The invention discloses an automatic lane changing method for a vehicle. The method specifically comprises the following steps that current surrounding environment information of a target vehicle and vehicle information of the target vehicle are obtained; judging whether the target vehicle generates a lane changing intention or not; if yes, judging whether the target vehicle meets a lane changing condition or not; when the target vehicle meets the lane changing condition, automatic lane changing is carried out; judging whether a lane changing interruption condition is triggered in the lane changing process of the target vehicle; if yes, controlling the target vehicle to return to the own vehicle lane; and if not, controlling the target vehicle to drive into the target lane. According to the method, deceleration lane changing, constant-speed lane changing and acceleration lane changing are flexibly selected on the basis of different lane changing scenes in the lane changing process, so that the vehicle adopts different lane changing strategies on the basis of the different lane changing scenes in the lane changing process, potential safety hazards in the lane changing process of the vehicle are reduced, and the lane changing efficiency in the lane changing process of the vehicle is improved.

    本发明公开了一种车辆自动换道方法,方法具体包括以下步骤:获取目标车辆的当前周围环境信息和目标车辆的车辆信息;判断目标车辆是否产生换道意图;若是,判断目标车辆是否满足换道条件;当目标车辆满足换道条件时,则进行自动换道;判断目标车辆换道过程中是否触发中断换道条件;若是,则控制目标车辆返回自车车道;若否,则控制目标车辆驶入目标车道。本发明通过在变道过程中基于不同的变道场景灵活选择减速变道、匀速变道和加速变道,使得车辆在变道过程中,基于不同变道场景而采用不同的变道策略,既减小了车辆变道过程中的安全隐患,又提高了车辆变道过程中的变道效率。
