[0054] The specific embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0055] The current multi-screen cockpit is mainly realized by the interconnection of multiple systems and multiple terminals, which has a high development cost and a long development and maintenance cycle. The instability of the connection mode can affect the user's interactive experience. In order to achieve a better multi-screen environment, each automobile manufacturer introduces a one-machine multi-screen mode. However, in the one-machine multi-screen mode, it is not possible to build multiple application ecosystems on a single system, that is, it is not possible to realize the differentiated customization of application programs on different screens. In order to solve the above problems, the present disclosure provides an application preloading method.

[0056] FIG. 1 is a flowchart of an application preloading method according to an example embodiment of the present disclosure. The target device in the method can be a vehicle, and the method can be applied to a controller provided on the target device. As shown in FIG. 1, the method can include steps S101 to S104.

[0057] In step S101, the device type of the target device and the screen information of the target screen are obtained.

[0058] The target screen is one of the multiple display screens of the target device.

[0059] For example, the device type of the target device is various, and the device type can be the specific model of the device. Assuming that two different models of devices, 0x1 and 0x2, are included in the same project, the device type of the target device in the project can be 0x1 or 0x2. The device type of the target device can be pre-stored in the storage unit of the target device for calling when preloading the application.

[0060] For example, a plurality of display screens can be installed on the target device, the plurality of display screens are connected to the same controller, screen information can be reported by the display screens, the controller can acquire screen information of the plurality of display screens at the same time, and any one of the display screens can be determined as a target screen. The controller can also determine the number of target screens that report screen information, so as to facilitate subsequent determination of whether pre-installation of the plurality of target screens is completed.

[0061] In step S102, according to the screen information, a target application program required to be pre-installed by the target screen is determined.

[0062] For example, if the screen information includes information for indicating an application program to be pre-installed by the target screen, the application program indicated by the screen information can be determined as the target application program. For another example, a corresponding relationship between screen information and application programs can be constructed in advance, so that the application programs corresponding to the screen information of the current target screen can be determined by searching the corresponding relationship, and the application programs can be determined as the target application programs of the target screen.

[0063] According to the screen information, the target application program required to be pre-installed by the target screen reporting the screen information can be determined. Based on the screen information of the target screen a, the target application program required to be pre-installed by the target screen a can be determined; based on the screen information of the target screen b, the target application program required to be pre-installed by the target screen b can be determined. In this way, the controller can determine the application programs required to be pre-installed by different target screens connected thereto, and realize differentiated determination of the application programs of different display screens.

[0064] In step S103, according to the device type and the screen information, a target installation path of the target application program is determined.

[0065] In step S104, the target application program is installed in the target installation path.

[0066] For example, an identifier corresponding to the device type, information corresponding to the screen information, and an identifier corresponding to the set of target application programs can be determined, and the target installation path can be determined based on the identifiers, for example, the identifiers can be filled into a preset path template to obtain the target installation path. The preset path template can be: System / custom / priv-app / identifier corresponding to the device type / identifier corresponding to the screen information / identifier corresponding to the set of target application programs.

[0067] In this way, after determining the application programs respectively required to be pre-installed by different target screens, the target installation path can be quickly and accurately determined according to the device type and the screen information, the target application programs of the target screen are installed into the corresponding target installation path, and the application ecology of each target screen is constructed, thereby realizing the differentiated customization of the application programs of different screens in the one-machine multi-screen mode and improving the use experience of the user.

[0068] In the technical solution, the device type of the target device and the screen information of the target screen are obtained, the target screen is one of the multiple display screens of the target device, the target application programs required to be pre-installed by the target screen are determined according to the screen information, the target installation path of the target application programs is determined according to the device type and the screen information, and the target application programs are installed in the target installation path. In this way, the differentiated installation of the application programs of different screens in the one-machine multi-screen mode can be realized, the construction of the multi-screen multi-application ecology in the single system can be realized, the multi-screen display can be more personalized, and the use experience of the user can be improved.

