广州车展首日，雷军没有出现在小米汽车的发布会上。 作者 | 周智宇 编辑 | 张晓玲 站在台前的，是小米汽车副总裁李肖爽。除了技术迭新，李肖爽演讲的核心只有一个：安全。屏幕上， 是不加小字注释的三行大字——安全是前提，安全是基础，安全是一切。 营销味突然淡去，将安全牌打上牌桌。今年深陷舆论漩涡的小米，正在发生一些微妙的变化。 广州车展上，李肖爽没有谈论那些锦上添花的功能，重点展示的Xiaomi HAD增强版以及安全辅助功 能。 在智能驾驶的上半场，行业普遍采用"规则驱动"或基础的"数据驱动"。这就像是让司机死记硬背交规， 或者通过模仿记忆来开车。但这种模式很快遇到了天花板：面对极端稀缺的场景，由于缺少训练样本， 模型无法有效学习。 小米此次打出的"世界模型"，本质上是构建了一个高保真的虚拟仿真引擎。在这个虚拟世界里，系统不 再依赖现实中必须发生的事故来学习，而是可以通过"日夜兼程"的模拟演练，在海量生成的场景中试错 ——"走对了加分、走错了扣分"。 这种从"模仿"到"认知"的范式转移，目的是试图通过算法的泛化能力，去覆盖那些长尾的风险场景，从 而降低系统性的行车风险。 此次小米HAD增强版AEB也全面升级，A ...
