similar, current vehicles struggle to accurately distinguish between the two conditions. Wading is a common occurrence during vehicle use and generally doesn't require emergency intervention. Currently, there are no effective methods to enhance the safety of occupants when a vehicle submerges in water.

[0029] In view of this, this application proposes a vehicle assistance rescue system and vehicle to improve the accuracy of determining whether a vehicle is in a water-crossing state or has fallen into water, and to enhance the personal safety of drivers and passengers when the vehicle is in a water-falling state.

[0030] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0031] Please refer to Figures 1 and 2. This application embodiment provides a vehicle auxiliary rescue system (or vehicle submersion auxiliary rescue system) 100, applied to a vehicle 1000 including a vehicle body 200. The vehicle 1000 can be a gasoline-powered vehicle, an electric vehicle, a hybrid vehicle, etc. For ease of understanding, this application embodiment uses an electric vehicle as an example for illustration; however, this is not a limitation of this application embodiment.

[0032] In this embodiment of the application, the vehicle assistance rescue system 100 includes a detection unit 10, a controller 20, and an inflation component 30.

[0033] The detection unit 10 is installed on the vehicle body 200. The detection unit 10 is used to sense the current road conditions of the vehicle body 200 and to sense the water level around the vehicle body 200.

[0034] The inflatable component 30 is located on the vehicle body 200 and is connected to the passenger compartment (not shown) of the vehicle body 200.

[0035] The controller 20 is disposed on the vehicle body 200 and electrically connected to the detection unit 10 and the inflator 30 respectively. The controller 20 is used to determine whether the vehicle body 200 is in a wading state or a submerged state based on the sensing information of the detection unit 10. The controller 20 is also used to control the inflator 30 to inflate the vehicle body 200 when the vehicle body 200 is in a submerged state, so as to slow down the sinking speed of the vehicle 1000. In this embodiment of the application, the wading state refers to the state in which at least one wheel of the vehicle is in contact with the water surface, the immersion depth does not exceed the wading depth threshold of the vehicle's preset position (e.g., the position of the power system or electrical components), and the vehicle can drive normally; the submerged state refers to the state in which at least a part of the vehicle is submerged in water, the immersion depth exceeds the wading depth threshold, and the vehicle cannot drive normally.

[0036] After receiving the sensing information from the detection unit 10, the controller 20 determines whether the vehicle 1000 is in a wading or submerged state. For example, if the detection unit 10 senses that the vehicle 200 is in a river or lake, with a large area of ​​water around the vehicle 200, and the water level around the vehicle 200 exceeds a safe level, then the controller 20 determines that the vehicle 1000 is submerged. If the detection unit 10 only senses that the water level around the vehicle 200 exceeds a safe level, but does not sense that the vehicle 200 is in a river or lake, and there is no large area of ​​water around the vehicle 200, then the controller 20 determines that the vehicle 1000 is wading. This improves the accuracy of the controller 20's determination of whether the vehicle 1000 is wading or submerged.

[0037] When the controller 20 determines that the vehicle 1000 is in a state of being submerged in water, the controller 20 controls the inflation component 30 to inflate the passenger compartment of the vehicle body 200, so that the air pressure in the passenger compartment is greater than the air pressure outside the vehicle. This can effectively slow down the speed at which water enters the vehicle body 200, thereby delaying the sinking speed of the vehicle 1000, buying valuable time for rescue work, and thus enhancing the personal safety of the driver and passengers.

[0038] In this embodiment, the controller 20 can be the vehicle-mounted computer of the vehicle 1000, or a separate control unit such as a PLC (Programmable Logic Controller). This embodiment does not specifically limit the controller 20.

[0039] In this embodiment, the detection unit 10 includes a road condition detection module 11 and a distance sensor (or water depth sensor) 12. The road condition detection module 11 is mounted on the vehicle body 200 and includes a radar (not shown) and / or a camera (not shown) electrically connected to the controller 20. The road condition detection module 11 is used to sense the current road condition information of the vehicle body 200. The distance sensor 12 is mounted on the vehicle body 200 and electrically connected to the controller 20. The distance sensor 12 is used to sense the water level information around the vehicle body 200. For example, the distance sensor 12 can be a pressure sensor; however, this embodiment is not limited to this.

