Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a pressure-sensing-based emergency response system for vehicles falling into water and automotive products. Background Technology

[0002] When a car is driving near a river, stream, pond, or reservoir, there is a risk of it falling into the water due to road collapses or driver error. Passengers in the car will be submerged as water enters the vehicle, and escape will be difficult due to the obstruction of the car's interior. Since most ordinary drivers lack professional training, panic during a car accident can make them unable to save themselves, hindering their ability to use safety hammers or other life-saving devices, or even their mobile phones to call for help.

[0003] Currently, some automotive technologies attempt to detect whether a car has fallen into water by installing liquid level sensors on the vehicle body, thereby automatically triggering distress signals and other emergency procedures upon detection. While these technologies can help panicked drivers call for help in the event of a car falling into water, their practical value is limited by their operating principles. Specifically, the sensitivity and reliability of these technologies are closely related to the installation location of the liquid level sensor. If the sensor is installed too low, such as near the wheels, it may be misidentified as a car falling into water even when simply driving through a puddle. Conversely, if the sensor is installed too high, such as on the roof, it may only detect water damage when the car is completely submerged. However, by this time, the car's electronic components and circuits may have already been damaged by water and short-circuited, rendering these technologies ineffective in their emergency response function. Summary of the Invention

[0004] In view of at least one of the above-mentioned technical problems, the purpose of the present invention is to provide a pressure-sensing-based emergency treatment system for vehicles falling into water and a vehicle product.

[0006] Furthermore, the plurality of mounting locations include the front chassis, the rear chassis, the left sill beam, and the right sill beam.

[0007] Furthermore, determining the vehicle's submersion status based on the pressure data includes: Set the pressure magnitude threshold and pressure change rate threshold for each of the aforementioned pressure sensors; For any of the pressure sensors, if the magnitude of the pressure data detected by the pressure sensor is greater than the pressure threshold and the rate of change of the pressure data is greater than the pressure rate of change threshold, the pressure sensor is identified as a high-pressure sensor; otherwise, the pressure sensor is identified as a low-pressure sensor.

[0009] Furthermore, determining the vehicle's submersion status based on the pressure data includes: Set a second pressure threshold value corresponding to the suspension sensor; When the detected value of the second pressure data is less than the second pressure value threshold, timing begins to obtain a dynamically increasing timing value; Dynamically set a first pressure magnitude threshold that remains positively correlated with the timing value; When the magnitude of the first pressure data is detected to be greater than the first pressure magnitude threshold, the state of falling into the water is determined to be that the person has fallen into the water; otherwise, the state of falling into the water is determined to be that the person has not fallen into the water.

[0012] Furthermore, the execution module includes an emergency inflation device and an airbag, wherein the emergency inflation device is used to inflate the airbag when the water-falling state is that the water has fallen into the water.

[0013] Furthermore, the emergency inflation device is used to draw in air for storage when the water-falling state is not water-falling.

[0014] On the other hand, embodiments of the present invention also include an automotive product, the automotive product including the pressure-sensing-based emergency handling system for vehicles falling into water as described in the embodiments.

[0015] The beneficial effects of the present invention are as follows: The pressure-sensing-based emergency handling system for cars falling into water in the embodiments only causes a large number of pressure sensors to become high-pressure sensors when the car falls into a river, pond, or other body of water. Therefore, by detecting the number of high-pressure sensors, the car's water-falling status can be effectively determined. It is less affected by the interference caused by the car wading through shallow puddles or rain, thereby reducing the occurrence of misjudgments when the car is driving normally and has not fallen into water. Thus, it accurately and sensitively detects the car's water-falling status, ensuring the safety of life and property of the people in the car. Attached Figure Description

Detailed Implementation

[0017] This embodiment provides a pressure-sensing-based emergency response system for vehicles falling into water. (Refer to...) Figure 1The pressure-sensing-based emergency response system for vehicles submerged in water includes a sensing module, a control module, and an execution module. The sensing module comprises multiple pressure sensors, which are distributed across various mounting locations on the vehicle body. Each pressure sensor detects pressure at its mounting location, obtains pressure data, and sends the detected pressure data to the control module.

