Abstract:
The automotive industry is increasingly focusing on connected vehicles that have the opportunity to connect to external platforms, such as the cloud or edge. In this context, the electric/electronic (E/E) architecture is evolving from a signal-oriented to a service-oriented architecture where loosely coupled services, representing functions or the software components (SWCs) they are composed of, can be dynamically connected. At the same time, realization by means of independent services enables the execution both in the vehicle and in the communication network, like the cloud. The costs involved in developing, operating, and maintaining vehicle SWCs have a significant impact on whether it makes sense to execute them in the cloud. In this paper, the authors propose an approach to calculate the total cost of ownership (TCO) with Capital Expenditures (CapEx) and Operating Expenses (OpEx) of SWCs for the two different execution platforms, vehicle and cloud. The TCO model includes the lifecycle of the function from development to usage and maintenance. In a case study with a machine learning SWC for the heating, ventilation and air conditioning (HVAC) function, the model is investigated and break-even periods for the two platforms are calculated.
