[0029] Reference below Figure 1-Figure 3 A control system 100 for an airbag according to an embodiment of the present invention is described.

[0030] Reference Figure 1 , Figure 2 and Figure 3 According to the airbag control system 100 of the embodiment of the utility model, it includes: a collision sensor 1, an intermediate controller 2 and an airbag controller 3. Among them, the collision sensor 1 is used to detect the collision information of the vehicle body, the intermediate controller 2 is connected to at least one collision sensor 1, the intermediate controller 2 is at least used to receive and transmit the collision information sent by the collision sensor 1, and the airbag controller 3 is at least connected to the intermediate controller 2, and the airbag controller 3 is at least used to receive and process the collision information sent by the intermediate controller 2 to control whether the airbag is deployed.

[0031] In an actual application scenario of the airbag control system 100 of an embodiment of the utility model, the collision sensor 1 detects the collision information of the vehicle 200 in real time. At least one collision sensor 1 can send the collision information to the intermediate controller 2, and then the intermediate controller 2 transmits the collision information from the collision sensor 1 to the airbag controller 3. After receiving the collision information from the intermediate controller 2, the airbag controller 3 analyzes and judges the data to control whether the airbag is opened. When the airbag controller 3 detects abnormal collision information, it sends an ignition command to the airbag trigger 4 to ignite the airbag.

[0032] It should be noted that the intermediate controller 2 is a controller other than the airbag controller 3 on the vehicle 200, which may be a domain controller, an engine controller, a transmission controller, an air conditioning controller, etc., which is used to control various devices in the vehicle 200. These controllers are distributed in different positions of the vehicle body, and the vehicle 200 communicates with most of the controllers to achieve intelligent control. In order to reduce the use of the wiring harness 5, the embodiment of the utility model uses some controllers on the vehicle 200 as the intermediate controller 2 to transfer the collision information of the collision sensor 1.

[0033] According to the airbag control system of the embodiment of the utility model, at least one collision sensor 1 can be connected to the adjacent intermediate controller 2 through the wiring harness 5, and then the collision information is sent to the airbag controller 3 through the intermediate controller 2, which effectively reduces the use of the wiring harness 5 and reduces the cost.

[0034] In some embodiments, the airbag controller 3 is wirelessly connected to the intermediate controller 2 .

[0035] In the embodiment of the utility model, the airbag controller 3 and the intermediate controller 2 do not need to be connected through the wiring harness 5, which reduces the cost of the vehicle 200, and there is no need to set a corresponding wiring path on the body, which simplifies the body structure and further reduces the cost of the vehicle 200.

[0036] In some further embodiments, the airbag controller 3 and the intermediate controller 2 are connected via a controller area network CAN (Controller Area Network).

[0037] CAN is used for communication between various components in the vehicle 200, thereby replacing the connection harness 5, effectively reducing the cost of the vehicle 200, and the data communication of CAN has outstanding reliability, real-time and flexibility.

[0038] In the embodiment of the utility model, the airbag controller 3 is connected to the intermediate controller 2 via a controller area network CAN, thereby ensuring the reliability of information transmission between the airbag controller 3 and the intermediate controller 2.

[0039] In the embodiment of the utility model, after receiving the collision information sent by the collision sensor 1, the intermediate controller 2 converts the collision information sent by the collision sensor 1 and finally sends it to the airbag controller 3 in the form of a CAN message.

[0040] In other embodiments, the intermediate controller 2 may also analyze and process the collision information to improve the safety of vehicle use.

[0041] In some specific embodiments, the intermediate controller 2 is connected to the unlocking structure of the vehicle door to control whether the vehicle door is unlocked. When the intermediate controller 2 detects abnormal collision information, the intermediate controller 2 controls the vehicle door to unlock, making it convenient for people inside or outside the vehicle to open the door, thereby improving the safety of the use of the vehicle 200.

[0042] In some embodiments, a plurality of collision sensors 1 are provided, and the plurality of collision sensors 1 are suitable for being distributed at different positions of the vehicle body for detecting collision information at different positions of the vehicle body, some of the plurality of collision sensors 1 are connected to the intermediate controller 2, and the remaining collision sensors 1 are connected to the airbag controller 3.

[0043] In an embodiment of the utility model, when the airbag control system is working, some collision sensors 1 send collision information to the airbag controller 3 through the intermediate controller 2, and the remaining collision sensors 1 directly send collision information to the airbag controller 3. After the airbag controller 3 processes the collision information from the intermediate controller 2 and the collision sensor 1, it controls whether the airbag is opened by controlling the airbag trigger 4.

[0044] In the above technical solution, part of the collision sensors 1 are connected to the intermediate controller 2 via the wiring harness 5 , which reduces the use of the wiring harness 5 of the part of the collision sensors 1 and reduces the cost.

[0045] In some specific embodiments, at least one of the multiple collision sensors 1 that is closer to the intermediate controller 2 is connected to the intermediate controller 2 via a wiring harness 5 , and the collision sensor 1 that is closer to the airbag controller 3 is connected to the airbag controller 3 via a wiring harness 5 .

