[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0023] In the description of the present invention, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Moreover, the terms "first", "second", etc. are applicable to distinguishing similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0024] like Figure 1 As shown, it is a flow chart of an embodiment of the method for managing application version numbers of the present invention. The management method can, for example, centrally manage the version numbers of various applications in an operating system (such as an in-vehicle operating system) to facilitate applications or middleware to efficiently query the version numbers of other applications, to support the judgment of whether an application can be upgraded, or to support the management of synchronous upgrades between applications.

[0025] Specifically, the method for managing the version number of the application includes the following steps:

[0026] Step S102: Obtain the version numbers of the respective applications.

[0027] The version number of each application is pre-written in the code of each application, and the version number is updated as the application is updated. Thus, in step S102 , the version number of each application can be obtained by scanning the code of each application.

[0028] Specifically, a macro variable may be added to the code, and then the version number of the application may be defined in the macro variable. For example, the macro variable may be defined as: # macro variable start; constant = "version number"; # macro variable end. Thus, when obtaining the version number, step S102 may first identify the position of the macro variable start and the macro variable end from the application code, and then extract the data of the "version number" field from the constant to obtain the version number of the application.

[0029] Defining the application version number through macro variables helps to unify the format and specifications, making it easy to quickly and accurately locate the application version number.

[0030] In addition, by defining and updating the application version number through macro variables, the application developer only needs to focus on his own application development without considering the logic of subsequent integrators and system parties, which helps to reduce the difficulty of application development.

[0031] Step S104: Store the version number obtained in step S102 in the storage area.

[0032] After the version number of a certain application is extracted in step S102, the version number of the application may be written into a certain address segment of the storage area to achieve centralized storage and management of the version numbers of various applications.

[0033] Step S106: providing a version number management module, which is used to receive a query request from a queryer, and based on the received query request, query the version number of the target application from the storage area and feed it back to the queryer.

[0034] The inquirer may be, for example, an application or middleware in an operating system.

[0035] The version number management module has a query interface, which is an RTE (Run Time Environment) interface that complies with the Autosar (Automotive Open System Architecture) standard. The queryer can query the version number of the target application by calling or subscribing to the query interface. The RTE interface helps to achieve interconnection between the version number management module and other applications or middleware.

[0036] In addition, the query request may include, for example: a storage address acquisition request and a version number acquisition request. The version number management module acquires the storage address of the target application's version number based on the storage address acquisition request, and acquires the target application's version number based on the version number acquisition request and the acquired storage address.

[0037] In the embodiment of the present invention, the version number of each application is centrally managed through the version number management module, so that other applications or middleware can easily obtain the version number of the target application efficiently.

[0038] like Figure 2 FIG. 1 is a flow chart of an embodiment of an application upgrade method of the present invention. The application upgrade method comprises the following steps:

[0039] Step S202: The first application sends a query request to the version number management module to request to obtain the version number of the second application.

[0040] The first application and the second application have an association relationship. For example, the association relationship between the first application and the second application can be reflected in: when the first application is version 3.0, the second application cannot be lower than version 2.0. Therefore, when the first application is to be upgraded to version 3.0, if the version of the second application is lower than version 2.0, the first application cannot be upgraded. At this time, you can choose to prompt the user to upgrade the version of the second application to version 2.0 or above first, or control the first application and the second application to be upgraded synchronously.

[0041] Step S204: The first application receives the version number of the second application returned by the version number management module, wherein the version number of the second application and the version numbers of other applications are stored together in the storage area, and the version number of the second application is queried from the storage area by the version number management module based on the query request and fed back to the first application.

[0042] Specifically, for the content of the version number management module, please refer to Figure 1 The embodiments of the present invention are not described in detail here.

[0043] Step S206: The first application performs an upgrade operation according to the version number of the first application and the version number of the second application.

[0044] The first application can obtain its own version number in a manner that refers to an existing manner. In addition, the first application can determine whether to perform an upgrade based on its own version number and the version number of the second application, or upgrade the first application and the second application synchronously.

[0045] In this embodiment, through the version number management module, the first application can easily and efficiently obtain the version number of the second application, thereby realizing application upgrade management. In addition, obtaining the version number of other applications through the version number management module for upgrade management is only one of the many application scenarios of the version number management solution of the embodiment of the present invention, and is not a limitation of the version number management solution of the embodiment of the present invention.
