[0028] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0029] The names of the messages or information exchanged between the multiple devices in the embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0030] Airbags are safety devices installed in vehicles. In the event of a collision, the airbags deploy to create a buffer between the occupant and the vehicle body, reducing the impact force and thus lowering the probability of injury.

[0031] An airbag has a protection zone; when the seat in the vehicle is within the protection zone of the airbag, the airbag can protect the occupant in the seat.

[0032] Normally, the position of an airbag is fixed, meaning that the airbag can only deploy in a fixed position.

[0033] For example, in a related art, a roof-mounted airbag is provided. This roof-mounted airbag includes an inflator bracket, an airbag module, an airbag, and a gas generator assembly. The inflator bracket is fixedly connected to the roof of the vehicle, and the airbag module is mounted on the inflator bracket. The airbag includes a driver's side protection chamber, a center protection chamber, and a passenger side protection chamber. The driver's side protection chamber communicates with the center protection chamber, and the center protection chamber communicates with the passenger side protection chamber. The airbag is housed within the roof-mounted airbag module. The gas generator assembly is disposed on the inflator bracket and communicates with the airbag to introduce a large amount of gas into the airbag upon triggering. In this roof-mounted airbag, by positioning the airbag at the front end of the roof and simultaneously providing frontal protection for both the driver and passenger, the airbag, after deployment, forms a raised structure between the driver and passenger to prevent a collision between them, thus providing more comprehensive protection for the front-seat occupants.

[0034] In another related technology, a roof-mounted occupant restraint system is provided for protecting a first and second occupant of a vehicle having a roof and a passenger compartment with a first seat and a second seat for accommodating the first and second occupants. The restraint system includes a first airbag and a second airbag mounted to the vehicle roof. Each of the first and second airbags has a stored state and is inflatable to a deployed state aligned with the corresponding first and second occupant. The deployed first and second airbags are spaced apart from each other in an inward-outward direction. A tether is connected to the first and second airbags to restrict relative movement between the airbags in the inward-outward direction in response to an occupant sinking in.

[0035] Clearly, in both of the aforementioned technologies, the airbag's placement is fixed, meaning the airbag can only deploy at specific locations.

[0036] Currently, to improve the passenger experience, the seat backrest angle in a vehicle can be made adjustable, or at least one seat in the vehicle can be made movable. This allows passengers to adjust the seat backrest angle and / or seat position according to their activity needs within the vehicle, providing sufficient space for their movement.

[0037] However, since the position of the airbag is fixed, the occupant may be moved out of the airbag's protection range after the seat moves and / or the angle of the seat back changes, causing the airbag to fail to provide effective protection for the occupant and reducing the effectiveness of the airbag in protecting the occupant.

[0038] To address the aforementioned technical problems, embodiments of this application provide a vehicle, such as... Figure 1 As shown, vehicle 100 may include airbag control system 110.

[0039] The airbag control system 110 corresponds to the seat 120 in the vehicle 100. Specifically, the airbag control system 110 can provide protection for the occupants in the seat 120.

[0040] It should be noted that seat 120 can be a movable seat or a fixed seat, and this application embodiment does not impose any special limitation on this. The movable seat can be installed on the inner surface of the vehicle compartment floor of vehicle 100, and the movable seat is configured to move in the length and / or width direction of vehicle 100. In addition, the backrest tilt angle of seat 120 is adjustable. The movable seat has a range of motion, the size of which can be determined based on information such as the size of the vehicle compartment and the seat layout.

[0041] The airbag control system 110 may include: an airbag assembly 111 and a controller 112.

[0042] The airbag assembly 111 may be disposed on the inner surface of the roof of the vehicle 100.

[0043] For example, when seat 120 is a movable seat, airbag assembly 111 is configured to be movable in the length and / or width directions of vehicle 100. The range of motion of airbag assembly 111 can be determined based on the range of motion of the movable seat.

[0044] For example, if seat 120 is a fixed seat, the specific installation position of airbag assembly 111 can be determined according to the installation position of seat 120.

[0045] In addition, the deployment angle of the baffle of the airbag assembly 111 is configured to be adjustable.

[0046] The controller 112 can be a device with processing capabilities, such as the central control unit in the vehicle 100, or it can be an independently set controller. This application embodiment does not make any special limitation on this.

[0047] The controller 112 can monitor adjustment trigger events of the airbag assembly 111, and, when an adjustment trigger event is detected, adjust the position of the airbag assembly 111 and / or the deployment angle of the baffle of the airbag assembly 111.

[0048] An adjustment trigger event for the airbag assembly 111 can refer to an event that triggers the adjustment of the position of the airbag assembly 111 and / or the deployment angle of the airbag baffle. By monitoring the adjustment trigger event of the airbag assembly 111, when the adjustment trigger event of the airbag assembly 111 is detected, the position of the airbag assembly 111 and / or the deployment angle of the airbag baffle can be adjusted to provide more effective protection for the occupant in the seat 120.

[0049] Obviously, since the controller 112 can monitor the adjustment trigger event of the airbag assembly 111, and when the controller 112 detects the adjustment trigger event of the airbag assembly 111, it can improve the effectiveness of the airbag assembly 111 in protecting the occupants by adjusting the position of the airbag assembly 111 and / or the deployment angle of the baffle of the airbag assembly 111, thereby ensuring the safety of the occupants.

