[0028] It should be noted that the modifications of "one" and "plurality" mentioned in the present invention are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise clearly indicated in the context, it should be understood as "one or more".
[0029] The names of the messages or information exchanged between multiple devices in the embodiments of the present invention are only used for illustrative purposes, and are not used to limit the scope of these messages or information.
[0030] Airbags can be installed in vehicles as a safety device. When a vehicle collides, the airbags are deployed to form a buffer between the occupants and the vehicle body, thereby reducing the collision force between the human body and the vehicle body and reducing the probability of occupant injury to a certain extent.
[0031] The airbag has a protection range. When the seat in the vehicle is within the protection range of the airbag, the airbag can provide protection for the occupant in the seat.
[0032] Typically, the position of an airbag is fixed, ie, the airbag can only be deployed at a fixed position.
[0033] For example, in a related art, a roof-mounted airbag is provided. The roof-mounted airbag includes an air-launching bracket, an air-launching airbag module, an airbag and a gas generator assembly. The air-launching bracket is fixedly connected to the roof of the vehicle, and the air-launching airbag module is mounted on the air-launching bracket. The airbag includes a driver's protection chamber, a middle protection chamber and a co-driver's protection chamber. The driver's protection chamber is connected to the middle protection chamber, and the middle protection chamber is connected to the co-driver's protection chamber. The airbag is accommodated in the roof-mounted airbag module. The gas generator assembly is arranged on the air-launching bracket and is connected to the airbag so that a large amount of gas generated is introduced into the airbag when it is triggered. In the roof-mounted airbag, by arranging the airbag at the front end of the roof and providing frontal protection for the driver and the co-driver at the same time, after the airbag is deployed, the airbag forms a convex structure between the driver and the co-driver to prevent a collision between the driver and the co-driver, thereby providing more complete protection for the front passengers.
[0034] In another related art, a occupant restraint system mounted on a vehicle roof is provided, the system being a restraint system for protecting a first occupant and a second occupant of a vehicle having a roof and a passenger compartment, the passenger compartment having a first seat and a second seat for carrying the first occupant and the second occupant. The restraint system includes a first airbag and a second airbag mounted to the vehicle roof. Each of the first airbag and the second airbag has a stored state and can be inflated to a deployed state aligned with the corresponding first occupant and the second occupant. The deployed first airbag and the second airbag are spaced apart from each other in the in-out direction. A tether is connected to the first airbag and the second airbag for limiting the relative movement between the airbags in the in-out direction in response to the occupant falling into the airbag.
[0035] Obviously, in the above two related technologies, the setting position of the airbag is fixed, that is, the airbag can only be deployed at a specific position.
[0036] At present, in order to improve the riding experience of passengers, the inclination angle of the seat back in the vehicle can be set to be adjustable, or at least one seat in the vehicle can be set to be movable. In this way, the passenger can adjust the inclination angle of the seat back and / or the position of the seat according to the activity requirements in the vehicle, so as to provide space guarantee for the activities of the passenger in the vehicle.
[0037] However, since the position of the airbag is fixed, when the seat moves and / or the reclining angle of the seat back changes, the occupant in the seat may deviate from the protection range of the airbag, resulting in the airbag being unable to provide effective protection for the occupant, thereby reducing the effectiveness of the airbag in protecting the occupant.
[0038] In order to solve the above technical problems, the present application embodiment provides a vehicle, such as Figure 1 As shown, vehicle 100 may include an 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 occupant on the seat 120 .
[0040] It should be noted that the seat 120 can be a movable seat or a fixed seat, and the embodiment of the present application does not specifically limit this. The movable seat can be arranged on the inner surface of the bottom of the vehicle 100, and the movable seat is configured to move in the length direction and / or width direction of the vehicle 100. In addition, the backrest inclination angle of the seat 120 can be adjusted. The movable seat has a range of movement, and the size of the range of movement can be determined according to information such as the size of the vehicle's compartment and the seat layout.
[0041] The airbag control system 110 may include: an airbag assembly 111 and a controller 112.
[0042] The airbag module 111 may be disposed on an inner surface of a roof of a cabin of the vehicle 100 .
[0043] For example, in the case where the seat 120 is a movable seat, the airbag assembly 111 is configured to be movable in the length direction and / or width direction of the vehicle 100. The movement range of the airbag assembly 111 may be determined according to the movement range of the movable seat.
[0044] For another example, when the seat 120 is a fixed seat, the specific installation position of the airbag assembly 111 can be determined according to the installation position of the seat 120 .
