[0049] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0050] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described in the following. Of course, they are only examples and are not intended to limit the present application. In addition, reference numerals and / or letters can be repeated in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate a relationship between the various embodiments and / or arrangements being discussed.

[0051] The present application provides a control method, device and equipment of a vehicle safety device, and a storage medium. The present application can automatically adjust various safety devices of a vehicle after a collision of the vehicle, thereby improving the safety of a user.

[0052] Referring to Figure 1 , Figure 1 A control method flow chart of a vehicle safety device is provided in the embodiments of the present application, and the method specifically includes the following steps:

[0053] S101, acquiring collision signals collected by each collision sensor; wherein each collision sensor is pre-installed at different detection positions of the vehicle;

[0054] In the related art, most of the automobile safety systems are independently operated, and lack a unified intelligent control system to coordinate the work of various safety devices. In the present application, an intelligent control system is provided in the vehicle, and the control method described in the present application is executed through the intelligent control system, that is, the intelligent control system receives the collision signals collected by each collision sensor after a collision of the vehicle, and controls the corresponding target safety device to perform the corresponding safety operation according to the severity of the collision. In order to ensure that the intelligent control system is not easily damaged after a collision of the vehicle, the intelligent control system can be installed in the central passage of the vehicle, that is, the position between the main driver seat and the co-driver seat. There will be a special protection structure inside the central passage, and the control system is installed in these protection structures to further improve its anti-collision capability. The number of collision sensors is not specifically limited, and can be set according to actual needs. In the present embodiment, four collision sensors can be pre-installed on the vehicle, which are installed at the front, rear, left side and right side of the vehicle.

[0055] Referring to Figure 2 , a schematic diagram of an intelligent escape system based on seat and door for a vehicle is provided in the present application, which includes a vehicle 1, a first collision sensor 11, a second collision sensor 12, a third collision sensor 13, a fourth collision sensor 14, and an intelligent control system 15. Among them, the first collision sensor 11 is installed inside the front bumper of the vehicle, which can detect the impact force at the first time when the front collision occurs, and is crucial for judging the collision intensity of the front part of the vehicle. The second collision sensor 12 is installed inside the rear bumper of the vehicle, and the rear collision sensor is mainly used to detect the collision from the rear, such as a rear-end accident. The third collision sensor 13 is installed on the left front door side of the vehicle body, and the fourth collision sensor 14 is installed on the right front door side of the vehicle body. The collision sensors on both sides of the vehicle body can detect the situation of side collision.

[0056] S102, determining the collision severity of the vehicle by using the collision signal;

[0057] In the present application, if the vehicle has a collision, the collision sensors will send a collision signal to the intelligent control system at this time, which includes the collision intensity, the collision sensor position information, the collision duration, and the collision occurrence time. Among them, the collision intensity is one of the most important data in the collision signal, which represents the impact force generated during the collision. The intelligent control system determines the severity of the collision according to the size of the collision intensity, so as to determine whether to start each safety device in the escape system. The greater the collision intensity, the more serious the collision severity, and the two are in a direct proportional relationship. For example: if the collision intensity is small, it means that the collision severity is not serious, and in this case, only an alarm needs to be sent to remind the people inside the vehicle; if the collision intensity is large, it means that the collision severity is serious, and in this case, the safety airbag needs to be ejected immediately, and the seat adjustment and door opening escape functions need to be started.

[0058] In addition, since each collision sensor has its specific installation position, the collision signal sent by the collision sensor also has the installation position of the collision sensor itself. The intelligent control system can accurately determine the specific part of the vehicle where the collision occurs according to the installation position of each collision sensor and the collision intensity. The collision duration represents the length of time of the collision. Some collisions may be instantaneous impact, while some collisions may last for a period of time, such as vehicle sliding or rolling after collision, etc. The collision occurrence time is used to record the time point of the collision, which is accurate to the millisecond level. This data is helpful for analyzing the accident process and determining the response time of the escape system.

