Since the floor of electric vehicles contains battery packs, the waveform strength of side collisions is doubled compared to traditional fuel vehicles, and the degree of injury to far-end occupants in side collisions is also more serious. Far-end occupant protection in car side collisions is receiving more and more attention. Both CNCAP and ENCAP regulations have added side collision conditions to evaluate far-end occupant protection, and far-end occupant protection has become a necessary prerequisite for a vehicle's five-star safety rating.

[0003] Existing distal airbags are usually installed on the inner side of the seat back where the occupants sit. When impacted, the distal airbags are prone to significant displacement due to the impact of the occupants, resulting in a poorer protective effect. Moreover, because the airbags are installed on the seat on the same side as the occupants, they are too close to the protected person, which can easily cause the occupants to be invaded by the outside of the vehicle and squeezed by the distal airbags at the same time, increasing the damage to the occupants in a side collision.

[0046] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0047] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0048] The main solution of the embodiment of the present application is: obtaining the real-time acquisition signal of the seat pressure sensor and the occupant image information acquired by the vehicle camera, and determining the occupant type according to the real-time acquisition signal and the occupant image information; when the occupant type is a large occupant, obtaining real-time driving data, and when it is determined that there is a risk of side collision according to the real-time driving data, obtaining the riding status of the person at the far end point; when there is an occupant at the far end point, determining the collision parameter according to the real-time driving data, and obtaining an ignition signal when the collision parameter is greater than the ignition threshold; and triggering the far airbag generator of the far side seat to explode according to the ignition signal.

[0049] In this embodiment, for the convenience of description, the following description is made by taking the identification of the remote airbag ignition control device as the execution subject.

[0050] Since in the prior art the distal airbag is usually arranged on the inner side of the seat back where the occupant sits, when impacted, the distal airbag is prone to a significant displacement due to the impact of the occupant, resulting in a poorer protective effect; and because the airbag is installed on the seat on the same side as the occupant, it is too close to the protected person, which can easily cause the occupant to be invaded by the outside of the vehicle and squeezed by the distal airbag at the same time, increasing the damage to the occupant in a side collision.

[0051] The present application provides a solution, using the side of the far side seat as an effective support structure to improve the bending resistance of the far side airbag when it is hit by a side impact, and provide stable support for the occupants. At the same time, using the ignition strategy control, according to different working conditions and occupant conditions, the corresponding far side airbag is adaptively selected to ignite, ensuring that the occupants have enough space to move into the car during a side impact, avoiding the occupants from being invaded by the outside of the car and squeezed by the far side airbag at the same time, and reducing the damage to the occupants during a side impact.

[0052] It can be seen from the above embodiments that the present application obtains the real-time acquisition signal of the seat pressure sensor and the occupant image information acquired by the vehicle camera, and determines the occupant type according to the real-time acquisition signal and the occupant image information; when the occupant type is a large occupant, obtains real-time driving data, and when it is determined that there is a risk of side collision according to the real-time driving data, obtains the seating status of the person at the far end point; when there is an occupant at the far end point, determines the collision parameter according to the real-time driving data, and obtains an ignition signal when the collision parameter is greater than the ignition threshold; triggers the remote airbag generator of the remote side seat to explode according to the ignition signal, and adaptively selects the corresponding remote airbag to ignite according to different working conditions and occupant conditions, so as to reduce the damage to the occupant during side collision.

[0053] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a remote airbag ignition control device, etc. The remote airbag ignition control device is taken as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the present application embodiment provides a remote airbag ignition control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the remote airbag ignition control method of the present application.

[0055] In this embodiment, the remote airbag ignition control method includes steps S10 to S30:

[0056] Step S10, obtaining vehicle sensor information, and determining the occupant type and the riding status of the person at the remote point according to the vehicle sensor information.

[0057] It should be noted that the real-time collected signals of the seat pressure sensor include the occupant's weight information and the occupant's weight distribution. The weight information and weight distribution can be used as one of the indicators to measure the occupant type. The occupant image information refers to the image information collected by the panoramic camera located on the roof of the vehicle. The occupant type can be distinguished according to body shape. The occupants can be divided into large occupants and small occupants. Large occupants are occupants who occupy 50% or more of the seat, and small occupants are occupants who occupy less than 50% of the seat. The seating status of the occupants at the far end point is the result of the camera on the top of the vehicle detecting the status of the occupants on the far end seat. The seating status of the occupants at the far end point can include an occupied state and an unoccupied state.

