[0002] The dual-system architecture of the vehicle system refers to the setting of two operating systems in the vehicle system, such as the QNX system and the Android system. Each operating system is equipped with multiple vehicle applications. For example, the Android system is equipped with vehicle settings, Bluetooth phone, multimedia, driving recorder, 360-degree surround view, air conditioning settings, voice, virtual image and other applications. When the vehicle application is running, it will occupy the memory resources of the operating system.

[0034] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0036] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0037] Combine the following Figures 1 to 6 , the operating system memory monitoring method, vehicle-mounted system, vehicle and storage medium provided by the present invention are explained.

[0038] See also Figure 1 , Figure 1 A flowchart of a method for monitoring operating system memory provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the method includes:

[0039] S110: Reading a preset target value configuration file to obtain a target value of memory usage of the vehicle-mounted application in the operating system.

[0040] It should be noted that the operating system in this embodiment is the Android system, which belongs to the vehicle-mounted system, and the vehicle-mounted system also includes the QNX system (a real-time operating system based on a microkernel architecture). The QNX system is the main system, which is mainly responsible for functions such as instrument applications, including applications such as instrument HMI (human-machine interface) applications, boot animation applications, and 360 panoramic image applications. The Android system is the secondary system, which is mainly responsible for functions such as central control entertainment information applications, including applications such as vehicle settings, Bluetooth phones, multimedia, driving recorders, air conditioning settings, voice, and virtual images. By pre-setting the target value configuration file and burning the target value configuration file to the target disk of the vehicle-mounted system, it is easy to read the target value of the memory usage of the vehicle-mounted application, thereby facilitating subsequent memory usage comparisons.

[0041] S120: Obtain actual memory usage values ​​of vehicle-mounted applications in the operating system.

[0042] It should be noted that the actual memory usage value of one or more vehicle-mounted applications may be obtained in the above step S120, that is, the actual memory usage value of a specified vehicle-mounted application may be obtained, and the specified vehicle-mounted application may be one or more, or the actual memory usage value of all vehicle-mounted applications in the operating system may be obtained. In order to better monitor the memory usage of each vehicle-mounted application in the operating system, in this embodiment, the actual memory usage value of all vehicle-mounted applications in the operating system is obtained, and subsequent comparison and monitoring are performed.

[0043] S130: Determine whether the memory usage of the vehicle-mounted application exceeds the limit or is normal by comparing the actual memory usage value with the corresponding memory usage target value.

[0044] S140: If it is determined that the memory usage of the vehicle-mounted application exceeds the limit, the memory usage exceeding limit information is displayed and a screenshot of the display interface is taken. The memory usage exceeding limit information includes the application package name of the vehicle-mounted application that exceeds the memory usage limit, the actual memory usage value, and the memory usage target value.

[0045] It should be noted that, through the above steps, the real-time monitoring of the memory usage of each vehicle-mounted application in the operating system can be well achieved, so that relevant personnel can handle the memory excess situation in a timely manner, such as reporting bugs (defects), etc. The display method of the memory excess information can be a green screen with red text, etc., which is convenient for relevant personnel to identify.

[0046] In some embodiments, the step of reading a preset target value configuration file is performed on the premise of determining that a memory monitoring function is turned on; wherein a pre-registered listener is used to monitor the on / off status of the memory monitoring function.

[0047] In some embodiments, the step of obtaining the on / off state of the memory monitoring function includes:

[0048] 1. When it is determined that the operating system has been started, a pre-registered listener is used to monitor the attribute value of the memory monitoring switch, the memory monitoring switch is a preset system attribute, and the attribute value of the memory monitoring switch changes with the on / off state of the memory monitoring switch, and the on / off state of the memory monitoring switch is set by the user.

[0049] It should be noted that the operating system in this embodiment is the Android system. After the Android system is started, the AMS (Activity Manager Service) service of the Android system is started, and the operating system memory monitoring device built into the AMS service (the device for running the operating system memory monitoring method) is started. In order to determine whether memory monitoring is required, the operating system memory monitoring device needs to obtain the on / off status of the memory monitoring function, so that when it is determined that the memory monitoring function is turned on, subsequent file reading and obtaining the actual memory usage value of the vehicle-mounted application and other operations are performed. This step improves the controllability of the entire dual-system memory monitoring method.

