Technical Field

[0002] The airbag system is an occupant protection system. In a frontal collision that meets the conditions for airbag detonation, the driver's airbag and the front passenger's airbag can effectively protect the occupant's head, chest and abdomen when properly deployed. The front passenger's airbag is generally installed in the dashboard. When a vehicle has an accident, the acceleration sensor transmits the collision signal to the airbag controller to issue an ignition command. The gas generator quickly releases gas into the front passenger's airbag, forming a full air bag between the occupant and the interior parts of the vehicle, isolating the occupant from direct contact with the interior parts, and reducing the damage caused by the collision to the occupant.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, 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 the present application are explained to facilitate those skilled in the art to understand the present application.

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with 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 of the constraint system of the present application. Figure 1 As shown, the adaptive control method of the constraint system includes:

[0038] Step S10: when it is determined according to 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 acquired, and when it is determined according to 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;

[0039] Exemplarily, a pre-collision signal of a vehicle is received, and the pre-collision signal is a pre-collision signal issued when a collision is predicted within the estimated duration of the vehicle. The estimated duration of the vehicle is compared with the first preset duration of 3000ms. When the duration of the pre-collision signal is greater than the first preset duration of 3000ms, the detection information of the preset sensor is obtained. The preset sensor includes a pressure sensor, a camera sensor, an infrared temperature sensor, a seat built-in sensor, and a seat belt recognition sensor. By obtaining the detection information of the preset sensor, it is determined whether the vehicle is in an unstable state based on the detection information. If it is determined 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.

[0040] Specifically, when it is determined according to 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 is 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 is covered with an object, the occupant's posture is a preset posture, the seat back angle is greater than a 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, the pressure sensor is used to detect the first preset position range. If the pressure value detected in the first preset position range is greater than or equal to the preset pressure value 5g, and there is an object in the first preset position range, it is determined that the vehicle is in an unstable state; and / or, the IP board is detected by the camera sensor. If it is detected that there is an object covering the upper surface of the IP, it is determined that the vehicle is in an unstable state; or, the occupant is detected by the infrared temperature sensor. If the occupant posture is detected to be a preset posture, it is determined that the vehicle is in an unstable state; and / or, the seat is detected by the seat built-in sensor. If the seat back angle is detected to be greater than the preset angle of 35 degrees, it is determined that the vehicle is in an unstable state; and / or, the seat member is detected by the seat belt recognition sensor. If it is detected that the occupant is not wearing a seat belt, it is determined that the vehicle is in an unstable state. If it is determined that the vehicle is in an unstable state, a full belt wearing warning information and / or an airbag warning information are sent to remind the occupant to correct the unstable state of the vehicle.

[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, a first control strategy is formulated according to 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 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 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 the control strategy is formulated, 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 control strategy, wherein the control strategy includes automatic return of the seat angle, suppression of airbag deployment, suppression of seat belt deployment, seat belt pretensioning, seat belt deployment and airbag deployment. For example, when the first control strategy is suppression of airbag deployment, seat belt pretensioning and seat belt deployment, the restraint system executes the strategy of suppression of airbag deployment, seat belt pretensioning and seat belt deployment.

[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 the first preset duration, the detection information of the 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 remind the occupants 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 current duration of the vehicle collision 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 constraint according to the first control strategy. The system is provided with a plurality of control strategies, wherein the plurality of control strategies are: a first control strategy for controlling 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 seat belt deployment, seat belt pretensioning, seat belt deployment and airbag deployment, and 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, thereby controlling 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, and realizes 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 the deployment of airbags.

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

[0049] Step S10: when it is determined according to 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 acquired, and when it is determined according to 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;

[0050] Exemplarily, a pre-collision signal of a vehicle is received, and the pre-collision signal is a pre-collision signal issued when a collision is predicted within the estimated duration of the vehicle. The estimated duration of the vehicle is compared with the first preset duration of 3000ms. When the duration of the pre-collision signal is greater than the first preset duration of 3000ms, the detection information of the preset sensor is obtained. The preset sensor includes a pressure sensor, a camera sensor, an infrared temperature sensor, a seat built-in sensor, and a seat belt recognition sensor. By obtaining the detection information of the preset sensor, it is determined whether the vehicle is in an unstable state based on the detection information. If it is determined 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.

[0051] Specifically, when it is determined according to 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 is 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 is covered with an object, the occupant's posture is a preset posture, the seat back angle is greater than a 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, the pressure sensor is used to detect the first preset position range. If the pressure value detected in the first preset position range is greater than or equal to the preset pressure value 5g, and there is an object in the first preset position range, it is determined that the vehicle is in an unstable state; and / or, the IP board is detected by the camera sensor. If it is detected that there is an object covering the upper surface of the IP, it is determined that the vehicle is in an unstable state; or, the occupant is detected by the infrared temperature sensor. If the occupant posture is detected to be a preset posture, it is determined that the vehicle is in an unstable state; and / or, the seat is detected by the seat built-in sensor. If the seat back angle is detected to be greater than the preset angle of 35 degrees, it is determined that the vehicle is in an unstable state; and / or, the seat member is detected by the seat belt recognition sensor. If it is detected that the occupant is not wearing a seat belt, it is determined that the vehicle is in an unstable state. If it is determined that the vehicle is in an unstable state, a full belt wearing warning information and / or an airbag warning information are sent to remind the occupant to correct the unstable state of the vehicle.

[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 according to the reacquired detection information;

[0054] Exemplarily, if it is detected that after sending a seat belt wearing warning message and / or an airbag warning message, it is determined that the duration of the current collision of the vehicle reaches a second preset duration, the detection information is re-acquired; and a second control strategy is formulated based on the re-acquired detection information, and the re-acquired 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 an object, the upper surface of the IP is covered by an object, and the occupant posture is at least one of the preset postures.

[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, so that the restraint system executes the second control strategy, wherein the second control strategy is at least one of automatic return of seat angle, suppression of airbag detonation, suppression of seat belt detonation, seat belt pretension, seat belt detonation and airbag detonation. For example, when the second control strategy is suppression of airbag detonation, seat belt pretension and seat belt detonation, the restraint system executes the strategy of suppression of airbag detonation, seat belt pretension and seat belt detonation.

[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 through the 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 also causes additional harm to the occupants. This realizes incorporating the judgment of dangerous conditions into the system control strategy, improving the accuracy of the detonation algorithm, and avoiding harm to the occupants caused by airbag detonation.
