Fatigue Driving Alert is a driver fatigue monitoring and warning product based on the physiological response characteristics of drivers. Vehicle series from brands such as Mercedes-Benz, Audi, BMW, Volkswagen, and Honda are equipped with the Fatigue Driving Alert system. The commonly equipped fatigue monitoring system is called the “Fatigue Driving Alert System”. It is based on the driver's physiological image response and consists of two major modules: ECU and camera. The system infers the driver's fatigue state by analyzing facial features, eye signals, head movements, etc., then issues alerts and takes corresponding measures. It provides active and intelligent safety protection for drivers and passengers. Main causes of driving fatigue: Sleep quality: Going to bed too late, insufficient sleep time; poor sleep quality; noisy sleeping environment that affects rest. In-car environment: Poor air quality, inadequate ventilation; excessively high or low temperature; severe noise and vibration; improperly adjusted seats; tense relationships with fellow passengers. External environment: Driving during afternoon, evening, early morning, or late-night hours; poor road conditions; monotonous road conditions; driving in sandstorms, rain, fog, or snow; poor traffic environment or congested traffic conditions. Operating conditions: Long-duration and long-distance driving; driving too fast or too slow; overly restrictive arrival deadlines. Physical condition: Poor stamina and endurance; declining vision and hearing; physical weakness or chronic illness; taking medication unsuitable for driving; special physiological periods for women (menstruation, pregnancy). Driving experience: Low skill level and unfamiliarity with operations; short driving time and lack of experience; poor safety awareness.
