Description

Technical Field

[0001] This disclosure relates to the field of vehicle processing technology, and in particular to a method, apparatus and electronic device for simulating vehicle collision triggering parameters. Background Technology

[0002] When a vehicle is involved in a collision, the digital signal generated by the impact force will notify the user when it reaches the trigger value of the gravity sensor. However, the trigger value of the gravity sensor is mainly defined directly based on experience. This method of determining the trigger value is inaccurate, resulting in low sensitivity of the gravity sensor. This can lead to situations where the vehicle is hit but the gravity sensor does not trigger, affecting the user experience.

[0003] Therefore, improving the accuracy of the trigger values ​​of the vehicle's gravity sensor has become an urgent technical problem to be solved. Summary of the Invention

[0004] In view of this, the purpose of this disclosure is to provide a method, apparatus and electronic device for simulating vehicle collision triggering parameters, so as to solve the problem of inaccurate vehicle gravity sensor triggering values ​​in the prior art.

[0005] To achieve the above objectives, a first aspect of this disclosure provides a method for simulating vehicle collision triggering parameters, the method comprising:

[0006] Based on predetermined settings parameters, a collision simulation object is controlled to simulate a collision scenario with a target vehicle, and the first collision trigger value of the target vehicle when the gravity sensor is triggered in the collision scenario is determined.

[0007] The target trigger value corresponding to the gravity sensor of the target vehicle is determined based on the first collision trigger value.

[0008] Based on the same inventive concept, a second aspect of this disclosure proposes a device for simulating vehicle collision triggering parameters, comprising:

[0009] The collision simulation module is configured to control a collision simulation object to simulate a collision scenario with a target vehicle based on predetermined setting parameters, and to determine the first collision trigger value of the target vehicle when the gravity sensor is triggered in the collision scenario.

[0010] The trigger value determination module is configured to determine the target trigger value corresponding to the gravity sensor of the target vehicle based on the first collision trigger value.

[0011] Based on the same inventive concept, a third aspect of this disclosure proposes an electronic device including a memory, a processor, and a computer program stored in the memory and executable by the processor, wherein the processor implements the method described above when executing the computer program.

[0012] As described above, this disclosure provides a method, apparatus, and electronic device for simulating vehicle collision trigger parameters. By controlling a collision simulation object to simulate a collision scenario with a target vehicle, the first collision trigger value of the target vehicle's gravity sensor under the collision scenario can be accurately determined. This makes the first collision trigger value more consistent with the trigger value of the gravity sensor under the collision scenario, and it eliminates the need for a real-vehicle collision, thus avoiding damage to the target vehicle. Based on the first collision trigger value, the target trigger value corresponding to the target vehicle's gravity sensor is determined, making the determined target trigger value more accurate. In this way, after calibrating the target vehicle's gravity sensor with the target trigger value, it can be guaranteed that the target vehicle's gravity sensor will be triggered under the collision scenario, thereby improving the sensitivity of the target vehicle's gravity sensor and ensuring a good user experience.

[0022] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this disclosure should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] Based on the description of the background technology, such as Figure 1 As shown, Figure 1 This is a flowchart of the vehicle sentry mode according to an embodiment of this disclosure. Currently, the principle of implementing the vehicle sentry mode function using a G-sensor (i.e., a gravity sensor) is as follows: When the vehicle is subjected to an external collision, the impact force causes the vehicle body to vibrate. The external environmental impact force is transmitted through the vehicle body structure module, shock absorption module, rigid connection module, etc., to the G-sensor sensor located in the vehicle's ECU (controller). The G-sensor sensor converts the received impact force into a voltage signal, and then converts the voltage signal into a digital signal (such as an acceleration value). Software sets a corresponding threshold (such as an acceleration threshold) for the G-sensor sensor as a trigger value. When the instantaneous acceleration received by the G-sensor sensor exceeds the acceleration threshold, an alarm signal is issued to notify the user. Therefore, the trigger value becomes a crucial parameter in the entire function.

[0025] G-sensors can identify acceleration values ​​in six directions: ±X, ±Y, and ±Z. Currently, the trigger values ​​for G-sensors on the market are mainly defined directly based on experience or by detecting common vibrations such as hood closing or door closing to determine the final defined trigger value. Furthermore, the trigger values ​​are the same in all six directions without differentiation between them. Due to the complex transmission path of collision force, the sensitivity of G-sensors in sentry mode is relatively low. Often, even after a collision that has resulted in a dent, the G-sensor may not trigger, leading to numerous user complaints and impacting the user experience.