[0045] In addition, the deployment angle of the baffle of the airbag module 111 is configured to be adjustable.
[0046] The controller 112 may be, for example, a device with processing capabilities such as a central control in the vehicle 100 , or may be an independently arranged controller, which is not particularly limited in the embodiments of the present application.
[0047] The controller 112 may monitor an adjustment triggering event of the airbag assembly 111 , and, when an adjustment triggering 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] The adjustment triggering event of the airbag assembly 111 may refer to an event that triggers the adjustment of the position of the airbag assembly 111 and / or the deployment angle of the baffle. By monitoring the adjustment triggering event of the airbag assembly 111, when the adjustment triggering event of the airbag assembly 111 is monitored, the position of the airbag assembly 111 and / or the deployment angle of the baffle of the airbag assembly 111 can be adjusted to provide more effective protection for the occupant on the seat 120.
[0049] Obviously, since the controller 112 can monitor the adjustment triggering event of the airbag assembly 111, and when the controller 112 monitors the adjustment triggering event of the airbag assembly 111, the effectiveness of the airbag assembly 111 in protecting the occupants can be improved 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 providing an airbag assembly 111 and, when an adjustment triggering 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 is simple to implement and has high execution efficiency.
[0051] Below, various specific implementation processes of the controller 112 are exemplified.
[0052] First, the vehicle 100 includes movable seats, that is, Figure 1 In the embodiment, the seat 120 is a movable seat. The adjustment trigger event includes a movement event of the movable seat. Based on this, the specific implementation process of the controller 112 may be: the controller 112 may monitor the movement event of the movable seat, and, when the movement event of the movable seat is monitored, adjust 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.
[0053] In the embodiments of the present application, Figure 2 As shown, the movable seat (i.e., seat 120) may be an electrically 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, and the second motor 123 is connected to the first seat 122. The second motor 123 is also connected to the controller 112. The second motor 123 can drive the first seat 122 to move on the second slide rail 121 under the control of the controller 112 to adjust the position of the first seat 122 on the second slide rail 121.
[0055] A movement control may be provided on the first seat 122. The third passenger on the first seat 122 may generate a movement instruction by operating on the movement control, and the controller 112 may receive and respond to the movement instruction triggered by the third passenger 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] The movement instruction may include a movement start instruction and a movement end instruction. The operation acting on the mobile control includes a first operation acting on the mobile control and a second operation acting on the mobile control. Among them, the movement start instruction corresponds to the first operation acting on the mobile control, and the movement end instruction corresponds to the second operation acting on the mobile control.
[0057] Specifically, the third passenger on the first seat 122 can generate a movement start instruction by acting on the movement control through a first operation, and the controller 112 receives and responds to the movement start instruction triggered by the third passenger 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. Also, the third passenger on the first seat 122 can generate a movement termination instruction by acting on the movement control through a second operation, and the controller 112 receives and responds to the movement termination instruction triggered by the third passenger 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 operation and the second operation acting on the mobile control may be a click operation. Alternatively, the first operation acting on the mobile control may be a press operation, and the second operation acting on the mobile control may be a cancel press operation.
[0059] It should be noted that the above description of the first operation and the second operation acting on the mobile control is only exemplary and is not used to limit the first operation and the second operation 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 passenger to control the first seat 122 to move forward, and the second movement control may be a control for the third passenger to control the first seat 122 to move backward.
[0061] For example, the third passenger on the first seat 122 generates a movement start instruction by clicking the first movement control, and the controller 112 receives and responds to the movement start instruction triggered by the third passenger 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 passenger on the first seat 122 generates a movement termination instruction by clicking the first movement control, and the controller 112 receives and responds to the movement termination instruction triggered by the third passenger on the first seat 122, and controls the second motor 123 to stop the first seat 122 from moving on the second slide rail 121, thereby adjusting the position of the first seat 122.
[0062] For another example, the third passenger on the first seat 122 generates a movement start instruction by pressing the second movement control, and the controller 112 receives and responds to the movement start instruction triggered by the third passenger on the first seat 122, and drives the first seat 122 to start moving backward on the second slide rail 121 by controlling the second motor 123. When the first seat 122 moves to the expected position, the third passenger on the first seat 122 generates a movement termination instruction by canceling the pressing of the second movement control, and the controller 112 receives and responds to the movement termination instruction triggered by the third passenger 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, thereby adjusting the position of the first seat 122.
