Description

Technical Field

[0001] The present application relates to the technical field of automobiles, and in particular to a HUD (English: Head-Up Display, Chinese: Head-Up Display) broken window reminder and system, and a readable storage medium. Background Art

[0002] In the automotive industry, when a vehicle is hit, there's insufficient escape space on the left side of the cab, and the door locks can't be opened. Escape is limited to knocking on the windshield. Typically, the escape impact points of a car's windshield are located around the edges, particularly at the four corners. In this situation, the driver can break the window and escape by knocking on the windshield's escape impact points.

[0003] Since the escape impact point of the windshield of existing vehicles is not clearly marked, the driver does not know the location of the glass impact point due to emergency situations or lack of escape experience, and cannot break the window and escape in time by accurately knocking on the escape impact point of the windshield. Summary of the Invention

[0004] In response to the problems existing in the existing technology such as the inability to accurately knock on the escape impact point of the front windshield to break the window and escape in time, the present application provides a HUD window breaking reminder method and system, and a readable storage medium. Combined with the E-CALL (English: Emergency Call, Chinese: Emergency Call) signal, the HUD system is used to identify and inform the user of the best window breaking position, which can effectively help the user break the window and escape, thereby increasing the user's escape probability.

[0005] In a first aspect, a HUD broken window reminder method is provided, which is applied to a vehicle. The method comprises: Determine whether the vehicle triggers the E-CALL signal; When the vehicle triggers the E-CALL signal, the HUD window-breaking reminder is triggered; After the HUD window-breaking reminder is triggered, the optimal knocking point for breaking the window is projected onto the front windshield through the HUD system.

[0006] When a vehicle collides, the E-CALL system will automatically trigger an E-CALL signal and send the accident information to the rescue center to ensure that rescue personnel can arrive at the scene quickly. For example: when a vehicle collides, the airbag pops out or the seat belt pretensioner is activated, the E-CALL system will automatically trigger an E-CALL signal and send an emergency call to the rescue center. In an embodiment of the present application, when it is determined that the vehicle has triggered the E-CALL signal, the HUD window breaking reminder is triggered. The HUD system projects the best knocking point for breaking the window on the front windshield, which can intuitively let the vehicle user know the best knocking point at the first time. When there is a crisis situation where the window must be broken (for example: the car door is blocked by an obstacle and cannot be opened), the window breaking position can be accurately found, so that the window can be broken, and an escape opportunity is obtained, thereby increasing the probability of escape.

[0007] In combination with the first aspect, in certain implementations of the first aspect, whether to trigger the E-CALL signal is determined according to the severity of the vehicle accident.

[0008] In the event of a vehicle collision, a minor collision, such as a minor vehicle scrape, may erroneously trigger an E-CALL signal, resulting in ineffective dispatch of rescue forces and a waste of rescue resources. In this embodiment of the present application, whether to trigger the E-CALL signal is determined based on the severity of the vehicle accident. Based on this judgment, the E-CALL signal is only triggered when the accident scenario reaches a certain level of danger. This allows limited rescue resources to be focused on the accident scene that truly requires emergency treatment, effectively avoiding the waste of rescue resources caused by erroneous triggering of the E-CALL signal and improving the efficiency of rescue resource utilization.

[0009] In conjunction with the first aspect, in certain implementations of the first aspect, a method for determining whether to trigger an E-CALL signal based on the severity of a vehicle accident is: When the degree of the vehicle accident is a common accident, it is determined that the vehicle does not trigger the E-CALL signal; when the degree of the vehicle accident is a serious accident, it is determined that the vehicle triggers the E-CALL signal.

[0010] In this embodiment, the severity of vehicle accidents is categorized into common and severe. Only when the accident is severe will the E-CALL signal be triggered. This automatically sends an emergency call to the rescue center, ensuring timely assistance. It also triggers a subsequent HUD window-breaking reminder, automatically displaying a warning on the windshield before help arrives, reminding the user to break the window and escape.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: when the vehicle encounters a collision, obtaining current vehicle condition information of the vehicle, and determining the severity of the vehicle accident based on the current vehicle condition information.

[0012] In an embodiment of the present application, when a vehicle encounters a collision, the severity of the vehicle accident is determined based on the vehicle's current vehicle condition information. The vehicle condition data can be collected and processed in real time at the moment of the collision (millisecond level), and the severity of the vehicle accident can be quickly determined, providing valuable time for subsequent emergency response, self-rescue and rescue.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the current vehicle condition information includes acceleration change information, and the degree of the vehicle accident is determined based on the acceleration change information.

[0014] In an embodiment of the present application, acceleration change information is used as a condition for judging the severity of a vehicle accident. The severity of a vehicle accident is judged by the acceleration change. The entire process from the occurrence of the accident to the output of the accident severity judgment result takes only a few seconds, and the severity of the vehicle accident can be judged quickly and accurately.