[0069] In an optional embodiment, the screen information can include the screen type.

[0070] For example, multiple display screens of different types can be installed in the target device, and the screen type can be information used to represent the specific model of the display screen. Correspondingly, in the first embodiment, in step S102, steps S201 and S202 shown in FIG. 2 can be included.

[0071] In step S201, according to the integrated pre-installation structure, the target pre-installed application program set corresponding to the device type of the target device and the screen type of the target screen is determined.

[0072] In step S202, the target application program is determined according to the target pre-installed application program set.

[0073] The integrated pre-installation structure is a tree structure constructed in advance according to the correspondence among the device type, the screen type, and the pre-installed application program set. For example, the device type, the screen type, and the pre-installed application program set can be determined by the project type and the product definition, and the corresponding information table can be constructed, the information table can include the application program set corresponding to each device type and the application program set corresponding to each screen type, and the screen type corresponding to each type of device. In this way, the correspondence among the device type, the screen type, and the pre-installed application program set can be determined through the information table. The tree structure constructed based on the correspondence among the three, that is, the integrated pre-installation structure.

[0074] The tree structure can be as shown in FIG. 3. The first-level node is used to represent the device type, the second-level node is used to represent the screen type, and the third-level node is used to represent the set of pre-installed applications corresponding to the device type and the screen type represented by the upper-level nodes. The upper-level nodes include the second-level node to which the third-level node is connected and the first-level node connected to the second-level node to which the third-level node is connected. As shown in FIG. 3, the device type includes 0x1 and 0x2, the screen type includes A, B, and C, and the set of pre-installed applications corresponding to the screen type includes L1, L2, L3, and L4. In FIG. 2, if the obtained device type is 0x2 and the screen type of the target screen is C, the corresponding set of target pre-installed applications L4 can be determined. In this way, the set of pre-installed applications corresponding to the device type and the screen type, which is predefined, can be quickly and accurately determined based on the integrated pre-installed structure, and the multi-screen regionalization function interface display can be implemented.

[0075] The pre-installed applications can be the applications that need to be displayed differently in different screens and do not belong to the basic configuration applications of the package manager service (Package Manager Service). The applications that do not need to be displayed differently in different screens and the basic configuration applications of the package manager service can be installed before the device type of the target device and the screen information of the target screen are obtained.

[0076] As shown in FIG. 3, if the obtained device type is 0x1 and the screen type of the target screen is A, the corresponding set of target pre-installed applications L1 and L2 can be determined. At this time, the set of target applications can be determined from L1 and L2 in combination with the device configuration information of the target device. In an optional embodiment, the set of pre-installed applications is associated with the device configuration information, and the device configuration information can include the configuration level of the device, such as high configuration, medium configuration, and low configuration. Correspondingly, in step S202, determining the target application according to the set of target pre-installed applications can include steps S2021 and S2022 as shown in FIG. 4.

[0077] In step S2021, the device configuration information of the target device is obtained.

[0078] In step S2022, the pre-installed applications in the set of target pre-installed applications associated with the device configuration information of the target device are determined as the target applications.

[0079] For example, the determined L1 and L2 are associated with the device configuration information, for example, the device configuration information associated with L1 indicates that the configuration level of the device is high, and if the device configuration information of the target device indicates that the configuration level of the target device is high, L1 is determined as the set of target applications, and the applications in L1 are determined as the target applications. In this way, the target applications that can adapt to the specific device configuration information of the target device can be determined, and the accuracy of the determined target applications is improved.

[0080] In an optional embodiment, the application preloading method provided by the present disclosure can further include:

[0081] In response to the change configuration information for changing the set of preloaded applications, the set of preloaded applications is updated according to the change configuration information to obtain an updated set of preloaded applications.

