[0002] With the development of intelligent and networked vehicles, modern vehicles have developed from traditional functional applications to intelligent, networked and electric vehicles. Major domestic traditional and new force vehicle manufacturers are developing intelligent driving systems for vehicles, such as adaptive cruise control, automatic emergency braking and lane departure warning. These intelligent driving functions need to be used in various complex environments, such as strong electromagnetic compatibility environments. Therefore, testing the performance of vehicle electromagnetic interference resistance is a necessary work.
[0003] Currently, the existing method is to increase intelligent auxiliary devices for activating the adaptive cruise control function and forward collision warning function of the vehicle in a semi-anechoic chamber. When the test conditions of the vehicle under test are stable, the electromagnetic immunity test of the automatic driving assistance function of the vehicle is carried out according to the test method. The signal of the vehicle under test and the test phenomenon are monitored to classify and evaluate the electromagnetic safety of the intelligent vehicle.
[0004] However, although the existing method can model the overall system of the vehicle system, for the complex electromagnetic compatibility problem in the vehicle system, the existing modeling method has slow simulation speed, which leads to the extension of the development cycle of the vehicle, and cannot fully cover the needs of intelligent driving functions in complex electromagnetic environments, such as simulating pedestrians crossing the road in various directions while the vehicle is running in the whole vehicle electromagnetic compatibility laboratory, triggering the test requirements of automatic emergency braking and automatic continuous driving, i.e. the test requirements of the function after the pedestrian moves away.

[0050] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0051] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0052] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.
[0053] The main solution of this application embodiment is: to acquire simulated test scenario data, which is collected in a semi-anechoic chamber for the whole vehicle by setting up a vehicle electromagnetic compatibility pedestrian test scenario; to verify the electromagnetic compatibility vehicle function based on the simulated test scenario data and determine the verification result; to expand the electromagnetic compatibility vehicle function items based on the verification result and determine the vehicle intelligent driving function test fixture; and to automatically match typical road conditions using the vehicle intelligent driving function test fixture.
[0054] In this embodiment, for ease of description, the following description will focus on the vehicle electromagnetic compatibility pedestrian simulation system verification device.
[0055] While existing technologies can model the overall vehicle system, they are slow to simulate complex electromagnetic compatibility issues within the vehicle system, leading to extended vehicle development cycles. Furthermore, they cannot fully cover the requirements of intelligent driving functions in complex electromagnetic environments. For example, in a vehicle electromagnetic compatibility laboratory, when simulating vehicle operation, pedestrians may cross the road from various directions, triggering automatic emergency braking, and the function of automatically continuing driving after the pedestrians have moved away is also tested.
[0056] This application provides a solution for acquiring simulated test scenario data, which is collected in a semi-anechoic chamber for a vehicle by constructing an electromagnetic compatibility (EMC) pedestrian test scenario; verifying the EMC vehicle function based on the simulated test scenario data to determine the verification result; expanding the EMC vehicle function items based on the verification result to determine the vehicle intelligent driving function test fixture; and automatically matching typical road conditions using the vehicle intelligent driving function test fixture.
[0057] As can be seen from the above embodiments, this application verifies the electromagnetic compatibility function of the vehicle by building a simulated test scenario and collecting data in a semi-anechoic chamber for the whole vehicle, and expands the functional items based on the verification results, thereby determining the test fixture for the intelligent driving function of the whole vehicle, realizing automatic matching of typical road conditions, significantly improving the efficiency and accuracy of performance testing of the intelligent driving system in complex electromagnetic environments, and ensuring the safety and stability of the vehicle.
[0058] Based on this, embodiments of this application provide a verification method for a vehicle electromagnetic compatibility pedestrian simulation system, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the vehicle electromagnetic compatibility pedestrian simulation system verification method of this application.
[0059] In this embodiment, the verification method for the vehicle electromagnetic compatibility pedestrian simulation system includes steps S10 to S30:
[0060] Step S10: Obtain simulated test scenario data. The simulated test scenario data is collected by constructing a vehicle electromagnetic compatibility pedestrian test scenario in a semi-anechoic chamber for the whole vehicle.
[0061] It should be noted that the simulated test scenario data reflects the specific performance parameters actually tested under electromagnetic interference.
