Description

Technical Field

[0001] This invention relates to the field of manufacturing testing, and more specifically, to a digital key testing method, system, digital key, and storage medium. Background Technology

[0002] Digital keys, often called Bluetooth keys or virtual keys, primarily utilize Near Field Communication (NFC) technology. This allows users to unlock and lock car doors and start the vehicle using NFC-enabled smartphones or wearable smart devices, such as smartwatches and wristbands. This significantly improves the convenience of car ownership by enabling owners to unlock and operate their vehicles via smartphones or wearable devices. A digital key replaces the traditional car key, unlocking the vehicle, starting the engine, and monitoring the number of times the car has been opened, sending real-time vehicle status information to your phone. You can even grant unlocking and driving permissions to family and friends using the digital key, while still maintaining the functionality of a physical key.

[0003] In digital keys, automatic unlocking when approaching a car is a frequently used feature. Currently, the common method for testing the response time performance of the car unlocking scenario is manual testing. However, manual testing involves the walking speed of a person, which cannot be controlled. Even if the same person makes multiple round trips between two points, the time taken will vary. Manual testing also involves the angle at which a person walks towards the car. Even if the speed is the same, the angle deviation will cause distance errors, ultimately leading to test errors. Furthermore, manual time difference calculation has a relatively large error. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a digital key testing method, system, digital key, and storage medium, which can solve the testing errors caused by manual testing by different people, meet the reproducibility of test results, make performance test data more reliable, and help improve product experience and product market competitiveness.

[0005] This invention provides a digital key testing method, the method comprising: S1: Obtain test site information; S2: Draw a digital map based on the site information, and determine the delay line of the response terminal based on the digital map; the delay line is a straight line perpendicular to the response terminal; S3: Send an unlock signal to the response terminal on the delay line, and record the time of sending the unlock signal as the first time; S4: Obtain the unlock signal to get a response signal, and record the time when the response signal is emitted as the second time; S5: Determine the response time of the terminal under test based on the first time and the second time, and complete the vehicle digital key response time performance test.

[0006] Preferably, the response terminal is the vehicle end, specifically the vehicle door.

[0007] Preferably, step S1 specifically includes: The response terminal activates the lidar and moves around the test site to collect site information.

[0008] Preferably, the process of drawing a digital map specifically includes: A digital map with a 1:1 scale to the response terminal is generated based on the site information.

[0009] In the above technical solution, the vehicle activates the lidar and moves it around the test site, sending the collected site information to the host computer to generate a 1:1 digital map. By drawing a real-time digital map, the accuracy and reliability are improved because the data is collected in real time. Furthermore, the digital map allows for real-time positioning of both the test terminal and the response terminal, eliminating the need to adjust to specific locations for testing. This ensures data reliability and makes the testing process more convenient.

[0010] Preferably, step S3 specifically includes: S31: The distance M meters from the response terminal on the delay line is determined as the unlocking critical point; where M is a rational number greater than zero.

[0011] S32: The starting point is determined as N meters away from the response terminal on the delay line; where N is a rational number greater than zero and greater than M.

[0012] S33: Move at a constant speed from the starting point toward the unlocking critical point, and when the unlocking critical point is reached, send the unlocking signal to the response terminal, and record the time of sending the unlocking signal as the first time.

[0013] In the above technical solution, the unlocking threshold is defined by the requirements of the terminal under test. Preferably, the terminal under test can be a digital key. For example, if the key is defined as 5 meters away from the vehicle body for unlocking, then the unlocking threshold needs to be defined as 5 meters or more away from the vehicle body. Correspondingly, the distance from the starting point should be greater than the distance from the unlocking threshold, such as 7 meters. It should be understood that the digital key is placed on a high-precision vehicle, which travels at a constant speed from the starting point to the unlocking threshold. After reaching the unlocking threshold, the host computer outputs the time to reach the threshold. The high-precision vehicle solves the testing error caused by manual testing by different people, making the performance test data more reliable and helping to improve the product experience and product market competitiveness.

[0014] Preferably, the determining the response time of the terminal under test according to the first time and the second time specifically includes: The response time of the terminal under test is equal to the second time minus the first time.

[0015] The accuracy of the response time is at the millisecond level.

[0016] In the above technical solution, the digital key is placed on a high-precision trolley, which travels at a constant speed from the starting point to the unlocking critical point. After reaching the unlocking critical point, the upper computer outputs the time of reaching the critical point in the format of yyyy year aa month dd day HH hour mm minute ss second SSS millisecond. At this time, the unlocking signal of the digital key is received by the vehicle end, and the CAN device is connected to the CAN bus to obtain the sending time of the door opening signal in the format of yyyy year aa month dd day HH hour mm minute ss second SSS millisecond. The digital key response time is equal to the door opening signal sending time minus the time of reaching the unlocking critical point. The calculation result on the one hand satisfies the reproducibility of the test result, and on the other hand makes the performance test data more reliable, which helps to improve product experience and product market competitiveness.

