It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.
[0024] Firstly, embodiments of this application provide a vehicle testing system, such as... Figure 1 As shown, the test system includes a status control module 200, a network communication module 300, a human-computer interaction module 400, a result verification module 500, and a main control module 100.
[0025] The state control module 200 is used to simulate physical operations on the vehicle to detect the vehicle's motion control process. The state control module 200 provides realistic physical triggering conditions for whole vehicle testing, such as detecting the response of physical actions like unlocking, locking, and pressing the brake pedal 900. It maintains the same physical operations for each vehicle under test to avoid differences in operation actions and meet test consistency requirements.
[0026] The network communication module 300 is used to communicate with the vehicle to detect its operating status. The network communication module 300 interacts with the vehicle's underlying network to detect the stability of the vehicle's network communication and the logic of operating status switching, such as controlling and detecting gear shifting. The network communication module 300 sends messages using an independent thread, without affecting the operation of other modules, ensuring a smooth testing process.
[0027] The human-machine interaction module 400 is used to simulate the human-machine interaction process to operate the vehicle's central control system, thereby testing the vehicle's central control system. The human-machine interaction module 400 simulates the human-machine interaction process through various human-machine interaction methods, such as voice, touch click, or control of the central control system through data commands, to meet the accuracy requirements of human-machine interaction testing.
[0028] The result verification module 500 is used to verify the test results of the status control module 200, network communication module 300, and human-computer interaction module 400. After the status control module 200, network communication module 300, and human-computer interaction module 400 are tested, the result verification module 500 performs photo verification to ensure the traceability of the testing process and improve the authenticity and reliability of the test results.
[0029] The main control module 100 generates testing commands and controls the status control module 200, network communication module 300, human-machine interaction module 400, and result verification module 500 according to these commands to achieve whole-vehicle testing. As the system core, the main control module 100 coordinates the testing process of the status control module 200, network communication module 300, human-machine interaction module 400, and result verification module 500, enabling collaboration among the modules, ensuring testing accuracy, and improving testing efficiency.
[0030] The main control module 100 controls the status control module 200 to simulate the physical operation of the vehicle and detect the vehicle's motion control process; the control network communication module 300 communicates with the vehicle to detect the vehicle's operating status; and the control human-machine interaction module 400 simulates the human-machine interaction process to operate the vehicle's central control system and detect the vehicle's central control system. After each test, the test results are verified by the verification module. The control process can be adjusted and customized in the main control module 100 to meet the needs of different vehicle models.
[0031] This application also provides another vehicle testing system, such as... Figure 2 As shown, the test system includes a status control module 200, a network communication module 300, a human-computer interaction module 400, a result verification module 500, a remote control module 600, and a main control module 100.
[0032] The status control module 200 is used to simulate the physical operation of the vehicle in order to detect the vehicle's motion control process.
[0033] In one embodiment, the status control module 200 includes multiple relay modules connected to the main control module 100 via a serial port. The relay modules are used to simulate the unlocking or locking operation of the vehicle's remote key 700; and / or, the relay modules are used to control the brake pedal control device 800 to simulate the operation of pressing or releasing the vehicle's brake pedal 900.
[0034] like Figure 3 As shown, the multiple relay modules include a first relay module 201, a second relay module 202, a third relay module 203, and a fourth relay module 204. The first relay module 201 and the second relay module 202 are used to simulate the unlocking or locking operation of the vehicle's remote key 700, while the third relay module 203 and the fourth relay module 204 are used to simulate the operation of pressing or releasing the vehicle's brake pedal 900.
[0035] The remote control key 700 includes a first power supply 701, with a first branch 702 and a second branch 703 connected in parallel between the positive and negative terminals of the first power supply 701; an unlocking signal transmitter 704 is provided on the first branch 702, and a locking signal transmitter 705 is provided on the second branch 703; a first relay module 201 is electrically connected to the first branch 702 and is used to control the on / off state of the first branch 702; a second relay module 202 is electrically connected to the second branch 703 and is used to control the on / off state of the second branch 703.
