[0002] The safety belt of a vehicle plays a crucial role in the safety of a user, but in some extreme accidents, the safety belt can also cause secondary injuries to the user. For example, when a vehicle collision accident occurs, the safety belt of the vehicle is generally directly controlled to enter a mechanical locking state. However, in the event of an extreme accident such as a vehicle collision, rollover, etc., leading to thermal runaway of the power battery and fuel leakage and fire of the vehicle, the mechanical locking state of the safety belt will hinder the passengers in the vehicle from escaping quickly.

[0003] At present, the solution to this scenario is to directly cut off the safety belt after the vehicle collision. However, directly cutting off the safety belt can also cause secondary injuries to the user in the vehicle. SUMMARY

[0004] In view of the above problems, the present application provides a safety belt control method and device based on a vehicle emergency state, a vehicle and a computer readable storage medium, which can solve the problem of secondary injuries to passengers caused by cutting off the safety belt in an extreme accident of a vehicle, and improve the safety of passengers in an extreme accident of a vehicle.

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0025] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0026] The flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0027] In this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0028] Currently, in vehicle collisions, to prevent secondary injuries to occupants, seat belts are typically mechanically locked after a collision. However, in extreme accidents such as vehicle collisions and rollovers leading to battery thermal runaway or fuel leaks and fires, the mechanically locked seat belts can hinder occupants' rapid escape and may also cause secondary injuries.

[0029] In this scenario, the usual solution is to cut the seatbelt immediately after a collision and when the vehicle's speed is detected to be zero. However, in real-world situations, cutting the seatbelt directly may cause further injury to the occupants of the vehicle.

[0030] In view of this, to address the aforementioned problems, this application proposes a seatbelt control method based on vehicle emergency conditions to solve the problem of secondary injuries to occupants caused by seatbelt disconnection in extreme vehicle accidents, thereby improving occupant safety in such accidents. The executing entity of the seatbelt control method based on vehicle emergency conditions can be a terminal device, server, body domain controller, cockpit domain controller, or other processing device. The terminal device can be user equipment (UE), computer, mobile device, user terminal, terminal, cellular phone, personal digital assistant (PDA), handheld device, computing device, in-vehicle device, wearable device, etc. In some possible implementations, this seatbelt control method based on vehicle emergency conditions can be implemented by a processor calling computer-readable instructions stored in memory.

[0031] Specifically, please refer to, for example Figure 1 As shown in this embodiment, the seatbelt control method based on vehicle emergency conditions includes the following steps: Step S100: When the vehicle is in an emergency state, obtain the current state of the vehicle and the occupant status in the cabin.

[0032] The emergency states described here can be, but are not limited to, battery pack thermal runaway, fire, rollover, water-related accidents, and collisions, depending on the specific application scenario. This is merely an illustrative example and not a specific limitation. It should be understood that battery pack thermal runaway can be detected by the vehicle's BMS (Battery Management System), fire can be detected by temperature sensors and infrared cameras, and rollover, water-related accidents, and collisions can be detected by cameras, radar sensors, and IMUs (Inertial Measurement Units). The detection methods for battery pack thermal runaway, fire, rollover, water-related accidents, and collisions described here are merely illustrative examples and not specific limitations.

[0033] Occupant status includes occupant seating status and occupant mental status; occupant seating status refers to the seat position of the occupant in the vehicle cabin and the locking status of the seat belt; occupant mental status refers to whether the occupant in the vehicle cabin is awake or unconscious.

[0034] In this embodiment, to obtain and confirm the vehicle's emergency status and its current state under the emergency status, the embodiment further includes: obtaining the vehicle's emergency status to confirm that the vehicle's emergency status is one or more of the following: battery pack thermal runaway, fire accident, rollover accident, water accident, and collision accident; and then, based on the obtained vehicle emergency status, obtaining the vehicle's body posture and vehicle speed under the emergency status to determine whether the vehicle's current state is normal or abnormal. This embodiment facilitates the subsequent selection and execution of corresponding emergency strategies based on the vehicle's normal or abnormal state, as well as the occupant's seating status and mental state within the vehicle's cabin, thus improving the accuracy of vehicle emergency strategy execution.

