The invention discloses an automatic driving takeover risk assessment and man-machine friendly early warning method and an early warning system. The early warning method comprises the steps: firstly calculating a takeover risk value during takeover of automatic driving; and then transmitting a corresponding mode of takeover early warning to a driver according to a man-machine friendly takeover early warning algorithm so as to remind the driver to carry out takeover operation. The early warning system is based on the early warning method and comprises an automatic driving judgment module, a takeover demand module, a vehicle takeover risk value assessment module and an alarm module. An automobile is integrated with the early warning system. In the invention, multiple risk sources are comprehensively considered, a risk of taking over the vehicle caused by multiple physical objects in the traffic is analyzed, the risk of a takeover moment is evaluated in combination with takeover reactioncharacteristics of the driver of the vehicle, meanwhile, a comfort degree of the driver is considered, the man-machine friendly early warning method is established, takeover safety of automatic driving can be guaranteed, and a user experience of the driver is improved. The method can further provide technical support for an intelligent driving auxiliary system.

    本发明公开了自动驾驶接管风险评估和人机友好预警方法及预警系统,预警方法在于首先计算自动驾驶接管时的接管风险值,然后根据人机友好接管预警算法向驾驶人发出相应方式的接管预警,以提醒驾驶人进行接管操作;预警系统基于预警方法,包括自动驾驶判断模块、接管需求模块、本车接管风险值评估模块和报警模块;汽车集成有预警系统。本发明在综合考虑多风险源的情况下,分析交通中的多物理对象对本车接管造成的风险,结合本车驾驶人的接管反应特性,对接管时刻的风险进行评估,同时考虑驾驶人的舒适度,建立了人机友好预警方法,可以保障自动驾驶接管安全性,同时提高驾驶人的用户体验,该方法还能为智能驾驶辅助系统提供技术支持。