[0018] For example, refer to Figure 2 Multiple mounting locations can be set on components such as the front chassis, rear chassis, left sill beam, and right sill beam of the car, and a pressure sensor can be installed at each mounting location.

[0019] In this embodiment, all pressure sensors follow a uniform sampling time sequence. t 1, t 2, t 3…… t n The pressure at its installation location is measured sequentially at each sampling time.

[0020] Among them, the first i Taking a pressure sensor as an example, at the sampling time t 1. Pressure data was obtained from the detection. p i_1 At the sampling time t 2. Pressure data obtained from the detection p i_2 At the sampling time t 3. Pressure data obtained from the test p i_3 ...at the sampling time t n Pressure data was obtained. p i_n and the detected pressure data p i_1 , p i_2 , p i_3 ... p i_n It is sent to the control module in real time.

[0021] In this embodiment, pressure data p i_1 , p i_2 , p i_3 ... p i_n Specifically, it can be the first iEach pressure sensor detects pressure (in Newtons) or pressure intensity (in Pascals). The control module can calculate the rate of change of pressure over time based on the pressure data detected by the same pressure sensor. Specifically, the sampling time sequence... t 1, t 2, t 3…… t n It has equal time intervals, meaning the duration between any two adjacent sampling times is Δ. t So, the first i Each pressure sensor at the sampling time t 2. Rate of change of the detected pressure data R i_2 =( p i_2 - p i_1 ) / Δ t At sampling time t 3. The rate of change of the detected pressure data R i_3 =( p i_3 - p i_2 ) / Δ t ... At sampling time t n The rate of change of the detected pressure data R i_n =( p i_n - p i_n-1 ) / Δ t Thus, the first i Rate of change of pressure data detected by each pressure sensor at various sampling times R i_2 , R i_3 ... R i_n .

[0022] In this embodiment, when using Figure 2 The pressure sensors are installed as shown. When the control module acquires pressure data from the sensor module and determines the vehicle's submersion status based on this data, it refers to... Figure 3 Specifically, the following steps can be performed: S1. Set the pressure magnitude threshold and pressure change rate threshold for each pressure sensor; S2. For any pressure sensor, if the pressure data detected by the pressure sensor is greater than the pressure threshold and the rate of change of the pressure data is greater than the pressure change rate threshold, the pressure sensor is identified as a high-pressure sensor; otherwise, the pressure sensor is identified as a low-pressure sensor. S3. Set the quantity threshold; S4. When the total number of all high-voltage sensors is greater than or equal to the number threshold, the state of falling into the water is determined to be "fallen into the water"; otherwise, the state of falling into the water is determined to be "not fallen into the water".

[0023] In step S1, the corresponding pressure threshold can be set based on the height of each pressure sensor's installation position on the car body from the ground. Specifically, the car body can be submerged in water to a specific height (e.g., the height corresponding to the engine hood). H ( ) as the criterion for judging whether a car has fallen into water, with the first one being the most important. i Taking a pressure sensor as an example, its installation position (below the engine compartment hood) is at a height of [missing information]. h i So when the car body is submerged to a certain height... H At that time, the first i The pressure sensor is located at a depth of [depth missing] below the water surface. H - h i At the location, the detected pressure is ρg( H - h i ), where ρ is the density of water and g is the acceleration due to gravity, therefore the first... i Pressure threshold corresponding to each pressure sensor p_threshold i Set as p_threshold i =ρg( H - h i ) (1) In step S1, the car body can be moved in a short time. t '(For example t Within 3 seconds, the water will be submerged to a specific height. H As a criterion for judging whether a car has fallen into water, the first one is used. i Taking a pressure sensor as an example, the pressure it detects is in the range of t The time interval increases from 0 to p_threshold i Therefore, the first i Pressure change rate threshold corresponding to each pressure sensor R_thresholdi Set as R_threshold i = p_threshold i / t ' (2) In step S2, the control module iterates through all the pressure sensors, taking the first one as an example. i Taking the first pressure sensor as an example, the control module determines the first... i The test determines whether the magnitude of the latest pressure data detected by the pressure sensor is greater than the pressure threshold determined by formula (1), and whether the rate of change of the latest detected pressure data is greater than the pressure rate of change threshold determined by formula (2). If both conditions are met, then the test will be performed on the first pressure sensor. i If a pressure sensor is determined to be a high-pressure sensor, and neither of these conditions is met simultaneously (e.g., the pressure data is less than the pressure threshold and the rate of change of the pressure data is less than the pressure rate of change threshold, or the pressure data is greater than the pressure threshold, but the rate of change of the pressure data is less than the pressure rate of change threshold), then the first pressure sensor is determined to be a high-pressure sensor. i The pressure sensor was determined to be a low-pressure sensor.

