Description

Technical Field

[0001] The present application relates to the field of vehicle safety technology, and in particular to a verification method and device for an active hood with active safety identification capability. Background Art

[0002] In order to reduce the head injury of pedestrians in actual collision accidents, vehicles will use active hoods. Active hoods monitor the collision situation of the front of the vehicle through sensors, and automatically pop up the hood to protect the pedestrian's head and reduce collision damage when potential collision risks are detected. If the system misjudges, it may cause the hood to explode by mistake. After the active hood explodes by mistake, it usually needs to be repaired or replaced, which may incur high costs. Especially for luxury models or vehicles equipped with advanced safety systems, the repair cost may be higher.

[0003] In the related technology, in order to reduce the possibility of accidental explosion of the active hood, the vehicle pedestrian detection function can be introduced into active safety. First, the camera sensor is used to identify whether the object in front is a pedestrian. The explosion threshold of the camera sensor is adjusted to lower the explosion threshold of pedestrian accidents, making it easier for the vehicle to identify that the impact object is a pedestrian. Conversely, the explosion threshold is raised when colliding with non-pedestrian objects. Alternatively, when the vehicle identifies that the impact object is a pedestrian and the collision cannot be avoided, the active hood can be deployed before the collision to buffer the pedestrian impact energy.

[0004] However, in the related technologies, whether it is through the method of adjusting the detonation threshold or through the active identification method, it mainly relies on the active safety identification capability of the vehicle. The existing technical solutions do not fully consider the active safety identification capability of the vehicle, resulting in the product not having the safety function certification capability during the promotion and application process, which is in urgent need of improvement. Summary of the invention

[0005] The present application provides a verification method and device for an active hood with active safety recognition capability, in order to solve the problem that the active safety recognition capability of the vehicle is not fully considered in the related technology, resulting in the product not having the safety function certification capability during the promotion and application process.

[0006] A first aspect of the present application provides a method for verifying an active hood with active safety identification capability, comprising the following steps: obtaining type information of the active hood with active safety identification capability, and collecting operating condition signals and impact signals of the active hood during verification; generating a verification system for the active hood based on the type information, the operating condition signals and the impact signals; and using the verification system to generate verification results when the active hood is verified.

[0007] Through the above technical scheme, a verification system for the active hood can be generated according to the type information of the active hood with active safety identification capability, the operating condition signal and the impact signal of the active hood during verification, and then the verification result of the active hood during verification can be obtained. By obtaining accurate active hood type information, comprehensive operating condition signals and impact signals, a targeted verification system can be generated to improve the accuracy and reliability of the verification, ensure that the verification process can be carried out according to the actual characteristics of the hood, ensure that the verification process can be executed more efficiently, improve the overall efficiency of the verification work, and proactively discover the deficiencies in the design and performance of the active hood, so that the product has the ability to obtain safety function certification during the promotion and application process.

[0008] Optionally, in one embodiment of the present application, the verification system for generating the active hood based on the type information, the operating condition signal and the impact signal includes: when the type information contains perception adjustment information, extracting a pedestrian signal, a non-pedestrian signal or an unknown signal from the operating condition signal, and extracting an impact speed and / or an impact type from the impact signal; determining a verification detonation threshold of the active hood based on the unknown signal; adjusting the verification detonation threshold based on the pedestrian signal or the non-pedestrian signal, in combination with the impact speed and / or the impact type, to obtain a target detonation value of the active hood, and generating the verification system based on the adjustment information of the verification detonation threshold and the target detonation value.

[0009] Through the above technical scheme, the verification detonation threshold can be adjusted according to the pedestrian signal, non-pedestrian signal or unknown signal in the operating condition signal and the impact speed and / or impact type in the impact signal while including the perception adjustment information, so as to obtain the target detonation value of the active hood and finally generate a verification system. By extracting the operating condition signal and the impact signal while including the perception adjustment information, a more targeted verification system can be generated, which can more accurately simulate and evaluate the performance of the active hood in actual use, thereby improving the accuracy and credibility of the verification results.

[0010] Optionally, in one embodiment of the present application, the verification system for generating the active hood based on the type information, the operating condition signal and the impact signal includes: when the type information contains active safety information, obtaining a verification matrix of the active hood using the operating condition signal and the impact signal; calculating verification scores under different operating conditions in the operating condition signal based on the verification matrix; and calculating the verification score of the total operating condition in the operating condition signal based on the verification scores under the different operating conditions, so as to generate the verification system using the verification score of the total operating condition.