[0035] Step S200: Execute the vehicle's emergency strategy based on the vehicle's current state and the occupant's state in the cabin.

[0036] In conjunction with the above embodiments, after obtaining information that the vehicle is in an emergency state such as battery pack thermal runaway, fire, rollover, water submersion, and / or collision, in order to more accurately determine the vehicle's current state based on the vehicle's posture and speed in the emergency state, and to combine the vehicle's current state, occupant seating status, and occupant mental state to execute corresponding emergency strategies; please continue to refer to... Figure 2 As shown, embodiments of this application further include: Step S210: If the current state of the vehicle is normal, then execute the vehicle's emergency strategy according to the normal state of the vehicle and the state of the occupants in the cabin. Step S220: If the current state of the vehicle is abnormal, then implement the vehicle's emergency strategy based on the abnormal state of the vehicle and the occupant status in the cabin.

[0037] If, after experiencing emergency states such as battery pack thermal runaway, fire, rollover, water submersion, and / or collision, the vehicle speed is detected to be less than or equal to a preset speed and the vehicle body tilt angle is less than or equal to a preset angle, then the vehicle's current state is determined to be normal. At this time, the vehicle's emergency strategy is executed based on the normal state of the vehicle and the occupant status in the cabin, and the corresponding emergency strategy determines whether to execute the target seat's seatbelt unlocking command and controls the target seat's seatbelt to unlock.

[0038] If, after experiencing emergency conditions such as battery pack thermal runaway, fire, rollover, water submersion, and / or collision, the vehicle's speed exceeds a preset speed, or its tilt angle exceeds a preset angle, the vehicle's current state is determined to be abnormal. In this case, the vehicle's emergency strategy is executed based on the abnormal state and the occupant status within the cabin. The strategy determines whether to execute the seatbelt unlock command for the target seat and controls its unlocking. It should be understood that if the vehicle is in a rollover state, an inverted chassis state, or similar situations where the tilt angle exceeds the preset angle, the vehicle's current state is considered abnormal.

[0039] It should be noted that the preset vehicle speed in the above embodiments may be, but is not limited to, 0 km / h, 1 km / h, 3 km / h, 5 km / h, etc., and the preset angle may be, but is not limited to, 10°, 15°, 18°, etc. The preset vehicle speed and preset angle here are just examples and are not specifically limited.

[0040] For example, if the vehicle is in a rollover accident emergency state, with a preset speed of 3 km / h and a preset angle of 15°, then after the rollover accident, the vehicle's speed and body tilt angle are detected. If the detected vehicle speed is 1 km / h and the body tilt angle is 5°, then the vehicle speed is less than the preset speed and the body tilt angle is less than the preset angle. Therefore, the vehicle's current state is determined to be normal. At this point, the vehicle's emergency strategy is executed based on the normal state of the vehicle and the occupant status within the cabin, according to the... The corresponding emergency strategy determines whether to execute the seat belt unlock command for the target seat and controls the seat belt of the target seat to unlock. If the vehicle speed is detected to be 10 km / h, or the vehicle body tilt angle is 20°, then the vehicle speed is greater than the preset speed, or the vehicle body tilt angle is greater than the preset angle, and the current state of the vehicle is determined to be abnormal. At this time, the vehicle's emergency strategy is executed according to the abnormal state of the vehicle and the state of the occupants in the cabin, and the corresponding emergency strategy determines whether to execute the seat belt unlock command for the target seat and controls the seat belt of the target seat to unlock.

[0041] It should be noted that the vehicle speed can be obtained, but is not limited to, through vehicle speed sensors, GPS (Global Positioning System), etc., and the tilt angle of the vehicle body can be obtained, but is not limited to, through radar sensors, IMU, etc. The vehicle speed and body attitude mentioned here are for illustrative purposes only and are not specifically limited.

[0042] Step S300: If it is found that the seat belt of the target seat is not unlocked, a seat belt blow-off command is issued to control the seat belt of the target seat to blow off.

[0043] In conjunction with the above embodiments, the target seat's seatbelt unlocking command is determined according to the corresponding emergency strategy. After the target seat's seatbelt is unlocked, if it is found that the target seat's seatbelt is not unlocked and remains locked, a seatbelt fuse-off command is issued to control the target seat's seatbelt to fuse.

