Steer-by-wire systems come with a number of benefits compared to conventional steering systems in terms of functionality, package and weight. However these systems were never introduced in the market in a large scale. As one of the reasons, costs for the necessary safety measures can be identified. In order to increase the economical attractiveness of such systems it is possible to increase the efficiency of safety concepts without reduction of their effectiveness. The measures described above show how the efficiency of safety concepts can be increased based on the experience of the SpeedE project. Main idea is to keep the solution space as wide as possible, not to miss efficient measures by a too limited focus in the early concept phase. Supported by a consistent data management and verification, efficient safety concepts can be derived. Applied to the example of SpeedE steer-by-wire these measures lead to a functional safety concept with an increased efficiency compared to concepts which work mainly on component redundancy. By making use of other existing components and systems with the potential to influence the yaw-moment of the vehicle, the number of redundancies can be limited and the appropriate demands in terms of costs, installation space, and weight are reduced.
