The invention discloses a lane-level lane change guiding method and system based on vehicle-road cooperation, and a navigation terminal. The method comprises the following steps: the navigation terminal receives lane-level traffic flow information and lane-level congestion event information broadcasted by a roadside unit in real time in a lane-level path navigation process; the navigation terminal projects the lane-level traffic flow information to a high-precision map of the navigation terminal, and synchronously updates congestion prompt information on the high-precision map of the navigation terminal according to the lane-level congestion event information received in real time; when the vehicle is close to a congestion point position and congestion occurs in a passing lane of the vehicle, lane changing guidance is carried out in advance according to the lane-level traffic flow information and the lane-level congestion event information; according to the invention, the roadside sensing result is fused into the route planning for lane-level lane changing guidance, so that congestion can be timely guided in advance, and more reasonable, safer and faster guidance information is provided for travel.
本发明公开了一种基于车路协同的车道级变道引导方法、系统及导航终端,方法包括:导航终端在进行车道级路径导航过程中接收路侧单元实时广播的车道级车流信息和车道级拥堵事件信息;导航终端将所述车道级车流信息投射到自身的高精度地图上,根据实时接收的所述车道级拥堵事件信息在自身的高精度地图上同步更新拥堵提示信息;当接近拥堵堵点位置且拥堵发生在本车的途径车道时根据所述车道级车流信息以及车道级拥堵事件信息提前进行变道引导;本发明将路侧感知结果融合到路线规划中进行车道级的变道引导,可以对拥堵提前进行及时地引导,为出行提供更合理、更安全和更快捷的诱导信息。