[0050] Specifically, a user (tester or developer, etc.) can turn on or off the memory monitoring switch in the engineering mode application of the operating system (Android system). When the user turns on the memory monitoring switch, the engineering mode application sets the attribute value of the memory monitoring switch to a preset first attribute value. Conversely, when the user turns off the memory monitoring switch, the engineering mode application sets the attribute value of the memory monitoring switch to a preset second attribute value. The first attribute value is different from the second attribute value.

[0051] 2. If it is detected that the attribute value of the memory monitoring switch is a preset first attribute value, it is determined that the memory monitoring function has been turned on.

[0052] 3. If it is detected that the attribute value of the memory monitoring switch is a preset second attribute value, it is determined that the memory monitoring function is turned off.

[0053] It should be noted that the first attribute value may be True, etc., and the second attribute value may be False, etc.

[0054] In addition to using a listener to monitor the attribute value of the memory monitoring switch when determining that the operating system is started, in some embodiments, the following is also included:

[0055] 1. Using the monitor, monitor the change of the attribute value of the memory monitoring switch.

[0056] 2. If it is monitored that the attribute value of the memory monitoring switch changes from the first attribute value to the second attribute value, the memory monitoring function is turned off.

[0057] 3. If it is monitored that the attribute value of the memory monitoring switch changes from the second attribute value to the first attribute value, the memory monitoring function is turned on.

[0058] It should be noted that by using a listener to monitor changes in the attribute value of the memory monitoring switch, the memory monitoring function can be turned on and off at any time.

[0059] In some embodiments, the step of obtaining the target value of memory usage of the vehicle-mounted application in the operating system by reading a preset target value configuration file includes:

[0060] The target value configuration file pre-burned to the designated directory of the target disk is read to obtain the structure data.

[0061] The structural data includes: an application package name and a target memory occupancy value, the application package name and the target memory occupancy value correspond one to one, and the application package name is a unique identifier of the vehicle-mounted application.

[0062] It should be noted that by parsing the target value configuration file into the above structured data, it is possible to directly obtain the memory usage target value of the corresponding application package name and perform targeted comparison in the subsequent comparison process.

[0063] It should also be noted that the target value configuration file is pre-configured with information such as the application package name, the memory usage target value, and the system to which the application belongs. The memory usage target value corresponding to each application package name in the target value configuration file is a preset empirical value, such as the memory usage target value of the Android system navigation application (application package name com.android.navi) is 500MB (megabytes), and the memory target value of the Android system vehicle setting application (application package name com.android.carsettig) is set to 300MB.

[0064] It should be mentioned that by setting the corresponding memory usage target value for the vehicle-mounted application in the target value configuration file, the upper limit of the memory usage of each vehicle-mounted application can be clearly defined, thereby facilitating subsequent memory monitoring.

[0065] Figure 2 This is a flow chart of presetting a target value configuration file (pre-burning the target value configuration file to a specified directory of the target disk) in the operating system memory monitoring method provided in one embodiment of the present invention. Please refer to Figure 2First, write the target value configuration file in the system (Android system) source code. Secondly, use the preset compilation tools, such as Jenkins (an open source automation server), etc. to compile and package the system source code. The compiled product is the system flashing package. Burn the system flashing package to the specified directory of the target disk of the vehicle system to complete the preset target value configuration file. By burning the target value configuration file to the specified directory of the above-mentioned target disk, it is possible to facilitate subsequent file reading and improve file reading efficiency. It should be mentioned that the system source code also includes product.mk (product build configuration file) and the like.

[0066] In some embodiments, the step of obtaining the actual memory usage value of the vehicle-mounted application in the operating system includes: regularly obtaining the actual memory usage value of the vehicle-mounted application in the operating system according to a target monitoring frequency, wherein the step of determining the target monitoring frequency includes:

[0067] 1. Obtain the CPU usage of the system recycling thread (kswapd) preset in the operating system and the remaining memory capacity of the operating system.