[0036] The first power supply 701 is a built-in power supply device for the remote key 700, such as a battery. The positive and negative terminals of the first power supply 701 form a power supply circuit through a first branch 702 and a second branch 703 connected in parallel. The first branch 702 has an unlock signal transmitter 704, which is used to send an unlock signal to the vehicle, corresponding to the unlock function. The second branch 703 has a lock signal transmitter 705, which is used to send a lock signal to the vehicle, corresponding to the lock function.
[0037] The remote control key 700 also includes an unlock button 706 and a lock button 707. The unlock button 706 is connected in series in the first branch 702, and the lock button 707 is connected in series in the second branch 703. The unlock button 706 and lock button 707 are physical buttons. The unlock button 706 controls the on / off state of the first branch 702 to control the unlock signal transmitter 704 to send a signal; the lock button 707 controls the on / off state of the second branch 703 to control the lock signal transmitter 705 to send a signal. Since the physical buttons 706 and 707 are not convenient for automated control, a first relay module 201 and a second relay module 202 are connected. The first relay module 201 and the second relay module 202 replace the functions of the unlock button 706 and the lock button 707, and can be electrically controlled to achieve automated control of the on / off state of the first branch 702 and the second branch 703.
[0038] In the initial state, both the first relay module 201 and the second relay module 202 are normally open, that is, both the first branch 702 and the second branch 703 are in the open state.
[0039] When the test process requires unlocking the vehicle, the main control module 100 sends a control command to the first relay module 201 via the serial port, causing the first relay module 201 to be in a closed state, the first branch 702 to be turned on, the first power supply 701 to supply power to the unlock signal transmitter 704, the unlock signal transmitter 704 to send an unlock signal to the vehicle, and detects whether the vehicle is unlocked normally. After unlocking is completed, the main control module 100 sends a control command to the first relay module 201, causing the first relay to be in a closed state.
[0040] When the test process requires locking the vehicle, the main control module 100 sends a control command to the second relay module 202 via the serial port, causing the second relay module 202 to be closed, the second branch 703 to be turned on, the first power supply 701 to supply power to the locking signal transmitter 705, the locking signal transmitter 705 to send a locking signal to the vehicle, and detects whether the vehicle is locked normally. After locking is completed, the main control module 100 sends a control command to the second relay module 202, causing the second relay to be opened.
[0041] The first relay module 201 and the second relay module 202 realize automated control of unlocking and locking. The triggering conditions for unlocking or locking remain consistent each time, which improves the accuracy of the test results comparison. Moreover, unlocking and locking do not interfere with each other, meeting the timing requirements in the test process.
[0042] like Figure 4As shown, the brake pedal control device 800 includes a second power supply 801 and an electric telescopic rod 802. A third relay module 203 and a fourth relay module 204 are connected in series between the second power supply 801 and the electric telescopic rod 802. The third relay module 203 and the fourth relay module 204 are used to control the extension and retraction direction of the electric telescopic rod 802. The electric telescopic rod 802 is used to control the position of the brake pedal 900 to simulate the operation of pressing or releasing the brake pedal 900.
[0043] The second power supply 801 provides a stable power supply to the electric telescopic pole 802, which can perform linear telescopic movement to drive the brake pedal 900 to move. In one embodiment, the electric telescopic pole 802 is located between the brake pedal 900 and the steering column 1000. The distance between the brake pedal 900 and the steering column 1000 is generally between 20-30cm. To ensure the displacement effect of the electric telescopic pole 802, the stroke of the electric telescopic pole 802 is 4-6cm, and the movement speed is 0.5-2.5cm / s. For example, an electric telescopic pole 802 with a stroke of 5cm and a movement speed of 1.5cm / s.
