What is Fatigue Driving Alert?
2 Answers
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.
I value this feature the most when driving long distances. When the dashboard suddenly flashes a coffee cup icon, I know it's time to take a break. Nowadays, mid-to-high-end cars are mostly equipped with millimeter-wave radar + cameras, which can monitor steering wheel movements and lane deviations. My friend's Volvo is even more amazing—the system will directly tighten the seatbelt and blow cold air from the AC onto your face when it detects anomalies. I recommend buying a car with fatigue monitoring, as dozing off for just two seconds on the highway means driving blind for dozens of meters. Recently, I found that after driving for three hours straight, the seat vibration reminder is more effective than beeping sounds, as it doesn't startle you and cause shaky hands.
