Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a remote airbag ignition method and device, a computer program, and a readable storage medium. Background Art

[0002] A side collision is a traffic accident with a high frequency and a high number of casualties. The side structure of a car is weak and the energy absorption space is insufficient, making it difficult to control the damage caused to the occupants in the car by a side collision. Previous studies have mostly focused on the proximal occupants in a collision, and relatively few studies have been conducted on distal side collisions, which have not received sufficient attention. Statistics show that MAIS3+ injuries to front-seat occupants over the age of 12 mainly include secondary collisions between the non-collision side occupants and the collision side occupants, as well as secondary collisions between the non-collision side occupants and interior trim such as seats. Vehicle seat belts and seats often do not effectively restrain the lateral movement of the dummy, so it is particularly important to increase the design of configurations such as distal protection airbags to control the degree of occupant excursion. CNCAP (China New Car Assessment Program) 2024 introduced distal occupant protection to evaluate the vehicle safety level, which further promoted the installation of distal airbags in cars.

[0003] However, when the remote airbag is ignited also has a significant impact on the safety of the crew members. It is necessary to judge the ignition of the remote airbag to reduce the adverse effects of the remote airbag itself on the crew members. Summary of the Invention

[0004] The present application provides a remote airbag ignition method and device, a computer program and a readable storage medium to solve the problem that the current remote airbag ignition moment affects the safety of the occupants.

[0005] In a first aspect, the present application provides a method for remote airbag ignition in a side collision, which is applied to a vehicle equipped with a remote airbag between the driver and the passenger, comprising the following steps:

[0006] Get the side collision position and collision parameters;

[0007] Determine the remote airbag deployment strategy based on the side impact location, collision parameters, and passenger seat conditions;

[0008] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side collision locations and / or different passenger seating conditions.

[0009] In this application, whether to deploy the remote airbag is determined based on the side impact position, collision parameters and the passenger's riding conditions. That is, the remote airbag and the side airbag are not controlled to deploy simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on the safety of the occupants.

[0010] In some embodiments, the remote airbag can be installed only on the driver's side, only on the passenger side, or on both the driver's and passenger sides. Different car brands and models have different remote airbag installation locations based on practical needs. Depending on the remote airbag installation location, different remote airbag deployment strategies can be selected to provide protection for the driver and passenger seats in different situations.

[0011] In some embodiments, the remote airbag deployment strategy includes at least two of: simultaneous deployment of the remote airbag and side airbags, non-deployment of the remote airbag, or deployment of the remote airbag after the side airbags. For a given vehicle model, the remote airbag installation location is fixed and unique. Therefore, for a given vehicle model, at least two different remote airbag deployment strategies are available based on the side impact location, collision parameters, and passenger seat occupancy, to provide protection for the driver and passenger seats in different situations.

[0012] In some embodiments, the collision parameter includes at least one of collision acceleration and door pressure, which is used to determine whether a remote airbag deployment parameter threshold has been reached. During a collision, the most noticeable change in vehicle acceleration is the change in vehicle acceleration. Furthermore, the impact of the collision on occupants can be reflected through door pressure. Using at least one of the collision acceleration and door pressure can more accurately reflect the impact and pressure felt by occupants during a collision, thereby improving the accuracy of remote airbag deployment strategies.

[0013] In some embodiments, if the remote airbag of the side-impact vehicle is only provided on the driver's side, determining the remote airbag deployment strategy based on the side-impact location, collision parameters, and passenger seat condition includes:

[0014] If the side impact occurs on the passenger side and the remote airbag deployment threshold is reached based on the collision parameters, the remote airbag and the side airbag are deployed simultaneously; or

[0015] If the side collision occurs on the driver's side, and the remote airbag deployment parameter threshold is reached based on the collision parameters, and there is no one on the passenger side, the remote airbag will not be deployed; or,

[0016] If the side collision occurs on the driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the passenger seat, the remote airbag will be controlled and then the side airbag will be deployed.