[0011] Through the above technical scheme, in the case of including active safety information, a verification matrix can be first constructed using the operating condition signal and the impact signal, and then the verification scores under different operating conditions in the operating condition signal are calculated, and then the verification score of the total operating condition in the operating condition signal is calculated, and then the verification system is obtained. By integrating the operating condition signal and the impact signal to construct a verification matrix, the verification process is more quantitative and the results are more convincing. It can more clearly demonstrate the response of the active hood under different operating conditions and impact conditions, improve the scientificity and systematicness of the verification system, and enhance the accuracy and reliability of the verification results.

[0012] Optionally, in one embodiment of the present application, the calculation formula of the verification score of the total working condition may be, but is not limited to,:

[0013] T=(C1*condition 1+C2*condition 2+...+CN*condition N) / N,

[0014] Among them, CN is the scaling factor and N is the total number of working conditions participating in the calculation.

[0015] Through the above technical scheme, the verification score of the total working condition can be obtained according to the weighted value of the verification scores under different working conditions in the working condition signal, so that the verification score of the total working condition is more in line with the actual situation, thereby improving the comprehensiveness and accuracy of the verification score, and the scaling factor of each working condition can be flexibly adjusted according to actual needs, thereby enhancing the flexibility and adaptability of the verification system, making the verification process more standardized and unified, facilitating data analysis and visualization, providing strong support for decision-making, and providing clear direction and goals for subsequent optimization and improvement.

[0017] Through the above technical scheme, after generating the verification system, the actual type information, actual working condition signal and actual impact signal of the active hood can be re-acquired, and the corresponding verification result can be quickly obtained. According to the different actual type information, the corresponding verification system is adopted to optimize the verification process, improve the verification efficiency, and make the verification process more targeted, which can more accurately reflect the actual performance of the active hood under different conditions, make the verification results more comprehensive and reliable, and improve the accuracy and reliability of the verification results.

By obtaining accurate active hood type information, comprehensive operating condition signals and impact signals, a targeted verification system can be generated to improve the accuracy and reliability of the verification, ensure that the verification process can be carried out according to the actual characteristics of the hood, ensure that the verification process can be executed more efficiently, improve the overall efficiency of the verification work, and proactively discover the deficiencies in the design and performance of the active hood, so that the product has the ability to obtain safety function certification during the promotion and application process.

[0021] Through the above technical scheme, the verification detonation threshold can be adjusted according to the pedestrian signal, non-pedestrian signal or unknown signal in the operating condition signal and the impact speed and / or impact type in the impact signal while including the perception adjustment information, so as to obtain the target detonation value of the active hood and finally generate a verification system. By extracting the operating condition signal and the impact signal while including the perception adjustment information, a more targeted verification system can be generated, which can more accurately simulate and evaluate the performance of the active hood in actual use, thereby improving the accuracy and credibility of the verification results.

By integrating the operating condition signal and the impact signal to construct a verification matrix, the verification process is more quantitative and the results are more convincing. It can more clearly demonstrate the response of the active hood under different operating conditions and impact conditions, improve the scientificity and systematicness of the verification system, and enhance the accuracy and reliability of the verification results.

[0024] Optionally, in one embodiment of the present application, the calculation formula of the verification score of the total working condition may be, but is not limited to,:

[0028] Optionally, in one embodiment of the present application, the second generation module includes: a second acquisition unit, used to re-acquire the actual type information of the active hood based on the verification system, and collect the actual operating condition signal and the actual impact signal of the active hood during verification; a third generation unit, used to obtain the verification result based on the actual operating condition signal and the actual impact signal, combined with the adjustment information of the verification detonation threshold and the target detonation value in the verification system, when the actual type information contains perception adjustment information; a fourth generation unit, used to obtain the verification result based on the actual operating condition signal and the actual impact signal, combined with the verification score in the verification system, when the actual type information contains active safety information.

DETAILED DESCRIPTION

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0047] The following describes the verification method and device of the active hood with active safety recognition capability of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the active safety recognition capability of the vehicle is not fully considered, resulting in the product not having the safety function certification capability during the promotion and application process, the present application provides a verification method of the active hood with active safety recognition capability, in which the verification system of the active hood can be generated according to the type information of the active hood with active safety recognition capability, the working condition signal and the impact signal of the active hood during the verification, and then the verification result of the active hood during the verification is obtained, by obtaining accurate active hood type information, comprehensive working condition signal and impact signal, and then generating a targeted verification system, improving the accuracy and reliability of the verification, ensuring that the verification process can be carried out according to the actual characteristics of the hood, ensuring that the verification process can be performed more efficiently, improving the overall efficiency of the verification work, and actively discovering the deficiencies in the design and performance of the active hood, so that the product has the safety function certification capability during the promotion and application process. Thus, the problem that the active safety recognition capability of the vehicle is not fully considered in the related technology, resulting in the product not having the safety function certification capability during the promotion and application process is solved.

