Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle testing and verification, and in particular to a digital vehicle testing and verification system. Background Technology
[0002] Vehicle testing is a crucial step in verifying the design performance of general-purpose ground mobility platforms, identifying potential defects, and ensuring their reliability. However, existing technologies suffer from the following core shortcomings: Open-loop verification is inefficient: traditional methods rely on engineers' experience to set operating conditions and manually analyze results. When the test fails to meet the standards, the test plan needs to be adjusted repeatedly, which is time-consuming, costly, and difficult to automate. Multiphysics data fragmentation: Existing systems only collect kinematic parameters (such as velocity and acceleration) or electrical signals, and cannot simultaneously acquire multiphysics coupled response data such as structural strain, heat flow distribution, and electromagnetic environment, which makes it impossible to truly reflect the comprehensive performance of general ground mobile platforms under extreme working conditions; Reliance on historical data leads to the failure of verification of newly developed general-purpose ground mobility platforms: Mainstream data-driven methods (such as statistical models and machine learning) rely on massive amounts of historical fault or usage frequency data. For newly developed general-purpose ground mobility platforms and the first set of general-purpose ground mobility platforms, the lack of such data has caused them to fail, becoming a bottleneck for innovative research and development. The verification conclusions lack quantitative basis: Traditional methods only provide a binary judgment of "pass / fail", which cannot quantify the credibility of the verification conclusions and is difficult to support high-risk engineering decisions.
[0003] Although existing digital twin technology is used in parking lot management, its application is limited to visual monitoring and post-event analysis, and it has failed to build a closed-loop verification system based on physical laws, with real-time observation as input and uncertainty quantification as the driving force.
[0004] Therefore, there is an urgent need for a digital vehicle testing and verification system that does not require historical data, can automatically perform closed-loop optimization, and whose credibility can be quantitatively verified. Summary of the Invention
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art, and provides a digital vehicle testing and verification system.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides a digital vehicle testing and verification system, comprising a test task injection module, a multi-physics field synchronous acquisition module, a physical information fusion modeling module, an uncertainty quantification evaluation module, and a verification result feedback module that are sequentially connected in communication and form a closed-loop feedback loop; The test task injection module is used to receive the performance verification target of the general ground mobility platform from external input, and automatically extract key performance boundary conditions based on the digital mock-up of the general ground mobility platform, convert them into a test constraint set, determine the corresponding test task type, and generate the corresponding executable test parameter set based on the test task type. The multi-physics synchronous acquisition module is used to synchronously acquire multi-physics measured data corresponding to the performance verification target of the general ground mobility platform during the execution of the operating conditions defined by the executable test parameter set on the general ground mobility platform. The physical information fusion modeling module is used to construct a general ground mobility platform behavior proxy model that satisfies the corresponding physical law constraints based on the multi-physics field measured data and the prior design parameters characterizing the inherent physical properties and control logic of the general ground mobility platform, and according to the control equations that match the test task type. The uncertainty quantification and evaluation module is used to perform credibility analysis on the output of the general ground mobility platform behavior agent model and generate credibility indexes for performance verification. The verification result feedback module sends a parameter adjustment instruction to the test task injection module based on the comparison result of the credibility index and the preset threshold, so as to trigger a new round of testing process and realize closed-loop verification.
[0007] In some possible embodiments, the multiphysics measured data includes at least two of the following: structural strain, heat flux distribution, electromagnetic environment, and motion response.
[0008] In some possible embodiments, the physical information fusion modeling module employs a physical information neural network (PINN), whose loss function includes a data fitting term and a partial differential equation residual term: ,in, To measure the physical field output, This is the network prediction value. For sampling points Network parameters The derived partial differential equation residuals, To balance the weights.
[0009] In some possible embodiments, the uncertainty quantification assessment module employs the Monte Carlo Dropout method, performing multiple forward propagations on the same input during the inference phase to obtain the distribution of predicted results, and calculating the 95% confidence interval width based on the distribution of predicted results. The credibility metric used for performance verification is as follows: ,in, and These are the upper and lower 2.5 percentiles of the predicted results.