[0017] If a vehicle with a side impact is only equipped with a remote airbag on the driver's side, and the collision occurs on the passenger side, and the collision parameters determine that the remote airbag deployment threshold has been reached, the driver of the vehicle will quickly fall toward the passenger side due to inertia. To protect the driver's head, the remote and side airbags are deployed simultaneously. This allows the driver's head to be supported in a side impact away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is another passenger in the passenger seat, the remote and side airbags are deployed simultaneously.

[0018] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the main driver's occupant will not fall to the front passenger side, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the remote airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0019] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the front passenger seat, under the action of inertia, the front passenger seat occupant will quickly fall to the main driver's side. At this time, the main purpose of the remote airbag is to protect the front passenger seat occupant. While protecting the front passenger seat occupant, it is also necessary to reduce the squeezing of the main driver seat occupant when the remote airbag and the side airbag are detonated at the same time, and reduce the impact of the remote airbag's own detonation on the main driver. Therefore, the remote airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the remote airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the remote airbag detonation on the occupants.

[0020] In some embodiments, if the remote airbag of the side-impact vehicle is only located on the passenger side, determining the remote airbag deployment strategy based on the side-impact location, collision parameters, and passenger seat condition includes:

[0021] If the side impact occurs on the passenger side and the remote airbag deployment threshold is reached based on the collision parameters, the remote airbag and the side airbag are deployed simultaneously; or

[0022] If the side collision occurs on the driver's side, and the collision parameters determine that the remote airbag deployment parameter threshold has been reached, and there is someone sitting on the passenger seat, the remote airbag and the side airbag will be deployed simultaneously; or

[0023] If the side collision occurs on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger side, the remote airbag will not be deployed.

[0024] If a vehicle involved in a side collision has its remote airbag only installed on the passenger side, and the collision occurs on the passenger side, and the collision parameters determine that the remote airbag deployment threshold has been reached, the driver in the main passenger seat will quickly fall toward the passenger side due to inertia. To protect the driver's head, the remote and side airbags are controlled to deploy simultaneously. This allows the driver's head to be supported in a side collision on the side away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is another passenger in the passenger seat, the remote and side airbags are controlled to deploy simultaneously.

[0025] When the distal airbag of a side-collision vehicle is only set on the passenger side, the side collision position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the passenger seat, the passenger seat will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the passenger seat. The distal airbag is only set on the passenger side, and its detonation will not affect the main driver's side. Therefore, controlling the distal airbag to be set only on the passenger side can better protect the passenger seat.

[0026] When the distal airbag of a side-collision vehicle is only set on the passenger side, the side collision position is on the main driver's side, and the distal airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the passenger seat, since there is no passenger in the passenger seat and the main driver's seat occupants will not fall towards the passenger seat, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the distal airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0027] In some embodiments, if the remote airbags of the side-impact vehicle are both located on the driver's side and the passenger's side, determining the remote airbag deployment strategy based on the side-impact location, collision parameters, and the passenger's riding condition includes:

[0028] If the side impact occurs on the passenger side and the remote airbag deployment threshold is reached based on the collision parameters, the remote airbag and the side airbag are deployed simultaneously; or

[0029] If the side collision occurs on the driver's side, and the remote airbag deployment parameter threshold is reached based on the collision parameters, and there is no one on the passenger side, the remote airbag will not be deployed; or,

[0030] If the side collision occurs on the driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the passenger seat, the remote airbag will be controlled and then the side airbag will be deployed.

[0031] When a vehicle involved in a side collision has its distal airbags deployed on both the driver's and passenger's sides, and the collision occurs on the passenger side, and the collision parameters determine that the distal airbag deployment threshold has been reached, the driver of the vehicle will rapidly fall toward the passenger side due to inertia. To protect the driver's head, the distal airbag and the side airbag are deployed simultaneously. This allows the driver's head to be supported in a side collision on the side away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is a passenger in the passenger seat, the distal airbag and the side airbag are deployed simultaneously.

[0032] When the remote airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the driver's seat occupants will not fall towards the front passenger seat, the side airbags are sufficient to provide protection for the driver. Therefore, there is no need to deploy the remote airbags, and the driver can also be protected, while reducing the use of side airbags and reducing costs.

