Ensuring functional safety by networking systems from different domains, illustrated by the example of an electromechanical brake

Abstract

The customer’s demand for novel functionalities in modern vehicles requires reconsidering the traditional architecture of vehicle electronics and the continuous further development of individual systems. Especially, driver assistance and safety systems lead to increasing functional complexity and demand powerful actuators to intervene into vehicle handling. These trends increasingly cause by-Wire systems to invade critical components as the steering or braking system. While supporting the achievement of functional goals driven by the application, these systems come along with challenges in terms of functional safety if cost objectives have to be met.