[0010] In some possible embodiments, when the credibility index is lower than the preset threshold, the verification result feedback module is configured to: send a parameter adjustment instruction to the test task injection module to trigger test reconfiguration; and call the sensitivity analysis submodule to calculate the contribution of each test parameter in the executable test parameter set to the credibility index, identify the test parameter with the largest contribution, and prioritize adjusting the value range of the test parameter.
[0011] In some possible embodiments, when constructing the behavior agent model of the general ground mobility platform, the physical information fusion modeling module does not rely on historical fault records or usage frequency statistics, but only on the physical structure parameters, control logic, and real-time collected multiphysics field observation data of the general ground mobility platform, and models the control equations derived from first principles, thereby supporting the performance verification of newly developed general ground mobility platforms or the first set of general ground mobility platforms without historical operating data.
[0012] In some possible embodiments, the control equations include at least one of the longitudinal dynamics equations of a general ground mobility platform, the thermal diffusion equation of a power battery, or the electromagnetic field equation of a motor, and the type of the control equations is dynamically loaded by the type of the test mission to satisfy the corresponding physical constraints.
[0013] In a second aspect, the present invention provides an electronic device, comprising: One or more processors; A storage unit is used to store one or more programs, which, when executed by one or more processors, enable the one or more processors to implement the digital vehicle testing and verification system described above.
[0014] Thirdly, the present invention provides a computer-readable storage medium having a computer program stored thereon, characterized in that the computer program, when executed by a processor, can realize the digital vehicle testing and verification system described above.
[0015] The digital vehicle testing and verification system of this invention has the following advantages: 1. This invention enables highly reliable verification in scenarios without historical data: The physical information fusion modeling module relies solely on the physical structure parameters, control logic, and real-time multiphysics field measured data of the general-purpose ground mobility platform. Based on the control equations derived from first principles (such as the thermal diffusion equation of the power battery), it constructs a behavioral proxy model of the general-purpose ground mobility platform. It does not require historical fault or usage frequency statistics, thus providing a feasible verification path for newly developed general-purpose ground mobility platforms and the first set of general-purpose ground mobility platforms without historical operating data. 2. This invention can quantitatively verify the conclusions to support engineering decisions: The uncertainty quantification assessment module generates a 95% confidence interval width as a credibility index through Monte Carlo Dropout, transforming the fuzzy "pass / fail" judgment into an objective quantitative assessment, which is conducive to improving the reliability of high-risk engineering decisions; 3. This invention enables efficient closed-loop iteration of the verification process: the verification result feedback module automatically triggers sensitivity analysis based on the credibility index, identifies key test parameters and prioritizes adjusting their value range, avoiding blind trial and error and improving verification efficiency; 4. This invention enables precise integration of design and testing: The test task injection module automatically extracts key performance boundary conditions based on a digital prototype of a general ground mobility platform, converts them into a set of test constraints, and generates a set of executable test parameters, accurately covering the design objectives.

The test task injection module 201 receives externally input performance verification targets for a general-purpose ground mobility platform (e.g., "verifying the power heat source management performance of a certain type of general-purpose ground mobility platform in a -20℃ environment"), and, based on a digital prototype of the general-purpose ground mobility platform... The Mock-up module automatically extracts key performance boundary conditions (such as power heat source heat generation rate of 3.2kW and heat dissipation capacity of 2.8kW), converts them into test constraint sets (such as ambient temperature of -20℃ and power charge / discharge rate of 1C-3C), determines the corresponding test task type, and generates corresponding executable test parameter sets based on the test task type (such as the general ground mobility platform driving sequence: 0-80km / h uniform acceleration, 80km / h uniform speed for 30 minutes, power replenishment strategy: constant current replenishment to 80% capacity); the multi-physics field synchronous acquisition module 202 is used to synchronously acquire data with the general ground mobility platform during the execution of the operating conditions defined in the executable test parameter set (such as 0-80km / h uniform acceleration, 80km / h uniform speed for 30 minutes). The system uses multi-physics field measured data corresponding to the performance verification target; the physical information fusion modeling module 203 is used to construct a general ground mobility platform behavior proxy model that satisfies the corresponding physical law constraints based on the multi-physics field measured data and prior design parameters (including physical structural parameters such as the centroid position of the general ground mobility platform, control logic such as power heat source management strategy, and real-time observation data) characterizing the inherent physical properties and control logic of the general ground mobility platform; the uncertainty quantification evaluation module 204 is used to perform credibility analysis on the output of the general ground mobility platform behavior proxy model (such as the predicted maximum temperature of the power heat source) and generate a credibility index for performance verification; the verification result feedback module 205 is used to perform credibility index and preset threshold (such as...) The comparison results are used to send parameter adjustment instructions (such as "extend the power charge and discharge rate range to 1C-4C") to the test task injection module 205 to trigger a new round of test process and achieve closed-loop verification.
