The invention discloses a motorcade guiding method based on head vehicle driving characteristics at a signalized intersection. The motorcade guiding method comprises the following steps: S1, dividing vehicles into different motorcades according to vehicle distances and instantaneous vehicle speeds; s2, obtaining a first vehicle fuzzy rule according to the historical driving data of the first vehicle; and S3, establishing a motorcade speed guiding model according to the head vehicle fuzzy rule to guide the motorcade to pass through the signalized intersection. On the basis, the behavior characteristics of tracking and guiding the speed of a head vehicle driver are represented based on a fuzzy rule, the tracking trajectory of the head vehicle is predicted, and the signal intersection motorcade speed guiding method is established by taking the motorcade passing through the intersection without stopping as a constraint condition and taking the minimum motorcade energy consumption as an optimization target. The method can improve the passing efficiency of the vehicles in the motorcade, the speed trajectory of the vehicles meets the characteristics of ecology, the actual tracking characteristics of the driver are considered, and the driver can observe, respond and control the vehicle tracking guide speed more easily.
本发明公开了一种信号交叉口基于头车驾驶特性的车队引导方法,步骤包括S1根据车间距和车辆瞬时速度将车辆划分为不同的车队;S2根据头车历史行驶数据得到头车模糊规则;S3根据头车模糊规则建立车队速度引导模型引导车队经过信号交叉口。在此基础上,基于模糊规则表征头车驾驶人跟踪引导速度的行为特性,预测头车跟踪轨迹,以车队均不停车通过交叉口为约束条件,车队能耗最小为优化目标,建立了信号交叉口车队速度引导方法。本发明能够提高车队中车辆的通行效率,车辆的速度轨迹满足生态性的特点,且考虑了驾驶人的实际跟踪特性,更有利于驾驶人观察反应并操纵车辆跟踪引导速度。
