[0010] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application. Attached Figure Description

In the drawings: Figure 1 A flowchart illustrating a test and evaluation method for a forward proximity safety warning system for commercial vehicles provided in an embodiment of this application is shown. Figure 2 This illustration shows a schematic diagram of a first test range located directly in front of a commercial vehicle, according to an embodiment of this application.

Figure 4 This paper shows a schematic diagram of the structure of a test and evaluation device for a forward proximity safety warning system for commercial vehicles provided in an embodiment of this application. Detailed Implementation

[0012] To facilitate the explanation of the embodiments of this application, some technical terms and technical means related to the embodiments of this application, as well as the application scenarios of the embodiments of this application, will be introduced first below.

[0013] In one implementation, since commercial vehicles have the disadvantages of large body size and obvious blind spots in front, a forward proximity safety warning system can be installed on the commercial vehicle. Through this forward proximity safety warning system, obstacle information in the near distance area in front of the vehicle can be monitored in real time, and a warning can be issued to the driver in time when there is a risk of collision. This can make up for the disadvantages of large body size and obvious blind spots in front of commercial vehicles, improve the safety and reliability of commercial vehicle driving and operation, and reduce traffic accidents and property damage.

[0014] In some cases, to ensure that the forward proximity safety warning system can promptly detect obstacles in front of a commercial vehicle, an indirect vision device can be installed in front of the vehicle. This device provides a good indirect view within 2 meters (m) in front of the commercial vehicle, thereby improving forward visibility safety. For example, the indirect vision device can be a Class VI forward-facing mirror. Alternatively, a camera installed in the commercial vehicle can capture video footage of the area in front of the vehicle and display it in real-time on a screen installed inside the vehicle, allowing the driver to monitor road conditions and improving forward visibility safety. Another option is to use an ultrasonic radar installed in front of the commercial vehicle to detect obstacles. Specifically, when the ultrasonic radar detects an obstacle in front of the commercial vehicle, it can output a warning message to promptly remind the driver to avoid it, thus improving driving safety.

[0015] It should be noted that while installing indirect vision devices, cameras, or ultrasonic radar on commercial vehicles can directly or indirectly improve close-range safety when obstacles are detected in front of the vehicle, these methods are easily affected by factors such as the obstacle's location and size. This can lead to lower detection accuracy and delayed response, negatively impacting the driver's experience.

[0016] Therefore, to reduce issues such as low detection accuracy and delayed response, and to improve the driver's driving experience, this application provides a testing and evaluation method for a forward proximity safety warning system for commercial vehicles, applied to forward proximity safety testing scenarios for commercial vehicles. In this method, a target test area is acquired. This target test area includes multiple test points, with a preset distance between adjacent test points. Then, for each test point within the target test area, with a test object placed at the test point, the system controls the commercial vehicle to move forward in response to the vehicle's start-up operation. Subsequently, when the forward proximity safety warning system detects the test object, it outputs a warning message and records the system output parameters. Finally, based on the system output parameters, the performance of the forward proximity safety warning system is verified.

[0017] In this embodiment, by placing test objects within a target test area including multiple test points and controlling commercial vehicles to proceed sequentially for testing, multi-point, standardized, and systematic testing of the forward proximity safety warning system can be achieved. This accurately records system output parameters and verifies system performance, effectively improving the consistency, accuracy, and repeatability of the test. It ensures that the forward proximity safety warning system can work reliably in different test locations, improving test efficiency and the credibility of test results, thereby providing a foundation for timely output of warning information.

[0018] The present application will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0019] This embodiment provides a test and evaluation method for a forward proximity safety warning system for commercial vehicles, such as... Figure 1 As shown, the method includes: S101, Obtain the target test area.

[0020] The target test area includes multiple test points, with a preset distance between adjacent test points. This preset distance can be set according to actual conditions. In some embodiments of this application, the preset distance can be 0.1m. In other embodiments, the preset distance can also be 0.2m, 0.15m, etc., and there is no specific limitation.

[0021] In some situations, considering that obstacles do not only appear directly in front of the vehicle during actual driving, but also in the area to the side and front of the vehicle when turning, changing lanes, driving to the side of the road, passing through intersections or narrow sections of road, the target test area mentioned above may include a first test area and a second test area to ensure the comprehensiveness and effectiveness of the system test. The first test area is the test area located directly in front of the commercial vehicle. The second test area is the test area located to the side and front of the commercial vehicle, which may include a left test area and / or a right test area. The left test area is the test area located to the left front of the commercial vehicle. The right test area is the test area located to the right front of the commercial vehicle.

