The core of this embodiment is that, as shown in fig. 3, the vehicle-mounted application upgrading system specifically includes: central gateway device 100, domain master control device 200, slave electronic control unit ECU 300; the central gateway device 100 is in communication connection with the domain master control device 200 and is used for exchanging and transmitting vehicle-mounted application upgrading data; the domain master control device 200 is configured to acquire the vehicle-mounted application installation package through the central gateway device 100, send the vehicle-mounted application installation package to the slave ECU300 corresponding to the vehicle-mounted application installation package, and perform interface adaptation according to information of the vehicle-mounted application installation package; and the slave ECU300 is configured to respond to the vehicle-mounted application installation instruction issued by the domain master control device, and complete the upgrade management of the vehicle-mounted applications in the domain.
In this embodiment, the domain master control device 200 acquires the corresponding vehicle-mounted application upgrade package through the central gateway 100 device, and sends the corresponding vehicle-mounted application upgrade package to the corresponding slave ECU300, and meanwhile, performs interface adaptation on the vehicle-mounted application installation package according to the information of the vehicle-mounted application installation package, so that ECUs constructed in various OS systems can manage upgrade services in a unified and general manner, thereby implementing online cross-system synchronous upgrade of vehicle-mounted applications; in the embodiment of the invention, the interaction is only carried out between the upper domain master control equipment and the vehicle-mounted application service platform, so that the frequent interaction between each ECU and the vehicle-mounted application platform is reduced, the uniform processing of vehicle-mounted upgrading management services is realized, the concurrent pressure in the vehicle-mounted application upgrading process is reduced, the whole vehicle services are more orderly and efficient, and the whole vehicle resources are utilized to the maximum extent to realize the upgrading of more ECU applications.
The following describes the structural components of the vehicle-mounted application upgrading system in detail, and the following is only provided for the convenience of understanding, and is not necessary for implementing the present solution.
In one example, the domain master device 200 in this embodiment includes an in-vehicle application upgrade management module 201 and a first communication module 202.
The vehicle-mounted application upgrade management module 201 is configured to receive vehicle-mounted application update information forwarded by the central gateway device 100, customize an update policy according to the vehicle-mounted application update information and intra-domain vehicle-mounted application basic information, generate an update request, and acquire a vehicle-mounted application installation package, where the update request includes a full upgrade package request and a differential upgrade package request, and the vehicle-mounted application installation package carries an identity identifier corresponding to a slave ECU to be upgraded.

Specifically, the vehicle-mounted application upgrade management module 201 receives vehicle-mounted application update information transmitted from the central gateway device 100 by HTTP protocol communication, and performs management policy analysis and update prompting for each vehicle-mounted application in the slave ECU according to the vehicle-mounted application update information, where the vehicle-mounted application update information includes an updatable vehicle-mounted application list, a corresponding management configuration item, and the like. Then, the vehicle-mounted application upgrade management module 201 sends an instruction for inquiring the basic information of each vehicle-mounted application to each slave ECU300 in the domain through the first communication module 202, the slave ECU300 responds to the inquiry instruction and feeds back the collected basic information of each vehicle-mounted application to the first communication module 202, and the first communication module 202 transmits the basic information of the vehicle-mounted application on the slave ECU300 to the vehicle-mounted application upgrade management module 201, wherein the basic information of the vehicle-mounted application comprises the version number of the vehicle-mounted application. The vehicle-mounted application upgrade management module 201 customizes an update policy according to the received vehicle-mounted application basic information and vehicle-mounted application update information, for example, by comparing the version number of the vehicle-mounted application, if the version number of the vehicle-mounted application that can be updated is higher than the version number of the installed vehicle-mounted application, it is determined that the vehicle-mounted application needs to be updated, and the update policy is listed in an update request list; meanwhile, for different to-be-updated vehicle applications, the vehicle application upgrade management module 201 may determine a mode of acquiring the upgrade package, such as requesting to download a full upgrade package or a differential upgrade package. After the vehicle-mounted application upgrade management module 201 obtains the vehicle-mounted application installation packages, the identity information corresponding to the slave ECU300 is attached to each vehicle-mounted application installation package according to the information of each vehicle-mounted application installation package, and the vehicle-mounted application installation packages are issued to the addresses corresponding to the slave ECUs to be upgraded.
