This post describes a recent automotive ECU architecture, the edge and zone architecture.
The architecture of automotive ECUs is shifting from a traditional domain architecture to an “Edge and Zone architecture” that leverages Edge and Zone computing. Re-organizing ECU functions based on an Edge and Zone architecture facilitates the realization of a software-defined vehicle (SDV) architecture.
Edge computing is used to ensure real-time performance, system coordination, and distributed processing, and ECUs are typically located near the device being controlled, such as four-wheel suspension control.
Zone computing is used to simplify vehicle wiring and integrate functions, with ECUs located in zones such as the front and rear of the vehicle, panels, left and right doors, etc.For example, integrated door control is an example.
