The inventor has appreciated that as the information and entertainment functions of in-vehicle entertainment systems have increased, network security incidents have increased. The host system on the vehicle has a plurality of functional modules to be detected, so that the running period of the existing host detection is very long, the running time of the vehicle is not fixed, when the running time of the host system of the vehicle is short, the host detection may not be finished, and the detection will be started from the beginning next time after the host system of the vehicle is started, so that the repeated detection from the beginning can cause the problem of missed detection.

Based on the above situation, the present application provides a host system detection method, which detects, in a periodic detection manner, that a detection period does not end due to the shutdown of the host system, but continues the unfinished period again when the host system is started next time. The host system detection method provided by the present application is described below by some embodiments.

To facilitate understanding of the present embodiment, a detailed description will be first given of a vehicle-mounted device that executes the host system detection method disclosed in the embodiments of the present application.

The peripheral interface 114 couples various input/output devices to the processor 113 and memory 111. In some embodiments, the peripheral interface 114, the processor 113, and the memory controller 112 may be implemented in a single chip.

For example, a security guard or the like detection application may be installed on the in-vehicle apparatus 100 to detect the host system.

The vehicle-mounted device 100 in the present embodiment may be configured to execute each step in each method provided in the embodiments of the present application. The following describes the implementation process of the host system detection method in detail by several embodiments.

Please refer to fig. 2, which is a flowchart illustrating a host system detection method according to an embodiment of the present disclosure. The specific process shown in fig. 2 will be described in detail below.

Step 210, after the target host system of the target vehicle is started, a detection file is acquired.

The detection file is used for recording the detection progress of the target host system. Illustratively, the inspection file may include historical inspection progress, inspected items, how long the items were inspected, and the like. The detection items may refer to various applications in the target host system; or the content loaded by each historical browsing website; but also a local file of the device on which the target host system is located, etc.

The instrumentation file may be updated as the target host system is instrumented.

The speed at which the detection file is updated may vary with the speed at which the target host system is detected. For example, the inspection file is updated every time an item to be inspected on the target host system is inspected.

The speed at which the detection file is updated may be set in advance. For example, the detection file is updated at preset intervals according to the detection condition of the target host system. For example, the preset interval may be a time interval of 0.5, 1 second, 3 seconds, 10 seconds, or the like.

Illustratively, the test file may be initially processed when it is first created. The detection file can comprise a plurality of variables, and each variable is used for recording historical detection progress, detected items and detection duration of each detection item. In the detection process of the target host system, the history detection progress, the detected items and the detection duration of each detection item can be recorded by updating each variable.

For example, if the test file cannot be obtained, it means that the target host system is tested for the first time, the test file can be newly created, and the test file is initialized.

Illustratively, the initialization of the test file may include variables required to build the test file. The initialization may also include setting a default value for a variable in the test file.

And step 230, determining the current detection item of the target host system according to the detection file.

For example, the last test item detected by the target host system during the last boot process may be recorded in the test file.

For example, the check file may only record the progress of the target host system being checked during the last boot process. The detected progress of the target host system can be determined according to the detection file in the last starting process of the vehicle, so that the last detected item in the last starting process of the vehicle can be determined.

Alternatively, the detection order of the respective detection items in the target host system may be preset. Illustratively, the next test item of the last test item may be the current test item of the target host system. For example, in order to avoid that the last detection item is not detected when the target vehicle is turned off last time, the last detection item may also be used as the current detection item of the target host system.

The current detection item can be used as a detection starting point for starting the target vehicle at this time.

The detection order may be an order obtained by sorting names of the detection items, or the detection order may be a sorting order in which files corresponding to the detection items are located as folders. The embodiments of the present application are not limited to the setting of the detection order.

And 250, detecting the target host system according to the current detection item.

For example, the target host system may be detected according to a preset detection order with the current detection item as a detection starting point.

Through the steps, the periodic detection of the target host system can be realized, so that the situation that the detection items ranked in the front are repeatedly detected and the detection items ranked in the back are not detected for multiple times can be reduced.

In order to reduce the problem that part of detection items are not detected in the process of starting the vehicle once, the target host system can be detected again from the beginning after the subsequent detection items of the current detection item in the target vehicle are detected, so as to start a new detection period. Illustratively, step 250 may then be implemented as: and periodically detecting the target host system according to a set period.

The set period may be a duration of each detection period, and may be, for example, 100s, 150s, 200s, or the like.

The set period may also be a time period set by the user, for example, the set period may be 1 day, 2 days, or the like. The detection is restarted once per set period. For example, a complete test is performed once in a set period, and after one day, a new round of testing of the host system may be initiated.

In this embodiment, in the detection process of the target host system, the update of the detection file may also be implemented, and step 250 may include: detecting the detection items behind the current detection item, and updating the detection file based on the detection progress; and initializing the detection file after the detection of the host system is finished.