[0059] S103, determining the first target safety device to be triggered according to the collision severity; wherein the first target safety device is at least one of an alarm device, a safety airbag device, a seat adjustment device, and a door opening device.

[0060] In the present application, the first target safety device to be triggered can be determined according to the severity of the collision. The more serious the severity of the collision, the more safety devices need to be triggered. That is, in the case of a more serious collision, more safety devices need to be triggered to ensure user safety. For example, if the severity of the collision is not serious, the first target safety device to be triggered is only an alarm device; if the severity of the collision is serious, the first target safety device to be triggered includes an alarm device, an airbag device, a seat adjustment device, and a door opening device.

[0061] The alarm device is a device that reminds the user to pay attention to the collision situation through sound, light, or display screen prompts, etc., and checks whether the user is injured. The airbag device is used to pop up the airbag, and the pop-up of the airbag can provide additional protection for the passenger and reduce the risk of injury to the head, chest, and other key parts. The seat adjustment device is used to move the seat of the user inside the vehicle, and by adjusting the seat, more escape space can be provided for the passenger. The door opening device is used to control the opening of the door to help the passenger leave the vehicle as soon as possible.

[0062] S104, controlling the first target safety device to perform a corresponding safety operation.

[0063] After the present application determines the first target safety device to be triggered according to the severity of the collision, the first target safety device can be controlled to perform a corresponding safety operation. For example, if the first target safety device is an alarm device, the alarm device is controlled to issue a prompt message, and the alarm information can also be sent to predetermined contacts, such as the driver's relatives, insurance personnel, etc. If the first target safety device is a seat adjustment device, control information is sent to the seat adjustment device to control the seat adjustment device to adjust the seat position in time. If the first target safety device is a door opening device, control information is sent to the door opening device to control the opening of the door.

[0064] Since the circuit communication mode is easy to be cut off after the vehicle collision, in the present application, in order to ensure that the intelligent control system and the collision sensor, the safety device can effectively transmit data, the following two communication modes can be used: the first: using wireless Bluetooth communication, Bluetooth technology has the characteristics of low power consumption and short distance transmission, which can establish a stable wireless connection in the vehicle. After the collision occurs, even if part of the circuit is cut off, the Bluetooth connection is still possible to remain stable. For example: the intelligent control system can communicate with the seat adjustment device and the door opening device through Bluetooth, and realize the functions of seat adjustment and door opening. The second: using wired optical fiber communication, optical fiber communication has the characteristics of high speed, high bandwidth and strong anti-interference ability, which can be used as a reliable wired backup communication mode. Lay optical cable in the vehicle, connect the intelligent control system with the key components. After the collision occurs, even if part of the circuit is cut off, the optical fiber communication is still possible to remain stable, ensuring the reliability of data transmission. The present application can use the above-mentioned one way to communicate, or can use the above-mentioned two ways to communicate at the same time, so as to maximize the reliability of data transmission after the collision occurs.

[0065] As can be seen from the above, the present application can detect the collision signal through the collision sensor, and take different safety measures according to the severity of the collision, such as issuing an alarm, popping up a safety airbag, starting a seat adjustment and a door opening function, etc. to provide all-round safety protection for the people in the vehicle. Moreover, the present application uses wireless Bluetooth communication and wired optical fiber communication, which can ensure that after the collision occurs, the safety devices can effectively control the safety operation and realize reliable data transmission.

[0066] In another embodiment of the present application, if the first target safety device is a seat adjustment device, the process of controlling the first target safety device to perform the corresponding safety operation includes the following contents: updating the internal space model of the vehicle according to the collision signal; determining the space demand coefficient by using the body shape information and the posture information of the people in the vehicle; calculating the seat moving distance according to the internal space model and the space demand coefficient; sending the first control information to the seat adjustment device by using the seat moving distance, so that the seat adjustment device controls the seat to move to the specified position.