[0026] Overall, there is currently no standardized or normalized scheme for determining the trigger value of G-sensor sensors, and the trigger value of G-sensor sensors is not calibrated in conjunction with collision scenarios in real life. Therefore, this embodiment proposes a calibration method for the trigger value of G-sensor sensors to solve the problem of low sensitivity of G-sensor sensors in sentinel mode in related technologies.

[0027] As mentioned above, improving the accuracy of the trigger values ​​of a vehicle's gravity sensor has become an important research question.

[0028] Based on the above description, such as Figure 2 As shown, the vehicle collision triggering parameter simulation method proposed in this embodiment is applied to a vehicle collision triggering parameter simulation device, and the method includes:

[0029] Step 101: Based on predetermined settings, control the collision simulation object to simulate a collision scenario with the target vehicle, and determine the first collision trigger value of the target vehicle when the gravity sensor is triggered in the collision scenario.

[0030] In practice, a collision simulation object is controlled to simulate collision scenarios on multiple predetermined collision areas on the target vehicle according to predetermined parameters, and the first collision trigger value of the target vehicle when the gravity sensor is triggered in the collision scenario is determined. For example, the collision simulation object is controlled to perform free fall collisions on multiple predetermined collision areas on the target vehicle according to predetermined parameters, and the first collision trigger value of the target vehicle when the gravity sensor is triggered in the collision scenario is determined.

[0031] The first collision trigger value is the trigger value when the gravity sensor of the target vehicle is triggered under the collision scenario simulation of the target vehicle.

[0032] The parameters are those related to the collision force generated by the collision simulation object. The collision parameters include at least one of the following: the collision simulation object's mass, the collision simulation object's height, and the collision simulation object's angle.

[0033] The collision simulation objects include collision pendulums or collision spheres. When the collision simulation object is a collision pendulum, the parameters to be set include: the mass of the collision pendulum, the length of the pendulum rod, and the swing angle.

[0034] Step 102: Determine the target trigger value corresponding to the gravity sensor of the target vehicle based on the first collision trigger value.

[0035] In specific implementation, the methods for determining the target trigger value corresponding to the gravity sensor of the target vehicle based on the first collision trigger value include: directly using the first collision trigger value as the target trigger value; or, modifying the first collision trigger value and using the modified first collision trigger value as the target trigger value.

[0036] Specifically, the methods for correcting the first collision trigger value to obtain the target trigger value include: multiplying the first collision trigger value with a preset correction coefficient to obtain the target trigger value; or summing the first collision trigger value with a preset gradient coefficient to obtain the target trigger value; or correcting the first collision trigger value based on the natural trigger value corresponding to the natural environment to obtain the target trigger value.

[0037] Through the above embodiments, by controlling a collision simulation object to simulate a collision scenario with the target vehicle, the first collision trigger value of the target vehicle's gravity sensor under the collision scenario can be accurately determined. This makes the first collision trigger value more consistent with the trigger value of the gravity sensor under the collision scenario, and it eliminates the need for a real-vehicle collision, thus avoiding damage to the target vehicle. Based on the first collision trigger value, the target trigger value corresponding to the target vehicle's gravity sensor is determined, making the determined target trigger value more accurate. In this way, after calibrating the target vehicle's gravity sensor with the target trigger value, it can be guaranteed that the target vehicle's gravity sensor will be triggered under the collision scenario, thereby improving the sensitivity of the target vehicle's gravity sensor and ensuring a good user experience.

[0038] In some embodiments, prior to step 101, the method further includes:

[0039] Step 1011: Conduct a real-vehicle collision on the vehicle and determine the second collision trigger value when the gravity sensor of the vehicle is triggered under the real-vehicle collision.

[0040] In practice, the collision vehicle is the vehicle used to determine the parameters of the collision simulation object during a real-vehicle collision. The second collision trigger value is the trigger value when the gravity sensor of the collision vehicle is triggered during a real-vehicle collision.

[0041] Multiple real-vehicle collision scenarios are identified for actual vehicle collisions. Multiple simulated real-vehicle trigger values ​​are obtained when the gravity sensor is triggered in multiple real-vehicle collision scenarios. The maximum value among the multiple simulated real-vehicle trigger values ​​is determined as the second collision trigger value.

