摘要:

在高速和操纵极限下的轨迹规划是一项具有挑战性的任务。为了满足比赛场景的要求,我们提出了一个有远见的两步,多层基于图的轨迹规划器,能够运行速度高达212公里/小时。该规划器被设计为生成多个可驱动轨迹的动作集,允许相邻的行为规划器为场景中的全局状态选择最合适的动作。该方法用于诸如赛道跟踪、跟随、停止、超车以及能够在摩擦极限下操纵车辆的速度曲线的目标。因此,它提供了一个高的更新率,一个长远的规划视野和解决方案,非凸的情况。所提出的方法的能力,证明在模拟和一个真正的赛车。

英文摘要:

Trajectory planning at high velocities and at the handling limits is a challenging task. In order to cope with the requirements of a race scenario, we propose a far-sighted two step, multi-layered graph-based trajectory planner, capable to run with speeds up to 212~km/h. The planner is designed to generate an action set of multiple drivable trajectories, allowing an adjacent behavior planner to pick the most appropriate action for the global state in the scene. This method serves objectives such as race line tracking, following, stopping, overtaking and a velocity profile which enables a handling of the vehicle at the limit of friction. Thereby, it provides a high update rate, a far planning horizon and solutions to non-convex scenarios. The capabilities of the proposed method are demonstrated in simulation and on a real race vehicle.
