The invention relates to a safety processing method for an automatic driving collision risk. The method comprises the steps that P1, a vehicle independently receives sensing, positioning and map information; p2, on the basis of the information, a perception module of the vehicle perceives the targets to carry out dangerous target screening so as to obtain potential dangerous targets; p3, performing threat judgment on the potential dangerous target, and outputting a decision result corresponding to an emergency situation based on a decision algorithm, a delay control algorithm, an adjustment decision threshold and an emergency braking algorithm; and P4, outputting a decision result corresponding to the emergency situation to a control module of the vehicle. According to the method, a safety processing mechanism when the sensing information is abnormal and the decision algorithm fails is analyzed, and the driving safety is ensured to the greatest extent.
本发明涉及一种自动驾驶碰撞风险的安全处理方法。该方法包括:P1:车辆独立接收感知、定位、地图信息;P2:基于上述信息,所述车辆的感知模块感知目标进行危险目标筛选,以得到潜在危险目标;P3:针对所述潜在危险目标进行威胁判断,基于决策算法、延迟控制算法、调整决策阀值和紧急制动算法,输出紧急情况对应决策结果;P4:将所述紧急情况对应决策结果输出给所述车辆的控制模块。本发明分析了感知信息异常及决策算法失效时的安全处理机制,最大程度保证了行车安全。
