This dissertation addresses methods for the performance evaluation of in-vehicle communication for future safety systems. Based on real measurement data, transmission effects and key system parameters are identified, which serve as input for a UML-based simulation model. In the simulation, the functionality and timing behaviour of relevant components are reproduced and meaningful performance metrics are determined. To investigate the worst-case communication behaviour of time- and safety-critical applications, the analytical method of Network Calculus was extended and applied. The results represent guaranteed upper bounds for transmission latencies and, together with measurements and simulations, allow a comprehensive performance evaluation of the networked safety system at an early design stage as well as a significant increase in efficiency.