[0033] When the distal airbags of a side-collision vehicle are set on both the driver's side and the front passenger side, the side collision position is on the driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger side, under the action of inertia, the front passenger occupant will quickly fall to the driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger occupant. While protecting the front passenger, it is also necessary to reduce the squeezing of the main driver when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the main driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and occupants and minimizes the impact of the distal airbag detonation on the occupants.

[0034] In a second aspect, the present application provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application are implemented.

[0035] In a third aspect, the present application provides a computer program product, comprising a computer program, which, when executed by a processor, implements the steps of the remote airbag ignition method in a side collision described in the first aspect of the present application.

[0036] In a fourth aspect, the present application provides a remote airbag ignition device for a side collision, comprising:

[0037] An acquisition unit, used to obtain side collision position and collision parameters;

[0038] The control unit is used to determine the deployment strategy of the remote airbag based on the side impact position, collision parameters and the passenger seat condition. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of this application without making any creative efforts shall fall within the scope of protection of this application.

[0046] A side collision is a traffic accident with a high frequency and a high number of casualties. The side structure of a car is weak and the energy absorption space is insufficient, making it difficult to control the damage caused to the occupants in the car by a side collision. Previous studies have mostly focused on the proximal occupants in a collision, and relatively few studies have been conducted on distal side collisions, which have not received sufficient attention. Statistics show that MAIS3+ injuries to front-seat occupants over the age of 12 mainly include secondary collisions between the non-collision side occupants and the collision side occupants, as well as secondary collisions between the non-collision side occupants and interior trim such as seats. Vehicle seat belts and seats often do not effectively restrain the lateral movement of the dummy, so it is particularly important to increase the design of configurations such as distal protection airbags to control the degree of occupant excursion. CNCAP (China New Car Assessment Program) 2024 introduced distal occupant protection to evaluate the vehicle safety level, which further promoted the installation of distal airbags in cars.

[0047] Remote airbags, also known as inboard or center airbags, are primarily installed between the front occupants of a vehicle. They can be installed on the driver's side, the front passenger side, or both. In the event of a side impact, they prevent the front occupants from colliding with each other and causing injury. Remote airbags typically feature two large cavities, one for the head and one for the chest, effectively absorbing impact energy and providing support, thereby protecting the occupant's head and upper body from serious injury.

[0048] However, when the remote airbag is ignited also has a significant impact on the safety of the crew members. It is necessary to judge the ignition of the remote airbag to reduce the adverse effects of the remote airbag itself on the crew members.

[0049] In view of this, the present application provides a remote airbag ignition method and device, a computer program and a readable storage medium to solve the problem that the existing remote airbag ignition moment affects the safety of the occupants.

[0050] First, as Figure 1 As shown, in a first embodiment of the present application, the present application provides a method for remote airbag ignition in a side collision, which is applied to a vehicle with a remote airbag between the driver and the passenger, comprising the following steps:

[0051] S10, obtaining the side collision position and collision parameters;

[0052] S20: Determine a remote airbag deployment strategy based on the side impact location, collision parameters, and passenger seat condition;

[0053] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side collision locations and / or different passenger seating conditions.

[0054] In this application, whether to deploy the remote airbag is determined based on the side impact position, collision parameters and the passenger's riding conditions. That is, the remote airbag and the side airbag are not controlled to deploy simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on the safety of the occupants.

[0055] It should be noted that the driver's side and the passenger side of the vehicle can be selected according to the laws and regulations of the actual use area. For example, in some areas, the main driver's side is on the left side of the vehicle's travel direction, and the passenger side is on the right side of the vehicle's travel direction. In some areas, the main driver's side is on the right side of the vehicle's travel direction, and the passenger side is on the left side of the vehicle's travel direction.

