为适配“软件定义汽车”趋势下的集中计算式电子电气架构,本文针对数字钥匙系统展开适应性开发与优化设计。首先梳理汽车电子电气架构从分布式、域控制到车云一体化集中式（EEA 3.0）的演进逻辑。随后分析传统数字钥匙系统在分布式架构下存在的功能独立、日志存储不足、数据协同能力弱等痛点。最后提出基于EEA 3.0架构的适配方案。

To adapt to the centralized computing electronic and electrical architecture under the trend of "software-defined vehicles", this paper conducts adaptive development and optimization design for the digital key system. First, sort out the evolution logic of automotive electronic and electrical architecture from distributed, domain control to vehicle-cloud integrated centralized (EEA 3.0); Furthermore, the pain points existing in the traditional digital key system under the distributed architecture, such as functional independence, insufficient log storage, and weak data collaboration ability, are analyzed, and an adaptation solution based on the EEA 3.0 architecture is proposed.
