[0002] The "offline" of a vehicle usually refers to an important stage before a new car is assembled from the production line and is ready to be delivered to dealers or customers. At this stage, the vehicle will undergo a series of functional tests to ensure that it meets factory standards.

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.

[0034] The following is a description of the functional self-detection method, device, vehicle and storage medium of the vehicle off-line of the embodiment of the present application with reference to the accompanying drawings. In view of the technical problems such as the time-consuming manual detection and the difficulty in ensuring the integrity and accuracy of the detection items in the related technologies mentioned in the above background technology, the high cost of equipment detection, the low convenience of operation, the poor flexibility, and the difficulty in supporting the functional reliability detection, the present application provides a functional self-detection method for the vehicle off-line, in which the vehicle self-test signal can be responded to, the vehicle controller configuration code of the vehicle can be read to obtain the functional configuration state of the vehicle, thereby combining the test function list matched by the functional configuration state and the test case of each test function in the test function list, synchronously testing the electrical function of the vehicle, and receiving the execution result of each electrical function, so as to generate the functional detection result of the vehicle according to the execution result of each electrical function, realize the efficient and flexible automatic detection of the electronic and electrical functions of the whole vehicle, reduce the labor intensity of the detection personnel, realize the synchronous detection of multiple vehicles, improve the detection efficiency, reduce the number of inspection operators, realize the reliability detection of the electrical functions of the off-line whole vehicle, and improve the quality assurance capability of the manufacturing process. As a result, technical problems in related technologies such as manual inspection taking a long time and difficulty in ensuring the integrity and accuracy of the inspection items, high equipment inspection costs, low operational convenience, poor flexibility, and difficulty in supporting functional reliability inspection are solved.

[0035] Specifically, Figure 1 A schematic flow chart of a method for self-testing the functions of a vehicle when it is off the production line provided in an embodiment of the present application.

[0036] like Figure 1 As shown, the vehicle off-line function self-detection method is applied to the vehicle electrical function detection software, wherein the method includes the following steps:

[0037] In step S101 , a self-test signal of a vehicle is received.

[0038] Understandably, the "rolling off the production line" of a vehicle usually refers to an important stage before a new car is assembled from the production line and is ready to be delivered to dealers or customers. At this stage, the vehicle will undergo a series of functional tests to ensure that it meets factory standards.

[0039] In order to ensure the quality of the vehicle, the embodiment of the present application can perform an electrical function test on the vehicle before the vehicle is offline. In the embodiment of the present application, the self-test of the vehicle electrical function can be achieved through the pre-installed vehicle electrical function test software. Among them, the vehicle electrical function test software can be pre-built by a technician, and the vehicle electrical function test software can include functions such as data reading, system configuration reading, executing original component testing, programming and calibration, result judgment and test result generation.

[0040] For example, the triggering of the self-test signal can be set by a technician on the vehicle side, such as through the vehicle's central control screen, or a collective signal terminal setting for multiple vehicles (for example, connecting to the same local area network or cloud at the same time before the vehicles go offline), so that multiple vehicles can perform vehicle self-tests at the same time.

[0041] The vehicle electrical function detection software pre-installed in the vehicle in the embodiment of the present application can receive the vehicle's self-test signal through the vehicle's internal communication network or internal line to perform subsequent detection.

[0042] It should be noted that in order to avoid communication failures or signal mistransmission, the embodiment of the present application can also initialize the communication network in advance, and initialize each ECU (Electronic Control Unit) inside the vehicle and add it to the vehicle network.

[0043] Optionally, in one embodiment of the present application, before receiving the self-test signal of the vehicle, it also includes: receiving installation instructions from a software installation device; judging whether the vehicle meets preset installation support conditions based on the installation instructions; if the vehicle meets the preset installation support conditions, identifying the sensing signals of the vehicle's diagnostic interface and USB interface; and in response to the sensing signals, controlling the vehicle to install the vehicle electrical function detection software.

[0044] Before receiving the vehicle's self-test signal, the embodiment of the present application first needs to install the vehicle electrical function detection software.