[0044] The normally open and normally closed interfaces of the third relay module 203 are connected to the electric telescopic rod 802, and the common interface is connected to the negative terminal of the second power supply 801. The normally open and normally closed interfaces of the fourth relay module 204 are connected to the electric telescopic rod 802, and the common interface is connected to the positive terminal of the second power supply 801.
[0045] The positive terminal of the second power supply 801, the common interface of the fourth relay module 204, the normally closed interface of the fourth relay module 204, the electric telescopic rod 802, the normally closed interface of the third relay module 203, the common interface of the third relay module 203, and the negative terminal of the second power supply 801 form a positive path. At this time, the electric telescopic rod 802 moves away from the brake pedal 900.
[0046] The positive terminal of the second power supply 801, the common interface of the fourth relay module 204, the normally open interface of the fourth relay module 204, the electric telescopic rod 802, the normally open interface of the third relay module 203, the common interface of the third relay module 203, and the negative terminal of the second power supply 801 form a reverse path. At this time, the electric telescopic rod 802 moves towards the brake pedal 900, driving the brake pedal 900 to move.
[0047] Initially, with the path open in the positive direction, the electric telescopic rod 802 maintains its furthest distance from the brake pedal 900, avoiding contact. When the brake pedal 900 needs to be depressed, the main control module 100 sends control commands to the third relay module 203 and the fourth relay module 204 via serial port. The normally open and normally closed interfaces of the third relay module 203 and the fourth relay module 204 switch their open and closed states, forming a path in the opposite direction. The electric telescopic rod 802 moves closer to the brake pedal 900, driving the brake pedal 900 to move. When the brake pedal 900 needs to be released, the main control module 100 sends control commands to the third relay module 203 and the fourth relay module 204 via serial port. The normally open and normally closed interfaces of the third relay module 203 and the fourth relay module 204 switch their open and closed states, restoring the path in the positive direction. The electric telescopic rod 802 moves away from the brake pedal 900, releasing the brake pedal 900.
[0048] The third relay module 203 and the fourth relay module 204 can precisely control the pedal displacement and pedal time of the brake pedal 900, ensuring that the triggering conditions for each braking action are consistent and improving the accuracy of the test results.
[0049] The network communication module 300 is used to communicate with the vehicle to detect its operating status. The network communication module 300 sends simulated messages to the vehicle via a separate thread. These simulated messages include at least a checksum, a safety signal, and a gear position command. In one embodiment, the network communication module 300 communicates with the vehicle in real time via a CANFD communication card.
[0050] Checksums are used by vehicles to verify simulated messages to determine their security. Checksums are identifiers used to verify the data integrity and security of simulated messages. For example, Cyclic Redundancy Check (CRC) allows vehicles to verify whether messages have been tampered with, lost, or corrupted during transmission, ensuring that received commands are authentic and reliable, and preventing erroneous vehicle responses due to invalid messages.
[0051] The life signal is used by the vehicle to detect analog messages to confirm that communication with the vehicle remains continuous. The life signal proves to the vehicle that the network communication module 300 is in normal working order, maintaining the continuous effectiveness of the communication link and preventing the vehicle from judging that communication has been interrupted due to the lack of a valid signal for an extended period, thereby triggering the fault protection mode.
[0052] Gear shift commands are used to control the vehicle to change gears, thereby altering the vehicle's operating state and enabling the detection of this state. These commands are encapsulated in simulated messages and control the vehicle to change gears, such as from P to D, thereby changing the vehicle's operating state and allowing for the detection of the vehicle's gear shifting logic, power response, and the effectiveness of its interaction with components such as the brake pedal and steering wheel.
[0053] The human-machine interaction module 400 is used to simulate the human-machine interaction process to operate the vehicle's central control system, in order to detect the vehicle's central control system; such as... Figure 5 As shown, the human-computer interaction module 400 includes a voice playback module 401, an external physical click module 402, and a data transmission module 403.
