Driven by the megatrend of aerial vehicles, there is an enormous increase in Unmanned Aerial Vehicles (UAVs) that opens up a new field of possibilities, applications, and services to the industry and public. The technological advancements along with the use of electronic control units in UAVs increases complexity. It requires high computing power, power management, and robust electrical and electronic architecture than they are currently used. There is no existing E/E architecture standard for UAVs. In this paper, we design a novel E/E architecture for UAVs. The new E/E architecture for UAVs allows for the integration of more complicated and sophisticated functionalities inboard UAVs, including low battery consumption management, efficient navigation, high-performance, chassis, stability control, etc. We also presented future UAV E/E architecture based on zones for safe operations.
