[0002] At present, with the rapid development of vehicle intelligence, the car computer system in the vehicle will also be quickly upgraded and iterated. In order to cope with the rapid upgrade and iteration of the car computer system, the car computer system in the vehicle is generally upgraded online, that is, the latest car computer system installation package (also called car computer upgrade package) is downloaded through the WIFI network or Internet of Things connected to the vehicle, and the car computer system in the vehicle is upgraded and iterated through the car computer system installation package.

[0003] However, the vehicle system will require a large amount of storage space during the upgrade and iteration process (the size of the storage space required for the upgrade is generally much larger than the size of the vehicle system installation package, and may be many times the size of the vehicle system installation package). As a result, the vehicle can download the vehicle system installation package, but the remaining storage space in the vehicle's vehicle system is insufficient to support the upgrade. Currently, once the vehicle's vehicle system detects that the storage space of the vehicle system is insufficient for an upgrade, it will stop the corresponding upgrade operation, resulting in the actual online upgrade being limited, making it difficult to complete the automatic online upgrade of the vehicle system.

[0069] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0070] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0071] Based on this, the embodiment of the present application provides a vehicle system upgrade method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle system upgrade method of the present application.

[0072] In this embodiment, the vehicle system upgrade method includes steps S10 to S40:

[0073] Step S10: when it is detected that the vehicle computer system needs to be upgraded and the available memory of the vehicle computer system does not meet the system upgrade requirement, at least one releasable resource is acquired.

[0074] It should be noted that the executor of this embodiment can be the vehicle itself or a vehicle system upgrade device installed in the vehicle. The vehicle system upgrade device can be a controller in the vehicle, such as an ECU or other controllers. This embodiment does not limit this. In this embodiment and the following embodiments, the vehicle system upgrade method of this application is explained by taking the vehicle system upgrade device as an example.

[0075] It should be noted that the vehicle system upgrade device can be connected to the vehicle management platform (or management server), and can regularly obtain the latest version number of the vehicle system from the vehicle management platform. If the version number of the vehicle system in the vehicle is lower than the latest version number of the vehicle system, it can be determined that the vehicle system needs to be upgraded. The available memory of the vehicle system can be the available storage space in the vehicle system of the vehicle. The system upgrade requirements may include the storage space required when upgrading the vehicle system.

[0076] In actual use, when setting up the latest vehicle system, the relevant managers or developers of the vehicle management platform can determine the storage space required for the latest vehicle system upgrade package to upgrade the vehicle system based on actual vehicle verification and other methods, and set the system upgrade requirements for the vehicle system upgrade package.

[0077] In actual application, the vehicle system upgrade equipment can obtain the latest system upgrade requirements corresponding to the vehicle system from the connected vehicle management platform, and compare the available memory of the vehicle system with the system upgrade requirements. If the available storage space in the vehicle system is less than the storage space required when upgrading the vehicle system, it can be determined that the available memory of the vehicle system does not meet the system upgrade requirements.

[0078] It is understandable that if the vehicle system needs to be upgraded and the available memory of the vehicle system does not meet the system upgrade requirements, it can be determined that if no processing is performed at this time, the online upgrade will definitely fail due to insufficient resources. At this time, in order to ensure that the vehicle system can be upgraded normally, it is necessary to increase the size of the available storage space in the vehicle system. At this time, it is necessary to try to release some resources. Therefore, at least one releasable resource can be obtained.

[0079] Among them, the releasable resources may include at least one of the vehicle application cache, offline map data package, multimedia resource package, installed vehicle application, etc.

[0080] Step S20: clearing the releasable resources in the vehicle system and recording cleared resource data.

[0081] It should be noted that after determining the releasable resources, the releasable resources in the vehicle system can be cleaned up to increase the size of the available storage space in the vehicle system. In order to ensure the actual usage experience of vehicle users, it is necessary to ensure that the cleaned resources can be restored subsequently. Therefore, while cleaning the releasable resources in the vehicle system, the cleaned resource data can also be recorded. By recording the information of the cleaned related resource data, it can be ensured that it can be restored later.

