[0002] At present, with the continuous development of automobile technology, the safety of vehicles has gradually received attention. However, in the event of a collision, especially for rear passengers in six-seater or seven-seater models, there are still many challenges in the escape process.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0018] The disclosed embodiment provides a vehicle escape method, which aims to improve the escape efficiency and safety of rear passengers in the event of a collision. With the continuous advancement of automobile technology, vehicle safety has become a focus of public attention. However, after a collision, existing vehicle designs, especially for rear passengers in six-seat and seven-seat models, often face problems such as complex escape routes and slow speeds, which seriously affect the passengers' chances of survival. In order to solve this problem, the disclosed method obtains the collision data and posture data of the vehicle in real time, quickly determines the current state of the vehicle, and when a collision is confirmed, quickly opens the locking device of the tailgate and folds down the rear seats to form a safe escape route. It not only simplifies the escape process, but also effectively protects the lives of passengers in extreme cases, and has important practical value and social significance. Figure 1 is a schematic diagram of a vehicle escape method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the vehicle escape method includes: Step S101, acquiring collision data and posture data of a vehicle, wherein the posture data includes a linear acceleration and a rotational angular velocity of the vehicle in a three-dimensional space; Step S102, determining the current state of the vehicle according to the collision data and / or the posture data; Step S103, when it is detected that the current state of the vehicle is that the vehicle has collided, the tailgate of the vehicle is unlocked and the rear seats of the vehicle are folded down to form a rear escape route for the vehicle.

[0019] Involving step S101, the collision data and posture data of the vehicle are obtained in real time, which can be obtained through the vehicle's control system or other monitoring means, for example, through a central collision sensor and a six-axis acceleration sensor. Collision data refers to information related to the collision event recorded when the vehicle collides, including collision intensity and collision direction. Among them, the collision intensity is an indicator of the severity of the collision event, which is expressed by the change in acceleration and can be calculated by the instantaneous acceleration change detected by the sensor. The collision direction refers to the direction in which the vehicle is impacted during the collision. For example, a frontal collision, a side collision, or a rear collision, etc., different collision directions will have different degrees of impact on the vehicle and passengers. The posture data is used to describe the dynamic information of the position and direction of the vehicle in three-dimensional space, including linear acceleration and rotational angular velocity. Among them, linear acceleration refers to the acceleration change of the vehicle in the three axes of X, Y, and Z. It reflects the motion state of the vehicle in different directions. The X-axis acceleration represents the acceleration in the front and rear directions, a positive value represents acceleration, and a negative value represents deceleration. The Y-axis acceleration represents the acceleration in the left and right directions, which will change significantly when turning or skidding. The Z-axis acceleration represents the acceleration in the up and down directions, which changes when the vehicle jumps or bumps. The rotational angular velocity refers to the rotation rate of the vehicle around the X, Y, and Z axes, and is used to describe the rotational state of the vehicle in space. The angular velocity around the X-axis represents the rate at which the vehicle tilts forward and backward. A positive value indicates that the front of the vehicle rises, and a negative value indicates that the front of the vehicle falls. The angular velocity around the Y-axis represents the rate at which the vehicle rolls left and right. A positive value indicates that the vehicle rolls to the right, and a negative value indicates that it rolls to the left.

[0020] Involving step S102, the acquired collision data and posture data are fused and analyzed, or the current state of the vehicle is determined based on the posture data (the linear acceleration and rotational angular velocity of the vehicle in three-dimensional space). The intensity of the collision can be determined based on the acceleration change reflected by the collision data. For example, if the X-axis acceleration exceeds a certain threshold (such as 8g), it can be determined that the vehicle has experienced a collision, and it is necessary to further determine the severity of the collision in combination with the posture data, that is, to further determine the dynamic state of the vehicle. For example, if the Y-axis acceleration shows a large positive value, it means that the vehicle is rolling to the right; if the Z-axis acceleration fluctuates significantly, it means that the vehicle is experiencing bumps or jumps; if the X-axis angular velocity changes significantly, it means that the vehicle is braking or turning suddenly. Combined with the collision intensity and the posture change reflected by the posture data, it is determined whether the vehicle has collided. If the collision intensity reaches the set threshold, and the posture data shows that the vehicle has signs of rolling or tilting, it can be determined that the vehicle has a serious collision. It is also possible to analyze the linear acceleration and rotational angular velocity in the posture data separately to obtain an index of the acceleration component to determine whether the vehicle has a collision event.

