Research On The Data Management System In Automotive Control Systems

With the development of automotive electronics industry, the functional scope of automotive electronic control system are growing significantly fast, the amount of data that needs to be managed is increasing dramatically. In today’s systems, the data is handled in an hoc fashion, using internal data structures, it causes the system to a high degree of data redundancy, and it does not satisfy the increasing demand of the efficient data management in automotive control systems. Using a general-purpose off the shelf DBMS is not feasible, thereby we need to develop a particular DMS, which could provide a uniform and efficient way to manage data in vehicle.In this paper we research the characteristic of the data management in automotive control systems, utilize the benefits of component-based software development(CBSD) and aspect-oriented software development (AOSD), design a configurable and hybrid VDMS for resource-constrained automotive control systems. And we referring to AUTOSAR standards, analyze AUTOSAR software-architecture, AUTOSAR methodology, and VDMS software-components. After discussing the fundamental concepts of VFB and studying on the methodology of implementation, we discuss how to integrate the VDMS into AUTOSAR component model without violating the AUTOSAR standard. And then we design the system architecture of the VDMS.This thesis focuses on the following aspects:(1) Investigation of automotive control systems development, and analysis of the latest AUTOSAR standard, especially the relevant parts of the AUTOSAR software-architecture and methodology.(2) Utilize the benefits of Component-Based Software Engineering, propose a hybrid VDMS model, and the software components of the VDMS can be distributed over arbitrary number of ECUs in every subsystem.(3) Detailed analyze the VDMS software-components and SW-Cs description, Investigation how to how to integrate the VDMS into AUTOSAR environment, design the system architecture of the VDMS.(4) We design a "Virtual—real" experiment environment based on AUTOSAR standard, and it is succeed on the fictitious environment, Apply the VDMS in Airbag system, Analysis the performance of the system.
