In addition, some features, structures, or characteristics in one or more embodiments of the present application can be appropriately combined. It should be noted that the upper, lower, front, rear, inner, and outer in the following description are used to reflect the relative position and/or direction between the various parts of the object, and the direction in which the vehicle normally travels forward is the forward reference.

Referring to FIGS. 1, 2, 3A and 3B, in one embodiment, the airbag module 10 of the vehicle includes an airbag 1 and a gas system 2, and the gas system 2 provides gas for the deployment of the airbag 1. 1, the installation position of the airbag 1 is inside the vehicle's anti-collision beam 20, or it can be suspended below the vehicle's anti-collision beam 20, as shown by the airbag 101 indicated by the dashed line in FIG. 1, or it can be It is installed above the anti-collision beam 20 of the vehicle, at the position shown by the airbag 102 indicated by the dashed line in FIG. 1. As shown in FIG. 2, the fixing method of the airbag 1 can be fixed by a bracket 111. For example, the airbag 1 is installed on the inner side of the anti-collision beam 20 of the vehicle. It can be deployed outside the vehicle by bypassing the anti-collision beam 20. Specifically, it may be as shown in FIG. In order to bypass the anti-collision beam 20, first break down the lower front cover 30 of the vehicle, and then expand it upwards to the front of the front face 40 of the vehicle, but not limited to this, it can also be broken down first. After the square outer cover 30, it expands upward and downward to the front of the vehicle at the same time, including the front of the front face 40 of the vehicle and a part of the area between the front face 40 of the vehicle and the ground, but it does not touch the ground. The structure of the airbag 1 after deployment can be referred to as shown in FIG. 3A and FIG. 3B, where FIG. 3B shows that the airbag 1 of the own vehicle 100 is deployed and contacted with the opponent vehicle 200 when a collision occurs. It can be understood that the outer cover 30 under the front of the vehicle can also be replaced or partially replaced with an air intake grille, which can be adjusted according to actual requirements. As for the guidance of the deployment direction of the airbag 1, refer to the bottom-up deployment guidance structure and guidance method of the knee airbag (KAB) in the prior art, or refer to the passenger airbag ( Passenger Airbag, PAB) The guiding structure and method of simultaneously expanding upward and downward from the middle, will not be repeated here. The beneficial effect of arranging the airbag module 10 is to ensure the strength of the anti-collision cross beam 20 so that it can play a corresponding role in the event of a collision and improve the road compatibility of the vehicle. The principle is that by installing the airbag 1 in at least one of the inside, above, or below the anti-collision beam 20, it is deployed around the anti-collision beam 20, and the anti-collision beam caused by passing the airbag 1 through the anti-collision beam 20 is avoided. Damage to the strength of 20 affects its performance. It can be understood that, in the embodiment shown in FIG. 1, the airbag 1 deployed to the outside of the vehicle is deployed to the front of the vehicle, but it is not limited to this. The airbag can also be installed on the anti-collision beam at the rear of the vehicle to enhance For the protection of the rear of the vehicle, the airbag deployment to the outside of the vehicle at this time can also be the deployment of the airbag to the rear of the vehicle. Preferably, in some embodiments, since the airbag 1 does not need to be deployed through the anti-collision beam 20, an anti-collision foam 60 can be provided on the outer side of the anti-collision beam 20 to further absorb the impact of the collision and improve vehicle compatibility.

Continuing to refer to FIG. 1, in some embodiments, the exterior of the vehicle is the front of the vehicle, and the airbag 101 is located above the anti-collision beam 20. When the airbag 101 is deployed, the airbag 101 is deployed in the direction of breaking through the upper cover 50 of the front of the vehicle. From the front of the vehicle, it can be understood that the outer cover 50 above the front of the vehicle can also be replaced or partially replaced with an air intake grille, which can be adjusted according to actual requirements. After the airbag 101 is deployed to the outside, the airbag 101 is mainly deployed to the front of the front face 40 of the vehicle, and also partially to the front of the hood 70. This arrangement can be applied to vehicles with a lower chassis or a collision event with a higher collision part, thereby improving the road of the vehicle. compatibility. Similarly, the airbag 102 is located under the anti-collision beam 20. When the airbag 102 is deployed, the outer cover 30 under the front of the vehicle is first broken downwards, and then expanded to the front of the front face 40 of the vehicle. The outer cover 50 can also be replaced or partially replaced with an air intake grille, which can be adjusted according to actual requirements. Such a setting can be applied to a vehicle with a higher chassis, or a collision event with a lower collision part, so as to improve the road compatibility of the vehicle. It can be understood that the airbag 1, the airbag 101, and the airbag 102 described above can be installed separately or in combination.