[0067] If the vehicle is in a collision, the car head and the body left and right sides suffer severe collision, at this time due to the deformation of the car structure and the airbag pops out, the front row of the vehicle is easy to be stuck in the car, in the related technology, after the collision occurs, the seat position cannot be automatically adjusted and the door cannot be opened according to the specific situation of the collision, which needs to be manually operated by the vehicle personnel, which may delay the valuable escape time in an emergency. Therefore, in this application, if the collision severity of the vehicle is determined according to the collision signal, especially after any one of the first collision sensor 11, the third collision sensor 13 and the fourth collision sensor 14 detects a severe collision, the intelligent control system sends a first control signal to the seat adjusting device, the first control signal is used to control the seat adjusting device to adjust the seat to a specified position according to the seat moving distance, so as to provide more escape space for the passengers. The deformation degree of the vehicle after the collision must be considered when adjusting the seat position, and the vehicle deformation data is obtained according to the vehicle body deformation sensor. The body size of the vehicle personnel is very different, and more space is needed for the personnel with larger body size to avoid being stuck, and the posture of the vehicle personnel at the moment of collision is also very important, and the body size and posture information of the passengers are obtained according to the vehicle camera.

[0068] Referring to Figure 3 , a seat moving distance implementation process schematic diagram provided in the application; by Figure 3 It can be seen that the intelligent control system needs to determine the distance that the seat needs to move by establishing a space model, determining the safety space requirement and comprehensively calculating the distance. The space model is a three-dimensional space model of the vehicle interior pre-stored in the intelligent control system, which contains the position and size information of each component in the vehicle, such as seats, center consoles, doors, etc. The model is established and stored in the memory of the control system during the design stage of the vehicle. The application can update the vehicle interior space model in real time according to the collision signal (collision strength, collision position and collision direction) and the data collected by the vehicle body deformation sensor. For example, when the head part is detected to be deformed, the space size of the head part in the model is correspondingly reduced, reflecting the actual change of the vehicle interior space, if the change of the vehicle interior space affects the adjustment of the seat, then when determining the seat moving distance, the seat moving distance will be adjusted according to the change of the vehicle interior space.

[0069] The application can determine the safety space requirement according to the body shape and posture information of the person in the vehicle, and then determine the space requirement coefficient according to the safety space requirement. The intelligent control system classifies the body shape of the person into different categories: slim, medium, and obese. Different space requirement coefficients k1 are set for different body shape categories. For a person with a slim body shape, the coefficient is set to 1.0, indicating that no additional space adjustment is required. For a person with a medium body shape, the coefficient is set to 1.3, indicating that an additional 30% of space is required. For a person with an obese body shape, the coefficient is set to 1.6, indicating that an additional 60% of space is required. The posture of the person is classified into different categories: normal sitting posture, forward leaning, and backward leaning. Corresponding adjustment coefficients k2 are set for different postures. The coefficient for normal sitting posture is set to 1.0. The coefficient for forward leaning posture is set to 1.2, indicating that an additional 20% of space is required. The coefficient for backward leaning posture is set to 0.9, indicating that the required space can be reduced by 10%. The intelligent control system determines the distance that the seat can move as S0 based on the initial position of the seat. The distance that the seat can move can be adjusted according to the actual change in the space in the vehicle reflected by the space model. For example, after the vehicle is hit, the space in the vehicle becomes smaller, and at this time, the distance that the seat can move will be less than S0.

[0070] Through the above process, the first space requirement coefficient k1 can be determined based on the body shape information, and the second space requirement coefficient k2 can be determined based on the posture information. That is, the safety space requirement based on the body shape is k1*S0, and the safety space requirement based on the posture is k2*S0. According to the safety space requirements based on the body shape and the posture, the total safety space requirement is calculated as k1*k2*S0. Therefore, in the application, the distance that the seat needs to move is D=(k1*k2-1)*S0. The seat adjustment device is equipped with a position sensor, which feeds back the position information of the seat to the intelligent control system. The control system determines whether the seat has moved to the specified position based on the feedback information. If the seat has not reached the specified position, the control system will continue to send instructions to the motor until the seat reaches the specified position.