[0022] Specifically, the test length of the first test area is a preset distance interval located directly in front of the commercial vehicle. This preset distance interval may include a first preset distance and a second preset distance, where the first preset distance is less than the second preset distance. The preset distance interval can be pre-set based on the blind zone of the ultrasonic radar. In some embodiments of this application, the preset distance interval can be 0.2~1.0m, that is, the first preset distance is 0.2m and the second preset distance is 1.0m. In other embodiments, the preset distance interval can also be 0.3~1.2m, 0.2~1.2m, etc., and is not specifically limited.

[0023] Optionally, considering that for test areas located far in front of the commercial vehicle, the ultrasonic radar may not be able to accurately detect the test objects placed at the test points within that area, the first test area can be divided into a long-range test area and a short-range test area to facilitate subsequent regional detection of test objects and improve the accuracy of performance verification. The long-range and short-range test areas can be determined based on the detection range of the ultrasonic radar. For example, the long-range test area can be 0.6~1.0m, and the short-range test area can be 0.2~0.6m.

[0024] Furthermore, the test width of the aforementioned first test area can be determined based on the vehicle body width of the commercial vehicle. For example, the test width of the first test area can be the vehicle body width of the commercial vehicle. Alternatively, the test width of the first test area can be the vehicle body width of the commercial vehicle, rounded up to a preset point. This preset point can be one decimal place or an integer, etc., without specific limitations. That is, if the vehicle body width of the commercial vehicle is 1.95m, then the test width of the first test area can be 2.0m. Another example is that the test width of the first test area can also be the sum of the vehicle body width of the commercial vehicle and a preset width. The preset width can be pre-set according to actual conditions, and can be 0.1m, 0.2m, etc.

[0025] For example, such as Figure 2 As shown, taking a commercial vehicle with a body width of 1.95m as an example, the test width of the first test area can be 2.0m, and the test length of the first test area can be located 0.2~1.0m directly in front of the commercial vehicle. The long-distance test area A2 included in the first test area can be located 0.6~1.0m directly in front of the commercial vehicle, and the short-distance test area A1 included in the first test area can be located 0.2~0.6m directly in front of the commercial vehicle. It can be seen that the first test area includes multiple test points, and the distance between adjacent test points is 0.1m.

[0026] Specifically, the aforementioned second test area is set based on a target axis of symmetry, which is the axis of symmetry formed after the vehicle's travel direction is offset by a preset angle along a preset offset direction. The preset angle can be pre-set according to actual conditions. For example, the preset angle can be 45 degrees (°). For instance, taking the left test area included in the second test area as an example, the target axis of symmetry can be the axis of symmetry formed after the vehicle's travel direction is offset 45° to the left. Similarly, taking the right test area included in the second test area as an example, the target axis of symmetry can be the axis of symmetry formed after the vehicle's travel direction is offset 45° to the right.

[0027] Accordingly, the test length of the second test area is a preset distance interval located on the target's axis of symmetry. This preset distance interval can be pre-set based on the detection blind zone of the ultrasonic radar. In some embodiments of this application, the preset distance interval can be 0.25~0.55m. In other embodiments, the preset distance interval can also be 0.3~0.6m, 0.2~0.6m, etc., and is not specifically limited.

[0028] For example, such as Figure 3As shown, taking the right test area included in the second test area as an example, the test length of the first test area can be located at 0.25~0.55m on the target axis of symmetry, which can be the axis of symmetry formed after the vehicle's driving direction is offset to the right by 45°. The test width of the first test area is 0.3m. It can be seen that the second test area includes 4×4=16 test points, and the distance between adjacent test points is 0.1m.

[0029] S102, for each test point included in the target test area, when a test object is placed at the test point, in response to the start operation of the commercial vehicle, controls the commercial vehicle to perform a forward operation.

[0030] Specifically, after obtaining the target test area, the test object can be placed at various test points within the target test area to facilitate multi-point, standardized, and systematic testing of the forward proximity safety warning system, providing a foundation for subsequent accurate verification of system performance. The height of the test object falls within either a first height range or a second height range. The first height range is higher than the second height range. For example, the first height range can be 0.98~1.02m, and the second height range can be 0.48~0.52m. The test object can be an upright rigid cylinder with a diameter of 75 mm, and the material can be metal, wood, or hard plastic, etc.

