The invention discloses a method and device for determining a forced lane changing afflux point of an intelligent vehicle. The method comprises the steps of obtaining the lane changing microscopic information of a target vehicle, and the lane changing microscopic information comprising the speed and position data of the target vehicle, a leading vehicle in a target lane and a following vehicle; calculating a critical safety gap between the target vehicle and the following vehicle in the target lane; according to the free lane change type and the forced lane change type, calculating a polite factor mean value of the effective lane change number; determining a weight coefficient representing a driving characteristic, and calculating a polite factor of forced lane changing of the current intelligent vehicle; and according to the position relationship between the target vehicle and the leading vehicle in the target lane, calculating and determining the afflux point of forced lane changingof the current intelligent vehicle. According to the method provided by the invention, the interaction between the lane changing vehicle and the front and rear vehicles in the target lane is comprehensively considered, the lane changing afflux point selection is more accurate, a scientific and reasonable judgment and decision basis is provided for a driver or the intelligent vehicle, and a guarantee is provided for road traffic safety and driving efficiency.

    本发明公开了一种智能车强制换道汇入点确定方法及装置,方法包括:获取目标车辆换道微观信息,包括目标车辆、目标车道内前导车辆和跟随车辆的速度、位置数据;计算目标车辆和目标车道内跟随车辆的临界安全间隙;根据自由换道和强制换道类型,计算有效换道数量的礼貌因子均值;确定代表驾驶特性的权重系数,计算当前智能车强制换道的礼貌因子;根据目标车辆和目标车道内前导车辆的位置关系,计算确定当前智能车强制换道的汇入点。本发明提供的方法综合考虑换道车辆与目标车道内前后车的相互作用,换道汇入点选择更加精确,进而为驾驶员或智能车提供科学合理的判断和决策依据,为道路交通安全和行驶效率提供保障。
