[0002] With the rapid development of the domestic automobile market, consumers have increasingly high requirements for vehicle comfort and technical configuration. In medium and high-end vehicles, ceiling screens, as emerging in-vehicle information and entertainment devices, are gradually becoming standard or optional configurations, providing passengers with video, navigation, entertainment and other functions.

[0003] However, while enjoying the convenience brought by technology, the potential safety hazards of ceiling screens in vehicle collisions or accidents have gradually emerged. If effective safety protection measures are lacking, ceiling screens may cause secondary injuries to passengers in an accident. Therefore, how to provide entertainment functions while ensuring the safety of passengers in the vehicle has become a technical problem to be solved. SUMMARY

[0004] The present application provides a danger warning and defense method and system for a vehicle ceiling screen, a storage medium and a vehicle to solve the above technical problems.

[0005] Specifically, the present application provides a danger warning and defense method, wherein a current vehicle is configured with at least one gyroscope and at least one ceiling screen; the danger warning and defense method comprises the following steps:

[0006] S100: Real-time acquisition of detection values of the gyroscope of the current vehicle.

[0007] S200: Obtaining the driving danger level of the current vehicle according to the detection values.

[0008] S300: Based on the driving danger level, controlling the ceiling screen to broadcast a corresponding warning picture, or based on the driving danger level and the detection values, controlling the ceiling screen to broadcast a corresponding warning picture and rotate to a corresponding angle.

[0009] In the above technical solution, by real-time acquisition of detection values of the gyroscope of the vehicle, dynamic changes of the vehicle, such as dangerous driving behaviors such as sharp turns, rapid acceleration and rapid braking, can be accurately captured, thereby realizing real-time monitoring and early warning of driving risks; according to different driving danger levels, corresponding visual warning information such as color change, icon display and text prompt is provided to ensure that members can obtain different levels of warning according to the danger level, which helps members to take timely measures; in the event of a collision or accident, the system can adjust the posture of the ceiling screen according to the actual situation to avoid secondary injuries to passengers in the vehicle caused by the fixed ceiling screen, for example, the ceiling screen can be automatically adjusted to a safe position in the event of a collision.

[0010] Further, the detection values at least include acceleration and angular velocity; the acceleration at least includes X-axis acceleration, Y-axis acceleration and Z-axis acceleration; and the angular velocity at least includes X-axis angular velocity, Y-axis angular velocity and Z-axis angular velocity.

[0011] Wherein, the current vehicle advancing direction is the positive direction of the X-axis, the right side of the current vehicle advancing direction is the positive direction of the Y-axis, and the direction in which the current vehicle bounces upward is the positive direction of the Z-axis.

[0012] In the above technical solution, through detailed detection of the acceleration and angular velocity in the X, Y and Z directions, the motion state of the vehicle can be comprehensively captured, such as sharp turning, sudden braking and bouncing, so that the current driving risk level can be more accurately judged; based on detailed acceleration and angular velocity data, the system can more accurately control the rotation angle of the ceiling screen, thereby maximizing the safety of the members.

[0014] In the above technical solution, through explicit classification, the system can take corresponding warning and operation measures for different levels of dangerous states, thereby improving the processing efficiency; for different levels of dangerous states, the system can design different warning methods, for example, the first level can use regular information prompts, while the third level can use urgent sound and flashing red warning, prompting the members to immediately pay attention and react.

[0015] Further, the S200 includes:

[0016] It is judged whether the X-axis angular velocity is greater than a preset angular velocity threshold value, and if so, it is determined that the current vehicle is in a first driving risk level.

[0017] If the X-axis angular velocity is less than or equal to the preset angular velocity threshold value, it is judged whether there is an acceleration greater than a preset acceleration threshold value among the X-axis acceleration, Y-axis acceleration and Z-axis acceleration, and if so, it is determined that the current vehicle is in a second driving risk level.