[0063] In other embodiments, a backrest adjustment control may be further provided on the first seat 122 , and the third passenger 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 figure, the position of the first seat 122 indicated by the solid line and the position of the first seat 122 indicated by the dotted line are the moving range of the first seat 122. It should be noted that the moving range of the first seat 122 can also be understood as the moving range of the movable seat.
[0065] On this basis, the process of the controller 112 monitoring the movement event of the movable seat can be as follows:
[0066] The controller 112 can monitor the movement event of the movable seat by detecting whether a movement instruction is received, wherein the reception of the movement instruction indicates that a movement event is monitored, and the failure to receive the movement instruction indicates that a movement event is not monitored.
[0067] On this basis, the travel information of the movable seat may include the movement displacement of the second motor 123 based on the movement instruction and the movement starting position of the second motor 123 based on the movement instruction.
[0068] As can be seen from the above, the movement instruction may include a movement start instruction and a movement end instruction. Therefore, the movement displacement of the second motor 123 based on the movement instruction may refer to the operation displacement of the second motor 123 between the movement start instruction and the movement end instruction. The operation displacement may be calculated based on the rotation speed and rotation time of the second motor 123 between the movement start instruction and the movement end instruction.
[0069] It should be noted that the movement displacement of the second motor 123 based on the movement instruction can be understood as the movement displacement of the movable seat, and the movement starting position of the second motor 123 based on the movement instruction can be understood as the movement starting position of the movable seat.
[0070] On this basis, the airbag control system 110 may further include a first position sensor. The first position sensor is disposed on the first seat 122 , and the first position sensor may 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 sent by the first position sensor. The position information of the first seat 122 here includes multiple positions of the first seat 122 collected according to a preset frequency.
[0073] In this way, after the first seat 122 moves, the movement end position of the first seat 122 based on the movement instruction can be obtained from the position of the first seat 122 sent by the first position sensor, and the movement displacement of the second motor 123 based on the movement instruction and the movement starting position of the second motor 123 based on the movement instruction are calculated, and the sum of the sum result and the movement end position of the first seat 122 based on the movement instruction is determined as the final movement end position of the first seat 122 based on the movement instruction.
[0074] It should be noted that the movement start position and movement end position of the first seat 122 based on the movement instruction can be understood as the movement start position and movement end position of the movable seat. The movement displacement of the first seat 122 based on the movement instruction can be understood as the movement displacement of the movable seat.
[0075] Obviously, by setting the first position sensor, when determining the movement end position of the first seat 122 based on the movement instruction, the position of the first seat 122 collected by the first position sensor can be calibrated with the movement end position of the first seat 122 based on the movement instruction determined by the movement displacement of the second motor 123 based on the movement instruction and the movement starting position of the second motor 123 based on the movement instruction, so as to improve the accuracy of determining the movement end position of the first seat 122 based on the movement instruction.
[0076] In the embodiments of the present application, Figure 3 As shown, the movable seat can also be a manually movable seat. The movable seat can 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 vehicle compartment of the vehicle 100 .
[0078] The second seat 125 is disposed on the third slide rail 124 and is configured to move on the third slide rail 124 based on an operation of the fourth occupant on the second seat 125 to adjust a position of the second seat 125 on the third slide rail 124 .
[0079] A control structure may be provided on the second seat 125. The fourth passenger on the second seat 125 may operate the control structure to lock or unlock the second seat 125, so that the fourth passenger 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 combining the movement of the second seat 125 by the fourth passenger.
[0080] The locked state means that the second seat 125 is locked to the third slide rail 124 , that is, 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, the fourth passenger on the second seat 125 can operate the control structure to put the second seat 125 in an unlocked state. At this time, the fourth passenger on the second seat 125 manually moves the second seat 125 to change the position of the second seat 125 on the third slide rail 124. After the second seat 125 moves to the expected position, the fourth passenger on the second seat 125 can operate the control structure to put the second seat 125 in a locked state, thereby locking the second seat 125 to the expected position. It should be noted that the moving direction of the second seat 125 is determined by the fourth passenger.
[0082] In other embodiments, a backrest adjustment control may be further provided on the second seat 125 , and the fourth passenger 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 figure, the position of the second seat 125 indicated by the solid line and the position of the second seat 125 indicated by the dotted line are the moving range of the second seat 125. It should be noted that the moving range of the second seat 125 can also be understood as the moving range of the movable seat.
[0084] On this basis, the airbag control system 110 may further include a second position sensor, which is disposed on the second seat 125 . The second position sensor may 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 frequency can be preset 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 sent by the second position sensor. The position information of the second seat 125 here includes multiple positions of the second seat 125 collected according to a preset frequency.
