[0059] The realization of the purpose, functional features and advantages of this application will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0060] It should be understood that the specific embodiments described here are only used to explain the technical solutions of this application and are not used to limit this application.

[0061] Refer to Figure 1 , Figure 1 It is a structural block diagram of the automated closed-loop test system for the intelligent key and RF antenna of this application.

[0062] The automated closed-loop test system for the intelligent key and the radio frequency antenna includes: an automated test host computer 10, a HIL test platform 20, a CAN interface card 30, and an intelligent key and radio frequency antenna test bench 40. The automated test host computer 10 calls the HIL test platform 20, and data interaction is performed sequentially among the HIL test platform 20, the CAN interface card 30, and the intelligent key and radio frequency antenna test bench 40. The CAN interface card 30 may include a CAN board 302 and a CAN communication card 301.

[0063] In this embodiment, the automated test host computer 10 is configured to send a control instruction to the HIL test platform 20;

[0064] It should be noted that the automated test host computer 10 generally refers to a computer system in an automated control system for monitoring and controlling the lower-level machine. In this application, the automated test host computer 10 can allow the use of the ECUTEST automated test software of the German company ETAS to call the HIL test platform 20 through the provided API interface, design test cases in a simple language, complete human-computer interaction, realize data input / output and monitoring, and the control instructions can cover verifications related to basic signal simulation and acquisition to complex intelligent key and radio frequency antenna tests, enabling the automated test host computer 10 to comprehensively control and monitor the operation of the HIL test platform 20.

[0065] The HIL test platform 20 is configured to receive the control instruction, convert the control instruction into a first CAN message, and send the first CAN message to the CAN interface card 30;

[0066] It should be noted that the HIL test platform 20 is a test environment for simulating and testing the performance of an embedded system or its subsystems in an actual or simulated environment. Software such as NIVeriStand software of the National Instruments company and TCS software of the Hengrun company can be used for real-time data testing and simulation. The first CAN message can be generated according to the information contained in the control instruction and is used to notify the intelligent key and radio frequency antenna of the functions or actions to be performed.

[0067] The CAN interface card 30 is configured to receive the first CAN message and output the first CAN message to the intelligent key and radio frequency antenna test bench 40;

[0068] It should be noted that the CAN interface card 30 can be used to implement data transmission between the automated test host computer 10 and the CAN network and send the first CAN message to the CAN bus.

[0069] The intelligent key and the RF antenna mount 40 are configured to receive the first CAN message, perform tests based on the first CAN message, and obtain a test result signal.

[0070] It should be noted that an intelligent key is an advanced vehicle key technology that enables keyless entry and start functions through wireless communication. Intelligent keys are typically equipped with near-field communication (NFC) or Bluetooth technology, allowing vehicle owners to automatically unlock the doors when approaching the vehicle and start the engine without a traditional key after entering the vehicle. The RF antenna is an essential component in a wireless communication system, responsible for converting electrical signals into radio waves and vice versa for received radio waves.

[0071] When the intelligent key receives the first CAN message, it executes the actions corresponding to the first CAN message. For example, it simulates the action of the vehicle owner pressing the intelligent key button by closing the intelligent key button, and then feeds back the generated test result signal through the RF antenna.

[0072] The CAN interface card 30 is further configured to obtain the test result signal, convert the test result signal into a second CAN message, and output the second CAN message to the HIL test platform 20.

[0073] It should be noted that the test result signal is received via the CAN bus, and the second CAN message carries information including the test result for feedback by the HIL test platform 20.

[0074] The HIL test platform 20 is further configured to receive the second CAN message and send the second CAN message to the automated test host computer 10.

[0075] The automated test host computer 10 is further configured to receive the second CAN message to complete data verification.

[0076] It should be noted that the automated test host computer 10 can analyze and visually display the test results by analyzing the second CAN message to complete data verification.

[0077] Furthermore, the CAN interface card 30 includes a CAN communication card 301.

[0078] The CAN communication card 301 is configured to receive the first CAN message and output the first CAN message to the intelligent key and the RF antenna mount 40.

[0079] The CAN communication card 301 is further configured to obtain the test result signal and convert the test result signal into the second CAN message.

[0080] It should be noted that the CAN communication card 301 generally refers to an expansion card that can be inserted into the host computer, such as a CAN card with PCI or PCIe interfaces. They are installed as internal components of the host computer, can be directly connected to the motherboard of the host computer, and are managed and data-exchanged through the operating system of the host computer. As Figure 2 shown, the CAN communication card 301 participates in the process corresponding to the red line in the figure.

[0081] Furthermore, the CAN interface card 30 includes a CAN board 302;

[0082] The CAN board 302 is used to receive the first CAN message and output the first CAN message to the intelligent key and RF antenna rack 40 through the IO.