[0031] Furthermore, after the test object is placed at the test point, the system responds to the commercial vehicle's start-up operation by controlling the vehicle to move forward. It can be understood that during the commercial vehicle's forward movement, the forward proximity safety warning system needs to continuously detect whether a test object appears in front of the vehicle, so as to output a warning message when the test object is detected.

[0032] In some cases, before starting a commercial vehicle, it is necessary to ensure that the vehicle is powered off, meaning all systems within the vehicle are shut down. The vehicle's parking time is then recorded. Only when the parking time reaches a preset duration and a test object is placed at the test point will the vehicle respond to the start-up operation and move forward. The preset parking time can be set according to actual conditions, and can be as short as 30 minutes. This reduces the possibility of interference with system performance due to incomplete system reset, residual power-on states, or insufficient warm-up, ensuring a stable test environment and consistent test conditions. This improves the accuracy, reliability, and repeatability of the test results, objectively and accurately reflecting the actual performance of the forward proximity safety warning system under normal operating conditions such as cold starts.

[0033] Correspondingly, in response to the commercial vehicle's start-up operation, the vehicle can first be placed in neutral, and a first timer can be started. Only if the time recorded by the first timer exceeds a preset waiting period will the vehicle be controlled to move forward. The preset waiting period can be pre-set according to actual conditions, and can be as long as 6 seconds. This ensures that the engine, electrical system, and sensors complete stable power-on and initialization after the commercial vehicle starts, reducing the possibility of the system's performance being affected by unstable operating conditions immediately after startup. It also ensures uniform testing conditions and stable status, effectively improving the accuracy, consistency, and reliability of the test results.

[0034] It should be noted that the testing of the forward proximity safety warning system must be conducted indoors on a flat, dry asphalt or concrete floor, unaffected by environmental interference factors such as wind speed and rain, and unaffected by non-target reflections of sound or electromagnetic waves from walls, auxiliary testing equipment, and other objects in the environment. Furthermore, the test temperature and humidity must be within preset ranges. Both preset temperature and humidity ranges can be pre-set according to actual conditions. For example, the preset temperature range can be 15–25 degrees Celsius (°C), and the preset humidity range can be 35–85%.

[0035] Furthermore, after controlling the aforementioned commercial vehicle to move forward, a second timer can be activated. This second timer is used to record the system response time.

[0036] S103: When the forward proximity safety warning system detects a test object, it outputs a warning message and records the system output parameters.

[0037] Specifically, after the forward proximity safety warning system detects a test object, it can output a warning message to facilitate the determination of the system's response time. This output message can include at least one of the following: playing an alarm sound, providing a voice warning, or displaying a warning message on a screen. The alarm sound can be a continuous tone or a pause shorter than a preset stop time. For example, the warning message could be, "Dear driver, there is a pedestrian crossing 0.5m ahead of the vehicle. Please proceed with caution."

[0038] Correspondingly, while outputting prompts, the system output parameters can also be recorded. These parameters may include the system response time and / or the duration of the prompt message output. The system response time is the duration from when the commercial vehicle begins moving forward until the prompt message is output.

[0039] In some cases, considering the accuracy of system testing, the system response time is only recorded when the height of the test object is within a first height range and the test point is the closest test point to the front of the commercial vehicle within the target test area. In some embodiments of this application, the test point can be the middle test point within a first preset distance range. In other embodiments, the test point can be any test point within the first preset distance, without specific limitations. This eliminates interference factors such as low-lying objects, distant test points, and environmental reflections, ensuring that the measured response time is the core performance parameter of the forward proximity safety warning system under the most sensitive and realistic warning conditions. This effectively improves the relevance, accuracy, and effectiveness of the test data, guaranteeing the reliability of the system response performance verification results.

[0040] S104. Verify the performance of the forward proximity safety warning system based on the system output parameters.

[0041] Specifically, after the system output parameters are recorded, the performance of the forward proximity safety warning system can be verified based on these parameters. This effectively improves the consistency, accuracy, and repeatability of the test, ensuring the forward proximity safety warning system operates reliably in different test locations, enhancing test efficiency and the credibility of the results, thus providing a foundation for timely output of warning information.

