A CASE STUDY ON MIGRATING TOWARDS FUNCTIONALLY SAFE ZONAL ARCHITECTURE USING MBSE

Abstract The increasing market demands in recent times are driving complexity in machines and their control architectures. To satisfy these demands, their architecture needs frequent updates and upgrades which in turn require significant efforts from architects. This paper presents a case study on architecture migration in automotive industry using Model Based System Engineering (MBSE) which will lend a helping hand in successfully rearchitecting any complex system. The Automotive industry is currently undergoing a massive transformation towards software defined vehicles driven by Connected, Autonomous, Shared and Electrification (C.A.S.E). This is possible only with the support of a robust and flexible vehicle Electrical and Electronics (EE) architecture. Taking the C.A.S.E driven transformation into consideration, the present domain control architecture is migrating towards zonal architecture. This paper presents RAZA (Rearchitecting Approach for Zonal Architecture) which is based on the INCOSE defined technical process and ISO/IEC/IEEE 15288:2015 Systems and software engineering — System life cycle processes.
