Early ECUs only managed basic engine functions. Modern ECUs have evolved into domain controllers and central computing platforms that integrate power, chassis, body, and cockpit systems. Supported by high-performance MCUs and SoCs, next‑generation ECUs support AI computing, over‑the‑air (OTA) updates, and functional safety up to ASIL‑D. This trend greatly simplifies wiring, reduces failure risks, and prepares vehicles for software‑defined mobility and autonomous driving.
