Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] According to one embodiment of the present invention, an embodiment of a test method for airbag deployment control is provided.

Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0027] This method embodiment can be executed in a computer terminal or similar computing device with memory and processor. Taking running on a computer terminal as an example, such as... Figure 1As shown, a computer terminal may include one or more processors 102 (processors may include, but are not limited to, central processing units (CPUs), graphics processing units (GPUs), digital signal processing (DSP) chips, microprocessors (MCUs), programmable logic devices (FPGAs), neural network processors (NPUs), tensor processors (TPUs), artificial intelligence (AI) type processors, etc.) and a memory 104 for storing data.

Those skilled in the art will understand that... Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the computer terminal described above. For example, the computer terminal may include more or fewer components than those described above, or have a different configuration than those described above.

[0028] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the airbag deployment control test method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby realizing the aforementioned airbag deployment control test method.

[0031] This embodiment provides a test method for airbag deployment control running on the aforementioned computer terminal. Figure 2 This is a flowchart of a test method for airbag deployment control according to one embodiment of the present invention, as shown below. Figure 2 As shown, the process includes the following steps:

[0032] Step S21: Obtain test items. Test items include at least test fault items and vehicle collision type. Test fault items include at least target fault sensor, sensor fault type, and fault duration.

[0033] Step S22: Based on the test failure items, input the fault simulation signal corresponding to the test failure items into the airbag control system;

[0034] Step S23: Based on the vehicle collision type, input a collision simulation signal corresponding to the vehicle collision type to the airbag control system;

[0035] Step S24: Detect the output control signal of the airbag control system within the preset test duration, where the preset test duration is longer than the fault duration setting;

[0036] Step S25: Based on the output control signal, generate the test results of the airbag control system.

[0037] Through the above steps, test items are obtained, including at least test fault items and vehicle collision types. Test fault items include at least the target fault sensor, sensor fault type, and fault duration. Based on the test fault items, a fault simulation signal corresponding to the test fault item is input to the airbag control system. Based on the vehicle collision type, a collision simulation signal corresponding to the vehicle collision type is input to the airbag control system. The output control signal of the airbag control system is detected within a preset test duration, where the preset test duration is longer than the fault duration setting. Based on the output control signal, the test results of the airbag control system are generated. The testing method in this embodiment simulates a malfunction in the airbag deployment control system and inputs a simulated vehicle collision signal to the airbag control system. This allows for testing the deployment control function when the airbag control system malfunctions. By detecting the output control signal, it is possible to determine whether the airbag deployment function of the control system is normal. This makes the pre-shipment testing and analysis of the airbag control system more accurate, enabling timely detection of system problems and repair of the control system, reducing the risk of loss of airbag deployment capability. At the same time, compared with whole vehicle testing, the method in this embodiment has a shorter testing cycle and lower testing cost, solving the technical problems of limitations, high testing costs, and long testing cycles in related airbag deployment control system testing methods.

[0038] In the embodiments of this application, the airbag deployment control system includes sensors, a controller, and an airbag module. The sensors include a collision acceleration sensor and a collision pressure sensor. The controller receives collision signals from the internal components and sensors and analyzes the collision signals to determine whether a collision has occurred and whether the airbag needs to be deployed.

[0039] Optionally, in step S21, the sensor fault types include electrical faults, bus faults, and power supply faults. Electrical faults include open circuits, short circuits to ground, and short circuits to the power supply. Bus faults include vehicle signal communication faults, and power supply faults include power mode switching.

[0040] In this embodiment, by setting multiple sensor fault types for testing, the final test results of the airbag deployment control system's deployment function can be more complete, covering more real-world working conditions, and effectively avoiding the risk of airbag deployment control system malfunction.

[0041] Optionally, in step S21, the target fault sensor is at least one of the vehicle's collision acceleration sensor and collision pressure sensor. The collision acceleration sensor includes a left front collision acceleration sensor, a left side collision acceleration sensor, a right front collision acceleration sensor, and a right side collision acceleration sensor. The collision pressure sensor includes a left side collision pressure sensor and a right side collision pressure sensor. Generally, the airbag deployment control system determines whether to deploy the airbag by collecting vehicle collision signals. By using the collision acceleration sensor and the collision pressure sensor as target fault sensors, it is possible to directly determine whether the airbag deployment control system deploys normally when the relevant sensors in a vehicle collision malfunction, making the final system test results more accurate.

[0042] In one exemplary embodiment of this application, a single-point testing method is adopted, that is, only one target fault sensor is set for each test, while the other sensors are kept normal. For example, the target fault sensor is set as the left front collision acceleration sensor, while the left side collision acceleration sensor and the left side collision pressure sensor are kept normal.

