The invention is suitable for the technical field of auxiliary driving, and particularly relates to a vehicle following distance adjusting method and system in the vehicle automatic lane changing process, a sensing fusion module is used for collecting vehicle motion information, a motion parameter obtaining module is used for obtaining current vehicle motion parameter information, and a system triggering module is used for receiving a lane changing instruction. The safety distance judgment module is used for judging whether lane changing control is carried out or not, the safety distance judgment module is used for dynamically optimizing the safety distance based on driving habits of a driver, the control calculation module is used for calculating longitudinal control parameters and transverse control parameters needed for controlling lane changing of the vehicle, and the control execution module is used for controlling the vehicle to change the lane. Relevant parameters of lane changing path planning are dynamically adjusted according to the position relation and the speed relation between the vehicle and the target vehicle, so that relevant transverse and longitudinal control of the vehicle is controlled, and the automatic lane changing process is completed. From the perspective of a driver, the method is closer to the lane changing process of a real driving vehicle of the driver, and the comfort and safety of function use are improved.

    本发明适用于辅助驾驶技术领域,尤其涉及一种车辆自动变道过程中跟车距离调整方法及系统,感知融合模块用于采集车辆运动信息,运动参数获取模块用于获取当前车辆的运动参数信息,系统触发模块用于接收变道指令,判断是否进行变道控制,安全距离判断模块用于基于驾驶员的驾驶习惯对安全距离进行动态优化,控制计算模块用于计算控制车辆变道所需的纵向控制参数和横向控制参数,控制执行模块用于控制车辆进行变道。本发明根据自车和目标车辆的位置关系、速度关系动态调整变道路径规划的相关参数,从而控制自车的相关横纵向控制,完成自动变道过程。从驾驶员角度出发,更贴近驾驶员真实驾驶车辆的变道过程,提升功能使用的舒适性和安全性。