[0050] Furthermore, by setting up the airbag assembly 111, and when an adjustment trigger event of the airbag assembly 111 is detected, the position of the airbag assembly 111 and / or the deployment angle of the baffle of the airbag assembly 111 can be adjusted, thereby improving the effectiveness of the airbag assembly 111 in protecting the occupants. This method is simple, easy to implement, and highly efficient.

[0051] The following provides an exemplary description of various specific implementation processes of the controller 112.

[0052] The first type, vehicle 100 includes movable seats, that is, in Figure 1 In this configuration, seat 120 is a movable seat. Adjustment trigger events include movement events of the movable seat. Based on this, the specific implementation process of controller 112 can be as follows: controller 112 can monitor movement events of the movable seat, and when a movement event of the movable seat is detected, adjust the position of airbag assembly 111 according to the travel information of the movable seat so that the movable seat is within the protection range of airbag assembly 111.

[0053] In the embodiments of this application, such as Figure 2 As shown, the movable seat (i.e., seat 120) may be an electrically powered movable seat. The movable seat may include a second slide rail 121, a first seat 122, and a second motor 123.

[0054] The second slide rail 121 is disposed on the inner surface of the bottom of the vehicle compartment of the vehicle 100. The first seat 122 is disposed on the second slide rail 121. The second motor 123 is connected to the first seat 122 and is also connected to the controller 112. Under the control of the controller 112, the second motor 123 can drive the first seat 122 to move on the second slide rail 121 to adjust the position of the first seat 122 on the second slide rail 121.

[0055] A movement control can be installed on the first seat 122. The third occupant on the first seat 122 can generate a movement command by operating on the movement control. The controller 112 can receive and respond to the movement command triggered by the third occupant on the first seat 122, and adjust the position of the first seat 122 on the second slide rail 121 by controlling the second motor 123.

[0056] Movement commands may include movement start commands and movement end commands. Operations applied to the movement control include a first operation and a second operation. The movement start command corresponds to the first operation on the movement control, and the movement end command corresponds to the second operation on the movement control.

[0057] Specifically, a third occupant on the first seat 122 can generate a movement start command through a first operation on the movement control. The controller 112 receives and responds to the movement start command triggered by the third occupant on the first seat 122, and drives the first seat 122 to start moving on the second slide rail 121 by controlling the second motor 123. Conversely, a third occupant on the first seat 122 can generate a movement stop command through a second operation on the movement control. The controller 112 receives and responds to the movement stop command triggered by the third occupant on the first seat 122, and stops the first seat 122 from moving on the second slide rail 121 by controlling the second motor 123.

[0058] The first and second operations applied to the mobile control can be click operations. Alternatively, the first operation applied to the mobile control can be a press operation, and the second operation applied to the mobile control can be a cancel press operation.

[0059] It should be noted that the above description of the first and second operations acting on the mobile control is merely exemplary and is not intended to limit the first and second operations in this application.

[0060] The movement control may include a first movement control and a second movement control, wherein the first movement control may be a control for the third occupant to control the first seat 122 to move forward, and the second movement control may be a control for the third occupant to control the first seat 122 to move backward.

[0061] For example, a third occupant on the first seat 122 generates a start-of-movement command by clicking the first movement control. The controller 112 receives and responds to the start-of-movement command triggered by the third occupant on the first seat 122, and drives the first seat 122 to start moving forward on the second slide rail 121 by controlling the second motor 123. When the first seat 122 moves to the expected position, the third occupant on the first seat 122 generates a stop-of-movement command by clicking the first movement control. The controller 112 receives and responds to the stop-of-movement command triggered by the third occupant on the first seat 122, and stops the first seat 122 from moving on the second slide rail 121 by controlling the second motor 123, thus realizing the adjustment of the position of the first seat 122.

[0062] For example, a third occupant on the first seat 122 generates a start-of-movement command by pressing the second movement control. The controller 112 receives and responds to the start-of-movement command triggered by the third occupant on the first seat 122, and drives the first seat 122 to begin moving backward on the second slide rail 121 by controlling the second motor 123. When the first seat 122 reaches the desired position, the third occupant on the first seat 122 generates a stop-of-movement command by canceling the pressing of the second movement control. The controller 112 receives and responds to the stop-of-movement command triggered by the third occupant on the first seat 122, and stops the first seat 122 from moving on the second slide rail 121 by controlling the second motor 123, thus realizing the adjustment of the position of the first seat 122.

[0063] In other embodiments, a backrest adjustment control may also be provided on the first seat 122, and a third occupant on the first seat 122 may adjust the tilt angle of the backrest of the first seat 122 by operating the backrest adjustment control.

[0064] It should be noted that, in Figure 2 In the diagram, the solid line indicates the position of the first seat 122, and the dashed line indicates the position of the first seat 122, representing the range of motion of the first seat 122. It should be noted that the range of motion of the first seat 122 can also be understood as the range of motion of the movable seat.

