Description

Technical Field

[0001] This application relates to the technical field, and in particular to a YTS-based intelligent terminal vehicle emergency call method, device, and electronic device. Background Technology

[0002] With the rapid development of intelligent transportation systems and vehicle-to-everything (V2X) technology, the automatic emergency call function of end vehicles in the event of an accident has become an important component of modern automotive safety systems. Existing vehicle accident emergency call systems typically rely on automatically sending vehicle emergency call information to emergency service centers via built-in communication modules (such as emergency call systems).

[0003] However, existing vehicle accident emergency call systems have certain limitations. The system can only provide limited accident information and cannot accurately determine detailed information. Therefore, the effectiveness of emergency calls for help corresponding to accidents involving terminal vehicles is low in terms of targeting and accuracy. Summary of the Invention

[0004] The purpose of this invention is to provide a method, device, and electronic device for vehicle emergency calls based on YTS (Yonta-Signal System) to solve the technical problems of low targeting and accuracy of emergency calls for vehicles involved in accidents.

[0005] In a first aspect, the present invention provides a vehicle emergency call method based on YTS smart terminal, wherein a shock absorber is installed at a corresponding position for each seat in the vehicle; the method includes: Sub-vibration data is collected by multiple shock absorbers corresponding to multiple car seats, and it is determined whether there is a passenger on the car seat based on the sub-vibration data corresponding to each car seat; If there is a passenger in the vehicle seat, the passenger weight in the vehicle seat is detected based on the sub-vibration data, and a distribution map of the positions of multiple vehicle seats and corresponding passenger weights in the vehicle is generated by YTS based on the passenger weight and the position of the vehicle seat in the vehicle; each vehicle seat is equipped with at least one airbag. The system acquires the comprehensive vibration value of the vehicle. If the comprehensive vibration value exceeds a specified vibration data point, it determines that a vehicle accident is imminent. Based on the comprehensive vibration value and the distribution map, it pre-determines the airbag deployment level for each seat. The higher the comprehensive vibration value, the greater the total airbag deployment level. In the distribution map, the greater the passenger weight, the greater the airbag deployment level for the corresponding seat. Furthermore, the closer the seat is to the front of the vehicle, the greater the corresponding airbag deployment level. Based on the distribution map, the comprehensive vibration value, the deployment degree of each airbag, and the sub-vibration data, a smart terminal vehicle emergency call signal is generated for each passenger in each of the vehicle seats, and the smart terminal vehicle emergency call signal is sent based on the vehicle accident; the greater the airbag deployment degree and / or the sub-vibration data, the stronger the emergency call intensity of the smart terminal vehicle emergency call signal for the corresponding passenger in the vehicle seat.

[0006] In an optional implementation, a first distance sensor is provided at a corresponding position of each of the vehicle seats, the sensing direction of the first distance sensor being the vehicle seat; after determining that a vehicle accident is imminent in response to the overall vibration value being greater than a specified vibration data, the method further includes: In response to the vehicle accident, the vehicle issues an emergency protection warning sound, which includes the content of the passenger's designated emergency protection posture; the first distance sensor detects whether the passenger's posture on the seat conforms to the designated emergency protection posture, and obtains the protection posture detection result; The step of determining the airbag deployment level for each vehicle seat in advance based on the comprehensive vibration values ​​and the distribution map includes: The airbag deployment level for each vehicle seat is determined in advance based on the comprehensive vibration value, the distribution state diagram, and the protective posture detection results; if the passenger posture in the protective posture detection results matches the specified emergency protective posture, the airbag deployment level is adjusted to decrease.

[0007] In an optional implementation, the step of determining the airbag deployment level for each of the vehicle seats in advance based on the comprehensive vibration values ​​and the distribution map includes: Based on the comprehensive vibration values ​​and the distribution map, the airbag deployment level for each vehicle seat is determined in advance using the following formula:

[0008] in, This represents the combined vibration value; This represents the passenger weight corresponding to the i-th seat in the distribution diagram; This represents the passenger weight corresponding to the j-th seat in the distribution diagram; The position attenuation coefficient of the vehicle seat is represented; e is a mathematical constant representing the base of the natural logarithm. This represents the standardized position coefficient corresponding to the i-th seat in the distribution diagram; The weight of the passenger corresponding to the k-th seat in the distribution diagram is represented by n; n represents the total number of seats in the vehicle. This represents the standardized position coefficient corresponding to the k-th seat in the distribution diagram; This represents the vibration weighting coefficient; Indicates the weighting coefficient; Indicates the vibration gain coefficient; This indicates the degree of airbag deployment.

