智能汽车通过配备车载环境感知系统和信息终端实现车内外交互，从而具备了智能环境感知能力，能够自动分析行驶过程中的安全与危险状态，规划路径并控制车辆按规划路径行驶，但内外连接增多使其面临复杂网络安全威胁。因此，本文将探讨智能汽车信息系统所面临风险的特性，以期为保障智能汽车的安全可靠运行提供参考。

Intelligent vehicles, equipped with on-board environmental perception systems and information terminals, have achieved information exchange with the external environment (such as people, vehicles, and roads), thereby possessing intelligent environmental perception capabilities. They can automatically analyze safety and dangerous states during driving, plan routes, and control the vehicle to travel along the planned path. However, the increase in internal and external connections exposes them to complex network security threats. Therefore, this article will explore the characteristics of the risks faced by intelligent vehicle information systems, with the aim of providing references for ensuring the safe and reliable operation of intelligent vehicles.
