Description

Technical Field

[0001] The present application relates to the field of vehicle safety technology, and in particular to a method, device, equipment, and computer-readable storage medium for adaptive control of a restraint system. Background Art

[0002] The airbag system is an occupant protection system. In a frontal collision that meets the airbag deployment conditions, the driver and passenger airbags, when properly deployed, can effectively protect the occupant's head, chest, and abdomen. The passenger airbag is typically installed inside the dashboard. When a vehicle is involved in an accident, the acceleration sensor transmits the collision signal to the airbag controller, which initiates the firing command. The inflator rapidly releases gas into the passenger airbag, creating a full air pocket between the occupant and the vehicle's interior, isolating the occupant from direct contact with the interior and minimizing any impact damage.

[0003] Traditional passenger restraint systems are developed for standard seating conditions. Existing airbag deployment methods rely on single parameters, such as acceleration thresholds or pressure variables, to determine deployment timing and stiffness. Some current adaptive airbag control systems account for variations in occupant size and seat position, adjusting the timing and stiffness of airbag deployment. However, when occupants are in critical situations, the massive impact of an airbag deployment can fail to protect them and can even cause additional harm. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0035] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0036] In a first aspect, an embodiment of the present application provides an adaptive control method for a restraint system.

[0037] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the adaptive control method for the constraint system of this application. Figure 1 As shown in Figure 2, the adaptive control method of the constraint system includes:

[0038] Step S10: When it is determined based on the received pre-collision signal that the duration of the vehicle collision is greater than a first preset duration, detection information from a preset sensor is obtained, and when it is determined based on the detection information that the vehicle is in an unstable state, a warning message is sent to the occupants to remind them to correct the unstable state of the vehicle;

[0039] Exemplarily, a vehicle pre-collision signal is received. This pre-collision signal is issued when a collision is predicted to occur within a predetermined duration. The predicted duration is compared with a first preset duration of 3000ms. When the duration of the pre-collision signal exceeds the first preset duration of 3000ms, detection information from preset sensors is acquired. The preset sensors include a pressure sensor, a camera sensor, an infrared temperature sensor, a seat-mounted sensor, and a seatbelt recognition sensor. By acquiring the detection information from the preset sensors, a determination is made as to whether the vehicle is in an unstable state based on the detection information. If the vehicle is determined to be in an unstable state, a warning message is transmitted to alert the occupants to correct the vehicle's unstable state.

[0040] Specifically, when it is determined based on the detection information that the vehicle is in an unstable state, a warning message is sent to remind the occupants to correct the unstable state of the vehicle, including: if the detection information shows that the pressure value within the first preset position range is greater than or equal to the preset pressure value, and there is an object, the upper surface of the IP dashboard is covered by an object, the occupant posture is a preset posture, the seat back angle is greater than the preset angle, and the occupant is not wearing a seat belt, then it is determined that the vehicle is in an unstable state; and a warning message is sent to remind the occupants to correct the unstable state of the vehicle.

[0041] Exemplarily, a pressure sensor is used to detect a pressure value within a first preset position range. If the pressure value detected within the first preset position range is greater than or equal to the preset pressure value of 5g and an object is present within the first preset position range, the vehicle is determined to be in an unstable state. Alternatively, a camera sensor is used to detect an IP instrument panel. If an object is detected covering the upper surface of the IP instrument panel, the vehicle is determined to be in an unstable state. Alternatively, an infrared temperature sensor is used to detect an occupant. If the occupant's posture is detected to be in a preset posture, the vehicle is determined to be in an unstable state. Alternatively, a seat sensor is used to detect a seat back angle greater than a preset angle of 35 degrees. If the seat belt recognition sensor is used to detect a seat occupant. If the seat belt is not fastened, the vehicle is determined to be in an unstable state. If the vehicle is determined to be in an unstable state, a full-belt wearing warning message and / or an airbag warning message are sent to alert the occupant to correct the vehicle's unstable state.

[0042] Step S20: After sending the warning information, if the unstable state does not change and it is determined that the duration of the current collision of the vehicle reaches a second preset duration, formulating a first control strategy based on the detection information; the second preset duration is less than the first preset duration;

[0043] Exemplarily, after sending the warning information to remind the occupants, the current pre-collision time is compared with the second preset time of 50ms. If the current pre-collision time is greater than the second preset time of 50ms and less than the first preset time of 3000ms, a first control strategy is formulated according to the detection information.