[0015] In conjunction with the first aspect, in certain implementations of the first aspect, a method for determining the severity of a vehicle accident based on acceleration change information is as follows: Determine whether the acceleration peak value is greater than or equal to the preset acceleration peak lower limit threshold; When the acceleration peak value is greater than or equal to the preset acceleration peak lower limit threshold, determine whether the acceleration peak value is greater than or equal to the preset acceleration peak upper limit threshold and lasts for a set time; When the acceleration peak is greater than or equal to the preset acceleration peak upper threshold and lasts for the set time, the vehicle accident level is determined to be a serious accident; when the acceleration peak is less than the preset acceleration peak threshold, or when the acceleration peak is greater than or equal to the preset acceleration peak upper threshold and does not last for the set time, the vehicle accident level is determined to be an ordinary accident.

[0016] In this embodiment of the application, by setting the upper and lower thresholds of the acceleration peak and the duration conditions, vehicle accidents can be accurately divided into two levels: serious accidents and ordinary accidents. This classification method avoids the situation in which the severity of vehicle accidents may be unclear in the past.

[0017] In combination with the first aspect, in certain implementations of the first aspect, the current vehicle condition information includes vehicle posture information, and the degree of the vehicle accident is determined based on the vehicle posture information.

[0018] The vehicle's posture can intuitively reflect the vehicle's rotation, tilt, and other states during an accident. In this embodiment of the present application, vehicle posture information is used as a condition for determining the severity of a vehicle accident. The entire process, from the occurrence of the accident to the output of the accident severity determination, takes only a few seconds, enabling a quick and accurate determination of the vehicle accident severity.

[0019] In conjunction with the first aspect, in certain implementations of the first aspect, a method for determining the severity of a vehicle accident based on vehicle posture information is as follows: Determine whether the vehicle's yaw angle is greater than or equal to a preset yaw angle threshold; When the vehicle yaw angle is greater than or equal to a set yaw angle threshold, determining whether the vehicle roll angle is greater than or equal to a preset roll angle threshold; When the vehicle roll angle is greater than or equal to a preset roll angle threshold, the vehicle accident is determined to be a serious accident; when the vehicle roll angle is less than the preset roll angle threshold, the vehicle accident is determined to be a common accident.

[0020] In the embodiment of the present application, two key parameters, namely the yaw angle and the roll angle, are introduced into the vehicle posture information. By setting the yaw angle threshold and the roll angle threshold conditions, a clear quantitative standard is provided for judging the degree of vehicle accidents. Vehicle accidents can be accurately divided into two levels: serious accidents and ordinary accidents, avoiding the unclear judgment of the degree of vehicle accidents that may have existed in the past.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: triggering an emergency call for rescue when it is determined that the vehicle triggers the E-CALL signal.

[0022] The vehicle will only trigger the E-CALL signal when it encounters a serious accident. In the embodiment of the present application, when it is determined that the vehicle has triggered the E-CALL signal, an emergency call for rescue is triggered, providing valuable time for subsequent emergency response and rescue, thereby improving the time for emergency rescue.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: before projecting the optimal striking point of the broken window on the front windshield through the HUD system, adjusting the projection angle of the HUD system imaging picture, and adjusting the position of the HUD system imaging picture to a preset position that directly displays the optimal striking point of the broken window.

[0024] During normal vehicle operation, the HUD system typically displays information in the center of the driver's field of view. This prevents the optimal impact point for window breaking from being directly displayed on the image. In the present embodiment, by adjusting the projection angle of the HUD system image, the HUD system image is positioned to a preset location that directly displays the optimal impact point for window breaking. This intuitively indicates the driver the most appropriate window breaking location, maximizing their chances of escape.

[0025] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: when the optimal knocking point for breaking the window is projected onto the front windshield through the HUD system, generating text information and sending it to the HUD system, and projecting the text information onto the front windshield through the HUD system.

[0026] In an embodiment of the present application, when the optimal striking point for breaking a window is projected onto the windshield via the HUD system, a text message is generated and sent to the HUD system. The text message, projected onto the windshield by the HUD system, can remind the user what tool to use as a window breaker if a window breaker is unavailable, thereby increasing the user's chances of escaping through the window. For example, the text message could read: "If sharp or blunt objects are unavailable, the headrest bracket can also be used as a window breaker."

[0027] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: when the optimal knocking point for breaking the window is projected on the front windshield through the HUD system, a window breaking escape guidance video is played through the HUD system, or the HUD system and the vehicle's central control screen, or the vehicle's central control screen.

[0028] In the event of a serious collision, even if the optimal striking point for breaking the window is projected on the windshield, some drivers may still not know how to break the window due to panic or lack of experience. In this embodiment of the present application, while the optimal striking point for breaking the window is projected on the windshield via the HUD system, a window-breaking escape instruction video is also played via the HUD system and the vehicle's central control screen to guide the driver in breaking the window.