[0065] Based on this, the process by which controller 112 monitors the movement events of the movable seat can be described as follows:

[0066] The controller 112 can monitor movement events of the movable seat by detecting whether a movement command is received. Receiving a movement command indicates that a movement event has been detected, while not receiving a movement command indicates that no movement event has been detected.

[0067] Based on this, the travel information of the movable seat may include the movement displacement of the second motor 123 based on the movement command and the starting position of the movement of the second motor 123 based on the movement command.

[0068] As can be seen from the above, the movement command may include a movement start command and a movement end command. Therefore, the movement displacement of the second motor 123 based on the movement command can refer to the operating displacement of the second motor 123 between the movement start command and the movement end command. This operating displacement can be calculated based on the rotational speed and rotational time of the second motor 123 between the movement start command and the movement end command.

[0069] It should be noted that the movement displacement of the second motor 123 based on the movement command can be understood as the movement displacement of the movable seat, and the starting position of the movement of the second motor 123 based on the movement command can be understood as the starting position of the movement of the movable seat.

[0070] In addition, the airbag control system 110 may also include a first position sensor. The first position sensor is disposed on the first seat 122, and the first position sensor can monitor the position information of the first seat 122 and send the monitored position information of the first seat 122 to the controller 112.

[0071] Specifically, the monitoring here can be understood as collecting the position of the first seat 122 at a preset frequency and sending the collected position information of the first seat 122 to the controller 112. The specific value of the preset frequency can be determined according to design requirements.

[0072] Based on this, the travel information may also include the position information of the first seat 122 transmitted by the first position sensor. The position information of the first seat 122 here includes multiple positions of the first seat 122 acquired at a preset frequency.

[0073] In this way, after the first seat 122 moves, the position of the first seat 122 based on the movement command can be obtained from the position of the first seat 122 sent by the first position sensor, and the sum of the movement displacement of the second motor 123 based on the movement command and the movement start position of the second motor 123 based on the movement command can be calculated. The average value of the summation result and the position of the first seat 122 based on the movement command is determined as the final position of the first seat 122 based on the movement command.

[0074] It should be noted that the starting and ending positions of the first seat 122 based on the movement command can be understood as the starting and ending positions of the movable seat. The displacement of the first seat 122 based on the movement command can be understood as the displacement of the movable seat.

[0075] Obviously, by setting the first position sensor, when determining the ending position of the first seat 122 based on the movement command, the position of the first seat 122 collected by the first position sensor can be used to calibrate the ending position of the first seat 122 based on the movement command determined by the movement displacement of the second motor 123 based on the movement command and the movement start position of the second motor 123 based on the movement command, so as to improve the accuracy of determining the ending position of the first seat 122 based on the movement command.

[0076] In the embodiments of this application, such as Figure 3 As shown, the movable seat can also be a manually movable seat. The movable seat may include: a third slide rail 124 and a second seat 125.

[0077] The third slide rail 124 is provided on the inner surface of the bottom of the carriage of vehicle 100.

[0078] The second seat 125 is mounted on the third slide rail 124 and configured to move on the third slide rail 124 based on the operation of a fourth occupant on the second seat 125 to adjust the position of the second seat 125 on the third slide rail 124.

[0079] A control structure can be provided on the second seat 125. The fourth occupant on the second seat 125 can operate the control structure to lock or unlock the second seat 125, so that the fourth occupant can adjust the position of the second seat 125 on the third slide rail 124 by changing the state of the second seat 125 and in combination with the movement of the second seat 125 by the fourth occupant.

[0080] The locked state means that the second seat 125 is locked onto the third slide rail 124, meaning that the second seat 125 cannot move on the third slide rail 124. The unlocked state means that the second seat 125 can move on the third slide rail 124.

[0081] For example, a fourth occupant in the second seat 125 can operate the control structure to unlock the second seat 125. In this state, the fourth occupant can manually move the second seat 125, changing its position on the third slide rail 124. After the second seat 125 reaches the desired position, the fourth occupant can then operate the control structure to lock the second seat 125 to the desired position. It should be noted that the direction of movement of the second seat 125 is determined by the fourth occupant.

[0082] In other embodiments, a backrest adjustment control may also be provided on the second seat 125, and a fourth occupant on the second seat 125 may adjust the tilt angle of the backrest of the second seat 125 by operating the backrest adjustment control.

[0083] It should be noted that, in Figure 3 In the diagram, the solid line indicates the position of the second seat 125, and the dashed line indicates the position of the second seat 125, representing the range of motion of the second seat 125. It should be noted that the range of motion of the second seat 125 can also be understood as the range of motion of the movable seat.

[0084] Based on this, the airbag control system 110 may also include a second position sensor, which is disposed on the second seat 125. The second position sensor can monitor the position information of the second seat 125 and send the monitored position information of the second seat 125 to the controller 112.

[0085] Specifically, the monitoring here can be understood as collecting the position information of the second seat 125 at a preset frequency and sending the collected position information of the second seat 125 to the controller 112. It should be noted that the specific value of the preset frequency can be determined according to design requirements.

[0086] Based on this, the travel information of the movable seat may include the position information of the second seat 125 transmitted by the second position sensor. The position information of the second seat 125 here includes multiple positions of the second seat 125 acquired at a preset frequency.

