[0041] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The vehicle's external airbag is an emergency self-protection device to solve the problem of danger during the driving process of the car. In addition to passive activation, the vehicle's external airbag in the embodiment of the present application has intelligent prediction and manual active activation modes. Compared with the traditional airbag activated after an accident, the embodiment of the present application is that the traditional airbag mainly directly protects the safety of the driver and passengers in the car, and the external airbag indirectly protects the driver and passengers in the car and the accident-related personnel, which can better avoid or reduce the accident hazard coefficient. Specifically, for the protection object, the traditional vehicle-mounted airbag directly protects people; the external airbag indirectly protects people and directly protects vehicles, and the advantage is that it can avoid secondary injuries after an accident. For the protection motive, the traditional vehicle-mounted airbag is passively controlled; the external airbag is actively or passively intelligently controlled, which can actively reduce the risk level of accidents. For the protection cost, the traditional vehicle-mounted airbag ejects all protective air cushions; the external airbag ejects air cushions according to levels and scenes, which can reduce costs. For protection scenarios, traditional on-board airbags provide passive protection against impact; external airbags provide active protection against water and impact, which can buy time for escape after water wading.

[0043] See also Figure 1 , Figure 1 The flowchart of the vehicle safety control method of the present invention is applied to a vehicle, and the vehicle is provided with an external airbag. The external airbag of the embodiment of the present application can take emergency self-protection measures against the dangers encountered during the driving of the vehicle, avoid the occurrence of serious accidents, and reduce losses.

[0044] like Figure 1 As shown, the vehicle safety control method according to the embodiment of the present invention includes:

[0045] Step S100: Determine the relative movement information of the vehicle relative to the obstacle, and determine the control result of the external airbag according to the relative movement information.

[0046] Specifically, the external airbag of the embodiment of the present application can be set in an intelligent mode, which monitors the vehicle's surrounding environment in real time and predicts whether to activate the external airbag based on the surrounding environment.

[0047] like Figure 2 As shown, a communication module, a power supply module, a drive module and a manual event module are provided, each module is connected to a processor, and an external airbag is connected to the processor. The processor is used to coordinate the work of various components of the intelligent airbag device. The manual event module is used to trigger an external airbag event, and the airbag is opened when the button is pressed; the drive module is used to drive the airbag to open for safety protection; the power supply module is used to supply power to the intelligent airbag device; and the communication module is used to communicate with the vehicle system.

[0048] Inertial sensors and radars can be installed on the vehicle to collect data, and then analyze dangerous events in the external detection environment in real time through fusion algorithms.

[0049] Specifically, the data collected by the radar sensor is mainly used to calculate the real-time distance between the vehicle and the obstacle and the size of the obstacle, and can also determine the intrusion direction of the obstacle. The inertial sensor is a sensor that integrates a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer. These sensors obtain the motion state of an object in space, such as position, speed, acceleration, angle, etc., by measuring information such as the object's acceleration, angular velocity, and magnetic field strength. The accelerometer is used to measure the acceleration of an object due to the earth's gravity or the movement of the object, that is, the rate of change of the object's speed per unit time; the gyroscope is used to measure the angular velocity of the object, that is, the rotation speed of the object per unit time. By integrating the angular velocity data output by the gyroscope, the rotation angle of the object relative to the initial position can be obtained.

[0050] Both radar and inertial sensors collect real-time data, perform real-time calculations, and combine algorithms to output vehicle attitude in real time. For example, calculations are performed based on the Mahony complementary filter algorithm, the Kalman filter algorithm, or the EKF attitude fusion algorithm.

[0051] The complementary filtering algorithm based on Mahony is characterized by using the complementary characteristics of the output of the gyroscope, accelerometer and magnetometer for fusion and solution. Usually, the output of the gyroscope has a high-frequency characteristic, that is, it is more sensitive when the carrier moves at high speed, while the accelerometer and magnetometer are just the opposite, and the accuracy is higher when the carrier movement changes less. The complementary filtering algorithm uses the PID feedback controller to feedback the error amount to compensate for the correction of the gyroscope error. Specifically, according to the data of the accelerometer and magnetometer, after converting to the geographic coordinate system, the cross multiplication error is calculated with the corresponding reference gravity vector and geomagnetic vector. This error is used to correct the output of the gyroscope, and then the quaternion is updated with the gyroscope data, and then converted to the Euler angle. That is, the accelerometer output is used to correct the roll angle and pitch angle errors of the gyroscope, and the magnetometer output is used to correct the heading angle error of the gyroscope, thereby giving a more stable and slower divergence attitude fusion result. The complementary filtering algorithm can make up for the defects of the accelerometer and gyroscope measuring the tilt angle value separately. A weight coefficient is multiplied in front of the accelerometer value and the gyroscope value respectively, that is, the two sensors contribute a part respectively, and a weighted average is performed. The formula is as follows:

[0052] angle=k*angle_m+(1-k)*(angle+gyro_m*dt);

[0053] Among them, angle is the angle value after fusion, angle_m is the angle measured by the accelerometer, angle+gyro_m*dt is the angle obtained by gyroscope integration, dt is the sampling period, and k is the complementary filter weight coefficient. If you want the accelerometer measurement result to have a greater impact on the final result, increase k; otherwise, reduce it, that is, make the gyroscope measurement value have a greater impact on the final result. The complementary filter algorithm can better derive the vehicle posture.

[0054] In the first embodiment of the present application, step S100 specifically includes:

[0055] Step S110a, using a preset inertial sensor to collect the motion posture of the vehicle, and using a preset radar to collect the obstacle movement speed of the obstacle and the real-time distance between the vehicle and the obstacle;

[0056] Step S120a, determining a relative moving speed according to the motion posture and the moving speed of the obstacle, and using the relative moving speed and the real-time distance between the vehicle and the obstacle as relative movement information of the vehicle relative to the obstacle;

[0057] Step S130a: If the relative moving speed is greater than a preset speed threshold and the real-time distance between the vehicle and the obstacle is gradually reduced, it is determined that the external airbag control result is to pop out the external airbag.

[0058] Specifically, the relative movement information of this embodiment includes: the relative movement speed and the real-time distance between the vehicle and the obstacle. When the relative movement speed is greater than the preset speed threshold, it is determined whether the real-time distance between the vehicle and the obstacle is gradually decreasing. If so, it proves that there is a probability of collision, and the external airbag is prepared to pop out.

[0059] It is understandable that if the two conditions that the relative moving speed is greater than the preset speed threshold and the real-time distance between the vehicle and the obstacle is gradually reduced are not met at the same time, that is, under the following conditions, the control result of the external airbag is that the external airbag will not be deployed:

[0060] First, the relative moving speed is less than or equal to the preset speed threshold, and the real-time distance between the vehicle and the obstacle is gradually reduced;

[0061] Second, the relative moving speed is greater than the preset speed threshold, and the real-time distance between the vehicle and the obstacle does not gradually decrease;

[0062] Third, the relative moving speed is less than or equal to the preset speed threshold, and the real-time distance between the vehicle and the obstacle does not gradually decrease.

[0063] The embodiment of the present application determines whether there is a probability of collision between the current vehicle and the obstacle by judging the relative moving speed and the preset speed threshold and whether the real-time distance between the vehicle and the obstacle is gradually reduced. If so, the airbag outside the vehicle is prepared to pop out, the danger is predicted, and active opening is achieved, which can avoid or reduce the level of injury, increase the contact area, improve the stability of the vehicle, and prevent rollover. It not only avoids secondary injuries, but also effectively reduces the impact intensity of the initial collision.

[0064] In the second embodiment of the present application, the step S100 specifically includes:

[0065] Step S110b, using a preset inertial sensor to collect the motion posture of the vehicle, and using a preset radar to collect the obstacle movement speed of the obstacle, the real-time distance between the vehicle and the obstacle, and the obstacle area;

[0066] Step S120b, determining a relative moving speed according to the motion posture and the moving speed of the obstacle, and using the relative moving speed, the real-time distance between the vehicle and the obstacle, and the area of ​​the obstacle as relative movement information of the vehicle relative to the obstacle;

[0067] Step S130b: if the relative moving speed is greater than a preset speed threshold, the real-time distance between the vehicle and the obstacle is gradually reduced, and the area of ​​the obstacle is greater than a preset area threshold, it is determined that the external airbag control result is to pop out the external airbag.

[0068] Specifically, the relative movement information of this embodiment includes: relative movement speed, real-time distance between the vehicle and the obstacle, and obstacle area. When the relative movement speed is greater than a preset speed threshold, and the real-time distance between the vehicle and the obstacle gradually decreases, it is determined whether the obstacle area is greater than the preset area threshold. If so, it proves that the obstacle is large and there is a probability of collision, which will cause a more serious collision, and then the external airbag is prepared to pop out.

[0069] It can be understood that if the three conditions of the relative moving speed being greater than the preset speed threshold, the real-time distance between the vehicle and the obstacle gradually decreasing, and the area of ​​the obstacle being greater than the preset area threshold are not met at the same time, the control result of the external airbag is that the external airbag will not pop out.