[0009] In an optional implementation, the vehicle is equipped with multiple second distance sensors, with different second distance sensors facing different directions outside the vehicle; after determining that the vehicle is about to be involved in a vehicle accident, the method further includes: The vehicle detects multiple actual distances between itself and external collisionable objects using multiple second distance sensors, as well as the rate of decrease in distance between itself and external collisionable objects. Based on the multiple actual distances and multiple distance reduction rates corresponding to the second distance sensors, the target second distance sensor corresponding to the first external collideable object is determined from the multiple second distance sensors; The target position of the vehicle itself, where a vehicle collision is about to occur, is determined based on the location of the second distance sensor on the vehicle. Based on the position of the vehicle seats in the distribution diagram, a target airbag with an interval less than a specified interval between it and the target position of the vehicle itself is determined from the multiple airbags corresponding to the multiple vehicle seats, and the target airbag is controlled to be released in advance.

[0010] In an optional implementation, the step of determining the airbag deployment level for each vehicle seat in advance based on the comprehensive vibration value and the distribution map includes: The airbag deployment level for each seat is determined in advance based on the distance between the seat and the target position of the vehicle, the comprehensive vibration value, and the distribution map; the smaller the distance between the seat and the target position of the vehicle, the greater the airbag deployment level.

[0011] In an optional implementation, a seatbelt is provided at a corresponding position for each of the vehicle seats; after generating a distribution map of the positions and corresponding passenger weights of multiple vehicle seats in the vehicle using YTS based on the passenger weight and the positions of the vehicle seats in the vehicle, the method further includes: In response to the overall vibration value being greater than a specified vibration data, the cushioning release degree of the seat belt for each of the vehicle seats is determined in advance based on the overall vibration value and the distribution state diagram; the larger the overall vibration value, the smaller the cushioning release degree; the greater the passenger weight in the distribution state diagram, the greater the corresponding cushioning release degree of the vehicle seat; and the closer the position of the vehicle seat in the distribution state diagram is to the front of the vehicle, the smaller the corresponding cushioning release degree.

[0012] In an optional implementation, the step of responding to the overall vibration value being greater than a specified vibration data point, and determining in advance the cushioning release level of the seat belt for each of the vehicle seats based on the overall vibration value and the distribution map, includes:

[0013]

[0014] in, This indicates the degree of cushioning release of the seat belt; This represents the combined vibration value; This represents the passenger weight corresponding to the i-th seat in the distribution diagram; Indicates the nonlinearity of vibration; This represents the normalized position before and after the i-th seat in the distribution diagram; Indicates the weight sensitivity index; Indicates the position attenuation coefficient; Indicates the vibration suppression coefficient; Represents the global logarithmic decay coefficient; This represents the normalized position before and after the k-th seat in the distribution diagram.

[0015] Secondly, the present invention provides a YTS-based intelligent terminal vehicle emergency call device, wherein a shock absorber is installed at a corresponding position for each seat in the vehicle; the device includes: The data acquisition module is used to acquire sub-vibration data through multiple shock absorbers corresponding to multiple car seats, and to determine whether there is a passenger on the car seat based on the sub-vibration data corresponding to each car seat. The generation module is used to detect the passenger weight of the passenger in the seat based on the sub-vibration data if there is a passenger in the seat, and generate a distribution map of the position and corresponding passenger weight of multiple seats in the vehicle through YTS based on the passenger weight and the position of the seat in the vehicle; each seat is equipped with at least one airbag. The determination module is used to acquire the comprehensive vibration value of the vehicle. In response to the comprehensive vibration value being greater than a specified vibration data, it determines that the vehicle is about to have an accident. Based on the comprehensive vibration value and the distribution state diagram, it pre-determines the airbag deployment degree for each airbag corresponding to each seat. The larger the comprehensive vibration value, the larger the sum of the deployment degrees of all airbags. The greater the passenger weight in the distribution state diagram, the greater the airbag deployment degree of the corresponding seat. The closer the seat is to the front of the vehicle in the distribution state diagram, the greater the corresponding airbag deployment degree. The sending module is used to generate a smart terminal vehicle emergency call signal for each passenger in each of the vehicle seats based on the distribution state map, the comprehensive vibration value, the deployment degree of each of the airbags, and the sub-vibration data, and to send the smart terminal vehicle emergency call signal based on the vehicle accident; the greater the airbag deployment degree and / or the sub-vibration data, the stronger the emergency call intensity of the smart terminal vehicle emergency call signal for the corresponding passenger in the vehicle seat.