[0024] In step S3, a specific fixed value can be set as the quantity threshold. In this embodiment, half of the total number of pressure sensors can be set as the quantity threshold. Thus, when executing step S4, if half or more of the pressure sensors are high-pressure sensors, the control module determines that the car has fallen into the water; if less than half of the pressure sensors are high-pressure sensors, the control module determines that the car has not fallen into the water.

[0025] In this embodiment, the principle of the pressure-sensing-based emergency response system for vehicles falling into water and the execution steps S1-S4 is as follows: By setting up a sensing module including multiple pressure sensors, under normal conditions when the vehicle is not in water, the pressure data detected by each pressure sensor is ideally zero (the influence of atmospheric pressure has been zeroed out). Only when the vehicle falls into a river, pond, or other body of water will a large number of pressure sensors become high-pressure sensors due to the detection of large pressure data and the rate of change of pressure data. Therefore, by detecting the number of high-pressure sensors, the vehicle's water-falling status can be effectively determined. Compared with related technologies using liquid level sensors, the pressure-sensing-based emergency response system for vehicles falling into water in this embodiment is less affected by the vehicle wading through shallow puddles or rain, thereby reducing the occurrence of misjudgments when the vehicle is driving normally and has not fallen into water. This allows for accurate and sensitive detection of the vehicle's water-falling status, ensuring the safety of life and property of the people in the vehicle.

[0026] In this embodiment, in addition to being able to follow Figure 2Install each pressure sensor at the indicated mounting location, or as shown in the diagram. Figure 4 Install each pressure sensor at the indicated mounting location.

[0027] Reference Figure 4 These installation locations include the tires and suspension structure of a vehicle. Specifically, some pressure sensors can be installed inside the tires, and some pressure sensors can be installed at the locations of components such as springs in the suspension structure. In this embodiment, the pressure sensors installed inside the tires are called tire sensors, and the pressure sensors installed at the suspension structure are called suspension sensors.

[0028] In this embodiment, the tire sensor obtains pressure data by detecting the tire pressure of the tire it is in. Specifically, the tire sensor can be zeroed so that its zero point is consistent with the tire pressure of the tire (typically around 2.5 bar). Thus, the pressure data detected by the tire sensor represents the pressure increase caused by external pressure on the tire, such as water immersion. In this embodiment, the tire pressure detected by the tire sensor is referred to as the first pressure data.

[0029] In this embodiment, a spring travel sensor can be used as a suspension sensor. This type of sensor can detect the travel of the spring in the suspension structure relative to its equilibrium position. The magnitude of the spring force on the suspension structure is calculated using the spring force formula. This spring force is actually the pressure transmitted from the vehicle body to the wheels by the suspension structure where the sensor is located. In this embodiment, the tire pressure detected by the suspension sensor is referred to as the second pressure data.

[0030] In this embodiment, one or more tire sensors or one or more suspension sensors can be set. Regardless of the number of tire sensors and suspension sensors, the principle is the same. The following explanation uses one tire sensor and one suspension sensor as an example.

