The invention relates to the technical field of automatic driving, and provides a longitudinal decision-making system and a longitudinal decision-making determination method for an automatic driving vehicle. The longitudinal decision-making system comprises a distance calculation unit used for calculating distance parameters, including one or more of an action distance, an AEB distance, an expected vehicle following distance and a maximum vehicle speed limit distance, of a vehicle relative to a front vehicle on the same lane, a state switching unit for switching the longitudinal driving stateaccording to the distance parameters and environmental information of the vehicle, and a state determining unit for determining and outputting the current longitudinal driving state of the vehicle according to the switching result of the state switching unit. With the distance parameters, especially the action distance, the road passing rate can be effectively improved on the premise that safety is guaranteed; the system is suitable for full-speed road conditions; and since the distance parameters are adjustable, the system is suitable for drivers of different driving styles.
本发明涉及自动驾驶技术领域,提供一种自动驾驶车辆的纵向决策系统及纵向决策确定方法。本发明所述的纵向决策系统包括:距离计算单元,用于计算本车相对于同一车道的前车的距离参数,其中所述距离参数包括动作距离、AEB距离、期望跟车距离和最高车速极限距离中的一者或多者;状态切换单元,用于根据所述距离参数和所述本车的环境信息进行纵向行驶状态的切换;以及状态确定单元,用于根据所述状态切换单元的切换结果,确定并输出所述本车的当前所处的纵向行驶状态。本发明利用距离参数,特别是动作距离,可以在保证安全的前提下,有效地提高道路通行率,适用于全速路况,同时距离参数可调,适用于不同驾驶风格的驾驶员。
