The invention discloses a complex traffic road condition vehicle lane changing overtaking anti-collision method and system based on vehicle and road cloud integration, and the method comprises the steps: enabling a target vehicle to generate a target lane changing overtaking intention when the target vehicle cannot reach an expected speed; when the target lane is the same-direction driving left-side lane, the distance between the target vehicle and the front vehicle is larger than a first safety distance threshold value, and the distance between the target vehicle and the rear vehicle of the same-direction driving left-side lane is larger than a second safety distance threshold value, the target vehicle is controlled to change the lane to the same-direction driving left-side lane; when the target lane is the opposite driving lane, the distance between the target vehicle and the front vehicle is larger than a first safety distance threshold value, and the distance between the target vehicle and the opposite driving vehicle is larger than a third safety distance threshold value, the target vehicle is controlled to borrow the opposite driving lane to exceed the front vehicle. According to the method provided by the invention, the problem of collision caused by uncertain behaviors of other vehicles in a complex road environment in the lane-changing overtaking process of the vehicle can be solved.

    本发明公开了一种基于车路云一体化复杂交通路况车辆变道超车防碰撞方法及系统,该方法包括:在目标车辆达不到期望速度时,目标车辆产生通过目标车道变道超车意图;当目标车道为同向行驶左侧车道时,目标车辆与前车的距离大于第一安全距离阈值且目标车辆与同向行驶左侧车道后方车辆的距离大于第二安全距离阈值时,控制目标车辆变道到同向行驶左侧车道;当目标车道为对向行驶车道时,目标车辆与前车的距离大于第一安全距离阈值且目标车辆与对向行驶车辆的距离大于第三安全距离阈值时,控制目标车辆借用对向行驶车道超越前车。本发明提供的方法能够解决车辆在变道超车过程中,由复杂的道路环境、其他车辆的不确定行为导致的碰撞问题。
