Abstract
Description
Technical Field
[0001] The present application relates to the technical field of airbag control, and in particular to an airbag system, an airbag control method, an electronic device, a computer-readable storage medium, and a vehicle. Background Art
[0002] In recent years, airbag systems have been widely adopted as a passive safety technology in vehicles. When a vehicle collides, the airbag rapidly inflates and deploys, cushioning the user's forward momentum and reducing the risk of injury. For example, in a head-on collision, the driver's airbag in the steering wheel inflates and deploys within a very short time, protecting the driver's head and chest. However, in some operating conditions, such as off-road driving, the vehicle may experience a minor collision or rollover due to factors such as sloping down a slope or overcoming an obstacle. In these situations, the user may not want the vehicle's airbag to deploy. Currently, the collision and rollover ignition functions of vehicles are prone to false triggering. Summary of the Invention

DETAILED DESCRIPTION
[0079] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. Furthermore, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are intended only to explain the embodiments of the present application and are not to be construed as limiting the present application.
[0080] See also Figure 1 and Figure 2 In one embodiment of the present application, an airbag system 400 is provided. The airbag system 400 is applied to a vehicle 1000 and includes an airbag assembly 300 and an airbag control device 200 for controlling the airbag assembly 300. The control strategy of the airbag assembly 300 includes a first strategy and a second strategy. In the second strategy, the second ignition threshold of the airbag assembly 300 is higher than the first ignition threshold of the airbag assembly 300 in the first strategy.
[0081] In the airbag system 400 of the embodiment of the present application, the control strategy of the airbag assembly 300 includes a first strategy and a second strategy. The second ignition threshold of the airbag assembly 300 under the second strategy is higher than the first ignition threshold of the airbag assembly 300 under the first strategy. This reduces the risk of accidental triggering of the crash ignition function and the rollover ignition function in off-road conditions.
[0082] Specifically, vehicle 1000 includes an airbag system 400, which includes an airbag assembly 300 and an airbag control unit 200. Airbag control unit 200 may be a central airbag sensor assembly (Supplemental Restraint System Electronic Control Unit, SRS ECU), which controls airbag assembly 300. Airbag assembly 300 includes an airbag actuator and multiple airbags. The airbag actuator controls the firing of all airbags, causing the corresponding airbags to deploy.
[0083] The control strategy of the airbag assembly 300 includes a first strategy and a second strategy. The control strategy refers to the strategy for controlling airbag deployment. The second ignition threshold of the airbag assembly 300 under the second strategy is higher than the first ignition threshold of the airbag assembly 300 under the first strategy. The ignition threshold refers to the threshold for igniting and deploying the airbag.
[0084] In one example, the airbag system 400 further includes a sensor for detecting impact force and obtaining a detection result. The ignition threshold is also a threshold corresponding to the impact force. When the control strategy of the airbag assembly 300 is the first strategy, if the detection result is less than or equal to the first ignition threshold, the airbag does not deploy; if the detection result is greater than the first ignition threshold, the airbag is controlled to deploy. When the control strategy of the airbag assembly 300 is the second strategy, if the detection result is less than or equal to the first ignition threshold, the airbag does not deploy; if the detection result is greater than the second ignition threshold, the airbag is controlled to deploy.
[0085] It is understood that the impact force of the vehicle 1000 varies under different operating conditions. For example, in off-road conditions, when the vehicle 1000 rushes up a slope or over an obstacle, it will have a higher instantaneous speed, and the impact force is significantly greater than the impact force under normal driving conditions.
[0086] If the same control strategy is used for different working conditions, it may result in the collision ignition function and the rollover ignition function not being triggered when the vehicle 1000 collides or rolls over under normal driving conditions, and the airbag cannot be deployed in time; it may also result in the collision ignition function and the rollover ignition function being mistakenly triggered under off-road conditions, causing the airbag to deploy.
[0087] Therefore, the control strategy of the airbag assembly 300 is divided into a first strategy and a second strategy, with different control strategies corresponding to different operating conditions. For example, the first strategy may be the control strategy for vehicle 1000 under normal driving conditions, while the second strategy may be the control strategy for vehicle 1000 under off-road conditions. The second ignition threshold corresponding to off-road conditions is higher than the first ignition threshold corresponding to normal driving conditions. In off-road conditions, the airbag assembly 300 is inhibited to a certain extent to prevent false triggering.
