Implementation of AUTOSAR I/O driver modules for a SSPS system

The AUTOSAR Basic Software is composed of Service Layer, ECU Abstraction Layer (EAL), Microcontroller Abstraction Layer (MCAL) and Complex Driver. In these components, an IO Driver Module including I/O Hardware Abstraction (IoHwAb) is one of the most important components in a development of ECU-target applications. However, it is difficult to integrate and emulate it to ECU-targets in coincidence with the AUTOSAR MCAL/EAL architecture. In this paper, we present a simple implementation process of an AUTOSAR IO Driver module and system integration method. In addition, we apply this development process to the Speed Sensitive Power Steering (SSPS) system and evaluate its performance as a result of applied tests.
