[0046] It should be understood that the specific embodiments described herein are merely intended 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 solutions of the present application, the specific embodiments will be described in detail below in conjunction with the drawings and the specific embodiments.

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

[0049] In the present embodiment, for the convenience of description, the following describes the identification of the far-end airbag ignition control device as the execution subject.

[0050] Since the far-end airbag in the prior art is usually arranged inside the seat backrest of the seat where the occupant sits, when impacted, the far-end airbag is easy to be greatly deviated under the impact of the occupant, resulting in poor protection effect; and because the airbag is installed on the same side seat as the occupant, it is too close to the protected person, which is easy to cause the occupant to be simultaneously invaded from outside the vehicle and squeezed by the far-end airbag, increasing the injury to the occupant in side collision.

[0051] The application provides a solution which uses the side of the remote seat as an effective support structure to improve the bending resistance of the remote airbag when subjected to lateral impact and to provide stable support for the occupant. Meanwhile, by using ignition strategy control, the corresponding remote airbag ignition is adaptively selected according to different working conditions and occupant conditions, so that the occupant has sufficient moving space into the vehicle during side impact, the occupant is prevented from being subjected to intrusion from outside the vehicle and extrusion from the remote airbag at the same time, and the injury to the occupant during side impact is reduced.

[0052] From the above embodiment, it can be known that the application acquires real-time acquisition signals of a seat pressure sensor and occupant image information collected by a vehicle camera, determines an occupant type according to the real-time acquisition signals and the occupant image information, acquires real-time driving data when the occupant type is a large-size occupant, acquires a remote point occupant state when it is determined that there is a side collision risk according to the real-time driving data, determines a collision parameter according to the real-time driving data when the remote point has an occupant, obtains an ignition signal when the collision parameter is greater than an ignition threshold, triggers a remote airbag inflator of a remote side seat to burst according to the ignition signal, adaptively selects corresponding remote airbag ignition according to different working conditions and occupant conditions, and reduces the injury to the occupant during side impact.

[0053] It should be noted that the execution subject of the embodiment can 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 and the like, or an electronic device, a remote airbag ignition control device and the like capable of realizing the above functions. The embodiment and the following embodiments are described below by taking the remote airbag ignition control device as an example.

[0054] Based on this, the application embodiment provides a remote airbag ignition control method, which is described below with reference to Figure 1 , Figure 1 The figure is a flowchart of the first embodiment of the remote airbag ignition control method of the application.

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

[0056] Step S10, acquiring vehicle sensor information, determining an occupant type and a remote point occupant state according to the vehicle sensor information.

[0057] It should be noted that the real-time acquisition signal of the seat pressure sensor includes the weight information of the occupant and the weight distribution of the occupant, and the weight information and the weight distribution can be used as one of the indicators for measuring 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 the body size, and the occupant can be divided into a large body type occupant and a small body type occupant, wherein the large body type occupant is an occupant occupying more than 50% of the seat, and the small body type occupant is an occupant occupying less than 50% of the seat. The remote point personnel riding state is the result of detecting the riding state of the personnel on the remote seat by the camera on the roof of the vehicle. The remote point personnel riding state can include a person riding state and a no one riding state.

[0058] In a specific implementation, the occupant weight and the weight distribution of the occupant can be determined by acquiring the real-time acquisition signal of the seat pressure sensor according to the real-time acquisition signal. The occupant image information collected by the vehicle camera is acquired, and the coverage ratio of the occupant relative to the seat is determined according to the occupant image information. The occupant type is determined according to the occupant weight, the weight distribution and the coverage ratio. Referring to Figure 2 , Figure 2 The scheme flowchart is shown in the figure. During the driving of the vehicle, the weight and weight distribution data of the occupant are collected in real time by the riding pressure sensor installed in the seat cushion, and the 360° panoramic camera installed in the middle of the roof of the vehicle is combined. The panoramic camera can scan around the vehicle (including the main driver and the rear seat) to determine the body size characteristics of the occupant and distinguish between a large body type occupant (more than 50%) and a small body type occupant (less than 50%). The camera on the roof of the vehicle can detect the riding state of the personnel on the main driver seat and the co-driver seat, and can be used to detect whether there is a person riding on the main driver seat or the co-driver seat. When determining the remote point personnel riding state, the main driver seat and the co-driver seat are assumed to be the collision points, respectively. That is, when determining the remote point personnel riding state of the main driver seat, the personnel riding state of the co-driver seat is detected, and the personnel riding state of the co-driver seat is determined based on the same method.

[0059] In step S20, real-time driving data is acquired, and when it is determined that there is a side collision risk according to the real-time driving data, a collision point is determined, and an airbag firing strategy is determined based on the collision point, the occupant type and the remote point personnel riding state.

[0060] It should be noted that the airbag firing strategy is determined based on the collision point, the occupant type and the remote point personnel riding state. The airbag firing strategy includes a large body type airbag firing strategy and a small body type airbag firing strategy, and the target point of the firing signal corresponding to the large body type airbag firing strategy and the small body type airbag firing strategy is different.

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

[0062] In step S30, a corresponding ignition signal is generated based on the airbag ignition strategy, and a corresponding target airbag generator is triggered to burst according to the ignition signal.