[0044] It should be noted that in order to achieve the seat belt meltdown of the target seat, a fuse is installed in the seat belt device corresponding to each seat in the vehicle. In the event that the seat belt fails to unlock and deploy when the vehicle is in an emergency, the fuse in the seat belt device will directly melt the seat belt.

[0045] For example, in the seat belt device, the fuse can be installed on each corresponding seat belt tensioner, with the seat belt passing through the fuse. When the vehicle is in normal use, the use of the seat belt is not affected. In an emergency, if the seat belt cannot be unlocked and deployed, a seat belt fuse-breaking command is sent to the fuse of the corresponding seat belt of the target seat. This causes the fuse to connect to the low-voltage power supply of the entire vehicle, generating a large amount of heat to melt the corresponding seat belt of the target seat, facilitating the rapid escape of the occupant of the target seat and the rescue of the occupant.

[0046] The seatbelt control method based on vehicle emergency conditions in this application embodiment can, when the vehicle is in an emergency, selectively unlock the seatbelt of the target seat based on the current state of the vehicle and the occupant's seating status, and control the seatbelt to melt if the corresponding seatbelt is not unlocked. This avoids the problem of all seatbelts melting in an emergency and controls subsequent maintenance costs. At the same time, it further confirms whether the corresponding seatbelt needs to be unlocked or even melted based on the occupant's mental state, which can solve the problem of secondary injury to occupants caused by cutting seatbelts in extreme vehicle accidents and improve occupant safety in extreme vehicle accidents.

[0047] In an exemplary embodiment, in order to accurately determine the target seat where the occupant is located in the vehicle cabin, and to implement targeted emergency strategies for the target seat to precisely improve the safety of the occupant in the target seat, the seat belt control method based on the vehicle emergency state of this application further includes the following steps: Determine the occupant seating status and mental state within the cabin, depending on whether the vehicle is currently in a normal or abnormal state. If the occupant seating status indicates that there is an occupant in the target seat of the vehicle and the target seat is in the seat belt locked state, then the vehicle's emergency strategy will be executed according to the occupant's mental state.

[0048] In this embodiment, after determining the current state of the vehicle by vehicle speed and vehicle posture, regardless of whether the current state of the vehicle is normal or abnormal, it is necessary to further confirm the occupant's seating status and mental state in the cabin. Here, it is necessary to detect and confirm whether each seat in the vehicle cabin has an occupant and the seat belt locking status of the target seat corresponding to the occupant. When it is confirmed that there is an occupant in the target seat and the target seat is in the seat belt locking state, the corresponding emergency strategy is then executed according to the mental state of the occupant in the target seat.

[0049] It should be noted that if a seat in the vehicle cabin is occupied and the seatbelt corresponding to that seat is not locked, the emergency strategy will not include the seatbelt unlocking command for that seat; if a seat in the vehicle cabin is unoccupied and the seatbelt corresponding to that unoccupied seat is locked, the emergency strategy will not include the seatbelt unlocking command for that seat; if a seat in the vehicle cabin is unoccupied and the seatbelt corresponding to that unoccupied seat is not locked, the emergency strategy will not include the seatbelt unlocking command for that seat.

[0050] In the above embodiments, the detection of whether each seat in the vehicle cabin has an occupant can be performed by a pressure sensor installed on each seat in the vehicle, or by a camera in the vehicle cabin, to confirm whether an occupant is sitting in the seat, thereby facilitating subsequent targeted control of the seat belts corresponding to the seats with occupants.

[0051] For example, if the seat pressure sensor, cabin camera, or other means detect that the driver's seat, front passenger seat, and left rear seat are occupied, and the driver's and front passenger seats are in the locked seatbelt position while the left rear seat is in the unlocked position, then the corresponding emergency strategy will be executed based on the mental state of the occupant in the driver's seat, front passenger seat, and left rear seat. It should be understood that, since the left rear seat's seatbelt is unlocked, the emergency strategy does not include a command to unlock the left rear seat's seatbelt.

