[0029] Please refer toFigure 1 , Figure 1 A method for locating an abnormality in a vehicle central control screen display provided in an embodiment of the present invention includes steps S100 to S300.

[0030] Step S100, obtaining the designated button signal pressed by the user in response to the abnormal screen display on the central control screen of the vehicle within a preset time. In order to accurately locate the problem of abnormal screen display, the present invention requires the user to press the designated button within a preset time when the screen display abnormality occurs on the central control screen of the vehicle, so that when the signal is obtained, the positioning method of the present invention can be started. The screen display abnormality can be, for example, a black screen, a blue screen, a display error, etc.

[0031] In a specific embodiment of the present invention, the preset time is a pre-set value, and its value range is 1 to 20 seconds, which can be set as needed. This time will affect the effective time of locating the problem of abnormal screen display. For example, if the preset time is set to 10 seconds, when the specified key signal is obtained, it means that the central control screen of the vehicle has a screen display abnormality problem within 10 seconds, and the subsequent analysis is also mainly based on the data within these 10 seconds.

[0032] In a specific embodiment of the present invention, the designated key signal is a plurality of key combination signals defined in a sequential order. The designated key signal should not conflict with other operation keys as much as possible, and can be set to a key combination of a larger number as much as possible. For example, the designated key signal can be set to: press the custom key 3 times, and then press the square control volume key 3 times. After such setting, if the user's central control screen displays an abnormality during the use of the vehicle (for example, during driving), these keys can be pressed within 10 seconds. After obtaining the user's pressing of the designated key signal, the subsequent steps S200 and S300 can be executed.

[0033] In this step, the central control screen is generally the display screen of the central control system, which is generally independent of the vehicle system and can realize many functions such as navigation, audio and video playback, vehicle control, etc. Common central control systems are mostly Android systems, Hongmeng systems, or iOS systems, etc. In some of the following embodiments, the Android system is used as an example for description.

[0034] Step S200: According to the designated key signal, designated data of the central control system of the vehicle is obtained according to the first preset rule.

[0035] See also Figure 2, in a specific embodiment of the present invention, step S200 includes: S211. When a specified key signal is received, set the attribute value of the first attribute to a preset value; S212. When it is monitored that the attribute value of the first attribute is the preset value, obtain the specified data of the central control system according to the first preset rule. In this embodiment, the reason for introducing the first attribute is to separately set the key operation and the monitoring system. The advantages of doing so are as follows: First, the key operations in the vehicle system are usually processed by the hardware layer, while the monitoring system belongs to the software layer. Since the hardware and software belong to different system modules, directly monitoring the keys requires cross-module communication, increasing complexity and latency; Second, directly allowing the monitoring system to monitor the keys may introduce security risks. By setting the first attribute as an intermediate step, it can be ensured that the monitoring system is only started when needed, improving the stability and security of the system; Third, the separate setting conforms to the modular design principle, facilitating system maintenance and upgrade. In specific implementation, when a specified key signal is received, vendor.log.log_dump_cur_info (i.e., the first attribute) is set to 1, and when this value is monitored to be 1, the specified data is obtained.

[0036] Please refer to Figure 3 , in a specific embodiment of the present invention, obtaining the specified data of the central control system of the vehicle according to the first preset rule includes steps S221 to S225.

[0037] Step S221. Obtain the screenshot content of the central control screen. The screenshot content of the central control screen is crucial for the subsequent analysis of screen display abnormal problems. Therefore, in this step, it is necessary to first obtain the screenshot content of the central control screen.

[0038] Step S222. Obtain the memory information, CPU information, and input / output (I / O) information of the central control system according to Rule 1. Rule 1 is a sub-rule of the first preset rule, and Rule 1 can be understood as the code command for specifically obtaining information. Taking the Android system as an example, Rule 1 corresponds to the following code, and the specified information of the central control system can be obtained through these commands.

[0039] cat / proc / meminfo > ${root_path}procmeminfo.txt; This command grabs the memory usage of the system, including information such as total memory, free memory, cache, and swap space.

[0040] cat / proc / vmstat > ${root_path}vmstat.txt; This command grabs the statistical information of virtual memory, including paging, swapping, memory allocation, etc.

[0041] cat / proc / pressure / io > ${root_path}pressureio.txt; This command captures I / O pressure information and reflects the load of the system on I / O operations.

[0042] cat / proc / pressure / memory > ${root_path}pressurememory.txt; This command captures memory pressure information and reflects the load of the system on memory allocation.