[0082] In actual use, the recorded cleaning resource data can be stored in a pre-set cleaning resource list. The cleaning resource list can be set in a specific storage space in the vehicle system upgrade device that will not be cleaned or overwritten when the vehicle system is upgraded. Of course, setting the cleaning resource list in the vehicle system upgrade device may still be risky (occupying storage space, which may affect the upgrade process, and may also be cleaned up if set incorrectly). In order to avoid risks, the cleaning resource list can also be set in the vehicle management platform.

[0083] Step S30: If the available memory of the vehicle computer system meets the system upgrade requirements after cleaning, then the vehicle computer upgrade package is downloaded, and the vehicle computer system is upgraded according to the vehicle computer upgrade package.

[0084] It should be noted that after cleaning, the available storage space in the vehicle system can be regained. If the available storage space in the vehicle system is greater than or equal to the storage space required when upgrading the vehicle system, it can be determined that the available memory of the vehicle system meets the system upgrade requirements.

[0085] Of course, since it may be time-consuming to count the available storage space in the vehicle system, when it is determined in step S10 that the available memory of the vehicle system does not meet the system upgrade requirements, the total amount of storage space to be released can be calculated based on the available memory of the vehicle system and the system upgrade requirements. After cleaning, the total amount of storage space released by the cleaning resources is obtained. If the total amount of storage space released is greater than or equal to the total amount of storage space required to be released, it can be determined that the available memory of the vehicle system meets the system upgrade requirements.

[0086] For example: Assuming that step S10 determines that the available memory of the vehicle system does not meet the system upgrade requirements, the total amount of storage space to be released is calculated as a based on the available memory of the vehicle system and the system upgrade requirements. When cleaning, the releasable resources cleaned up include four types: machine application cache, offline map data package, multimedia resource package, and installed vehicle application. After cleaning various releasable resources, the sizes of released storage space are b1, b2, b3, and b4 respectively. The total amount of storage space released by cleaning resources is b=b1+b2+b3+b4. If a<b at this time, it can be determined that the available memory of the vehicle system meets the system upgrade requirements.

[0087] It is understandable that if the available memory of the vehicle system meets the system upgrade requirements after cleaning, it means that the vehicle system can be upgraded online at this time. Therefore, the vehicle upgrade package can be downloaded, and then the vehicle system can be upgraded according to the vehicle upgrade package.

[0088] Among them, the vehicle computer upgrade package can be downloaded from the vehicle management platform.

[0089] Step S40: During the upgrade process and / or after the upgrade is completed, restore the resources of the vehicle system according to the recorded cleanup resource data.

[0090] It should be noted that since some resources in the vehicle system may have been cleared before, during the upgrade process and / or when the upgrade is completed, the resources of the vehicle system can be restored based on the recorded cleared resource data, and the previously cleared resources can be reloaded into the vehicle system to avoid affecting the actual use of the user.

[0091] In actual use, after the cleaning is completed, the downloaded car computer upgrade package can be cleared to avoid occupying too much storage space. Specifically, after the car computer system online upgrade (OTA) is completed, the car computer upgrade package can be deleted and the data can be restored without feeling at the same time. The implementation method is:

[0092] The deletion of the vehicle upgrade package adopts a separate deletion process, and the recovery of each resource data also adopts a separate process. For example, the navigation offline map data package, audio and video APP, and application store all have separate deletion and download recovery processes. In the process of deleting the vehicle upgrade package, the memory space size is monitored in real time. Once there is enough space, the deleted resources can be restored in batches. For example, if the memory is enough for the offline map of a certain city in the offline map data, it will be downloaded and restored first. And so on, eventually multiple processes can be carried out simultaneously, and the cleared data can be restored synchronously in batches to ensure that users can experience better and seamless recovery.

[0093] Of course, the vehicle computer upgrade package can also be stored in the vehicle computer system as a system backup. At this time, only the remaining storage space of the vehicle computer system will be detected. When the free capacity of the storage space is sufficient, resources will be restored. This embodiment does not limit this.

[0094] For ease of understanding, now combined Figure 2 This is for illustration only, but not for limitation. Figure 2 This is a schematic diagram of the vehicle system upgrade timing of this embodiment.