[0045] In some embodiments, the installation method of the embodiment of the present application can be installed by connecting the device: the software installation device is connected to the wheel through the diagnostic interface and the USB interface to realize data transmission, and the software installation instruction is issued; after receiving the installation instruction, the embodiment of the present application can judge the installation support conditions of the vehicle, and when it is determined that the vehicle can be installed with software, determine whether the diagnostic interface and the USB interface are connected, so as to install the whole vehicle electrical function detection software after confirming the connection. Through software installation, the embodiment of the present application can also realize the synchronous detection of multiple vehicles to improve the detection efficiency.

[0046] Furthermore, the preset installation support conditions may include requirements for hardware compatibility, operating system version, network connection, security certification, etc. Among them, hardware compatibility may include: ensuring that the vehicle's ECU or computing platform supports the processor architecture required by the software; the vehicle's hardware meets the software's minimum memory requirements, etc. The operating system version may include: whether the software matches the vehicle's current operating system version, etc. Security certification may include: digital signature verification, etc. Environmental conditions may include: whether there is humidity and electromagnetic interference in the environment, etc.

[0047] In other embodiments, the installation method of the embodiments of the present application can also be to uniformly obtain software installation instructions from a network terminal, and after verifying the installation support conditions, download the vehicle electrical function detection software from the network terminal and install it.

[0048] It should be noted that when the vehicle is installing software, the installation may fail. In this case, you can try a second installation. If the second installation still fails, obtain the reason for the failure and generate an installation failure reminder based on the reason for the failure.

[0049] Optionally, in one embodiment of the present application, controlling the vehicle to install the vehicle electrical function detection software includes: controlling the USB interface to switch modes based on the installation instructions to switch the USB interface to ABD mode, and after the installation of the vehicle electrical function detection software is completed, restoring the USB interface to the initial mode.

[0050] During the actual implementation process, when the embodiment of the present application uses an installation device to install software, the mode of the USB interface can be switched according to the installation instructions to ensure that the software can be smoothly loaded from an external installation device, such as a storage device (such as a USB flash drive) into the vehicle's control system.

[0051] For example, the embodiment of the present application can switch the USB interface to ABD mode, that is, allow the vehicle's ECU or other computing platform to enter a programmable state for software updates or diagnosis. And after the installation is completed, the USB interface is restored to mode. Among them, when entering the Bootloader mode, verification is required to ensure that only authorized devices or tools can perform software updates to prevent unauthorized access or installation of malicious software.

[0052] In step S102, in response to the self-test signal, the vehicle controller configuration code of the vehicle is read to obtain the functional configuration status of the vehicle.

[0053] As a possible implementation method, the embodiment of the present application can read the vehicle's VCU (Vehicle Control Unit) or similar vehicle control module to obtain the vehicle controller configuration code after receiving the self-test signal. The vehicle controller configuration code contains information about the vehicle's functional configuration, such as engine type, emission control system, airbag configuration, etc.

[0054] For example, the embodiment of the present application can use a diagnostic tool or adapter that supports the OBD-II standard to connect to the OBD-II port of the vehicle. Use the diagnostic tool and choose the appropriate communication protocol, select a function on the diagnostic tool to request specific configuration information of the vehicle, such as reading fault codes, freeze frame data, real-time data streams, and even the PID (parameter identifier) ​​of the ECU; the information read by the embodiment of the present application will contain a series of numbers and letters, that is, configuration codes, which represent the status of different systems and components of the vehicle. For example, whether the vehicle is equipped with ABS (anti-lock braking system), EBD (electronic brake force distribution), ESP (body stability program) and other functions; the embodiment of the present application can also interpret these configuration codes according to the manuals or online resources provided by the manufacturer, and record all configuration information for subsequent reference or analysis.

[0055] In step S103, the corresponding test function list and the test case of each test function in the test function list are matched based on the function configuration state, and based on the test function list and the test case of each test function, the electrical functions of the vehicle are synchronously tested, and the execution result of each electrical function is received, so as to generate the function detection result of the vehicle according to the execution result of each electrical function. Among them, the electrical functions include at least one of the rearview mirror folding function, the glass lifting function, the internal and external lighting control function, the air conditioning system function, the seat adjustment function and the electric tailgate function.

[0056] Furthermore, the embodiments of the present application can match the corresponding test function list and the test cases of each test function in the test function list according to the function configuration status.