[0056] It should be noted that the collision position is determined based on the direction of the vehicle's lateral acceleration during a side collision. That is, no matter whether the collision occurs at the front, body, or rear of the vehicle, as long as the acceleration direction is measured by the acceleration sensor, it can be determined whether the collision position is on the driver's side or the co-driver's side. If the vehicle's lateral acceleration direction is toward the driver's side, the collision position occurs on the co-driver's side; if the vehicle's lateral acceleration direction is toward the co-driver's side, the collision position occurs on the driver's side. It should be noted that the vehicle's lateral acceleration takes a positive value. Judging the collision position by the direction of acceleration is more sensitive and concise. It should be noted that since the collision acceleration needs to reflect the force exerted on the occupants during the collision, the acceleration sensor is usually located at the occupant's seat position so that the measured acceleration is more consistent with the member's perception.

[0057] In actual operation, the acceleration sensors on the main driver's side and the front passenger side can be used to detect the side whose acceleration reaches the preset value first within a set time, for example, within 20ms, which is the side where the collision occurred. This is because when a collision occurs, it takes a certain amount of time for the acceleration to be transmitted from the collision side to the non-collision side. Therefore, the acceleration sensor on the collision side will detect the signal before the acceleration sensor on the non-collision side, and will also detect that the acceleration reaches the preset value before the acceleration sensor on the non-collision side.

[0058] In conjunction with the first aspect, in a second embodiment provided herein, the remote airbag can be installed only on the driver's side, only on the passenger side, or on both the driver's and passenger sides. Different car brands and models have different remote airbag installation locations due to practical needs. Depending on the remote airbag installation location, different remote airbag deployment strategies can be selected to provide protection for both the driver and passenger seats in different situations.

[0059] In conjunction with the first aspect, in a third embodiment provided herein, the remote airbag deployment strategy includes at least two of the following: simultaneous deployment of the remote airbag and side airbags, non-deployment of the remote airbag, or deployment of the remote airbag after the side airbag. For a given vehicle model, the remote airbag installation location is fixed and unique. Therefore, for a given vehicle model, at least two different remote airbag deployment strategies are available based on the side impact location, collision parameters, and passenger seat occupancy, to provide protection for the driver and passenger seats in different situations. It should be noted that the side airbags in this application refer to the outer airbags. Specifically, the side airbag on the driver's side refers to the side airbag on the driver's side away from the passenger seat; the side airbag on the passenger side refers to the side airbag on the passenger seat away from the driver's side. It should be noted that airbag deployment results in the release of energy. When the vehicle is involved in a low-intensity collision, airbag deployment poses a greater risk than the vehicle impact.

[0060] In conjunction with the first aspect, in a fourth embodiment provided herein, the collision parameter includes at least one of collision acceleration and door pressure, and the collision parameter is used to determine whether the remote airbag deployment parameter threshold has been reached. During a collision, the most noticeable change in vehicle acceleration is the change in vehicle acceleration. Furthermore, the impact of the collision on occupants can be reflected by door pressure. Using at least one of the collision acceleration and door pressure can more accurately reflect the impact and pressure felt by occupants during a collision, thereby improving the accuracy of the remote airbag deployment strategy.

[0061] By determining whether the collision acceleration reaches the collision acceleration threshold for remote airbag deployment, it is possible to identify whether the collision intensity reaches a level that requires remote airbag deployment, thereby improving the accuracy of the remote airbag deployment strategy. It should be noted that the collision acceleration threshold for remote airbag deployment can be the detection of 5 to 10 g-force acceleration peaks within 10 milliseconds of the collision, which is a prerequisite for airbag deployment, also known as the airbag deployment parameter threshold. In some embodiments of the present application, the accuracy of the remote airbag deployment strategy can be improved by first determining whether the collision acceleration reaches the collision acceleration threshold for remote airbag deployment, and then determining whether the door pressure values ​​before and after the collision reach the door pressure threshold for remote airbag deployment. It should be noted that the door pressure threshold for remote airbag deployment can be in the range of 10 to 14 kPa. That is, after a collision, depending on the vehicle model, as long as the detected door pressure reaches a set pressure value between 10 and 14 kPa, the remote airbag deployment condition is determined to have been met.

[0062] Combined with the first aspect, such as Figure 2 As shown, in the fifth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only provided on the main driver's side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger seat condition includes:

[0063] S201. If the side collision location is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously.

