SAE automation level

SAE 自动驾驶等级，由 SAE International 在 J3016 标准中定义，从 L0（无自动化）到 L5（完全自动驾驶），是自动驾驶研究、法规与媒体报道中最通用的分级框架。

English Definition

"A taxonomy from SAE International standard J3016 that classifies driving automation from Level 0 (no automation) to Level 5 (full automation), the most widely used framework in automotive HCI and policy."

用法说明 · 针对中文母语者

常见缩写成 L0–L5。L3 = 有条件自动驾驶，系统主导，必要时请求人类接管；L4 = 高度自动驾驶，在限定的 ODD（运行设计域）内无需人类接管；L5 = 完全自动驾驶。注意区分 SAE 与中国 GB/T 自动驾驶分级。

常见错误

·中文里常译为'级别'或'层级'，英文应统一用 level；不要把 SAE J3016 与 NHTSA 早期五级版本混用，两者边界划分略有差异。