[0016] Thirdly, the present invention provides an electronic device, including a memory and a processor, wherein the memory stores a computer program that can run on the processor, and the processor executes the computer program to implement the steps of the method described in any of the foregoing embodiments.

[0017] Fourthly, the present invention provides a computer-readable storage medium storing computer-executable instructions, which, when invoked and executed by a processor, cause the processor to perform the method described in any of the foregoing embodiments.

[0018] This application brings the following beneficial effects: This application provides a vehicle emergency call method, device, and electronic device based on YTS (Yet-Time Steering) for smart terminals. It can collect sub-vibration data from multiple shock absorbers corresponding to multiple vehicle seats, and determine whether a passenger is present on each seat based on the sub-vibration data. If a passenger is present, the weight of the passenger is detected based on the sub-vibration data, and a distribution map of the positions of multiple seats and their corresponding passenger weights is generated using YTS based on the passenger weight and the seat's position in the vehicle. Each seat is equipped with at least one airbag. The system acquires the vehicle's overall vibration value; if the overall vibration value exceeds a specified vibration value, it determines that a vehicle accident is imminent and anticipates the accident based on the overall vibration value and the distribution map. The airbag deployment level of each airbag corresponding to each vehicle seat is determined; the larger the comprehensive vibration value, the greater the sum of the deployment levels of all airbags; the greater the passenger weight in the distribution diagram, the greater the deployment level of the corresponding airbag for that vehicle seat; the closer the vehicle seat is to the front of the vehicle in the distribution diagram, the greater the deployment level of the corresponding airbag; based on the distribution diagram, the comprehensive vibration value, the deployment level of each airbag, and the sub-vibration data, a smart terminal vehicle emergency call signal is generated for each passenger in each vehicle seat, and the smart terminal vehicle emergency call signal is sent based on the vehicle accident; the greater the airbag deployment level and / or the sub-vibration data, the stronger the emergency call intensity of the smart terminal vehicle emergency call signal for the passenger in the corresponding vehicle seat. In this system, each seat is equipped with a shock absorber. These shock absorbers not only provide a comfortable ride but also collect sub-vibration data. Based on this data, the system can determine whether a passenger is present in each seat and further estimate the passenger's weight. Once the passengers and their weights are determined, combined with their specific positions within the vehicle, the system generates a state map showing the distribution of seat positions and corresponding passenger weights. This step provides foundational data support for subsequent safety measures. The system monitors the vehicle's overall vibration values ​​in real time. If this value exceeds a set threshold, it indicates an impending accident. At this point, the system not only identifies the potential hazard but also calculates the optimal airbag deployment level for each seat based on this value. Considering the impact of passenger weight, seat position, and overall vehicle vibration, the system develops a personalized airbag deployment strategy for each seat. This customized approach ensures that each passenger receives the most suitable protection in the event of an accident.Based on all the above information (i.e., distribution map, comprehensive vibration values, airbag deployment levels for each seat, and sub-vibration data), the system generates and sends a smart terminal vehicle emergency call signal specifically for each passenger in their seat. The strength of the emergency call signal is directly related to the level of risk faced by the passenger; that is, the higher the risk (e.g., the greater the airbag deployment level or the more severe the sub-vibration data), the stronger the emergency call signal, thereby improving the targeting and efficiency of the rescue operation. In summary, through detailed analysis of passenger status and vehicle vibration conditions, this technical solution achieves precise control over the airbag deployment level and can adjust the strength of the vehicle emergency call signal according to the actual situation. Ultimately, it achieves the technical effect of improving the targeting and accuracy of emergency calls for vehicles involved in accidents, solving the technical problem of low targeting and accuracy of emergency calls for vehicles involved in accidents.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The terms "comprising" and "having," and any variations thereof, used in the embodiments of this application, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0024] Currently, the targeting and accuracy of emergency calls from accident-related vehicles are relatively low. Therefore, this application provides a method, device, and electronic device for emergency calls from intelligent terminal vehicles based on YTS (Smart Terminal System). This method can solve the technical problem of low targeting and accuracy in emergency calls from accident-related vehicles.

