[0002] Automatic parking is the most important part of intelligent driving and also the part that improves the driver's experience the most. By using centimeter-level positioning antennas, the real-time positioning error is less than 5cm in a standard test site. It can accurately record the entire parking process, locate the vehicle's position, speed, heading and other information in real time, and automatically identify the parking space the vehicle is about to enter. It can also evaluate the quality of whether the vehicle is crossing the line or the number of times it hits the parking space during the automatic parking process, as well as the final parking position.

[0003] The invention patent with application number 2021103529106 proposes an automatic parking system test evaluation method, device, equipment and storage medium. First, when the current vehicle is detected to enter the preset parking area, a library search instruction is generated, so that the current vehicle starts the parking space detection function according to the library search instruction; then, when the current vehicle detects the parking space, the number of parking space detections of the current vehicle is recorded; further, when the current vehicle completes parking, the parking angle of the vehicle is calculated; finally, a detection report is generated according to the parking angle and the number of parking space detections;

[0004] In order to improve the automatic parking experience, the automatic parking system needs to be tested multiple times to find out its shortcomings. However, the information transmission of the existing automatic parking system will be delayed, and the data delay will cause errors and affect the detection results.

[0005] Moreover, the existing testing environments are all indoor environments, and it is difficult to maintain the level of the initial test when encountering complex outdoor environments. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Figure 1 It is a system block diagram of the present invention.

[0059] Figure 2 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0060] Reference Figure 1 :An automatic parking quality test and evaluation system based on satellite signals, comprising:

[0061] A data acquisition module, the data acquisition module is used to obtain vehicle information and parking area information; it should be noted that the vehicle information includes vehicle positioning information and vehicle operation information, such as position, speed and heading, and the parking area information includes map information of parking spaces;

[0062] The data acquisition module includes four vehicle positioning antennas, four ground positioning antennas and a control console;

[0063] The console is installed outside the parking space, and a plane coordinate system is established with the console as the origin, the left-right direction as the X-axis, and the front-back direction as the Y-axis;

[0064] The four vehicle positioning antennas are used to obtain the wheel coordinates of the vehicle, and the four ground positioning antennas are used to obtain the outer contour coordinates of the parking space;

[0065] Test evaluation module: The test evaluation module is used to evaluate the quality of vehicle parking, specifically:

[0066] The test starts when the vehicle enters the parking area, and the vehicle is considered stopped when the vehicle speed is less than 0.5 km / h;

[0067] Obtain the outer contour coordinates of the parking space;

[0068] Obtain the four-wheel coordinates of the vehicle each time it stops;

[0069] The number of times the test is performed is obtained and marked as W. The initial value of W is 0. When the four-wheel coordinates of the vehicle are not within the outer contour coordinates after the vehicle stops, the value of W is increased by 1 until the four-wheel coordinates of the vehicle are completely within the outer contour coordinates W.

[0070] The parking time score value of the test is obtained and marked as E. The test starts and the time is counted until the four-wheel coordinates of the vehicle are completely within the outer contour coordinates after the vehicle stops. The obtained time is the total parking time of the vehicle. The total parking time of this time is valued according to historical data. The parking time score value is any integer from 1 to 10. In this embodiment, the value can be obtained by obtaining the average parking time of all tests before the current time period and marking it as Q. Set The parking time score is 1, which is the total parking time. Calculate a number between 1 and 10, and round it off to get the parking time score value E;

[0071] The offset score value of the test is obtained and marked as R. After the vehicle stops, if the four-wheel coordinates are not within the outer contour coordinates, the straight-line distance between the four-wheel coordinates of the vehicle and the outer contour coordinates of the corresponding adjacent parking space is recorded until the four-wheel coordinates of the vehicle are completely within the outer contour coordinates. All the recorded distances are combined into the total offset value of the test. The offset score value R is determined according to the total offset value based on the experience of the staff. In this embodiment, the value determination method can be to set a total offset value threshold T in advance. If the total offset value is greater than the threshold T, the offset score value is 11. If the total offset value is less than the threshold T, the total offset value is used. Calculate a number between 1 and 10, and round it off to get the offset score value R;

[0072] The parking posture score value of the test is obtained and marked as Y. The four-wheel coordinates of the vehicle when the four-wheel coordinates are within the outer contour coordinates after the vehicle stops are obtained. The straight-line distance between the four-wheel coordinates of the vehicle and the outer contour coordinates of the corresponding adjacent parking space is recorded. The difference between the maximum and minimum values ​​of the four sets of straight-line distances is obtained. The parking posture score value Y is determined according to the difference based on the experience of the staff. In this embodiment, the value determination method can be, for example, if the difference is between 0 and 10 centimeters, the parking posture score value Y is 1 point; if the difference is between 10 and 20 centimeters, the score value Y is 2 points; if the difference is between 20 and 30 centimeters, the score value Y is 3 points; and so on.

