Modern driver assistance systems are often using a wide range of equipped sensors as primary data source. The reliability of each sensor is specified by the manufacturer and influences the system reliability distinctly. To prevent potential fatal system failures, diverse failure prevention mechanisms are included. Nevertheless, a certain level of reliability of the system has to be guaranteed to meet...
We consider regression testing of safety-critical systems consisting of black-box components. This scenario is common for automotive electronic systems where testing time is expensive and should be reduced without uncontrolled reduction of reliability. This requires a methodology to select test cases from a larger test suite for which a defined quality level of the resulting regression test cycle...
Decentralized and self-organizing mechanisms present promising approaches to deal with the massive amount of data generated by different components in the smart grid. In this work we present a self-organized approach that is able to take decisions locally and in a distributed way. Our approach distinguishes between an infrastructure level and a decision level. The middleware processes running on the...
Embedded systems become increasingly complex and distributed. Although there is necessity for thourough testing, exhaustive validiation and verification is hardly possible in industry due to time and resource restrictions. In the past the reason for this has often been that it was to time-consuming to specify, to execute, and to evaluate test cases for the first design models and the integrated embedded...
Extended Automation Method 2.0 (EXAM) is employed at AUDI AG to perform the testing of automotive systems. The main drawback of EXAM is, that each test case must be devised and created individually. This procedure is apparently awkward and error-prone. Moreover, the development of increasingly complex functionality poses new challenges to the testing routine in industry. We employed Timed Usage Models...