[0048] Before introducing the verification method of the active hood with active safety identification capability proposed in the embodiment of the present application, an explanation will be given of a verification system of an active pop-up hood involved in the embodiment of the present application.

[0049] Specifically, Figure 1 The present invention is a block diagram of a verification system for an active pop-up hood provided according to an embodiment of the present application.

[0050] like Figure 1 As shown, the active pop-up hood verification system 10 includes: a control system 101 , a signal generation system 102 , a test vehicle 103 and different types of impactors 104 .

[0051] The control system 101 can control the firing speeds of different types of impactors 104 and the output signals of the signal generating system 102 .

[0052] The signal generating system 102 is connected to the test vehicle 103 to realize the function of inputting pedestrian signals, non-pedestrian signals or unknown signals.

[0053] Specifically, Figure 2 The present invention is a flowchart of a verification method of an active hood with active safety identification capability provided according to an embodiment of the present application.

[0054] like Figure 2 As shown, the verification method of the active hood with active safety recognition capability includes the following steps:

[0055] In step S201, the type information of the active hood with active safety identification capability is obtained, and the working condition signal and the impact signal of the active hood during verification are collected.

[0056] It can be understood that the embodiments of the present application can divide the active hood into two categories according to the functional type of the active hood with active safety identification capability, and establish different verification systems for different functional types, one is an active hood based on perception adjustment, and the other is an active hood based on active safety.

[0057] Furthermore, in the embodiments of the present application, the operating condition signal may include but is not limited to: pedestrian signals, non-pedestrian signals and unknown signals, which may be specifically set by technicians in this field according to actual conditions, and the present application does not impose any specific restrictions.

[0058] Further, in the embodiment of the present application, the impact signal may include but is not limited to: impact speed and impact type, which may be generated by different types of impactors, which may include but are not limited to: Flex-PLI (Flexible Pedestrian Legform Impactor) leg impactor, aPLI (advanced Pedestrian Legform Impactor) leg impactor and PDI-2 impactor, etc., which may be specifically set by those skilled in the art according to actual conditions, and this application does not make any specific restrictions.

[0059] As a possible implementation method, the active hood with active safety identification capability in the embodiment of the present application can collect various operating condition signals and impact signals based on the type information of the active hood during verification, thereby ensuring the normal operation of the active hood and the accuracy of the verification.

[0060] In step S202, a verification system of the active hood is generated according to the type information, the operating condition signal and the impact signal.

[0061] In the actual implementation process, in order to generate a verification system for the active hood, the embodiment of the present application can comprehensively consider type information, operating condition signals, impact signals, etc. The specific content will be introduced in detail below and will not be elaborated here.

[0062] Optionally, in one embodiment of the present application, a verification system for an active hood is generated based on type information, operating condition signals and impact signals, including: when the type information includes perception adjustment information, extracting pedestrian signals, non-pedestrian signals or unknown signals from the operating condition signals, and extracting impact speed and / or impact type from the impact signals; determining a verification detonation threshold of the active hood based on the unknown signal; adjusting the verification detonation threshold based on the pedestrian signal or the non-pedestrian signal, in combination with the impact speed and / or impact type, to obtain a target detonation value of the active hood, and generating a verification system based on the adjustment information of the verification detonation threshold and the target detonation value.

[0063] In some embodiments, when the type information includes the perception adjustment information, the verification system of the active hood generated according to the type information, the working condition signal and the impact signal can be understood as follows: the embodiment of the present application can combine different types of impactors with working condition signals, and then build a test matrix, and use whether the active hood is detonated and the adjustment information of the verification detonation threshold recorded by the EDR (Event Data Record) system as evaluation indicators to establish a corresponding verification system, the main contents of which may include:

[0064] In an embodiment of the present application, the vehicle manufacturer may provide an input operating condition signal port for the vehicle, and the detection mechanism may select the input signal device according to the operating condition signal port, thereby enabling the input signal to be recognized by the vehicle processor and obtaining a pedestrian signal, a non-pedestrian signal or an unknown signal in the operating condition signal.

