An overview is given about the processes and methods which have been defined and implemented for the development of Audi dynamic steering in order to achieve functional safety for the system. It turned out that with pragmatic, sometimes simple methods a lot of the process requirements of (IEC 61508, 1998) can be achieved, e.g., requirements management (with req. keys) leads to the mandatory traceability; release management leads to planning reliability and commitment; safety management guarantees the coordination of all safety activities at Audi and the suppliers. Especially release management lead to accelerated implementation of all support and development processes because every release step reveals shortcomings of product or process transparently. First successes of the structured development process can be acclaimed: the safety concept of the stabilisation subsystem had to be redesigned due to safety integrity requirements; two product release steps have been accomplished successfully; the system and subsystems safety concepts have been assessed through external assessor and proved their feasibility and potential to meet all functional safety requirements. It could be shown that the requirements for achieving functional safety are not a burden but are very helpful and lead to more efficient development and to higher product quality and safety.