After receiving the text information, the projection module projects the text information onto the front windshield.

[0038] In combination with the second aspect, in certain implementations of the second aspect, the HUD system further includes a storage module, which is used to store preset text information; the storage module is connected to the projection module, and the storage module is configured to: when the best knocking point for breaking the window is projected on the front windshield through the HUD system, send the text information to the projection module so as to be projected onto the front windshield through the projection module.

The HUD video playback module is used to play a window-breaking escape guidance video and transmit the playback content to the projection module. After receiving the playback content, the projection module projects the playback content onto the front windshield.

[0043] In combination with the second aspect, in certain implementations of the second aspect, the HUD video playback module is configured to start playing the window-breaking escape guidance video when the HUD system projects the optimal knocking point for breaking the window onto the front windshield.

DETAILED DESCRIPTION

[0058] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0059] In the embodiments of the present application, prefixes such as "first" and "second" are used only to distinguish different description objects and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers to distinguish description objects in the embodiments of the present application does not constitute a restriction on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and the use of such prefixes should not constitute an unnecessary restriction. In addition, in the description of this embodiment, unless otherwise specified, the meaning of "plurality" is two or more.

[0060] The following describes the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents "or." For example, A / B can represent A or B. "And / or" in this document is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, or B exists alone.

[0061] In the several embodiments provided in the embodiments of the present application, it should be understood that the disclosed systems and methods can be implemented in other ways. For example, the device embodiments described above are merely schematic. For example, the division of the units is merely a logical function division. In actual implementation, there may be other division methods, such as multiple units or components can be combined or integrated into another system, or some features can be ignored or not executed. Another point is that the mutual coupling or direct coupling or communication connection shown or discussed can be an indirect coupling or communication connection of some interfaces, devices or units, which can be electrical, mechanical or other forms.

[0062] With the continued growth of vehicle ownership and the inherent risk of vehicle accidents, emergency escape after a collision has become a crucial issue for the safety of drivers and passengers. When a vehicle is involved in a collision and the left side of the cab is missing escape space due to deformation, obstructions, or other factors, and the door locks are unable to open due to the impact, tapping on the windshield becomes a key means of escape.

[0063] However, most car windshields currently use laminated glass, a composite of multiple layers of glass and PVB film. This provides high impact strength and toughness, significantly increasing the difficulty of breaking windows. The edges of car windshields, particularly the corners, are structurally weaker than the center. This is because during the glass production process, stress distribution at the edges differs from that in the center, and during installation, the edges are subject to greater external forces, resulting in a relatively lower strength.

[0064] In real-world emergency situations, although the edges and corners of the windshield are theoretically the optimal impact points, existing vehicles generally lack clear markings on these critical escape impact points. Drivers often struggle to quickly identify and accurately locate the effective impact zone due to panic and inexperience, resulting in a significant waste of time and energy in the striking process. Repeated striking of ineffective areas (for example, the center of the windshield) can even lead to missed escape opportunities. Furthermore, some drivers lack understanding of the structural properties of laminated glass and employ incorrect striking techniques (such as continuously striking the center of the windshield), further delaying escape attempts. These issues severely limit the efficiency and success rate of windshield-breaking escape attempts in emergencies.

[0065] Based on the above application scenarios, this application proposes a HUD broken window reminder method.

[0066] Figure 1 This is a schematic flow chart of a HUD broken window reminder method provided in this embodiment. The method is applicable to vehicles and includes the following steps.

[0067] S1. Determine whether the vehicle triggers an E-CALL signal.

[0068] In one embodiment of the present application, whether to trigger the E-CALL signal is determined according to the severity of the vehicle accident.

[0069] The E-CALL system is a vehicle emergency call system that automatically or manually triggers an emergency call in the event of a vehicle accident, transmitting accident information to a rescue center for rapid assistance. Typically, when a vehicle is severely deformed in a collision, the E-CALL system uses multiple sensors and algorithms to determine the severity of the accident and then automatically triggers an E-CALL signal based on the severity. For example, when a vehicle collides, the collision sensor detects signals such as the impact force. If a preset threshold is reached, such as when the vehicle's airbag deploys, the E-CALL system automatically triggers the E-CALL signal. Another example is when a vehicle is in a serious accident and the door locks cannot be opened, requiring assistance.

[0070] It should also be noted that when a vehicle collision occurs, there may be ordinary accidents such as minor vehicle scratches that mistakenly trigger the E-CALL signal, resulting in the ineffective dispatch of rescue forces and a waste of rescue resources.

[0071] In an embodiment of the present application, whether to trigger the E-CALL signal is determined according to the severity of the vehicle accident. After making a judgment based on the severity of the vehicle accident, the E-CALL signal will only be triggered when the accident scenario reaches a certain level of danger. On the one hand, limited rescue resources can be concentrated on the accident scene that really needs emergency treatment. On the other hand, it can effectively avoid the waste of rescue resources caused by the false triggering of the E-CALL signal, thereby improving the utilization efficiency of rescue resources.