[0031] In this embodiment, when using Figure 4 The pressure sensors are installed as shown. When the control module acquires pressure data from the sensor module and determines the vehicle's submersion status based on this data, it refers to... Figure 5 Specifically, the following steps can be performed: P1. Set the second pressure threshold value corresponding to the suspension sensor; P2. When the detected second pressure data is less than the second pressure threshold, timing begins to obtain dynamically increasing timing values; P3. Dynamically set and maintain a first pressure magnitude threshold that is positively correlated with the timing value; P4. When the detected first pressure data is greater than the first pressure threshold, the state of falling into the water is determined to be that the person has fallen into the water; otherwise, the state of falling into the water is determined to be that the person has not fallen into the water.

[0032] In step P1, a certain proportion (e.g., 1 / 3) of the pressure transmitted from the vehicle body to the wheels under normal conditions can be set as the second pressure threshold. This is because in this embodiment, it is a suspension sensor, which is 1 / 4 of the total pressure generated by the weight of the vehicle body, i.e., the part above the chassis.

[0033] In step P2, once the control module detects that "the magnitude of the second pressure data detected by the suspension sensor is less than the second pressure magnitude threshold", it starts timing from zero using a timer to obtain the timing value. timing In this embodiment, the timing value timing It grows dynamically, meaning that once step P2 is executed and the timer is triggered, subsequent steps will not stop the timer; it will continue to keep the timer running and obtain the time value. timing For example, timing value timing It can represent the number of seconds since the event "the size of the second pressure data is detected to be less than the second pressure size threshold" occurred.

[0034] In step P3, the control module can proceed according to the formula. F_threshold = mg × timing / Δ T (3) The first pressure magnitude threshold is calculated. F_threshold .in, m For the curb weight of the car, g Let Δ be the acceleration due to gravity. T For a fixed duration of a very small amount (e.g., 0.1s).

[0035] In this embodiment, the first pressure threshold is calculated using formula (3). F_threshold The meaning is that the curb weight is m The car's initial velocity is 0, and it travels for a duration of... timing After being accelerated by gravitational acceleration, in a very short time, Δ T The rate of change of external pressure on the tires of a car when the internal deceleration is 0.

[0036] In this embodiment, due to the timing value timing It is dynamically changing, therefore the first pressure magnitude threshold is calculated using formula (3). F_threshold It is also dynamic and changing.

[0037] In this embodiment, since the tire sensor is a specific pressure sensor, the first pressure data detected by the tire sensor in step P4 can also be expressed as... p i_1 , p i_2 , p i_3 ... p i_n In the form of step P4, the control module continuously updates the latest detected first pressure data with the timing value corresponding to the detection time of the first pressure data. timing The first pressure threshold is calculated using formula (3). F_threshold A size comparison is performed; if the size of the first pressure data is detected to be greater than the corresponding first pressure size threshold, the result is considered positive. F_threshold If the detected first pressure data is less than or equal to the corresponding first pressure threshold, then the state of falling into the water is determined as having fallen into the water. F_ threshold If so, then the state of falling into the water is determined to be not falling into the water.