[0025] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0026] Figure 1 This is a flowchart illustrating a vehicle emergency call method based on YTS using a smart terminal, as provided in an embodiment of this application. Each seat in the vehicle is equipped with a shock absorber at a corresponding position; for example... Figure 1 As shown, the method includes the following steps: S110 collects sub-vibration data through multiple shock absorbers corresponding to multiple car seats, and determines whether there is a passenger in the car seat based on the sub-vibration data corresponding to each car seat.

[0027] The MCU communicates with all shock absorber nodes to verify ID, firmware version, and calibration coefficients. For example, with the vehicle stationary for 3 seconds, the no-load frequency response curve of each shock absorber is recorded as a "baseline template." The MCU broadcasts a sampling clock at 200 Hz; the 3-axis accelerometers built into each shock absorber synchronously acquire data. The nodes perform a 10-50 Hz bandpass filter + 50 Hz notch filter to remove inherent engine and tire noise. A frame (RMS_X, RMS_Y, RMS_Z, Peak-Peak, Spectral Entropy) is generated every 25 ms and sent back to the central ECU via LIN / CAN. The ECU subtracts the real-time frame from the baseline template to obtain ΔRMS, ΔPeak-Peak, and ΔEntropy. Feature_i = 0.6·ΔRMS + 0.3·ΔPeak-Peak + 0.1·ΔEntropy, where the weights are obtained through offline calibration and can be adjusted over-the-air (OTA). If Feature_i > TH_empty → occupied, then OccupiedFlag_i = 1; otherwise, = 0. The state is only flipped after three consecutive consistent frames to prevent false alarms due to bumps. When the vehicle speed > 15 km / h and Feature_i is within 5% of the threshold, "perturbation detection" is activated: a small 20 Hz excitation is injected within 0.5 s (driven in reverse by the shock absorber voice coil). If the change in ΔEntropy > 8%, a person is confirmed. The deviation between the total weight sensor (suspension master pump pressure) and Σ(OccupiedFlag_i × nominal passenger mass 75 kg) is < ±15 kg; otherwise, an abnormal seat is marked. OccupiedBitmap and confidence vector are sent to the BCM, ACU, and T-Box via CAN-FD. When the vehicle speed is 0 for 30 consecutive s and all doors are closed, all shock absorbers re-acquire baselines to compensate for temperature drift. A baseline refresh is triggered every 24 hours or when the temperature change exceeds 10°C. If a shock absorber does not respond within 500 ms, the seat status is set to "unknown," the instrument panel indicator lights up yellow, and the unknown seat is assumed to have a passenger in the collision algorithm, ensuring that the airbags fully deploy.

[0028] S120, if there are passengers in the car seats, the passenger weight in the car seats is detected according to the sub-vibration data, and the distribution map of the positions of multiple car seats and the corresponding passenger weights in the vehicle is generated by YTS according to the passenger weight and the position of the car seats in the vehicle; each car seat is equipped with at least one airbag.

[0029] In practical applications, YTS (Unity TV Service) refers to the Unity visualization rendering service system. Unity is a real-time 3D interactive content creation and operation platform, enabling creators in fields such as game development, art, architecture, automotive design, and film to turn their ideas into reality. The platform provides a complete software solution for creating, operating, and monetizing any real-time interactive 2D and 3D content, supporting platforms including mobile phones, tablets, PCs, game consoles, augmented reality, and virtual reality devices. The YTS engine is an intelligent engine system that deeply integrates AI algorithms, physical simulation, and 3D digital rendering technology, specifically designed for next-generation intelligent vehicles. Its core objective is to drive comprehensive upgrades in areas such as autonomous driving, vehicle-road collaboration, and intelligent interaction through high-precision simulation, real-time decision optimization, and cross-domain collaboration capabilities, building an integrated intelligent transportation ecosystem encompassing "people-vehicle-road-cloud."

