Vehicle electrical architectures are going through a transformation to achieve the consumers demand for driver assistance, electrification and service functions.  To support modern software-defined vehicles and reduce the cost of the vehicle network, and the associated wiring harness, it is being transitioned to a domain and zonal architectures (or a combination of them). While this evolution helps address the software and cost challenges, it brings other challenges, such as how to partition safety critical real time control operations, like vehicle propulsion.
