撰文 / 钱亚光 设计 / 师 超 3月29日的夜晚,一辆小米SU7标准版在高速公路行驶过程中遭遇严重交通事故。车辆燃烧起火,三个年轻人葬身高速公路。 这一事故暴露出智能辅助驾驶技术的不成熟,例如摄像头视觉感知的灵敏度在夜间和恶劣天气时会显著下降,用户盲目信赖智驾功能而导致的车祸也时 有发生,这都为市场敲响了安全警钟。 根据小米官方披露,事故发生前车辆检测到障碍物后发出预警并减速,但未触发AEB紧急制动系统。辅助驾驶退出,驾驶员接手仅2秒,碰撞就发生 了。 小米SU7标准版没有配备激光雷达,纯视觉模式在夜间识别效果相对欠佳,可能存在障碍物识别不够及时到位问题。而激光雷达可通过主动发射激光束 获取高精度三维环境数据,对环境感知精度高、可直接获取目标的距离、角度、反射强度、速度等信息且抗干扰能力较强。 这起夺命事故引发了市场对纯视觉智驾方案可靠性的质疑。长远来看,小米SU7事故或将成为智能驾驶技术路线的分水岭,有望将激光雷达从"成本选 项"跃升为"安全刚需"。 4月2日,激光雷达两家龙头企业暴涨,港股速腾聚创高开,一度涨超7%,隔夜美股禾赛大涨逾17%。而A股市场激光雷达概念股也集体走强,其中,美 湖股份涨超7% ...