[0030] As an optional implementation, for passenger presence checks, the OccupiedFlag_i from the previous process is used; only seats with Flag=1 are continued. For vehicle status verification, vehicle speed <5 km / h, steering wheel angle <10°, and suspension height change <3 mm are required to ensure quasi-static conditions; otherwise, weight measurement is delayed. The MCU sends a 40 Hz sinusoidal excitation (amplitude 0.3 mm) to the shock absorber voice coil for 200 ms. The displacement sensor (LVDT) synchronously records the 200 Hz displacement waveform d(t), and the accelerometer integrates to obtain the velocity v(t). According to F = m·a + c·v + k·d, the "effective added mass" m_i (i.e., passenger weight) is obtained by least-squares fitting. Temperature-stiffness compensation and lateral force coupling compensation are performed (by looking up the calibration table). If the fitting residual RMS < 5%, the confidence level Conf_i = 1; otherwise, Conf_i = max(0, 1 –RMS / 0.1). If m_i < 15 kg or > 150 kg, mark it as an outlier and use the most recent valid value. Obtain the seat geometry table SeatGeo[i] = {x_i, y_i, z_i} (ISO 8855 coordinate system) from the BCM. Weight_i = Conf_i × m_i. Push the structure YTS_Point { id, x, y, z, Weight_i, Conf_i} to the YTS. For thermal generation: Gaussian kernel density estimation σ = 0.15 m; color gradient: green (15 kg) → yellow (55 kg) → red (≥90 kg); overlay the seat frame mesh as a semi-transparent wireframe for easy viewing by the driver.

[0031] S130: Obtain the comprehensive vibration value of the vehicle. In response to the comprehensive vibration value being greater than the specified vibration data, determine that a vehicle accident is about to occur, and determine the airbag deployment level for each seat in advance based on the comprehensive vibration value and the distribution map.

[0032] Among them, the greater the comprehensive vibration value, the greater the sum of the airbag deployment degree; the greater the passenger weight in the distribution diagram, the greater the airbag deployment degree of the corresponding seat; and the closer the seat position is to the front of the vehicle in the distribution diagram, the greater the corresponding airbag deployment degree.

[0033] In one optional implementation, the airbag deployment level for each vehicle seat is determined in advance based on the comprehensive vibration values ​​and distribution map. This may specifically include the following steps: Based on the comprehensive vibration data and distribution map, the airbag deployment level for each car seat is determined in advance using the following formula:

[0034] in, This represents the overall vibration value; In the distribution state diagram, the first... i Each car seat corresponds to the passenger's weight; In the distribution state diagram, the first... j Each car seat corresponds to the passenger's weight; This indicates the position attenuation coefficient of the car seat; e It is a mathematical constant representing the base of the natural logarithm; In the distribution state diagram, the first... i Standardized position coefficients for each car seat; In the distribution state diagram, the first... k Each car seat corresponds to the passenger's weight; n This indicates the total number of seats in the vehicle. In the distribution state diagram, the first... k Standardized position coefficients for each car seat; This represents the vibration weighting coefficient; Indicates the weighting coefficient; Indicates the vibration gain coefficient; Indicates the degree of airbag deployment.

[0035] In this embodiment of the application, the calculation method of the above calculation formula makes the data on the airbag release degree for each car seat more accurate.

[0036] For example, when a collision occurs while a car is in motion, the airbag sensor first receives the impact signal. Once the impact intensity reaches a specified level, the sensor activates and sends a signal to the electronic controller. Upon receiving the signal, the electronic controller compares it with its previously stored signals. If the airbag deployment conditions are met, the drive circuit sends a start signal to the gas generator in the airbag assembly. Upon receiving the signal, the gas generator ignites the gas generator propellant, producing a large amount of gas. After filtration and cooling, the gas enters the airbag, causing it to rapidly deploy by breaking through the liner within a very short time. This forms an elastic air cushion in front of the driver or passenger, which then promptly leaks and contracts to absorb impact energy, effectively protecting the head and chest from injury or reducing the severity of injury.

