+## 导出 CAN 报文 PDF
+
+PDF 与 `docs/AMI_CAN_DBC说明.md` 使用同一份内容，按 A4 横向排版并嵌入中文字体。在仓库根目录运行：
+
+```powershell
+python -m pip install -r scripts/requirements-pdf.txt
+python scripts/export_dbc_docs.py
+python scripts/export_can_pdf.py
+```
+
+默认使用 Windows 黑体 `C:/Windows/Fonts/simhei.ttf`；其他环境可通过 `--font` 指定支持中文的 TrueType 字体。输出为 `output/pdf/AMI_CAN报文说明.pdf`。修改 DBC 后，需重新导出 Markdown 和 PDF。