[0062] It is understandable that, such as Figure 2 As shown, Figure 2 This document presents a test layout diagram for the vehicle radiated immunity and pedestrian simulation system of the vehicle electromagnetic compatibility (EMC) pedestrian simulation system verification method of this application. The diagram includes a radiated interference transmitting antenna, a rotating strand, a camera, a ranging radar, a pedestrian base, a simulated pedestrian guide rail, a motor, a wall panel connector, and a pedestrian simulation console. The radiated interference transmitting antenna is used to transmit antenna signals to obtain EMC status values during vehicle radiated immunity testing. The rotating strand is used to fix the test vehicle to obtain EMC vehicle status data and also to limit vehicle movement to obtain vehicle movement status data. The camera, ranging radar, pedestrian base, simulated pedestrian guide rail, and motor are used to assemble the simulated pedestrian assembly. The wall panel connector is used to connect the simulated pedestrian assembly to simulate pedestrian movement modes and obtain data from the pedestrian simulation console. The pedestrian simulation console is used to connect to the wall panel connector to control the motor to simulate pedestrian movement modes and obtain device simulation settings information, camera information, and power switch information.
[0063] For ease of understanding, we will take the acquisition of simulated test scenario data as an example, where the information acquisition device is the information acquisition module and the storage device is the memory.
[0064] In a semi-anechoic chamber for the entire vehicle, a vehicle-wide electromagnetic compatibility (EMC) pedestrian test scenario is constructed. This scenario includes a radiated interference transmitting antenna, a rotating track, a camera, a ranging radar, a pedestrian base, a simulated pedestrian rail, a motor, wall panel connectors, and a pedestrian simulation control console. Simulated test scenario data is collected based on this scenario and then processed. The radiated interference transmitting antenna is a standard vehicle-wide EMC test antenna that simulates an electromagnetic interference environment and pedestrian behavior. A movable pedestrian fixture is tested, where a motor drives the rail, thereby moving the simulated pedestrian at constant speed, accelerating, decelerating, or moving away from the test vehicle, simulating triggering events on the vehicle. The system includes an emergency braking function and a cruise control mode activation function. Simultaneously, it can simulate pedestrians with cameras and ranging radars positioned on their head, torso, and legs. It simulates pedestrian speed, distance between pedestrians and vehicles, and vehicle actions such as braking, starting, and light changes. This data is transmitted via fiber optic cable to the pedestrian simulation control and monitoring console, providing control parameters and test result analysis. The pedestrian base securely connects the simulated pedestrian to a pedestrian guide rail. The movement of the guide rail moves the pedestrian. The simulated pedestrian guide rail consists of a track for the pedestrian and the guide rail. The motor can rotate forward and backward, controlling the pedestrian's movement towards or away from the vehicle under test. The wall panel connector can bridge the connection channels between the vehicle's darkroom and the external control room. The pedestrian simulation control console can control and set various movement modes for the motor and the simulated pedestrian.
[0065] Step S20: Verify the electromagnetic compatibility of the vehicle based on the simulated test scenario data and determine the verification results;
[0066] It should be noted that the verification results reflect the performance characteristics of the vehicle electromagnetic compatibility pedestrian simulation system under simulated test scenarios.
[0067] It is understood that the verification results include the verification results of the emergency braking function and the cruise function, which are used to more accurately evaluate the performance of the system in a simulated electromagnetic environment, ensure the reliability of functions such as emergency braking and cruise under electromagnetic interference, and improve the safety of the vehicle in actual use.
[0068] Additionally, it should be noted that intelligent cars equipped with adaptive cruise control systems can use radar and computers to identify bicycles, cars, and pedestrians approaching the vehicle, and control the vehicle's driving status according to road conditions, thereby completely or partially replacing the driver's operation. Furthermore, when testing the cruise function, the simulation test can be achieved by replacing the human form on the guide rail platform with the form of a car.
[0069] For ease of understanding, we will take the determination of verification results as an example, where the information acquisition device is the information acquisition module, the storage device is the memory, and the processing device is the data analysis module.
[0070] In a semi-anechoic chamber for the whole vehicle, an electromagnetic compatibility (EMC) pedestrian test scenario is constructed to obtain simulated test scenario data. Based on the simulated test scenario data, the EMC function of the whole vehicle is verified to determine the verification result, and subsequent processing is carried out based on the verification result.