[0037] For example, electronic airbags mainly consist of airbag sensors, anti-collision airbags, and electronic control devices. The driver-side anti-collision airbag is located in the steering wheel; the passenger-side anti-collision airbag is generally mounted on the dashboard. Airbag sensors are installed on the left, right, and center of the driver's compartment partition; the central airbag sensor and airbag system are integrated with the electronic control device. The airbag assembly mainly consists of the airbag, gas generator, and igniter. The electronic control device is used for data acquisition and processing, diagnosing the reliability of the airbag, ensuring timely ignition signals when preset values ​​are reached, and ensuring timely ignition to provide sufficient drive current to the gas generator.

[0038] S140 generates a smart terminal vehicle emergency call signal for each passenger in each seat based on the distribution state map, comprehensive vibration values, the deployment degree of each airbag, and sub-vibration data, and sends the smart terminal vehicle emergency call signal based on the vehicle accident.

[0039] Among them, the greater the airbag deployment degree and / or sub-vibration data, the stronger the emergency call signal from the smart terminal of the passenger in the car seat.

[0040] In this embodiment, each seat is first equipped with a shock absorber. These shock absorbers not only provide a comfortable riding experience but also collect sub-vibration data. Based on this data, the system can determine whether a passenger is present in each seat and further estimate the passenger's weight based on the sub-vibration data. Once the passengers and their weights in each seat are determined, combined with the passengers' specific positions in the vehicle, the system generates a state diagram of the distribution of seat positions and corresponding passenger weights. This step provides basic data support for subsequent safety measures. The system monitors the vehicle's overall vibration value in real time. If this value exceeds a set threshold, it indicates that an accident is imminent. At this time, the system not only identifies potential hazards but also calculates the optimal airbag deployment level for each seat based on this value. Considering the influence of passenger weight, seat position, and overall vehicle vibration, the system develops a personalized airbag deployment strategy for each seat. This customized approach ensures that each passenger receives the most suitable protection in the event of an accident. Based on all the above information (i.e., distribution map, comprehensive vibration values, airbag deployment levels for each seat, and sub-vibration data), the system generates and sends a smart terminal vehicle emergency call signal specifically for each passenger. The strength of the emergency call signal is directly related to the level of risk faced by the passenger; that is, the higher the risk (e.g., the greater the airbag deployment level or the more severe the sub-vibration data), the stronger the emergency call signal, thereby improving the targeting and efficiency of the rescue operation. In summary, through detailed analysis of passenger status and vehicle vibration conditions, this technical solution achieves precise control over the airbag deployment level and can adjust the strength of the vehicle emergency call signal according to the actual situation, ultimately achieving the technical effect of improving the targeting and accuracy of emergency calls for help from accident vehicles. This method not only improves passenger safety but also enhances the effectiveness of emergency response.

[0041] In some embodiments, a first distance sensor is provided at a corresponding position of each vehicle seat, and the sensing direction of the first distance sensor is towards the vehicle seat; after determining that a vehicle accident is about to occur in response to the comprehensive vibration value being greater than a specified vibration data, the method may further include the following steps: In response to a vehicle accident, the vehicle emits an emergency protection warning sound, which includes the corresponding emergency protection posture for the passenger. The first distance sensor detects whether the passenger's posture in the seat conforms to the specified emergency protection posture, and obtains the protection posture detection result. The above-mentioned method of determining the airbag deployment level for each vehicle seat in advance based on comprehensive vibration values ​​and distribution maps can specifically include the following steps: determining the airbag deployment level for each vehicle seat in advance based on comprehensive vibration values, distribution maps, and protective posture detection results; if the passenger posture in the protective posture detection results meets the specified emergency protective posture, then adjusting the airbag deployment level to decrease.

[0042] By combining comprehensive vibration data, passenger weight and position distribution maps, and passenger posture detection results, the system can provide a more personalized airbag deployment strategy for each passenger in each seat. In particular, when a passenger adopts the correct emergency protective posture, the system can appropriately reduce the degree of airbag deployment. This not only avoids secondary injuries that may be caused by excessive airbag deployment, but also ensures necessary protection.