[0040] In this embodiment, the road condition detection module 11 can sense the location of the vehicle 1000 and road condition information such as the environment around the vehicle 1000, for example, whether the vehicle 1000 is located in a river or lake, and whether there is a large area of ​​water around the vehicle 1000. The distance sensor 12 can sense the depth of the vehicle 1000 immersed in water. By setting the detection unit 10 to include the road condition detection module 11 and the distance sensor 12, it is beneficial to improve the accuracy of the detection unit 10 in sensing the current road condition information of the vehicle 200 and the water level information around the vehicle 200. In addition, by setting the road condition detection module 11 to include radar and / or camera, the radar can accurately sense the location of the vehicle 1000 and the environment around the vehicle 1000, and the camera can accurately sense the environment around the vehicle 1000 through image recognition technology, thereby improving the accuracy of the road condition detection module 11 in sensing the current road condition information of the vehicle 200.

[0041] In this embodiment, the road condition detection module 11 can be set on the top of the vehicle body 200, so that the road condition detection module 11 is set at a high position and less obstructed, which helps to improve the accuracy of the road condition detection module 11 in sensing the current road condition information of the vehicle body 200.

[0042] In this embodiment, the distance sensor 12 is located on the side wall of the vehicle body 200 and below the door (not shown). When the water level exceeds the position of the distance sensor 12, it indicates that the water is deep and water is likely to enter the passenger compartment of the vehicle body 200, making it more likely that the vehicle 1000 is in a submerged state. When the water level does not exceed the position of the distance sensor 12, it indicates that the water is shallow and it is more likely that the vehicle 1000 is in a wading state.

[0043] In other embodiments, there can be multiple distance sensors 12, which can be respectively set at different positions such as the side wall of the vehicle body 200 and the top of the vehicle body 200, thereby further facilitating the accurate sensing of water level information around the vehicle body 200. This application embodiment does not specifically limit this.

[0044] In this embodiment, the inflation component 30 can be an air tank or an inflation machine, thereby facilitating rapid inflation of the passenger compartment of the vehicle body 200.

[0045] Please refer again to Figures 1 and 2. In this embodiment, the detection unit 10 further includes an inertial sensor 13. The inertial sensor 13 is disposed on the vehicle body 200 and electrically connected to the controller 20. The inertial sensor 13 is used to sense the balance information of the vehicle body 200. The controller 20 also determines whether the vehicle body 200 is in a wading state or a submerged state based on the sensing information of the inertial sensor 13.

[0046] Specifically, the inertial sensor 13 is a functional sensor that integrates a gyroscope (not shown). The inertial sensor 13 is used to measure and track the acceleration and angular velocity of an object, thereby providing accurate attitude estimation and motion tracking.

[0047] By electrically connecting the inertial sensor 13 to the controller 20, when the controller 20 determines whether the vehicle 1000 is in a wading or submerged state, it can fit the swaying state of the vehicle 1000 based on the sensing information from the inertial sensor 13, thereby further calculating the vehicle 1000's condition in the water. When the vehicle 1000 is wading, it is generally in contact with the ground and can maintain a basic balance. When the vehicle 1000 is submerged, it will generally float in the water, and its swaying will be more severe. Thus, the inertial sensor 13 helps improve the accuracy of the controller 20 in determining whether the vehicle 1000 is in a wading or submerged state.

[0048] Referring again to Figures 1 and 2, in this embodiment, the detection unit 10 further includes a height sensor 14, which is mounted on the vehicle body 200 and electrically connected to the controller 20. The height sensor 14 is used to sense the height of the vehicle body 200 above the ground. The controller 20 also determines whether the vehicle 1000 is in a wading or submerged state based on the difference between the height of the vehicle body 200 above the ground sensed by the height sensor 14 and a preset height. In this embodiment, for example, the preset height is the installation height of the vehicle body 200, or for example, a constant value.

[0049] Specifically, when vehicle 1000 is wading through water, because the vehicle body 200 does not contact the water or the contact area is small, the buoyancy of the vehicle body 200 is less affected, and the difference between the height of the vehicle body 200 from the ground and the preset height is small. When vehicle 1000 is submerged in water, because the contact area of ​​the vehicle body 200 with the water is larger, the buoyancy of the vehicle body 200 is more affected, and the difference between the height of the vehicle body 200 from the ground and the preset height is larger. Thus, the setting of height sensor 14 helps to improve the accuracy of controller 20 in determining whether vehicle 1000 is wading through water or submerged in water. In this embodiment, the height of vehicle body 200 from the ground can be obtained based on the distance between vehicle body 200 and wheels 300, or it can be directly represented by the distance between vehicle body 200 and wheels 300. Therefore, in this case, height sensor 14 is actually used to sense the distance between vehicle body 200 and wheels 300. When vehicle 1000 falls into the water, vehicle body 200 remains suspended due to buoyancy, while wheels 300 sag due to gravity. Height sensor 14 detects the positional change of vehicle body 200 relative to wheels 300. Based on the sensing data from height sensor 14 and the aforementioned preset height, controller 20 can determine that wheels 300 have experienced unexpected and prolonged stretching, thereby determining that vehicle 1000 is in a state of submersion.

