The invention discloses a control method and system for automatic driving intervention during fatigue driving of a driver, wherein the method comprises the following steps that: during vehicle driving, the state of the driver is detected, the fatigue state information of the driver is obtained, and the vehicle automatically enters an automatic driving mode when the fatigue state information of the driver meets one of extreme fatigue conditions; the fatigue state information of the driver at least comprises the single eye closing duration of the driver in a period of time, the duration of head lowering in a period of time and the duration of yawning of the driver in a period of time; the extreme fatigue condition at least comprises that the single eye closing duration of the driver exceeds a first threshold value in a period of time; the duration of head lowering in a period of time exceeds a second threshold value; and the duration of yawning of the driver in a period of time exceeds a third threshold value. According to the invention, when the driver is in extreme fatigue and the conventional reminding mode is invalid, the driving safety can be ensured through an automatic driving intervention mode.

    本发明公开了一种驾驶员疲劳驾车时自动驾驶介入的控制方法与系统,包括以下步骤:在车辆行驶中,检测驾驶员状态,获取驾驶员疲劳状态信息,当驾驶员疲劳状态信息符合极度疲劳条件其中一项条件时,车辆自动进入自动驾驶模式;驾驶员疲劳状态信息至少包括一段时间内驾驶员单次的闭眼时长、一段时间内低头的持续时间和一段时间内驾驶员打哈欠的持续时间;极度疲劳条件至少包括一段时间内驾驶员单次的闭眼时长超过第一阈值;一段时间内低头的持续时间超过第二阈值;一段时间内驾驶员打哈欠的持续时间超过第三阈值。本发明能在驾驶员处于极度疲劳时,常规提醒方式无效时,通过自动驾驶介入的方式,确保驾乘的安全。