[0087] In this way, after the second seat 125 moves, the position of the second seat 125 can be obtained from the position information of the second seat 125 sent by the second position sensor.

[0088] It should be noted that the moving end position of the second seat 125 can be understood as the moving end position of the movable seat.

[0089] Based on this, the process by which controller 112 listens for movement events of the movable seat can be described as follows:

[0090] The controller 112 determines whether the position of the second seat 125 has changed based on the position information of the second seat 125, and monitors movement events of the movable seat based on the determination result. A change in the position of the second seat 125 indicates that a movement event of the movable seat has been detected, while no change in the position of the second seat 125 indicates that no movement event of the movable seat has been detected.

[0091] Specifically, each time the controller 112 receives position information of the second seat 125 from a second position sensor, it compares the currently received position information of the second seat 125 with the previously received position information. If they are the same, it indicates that the position of the second seat 125 has not changed, that is, no movement event of the movable seat has been detected. If they are different, it indicates that the position of the second seat 125 has changed, that is, a movement event of the movable seat has been detected. Thus, when a movement event of the movable seat is detected, the controller 112 obtains the termination position of the movement of the second seat 125 from the multiple positions received, and adjusts the position of the airbag assembly according to the termination position of the movement of the second seat 125 (i.e., the first position).

[0092] Specifically, since the pattern of position change of the second seat 125 when the position of the second seat 125 changes is from no change to change and then back to no change, the termination position of the movement of the second seat 125 can be obtained based on this pattern.

[0093] It should be noted that the above description of the movable seat is merely exemplary and is not intended to limit the movable seat involved in this application. Furthermore, in Figures 1-3 In the middle, the airbag assembly 111 is in an undeployed state.

[0094] In this embodiment of the application, when a movement event of the movable seat is detected, the controller 112 adjusts the position of the airbag assembly 111 according to the travel information of the movable seat. The specific implementation process is as follows:

[0095] When the controller 112 detects a movement event, it determines a first position based on the travel information of the movable seat, and determines a second position based on the first position and a preset mapping relationship, and controls the airbag assembly 111 to move to the second position.

[0096] The first position is the termination position of the movable seat, and the second position is the termination position of the airbag assembly 111. The movable seat located at the first position is within the protection range of the airbag assembly 111 located at the second position. A preset mapping relationship is used to indicate the mapping relationship between the position of the movable seat and the position of the airbag assembly 111.

[0097] The travel information of the movable seat may include at least a portion of the following: the end position of the movable seat's movement, the start position of the movable seat's movement, and the displacement of the movable seat. The displacement of the movable seat may include the distance and direction of movement.

[0098] The first position can be determined as follows:

[0099] If the travel information of the movable seat includes the end position of the movable seat's movement, the end position of the movable seat's movement in the travel information is determined as the first position.

[0100] When the travel information of the movable seat includes the starting position and displacement of the movable seat, the sum of the starting position and displacement of the movable seat is determined as the first position.

[0101] Given that the travel information of the movable seat includes the moving end position, the moving start position, and the moving displacement of the movable seat, calculate the sum of the moving start position and the moving displacement of the movable seat, and determine the average of the sum and the moving end position of the movable seat as the first position.

[0102] The preset mapping relationship can be determined in the following way:

[0103] First, the length of the unit displacement interval of the movable seat can be determined based on the size of the protection range of the airbag assembly 111. The length of the unit displacement interval indicates the range of movement that the movable seat is allowed to make when the airbag assembly 111 is positioned in one location. In other words, when the position of the movable seat changes within the length of the unit displacement interval, the movable seat remains within the protection range of the airbag assembly 111.

[0104] Then, the range of motion of the movable seat can be divided into multiple movement intervals by the length of the unit displacement interval, wherein the length of each of the multiple movement intervals is the length of the unit displacement interval.

[0105] Next, multiple positions are determined based on multiple movement intervals, with each movement interval corresponding to one of the multiple positions. The position corresponding to each movement interval is the location of the airbag assembly 111. In other words, the movable seat located within the movement interval is within the protection range of the airbag assembly 111 located at the corresponding position.

[0106] Finally, the one-to-one correspondence between multiple movement intervals and multiple locations is determined as a preset mapping relationship.

[0107] Thus, the specific process of determining the second position based on the first position and the preset mapping relationship can be as follows:

[0108] Among multiple movement intervals, a first movement interval is determined, where the first movement interval is the movement interval to which the first position belongs. The position corresponding to the first movement interval is then determined as the second position.

[0109] Obviously, by setting a preset mapping relationship, the second position can be determined based on the first position and the preset mapping relationship. The implementation method is simple, easy to implement, and has high execution efficiency.

[0110] It should be noted that, in other embodiments, the starting position and the first position of the movable seat can be determined, in conjunction with multiple movement intervals, whether the starting position and the first position of the movable seat belong to the same movement interval. If they belong to the same movement interval, the position of the airbag assembly 111 is not adjusted. If they do not belong to the same movement interval, a first movement interval is determined among the multiple movement intervals, and the position corresponding to the first movement interval is determined as the second position.