Referring to FIG. 2, in one or more embodiments, the specific structure of the gas system 2 may include a gas generator 21 and an inflatable tube 22. The gas generator 21 is fixed by a bracket 211, and the inflatable tube 22 is fixed by a bracket 221. The gas generator 21 can receive the deployment signal of the airbag 1 and explode, and quickly generates a large amount of gas. The gas is delivered to the airbag through the inflation tube 22. The gas generator 21 is installed at the installation position outside the anti-collision beam 20, and the installation position is at least 200mm. The length of the space is enough. The beneficial effect of this arrangement is that the force exerted by the entire airbag module 10 on the anti-collision beam 20 can be dispersed, and the airbag module 10 can be arranged in other areas in the vehicle to avoid excessively crowded distribution of components in the vicinity of the anti-collision beam 20. It can also prevent the gas generator 21 from being damaged only in a low-speed collision, so that the anti-collision effect of the anti-collision beam 20 and the operation of the gas generator 21 are reliable, and the road compatibility of the vehicle is improved. Preferably, in some embodiments, the installation location may specifically be a headlight bracket (not shown) of the vehicle, which not only ensures a stable installation effect, but also facilitates the arrangement of the inflation tube 22, but the installation location is not limited to this. , It can also be the location in the engine compartment. It can be understood that the specific form of the gas system 2 is not limited to the content introduced in the above embodiment. For example, the gas system 2 can use a high-pressure gas tank to inflate the airbag 1 without the gas generator 21, and for example, the gas system 2 can be unnecessary. The inflation tube 22, that is, the gas generator 21 is integrated into the inside of the airbag 1, so that the inflation tube 22 is omitted.

Continuing to refer to FIG. 1, in some embodiments, the airbag module 10 may further include a waterproof layer 4 that covers the airbag 1 to provide waterproof protection for the airbag. The specific material of the waterproof layer 4 can be plastic, and the gap of the package is also sealed with a waterproof sealant. The inventor found that since the airbag 1 bypasses the anti-collision beam 20 for deployment instead of passing through the anti-collision beam 20, it has a higher probability of wading during operation. Therefore, the airbag 1 needs to be waterproofed to protect it when it needs to be deployed. It can be deployed quickly, avoiding the airbag wading and affecting its deployment speed. Preferably, in some embodiments, a sealing structure, such as a sealing ring, or a sealant, is also provided for the connection part (not shown) of the gas generator 21 for transmitting the unfolding signal to the wire harness to prevent it from wading failure. It can be understood that the transmission of the unfolding signal is not limited to the wired transmission using the wire harness, and can also be transmitted in the manner of wireless communication.

Referring to FIG. 4, in some embodiments, the calculation and analysis of the deployment signal of the airbag module 10 may be performed by the safe state system 3, that is, the airbag module 10 and the safe state system 3 are included in a safety system 1000. The safety status system 3 may include a monitoring system 31 and an integrated safety domain control unit 32. The monitoring system 31 may include a vehicle external information monitoring module 311 and a body attitude monitoring module 312. The vehicle external information monitoring module 311 is used to monitor obstacles around the body and collect Obstacle data around the vehicle body. Obstacles here refer to obstacles in a broad sense, which refer to collision objects on the road that may collide. The body attitude monitoring module 312 is used to monitor body movement and body attitude. The integrated safety domain control unit 32 calculates the collision form between the vehicle and the obstacle based on the data collected by the vehicle external information monitoring module 311 and the body attitude monitoring module 312, including the relative collision speed and the collision overlap rate, according to the relative collision speed and The collision overlap rate judges whether to output the expansion signal to the gas generator 21; wherein the judgment conditions for controlling the output of the expansion signal include whether the collision relative speed is greater than the first speed threshold V1 and whether the collision overlap rate is greater than the first overlap rate threshold X1. Specifically, in a certain collision state, the integrated safety domain control unit 32 calculates that if the relative collision speed is less than the first speed threshold V1, and/or the collision overlap rate is less than the first overlap threshold X1, then it outputs a control signal to keep folded The gas generator 21 to the airbag module 10 keeps the airbag 1 folded. If the relative collision speed is greater than the first speed threshold V1, and the collision overlap rate is greater than the first overlap threshold X1, it can be determined that the airbag 1 can be deployed to improve road compatibility in the collision mode. In this way, the airbag 1 can have a more sufficient deployment time, and can be deployed effectively in a timely manner according to the vehicle's collision form, thereby improving the road compatibility of the vehicle. The principle is that since the airbag 1 needs to bypass the anti-collision beam 20 to deploy, the airbag 1 needs a slightly longer deployment event compared to directly passing through the anti-collision beam 20. By integrating the safety domain unit 32, it will be more quickly and accurately determined in advance whether the airbag 1 needs to be deployed to improve road compatibility. The integrated safety domain unit 32 uses the relative collision speed and the collision overlap rate as judgment conditions to determine whether to output the deployment signal to the inflator 21 to deploy the airbag 1, which is lower than the first speed threshold V1 and/or lower than the first overlap rate threshold X1 That is, the airbag 1 does not need to be deployed, so that the airbag 1 can improve the road compatibility more targeted, and avoid the danger caused by the accidental triggering of the airbag 1. There is also no need to perform the judgment and calculation of whether to deploy the airbag 1 in a mid-to-low-speed collision, which increases the computing speed of the integrated safety domain unit 32 and improves road compatibility.