[0068] 2. If the CPU usage is less than a preset usage threshold, and the remaining memory capacity is greater than a preset memory capacity threshold, the target monitoring frequency is determined to be a first preset frequency.

[0069] 3. If the CPU usage is greater than the usage threshold, and the remaining memory capacity is greater than the memory capacity threshold, the target monitoring frequency is determined to be a second preset frequency.

[0070] 4. If the CPU usage is less than the usage threshold, and the remaining memory capacity is less than the memory capacity threshold, the target monitoring frequency is determined to be a third preset frequency.

[0071] 5. If the CPU usage is greater than the usage threshold and the remaining memory capacity is less than the memory capacity threshold, the target monitoring frequency is determined to be a fourth preset frequency, the first preset frequency, the second preset frequency, and the third preset frequency increase sequentially, and the fourth preset frequency is greater than or equal to the third preset frequency.

[0072] It should be noted that if the CPU usage of the system recovery thread is greater than the usage threshold, and / or the remaining memory capacity of the operating system (Android system) is less than the memory capacity threshold, it means that the operating system is short of memory at this time. Therefore, in the above embodiment, different target monitoring frequencies are set according to the different values ​​of these two information to ensure timely and effective monitoring of the operating system's memory exceeding the standard when the operating system is short of memory, so as to facilitate subsequent data analysis by relevant personnel.

[0073] It should also be noted that the usage rate threshold and the memory capacity threshold can be set according to actual conditions, such as the usage rate threshold is 20%, 21%, and the memory capacity threshold is 320MB, 330MB, etc. The first preset frequency can be 30 seconds / time, etc., the second preset frequency can be 10 seconds / time, the third preset frequency can be 5 seconds / time, etc., and the fourth preset frequency can be 5 seconds / time, etc. It is only necessary to ensure that the first preset frequency, the second preset frequency, and the third preset frequency increase in sequence, and the fourth preset frequency is greater than or equal to the third preset frequency.

[0074] In some embodiments, the step of obtaining the actual memory usage value of the in-vehicle application in the operating system includes:

[0075] 1. Send a memory information dump command (dumpsysmeminfo command) to the service manager preset in the operating system, wherein the memory information dump command is used to instruct the service manager to obtain the memory usage information of the application process in the operating system and feedback it, wherein the memory usage information includes the application package name of the application process and the process memory usage value.

[0076] It should be noted that the memory usage information corresponds one-to-one to the application process in the operating system.

[0077] 2. Determine the in-vehicle application to which the process memory occupancy value belongs according to the application package name in the memory occupancy information, and determine the process memory occupancy value as the actual memory occupancy value of the corresponding in-vehicle application.

[0078] It should be noted that, since the applications in the vehicle system are basically single-process applications, the memory monitoring requirements of the vehicle system can be better met by executing the above steps.

[0079] Specifically, if the application package names of all the memory usage information are different, it means that the vehicle-mounted applications of the operating system are all single-process applications, so the process memory usage value in the memory usage information is directly determined as the actual memory usage value of the corresponding vehicle-mounted application.

[0080] In some embodiments, the step of obtaining the actual memory usage value of the in-vehicle application in the operating system further includes:

[0081] If there is memory usage information carrying the same application package name, the process memory usage values ​​in the memory usage information carrying the same application package name are summed to obtain the actual memory usage value of the in-vehicle application corresponding to the current application package name.

[0082] It can be understood that, by traversing the application package names, if the same application package name exists, the process memory occupancy values ​​with the same application package name are summed to obtain the actual memory occupancy value of the vehicle-mounted application corresponding to the current application package name; the remaining process memory occupancy values ​​are determined as the target memory occupancy values, and according to the application package name corresponding to the target memory occupancy value, the vehicle-mounted application to which the target memory occupancy value belongs is determined, and the target memory occupancy value is determined as the actual memory occupancy value of the corresponding vehicle-mounted application.

