Automotive Electronics Embedded Sotfware Development Application Sotfware Research And Analysis

At present, China’s auto electronic technology is still relatively backward, more than70%of the domestic market is occupied by foreign enterprise, the foreign capital enterprisealso formed a technical barriers in engine electronic core areas and monopolized theChinese market. How to break the deformity pattern of domestic auto electronic marketand grasp the independent intellectual property rights of the automobile electronic keytechnology currently become a pressing demand.Auto electronic software technology is the core of the automobile electronictechnology, but is also the highest part of the technical content. The quality of the softwaredirectly determine the auto electronic products’ quality. However, programmers still takethe way of hand writing code in automobile electronic software development process, it isexposed that the code quality is not reliable and later will produce a lot of unnecessarytesting the disadvantages of cost completely.As the auto electronic software control algorithms are nearly the same, in order toprovide auto electronic software reusability, a widely accepted standard of vehicleoperation system has been put forward, OSEK/VDX. Software technology based on themodel and the code automatic generation [2], is an effective way of solving the aboveproblems. First of all, it not only guarantees the quality of the code, but also reduces theadditional testing costs. Secondly, automatically generated code makes the model, code andcode generation report to be consistent. Moreover, by adding support OSEK standardmodule in the model, software reusability and portability are also significantly enhanced.OSEK makes comprehensive definition for auto electronic control software developmentfrom realtime operating system, communication and network management. Adopting autoelectronic software which conforms OSEK standard could improve the product code reuserate, reduce the development cost, shorten the product development cycle.This topic integrates each tool through studying auto electronic softwaredevelopment model and code automatic generating tool, and using the LambdaTOOLdevelopment environment, in which integrate with OSDeltaOSEK of OSEK standard,itprovides the necessary function support event driven control system; Simulink modeling environment, it is a model based design tools, completing linear system, nonlinear systemmodeling through the models; RTW EmbeddedCoder, it is the expansion of RTW (Real.Time Workshop) products, increasing important software engineering contents inconfiguration complex embedded system. Automatic code generation tool, achieved asoftware development platform for auto electronics, so as to shorten the auto electronicsoftware product development cycle, reduce the cost of development, improve thedevelopment efficiency, and make the software product has good maintainability andreusability.The AUTOSAR framework is good for vehicle electronic system software exchangeand update, and provides a foundation for vehicle electronics and software system efficientmanagement,which is more and more complex. In addition, AUTOSAR ensures productand service quality at the same time, improves the cost efficiency. Currently, more andmore manufacturers join AUTOSAR organization, the development of products is alsoproud of being able to support AUTOSAR standard, AUTOSAR has actually become autoelectronic development standard, and will certainly become automobile electronic softwaredevelopment trend in the future.