For example, the update frequency of the detection file may be dynamically set as needed, or after a default update frequency is set, the update frequency of the detection file is subsequently updated at the default frequency.

In one embodiment, the detection file may also record the detection items that have been detected in the current detection period. Step 230 may include step 231, step 232 and step 233.

Step 231, determining the first detection item set which has been detected in the target host system according to the detection file.

Illustratively, one of the variables in the test file is used to record the identification of each test item that has been currently tested. Each detection item can have a unique identifier, and after each detection item is detected, the variables of the detection file can be updated.

Illustratively, the variable corresponding to each detection item can be included in the detection file. When the variable is a first value, the detection item corresponding to the variable is in an undetected state, and when the variable is a second value, the detection item corresponding to the variable is in a detected state. For example, the first value is 0 and the second value is 1.

Step 232, removing the first detection item set from all detectable item sets in the target host system, and determining a second detection item set needing to be detected.

For example, the set of all detectable items may be all of the detectable items that need to be detected by default in the target host system, or may be the detected items screened from all of the detectable items that need to be detected by default.

Step 233, determine the current detection item from the second detection item set.

For example, the current detection item may be determined in the second detection item set according to a preset detection order. For example, a target detection item in the detection items of the second detection item set may be taken as a current detection item, where the target detection item is a top detection item in a preset detection order.

In another embodiment, only the last detected detection item in the current detection period may be recorded in the detection file. Step 230 may include: step 234 and step 235.

And step 234, determining the last detected historical detection item of the target host system according to the detection file.

Illustratively, one of the variables in the test file is used to record the last test history. Each detection item can have a unique identifier, and each detection item can be updated in the detection file variable to be the detection item which is currently detected.

And 235, determining a current detection item according to the historical detection items.

For example, the next detection item in the historical detection items may be ranked as the current detection item according to a preset detection order.

Illustratively, the historical detection item may also be used as the current detection item.

Through the relevant steps in step 230, the detection starting point required by the current detection can be more accurately determined based on the content in the detection file, so that the detection items remaining after the previous detection can be further detected, and the safety of the vehicle where the target host system is located is improved.

In order to adapt to the use requirements of various drivers or different safety requirements of different vehicles, the detection items which need to be detected currently in the target host system can be adjusted adaptively. Therefore, under the requirement, before step 250, the host system detection method may further include: step 241 and step 242.

Step 241, receive a pause request.

The suspend request carries an item to be suspended.

For example, a display interface may be provided on the vehicle where the target host system is located, and an operation window may be provided in the display interface, and the pause request may be submitted by selecting the detection item to be paused in the operation window.

Thus, after step 241, step 250 may be implemented as: and in the detection process, filtering out the items to be suspended.

Optionally, the detection items to be detected may be loaded in a detection list, and the items to be suspended in the original list may be removed to obtain an updated detection list. Each detection item in the updated detection list can be detected.

At step 242, a restart request for the suspended detection item is received.

The restart request carries an item to be restarted.

Illustratively, the restart request can be submitted by selecting the detection item needing to be restarted in the operation window.

Thus, after step 242, step 250 may be implemented as: and adding the items to be restarted into a detection list, and detecting the detection items in the detection list.

In the host system detection method provided by the embodiment of the application, the historical detection condition is recorded in the detection file, and when a vehicle is started next time, the current detection item can be determined according to the detection file, so that the subsequent detection item can be continuously detected according to the progress of the previous detection. Therefore, the situation that detection cannot be realized by repeatedly detecting and sequencing the files needing to be detected in the front and detecting items needing to be detected in the back for multiple times of vehicle starting can be avoided, the detection coverage of the host system of the vehicle is wider, and the safety of the host system of the vehicle can be improved.

In the embodiment of the application, as the host system is periodically detected, the method can effectively solve the problem of missing detection possibly existing in the host detection technology of vehicle operation, and the problem of missing detection is solved on the basis of not influencing the original function and performance. Furthermore, because an item needing to be paused can be set, and the item which is paused can also be restarted, the independence of each item detection can be not influenced, the expansibility is better, and a plurality of operating systems are supported.

In the embodiment of the application, as the progress measurement is recorded in the local storage detection file, the detection record which is not run last time is firstly obtained every time the host system runs, and then the detection progress of the current detection item is obtained, and the corresponding detection progress is filtered or jumped to start running detection. Therefore, the detection items ranked in the front can be reduced from being detected for multiple times, and the detection items ranked in the back can be omitted for detection. Further, the detection file can be a local file, and the progress of real-time cache detection can be realized. And compared with a database, the detection file record is simple and convenient, and the detection file is stored and transplanted to be more concise. The method supports multiple operating systems, and has low coupling degree with the kernel and good expansibility. The host detection technology running on the vehicle machine with a long running period can be implemented according to the host system detection method in the embodiment, and the independence of each detection technology cannot be influenced.
