L2级自动驾驶的意思是部分自动驾驶，在SAE中的定义是“车辆对方向盘和加速中的多项操作供给驾驶，而驾驶员负责其余的驾驶动作”。简单来说，L2级自动驾驶就是在行驶过程中能够同时自动实行加减速和转向的操作。不过，在整个行驶过程中，驾驶员必须维持注意力集中，实时监控周围驾驶环境以及随时预备接管车辆。

L2级自动驾驶有哪些功能

像自适应巡航系统、AEB主动制动系统和车道维持铺助这些都是L2级自动驾驶的“一般”功能，除此之外还有适用于于不相同场景的一系列驾驶铺助功能。

</P><P>AEB主动制动系统</P><P>在特定的情形下，系统会主动帮助驾驶员实行制动动作，进而防止或降低事故的发生，这也同样是自动驾驶铺助中不可或缺的功能之一，常出现于当驾驶员分心而来不及制动时供给的制动铺助。</P><P><a href="zb_users/upload/tu/10301610432.jpg" data-fancybox="images" /><img
