[0038] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0039] The following describes the evaluation method and device of the vehicle parking system of the embodiment of the present application with reference to the accompanying drawings. In view of the above-mentioned related technologies mentioned in the background technology center, due to the fact that there are still some deficiencies in the function and performance constraints and evaluation of automatic parking, it is easy to cause the environment to be unable to be correctly identified, there is a potential risk of collision, and it may cause the parking process to take a long time, reducing the parking efficiency. The present application provides an evaluation method for a vehicle parking system, in which a parking scene library of a vehicle to be tested can be generated based on multiple parking space elements, and based on each parking scene in the parking scene library, the parking system of the vehicle to be tested is evaluated using multiple evaluation indicators to obtain evaluation data, thereby generating an evaluation result of the parking system of the vehicle to be tested based on the evaluation data, which helps to ensure the comprehensiveness and diversity of the test scene, improve the reliability and accuracy of the test results, and effectively evaluate the performance of the automatic parking system. As a result, the problems in the related technologies that there are still some deficiencies in the function and performance constraints and evaluation of automatic parking, which are easy to cause the environment to be unable to be correctly identified, there is a potential risk of collision, and it may cause the parking process to take a long time, reducing the parking efficiency, etc. are solved.

[0040] Specifically, Figure 1 A schematic flow chart of a method for evaluating a vehicle parking system provided in an embodiment of the present application.

[0041] like Figure 1 As shown, the evaluation method of the vehicle parking system includes the following steps:

[0042] In step S101, a parking scene library of the vehicle to be tested is generated based on a plurality of parking space elements.

[0043] It can be understood that parking space elements refer to basic elements that constitute a parking scene, including but not limited to parking scene type, ground material, parking space type and parking space line type, which can be specifically shown in Table 1, which is a parking space element table.

[0044] Table 1

[0045]

[0046] Specifically, the embodiments of the present application can construct multiple parking space elements of a parking scene, such as parking scene type, ground material, parking space type, and parking space line type, so as to use these parking space elements to construct a specific parking scene, for example, Figure 2 For vertical parking spaces, the depth, width, and position of adjacent vehicles of the parking space should be considered. Figure 3The horizontal space parking spaces shown are all common parking spaces in daily scenes. It is necessary to consider the length, width, distance between the front and rear vehicles, etc. of the parking space. Different parking scenes can be constructed by setting parking spaces of different sizes, different types of vehicles as obstacles, different road widths, and different line of sight obstructions.

[0047] The embodiment of the present application can construct a parking scenario library for the vehicle to be tested based on multiple parking space elements, which can provide a comprehensive and realistic testing environment for subsequent testing processes, and help improve the standardization and specification of the test, and improve the consistency and repeatability of the test.

[0048] Optionally, in one embodiment of the present application, the plurality of parking space elements include multiple items of parking scene type, ground material, parking space type and parking space line type.

[0049] It can be understood that parking scene types include but are not limited to open-air parking lots and underground garages; ground materials include but are not limited to cement, floor paint, grass and floor tiles; parking space types include line parking spaces and space parking spaces, among which line parking spaces include horizontal, vertical and diagonal rows, and space parking spaces include horizontal, vertical and diagonal rows; parking space line types include dotted lines and solid lines, among which solid lines include fully enclosed parking space lines, semi-enclosed parking space lines, unenclosed parking space lines and corner parking space lines.

[0050] The embodiment of the present application utilizes multiple parking space elements to consider the impact of different factors, which helps to improve the comprehensiveness of the test, effectively improve the system's recognition capabilities in complex or poorly marked environments, enhance the robustness of the system, and clear scenario definitions and classifications help to quickly locate problems and improve evaluation efficiency.

[0051] Optionally, in one embodiment of the present application, generating a parking scene library of the vehicle to be tested based on multiple parking space elements includes: combining multiple parking space elements to generate multiple parking scenes; and obtaining a parking scene library based on the multiple parking scenes.

[0052] In the actual implementation process, the embodiment of the present application can first arrange and combine the various elements in Table 1, let the parking system try to identify multiple parking spaces, and record the types of parking space elements that it can identify; then, for common parking spaces, record the accuracy of the parking system in identifying different parking spaces and other parameters to examine its accuracy in identifying parking spaces. Among them, the embodiment of the present application can select the cement floor of an open-air parking lot and the vertical fully enclosed parking space line parking spaces as an illustration.