[0042] In one implementation, when the system output parameters include system response time, the timeliness of the forward proximity safety warning system can be verified based on the system response time. Specifically, if the system response time is less than a preset response time, the forward proximity safety warning system is deemed to have met the timeliness requirements. If the system response time is greater than or equal to the preset response time, the forward proximity safety warning system is deemed to have failed the timeliness requirements. The preset response time can be pre-set according to actual needs. For example, the preset response time can be 2 seconds. This allows for a quantitative, objective, and unified evaluation of system response performance, reducing errors and uncertainties caused by human judgment, effectively improving the standardization, accuracy, and reliability of test results, and providing a clear and reliable basis for verifying the performance of the forward proximity safety warning system.

[0043] In another implementation, when the output parameter of the above system includes the output duration of the prompt message, the detection accuracy of the front close-range safety prompt system can be verified according to the output duration of the prompt message. Specifically, when the output duration of the prompt message is greater than the preset output duration, it is determined that the detection accuracy of the front close-range safety prompt system is qualified. When the output duration of the prompt message is less than or equal to the preset output duration, it is determined that the detection accuracy of the front close-range safety prompt system is unqualified. Among them, the preset output duration can be set in advance according to actual needs. For example, the preset output duration can be 5s. In this way, a quantitative evaluation of the detection accuracy of the front close-range safety prompt system can be achieved, ensuring that the test judgment criteria are unified and objective, reducing the occurrence of system misdetection and false detection, improving the reliability, standardization and repeatability of the test results, and providing an intuitive and accurate judgment basis for system performance verification.

[0044] Furthermore, in response to the completion of the detection of the test object placed at the test point in the target test area, the number of successful detections of the front close-range safety prompt system can be determined. The number of successful detections refers to the number of times the front close-range safety prompt system successfully detects the test object. Then, according to the number of successful detections and the total number of detections of the front close-range safety prompt system, the area detection performance of the front close-range safety prompt system is verified. The total number of detections of the front close-range safety prompt system is the same as the total number of test points in the target test area. In this way, the detection coverage rate and recognition reliability of the front close-range safety prompt system in the entire test area can be comprehensively, objectively and quantitatively reflected, reducing the one-sidedness brought by single-point or local testing, effectively improving the accuracy, integrity and persuasiveness of the test results, and providing a scientific and reliable basis for the evaluation of the system's area detection ability.

[0045] In some embodiments, when the above target test area includes the first test area, if the ratio between the number of successful detections and the total number of detections of the front close-range safety prompt system is greater than or equal to the preset detection ratio, it is determined that the front area detection performance of the front close-range safety prompt system is qualified. The preset detection ratio can be set in advance according to actual needs. For example, the preset detection ratio can be 89%. If the ratio between the number of successful detections and the total number of detections of the front close-range safety prompt system is less than the preset detection ratio, it is determined that the front area detection performance of the front close-range safety prompt system is unqualified. In this way, a quantitative, unified and objective evaluation of the area detection ability of the front close-range safety prompt system can be achieved, ensuring that the test judgment criteria are standardized and the results are reliable, effectively improving the accuracy, repeatability and authority of the test, and providing a clear and intuitive judgment basis for the verification of the front area detection performance of the system.

[0046] In some cases, when the above-mentioned first test area includes a long-distance test area and a short-distance test area, if the ratio between the number of successful detections in the long-distance test area and the total number of first detections is greater than or equal to the first preset detection ratio, and the ratio between the number of successful detections in the short-distance test area and the total number of second detections is greater than or equal to the second preset detection ratio, it is determined that the detection of the area directly in front of the front short-distance safety prompt system is qualified. If the ratio between the number of successful detections in the long-distance test area and the total number of first detections is less than the first preset detection ratio, and / or the ratio between the number of successful detections in the short-distance test area and the total number of second detections is less than the second preset detection ratio, it is determined that the detection of the area directly in front of the front short-distance safety prompt system is unqualified.

[0047] Among them, the above-mentioned total number of first detections is the same as the total number of test points in the long-distance test area. The above-mentioned total number of second detections is the same as the total number of test points in the short-distance test area. The first preset detection ratio and the second preset detection ratio can be preset according to actual needs. For example, the first preset detection ratio can be 87%, and the second preset detection ratio can be 90%.