[0063] In a specific implementation, when there is a passenger at the far end point, the side collision mechanism of the vehicle is in an activated state, at this time, collision parameters can be determined according to real-time driving data according to the real-time driving data, the collision strength is determined according to the collision parameters, the collision strength is compared with the ignition threshold, and the ignition signal is obtained when the collision strength is greater than the ignition threshold. When a large body passenger experiences a side collision, if the far end airbag in the same side seat is burst, because the far end airbag is on the same side seat of the passenger, the distance to the protected personnel is too close, and the passenger has insufficient moving space, the passenger is easily subjected to extrusion of the far end airbag and the outside intrusion at the same time, increasing the injury to the passenger in the side collision. Therefore, different ignition strategies are adopted for different body types of passengers when facing a side collision. When a high-level auxiliary driving system or a laser radar, a camera and a sensor collect real-time driving environment and vehicle information and analyze the data combined with navigation data to determine that the vehicle is about to experience a side collision and cannot be avoided, at this time, the seat occupancy monitoring sensor determines whether there is a passenger riding on the seat away from the collision side. At this time, in order to prevent collision injury between double passengers, the collision sensor determines whether to burst the far end airbag according to whether the collision strength reaches the ignition threshold of the safety airbag. When determining to burst the far end airbag, the corresponding target airbag generator is triggered to burst according to the ignition signal.

[0064] In an embodiment, the step of generating a corresponding ignition signal based on the airbag ignition strategy and triggering the corresponding target airbag inflator to burst according to the ignition signal comprises:

[0065] When the airbag ignition strategy is a large body airbag ignition strategy, a distal end ignition signal is generated;

[0066] The distal end ignition signal is transmitted to the distal end airbag inflator to trigger the distal end airbag inflator to burst.

[0067] In a specific implementation, when the airbag ignition strategy is a large body airbag ignition strategy, a distal end ignition signal is generated, and when the distal end airbag inflator of the distal end seat is triggered to burst according to the distal end ignition signal, specifically, the ignition signal is transmitted to an electronic control unit, and the electronic control unit transmits the ignition signal to the airbag inflator of the distal end airbag, so that the distal end airbag inflator of the distal end seat bursts. If it is judged that the near collision side is a large body occupant (50% and above), the distal end airbag on the distal end seat is controlled to burst, as shown in Figure 3 , to ensure that the occupant has sufficient moving space into the vehicle when subjected to the intrusion of the vehicle outside collision, and will not increase the injury to the occupant in the side collision due to excessive extrusion of the distal end airbag.

[0068] In an embodiment, the step of generating a corresponding ignition signal based on the airbag ignition strategy and triggering the corresponding target airbag inflator to burst according to the ignition signal comprises:

[0069] When the airbag ignition strategy is a small body airbag ignition strategy, a proximal end ignition signal is generated;

[0070] The proximal end ignition signal is transmitted to the proximal end airbag inflator to trigger the proximal end airbag inflator to burst.

[0071] In a specific implementation, when the airbag ignition strategy is a small body airbag ignition strategy, a proximal end ignition signal is generated, and when the distal end airbag inflator of the proximal end seat is triggered to burst according to the ignition signal, specifically, the ignition signal is transmitted to an electronic control unit, and the electronic control unit transmits the ignition signal to the airbag inflator of the proximal end airbag, so that the distal end airbag inflator of the proximal end seat bursts. As shown in Figure 4 , Figure 5 Small body personnel have sufficient moving space into the vehicle when subjected to the intrusion of the vehicle outside collision due to their small body size and far distance from the distal end airbag, and the distal end airbag on the proximal end seat is triggered to burst at this time to timely protect the occupant and prevent the occupant from being injured by the collision from the distal end side occupant.

[0072] The embodiment provides a remote airbag ignition control method, which comprises the following steps: acquiring vehicle sensor information, determining a passenger type and a passenger riding state of a remote point according to the vehicle sensor information; acquiring real-time driving data, determining a collision point when it is determined that there is a side collision risk according to the real-time driving data, and determining an airbag ignition strategy based on the collision point, the passenger type and the passenger riding state of the remote point; generating a corresponding ignition signal based on the airbag ignition strategy, triggering a corresponding target airbag inflator to explode according to the ignition signal, and adaptively selecting a corresponding remote airbag ignition according to different working conditions and passenger conditions, so that the harm to the passenger in a side collision is reduced.

[0073] It should be noted that the above examples are only used for understanding the present application and do not constitute a limitation on the remote airbag ignition control method of the present application, and more forms of simple transformation based on the technical concept are within the protection scope of the present application.

[0074] The present application also provides a safety airbag, which is installed inside a main driver seat and a co-driver seat respectively, wherein a safety airbag close to a collision point is a proximal airbag, the proximal airbag comprises a proximal airbag inflator, a safety airbag far from the collision point is a remote airbag, the remote airbag comprises a remote airbag inflator, the proximal airbag and the remote airbag are respectively installed on the side of the corresponding seat, the side of the seat provides support for the proximal airbag and the remote airbag, and the remote airbag ignition control method as described in the above embodiment is implemented. Figure 6 As shown in the figure, since the exploded remote airbag is installed on the remote side seat, the seat side is used as support after the airbag is deployed, the support area is large and the structure is stable, the bending resistance of the airbag when subjected to lateral impact is improved, and stable support is provided for the passenger after the airbag is deployed.
