[0087] In step S104, the tire pressure, vehicle speed, fuel consumption and driving distance are displayed on the car machine interface of the automotive system in response to a first instruction.

[0088] Specifically, the first instruction is used to display the car machine interface, and is triggered when the car machine interface is opened or refreshed.

[0089] In some embodiments, the parsed tire pressure, vehicle speed, fuel consumption and driving distance are obtained, and the tire pressure, vehicle speed, fuel consumption and driving distance are displayed on the car machine interface of the automotive system.

[0167] In step S401 of some embodiments, the function modules in the design graph are mapped to the data packets in the Ethernet communication (a dictionary is created by mapping each signal to a value as a key through a dictionary), ensuring complete coverage of the test.

[0168] Step S402, obtaining the design graph.

[0169] Exemplarily, the design graph schematic diagram is shown in FIG. 5, wherein the design graph schematic diagram includes a tire pressure, vehicle speed, fuel consumption and driving distance chart.

[0170] Step S403, generating a simulation data packet according to the preset mapping relationship and the function modules in the design graph.

[0171] Exemplarily, the preset mapping relationship diagram is shown in FIG. 6. The tire pressure information prompt includes display or alarm work instructions, and the tire pressure information prompt includes HMIVw_NotifyOnChgFLTireSt, HMIVw_NotifyOnChgFRTireSt, HMIVw_NotifyOnchgRLTireSt, HMIVw_NotifyOnChgRRTireSt and HMIVw_NotifyonchgTireWarningSt. Specifically, HMIVw_NotifyOnChgFLTireSt represents "left front tire pressure change". When the air pressure of the left front tire changes, the system updates this state and may trigger a warning; HMIVw_NotifyOnChgFRTireSt represents "right front tire pressure change". When the air pressure of the right front tire changes, the system updates this state and may trigger a warning. HMIVw_NotifyOnchgRLTireSt represents "left rear tire pressure change". When the air pressure of the left rear tire changes, the system updates this state and may trigger a warning. HMIVw_NotifyOnChgRRTireSt represents "right rear tire pressure change". When the air pressure of the right rear tire changes, the system updates this state and may trigger a warning. HMIVw_NotifyonchgTireWarningSt represents "tire warning state notification". When the air pressure of any tire exceeds the preset safety range, the system updates HMIVw_NotifyonchgTireWarningSt.

[0172] In step S404 of some embodiments, the simulation data packet is sent using the Ethernet communication module to simulate changes in vehicle status, and the simulation data packet includes tire pressure, vehicle speed, fuel consumption, driving distance, etc.

[0173] In step S404 of some embodiments, the simulation data packet is sent using the Ethernet communication module to simulate changes in vehicle status, and the simulation data packet includes tire pressure, vehicle speed, fuel consumption, driving distance, etc.

[0174] In step S405 of some embodiments, the automobile system starts the automobile HMI interface and sets the program to monitor the Ethernet receiving state of the automobile system.

[0175] In step S405 of some embodiments, the automobile system starts the automobile HMI interface and sets the program to monitor the Ethernet receiving state of the automobile system.

[0176] The automobile system subscribes through a service signal, and after subscription, the underlying system transmits signals to the instrument application. After the instrument application receives the signals, it displays the corresponding functions.

[0177] It can be understood that the Ethernet signal is successfully received, and the function can be implemented, if not, the function is not displayed, at this time, the problem in implementation can be judged, and the instrument application judges the fault reason.

[0178] In step S406, in response to the first instruction, the tire pressure, vehicle speed, fuel consumption and driving distance are displayed on the car machine interface of the automobile system.

[0179] In step S407, the car machine interface is screenshot to obtain a target image.

[0180] In step S407 of some embodiments, the car machine interface is screenshot to capture the currently displayed content. Among them, each signal has a corresponding function, and also has a corresponding slice, and the application displays the slice to the screen end. Illustratively, the target image schematic diagram is shown in FIG. 7, wherein the target image schematic diagram includes tire pressure, vehicle speed, fuel consumption, and driving distance chart.

[0181] Illustratively, the code of the embodiment is as follows:

[0182] In step S408, the first key feature is extracted from the design image and the second key feature is extracted from the target image, and the difference degree is obtained by comparing the first key feature with the second key feature.

[0183] In step S408 of some embodiments, the first key feature and the second key feature are extracted from the image, such as pixel value, color, texture, shape, etc.

[0184] Specifically, image difference analysis can be performed in the following way to obtain the difference degree:

[0185] Pixel-by-pixel difference: Calculate the difference value of each pixel in adjacent frames. The difference between pixel values (such as absolute value difference or squared difference) can be used to represent the degree of difference between frames. Larger difference values may indicate the presence of errors or abnormal conditions.

[0186] Block matching: Divide the image into multiple blocks and compare the pixel differences between corresponding blocks in adjacent frames. Block matching algorithms can calculate similarity measures between blocks based on pixel differences, such as mean squared error, cross-correlation, etc. Inconsistent or abnormal block matching results may indicate the presence of slice errors.

[0187] Correlation comparison: Evaluate the similarity between adjacent frames by calculating their correlation. Correlation measures can be achieved by calculating the correlation coefficient or similarity index (such as structural similarity index) between the pixels of the two frames. Low correlation or similarity index may indicate the presence of slice errors or discontinuity in image content.

[0188] Optionally, key components in the target image and the design image are determined, such as buttons, text boxes, icons, etc. The positions, sizes, shapes, styles, and relative relationships of the key components in the images are compared to obtain the difference degree. Exemplarily, a schematic diagram of key components in the target image is shown in FIG. 8.

[0189] Further, by comparing the features of the design image and the target image, the similarity or difference degree between them is calculated.

[0190] In step S409, a preset threshold is obtained, and it is determined whether the difference degree exceeds the preset threshold.

[0191] In step S410, it is determined that the interface is displayed incorrectly.

[0192] In step S410 of some embodiments, it is determined that the interface is displayed incorrectly, and the test result is a test failure.

[0193] In step S411, a target model is obtained, and the design image and the target image are analyzed by the target model to obtain the test failure reason.

[0194] In step S412, the test result is recorded.

[0195] In step S412 of some embodiments, the result of each test is recorded, including passing and failing cases, and specific reasons for failure.

[0196] Further, the failed test is analyzed in depth to find the root cause, and the test process is repaired and optimized in time.

[0197] Optionally, according to the test result and feedback, the test process and method are continuously optimized to improve the test efficiency and quality. The design image and signal mapping are continuously updated to adapt to the changes and development of the automotive HMI interface.

[0198] In step S413, in response to a third instruction, the target image, the design image, the test result, the difference degree, and the test failure reason are displayed on a test result page of the automotive system.

[0199] In step S414, it is determined that the interface is displayed correctly.

[0200] In step S414 of some embodiments, it is determined that the interface is displayed correctly, and the test result is a test success.

[0201] In step S415, the test result is recorded.

[0202] In step S416, in response to a second instruction, the target image, the design image, the test result, and the difference degree are displayed on a test result page of the automotive system.