[0042] Specifically, multiple collision areas, multiple collision methods, multiple collision objects, multiple collision velocities, and multiple collision angles are determined, and these multiple collision areas, multiple collision methods, multiple collision objects, multiple collision velocities, and multiple collision angles are combined to determine various real-vehicle collision scenarios.

[0043] Step 1012: Based on the second collision trigger value, determine the setting parameters corresponding to the collision simulation of the collision simulation object.

[0044] In practice, the collision simulation object is controlled to simulate a collision scenario with the vehicle, and the object trigger value triggered by the vehicle in the simulated collision scenario is obtained. When the difference between the object trigger value and the second collision trigger value is less than or equal to a preset trigger value threshold, the parameter information corresponding to the collision simulation object in simulating the collision scenario is used as the setting parameter.

[0045] For example, when the collision simulation object is a collision pendulum, collision pendulums with different masses and pendulum lengths are controlled to swing at different angles to simulate various collision scenarios with the vehicle, and multiple object trigger values ​​are obtained under various collision scenarios. From the multiple object trigger values, the target object trigger value with the smallest difference from the second collision trigger value is determined, and it is determined that the difference between the target object trigger value and the second collision trigger value is less than or equal to a preset trigger value threshold. The target collision scenario corresponding to the target object trigger value is determined, and the target mass, target pendulum length, and target swing angle of the collision pendulum under the target collision scenario are used as setting parameters.

[0046] The above scheme involves conducting real-vehicle collisions to determine the second collision trigger value when the gravity sensor is activated under real-vehicle collision conditions. When the object trigger value when the gravity sensor is activated under a collision scenario simulation using a collision simulator is close to the second collision trigger value, the parameter information corresponding to the collision scenario simulation using the collision simulator is used as the setting parameter. In this way, the determined setting parameter is more accurate through both real-vehicle collisions and collision scenario simulations using a collision simulator, thus making the first collision trigger value determined based on the setting parameter through collision scenario simulation of the target vehicle more accurate.

[0047] In some embodiments, step 1011 includes:

[0048] Step 1011A: Determine multiple real-vehicle collision scenarios for conducting a real-vehicle collision on the vehicle being collided with.

[0049] In practice, multiple collision areas, multiple collision methods, multiple collision objects, multiple collision speeds, and multiple collision angles are determined. These multiple collision areas, multiple collision methods, multiple collision objects, multiple collision speeds, and multiple collision angles are then combined to determine various real-vehicle collision scenarios.

[0050] For example, multiple collision zones include: side collision zone, rear collision zone, and front collision zone. Multiple collision types include: frontal collision, side collision, tipping collision, and impact collision. Multiple collision objects include: bicycles, electric vehicles, motorcycles, other vehicles, and road obstacles. Multiple collision speeds can be set in a stepped manner, such as: 0 km / h, 5 km / h, 10 km / h, 20 km / h, etc. Multiple collision angles include: the angle between the collision object and the collision vehicle is ±30°, ±60°, or 90°.

[0051] For example, a defined real-vehicle collision scenario includes at least one of the following: Real-vehicle collision scenario one: A bicycle collides head-on with the vehicle at a collision speed of 5 km / h at a 90° angle to the vehicle's frontal collision area. Real-vehicle collision scenario two: An electric bicycle collides laterally with the vehicle at a collision speed of 10 km / h at a +60° angle to the vehicle's frontal collision area. Real-vehicle collision scenario three: A motorcycle collides laterally with the vehicle at a collision speed of 20 km / h at a +30° angle to the vehicle's frontal collision area. Combining these multiple collision areas, collision methods, collision objects, collision speeds, and collision angles can determine various real-vehicle collision scenarios; further examples are not provided here.

[0052] Step 1011B: Obtain the maximum simulated real-vehicle trigger value of the collision vehicle when the gravity sensor is triggered in each real-vehicle collision scenario.

[0053] In practice, the collision vehicle determines the simulated trigger value for the gravity sensor in each real-vehicle collision scenario and sends this simulated trigger value to the vehicle collision trigger parameter simulation device. The collision vehicle undergoes real-vehicle collisions in multiple scenarios, determines multiple simulated trigger values, and sends these multiple simulated trigger values ​​to the vehicle collision trigger parameter simulation device.