[0088] In this way, under normal driving conditions, when the vehicle 1000 collides or rolls over, the collision ignition function and the rollover ignition function can be triggered in time to deploy the airbags; under off-road conditions, the collision ignition function and the rollover ignition function will not be mistakenly triggered due to rushing down a slope or going over an obstacle.
[0089] See also Figure 1 In some embodiments, the airbag control device 200 is configured to receive an adjustment signal for adjusting the control strategy, so as to adjust the control strategy to the first strategy or the second strategy.
[0090] Specifically, the airbag control device 200 is used to adjust the control strategy of the airbag assembly 300. After receiving the adjustment signal, the airbag control device 200 may adjust the control strategy to the first strategy or the second strategy based on the adjustment signal.
[0091] It should be noted that the airbag control device 200 can directly adjust the control strategy to the first strategy or the second strategy based on the adjustment signal; or, the airbag control device 200 can also further process the adjustment signal and then adjust the control strategy to the first strategy or the second strategy according to the processing result.
[0092] See also Figure 1 and Figure 2 In some embodiments, the signal source of the adjustment signal includes: a user's manual adjustment operation; and / or a user's voice input operation; and / or the vehicle 1000's automatic recognition result of the environment.
[0093] Specifically, the adjustment signal can be generated based on a user's operation. For example, the adjustment signal can be generated by a manual adjustment operation by the user. An operation button can be provided in the vehicle 1000. When the user wishes to adjust the control strategy of the airbag assembly 300, the user can press the button, and the airbag control device 200 can receive the adjustment signal.
[0094] For another example, the adjustment signal can originate from a user's voice input. A microphone can be installed in vehicle 1000 to capture user audio data. When the user wishes to adjust the control strategy of airbag assembly 300, they can simply speak the corresponding command. The microphone captures the audio data, and the airbag control device 200 receives the adjustment signal. This allows the user to proactively adjust the control strategy of airbag assembly 300 as needed, better meeting their needs.
[0095] The adjustment signal may also be generated based on the result of the vehicle 1000 automatically identifying the environment.
[0096] See also Figure 1 and Figure 2 In some embodiments, the airbag system 400 includes an identification component configured to identify the environment in which the vehicle 1000 is located. When the identification component identifies that the vehicle 1000 is in a normal operating condition, the identification component sends an adjustment signal to the airbag control device 200 to adjust the control strategy to a first strategy. When the identification component identifies that the vehicle 1000 is in an off-road operating condition, the identification component sends an adjustment signal to the airbag control device 200 to adjust the control strategy to a second strategy.
[0097] Specifically, an identification component can be provided in the airbag system 400 for environmental detection and identification. The identification component can include any one or more sensors selected from environmental perception sensors and visual sensors. Environmental perception sensors include barometers and acoustic sensors. The barometer can be used to detect air pressure. In off-road conditions, the vehicle 1000 may climb a steep slope, and the barometer can detect significant changes in air pressure. The acoustic sensor can be used to detect the noise spectrum between the tires of the vehicle 1000 and the ground. The road surface under off-road conditions is significantly different from the road surface under normal conditions, and the noise spectrum between the tires and the ground will also exhibit different characteristics.
[0098] Visual sensors include cameras and radars. Cameras can be used to identify road surface types and obstacles. For example, cameras can identify asphalt roads corresponding to normal driving conditions and muddy roads corresponding to off-road driving conditions, thereby identifying the current driving condition of vehicle 1000. Radars can identify the current driving condition of vehicle 1000 by detecting the unevenness of the road surface.
[0099] The adjustment signal may include a first adjustment signal and a second adjustment signal. When the recognition component identifies that the vehicle 1000 is in a normal operating condition, the first adjustment signal may be generated and sent to the airbag control device 200. The airbag control device 200 may then receive the first adjustment signal and adjust the control strategy to the first strategy. When the recognition component identifies that the vehicle 1000 is in an off-road operating condition, the second adjustment signal may be generated and sent to the airbag control device 200. The airbag control device 200 may then receive the second adjustment signal and adjust the control strategy to the second strategy.