[0070] For example, scenario one is that the vehicle is stationary and the obstacle is moving. The obstacle's current moving speed is greater than 30km / h, the moving distance within 2 seconds is greater than 30m, the moving direction is from far to near, and the obstacle area is greater than 1 square meter. Scenario two is that the vehicle is moving and the obstacle is also moving. The relative moving speed is greater than 30km / h, the relative moving distance within 2 seconds is greater than 30m, the moving direction is from far to near, and the obstacle area is greater than 1 square meter. Scenario three is based on scenarios one and two, when the vehicle posture changes or the linked airbags are detonated in time at the front (A), rear (B), left (L), and right (R), such as when the vehicle rolls over.

[0071] The embodiment of the present application determines whether there is a probability of collision between the current vehicle and the obstacle and whether the obstacle will cause a serious impact on the vehicle by judging the relative moving speed and the preset speed threshold, whether the real-time distance between the vehicle and the obstacle is gradually decreasing, and whether the area of ​​the obstacle is greater than the preset area threshold. If there is a probability of collision and the obstacle will cause a serious impact on the vehicle, the external airbag is prepared to pop out, the danger is predicted, and active opening is achieved, which can avoid or reduce the level of injury, increase the contact area, improve the stability of the vehicle, and prevent rollover. It not only avoids secondary injuries, but also effectively reduces the impact intensity of the initial collision.

[0072] In an embodiment of the present application, there are four external airbags, including: a first external airbag arranged at the front end of the vehicle's exterior, a second external airbag arranged at the rear end of the vehicle's exterior, a third external airbag arranged at the left side of the vehicle's exterior, and a fourth external airbag arranged at the right side of the vehicle's exterior.

[0073] Specifically, Figure 3 and Figure 4 As shown, the first external airbag A can be stored above the license plate, the second external airbag B can be stored in the bumper, the third external airbag L can be stored above the left wheel eyebrow near the door, and the fourth external airbag R can be stored above the right wheel eyebrow near the door. The first external airbag A can cover the front end of the vehicle after it is popped out, the second external airbag B can cover the rear end of the vehicle after it is popped out, the third external airbag L can cover the left side of the vehicle after it is popped out, and the fourth external airbag R can cover the right side of the vehicle after it is popped out.

[0074] In addition, corresponding radar and inertial sensors may be provided for each exterior airbag.

[0075] The embodiment of the present application arranges external airbags in four directions, and realizes the activation of airbags in different levels and scenarios. Because some scenarios do not require all airbags to be popped out, the airbags are detonated one by one according to the on-site environment, reducing the cost of accidents.

[0076] like Figure 1 As shown, the vehicle safety control method described in this embodiment also includes:

[0077] Step S200: If the external airbag control result is the deployment of the external airbag, a preset airbag deployment information table is searched to obtain a target distance corresponding to the relative movement information.

[0078] In the embodiment of the present application, the step S200 specifically includes:

[0079] Step S210: If the external airbag control result is that the external airbag is deployed, the position of the obstacle relative to the vehicle is obtained, and the position is collected by using a pre-set radar;

[0080] Step S220, determining a target external airbag to be ejected among the external airbags according to the position of the obstacle relative to the vehicle, and searching a preset airbag ejection information table, wherein the airbag ejection information table includes a correspondence between a relative moving speed range and a target distance;

[0081] Step S230: determine a target relative moving speed range within which the relative moving speed is located, and use a target distance corresponding to the target relative moving speed range as a target distance.

[0082] Specifically, different types of airbags may have different detonation times, so the corresponding airbag pop-up information table can be set according to the detonation time of the airbag. For example, the detonation time of the airbag is 0.03 seconds, that is, 30 milliseconds. The braking distance of the car is proportional to the speed. When the speed is 30km / h, the braking distance is 9 meters, when the speed is 50km / h, the braking distance is 12 meters; and when the speed reaches 100km / h, the braking distance increases to 48 meters. This shows that the faster the speed, the longer the required braking distance. The external airbag does not consider the situation where the speed is less than 30km / h. Even at low speed, the risk factor of frontal collision is not high. The detonation distance (S) is equal to the relative moving speed (V) multiplied by the time (T), that is, S = V*T. As shown in Table 1.