[0087] In this way, after the second seat 125 moves, the movement termination 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 movement end position of the second seat 125 can be understood as the movement end position of the movable seat.
[0089] On this basis, the process of the controller 112 monitoring the movement event of the movable seat can be as follows:
[0090] The controller 112 determines whether the position of the second seat 125 has changed according to the position information of the second seat 125, and monitors the movement event of the movable seat based on the determination result. Wherein, if the position of the second seat 125 has changed, it indicates that the movement event of the movable seat has been monitored, and if the position of the second seat 125 has not changed, it indicates that the movement event of the movable seat has not been monitored.
[0091] Specifically, each time the controller 112 receives position information of the second seat 125 sent by the second position sensor, the controller 112 compares the currently received position information of the second seat 125 with the position information of the second seat 125 received the previous time. When the two are the same, it indicates that the position of the second seat 125 has not changed, that is, the movement event of the movable seat has not been monitored. When the two are different, it indicates that the position of the second seat 125 has changed, that is, the movement event of the movable seat has been monitored. In this way, when the movement event of the movable seat is monitored, the movement end position of the second seat 125 is obtained from the multiple positions of the received second seat 125, so as to adjust the movement position of the airbag assembly according to the movement end position of the second seat 125 (i.e., the first position).
[0092] Specifically, when the position of the second seat 125 changes, the collected change pattern of the position of the second seat 125 is from no change to change and then to no change. Therefore, the movement end position 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 only exemplary and is not intended to limit the movable seat involved in this application. Figure 1 to Figure 3 In the embodiment, the airbag assembly 111 is in a non-deployed state.
[0094] In the embodiment of the present 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 be as follows:
[0095] When detecting a movement event, the controller 112 determines a first position according to the travel information of the movable seat, determines a second position according to 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 end position of the movable seat, and the second position is the end position of the airbag assembly 111. The movable seat at the first position is within the protection range of the airbag assembly 111 at the second position. The 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 part of the information of the movable seat's end position, the movable seat's start position, the movable seat's displacement, etc. The movable seat's displacement may include the moving distance and the moving direction.
[0098] The first position may be determined as follows:
[0099] In a case where the travel information of the movable seat includes a movement end position of the movable seat, the movement end position of the movable seat in the travel information is determined as the first position.
[0100] In the case where the travel information of the movable seat includes the movement start position of the movable seat and the movement displacement of the movable seat, the sum of the movement start position of the movable seat and the movement displacement of the movable seat is determined as the first position.
[0101] When the travel information of the movable seat includes the moving end position of the movable seat, the moving starting position of the movable seat, and the moving displacement of the movable seat, the sum of the moving starting position of the movable seat and the moving displacement of the movable seat is calculated, and the average value of the sum and the moving end position of the movable seat is determined as the first position.
[0102] The method for determining the preset mapping relationship may be, for example, as follows:
[0103] First, the length of the unit displacement interval of the movable seat can be determined according to the size of the protection range of the airbag assembly 111. The length of the unit displacement interval indicates the range within which the movable seat is allowed to move when the airbag assembly 111 is set at one position, that is, when the position of the movable seat changes within the length of the unit displacement interval, the movable seat is always within the protection range of the airbag assembly 1111.
[0104] Then, the moving range of the movable seat can be divided into a plurality of moving intervals according to the length of the unit displacement interval, wherein the length of each of the plurality of moving intervals is the length of the unit displacement interval.
[0105] Then, multiple positions are determined according to the multiple movement intervals, wherein the multiple movement intervals correspond to the multiple positions one by one, and the position corresponding to each movement interval is the position of the airbag assembly 111. In other words, the movable seat located in the movement interval is within the protection range of the airbag assembly 111 set at the corresponding position.
[0106] Finally, the one-to-one correspondence between the multiple moving intervals and the multiple positions is determined as a preset mapping relationship.
[0107] Thus, according to the first position and the preset mapping relationship, the specific process of determining the second position can be as follows:
[0108] A first moving interval is determined from among the plurality of moving intervals, wherein the first moving interval is a moving interval to which the first position belongs among the plurality of moving intervals, and a position corresponding to the first moving interval is determined as a second position.
[0109] Obviously, by setting a preset mapping relationship, the second position can be determined according to the first position and the preset mapping relationship, and the implementation method is simple and easy with high execution efficiency.