[0072] In one embodiment of the present application, the method for determining whether to trigger the E-CALL signal according to the degree of the vehicle accident is: when the degree of the vehicle accident is an ordinary accident, determining that the vehicle does not trigger the E-CALL signal; when the degree of the vehicle accident is a serious accident, determining that the vehicle triggers the E-CALL signal.

[0073] It should be noted that a normal accident involves a minor collision or scrape, with no significant structural deformation, no serious injuries to the driver or passengers, and the vehicle remaining drivable or requiring only minor repairs. For example, a minor collision may result in a damaged headlight or a dented door, but the door will open normally. Another example is a minor collision where the front bumper is damaged but the structure remains intact. Another example is a scrape where scratches appear on the vehicle body. A serious accident involves a severe collision, rollover, or severe deformation, potentially resulting in serious injuries to the driver and passengers, making the vehicle unable to operate normally and requiring emergency assistance. For example, a severe collision may result in the vehicle starting up despite damage, but still operating normally. Another example is a severe collision where a door becomes twisted and deformed, preventing it from opening. Another example is a rollover where the door is blocked and cannot be opened.

[0074] In the embodiment of the present application, the degree of the vehicle accident is divided into ordinary accidents and serious accidents. When the degree of the vehicle accident is an ordinary accident, it is determined that the vehicle does not trigger the E-CALL signal. When the degree of the vehicle accident is a serious accident, it is confirmed that the vehicle triggers the E-CALL signal. On the one hand, only when the degree of the vehicle accident is a serious accident will the E-CALL signal be triggered, and an emergency call will be automatically sent to the rescue center so that rescue can be obtained in time, so that limited rescue resources can be concentrated on the accident scene that really needs emergency treatment. On the other hand, it can trigger the subsequent HUD broken window reminder, and automatically give a prompt on the front windshield before the rescue arrives, reminding the user to break the window to escape. On the other hand, it can effectively avoid the waste of rescue resources caused by the wrong triggering of the E-CALL signal, and improve the utilization efficiency of rescue resources.

[0075] For example, when a user is driving, he encounters snowy weather, the road is icy and slippery, the vehicle skids, and hits a roadside obstacle, causing the left side of the vehicle's cab to be severely deformed, the door cannot be opened, and the vehicle cannot be driven. This is a serious accident. At this time, the vehicle triggers the E-CALL signal and automatically sends an emergency call to the rescue center.

[0076] For example, when a user is driving, a serious collision occurs with a vehicle changing lanes on the side, causing the vehicle body structure to be severely deformed and the vehicle to be unable to drive normally. This is a serious accident. At this time, the vehicle triggers the E-CALL signal and automatically sends an emergency call to the rescue center.

[0077] For example, while driving, the user rear-ends the vehicle at a traffic light intersection, resulting in a minor collision. Cracks appear on the front bumper of the vehicle, but the vehicle can still drive normally. This is a normal accident, and the vehicle does not trigger the E-CALL signal.

[0078] In one embodiment of the present application, the method further includes: when the vehicle encounters a collision, obtaining current vehicle condition information of the vehicle, and determining the severity of the vehicle accident based on the current vehicle condition information.

[0079] When a vehicle is hit, the vehicle's current condition information can well characterize the severity of the vehicle accident. In the embodiments of the present application, when a vehicle is hit, the severity of the vehicle accident is determined based on the vehicle's current condition information. This allows for real-time acquisition and processing of vehicle condition data at the instant of collision (in milliseconds), allowing for a rapid determination of the severity of the vehicle accident, providing valuable time for subsequent emergency response, self-rescue, and rescue efforts.

[0080] In the embodiment of the present application, in some specific implementations, the current vehicle condition information includes acceleration change information, and the degree of the vehicle accident is determined based on the acceleration change information.

[0081] When a vehicle is severely impacted and deformed, the acceleration sensor will record the peak acceleration. The magnitude and changing trend of the peak acceleration can serve as one of the important criteria for determining the severity of the vehicle accident. In the embodiment of the present application, the acceleration change information is used as a condition for determining the severity of the vehicle accident. The entire process from the occurrence of the accident to the output of the accident severity judgment result takes only a few seconds. This can quickly and accurately determine the severity of the vehicle accident, saving time for subsequent emergency response, self-rescue, and rescue, and increasing the probability of escape.

[0082] Specifically, acceleration sensors installed at different locations on the vehicle can be used to detect acceleration change information generated when the vehicle encounters a collision, thereby determining the severity of the vehicle accident based on the acceleration change information.

