The invention discloses an early warning method based on the fatigue degree of a driver, and the method comprises the steps: 1, building a personal database of the driver, and collecting the driving information of the driving driver according to a sampling period; step 2, according to the collected driving information, calculating a fatigue evaluation amount and a comprehensive fatigue evaluation amount of each piece of driving information; and step 3, according to the obtained comprehensive fatigue evaluation amount Fe, dividing fatigue grades of the driver. The personal database of the driver is established according to the acquired driving information of the driver, the fatigue state and the fatigue level of the driver are judged by calculating the personal fatigue threshold value of the driver, and a corresponding early warning mode is adopted according to the fatigue level, so that the prediction precision and the driving safety of the driver are improved.
本发明公开了一种基于驾驶员疲劳程度预警方法,包括:步骤一、建立驾驶员的个人数据库,按照采样周期,对行驶中的驾驶员的行驶信息进行采集;步骤二、根据采集到的行驶信息,计算各个行驶信息的疲劳评估量和综合疲劳评估量;步骤三、根据得到的综合疲劳评估量Fe,对驾驶员的疲劳等级进行划分。通过对采集驾驶员的行驶信息建立驾驶员的个人数据库,并通过计算驾驶员个人疲劳阈值对驾驶员的疲劳状态和疲劳等级进行判断,根据疲劳等级采取相应的预警模式,提高预测精度和驾驶员行驶的安全性。