[0095] like Figure 2 As shown, the complete execution process of the vehicle system upgrade method includes: multiple execution steps from resource file deletion to resource file download recovery #2, during which process, process 1 is responsible for resource file deletion (i.e., cleanup of released resources), process 2 is responsible for downloading, decompressing and decrypting the upgrade package (i.e., vehicle upgrade package), process 3 is responsible for managing partition A, which represents the vehicle system before the upgrade, and process 4 is responsible for managing partition B, which represents the vehicle system after the upgrade;

[0096] Before the restart, the system of partition A is still running. During the upgrade process, some storage space will be gradually released due to the deletion of upgrade packages (compressed packages) or the cleaning of loaded files during the upgrade process. Based on this, the system of partition A that is still running can be used to download and restore resource files. When the upgrade is completed, resource files can also be downloaded and restored.

[0097] Therefore, there are two opportunities for resource file download resumption, namely Figure 2 As shown in , the resource file download resumes at #1 (i.e. during the upgrade process) and the resource file download resumes at #2 (i.e. after the upgrade is completed);

[0098] If there are fewer resource files to be cleaned up, the resource recovery may be completed in the relevant steps of resource file download recovery #1. In this case, the resource file download recovery #2 step may not be executed, that is, the resources of the vehicle system are only recovered during the upgrade process;

[0099] If there are many cleaned resource files, they may not be completely restored in the related steps of resource file download recovery #1. In this case, some cleaned resources can be restored in the step of resource file download recovery #1, and then the step of resource file download recovery #2 can be executed to restore the remaining resource files, so as to ensure that the previously deleted resource files are restored as completely as possible, that is, the resources of the vehicle system are restored during the upgrade process and after the upgrade is completed;

[0100] Of course, if necessary (such as if you are worried that restoring resource files will affect system restart), you can also not execute the relevant steps of resource file download and recovery #1, and only execute the steps of resource file download and recovery #2, that is, only restore the resources of the vehicle system when the upgrade is completed.

[0101] Among them, some cleared resources may require the upgraded vehicle system to start (i.e. Figure 2 For such resources, they can be restored only in the step of resource file download recovery #2, or restored in conjunction with source file download recovery #1 and source file download recovery #2. For example, because the old system (the system before the upgrade) will be discontinued later, the cleared car computer applications need to be installed after the updated car computer system is started to truly realize resource recovery. In this case, the car computer application can be restored only when executing source file download recovery #2; or the installation package of the car computer application can be downloaded when executing source file download recovery #1, and the downloaded installation package can be installed when executing source file download recovery #2, thereby realizing the recovery of the car computer application.

[0102] This embodiment provides a method for upgrading a vehicle computer system. When the available memory of the vehicle computer system does not meet the upgrade requirements, some resources in the vehicle computer system can be automatically released to ensure that the vehicle computer system can be updated normally. After the update, the released resources will also be restored to ensure that the user has no sense of operation as much as possible and avoid affecting the user's actual operation.

[0103] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 3 , step S10 includes steps S101 to S102:

[0104] Step S101: when it is detected that the vehicle computer system needs to be upgraded and the available memory of the vehicle computer system does not meet the system upgrade requirement, a resource priority queue is obtained.

[0105] Step S102: extracting at least one releasable resource from the resource priority queue.

[0106] It should be noted that the resource priority queue contains a variety of releasable resources (such as all or part of the releasable resources set by the administrator of the vehicle system upgrade equipment), and the various releasable resources are sorted from high to low according to the release priority. The release priority is used to characterize the degree of impact on the actual use of the user after the releasable resources are cleared. The higher the release priority, the smaller the impact on the actual use of the user after the corresponding releasable resources are cleared.

[0107] For example: assuming that the releasable resources include vehicle application cache, offline map data package, multimedia resource package and installed vehicle application, and the impact on the actual user usage after cleaning is the smallest for application cache, followed by map data package, then multimedia resource package, and the largest for installed vehicle application, then the resource priority queue can be "vehicle application cache-offline map data package-multimedia resource package-installed vehicle application".