[0052] In one exemplary embodiment, in order to accurately control the vehicle to execute corresponding emergency strategies based on the mental state of the occupants in the vehicle cabin, after determining that the vehicle is in a normal state, please refer to... Figure 3 As shown, the seat belt control method based on vehicle emergency conditions in this application further includes the following steps: Step S211: When the current state of the vehicle is normal, determine the occupant seating status and occupant mental state in the cabin. Step S212: If the occupant seating status indicates that there is an occupant in the target seat of the vehicle and the target seat is in the seat belt locked state, then the emergency strategy of the vehicle is executed according to the occupant's mental state. Step S213: If the occupant is in a conscious state, an unlocking request and warning message are sent to control the seat belt of the target seat to unlock and send a remote distress message according to the occupant's instructions. Step S214: If the occupant is in a coma, a wake-up message is sent for a first preset duration. Step S215: If the occupant's mental state remains unconscious after the first preset time period, then issue a seatbelt unlocking command for the target seat and send a remote distress signal.

[0053] In this embodiment, after determining the normal state of the vehicle by vehicle speed and vehicle posture, and confirming the occupant's seating status in the cabin, the mental state of the occupant in the corresponding target seat in the cabin is further confirmed, and then the corresponding emergency strategy is executed according to the occupant's mental state, such as being awake or unconscious.

[0054] For example, if it is determined that there are occupants in the driver's seat and front passenger seat in the vehicle cabin, and both seats are in the seatbelt-locked state, and if both occupants are conscious, an unlock request and warning message are issued to the occupants in the cabin requesting whether to unlock their seatbelts. If an occupant issues a seatbelt unlock command, the seatbelt of the target seat is unlocked, and remote assistance is simultaneously requested from emergency centers, vehicle manufacturers, vehicle after-sales service centers, etc. It should be understood that the warning message issued may include a voice reminder to the occupants to leave the vehicle in time.

[0055] If it is confirmed that there are occupants in the driver's and front passenger seats in the vehicle cabin, and both seats are in the seatbelt-locked position, and if both occupants are unconscious, a wake-up message will be sent to awaken them. If the occupants remain unconscious after a first preset duration of the wake-up message, a seatbelt unlock command will be issued to directly unlock the target seat's seatbelt. Simultaneously, a remote distress signal will be sent to the emergency center, vehicle manufacturer, and vehicle after-sales service center. It should be understood that the seatbelt unlock command for the target seat is issued when the vehicle is in a normal operating state.

[0056] Furthermore, after confirming that the vehicle is in normal condition, please refer to... Figure 4As shown, the seat belt control method based on vehicle emergency conditions in this application further includes the following steps: Step S221: When the current state of the vehicle is abnormal, determine the occupant seating status and mental state of the occupants in the cabin. Step S222: If the occupant seating status indicates that there is an occupant in the target seat of the vehicle and the target seat is in the seat belt locked state, then the emergency strategy of the vehicle is executed according to the occupant's mental state. Step S223: If the occupant is in a conscious state, an unlocking request and warning message are sent to control the seat belt of the target seat to unlock and send a remote distress message according to the occupant's instructions. Step S224: If the occupant is in a coma, a wake-up message is sent for a first preset duration. Step S225: If the occupant's mental state remains unconscious after the first preset time period, then wake-up messages and remote distress messages are continuously sent.

[0057] In this embodiment, after determining the abnormal state of the vehicle by measuring vehicle speed and vehicle posture, and confirming the occupant's seating status in the cabin, the mental state of the occupant in the corresponding target seat in the cabin is further confirmed. Then, the corresponding emergency strategy is executed based on the occupant's mental state, such as being awake or unconscious.

[0058] For example, if it is determined that there are occupants in the driver's seat and front passenger seat in the vehicle cabin, and both seats are in the seatbelt-locked state, and if both occupants are conscious, an unlock request and warning message are issued to the occupants in the cabin requesting whether to unlock their seatbelts. If an occupant issues a seatbelt unlock command, the seatbelt of the target seat is unlocked, and remote assistance is simultaneously requested from emergency centers, vehicle manufacturers, vehicle after-sales service centers, etc. It should be understood that the warning message issued may include a voice reminder to the occupants to leave the vehicle in time.