[0100] In this way, the vehicle 1000 can automatically adjust the control strategy of the airbag assembly 300 according to the environment, preventing the user from forgetting to adjust the control strategy and causing the collision ignition function and the rollover ignition function to be mistakenly triggered.
[0101] See also Figure 1 and Figure 2 In some embodiments, the airbag system 400 includes a collection component for collecting the adjustment signal and sending the adjustment signal to the airbag control device 200 .
[0102] Specifically, the airbag system 400 includes a collection component for collecting adjustment signals. The collection component includes one or more sensors. For example, the adjustment signal may include any one or more of the yaw angle of the vehicle 1000, the acceleration of the vehicle 1000, the steering angle of the vehicle 1000, the body inclination of the vehicle 1000, and the power supply voltage of the airbag control system 400. Correspondingly, the collection component may include any one or more of a yaw angle sensor, an acceleration sensor, a steering angle sensor, a tilt sensor, and a voltage sensor.
[0103] See also Figure 1 In some embodiments, the airbag control device 200 is configured to adjust the control strategy to the first strategy based on the adjustment signal when the adjustment signal is less than or equal to a preset adjustment threshold. The airbag control device 200 is further configured to adjust the control strategy to the second strategy based on the adjustment signal when the adjustment signal is greater than the preset adjustment threshold.
[0104] Specifically, when the adjustment signal includes the vehicle's yaw angle, a yaw angle threshold can be pre-set as a preset adjustment threshold. When the yaw angle is less than or equal to the yaw angle threshold, the airbag control device 200 can adjust the control strategy to the first strategy. When the yaw angle is greater than the yaw angle threshold, the airbag control device 200 can adjust the control strategy to the second strategy.
[0105] When the adjustment signal includes vehicle acceleration, an acceleration threshold can be pre-set as a preset adjustment threshold. When the acceleration is less than or equal to the acceleration threshold, the airbag control device 200 can adjust the control strategy to the first strategy. When the acceleration is greater than the acceleration threshold, the airbag control device 200 can adjust the control strategy to the second strategy.
[0106] When the adjustment signal includes the vehicle's steering angle, a steering angle threshold can be pre-set as a preset adjustment threshold. When the steering angle is less than or equal to the steering angle threshold, the airbag control device 200 can adjust the control strategy to the first strategy. When the steering angle is greater than the steering angle threshold, the airbag control device 200 can adjust the control strategy to the second strategy.
[0107] When the adjustment signal includes the vehicle's body tilt, a body tilt threshold can be pre-set as the preset adjustment threshold. When the body tilt is less than or equal to the body tilt threshold, the airbag control device 200 can adjust the control strategy to the first strategy. When the body tilt is greater than the body tilt threshold, the airbag control device 200 can adjust the control strategy to the second strategy. The case where the adjustment signal includes the supply voltage of the airbag system 400 will be described in detail later.
[0108] It is understandable that the control strategy may be determined based on only one signal, or may be determined comprehensively based on a combination of multiple signals.
[0109] The process of determining the control strategy as the first strategy or the second strategy according to the adjustment signal is described in detail below.
[0110] See also Figures 1 to 3The present application also provides an airbag control method. The airbag control method is applied to the airbag system 400 of any of the above embodiments, and the airbag control method includes:
[0111] 010: Acquire an adjustment signal for determining a control strategy of the airbag assembly 300;
[0112] 020: Determine the control strategy as the first strategy or the second strategy based on the adjustment signal, wherein the second ignition threshold of the airbag assembly 300 under the second strategy is higher than the first ignition threshold of the airbag assembly 300 under the first strategy.
[0113] In the airbag control method of the embodiment of the present application, the control strategy for airbag assembly 300 includes a first strategy and a second strategy. Under the second strategy, the second ignition threshold of airbag assembly 300 is higher than the first ignition threshold of airbag assembly 300 under the first strategy. Thus, under normal driving conditions, if vehicle 1000 experiences a collision or rollover, the collision ignition function and the rollover ignition function can be promptly triggered to deploy the airbags. In off-road conditions, the collision ignition function and the rollover ignition function are less likely to be accidentally triggered.
[0114] The following description will be made by taking the adjustment signal including the power supply voltage of the airbag system 400 as an example.