[0108] In actual use, at least one releasable resource may be extracted from the queue head of the resource priority queue, wherein the queue head may be the side with the highest release priority in the queue, and the extracted releasable resource will be removed from the resource priority queue.

[0109] In this embodiment, after step S20, steps S30'-S40' are further included:

[0110] Step S30 ′: if the available memory of the vehicle system still does not meet the system upgrade requirement after the cleaning, then it is detected whether there are any unextracted releasable resources in the resource priority queue.

[0111] Step S40': If yes, return to the step of extracting at least one releasable resource from the resource priority queue.

[0112] It should be noted that if after cleaning, the available memory of the vehicle system still does not meet the system upgrade requirements, it means that even after cleaning, the size of the available storage space in the vehicle system is still smaller than the size of the storage space required when upgrading the vehicle system. You can try to continue releasing resources. Therefore, you can detect whether there are any unextracted releasable resources in the resource priority queue.

[0113] It is understandable that if there are still unextracted releasable resources in the resource priority queue, the releasable resources can continue to be extracted from the resource priority queue, and attempts to release the resources can continue, so the process can return to step S102.

[0114] In a feasible implementation, the releasable resources may include a vehicle machine application cache, and in order to ensure that the impact on user operations when releasing resources is as small as possible, step S20 in this embodiment may include:

[0115] Obtaining a target vehicle-machine application in the vehicle-machine system;

[0116] Sorting the target vehicle computer applications from low to high according to the corresponding usage frequencies, and generating a sorting result;

[0117] The top N target vehicle computer applications in the sorting result are used as applications to be cleaned up;

[0118] Perform cache cleaning on the application to be cleaned, and obtain the total amount of cache cleaning data;

[0119] The resource data is cleaned up according to the total amount of cleaned up data.

[0120] It should be noted that the target vehicle-mounted application is a vehicle-mounted application that is set in the vehicle-mounted system and has an application cache. The application cache can be temporary data stored on the device by the vehicle-mounted application to speed up the application loading speed and improve the user experience. Clearing such temporary data will cause the subsequent vehicle-mounted application to load more slowly, or cause some user settings or change information to be lost, which will have a certain impact on the actual use of the user, but the overall impact is small. Therefore, you can try to increase the available storage space in the vehicle-mounted system by clearing the cache.

[0121] In actual use, in order to minimize the impact on the actual use of users, when clearing the cache, you can give priority to clearing the cache in the car computer applications that are used less frequently by users. Therefore, you can first scan the car computer system to determine the target car computer applications with application caches, and then sort the target car computer applications from low to high according to the usage frequency corresponding to each target car computer application. Then, the top N target car computer applications in the sorting result are used as applications to be cleaned, and finally, the cache of the applications to be cleaned is cleaned.

[0122] Wherein, N can be a positive integer and can be pre-set by the administrator of the vehicle system upgrade device. Cache cleaning can call the cache cleaning tool or interface provided by the application to be cleaned to achieve cache cleaning, or it can be performed through a global cleaning tool (such as security guard), which is not limited in this embodiment. The usage frequency corresponding to the target vehicle application can be the number of times the target vehicle application is used within a preset time range (such as 30 days).

[0123] In actual application, since application cache recovery is difficult and the recovery value is relatively low, cache recovery may not be attempted, but the user needs to be able to confirm that the cache has been cleared. Therefore, after the clearing is completed, the clearing resource data may be recorded only based on the total amount of cache clearing data.

[0124] Specifically, the implementation process of recording the cleaning resource data according to the total amount of cleaning data of the cache cleaning may be to construct the cleaning resource data according to the total amount of cleaning data of the cache cleaning, and add the cleaning resource data to the cleaning resource list.

[0125] In a feasible implementation, the releasable resource may include an offline map data package, and in order to ensure that the impact on user operations when releasing resources is as small as possible, step S20 in this embodiment may include:

[0126] Obtaining a data retrieval interface corresponding to the map navigation software in the vehicle system;

[0127] Obtaining the offline map data package in the vehicle system by calling the data retrieval interface;

[0128] Sort each offline map data package from low to high based on the corresponding map usage frequency to obtain a map sorting result;

[0129] The top N offline map data packets in the map sorting result are used as the map data packets to be cleaned up;

[0130] The map data packet to be cleared is cleared, and resource data is cleared according to the data packet information record corresponding to the map data packet to be cleared.