[0065] Furthermore, the embodiments of the present application can utilize the Flex-PLI leg-shaped impactor, the aPLI leg-shaped impactor and the PDI-2 impactor with different input signals to form a test matrix, thereby simulating various working conditions in actual road accidents, and using the adjustment information of the detonation threshold and whether the hood detonates as the basis for judgment, and verifying the qualification of the active hood containing the perception adjustment information according to the test matrix, thereby obtaining a corresponding verification system.

[0066] For example, in the embodiment of the present application, a block diagram of the active hood adjustment operation logic including the sensing adjustment information is as follows: Figure 3 As shown by Figure 3 It can be seen that the adjustment operation logic of the embodiment of the present application can be divided into three prerequisites. Under normal vehicle driving conditions, the vehicle recognizes that the front impact object may include but is not limited to three types of prerequisites: pedestrians, non-pedestrians, and unknown. The vehicle will adjust the verification detonation threshold to make it easier to be detonated when it hits a pedestrian. When the vehicle recognizes the pedestrian signal and does not adjust the verification detonation threshold, the vehicle hits the pedestrian as the basic condition. Under extreme conditions, when the vehicle recognizes that the front impact object is a non-pedestrian but the actual impact object is a pedestrian, the vehicle will adjust the verification detonation threshold to a high limit. At this time, it is less likely to be detonated when hitting a pedestrian, and it is easy to fail to start.

[0067] Depend on Figure 3 It can be known that the active hood containing perception and adjustment information in the embodiment of the present application should include multiple operating condition signals and multiple impact signals during the functional verification and the generation of the verification system. That is to say, the input of the vehicle identification operating condition signal in the embodiment of the present application may include but is not limited to pedestrian signals, non-pedestrian signals, unknown signals, etc., and the present application does not impose specific restrictions; the corresponding impactor may include but is not limited to PDI-2 impactor, Flex-PLI leg-type impactor, aPLI leg-type impactor, etc., and the present application does not impose specific restrictions. The impact speed selected for the generation of the verification system should also cover multiple speeds, which can be specifically set by technicians in this field according to actual conditions, and the present application does not impose specific restrictions.

[0068] That is to say, when the embodiment of the present application performs functional verification on the active hood containing perception adjustment information, if the vehicle identifies the operating condition signal as an unknown signal, a leg-type PDI-2 impactor is used, the vehicle has no signal input, the impact speed is a low threshold speed, and the detonation threshold is verified to be unchanged, the corresponding position on the front bumper of the vehicle is hit, and the active hood should be detonated; if the vehicle identifies the operating condition signal as a pedestrian signal, a leg-type PDI-2 impactor is used, a pedestrian signal is input, the impact speed is a low threshold speed, and the detonation threshold is verified to be adjusted, the corresponding position on the front bumper of the vehicle is hit, and the active hood should be detonated; if the vehicle identifies the operating condition signal as a non-pedestrian signal, a PDI-2, Flex-PLI or aPLL impactor is used, a non-pedestrian signal is input, the impact speed is a low threshold speed, 40km / h under standard operating conditions, and 50km / h under high-speed operating conditions, and the detonation threshold is verified to be adjusted, the corresponding position on the front bumper of the vehicle is hit, and the active hood should be detonated.

[0069] In addition, it should be noted that in order to ensure that the vehicle can effectively detect pedestrians across the entire width of the bumper, the embodiment of the present application should be verified in the leg test area and at the boundary. In other words, the embodiment of the present application can take braking measures when a collision occurs, and the braking causes the body posture to be inconsistent with the design value. Therefore, in the process of building a verification system, the embodiment of the present application should also consider the functional verification of the vehicle braking posture, and select 1-2 positions for test verification under this posture.

[0070] For example, Figure 4 As shown, the embodiment of the present application provides a flow chart of an active hood generation verification system including perception adjustment information, and its main steps are:

[0071] Step S401: Select different types of impactors.

[0072] Among them, the embodiments of the present application can select different types of impactors for different working condition signals, such as one of the PDI-2 impactor, aPLI leg-type impactor, and Flex-APLI leg-type impactor, and the present application does not make specific restrictions. The impact component is the front bumper of the test vehicle, and the impact position of the PDI-2 impactor can be, but is not limited to, the sensor layout position ±50mm (such as an acceleration sensor, which is not specifically limited in the present application), a position that is prone to produce a large acceleration to the impactor (such as a sensing system without a local sensor, which is not specifically limited in the present application), the middle position of the front bumper of the vehicle, etc., and the present application does not make specific restrictions; the impact position of the PLI leg-type impactor and the Flex-APLI leg-type impactor can be, but is not limited to, the sensor layout position ±50mm (such as an acceleration sensor, which is not specifically limited in the present application), a position that is prone to produce a large acceleration to the impactor (a sensing system without a local sensor, which is not specifically limited in the present application), etc., and the present application does not make specific restrictions.