[0083] Specifically, see Figure 2 ,The method for judging the degree of vehicle accident based on acceleration change information is: S111, determining whether the acceleration peak value is greater than or equal to a preset acceleration peak lower limit threshold; S112: When the acceleration peak value is greater than or equal to the preset acceleration peak lower limit threshold, determine whether the acceleration peak value is greater than or equal to the preset acceleration peak upper limit threshold and whether the value remains greater than or equal to the preset acceleration peak upper limit threshold for a set time; S113. When the acceleration peak value is greater than or equal to the preset acceleration peak upper threshold value and lasts for the set time, the degree of the vehicle accident is determined to be a serious accident; when the acceleration peak value is less than the preset acceleration peak threshold value, or when the acceleration peak value is greater than or equal to the preset acceleration peak upper threshold value and does not last for the set time, the degree of the vehicle accident is determined to be an ordinary accident.

[0084] In the embodiment of the present application, by setting upper and lower thresholds for the acceleration peak value and duration conditions, vehicle accidents can be accurately classified into two levels: severe accidents and ordinary accidents. This classification method avoids the unclear judgment of the severity of vehicle accidents that may have existed in the past. It provides a guarantee for the subsequent confirmation of whether to trigger the E-CALL signal based on the severity of the vehicle accident. The E-CALL signal can be triggered when the vehicle accident is severe, effectively avoiding the waste of rescue resources caused by the false triggering of the E-CALL signal and improving the utilization efficiency of rescue resources.

[0085] For example, during normal driving, the peak acceleration is less than 5g, the lower limit is set to 5g, the upper limit is set to 30g, and the duration is set to 50ms. When the vehicle is struck by a severe collision, the acceleration sensor detects a peak acceleration of 35g for 55ms. Since the peak acceleration exceeds the preset upper limit, far exceeding the normal driving range (less than 5g), the vehicle accident is considered severe. When the vehicle accident is considered severe, the E-CALL system triggers an E-CALL signal, which automatically sends an emergency call to the rescue center to ensure timely assistance. It also triggers a subsequent HUD window break reminder, automatically displaying a warning on the windshield before help arrives, reminding the user to break the window and escape.

[0086] For example, during normal driving, the peak acceleration is less than 5g, the lower limit of the peak acceleration is set to 5g, the upper limit of the peak acceleration is set to 30g, and the duration is set to 50ms. If the vehicle suffers a severe collision, the peak acceleration detected by the accelerometer is 35g and lasts for 10ms. Although the acceleration value detected by the accelerometer exceeds the preset upper limit of the peak acceleration, the duration is less than the set time. In this case, the vehicle accident is classified as a moderate accident. If the vehicle accident is classified as a moderate accident, the E-CALL system does not trigger the E-CALL signal, effectively avoiding the waste of rescue resources caused by the erroneous triggering of the E-CALL signal and improving the efficiency of rescue resource utilization.

[0087] For example, during normal driving, the peak acceleration is less than 5g, the lower limit of the peak acceleration is set to 5g, the upper limit of the peak acceleration is set to 30g, and the duration is set to 50ms. When the vehicle is struck, the peak acceleration detected by the accelerometer is 10g, and the duration is 10ms. Since the acceleration value detected by the accelerometer is greater than the preset lower limit of the peak acceleration, but less than the preset upper limit of the peak acceleration, and far exceeds the range during normal driving, the severity of the vehicle accident is considered a moderate accident. When the vehicle accident severity is considered a moderate accident, the E-CALL system does not trigger the E-CALL signal, effectively avoiding the waste of rescue resources caused by the erroneous triggering of the E-CALL signal and improving the efficiency of rescue resource utilization.

[0088] In the embodiment of the present application, in some specific implementations, the current vehicle condition information includes vehicle posture information, and the degree of the vehicle accident is determined based on the vehicle posture information.

[0089] In an embodiment of the present application, vehicle posture information is used as a condition for judging the severity of a vehicle accident. The severity of a vehicle accident is judged by changes in vehicle posture. The entire process from the occurrence of an accident to the output of the accident severity judgment result takes only a few seconds, and the severity of a vehicle accident can be judged quickly and accurately.

[0090] Specifically, the posture information of the vehicle after the collision can be detected by a gyroscope sensor, so as to determine the severity of the vehicle accident based on the posture information.

[0091] Specifically, see Figure 3 ,The method for judging the degree of vehicle accident based on posture information is: S121, determining whether the vehicle yaw angle is greater than or equal to a preset yaw angle threshold; S122. When the vehicle yaw angle is greater than or equal to a set yaw angle threshold, determining whether the roll angle is greater than or equal to a preset roll angle threshold; S123: When the roll angle is greater than or equal to a preset roll angle threshold, determine that the vehicle accident is a serious accident; when the roll angle is less than the preset roll angle threshold, determine that the vehicle accident is a common accident.