[0131] It should be noted that offline map data packets can be map data packets that are downloaded and stored locally by map navigation software for ease of use. However, offline map data packets of general map navigation software are usually encrypted or specially processed (such as file name obfuscation, or data packets in a specific format). It is difficult for the vehicle system upgrade device to directly scan offline map data packets. In order to obtain relevant information of offline map data packets, the data retrieval interface corresponding to the map navigation software in the vehicle system can be obtained first, and then the offline map data packets in the vehicle system can be obtained by calling the data retrieval interface.

[0132] Among them, the data retrieval interface corresponding to the map navigation software can be an interface provided by the map navigation software for managing offline map data packets, and the manager of the vehicle system upgrade equipment can parse and determine the instructions for use or code description of the map navigation software in advance.

[0133] In actual use, there may be multiple map navigation software installed in the vehicle system, and the data retrieval interface corresponding to each map navigation software may also be different. In order to ensure that the data retrieval interface can be correctly obtained, the manager of the vehicle system upgrade equipment can pre-set the navigation software interface mapping table. The mapping relationship between each map navigation software and the data retrieval interface is stored in the navigation software interface mapping table. At this time, the specific implementation process of obtaining the data retrieval interface corresponding to the map navigation software in the vehicle system can be to read the data retrieval interface corresponding to the map navigation software from the navigation software interface mapping table.

[0134] In actual use, since there is a possibility of recovery failure during subsequent recovery, in order to minimize the impact on user operations, when cleaning, you can give priority to cleaning offline map data packages that are used less frequently by users. Therefore, you can sort each offline map data package from low to high according to the map usage frequency corresponding to each offline map data package to obtain a map sorting result. Afterwards, the top N offline map data packages in the map sorting result are used as map data packages to be cleaned.

[0135] Wherein, N may be a positive integer and may be pre-set by the administrator of the vehicle system upgrade device. The map usage frequency corresponding to the offline map data package may be the number of times the offline map data package is loaded and used within a preset time range (eg, within two months).

[0136] In actual application, the map package cleaning interface provided by the map navigation software can be used to clean up the map data package to be cleaned, or the file corresponding to the map data package to be cleaned can be directly cleaned, which is not limited in this embodiment.

[0137] In order to ensure that the offline map data package can be restored and cleared automatically after the system upgrade is completed, the resource data can be cleared according to the data package information record corresponding to the map data package to be cleared. Specifically, the resource data can be constructed according to the data package information, and then the resource data can be added to the resource list.

[0138] Among them, since the map navigation software generally requires at least a map area (such as province, city, street, etc.) when downloading an offline map data package, and in order to distinguish which map navigation software the cleared offline map data package belongs to, when constructing the cleanup resource data, the data package information used includes at least the map area corresponding to the offline map data package, and the map navigation software to which the offline map data package belongs.

[0139] Of course, if necessary, the data packet information may also include other information. For example, for verification purposes, it may also include the map package size corresponding to the offline map data packet; in order to ensure that the restored offline map data packet can be correctly loaded by the map navigation software, it may also include the file name, storage path and other information of the offline map data packet.

[0140] Of course, if necessary, you can also store the map data package to be cleared in the cloud first and then clear it. Later, you can use the cloud stored files to restore it.

[0141] In a feasible implementation, the releasable resources may include multimedia resource packages (such as video resources, audio resources, etc.), and in order to ensure that the impact on user operations when releasing resources is as small as possible, step S20 in this embodiment may include:

[0142] Acquire a multimedia resource package in the vehicle system;

[0143] Obtain the last usage time and usage frequency corresponding to each multimedia resource package;

[0144] The multimedia resource packages whose corresponding last usage time is not within the preset time range are taken as the resource packages to be selected;

[0145] Sorting the resource packages to be selected from low to high according to the usage frequencies corresponding to the resource packages to be selected, to obtain a multimedia sorting result;

[0146] The top N resource packages to be selected in the multimedia sorting result are used as resource packages to be cleaned up;

[0147] Perform cloud storage on the resource package to be cleaned and obtain a cloud storage path;

[0148] The resource data is cleaned up according to the cloud storage path and the resource information record of the resource package to be cleaned up, and the resource package to be cleaned up is cleared.