[0071] In a semi-anechoic chamber within the vehicle, an electromagnetic compatibility (EMC) pedestrian test scenario was constructed to test the system's emergency braking function. The system used radar to measure the distance to the vehicle in front or an obstacle, obtaining simulated test scenario data. This data was then analyzed using a data analysis module, comparing the measured distance, warning distance, and safe distance to verify the emergency braking function. If the measured distance was less than the warning distance, an alarm was triggered. If the measured distance was less than the safe distance, the system would activate automatically, braking the vehicle to ensure safe travel, even if the driver did not have time to apply the brake pedal. The verification results were then obtained, categorized as successful or unsuccessful, and subsequent processing was performed based on these results.
[0072] In a semi-anechoic chamber, a vehicle-wide electromagnetic compatibility (EMC) pedestrian test scenario was constructed to test the system's cruise control function, specifically adaptive cruise control. Based on information detected by the vehicle distance sensor and the vehicle's driving route determined by the vehicle speed and yaw rate sensors, simulated test scenario data was obtained. The vehicle distance sensor employed microwave radar or distance radar to determine whether there were vehicles ahead in the same lane. When there were no vehicles ahead, the system maintained a set speed; when a vehicle appeared ahead, it slowed down to a lower speed to maintain a safe distance from the vehicle ahead, thus verifying the system's cruise control function. Four typical functions were tested, such as the system maintaining normal cruise control when there were no vehicles ahead. In ACC driving mode, the vehicle travels at the speed set by the driver. The driver only needs to control the direction. Alternatively, when a target vehicle appears in front of the ACC vehicle, if the target vehicle's speed is less than that of the ACC vehicle, the ACC vehicle will automatically begin deceleration control to ensure that the distance between the two vehicles is the set safe distance. Or, when the distance between the two vehicles equals the safe distance, the ACC system will follow the target vehicle, i.e., travel at the same speed as the target vehicle. Or, when the target vehicle in front changes lanes, or when the ACC vehicle changes lanes and there are no vehicles in front of the ACC vehicle, the ACC system will accelerate the ACC vehicle to restore it to the set speed, thereby obtaining the verification result. If the verification is successful or unsuccessful, subsequent processing will be carried out based on the verification result.
[0073] In one feasible implementation, step S20 may include steps A11 to A12:
[0074] Step A11: Based on the simulated test scenario data, simulate pedestrian motion conditions to determine pedestrian simulation data. The pedestrian motion conditions include pedestrian uniform motion conditions, pedestrian acceleration motion conditions, and pedestrian deceleration motion conditions.
[0075] It should be noted that the pedestrian simulation data reflects the characteristics of pedestrians' movement state in the simulated environment.
[0076] It is understood that the pedestrian simulation data may include the pedestrian's target speed, target direction, actual position, direction of movement, and interaction with others and obstacles, thereby characterizing the pedestrian's movement behavior in a specific environment, such as obstacle avoidance, path selection, speed changes, and interaction in a group, such as following, avoiding, and forming a queue.
[0077] Step A12: Verify the electromagnetic compatibility vehicle functions based on the pedestrian simulation data to obtain verification results. The electromagnetic compatibility vehicle functions include emergency braking and cruise control.
[0078] It is understandable that the pedestrian simulation data can more accurately predict the location and status of pedestrians, and can help intelligent driving systems respond better to pedestrian behavior under electromagnetic interference, thereby improving the safety and reliability of the system, saving costs and improving development efficiency.
[0079] Step S30: Based on the verification results, expand the electromagnetic compatibility vehicle function items to determine the vehicle intelligent driving function test fixture, and apply the vehicle intelligent driving function test fixture to automatically match typical road conditions.
[0080] It should be noted that the aforementioned vehicle intelligent driving function testing fixture reflects the characteristics of a testing environment adapted to simulated traffic environments and actual road conditions.
[0081] It is understandable that the aforementioned vehicle intelligent driving function testing fixture can simulate various traffic environments and conditions, comprehensively evaluate the performance of the intelligent driving system, and significantly improve the accuracy of test results.
[0082] Additionally, it should be noted that the typical road conditions may include typical road conditions for autonomous driving, typical road conditions for electromagnetic interference, and typical road conditions for functional testing in non-electromagnetic compatibility laboratories. The typical road conditions for autonomous driving are tested when, during autonomous driving, a pedestrian, motor vehicle, or non-motor vehicle runs a red light while the traffic light is green and the vehicle is permitted to drive. The typical road conditions for electromagnetic interference are tested when electromagnetic interference is applied. The typical road conditions for functional testing in non-electromagnetic compatibility laboratories are tested in functional testing scenarios in non-electromagnetic compatibility laboratories, i.e., human-vehicle interaction scenarios or road test scenarios, to assess the functional response.