[0021] Involving step S103, emergency escape measures are performed according to the current state of the vehicle determined in step S102 (i.e., confirming that the vehicle has collided). Specifically, the lock of the tailgate of the vehicle is immediately opened, and the rear seats are folded down, and the rear seats can be seats in the third row. The lock of the tailgate refers to a mechanical or electronic device used to fix and lock the rear tailgate (i.e., the trunk door or rear door) of the vehicle. Its main function is to ensure that the tailgate remains closed during driving to prevent the tailgate from opening accidentally. In a severe collision, the structure of the vehicle may be deformed, and the lock tongue of the tailgate may be stuck and cannot be opened by conventional means. In this case, if the passengers need to escape, they will face great difficulties. The blasting can be performed by an blasting device configured at the lock of the tailgate. At the same time, the rear seats are folded down. After the seats are folded down, the tailgate opens to form a spacious escape passage, through which the rear passengers can quickly escape from the vehicle. In the disclosed embodiment, the two actions of opening the tailgate and locking it and folding the rear seats are performed in a coordinated manner. Passengers do not need to wait for the tailgate to open or the seats to fold down, but can escape at the same time, reducing the risk of injury caused by panic or confusion. If the tailgate is only opened without folding the seats, the passengers may be trapped due to the small space; conversely, if the seats are only folded down without opening the tailgate, they cannot escape. Therefore, the two actions are performed at the same time to ensure that passengers can pass through the escape passage smoothly.

[0022] The present disclosure obtains the collision data and posture data of the vehicle in real time, and promptly and accurately determines the current state of the vehicle, so as to react quickly at the moment of collision, greatly reducing the escape time of passengers in emergency situations and improving the efficiency of escape. Secondly, after confirming that the vehicle has collided, the locking device of the tailgate is immediately opened to ensure that the rear passengers can quickly open the escape passage. At the same time, the rear seats are folded down to be flush with the trunk to form a spacious escape path, further simplifying the escape process for passengers. It effectively solves the problems of cumbersome paths and slow speeds in traditional vehicle escapes, especially in extreme cases such as vehicle fires or secondary collisions, and can significantly improve the survival rate of passengers.

[0023] Exemplarily, determining the current state of the vehicle based on the collision data and / or the posture data includes: determining the intensity of a collision suffered by the vehicle based on the collision data of the vehicle; when the intensity of a collision suffered by the vehicle is greater than or equal to a preset collision intensity threshold, determining the current motion posture of the vehicle based on the linear acceleration and rotational angular velocity of the vehicle in three-dimensional space, the motion posture including smooth, tilted and rolling; when the motion posture is detected to be tilted or rolled, determining the current state of the vehicle as a collision of the vehicle.

[0024] In the disclosed embodiment, the fusion analysis based on the collision data and the posture data can effectively judge the current state of the vehicle, so as to quickly respond and trigger the escape measures. The main purpose of the fusion analysis is to more accurately identify whether the vehicle is in a collision state, the severity of the collision, and the current posture of the vehicle (such as stable, tilted or rolling). Specifically, after the vehicle has a collision event, the vehicle can obtain the collision data and posture data through the collision sensor and the six-axis acceleration sensor respectively, and calculate the collision intensity of the vehicle according to the collision data. Assuming that the preset collision intensity threshold is 8g, once it is detected that the collision intensity of the vehicle reaches or exceeds the collision intensity threshold, it can be preliminarily judged that the vehicle may be experiencing a collision event. In fact, sometimes some collisions occur during driving, such as friction with the guardrail. Therefore, there may be a risk of misjudgment based on the judgment of the collision intensity alone, and it is necessary to further combine the posture data to confirm whether the vehicle is indeed in a major collision. The motion posture of the vehicle is obtained by judging the linear acceleration and rotational angular velocity of the vehicle to determine whether the motion state of the vehicle is stable, tilted or rolling, and the corresponding posture matching can be performed according to the preset acceleration-posture matching table. Among them, the stable state indicates that the vehicle state may be a minor collision, and the escape operation may not be performed. The tilted state indicates the posture change caused by sudden braking or the front and rear tilt of the vehicle. The rollover state indicates that the vehicle is in a rollover state. When the vehicle's motion posture is detected to be tilted or rolled, it indicates that the vehicle is experiencing a serious collision at this time. For example, suppose that in a collision, the collision intensity is detected to be 9g (exceeding the preset 8g), and the current motion posture of the vehicle is determined based on the posture data to indicate that the vehicle has a large tilt or rollover. At this time, the current motion state of the vehicle is judged as "collision occurs" and escape measures are immediately executed.