[0043] Furthermore, the emergency protection alerts emitted by the vehicle include instructions on adopting designated emergency protection postures. This helps enhance passengers' self-protection awareness and ability in emergency situations, prompting them to react quickly and correctly before an accident, thereby reducing the risk of injury. A first distance sensor is used to monitor the posture of passengers in their seats in real time and dynamically adjusts the airbag deployment level based on the protection posture detection results. This method achieves an immediate feedback and response mechanism for passenger status, further enhancing the system's adaptability and effectiveness.

[0044] In some embodiments, the vehicle is equipped with multiple second distance sensors, with different second distance sensors facing different directions outside the vehicle; such as Figure 2 As shown, after determining that a vehicle accident is imminent, the method may further include the following steps: S210 detects multiple actual distances between the vehicle and external collisionable objects using multiple second distance sensors, as well as the rate of decrease in distance between the vehicle and external collisionable objects. S220, based on multiple actual distances and multiple distance reduction rates corresponding to the second distance sensors, determine the target second distance sensor corresponding to the first external collideable object that collided with the first from among the multiple second distance sensors; S230, determine the target position of the vehicle itself when a vehicle collision is about to occur based on the location of the second distance sensor on the vehicle; S240, based on the position of the vehicle seats in the distribution state diagram, determines the target airbag whose distance from the target position of the vehicle itself is less than a specified distance from the multiple airbags corresponding to the multiple vehicle seats, and controls the early release of the target airbag.

[0045] By using multiple secondary distance sensors to detect the actual distance between the vehicle and external potential collision objects and their rate of decrease, and determining the target position of the external object that will collide first and the corresponding position of the vehicle itself, the system can predict the impending collision location with great accuracy. This precision is crucial for ensuring that necessary protective measures are provided in the correct location.

[0046] Furthermore, based on the accurate prediction of the collision location, combined with the passenger distribution map inside the vehicle, the system can identify which passengers in which seats are most likely to be affected by the impact and deploy airbags in critical locations in advance. This method not only improves the efficiency of airbag deployment but also avoids unnecessary airbag deployment, reducing the potential risks to passengers caused by false airbag triggering or overuse.

[0047] By deploying airbags designed for specific locations in advance, this approach significantly enhances passenger protection. Especially in complex collision scenarios involving multiple directions and objects simultaneously, it more effectively addresses different types of impacts, providing more comprehensive protection for passengers.

[0048] In some embodiments, the above-mentioned determination of the airbag release level for each vehicle seat based on the comprehensive vibration value and the distribution state map may specifically include the following steps: determining the airbag release level for each vehicle seat in advance based on the distance between the vehicle seat and the target position of the vehicle itself, the comprehensive vibration value, and the distribution state map; the smaller the distance between the vehicle seat and the target position of the vehicle itself, the greater the airbag release level.

[0049] By considering factors such as the distance between the seat and the vehicle's target position, overall vibration data, and distribution patterns, the airbag deployment level is determined. This strategy allows the system to make an optimized response for the specific situation of each seat. For example, at a location closer to the point of impact, passengers may face a greater impact force, so the corresponding airbag will deploy to a greater extent, providing stronger cushioning protection.

[0050] Furthermore, traditional airbags typically deploy fully in a single, pre-set configuration, potentially causing unnecessary injury, especially for passengers not wearing seatbelts correctly or those with smaller builds. This solution, however, dynamically adjusts the inflation level of each airbag based on actual conditions, ensuring adequate protection when necessary while avoiding secondary injuries from over-inflation. Moreover, in multi-directional or multi-object collision scenarios, passengers in different seats may experience varying impact patterns and forces. Using the aforementioned method, the actual risk faced by each passenger can be more accurately assessed, and the airbag response level can be adjusted accordingly, making the entire protection system more intelligent and efficient.

[0051] In some embodiments, a seatbelt is provided at the corresponding position of each seat; after generating the distribution map of the positions and corresponding passenger weights of multiple seats in the vehicle using YTS based on passenger weight and the position of the seats in the vehicle, the method may further include the following steps: In response to a combined vibration value exceeding a specified vibration data point, the cushioning release level of the seatbelt for each seat is determined in advance based on the combined vibration value and the distribution map. The higher the combined vibration value, the lower the cushioning release level. In the distribution map, the greater the passenger weight, the greater the corresponding cushioning release level for the seat. The closer the seat is to the front of the vehicle in the distribution map, the lower the corresponding cushioning release level.