[0038] In this embodiment, according to Figure 4The principle behind setting up the pressure sensor and executing steps P1-P4 as shown is as follows: Compared to non-dangerous events such as a car wading through shallow water, the characteristics of a real water-falling event, such as a car falling into a river or pond, are that the car undergoes a falling process for a period of time (e.g., a car falling from a bridge into a river) and is subjected to a strong impact after the falling process (e.g., a car hitting the water surface). During the falling process, the car is in a state of weightlessness, resulting in a decrease in the pressure transmitted from the car body to the wheels through the suspension structure (ideally to zero). Therefore, by setting a small second pressure threshold in step P1, the start of the weightlessness state can be detected when the second pressure data detected by the suspension sensor is less than the second pressure threshold, thus detecting that the car has entered the falling process. The timing value obtained in step P2 represents the duration of the falling process. During this process, the car is accelerated by gravity, and its speed relative to the water surface continues to increase. By executing step P3, the first pressure threshold is set to represent the pressure level of the car components (e.g., tires) when the car immediately hits the water surface at each moment during the falling process. If If step P4 detects that the magnitude of the first pressure data is greater than the first pressure threshold, it can be determined that the car's tires were impacted by the water surface, thus experiencing pressure matching the speed generated by the duration of the fall. Therefore, a real water-falling event can be determined, and the car is classified as having fallen into the water. Conversely, if the magnitude is less than the threshold, the car is classified as not having fallen into the water. By executing steps P1-P4, in the case of a real water-falling event such as a car falling into a river or pond, the water-falling state can be accurately determined as having fallen into the water. However, in the case of a non-dangerous wading event such as a car wading through a shallow puddle, the conditions in steps P1-P4 are not met because there is no fall (resulting in no weightlessness and the second pressure data being less than the second pressure threshold) and the impact speed on the water surface is not sufficiently high (resulting in less pressure on the car's tires). Therefore, the car is classified as not having fallen into the water. Thus, by executing steps P1-P4, the identification of whether a car has actually fallen into the water can be accurately determined, thereby improving the sensitivity of real water-falling event identification and reducing the impact of misjudgments in non-dangerous wading events.

[0039] In this embodiment, by executing steps P1-P4, the water-falling state can be identified during the car's fall and within a short time of impact with the water surface. This means that it is not necessary for the car to be submerged to a certain height (such as the height of the engine hood) before the water-falling state can be identified. Therefore, it is beneficial to identify the water-falling state as quickly as possible, so that the control module can promptly control the execution module to perform emergency actions before various components in the car fail due to short circuits or other reasons caused by water immersion. This helps to protect the life and property safety of the car that has fallen into the water.

[0040] In this embodiment, whether the vehicle is detected as having fallen into the water through steps S1-S4 or steps P1-P4, the control module can control the execution module to perform emergency actions.

[0041] In this embodiment, different units within the execution module perform different emergency actions. Specifically, refer to... Figure 1 The sunroof emergency opening unit in the execution module includes an emergency power supply and a drive circuit. When the control module detects that the vehicle has fallen into water, it sends a control command to the sunroof emergency opening unit. This triggers the emergency power supply in the unit to provide drive power to the sunroof motor through the drive circuit, allowing the sunroof located on the roof to open promptly, providing an escape route for occupants. By incorporating this sunroof emergency opening unit, it is beneficial in situations where the car is submerged in water and the doors and other components are subjected to high water pressure, making them impossible to open manually. This allows occupants to escape smoothly, thus ensuring the safety of life and property.

[0042] Reference Figure 1 The execution module includes an emergency inflation device and an airbag. In this embodiment, the emergency inflation device includes an air pump or a gas generator (e.g., generating oxygen through a chemical reaction), and is connected to the airbag via an air tube. If the control module detects that the vehicle is not in water, it does not send a control command to the emergency inflation device. The device can, without receiving a control command, automatically draw in air and store it through internal cylinders or other components. When the control module detects that the vehicle has fallen into water, it sends a control command to the emergency inflation device, triggering it to release the air stored in the cylinder or generate oxygen through a chemical reaction, inflating the air or oxygen into the airbag through the tube. The inflated airbag, due to its large volume, experiences significant buoyancy in water, acting as a lifebuoy. Furthermore, a vent can be provided on the airbag, allowing occupants to release oxygen or other gases for inhalation when necessary, thus acting as an oxygen source.

[0043] Reference Figure 1 The execution module includes a communication unit. When the control module detects that the car has fallen into the water, it sends a control command to the communication unit, triggering the communication unit to broadcast a distress signal to a fixed receiver or to the outside world. This allows external personnel to receive the distress signal through communication devices, enabling them to understand that a car has fallen into the water and to carry out rescue efforts. This increases the likelihood of the car and its occupants being rescued, thus ensuring the safety of life and property.

[0044] A pressure-sensing-based emergency response system for cars that have fallen into water can be installed on a vehicle, thus providing the full technical benefits of such a system.
