Research On The Open Automotive Electronic Software Architecture Based On "Underlying Software That Can Be Automatically Configured"

At present,the automotive electronics technology develops rapidly,but OEMs are still weak in the development of automotive electronic software architecture.The development of automotive electronic software mainly depends on suppliers,and the software architecture has no standard definition.In order to provide a standardized software interface and software architecture,the open automotive electronic software architecture(OSEK)and AUTOSAR(AUTOSAR)are presented.Through investigation and analysis of several current common automotive electronic software development modes and software architecture under different development modes,this paper proposes two major problems in automotive electronic software development,namely,the difficulty of low-level software development and unreusable,and the unclear software architecture of application layer.Aiming at these two problems,this paper provides an optimized open automotive electronic software architecture,which has achieved improvement directions in two aspects :(1)it proposes an underlying software that can be automatically configured,which solves the problem that the underlying software is difficult to develop and cannot be reused;(2)A "three-layer architecture" application-layer software architecture is proposed,which further reduces the coupling degree with the underlying software and increases the portability of application-layer software.This paper uses the above optimized automotive electronic software architecture to develop the on-board gateway controller.Based on the development process of the underlying software which can be automatically configured,the development of the underlying software is separated from the specific software requirements.The application layer software architecture is developed according to the thought of "three-layer architecture".By verifying whether the underlying software independently developed can support the system requirements of the gateway controller,the universality of the underlying software that can be automatically configured is illustrated.Through the migration and integration of network management module,the portability and tailoring of application layer software of "three-layer architecture" are illustrated.The development and integration process of on-board gateway controller verifies the feasibility of the underlying software of "automatic configuration",explains the universality of the underlying software,and verifies that the application software of "three-layer architecture" is conducive to the further stratification of the application layer software and improves the portability and tailoring of the application layer software.
