The invention discloses a system and a method for early warning and controlling danger of automatic driving on-ramp and off-ramp of an expressway. The system comprises a high-speed portal frame monitoring point installed on a high-speed lane, a ramp monitoring point installed on a ramp and a vehicle-mounted automatic driving domain controller installed on a vehicle waiting for lane changing. The high-speed portal frame monitoring point is used for monitoring the motion state of a target vehicle in each high-speed lane, analyzing the collision risk of the target vehicle in each high-speed lane and a vehicle waiting for lane changing, and judging whether the vehicle waiting for lane changing can change lanes safely or not. The invention provides an expressway automatic driving on-ramp and off-ramp danger early warning control system and method, which can improve the reliability of environmental perception, monitor the traffic conditions of ramps and expressway main roads adjacent to the ramps, eliminate vehicle blind areas, judge traffic risks in advance, control vehicles to go on and off the expressway ramps, and improve the safety of the expressway automatic driving on-ramp and off-ramp danger early warning and control the expressway automatic driving on-ramp and off-ramp danger early warning. And carrying out early warning on the lane changing risk and the driving risk when the user goes on and off the ramp.

    本发明公开了一种高速公路自动驾驶上下匝道危险预警控制系统及方法,系统包括安装在高速车道上的高速龙门架监测点、安装在匝道上的匝道监测点以及安装在待变道车辆上的车载自动驾驶域控制器;所述高速龙门架监测点用于监控高速各车道内的目标车辆的运动状态,分析高速各车道内目标车辆与待变道车辆的碰撞风险,判断待变道车辆是否能够安全变道。本发明提供一种高速公路自动驾驶上下匝道危险预警控制系统及方法,提高环境感知的可靠性,同时监测匝道以及和匝道毗连的高速主干道的交通状况,消除车辆盲区,提前判断交通风险并控制车辆的上下高速匝道,对上下匝道时的变道风险和行驶风险进行预警。
