Purpose and goal

The electrical system of a vehicle is becoming more and more complex with an increasing number of nodes and complex sensors, e.g., cameras and radars. There is a need to ensure that testing effort scales well under these conditions. The purpose of SAGA is to contribute with knowledge and tools to achieve more adequate scenario based integration testing of automotive systems, while maintaining or improving test resource utilization efficiency.

Expected results and effects

By lifting the abstraction level of tests and test sequences, and automating their construction, the test effort in MIL, SIL and HIL environments will be able to scale with higher complexity and new sensors. SAGA will stimulate increased research activities as it connects to an internationally strong distributed Swedish research environment. The main SAGA result will be a toolchain and accompanying adoption guidelines for automated generation and analysis of tests of such systems

Planned approach and implementation

Saga will explore how ´Guarded Assertions´ and the generation of test sequences can contribute to achieving more adequate scenario based integration testing of automotive systems, while maintaining or improving test resource utilization efficiency. This will be done through the development of methods for (1) generating test sequences guided by situational testing and maximum varying test cases, and (2) Guarded Assertions. Work will be performed iteratively at Scania and SICS and continuously evaluated throughout the project.
