The invention discloses a T-shaped intersection way-giving control method in an automatic driving environment. The method comprises the following steps: establishing a determination area and a control area by taking an intersection as a center; acquiring vehicle position information and vehicle running state information entering the system in real time; finding out all conflicting vehicles, and respectively judging conflicting scenes and conflicting situations to which the vehicles belong; and determining a first group of vehicles generating conflicts and respectively calculating delay time of alternative schemes corresponding to the three conflict situations under the conflict situations to which the vehicles belong. According to the invention, automatic driving is taken as a technical background, T-shaped intersection way-giving control is taken as a research object, delay time of vehicles in the system is considered, and a T-shaped intersection way-giving control strategy considering system requirements and system advantages is provided.

    本发明公开了一种自动驾驶环境下T型交叉口让行控制方法,包括:以交叉口为中心建立一个确定区和控制区;实时获取进入系统的车辆位置信息及车辆运行状态信息;找出所有冲突车辆,并分别判断其所属的冲突情景与冲突情形;确定第一组产生冲突的车辆并分别计算其所属冲突情景下的三种冲突情形对应的备选方案的延误时间。本发明以自动驾驶为技术背景,以T型交叉口让行控制作为研究对象,考虑系统内车辆的延误时间,提出了一种兼顾系统需求和系统优势的T型交叉口让行控制策略。
