The invention discloses an intelligent automobile automatic driving method which comprises the steps of selecting a target automobile based on a traffic intersection where a main automobile is located, judging whether collision occurs according to whether space-time overlapping exists or not, if so, judging whether only speed control can be carried out without changing a path to avoid potential collision or not, and if not, carrying out speed control. And if not, path planning and speed planning are carried out again. Potential collision at the intersection can be avoided, the safety of the intelligent automobile passing through the intersection is improved, and meanwhile certain passing efficiency and riding comfort are guaranteed.
本发明公开了一种智能汽车自动行驶方法,包括:基于主车所在交通路口,选取目标车辆,以是否存在时空重叠来判定是否发生碰撞,若判定会发生碰撞,则再判断能否不改变路径仅进行速度控制避免潜在碰撞,不可行则重新进行路径规划和速度规划。本发明能够避免路口潜在的碰撞,提高智能汽车通过路口的安全性,同时保证一定的通行效率和乘坐舒适性。