[0053] The embodiment of the present application can organize and classify the main elements related to the parking space to describe the parking space, thereby forming a systematic and complete parking scene library through permutations and combinations, which is conducive to improving the accuracy of recognition.

[0054] In step S102, based on each parking scenario in the parking scenario library, the parking system of the vehicle to be tested is evaluated using multiple evaluation indicators to obtain evaluation data.

[0055] Specifically, the embodiment of the present application can evaluate the parking system capabilities of the product one by one according to the evaluation indicators according to the evaluation indicators in the product evaluation according to the evaluation indicators. The specific steps can be as follows:

[0056] 1. After entering the parking area, control the vehicle to travel at a speed lower than 10 km / h, and turn on the automatic parking function in the HMI interface of the central control screen;

[0057] 2. After the parking function is turned on, the vehicle speed is controlled to start from 10km / h, with a step length of 1km / h. The vehicle drives and identifies parking spaces at different speeds until the speed exceeds the threshold and the parking space identification is exited. The speed threshold at this time is recorded as the maximum speed during parking space identification;

[0058] 3. Maintain the vehicle speed at 10 km / h, re-enter the parking space recognition, and control the vehicle to continuously pass through 100 sample type parking spaces. Record the number of parking spaces recognized by the system during this process, as well as the number of parking spaces missed and misidentified, and calculate the parking space recognition rate;

[0059] Furthermore, the parking process is evaluated and a vertical fully enclosed parking space is selected as a test parking space, which must have sufficient parking space.

[0060] 1. Turn on the parking system. After the system recognizes the designated parking space, select the parking space and follow the system's prompts. The system then starts to control the vehicle to park automatically without intervening in the vehicle until the system prompts that parking is complete or prompts the user to take over.

[0061] 2. Use a timer to record the time from clicking the parking button to the end of parking as the parking time, and record the number of times the parking space is rubbed, the parking speed and other data during the parking process;

[0062] 3. Record the system's lateral and longitudinal control of the vehicle during parking, such as the steering wheel's rotation amplitude and speed, and whether the braking is abrupt, and give a subjective evaluation and score for the smoothness and comfort of the parking process; record the HMI prompts during parking: whether there is scene reconstruction, whether the depiction of surrounding real-time obstacles is comprehensive and accurate, such as whether pedestrians and pillars are misidentified, whether the voice recognition is timely and accurate during parking, etc.

[0063] 4. After parking, use the length and angle measuring tools to Figure 3 Measure the angles between the front and rear wheels and the parking space lines on both sides, and between the vehicle body and the direction of the parking space, to assess whether the position after parking is completed is centered in the parking space.

[0064] Therefore, the embodiment of the present application can repeat the above process 100 times, record the performance of each parking process and record the score according to Table 2, where Table 2 is an evaluation index and score table of the parking system capability.

[0065] Table 2

[0066]

[0067] The embodiment of the present application utilizes multiple evaluation indicators to evaluate the parking system of the vehicle under test, which is beneficial to improving the accuracy and reliability of the test. Based on each parking scenario in the parking scenario library, the accuracy and reliability of the test can be improved, and it is helpful to generate a high-quality and high-reliability parking system and enhance the intelligence level of the system.

[0068] Optionally, in one embodiment of the present application, the multiple evaluation indicators include at least two of the parking success rate, parking space recognition rate, parking speed, average parking time, maximum parking speed for parking space recognition, average number of parking rubbing times, posture after parking completion, smoothness of the parking process, comfort of the parking process, whether the HMI has scene reconstruction, whether the HMI scene reconstruction is accurate and real-time, whether the HMI has voice prompts, and whether the HMI voice prompts are smooth and real-time.

[0069] It is understandable that the parking success rate and parking space recognition rate are the most important indicators for evaluating the capabilities of a parking system. By repeating the parking process many times, statistically significant data can be obtained. The number of parking maneuvers refers to the number of times the gear is switched between D and R during the parking process, reflecting the system's ability to plan parking trajectories. The posture after parking is completed refers to the position and posture of the vehicle relative to the parking space, mainly the distance from the parking space boundary, and the relative angle, etc.