[0022] The movable device is configured to respond to a control instruction of the upper computer, and move the terminal under test uniformly according to the control instruction.

[0023] The upper computer is configured to draw a digital map of the test site according to the acquired site information, and to acquire and calculate the first time when the unlocking signal is sent and the second time when the response signal is sent, so as to complete the response performance test of the vehicle-mounted digital key.

[0024] Preferably, the terminal under test at least includes: A communication module, configured to connect to the upper computer; A storage module is used to store control commands from the host computer; The system also includes a processing module, which is connected to the communication module and the storage module, respectively, for receiving control commands from the host computer and sending the unlock signal to the response terminal according to the control commands.

[0025] Preferably, the host computer connects to the CAN bus of the response terminal via a CAN device and obtains the response signal via the CAN bus.

[0026] As another preferred embodiment, the present invention also provides a digital key, wherein the digital key is the terminal under test described above.

[0027] As another preferred embodiment, the present invention also provides a storage medium located in any control unit, the storage medium including a computer program executable by a processor, the computer program being used to perform the digital key testing method as described above.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows: By creating real-time digital maps, the accuracy and reliability are enhanced due to the real-time data acquisition. Furthermore, the digital map allows for real-time location tracking of both the tested and responding terminals, eliminating the need for adjustments to specific locations during testing. This ensures data reliability and makes the testing process more convenient. The high-precision vehicle eliminates the testing errors inherent in manual testing by different personnel, resulting in more reliable performance test data and saving manpower and resources.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] Please refer to Figure 1In a preferred embodiment, the present invention provides a digital key testing method, the method comprising: S1: Obtain test site information; S2: Draw a digital map based on the site information, and determine the delay line of the response terminal based on the digital map; the delay line is a straight line perpendicular to the response terminal; S3: Send an unlock signal to the response terminal on the delay line, and record the time of sending the unlock signal as the first time; S4: Obtain the unlock signal to get a response signal, and record the time when the response signal is emitted as the second time; S5: Determine the response time of the terminal under test based on the first time and the second time, and complete the vehicle digital key response time performance test.

[0037] In the specific implementation process, the vehicle-side LiDAR is activated and moves around the test site, sending the collected site information to the host computer to generate a 1:1 digital map. By drawing a real-time digital map, on the one hand, because the digital map is collected in real time, it is more accurate and reliable; on the other hand, under the digital map, the test terminal and the response terminal can be located in real time regardless of their location, without the need to adjust to a specific location for testing, ensuring data reliability and making the testing process more convenient.

[0040] S33: Move at a constant speed from the starting point towards the unlocking critical point, send the unlocking signal to the response terminal when reaching the unlocking critical point, and record the time when the unlocking signal is sent as the first time.

[0041] In the specific implementation process, the unlocking critical point is defined by the requirements of the terminal under test. Preferably, the terminal under test may be a digital key. For example, if the proximity unlocking of the key is defined as being 5 meters away from the vehicle body, the unlocking critical point needs to be defined at 5 meters or more than 5 meters away from the vehicle body. Correspondingly, the distance of the starting point shall be greater than the distance of the unlocking critical point, such as 7 meters. It should be understood that the digital key is placed on a high-precision trolley, which travels from the starting point to the unlocking critical point at a constant speed. After reaching the unlocking critical point, the upper computer outputs the time of reaching the critical point. The high-precision trolley solves the test error caused by manual tests conducted by different people, making the performance test data more reliable, which helps to improve product experience and product market competitiveness.

[0042] In some embodiments, the determining the response time of the terminal under test according to the first time and the second time specifically includes: The response time of the terminal under test is equal to the second time minus the first time.

[0043] The precision of the response time is at the millisecond level.

[0044] In the specific implementation process, the digital key is placed on a high-precision trolley, which travels from the starting point to the unlocking critical point at a constant speed. After reaching the unlocking critical point, the upper computer outputs the time of reaching the critical point in the format of yyy year aa month dd day HH hour mm minute ss second SSS millisecond. At this time, the unlocking signal of the digital key is received by the vehicle end, and the door opening signal sending time is obtained by connecting the CAN device to the CAN bus, in the format of yyyy year aa month dd day HH hour mm minute ss second SSS millisecond. The digital key response time = door opening signal sending time - time of reaching the unlocking critical point. The calculation result, on the one hand, satisfies the reproducibility of the test results, and on the other hand makes the performance test data more reliable, which helps to improve product experience and product market competitiveness.

[0049] The terminal under test is used to respond to the control commands of the host computer and send the unlock signal to the responding terminal according to the control commands.

[0050] The movable device is used to respond to control commands from the host computer and move the terminal under test uniformly according to the control commands.