[0054] The vehicle collision trigger parameter simulation device receives multiple simulated real-vehicle trigger values ​​from the colliding vehicle when the gravity sensor is triggered in each real-vehicle collision scenario, and performs data processing on the multiple simulated real-vehicle trigger values ​​to determine the maximum simulated real-vehicle trigger value when the gravity sensor is triggered in each real-vehicle collision scenario.

[0055] For example, in real-vehicle collision scenario one, if multiple simulated trigger values ​​are received at 0.8 km / h, 1.0 km / h, and 1.2 km / h, then the maximum simulated trigger value for real-vehicle collision scenario one is 1.2 km / h. In real-vehicle collision scenario two, if multiple simulated trigger values ​​are received at 1.6 km / h, 1.8 km / h, and 2.0 km / h, then the maximum simulated trigger value for real-vehicle collision scenario two is 2.0 km / h. In real-vehicle collision scenario three, if multiple simulated trigger values ​​are received at 2.4 km / h, 2.6 km / h, and 2.8 km / h, then the maximum simulated trigger value for real-vehicle collision scenario three is 2.8 km / h.

[0056] Step 1011C: Determine the target real-vehicle collision scenario from the multiple real-vehicle collision scenarios, and use the maximum real-vehicle simulation trigger value corresponding to the target real-vehicle collision scenario as the second collision trigger value.

[0057] In practice, a target real-vehicle collision scenario is determined based on the degree of damage to the vehicles in various real-vehicle collision scenarios, and the maximum simulated real-vehicle trigger value corresponding to the target real-vehicle collision scenario is used as the second collision trigger value. The target real-vehicle collision scenario can be the collision scenario corresponding to the maximum degree of damage to the vehicles among various real-vehicle collision scenarios.

[0058] For example, the maximum simulated real-vehicle trigger speed for real-vehicle collision scenario one is 1.2 km / h, for real-vehicle collision scenario two it is 2.0 km / h, and for real-vehicle collision scenario three it is 2.8 km / h. Based on the different degrees of damage to the vehicles in real-vehicle collision scenarios one, two, and three, real-vehicle collision scenario three is determined as the target real-vehicle collision scenario. Therefore, the second collision trigger speed is determined to be the maximum simulated real-vehicle trigger speed of real-vehicle collision scenario three, which is 2.8 km / h.

[0059] The above approach, by conducting real-vehicle collisions, makes the determined second collision trigger value more accurate. This allows for the determination of the corresponding setting parameters for simulating collision scenarios using the second collision trigger value, resulting in more accurate setting parameters. Furthermore, during real-vehicle collisions, multiple real-vehicle collision scenarios are determined, and the second collision trigger value is determined based on the maximum real-vehicle simulation trigger value corresponding to each scenario, which further improves the accuracy of the second collision trigger value.

[0060] In some embodiments, step 1012 includes:

[0061] Step 1012A: Control the collision simulation object to simulate a collision scenario for the collision vehicle, and obtain the object trigger value triggered by the collision vehicle under the collision scenario simulated by the collision simulation object.

[0062] In practice, the collision vehicle determines the object trigger value when the gravity sensor is triggered under each collision scenario simulation, and sends the object trigger value to the vehicle collision trigger parameter simulation device. The collision simulation object is controlled to simulate multiple collision scenarios with different parameter information. The collision vehicle determines multiple object trigger values ​​and sends these multiple object trigger values ​​to the vehicle collision trigger parameter simulation device.

[0063] The vehicle collision trigger parameter simulation device receives multiple object trigger values ​​from the colliding vehicle, and compares these multiple object trigger values ​​with a second collision trigger value to determine the setting parameters for simulating the collision scenario.

[0064] Step 1012B: In response to determining that the difference between the object trigger value and the second collision trigger value is less than or equal to a preset trigger value threshold, the parameter information corresponding to the collision simulation object when simulating a collision scene is used as the setting parameter.

[0065] In practice, the difference between the object trigger value and the second collision trigger value is processed. When the difference between the object trigger value and the second collision trigger value is less than or equal to the preset trigger value threshold, that is, the object trigger value and the second collision trigger value are close, it means that the collision simulation object is close to the actual vehicle collision scenario. Then, the parameter information of the collision simulation object corresponding to the object trigger value is used as the setting parameter.