[0054] The voice playback module 401 is used to control the vehicle's central control system via analog voice, and to perform tests on the vehicle's central control system. The voice playback module 401 can send analog voice through a speaker. The analog voice can be preset, such as turning on the air conditioner or navigating to the target address. The central control system recognizes and parses the analog voice and executes the corresponding operation, and checks whether the operation is executed correctly.
[0055] The external physical click module 402 is used to control the vehicle's central control system via an external clicker, and to perform tests on the vehicle's central control system. The external physical click module 402 can simulate the operation of pressing a finger on the central control system screen through mechanical touch, and send control commands to the central control system by physically clicking the screen. The central control system executes the corresponding operation according to the control command, and checks whether the operation is executed correctly.
[0056] The data transmission module 403 is used to control the vehicle's central control system by sending control commands, and to detect the vehicle's central control system. The data transmission module 403 directly connects to the central control system's operating system, for example, directly connecting to the central control system's real-time operating system (QNX, Neutrino Real-Time Operating System) via Secure Shell Protocol (SSH), sending control commands, and the central control system executes corresponding operations according to the control commands, and detects whether the operations are executed correctly.
[0057] The result verification module 500 is used to verify the detection results of the state control module 200, network communication module 300, and human-machine interaction module 400. The result verification module 500 includes multiple vision sensors used to collect the test results of the state control module 200, network communication module 300, and human-machine interaction module 400. The vision sensors can be fixed with brackets to capture images of the central control system and instrument panel screens, as well as components such as doors, windows, lights, or wheels.
[0058] The remote control module 600 is used for remotely controlling a vehicle to detect the remote control capability. The remote control module 600 can connect to an application on a mobile phone, allowing the application to send control commands to the vehicle. The vehicle then executes the corresponding operations based on the control commands, and the module checks whether the operations are executed correctly.
[0059] The main control module 100 is used to generate detection commands and control the status control module 200, network communication module 300, human-machine interaction module 400 and result verification module 500 according to the detection commands, so as to realize the whole vehicle test.
[0060] The main control module 100 includes an interactive interface module 101, a detection command generation module 102, and a detection control module 103.
[0061] The interactive interface module 101 is used to receive detection requirement data. In one embodiment, such as... Figure 6 As shown, the interactive interface module 101 has a graphical user interface (GUI). The GUI is developed based on the Python tkinter library and packaged into an executable file that does not require a Python environment using the PyInstaller tool. The GUI includes drop-down menus for setting detection parameters, such as CAN message ID, verification algorithm, SSH login credentials, and screen click coordinates. Alternatively, test items can be selected via checkboxes, such as Bluetooth unlocking, air conditioning settings, and navigation application testing. Testers can flexibly combine these checkboxes to select the items to be tested. By selecting the items to be tested through drop-down menus or checkboxes, testers generate the required testing data.
[0062] The graphical user interface also has a start test button and a stop test button to control the start and stop of the test process. When the test is started, a log display box scrolls to show detailed logs of the test execution process in real time.
[0063] The detection instruction generation module 102 is used to generate detection instructions based on the detection requirement data. The detection instruction generation module 102 analyzes the detection requirement data, determines the items that need to be detected, and generates detection instructions based on the items to be detected. The detection instructions are used by the status control module 200, network communication module 300, human-computer interaction module 400, and result verification module 500 to execute the detection process.
[0064] The detection control module 103 is used to control the status control module 200, network communication module 300, human-machine interaction module 400 and result verification module 500 according to the detection instructions, so as to realize the whole vehicle test.
[0065] In one embodiment, the detection process is as follows: Figure 7 As shown.
[0066] The testing personnel configure the stress test items in the interactive interface module 101, select the items to be tested, configure the stress test information, determine the test parameters, and generate test instructions.
[0067] The test is started by pressing the "Start Test" button in the interactive interface module 101. The detection control module 103 starts and initializes the control status control module 200, network communication module 300, human-computer interaction module 400, and result verification module 500.