[0059] If it is confirmed that there are occupants in the driver's seat and front passenger seat in the vehicle cabin, and both seats are in the seatbelt-locked position, and if both occupants are unconscious, a wake-up message will be sent to wake them up. If the occupants remain unconscious after the wake-up message has been sent for a first preset duration, the wake-up message will continue to be sent to wake them up, and at the same time, remote distress messages will be sent to the emergency center, vehicle manufacturer, vehicle after-sales service center, etc.

[0060] It should be noted that if the vehicle is in an abnormal state and both the driver's and front passenger's occupants are unconscious and cannot be awakened, attempting to unlock the seatbelt of the target seat could result in secondary injury to the occupants. Therefore, in this situation, a seatbelt unlock command should not be issued to unlock the target seat's seatbelt.

[0061] In the above embodiments, the first preset duration can be, but is not limited to, 30s, 60s, 100s, etc., and can be set according to the actual application scenario. This is only an illustrative example and is not specifically limited.

[0062] In an exemplary embodiment, to prevent the seat belt of the target seat from failing to unlock properly, the seat belt control method based on vehicle emergency conditions in this application further includes the following steps: After the vehicle's emergency strategy is executed, the seatbelt unlocking status of the target seat is acquired in real time. If the seat belt of the target seat is not unlocked within a second preset time period, a seat belt fuse-off command for the target seat is issued. The seatbelt of the target seat is controlled to melt according to the seatbelt melt command.

[0063] In this embodiment, after executing the seatbelt unlock command corresponding to the target seat in the vehicle emergency strategy, the seatbelt unlock status of the target seat continues to be acquired in real time. If the seatbelt of the target seat is not unlocked within a second preset time period, a seatbelt blow-off command is issued to control the seatbelt to blow off. Through this embodiment, when the seatbelt of a seat in the vehicle cabin cannot be unlocked, the seatbelt of the seat in which the occupant is located is controlled to blow off, avoiding the blow-off of all seatbelts in the vehicle, which would lead to increased maintenance costs later. At the same time, the safety of the occupants in the vehicle cabin is improved.

[0064] It should be noted that if the seatbelt of the target seat cannot be unlocked normally, but the seat in the vehicle cabin is occupied and the seatbelt of that occupant is not locked, then the target seat does not need to trigger the seatbelt deactivation command; if the seat in the vehicle cabin is unoccupied and the seatbelt of that unoccupied seat is locked, then the target seat does not need to trigger the seatbelt deactivation command; if the seat in the vehicle cabin is unoccupied and the seatbelt of that unoccupied seat is not locked, then the target seat does not need to trigger the seatbelt deactivation command.

[0065] In the above embodiments, scenarios where the seat belt in the vehicle cabin cannot be unlocked normally may include: the seat belt buckle is deformed or squeezed, preventing it from popping out; the seat belt buckle is not deformed, but the buckle's pop-out area is blocked by foreign objects, preventing it from popping out; or the seat belt buckle has a mechanical malfunction and cannot function properly. The second preset duration can be, but is not limited to, 3s, 5s, 10s, etc., and can be set according to the actual application scenario. The scenarios where the seat belt cannot be unlocked normally and the second preset duration are illustrative examples and are not specifically limited.

[0066] Figure 5 A schematic diagram of an embodiment of the seatbelt control device based on a vehicle emergency situation, according to this application, is shown. Please refer to... Figure 5 As shown, the seat belt control device 400 based on vehicle emergency status includes a status acquisition module 410, a strategy execution module 420, and a circuit breaker control module 430. The status acquisition module 410 is used to acquire the current status of the vehicle and the status of the occupants in the cabin when the vehicle is in an emergency state; wherein, the occupant status includes the occupant's riding status and the occupant's mental state. The strategy execution module 420 is used to execute the vehicle's emergency strategy based on the vehicle's current state and the occupant's state in the cabin; wherein the emergency strategy includes a seatbelt unlocking command for the target seat; The fuse control module 430 is used to issue a seat belt fuse control command to control the seat belt of the target seat to fuse if it is found that the seat belt of the target seat is not unlocked.

[0067] It should be noted that the seat belt control device 400 based on vehicle emergency status provided in the above embodiments and the seat belt control method based on vehicle emergency status provided in the aforementioned embodiments belong to the same concept. The specific way in which each module and unit performs operations has been described in detail in the method embodiments, and will not be repeated here.