[0071] In some embodiments of the application, after sending the first control information to the seat adjustment device using the seat movement distance, the seat is controlled to move to the specified position by the seat hydraulic auxiliary device if it is detected that the seat has not moved to the specified position.

[0072] Wherein, the application sends the first control information to the seat adjustment device, and sets a detection time. If the seat is not found to be moved to the specified position after the detection time is exceeded, it can be determined that the seat adjustment device is damaged by collision and cannot work normally. In the application, a seat hydraulic auxiliary device is also provided in the vehicle interior, which can control the seat to move to the specified position. For example, a manual hydraulic pump is installed in the seat hydraulic auxiliary device. When the motor of the seat adjustment device is damaged, the person in the vehicle can operate the manual hydraulic pump to provide hydraulic power to push the seat backward. The manual hydraulic pump generates hydraulic pressure by repeated pressing, and is connected to the hydraulic cylinder of the seat. The person in the vehicle pushes the manual hydraulic pump to inject hydraulic oil into the cylinder to push the seat backward.

[0073] As can be seen from the above, the application calculates the seat moving distance according to the internal space model of the vehicle and the size and posture of the person inside the vehicle, and accurately adjusts the seat position through the seat adjustment device to provide more escape space for passengers and improve safety. In order to avoid the seat adjustment device from failing to adjust the seat position in time in the event of a collision, the seat position can be adjusted through the seat hydraulic auxiliary device after the seat adjustment device fails to adjust, providing double protection for seat adjustment and improving safety.

[0074] In order to help passengers leave the vehicle as soon as possible after a collision and improve user safety, in another embodiment of the application, if the first target safety device is a door opening device, the first target safety device is controlled to perform corresponding safety operations, specifically including the following contents: activating the backup power supply to supply power to the electromagnetic door opening device; sending second control information to the electromagnetic door opening device to open the corresponding door through the electromagnetic door opening device.

[0075] If the vehicle suffers a severe collision, the vehicle occupants should immediately leave the vehicle to prevent the vehicle from catching fire and causing harm to themselves, but the existing vehicle door opening method mainly relies on electronic locks and mechanical locks. After the collision, the electronic system may be damaged, and the opening method of the mechanical lock may be affected by the deformation of the vehicle, making it difficult to open the door and bringing great difficulty to the escape of the vehicle occupants. Therefore, in the present application, the intelligent control system determines that the collision severity of the vehicle is relatively serious according to the collision signal, and at this time the intelligent control system sends a second control signal to the electromagnetic door opening device, which is used to control the electromagnetic door opening device to open the corresponding door, such as: only opening the doors of the main driver and the co-driver, or opening all the doors. In the present application, the electromagnetic door opening device is provided with an independent backup power supply to ensure that it can still work normally in the case that the main power supply of the vehicle is damaged. Therefore, when opening the door, the backup power supply needs to be activated to provide power for the electromagnetic door opening device. The electromagnetic door opening device generates a strong magnetic force to release the locking state of the door: the electromagnetic coil in the electromagnetic door opening device generates a magnetic field after being energized, attracting or repelling the metal parts in the door lock mechanism, so that the lock tongue is separated from the lock hole. The metal parts installed on the door cooperate with the electromagnetic door opening device, and when the electromagnetic force acts, these metal parts are subjected to a pushing force, thereby driving the door to open outward.

[0076] In some embodiments of the present application, after the intelligent control system sends a second control signal to the electromagnetic door opening device, the present application further includes: if it is detected that the door is in a closed state, the door is opened by the mechanical door opening device. Wherein, after the intelligent control system sends a second control signal to the electromagnetic door opening device, a detection time can be set, if the detection time is exceeded and it is found that the door is still in a closed state, it can be determined that the electromagnetic door opening device is damaged by the collision and cannot work normally. In the present application, the vehicle is also provided with a mechanical door opening device, which can open the door through the mechanical door opening device, providing double guarantee for the opening of the door and enhancing the reliability of the automobile escape system. For example: an emergency unlocking pull rod that can be manually pulled is arranged at a specific position of the door trim, when the electromagnetic device fails, the vehicle occupants can quickly find this pull rod and pull it hard. The pull rod is connected to the door lock mechanism through a series of mechanical links, and pulling the pull rod will directly unlock the door lock.