[0082] For example, the change configuration information can be used to indicate that the application in L4 of the C screen under 0x2 needs to be specially processed and installed, and the set of preloaded applications can be updated based on the change configuration information to obtain a new set of preloaded applications. For example, the change configuration information indicates that the application 4 in L4 of the C screen under 0x2 is not preloaded, and the application 4 in L4 is deleted to form a new set L4-1. The change configuration information can be pre-stored in the target screen or input into the target screen by the user in real time, and the change configuration information can be sent to the controller by the target screen. In this way, the flexibility of the determined target applications can be improved through the processing of the change configuration information.

[0083] Through the integrated preloading structure described above, the corresponding application ecosystem can be dynamically loaded in combination with the device type of the target device and the screen information of the target screen, so that the vehicle-mounted system integration is more lightweight, and the user's interactive experience is improved. The scheme has strong compatibility, is not limited by the platform, has strong expansibility, and can realize the display of diversified functions and differentiated interfaces in the one-machine-multiple-screen mode.

[0084] In an optional embodiment, the screen information can include screen preloaded application information for indicating the applications to be preloaded by the target screen. That is, the target screen can directly report the applications it wants to install to the controller through the screen preloaded application information. Correspondingly, in the second embodiment, step S102 can include step S301 as shown in FIG. 5.

[0085] In step S301, the target applications required to be preloaded by the target screen are determined according to the screen preloaded application information.

[0086] For example, the application indicated by the screen pre-installed application information can be determined as the target application required to be pre-installed by the target screen. In this way, without pre-constructing the integrated pre-install structure and without pre-storing the correspondence between the screen type and the application at the controller side, the controller can directly determine the target application required to be pre-installed by the target screen through the analysis of the screen pre-installed application information, and the application pre-install efficiency is improved.

[0087] In order to ensure the normal use of the target screen of the target device, it is often necessary to ensure that the basic application of the target screen is installed in the target screen, so as to ensure that the ecosystem under the target screen can be normally used. The basic application refers to the indispensable application in the target screen of the target device. Therefore, in order to avoid the abnormal ecosystem under the target screen due to the lack of the basic application, the target application can be determined in combination with the screen pre-installed application information and the basic application. Specifically, the target application required to be pre-installed by the target screen can be determined according to the screen pre-installed application information through steps S3011 to S3013 as shown in FIG. 6:

[0088] In step S3011, the application to be pre-installed by the target screen is determined according to the screen pre-installed application information.

[0089] For example, the application indicated by the screen pre-installed application information can be determined as the target application required to be pre-installed by the target screen. In this way, without pre-constructing the integrated pre-install structure and without pre-storing the correspondence between the screen type and the application at the controller side, the controller can directly determine the target application required to be pre-installed by the target screen through the analysis of the screen pre-installed application information, and the application pre-install efficiency is improved.

[0090] In step S3012, the basic application corresponding to the target screen is determined.

[0091] The basic application is an indispensable application in the target screen of the target device. The basic application can be pre-set.

[0092] In step S3013, the target application is determined according to the application to be pre-installed by the target screen and the basic application corresponding to the target screen.

[0093] For example, the target application includes each application in the union set of the application to be pre-installed by the target screen and the basic application corresponding to the target screen. That is, if the application to be pre-installed by the target screen includes the basic application corresponding to the target screen, the application to be pre-installed by the target screen can be determined as the target application; if the application to be pre-installed by the target screen lacks any basic application, the application to be pre-installed by the target screen and the missing basic application can be determined as the target application. In this way, the flexibility of the pre-installed application can be ensured, and the reliability of the pre-installed application can be ensured, and the lack of the basic application can be avoided.

[0094] For another example, in the case that any basic application is missing in the application to be preinstalled in the target screen, the target application can be determined by the method in the first embodiment described above in combination with the integrated preinstallation structure. FIG. 7 is a flowchart of an application preinstallation method provided by an exemplary embodiment of the present disclosure, from which the process of determining the target application according to the application to be preinstalled in the target screen and the basic application corresponding to the target screen can be more clearly understood. As shown in FIG. 7, the method can include step S3014, step S3015, step S201, step S2021 and step S2022 in step S3013.