[0025] The present disclosure integrates collision data and posture data, and determines the current state of the vehicle through comprehensive analysis of the collision data and posture data. When the collision intensity reaches the preset collision intensity threshold, and the posture data indicates that the vehicle is in an unstable state, it can accurately determine that the vehicle has collided, and then take corresponding emergency escape measures. The multi-level judgment logic of the present disclosure can respond quickly after an accident occurs, and maximize the safety of passengers without false triggering.

[0026] Exemplarily, determining the current state of the vehicle based on the collision data and / or the posture data includes: determining the acceleration components of the vehicle along a first direction, a second direction, and a third direction, respectively, based on the linear acceleration and the rotational angular velocity of the vehicle in three-dimensional space, wherein the first direction, the second direction, and the third direction are perpendicular to each other; when at least one of the acceleration components of the vehicle along the first direction, the second direction, and the third direction meets a corresponding preset collision condition, determining the current state of the vehicle as a collision of the vehicle.

[0027] In addition to the fusion judgment of collision data and posture data described above, the disclosed embodiment is also intended to respond to emergencies by instantly triggering escape measures. The collision state of the vehicle is identified by relying on the linear acceleration and rotational angular velocity of the vehicle in three-dimensional space in the posture data. There is no need to first detect the exceeding of the collision intensity threshold, but to directly judge by the acceleration change. It is suitable for scenarios that require extremely fast response, and can immediately trigger escape measures when abnormal changes in the vehicle posture are detected.

[0028] After acquiring the posture data, the acceleration change of the vehicle in the three-dimensional space is analyzed to determine whether the vehicle is likely to be in a collision state. The judgment is based on the acceleration components of the vehicle in three directions calculated according to the linear acceleration and rotational angular velocity of the vehicle in the three-dimensional space, that is, the acceleration component in the first direction (such as the X-axis) corresponds to the front and rear directions of the vehicle. For example, when a frontal or rear-end collision occurs, the acceleration of the X-axis will suddenly increase. The acceleration component in the second direction (such as the Y-axis) corresponds to the left and right directions of the vehicle. When a side collision occurs, the acceleration of the Y-axis will change significantly. The acceleration component in the third direction (such as the Z-axis) corresponds to the up and down directions of the vehicle. In order to achieve instantaneous judgment, this method pre-sets corresponding preset conditions (collision conditions) for the acceleration components in each direction, that is, when the acceleration reaches a specific value in a certain direction, it can be judged that the vehicle is in an unstable state and there is a risk of collision. The setting of the judgment condition can be configured based on the physical characteristics, test data and safety requirements of the vehicle. When it is detected that the acceleration component in any direction meets the collision condition, the current state of the vehicle is immediately determined as "collision occurs" and emergency measures are quickly triggered.

[0029] The above steps achieve a quick judgment of the vehicle collision status through instantaneous analysis of three-dimensional acceleration and rotational angular velocity. There is no need for complex collision intensity calculations, and quick judgment is made directly based on acceleration conditions in all directions, which is more suitable for emergency scenarios that require high sensitivity and immediate response. The escape response speed in emergency situations is significantly improved, ensuring that passengers can quickly evacuate the vehicle in dangerous situations.

[0030] Exemplarily, when it is detected that the current state of the vehicle is that the vehicle has collided, the lock of the tailgate of the vehicle is opened and the rear seats of the vehicle are folded down, including: when it is detected that the current state of the vehicle is that the vehicle has collided, the airbag of the vehicle is inflated, and the explosives inside the tailgate lock blasting device are ignited, and the lock of the tailgate of the vehicle is opened by the high-temperature and high-pressure gas generated by the ignition of the explosives; and the rear seats of the vehicle are driven to fold back at a constant speed within a preset time to an angle flush with the trunk of the vehicle.

