Quality of an automobile heavily depends on reliability of the automotive system software which enables most of controllers in a vehicle to work and communicate each other. In the development of an automotive embedded system, it is important to determine if the software system meets its stated requirement, specification, and if its behavior is correct. Therefore, thorough validation of the software system is one of key factors to improve automobile quality. This paper is to address an effective automotive system software validation process not only to improve automobile quality but also to avoid high warranty cost. From the development phase to the production phase of a vehicle development, required activities from each validation phase is also discussed in detail. The automotive system software validation largely is executed in two major testing environments, system and subsystem level. Content and purpose of each testing environment is included in this paper. The software validation, however, requires experienced software test engineers and timely completion of required or planned testing. Therefore, the testing automation is a way to reduce required number of experienced test engineer and to meet a validation timing target. Two ideas of the testing automation are introduced in this paper. The first idea is to develop a modeling with MATLAB or Simulink to automatically perform testing on a system test bench or subsystem test bench. The second idea is to develop an automated testing tool within AUTOSAR (AUTomotive Open System ARchitecture) to verify automotive system software in the early phase of vehicle development life cycle.