[0083] For ease of understanding, we will take the test fixture for obtaining the intelligent driving function of the whole vehicle as an example. The information acquisition device is the information acquisition module, the storage device is the memory, and the execution device is the execution module.
[0084] The information acquisition module obtains the verification results. Based on these results, it replaces the vehicle electromagnetic compatibility (EMC) pedestrian test scenario to determine the vehicle model test scenario. The vehicle model test scenario includes vehicle driving test scenarios, following test scenarios, and pre-collision test scenarios. This involves replacing the simulated pedestrian with a vehicle model, simulating the test conditions required for vehicle driving, following, and pre-collision scenarios, and installing systems such as brakes and turn signals on the simulated vehicle to adapt to the vehicle model test scenario. Simultaneously, corresponding settings parameters are replaced in the pedestrian simulation settings interface, and settings are synchronized. Alternatively, vehicle EMC testing is performed. Based on the vehicle model test scenario, the vehicle's anti-interference performance is tested to obtain the vehicle intelligent driving function test fixture. This involves fixing the vehicle to a rotating platform, and the vehicle running at a certain speed on the platform. For the non-displacement state, simulated pedestrians are replaced with traffic lights, such as red, green, yellow, left turn, and right turn lights, to test the anti-interference performance of intelligent driving under traffic recognition conditions. This is adapted to whole vehicle model test scenarios. At the same time, it can also be expanded into whole vehicle intelligent driving function test fixtures for application in non-vehicle electromagnetic compatibility environments, such as typical road scenarios. That is, when the traffic light is green and motor vehicles can drive, if a pedestrian, motor vehicle, or non-motor vehicle runs a red light, the function response status is tested. The typical road conditions for electromagnetic interference test the function response status when electromagnetic interference is applied. The typical road conditions for functional testing in non-electromagnetic compatibility laboratories test the function response status in functional testing scenarios in non-electromagnetic compatibility laboratories, i.e., human-vehicle interaction scenarios or road test scenarios.
[0085] In one feasible implementation, step S30 may include steps B11 to B12:
[0086] Step B11: Based on the verification results, replace the whole vehicle electromagnetic compatibility pedestrian test scenario to determine the whole vehicle model test scenario. The whole vehicle model test scenario includes vehicle driving test scenario, following vehicle test scenario and pre-collision test scenario.
[0087] It should be noted that the vehicle model test scenario reflects the characteristics of the scenario for conducting electromagnetic compatibility testing on intelligent driving vehicles.
[0088] It is understood that the vehicle simulation test scenario can simulate various situations that a vehicle may encounter in actual driving, including driving, following other vehicles, and pre-collision, thereby measuring the response status of the function under electromagnetic interference conditions, more accurately evaluating the performance of the intelligent driving system under electromagnetic interference, and ensuring the safety and functionality of the vehicle in actual use.
[0089] Step B12: Based on the vehicle model test scenario, detect the vehicle's anti-interference performance to obtain the vehicle intelligent driving function test fixture.
[0090] Understandably, the vehicle intelligent driving function testing fixture can test the response status of the function in advance, discover potential safety issues, and thus make improvements before the vehicle is actually put into use, thereby improving vehicle safety. It also allows for multiple tests in a controlled environment, reducing the need for real vehicle testing and lowering costs and time consumption.
[0091] In another feasible implementation, step S30 may include steps C11 to C12:
[0092] Step C11: Based on the vehicle model test scenario, detect traffic recognition conditions and determine the detection results. The traffic recognition conditions include braking recognition conditions and turn signal light recognition conditions.
[0093] It should be noted that the detection results reflect the characteristics of the intelligent driving vehicle's recognition ability in actual traffic environments.
[0094] Understandably, intelligent driving vehicles can efficiently and accurately detect multiple targets in complex traffic scenarios, thereby reducing traffic accidents and improving the safety of intelligent driving systems.
[0095] Step C12: Based on the detection results, package the vehicle intelligent driving function test fixture.
[0096] Understandably, the encapsulated testing fixture for intelligent driving functions of the entire vehicle is a valuable reference, easy to implement and expand, significantly improves reusability, adapts to various environments, ensures that the function remains responsive under electromagnetic interference and other interference conditions, and significantly improves the user experience.