[0044] If it is determined that the detection information is that the pressure value within the first preset position range is greater than or equal to the preset pressure value, and there are objects, the upper surface of the IP instrument panel is covered by objects, and the occupant posture is at least one of the preset postures, then a strategy is formulated to suppress airbag deployment, seat belt pre-tightening, and seat belt deployment; if the detection information is that the seat back angle is greater than the preset angle, then a strategy is formulated for automatic return of the seat angle, pre-tightening of the seat belt, full belt deployment, and airbag deployment; if the detection information is that the occupant is not wearing a seat belt, then a strategy is formulated to suppress seat belt deployment and airbag deployment; if the detection information is that the pressure value within the first preset position range is greater than or equal to the preset pressure value, and there are objects, the upper surface of the IP instrument panel is covered by objects, the occupant posture is the preset posture, the seat back angle is greater than the preset angle, and the occupant is not wearing a seat belt, then a strategy is formulated to suppress airbag deployment, suppress seat belt deployment, and formulate automatic return of the seat angle.

[0045] Step S30: When a collision of the vehicle is detected, an ignition signal is output to the restraint system according to the first control strategy, so that the restraint system executes the first control strategy, wherein the first control strategy is at least one of automatic return of the seat angle, suppression of airbag deployment, suppression of seat belt deployment, seat belt pre-tensioning, seat belt deployment and airbag deployment.

[0046] Exemplarily, after establishing a control strategy, upon detecting a vehicle collision, an ignition signal is output to the restraint system according to a first control strategy, causing the restraint system to execute the control strategy. The control strategy includes automatic seat angle return, inhibiting airbag deployment, inhibiting seatbelt deployment, pre-tensioning seatbelts, deploying seatbelts, and deploying airbags. For example, if the first control strategy includes inhibiting airbag deployment, pre-tensioning seatbelts, and deploying seatbelts, the restraint system executes the strategies of inhibiting airbag deployment, pre-tensioning seatbelts, and deploying seatbelts.

[0047] In this embodiment, when it is determined based on the received pre-collision signal that the duration of the vehicle collision is greater than a first preset duration, detection information of a preset sensor is obtained, and when it is determined based on the detection information that the vehicle is in an unstable state, a warning message is sent to the occupants to remind them to correct the unstable state of the vehicle; after sending the warning message, if the unstable state has not changed and it is determined that the duration of the current collision of the vehicle has reached a second preset duration, a first control strategy is formulated based on the unstable state; the second preset duration is less than the first preset duration; when it is detected that the vehicle has collided, an ignition signal is output to the restraint system according to the first control strategy. The system is configured to enable the restraint system to execute the first control strategy, wherein the first control strategy is at least one of automatic return of the seat angle, suppression of airbag deployment, suppression of seatbelt deployment, seatbelt pretensioning, seatbelt deployment and airbag deployment, which solves the technical problem that the adaptive airbag control system in the related art takes into account the different body shapes and seat positions of the occupants to control the time and stiffness of the airbag deployment, but when the occupants are in certain dangerous working conditions, the huge impact force of the airbag deployment not only fails to provide protection but causes additional harm to the occupants, thereby incorporating the judgment of dangerous working conditions into the system control strategy, improving the accuracy of the deployment algorithm, and avoiding harm to the occupants caused by airbag deployment.

[0048] In one embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the second embodiment of the adaptive control method for the constraint system of this application. Figure 2 As shown, the adaptive control method of the constraint system also includes:

[0049] Step S10: When it is determined based on the received pre-collision signal that the duration of the vehicle collision is greater than a first preset duration, detection information from a preset sensor is obtained, and when it is determined based on the detection information that the vehicle is in an unstable state, a warning message is sent to the occupants to remind them to correct the unstable state of the vehicle;

[0050] Exemplarily, a vehicle pre-collision signal is received. This pre-collision signal is issued when a collision is predicted to occur within a predetermined duration. The predicted duration is compared with a first preset duration of 3000ms. When the duration of the pre-collision signal exceeds the first preset duration of 3000ms, detection information from preset sensors is acquired. The preset sensors include a pressure sensor, a camera sensor, an infrared temperature sensor, a seat-mounted sensor, and a seatbelt recognition sensor. By acquiring the detection information from the preset sensors, a determination is made as to whether the vehicle is in an unstable state based on the detection information. If the vehicle is determined to be in an unstable state, a warning message is transmitted to alert the occupants to correct the vehicle's unstable state.