[0110] It should be noted that, in other embodiments, it is also possible to determine whether the movable seat's moving starting position and the first position belong to the same moving interval based on the movable seat's moving starting position and the first position, and in combination with multiple moving intervals. When they belong to the same moving interval, the position of the airbag assembly 111 is not adjusted. When they do not belong to the same moving interval, the first moving interval is determined from the multiple moving intervals, and the position corresponding to the first moving interval is determined as the second position.
[0111] By judging whether the movable seat's starting position and the first position belong to the same moving interval, it can be determined whether the movable seat has moved out of the protection range of the airbag assembly 111. Also, when they belong to the same moving interval, that is, when 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, thereby reducing energy consumption. When they do not belong to the same moving interval, that is, when the movable seat has moved out of the protection range of the airbag assembly 111, the first moving interval is determined among a plurality of moving intervals, and the position corresponding to the first moving interval is determined as the second position, so that the airbag assembly 111 is controlled to move to the second position, so that the movable seat after the move is located in the protection range of the airbag assembly 111 after the move, thereby providing effective protection for the occupants.
[0112] In the embodiment of the present 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, and 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 movement 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 before the movable seat moves, the movable seat is within the protection range of the airbag assembly 111.
[0114] It should be noted that the travel information of the movable seat includes the movement displacement of the movable seat.
[0115] Because the movable seat is located within the protection range of the airbag assembly 111 before the movable seat moves, when a movement event is monitored, the airbag assembly 111 is controlled to move according to the movement displacement of the movable seat, thereby ensuring that the relative position between the airbag assembly 111 and the movable seat does not change, thereby ensuring that the movable seat after movement is within the protection range of the airbag assembly 111 after movement, thereby providing effective protection for the occupants.
[0116] In summary, since the vehicle 100 includes movable seats, the occupants can adjust the positions of the movable seats based on their own activity needs to adjust the activity space, thereby providing space guarantee for the occupants' activities in the vehicle 100 .
[0117] Furthermore, since the controller 112 can monitor the movement events of the movable seat, and when the controller 112 detects the movement events, it adjusts the position of the airbag assembly 111 according to the travel information of the movable seat, so that the movable seat can be within the protection range of the airbag assembly 111, and the airbag assembly 111 can move along with the movement of the movable seat, so that after the movable seat moves, the airbag assembly 111 can still provide effective protection for the occupants on the movable seat, thereby ensuring the safety of the occupants.
[0118] Furthermore, by setting up the airbag assembly 111 and adjusting the position of the airbag assembly 111 according to the travel information of the movable seat when a movement event is monitored, the movable seat can be within the protection range of the airbag assembly 111. The implementation method is simple, easy to execute and efficient.
[0119] Second, the vehicle 100 includes a third seat, which may be a seat in a movable seat or a seat in a fixed seat, which is not specifically limited in the present embodiment. The adjustment trigger event includes a 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 backrest of the third seat and is used to monitor a backrest rotation event of the third seat.
[0121] Based on this, the specific working process of the controller 112 can be as follows:
[0122] The controller 112 monitors the backrest rotation event through the first angle sensor, and when the backrest rotation event is detected, determines the first angle according to 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 the embodiment of the present application, the deployment angle of the airbag assembly 111 is determined by the deployment angle of the baffle of the airbag assembly 111. In addition, when the deployment angle of the airbag assembly 111 is constant and the angle between the occupant on the third seat and the backrest of the third seat is zero or approximately zero, the airbag assembly 111 has different protective effects on the occupants on the third seat with backrests of different tilt angles. In addition, the occupant may change the tilt angle of the backrest of the third seat during the ride. Therefore, in order to further provide effective protection for the occupant, a first angle sensor may be provided on the third seat to monitor the backrest rotation event of the third seat through the first angle sensor, and when the backrest rotation event is detected, the backrest rotation angle is sent to the controller 112, so that the controller 112 determines the deployment angle (i.e., the first angle) of the baffle of the airbag assembly 111 according to the backrest rotation angle, and controls the baffle of the airbag assembly 111 to be deployed at the first angle, thereby realizing the adjustment of the deployment angle of the entire airbag assembly 111, thereby further providing effective protection for the occupant.
[0124] The controller 112 may determine the first angle according to the rotation angle of the backrest as follows:
[0125] A one-to-one correspondence between a plurality of tilting angles and a plurality of unfolding angles is predetermined, wherein the plurality of tilting angles may include each tilting angle in a tilting angle range of the backrest of the third seat.