[0115] See also Figure 1 、 Figure 2 and Figure 4 In some embodiments, the vehicle 1000 includes a power supply 100 for supplying power to the airbag system 400. The adjustment signal includes a power supply voltage. Obtaining the adjustment signal (i.e., 010) for determining the control strategy of the airbag assembly 300 includes:
[0116] 011: Obtain the supply voltage of the power supply 100;
[0117] At this time, determining the control strategy as the first strategy or the second strategy (i.e., 020) based on the adjustment signal includes:
[0118] 021: Perform voltage verification on the power supply voltage and obtain the verification result;
[0119] 022: Determine the control strategy as the first strategy or the second strategy based on the verification result.
[0120] Specifically, the airbag control device 200 includes a power module 210, a signal acquisition module 220, and a control module 230. The control module 230 may be a microcontroller unit (MCU). The power module 210 is connected to the power supply 100, which is used to supply power to the power module 210.
[0121] The power supply voltage of the power supply 100 is obtained, and the control module 230 performs voltage verification on the power supply voltage to determine whether the airbag assembly 300 needs to be inhibited, and obtains a verification result. According to the verification result, the control strategy can be determined as the first strategy or the second strategy.
[0122] For example, if the verification result is not inhibited, the control module 230 may determine the control strategy as the first strategy. If the verification result is inhibited, the control module 230 may determine the control strategy as the second strategy. Under the second strategy, the vehicle 1000 is less likely to accidentally trigger the crash ignition function and the rollover ignition function.
[0123] See also Figure 1 、 Figure 5 and Figure 6 In some embodiments, obtaining the supply voltage (011) of the power supply 100 includes:
[0124] 0111: collecting a first voltage from the power supply 100 to obtain a first voltage;
[0125] 0112: collecting a second voltage from the power supply 100 to obtain a second voltage;
[0126] Perform voltage verification on the power supply voltage and obtain the verification result (i.e. 021), including:
[0127] 0211: Perform voltage verification on the first voltage and the second voltage to obtain a verification result.
[0128] Specifically, the signal acquisition module 220 and the control module 230 can each perform voltage acquisition on the power supply 100. That is, the acquisition component in the aforementioned embodiment can include the signal acquisition module 220 and the control module 230. The signal acquisition module 220 acquires a first voltage from the power supply 100, obtaining a first voltage; the control module 230 acquires a second voltage from the power supply 100, obtaining a second voltage. The signal acquisition module 220 can transmit the acquired first voltage to the control module 230. The control module 230 verifies the first and second voltages, and determines a verification result based on the first and second voltages.
[0129] It is understood that due to the different internal designs of signal acquisition module 220 and control module 230, the voltage acquisition accuracy varies, resulting in a discrepancy between the first voltage and the second voltage. Compared to verifying the voltage collected by a single module, the verification result determined by combining the first and second voltages using a redundant strategy is more accurate, thereby ensuring accurate airbag control.
[0130] Related technologies employ human-machine interface interaction to suppress the rollover function after verification and inspection. Alternatively, sensors detect the motion trajectory and dynamically adjust the airbag's restraint capability based on the trajectory. However, in certain scenarios, even if the vehicle's rollover mitigation function is suppressed, the vehicle's collision ignition function can still be triggered. Neither of these solutions can completely suppress all of the vehicle's airbags.
[0131] In this embodiment of the present application, signal acquisition module 220 and control module 230 respectively acquire the voltage of power supply 100. A redundancy strategy is then used to combine the first and second voltages to determine a verification result. Based on the verification result, control module 230 can inhibit airbag assembly 300. Airbag assembly 300 can control the deployment of all airbags. By inhibiting airbag assembly 300, all airbags in vehicle 1000 can be inhibited, resolving the issue of erroneous triggering of the collision ignition and rollover ignition functions in off-road scenarios.