[0092] The yaw angle is the angle of rotation of the vehicle around its vertical axis, that is, the degree to which the vehicle turns left or right. When the vehicle turns right, the yaw angle is positive; when the vehicle turns left, the yaw angle is negative. The positive and negative definitions of the yaw angle can be determined according to the right-hand rule, that is, with the vehicle's vertical axis as the positive direction, the four fingers of the right hand pointing to the right side of the vehicle, and the thumb pointing to the front of the vehicle. When the vehicle turns right, the yaw angle is positive. The roll angle is the angle of rotation of the vehicle around its longitudinal axis, that is, the degree to which the vehicle tilts left or right. When the vehicle tilts to the right, the roll angle is positive; when the vehicle tilts to the left, the roll angle is negative. The positive and negative definitions of the roll angle can be determined according to the right-hand rule, that is, with the vehicle's longitudinal axis as the positive direction, the four fingers of the right hand pointing to the upper side of the vehicle, and the thumb pointing to the right side of the vehicle. When the vehicle tilts to the right, the roll angle is positive.

[0093] The yaw angle and roll angle can intuitively reflect the rotation and tilt state of the vehicle in the accident. In the embodiment of the present application, the two key parameters of the yaw angle and roll angle are introduced in the vehicle posture information. By setting the yaw angle threshold and the roll angle threshold conditions, a clear quantitative standard is provided for the judgment of the degree of vehicle accidents, and vehicle accidents can be accurately divided into two levels: serious accidents and ordinary accidents. This grading method avoids the situation where the judgment of the degree of vehicle accidents may be unclear in the past. It provides a guarantee for the subsequent confirmation of whether to trigger the E-CALL signal according to the degree of the vehicle accident, and can trigger the E-CALL signal when the degree of the vehicle accident is a serious accident, effectively avoiding the waste of rescue resources caused by the wrong triggering of the E-CALL signal, and improving the utilization efficiency of rescue resources.

[0094] It should be noted that when the vehicle is driving normally, the yaw angle is usually kept within ±3°. When the vehicle turns slightly, the yaw angle may reach ±5°. In extreme cases (for example, the vehicle suddenly encounters an obstacle in front and the driver quickly turns the steering wheel to avoid it), it may reach ±10°. Therefore, when setting the yaw angle threshold, it can be set according to the yaw angle range that may occur during normal driving. When the vehicle is driving normally, if the vehicle is driving in a straight line, the roll angle is usually close to 0°, that is, the body remains basically level. If the vehicle turns, the roll angle may reach ±10°, and in extreme cases it may reach ±15°. Therefore, when setting the roll angle threshold, it can be set according to the roll angle range that may occur during normal driving.

[0095] For example, the yaw angle threshold is set to 10° and the roll angle threshold is set to 45°. When the vehicle is hit, the gyroscope sensor detects a yaw angle of 30° and a roll angle of 30°. Because the yaw angle is greater than the yaw angle threshold and the roll angle is less than the roll angle threshold, the vehicle accident severity is determined to be a moderate accident.

[0096] For example, the yaw angle threshold is set to 10° and the roll angle threshold is set to 45°. When the vehicle is impacted, the gyroscope sensor detects a yaw angle of 30° and a roll angle of 60°. Because the yaw angle is greater than the yaw angle threshold and the roll angle is greater than the roll angle threshold, the vehicle accident severity is determined to be severe.

[0097] S2. When it is determined that the vehicle triggers the E-CALL signal, trigger the HUD broken window reminder.

[0098] A HUD system is a display system that projects important driving information onto the front windshield in front of the driver, allowing the driver to access key information without looking down at the instrument panel. In an embodiment of the present application, when the vehicle triggers an E-CALL signal, a HUD window-breaking reminder is triggered. The combination of the E-CALL signal and the HUD window-breaking reminder provides a prerequisite for subsequent HUD system guidance on the window-breaking reminder. Only when the vehicle triggers both the E-CALL signal and the HUD window-breaking reminder does the HUD system project the optimal striking point for breaking the window onto the front windshield, intuitively letting the vehicle user know the optimal striking point immediately. If the vehicle is hit and the driver lacks sufficient escape space on the left and cannot open the door, and before help arrives, the driver can accurately locate the broken window based on the HUD system's display prompts, perform self-rescue actions, and then break the window to escape, thereby increasing their chances of escape.

[0099] S3. After the HUD window-breaking reminder is triggered, the optimal striking point for breaking the window is projected onto the front windshield through the HUD system.

[0100] In an embodiment of the present application, after the HUD window breaking reminder is triggered, the optimal knocking point for breaking the window is projected on the front windshield through the HUD system, so that the vehicle user can intuitively know the optimal knocking point at the first time. When there is a crisis situation where the window must be broken (for example: the vehicle is severely hit, the door is blocked by an obstacle and cannot be opened, and breaking the door and window is impossible to escape), the window breaking position can be accurately found, so that the window can be broken by knocking on the window breaking position, thereby obtaining an escape opportunity and increasing the probability of escape.