[0066] In addition, after processing the difference between the object trigger value and the second collision trigger value, the absolute value of the difference can be processed. When the absolute value of the difference between the object trigger value and the second collision trigger value is less than or equal to a preset trigger value threshold, the parameter information corresponding to the collision simulation object during the collision scene simulation is used as the setting parameter.

[0067] In addition, multiple object trigger values ​​can be compared with the second collision trigger value to obtain multiple differences. The smallest difference among these multiple differences is taken as the target difference. That is, the target object trigger value corresponding to the target difference is closest to the second collision trigger value. This means that the collision simulation object corresponding to the target object trigger value is closest to the real vehicle collision scenario. Therefore, the parameter information of the collision simulation object corresponding to the target object trigger value when performing the collision scenario simulation is used as the setting parameter.

[0068] For example, when the collision simulation object is a collision pendulum, the second collision trigger value is 2.8 km / h, the object trigger value triggered by the colliding vehicle in the collision pendulum simulation scenario is 2.7 km / h, and the preset trigger value threshold is 0.2 km / h. The parameters corresponding to the collision pendulum simulation scenario include: the target mass of the collision pendulum is 5 kg, the target pendulum length is 10 cm, and the target swing angle is 60°. Since the difference between the second collision trigger value and the object trigger value is 2.8 km / h - 2.7 km / h = 0.1 km / h, which is less than the preset trigger value threshold of 0.2 km / h, the target mass of 5 kg, the target pendulum length of 10 cm, and the target swing angle of 60° are used as the setting parameters for the collision pendulum.

[0069] The above method involves determining the object trigger value closest to the second collision trigger value, and then using the parameter information of the collision simulation object corresponding to that object trigger value as the setting parameter. In this way, the determined setting parameter of the collision simulation object can accurately simulate real-vehicle collision scenarios, thereby accurately determining the first collision trigger value.

[0070] In some embodiments, step 101 includes:

[0071] Step 101A: Based on predetermined setting parameters, control the collision simulation object to perform multiple collision scenario simulations on the target vehicle, and obtain multiple object simulation trigger values ​​when the gravity sensor of the target vehicle is triggered under multiple collision scenario simulations.

[0072] In practice, based on the set parameters, the collision simulation object is controlled to simulate multiple collision scenarios with the target vehicle. The target vehicle determines the simulated trigger values ​​of multiple objects when the gravity sensor is triggered under multiple collision scenario simulations, and sends the simulated trigger values ​​of multiple objects to the vehicle collision trigger parameter simulation device.

[0073] For example, when the collision simulation object is a collision pendulum, the determined settings are the target mass, target pendulum length, and target swing angle of the collision pendulum. The collision pendulum is controlled to simulate multiple collision scenarios with the target vehicle using the target mass, target pendulum length, and target swing angle. The target vehicle determines multiple simulated trigger values ​​for the gravity sensor when it is triggered in multiple collision scenario simulations, and sends these multiple simulated trigger values ​​to the vehicle collision trigger parameter simulation device.

[0074] In addition, collisions can be performed on different collision areas of the vehicle based on the set parameters to determine multiple collision scenario simulations. The target vehicle determines multiple object simulation trigger values ​​when the gravity sensor is triggered under multiple collision scenario simulations, and sends the multiple object simulation trigger values ​​to the vehicle collision trigger parameter simulation device.

[0075] For example, the predetermined settings are a target mass of 5kg, a target pendulum length of 10cm, and a target swing angle of 60°. The collision pendulum with a target mass of 5kg and a target pendulum length of 10cm is controlled to swing at the target swing angle of 60°, thereby simulating a collision scenario with the target vehicle. This makes the simulated collision scenario more closely resemble a real-world collision, resulting in a more accurate determination of the first collision trigger value. Furthermore, it eliminates the need for a real-world collision with the target vehicle, thus avoiding damage to the target vehicle.

[0076] Step 101B: Perform data selection processing on the simulated trigger values ​​of the multiple objects to obtain the first collision trigger value.

[0077] In practice, the simulated trigger values ​​of multiple objects obtained from multiple collision scenario simulations are processed to select the first collision trigger value. For example, the simulated trigger values ​​of multiple objects are filtered to remove those with large differences, and the average of the filtered simulated trigger values ​​is then applied to obtain the first collision trigger value.