[0132] See also Figure 1 、 Figure 6 and Figure 7 In some embodiments, the power supply 100 includes an activation power supply Ign1 and an auxiliary power supply Ign2. The first voltage includes a first activation voltage and a first auxiliary voltage. The second voltage includes a second activation voltage and a second auxiliary voltage. The first voltage acquisition of the power supply 100 to obtain the first voltage (i.e., 0111) includes:
[0133] 01111: collecting a first voltage of the activation power supply Ign1 and the auxiliary power supply Ign2 to obtain a first activation voltage and a first auxiliary voltage;
[0134] At this time, the second voltage of the power supply 100 is collected to obtain the second voltage (ie, 0112), including:
[0135] 01121: collecting a second voltage of the activation power supply Ign1 and the auxiliary power supply Ign2 to obtain a second activation voltage and a second auxiliary voltage;
[0136] At this time, the first voltage and the second voltage are verified to obtain a verification result (i.e., 0211), including:
[0137] 02111: Perform voltage verification on the first activation voltage, the first auxiliary voltage, the second activation voltage, and the second auxiliary voltage to obtain a verification result.
[0138] Specifically, the power supply 100 employs a redundant design and includes an active power supply Ign1 and an auxiliary power supply Ign2. A first switch 101 and a second switch 102 may be provided between the power supply 100 and the power module 210. The first switch 101 controls the path between the active power supply Ign1 and the power module 210, while the second switch 102 controls the path between the auxiliary power supply Ign2 and the power module 210.
[0139] The first voltage includes a first activation voltage and a first auxiliary voltage. The signal acquisition module 220 collects voltages of the activation power supply Ign1 and the auxiliary power supply Ign2 respectively to obtain the corresponding first activation voltage and first auxiliary voltage. The signal acquisition module 220 can send the collected first activation voltage and first auxiliary voltage to the control module 230 for verification in the control module 230.
[0140] The second voltage includes a second activation voltage and a second auxiliary voltage. The second activation voltage and the second auxiliary voltage can be obtained by respectively sampling the voltages of the activation power supply Ign1 and the auxiliary power supply Ign2 through the control module 230. The first activation voltage, the first auxiliary voltage, the second activation voltage, and the second auxiliary voltage can be verified by the control module 230 to obtain a verification result.
[0141] See also Figure 1 、 Figure 6 and Figure 8 In some embodiments, performing voltage verification on the first activation voltage, the first auxiliary voltage, the second activation voltage, and the second auxiliary voltage to obtain a verification result (i.e., 02111) includes:
[0142] 021111: Perform voltage verification on the first activation voltage and the second activation voltage to determine the voltage state of the activation power supply Ign1;
[0143] 021112: Perform voltage verification on the first auxiliary voltage and the second auxiliary voltage to determine the voltage state of the auxiliary power supply Ign2;
[0144] 021113: Determine the verification result according to the voltage status of the activation power supply Ign1 and the auxiliary power supply Ign2.
[0145] Specifically, after the control module 230 obtains the first activation voltage, the first auxiliary voltage, the second activation voltage and the second auxiliary voltage, it filters the first activation voltage, the first auxiliary voltage, the second activation voltage and the second auxiliary voltage respectively to remove noise and interference signals therein, thereby ensuring the accuracy of the verification results and thus ensuring the accuracy of the airbag control.
[0146] After filtering, the voltage state of the activation power supply Ign1 can be determined based on the first activation voltage and the second activation voltage. The voltage state of the auxiliary power supply Ign2 can also be determined based on the first auxiliary voltage and the second auxiliary voltage. The verification result can then be determined by combining the voltage states of the activation power supply Ign1 and the auxiliary power supply Ign2.
[0147] A process of determining the voltage state of the activation power source Ign1 according to the first activation voltage and the second activation voltage is described in detail below.
[0148] See also Figure 1 、 Figure 6 and Figure 9 In some embodiments, the voltage state includes an undervoltage state and a normal state. Performing voltage verification on the first activation voltage and the second activation voltage to determine the voltage state of the activation power supply Ign1 (i.e., 021111) includes:
[0149] 0211111: when the first activation voltage is less than the first preset threshold and the second activation voltage is less than the second preset threshold, it is determined that the activation power source Ign1 is in an undervoltage state;
[0150] 0211112: When the first activation voltage is greater than or equal to the first preset threshold, and / or the second activation voltage is greater than or equal to the second preset threshold, it is determined that the activation power source Ign1 is in a normal state, and the process returns to the step of obtaining the power supply voltage of the power supply 100.