[0111] By determining whether the starting position and the first position of the movable seat belong to the same movement interval, it can be determined whether the movable seat has moved out of the protection range of the airbag assembly 111. Furthermore, if they belong to the same movement interval, that is, if the movable seat has not moved out of the protection range of the airbag assembly 111, the position of the airbag assembly 111 is not adjusted, reducing energy consumption. If they do not belong to the same movement interval, that is, if the movable seat has moved out of the protection range of the airbag assembly 111, a first movement interval is determined among multiple movement intervals, and the position corresponding to the first movement interval is determined as the second position. The airbag assembly 111 is then moved to the second position, ensuring that the moved movable seat is within the protection range of the moved airbag assembly 111, thus providing effective protection for the occupant.

[0112] In this embodiment of the application, when a movement event of the movable seat is detected, the controller 112 adjusts the position of the airbag assembly 111 according to the travel information of the movable seat. The specific implementation process can also be as follows:

[0113] When the controller 112 detects a movement event, it controls the airbag assembly 111 to move according to the displacement of the movable seat, so that the movable seat is within the protection range of the airbag assembly 111. It should be noted that the movable seat is already within the protection range of the airbag assembly 111 before it moves.

[0114] It should be noted that the travel information of the movable seat includes the displacement of the movable seat.

[0115] Since the movable seat is within the protection range of the airbag assembly 111 before it moves, when a movement event is detected, by controlling the airbag assembly 111 to move according to the displacement of the movable seat, it can be ensured that the relative position between the airbag assembly 111 and the movable seat does not change. This ensures that the movable seat after movement is within the protection range of the airbag assembly 111 after movement, thereby providing effective protection for the occupant.

[0116] In summary, since vehicle 100 includes movable seats, occupants can adjust the position of the movable seats according to their own activity needs to adjust the activity space and provide space guarantee for occupants' activities within vehicle 100.

[0117] Furthermore, since the controller 112 can monitor the movement events of the movable seat, and when the controller 112 detects a movement event, it adjusts the position of the airbag assembly 111 according to the travel information of the movable seat, so that the movable seat is within the protection range of the airbag assembly 111. This enables the airbag assembly 111 to move with the movable seat, so that the airbag assembly 111 can still provide effective protection for the occupants in the movable seat after the movable seat moves, thus ensuring the safety of the occupants.

[0118] Furthermore, by setting up the airbag assembly 111 and adjusting its position based on the travel information of the movable seat when a movement event is detected, the movable seat can be kept within the protection range of the airbag assembly 111. This method is simple, easy to implement, and highly efficient.

[0119] Secondly, the vehicle 100 includes a third seat, which can be a seat in a movable seat or a seat in a fixed seat; this embodiment does not specifically limit this. The adjustment trigger event includes the backrest rotation event of the third seat.

[0120] Based on this, the airbag control system 110 may further include: a first angle sensor, which is disposed on the back of the third seat and is used to monitor the rotation event of the back of the third seat.

[0121] Based on this, the specific working process of controller 112 can be described as follows:

[0122] The controller 112 monitors backrest rotation events via a first angle sensor, and when a backrest rotation event is detected, determines a first angle based on the backrest rotation angle of the third seat monitored by the first angle sensor, and controls the baffle of the airbag assembly 111 to deploy at the first angle.

[0123] In this embodiment, the deployment angle of the airbag assembly 111 is determined by the deployment angle of its baffle. Furthermore, given a fixed deployment angle of the airbag assembly 111 and a zero or near-zero angle between the occupant in the third seat and the backrest of the third seat, the protective effect of the airbag assembly 111 on occupants with backrests at different tilt angles varies. Additionally, the occupant may change the tilt angle of the third seat backrest during seating. Therefore, to further provide effective protection for the occupant, a first angle sensor can be installed on the third seat to monitor backrest rotation events. Upon detecting a backrest rotation event, the sensor sends the backrest rotation angle to the controller 112. The controller 112 then determines the deployment angle (i.e., the first angle) of the baffle of the airbag assembly 111 based on the backrest rotation angle and controls the baffle of the airbag assembly 111 to deploy at the first angle, thereby adjusting the deployment angle of the airbag assembly 111 and further providing effective protection for the occupant.

[0124] The controller 112 determines the first angle based on the backrest rotation angle in the following manner:

[0125] A one-to-one correspondence between multiple tilt angles and multiple unfolding angles is predetermined, wherein the multiple tilt angles may include each tilt angle in the tilt angle range of the backrest of the third seat.

[0126] It should be noted that the first tilt angle is any one of multiple tilt angles. When the tilt angle of the backrest of the third seat is the first tilt angle, the airbag assembly 111 that deploys at the deployment angle corresponding to the first tilt angle can provide effective protection for the third seat.

[0127] Based on this, the sum of the initial tilt angle of the third seat's backrest rotation and the backrest rotation angle is determined as the third seat's rotation termination tilt angle. Based on the one-to-one correspondence between multiple tilt angles and multiple unfolding angles, the unfolding angle corresponding to the third seat's rotation termination tilt angle is determined as the first angle.

[0128] Thirdly, the vehicle 100 may include a fourth seat, which may be a seat in a movable seat or a seat in a fixed seat. This application embodiment does not make any special limitation in this regard.