[0018] If there is no acceleration greater than the preset acceleration threshold value, it is judged whether there is an acceleration greater than the preset acceleration threshold value and the number of occurrences is greater than or equal to a preset number within a preset time, and if so, it is determined that the current vehicle is in a third driving safety level; otherwise, it returns to S100.

[0023] Calculating a safe angle of the ceiling screen according to the initial angle, the relative position and a detection value, and controlling the ceiling screen to rotate to the safe angle, returning to S100.

[0024] In the above technical solution, the ceiling screen displays a special warning picture for the first driving danger level, which can intuitively convey the current abnormal state to the member and improve their alertness; by adjusting the ceiling screen to the safe angle according to the member information, it can be ensured that the member can avoid direct contact with the ceiling screen to the greatest extent when the impact occurs, thereby significantly reducing the risk of secondary injury caused by the ceiling screen to the member in the accident and enhancing the overall safety of the vehicle.

[0025] Further, when the current vehicle is in the second driving danger level, the S300 comprises:

[0026] Controlling the ceiling screen to broadcast a second warning picture corresponding to the second driving danger level, returning to S100.

[0029] Controlling the ceiling screen to broadcast a third warning picture corresponding to the third driving danger level.

[0030] Obtaining member information of a current vehicle member, so as to determine a relative position between the member and the ceiling screen according to the member information, and obtain an initial angle of the ceiling screen.

[0044] A danger warning and defense method, system, storage medium and vehicle of the present application are described in detail below with reference to specific embodiments and drawings.

[0045] Embodiment one:

[0046] Please refer to Figure 1 The present application provides a danger warning and defense method, and the current vehicle is provided with at least one gyroscope and at least one ceiling screen; the danger warning and defense method comprises the following steps:

[0047] S100: Real-time acquisition of detection values of the gyroscope of the current vehicle.

[0048] In some embodiments, the gyroscope is a six-axis gyroscope, which combines a three-axis angular velocity meter and a three-axis accelerometer, and the six axes are acceleration XYZ axes and angular velocity XYZ axes, which can sense both angle change and acceleration change.

[0049] Further, the detection values at least include acceleration and angular velocity; the acceleration at least includes X-axis acceleration, Y-axis acceleration and Z-axis acceleration; and the angular velocity at least includes X-axis angular velocity, Y-axis angular velocity and Z-axis angular velocity.

[0050] Among them, the forward direction of the current vehicle is the positive direction of the X-axis, the right side of the forward direction of the current vehicle is the positive direction of the Y-axis, and the upward direction of the jounce of the current vehicle is the positive direction of the Z-axis.

[0051] In some embodiments, the X-axis acceleration is the acceleration in the forward direction of the current vehicle, the Y-axis acceleration is the lateral acceleration perpendicular to the forward direction of the vehicle, and the Z-axis acceleration is the acceleration in the upward direction of the jounce of the vehicle; the X-axis angular velocity is the rotation speed of the vehicle around the X-axis, the Y-axis angular velocity is the rotation speed of the vehicle around the Y-axis, and the Z-axis angular velocity is the rotation speed of the vehicle around the Z-axis.

[0052] In the above technical solution, through detailed detection of the acceleration and angular velocity in the X, Y and Z directions, the motion state of the vehicle such as sharp turning, sudden braking and jounce can be comprehensively captured, so that the current driving danger level can be more accurately judged; based on the detailed acceleration and angular velocity data, the system can more accurately control the rotation angle of the ceiling screen, thereby maximizing the safety of the members.

[0053] S200: obtaining a driving danger level of the current vehicle according to the detection value.

[0054] Further, the driving danger level at least includes a first driving danger level, a second driving danger level and a third driving danger level.

[0055] In some embodiments, the first driving danger level represents that the vehicle is in a rollover or about to be in a rollover state, the second driving danger level represents that the vehicle may encounter an emergency situation, and the third driving danger level represents that the vehicle encounters an emergency situation, a bumpy road, severe driving, etc.

[0056] In other embodiments, those skilled in the art can also divide the driving danger level into more levels for more detailed threshold ranges.