[0097] This embodiment proposes a method for verifying a vehicle electromagnetic compatibility (EMC) pedestrian simulation system. The method involves acquiring simulated test scenario data, which is collected in a semi-anechoic chamber within the vehicle by constructing an EMC pedestrian test scenario. Based on the simulated test scenario data, the EMC functions of the vehicle are verified to determine the verification results. Based on the verification results, the EMC functions of the vehicle are expanded to determine the intelligent driving function test fixture, which is then applied to automatically match typical road conditions. This method solves the technical problem of how to efficiently verify the performance of an intelligent driving system in complex electromagnetic environments. Compared to existing technologies, this application constructs a simulated test scenario in a semi-anechoic chamber within the vehicle and collects data. It utilizes radiated interference transmitting antennas, antennas, cameras, and other equipment to simulate real traffic and electromagnetic environments, accurately collecting simulated test scenario data. Based on this data, the EMC functions of the vehicle are verified and the verification results are determined. Based on the verification results, functional items are expanded, and the intelligent driving function test fixture is determined, enabling it to automatically match typical road conditions. This significantly improves the efficiency and accuracy of performance testing of the intelligent driving system in complex electromagnetic environments, ensuring the safety and stability of the vehicle.
[0098] Based on the first embodiment of this application, in the second embodiment of this application, the same or similar content as the first embodiment can be referred to the above description, and will not be repeated hereafter.
[0099] In this embodiment, refer to Figure 3 , Figure 3 This is a flowchart illustrating Embodiment 2 of the verification method for the vehicle electromagnetic compatibility pedestrian simulation system of this application. Step S10 specifically includes steps S11 to S12:
[0100] Step S11: Obtain electromagnetic compatibility vehicle status data and pedestrian simulation control console data;
[0101] It should be noted that the electromagnetic compatibility vehicle status data reflects the characteristics of the vehicle's working state in the electromagnetic environment, and the pedestrian simulation control console data reflects the characteristics of the simulated pedestrian's motion state and control parameters.
[0102] It is understandable that, such as Figure 4 As shown, Figure 4 This is a schematic diagram of the pedestrian simulation control and monitoring console interface and structure of the vehicle electromagnetic compatibility pedestrian simulation system verification method of this application. It includes device simulation settings, camera video display and power switch functions. The device simulation settings include adding settings, saving settings, deleting settings, importing settings, random settings, starting operation and function reservation. The camera video display includes radar settings, pedestrian distance, camera settings, pedestrian speed, video screenshot button and video save button. The power switch function includes power switch, emergency stop switch and reset switch.
[0103] For ease of understanding, we will take the acquisition of electromagnetic compatibility vehicle status data and pedestrian simulation console data as an example, where the information acquisition device is the information acquisition module and the storage device is the memory.
[0104] In a semi-anechoic chamber for the entire vehicle, an electromagnetic compatibility (EMC) pedestrian test scenario is constructed, including a radiated interference transmitting antenna, a rotating beam, a camera, a ranging radar, a pedestrian base, a simulated pedestrian rail, a motor, a wall panel connector, and a pedestrian simulation console. Based on this EMC pedestrian test scenario, EMC vehicle status data is collected, and data from the pedestrian simulation console is collected under electromagnetic interference conditions. That is, data is collected through the pedestrian simulation console, which includes device simulation settings, camera video display, and power switch functions.
[0105] The system can simulate a pedestrian setting interface, allowing users to set the relative start position, end position, speed, and waiting time of pedestrians, thus determining the device's pedestrian setting information. This device's pedestrian setting includes functions such as adding settings, saving settings, deleting settings, importing settings, random settings, starting operation, and function reservation. Adding and deleting settings allow users to modify current settings parameters. Saving settings saves the current settings after parameter configuration and allows setting a save sequence number. Importing settings imports previously set parameters by retrieving saved sequence numbers. Random settings randomly configure pedestrians based on possible pedestrian actions. After setting and checking all settings, starting operation runs the system, with the motor driving the guide rail to drag the pedestrian base and pedestrian according to predetermined requirements. Function reservation allows users to reserve some unknown or user-specified modes and reserve soft switch settings.
