核心要求

Euro NCAP 2026 首次奖励无响应驾驶员检测与干预系统:

“Technologies that can detect a medical emergency or extreme intoxication and safely bring the vehicle to a controlled halt.”


干预等级

等级 触发条件 系统动作
Level 1 轻度异常 声音警告
Level 2 中度异常 声音 + 视觉 + 震动警告
Level 3 重度异常 警告 + ADAS 敏感度提升
Level 4 无响应 ESF 紧急停车

2. ADAS 集成要点

要点 建议
延迟要求 < 100ms 从检测到警告
冗余设计 多传感器交叉验证
安全等级 ISO 26262 ASIL-B
HMI 设计 清晰的警告层级

总结

Euro NCAP 2026 ESF 要求标志着 DMS 从被动监测升级为主动安全干预。关键点:

  1. 分级警告:渐进式警告机制
  2. 自动干预:无响应时自动停车
  3. DMS-ADAS 协同:驾驶员状态驱动车辆行为
  4. 安全停车:解锁车门 + 呼叫救援