[0058] In a specific implementation, the real-time acquisition signal of the seat pressure sensor can be obtained, and the occupant weight and weight distribution of the occupant can be determined according to the real-time acquisition signal; the occupant image information collected by the vehicle camera can be obtained, and the coverage ratio of the occupant relative to the seat can be determined according to the occupant image information; the occupant type can be determined according to the occupant weight, the weight distribution and the coverage ratio, referring to Figure 2 , Figure 2 The flowchart of the scheme is shown in FIG. 1 . During the driving process of the car, the weight and weight distribution data of the occupants are collected in real time through the seating pressure sensor installed in the seat cushion. Combined with the 360° panoramic camera installed in the middle of the vehicle roof, the panoramic camera can scan the interior of the car (including the main and co-pilot seats and the back row) to determine the body characteristics of the occupants and distinguish them into large occupants (50 percentile and above) and small occupants (below 50 percentile). The camera on the top of the vehicle can detect the status of the occupants in the main and co-pilot seats to detect whether there is anyone sitting in the main or co-pilot seats. When judging the sitting status of the occupants at the far end point, the main and co-pilot seats can be assumed as collision points respectively, that is, when determining the sitting status of the occupants at the far end point of the main driver's seat, the sitting status of the occupants in the co-pilot seat is detected to determine the sitting status of the occupants in the co-pilot seat. The sitting status detection of the occupants at the far end point of the co-pilot seat is also based on the same method.

[0059] Step S20, acquiring real-time driving data, and when it is determined that there is a risk of side collision based on the real-time driving data, determining the collision point, and determining the airbag ignition strategy based on the collision point, the occupant type and the riding status of the occupant at the far end point.

[0060] It should be noted that the airbag ignition strategy is determined by the collision point, occupant type and the riding status of the occupants at the remote point, wherein the airbag ignition strategy includes a large airbag ignition strategy and a small airbag ignition strategy, and the ignition signals corresponding to the large airbag ignition strategy and the small airbag ignition strategy have different target airbags.

[0061] In a specific implementation, the specific implementation process can be described as obtaining real-time driving data, determining the driving speed, acceleration information and radar information based on the real-time driving data; performing collision prediction based on the driving speed, the acceleration information and the radar information to obtain a collision prediction result; when the collision prediction result is a side collision, determining that there is a risk of side collision and determining the collision point; determining the far end point corresponding to the collision point based on the collision point; determining the visual angle of the current vehicle camera, adjusting the vehicle camera based on the visual angle and the far end point, and obtaining image data of the far end point; identifying the image data to obtain the occupant status of the far end point, and determining whether the executed airbag ignition strategy is a large airbag ignition strategy or a small airbag ignition strategy based on the real-time driving data, the occupant type and the occupant status of the far end point. When there is a person sitting at the far end point, when the occupant type at the collision point is detected to be a large occupant, the airbag ignition strategy is determined to be a large airbag ignition strategy; when there is a person sitting at the far end point, when the occupant type at the collision point is detected to be a small occupant, the airbag ignition strategy is determined to be a small airbag ignition strategy. If there is no occupant at the far end point, the far end airbag ignition strategy is not executed.

[0062] Step S30, generating a corresponding ignition signal based on the airbag ignition strategy, and triggering the corresponding target airbag initiator to ignite according to the ignition signal.

[0063] In a specific implementation, when there is an occupant at the far end, the side collision mechanism of the vehicle is in a waiting state. At this time, the collision parameters can be determined according to the real-time driving data, the collision intensity can be determined according to the collision parameters, and the collision intensity is compared with the ignition threshold. When the collision intensity is greater than the ignition threshold, an ignition signal is obtained. When a large occupant experiences a side collision, if the far-end airbag in the seat on the same side is detonated, since the far-end airbag is on the seat on the same side as the occupant, it is too close to the protected person, and the occupant has insufficient space to move, which can easily cause the occupant to be simultaneously intruded by the outside of the vehicle and squeezed by the far-end airbag, increasing the damage to the occupant during a side collision. Therefore, different ignition strategies are adopted for occupants of different sizes facing side collisions. When a high-level auxiliary driving system or laser radar, camera and sensor collect driving environment and vehicle information in real time and analyze it in combination with navigation data, and judge that the vehicle is about to have a side collision and it is inevitable, the seat occupancy monitoring sensor is used to judge whether there is someone sitting on the seat far away from the collision side. At this time, in order to prevent collision injuries between two passengers, the collision sensor will determine whether to ignite the remote airbag according to whether the collision intensity reaches the ignition threshold of the airbag. When judging to ignite the remote airbag, the corresponding target airbag generator is triggered to ignite according to the ignition signal.