[0083] Relative moving speed Detonation time Detonation distance v<30km / h invalid invalid 30km / h≤v<40km / h 30ms 0.3m 40km / h≤v<50km / h 30ms 0.4m 50km / h≤v<60km / h 30ms 0.5m 60km / h≤v<70km / h 30ms 0.6m 70km / h≤v<80km / h 30ms 0.7m 80km / h≤v<90km / h 30ms 0.8m 90km / h≤v<100km / h 30ms 0.9m 100km / h≤v<110km / h 30ms 1.0m 110km / h≤v<120km / h 30ms 1.1m 120km / h≤v<130km / h 30ms 1.2m 130km / h≤v<140km / h 30ms 1.3m … … …

[0084] Table 1

[0085] The embodiment of the present application pre-sets the corresponding relationship between the relative moving speed range and the target distance, and then determines the timing of deploying the airbag. It will not be deployed too early or too late. Popping up too early may lead to misjudgment, and popping up too late may lead to unavoidable collision, thereby improving the accuracy of airbag deployment.

[0086] like Figure 1As shown, the vehicle safety control method described in this embodiment also includes:

[0087] Step S300: When the current distance between the vehicle and the obstacle is less than or equal to the target distance, the external airbag is deployed.

[0088] Specifically, when the airbag deployment timing is reached, the external airbag is deployed to avoid collision in time. It is understandable that if the current distance between the vehicle and the obstacle is greater than the target distance, the deployment timing has not been reached. If the distance between the vehicle and the obstacle never reaches the target distance, it means that the vehicle will not collide with the obstacle.

[0089] In the embodiment of the present application, the step S300 specifically includes: when the current distance between the vehicle and the obstacle is less than or equal to the target distance, popping out a target external airbag to be popped out among the external airbags.

[0090] Specifically, the front (A), rear (B), left (L), and right (R) airbags work independently, and each airbag protects the safety of the corresponding direction. They are both independent and can be linked to each other. For example, when an accident occurs in the front (A), the rear (B) and left (L) airbags will be linked according to the on-site situation. When an accident occurs in the rear (B), the right (R) and left (L) airbags will be linked, etc. Therefore, the embodiment of the present application can set a coordinated airbag mode, that is, a certain airbag can be ejected alone, or more than two airbags can be ejected in coordination.

[0091] The embodiment of the present application arranges external airbags in four directions, realizes the individual activation of airbags according to levels and scenarios, and reduces accident costs.

[0092] In one embodiment of the present application, the vehicle safety control method further includes: when a manual trigger button pressing command is received, popping out the external vehicle airbag; or, when the vehicle encounters a collision, sensing the impact event based on a pre-set collision sensor, and popping out the external vehicle airbag.

[0093] That is to say, the embodiments of the present application can also be set to a manual mode and a passive mode. The manual mode means that in case of danger during the driving of the vehicle, the external airbag is activated by manually pressing a button. The button is set in a position where the driver can quickly operate it, for example, it is set on the steering wheel or the center console, and the design filters out mispresses and misoperations. For example, the external airbag activation button can be sunken 3 cm into the plane structure, and a certain force is required to press it to start, to prevent children from pressing it or triggering it by mistake. The passive mode is similar to the activation method of the traditional vehicle-mounted airbag. In addition, the four external airbags in the manual mode are controlled by one button. This is because in an emergency, it is difficult for the driver to make a choice between the front, back, left and right.

[0094] In one embodiment, if Figure 5 As shown, based on the above vehicle safety control method, the present invention also provides a vehicle safety control device, which is applied to a vehicle, wherein the vehicle is provided with an external airbag, and the device comprises:

[0095] A determination module 100, configured to determine relative movement information of the vehicle relative to the obstacle, and determine an external airbag control result according to the relative movement information;

[0096] A search module 200, configured to search a preset airbag pop-up information table to obtain a target distance corresponding to the relative movement information if the external airbag control result is the external airbag pop-up;

[0097] The pop-up module 300 is used to pop out the external airbag when the current distance between the vehicle and the obstacle is less than or equal to the target distance.

[0098] Figure 6 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application. The vehicle is provided with an external airbag, and the vehicle may include:

[0105] If the memory 501, the processor 502 and the communication interface 503 are implemented independently, the communication interface 503, the memory 501 and the processor 502 can be connected to each other through a bus and communicate with each other. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component (PCI) bus or an Extended Industry Standard Architecture (EISA) bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one line is used in the figure, but it does not mean that there is only one bus or one type of bus.

[0106] Optionally, in a specific implementation, if the memory 501, the processor 502 and the communication interface 503 are integrated on a chip, the memory 501, the processor 502 and the communication interface 503 can communicate with each other through an internal interface.

[0107] The processor 502 may be a central processing unit (CPU), or an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application.

[0108] This embodiment also provides a computer-readable storage medium on which a computer program is stored. When the program is executed by a processor, the above vehicle safety control method is implemented.