[0083] In the above embodiment, if the application package name in the memory occupancy information is the same, it means that the application corresponding to the application package name is a multi-process application. Therefore, the process memory occupancy values ​​with the same application package name are summed to obtain the actual memory occupancy value of the vehicle-mounted application corresponding to the current application package name. The vehicle-mounted application corresponding to the remaining memory occupancy information is a single-process application. Therefore, the process memory occupancy value in the remaining memory occupancy information is the actual memory occupancy value of the corresponding vehicle-mounted application. It can be understood that if there are multi-process applications in the vehicle-mounted system, by executing the above steps, the actual memory occupancy value of the multi-process application can also be obtained, thereby realizing memory occupancy monitoring.

[0084] In some embodiments, the step of comparing the actual memory usage value with the corresponding memory usage target value to determine whether the memory usage of the vehicle application exceeds the standard or is normal includes:

[0085] 1. If the actual memory usage value exceeds the corresponding memory usage target value, it is determined that the memory usage of the current in-vehicle application exceeds the target value.

[0086] 2. If the actual memory usage value is less than or equal to the memory usage target value, it is determined that the current memory usage of the in-vehicle application is normal.

[0087] It should be noted that, through the above steps, it is possible to better monitor the memory exceeding the limit of vehicle-mounted applications.

[0088] In some embodiments, it also includes:

[0089] According to a preset event sending frequency, Monkey events are regularly sent to the operating system, wherein the Monkey events are randomly generated user input events, and the user input events are used to perform random operations on the interface of the vehicle-mounted application.

[0090] It should be noted that the event sending frequency can be set according to actual conditions, such as 500 milliseconds / time. User input events include random clicks, slides, scrolls, long presses, and text input. By regularly sending Monkey events to the operating system, it is possible to simulate real events, thereby fully covering the operating logic of each vehicle-mounted application, fully exposing the memory usage of each vehicle-mounted application, and facilitating early monitoring of the memory usage problem of the vehicle-mounted application, so as to deal with it as soon as possible.

[0091] In some embodiments, it also includes:

[0092] 1. Obtain the remaining memory capacity of the operating system.

[0093] 2. If the remaining memory capacity is less than the preset capacity threshold and the memory usage of all vehicle-mounted applications is normal, the system memory information is displayed and a screenshot of the display interface is taken. The system memory information includes: the remaining memory capacity and the memory information of each vehicle-mounted application. The memory information includes the application package name and the actual memory usage value.

[0094] It should be noted that the capacity threshold can be set according to actual conditions, such as 320MB (megabytes), etc. Through the above steps, real-time monitoring of the remaining memory status of the operating system can be achieved.

[0095] 3. If the remaining memory capacity is less than the capacity threshold and the memory usage of the in-vehicle application exceeds the limit, the remaining content capacity and the memory excess information are displayed, and a screenshot of the display interface is taken.

[0096] It should be noted that in order to avoid the relevant personnel from failing to obtain the corresponding information in a timely manner due to the rapid changes in the memory over-standard information displayed in the over-standard display interface, when it is determined that the over-standard display interface pops up on the display screen, or the display data in the over-standard display interface changes, a screenshot of the over-standard display interface is taken and the screenshot image is saved to the target directory of the target disk, which can facilitate subsequent relevant personnel to identify and handle the over-standard situation.

[0097] It should be mentioned that the naming format of the screenshot image can be set according to actual conditions, such as the current time.

[0098] The following is a specific example to explain the operating system memory monitoring method in the above embodiment. Figure 3 , S310: Start the Android system and QNX system.

[0099] S320: Determine whether the memory monitoring function of the Android system is turned on.

[0100] S330: When it is determined that the memory monitoring function is turned on, a preset target value configuration file is read to obtain a target value of memory usage of the vehicle-mounted application in the operating system; and an actual memory usage value of the vehicle-mounted application in the operating system is obtained.

[0101] S340: Compare the actual memory usage value with the corresponding memory usage target value to determine whether the memory usage of the vehicle-mounted application exceeds the limit or is normal, display the memory excess information, and take a screenshot of the display interface.