[0050] In this embodiment, the height sensor 14 can be installed on the suspension (not shown) or frame (not shown) of the vehicle body 200 near the wheel 300, so that the height sensor 14 can accurately sense the height of the vehicle body 200 from the ground.

[0051] Please refer again to Figures 1 and 2. In this embodiment, the vehicle body 200 has a ventilation port 210, which communicates with the passenger compartment. The vehicle auxiliary rescue system 100 also includes a solenoid valve 40, which is located on the vehicle body 200 at the ventilation port 210. The solenoid valve 40 is electrically connected to the controller 20. The controller 20 is also used to control the solenoid valve 40 to close the ventilation port 210 when the vehicle body 200 is submerged in water.

[0052] By providing ventilation vents 210, ventilation can be facilitated when the vehicle 1000 is in normal operation. By providing solenoid valves 40 and controllers 20 to close ventilation vents 210 when the vehicle 200 is submerged, the passenger compartment of the vehicle 200 can be made into a relatively sealed space. When the vehicle 1000 sinks, the controllers 20 control the inflation components 30 to inflate the passenger compartment. The relatively sealed space can quickly increase the air pressure inside the vehicle, thereby effectively slowing down the sinking speed of the vehicle 1000 and enhancing the personal safety of the occupants.

[0053] Please refer again to Figures 1 and 2. In this embodiment, the vehicle body 200 is provided with multiple adjustment holes 220, which are connected to the inflator 30. The controller 20 is also used to control the inflator 30 to release air through the multiple adjustment holes 220 when the vehicle body 200 is in a submerged state, so as to adjust the balance of the vehicle 1000.

[0054] Specifically, when vehicle 1000 floats in water, it may tilt or even overturn due to uneven force distribution on its various parts, thus reducing the chances of escape for the occupants. By setting multiple adjustment holes 220 and a controller 20 to control the airflow from the inflation component 30 through these holes, the vehicle 1000 can maintain its balance when floating in water. This facilitates the escape of the occupants and enhances their safety.

[0055] Please refer again to Figures 1 and 2. In this embodiment, the vehicle assistance rescue system 100 further includes an alarm module 50, which is located on the vehicle body 200 and electrically connected to the controller 20. The controller 20 is also used to control the alarm module 50 to sound an alarm when the vehicle body 200 is submerged in water. This facilitates rescue personnel in quickly determining the location of the vehicle 1000 and also helps remind the driver and passengers to take timely self-rescue measures, thereby enhancing the personal safety of the driver and passengers.

[0056] In this embodiment, the alarm module 50 can be an audible and visual alarm, and it can be mounted on the top of the vehicle body 200. In other embodiments, the alarm module 50 can also be integrated with the controller 20, and includes a software module (not shown) capable of making telephone dialing alarms. For example, when the controller 20 determines that the vehicle 1000 is in a submerged state, the controller 20 controls the alarm module 50 to automatically dial emergency numbers such as 110 and 119 to make an alarm. This embodiment does not specifically limit this aspect.

[0057] Referring again to Figures 1 and 2, in some other embodiments, the vehicle assistance rescue system 100 also includes an anti-sinking airbag 60, which is disposed on the vehicle body 200 and connected to the inflator 30. The controller 20 is also used to control the inflator 30 to inflate the anti-sinking airbag 60 when the vehicle body 200 is in a submerged state. After inflation, the anti-sinking airbag 60 provides buoyancy to reduce the probability of the vehicle 1000 sinking, thereby enhancing the personal safety of the occupants.

[0058] In other embodiments, there may be multiple anti-sinking airbags 60, which are respectively disposed on the periphery and top of the vehicle body 200. Before inflation, the anti-sinking airbags 60 are in a compressed state for easy storage. When inflated, the anti-sinking airbags 60 deploy from the vehicle body 200 and provide buoyancy from multiple locations, thereby further reducing the probability of the vehicle 1000 sinking and the probability of the vehicle 1000 tilting.

[0059] The working process of the vehicle assistance rescue system 100 in this application embodiment is roughly as follows.

[0060] The controller 20 determines whether the vehicle 1000 is in a wading or submerged state based on the sensing information from the road condition detection module 11, distance sensor 12, inertial sensor 13 and height sensor 14.