[0151] Specifically, the first activation voltage is compared with a first preset threshold. The first preset threshold represents the minimum value allowed for the first activation voltage and can be set based on the internal design of the signal acquisition module 220 and the voltage output by the activation power supply Ign1. If the first activation voltage is less than the first preset threshold, it indicates that the activation power supply Ign1 may be in an undervoltage state. If the first activation voltage is greater than or equal to the first preset threshold, it indicates that the activation power supply Ign1 may be in a normal state.
[0152] The second activation voltage is compared with a second preset threshold. The second preset threshold represents the minimum value allowed for the second activation voltage and can be set based on the internal design of control module 230 and the voltage output by activation power supply Ign1. If the second activation voltage is less than the second preset threshold, activation power supply Ign1 may be in an undervoltage state. If the second activation voltage is greater than or equal to the second preset threshold, activation power supply Ign1 may be in a normal state.
[0153] A logical AND operation is performed on the comparison results of the first activation voltage and the second activation voltage to comprehensively determine the voltage status of activation power supply Ign1. If the filtered first activation voltage is less than a first preset threshold, and the second activation voltage is less than a second preset threshold, activation power supply Ign1 is determined to be in an undervoltage state. In other words, activation power supply Ign1 is only determined to be in an undervoltage state when both the first activation voltage and the second activation voltage are less than their corresponding thresholds. This avoids false positives and ensures the accuracy of subsequent verification results.
[0154] When the first activation voltage is greater than or equal to the first preset threshold and the second activation voltage is less than the second preset threshold; or when the first activation voltage is less than the first preset threshold and the second activation voltage is greater than or equal to the second preset threshold; or when the first activation voltage is greater than or equal to the first preset threshold and the second activation voltage is greater than or equal to the second preset threshold, it is determined that the activation power supply Ign1 is in a normal state.
[0155] When it is determined that the activation power source Ign1 is in a normal state, the process returns to the step of acquiring the supply voltage of the power supply 100 , continuously and cyclically acquires the voltage of the activation power source Ign1 , and determines the voltage state.
[0156] The process of determining the voltage state of the auxiliary power supply Ign2 according to the first auxiliary voltage and the second auxiliary voltage is described in detail below.
[0157] See also Figure 1 、 Figure 6 and Figure 10 In some embodiments, the voltage state includes an undervoltage state and a normal state. Performing voltage verification on the first auxiliary voltage and the second auxiliary voltage to determine the voltage state of the auxiliary power supply Ign2 (i.e., 021112) includes:
[0158] 0211121: when the first auxiliary voltage is less than the third preset threshold and the second auxiliary voltage is less than the fourth preset threshold, it is determined that the auxiliary power supply Ign2 is in an undervoltage state;
[0159] 0211122: When the first auxiliary voltage is greater than or equal to the third preset threshold, and / or the second auxiliary voltage is greater than or equal to the fourth preset threshold, it is determined that the auxiliary power supply Ign2 is in a normal state, and the step of obtaining the power supply voltage of the power supply 100 is returned.
[0160] Specifically, the first auxiliary voltage is compared with a third preset threshold. The third preset threshold represents the minimum allowable value of the first auxiliary voltage and can be set based on the internal design of the signal acquisition module 220 and the voltage output by the auxiliary power supply Ign2. If the first auxiliary voltage is less than the third preset threshold, it indicates that the auxiliary power supply Ign2 may be in an undervoltage state. If the first auxiliary voltage is greater than or equal to the third preset threshold, it indicates that the auxiliary power supply Ign2 may be in a normal state.
[0161] The second auxiliary voltage is compared with a fourth preset threshold. The fourth preset threshold represents the minimum allowable value of the second auxiliary voltage and can be set based on the internal design of the control module 230 and the voltage output by the auxiliary power supply Ign2. If the second auxiliary voltage is less than the fourth preset threshold, the auxiliary power supply Ign2 may be in an undervoltage state. If the second auxiliary voltage is greater than or equal to the fourth preset threshold, the auxiliary power supply Ign2 may be in a normal state.
