Embodiment

[0030] image 3 It is a specific implementation principle block diagram of the virtual function bus designer oriented to automotive electronics in the present invention.

[0031] In this example, if figure 1 As shown, the automotive electronics-oriented virtual function bus designer of the present invention includes: a project resource management module 1, a graphic design module 2, an attribute editing module 3, a parts library management module 4, and a description information import and export module 5.

[0032]In this embodiment, the graphical design module 2 is used to provide graphical design of components, component sets, ports, interfaces, and data types in compliance with the AUTOSAR standard, and to verify the rationality of design and assembly according to the standard. In addition, this module supports the graphics copy, paste, drag and drop, and zoom functions of conventional graphics drawing tools.

[0033] In this embodiment, the attribute editing function of ...

Abstract

The invention discloses an automotive electronics oriented virtual functional bus designer. A construction member, a construction member set, a port, an interface, a connection and a data type contained in an application are generated into description information in a graph designing module and an attribute editing module, and the description information is stored into a library file by virtue of a part library management module. During the virtual functional bus design, the description information is read out and then is displayed and edited to obtain the description information and relations of the construction member, the construction member set, the port, the interface, the connection and the data type contained by the current application, and the obtained description information and the relations are stored into a project file or form a description file according with the AUTOSAR (automotive open system architecture) standard by import of the description information and export of an export module. A user can voluntarily design the construction member, the construction member set, the port, the interface, the connection and the data type contained by the application, and the application is stored in the project file, thus the automotive electronics oriented virtual functional bus designer can be applicable to various construction members, construction member sets, ports, interfaces, connections and data types and has good generality and reusability.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics embedded software development, and more specifically relates to a virtual function bus designer for automotive electronics. Background technique [0002] Applications in the automotive field have undergone dramatic changes in recent years. The emergence of more and more new applications not only brings new opportunities, but also brings new challenges to automotive software developers in research and development. Today's cars, especially luxury cars, have very high hardware and software complexity. For example, there can be as many as 70 electronic control units (Electronic Control Unit, ECU) and 10 different types of control buses in one car. Automotive software is no longer a simple control program on an electronic controller, and software development is faced with a distributed, heterogeneous embedded environment. [0003] On the other hand, with the increasingly advanced and c...