[0149] It should be noted that in order to minimize the impact on user operations, it is necessary to screen the multimedia resource packages in the vehicle system, so that the last usage time and usage frequency corresponding to each multimedia resource package can be obtained. The preset time range can be pre-set by the administrator of the vehicle system upgrade equipment, and the specific time range is close to the current time, such as setting the preset time range to within a week or a month from the current time.

[0150] Since there is a possibility of recovery failure during subsequent recovery, it is necessary to avoid clearing the multimedia resource packages that the user has recently used. If the last usage time corresponding to the multimedia resource package is not within the preset time range, it means that the user has not used the multimedia resource package recently. Therefore, such multimedia resource packages can be used as multimedia sorting results.

[0151] In order to minimize the impact on users' actual use, when cleaning multimedia resource packages, the less frequently used parts can be cleaned up first. Therefore, the resource packages to be selected can be sorted from low to high according to the usage frequency corresponding to each resource package to be selected, and the multimedia sorting result can be obtained. After that, the top N resource packages to be selected in the multimedia sorting result are used as resource packages to be cleaned.

[0152] Wherein, N may be a positive integer and may be pre-set by the administrator of the vehicle system upgrade device. The usage frequency corresponding to the resource package to be selected may be the number of times the resource package to be selected is loaded and played within a preset time range (such as within two months or a longer time range).

[0153] In actual application, it is actually difficult to obtain a suitable download path for multimedia data packets (due to the data differences of multimedia data packets and the difficulty in determining the data source). In order to ensure that the cleaned multimedia data packets can be restored later, the resource package to be cleaned can be transmitted to a cloud storage server for cloud storage, and the corresponding cloud storage path can be obtained. According to the cloud storage path and the resource information of the resource package to be cleaned, the cleaned resource data is recorded, and the resource package to be cleaned is cleared;

[0154] Specifically, the implementation process of recording the cleanup resource data according to the cloud storage path and the resource information of the resource package to be cleaned up may be to construct the cleanup resource data according to the cloud storage path and the resource information of the resource package to be cleaned up, and add the cleanup resource data to the cleanup resource list.

[0155] Among them, in order to ensure that the restored multimedia resource package can be verified subsequently, the resource information includes the resource package size of the multimedia resource package. In order to ensure that the multimedia software originally associated with the subsequently restored multimedia resource package is loaded normally, the resource information may also include the multimedia software to which the multimedia resource package belongs. In order to ensure that the storage path of the subsequently restored multimedia resource package remains unchanged and to ensure that the user can obtain the multimedia resource package according to their original habits, the resource information may also include the storage path of the multimedia resource package in the vehicle system.

[0156] In a feasible implementation, the releasable resources may include installed vehicle-mounted applications. In order to ensure that the impact on user operations when releasing resources is as small as possible, step S20 in this embodiment may include:

[0157] Obtaining uncommon applications in the vehicle system;

[0158] Using a portion of the uncommonly used applications provided by the application market as applications to be selected;

[0159] Sort the applications to be selected from low to high according to the usage frequencies corresponding to the applications to be selected, and obtain the application sorting result;

[0160] The top N applications to be selected in the application sorting result are used as applications to be cleaned;

[0161] The resource data is cleaned up according to the application information corresponding to the application to be cleaned up, and the application to be cleaned up in the vehicle system is uninstalled.

[0162] It should be noted that uncommon applications may be installed car applications that are set in the car system and have not been started within the preset time range, that is, car applications that have not been used recently. The preset time range can be pre-set by the administrator of the car system upgrade equipment, specifically a time range close to the current time, such as setting the preset time range to within a week or a month from the current time.