[0077] As can be seen from the above, after the collision occurs, the seat can be automatically moved to a suitable position according to the collision situation, effectively avoiding the front row personnel from being stuck, and creating favorable conditions for escape; and the application can also be combined with the electromagnetic door opening device and the mechanical door opening device, so that the electromagnetic door opening device can quickly respond to open the door under normal circumstances, and when the electromagnetic door opening device fails, the mechanical door opening device can ensure that the door is smoothly opened. The intelligent control system of the application can automatically start the corresponding safety device according to the severity of the collision, realize functions such as alarm, airbag pop-up, seat adjustment and door opening, realize the unified and coordinated work of each safety device, the design of the scheme is reasonable and easy to realize, can be applied to various types of cars, and has a wide application prospect.

[0078] Referring to Figure 4 , Figure 4 Another control method flow diagram of a vehicle safety device provided by the embodiment of the application is provided, and the method specifically includes the following steps:

[0079] S201, acquiring the collision signals collected by each collision sensor; wherein each collision sensor is pre-set at different detection positions of the vehicle;

[0080] S202, determining the severity of the collision of the vehicle by using the collision signals;

[0081] S203, determining the first target safety device to be triggered according to the severity of the collision; wherein the first target safety device is at least one of the alarm device, the airbag device, the seat adjustment device and the door opening device;

[0082] S204, controlling the first target safety device to perform the corresponding safety operation.

[0083] S205, receiving a voice control instruction;

[0084] S206, determining the second safety device corresponding to the voice control instruction; wherein the second target safety device is at least one of the alarm device, the airbag device, the seat adjustment device and the door opening device;

[0085] S207, controlling the second safety device to perform the corresponding safety operation.

[0086] In normal circumstances, after the vehicle is in collision, the intelligent control system will automatically control the first target safety device to perform corresponding safety operation according to the collision severity, if the safety device controlled by the system is not the safety device that the user wants to control, or the system control fails, at this time the user can also control the corresponding second target safety device to perform corresponding safety operation through voice control. Among them, the intelligent control system integrates a high-performance voice recognition module, which can recognize the voice control instruction of the person in the vehicle, determine the second safety device that the user wants to control according to the voice control instruction, and control the second safety device to perform corresponding safety operation.

[0087] For example: after the collision occurs, the collision severity is moderate collision mode, at this time the intelligent control system does not control the seat adjustment device to adjust the seat position, and does not control the door opening device to open the door, at this time the user can control the seat adjustment device to adjust the seat position and control the door opening device to open the door by issuing a voice control instruction. In order to ensure the safety of the voice recognition function, the intelligent control system needs to be verified before starting the escape function, only when the person in the vehicle says a specific keyword "start the escape system", the intelligent control system will start the seat adjustment function and the door opening function.

[0088] As can be seen from the above, the application has the function of voice wake-up safety device, the user can directly control the corresponding safety device to perform corresponding safety operation through language, which is convenient and fast, and improves the timeliness and convenience of escape in the case of injury or inconvenience of the person in the vehicle.

[0089] Referring to Figure 5 , Figure 5 A control method flow diagram of a vehicle safety device provided by an embodiment of the application, the method specifically includes the following steps:

[0090] S301, acquiring the collision signal collected by each collision sensor; wherein each collision sensor is pre-set at different detection positions of the vehicle;

[0091] S302, determining the collision force value according to the collision signal;

[0092] S303, comparing the collision force value with the collision force range to determine the collision severity of the vehicle; wherein the collision force range includes different collision force ranges corresponding to different collision severities;

[0093] S304, determining the first target safety device to be triggered according to the collision severity; wherein the first target safety device is at least one of the alarm device, the airbag device, the seat adjustment device, and the door opening device;

[0094] S305, control the first target safety device to perform a corresponding safety operation.

