In addition, the character "/" herein generally indicates that the former and latter associated objects are in an "or" relationship.
Fig. 1 is a schematic structural diagram of a side impact protection system according to an embodiment of the present application. The side impact protection system shown in fig. 1 includes: a controller 100, a side impact acceleration sensor 200, a seat pressure sensor 300, and an airbag module 400. Wherein the side impact acceleration sensor 200, the seat pressure sensor 300, and the airbag module 400 are connected to the controller 100. The side impact acceleration sensor 200 is used to collect the side impact acceleration of the vehicle during side impact. The seat pressure sensor 300 is configured to acquire a current seat pressure value of the vehicle seat, and specifically, the seat pressure sensor 300 may acquire the seat pressure value of the vehicle seat in real time or periodically and send the seat pressure value to the controller 100 for use. The vehicle seats include, but are not limited to, a main seat, a passenger seat, a left rear seat, a right rear seat, and the like.
Optionally, the side impact protection system 1 may further include a head position sensor 500, and the head position sensor 500 is also connected to the controller 100. The present application is not limited to the specific number and the installation position of the controller 100, the side impact acceleration sensor 200, the seat pressure sensor 300, the airbag module 400, and the head position sensor 500. Specific examples thereof include:
the controller 100 is provided at the bottom of the vehicle seat, and the airbag module 400 is provided at the inner side of the upper back portion or at the inner side of both sides of the headrest of the vehicle seat. The head position sensor 500 is disposed inside a position in the vehicle seat that is highly aligned with the head of the user. The head position sensor 500 is used to detect a head position of a user on the vehicle seat, specifically, for example, to detect whether the head position of the user is located at a preset head center position (also referred to as a seat center position) in the vehicle seat. In practical applications, the head position sensor 500 may be replaced by a camera, a pressure sensor, or other sensors capable of detecting the head position of the user, and the present application is not limited thereto.
When the head position sensor 500 detects that the head position of the user is not located at the seat center position, a prompt message may be issued to the user through the controller 100 to prompt the occupant to sit centrally. When the head of the user is in the middle position of the seat, the controller 100 controls the airbag module 400 to extend out, so that the problems that the head of the user is not in the middle position and cannot be well protected, the head and the cervical vertebra of the user are damaged and the like are solved. In contrast, in the event of a side impact, when the head position sensor 500 is in the seat center position, the controller 100 may control the airbag module 400 accordingly, for example, control the protruding angle of the airbag module 400. The control embodiment of the airbag module will be described in detail below in the present application, and will not be described here.
The airbag module 400 can be installed according to actual requirements, for example, please refer to fig. 2, which is a schematic structural diagram of another side impact protection system provided in the embodiment of the present application. The airbag module 400 may specifically include, but is not limited to, the main-driver left airbag module 401, the main-driver right airbag module 402, the copilot left airbag module 403, the copilot right airbag module 404, the left rear left airbag module 405, the left rear right airbag module 406, the right rear left airbag module 407, and the right rear left airbag module 408 shown in fig. 2. The airbag module 400 may be installed according to the number of seats and the position of the seat of the vehicle, and the airbag module 400 may be installed inside the upper portion of the backrest of the vehicle seat or inside both sides of the headrest. The seat pressure sensor 300 may be disposed under the vehicle seat, which is determined according to the number of the vehicle seats, for example, 4 seat pressure sensors are illustrated in the figure, which are a seat pressure sensor 301, a seat pressure sensor 302, a seat pressure sensor 303, and a seat pressure sensor 304.
For example, please refer to fig. 3 and fig. 4 together, which are schematic views of two possible side impact protection scenarios provided by the embodiment of the present application. Therein, fig. 3 shows in particular a side view of the side impact protection, as a drawing showing a left airbag module on a vehicle seat. Fig. 4 specifically shows a front view of side impact protection, such as illustrating a left airbag module 401 and a right airbag module 402 on a vehicle seat, and an extended/blown airbag of the left and right airbag modules.
Based on the above embodiments, please refer to fig. 5, which is a schematic flow chart of a side impact protection method according to an embodiment of the present application. The method shown in fig. 5 is applied to the side impact protection system shown in fig. 1-4, and particularly to the controller 100 of the side impact protection system, and comprises the following implementation steps:
s501, when the vehicle is subjected to side impact, acquiring the side impact acceleration of the vehicle and the seat pressure value of a target seat.