[0052] By combining vibration data and distribution patterns (including factors such as passenger weight and seat position), the system can provide customized seatbelt cushioning and release strategies for each passenger. This means that passengers of different weights and seat positions can receive the most suitable seatbelt protection for their individual circumstances, avoiding the potential for insufficient or excessive protection from a one-size-fits-all approach.

[0053] The higher the overall vibration value, the smaller the cushioning release. This is actually to prevent the seat belt from loosening prematurely in a severe collision, thus preventing greater injury to the passenger. Conversely, in the distribution diagram, the greater the passenger weight, the greater the corresponding cushioning release of the seat. This is to ensure that heavier passengers receive sufficient support and restraint during a collision, reducing injuries caused by inertia. The distribution diagram also shows that the closer the seat is to the front of the vehicle, the smaller the corresponding cushioning release, taking into account that front-seat passengers, compared to rear-seat passengers, face the impact force more directly in a frontal collision, thus requiring a tighter seat belt restraint to ensure safety.

[0054] This intelligent method of adjusting the seat belt's cushioning release not only takes into account the impact of collision intensity, but also fully considers the specific circumstances of the passengers (such as weight) and the characteristics of the seating layout, enabling the entire seat belt system to perform at its best in various complex situations, thereby significantly improving the overall safety of vehicle occupants.

[0055] In some embodiments, the above-mentioned response to a combined vibration value exceeding a specified vibration data point, determining in advance the cushioning release level of the seat belt for each vehicle seat based on the combined vibration value and the distribution map, may specifically include the following steps:

[0056]

[0057] in, Indicates the degree of cushioning release of the seat belt; This represents the overall vibration value; In the distribution state diagram, the first... i Each car seat corresponds to the passenger's weight; Indicates the nonlinearity of vibration; In the distribution state diagram, the first... i Normalized front and rear positions of each car seat; Indicates the weight sensitivity index; Indicates the position attenuation coefficient; Indicates the vibration suppression coefficient; Represents the global logarithmic decay coefficient; In the distribution state diagram, the first... k The normalized front and rear positions of each car seat.

[0058] In this embodiment of the application, the calculation method of the above calculation formula makes the data on the cushioning release degree of the seat belt for each car seat more accurate.

[0059] Figure 3 A schematic diagram of a YTS-based intelligent terminal vehicle emergency call device is provided. Each seat in the vehicle is equipped with a shock absorber at a corresponding position; such as... Figure 3 As shown, the YTS-based intelligent terminal vehicle emergency call device 300 includes: The acquisition module 301 is used to acquire sub-vibration data through multiple shock absorbers corresponding to multiple car seats, and to determine whether there is a passenger on the car seat based on the sub-vibration data corresponding to each car seat. The generation module 302 is used to detect the passenger weight of the passenger in the vehicle seat based on the sub-vibration data if there is a passenger in the vehicle seat, and generate a distribution map of the position and corresponding passenger weight of multiple vehicle seats in the vehicle through YTS based on the passenger weight and the position of the vehicle seat in the vehicle; each vehicle seat is provided with at least one airbag. The determination module 303 is used to acquire the comprehensive vibration value of the vehicle. In response to the comprehensive vibration value being greater than a specified vibration data, it determines that the vehicle is about to have a vehicle accident, and determines in advance the airbag deployment degree for each airbag corresponding to each seat based on the comprehensive vibration value and the distribution state diagram. The larger the comprehensive vibration value, the larger the sum of the deployment degrees of all the airbags. The greater the passenger weight in the distribution state diagram, the greater the deployment degree of the airbag corresponding to the seat. The closer the seat is to the front of the vehicle in the distribution state diagram, the greater the deployment degree of the corresponding airbag. The sending module 304 is used to generate a smart terminal vehicle emergency call signal for each passenger in each of the vehicle seats based on the distribution state map, the comprehensive vibration value, the deployment degree of each of the airbags, and the sub-vibration data, and to send the smart terminal vehicle emergency call signal based on the vehicle accident; the greater the airbag deployment degree and / or the sub-vibration data, the stronger the emergency call intensity of the smart terminal vehicle emergency call signal for the corresponding passenger in the vehicle seat.
