This paper presents an application software design and a simulation environment implementation, based on AUTOSAR software platform, for electric power steering (EPS) system. A software architecture with applicable control logics is proposed in conformity with AUTOSAR standard document. In addition, a design of tasks and runnables along with the architecture are developed, which consist of application software, in this paper. Furthermore, a software in the loop(SIL) simulation test bed, using Matlab and CANoe tools, is implemented to validate the proposed EPS development processes.
