The invention discloses an entrance ramp cooperative convergence control method for an intelligent network connection vehicle, and the method employs the advanced automatic driving technology and the wireless communication technology, and employs the real-time state information of the intelligent network connection vehicle to make a decision for a ramp convergence process. In the central controller, the required speed vf when the controlled vehicle passes through the confluence point, the required safe time headway when the controlled vehicle i passes through the confluence point and the controlled time step length delta t are preset, and the central controller is used for controlling the controlled vehicle i to pass through the confluence point based on the real-time information of the state information of the intelligent network connection vehicle. Optimizing the track of the controlled vehicle from the initial moment when the controlled vehicle enters the control area to the moment when the controlled vehicle passes through the confluence point, determining the state information of the controlled vehicle at the next moment, and controlling the controlled vehicle to move at the next moment by adopting the determined state information of the controlled vehicle at the next moment until the controlled vehicle passes through the confluence point at the speed vf, confluence is completed; the method has the advantages that traffic conflicts and energy consumption can be reduced, and traffic circulation efficiency is improved.
本发明公开了一种用于智能网联车辆的入口匝道协同汇流控制方法,利用先进的自动驾驶技术和无限通信技术,采用实时的智能网联车辆的状态信息对匝道汇流过程进行决策,中央控制器中预先设定受控车辆经过汇流点时所需的速度为vf、受控车辆i经过汇流点时所需的安全车头时距以及控制的时间步长为Δt,中央控制器基于智能网联车辆的状态信息的实时信息,对受控车辆从进入控制区域的初始时刻到通过汇流点的时刻过程中的轨迹进行优化,确定下一时刻受控车辆的状态信息,并控制受控车辆在下一时刻采用确定的下一时刻受控车辆的状态信息进行移动,直至受控车辆以速度vf通过汇流点,完成汇流;优点是能够减少交通冲突和能源消耗,提高交通流通行效率。