[0078] The above approach involves performing multiple collision scenario simulations on the vehicle based on set parameters to determine multiple object simulation trigger values, or performing multiple collision scenario simulations on different collision areas of the vehicle based on set parameters to determine multiple object simulation trigger values. These multiple object simulation trigger values ​​are then processed through data selection to obtain the first collision trigger value. This method, based on multiple collision scenario simulations, makes the determined first collision trigger value more accurate and eliminates randomness. Furthermore, simulating collision scenarios based on set parameters does not require actual collisions with the target vehicle, thus avoiding damage to the target vehicle and ensuring the accuracy of the first collision trigger value while preventing damage to the target vehicle.

[0079] In some embodiments, when correcting the first collision trigger value to obtain the target trigger value, this embodiment preferably corrects the first collision trigger value based on the natural trigger value corresponding to the natural environment to obtain the target trigger value. Specifically, step 102 includes:

[0080] Step 1021: Compare the first collision trigger value and the natural trigger value, and determine the target trigger value corresponding to the gravity sensor of the target vehicle based on the comparison result; wherein, the natural trigger value is the trigger value corresponding to the gravity sensor of the target vehicle in a natural environment.

[0081] In practice, the first collision trigger value is the trigger value when the gravity sensor of the target vehicle is triggered in a collision scenario. The natural trigger value is the trigger value when the gravity sensor of the target vehicle is triggered in a natural environment. The natural environment refers to environments that generate collision forces on the vehicle, such as windy or rainy / snowy conditions.

[0082] The first collision trigger value and the natural trigger value are compared and the target trigger value corresponding to the gravity sensor of the target vehicle is determined based on the comparison result.

[0083] When the first collision trigger value is greater than or equal to the natural trigger value, the first collision trigger value is used as the target trigger value. At this time, the target trigger value is greater than or equal to the natural trigger value, so the collision force generated on the target vehicle in the natural environment will not trigger the gravity sensor.

[0084] When the first collision trigger value is less than the natural trigger value, if this first collision trigger value is used as the target trigger value, and since the target trigger value is also less than the natural trigger value, the collision force generated by the vehicle under natural conditions will trigger the gravity sensor. Therefore, the first collision trigger value is corrected to ensure that the corrected first collision trigger value is greater than or equal to the natural trigger value, and this corrected first collision trigger value is used as the target trigger value. This avoids the situation where the collision force generated by the target vehicle under natural conditions triggers the target vehicle's gravity sensor.

[0085] The above solution compares the first collision trigger value in a collision scenario with the natural trigger value in a natural environment, and determines the target trigger value based on the comparison result. This makes the determined target trigger value more accurate, as it is determined by combining the first collision trigger value and the natural trigger value, taking into account the influence of the natural environment on the triggering of the gravity sensor. By calibrating the target vehicle's gravity sensor with the target trigger value, the triggering of the target vehicle's gravity sensor in a natural environment can be avoided, while ensuring that the target vehicle's gravity sensor is triggered in a collision scenario. This improves the sensitivity of the target vehicle's gravity sensor and ensures a good user experience.

[0086] In some embodiments, step 1021 includes:

[0087] Step 1021A: Compare the first collision trigger value and the natural trigger value to obtain the comparison result.

[0088] In practice, the first collision trigger value and the natural trigger value are compared to obtain the comparison result. Based on the comparison result, the target trigger value is determined more accurately, avoiding the influence of the natural trigger value on the vehicle's gravity sensor under natural conditions, and avoiding the situation where the gravity sensor is triggered under natural conditions.

[0089] Step 1021B: In response to determining that the comparison result is that the first collision trigger value is greater than or equal to the natural trigger value, the first collision trigger value is used as the target trigger value.

[0090] In practice, when the first collision trigger value is greater than or equal to the natural trigger value, the first collision trigger value is used as the target trigger value. At this time, the target trigger value is greater than or equal to the natural trigger value, so the collision force generated on the target vehicle in the natural environment will not trigger the gravity sensor.

[0091] Step 1021C: In response to determining that the comparison result is that the first collision trigger value is less than the natural trigger value, the first collision trigger value is corrected to obtain the target trigger value.

[0092] In practice, when the first collision trigger value is less than the natural trigger value, if the first collision trigger value is used as the target trigger value, and this target trigger value is also less than the natural trigger value, the collision force generated by the vehicle under natural conditions will trigger the gravity sensor. Therefore, the first collision trigger value is corrected to ensure that the corrected first collision trigger value is greater than or equal to the natural trigger value, and this corrected first collision trigger value is used as the target trigger value. This avoids the situation where the collision force generated by the target vehicle under natural conditions triggers the target vehicle's gravity sensor.