[0031] After detecting that the vehicle has collided, a series of emergency measures are immediately implemented to help the passengers in the vehicle escape quickly. Specifically, once the current state of the vehicle is determined to be a collision, the vehicle's airbag system is first triggered. The inflation action of the airbag can provide preliminary protection for the passengers, reduce the direct damage to the passengers caused by the collision, and win more escape time for the passengers. In the disclosed embodiment, the airbag is installed in front of the driver and co-pilot seats to protect the front passengers. The locking device of the tailgate is used to keep the tailgate (trunk door) of the vehicle closed to ensure safety during driving. However, in the event of a serious collision of the vehicle, the body structure may be deformed, causing the locking mechanism to get stuck and the tailgate cannot be opened in a conventional manner. To cope with this situation, the vehicle is equipped with a small blasting device at the locking position, which contains a small amount of explosives and is configured to be activated only when triggered after the collision, and will not be accidentally opened during normal use. When a collision is detected and it is confirmed that emergency escape is required, a signal is sent to ignite the explosives inside the blasting device. The combustion of explosives produces high-temperature and high-pressure gases, which quickly destroy the locking mechanism through expansion force, so that the lock tongue of the tailgate is separated from the fixed part of the vehicle body and the locking state is released. In this way, the lock of the tailgate is opened, and even if the vehicle body is severely deformed, the tailgate can be pushed or bounced open to form an escape path. At the same time, the rear seats of the vehicle (which can be the third row of seats) are controlled to fall backwards. This action is to quickly free up enough space after the tailgate is opened, so that passengers can escape through the trunk. Within the set preset time, the rear seats are folded down at a uniform speed. To prevent the rapid folding of the seats from causing secondary injuries to passengers (such as accidental pinching), the folding process can be driven by an electric motor or a hydraulic device, and the folding speed can be controlled according to the preset time. After folding, the seats are flush with the bottom plate of the trunk, forming a continuous and flat escape path. Even if the passengers in the car are frightened or injured due to the collision, they can slide out of the rear of the vehicle more easily, avoiding the difficulty of escape caused by the narrow space.

[0032] The above steps form a spacious escape passage in the shortest possible time by using an explosive device to unlock the tailgate and fold down the rear seats at a constant speed. Combined with the protective effect of the airbag, it minimizes the plight of passengers in the car after a collision, especially in the case of vehicle structural deformation, providing passengers with an effective means of escape.

[0033] The present invention obtains the collision data and posture data of the vehicle in real time, and promptly and accurately determines the current state of the vehicle, so as to react quickly at the moment of collision, greatly reducing the escape time of passengers in emergency situations and improving the efficiency of escape. Secondly, after confirming that the vehicle has collided, the locking device of the tailgate is immediately opened to ensure that the rear passengers can quickly open the escape passage. At the same time, the rear seats are folded down to be flush with the trunk to form a spacious escape path, further simplifying the escape process for passengers. It effectively solves the problems of cumbersome paths and slow speeds in traditional vehicle escapes, especially in extreme cases such as vehicle fires or secondary collisions, and can significantly improve the survival rate of passengers.

[0034] Figure 2 is a structural block diagram of a vehicle escape system provided by an embodiment of the present disclosure, such as Figure 2 As shown, the system is applied to the steps of executing the vehicle escape method, and the vehicle escape system includes: a central collision sensor 201, a six-axis acceleration sensor 202, a domain controller 203 and an execution module 204; the output ends of the central collision sensor 201 and the six-axis acceleration sensor 202 are respectively connected to the domain controller 203, and the input end of the execution module 204 is connected to the domain controller 203; the execution module 204 at least includes a tailgate locking blasting device 205 and a rear seat controller 206; The central collision sensor 201 is used to obtain collision data of the vehicle and send the collision data to the domain controller 203; The six-axis acceleration sensor 202 is used to obtain the posture data of the vehicle and send the posture data to the domain controller 203, wherein the posture data includes the linear acceleration and rotational angular velocity of the vehicle in three-dimensional space; The domain controller 203 is used to determine the current state of the vehicle according to the collision data and / or the posture data, and send a control instruction to the execution module 204 when it is detected that the current state of the vehicle is that the vehicle has collided; The tailgate locking blasting device 205 is used to respond to the control command and unlock the tailgate of the vehicle; The rear seat controller 206 is used to respond to the control instruction and fold down the rear seats of the vehicle.

