The invention discloses an automatic driving longitudinal planning method and system for creating a lane changing condition and a vehicle. Whether certain motion mode exists in three modes of uniform speed, uniform acceleration and uniform deceleration is predicted based on the fact that the vehicle moves according to the three modes, if the vehicle moves according to the motion mode, the condition that the lane changing condition is changed from the initial non-satisfaction condition to the satisfaction condition within the specific time can be met, and if the motion mode exists, the vehicle moves in the mode till the lane changing condition is met. According to the automatic driving longitudinal planning method for creating the lane changing condition, under the condition that many vehicles run on a target lane, the situation that a traditional lane changing condition is not met all the time and consequently lane changing fails is avoided, automatic driving lane changing is more intelligent, and safety is guaranteed.

    本发明公开一种用于创造换道条件的自动驾驶纵向规划方法、系统及车辆,基于自车按照匀速、匀加速,和匀减速三种方式进行运动,预测这三种方式中,是否存在某一种运动方式,如果自车按照这样的运动方式运动,就能够满足在特定的时间之内,换道条件由最初的不满足变成满足,如果过存在这样一种运动方式,就让自车按照这样的方式运动直至满足换道条件。本发明的用于创造换道条件的自动驾驶纵向规划方法能够在目标车道车辆较多的情况下,避免因为传统的换道条件一直不满足导致换道失败,使得自动驾驶换道更加智能,保证了安全性。