The vehicle-mounted application upgrading management module determines the applications needing to be upgraded in the slave ECU in the domain according to the vehicle-mounted application basic information and the vehicle-mounted application updating information, determines whether the installation packages needing to be acquired by the corresponding upgraded applications are full upgrading packages or differential upgrading packages, customizes upgrading strategies in a unified mode, generates upgrading requests, further realizes comprehensive and systematic upgrading management of the slave ECU in the domain, and realizes upgrading with higher efficiency; in addition, the vehicle-mounted application installation package carries the identity corresponding to the slave ECU to be upgraded, so that the domain master control device can issue the vehicle-mounted application upgrade package to the corresponding slave ECU, and the order and the high efficiency of the vehicle-mounted application upgrade service are further ensured.
In one example, the slave ECU300 includes a second communication module 301, a slave adaptation layer 302.
And the second communication module 301 is configured to perform interaction and transmission of the vehicle-mounted application upgrade data with the domain master control module 200.
Specifically, the second communication module 301 interacts with the first communication module 202 in the domain master control device 200, and the slave ECU300 transmits the collected basic information of the vehicle-mounted application to the domain master control device 200 through the second communication module 301, and receives the upgrade installation package of the vehicle-mounted application issued by the domain master control device 200. Here, a second communication module is provided in the slave ECU to communicate with the domain master module, so as to facilitate the unified management of the slave ECUs by the domain master module and further reduce the complexity of communication between the ECUs.
The slave adaptation layer 302 is configured to respond to an interface adaptation instruction issued by the domain master control device 200, perform interface adaptation according to the information of the vehicle-mounted application installation package, and complete upgrade management of the vehicle-mounted application. Specifically, after the vehicle-mounted application installation package is distributed to the correct slave ECU to be upgraded, in order to implement the installation of the broken OS system, the slave adaptation layer responds to the interface adaptation instruction issued by the domain master device 200, that is, the domain master device calls the slave adaptation layer 302 on the slave ECU300, and implements management tasks such as the installation upgrade of each vehicle-mounted application on the slave ECU 300.
In practical application, the slave adaptation layer 302 is a bottom-layer architecture abstract adaptation layer interacting with different OSs of the ECU, and abstracts vehicle-mounted application management of different operating systems into middleware with a uniform interface, so that the vehicle-mounted application has independence and neutrality. Specific functions from the adaptation layer include: (1) installation: calling/realizing a bottom-layer universal installation interface, and installing the downloaded vehicle-mounted application; (2) unloading: calling/realizing a bottom-layer universal installation interface, and unloading the installed vehicle-mounted application; (3) starting: the method comprises the steps of self-starting and hand starting, and calling an application starting interface to start the installed vehicle-mounted application according to setting; (4) pausing: calling an application stopping interface to stop the corresponding vehicle-mounted application according to an external instruction; (5) and (3) permission configuration: calling an application authority configuration interface to configure the vehicle-mounted application authority, such as the authority of accessing a certain file, the authority of accessing a certain interface and the like; (6) starting configuration: calling an application starting parameter configuration interface to configure the vehicle-mounted application starting item, such as manual starting and self-starting during starting; (7) network configuration: calling an application network parameter configuration interface to configure the vehicle-mounted application network, wherein the configuration comprises APN selection and network link functions of the vehicle-mounted application; (8) obtaining an application list: the in-vehicle application list acquisition interface is called to acquire application list information corresponding to the installed application from the ECU apparatus. In addition, the running time of a certain vehicle-mounted application can be acquired so as to know the use frequency of the vehicle-mounted application by a user; or feeding the log of the vehicle-mounted application back to the domain main control equipment to be uploaded to an external application platform. In conclusion, the slave adaptation layer can realize management of the vehicle-mounted application among different operating systems, and solves the problem that application upgrading is only limited to android equipment, so that the vehicle-mounted application on the LINUX and QNX system equipment can also realize upgrading, and parallel upgrading of the vehicle-mounted application can be realized even among the slave ECUs corresponding to different operating systems through unified management of the domain master control module.
In the first embodiment of the present invention, it is easy to find that the domain master control device interacts with each slave ECU through the first communication unit and the second communication unit in this embodiment, so that the domain master control device is convenient for unified upgrade management, and the complexity of communication between the ECUs is reduced; and a slave adaptation layer is arranged in the slave ECU to realize the upgrading of the vehicle-mounted application under the cross-OS condition, even the parallel upgrading of the vehicle-mounted application can be realized among different operating systems, and the whole vehicle service is more orderly and efficient.
A second embodiment of the present invention relates to a vehicle-mounted application upgrade system. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: in a second embodiment of the present invention, the domain master control device further includes a master adaptation layer, the slave ECU further includes an HMI module, and the attribute of the vehicle-mounted data, the security of the vehicle-mounted application, and the diversity light of the vehicle-mounted device are fully considered, and a vehicle-mounted application service platform is provided in combination with the planning of the vehicle-mounted interface by the vehicle enterprise.
