Analysis of Zonal and Distributed Based Architecture with MBSE Approach through Duration Simulation

Present study aims to analyze different E/E architectures trending in automotive industry currently. This study shows the comparison analysis done between zonal architecture and distributed architecture. Comparison methodology includes duration simulation performed for a vehicle feature on both architectures. Present study has adopted MBSE approach for the analysis. Study includes analysis done for distance control, airbag activation and rear park assist features developed on zonal and domain architecture. Duration simulation is also performed on same feature on both architectures. While performing duration simulation of all above features on both zonal and distributed architecture time constraints where assumed based on run time machine performance. Results shows that when only feature must be executed distributed architecture is more feasible. However, when feature has been made more updatable, upgradable and scalable Zonal architecture has been more feasible. To summarize study shows that a hybrid E/E architecture will be best feasible for new coming connected, and software defined Vehicles.