[0070] The embodiments of the present application help to comprehensively evaluate the system's ability to plan parking trajectories and control the vehicle to accurately drive according to the calculated parking trajectory from objective aspects such as parking power and time, as well as subjective aspects such as stability and comfort, thereby improving the accuracy and precision of the evaluation.

[0071] In step S103, an evaluation result of the parking system of the vehicle to be tested is generated according to the evaluation data.

[0072] It is to be understood that the evaluation result refers to an overall score or grade, such as excellent, good and average, used to measure the overall performance level of the parking system.

[0073] Specifically, in the embodiment of the present application, after the user selects a parking product of a certain type of vehicle, a parking scenario library of the system can be formed according to the combination of parking space elements in Table 1, and the parking system can be evaluated and scored for each scenario using the evaluation indicators in Table 2. After all scenarios are evaluated, all scores are integrated and averaged, and the product performance evaluation results and subsequent product improvement directions are obtained according to the evaluation criteria shown in Table 3, where Table 3 is a product performance evaluation standard table.

[0074] Table 3

[0075] Serial number Points evaluate 1 55＜x≤65 excellent 2 35＜x≤55 good 3 x≤35 generally

[0076] The embodiment of the present application helps to improve the accuracy and precision of the evaluation of the vehicle parking system by conducting a detailed evaluation of the parking system and generating an evaluation result based on the evaluation data, and can significantly improve the performance of the system and user experience.

[0077] Optionally, in one embodiment of the present application, generating an evaluation result of the parking system of the vehicle to be tested according to the evaluation data includes: calculating a score of the parking system of the vehicle to be tested according to the evaluation data; and determining the evaluation result according to a score interval of the score.

[0078] Specifically, in combination with what is shown in Table 3, the embodiment of the present application can form a parking scenario library of the system according to the combination of parking space elements in Table 1, and use the evaluation indicators in Table 2 to evaluate and score the parking system for each scenario. After all scenarios are evaluated, all scores are integrated and averaged to obtain the evaluation result of the parking system of the vehicle to be tested. For example, when the score is less than or equal to 35, the evaluation is general; when the score is greater than 35 and less than or equal to 55, the evaluation result is good; when the score is greater than 55 and less than or equal to 65, the evaluation result is excellent.

[0079] The embodiment of the present application can calculate the score of the parking system of the vehicle to be tested based on the evaluation data, and determine the evaluation result based on the score range of the score. Therefore, through an accurate scoring system, the advantages and disadvantages of the system can be accurately identified, which helps to improve product quality and the performance of the parking system, thereby significantly improving user satisfaction and loyalty.

[0080] According to the evaluation method of the vehicle parking system proposed in the embodiment of the present application, a parking scene library of the vehicle to be tested can be generated based on multiple parking space elements, and based on each parking scene in the parking scene library, the parking system of the vehicle to be tested can be evaluated using multiple evaluation indicators to obtain evaluation data, thereby generating an evaluation result of the parking system of the vehicle to be tested based on the evaluation data, which helps to ensure the comprehensiveness and diversity of the test scene, improve the reliability and accuracy of the test results, and effectively evaluate the performance of the automatic parking system. As a result, the problems in the related art that there are still deficiencies in the function and performance constraints and evaluation of automatic parking, which easily lead to the inability to correctly identify the environment, the potential risk of collision, and the possibility of causing the parking process to take a long time and reduce parking efficiency are solved.

[0090] The combination unit is used to combine multiple parking space elements to generate multiple parking scenes;

[0091] A generating unit is used to obtain a parking scenario library based on multiple parking scenarios.

[0092] Optionally, in one embodiment of the present application, the evaluation module 300 includes: a calculation unit and a determination unit.

[0094] The determination unit is used to determine the evaluation result according to the score range in which the score falls.

[0095] It should be noted that the above explanations and descriptions of the embodiment of the evaluation method for a vehicle parking system are also applicable to the evaluation device for a vehicle parking system of this embodiment, and will not be described in detail here.
