The invention discloses an L2-level automatic driving vehicle takeover alarm method. The method comprises the steps of detecting a driver state, calculating a driver state takeover alarm revision coefficient KDSts, detecting an environmental condition, calculating an environmental condition takeover alarm revision coefficient KESts, and calculating a total takeover alarm revision coefficient K = KDSts * KESts; and obtaining a revised takeover alarm condition by utilizing the total takeover alarm revision coefficient K, judging whether to send out a takeover alarm request or not according to the revised takeover alarm condition, and triggering the highest-level takeover alarm if the takeover alarm request needs to be sent out. The invention further discloses an L2-level automatic driving vehicle takeover alarm system, and when the L2-level automatic driving system is used, takeover alarm with the reasonable warning degree can be sent out in time.

    本发明公开一种L2级自动驾驶车辆接管报警方法,检测驾驶员状态并计算驾驶员状态接管报警修订系数KDSts,检测环境条件,计算环境条件接管报警修订系数KESts,计算总接管报警修订系数K=KDSts×KESts;利用总接管报警修订系数K修订得到修订后接管报警条件,通过修订后接管报警条件判断是否发出接管报警请求,如需要发出接管报警请求,触发其中最高级接管报警。本发明还公开一种L2级自动驾驶车辆接管报警系统,在使用L2级自动驾驶系统时,能够及时发出合理警示程度的接管报警。
