The invention provides a vehicle self-adaptive cruise speed control method. The method comprises the steps that the current cruise speed of a vehicle and driving information of other vehicles in a left lane and a right lane of the vehicle are obtained; determining a first safe driving speed range and a second safe driving speed range of the vehicle in the current lane according to the driving information of other vehicles on the left side and the right side of the vehicle; judging whether the current cruise speed belongs to the intersection of the first safe driving speed range and the second safe driving speed range or not; when it is determined that the current cruise vehicle speed belongs to the intersection, the vehicle continues to run according to the current cruise vehicle speed; and when it is determined that the current cruise speed does not belong to the intersection, the limit value close to the current cruise speed in the intersection is taken as the target cruise speed, and the vehicle runs according to the target cruise speed. According to the invention, the driving of the vehicle is associated with the related other vehicles in the surrounding traffic flow, and the influence of the other vehicles is concerned at any time, so that the vehicle can fuse the driving environment around the vehicle and cruise according to the decided speed.

    本发明提供了一种车辆自适应巡航车速控制方法,获取自车的当前巡航车速、自车的左侧车道和右侧车道内的他车驾驶信息;根据自车左右两侧的他车驾驶信息确定自车在当前车道内的第一安全驾驶车速范围和第二安全驾驶车速范围;判断当前巡航车速是否属于第一安全驾驶车速范围和第二安全驾驶车速范围的交集内;在确定当前巡航车速属于交集内时,使自车按照当前巡航车速继续行驶;在确定当前巡航车速不属于交集内时,取交集中靠近当前巡航车速的极限值作为目标巡航车速,并使自车按照目标巡航车速行驶。本发明使得自车的行驶与周围交通流中相关他车关联,时刻关注他车的影响,进而使得车辆能够融合自车周围的驾驶环境,按决策的速度进行巡航。