[0057] In the above technical solution, through explicit level division, the system can take corresponding warning and operation measures for different levels of dangerous states, improving the processing efficiency; for different levels of dangerous states, the system can design different warning methods, for example, the first level can use regular information prompts, while the third level uses urgent sound and flashing red warning, prompting members to pay attention and react immediately.

[0058] Further, the S200 includes:

[0059] determining whether the X-axis angular velocity is greater than a preset angular velocity threshold, and if so, determining that the current vehicle is in a first driving danger level.

[0060] In some embodiments, a larger X-axis angular velocity may indicate that the vehicle has a more severe or unstable turn or sway, which may be in a rollover or about to be in a rollover state, posing a certain risk to the members in the vehicle.

[0061] Suppose a vehicle equipped with a danger warning and defense system is driving on a mountain road, the road is winding, and the driver operates improperly during a sharp turn, causing the vehicle to sway severely. At this time, the system detects through the gyroscope that the X-axis angular velocity of the vehicle exceeds the preset angular velocity threshold, and the system determines that the current vehicle is in a first driving danger level.

[0062] Wherein, the system detects that the X-axis angular velocity is 30 degrees / second, and the preset angular velocity threshold is 25 degrees / second; comparing the detection value and the preset angular velocity threshold, it is found that the X-axis angular velocity (30 degrees / second) is greater than the preset angular velocity threshold (25 degrees / second), and it is determined that the current vehicle is in a first driving danger level, and there is a risk of rollover.

[0063] If the X-axis angular velocity is less than or equal to the preset angular velocity threshold value, it is determined whether there is an acceleration greater than a preset acceleration threshold value among the X-axis acceleration, Y-axis acceleration and Z-axis acceleration. If there is, it is determined that the current vehicle is in the second driving danger level.

[0064] In some embodiments, if the X-axis angular velocity is less than or equal to the preset angular velocity threshold value, the next step is to determine whether there is an acceleration greater than the preset acceleration threshold value in any axis (X, Y, Z). If there is, it is determined that the current vehicle is in the second driving danger level. A larger acceleration in a certain axis may indicate that the vehicle is undergoing emergency braking, acceleration or being hit laterally, and the driver needs to be more alert to deal with potential emergencies.

[0065] Suppose a vehicle equipped with a danger warning and defense system is driving on an urban road, and the driver needs to avoid an emergency and suddenly brakes. At this time, the system detects through the sensor that the X-axis angular velocity is less than the preset angular velocity threshold value, but the X-axis acceleration (i.e. the acceleration of the vehicle in the forward direction) exceeds the preset acceleration threshold value, and the system determines that the current vehicle is in the second driving danger level.

[0066] In this example, the system detects that the X-axis angular velocity is 20 degrees per second, and the preset angular velocity threshold value is 25 degrees per second. Comparing the detected value and the preset threshold value, it is found that the X-axis angular velocity (20 degrees per second) is less than the preset angular velocity threshold value (25 degrees per second), and the next step is to determine.

[0067] Further, the detection values of the three-axis accelerometer are obtained, including the accelerations of the X-axis, Y-axis and Z-axis. The X-axis acceleration is detected as -6 m / s², the Y-axis acceleration as 0.5 m / s², and the Z-axis acceleration as 1.2 m / s². Comparing the detection values of each axis with the preset acceleration threshold value, it is assumed that the preset X-axis acceleration threshold value is -4 m / s², and the Y-axis and Z-axis acceleration threshold values are 2 m / s². The X-axis acceleration (-6 m / s²) is greater than the preset X-axis acceleration threshold value (-4 m / s²), and it is determined that the current vehicle is in the second driving danger level.

[0068] It should be noted that when comparing the acceleration, the absolute value is compared, and the positive and negative of the acceleration only represents the direction, not the size.

[0069] If there is no acceleration greater than the preset acceleration threshold value, it is determined whether there is an acceleration greater than the preset acceleration threshold value and the number of occurrences is greater than or equal to the preset number within a preset time. If there is, it is determined that the current vehicle is in the third driving safety level. Otherwise, it returns to S100.