[0106] The camera, radar video, and ranging interface can transmit current pedestrian and vehicle status information back to the control and monitoring console via a simulated pedestrian-installed camera and radar system. This information is used for testing, monitoring, judgment, and equipment self-calibration, and to determine camera information. The camera video display includes radar settings, pedestrian distance, camera settings, pedestrian speed, a video screenshot button, and a video save button. The radar and camera settings allow users to turn the camera on and off, and set the radar and camera angles. When the radar and camera are on, the display interface shows the pedestrian and vehicle distances, pedestrian and vehicle speeds, and real-time video information in real time. The video screenshot button allows users to capture the current video and vehicle speed and distance information with a single click. The video save button saves the test video recording from the start of the test until the save button is pressed.
[0107] Pedestrians can control the power switch via the monitoring station equipment to determine the power switch information. The power switch functions include a power switch, an emergency stop switch, and a reset switch. The power switch controls the on / off state of the equipment's power supply and is the power control switch for starting and stopping the equipment. The emergency stop switch is the equipment's safety control switch, cutting off the equipment's power supply in emergencies, such as when the pedestrian simulator derails or gets stuck, to ensure equipment safety. The reset switch is the equipment restart switch. When the equipment experiences software freezes or abnormal settings interface, pressing the reset switch will restart the equipment and return it to an initial state.
[0108] The pedestrian simulation console data is determined based on the device simulator settings, the camera information, and the power switch information.
[0109] In one feasible implementation, step S11 may include steps D11 to D13:
[0110] Step D11: Obtain electromagnetic interference status value, vehicle motion status data, equipment manipulator setting information, camera information, and power switch information;
[0111] It should be noted that the electromagnetic interference status value reflects the intensity of electromagnetic interference experienced by the vehicle in the electromagnetic environment, the vehicle motion status data reflects the characteristics of the vehicle's motion status during the test, the device simulator setting information reflects the characteristics of various motion modes and behavioral parameters of the simulated pedestrian, the camera information reflects the characteristics of the video stream and image data captured by the camera, and the power switch information reflects the characteristics of the device's power management status.
[0112] Step D12: Determine electromagnetic compatibility vehicle status data based on the electromagnetic interference status value and the vehicle motion status data;
[0113] It is understood that the electromagnetic interference status value can identify sensitive components and functions in the vehicle system that may be affected by electromagnetic interference, and assess the vehicle's ability to resist external electromagnetic interference in actual use. The vehicle motion status data can simulate the driving scenario of the vehicle under real traffic conditions, ensuring the accuracy and reliability of the test results.
[0114] Step D13: Determine pedestrian simulation console data based on the device simulator settings information, the camera information, and the power switch information.
[0115] It is understood that the device simulation settings information can provide more realistic and diverse test scenarios to evaluate the responsiveness and adaptability of the intelligent driving system. The camera information can provide visual information about the vehicle's surrounding environment to help the system identify pedestrians, vehicles, and traffic signs. The power switch information can maintain the safe and stable operation of the device during the test and prevent device damage or test data loss in abnormal situations.
[0116] In one feasible implementation, steps E11 to E14 may be included before step D13:
[0117] Step E11: Obtain new setting information, save setting information, delete setting information, import setting information, random setting information, start running information, function reserved information, radar setting information, camera setting information, pedestrian distance information, pedestrian speed information, video button information, power switch information, emergency stop switch information, and reset switch information;
[0118] It should be noted that the "Add Settings" information reflects the feature that users can add new parameter settings according to testing needs; the "Save Settings" information reflects the feature that the current setting parameters are saved; the "Delete Settings" information reflects the feature that users can delete settings that are no longer needed; the "Import Settings" information reflects the feature that users can import previously saved settings; the "Random Settings" information reflects the feature that setting parameters can be randomly generated; the "Start Running" information reflects the feature that all settings will be activated and used for actual testing; the "Function Reserved" information reflects the feature that setting space is reserved for newly added functions; the "Radar Settings" information reflects the feature that the vehicle's perception accuracy of the surrounding environment is accurate; the "Camera Settings" information reflects the feature that the quality and detail of the images captured by the camera are high; the "Pedestrian Distance" information reflects the feature that pedestrian positions are accurately measured; the "Pedestrian Speed" information reflects the feature that pedestrian dynamic behavior is monitored; the "Video Button" information reflects the feature that users can operate through the video interface; the "Power Switch" information reflects the feature that the device's operating status is controlled; the "Emergency Stop Switch" information reflects the feature that the power can be quickly cut off when danger is detected; and the "Reset Switch" information reflects the feature that the device is reset when the system malfunctions.