[0073] Step S402: Determine the impact speed of different types of impactors.

[0074] Among them, the embodiments of the present application can determine different impact speeds for different types of impactors. For example, in the embodiments of the present application, when the aPLI leg-type impactor and the Flex-PLI leg-type impactor are applied, the impact speed can be but is not limited to 40km / h±2km / h, and the present application does not make specific restrictions; when the PDI2 impactor is applied, the impact speed can be divided into two cases according to the input signal, such as less than the low threshold speed of 10 to 15km / h, the low threshold speed, etc., and the present application does not make specific restrictions.

[0075] Step S403: Select different impact speeds according to different working condition signals.

[0076] Among them, the embodiment of the present application can match different impact speeds for different operating condition signals, such as pedestrian signals, non-pedestrian signals or unknown signals. The specific signal and speed matching are shown in Table 1, wherein Table 1 is a matching table of different operating condition signals and different impact speeds provided according to an embodiment of the present application.

[0077] Table 1

[0078]

[0079] Step S404: different collision signals are used for collision.

[0080] Among them, the embodiment of the present application can adjust the test system settings according to different working condition signals and then launch the impactor. In order to ensure that the vehicle can effectively detect pedestrians across the entire bumper width, a verification test should be carried out at the boundary of the leg-type test area.

[0081] Step S405: recording the adjustment information of the verification detonation threshold and the target detonation value to generate a verification system.

[0082] Among them, the embodiment of the present application can read the verification detonation threshold through the EDR system and compare it with the normal standard value, and at the same time check whether the active hood is detonated. The hood detonation situation should be consistent with the verification detonation threshold performance, and its main contents may include:

[0083] In the embodiment of the present application, in test 1, if the vehicle's working condition signal is identified as an unknown signal, a leg-type PDI-2 impactor is used, there is no signal input, the impact speed is a low threshold speed, and the detonation threshold is verified to be unchanged, and the corresponding position on the front bumper of the vehicle is impacted, and the active hood should be detonated;

[0084] In test 2-3, if the vehicle recognizes the working condition signal as a pedestrian signal, a leg-type PDI-2 impactor is used, a pedestrian signal is input, and the impact speed is a low threshold speed. Under the condition that the detonation threshold is adjusted, the active hood should be detonated when the corresponding position on the front bumper of the vehicle is impacted;

[0085] In tests 4-6, if the vehicle is identified as a non-pedestrian signal in the working condition signal, use PDI-2, Flex-APLI, aPLL impactor, input non-pedestrian signal, impact speed is low threshold speed, standard working condition 40km / h, high-speed working condition 50km / h, verify that the detonation threshold is adjusted, and the active hood should be detonated when the corresponding position on the front bumper of the vehicle is hit;

[0086] In Test 7, when a collision occurs, the vehicle will take braking measures. Braking will cause the vehicle body posture to be inconsistent with the design value. The verification plan should also consider the functional verification of the vehicle braking posture. Under this posture, 1-2 positions are selected for test verification to obtain the corresponding verification system.

[0087] Optionally, in one embodiment of the present application, a verification system for an active hood is generated based on type information, operating condition signals, and impact signals, including: when the type information includes active safety information, using the operating condition signals and impact signals to obtain a verification matrix for the active hood; calculating verification scores under different operating conditions in the operating condition signals based on the verification matrix; calculating the verification score of the total operating condition in the operating condition signals based on the verification scores under different operating conditions, so as to generate a verification system using the verification score of the total operating condition. The calculation formula for the verification score of the total operating condition may be, but is not limited to,:

[0088] T=(C1*condition 1+C2*condition 2+...+CN*condition N) / N,

[0089] Among them, CN is the scaling factor and N is the total number of working conditions participating in the calculation.

[0090] In some embodiments, in the case where the type information includes active safety information, the verification system for generating an active hood according to the type information, the operating condition signal and the impact signal can be understood as follows: the active hood including active safety information in the embodiment of the present application can be combined with the AEB test condition to establish a verification score calculation formula for the linear difference, and then select a score area distribution map according to the verification score to generate a corresponding verification system, the main contents of which may include:

[0091] In the embodiment of the present application, when a pedestrian in front is identified and a collision risk is determined, the active hood containing active safety information is deployed in advance, and after the risk contact, the active pop-up hood will retract to its original state. For the evaluation method of the active hood that acts in advance, vehicles equipped with active hoods that are completely based on AEB detection need to undergo two sets of pedestrian protection tests, one with the active hood deployed and one without, and the score is allocated according to the weight of the AEB test conditions.