[0162] A logical AND operation is performed on the comparison results of the first auxiliary voltage and the second auxiliary voltage to comprehensively determine the voltage status of the auxiliary power supply Ign2. When the first auxiliary voltage is less than the third preset threshold and the second auxiliary voltage is less than the fourth preset threshold, the auxiliary power supply Ign2 is determined to be in an undervoltage state. In other words, the auxiliary power supply Ign2 is only determined to be in an undervoltage state when both the first and second auxiliary voltages are less than their corresponding thresholds. This avoids misjudgments and ensures the accuracy of subsequent verification results.
[0163] When the first auxiliary voltage is greater than or equal to the third preset threshold and the second auxiliary voltage is less than the fourth preset threshold; or, when the first auxiliary voltage is less than the third preset threshold and the second auxiliary voltage is greater than or equal to the fourth preset threshold; or, when the first auxiliary voltage is greater than or equal to the third preset threshold and the second auxiliary voltage is greater than or equal to the fourth preset threshold, the auxiliary power supply Ign2 is determined to be in a normal state.
[0164] It should be noted that the first preset threshold and the third preset threshold may be the same or different. The second preset threshold and the fourth preset threshold may be the same or different.
[0165] When it is determined that the auxiliary power supply Ign2 is in a normal state, the process returns to the step of acquiring the power supply voltage of the power supply 100 , continuously and cyclically acquires the voltage of the auxiliary power supply Ign2 , and determines the voltage state.
[0166] After determining the voltage states of the active power supply Ign1 and the auxiliary power supply Ign2, a verification result can be determined based on the voltage states of the active power supply Ign1 and the auxiliary power supply Ign2. The process of determining the verification result is described in detail below.
[0167] See also Figure 1 、 Figure 6 、 Figure 11 and Figure 12 In some embodiments, determining a verification result (i.e., 021113) based on the voltage states of the active power supply Ign1 and the auxiliary power supply Ign2 includes:
[0168] 0211131: Get the voltage status of the activation power supply Ign1;
[0169] 0211132: When the activation power supply Ign1 is in an undervoltage state, the check result is determined to be inhibited;
[0170] 0211133: when the active power supply Ign1 is in a normal state, obtaining the voltage state of the auxiliary power supply Ign2 to determine a verification result according to the voltage state of the auxiliary power supply;
[0171] At this time, the control strategy is determined as the first strategy or the second strategy (i.e., 022) according to the verification result, including:
[0172] 0221: When the verification result is suppression, the control strategy is determined to be the second strategy.
[0173] See also Figure 1 、 Figure 6 、 Figure 12 and Figure 13 , determine the verification result (i.e. 0211133) according to the voltage status of the auxiliary power supply, including:
[0174] 02111331: When the auxiliary power supply Ign2 is in an undervoltage state, the verification result is determined to be a fault;
[0175] 02111332: When the auxiliary power supply Ign2 is in a normal state, return to the step of obtaining the voltage state of the activation power supply Ign1.
[0176] Specifically, the voltage status of the activation power supply Ign1 is obtained. If the activation power supply Ign1 is in an undervoltage state, the verification result is determined to be suppression, and the airbag assembly 300 needs to be suppressed by the control module 230. If the activation power supply Ign1 is in a normal state, the voltage status of the auxiliary power supply Ign2 is further obtained.
[0177] If auxiliary power supply Ign2 is undervoltage, the verification result indicates an auxiliary power supply Ign2 fault, and an auxiliary power supply Ign2 undervoltage fault code is recorded. Based on the auxiliary power supply Ign2 undervoltage fault code, control module 230 can issue a fault alarm. If auxiliary power supply Ign2 is normal, it indicates that there is no need to inhibit airbag assembly 300. The process returns to the step of obtaining the voltage status of activation power supply Ign1 to obtain the latest voltage status of activation power supply Ign1 and redetermine the verification result.
[0178] In actual applications, the user can manually control the first switch 101 and the second switch 102. Manual operation of the first and second switches 101, 102 can serve as the signal source for the adjustment signal in the aforementioned embodiment. For example, to deactivate the airbag, the user can control the first switch 101 to open and the second switch 102 to close. At this point, the path between the activation power supply Ign1 and the power module 210 is disconnected, while the path between the auxiliary power supply Ign2 and the power module 210 is connected. If the collected first activation voltage is less than the first preset threshold and the second activation voltage is less than the second preset threshold, it can be determined that the activation power supply Ign1 is in an undervoltage state. Consequently, the verification result indicates deactivation, and the airbag assembly 300 can be deactivated by the control module 230, thereby achieving airbag deactivation.