Specifically, as shown in fig. 4, the vehicle-mounted application upgrading system provided by the second embodiment includes: a central gateway device 100, a domain master device 200, a slave ECU300-1, a slave ECU300-2, and an in-vehicle application service platform 400.
The central gateway device 100 is in communication connection with the vehicle-mounted application service platform 400 and the domain master control device 200, and is configured to implement exchange and transmission of vehicle-mounted application upgrade data between the vehicle-mounted application service platform 400 and the domain master control device 200. In practical applications, the central gateway device 100 may use a 4G communication module to implement communication connection.
The domain master control device 200 includes an in-vehicle upgrade management module 201, a first communication module 202, and a main adaptation layer 203. Here, the functions of the vehicle-mounted upgrade management module 201 and the first communication module 202 are similar to those of the vehicle-mounted upgrade management module 201 and the first communication module 202 mentioned in the first embodiment, and are not described again.
And the main adaptation layer 203 is used for carrying out interface adaptation according to the identity identification to finish the upgrading management of the vehicle-mounted application on the slave ECU. Here, the main adaptation layer 203 is consistent with the function of the slave adaptation layer mentioned in the first embodiment, but because the main adaptation layer is located in the domain master control device 200, the main adaptation layer performs interface adaptation according to the identity carried by the vehicle-mounted application and corresponding to the slave ECU to be upgraded, so as to abstract the vehicle-mounted application into a middleware with a uniform interface, thereby ensuring upgrade management of the vehicle-mounted application in the slave ECUs corresponding to different OS systems.
Both slave ECU1(300-1) and slave ECU2(300-2) contain a second communication unit and a slave adapter layer, respectively. Here, the functions of the second communication unit and the slave adaptation layer are similar to those of the second communication unit 201 and the slave adaptation layer 202 mentioned in the first embodiment, and are not described in detail. The slave ECU2(300-2) further includes an HMI module, and the domain master control device 200 is further configured to control the HMI module 303-2 to provide an upgrade interaction interface through the first communication module and the second communication module, so as to indirectly control the HMI module across domains through the domain master control device 200, implement interface display and interaction in the vehicle-mounted application upgrade process, and improve the vehicle use experience of the user.
In practical application, the HMI module is a human-computer interaction page which is divided into a display layer and a data processing layer. The display layer is a medium for information interaction of the vehicle-mounted application upgrade management 201 module of the vehicle owner and the vehicle domain, and comprises the following display contents: (1) starting a loading page; (2) first page: for integrally displaying installable or updateable application information; (3) page details page: the vehicle-mounted application display system is used for displaying application information and enabling a vehicle owner to know functions and functions of certain vehicle-mounted application; (4) application rights management page: the authority control button is used for displaying the authority information of the application, and the owner can click the authority control button to open or close certain authorities; (5) application management page: for presenting currently ongoing activities (e.g., downloading, installing, etc.), updateable applications, or all in-vehicle applications, and providing corresponding uninstall buttons; (6) a setup page for displaying whether the application has an updateable version, configurable information (e.g., whether to delete APK after installation, whether to quiesce installation, etc.). Aiming at the interface, the types and the attributes of the view of the HMI are further defined, and the types specifically comprise the following types: the Image View displays any Image, such as an icon (attribute of a display picture), a Text View displaying Text to a user (attribute of a display Text), a Button provided by a Toggle Button to the user (Button attribute), a View in which the Text Input Edit Text can be edited (Text editing attribute), and a List View describing List options to be selected by the user (selection attribute of the List). The view types standardize basic attributes (such as clickable, editable and startable) of vehicle-mounted application interfaces on different slave ECUs and different OS systems, avoid complex interface matching processing mechanisms of various applications, and simplify the interface logic processing process.
In one example, the RPC framework may be employed when either the second communication unit 301-1 in the slave ECU1(300-1) or the second communication unit 301-2 in the slave ECU2(300-2) communicates with the first communication module 202 in the domain master device 200. As shown in fig. 5: a complete RPC architecture comprises four core components, namely a Client, a Server, a Client Stub and a Server Stub, wherein the Stub can be understood as a Stub. The Client is a calling party of the service; the server Servr is a true service provider. The client stub is used for storing address information of the server, packaging request parameters of the client into network information, and then remotely sending the network information to the server through a network; and the server stub is used for receiving the message sent by the client, unpacking the message and calling a local method. In the vehicle-mounted application upgrading system according to the embodiment, the domain master control device 200 is an information transfer center, and information such as messages and instructions of each slave ECU must be submitted to the first communication unit 202 on the domain master control device 200 through the second communication unit, and then are interacted with the vehicle-mounted application upgrading management module 201 to be analyzed, and finally are transmitted to the corresponding slave ECU by the vehicle-mounted application management module 201 to be executed. For example, when the vehicle-mounted application on a certain ECU has UI display attributes, that is, when an interface needs to be displayed, the display requirement is submitted to the vehicle-mounted application upgrade management module 201 through the second communication module and the first communication module for logic processing, and the generated next step instruction and the like are transmitted to the slave ECU having the HMI module through the second communication module and the first communication module, so as to be displayed in the HMI module.
