摘要:

遵循模块化方法的传统自动驾驶汽车管道过去在学术界和工业界都非常成功,这导致了道路上的自动驾驶。虽然这种方法提供了方便的解释,其推广到看不见的环境是有限的,需要手工设计的许多参数,特别是在预测和规划系统。最近,深度强化学习已被证明可以学习复杂的战略游戏并执行具有挑战性的机器人任务,这为学习驾驶提供了一个有吸引力的框架。在这项工作中,我们提出了一个深度强化学习框架,使用航点和低维视觉表示(也称为启示)来学习最优控制策略。我们证明,我们的代理从零开始训练时学习的任务车道跟踪,驾驶周围的交叉路口,以及停止在前面的其他演员或交通灯,即使在密集的交通设置。我们注意到,我们的方法在CARLA模拟器上实现了与原始基准方法和NoCrash基准方法相当或更好的性能。

英文摘要:

Traditional autonomous vehicle pipelines that follow a modular approach have been very successful in the past both in academia and industry, which has led to autonomy deployed on road. Though this approach provides ease of interpretation, its generalizability to unseen environments is limited and hand-engineering of numerous parameters is required, especially in the prediction and planning systems. Recently, deep reinforcement learning has been shown to learn complex strategic games and perform challenging robotic tasks, which provides an appealing framework for learning to drive. In this work, we propose a deep reinforcement learning framework to learn optimal control policy using waypoints and low-dimensional visual representations, also known as affordances. We demonstrate that our agents when trained from scratch learn the tasks of lane-following, driving around inter-sections as well as stopping in front of other actors or traffic lights even in the dense traffic setting. We note that our method achieves comparable or better performance than the baseline methods on the original and NoCrash benchmarks on the CARLA simulator.