[0043] cat / proc / pressure / cpu > ${root_path}pressurecpu.txt; This command captures CPU pressure information and reflects the load of the system on CPU resources.

[0044] The above information can help analyze the performance bottlenecks of the system, such as problems like insufficient memory, excessive I / O load, or tight CPU resources.

[0045] Step S223, obtain the Bugreport stack information of the central control system according to Rule 2. Bugreport stack information is an important tool for debugging and problem troubleshooting. It provides the detailed status and error context during program operation, helping developers efficiently locate and solve problems. For example, the Bugreport stack information can be obtained through the following code.

[0046] logi "bugreport start..."

[0047] bugreport_result=$( / system / bin / bugreportz)

[0048] bugreport_path=$(echo $bugreport_result | sed's / ^OK: / / ')

[0049] sync

[0050] cp $bugreport_path ${root_path} / bugreport.zip.

[0051] This code is used to generate the BugReport of the Android system, which is a compressed package containing device logs, stack traces, and other diagnostic information.

[0052] Step S224: Obtain the information related to Surface, memory information (meminfo), Activity, Window, Display, and Input of the central control system according to Rule 3. Specifically, in implementation, the relevant information can be obtained through the Android system command dumpsys.

[0053] Among this information, Surface is a low-level object for graphics rendering in Android, usually associated with Window and View. This part of the information can help analyze graphics rendering performance or problems; memory-related information includes detailed information on memory usage, including memory allocation for each process, heap memory, shared memory, etc.; Activity-related information includes the lifecycle state of Activity, task stack, launch mode, etc., which helps analyze the behavior of Activity or troubleshoot related problems; window-related information includes the layout, hierarchy, focus state, etc. of the window. The window is the container of Activity and manages the display and interaction of views; display-related information includes screen resolution, density, current display mode, etc.; input-related information includes touch events, key events, input method state, etc., which helps analyze user interaction or input-related problems.

[0054] In a specific embodiment of the present invention, for example, the above relevant information can be obtained through the following code:

[0055] / system / bin / dumpsysSurfaceFlinger>${root_path}surfaceglinger.txt2>&1

[0056] / system / bin / dumpsysmeminfo>${root_path}meminfo.txt

[0057] / system / bin / dumpsys activity a>${root_path}activity.txt

[0058] / system / bin / dumpsys window w>${root_path}window.txt

[0059] / system / bin / dumpsys display>${root_path}display.txt

[0060] / system / bin / dumpsys input>${root_path}input.txt.

[0061] Step S225: Obtain the runtime performance data of the application programs and system components of the central control system according to Rule 4. For example, these data can be captured through atrace, and the specific code is as follows.

[0062] / system / bin / atrace -o / data / atrace-traces / trace_curinfo.atrace-trace -t 10s -b 200mb sched freq idle am wmgfx view binder_driverhaldalvik camera input res. This code is used to call the atrace tool in the Android system to capture performance data, specify the path and name of the output file, and the generated trace data will be saved to the / data / atrace-traces / trace_curinfo.atrace-trace file. Set the trace duration to 10 seconds, set the size of the trace buffer to 200MB for storing trace data, and specify the event categories to be traced, including: CPU scheduling information (sched), CPU frequency adjustment information (freq), CPU idle status information (idle), Activity Manager information (am), window manager and graphics rendering information (wmgfx), view layout and drawing information (view), Binder driver and Dalvik virtual machine information (binder_driverhaldalvik), camera operation information (camera), user input (such as touch, key) information (input), and resource management information (res).

[0063] cp / data / atrace-traces / trace_curinfo.atrace-trace

[0064] ${root_path}trace_curinfo.atrace-trace. This code is to copy the generated trace file from / data / atrace-traces / trace_curinfo.atrace-trace to

[0065] the ${root_path}trace_curinfo.atrace-trace path, where ${root_path} is a variable representing the prefix of the target path.

[0066] Through the above steps, you can get enough data and save them all in a folder. For example, you can get the following files: XXX.png (screenshot), activity.txt, bugreport.zip, display.txt, input.txt, meminfo.txt, procmeminfo.txt, surfaceglinger.txt, trace_curinfo.atrace-trace, wmstat.txt, window.txt; in addition, you can also get other data information related to screen display abnormalities according to other rules.