And the vehicle-mounted application service platform 400 is configured to synchronize vehicle-mounted application upgrade information to the domain master control device 200, respond to a vehicle-mounted application upgrade request sent by the domain master control device 200, and provide a vehicle-mounted application installation package corresponding to the upgrade request. The method specifically comprises the following steps: a vehicle model domain management module 401, an application center module 401, and a user management module 403.
And a vehicle type domain management module 401, configured to record or synchronize vehicle type information and domain-associated vehicle terminal information. Specifically, the method comprises the following steps: the information of vehicle types and vehicles corresponding to the OEM, the information of different domains under each vehicle type, the terminal and version related to the domains, the registration time, the PIN and the like can be recorded or synchronized. When the vehicle is activated and registered, the platform can synchronously compare the information with the terminal and also can send an abnormal alarm, so that the abnormal vehicle can be conveniently and independently treated.
And the application center module 401 is used for uploading and managing the vehicle-mounted application installation package, and performing management configuration of upgrading information according to the vehicle-mounted upgrading request. Specifically, the functions of application icons, names, types, supporting software systems, version numbers, application states, creation time, application screenshots, application installation packages, descriptions, application security levels and the like can be shelved and managed; the domain and the terminal equipment to which each application belongs, a system and a version which can be matched, and an installation or upgrading mode can be configured in the application strategy, and the vehicle precondition judgment is selected according to different safety levels of the application. In addition, in order to reduce the calculation amount of the vehicle-mounted application service platform, the application center module determines a differential or full upgrading mode. That is, the application upgrade package also supports differential processing on the vehicle-mounted application platform, and a smaller upgrade package is released to the vehicle, so that the domain master control device 200 can realize more efficient upgrade according to the corresponding differential restoration program. The application aiming at the configuration completion strategy can be tested and audited on the platform, and the passed application can be put on shelf and synchronously pushed to the application market of the user terminal.
In practical application, for example, need to put on a shelf the APP of a certain control headlight, input application basic information, upload APP installation package earlier, then the controller system version that the configuration strategy needs relevant motorcycle type, car territory, corresponding car light controller and support, because of headlight APP is relevant to driving safety, therefore the safety class is high, needs the configuration installation precondition to judge: the driving state is parking, the vehicle speed is 0 and the like. The differential management can support the application packages of the similar 2 versions to carry out differential upgrading, the downloading and upgrading time can be saved for the larger application upgrading package, and the upgrading efficiency is improved. And selecting a test vehicle meeting the conditions for application and pushing by the platform, testing whether the vehicle-end lamp controller can be normally installed and upgraded, approving and putting on the shelf if the test is passed, and synchronously pushing the target vehicle type and the vehicle.
And the user management module 403 is configured to record vehicle end user information.

step 601: and receiving the vehicle-mounted application information and the vehicle-mounted application installation package.
Specifically, the domain master control device receives vehicle-mounted application update information downloaded by a vehicle-mounted application service platform by adopting HTTP protocol communication, and then executes management strategy analysis and update prompt on vehicle-mounted applications in each slave ECU according to the vehicle-mounted application update information, wherein the vehicle-mounted application update information comprises an updatable vehicle-mounted application list, corresponding management configuration items and the like. And then, the domain master control equipment sends an instruction for inquiring the basic information of each vehicle-mounted application to each slave ECU in the domain, the slave ECU responds to the inquiry instruction and uploads the collected basic information of each vehicle-mounted application to the domain master control equipment in a feedback mode, wherein the basic information of each vehicle-mounted application comprises the version number of the vehicle-mounted application. The domain master control equipment customizes an updating strategy according to the received vehicle-mounted application basic information and vehicle-mounted application updating information, for example, by comparing the version number of the vehicle-mounted application, if the version number of the vehicle-mounted application which can be updated is higher than the version number of the installed vehicle-mounted application, the vehicle-mounted application is determined to be updated and listed in an updating request list; meanwhile, for different to-be-updated vehicle-mounted applications, the domain master control device may determine a mode of acquiring the upgrade package, such as a request for downloading a full upgrade package or a differential upgrade package.