[0163] In actual use, the vehicle system can generally only automatically install applications from specific channels. When cleaning up installed vehicle applications, it is necessary to avoid clearing vehicle applications that cannot be automatically installed by the vehicle system. Therefore, the part of the infrequently used applications provided by the application market can be used as the application to be selected, that is, the part of the infrequently used applications that can be downloaded from the application market can be used as the application to be selected. The application market here can be the vehicle manufacturer, or an application market provided by an enterprise with industry authority.

[0164] When actually cleaning up applications, in order to minimize the impact on actual user use, when cleaning up installed car-mounted applications, you can prioritize cleaning up the less frequently used applications. Therefore, you can first sort each application to be selected from low to high according to its corresponding usage frequency to obtain the application sorting result, and use the top N applications to be selected in the application sorting result as applications to be cleaned. Record and clean up resource data according to the application information corresponding to the applications to be cleaned, and uninstall the applications to be cleaned in the car-mounted system.

[0165] Specifically, the implementation process of recording the cleaning resource data according to the application information corresponding to the application to be cleaned may be: constructing the cleaning resource data according to the application information corresponding to the application to be cleaned, and adding the cleaning resource data to the cleaning resource list.

[0166] Wherein, N may be a positive integer and may be pre-set by the administrator of the vehicle system upgrade device. The usage frequency corresponding to the to-be-selected application may be the number of times the to-be-selected application is started and / or operated within a pre-set time range (eg, within two months or longer).

[0167] In actual use, since applications are downloaded from the application market, at least a unique identifier of the application (such as the application name or the application number in the application market) is required, and applications generally have multiple versions, and the functions of each version may be different. In order to ensure that the subsequently restored application is consistent with the uninstalled application, the application information used when constructing the cleanup resource data includes at least the application version number and the application identifier. If necessary, other information may also be included, such as the application file size.

[0168] Of course, if necessary, the application files of the application to be cleaned can be stored in the cloud before uninstalling, and then the application files stored in the cloud can be used for restoration.

[0169] For different releasable resources, the preset parameters configured therefor may be different, that is, for different releasable resources, different N values, preset time ranges, etc. may be set.

[0170] It should be noted that if after cleaning, the available memory of the vehicle system still does not meet the system upgrade requirements, and there are no unextracted releasable resources in the resource priority queue, the automatic upgrade of the vehicle system can be stopped;

[0171] Of course, you can also modify the corresponding parameters (such as increasing the N value, modifying the preset time range, modifying the statistical period for statistical usage frequency, etc.), and then rebuild the resource priority queue, and then return to step S102 to continue trying to clean up resources.

[0172] This embodiment provides a method for upgrading a vehicle system. Since each releasable resource can be sorted according to the release priority, a resource priority queue can be constructed, and the resources in the vehicle system can be gradually released based on the resource priority queue, ensuring that when resources need to be released for automatic upgrading of the vehicle system, the impact on actual user use is minimized as much as possible.

[0173] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as those in the first embodiment can be referred to the above description, and will not be described in detail later. Figure 4 , step S40 includes steps S401 to S403:

[0174] Step S401: During the upgrade process and / or when the upgrade is completed, obtain the recorded cleanup resource data.

[0175] It should be noted that since some resources in the vehicle system may have been cleared before the vehicle system is upgraded, in order to avoid reducing the user's actual usage experience as much as possible, when the vehicle system is upgraded, it is necessary to restore the previously cleared resources as much as possible. Therefore, the recorded cleanup resource data can be obtained.

[0176] Specifically, obtaining the recorded cleaning resource data may be reading the corresponding cleaning resource data from the cleaning resource list.

[0177] Among them, since more than one or more than one resource may be cleared when clearing resources, the cleanup resource list may contain multiple records. At this time, the multiple records in the cleanup resource list can be processed sequentially to restore the corresponding resources, such as traversing the cleanup resource list.

[0178] Step S402: Acquire releasable resources corresponding to the cleanup resource data.

[0179] It should be noted that the construction method and data used for cleaning resource data of different releasable resources are different. At this time, it is possible to determine which releasable resource the cleaning resource data corresponds to based on the data and / or construction format in the cleaning resource data.

