Abstract
The aspects safety and reliability in the application of x-by-wire-systems are a subject of intense discussions already for years. As these systems offer the possibility to improve the realization of driver-assistance-functions, the interest in this discussion is rising. In the EU-Project SPARC (Secure Propelled Vehicle With Advanced Redundant Control) [1] a new system architecture that enables an effective application of driver-assistance-systems in an X-by-wire-power train, is developed. A major challenge in the conception of such a system is the development of a reliable electrical energy supply. Because this task is highly relevant and at the same time highly complex the development should be started at an early state within the scope of the development of the entire vehicle. Designing a redundant and fault-tolerant powernet-architecture represents one of the most important working points. Components with a central meaning as e.g. the battery are dimensioned using a powernet-simulation. An energy management is implemented to detect power shortages and to initiate appropriate counter measures. This ensures the availability of electrical energy in the vehicle.