[0126] It should be noted that the first tilt angle is any one of a plurality of tilt angles, and when the tilt angle of the backrest of the third seat is the first tilt angle, the airbag assembly 111 deployed 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 backrest rotation of the third seat and the backrest rotation angle is determined as the rotation termination tilt angle of the third seat. Based on the one-to-one correspondence between multiple tilt angles and multiple deployment angles, the deployment angle corresponding to the rotation termination tilt angle of the third seat is determined as the first angle.
[0128] Thirdly, the vehicle 100 may include a fourth seat, and the fourth seat may be a seat in the movable seats or a seat in the fixed seats, which is not particularly limited in the embodiment of the present application.
[0129] The adjustment triggering event includes a posture change event of the first occupant on the fourth seat. The airbag control system 110 further includes: a second angle sensor and / or a first posture sensor, wherein:
[0130] The second angle sensor is disposed on the backrest of the fourth seat. The second angle sensor can monitor the tilting angle of the backrest of the fourth seat and send the monitored tilting angle of the backrest of the fourth seat to the controller 112 .
[0131] The backrest inclination angle may be the angle between the backrest and a first direction. The first direction is a direction perpendicular to the bottom surface of the vehicle compartment.
[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 frequency can be preset according to design requirements.
[0133] The monitored tilt angle of the backrest of the fourth seat may include a plurality of tilt angles of the backrest of the fourth seat acquired by the second angle sensor at a preset frequency.
[0134] The first posture sensor is disposed inside the vehicle, and is used to monitor the posture information of the first occupant, and send the monitored posture information of the first occupant to the controller 112 .
[0135] The posture information is used to indicate a tilt angle of the first occupant, where the tilt angle of the first occupant is an 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 on the fourth seat at a preset frequency, and sending the collected posture information of the first occupant on the fourth seat to the controller 112. It should be noted that the specific value of the frequency can be preset according to design requirements.
[0137] The monitored posture information of the first occupant on the fourth seat may include multiple posture information of the first occupant on the fourth seat collected by the first posture sensor according to a preset frequency.
[0138] The first posture sensor includes but is not limited to millimeter wave radar and 3D camera, etc., and the embodiment of the present application does not make any special limitation on this.
[0139] Based on this, the controller 112 can monitor posture change events through 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 may determine whether to 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 passenger, and, when determining to adjust the deployment angle of the baffle of the airbag assembly 111, determine that a posture change event is detected, and determine a second angle according to the backrest tilt angle and / or posture information of the fourth seat, and control the baffle of the airbag assembly 111 to deploy at the second angle. The second angle is the deployment angle of the baffle of the airbag assembly 111. When determining not to adjust the deployment angle of the baffle of the airbag assembly 111, determine that no posture change event is detected.
[0141] The implementation process of the controller 112 is exemplified below from the following three methods.
[0142] In the first way, 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, the backrest tilt angle currently received is compared with the backrest tilt angle received last time. If the two are the same, it indicates that the backrest tilt angle of the fourth seat has not changed, that is, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. If the two are not the same, it indicates that the backrest tilt angle of the fourth seat has changed, that is, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111. And, since the backrest tilt angle of the fourth seat changes, the change rule of the collected backrest tilt angle is from unchanged tilt angle to changed tilt angle and then unchanged tilt angle. Therefore, when determining to adjust 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, and combined with the one-to-one correspondence between the multiple tilt angles and the multiple deployment angles mentioned above, the deployment angle corresponding to the rotation termination tilt angle of the backrest is determined as the second angle, 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 dynamic airbag assembly 111, thereby providing effective protection for the occupants.
[0143] The second method is that when the airbag control system 110 also includes a first posture sensor, each time the controller 112 receives a posture information, the currently received posture information is compared with the posture information received last time, that is, the posture information of the occupants received twice is compared. If the two are the same, it indicates that the posture of the first occupant has not changed, that is, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. And, if the two are not the same, it indicates that the posture of the first occupant has changed, that is, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111. And, because the posture information of the first occupant changes, the change pattern of the collected posture information is from unchanged to changed and then unchanged. Therefore, when determining to adjust the deployment angle of the baffle of the airbag assembly 111, the terminal tilt angle of the first occupant can be obtained according to this rule, and combined with the one-to-one correspondence between the multiple tilt angles and the multiple deployment angles mentioned above, the deployment angle corresponding to the terminal tilt angle of the first occupant is determined as the second angle, and the baffle of the airbag assembly 111 is controlled to deploy at the second angle, thereby achieving the adjustment of the deployment angle of the airbag assembly 111, thereby providing effective protection for the occupants.