[0043] Those skilled in the art should understand that, depending on actual needs, the number of target fault sensors can be two, three, or other types to comprehensively measure the function of the airbag deployment control system.

[0044] Optionally, in step S23, the collision simulation signal includes at least the collision sensor simulation signal, and the collision sensor includes at least the vehicle's collision acceleration sensor and collision pressure sensor. The collision acceleration sensor includes a left front collision acceleration sensor, a left side collision acceleration sensor, a right front collision acceleration sensor, and a right side collision acceleration sensor, and the collision pressure sensor includes a left side collision pressure sensor and a right side collision pressure sensor.

[0045] In this embodiment, the vehicle collision condition is simulated by simulating the signals generated by the vehicle's collision acceleration sensor and collision pressure sensor. Compared with real vehicle test simulation, this reduces test costs and shortens the test cycle. At the same time, the collision acceleration sensor and collision pressure sensor are signal acquisition devices for the vehicle to judge the collision condition. The simulated collision sensor signals can be directly used as input signals for the airbag deployment control system to perform deployment function control judgment.

[0046] In one exemplary embodiment of this application, the target fault sensor is set as the left front collision acceleration sensor, and collision simulation signals of the left side collision acceleration sensor and the left side collision pressure sensor are generated to simulate the collision condition of the left side of the vehicle. Then, the airbag deployment control system can be judged to determine whether the airbag deployment control system can control the deployment normally based on whether the left side airbag in the vehicle deploys.

[0047] Those skilled in the art should understand that the deployment control of the airbags on the left and right sides of a vehicle can be performed simultaneously. That is, one sensor on the left and one on the right can be malfunctioned at the same time, and a vehicle collision can be simulated on both sides simultaneously to observe whether the airbags on both sides can deploy normally. Alternatively, the deployment control test of the airbags on one side can be performed separately.

[0048] Optionally, in step S21, the vehicle collision types include at least driver-side collision and passenger-side collision. Driver-side and passenger-side collision tests can cover the main vehicle collision conditions in real-world applications, making the test results of the airbag deployment control system more accurate and reducing the safety risks to occupants.

[0049] Those skilled in the art should understand that, depending on the location and number of airbags in an actual vehicle, tests for even more types of vehicle collisions can be set up.

[0050] Optionally, in step S24, the preset test duration is 15 seconds. Setting an appropriate preset test duration can obtain accurate test results for the airbag deployment control system. The preset test duration can be adjusted according to actual needs.

[0051] Optionally, in step S21, the fault duration is 10 seconds. Setting an appropriate fault duration can obtain accurate test results for the airbag deployment control system. The fault duration can be adjusted according to actual needs.

[0052] It should be noted that the preset test duration should be longer than the fault duration. That is, the output signal of the airbag deployment control system is tested during the fault and after the fault is recovered. This is to make it easier to determine whether the airbag deployment control system can deploy normally based on the output signal.

[0053] Optionally, before obtaining the test item, the method may also include:

[0054] Step S201: Power on the airbag control system;

[0055] Step S202: Check whether the airbag control system is operating normally;

[0056] Step S203: After confirming that the airbag control system is operating normally, obtain the test items;

[0057] Step S204: If it is determined that the airbag control system is malfunctioning, troubleshoot the airbag control system.

[0058] By using steps S201-S204, before obtaining the test items, it is determined whether the airbag control system is operating normally after power-on, and if the airbag control system is malfunctioning, the problem can be investigated in a timely manner to avoid inaccurate test results caused by abnormalities in the airbag control system itself.

[0059] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.

[0060] This embodiment also provides a testing device for airbag deployment control, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0061] Figure 3 This is a structural block diagram of a test device for airbag deployment control according to one embodiment of the present invention, as shown below. Figure 3 As shown, the device includes: an acquisition module 30, used to acquire test items, which at least include test fault items and vehicle collision types, and the test fault items at least include fault sensors, sensor fault types, and fault duration; a fault simulation module 32, used to input fault simulation signals corresponding to the test fault items to the airbag control system; a collision simulation module 34, used to input collision simulation signals corresponding to the vehicle collision type to the airbag control system; a detection module 36, used to detect the output control signals of the airbag control system within a preset test duration, where the preset test duration is longer than the fault duration setting; and a generation module 38, used to generate test results for the airbag control system based on the output control signals.

