AUTOSAR 기반 BSW 모듈 확장을 위한 BSW 스케쥴러와 인터럽트 핸들러 분석 및 적용 방법

Abstract

Recently, the usage of electronic devices in the automotive industry has been increasing dramatically. In order to control these devices effectively, AUTOSAR(AUTomotive Open System ARchitecture), which is a standard software architecture, has been released. However, since AUTOSAR has a complicated structure and highly depends on development tools, it is difficult to use AUTOSAR effectively for the development process. In this paper, we propose a method, which makes developers directly modify AUTOSAR BSW modules without any supports of tool vendors. We describe operating behaviors of the BSW scheduler and interrupt handlers in AUTOSAR BSW layer, then we propose a method to selectively execute and control main processing functions and interrupt handlers in BSW modules.
