The invention discloses a vehicle driving state monitoring method and system, and the method comprises the steps: obtaining the current road information, and determining the current driving state of avehicle; monitoring a steering included angle alpha between the vehicle head body and the advancing direction and a steering included angle beta between the vehicle body and the advancing direction,calculating a steering included angle difference between the steering included angle alpha and the steering included angle beta, and monitoring changes of the steering included angle difference; judging whether the steering included angle difference exceeds a preset first steering safety threshold value or not in combination with the current driving state, and when the steering included angle difference exceeds the first steering safety threshold value, starting early warning and/or takeover control to control the driving direction and/or the vehicle speed of the vehicle. By implementing the technical scheme disclosed by the invention, accidents can be effectively prevented, and the cost for monitoring the driving state of the vehicle is low.

    本公开披露一种车辆行驶状态监控方法及系统,该方法包括:获取当前道路信息,确定所述车辆的当前行驶状态;监测车头本体与其前进方向的转向夹角α、车身本体与其前进方向的转向夹角β,计算所述转向夹角α和所述转向夹角β的转向夹角差,并监测其变化;结合所述当前行驶状态,判断所述转向夹角差是否超出预设的第一转向安全阈值,并在所述转向夹角差超出所述第一转向安全阈值时,启动预警和/或进行接管控制,以控制所述车辆的行驶方向和/或车速。通过实施本公开披露的技术方案,不仅能够有效预防事故发生,而且监控车辆行使状态的成本低。