[0061] When vehicle 1000 is submerged in water, controller 20 controls solenoid valve 40 to close ventilation port 210, making the passenger compartment of vehicle body 200 a relatively sealed space. At the same time, controller 20 controls alarm module 50 to sound an alarm.

[0062] When the vehicle 1000 has floated and sunk to a certain depth, the controller 20 controls the inflator 30 to inflate the passenger compartment to slow down the sinking speed of the vehicle 1000. The controller 20 also controls the inflator 30 to vent through multiple adjustment holes 220 to adjust the balance of the vehicle 1000.

[0063] In some other embodiments, when the vehicle 1000 sinks to a certain depth, the controller 20 also controls the inflator 30 to inflate the anti-sinking airbag 60, which provides buoyancy after inflation to reduce the probability of the vehicle 1000 sinking.

[0064] In summary, the vehicle auxiliary rescue system 100 of this application improves the accuracy of determining whether the vehicle 200 is in a wading or submerged state by setting the controller 20 to determine whether the vehicle 200 is in a wading or submerged state based on the sensing information of the detection unit 10. By setting the controller 20 to control the inflation component 30 to inflate the passenger compartment when the vehicle 200 is submerged, the air pressure in the passenger compartment is greater than the air pressure outside the vehicle, effectively slowing down the sinking speed of the vehicle 1000, buying valuable time for rescue work, and thus enhancing the personal safety of the driver and passengers.

[0065] Please refer to Figure 2. This application embodiment also provides a vehicle 1000, including a vehicle body 200, wheels 300, and a vehicle auxiliary rescue system 100 as described above.

[0066] In this embodiment, the vehicle body 200 is provided with a ventilation hole 210 and multiple adjustment holes 220. The road condition detection module 11, distance sensor 12, inflation component 30, controller 20, inertial sensor 13, height sensor 14, solenoid valve 40, alarm module 50 and anti-sinking airbag 60 of the vehicle auxiliary rescue system 100 are all provided on the vehicle body 200.

[0067] The vehicle 1000 in this embodiment improves the accuracy of determining whether the vehicle 1000 is in a water-crossing state or has fallen into water by setting up a vehicle assistance rescue system 100, and enhances the personal safety of the driver and passengers when the vehicle 1000 is in a water-falling state.

[0068] Please refer again to Figures 1 and 2. In this embodiment, the vehicle 1000 further includes a suspension system 400 connected to the vehicle body 200. The suspension system 400 is connected to the vehicle body 200 and the wheels 300 respectively, and can raise and lower the vehicle body 200. The controller 20 is also electrically connected to the suspension system 400. The controller 20 is also used to control the suspension system 400 to raise the vehicle body 200 within a safe lifting range when the vehicle 1000 is in a water-crossing state, and to control the suspension system 400 to raise the vehicle body 200 beyond the safe lifting range to the maximum height when the vehicle 1000 is in a submerged state. In this embodiment, the safe lifting range refers to the lifting range within which the suspension system can raise the vehicle body without causing damage to the suspension system, while the maximum height refers to the limit value that the suspension system can reach when raising the vehicle body without considering whether the suspension system will be damaged, and this limit value is greater than the maximum value of the aforementioned safe lifting range. However, this embodiment is not limited to this. For example, in another embodiment of this application, when the vehicle 1000 is in a submerged state, the suspension system 400 can be controlled using the following strategy: when the suspension system 400 raises the vehicle body 200 to a safe lifting range and the wading depth of the vehicle 1000 is sufficient to allow the occupants to escape safely, the vehicle body 200 will no longer be raised; when the suspension system 400 raises the vehicle body 200 to the limit of the safe lifting range and the wading depth of the vehicle 1000 is insufficient to allow the occupants to escape safely and poses a threat to their lives, the suspension system 400 will directly raise the vehicle body 200 to the maximum height to ensure the safety of the occupants.

[0069] Specifically, the suspension system 400 can be an air suspension. Suspension systems generally have a safe lifting range; exceeding this range may damage the suspension system 400. When the vehicle 1000 is in a wading state, the controller 20 controls the suspension system 400 to raise the vehicle body 200 within the safe lifting range, facilitating the vehicle 1000's smooth passage through shallow, small areas of water without damaging the suspension system 400. When the vehicle 1000 is submerged, the controller 20 controls the suspension system 400 to raise the vehicle body 200 to its maximum height beyond the safe lifting range. This increases the distance between the top of the vehicle body 200 and the water surface before the vehicle 1000 is completely submerged, or shortens the distance when the vehicle 1000 is completely submerged, thus enhancing the safety of the occupants.
