AUTOMOTIVE SAFETY INTEGRITY LEVEL
A development methodology for safety-critical systems
Project leader: Bert Dexters
In 1771, brake failure on a steam-driven vehicle caused an accident. Ever since, the safety aspects of vehicles have become increasingly important. This project follows this development. It aims to minimise the risks of an accident due to faulty development or external failures. Today, these risks are relatively high due to the integration of electro-mechanical and software components which have greatly increased vehicles' complexity. This complexity can lead to faults or failures which, in turn, can cause dangerous situations. So a methodology was developed for this project for a more systematic approach to systems development and the management of projects, with the intention of better managing complexity and minimising the risk of errors. Despite the fact that an ever-increasing number of safety systems are fitted to vehicles, acquiring knowledge in this domain is very relevant, not only for safety reasons but also for economic reasons.

Goals
- Improve know-how and competencies to ensure a functional approach to safety
-
To make systems development more predictable, which will also have a positive impact on productivity and costs
Methodology
All relevant functional safety standards were studied. The project then examined the methods which are applied to systems development today. The results were stored in a database. Based on this, a generic development method for processes, system architecture and technologies will be drawn up. The methodology will be refined further on the basis of two industrial user applications.
Phases
- Studying the different functional safety standards
- Making the inventory of the current processes and safety architectures
- Definition of a generic development methodology for the development of safety-critical systems
- Validation and refinement of this development methodology in two industrial applications