[0093] Specifically, the process of correcting the first collision trigger value to obtain the target trigger value is as follows: the first collision trigger value is processed according to a preset gradient value; the gradient value is added to the first collision trigger value to obtain the corrected first collision trigger value; in response to determining that the corrected first collision trigger value is less than the natural trigger value, the gradient value is further added to the corrected first collision trigger value; in response to determining that the corrected first collision trigger value is greater than or equal to the natural trigger value, the corrected first collision trigger value is used as the target trigger value.

[0094] The above scheme compares the first collision trigger value in a collision scenario with the natural trigger value in a natural environment, making the determined target trigger value more accurate and avoiding the gravity sensor being triggered in a natural environment. When the first collision trigger value is less than the natural trigger value, it is corrected based on a preset gradient value to determine the target trigger value. This avoids the gravity sensor being triggered by the natural environment while also preventing the target trigger value from being too large, thus ensuring the accuracy of the target trigger value.

[0095] In some embodiments, prior to step 1021, the method further includes:

[0096] Step 1021a: Obtain the first natural trigger value of the target vehicle when the gravity sensor is triggered in any natural environment.

[0097] In practice, the natural environment refers to an environment that generates collision forces on vehicles, such as windy conditions or rainy / snowy conditions. The natural environment includes at least one of the following: windy conditions, rainy conditions, and snowy conditions.

[0098] The target vehicle determines a first natural trigger value when the gravity sensor is triggered within a preset time period under any natural environment, and sends the first natural trigger value to the vehicle collision trigger parameter simulation device. For example, with a preset time period of 0.5 hours, the target vehicle determines multiple first natural trigger values ​​when the gravity sensor is triggered under windy, rainy, and snowy conditions for 0.5 hours respectively, and sends the multiple first natural trigger values ​​to the vehicle collision trigger parameter simulation device.

[0099] Step 1021b: Obtain the second natural trigger value of the target vehicle when the gravity sensor is triggered under at least two natural environments.

[0100] In practice, the target vehicle determines a second natural trigger value for the gravity sensor under at least two different natural environments within a preset time period, and sends this second natural trigger value to the vehicle collision trigger parameter simulation device. For example, with a preset time period of 0.5 hours, the target vehicle determines the second natural trigger value for the gravity sensor under both windy and rainy conditions for 0.5 hours, and sends this second natural trigger value to the vehicle collision trigger parameter simulation device. Furthermore, there are multiple combinations of at least two natural environments, thus allowing for the determination of multiple second natural trigger values. Examples of combinations of at least two natural environments are not detailed here.

[0101] Step 1021c: Determine the maximum value from the first natural trigger value and the second natural trigger value as the natural trigger value.

[0102] In practice, the vehicle collision triggering parameter simulation device determines the maximum value from multiple first natural triggering values ​​and multiple second natural triggering values ​​sent by the target vehicle as the natural triggering value.

[0103] The above scheme determines a first natural trigger value under one natural environment and at least two second natural trigger values ​​under two different natural environments, comprehensively considering the triggering of the gravity sensor by various natural environmental scenarios. The maximum value among multiple first and second natural trigger values ​​is selected as the natural trigger value, making the determined natural trigger value more accurate.

[0104] Through the above embodiments, by controlling a collision simulation object to simulate a collision scenario with the target vehicle, the first collision trigger value of the target vehicle's gravity sensor under the collision scenario can be accurately determined. This makes the first collision trigger value more consistent with the trigger value of the gravity sensor under the collision scenario, and it eliminates the need for a real-vehicle collision, thus avoiding damage to the target vehicle. Based on the first collision trigger value, the target trigger value corresponding to the target vehicle's gravity sensor is determined, making the determined target trigger value more accurate. In this way, after calibrating the target vehicle's gravity sensor with the target trigger value, it can be guaranteed that the target vehicle's gravity sensor will be triggered under the collision scenario, thereby improving the sensitivity of the target vehicle's gravity sensor and ensuring a good user experience.