[0095] In the present application, when determining the collision severity, the collision force value in the collision signal and the collision force range can be determined. The collision force range is a range corresponding to different collision severities, which can be set according to actual conditions. For example, the collision severity is set to include light collision, moderate collision, and severe collision, the collision force range corresponding to light collision is that the collision force value is less than or equal to 50kN (kilogram Newton), the collision force range corresponding to moderate collision is that the collision force value is greater than 50kN and less than or equal to 150kN, and the collision force range corresponding to severe collision is that the collision force value is greater than 150kN. Therefore, after determining the collision force value according to the collision signal, the collision force value is compared with the above-mentioned collision force range, and the collision severity corresponding to the matched collision force range is taken as the collision severity corresponding to this collision.

[0096] Referring to Figure 6 , Figure 6 A schematic diagram of an overall control process is provided for the embodiments of the present application. After the collision sensor detects the collision, the collision signal is sent to the intelligent control system. If the intelligent control system determines that the collision force value is less than or equal to 50kN (kilogram Newton), it is determined to be a light collision. In this range, the collision is relatively light, the vehicle structure is not severely damaged, and the risk of injury to the passengers in the vehicle is low. At this time, the intelligent control system only needs to control the alarm device to issue an alarm to remind the passengers in the vehicle. The alarm reminds the passengers to pay attention to the collision situation, checks whether they are injured, and prepares to take further action through sound, light or display screen prompt, etc.

[0097] If the intelligent control system detects that the collision force value is greater than 50kN and less than or equal to 150kN, it is determined to be a moderate collision. In this range, the collision is relatively serious, the vehicle structure may be deformed to a certain extent, and the risk of injury to the passengers in the vehicle increases. At this time, the intelligent control system can control the alarm device to issue a stronger alarm in order to attract the passengers' attention and prompt them to take escape measures as soon as possible; at the same time, the intelligent control system also needs to control the airbag device to pop up the airbag, and the pop-up of the airbag can provide additional protection for the passengers and reduce the risk of injury to the head, chest and other key parts.

[0098] If the intelligent control system detects that the collision force value is greater than 150kN, it is determined that it is a severe collision at this time, and in this range, the collision is very serious, the vehicle structure may be severely damaged, and the risk of passengers being trapped is extremely high. At this time, the intelligent control system controls the alarm device to issue a stronger alarm, and controls the airbag device to pop out the airbag at the same time, and also needs to control the seat adjustment device to adjust the seat position to provide more escape space for the passengers, control the door opening device to open the door to help the passengers leave the vehicle as soon as possible. And, the application also needs to detect whether the seat control motor is failed, if not, the seat motor starts to move backward after receiving the control system instruction, if failed, the seat hydraulic system is started to adjust the seat position; the application also needs to detect whether the electromagnetic door opening device is failed, if not, the electromagnetic device generates a strong magnetic force to open the door, if failed, the mechanical door opening device is started to open the door.

[0099] As can be seen from the above, the application provides an automobile intelligent escape system based on seats and doors, which can accurately detect collision signals through collision sensors arranged at the front, rear and both sides of the vehicle body, and take different safety measures according to the severity of the collision, such as issuing an alarm, popping out a safety airbag, starting seat adjustment and door opening, etc. Escape function, providing all-round safety protection for passengers in the vehicle. The intelligent control system has a voice recognition function, and after the collision occurs, if the passengers need to start the seat adjustment and door opening escape function, the function can be awakened by voice, which is convenient and fast, especially in the case of injured or disabled passengers, improves the timeliness and convenience of escape. The front seat adjustment module has two schemes of control motor and hydraulic system, and the door opening module has two schemes of electromagnetic door opening device and mechanical door opening device, which enhances the reliability of the automobile escape system.
