E/E Architecture: enabling software-defined cars
The migration to more centralized architectures has started and will accelerate from 2025. While the industry generally agrees on the need to evolve from distributed to centralized architectures to support Software Defined Cars and new business models such as paid updates and OTA, this migration is complex and disruptive. The pace of adoption will differ based on the portfolio of OEMs, ranging from baby steps to giant implementation strides. The E/E Architecture revolution is also disrupting the supply chain. Whilst new components and specifications emerge, some components will become obsolete and some standardized. In this presentation, S&P Mobility describes - with a number of real examples - how the industry will transition from distributed to fully centralized architectures.
The shift toward more centralized architectures has initiated and is poised to gain momentum starting in 2025. While there is a general consensus within the industry regarding the necessity to transition from distributed to centralized architectures to facilitate Software Defined Cars and innovative business models like paid updates and Over-the-Air (OTA) capabilities, this migration is intricate and transformative. The speed of adoption will vary, contingent on the OEMs' portfolios, ranging from cautious initial steps to substantial implementation leaps. Simultaneously, the revolution in Electrical/Electronic (E/E) Architecture is causing disruptions in the supply chain. As novel components and specifications emerge, certain components will become obsolete, and standardization will play a role. In this presentation, S&P Mobility elucidates, using real examples, the industry's journey from distributed to fully centralized architectures.