[0105] It should be noted that the embodiments of this disclosure can also be further described in the following ways:

[0106] This embodiment mainly includes: (1) verifying the influence of the natural environment on the G-sensor sensor under actual vehicle conditions and determining the natural trigger value; (2) simulating collision scenarios in real life to determine the G-sensor alarm scenario and determining the second collision trigger value; (3) determining the setting parameters of the collision pendulum corresponding to the alarm scenario through the G-sensor sensor trigger value; and (4) using tooling to calibrate the target trigger value for the target vehicle of subsequent models. The following will be described in detail with reference to the accompanying drawings and working process:

[0107] (a) Determine the natural trigger value.

[0108] Reverse verification of the impact of the natural environment on the G-sensor sensor under real vehicle conditions: Under real vehicle conditions, a single or combined external natural environment (such as wind, rain, etc.) continuously acts on the entire vehicle for 0.5 hours, and record multiple first natural trigger values ​​and multiple second natural trigger values ​​collected by the G-sensor sensor. The maximum value among the multiple first natural trigger values ​​and multiple second natural trigger values ​​is determined as the natural trigger value.

[0109] (ii) Determine the second collision trigger value.

[0110] The system simulates real-life collision scenarios to determine the triggering conditions for the G-sensor alarm. This involves simulating various collision types, including frontal, side, tipping, and impact collisions, using vehicles as targets. Specifically, collisions are conducted with bicycles, electric bikes, motorcycles, other vehicles, and road obstacles at progressively higher speeds (0 km / h, 5 km / h, 10 km / h, 20 km / h) and angles (±30°, ±60°, 90°). The maximum values ​​reached by the G-sensor under each scenario are determined. Based on the vehicle damage and reverse verification, the system identifies the collision scenario that should trigger the alarm, using the determined maximum value as the secondary collision trigger value.

[0111] The actual collision area of ​​the vehicle is as follows Figure 3A , Figure 3B and Figure 3C As shown. Figure 3A This is a schematic diagram of the vehicle side collision area according to an embodiment of the present disclosure. The vehicle side collision area is located on the side of the vehicle body, and the location of the vehicle side collision area includes the door area, the area above the wheel, and the areas on the left and right sides of the wheel. Figure 3B This is a schematic diagram of the rear-end collision area of ​​a vehicle according to an embodiment of the present disclosure. The rear-end collision area is located at the rear of the vehicle and includes the area near the taillights and the tailgate area. The rear-end collision area is symmetrically arranged about the center of the vehicle. Figure 3C This is a schematic diagram of the front collision area of ​​a vehicle according to an embodiment of the present disclosure. The front collision area is located in front of the vehicle and includes the area near the headlights. The front collision area is symmetrically arranged about the center of the vehicle.

[0112] (III) Determine the setting parameters.

[0113] The setting parameters of the collision pendulum corresponding to the alarm scenario are determined by the second collision trigger value: Different collision areas are selected in the full vehicle collision test area, and the pendulum mass, pendulum length, and swing angle are adjusted to subject multiple collision areas to free fall impacts. The object trigger value when the G-sensor is triggered under the free fall impact of the collision pendulum is determined until the object trigger value is close to the second collision trigger value. The corresponding pendulum mass, pendulum length, and swing angle are then used as the setting parameters. Multiple impacts are performed to ensure effectiveness, and the final setting parameters of the collision pendulum are determined.

[0114] (iv) Determine the target trigger value.

[0115] The target trigger value is calibrated for subsequent target vehicles using a collision pendulum: Using predetermined collision pendulum settings, multiple impact tests are conducted on target vehicles of other models with different vehicle architectures or ECU placements in various collision zones. Multiple first-collision trigger values ​​are recorded for each collision zone, and the average value is taken from each collision zone to eliminate randomness, resulting in an averaged first-collision trigger value. This first-collision trigger value is compared with the natural trigger value, and the target trigger value is determined based on the comparison result.

[0116] Through the above embodiments, the impact values ​​of single and complex natural environments on the G-sensor are collected under real-vehicle conditions. Various collision scenarios are simulated to jointly confirm the collision settings corresponding to the vehicle damage state. The G-sensor trigger value is calibrated in sentinel mode for target vehicles of different vehicle architectures or ECU placements using the collision pendulum setting parameters. By simulating collision scenarios based on the collision pendulum setting parameters, actual vehicle collisions are not required, thus avoiding damage to the target vehicle and ensuring the accuracy of the first collision trigger value while preventing damage to the target vehicle.

[0117] It should be noted that the method of this disclosure embodiment can be executed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this disclosure embodiment, and the multiple devices will interact with each other to complete the method described.