[0144] Because the first occupant can lean against the backrest or form a certain angle with the backrest when sitting on the fourth seat, in order to further provide better protection for the first occupant, the deployment angle of the baffle of the airbag assembly 111 can be adjusted according to the posture information of the first occupant through the second method mentioned above, so as to provide more effective protection for the first occupant.
[0145] The third method is that when the airbag control system 110 further includes a second angle sensor and a first posture sensor, each time the controller 112 receives a backrest tilt angle and the posture information of the first occupant, the currently received backrest tilt angle is compared with the previously received backrest tilt angle, and the currently received first occupant posture information is compared with the previously received first occupant posture information. If the backrest tilt angle and the posture information of the first occupant do not change, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. If one of the backrest tilt angle and the posture information of the first occupant changes, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111, and, according to the corresponding content in the first or second method above, determine the second angle, and control the baffle of the airbag assembly 111 to deploy at the second angle, so as to achieve the adjustment of the deployment angle of the airbag assembly 111, thereby providing effective protection for the first occupant. If the backrest inclination angle and the posture information of the first passenger change, the deployment angle of the baffle of the airbag assembly 111 is adjusted, and, based on the relevant content in the second method mentioned above, the second angle is determined, and the baffle of the airbag assembly 111 is controlled to be deployed at the second angle, thereby achieving the adjustment of the deployment angle of the airbag assembly 111.
[0146] Obviously, in the third mode, the deployment angle of the airbag assembly 111 is adjusted by combining the backrest tilt angle and the posture information of the first occupant, so as to provide better protection for the first occupant.
[0147] Fourth, the fourth is different from the first in that: in the 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 posture sensor, wherein:
[0148] The third angle sensor is disposed on the backrest of the movable seat, and the third angle sensor can monitor the tilting angle of the backrest of the movable seat, and send the monitored tilting angle of the backrest of the movable seat to the controller 112 .
[0149] The second posture sensor is disposed inside the vehicle 100 , and the second posture sensor can monitor posture information of the second occupant, and send the monitored posture information of the second occupant to the controller 112 .
[0150] The second posture sensor includes but is not limited to millimeter wave radar and 3D camera, etc., and the embodiment of the present application does not make any special limitation on this.
[0151] The controller 112 is also used to monitor posture change events through the backrest tilt angle of the movable seat and / or the posture information of the second occupant, and, when a posture change event is monitored, 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 the baffle of the airbag assembly 111. And since the protection effect of the airbag assembly 111 on the second occupant in different postures is different when the deployment angle of the airbag assembly 111 is constant. In addition, the second occupant can change his posture by adjusting the backrest tilt angle of the movable seat and / or changing his sitting posture during riding. Therefore, in order to further provide effective protection for the second occupant, a third angle sensor and / or a second posture sensor can be set to monitor the posture change event through the backrest tilt angle of the movable seat and / or the posture information of the second occupant monitored by the third angle sensor and / or the second posture sensor. When a posture change event is detected, the deployment angle of the baffle of the airbag assembly 111 is adjusted according to the backrest tilt angle of the movable seat and / or the posture information of the second occupant to provide more effective protection for the second occupant.
[0153] Specifically, the specific implementation method of the controller 112 monitoring the posture change event can be as follows:
[0154] The first one is that when the airbag control system 110 also includes a third angle sensor, the controller 112 compares the currently received backrest tilt angle with the previously received backrest tilt angle each time a backrest tilt angle is received. If the two 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, that is, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. If the two are not the same, 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, that is, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111. And, because when the backrest tilt angle of the movable seat changes, the change pattern of the collected backrest tilt angle is from the backrest tilt angle being unchanged to the backrest tilt angle changing and then to the backrest tilt angle being unchanged. Therefore, when determining to adjust 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, and combined with the one-to-one correspondence between the multiple tilt angles and the multiple deployment angles mentioned above, the deployment angle corresponding to the rotation termination tilt angle of the backrest is determined as the third angle, and the baffle of the airbag assembly 111 is controlled to deploy at the third angle, thereby achieving the adjustment of the deployment angle of the airbag assembly 111, thereby further providing effective protection for the second occupant.
