The project partners are striving to create new processes by which safety systems can be efficiently developed in compliance with ISO standard 26262. VeTeSS (“Verification and Testing to Support Functional Safety Standards”) is focused in particular on parts and components of subsystems that must be developed reliably in order to prevent defects in subcomponents from leading to the malfunctioning of safety-critical components. The results of VeTeSS will allow defects in the design of safety components to be corrected at an earlier stage than is possible today, further improving the quality and robustness of the electrical and electronic systems. This will also lower the risk of integrating components that do not satisfy the ISO norm into complex systems.
The increasing complexity of the safety components in vehicles produces an elevated risk of design errors in the development process. Electronic systems must therefore be continuously tested and verified during the design stage, but until now, every manufacturer has used different methods to achieve this. The ISO standard 26262 requires a uniform testing and verification method currently being developed by the VeTeSS partners. This also makes it possible to certify subcomponents individually without reference to a specific overall system so that they can subsequently be used in various systems, such as electric servo control or anti-lock brake systems. The processes can also be employed in all development phases.
Within this project, Fraunhofer IIS/EAS is developing methods and tools for rapid evaluation of a complete system consisting of intelligent sensors, an electronic control unit with a microcontroller as a central computer and the power electronics.
VeTeSS is being supported by the Federal Ministry for Education and Research (BMBF) and the European Union within the ARTEMIS Joint Undertaking.
