The invention discloses a steering wheel information early warning method and system during automatic driving quitting, and the method comprises the steps: judging whether a driver actively takes over a vehicle or not when detecting that the vehicle quits automatic driving, if yes, determining that the quitting mode of the vehicle quitting the automatic driving is an active take-over mode, and if not, determining that the vehicle quits the automatic driving is an active take-over mode; if yes, determining that the exit mode of the vehicle exiting the automatic driving is an abnormal takeover mode; acquiring a steering angle of a steering wheel when the vehicle exits automatic driving; if the steering angle is not zero, according to the exit mode, warning signals are generated based on the steering angle to conduct early warning, and the warning signals in different exit modes are different in early warning level. The problem that when an original vehicle exits from an automatic driving mode, safe driving of the vehicle is affected by factors such as non-alignment of a steering wheel is solved.
本申请公开了一种退出自动驾驶时的方向盘信息预警方法及系统,该方法包括:检测到车辆退出自动驾驶时,判断是否为驾驶员主动接管车辆,其中,若是,则确定车辆退出自动驾驶的退出方式为主动接管模式,若否,则确定车辆退出自动驾驶的退出方式为异常接管模式;获取车辆退出自动驾驶时方向盘的转向角度;若所述转向角度不为零,则根据所述退出方式,基于所述转向角度生成警示信号进行预警,其中,不同退出方式下的警示信号的预警等级不同。本申请解决了原有的车辆在退出自动驾驶模式时,因方向盘未回正等因素影响车辆安全行驶的问题。
