The invention discloses a vehicle automatic driving method for a congested road condition and an automatic driving vehicle. The method comprises the steps that whether a vehicle is currently in the congested road condition or not is judged according to an average vehicle speed and a braking frequency; if yes, whether a guiding vehicle exists in a lane where the vehicle is located currently or notis judged; if the guide vehicle exists in front of the driver, a driver is prompted to be in the congestion road condition at present and is about to enter an automatic driving mode in a congestion state; if the driver does not actively refuse to enter the automatic driving mode, a vehicle control system enters the automatic driving mode in the congestion state; and in the automatic driving mode,a power system is controlled according to the relative distance, the relative speed and the relative acceleration, and the relative distance between the vehicle and the guiding vehicle is controlled within a certain safe distance range. According to the invention, the vehicle can be controlled to automatically drive along with a front vehicle under the congestion road condition, the burden of thedriver is reduced, and the safety of automatic driving of the vehicle is improved.

    本发明公开了一种针对拥堵路况的车辆自动驾驶方法及自动驾驶车辆,该方法包括以下步骤:根据均车速、制动频率判断当前是否处于拥堵路况;若当前处于拥堵路况,则辨别当前所在车道内是否存在引导车辆;若前方存在引导车辆,则提示驾驶员当前处于拥堵路况,且即将进入拥堵状态下的自动驾驶模式;如驾驶员不主动拒绝进入自动驾驶模式,车辆控制系统将进入拥堵状态下的自动驾驶模式;自动驾驶模式下,根据相对距离、相对速度、相对加速度控制动力系统,将本车辆与引导车辆之间的相对距离控制在一定安全距离范围之内。本发明可以控制车辆在拥堵路况下跟随前车进行自动驾驶,减轻了驾驶员的负担,提高了车辆自动驾驶的安全性。
