摘要:

预测驾驶员意图是高级驾驶员辅助系统的一项困难而关键的任务。传统的预测置信度度量通常忽略了预测轨迹影响下游安全驾驶决策的方式。在本文中,我们提出了一种新的多任务的意图识别神经网络,预测不仅概率驾驶轨迹,但也实用统计与给定的下游任务的预测。我们建立了一个决策标准的并行自主权,考虑到驾驶员轨迹预测的作用,在实时决策推理估计的特定任务的效用统计。我们进一步提高我们的系统的鲁棒性,考虑下游规划任务,可能会导致不安全的决策的不确定性。我们在一个现实的城市驾驶数据集上测试了我们的在线系统,并证明了与基线方法相比,它在召回和脱落指标方面的优势,并证明了它在干预和警告用例中的有效性。

英文摘要:

Predicting driver intentions is a difficult and crucial task for advanced driver assistance systems. Traditional confidence measures on predictions often ignore the way predicted trajectories affect downstream decisions for safe driving. In this paper, we propose a novel multi-task intent recognition neural network that predicts not only probabilistic driver trajectories, but also utility statistics associated with the predictions for a given downstream task. We establish a decision criterion for parallel autonomy that takes into account the role of driver trajectory prediction in real-time decision making by reasoning about estimated task-specific utility statistics. We further improve the robustness of our system by considering uncertainties in downstream planning tasks that may lead to unsafe decisions. We test our online system on a realistic urban driving dataset, and demonstrate its advantage in terms of recall and fall-out metrics compared to baseline methods, and demonstrate its effectiveness in intervention and warning use cases.