[0180] Step S403: If the releasable resource is a recoverable resource, the vehicle system is restored according to the cleaned resource data.

[0181] It should be noted that the recoverable resources may be releasable resources of non-application cache type. This is because application cache recovery is difficult and the recovery value is relatively low, so cache recovery may not be attempted. Therefore, all releasable resources except for the application cache type may be set as recoverable resources.

[0182] If the resources are recoverable, the vehicle system can recover the resources based on the cleaned resource data.

[0183] For ease of understanding, the following example is given:

[0184] Assuming that the releasable resources include the vehicle application cache, offline map data package, multimedia resource package and installed vehicle application, then the recoverable resources may include the offline map data package, multimedia resource package and installed vehicle application;

[0185] At this time, the recovery methods for offline map data packages can be divided into two categories:

[0186] 1. The map area and map navigation software can be extracted from the cleaned resource data, and then the offline map download interface in the map navigation software is called to download the offline map data package of the map area;

[0187] 2. If the cleaned map data package to be cleaned has been stored in the cloud before, the cloud storage path, data package size and storage path of the offline map data package in the vehicle system can be extracted from the cleaned resource data at this time, and the file corresponding to the cloud storage path can be downloaded. The size of the downloaded file can be verified by the data package size. If the sizes are consistent, the downloaded file can be stored in the storage path of the offline map data package in the vehicle system;

[0188] Of course, the above two methods can also be combined, for example: download the file corresponding to the cloud storage path, verify the size of the downloaded file by the size of the data packet, and if the sizes are the same, store the downloaded file in the storage path of the offline map data packet in the vehicle system;

[0189] If the sizes are inconsistent, the map area and the map navigation software are extracted from the cleaned resource data, and then the offline map download interface in the map navigation software is called to download the offline map data package of the map area.

[0190] For multimedia resource packages, the recovery method is: extract the cloud storage path, resource package size and storage path of the multimedia resource package in the vehicle system from the cleaned resource data, then download the file corresponding to the cloud storage path, and verify the downloaded file size through the resource package size. If the sizes are consistent, the downloaded file will be stored in the storage path of the multimedia resource package in the vehicle system.

[0191] For installed car applications, the recovery methods can be divided into two types:

[0192] 1. Extract the application version number and application ID from the cleaned resource data, download the corresponding vehicle application package in the application market according to the application version number and application ID, and install it, so as to restore the installed vehicle application;

[0193] 2. Previously, the application files of the cleaned applications were stored in the cloud. At this time, the cloud storage path, application file size and storage path of the application files in the vehicle system can be extracted from the cleaned resource data, and the file corresponding to the cloud storage path can be downloaded. The size of the downloaded file can be verified by the application file size. If the sizes are consistent, the downloaded file will be stored in the storage path of the application files in the vehicle system. Afterwards, the corresponding global parameter settings or application registry additions can be performed on the application in the vehicle system.

[0194] Of course, the above two methods can also be combined, such as:

[0195] Extract the cloud storage path, application file size and storage path of the application file in the vehicle system from the cleaned resource data, download the file corresponding to the cloud storage path, verify the size of the downloaded file by the application file size, if the sizes are the same, store the downloaded file in the storage path of the application file in the vehicle system, and then perform corresponding global parameter settings or application registry addition on the application in the vehicle system;

[0196] If the sizes are inconsistent, the application version number and application identifier are extracted from the cleaned resource data, and the corresponding vehicle application package is downloaded from the application market according to the application version number and application identifier, and installed, thereby realizing the recovery of the installed vehicle application.

[0197] This embodiment provides a method for upgrading a vehicle system. Since it distinguishes whether a resource is recoverable when restoring the resource, it ensures that the previously cleared resources can be restored while avoiding the recovery of cached data of relatively low value. This saves device resources and network resources while minimizing the impact on the user's actual operations.

[0198] This application also provides a vehicle system upgrade device, please refer to Figure 5 , the vehicle system upgrade device comprises:

[0199] The detection module 10 is used to obtain at least one releasable resource when it is detected that the vehicle system needs to be upgraded and the available memory of the vehicle system does not meet the system upgrade requirements;