[0073] The quality score value U of the test is calculated according to the formula U=(W×a1)+(E×a2)+(R×a3)+(Y×a4), where a1, a2, a3 and a4 are pre-set weight coefficients; these weights are set based on expert experience, statistical data analysis or relevant regulations and standards. In this embodiment, since the number of times the vehicle is adjusted during the parking process, too many adjustments may lead to reduced parking efficiency and increase the potential risk to surrounding vehicles or pedestrians, this indicator may require a higher weight;

[0074] Parking time is an important indicator for measuring parking efficiency. In a busy parking lot or urban environment, completing parking quickly can reduce the impact on traffic flow. However, compared with safety and accuracy, time may not be the primary consideration. Therefore, the weight of this indicator can be moderate;

[0075] The offset reflects the accuracy of vehicle parking. A vehicle with a large offset may cause irregular parking and even affect the use of other parking spaces. Therefore, it should be given a higher weight;

[0076] The parking posture score reflects the posture of the vehicle after it is parked, including whether the vehicle is neatly parked in the parking space and the distance from other vehicles or obstacles. It is directly related to an indicator of parking quality and therefore may require the highest weight;

[0077] Therefore, the values ​​of a1, a2, a3 and a4 can be 0.256, 0.134, 0.325 and 0.285 respectively.

[0078] A quality score threshold value P is set in advance. If the quality score value U is greater than the quality score threshold value P, the automatic parking mode is adjusted. If not, it means that the automatic parking is qualified.

[0079] The signal receiving module includes a base station unit, which is used to obtain the information obtained by the data acquisition module, transmit it to the test evaluation module, and keep the data updated in time. The base station unit includes two satellite signal receiver devices, one outputs KSXT statements, and the other outputs GPNTR statements. The base station unit includes 2 peripheral software assistance: virtual serial port service management software and XCOM monitoring software; it should be noted that the base station is established and the differential data is broadcast through the radio; it should be noted that the actual use process is as follows:

[0080] Set one of the mobile stations to input KSXT statements from the serial port and output a frequency of 5HZ. After setting, let it work normally. The device is set up and marked as device A.

[0081] Set another mobile station to input GPNTR statement from the serial port and output frequency 5HZ. After setting, let it work normally. The device is set up and marked as B device.

[0082] Prepare three serial port cables, one of which is connected to device A, one is connected to device B, and the other is used as the data output printing serial port (for wired communication mode).

[0083] The serial port is defined and set through the virtual serial port service management software and XCOM monitoring software. When the communication mode is wired communication mode, the positioning port is the actual serial port number; the output port is COM88; the XCOM software monitoring port is COM89. When the communication mode is wireless communication mode, the positioning port is COM10; the output port is COM65; the XCOM software monitoring port is COM20. The XCOM monitoring software automatically reads the vehicle information from the configured serial port and displays it in the dialog box. After the test is completed, the dialog box will display the vehicle's location information after parking, the line pressing situation during parking, and the storage rubbing situation. Users can clearly understand the automatic parking process.

[0084] As an optional embodiment, the specific manner in which the data acquisition module obtains the coordinate information of the vehicle is as follows:

[0085] The four vehicle positioning antennas are electrically connected to the control console, and the four vehicle positioning antennas are electrically connected to the satellite signal receiver device outputting KSXT;

[0086] The four vehicle positioning antennas are respectively installed at the four corners of the outer contour of the vehicle; it should be noted that the coordinates of the four positioning antennas relatively map the coordinates of the four wheels of the vehicle, which are used to transmit the four-wheel coordinates of the vehicle to the console to obtain the four-wheel coordinate information of the vehicle.

[0087] As an optional embodiment, the specific manner in which the data acquisition module obtains parking space coordinate information is as follows:

[0088] The four ground positioning antennas are placed at four corners of the outer contour of the parking space respectively;

[0089] The four ground positioning antennas are electrically connected to the control console, and the four ground positioning antennas are electrically connected to the satellite signal receiver device that outputs KSXT. The four ground positioning antennas transmit the position information to the control console to obtain the coordinate information of the four corners of the outer contour of the parking space. It should be noted that the outer contour of the parking space is generally a rectangle, and the coordinate information of the outer contour of the parking space can be known based on the coordinate information of the four corners.

[0090] As an optional embodiment, the test evaluation module further includes an experience evaluation unit, and the experience evaluation unit is used to test the comfort experience of the user in the automatic parking, specifically:

[0091] The smoothness score value during the test is obtained and marked as S. It should be noted that the smoothness score value S is used to indicate whether the lateral and longitudinal movements of the vehicle are coordinated and unified during the parking process, and whether there are obvious pauses and jams;

[0092] The comfort score value during the test is obtained and marked as F. It should be noted that the comfort score value F is used to indicate the stability of the vehicle's lateral movement during parking, the severity of acceleration and deceleration, etc., which directly affects the comfort of user experience.

[0093] The experience score value G of this test is calculated according to the formula G=(S×b1)+(F×b2), where b1 and b2 are preset weight coefficients. These weights are set based on expert experience, statistical data analysis or relevant regulations and standards. In this embodiment, the values ​​of b1 and b2 can be 0.478 and 0.522.