[0035] The vehicle escape system obtains the collision data and posture data of the vehicle through a series of sensors, uses the domain controller to analyze and judge the data, and implements specific escape operations through the execution module, such as the explosion of the tailgate and the folding of the rear seats. The goal is to provide passengers with a fast and smooth escape channel after a serious vehicle collision, especially when the deformation of the vehicle structure may affect the opening of the door. Below, the various module components of the system are described in detail.

[0036] The central collision sensor 201 is used to detect relevant data when the vehicle collides, including the collision intensity and direction. The sensor can be installed at the front or center of the vehicle and obtains collision data by monitoring the acceleration change of the vehicle body when a collision occurs. The collision intensity is represented by the acceleration change. The central collision sensor 201 can detect the front, side or rear collision and send this data to the domain controller 203.

[0037] The six-axis acceleration sensor 202 is used to obtain the vehicle's posture data in real time, including the vehicle's linear acceleration and rotational angular velocity in three-dimensional space. The six-axis acceleration sensor 202 simultaneously monitors the vehicle's acceleration changes in the three axes of X, Y, and Z, as well as the rotational angular velocity around these three axes. The above data can be used to determine whether the vehicle is in a rollover, sharp turn, side slip, or collision.

[0038] The domain controller 203, as the control core of the vehicle escape system, is used to receive data from the central collision sensor 201 and the six-axis acceleration sensor 202, and determine whether the vehicle has collided or other abnormal conditions based on these data. The domain controller combines the collision data and the posture data for comprehensive analysis. Based on the set threshold and data analysis algorithm, the domain controller determines whether the vehicle has collided. When a collision is confirmed, the domain controller sends a control instruction to the execution module 204 to start the emergency escape measures.

[0039] The execution module 204 is responsible for executing specific escape operations. It receives control signals from the domain controller 203 and immediately executes relevant actions. Figure 2 , the execution module 204 at least includes a tailgate locking explosion device 205 and a rear seat controller 206. The tailgate locking explosion device 205 is used to open the locking device of the tailgate, so that the tailgate can be opened quickly after a collision, providing a trunk escape passage for passengers. The rear seat controller 206 is used to fold down the rear seats of the vehicle (which may be the third row of seats) to form an escape route.

[0040] The vehicle escape system provided in the embodiment of the present disclosure combines multiple sensors with intelligent control to realize automated emergency escape operations, providing a quick and effective escape route for passengers in the vehicle in extreme situations.

[0041] Exemplarily, the execution module 204 also includes an airbag control unit 207, the output end of which is connected to the tailgate locking blasting device; the tailgate locking blasting device is provided with explosives; the airbag control unit is used to respond to the control instruction to inflate the airbag of the vehicle; the airbag control unit is also used to forward the control instruction to the tailgate locking blasting device after inflating the airbag of the vehicle; the tailgate locking blasting device 205 is used to respond to the control instruction forwarded by the airbag control unit to open the lock of the tailgate of the vehicle by igniting the high-temperature and high-pressure gas generated by the explosives.

[0042] Figure 3 is a structural block diagram of another vehicle escape system provided by an embodiment of the present disclosure, such as Figure 3 As shown, the execution module 204 also includes an airbag control unit 207, and the airbag control unit 207 and the tailgate locking and blasting device 205 are connected to the domain controller 203 in a serial manner. The airbag control unit 207 is used to control the inflation of the airbag in time after the vehicle collides, and forward the control command to the tailgate locking and blasting device after the inflation is completed, so as to start the tailgate blasting device to open the tailgate and form an escape passage. When the domain controller 203 detects that the vehicle has a serious collision, it first sends a control command to the airbag control unit. In response to the control command, the airbag control unit 207 immediately inflates the airbag in the vehicle to protect the occupants in the vehicle from collision injuries. The inflation time of the airbag is very short, generally completed within milliseconds. After receiving the control command forwarded by the airbag control unit 207, the tailgate locking blasting device 205, based on the gas blasting technology, ignites the explosive to generate high-temperature and high-pressure gas, thereby unlocking the tailgate and opening the tailgate, providing passengers with a trunk escape passage. In a series connection, the airbag control unit 207 and the tailgate locking blasting device 205 form a linkage system. After a collision occurs, the inflation of the airbag and the opening of the tailgate are coordinated, which improves the overall efficiency of the system and enables passengers to obtain an escape passage in the shortest time. Since the airbag control unit will not open the tailgate blasting device in advance when the airbag is not fully inflated, it prevents misoperation in an emergency and ensures the safety of passengers.

