This paper discusses a new approach to materialize for automotive embedded software and validation method. Automotive systems have tended to be equipped with many electronic systems in order to satisfy with driver’s needs and the Road Traffic Act of each country. This means that automotive systems have to be controlled by embedded software simultaneously, so that the embedded software should be complicated and vehicle should be equipped with many embedded software. The embedded software is developed dependently on hardware. The embedded software is changing whenever the hardware specification is changing. And software test is only being performed with hardware without testifying software itself. That is inefficient way in the view of time and cost. To resolve these problems, AUTOSAR which consists of the standardized interfaces and structures, was introduced. The AUTOSAR proposes software architecture to improve embedded software independently on hardware. This paper suggests an automotive safety system based on AUTOSAR to testify the propriety as a standard architecture, and proposes testing method and technique to validate software itself without adopting it to hardware. Finally, AUTOSAR is demonstrated as standardized software architecture, and suggests testing technique to enhance the accuracy and reduce the time to testify for automotive embedded software.
