The invention discloses an intelligent network connection automobile decision-making method and system for an intersection without signal lamps, and the method comprises the following steps: 1, obtaining the road environment information of the intersection and the information of traffic participants; 2, predicting a future trajectory of the traffic participant; 3, intersection driving conflict points of the main vehicle and other traffic participants are generated based on the future trajectory, and intersection driving conflict areas are generated with the conflict points as the circle centers; calculating the distance between the conflict areas of the adjacent intersections and selecting for processing; traversing all intersection driving conflict areas to obtain intersection driving conflict areas related to the main vehicle; and 4, calculating the occupation time of the conflict area, judging whether a collision event occurs or not, and adjusting the driving speed of the controlled main vehicle. Aiming at a widely existing intersection without a signal lamp, vehicles which do not support automatic driving or are uncontrollable and traffic participants which cannot be neglected in actual driving scenes such as pedestrians, bicycles, motorcycles and the like are brought into decision management of the intersection, and the method has relatively high practicability.

    本发明公开了一种用于无信号灯路口的智能网联汽车决策方法及系统,包括以下步骤,步骤1,获取路口道路环境信息及交通参与者信息;步骤2,预测交通参与者的未来轨迹;步骤3,基于未来轨迹生成主车与其他交通参与者的路口行驶冲突点,以该冲突点为圆心生成路口行驶冲突区域;计算相邻路口的冲突区域的距离并选择进行处理;遍历所有路口行驶冲突区域,得到与主车有关的路口行驶冲突区域;步骤4,计算冲突区域的占用时间,判断碰撞事件是否发生,调节受控主车行驶速度。本发明针对广泛存在的无信号灯路口,把不支持自动驾驶或不可控的车辆,以及行人、自行车、摩托车等实际驾驶场景中不容忽视的交通参与者纳入路口的决策管理,具有较强的实用性。