[0067] Step S300: According to the specified data, locate the cause of the abnormal screen display of the central control system according to the second preset rule. After enough data is obtained according to step S200, the cause of the abnormal screen display can be analyzed based on these data.

[0068] See also Figure 4 In a specific embodiment of the present invention, step S300 includes steps S311 to S313.

[0069] Step S311, based on the memory information, determine whether there is a memory leak: if so, locate the process that occupies the largest memory. If some processes are abnormal, the excessive memory occupation will lead to memory leaks, resulting in abnormal screen display. Therefore, the abnormal program can be located based on the memory information. For example, through meminfo, it is seen that the memory of a process is increasing in large quantities until the system memory is leaked. Then the system will have low memory, which will lead to various binder communication anomalies, and further the system will freeze and the screen display will be abnormal. It can be determined that this process caused the screen display abnormality.

[0070] Step S312: According to the CPU information, determine whether the CPU resources are exhausted: if so, locate the process that consumes the most CPU resources. Similarly, the CPU resources of the central control system are also limited. If the CPU resources are exhausted, the screen display will be abnormal. Therefore, the process that consumes a lot of CPU resources can be located according to the CPU information.

[0071] Step S313: According to the input / output information, determine whether there is IO blocking: if yes, locate the process with the largest disk usage. In step S200, the input / output (IO) information is obtained, through which it can be seen which process is constantly reading and writing, causing the system IO blocking and causing system abnormality.

[0072] In a specific embodiment of the present invention, step S300 includes: determining whether the screenshot content is abnormal: if so, locating the problem process according to the information related to Surface, Activity, and the window; if not, performing board support package (BSP) driver analysis and QNX operating system virtualization analysis. In this step, if the screenshot content is normal and consistent with the displayed content, it indicates that the data given by the Android application layer is correct, and there is no problem passing through the window display layer and then being synthesized by SurfaceFlinger. At this time, if a screen display abnormality occurs on-site, then board support package (BSP) driver analysis and QNX operating system virtualization analysis are required.

[0073] The BSP is a software support package provided for a specific hardware platform (such as a development board or an embedded device), mainly used for the interaction between the operating system and the hardware. In the Android system, the BSP is the bridge connecting the Android framework and the underlying hardware. In the above embodiment, the screen display abnormality may be caused by an underlying hardware or driver abnormality. Therefore, it is necessary to analyze whether there are problems in the relevant modules of the BSP (such as display drivers, power management, etc.).

[0074] In the above embodiment, if the screenshot content is abnormal (for example, black), then it is necessary to locate the problem process according to the information related to Surface, Activity, and the window. Specifically, if the information of dump activity windowdisplay surfaceflinger shows that the active activity and the focused window have the same package name, and the information in the SurfaceFlinger layer is also the same layer, and at this time the data given by this process is abnormal, then the data given by this process itself is problematic. For example, abnormal projection data of Carplay causes the CSD screen to go black.

[0075] Please refer to Figure 5 , in a specific embodiment of the present invention, step S300 further includes step S321 and step S322.

[0076] Step S321: Based on the Bugreport stack information, determine whether the reason for the abnormal screen display is caused by an abnormality in the central control system. If so, locate the abnormal program in the central control system. Analyze the current background services, active processes, system exceptions, and system crashes through the Bugreport information. For example, if the core service crashes or the core process experiences an ANR (Application Not Responding), which causes the heartbeat not to be sent to QNX, and restarting Android results in a black screen, the cause of the problem can also be confirmed. ANR is a common abnormal phenomenon in the Android system, usually occurring when the main thread of an application is blocked and unable to respond to user operations or system events in a timely manner.

[0077] Step S322: Based on the runtime performance data of the application and system components, determine whether the display delivery process is normal. If so, perform board support package driver analysis and QNX operating system virtualization analysis. Through trace_curinfo.atrace - trace, it is possible to see which process is currently delivering the display from Android to virtualization, and at the same time, it is also possible to see the series of processes from the application data being drawn to the system being synthesized and finally delivered to the BSP for display. If there is a display delivery process, then underlying BSP and virtualization analysis are required. If there is no display delivery process, then Android analysis is required.

[0078] It should be noted that the step division of the above various methods is only for clear description. During implementation, they can be combined into one step or some steps can be split into multiple steps. As long as the same logical relationship is included, they are all within the protection scope of this application. Making insignificant modifications to the algorithm or process or introducing insignificant designs, but without changing the core design of the algorithm and process, are all within the protection scope of this patent.