[0101] It's important to note that the escape impact points for a car's windshield are primarily located around the edges, particularly at the top left, bottom left, top right, and bottom right corners. When breaking a window, the driver's side of the windshield is optimally impacted at the bottom left corner. Therefore, the HUD system is configured to prioritize projecting the optimal impact point at the bottom left corner of the windshield.

[0102] Specifically, the optimal tapping point can be displayed in the form of an icon. The icon is projected directly onto the optimal tapping point. When breaking the window, the user can simply tap the location indicated by the icon. The optimal tapping point can also be displayed in text form, for example: Tap the lower left corner of the front windshield to break the window and escape.

[0103] In one embodiment of the present application, the method further includes: before projecting the optimal striking point of the broken window on the front windshield through the HUD system, adjusting the projection angle of the HUD system imaging screen, and adjusting the position of the HUD system imaging screen to a preset position that directly displays the optimal striking point of the broken window.

[0104] It's important to note that there are many different types of HUD systems, each with varying screen sizes. For example, a W-HUD (Windshield Head-Up Display) system uses a projector to project images onto the windshield, leveraging the glass's reflective properties to create a virtual image (i.e., the image), allowing the driver to view information without lowering their head. The image is typically displayed directly in front of the driver on the windshield, roughly parallel to the road, minimizing eye movement. The W-HUD system's image area is very small, with a field of view of approximately 5° × 2°. AR-HUD (Augmented Reality Head-Up Display) systems are a new generation of in-vehicle HUD systems that integrate augmented reality technology with traditional HUD systems (i.e., W-HUD systems), blending virtual information with real-world road conditions. AR-HUD systems have a larger image area, with a field of view ranging from 10° × 4° to 20° × 8°. A P-HUD (projected head-up display) system uses projection technology to project driving information directly onto the windshield or a dedicated transparent screen. The P-HUD system's image is typically displayed in a black area at the bottom of the windshield. The P-HUD system's image area is smaller than that of an AR-HUD system, but larger than that of a W-HUD system. The P-HUD system's field of view is approximately 5° × 2°, similar to that of a W-HUD system, and the display area is concentrated slightly below the center of the driver's field of view. On some models, the P-HUD system can only be projected below the windshield.

[0105] Therefore, under normal circumstances, when displaying information, the HUD system generally displays it in the center of the driver's field of view, and is unable to directly display the optimal impact point for breaking the window on the image. In the embodiment of the present application, by adjusting the projection angle of the HUD system image, the position of the HUD system image is adjusted to a preset position that directly displays the optimal impact point for breaking the window. This can intuitively prompt the driver to the most appropriate window breaking position, maximizing their chances of escape.

[0106] For example, the HUD system of a certain vehicle is a W-HUD system. When the vehicle is severely hit, the door is severely deformed and the door lock cannot be opened, and the vehicle triggers the E-CALL signal. When it is confirmed that the vehicle has triggered the E-CALL signal, the HUD broken window reminder is triggered. After the HUD broken window reminder is triggered, the W-HUD system automatically adjusts the projection angle of the W-HUD system imaging screen and adjusts the position of the W-HUD system imaging screen to the preset position that directly displays the best knocking point for breaking the window. It should be noted that since the area of the W-HUD system imaging screen is very small, the best knocking point for breaking the window is displayed by pointing with an arrow.

[0107] For example, the HUD system of a certain vehicle is an AR-HUD system. When the vehicle is severely hit, the door is severely deformed and the door lock cannot be opened, and the vehicle triggers the E-CALL signal. When it is confirmed that the vehicle has triggered the E-CALL signal, the HUD broken window reminder is triggered. After the HUD broken window reminder is triggered, the AR-HUD system automatically adjusts the projection angle of the AR-HUD system imaging screen, and the position of the AR-HUD system imaging screen is adjusted to the preset position that directly displays the best knocking point for breaking the window. It should be noted that due to the large area of the AR-HUD system imaging screen, after the imaging screen is adjusted, the imaging screen can cover the best knocking point for breaking the window, and the best knocking point for breaking the window can be directly displayed through an icon (for example: dot, asterisk, etc.).

[0108] For example, the HUD system of a certain vehicle is a P-HUD system. When the vehicle is severely impacted, the door is severely deformed and the door lock cannot be opened, and the vehicle triggers the E-CALL signal. When it is confirmed that the vehicle has triggered the E-CALL signal, the HUD window-breaking reminder is triggered. After the HUD window-breaking reminder is triggered, the P-HUD system automatically adjusts the projection angle of the P-HUD system imaging screen, and the position of the P-HUD system imaging screen is adjusted to the preset position that directly displays the best knocking point for breaking the window. Since the imaging screen of the P-HUD system is adjusted, the imaging screen can cover the best knocking point for breaking the window, and the best knocking point for breaking the window can be directly displayed through an icon (for example: dot, asterisk, etc.). It should be noted that since the projection position of the P-HUD system of some models can only be below the front windshield, the user can be informed of the best knocking point by a text prompt below the front windshield to knock on the edge of the glass.

