A large developer of automotive systems from abroad developed an electronic steering system which was to be verified and validated for the sake of getting official licence for the use in Europe. The electronic system consists of sensors adjusted to a conventional steering wheel which transfer the angle information to a microprocessor based control system. This system itself is - via a process interface - connected to a series of final elements (valves) that manage the steering process. With the IEC 61508 /IEC 61508/ there is an international standard available that provides profound guidelines for the development and use high quality embedded systems. On a first glance it looks as though the standard might be fit for practical application. However, going into very detail of the standard and dealing with the requirements demanded there leads to severe problems which are based mainly on the size of the standard and the even high number of requirements. In addition a majority of requirements is 'hidden' somewhere in the text and not to be identified obviously. To solve this problem it is recommended to use support tools. In the following presentation it will be demonstrated how IEC 61508 is being applied in a concrete project and which procedures have been developed to make work efficient and to meet customer's time and cost requirements.
