摘要:

解决自动驾驶中的边缘案例,头对头的自动驾驶赛车正受到业界和学术界的广泛关注。在这项研究中,我们提出了一个博弈论的模型预测控制(MPC)的方法,头对头自主赛车和数据驱动的模型识别方法。对于非线性模型参数的实际估计,我们采用了机器学习中用于神经模型训练的超带算法。该控制器包括三个模块:1)基于比赛的对手轨迹预测器,2)高级比赛策略规划器,3)基于MPC的低级控制器。基于游戏的预测器旨在预测竞争对手的未来轨迹。基于预测结果,高级竞赛策略规划器规划若干行为以响应各种竞赛环境。最后,基于MPC的控制器计算最优控制命令以跟随轨迹。所提出的方法在各种比赛情况下,在印地自主挑战赛的官方模拟器进行了验证。实验结果表明,该方法可以有效地超越竞争对手,同时驾驶通过赛道尽可能快,没有碰撞。

英文摘要:

Resolving edge-cases in autonomous driving, head-to-head autonomous racing is getting a lot of attention from the industry and academia. In this study, we propose a game-theoretic model predictive control (MPC) approach for head-to-head autonomous racing and data-driven model identification method. For the practical estimation of nonlinear model parameters, we adopted the hyperband algorithm, which is used for neural model training in machine learning. The proposed controller comprises three modules: 1) game-based opponents' trajectory predictor, 2) high-level race strategy planner, and 3) MPC-based low-level controller. The game-based predictor was designed to predict the future trajectories of competitors. Based on the prediction results, the high-level race strategy planner plans several behaviors to respond to various race circumstances. Finally, the MPC-based controller computes the optimal control commands to follow the trajectories. The proposed approach was validated under various racing circumstances in an official simulator of the Indy Autonomous Challenge. The experimental results show that the proposed method can effectively overtake competitors, while driving through the track as quickly as possible without collisions.