[0057] The embodiment of the present application can list all available functions based on the configuration information, for example: safety system: ABS, ESP, airbags, etc.; entertainment system: Bluetooth, navigation system, audio system, lighting system, etc.; power system: engine type, gearbox type, etc.

[0058] For each listed function, the embodiment of the present application can create a test function list. The test function list includes basic test items for each function to ensure that it works properly. For example, for the lighting system, the test items may include: light switching when parking, night driving light sensing, high and low light switching, etc.

[0059] The embodiment of the present application can design detailed test cases for each test function. The test case should describe in detail the purpose of the test, test conditions, test steps, expected results, and actual results.

[0060] The embodiment of the present application can perform parallel testing according to the test case and record the actual results. The execution result of each electrical function is received to generate the function detection result of the vehicle according to the execution result of each electrical function.

[0061] Optionally, in one embodiment of the present application, after generating the functional test results of the vehicle, it also includes: generating an electrical function test diagnostic report of the vehicle based on the functional test results; and sending the electrical function test diagnostic report to a preset terminal.

[0062] In some embodiments, the embodiments of the present application can generate an electrical function test diagnostic report for the vehicle based on the function detection results, wherein the generated electrical function test diagnostic report for the vehicle can include the test data of each electrical function and the determination result of whether the function is normal, and the diagnostic report is sent to a preset terminal, such as the cloud, the vehicle manufacturer's maintenance terminal, the vehicle manufacturer's technical terminal, etc., so that technical personnel can perform corresponding maintenance or technical improvements based on the diagnostic report.

[0063] Optionally, in one embodiment of the present application, after performing a vehicle electrical function test on the vehicle based on the electrical function test strategy, it also includes: receiving an uninstall instruction from a software uninstall device; judging whether the vehicle meets a preset uninstall support condition based on the installation instruction; if the vehicle meets the preset uninstall support condition, controlling the vehicle to uninstall the vehicle electrical function test software based on the uninstall instruction, and feeding back the uninstall result to the software uninstall device; otherwise, generating a manual uninstall reminder, and pushing the manual uninstall reminder to a preset terminal.

[0064] In the actual implementation process, the embodiment of the present application can also uninstall the software after completing the whole vehicle electrical function test, connect the software uninstallation device, such as the electrical inspection device, to the whole vehicle OBD interface, start the electrical inspection process, and send the inspection software uninstallation instruction, and after receiving the cockpit controller reply message, confirm that the inspection software has been uninstalled. This ensures that after the vehicle is offline, the electrical function test link will not cause meaningless functions, resources or storage space to be occupied by the vehicle.

[0065] If the preset uninstall support conditions are not met, the embodiment of the present application can perform a manual uninstall reminder and push it to the cloud, the car company's maintenance terminal or the car company's technical terminal so that technical personnel can perform the uninstall process.

[0066] Among them, the preset uninstall support conditions may include whether the complete uninstallation is possible, whether the uninstallation verification is passed, etc., which can be specifically set by those skilled in the art according to actual conditions and are not specifically limited here.

[0067] Combination Figures 2 to 6 As shown, the working principle of the vehicle off-line functional self-detection method of the embodiment of the present application is described in detail by taking an embodiment as an example.

[0068] Combination Figure 2 and Figure 3 As shown, the embodiment of the present application may include the following steps:

[0069] Step S201: Test software installation. At the detection software installation station, the embodiment of the present application can implant the detection software into the vehicle cockpit domain controller through the detection software installation device. For example, the embodiment of the present application can use the PC integrated diagnosis VCI hardware to realize the sending of diagnostic commands and software push.

[0070] When installing the detection software, the vehicle cockpit controller must support USB interface mode switching through diagnostic commands, and the cockpit domain controller must support detection APP push.

[0071] like Figure 3 As shown, the principle of implanting the detection software for test software installation is: the device sends the installation instruction through the OBD interface of the vehicle, sets the USB interface of the vehicle to ADB mode, and implants the detection software into the vehicle cockpit domain controller through the USB interface of the vehicle to complete the software installation, and then sends the installation completion command to restore the USB interface mode.