[0025] Specifically, the digital vehicle testing and verification system is deployed in an edge-cloud collaborative architecture. The cloud is responsible for the initial training of the Physical Information Neural Network (PINN), while the edge nodes (deployed in the test site control center) perform real-time inference, uncertainty quantification, and closed-loop feedback control to ensure that the test feedback latency is ≤200ms. The edge node hardware configuration is an NVIDIA Jetson AGX Xavier edge server (8-core CPU / 32-core GPU / 16GB memory), which meets the real-time requirements.
[0026] Specifically, the multi-physics synchronous acquisition module 202 is equipped with a timestamp alignment unit, which uses the IEEE 1588 Precision Time Protocol (PTP) to achieve microsecond-level synchronization, ensuring that sensor data from different physical domains [structural strain (1kHz), heat flow distribution (100Hz), electromagnetic environment (500Hz), and motion response (10Hz) data] are accurately aligned in a unified spatiotemporal coordinate system.
[0027] Specifically, the verification result feedback module 205 generates a digital thread record during the closed-loop process, storing the input parameters, collected data, model output, credibility indicators and reconfiguration decisions of each experiment into the blockchain ledger in an immutable manner, supporting full lifecycle traceable verification and auditing.
[0028] In some embodiments, the measured multiphysics data include at least two of the following: structural strain, heat flux distribution, electromagnetic environment, and motion response (e.g., heat flux distribution of the power heat source and strain of the general ground mobile platform frame structure) to ensure comprehensive capture of the multiphysics coupled response.
[0029] In some embodiments, the physical information fusion modeling module 203 employs a physical information neural network (PINN), whose loss function includes a data fitting term and a partial differential equation residual term: ,in, To measure the physical field output, This is the network prediction value. For sampling points Network parameters The residuals of the derived partial differential equations (such as the residuals of the thermal diffusion equation for power batteries). To balance the weights (such as) =0.7, =0.3).
[0030] In some embodiments, the uncertainty quantification assessment module employs the Monte Carlo Dropout method, performing multiple (preferably 100) forward propagations on the same input during the inference phase to obtain the distribution of predicted results, and calculating the 95% confidence interval width based on the distribution of predicted results. As a credibility indicator for performance verification: ,in, and These are the upper and lower 2.5 percentiles of the predicted results.
[0031] Specifically, in each forward propagation, the Dropout layer of the neural network is randomly activated with a retention rate r (0.5≤r≤0.9, preferably r=0.8) to obtain the distribution of the prediction results.
[0032] In some embodiments, when the credibility index is lower than a preset threshold (e.g., 3°C), the verification result feedback module 205 is configured to: send a parameter adjustment instruction to the test task injection module 201 to trigger test reconfiguration; and call the sensitivity analysis submodule (e.g., Sobol global sensitivity analysis) to calculate the contribution of each test parameter (e.g., charge / discharge rate, ambient temperature) in the executable test parameter set to the credibility index, identify the test parameter with the largest contribution (e.g., power charge / discharge rate contribution of 58%), and prioritize adjusting the value range of the test parameter.
[0033] In some embodiments, when the physical information fusion modeling module 203 constructs a behavior agent model for a general-purpose ground mobility platform, it does not rely on historical fault records or usage frequency statistics. Instead, it models the general-purpose ground mobility platform based solely on its physical structural parameters (such as the heat capacity of the power heat source of 4.18 kJ / (kg*K)), control logic (such as starting the cooling unit when the temperature is >45℃), and real-time collected multi-physics field observation data, according to the control equations derived from first principles (such as the power battery thermal diffusion equation). This supports the performance verification of newly developed general-purpose ground mobility platforms or the first set of general-purpose ground mobility platforms without historical operating data.
