The invention belongs to the technical field of traffic control, and discloses a secondary road vehicle speed guiding method for a primary road priority control intersection in an automatic driving environment, which comprises the following steps of: selecting an urban road primary road priority control intersection, taking a vehicle driving into a starting point of a secondary road speed guiding area as a target vehicle, and performing speed guiding; establishing a speed guiding model of the secondary road target vehicle; acquiring traffic information of the main road priority control intersection, and transmitting the traffic information to an automatic driving auxiliary system of the target vehicle; the automatic driving assistance system of the target vehicle predicts whether a traversal gap exists in the conflict area or not, and if yes, an acceleration speed guiding strategy is implemented on the target vehicle and the target vehicle travels the conflict area; and if not, the automatic driving assistance system of the target vehicle continues to find the next traversal gap, and a speed guidance strategy of performing driving guidance in a speed guidance area or stopping and waiting in front of a stop line of the intersection is implemented on the target vehicle.
本发明属于交通控制技术领域,公开了一种自动驾驶环境下主路优先控制交叉口的次路车辆速度引导方法,包括以下步骤:选取城市道路主路优先控制交叉口,以驶入次路速度引导区域起点的车辆为目标车辆并实行速度引导;建立次路目标车辆的速度引导模型;获取主路优先控制交叉口的交通信息,并传递给目标车辆的自动驾驶辅助系统;目标车辆的自动驾驶辅助系统预测冲突区是否存在可穿越间隙,若存在,则对目标车辆实施加速的速度引导策略并穿越冲突区;若不存在,则目标车辆的自动驾驶辅助系统继续寻找下一个可穿越间隙,并对目标车辆实施在速度引导区域进行行驶引导或者在交叉口停车线前停车等待的速度引导策略。