[0072] The process of testing software installation can be as follows Figure 4 As shown, in the embodiment of the present application, the diagnostic line and USB data line of the detection software installation device can be connected to the OBD diagnostic interface and USB interface of the whole vehicle respectively, and the installation is started. The device automatically sends a USB interface mode switching command to the cockpit domain controller of the whole vehicle through the diagnostic interface, switches the USB interface to ADB mode, and then automatically pushes the detection software package to the cockpit domain controller and automatically completes the installation of the detection software. Finally, the installation completion instruction is sent to make the USB interface of the whole vehicle exit the ADB mode and complete the installation of the detection software.

[0073] Step S202: The test is automatically executed. In the electrical function test station, the embodiment of the present application can open the detection software on the vehicle screen and start the automated test process, the detection process is automatically executed until completion, and the test results of each function can be viewed on the vehicle screen.

[0074] For automatic function detection, all controllers in the vehicle must support the calling of services related to the cockpit controller detection function and the feedback of detection results.

[0075] like Figure 3 As shown, the principle of implementing automatic functional detection is to implant the detection software in the vehicle's cockpit domain controller, stimulate the execution of various electrical functions by calling the functional services defined inside the vehicle, and identify whether the functions are normal by receiving feedback from related ECUs.

[0076] The process of testing automation can be as follows Figure 5As shown, the embodiment of the present application can enter the test software to start the automatic test process based on the instructions issued by the inspection personnel on the vehicle computer screen. The test software automatically identifies the function configuration status of the vehicle under test by reading the vehicle controller configuration code, automatically matches the list of functions under test, and automatically starts the test process. By calling the smart cockpit function service, it drives the execution of various electrical functions of the whole vehicle, detects the function execution status, and synchronously displays the inspection progress and function execution results on the vehicle computer screen. The inspection functions involve various vehicle electrical functions such as rearview mirror folding, glass lifting, internal and external lighting control, air-conditioning system, seat adjustment, electric tailgate, etc., to achieve parallel inspection of multiple functions to improve inspection efficiency. After all test cases are executed, the vehicle computer screen displays the total results and the inspection results of various functions.

[0077] Step S203: Test software uninstallation. At the software uninstallation station, the embodiment of the present application can send an uninstallation instruction to the vehicle through a device to realize automatic uninstallation of the detection software. For example, the embodiment of the present application can use a production line electrical inspection diagnostic instrument to send a software uninstallation diagnostic instruction.

[0078] To uninstall the detection APP, the cockpit domain controller must support automatic uninstallation of the detection APP through diagnostic commands.

[0079] like Figure 3 As shown, the principle of detection software uninstallation is that the electrical inspection equipment sends a detection software uninstallation diagnostic command to the vehicle cockpit domain controller through the vehicle OBD interface. The vehicle cockpit executes the detection software uninstallation operation and replies the execution status to the equipment.

[0080] The process of testing software uninstallation can be as follows Figure 6 As shown, the operator can connect the software uninstallation device, such as the electrical inspection equipment, to the OBD interface of the vehicle, start the electrical inspection process, send the inspection software uninstallation instruction, and after receiving the reply message from the cockpit controller, confirm that the inspection software has been uninstalled.

[0081] According to the functional self-test method for the whole vehicle off-line proposed in the embodiment of the present application, it is possible to respond to the self-test signal of the vehicle, read the vehicle controller configuration code of the vehicle, so as to obtain the functional configuration status of the vehicle, thereby combining the test function list matched by the functional configuration status and the test case of each test function in the test function list, synchronously test the electrical functions of the vehicle, and receive the execution result of each electrical function, so as to generate the functional test result of the vehicle according to the execution result of each electrical function, realize efficient and flexible automatic detection of the electronic and electrical functions of the whole vehicle, reduce the labor intensity of the inspection personnel, realize simultaneous detection of multiple vehicles, improve the detection efficiency, reduce the number of inspection operators, realize the reliability detection of the electrical functions of the whole vehicle off-line, and improve the quality assurance capability of the manufacturing process. Thus, the technical problems in the related technology that manual detection is time-consuming and difficult to ensure the integrity and accuracy of the detection items, the equipment detection cost is high, the operation convenience is low, and the flexibility is poor, and it is difficult to support the functional reliability detection are solved.
