The invention discloses a ramp convergence longitudinal control method and device fusing a virtual queue and a lane changing rule. The intelligent network connection vehicle in the ramp convergence area obtains position and speed information; projecting the position of a ramp vehicle to a main road to form a virtual queue; determining a lane changing rule, determining a control model through the lane changing rule, and finally determining the longitudinal acceleration of the vehicle. A ramp convergence process is converted into a special car following process, so that the convergence process is smoother; and a control model based on a lane changing rule is established, so that after the vehicle speed and the position are adjusted, the vehicle can be smoothly converged after reaching the convertible area.
本发明公开了一种融合虚拟队列与换道规则的匝道汇入纵向控制方法及装置。匝道汇入区域内的智能网联车辆获取位置和速度信息;将匝道车辆位置投影到主路,形成虚拟队列;确定换道规则,通过换道规则确定控制模型,最终确定车辆纵向加速度。将匝道汇入过程转化为特殊的跟驰过程,使汇入过程更加顺畅;建立基于换道规则的控制模型,使车辆速度和位置经过调整后,在到达可汇入区域后能够顺利汇入。