[0051] Specifically, when it is determined based on the detection information that the vehicle is in an unstable state, a warning message is sent to remind the occupants to correct the unstable state of the vehicle, including: if the detection information shows that the pressure value within the first preset position range is greater than or equal to the preset pressure value, and there is an object, the upper surface of the IP dashboard is covered by an object, the occupant posture is a preset posture, the seat back angle is greater than the preset angle, and the occupant is not wearing a seat belt, then it is determined that the vehicle is in an unstable state; and a warning message is sent to remind the occupants to correct the unstable state of the vehicle.

[0052] Exemplarily, a pressure sensor is used to detect a pressure value within a first preset position range. If the pressure value detected within the first preset position range is greater than or equal to the preset pressure value of 5g and an object is present within the first preset position range, the vehicle is determined to be in an unstable state. Alternatively, a camera sensor is used to detect an IP instrument panel. If an object is detected covering the upper surface of the IP instrument panel, the vehicle is determined to be in an unstable state. Alternatively, an infrared temperature sensor is used to detect an occupant. If the occupant's posture is detected to be in a preset posture, the vehicle is determined to be in an unstable state. Alternatively, a seat is detected by a built-in seat sensor. If the seat back angle is detected to be greater than a preset angle of 35 degrees, the vehicle is determined to be in an unstable state. Alternatively, a seat belt recognition sensor is used to detect a passenger. If the occupant is detected to be unbelted, the vehicle is determined to be in an unstable state. If the vehicle is determined to be in an unstable state, a full-belt wearing warning message and / or an airbag warning message are sent to alert the occupant to correct the vehicle's unstable state.

[0053] Step S40: After sending the warning information, if it is determined that the duration of the current collision of the vehicle reaches a second preset duration, reacquiring detection information and formulating a second control strategy based on the reacquired detection information;

[0054] Exemplarily, if it is detected that after sending the seat belt wearing warning information and / or the airbag warning information, it is determined that the duration of the current collision of the vehicle reaches a second preset duration, the detection information is obtained again; and a second control strategy is formulated based on the recovered detection information, and the recovered detection information is that the pressure value within the first preset position range is greater than or equal to the preset pressure value, and there is at least one of an object, the upper surface of the IP dashboard is covered by an object, and the occupant posture is a preset posture.

[0055] Step S50: When a collision of the vehicle is detected, an ignition signal is output to the restraint system according to the second control strategy, causing the restraint system to execute the second control strategy. The second control strategy is at least one of automatic seat angle return, airbag deployment suppression, seatbelt deployment suppression, seatbelt pretensioning, seatbelt deployment, and airbag deployment. For example, when the second control strategy is airbag deployment suppression, seatbelt pretensioning, and seatbelt deployment suppression, the restraint system executes the strategies of airbag deployment suppression, seatbelt pretensioning, and seatbelt deployment.

[0056] Exemplarily, after formulating a new control strategy, when a vehicle collision is detected, an ignition signal is output to the restraint system according to the second control strategy, so that the restraint system executes the second control strategy, wherein the second control strategy includes at least one of automatic return of the seat angle, suppression of airbag deployment, suppression of seat belt deployment, seat belt pre-tensioning, seat belt deployment and airbag deployment.

[0057] In this embodiment, the second control strategy is formulated by re-acquired detection information, which solves the technical problem that the adaptive airbag control system takes into account the different body shapes and seat positions of the occupants to control the time and stiffness of the airbag detonation, but when the occupants are in certain dangerous conditions, the huge impact force of the airbag detonation not only fails to provide protection but causes additional harm to the occupants. This realizes the incorporation of dangerous condition judgment into the system control strategy, improves the accuracy of the detonation algorithm, and avoids damage to the occupants caused by airbag detonation.
