近日，小米汽车公布了一项关于疲劳驾驶干预的专利，引发广泛关注。该专利旨在通过多模态传感器融合技术，实时监测驾驶员的生理状态和行为特征，如眼睑闭合频率、头部姿态、方向盘操作习惯等，以判断其是否处于疲劳或注意力分散状态。一旦系统识别出潜在风险，将通过声音提醒、座椅震动、空调调节甚至自动减速等方式进行分级干预，从而有效预防交通事故的发生。与传统仅依赖摄像头的方案不同，小米的这项专利整合了车内多个传感器数据，包括红外摄像头、毫米波雷达、方向盘扭矩传感器以及生物信号检测模块，提升了识别准确率和环境适应性。尤其在夜间、强光或佩戴墨镜等复杂场景下，系统仍能稳定运行。此外，该技术还支持与智能座舱系统联动，例如自动播放提神音乐或建议就近停车休息。作为小米进军智能电动汽车领域的重要布局之一，这项专利不仅体现了其在人机交互与主动安全技术上的创新能力，也彰显了小米打造‘人车家全生态’战略的决心。未来，该技术有望率先搭载于小米SU7系列车型，为用户提供更安全、更智能的出行体验。
Recently, Xiaomi Auto unveiled a patent for a fatigue-driving intervention system, drawing widespread attention. The patent leverages multi-modal sensor fusion technology to monitor drivers’ physiological states and behavioral patterns in real time—such as eye blink frequency, head posture, and steering wheel handling habits—to assess signs of drowsiness or distraction. Upon detecting potential risks, the system initiates tiered interventions, including audible alerts, seat vibrations, climate control adjustments, or even automatic speed reduction, to help prevent accidents.Unlike conventional approaches that rely solely on cameras, Xiaomi’s solution integrates data from multiple in-cabin sensors, including infrared cameras, millimeter-wave radar, steering torque sensors, and biometric monitoring modules. This significantly enhances detection accuracy and robustness across challenging conditions like nighttime driving, bright sunlight, or when drivers wear sunglasses. Moreover, the system can interact with the vehicle’s intelligent cockpit—for instance, by playing alertness-enhancing music or suggesting nearby rest stops.As a key part of Xiaomi’s strategic entry into the smart electric vehicle market, this patent highlights the company’s innovation in human-machine interaction and active safety technologies, reinforcing its vision of an integrated ‘Human-Vehicle-Home’ ecosystem. The technology is expected to debut on Xiaomi’s SU7 series, offering users a safer and smarter driving experience.