[0064] In a feasible implementation manner, the step of generating a corresponding ignition signal based on the airbag ignition strategy and triggering the corresponding target airbag initiator to ignite according to the ignition signal includes:

[0065] When the airbag ignition strategy is a large-size airbag ignition strategy, generating a remote ignition signal;

[0066] The remote ignition signal is transmitted to the remote airbag generator to trigger the remote airbag generator to explode.

[0067] In a specific implementation, when the airbag ignition strategy is a large-size airbag ignition strategy, a remote ignition signal is generated, and when the remote airbag generator of the remote seat is triggered to ignite according to the remote ignition signal, the ignition signal is specifically transmitted to an electronic control unit, so that the electronic control unit transmits the ignition signal to the airbag generator of the remote airbag, so that the remote airbag generator of the remote seat is ignited. If it is determined that the occupant on the near-collision side is a large-size occupant (50 percentile and above), the remote airbag on the remote seat is controlled to ignite, such as Figure 3 As shown, this ensures that the occupants have enough space to move into the car when they are hit from outside, and will not be overly squeezed by the distal airbag, increasing the damage to the occupants in a side collision.

[0068] In a feasible implementation manner, the step of determining target airbag inflator information based on the airbag ignition strategy, generating a corresponding ignition signal based on the target airbag inflator, and triggering the airbag inflator to ignite according to the ignition signal further includes:

[0069] When the airbag ignition strategy is a small-sized airbag ignition strategy, generating a proximal point ignition signal;

[0070] The proximal ignition signal is transmitted to the proximal airbag generator to trigger the proximal airbag generator to explode.

[0071] In a specific implementation, when the airbag ignition strategy is a small-body airbag ignition strategy, a proximal ignition signal is generated, and when the distal airbag generator of the proximal seat is triggered to explode according to the ignition signal, the ignition signal is specifically transmitted to an electronic control unit, so that the electronic control unit transmits the ignition signal to the proximal airbag generator, so that the distal airbag generator of the proximal seat is exploded. Figure 4 , Figure 5 As shown, small-sized people are farther away from the distal airbag due to their small body size and have enough space to move into the vehicle when they are hit by a collision from outside the vehicle. At this time, detonating the distal airbag on the proximal seat can protect the occupants in time and prevent them from being injured by a collision with the occupants on the distal side.

[0072] The present embodiment provides a remote airbag ignition control method, which obtains vehicle sensor information, determines the occupant type and the seating status of the occupant at the remote point according to the vehicle sensor information; obtains real-time driving data, and when it is determined that there is a risk of side collision according to the real-time driving data, determines the collision point, and determines the airbag ignition strategy based on the collision point, the occupant type and the seating status of the occupant at the remote point; generates a corresponding ignition signal based on the airbag ignition strategy, triggers the corresponding target airbag generator to explode according to the ignition signal, and adaptively selects the corresponding remote airbag ignition according to different working conditions and occupant conditions to reduce damage to the occupant during a side collision.

[0073] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the remote airbag ignition control method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.

[0074] The present application also provides an airbag, which is installed on the inner side of the main driver's seat and the co-driver's seat respectively, wherein the airbag close to the collision point is a proximal airbag, which includes a proximal airbag generator, and the airbag far from the collision point is a distal airbag, which includes a distal airbag generator, and the proximal airbag and the distal airbag are respectively installed on the corresponding seat sides, and the seat sides provide support for the proximal airbag and the distal airbag, and implement the distal airbag ignition control method as described in the above embodiment. Figure 6 As shown, since the detonated distal airbag is installed on the distal side seat, after the airbag is deployed, the side of the seat is used as support, the support area is large and the structure is stable, which improves the bending resistance of the airbag when it is hit from the side, and provides stable support for the occupants after the airbag is deployed.

[0075] This application also provides a remote airbag ignition control device, please refer to Figure 7 , the remote airbag ignition control device comprises:

[0076] The occupant detection module 10 is used to obtain vehicle sensor information and determine the occupant type and the riding status of the person at the remote point according to the vehicle sensor information;