[0094] The experience score value G is used to assist in obtaining the quality score value H after the reference user experience. The quality score value H after the reference user experience is calculated according to the formula H=(G×c1)+(U×c2), where c1 and c2 are pre-set weight coefficients. These weights are set based on expert experience, statistical data analysis or relevant regulations and standards. Although user experience is important, it is secondary compared to the safety and quality of parking. Therefore, in this embodiment, the values ​​of b1 and b2 can be 0.217 and 0.783.

[0095] As an optional embodiment, the fluency score value S in the test process is obtained as follows, specifically:

[0096] The fluency score value S during the test is obtained by calculation according to the formula S=1-W.

[0097] As an optional embodiment, an adaptability test module is further included, and the adaptability test module includes an environment simulation unit and an adaptability test unit. The environment module unit is used to change the environment and obstacle position of the parking area, specifically:

[0098] The environmental module unit includes a lighting device installed at the top of the parking area, a fan device installed on the wall of the parking area and an obstacle device with a self-driving function; it should be noted that the parking area is a sealed area, and the light intensity is entirely provided by the lighting device. The light intensity in the parking area is adjusted by changing the intensity of the lighting device, and the wind speed in the parking area is adjusted by turning on or changing the power of the fan device. The obstacle device is initially located at the edge of the parking area and does not block the parking route. The presence of an obstacle in the parking route is changed by changing the position of the obstacle, and the obstacle device is composed of a driving member at the lower end and an obstacle at the upper end. In this embodiment, the driving member may be an electric roller.

[0099] As an optional embodiment, the adaptability test unit is used to perform quality evaluation on the automatic parking test after the environment and obstacles are changed, specifically:

[0100] Three environmental impact levels are set in advance, marked as the first environmental impact level, the second environmental impact level and the third environmental impact level;

[0101] At the first environmental impact level, the light intensity is between 300-500 Lux; this range provides good visibility while avoiding interference to the sensor caused by excessive light;

[0102] Wind speed: less than 5m / s; slight wind speed will not have a significant impact on the stability of the vehicle and the parking process.

[0103] The obstacle is located at the edge or corner of the parking area; it is far away from the parking path and does not affect the driving of the vehicle.

[0104] In the second environmental impact level, the light intensity is between 100-300 Lux. Light within this range may have a certain impact on the recognition ability of the sensor, but it is still within an acceptable range.

[0105] Wind speed: 5-10m / s; Moderate wind speed may have a certain impact on the vehicle's driving stability, requiring the automatic parking system to make corresponding adjustments.

[0106] The obstacle is located within the parking area and may interfere with the parking route to some extent, but it is not a complete obstruction;

[0107] In the third environmental impact level, the light intensity is between 0-100 Lux. In such low light conditions, the sensors of the automatic parking system may need additional auxiliary equipment to improve recognition capabilities.

[0108] Wind speed: greater than 10m / s; strong winds may have a significant impact on the control and stability of the vehicle, and the automatic parking system needs to have strong anti-interference capabilities.

[0109] Obstacles located at key locations within the parking area, such as on the parking path or near the vehicle's driving route, pose a major challenge to the parking process.

[0110] The quality score values ​​tested under the first environmental impact level, the second environmental impact level, and the third environmental impact level are obtained and marked as X, V, and M respectively; it should be noted that the method for obtaining the quality score values ​​tested under the first environmental impact level, the second environmental impact level, and the third environmental impact level is the same as the above calculation method, and it should also be noted that the quality score value H after the reference user experience after the above calculation is the same as the quality score value X under the first environmental impact level.

[0111] As an optional embodiment, X, V, and M are compared. If X is less than V, it means that the automatic parking test has failed and needs further optimization. If X is equal to V and less than M, it means that the automatic parking test has passed, but needs to be optimized for extreme environments. If X is equal to V and equal to M, it means that the automatic parking test has passed and the environmental impact is small.

[0112] like Figure 2 As shown: The present invention also proposes an automatic parking quality test and evaluation method based on satellite signals, comprising the following steps:

[0113] Step 1: Collect the vehicle's operating information and the coordinate information of the vehicle and the parking area;

[0114] Step 2: Establish a base station unit, obtain the real-time information of the vehicle through the base station unit and transmit it;

[0115] Step 3: Evaluate the quality of the automatic parking test based on the information obtained.

[0116] Working principle: By setting up a test evaluation module and a signal receiving module, the whole parking process can be accurately recorded, the position, speed, heading and other information of the vehicle can be located in real time, and the parking space that the vehicle is about to enter can be automatically identified. The quality of whether the vehicle is crossing the line or rubbing the parking space during the automatic parking process and the final parking position can be evaluated. In addition, an accurate evaluation score can be given based on the user experience comfort and accuracy, which is helpful for users to find problems in the parking process.

[0117] By setting up an adaptive test module, the complex parking environment of the outside world can be simulated as needed, and evaluation scores can be given according to different environments, which is conducive to observing the changes in test data of parking in complex environments.

[0118] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technical staff in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of this template.