[0129] The adjustment trigger events include posture change events of the first occupant in the fourth seat. The airbag control system 110 also includes: a second angle sensor and / or a first posture sensor, wherein:

[0130] The second angle sensor is installed on the back of the fourth seat. The second angle sensor can monitor the tilt angle of the back of the fourth seat and send the monitored tilt angle of the back of the fourth seat to the controller 112.

[0131] The backrest tilt angle can be the angle between the backrest and the first direction. The first direction is the direction perpendicular to the bottom of the carriage.

[0132] The monitoring here can be understood as collecting the backrest tilt angle of the fourth seat at a preset frequency and sending the collected backrest tilt angle of the fourth seat to the controller 112. It should be noted that the specific value of the preset frequency can be set according to design requirements.

[0133] The detected backrest tilt angle of the fourth seat can include multiple tilt angles of the fourth seat backrest collected by the second angle sensor at a preset frequency.

[0134] The first posture sensor is installed inside the vehicle to monitor the posture information of the first occupant and to send the monitored posture information of the first occupant to the controller 112.

[0135] Attitude information is used to indicate the tilt angle of the first occupant, which is the angle between the occupant's back and the first direction.

[0136] The monitoring here can be understood as collecting the posture information of the first occupant in the fourth seat at a preset frequency, and sending the collected posture information of the first occupant in the fourth seat to the controller 112. It should be noted that the specific value of the preset frequency can be determined according to design requirements.

[0137] The monitored posture information of the first occupant in the fourth seat may include multiple posture information of the first occupant in the fourth seat collected by the first posture sensor at a preset frequency.

[0138] The first pose sensor includes, but is not limited to, millimeter-wave radar and 3D camera, etc., and the embodiments of this application do not make any special limitations on it.

[0139] Based on this, the controller 112 can monitor posture change events by the backrest tilt angle of the fourth seat and / or the posture information of the first occupant, and when a posture change event is detected, adjust the deployment angle of the baffle of the airbag assembly 111 according to the backrest tilt angle of the fourth seat and / or the posture information of the first occupant.

[0140] Specifically, the controller 112 can determine whether to adjust the deployment angle of the airbag assembly 111's baffle based on the backrest tilt angle of the fourth seat and / or the posture information of the first occupant. When it is determined that the deployment angle of the airbag assembly 111's baffle should be adjusted, it determines that a posture change event has been detected, and determines a second angle based on the backrest tilt angle of the fourth seat and / or the posture information, and controls the airbag assembly 111's baffle to deploy at the second angle. The second angle is the deployment angle of the airbag assembly 111's baffle. When it is determined that the deployment angle of the airbag assembly 111's baffle should not be adjusted, it is determined that no posture change event has been detected.

[0141] The implementation process of controller 112 will be illustrated below using the following three methods.

[0142] In the first method, when the airbag control system 110 also includes a second angle sensor, each time the controller 112 receives a backrest tilt angle of the fourth seat, it compares the currently received backrest tilt angle with the previously received backrest tilt angle. If they are the same, it indicates that the backrest tilt angle of the fourth seat has not changed, that is, it is determined that the deployment angle of the airbag assembly 111's baffle will not be adjusted. If they are different, it indicates that the backrest tilt angle of the fourth seat has changed, that is, it is determined that the deployment angle of the airbag assembly 111's baffle will be adjusted. Furthermore, since the pattern of change in the backrest tilt angle when the fourth seat's backrest tilt angle changes is from constant tilt angle to changing tilt angle and then back to constant tilt angle. Therefore, when determining the deployment angle of the baffle of the airbag assembly 111, the rotation termination tilt angle of the backrest can be obtained according to this rule. Combining the one-to-one correspondence between the multiple tilt angles and multiple deployment angles mentioned above, the deployment angle corresponding to the rotation termination tilt angle of the backrest is determined as the second angle. The baffle of the airbag assembly 111 is then controlled to deploy at the second angle, thereby realizing the adjustment of the deployment angle of the dynamic airbag assembly 111 and providing effective protection for the occupants.

[0143] In the second approach, where the airbag control system 110 also includes a first posture sensor, when the controller 112 receives posture information, it compares the currently received posture information with the previously received posture information, i.e., it compares the two received occupant posture information. If they are the same, it indicates that the first occupant's posture has not changed, that is, it is determined that the deployment angle of the airbag assembly 111's baffle will not be adjusted. And, if they are different, it indicates that the first occupant's posture has changed, that is, it is determined that the deployment angle of the airbag assembly 111's baffle will be adjusted. Furthermore, since the pattern of change in the collected posture information when the first occupant's posture information changes is from constant to changing and then back to constant. Therefore, when determining the deployment angle of the baffle of the airbag assembly 111, the termination tilt angle of the first occupant can be obtained according to this rule. Combining the one-to-one correspondence between the multiple tilt angles and multiple deployment angles mentioned above, the deployment angle corresponding to the termination tilt angle of the first occupant is determined as the second angle. The baffle of the airbag assembly 111 is then controlled to deploy at the second angle, thereby realizing the adjustment of the deployment angle of the airbag assembly 111 and providing effective protection for the occupant.

[0144] Since the first occupant can lean against the backrest or be at an angle to the backrest when seated in the fourth seat, the deployment angle of the airbag assembly 111 can be adjusted according to the first occupant's posture information in the second way described above to provide better protection for the first occupant.