[0064] If a vehicle with a side impact is only equipped with a remote airbag on the driver's side, and the collision occurs on the passenger side, and the collision parameters determine that the remote airbag deployment threshold has been reached, the driver of the vehicle will quickly fall toward the passenger side due to inertia. To protect the driver's head, the remote and side airbags are deployed simultaneously. This allows the driver's head to be supported in a side impact away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is another passenger in the passenger seat, the remote and side airbags are deployed simultaneously.

[0065] Combined with the first aspect, such as Figure 3 As shown, in the sixth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only provided on the main driver's side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger seat condition includes:

[0066] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger side, control the remote airbag not to deploy.

[0067] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the main driver's occupant will not fall to the front passenger side, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the remote airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0068] Combined with the first aspect, such as Figure 4 As shown, in the seventh embodiment provided in the present application, if the remote airbag of the side impact vehicle is only provided on the main driver's side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger seat condition includes:

[0069] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag is controlled and deployed after the side airbag.

[0070] When the remote airbag of a side-impact vehicle is only set on the main driver's side, if the side impact position is on the main driver's side, and the remote airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the front passenger seat, under the action of inertia, the front passenger seat occupant will quickly fall to the main driver's side. At this time, the main purpose of the remote airbag is to protect the front passenger seat occupant. While protecting the front passenger seat occupant, it is also necessary to reduce the squeezing of the main driver seat occupant when the remote airbag and the side airbag are detonated at the same time, and reduce the impact of the remote airbag's own detonation on the main driver. Therefore, the remote airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the remote airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and passengers and minimizes the impact of the remote airbag detonation on the occupants.

[0071] Combined with the first aspect, such as Figure 2 As shown, in the eighth embodiment provided by the present application, if the remote airbag of the side impact vehicle is only provided on the passenger side, the strategy for determining the remote airbag deployment based on the side impact position, collision parameters and passenger seat condition includes:

[0072] S201. If the side collision location is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously.

[0073] If a vehicle involved in a side collision has its remote airbag only installed on the passenger side, and the collision occurs on the passenger side, and the collision parameters determine that the remote airbag deployment threshold has been reached, the driver in the main passenger seat will quickly fall toward the passenger side due to inertia. To protect the driver's head, the remote and side airbags are controlled to deploy simultaneously. This allows the driver's head to be supported in a side collision on the side away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is another passenger in the passenger seat, the remote and side airbags are controlled to deploy simultaneously.

[0074] Combined with the first aspect, such as Figure 5 As shown, in the ninth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only provided on the passenger side, the strategy for determining the remote airbag deployment based on the side impact position, collision parameters and passenger seat condition includes:

[0075] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag and the side airbag are controlled to deploy simultaneously.

[0076] When the distal airbag of a side-collision vehicle is only set on the passenger side, the side collision position is on the main driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting in the passenger seat, the passenger seat will quickly fall to the main driver's side. At this time, the main purpose of the distal airbag is to protect the passenger seat. The distal airbag is only set on the passenger side, and its detonation will not affect the main driver's side. Therefore, controlling the distal airbag to be set only on the passenger side can better protect the passenger seat.

[0077] Combined with the first aspect, such as Figure 3 As shown, in the tenth embodiment provided in the present application, if the remote airbag of the side impact vehicle is only provided on the passenger side, the strategy for determining the remote airbag deployment based on the side impact position, collision parameters, and passenger seat condition includes:

[0078] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger side, control the remote airbag not to deploy.

[0079] When the distal airbag of a side-collision vehicle is only set on the passenger side, the side collision position is on the main driver's side, and the distal airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the passenger seat, since there is no passenger in the passenger seat and the main driver's seat occupants will not fall towards the passenger seat, the side airbag is sufficient to provide protection for the main driver. Therefore, there is no need to deploy the distal airbag, and the main driver can also be protected, while reducing the use of side airbags and reducing costs.

[0080] Combined with the first aspect, such as Figure 2 As shown, in the eleventh embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the driver's side and the passenger side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger's riding condition includes:

[0081] S201. If the side collision location is on the passenger side and the remote airbag deployment parameter threshold is reached according to the collision parameters, the remote airbag and the side airbag are controlled to deploy simultaneously.