[0070] In some embodiments, it is further determined whether there are multiple (greater than or equal to a preset number) accelerations greater than a preset acceleration threshold within a preset time, and if so, it is determined that the current vehicle is in the third driving safety level; multiple acceleration fluctuations within a short time may indicate that the vehicle is frequently jolted, decelerated or accelerated in complex road conditions, and there is a high safety risk.

[0071] Suppose a vehicle equipped with a danger warning and defense system is driving on a rural road, the road surface is rough, causing the vehicle to frequently jolt within a short time. The system detects through sensors that there are multiple accelerations greater than a preset acceleration threshold within a preset time, and determines that the current vehicle is in the third driving safety level.

[0072] Among them, suppose within a preset time such as 10 seconds, the first time: X-axis acceleration is -3 m / s², Y-axis acceleration is 0.8 m / s², and Z-axis acceleration is 1.5 m / s²; the second time: X-axis acceleration is -4 m / s², Y-axis acceleration is 1.2 m / s², and Z-axis acceleration is 1.8 m / s²; the third time: X-axis acceleration is -5 m / s², Y-axis acceleration is 0.6 m / s², and Z-axis acceleration is 2.0 m / s².

[0073] Suppose the preset X-axis acceleration threshold is -4 m / s², and the Y-axis and Z-axis acceleration thresholds are 2 m / s²; it is detected that the X-axis acceleration of the second and third times exceeds the preset acceleration threshold (-4 m / s²), a total of two times; the system records the number of times the acceleration exceeds the threshold within the preset time (for example, within 10 seconds), finds that the number of times the acceleration exceeds the preset acceleration threshold is 2, which is greater than the preset number (for example, set to 1), and the determination module determines that the current vehicle is in the third driving safety level, indicating a high driving risk.

[0074] If none of the above conditions are met, return to step S100 and continue to monitor the detection values of the vehicle gyroscope in real time.

[0075] In the above technical solution, through multi-dimensional and multi-level acceleration and angular velocity judgment, the system can more accurately identify different driving danger states, from slight shaking to emergency braking, and various levels of information are captured in detail.

[0076] And S300: controlling the ceiling screen to play a corresponding warning picture based on the driving danger level, or controlling the ceiling screen to play a corresponding warning picture based on the driving danger level and the detection value, and rotating to a corresponding angle.

[0077] Further, when the current vehicle is in the first driving danger level, the S300 includes:

[0078] The ceiling screen displays a first warning picture corresponding to the first driving danger level.

[0079] In some embodiments, it is determined that the current vehicle has a rollover risk, and the ceiling screen displays a corresponding first warning picture, such as "The vehicle is in a rollover risk, please be careful", and the warning picture can also be displayed with a corresponding rollover warning animation, and the display font color is set. Those skilled in the art can set the content of the warning picture according to the actual application requirements, and it is not limited to this.

[0080] In other embodiments, the display text in the ceiling screen can also be broadcast synchronously through the vehicle voice system.

[0081] Member information of the current vehicle members is obtained to determine the relative position of the members and the ceiling screen according to the member information, and an initial angle of the ceiling screen is obtained.

[0082] A safe angle of the ceiling screen is calculated according to the initial angle, the relative position and the detection value, and the ceiling screen is controlled to rotate to the safe angle, returning to S100.

[0083] In some embodiments, the system obtains member information of the current vehicle members, including at least the number and seat position of the members; assuming that there are 4 members in the vehicle, sitting in the driver's seat, the front passenger seat and the rear seats; the head orientation and the line of sight direction of each member are identified through the in-vehicle camera and the sensor, and then the relative position of each member and the ceiling screen is determined.

[0084] Further, the initial angle of the ceiling screen is obtained, assuming that the initial angle is 15 degrees horizontally downward; according to the initial angle, the relative position of the members and the detection value, the safe angle of the ceiling screen is calculated, assuming that the optimal safe angle is 10 degrees horizontally upward; the system controls the ceiling screen to rotate to the calculated safe angle (10 degrees horizontally upward), ensuring that all members can avoid collision with the ceiling screen.