[0145] Thirdly, in the case where the airbag control system 110 also includes a second angle sensor and a first posture sensor, when the controller 112 receives backrest tilt angle and first occupant posture information, it compares the currently received backrest tilt angle with the previously received backrest tilt angle, and compares the currently received first occupant posture information with the previously received first occupant posture information. If neither the backrest tilt angle nor the first occupant posture information changes, it is determined that the deployment angle of the airbag assembly 111's baffle will not be adjusted. If either the backrest tilt angle or the first occupant posture information changes, it is determined that the deployment angle of the airbag assembly 111's baffle will be adjusted. Furthermore, according to the corresponding content in the first or second method described above, a second angle is determined, and the airbag assembly 111's baffle is controlled to deploy at the second angle, thereby adjusting the deployment angle of the airbag assembly 111 and providing effective protection for the first occupant. If both the backrest tilt angle and the posture information of the first occupant change, the deployment angle of the baffle of the airbag assembly 111 is determined to be adjusted. In addition, according to the relevant content in the second method above, a second angle is determined, and the baffle of the airbag assembly 111 is controlled to deploy at the second angle, thereby realizing the adjustment of the deployment angle of the airbag assembly 111.

[0146] Clearly, in the third approach, the deployment angle of the airbag assembly 111 is adjusted by combining the backrest tilt angle and the first occupant's posture information, thus providing better protection for the first occupant.

[0147] The fourth implementation differs from the first in that, in this fourth implementation, the adjustment trigger event also includes a posture change event of the second occupant on the movable seat. The airbag control system 110 also includes: a third angle sensor and / or a second pose sensor, wherein:

[0148] The third angle sensor is installed on the back of the movable seat. The third angle sensor can monitor the tilt angle of the back of the movable seat and send the monitored tilt angle of the back of the movable seat to the controller 112.

[0149] The second pose sensor is installed inside the vehicle 100. The second pose sensor can monitor the pose information of the second occupant and send the monitored pose information of the second occupant to the controller 112.

[0150] The second pose sensor includes, but is not limited to, millimeter-wave radar and 3D cameras, etc., and the embodiments of this application do not impose any special limitations on it.

[0151] The controller 112 is also used to monitor posture change events by means of the backrest tilt angle of the movable seat and / or the posture information of the second occupant, and, when a posture change event is detected, to adjust the deployment angle of the baffle of the airbag assembly 111 according to the backrest tilt angle of the movable seat and / or the posture information of the second occupant.

[0152] Since the deployment angle of the airbag assembly 111 is determined by the deployment angle of its baffle, and given that the airbag assembly 111 provides varying levels of protection to the second occupant in different postures at a fixed deployment angle, and considering that the second occupant can adjust their posture by adjusting the backrest angle of the movable seat and / or changing their seating position during seating, a third angle sensor and / or a second posture sensor can be installed to monitor posture change events based on the backrest angle of the movable seat and / or the second occupant's posture information. Upon detecting a posture change event, the deployment angle of the airbag assembly 111's baffle can be adjusted according to the backrest angle of the movable seat and / or the second occupant's posture information to provide more effective protection for the second occupant.

[0153] Specifically, the controller 112 can monitor attitude change events in the following way:

[0154] In the first scenario, where the airbag control system 110 also includes a third angle sensor, when the controller 112 receives a backrest tilt angle, it compares the currently received backrest tilt angle with the previously received backrest tilt angle. If they are the same, it indicates that the backrest tilt angle of the movable seat has not changed; that is, it is determined that no posture change event has been detected, and therefore, it is determined that the deployment angle of the airbag assembly 111's baffle will not be adjusted. If they are different, it indicates that the backrest tilt angle of the movable seat has changed; that is, it is determined that a posture change event has been detected, and therefore, it is determined that the deployment angle of the airbag assembly 111's baffle will be adjusted. Furthermore, since the pattern of change in the backrest tilt angle when the movable seat's backrest tilt angle changes is from a constant backrest tilt angle to a changing backrest tilt angle and then back to a constant backrest tilt angle. Therefore, when determining the deployment angle of the baffle of the airbag assembly 111, the rotation termination tilt angle of the backrest can be obtained according to this rule. Combining the one-to-one correspondence between the multiple tilt angles and multiple deployment angles mentioned above, the deployment angle corresponding to the rotation termination tilt angle of the backrest is determined as the third angle. The baffle of the airbag assembly 111 is then controlled to deploy at the third angle, thereby realizing the adjustment of the deployment angle of the airbag assembly 111 and further providing effective protection for the second occupant.