[0043] The present invention adds a series interaction with the airbag control unit on the basis of the original tailgate locking explosion device, ensuring that the deployment of the airbag and the explosion of the rear seat locking work in a coordinated manner, forming a complete safety closed loop from protection to escape.

[0044] Exemplarily, the execution module further includes an airbag control unit 207, the input end of the airbag control unit 207 and the input end of the tailgate locking blasting device 205 are respectively connected to the domain controller; the tailgate locking blasting device 205 has explosives inside; The airbag control unit 207 is used to inflate the airbag of the vehicle in response to the control instruction; The tailgate locking blasting device 205 is used to respond to the control instruction and open the lock of the tailgate of the vehicle by igniting the high-temperature and high-pressure gas generated by the explosive.

[0045] Figure 4 is a structural block diagram of another vehicle escape system provided by an embodiment of the present disclosure, such as Figure 4 As shown, there are two connection modes involving the airbag control unit 207 and the tailgate locking blasting device 205 in the execution module, one is the series structure as described above, and the other is the parallel structure to be described here. In the parallel structure, the input ends of the airbag control unit 207 and the tailgate locking blasting device 205 are respectively connected to the domain controller 203, that is, the airbag control unit 207 and the tailgate locking blasting device 205 receive the control instruction at the same time. When the domain controller 203 detects that the vehicle has collided, it sends the control instruction to the airbag control unit 207 and the tailgate locking blasting device 205 at the same time. After receiving the instruction, the airbag control unit 207 immediately inflates the airbag of the vehicle to ensure that the passengers are fully protected in the event of a collision. The tailgate locking blasting device 205 receives the control instruction of the domain controller 203 at the same time, and ignites the internal explosives to generate high-temperature and high-pressure gas to open the lock of the tailgate, so that the tailgate can be opened to form an escape route. Airbag inflation and tailgate explosion are carried out simultaneously, that is, airbag deployment and tailgate opening are not dependent on the completion of a certain process, but are executed in parallel, which simplifies the process and ensures the rapid escape of passengers after a vehicle collision.

[0046] In the parallel structure, the airbag inflation and tailgate explosion are carried out at the same time; in the series structure, the airbag inflation must be completed first, and the tailgate explosion must be completed later. The series structure pays more attention to safety. The tailgate explosion is allowed only after the airbag is fully deployed, providing higher safety. The parallel structure improves the escape efficiency. The two operations occur in parallel, shortening the time for the escape channel to be opened. Therefore, the parallel structure is suitable for some scenarios with high requirements for escape speed, and the series structure is more suitable for scenarios that require high safety. Designers can make corresponding configurations according to the needs of actual applications.

[0047] Exemplarily, the domain controller includes a data fusion module; the data fusion module is used to determine the collision intensity of the vehicle based on the collision data of the vehicle; when the data fusion module detects that the collision intensity of the vehicle is greater than or equal to the preset collision intensity threshold, the data fusion module determines the current motion posture of the vehicle based on the linear acceleration and rotational angular velocity of the vehicle in three-dimensional space, and the motion posture includes smooth, tilted and rolling; when the data fusion module detects that the motion posture is tilted or rolled, the data fusion module determines the current state of the vehicle as a collision of the vehicle.

[0048] The data fusion module is used to integrate different data sources from the central collision sensor and the six-axis acceleration sensor, and judge and analyze the state of the vehicle based on these data to determine a collision event. The determination of a collision event has been described in detail in the description of the method embodiment, and will not be repeated here.
