车辆平台电源管理

[中文适用范围]： 本SAE信息报告适用于所有类型的汽车电气/电子（E/E）系统架构。重要的是，应从集中式主电子控制单元（ECU）位置出发，建立标准化的方法，以向适用的且具备能力的ECU及器件发出可区分的车辆供电策略指令，从而实现最大的能量效率与热效率，并在生态系统内建立并维持复用性。因此，在全球范围内的采纳将有助于所有原始设备制造商（OEMs）与供应链在产品开发与验证方面提升效率，同时最大化ECU及器件（包括各自供电策略与能力）在OEM车辆系统间的复用。参见m。 [外文原描述]： This SAE Information Report is applicable to all types of automotive Electrical/Electronic (E/E) system architectures. It is important to develop a standard approach to commanding differentiable vehicle power policies from a centralized host Electronic Control Unit (ECU) location to applicable and capable ECUs and devices for maximum energy and thermal efficiency while creating and maintaining reuse across the ecosystem. Thus, adoption at a global level will enable efficiencies in product development and validation between all Original Equipment Manufacturers (OEMs) and the supply chain while maximizing reuse of ECUs and devices including respective power policies and capabilities between OEM vehicle systems.The definition of the Central System Power Manager (CSPM), VPPM Agent, Element Descriptor Tables, Element Descriptor Files, reference diagrams, and feature definitions are considered applicable and in scope for definition and standardization under SAE J3311.Software libraries and deployment, power state transition definition, vehicle network, protocol, component E/E topology/structure, electrical implementation schematics, and cybersecurity of transmission and storage of data are considered out of scope for definition and standardization under SAE J3311.