[0155] The second approach involves the airbag control system 110 also including a second posture sensor. When the controller 112 receives posture information, it compares the currently received posture information with the previously received posture information, i.e., comparing the two received posture information of the second occupant. If they are the same, it indicates that the second occupant's posture has not changed; that is, it is determined that no posture change event has been detected, and therefore, the deployment angle of the airbag assembly 111's baffle is not adjusted. Conversely, if they are different, it indicates that the second occupant's posture has changed; that is, a posture change event has been detected, and therefore, the deployment angle of the airbag assembly 111's baffle is adjusted. Furthermore, since the pattern of change in the collected posture information when the second occupant's posture information changes is from constant to changing and then back to constant. Therefore, when determining the deployment angle of the baffle of the airbag assembly 111, the termination tilt angle of the second occupant can be obtained from the posture information of the second occupant according to this rule. Based on the one-to-one correspondence between multiple tilt angles and multiple deployment angles mentioned above, the deployment angle corresponding to the termination tilt angle of the second occupant is determined as the third angle. The baffle of the airbag assembly 111 is then controlled to deploy at the third angle, thereby adjusting the deployment angle of the airbag assembly 111 and providing effective protection for the second occupant.

[0156] Since the second occupant can lean against the backrest or be at an angle to the backrest when seated in the movable seat, the deployment angle of the airbag assembly 111 can be adjusted according to the posture information of the second occupant in order to provide better protection for the second occupant.

[0157] Thirdly, in the case where the airbag control system 110 also includes a third angle sensor and a second posture sensor, when the controller 112 receives backrest tilt angle and second occupant posture information, it compares the currently received backrest tilt angle with the previously received backrest tilt angle and the currently received second occupant posture information with the previously received second occupant posture information. If neither the backrest tilt angle nor the second occupant posture information changes, it is determined that no posture change event has been detected, i.e., the deployment angle of the airbag assembly 111's baffle is not adjusted. If either the backrest tilt angle or the second occupant posture information changes, it is determined that a posture change event has been detected, i.e., the deployment angle of the airbag assembly 111's baffle is adjusted. Furthermore, according to the corresponding content in the first or second method described above, a third angle is determined, and the airbag assembly 111's baffle is controlled to deploy at the third angle, thereby adjusting the deployment angle of the airbag assembly 111 and further providing effective protection for the second occupant. If both the backrest tilt angle and the posture information of the second occupant change, then according to the relevant content in the second method above, the third angle is determined, and the baffle of the airbag assembly 111 is controlled to deploy at the third angle, thereby realizing the adjustment of the deployment angle of the airbag assembly 111.

[0158] Below, with Figure 2 For example, and in combination Figure 4 and Figure 5 An exemplary description is provided for the airbag assembly 111.

[0159] The airbag assembly 111 may include: a first slide rail 1111, an airbag 1112, and a first motor 1113. The airbag 1112 may include the storage structure 11121 and the airbag 11122 shown in the figure.

[0160] It should be noted that when the airbag 1112 is in the deployed state, that is, when the airbag assembly 111 is in the deployed state, such as Figure 4 As shown, airbag 11122 deploys in front of the occupant. When airbag 1112 is in the non-deployed state, i.e., when airbag assembly 111 is in the non-deployed state, as... Figure 2 As shown, the airbag 11122 is housed in the storage structure 11121.

[0161] The first slide rail 1111 is disposed on the inner surface of the roof of the vehicle 100. The airbag 1112 is disposed on the first slide rail 1111. The first motor 1113 is used to drive the airbag 1112 under the control of the controller 112, so that the airbag 1112 moves on the first slide rail 1111.

[0162] Based on the structure of the airbag assembly 111 described above, the specific way in which the controller 112 adjusts the position of the airbag assembly 111 can be, for example, by controlling the first motor 1113 to adjust the position of the airbag 1112.

[0163] It should be noted that the deployment angle of the baffle 1114 of the airbag assembly 111 can also be adjusted.

[0164] For example, Figure 6 This is an information flow diagram of an airbag control system provided in an embodiment of this application.

[0165] like Figure 6 As shown, the airbag control system may include a sensing module, a control module, and an execution module.

[0166] The perception module may include a collision sensor, a first position sensor, a third angle sensor, and a second pose sensor.

[0167] Collision sensors are installed on the vehicle to detect whether a collision has occurred and, upon detection, to send collision information to the controller. Other sensors have already been described above and will not be repeated here.

[0168] The control module may include a controller, which, in addition to performing the functions described above, is also used to receive and respond to collision information to deploy the airbag assembly so that the airbag assembly is in the deployed state.

[0169] The execution module may include airbag components, which have already been described above and will not be repeated here.

[0170] Below, in conjunction with Figure 6 An exemplary description is provided of the operation process of installing an airbag control system in a vehicle.

[0171] The first position sensor monitors the position of the movable seat. The monitored position is used as part of the movable seat's travel information. Furthermore, after the movable seat moves under the action of its second motor, the displacement of the second motor is used as part of the movable seat's travel information. In other words, the movable seat's travel information includes both the monitored position of the movable seat and the displacement of the second motor after the position of the movable seat changes.

[0172] The controller adjusts the position of the airbag assembly based on the travel information of the movable seat so that the movable seat is within the protection range of the airbag assembly.

[0173] The third angle sensor monitors the backrest tilt angle of the movable seat to obtain its position. The second pose sensor monitors the posture information of the second occupant on the movable seat to obtain their posture information.

[0174] The controller controls the deployment angle of the airbag assembly's flaps based on the backrest tilt angle of the movable seat and the posture information of the second occupant.

[0175] The collision sensor detects whether a collision has occurred and sends the collision information to the controller after a collision. The controller receives and responds to the collision information by deploying the airbag components to put the airbags into place.