In some embodiments, the judgment condition for the integrated safety domain control unit 32 to output the deployment signal may also include whether deploying the airbag 1 in a collision mode reduces the damage of the vehicle; if not, the integrated safety domain control unit 32 outputs a retracted signal control The airbag 1 remains folded. Specifically, for example, the location of the collision is not the protected area covered by the airbag 1, and for example, the vehicle external information monitoring module 311 monitors and recognizes that the quality of the obstacle in the collision is much greater than that of the own vehicle, such as a large truck or a bus. Unfolding the airbag 1 can not reduce the injury, and the integrated safety zone control unit 32 controls the airbag 1 to remain folded.

The monitoring system 31 may also include an in-vehicle monitoring module 313, which is used to monitor the mental state of the driver in the vehicle, and collect the mental state data of the driver in the vehicle. The body posture data and the mental state data of the driver in the vehicle calculate the possibility that the driver notices the collision with the obstacle, and calculate the collision form according to the possibility, and determine whether to output a deployment signal. The mental state data of the in-vehicle driver includes one or a combination of the in-vehicle driver's health status data and the in-vehicle driver's facial data. The collection of the above data can be realized by the hardware of the camera and/or the in-vehicle radar. Specifically, the health status data monitored by the camera may include, for example, heartbeat information, and the facial data information may include facial emotional state information (such as excitement, anger), facial fatigue state information (such as blinking frequency, hitting breath), and facial sight information. (For example, the camera tracks the person’s line of sight to determine whether the driver notices the obstacle), facial orientation information (for example, the head turn of the driver and the passenger is analyzed according to the face orientation to determine whether the person is focusing on the front), The in-vehicle radar can perform in-vehicle live body detection and heartbeat detection functions. For example, according to the detection of the driver’s mental state and/or health status, it can correct the calculation of the relative collision speed and/or the collision overlap rate for vehicle collisions, and update whether to output The judgment result of the unfolding signal, for example, the integrated safety domain control unit 32 calculates that the possibility of the driver in the vehicle noticing a collision with an obstacle is low, then the relative speed of the collision in the calculation result of the collision form will increase, and the collision overlap rate will increase . In this way, the deployment signal can be output more timely and accurately to deploy the airbag 1 and improve the road compatibility of the vehicle. It can be seen that with the in-vehicle monitoring module 313, the integrated safety domain control unit 32 can integrate the information of the driver’s mental state, the exterior of the vehicle, and the body posture to calculate the collision shape, so that the calculation result is more accurate and the closest The actual road conditions and the result of own vehicle conditions.

It can be understood that the integrated security domain control unit 32 in the previous embodiment may include one or more hardware processors, such as a system on a chip (SOC), a microcontroller, and a microprocessor (for example, an MCU chip or a 51 single-chip microcomputer). , Reduced instruction set computer (RISC), application specific integrated circuit (ASIC), application specific instruction integrated processor (ASIP), central processing unit (CPU), graphics processing unit (GPU), physical processing unit (PPU), microcontroller Unit, digital signal processor (DSP), field programmable gate array (FPGA), advanced RISC machine (ARM), programmable logic device (PLD), any circuit or processor capable of performing one or more functions, etc. One or more combinations.

Step A. Provide an airbag module 10, which includes an airbag 1, which can be deployed to the outside of the vehicle;

Referring to FIG. 6, in one or more embodiments, in step A, setting the condition for determining the deployment of the airbag 1 includes: Threshold X1, the airbag 1 is deployed. If the relative speed of the vehicle collision is less than the first speed threshold V1 and/or the collision overlap rate of the vehicle is less than the first overlap rate threshold X1, the airbag 1 remains folded. Preferably, continuing to refer to FIG. 6, in some embodiments, the judgment condition may further include, if deploying the airbag 1 can reduce the injury value of the vehicle, deploy the airbag 1, and if the injury value cannot be reduced, keep the airbag 1 folded.