[0092] Among them, in the embodiment of the present application, the AEB test conditions may include but are not limited to the following situations:

[0093] Case 1: Target object; it may include but is not limited to pedestrians, bicycles, electric vehicles, motorcycles and other passenger vehicles, etc., and this application does not make specific restrictions. Pedestrians may include but are not limited to pedestrians of different age groups and pedestrians of different genders, etc., and this application does not make specific restrictions. Bicycles, electric vehicles, and motorcycles may include but are not limited to two-wheeled vehicles and three-wheeled vehicles, etc., and this application does not make specific restrictions. Passenger vehicles may include but are not limited to vehicles driven or loaded by drivers traveling on the road, etc., and this application does not make specific restrictions.

[0094] Case 2: The relative position of the vehicle and the target object; it may include but is not limited to relative positions at multiple angles such as longitudinal, vertical and diagonal, and this application does not impose any specific restrictions. It may also include but is not limited to a collision between a vehicle and a pedestrian walking longitudinally in front, a collision between a vehicle and a crossing pedestrian, a collision between a vehicle and a pedestrian crossing the road diagonally, etc., and this application does not impose any specific restrictions.

[0095] Case 3: The target object should be in a variety of postures; it may be, but is not limited to, static, walking, and running, etc. This application does not impose any specific restrictions.

[0096] Case 4: The collision position between the vehicle and the target object; it may include but is not limited to multiple collision positions including 10% of the front end structure (i.e. the direction of the vehicle from the main driving seat to the right driving seat), 25% of the front end structure, 40% of the front end structure, 50% of the front end structure, 60% of the front end structure, 75% of the front end structure, 90% of the front end structure, etc., and this application does not make specific restrictions.

[0097] Case 5: Whether there is any obstruction between the vehicle and the target object before the collision occurs; it may include but is not limited to various situations such as no obstruction, semi-obstruction and complete obstruction. This part takes into account complex road conditions (i.e. the condition of obstructions in front of the vehicle's driving direction). It can be specifically set by technicians in this field according to actual conditions, and this application does not impose any specific restrictions.

[0098] Case 6: The environment in which the vehicle and the target object are located; it may include, but is not limited to, various complex working conditions including daytime, nighttime, rainy days, haze, snow, sunny days, etc., and this application does not make specific restrictions, that is, the investigation of the environment on the vehicle AEB detection. Further, the embodiments of this application can match the above-mentioned conditions with each other to obtain a verification matrix of the AEB test conditions, as shown in the schematic diagram Figure 5 shown.

[0099] Furthermore, the embodiment of the present application can be verified by matching the six conditions of the verification matrix in the AEB test condition. During the verification process, the actual road conditions should be restored, and a target object with characteristics should be used as the test object, and each condition should be verified at least 3 times. If the active hood is recognized and deployed in advance 3 times or more, the scoring test will be carried out according to the deployment. Otherwise, the verification is carried out according to the non-deployment method, and the verification result is used as the score under the condition. In addition, in the embodiment of the present application, the verification score of each condition corresponds to a certain weight CN, and then the verification score of the total condition is obtained. The calculation formula of the verification score of the total condition is based on the linear difference calculation, and the calculation formula can be but is not limited to: T = (C1*condition 1+C2*condition 2+...+CN*condition N) / N.

[0107] Among them, the embodiment of the present application can calculate the verification score of the total working condition according to the verification score calculation formula of the total working condition, and then obtain the score of the test vehicle in the AEB active hood part evaluation, thereby generating a verification system.

[0108] In step S203, a verification result of the active hood verification is generated using the verification system.

[0109] It can be understood that in the embodiments of the present application, the verification results may include but are not limited to type information verification results, operating condition signal verification results, collision signal verification results, etc., and the present application does not impose specific limitations.

[0112] As a possible implementation method, after the verification system is generated, when the active hood is verified, the embodiment of the present application can re-acquire the actual type information, actual working condition signal and actual impact signal of the active hood, and then obtain a detailed verification result, which can include but is not limited to the actual type information, actual working condition signal, actual impact signal, adjustment information of the verification detonation threshold, target detonation value, verification score, etc., and the present application does not make specific restrictions.
