The invention provides a vehicle track planning method and system, and relates to the field of vehicle automatic driving. A slave controller receives the motion information of the target obstacle from the master controller in real time, and judges whether the target obstacle exists on the running track of the vehicle or not according to the latest received motion information of the target obstacle when detecting that the master controller fails and the electronic braking system of the vehicle is in a normal state. When it is judged that the target obstacle exists on the driving track, the parking track of the vehicle is planned according to the latest received motion information of the target obstacle. The information acquisition and processing are executed by the master controller, wherein the slave controller plans the parking track based on the information acquired by the master controller under the condition that the master controller fails, so that the tedious information processing process of the slave controller is avoided, and the automatic driving function can be completely realized.

    本发明提供了一种车辆轨迹的规划方法及规划系统,涉及车辆自动驾驶领域。本发明中的从控制器实时接收来自主控制器的目标障碍物的运动信息,并在检测到主控制器失效且车辆的电子制动系统处于正常状态时,根据最新接收到的目标障碍物的运动信息判断车辆的行驶轨迹上是否存在目标障碍物;当判定行驶轨迹上存在目标障碍物时,根据最新接收到的目标障碍物的运动信息规划车辆的停车轨迹。本发明中信息获取和处理均由主控制器执行,从控制器在主控制器失效的情况下,依托于主控制器获取到的信息规划停车轨迹,避免了从控制器繁琐的信息处理过程,且能够完全实现自动驾驶功能。
