The invention discloses a fatigue driving monitoring method based on vehicle-road cooperation. Transverse displacement of a vehicle relative to a reference line is collected based on a vehicle-road cooperation technology; the average value of the relative lateral displacement of the vehicle and the reference line is calculated through a plurality of lateral displacement sample data; the standard deviation of the relative lateral displacement of the vehicle and the reference line is calculated, then a fatigue index based on the standard deviation and the vehicle width is calculated; and the driving fatigue degree is graded according to the fatigue index. According to the invention, the influence of human factors on fatigue driving judgment is eliminated, the measurement accuracy is high, the adopted technical means is simple, and the operation of a driver is not influenced.

    本发明公开一种基于车路协同的疲劳驾驶监测方法,是基于车路协同技术采集车辆相对于基准线的横向位移,然后通过多个横向位移样本数据,计算车辆与基准线相对横向位移的均值,然后再计算车辆与基准线相对横向位移的标准差,然后再计算基于标准差和车宽的疲劳指数,最后根据疲劳指数对驾驶疲劳程度定级。本发明排除了人为因素对疲劳驾驶判定带来的影响,并且测量准确度高,采用的技术手段简单,不影响驾驶人操作。