[0179] It should be noted that the user may make an operational error when controlling the first switch 101 and the second switch 102. For example, when the user wants to suppress the airbag or in other situations, the user controls the first switch 101 to be closed and the second switch 102 to be opened.
[0180] At this point, the path between the active power supply Ign1 and the power module 210 is connected, while the path between the auxiliary power supply Ign2 and the power module 210 is disconnected. If the first activation voltage detected is greater than or equal to the first preset threshold, and the second activation voltage is greater than or equal to the second preset threshold, the active power supply Ign1 is determined to be in a normal state. If the first auxiliary voltage detected is less than the third preset threshold, and the second auxiliary voltage is less than the fourth preset threshold, the auxiliary power supply Ign2 is determined to be in an undervoltage state.
[0181] In this case, the check result is that the auxiliary power supply Ign2 fails, and the control module 230 can promptly issue an alarm based on the check result to inform the user of an operation error. In this way, safety hazards caused by user misoperation can be avoided.
[0182] See also Figure 1 In some embodiments, the airbag control device 200 further includes a driver module 240. The control module 230, the driver module 240, and the airbag assembly 300 are sequentially connected. If the verification result indicates suppression, the control module 230 sends a suppression signal to the driver module 240, causing the driver module to adjust the control strategy of the airbag assembly 300 to the second strategy.
[0183] Specifically, the airbag control device 200 further includes a driver module 240, and the control module 230 is connected to the driver module 240. When the verification result is inhibition, the control module 230 sends an inhibition signal to the driver module 240. The driver module 240 is connected to the airbag assembly 300 and is configured to control the airbag assembly 300. The driver module 240 can adjust the control strategy of the airbag assembly 300 to the second strategy based on the inhibition signal.
[0184] The airbag control device 200 also includes a sensor, which can be a collision sensor. The sensor is used to detect impact force and obtain a detection result. The sensor can also send the detection result to the control module 230, which can determine whether to deploy the airbag based on the detection result.
[0185] When the airbag needs to be deployed, the control module 230 sends an enable signal to the driver module 240. After receiving the enable signal, the driver module 240 can send a corresponding control signal to the airbag assembly 300 based on the enable signal, causing the airbag assembly 300 to deploy the airbag. In one example, the control signal can be a 1.2A current signal lasting 2ms.

[0197] For example, when the computer program 610 is executed by the processor 620, the following airbag control method is implemented:
[0198] 010: Acquire an adjustment signal for determining a control strategy of the airbag assembly 300;
[0199] 020: Determine the control strategy as the first strategy or the second strategy based on the adjustment signal, wherein the second ignition threshold of the airbag assembly under the second strategy is higher than the first ignition threshold of the airbag assembly under the first strategy.
[0200] For another example, when the computer program 610 is executed by the processor 620, the following airbag control method is implemented:
[0201] 011: Obtain the supply voltage of the power supply 100;
[0202] At this time, determining the control strategy as the first strategy or the second strategy (i.e., 020) based on the adjustment signal includes:

[0205] It should be noted that the explanations of the airbag system 400 and the airbag control method in the aforementioned embodiments are also applicable to the computer-readable storage medium 600 in the embodiments of the present application and will not be further explained here.
[0206] See also Figure 1 The embodiment of the present application further provides a vehicle 1000, which includes an airbag system 400. The airbag system 400 is used to implement the airbag control method of any of the above embodiments.
[0207] Specifically, the airbag system 400 may be disposed at the front or middle portion of the vehicle 1000 so as to ignite and deploy the airbags to protect the driver and passengers in the event of a collision or rollover.
[0208] In summary, in the airbag system 400, airbag control method, electronic device 500, computer-readable storage medium 600, and vehicle 1000 of the embodiments of the present application, the control strategy for the airbag assembly 300 includes a first strategy and a second strategy. Under the second strategy, the second ignition threshold of the airbag assembly 300 is higher than the first ignition threshold of the airbag assembly 300 under the first strategy. This reduces the likelihood of inadvertent triggering of the crash ignition function and the rollover ignition function in off-road conditions.
