According to the driver fatigue state monitoring and controlling method and system, whether a driver is in a fatigue state or not is determined by collecting facial parameters in the driving process of the driver and analyzing the blinking frequency, the blinking time, the yawning times and the yawning frequency, and when the system judges that the driver is in the fatigue state, a whole vehicle related system is actively awakened, so that the fatigue state of the driver is monitored. A driver is stimulated and the mental state of the driver is improved by changing the smell and temperature in the vehicle or starting an entertainment system in the vehicle, and after the system is started, if the system still judges that the driver is in a fatigue state within a period of time, the driver is reminded of the direction and distance of the nearest service area and suggested to have a rest in the service area; and when the driver is on fatigue driving, the system can continuously remind, so that the driving safety risk is reduced to the greatest extent, and road traffic accidents are avoided.
本发明提供一种驾驶员疲劳状态监测及控制方法及系统,通过对驾驶员行车过程面部参数采集,对眨眼频率、眨眼时间、打哈欠次数及频率的分析,确认驾驶员是否处于疲劳状态,当系统判定驾驶员处于疲劳状态时,主动唤醒整车相关系统,通过改变车内气味、温度或开启车内娱乐系统,刺激驾驶员,改善驾驶员精神状态,当该系统启动后,如果在一段时间内,系统依旧判定驾驶员处于疲劳状态,提醒驾驶员最近服务区方向及距离,建议驾驶员在服务区休息,当驾驶员执意疲劳驾驶时,系统会持续进行提醒,最大程度降低驾驶安全风险,避免道路交通事故。
