The invention provides an intersection smooth vehicle speed guiding method based on V2X, and the method comprises the steps: enabling a target vehicle carrying intelligent vehicle-mounted equipment to receive the information, such as signal timing and current phase, transmitted by an intersection signal lamp after entering a guiding interval, and employing the parameters, such as the current lamp color remaining time, the current vehicle speed, and the distance between the vehicle and a stop line, and judging whether the vehicle can stably pass through the intersection at a constant speed or at a variable vehicle speed without stopping. According to the intersection smooth vehicle speed guiding method, vehicle speed guiding is carried out on the vehicle entering the intersection guiding interval, the vehicle can pass through the intersection without stopping, waiting time is shortened, passing efficiency is improved as far as possible, and meanwhile the s-shaped acceleration and deceleration algorithm is utilized, so that a speed curve is smooth, and driving stability is improved.
本发明提供了一种基于V2X的交叉口平滑车速引导方法,搭载智能车载设备的目标车辆进入引导区间后,能够接收到路口信号灯传递的的信号配时和当前相位等信息,并利用当前灯色剩余时间、当前车速、车辆距停止线距离等参数,判断车辆能否匀速或通过变化车速,平稳且不停车通过交叉口。本发明所述的交叉口平滑车速引导方法,通过对进入交叉口引导区间的车辆进行车速引导,尽可能做到不停车通过交叉口,减少等待时间,提高通行效率,同时利用s形加减速算法,使得速度曲线平滑,提高驾驶平稳性。
