      <description>「NLR/NREL FASTSim（Future Automotive Systems Technology Simulator）是开源车辆功率train能耗仿真器：给一辆车 + 一条工况（UDDS/HWFET/自定义遥测），秒级算出油耗/电耗/续航。本文面向零基础，从名词表、三大对象 Vehicle/Cycle/SimDrive、到 Rust 内核逐模块拆解（道路负荷功率五项分解、向后看 Newton 速度求解、Trace Miss 四种策略、Conv/HEV/PHEV/BEV 功率train、HEV SOC 平衡迭代）、Python 绑定与车辆数据库（含比亚迪 Atto 3/Dolphin），再讲清它和 CARLA 等闭环驾驶仿真的分工，最后给出「测所有车能耗」的实操脚本与汇报口述。」</description>