[0046] That is to say, a part of the collision sensor 1 is closer to the intermediate controller 2 than the airbag controller 3, so this part of the collision sensor 1 is connected to the intermediate controller 2 through the wiring harness 5; another part of the collision sensor 1 is closer to the airbag controller 3 than the intermediate controller 2, so this part of the collision sensor 1 is connected to the airbag controller 3 through the wiring harness 5.

[0047] In the above technical solution, each collision sensor 1 is connected to a nearby controller via a wiring harness 5, which ensures that the airbag control system 100 can work normally while effectively reducing the use of the wiring harness 5 and reducing the cost.

[0048] Reference Figure 1 , Figure 2 and Figure 3 In other embodiments, a plurality of collision sensors 1 are provided, and the plurality of collision sensors 1 are suitable for being distributed at different positions of the vehicle body. A plurality of intermediate controllers 2 are provided, and the plurality of intermediate controllers 2 are distributed at different positions of the vehicle body, and each intermediate controller 2 is connected to a collision sensor 1 that is close thereto through a wiring harness 5.

[0049] In the above technical solution, multiple intermediate controllers 2 are provided, so that each collision sensor 1 can be connected to the adjacent intermediate controller 2 through the wiring harness 5, which effectively reduces the use of the wiring harness 5, reduces the cost, and optimizes the arrangement of the wiring harness 5.

[0050] In some specific embodiments, the intermediate controller 2 is a domain controller.

[0051] The domain controller of the vehicle 200 is suitable for connecting and controlling at least one device on the vehicle 200, such as a window lift, a door lock, a double flash light, a brake light, an interior light, and the like. The domain controller has a high degree of integration, and is provided with a large number of connection parts for connecting devices. In the embodiment of the utility model, the domain controller is used as the intermediate controller 2, and the wiring harness 5 connected to the collision sensor 1 can be directly connected to the connection part on the domain controller, without changing the structure of the domain controller, thereby reducing the cost of the vehicle 200.

[0052] In some specific embodiments, the intermediate controller 2 is provided with a first plug interface, the collision sensor 1 is provided with a second plug interface, and the two ends of the wiring harness 5 are respectively plugged and matched with the corresponding first plug interface and second plug interface.

[0053] Through the above technical solution, the connection difficulty between the wiring harness 5 and the intermediate controller 2 and the collision sensor 1 is effectively reduced, and the assembly efficiency of the control system is improved. In addition, it is also conducive to the disassembly of the wiring harness 5 and facilitates the maintenance of the vehicle 200.

[0054] It should be understood that the wiring harness 5 and the intermediate controller 2 and the collision sensor 1 may also be connected in other ways, such as welding, fixing with fasteners, etc., as long as the wiring harness 5 is electrically connected to the intermediate controller 2 and the collision sensor 1 respectively, the utility model is not limited to this.

[0056] The left domain controller 21 , the right domain controller 22 and the rear domain controller 23 are respectively connected to at least one collision sensor 1 via a wiring harness 5 .

[0057] In the above technical solution, the left domain controller 21, the right domain controller 22 and the rear domain controller 23 are arranged around the airbag controller 3, and the multiple collision sensors 1 are usually arranged at a position close to the outer surface of the vehicle body, that is, the multiple collision sensors 1 are arranged around the left domain controller 21, the right domain controller 22 and the rear domain controller 23. Compared with the airbag controller 3, each collision sensor 1 is closer to the adjacent domain controller, that is, each collision sensor 1 is connected to the adjacent domain controller through the wiring harness 5, which effectively reduces the use of the wiring harness 5 and reduces the cost.

[0058] In some further embodiments, the plurality of collision sensors 1 include: a left front collision sensor 11, a right front collision sensor 12, a left side collision sensor 13, a right side collision sensor 14, a left rear collision sensor 15 and a right rear collision sensor 16, the left side collision sensor 13 being located between the left front collision sensor 11 and the left rear collision sensor 15, and the right side collision sensor 14 being located between the right front collision sensor 12 and the right rear collision sensor 16.

[0060] In the above technical solution, the airbag control system can monitor the collision information of various positions of the vehicle body in real time through the left front collision sensor 11, the right front collision sensor 12, the left collision sensor 13, the right collision sensor 14, the left rear collision sensor 15 and the right rear collision sensor 16, thereby ensuring the reliability of the airbag control system 100 and improving the safety of the vehicle 200. The above-mentioned multiple collision sensors 1 are respectively connected to the adjacent domain controllers through the wiring harness 5, which greatly reduces the use of the wiring harness 5 and reduces the cost.

[0061] In some specific embodiments, the left front collision sensor 11 and the left side collision sensor 13 are connected to the left domain controller 21 in parallel, the right front collision sensor 12 and the right side collision sensor 14 are connected to the right domain controller 22 in parallel, and the left rear collision sensor 15 and the right rear collision sensor 16 are connected to the rear domain controller 23 in parallel.