[0095] In step S3014, it is determined whether any basic application is missing in the application to be preinstalled in the target screen. If yes, step S201 is performed; if no, step S3015 is performed.

[0096] In step S3015, the application to be preinstalled in the target screen is determined as the target application.

[0097] In step S201, according to the integrated preinstallation structure, the target preinstallation application set corresponding to the device type of the target device and the screen type of the target screen is determined.

[0098] In step S2021, the device configuration information of the target device is acquired.

[0099] In step S2022, the preinstallation application in the target preinstallation application set associated with the device configuration information of the target device is determined as the target application.

[0100] In this way, the preinstallation application flexibility can be ensured, the absence of the basic application can be avoided, the constructed ecological system under the target screen is normal, has better compatibility, the personalized and functional application preinstallation is realized, the one-machine multi-screen mode is more intelligent, and the user experience is improved.

[0101] It is worth noting that in FIG. 7, in the case of determining whether any basic application is missing in the application to be preinstalled in the target screen, in the process of performing step S2022, when the preinstallation application in the target preinstallation application set associated with the device configuration information of the target device is determined, the preinstallation application set can also be updated according to the change configuration information for changing the preinstallation application set, to obtain an updated preinstallation application set, so as to determine the application in the updated preinstallation application set as the target application. Wherein, because the change configuration information does not necessarily have universality, when the new preinstallation application set is obtained, the integrated preinstallation structure itself can not be updated.

[0102] Further, the specific implementation of the above step S201, step S2021 and step S2022 has been described in detail above, and the repeated content will not be repeated here.

[0103] In an optional embodiment, in step S103, determining the target installation path of the target application according to the device type and the screen information can include:

[0104] According to the device type of the target device, the screen type of the target screen and the set of target applications, determining target path information, wherein the target path information includes a first identifier corresponding to the device type of the target device, a second identifier corresponding to the screen type of the target screen and a third identifier corresponding to the set of target applications;

[0105] According to the target path information, determining the target installation path.

[0106] For example, if the target application is determined by the integrated pre-install structure, and the set of target applications is consistent with the content in the set of target pre-install applications in the integrated pre-install structure corresponding to the device type of the target device and the screen type of the target screen, the identifier of the set of target pre-install applications can be determined as the third identifier corresponding to the set of target applications.

[0107] If the target application is determined by the integrated pre-install structure, but the set of target applications is inconsistent with the content in the set of target pre-install applications in the integrated pre-install structure corresponding to the device type of the target device and the screen type of the target screen, i.e. the set of target pre-install applications is updated by the aforementioned change configuration information, the identifier of the updated set will also change, for example, the identifier of the set of target pre-install applications is L4, and the identifier of the updated set can be changed to L4-1. The identifier of the updated set can be determined as the third identifier.

[0108] If the target application is not determined by the integrated pre-install structure, the third identifier corresponding to the set of target applications can be generated by itself.

[0109] The target path information can include the first identifier, the second identifier and the third identifier. Taking the device type of the target device as 0x1, the screen type as A and the set of target applications as L1 as an example, 0x1 can be determined as the first identifier, A can be determined as the second identifier, and L1 can be determined as the third identifier, and the target path information 0x1 / A / L1 can be determined. The target path information and the path prefix information can be combined to obtain the target installation path, wherein the path prefix information can be System / custom / priv-app / , and the obtained target installation path can be System / custom / priv-app / 0x1 / A / L1.

[0110] Thus, the target installation path can be determined simply and quickly, and the target application program can be installed in the target installation path, and different target screens can be constructed with respective application ecologies, and the application programs of different screens can be customized differently, and the user experience can be improved.

[0111] Based on the same inventive concept, the disclosure also provides an application preloading device. FIG. 8 is a block diagram of an application preloading device 500 according to an example embodiment of the disclosure. Referring to FIG. 8, the application preloading device 500 can include:
