Connectivity and systems integration together with weight and production cost reduction are among the main objectives of the automotive industry in electric vehicles development in particular, when concerns with smart grids integration and interoperability increases. At the same time vehicle systems reliability plays an important role as a decisive factor for market acceptance. Conventional automotive electrical systems comprehend a central ECU, with radial wiring harness architecture with power and signal cables. A different architecture is proposed with the aim of vehicle cable mass and cost reduction, simplification and increased reliability of the whole electrical control system. With this architecture there's also the aim to provide computing and communications capability to each electric component in a distributed way, in order to enable its integration with external systems like smart phones, networking services and smart grids.
