【Abstract】As the level of automotive intellgence continues to rise，Electronic Control Units （ECUs）are playing an increasinglycriticalroleinAdvanced DriverAssistance Systems （ADAS）.However，the traditionaldistributedECU architecturerevealssignificantbotlenecksintermsofontrolcoupling，ommunicationlatencyandfunctionaledundancy. Based on typical application scenarios of intelligent driving assistance，this study constructs comparative modelsof distributed and centralized ECU systems，and conducts simulation tests to quantitatively evaluate key performance indicatorssuch as system response latency，communication eficiency，fault tolerance，andresource utilization.The results show that a centralized domain controllr architecture can reduce control response latency by approximately 65% ，improve fault detection and recovery efficiency by more than 60% ，and significantly enhance system stability and resource utilization.The studyvalidates the technical feasibilityand performance advantages of ECU centralizationand optimization，providing theoretical support and engineering reference forthe designofelectronic architectures in future high-level autonomous driving systems.