[0062] Using the aforementioned device, test items are acquired, including at least test fault items and vehicle collision types. Test fault items include at least the target fault sensor, sensor fault type, and fault duration. Based on the test fault items, a fault simulation signal corresponding to the test fault item is input to the airbag control system. Based on the vehicle collision type, a collision simulation signal corresponding to the vehicle collision type is input to the airbag control system. The output control signal of the airbag control system is detected within a preset test duration, where the preset test duration is longer than the fault duration setting. Based on the output control signal, the test results of the airbag control system are generated. The testing method in this embodiment simulates a malfunction in the airbag deployment control system and inputs a simulated vehicle collision signal to the airbag control system. This allows for testing the deployment control function when the airbag control system malfunctions. By detecting the output control signal, it is possible to determine whether the airbag deployment function of the control system is normal. This makes the pre-shipment testing and analysis of the airbag control system more accurate, enabling timely detection of system problems and repair of the control system, reducing the risk of loss of airbag deployment capability. At the same time, compared with whole vehicle testing, the method in this embodiment has a shorter testing cycle and lower testing cost, solving the technical problems of limitations, high testing costs, and long testing cycles in related airbag deployment control system testing methods.

[0063] It should be noted that the above modules can be implemented by software or hardware. For the latter, they can be implemented in the following ways, but are not limited to: all the above modules are located in the same processor; or, the above modules are located in different processors in any combination.

[0064] like Figure 5 and Figure 6 As shown, this application also provides a functional safety test system for airbag deployment control. The functional safety test system includes a host computer and a HIL cabinet. The host computer runs an automated test program to control the real-time system in the HIL cabinet. Each I / O interface and CAN bus interface in the HIL cabinet is responsible for connecting to the airbag control system, including the ACU, collision acceleration sensor, and collision pressure sensor, to realize information exchange between the controller and the equipment. The sensor and actuator fault injection board in the HIL cabinet is used for injecting and recovering faults.

[0065] Specifically, the host computer includes fault injection software, an airbag control unit model, and a vehicle model. The vehicle model and the airbag control unit model are used for simulation analysis of the vehicle and the airbag control unit, respectively. The HIL cabinet includes a real-time processor, a CAN bus board, and a multi-functional I / O board. The host computer and the HIL cabinet communicate in real time via Ethernet. The HIL cabinet communicates with the airbag controller via a CAN bus.

[0066] like Figure 4 As shown, the steps for testing the full airbag deployment control using a functional safety testing system for airbag deployment control are as follows:

[0067] Step 1: Compile a test case library based on functional safety requirements and safety objectives;

[0068] Step Two: Based on the test case library established in Step One, build a fault injection test environment. Electrical faults include open circuit, short circuit to ground, and short circuit to power supply. Figure 4 The diagram shows an electrical fault injection test. Bus-related faults include communication failures of signals such as vehicle speed, while power supply faults mainly include power mode switching.

[0069] Step 3: Power on the host computer and confirm that the airbag deployment control system is functioning correctly;

[0070] Step 4: Run the testing equipment to start collecting key data signals and monitor the airbag deployment control system signals;

[0071] Step 5: According to the fault types of the collision acceleration sensor and collision pressure sensor written in the test case library, use the host computer fault injection software to inject open circuit, short circuit to ground, and short circuit to power supply faults of the collision acceleration sensor and collision pressure sensor.

[0072] Step Six: According to Step Five, maintain the fault duration for 10 seconds, use the collision pressure sensor and collision acceleration sensor to simulate vehicle collision types, such as driver's side collision, passenger side collision, etc., and continue to observe the signal until 5 seconds after the fault is recovered;

[0073] Step 7: Control the vehicle to stop by braking, and shift the gear to P;

[0074] Step 8: End the acquisition of key data signals, store the data, and power off the host computer;

[0075] Step 9: Analyze the bus data to check whether the airbags deployed during the simulated collision during the fault period, and compare the actual test results with the functional safety targets to determine whether the airbag deployment function has been lost.

[0076] The functional safety testing system for airbag deployment control in this embodiment is a hardware-in-the-loop testing system for the airbag control unit. Combined with corresponding in-the-loop testing methods, it verifies test conditions where airbag deployment capability is lost. This can effectively reduce or prevent the risk of airbag deployment capability loss, significantly shorten the project development cycle, and reduce experimental costs. At the same time, by establishing a test case database based on publicly available typical traffic accidents and after-sales feedback cases, it can verify various real-world operating conditions, effectively reducing the risk of false airbag triggering, greatly improving the correct triggering probability of airbags, and protecting the lives and property of drivers and passengers.
