  • Publication number: 20200125858
    Abstract: A power and data center (PDC) can serve as a combined data concentrator and power distributor that delivers scalable and affordable network/power redundancy into an automotive electrical/electronic architecture (E/EA) that supports partially or fully autonomous vehicles. In some embodiments, a vehicle that includes the smart E/EA is divided into zones, where each zone includes one or more PDCs and one or more sensors, actuators, controllers, loudspeakers or other devices that are coupled to and powered by their zone PDC(s). Each PDC collects and processes (or passes through) raw or pre-processed sensor data from the one or more sensors in its zone. The sensors provide their data to the PDC by way of cost efficient, short-range data links. In some embodiments, one or more actuators in each zone are coupled to their respective zone PDC, and receive their control data from the PDC over a high-speed data bus or data link.