[0085] After the broadcast and the angle adjustment are completed, the system returns to the initial state (S100) and continues to monitor the detection values of the vehicle in real time.

[0086] It should be noted that the head orientation and the line of sight direction of each member can be obtained through the in-vehicle camera and the line of sight tracking algorithm; for example, the line of sight of the member in the driver's seat is directed forward (0 degrees relative to the ceiling screen), the line of sight of the member in the front passenger seat is directed slightly to the right front (10 degrees relative to the ceiling screen), and the lines of sight of the two members in the rear seats are directed slightly to the left (-15 degrees relative to the ceiling screen) and to the right (5 degrees relative to the ceiling screen) respectively; then the average value of the relative positions is calculated and the safe margin angle for avoiding collision is set according to the detection value, and the safe angle is calculated according to the average value, the safe margin angle and the initial angle.

[0087] In the above technical solution, the control ceiling screen displays a dedicated warning picture for the first driving danger level, which can intuitively convey the current abnormal state to the member and improve their alertness; by adjusting the ceiling screen to a safe angle according to the member information, it is ensured that the member can maximize the avoidance of direct contact with the ceiling screen when a collision occurs, significantly reducing the risk of secondary injury to the member caused by the ceiling screen in an accident, and enhancing the overall safety of the vehicle.

[0088] Further, when the current vehicle is in the second driving danger level, the S300 includes:

[0089] The control ceiling screen broadcasts a second warning picture corresponding to the second driving danger level, and returns to S100.

[0090] In some embodiments, it is determined that the current vehicle may encounter an emergency situation, and the ceiling screen displays a corresponding second warning picture, such as displaying "the vehicle is in emergency braking, please fasten your seat belt", and the warning picture can also be displayed with a corresponding warning animation and a set display font color; those skilled in the art can set the content of the warning picture according to the actual application requirements, and it is not limited thereto.

[0091] In other embodiments, the display text in the ceiling screen can also be broadcasted synchronously through the vehicle voice system.

[0092] After the broadcast and angle adjustment are completed, the system returns to the initial state (S100) and continues to monitor the detection values of the vehicle in real time.

[0093] In the above technical solution, the second warning picture is specially designed for the driving situation of the second driving danger level, and the information is more targeted and direct.

[0094] Further, when the current vehicle is in the third driving danger level, the S300 includes:

[0095] The control ceiling screen broadcasts a third warning picture corresponding to the third driving danger level.

[0096] In some embodiments, it is determined that the current vehicle encounters an emergency situation, and the ceiling screen displays a corresponding third warning picture, such as "the vehicle is driving on complex road conditions, please maintain stable driving and fasten your seat belt", and the warning picture can also be displayed with a corresponding warning animation and a set display font color; those skilled in the art can set the content of the warning picture according to the actual application requirements, and it is not limited thereto.

[0097] In other embodiments, the display text in the ceiling screen can also be broadcasted synchronously through the vehicle voice system.

[0098] After the report and angle adjustment are completed, the system returns to the initial state (S100) and continues to monitor the detection values of the vehicle in real time.

[0099] Member information of the current vehicle member is acquired to determine the relative position of the member and the ceiling screen according to the member information, and the initial angle of the ceiling screen is acquired.

[0100] The safety angle of the ceiling screen is calculated according to the initial angle, the relative position, and the detection value, and the ceiling screen is controlled to rotate to the safety angle, and returns to S100.

[0101] In some embodiments, the above calculation method of the safety angle is the same as the corresponding calculation method of the safety angle in the first driving risk level, which is not described here.

[0102] In the above technical solution, the system flexibly displays different warning pictures for different driving risk levels, thereby enhancing the warning effect.

[0103] It should be noted that each of the above preset values can be set by a person skilled in the art according to actual application requirements, and is not limited to the above examples.