When a side impact occurs to a vehicle, the side impact acceleration of the vehicle is collected through the side impact acceleration sensor 200, and the seat pressure value (also called as the pressure value of a seat pressure signal) of a target seat (any vehicle seat in the vehicle) is collected through the seat pressure sensor 300.
And S502, judging whether the side impact acceleration and the seat pressure value meet preset air bag control conditions.
The airbag control conditions described herein are system-customized conditions for controlling the airbag module 400 in the vehicle, such as, but not limited to, conditions such as side impact acceleration greater than or equal to a predetermined acceleration, seat pressure greater than or equal to a predetermined pressure, and the like. The preset acceleration and the preset pressure value are both set by a system user, and can be set according to the actual requirement of the system, for example, the preset acceleration ay0 can be any value from 10 to 30.
In one embodiment, the present application can determine whether the side impact acceleration is greater than or equal to a predetermined acceleration and determine whether the seat pressure value is greater than or equal to a predetermined pressure value. The side impact acceleration and the seat pressure value are judged according to the sequence, the application is not limited, for example, whether the side impact acceleration is larger than or equal to the preset acceleration or not can be judged firstly, and whether the seat pressure value is larger than or equal to the preset pressure value or not can be judged firstly. When the side impact acceleration is judged to be greater than or equal to the preset acceleration and the seat pressure value is judged to be greater than or equal to the preset pressure value, the method can continue to execute the step S503; conversely, the airbag module 400 may not be controlled, i.e., the airbag module 400 is not activated.
And S503, controlling an airbag module arranged on the target seat to realize side collision protection of the vehicle.
Specifically, the present application may acquire a user's head position on the vehicle seat through the head position sensor 500 and determine a position angle deviation from the user's head position, the position angle deviation being an angle deviation between the user's head position and a seat center position. Finally, the present application may control the airbag module 400 disposed on the vehicle seat according to the angular position deviation, and the specific implementation of the control is not limited, and specifically, for example, the present application may control the airbag module 400 on the vehicle seat according to a section range in which the angular position deviation is located.
In one embodiment, when the section range in which the positional angle deviation is located is a first section range, the present application may control the airbag module 400 (specifically, the airbag accommodated in the airbag module 400) provided in the vehicle seat to protrude at a preset first angle. When the range in which the position angle deviation is located is the second range, the airbag module 400 provided in the vehicle seat may be controlled to extend out at a preset second angle. When the range in which the position angle deviation is located is a third range, the airbag module 400 provided in the vehicle seat may be controlled to extend out at a preset third angle. When the lower limit value of the first interval range, the lower limit value of the second interval range and the lower limit value of the third interval range are sequentially reduced, the preset first angle, the preset second angle and the preset third angle are sequentially reduced. The first interval range, the second interval range, the third interval range, the preset first angle, the preset second angle and the preset third angle are all set by system customization, for example, set according to actual needs of a system, and the application is not limited. And the range intervals included in the first interval range, the second interval range and the third interval range are not overlapped with each other.
For example, the present application may control the airbag module as set forth in table 1 below.
TABLE 1
Figure BDA0003609819260000091
Figure BDA0003609819260000101
In table 1 above, ay represents the side impact acceleration of the vehicle, and ay0 represents the preset acceleration.
With the above-described embodiments of the present application, when a side collision of a vehicle is considered, the vehicle swings back and forth repeatedly and greatly under impact force and inertia, and may damage the cervical vertebrae and the head. Compared with the prior art, the safety protection device has the advantages that the head can be effectively protected, and the safety performance during side collision can be further improved. The side collision protection device (system) can move along with the position of the seat, is not influenced by the position of the seat, and can meet different requirements of human body sitting postures; the stretching angle of the air bag can be adjusted according to different human bodies, so that the human body can meet the requirements of human bodies with different heights; after the air bag module is used during the side collision of the vehicle, a new air bag module can be placed into the air bag module box, so that the seat can be recycled, and the use cost is reduced.
It can be seen that by implementing the embodiment of the application, when a vehicle is in side impact, the application acquires the side impact acceleration of the vehicle and the seat pressure value of a target seat; judging whether the side impact acceleration and the seat pressure value meet preset air bag control conditions or not; and if so, controlling an airbag module arranged on the target seat to realize side collision protection of the vehicle.