[0119] Step E12: Determine the device model setting information based on the newly added setting information, the saved setting information, the deleted setting information, the imported setting information, the random setting information, the start running information, and the function reserved information;
[0120] Understandably, the newly added settings information allows users to add new parameter settings according to test requirements; the saved settings information allows users to retain current settings parameters; the deleted settings information allows users to remove settings that are no longer needed; the imported settings information allows users to quickly restore previous settings; the random settings information can randomly generate settings parameters to simulate unpredictable pedestrian behavior; the start-up information indicates that all settings will be activated and used for actual testing; and the function reservation information allows for the expansion of existing functions, thereby improving the adaptability and flexibility of testing, enabling the system to quickly respond to different test scenarios and requirements. Furthermore, by simulating real pedestrian behavior through random settings and start-up information, the realism of the test is enhanced, and the performance and safety of the intelligent driving system in complex electromagnetic environments are significantly improved.
[0121] Step E13: Determine camera information based on the radar setting information, the camera setting information, the pedestrian distance information, the pedestrian speed information, and the video button information;
[0122] It is understood that the radar setting information can detect the position parameters of pedestrians or other obstacles in the simulated test, the camera setting information can identify the state parameters of different environments, the pedestrian distance information can accurately identify the actual distance between pedestrians and vehicles, thereby taking corresponding safety measures, the pedestrian speed information can monitor pedestrian dynamic behavior and respond accordingly, and the video button information can monitor and intervene in the test process in real time, thereby improving the flexibility and controllability of the test.
[0123] Step E14: Determine the power switch information based on the power switch information, the emergency stop switch information, and the reset switch information.
[0124] It is understood that the power switch information can characterize the switching status of the device control, ensuring that the device can start and stop normally. The emergency stop switch information can indicate that the power can be quickly cut off in an emergency to protect the safety of the equipment and personnel. The reset switch information indicates that the system can be reset to the initial state when the device malfunctions, ensuring the continuity of testing and the accuracy of data.
[0125] Step S12: Determine the simulation test scenario data based on the electromagnetic compatibility vehicle status data and the pedestrian simulation console data.
[0126] It is understood that the electromagnetic compatibility vehicle status data can characterize the specific functional test status of the system when the vehicle is undergoing electromagnetic compatibility testing, and the pedestrian simulation console data can characterize the status of pedestrians in the test environment. That is, the speed of pedestrians, the distance between them and the vehicle, and the actions of the vehicle can be transmitted back to the control and monitoring console through the installed camera and radar system, so as to analyze the test results and determine the simulated test scenario data.
[0127] For ease of understanding, we will take the determination of simulated test scenario data as an example, where the information acquisition device is the information acquisition module and the storage device is the memory.
[0128] In a semi-anechoic chamber for the whole vehicle, an electromagnetic compatibility (EMC) pedestrian test scenario is constructed, including a radiated interference transmitting antenna, a rotating beam, a camera, a ranging radar, a pedestrian base, a simulated pedestrian guide rail, a motor, a wall panel connector, and a pedestrian simulation control console. Simulated test scenario data is collected based on the whole vehicle EMC pedestrian test scenario, and subsequent processing is performed based on the simulated test scenario data.
[0129] This embodiment proposes a verification method for a vehicle electromagnetic compatibility (EMC) pedestrian simulation system. It acquires EMC vehicle status data and pedestrian simulation console data; and determines simulation test scenario data based on the EMC vehicle status data and the pedestrian simulation console data. This solves the technical problem of how to accurately conduct simulation tests in complex electromagnetic environments by setting up simulation test scenarios. Compared to existing technologies, this application constructs a simulation test scenario in a semi-anechoic chamber within the vehicle, utilizing a radiated interference transmitting antenna, a rotating antenna, a camera, and a ranging radar to accurately collect EMC vehicle status data and pedestrian simulation console data, thereby determining the simulation test scenario data. From the perspective of circuit principles and design logic, it is simple and convenient to implement, and the equipment packaging method is referable. It organically combines vehicle testing and intelligent driving functions, and the functionality of the test bench can be expanded according to the intelligent driving functions. The system has strong reusability and significantly improves the safety and reliability of intelligent driving systems in practical applications, reduces the need for real-vehicle testing, lowers costs and time consumption, and improves testing efficiency and accuracy.