[0109] In one embodiment of the present application, the method further includes: when the optimal knocking point for breaking the window is projected onto the front windshield through the HUD system, generating text information and sending it to the HUD system, and projecting the text information onto the front windshield through the HUD system.

[0110] When a vehicle is hit and there is insufficient escape space on the left side of the cab, and the door cannot be opened, the only way to escape is by hitting the windshield to break the window. However, due to the emergency situation or lack of escape experience, even if the driver knows the optimal striking point on the windshield to break the window, he or she may panic because there is no window breaker nearby and may not know what tool to use to quickly break the window. In an embodiment of the present application, when the optimal striking point is projected onto the windshield via the HUD system, a text message is generated and sent to the HUD system. The HUD system then projects the text message onto the windshield, reminding the user through the text message which tool can be used as a window breaker, thereby increasing the user's chances of escaping by breaking the window.

[0111] For example, the text message may be: If you don't have a window breaker, sharp objects, or blunt objects, you can also use the seat headrest bracket as a window breaker. The text message may also be: If you don't have a window breaker, sharp objects, or blunt objects, you can also use the seat headrest bracket as a window breaker. How to use it: Directly pull out the seat headrest bracket and use it to hit the optimal striking point.

[0112] For example, the text message could be: If you don't have a window breaker, sharp objects, or blunt objects, you can use the metal buckle of the seat belt receptacle as a window breaker. The text message could also be: If you don't have a window breaker, sharp objects, or blunt objects, you can use the metal buckle of the seat belt receptacle as a window breaker. To use it, unbuckle your seat belt, hold one end of the metal buckle, and strike the optimal striking point with the tip or corner (the force should be continuous and concentrated).

[0113] For example, the text message may be: If you do not have a window breaker, sharp object, or blunt object, you can use the heel of your shoe as a window breaker. This text message is applicable to drivers wearing high heels (with metal or hard plastic heels) or leather shoes.

[0114] It should be noted that the text information can be information pre-set and stored in the memory. When the best knocking point for breaking the window is projected onto the windshield through the HUD system, the HUD system can obtain the text information from the memory and project it onto the windshield.

[0115] In one embodiment of the present application, the method further includes: when the optimal knocking point for breaking the window is projected on the front windshield through the HUD system, generating text information and sending it to the vehicle's central control screen, and displaying the text information through the vehicle's central control screen.

[0116] In one embodiment of the present application, the method further includes: when the optimal knocking point for breaking the window is projected on the front windshield through the HUD system, a window breaking escape guidance video is played through the HUD system, or the HUD system and the vehicle's central control screen, or the vehicle's central control screen.

[0117] When a vehicle is involved in a collision or an emergency (e.g., a vehicle falling into water, a fire, or the absence of a physical key), and the driver is unable to open the door, they may not know how to break a window to escape due to lack of escape experience. In an embodiment of the present application, while the optimal striking point for breaking a window is projected onto the front windshield via the HUD system, a window-breaking escape instruction video is played via the HUD system, or the HUD system and the vehicle's central control screen, or the vehicle's central control screen, to guide the driver through the window-breaking operation. This effectively prevents the driver from delaying escape due to ignorance of how to break a window and making random attempts, resulting in a failure to break a window in time and even endangering their life.

[0118] In the embodiments of the present application, in some specific implementations, when the optimal knocking point for breaking the window is projected onto the front windshield through the HUD system, only the window breaking escape guidance video is played through the HUD system, and the video content is projected onto the front windshield to guide the driver to perform the window breaking operation.

[0119] In the embodiments of the present application, in some specific implementations, when the optimal knocking point for breaking the window is projected on the front windshield through the HUD system, only the window breaking escape guidance video is played through the vehicle's central control screen to guide the driver to perform the window breaking operation.

[0120] In some embodiments of the present application, when the optimal striking point for breaking a window is projected onto the windshield via the HUD system, a window-breaking escape instruction video is played via the HUD system, with the video content projected onto the windshield to guide the driver through the window-breaking maneuver. Simultaneously, the window-breaking escape instruction video is played on the vehicle's central control screen to guide the driver through the window-breaking maneuver. This allows users to view the window-breaking escape instruction video from different angles.

[0121] In one embodiment of the present application, a collision monitoring module provided on the vehicle monitors the current vehicle condition information of the vehicle in real time, and sends the monitored current vehicle condition information of the vehicle to the smart cockpit terminal. The smart cockpit terminal determines whether to trigger an E-CALL signal based on the current vehicle condition information. When the smart cockpit terminal determines that the vehicle triggers the E-CALL signal, the smart cockpit terminal triggers a HUD broken window reminder. After the smart cockpit terminal triggers the HUD broken window reminder, the best knocking point for breaking the window is projected onto the front windshield through the HUD system.