[0083] The CAN board 302 is also used to collect the test result signal through the IO port and convert the test result signal into the second CAN message.

[0084] It should be noted that the CAN board 302 refers to an external interface card, such as the CAN interface card 30 with a USB interface. This interface card is connected to the computer through an external interface (such as USB), which is convenient for moving and using between different computers. It can be adaptively developed for the CAN board 302 through keli uvison based on the 8051 single-chip microcomputer development environment. As Figure 2 shown, the CAN board 302 participates in the process corresponding to the blue line in the figure.

[0085] Furthermore, the automated test host computer 10 displays an automated test HIL test software interface, and the automated test HIL test software interface includes a control input area, a collection output area, a control area, and a display area;

[0086] The control input area is used to obtain an input signal and generate a control instruction according to the input signal and output it to the HIL test platform 20;

[0087] The collection output area is used to receive the second CAN message sent by the CAN interface card 30 and output the second CAN message to the HIL test platform 20;

[0088] The control area is used to implement the signal mapping between the first CAN message and the second CAN message;

[0089] The display area is used to achieve the visual display of the first CAN message and the second CAN message based on the signal mapping.

[0090] It should be noted that the input signal can be a signal input through input devices such as the keyboard and mouse of the host computer and the first CAN message. The signal mapping between the first CAN message and the second CAN message can make the first CAN message and the second CAN message obtained based on the same control instruction correspond one by one.

[0091] The automated test HIL test software interface is as Figure 3 shown. The automated test host computer 10 displays the automated test HIL test software interface. Through the operation of the HIL test platform 20 UI interface, it controls the input to send instructions to the intelligent key and the RF antenna, collects the feedback responses of the intelligent key and the RF antenna output, and performs a closed-loop test. Among them, the control area can realize the mapping of hardwired input and output signals (the first CAN message and the second CAN message).

[0092] In this application, the automated test host computer 10 sends a control instruction to the HIL test platform 20; the HIL test platform 20 receives the control instruction, converts the control instruction into a first CAN message, and sends the first CAN message to the CAN interface card 30; the CAN interface card 30 receives the first CAN message and outputs the first CAN message to the intelligent key and RF antenna bench 40; the intelligent key and RF antenna bench 40 receives the first CAN message, performs a test according to the first CAN message, and obtains a test result signal; then, the CAN interface card 30 acquires the test result signal, converts the test result signal into a second CAN message, and outputs the second CAN message to the HIL test platform 20; the HIL test platform 20 receives the second CAN message and sends the second CAN message to the automated test host computer 10; the automated test host computer 10 receives the second CAN message to complete data verification. Since this application can realize the closed-loop test from hardware to software, early intervention in the test shortens the R & D cycle, improves the test efficiency and accuracy, thereby enhancing the reliability and safety of the product.

[0093] The embodiment of the present application provides an automated closed-loop test method for an intelligent key and an RF antenna. Refer to Figure 4 , Figure 4 which is the flow schematic diagram of the first embodiment of an automated closed-loop test method for an intelligent key and an RF antenna in the present application.

[0094] In this embodiment, the automated closed-loop test method for the intelligent key and the RF antenna includes steps S10 to S40:

[0095] Step S10, obtain a signal matrix file;

[0096] It should be noted that the signal matrix file generally refers to a file used to describe the communication relationships among various nodes in a CAN (Controller Area Network) network, which contains information such as CAN signals, nodes, and messages.

[0097] It can be understood that the signal matrix file is the basis for implementing in-vehicle signal simulation, and can be used to simulate vehicle network communication for system testing and verification.

[0098] Step S20: Obtain test cases according to the requirement file and the conversion tool;

[0099] It should be noted that the requirement file can be a text description of the functions to be tested of the device under test, including information such as test conditions, test steps, and expected results. The requirement file can be stored in the form of an Excel table, and by developing a relevant conversion tool, the Excel table can be directly converted into a pkg format file recognizable by the EcuTest automated test host computer 10.

[0100] It can be understood that through automated conversion, the time and workload of manually writing test cases are reduced, significantly improving the efficiency and accuracy of test case generation.

[0101] Step S30: Obtain test instructions according to the test cases and the signal matrix file;

[0102] It should be noted that the test instructions can be CAN messages. By mapping the input and output conditions in the test cases to the specific signals in the signal matrix file, it is determined which signals need to be set (written) or read (output) to construct the test instructions.

[0103] It can be understood that by performing Step S30, the test instructions can accurately reflect the requirements of the test cases, ensuring the accuracy and reliability of system testing.

[0104] Step S40: Control the intelligent key and the RF antenna according to the test instructions to obtain test results.

