The embodiment of the invention provides a cooperative intersection method for multi-mode driving vehicles in an expressway confluence area under a mixed driving condition, and belongs to the technical field of intelligent vehicle-road cooperation, and the method comprises the steps: obtaining the vehicle information of a lane outside a main road and the vehicle information of a ramp within the range of a vehicle-road information detection system; according to the main road outer side lane vehicle information and the ramp vehicle information, the dynamic safety distance needed by the ramp vehicles to converge into the main road is calculated in real time, and the dynamic safety distance comprises the overtaking converge real-time dynamic safety distance and the deceleration converge real-time dynamic safety distance; according to the dynamic safe distance, predicting whether a ramp vehicle conflicts with a vehicle outside the main road at a certain moment when the ramp vehicle merges into the main road; and regulating and controlling the running state of the ramp vehicle according to a conflict prediction result, so as to realize safe and efficient convergence of the ramp vehicle into the main road. According to the invention, the problems of disordered vehicle confluence and low efficiency in the expressway confluence area under the condition of multi-mode driving vehicle mixed driving are effectively solved.
本发明实施例提供一种混行条件下快速路合流区多模式驾驶车辆协同交汇方法,属于智能车路协同技术领域,该方法包括获取车路信息检测系统范围内主路外侧车道车辆信息和匝道车辆信息;根据所述主路外侧车道车辆信息和匝道车辆信息,实时计算匝道车辆汇入主路所需的动态安全距离,所述动态安全距离包括超车汇入实时动态安全距离和减速汇入实时动态安全距离;根据所述动态安全距离预测匝道车辆汇入主路时是否在某一时刻与主路外侧车辆发生冲突;根据冲突预测结果进行匝道车辆运行状态的调控,来实现匝道车辆安全高效地汇入主路。本发明有效解决了快速路合流区在多模式驾驶车辆混行情况下车辆汇入杂乱无章且效率低的问题。
