The invention provides an intelligent automobile track planning method based on an indication identifier, which comprises a path planning process and a speed planning process: the path planning process comprises the following steps of: establishing an assumed pile winding point coordinate according to pile point basic data information containing pile point position information and pile point safety distance information, and forming an assumed path according to the assumed pile winding point coordinate, carrying out collision optimization on the assumed path to obtain a preferable pile winding point and planning a target path passing through the preferable pile winding point; the speed planning comprises the steps of calculating preview point coordinates metered by reference preview time by taking the path planning and the vehicle running information as references, and correcting the vehicle running speed according to the preview point coordinates. According to the planning method, the planning problem of the intelligent driving automobile in the environment where the indication mark for guiding the automobile to run is placed can be solved, and the application scene of the intelligent driving automobile is widened.

    本发明提供一种基于指示标识的智能汽车轨迹规划方法,其包括路径规划和速度规划过程:路径规划‑包括根据含有桩点位置信息和桩点安全距离信息的桩点基础数据信息建立假定绕桩点坐标,并根据假定绕桩点坐标形成假定路径,并对假定路径进行碰撞优化获得优选绕桩点并规划经过优选绕桩点的目标路径的步骤;速度规划‑包括以路径规划和车辆运行信息为参照计算以基准预瞄时间计量的预瞄点坐标并根据预瞄点坐标修正车辆运行速度的步骤。本发明的规划方法能够解决在摆放有引导车辆行驶的指示标识的环境下,智能驾驶汽车的规划问题,拓宽的智能驾驶汽车的应用场景。