[0048] In some other embodiments, when the above-mentioned target test area includes the second test area, considering that the number of test points in the second test area is small. Therefore, in order to ensure the accuracy of the side-front area detection verification, only when the number of successful detections is the same as the total number of detections of the front short-distance safety prompt system, it is determined that the detection of the side-front area of the front short-distance safety prompt system is qualified. When the number of successful detections is different from the total number of detections of the front short-distance safety prompt system, it is determined that the detection of the side-front area of the front short-distance safety prompt system is unqualified. In this way, the full-scale detection ability of the front short-distance safety prompt system for obstacles in the side-front area can be verified strictly and accurately, ensuring that there are no omissions and no missed detections in the key side-front area, effectively improving the severity, reliability and safety of the side-front test, and providing a clear, unified and unambiguous judgment basis for the qualified determination of the system's side-front detection performance.

[0049] Furthermore, in response to the completion of the detection of the test object placed at the test points in the first test area, the undetected area in the first test area can also be determined. Then, based on this undetected area, the area coverage of the front short-distance safety prompt system is verified. In this way, it can directly reflect whether there is a detection blind area in the system, ensuring that the test of the front short-distance safety prompt system is more comprehensive, rigorous and reliable.

[0050] Specifically, if the undetected area includes fewer than or equal to a preset number of test points, the area coverage of the forward proximity safety warning system is deemed satisfactory. If the undetected area includes more than the preset number of test points, the area coverage of the forward proximity safety warning system is deemed unsatisfactory. The preset number can be pre-set according to actual needs. For example, the preset number can be four.

[0051] Furthermore, as Figure 1 In terms of specific implementation, this application provides a test and evaluation device for a commercial vehicle forward proximity safety warning system, such as... Figure 4 As shown, the device includes: an area acquisition module 401, a vehicle control module 402, an information output module 403, and a performance verification module 404.

[0052] The region acquisition module 401 is used to acquire the target test region; wherein, the target test region includes multiple test points, and there is a preset distance between adjacent test points; The vehicle control module 402 is used to control the commercial vehicle to perform forward operation in response to the start operation of the commercial vehicle, when a test object is placed at each test point included in the target test area. The information output module 403 is used to output a warning message and record system output parameters when the forward proximity safety warning system detects a test object. The performance verification module 404 is used to verify the performance of the forward proximity safety warning system based on the system output parameters.

[0053] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the performance verification module 404 is also used to verify the timeliness of the forward proximity safety warning system based on the system response time.

[0054] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the performance verification module 404 is also used to verify the detection accuracy of the forward proximity safety warning system based on the output duration of the warning information.

[0055] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the performance verification module 404 is also used to determine the number of successful detections of the forward proximity safety warning system in response to the completion of the detection of the test object placed at the test point within the target test area; The area detection capability of the forward proximity safety warning system is verified based on the number of successful detections and the total number of detections by the forward proximity safety warning system; wherein the total number of detections by the forward proximity safety warning system is the same as the total number of test points within the target test area.

[0056] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the performance verification module 404 is also used to determine that the detection performance of the front area of ​​the front proximity safety warning system is qualified if the ratio between the number of successful detections and the total number of detections of the front proximity safety warning system is greater than or equal to a preset detection ratio. If the ratio between the number of successful detections and the total number of detections by the forward proximity safety warning system is less than a preset detection ratio, the forward proximity safety warning system is deemed to have failed the detection requirement for the area directly in front of it.

[0057] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the performance verification module 404 is also used to determine that the detection performance of the frontal area of ​​the forward proximity safety warning system is qualified when the number of successful detections is the same as the total number of detections of the forward proximity safety warning system. If the number of successful detections is different from the total number of detections of the forward proximity safety warning system, the detection performance of the forward proximity safety warning system in the side-front area is determined to be unqualified.

[0058] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the vehicle control module 402 is also used to record the parking duration of the commercial vehicle when the commercial vehicle is in a power-off state; When the commercial vehicle has been parked for a preset duration and a test object is placed at the test point, the system responds to the commercial vehicle's start operation by controlling the commercial vehicle to move forward.

[0059] Furthermore, in one possible implementation of this embodiment, such as Figure 4 As shown, the vehicle control module 402 is also used to control the commercial vehicle to be in neutral and start the first timer in response to the starting operation of the commercial vehicle; If the time recorded by the first timer is longer than the preset waiting time, the commercial vehicle is controlled to move forward.
