本发明公开了一种疲劳驾驶监测系统及安装该系统的方向盘,属于驾驶辅助技术领域,具体包括:数据获取模块,用于通过方向盘中的传感器采集驾驶员身体指标,所述身体指标包括汗液盐分浓度、心率和握力;数据处理模块,用于根据所述身体指标生成正向化矩阵,将所述正向化矩阵归一化生成标准化矩阵,利用欧氏距离计算驾驶员的身体指标评分;疲劳判断模块,用于绘制身体指标评分随时间变化曲线,当所述变化曲线当前坐标的切线斜率持续大于预设阈值超过预设时长,则发出轻度预警,当所述身体指标评分大于预设阈值时,发出重度预警,并对驾驶员进行物理刺激;本发明实现对了驾驶员疲劳驾驶的稳定监测。

    The invention discloses a fatigue driving monitoring system and a steering wheel provided with the system, and belongs to the technical field of driving assistance, and the system specifically comprises a data acquisition module which is used for collecting body indexes of a driver through a sensor in the steering wheel, and the body indexes comprise sweat salt concentration, heart rate and grip strength; the data processing module is used for generating a forward matrix according to the body indexes, normalizing the forward matrix to generate a standardized matrix, and calculating the body index score of the driver by using the Euclidean distance; the fatigue judgment module is used for drawing a change curve of a body index score along with time, sending out a mild early warning when the tangent slope of the current coordinate of the change curve is continuously greater than a preset threshold for a preset duration, and sending out a severe early warning and carrying out physical stimulation on a driver when the body index score is greater than the preset threshold; according to the invention, the fatigue driving of the driver is stably monitored.