[0105] It should be noted that the test instructions can include basic function test instructions, signal strength calibration test instructions, response time test instructions, load test instructions, and safety test instructions. The intelligent key is an advanced vehicle key technology that realizes keyless entry and start functions through wireless communication. The intelligent key is usually equipped with near-field communication (NFC) or Bluetooth technology, allowing the vehicle owner to automatically unlock the vehicle door when approaching the vehicle and start the engine without a traditional key after entering the vehicle. The RF antenna is an essential key component in the wireless communication system, responsible for converting electrical signals into radio waves and converting the received radio waves into electrical signals.

[0106] It can be understood that by performing step S40, the basic function automated testing of the smart key and the RF antenna can be achieved, solving the problems of large manual testing workload and long testing cycle. It can also test composite scenarios such as multi-project and multi-vehicle testing and multi-key load testing, expanding the testing scope.

[0107] In a feasible implementation manner, step S40 may include, when the test instruction is a basic function test instruction, controlling the closing or opening of the smart key button and the fixed duration of closing or opening according to the basic function test instruction to obtain a test signal; obtaining the test signal through the RF antenna, and comparing the test signal with the expected signal to obtain a test result.

[0108] It should be noted that the test signal may be the signal fed back by the RF antenna when the smart key button is closed or opened and the fixed duration of closing or opening, and the expected signal may be the signal expected to be obtained when different smart key buttons are pressed.

[0109] Specifically, according to the basic function test instruction, the CAN board 302 is used to control the on-off of the relay, and the smart key button 1, smart key button 2, smart key button 3, smart key button 4, smart key button 5, etc. are closed or opened and the closing or opening duration is controlled, and the test signals of different button responses are fed back through the RF antenna to perform the basic button function test.

[0110] In a feasible implementation manner, step S40 may include, when the test instruction is a signal strength calibration test instruction, adjusting the distance between the smart key and the RF antenna according to the signal strength calibration test instruction; testing the communication quality between the smart key and the RF antenna at different distances; and obtaining a test result according to each communication quality and the corresponding distance.

[0111] It should be noted that the communication quality can be evaluated by measuring the strength of the received signal. The signal strength is usually expressed in dBm (decibel milliwatt), and the smaller the value, the weaker the signal and the worse the communication quality may be.

[0112] Specifically, according to the signal strength calibration test, the CAN board 302 is used to control the operation of the motor to control the distance between the smart key and the RF antenna, test the communication quality between the smart key and the vehicle at different distances, record the communication instructions corresponding to different distances, and complete the calibration-related test.

[0113] In a feasible implementation manner, step S40 may include: when the test instruction is a response time test instruction, recording the start time of pressing the key of the smart key according to the response time test instruction; obtaining the reception time of the signal corresponding to the key of the smart key returned by the RF antenna; obtaining the time interval according to the start time and the reception time; and using the time interval as the test result of the key of the smart key.

[0114] It should be noted that the start time, the reception time, and the time interval can be any real numbers.

[0115] Specifically, after the host computer issues a response time test instruction, record the time interval from pressing the key of the smart key to performing actions such as unlocking and locking the key. △ t.

[0116] In a feasible implementation manner, step S40 may include: when the test instruction is a load test instruction, controlling multiple smart keys to work simultaneously according to the load test instruction; obtaining the load and the response time caused by the simultaneous work of multiple keys; and obtaining the test result according to the load and the response time.

[0117] It should be noted that the load can be evaluated by the host computer monitoring the resource usage conditions (such as CPU usage rate, memory usage amount, etc.), and the response time refers to the response speed to the load test instruction.

[0118] In a feasible implementation manner, step S40 may include: when the test instruction is a security test instruction, controlling the keys of the legal smart key and the illegal smart key to be closed according to the security test instruction; when the keys of the legal smart key and the illegal smart key are both closed, obtaining the RF signal emitted by the RF antenna; and obtaining the test result according to the RF signal.

[0119] It should be noted that frequency information, coding information, and modulation information can be obtained through the RF signal, and thus the RF data information of the smart key can be determined, which can be used to identify and verify the identity of the smart key. By analyzing the RF data, the legal smart key and the illegal smart key are verified.

[0120] In this embodiment, a signal matrix file is imported; test cases are obtained according to a requirements file; test instructions are obtained according to the test cases and the signal matrix file; and intelligent keys and RF antennas are controlled according to different test instructions to obtain corresponding test results. On the one hand, it can realize the automated testing of the basic functions of intelligent keys and RF antennas, solving the problems of large manual testing workload and long testing cycle. On the other hand, it can solve the calibration work of keys and RF antennas, and can also test composite scenarios such as multi-project, multi-vehicle testing and multi-key load testing, expanding the testing scope. Compared with the single function of traditional testing, it ensures the testing integrity and reliability of intelligent keys and RF antennas.

In specific applications, those skilled in the art can set according to needs, and the present application does not limit this.