[0155] The second type is that when the airbag control system 110 also includes a second posture sensor, each time the controller 112 receives a posture information, the currently received posture information is compared with the posture information received last time, that is, the posture information of the second occupant received twice is compared. If the two are the same, it indicates that the posture of the second occupant has not changed, that is, it is determined that no posture change event is detected, that is, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. And, if the two are not the same, it indicates that the posture of the second occupant has changed, that is, a posture change event is detected, that is, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111. And, because when the posture information of the second occupant changes, the change pattern of the collected posture information is from unchanged to changed and then unchanged. Therefore, when determining to adjust the deployment angle of the baffle of the airbag assembly 111, the terminal tilt angle of the second occupant can be obtained from the posture information of the second occupant according to this rule, and according to the one-to-one correspondence between the multiple tilt angles and the multiple deployment angles in the above text, the deployment angle corresponding to the terminal tilt angle of the second occupant is determined as the third angle, and the baffle of the airbag assembly 111 is controlled to deploy at the third angle, thereby achieving the adjustment of the deployment angle of the airbag assembly 111, thereby further providing effective protection for the second occupant.
[0156] Since the second occupant can lean against the backrest or form a certain angle with the backrest when sitting on the movable seat, in order to further provide better protection for the second occupant, the deployment angle of the baffle of the airbag assembly 111 can be adjusted according to the posture information of the second occupant through the second method mentioned above.
[0157] The third type is that when the airbag control system 110 further includes a third angle sensor and a second posture sensor, when the controller 112 receives each backrest tilt angle and the posture information of the second occupant, the currently received backrest tilt angle is compared with the previously received backrest tilt angle, and the currently received posture information of the second occupant is compared with the previously received posture information of the second occupant. If the backrest tilt angle and the posture information of the second occupant do not change, it is determined that no posture change event is detected, that is, it is determined not to adjust the deployment angle of the baffle of the airbag assembly 111. If one of the backrest tilt angle and the posture information of the second occupant changes, it is determined that a posture change event is detected, that is, it is determined to adjust the deployment angle of the baffle of the airbag assembly 111, and, according to the corresponding content in the first method or the second method, the third angle is determined, and the baffle of the airbag assembly 111 is controlled to be deployed at the third angle, so that the deployment angle of the airbag assembly 111 is adjusted, thereby further providing effective protection for the second occupant. If the backrest inclination angle and the posture information of the second passenger change, the third angle is determined according to the relevant content in the second method mentioned above, and the baffle of the airbag assembly 111 is controlled to unfold at the third angle, thereby adjusting the unfolding angle of the airbag assembly 111.
[0158] Below, Figure 2 For example, combined with Figure 4 and Figure 5 The airbag module 111 will be described as an example.
[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 a storage structure 11121 and an airbag 11122 as 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, Figure 4 As shown, the airbag 11122 is deployed in front of the occupant. When the airbag 1112 is in the undeployed state, that is, when the airbag assembly 111 is in the undeployed state, as shown in FIG. Figure 2 As shown, the airbag 11122 is stored 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 , the specific manner in which the controller 112 adjusts the position of the airbag assembly 111 may be, for example, that the controller 112 adjusts the position of the airbag 1112 by controlling the first motor 1113 .
[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 An information flow diagram of an airbag control system provided in an embodiment of the present 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 posture sensor.
[0167] The collision sensor is arranged on the vehicle to detect whether the vehicle collides, and, after detecting that the vehicle collides, sends the collision information to the controller. Other sensors have been described above and will not be described again here.
[0168] The control module may include a controller. In addition to realizing the related functions mentioned above, the controller is also used to receive and respond to collision information to ignite the airbag assembly so that the airbag assembly is in a deployed state.
[0169] The execution module may include an airbag assembly, which has been described above and will not be described again here.
[0170] Next, combine Figure 6 An exemplary operation process of installing an airbag control system in a vehicle is described below.
[0171] The first position sensor monitors the position of the movable seat. The monitored position of the movable seat is used as a part of the travel information of the movable seat. And after the movable seat moves under the action of its second motor, the running displacement of the second motor is used as a part of the travel information of the movable seat. In other words, the travel information of the movable seat includes the monitored position of the movable seat and the running displacement of the second motor after the position of the movable seat changes.
[0172] The controller adjusts the position of the airbag assembly according to 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 tilt angle of the backrest of the movable seat to obtain the tilt angle of the backrest of the movable seat. The second posture sensor monitors the posture information of the second occupant on the movable seat to obtain the posture information of the second occupant.
[0174] The controller controls the deployment angle of the baffle of the airbag module according to the tilt angle of the backrest of the movable seat and the posture information of the second occupant.
[0175] The collision sensor detects whether the vehicle collides, and after the vehicle collides, sends the collision information to the controller. The controller receives and responds to the collision information to ignite the airbag assembly to put the airbag assembly in a deployed state.