[0082] When a vehicle involved in a side collision has its distal airbags deployed on both the driver's and passenger's sides, and the collision occurs on the passenger side, and the collision parameters determine that the distal airbag deployment threshold has been reached, the driver of the vehicle will rapidly fall toward the passenger side due to inertia. To protect the driver's head, the distal airbag and the side airbag are deployed simultaneously. This allows the driver's head to be supported in a side collision on the side away from the driver, minimizing head displacement and, consequently, reducing neck injury. In other words, regardless of whether there is a passenger in the passenger seat, the distal airbag and the side airbag are deployed simultaneously.

[0083] Combined with the first aspect, such as Figure 3 As shown, in the twelfth embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the driver's side and the passenger's side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger's riding condition includes:

[0084] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one on the front passenger side, control the remote airbag not to deploy.

[0085] When the remote airbags of a side-impact vehicle are set on both the driver's side and the front passenger side, the side impact position is on the driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is no one in the front passenger seat, since there is no passenger in the front passenger seat and the driver's seat occupants will not fall towards the front passenger seat, the side airbags are sufficient to provide protection for the driver. Therefore, there is no need to deploy the remote airbags, and the driver can also be protected, while reducing the use of side airbags and reducing costs.

[0086] Combined with the first aspect, such as Figure 4 As shown, in the thirteenth embodiment provided in the present application, if the remote airbags of the side impact vehicle are arranged on both the driver's side and the passenger's side, the remote airbag deployment strategy determined according to the side impact position, collision parameters and the passenger's riding condition includes:

[0087] S201. If the side collision location is on the main driver's side, and the remote airbag deployment parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger seat, the remote airbag is controlled and deployed after the side airbag.

[0088] When the distal airbags of a side-collision vehicle are set on both the driver's side and the front passenger side, the side collision position is on the driver's side, and the distal airbag detonation parameter threshold is reached according to the collision parameters, and there is someone sitting on the front passenger side, under the action of inertia, the front passenger occupant will quickly fall to the driver's side. At this time, the main purpose of the distal airbag is to protect the front passenger occupant. While protecting the front passenger, it is also necessary to reduce the squeezing of the main driver when the distal airbag and the side airbag are detonated at the same time, and reduce the impact of the distal airbag's own detonation on the main driver. Therefore, the distal airbag is controlled to detonate after the side airbag, that is, the side airbag is detonated first, and then the distal airbag is detonated. The time interval between the two can be 20ms, which minimizes the damage to the driver and occupants and minimizes the impact of the distal airbag detonation on the occupants.

[0089] In a second aspect, the present application provides a computer-readable storage medium having a computer program stored thereon. When executed by a processor, the computer program implements the steps of the method for remote airbag deployment in a side collision described in the first aspect of the present application. The computer-readable storage medium includes all technical solutions of the method for remote airbag deployment in a side collision, and thus has all the beneficial effects of the method, which are not further detailed herein.

[0090] In a third aspect, the present application provides a computer program product comprising a computer program. When executed by a processor, the computer program implements the steps of the method for remote airbag deployment in a side collision described in the first aspect of the present application. The computer program product incorporates all the technical solutions of the method for remote airbag deployment in a side collision, and thus possesses all the beneficial effects of the method. This application will not further elaborate on these details.

[0091] Fourthly, Figure 6 As shown, the present application provides a remote airbag ignition device in a side collision, comprising:

[0092] An acquisition unit, used to obtain side collision position and collision parameters;

[0093] A control unit is used to determine the remote airbag deployment strategy based on the side impact location, collision parameters, and passenger seat conditions;

[0094] Among them, there are at least two situations in which the remote airbag has different detonation strategies under different side collision locations and / or different passenger seating conditions.

[0095] In summary, whether to deploy the remote airbag is determined based on the side impact location, collision parameters and the passenger's riding conditions. In other words, the remote airbag and the side airbag are not controlled to deploy simultaneously under all circumstances. This can balance the protection of the remote airbag to the occupants, while reducing the squeezing of the occupants caused by the deployment of the remote airbag, thereby reducing the impact on occupant safety.
