A driving assistance system and method for a motorcade are disclosed herein; the motorcade includes a head vehicle and at least one following vehicle located behind the head vehicle. The driving assistance system includes: an obstacle information acquisition unit configured to acquire position information of an obstacle in front of the head vehicle having a risk of collision with the motorcade; a lateral environment information acquisition unit which is configured to be used for acquiring lateral environment information of the head vehicle and the following vehicle of the motorcade so as to judge whether an object influencing lane changing of the vehicle exists on one side or two sides of the head vehicle and/or the following vehicle or not; a processor which is configured to be used for calculating the total number of the head vehicles needing to change lanes to avoid and the following vehicles sequentially adjacent to the head vehicles in the motorcade according to the position information of the obstacles, the lateral environment information, the driving speed of the motorcade and the preset vehicle deceleration, and sending corresponding lane changing commands to vehicles needing to change lanes to avoid in the motorcade, and sending corresponding braking commands to other remaining following vehicles.
一种用于车队的驾驶辅助系统和方法,车队包括头车和位于头车后面的至少一个跟随车辆,其中,驾驶辅助系统包括:障碍物信息获取单元,被配置用于获取头车前方的与车队存在碰撞风险的障碍物的位置信息;侧向环境信息获取单元,被配置用于获取车队的头车以及跟随车辆的侧向环境信息,以判断在头车和/或跟随车辆的一侧或两侧是否存在影响车辆变道的物体;处理器,被配置用于根据障碍物的位置信息、侧向环境信息、车队的行驶速度和预设的车辆减速度计算车队中需要采取变换车道进行躲避的头车及其依次相邻的跟随车辆的合计数目,以及发送相应的变道命令给车队中需要采取变换车道进行躲避的车辆,以及发送相应的刹车命令给剩余的其他跟随车辆。