[0034] To visually demonstrate the system's effectiveness in verifying platforms without historical data, a specific implementation verification is conducted based on the functions of the aforementioned modules: This embodiment verifies the core performance of a general-purpose ground mobility platform without historical operational data. This platform features a completely new design, and the absence of historical fault data and operational statistics can be used for model training. Traditional verification methods require manual setting of operational conditions based on experience with similar platforms, with parameter iterations and adjustments no less than three times. Only kinematic parameters are collected, and the complete verification cycle takes 25-35 days, providing only a qualitative "pass / fail" conclusion.
[0035] When performing verification using the system of this invention, the specific process is as follows: The test task injection module extracts the heat generation rate of the power heat source (referring to the heat generated by the power heat source per unit time) of 3.2 kW based on the digital prototype of the general ground mobility platform and converts it into a test constraint set; The multi-physics synchronous acquisition module synchronously acquires heat flow data from the power heat source and strain data from the platform frame structure. The physical information fusion modeling module loads the thermal diffusion equation of the power battery. Complete the modeling; The uncertainty quantification assessment module calculated a credibility index (used to measure the degree of conformity between the verification results and the actual situation) of 2.8℃, which is lower than the preset threshold of 3℃. The verification result feedback module triggers test reconfiguration and prioritizes adjusting the power charge / discharge rate parameter range through sensitivity analysis.
[0036] The verification cycle was only 12 days, which is 50%-70% shorter than the traditional solution. It achieved highly reliable quantitative verification of the newly developed general-purpose ground mobility platform and the first set of general-purpose ground mobility platforms without historical data.
[0037] In some embodiments, the governing equations include at least one of the following: the longitudinal dynamics equation of the general-purpose ground mobility platform, the thermal diffusion equation of the power battery, or the electromagnetic field equation of the motor. The type of the governing equation is dynamically loaded according to the test task type to satisfy the corresponding physical constraints. For example, when the verification target is "power heat source management performance of the general-purpose ground mobility platform", the system automatically loads the thermal diffusion equation of the power battery as the governing equation to reflect the physical constraints of the thermal field constituted by the boundary conditions of heat conduction, heat generation, and heat dissipation. When the verification target is "braking performance of the general-purpose ground mobility platform", the system automatically loads the braking dynamics equation of the general-purpose ground mobility platform (including braking force distribution, friction coefficient, and inertial response) as the governing equation to reflect the physical constraints of the mechanical field. When the verification target is "electromagnetic compatibility of the motor of the general-purpose ground mobility platform", the system automatically loads the electromagnetic field equation of the motor (such as the simplified form of the Maxwell equations) to satisfy the physical constraints of the electromagnetic field.
[0038] The digital vehicle testing and verification system of this invention has the following advantages: 1. This invention enables highly reliable verification in scenarios without historical data: the physical information fusion modeling module relies only on the physical structure parameters, control logic, and real-time multiphysics field measured data of the general ground mobility platform. Based on the control equations derived from first principles (such as the battery thermal diffusion equation), it constructs a behavioral proxy model of the general ground mobility platform. It does not require historical fault or usage frequency statistics, providing a feasible verification path for newly developed general ground mobility platforms and the first set of general ground mobility platforms. 2. This invention can quantitatively verify the conclusions to support engineering decisions: The uncertainty quantification assessment module generates a 95% confidence interval width as a credibility index through Monte Carlo Dropout, transforming the fuzzy "pass / fail" judgment into an objective quantitative assessment, which is conducive to improving the reliability of high-risk engineering decisions; 3. This invention enables efficient closed-loop iteration of the verification process: the verification result feedback module automatically triggers sensitivity analysis based on the credibility index, identifies key test parameters and prioritizes adjusting their value range, avoiding blind trial and error and improving verification efficiency; 4. This invention enables precise integration of design and testing: The test task injection module automatically extracts key performance boundary conditions based on a digital prototype of a general ground mobility platform, converts them into a set of test constraints, and generates a set of executable test parameters, accurately covering the design objectives.
