论文摘要
本文提供了一种估计从事合作感知的自动化地面车辆碰撞风险的技术。该技术允许量化(i)由于合作而降低的风险,以及(ii)由于合作而提高的风险评估准确性。如果两者都重要,则可以将合作视为满足日益自动化车辆的严格风险预算的理想做法;如果不是这样,那么不必追求合作 - 及其各种弊端。根据动态概率占用图和将相关状态信息映射到成本度量的损失功能,对自我车辆的轨迹进行了碰撞风险。风险评估框架是使用从穿越城市十字路口的两辆合作的车辆捕获的实际数据来证明的。
This paper offers a technique for estimating collision risk for automated ground vehicles engaged in cooperative sensing. The technique allows quantification of (i) risk reduced due to cooperation, and (ii) the increased accuracy of risk assessment due to cooperation. If either is significant, cooperation can be viewed as a desirable practice for meeting the stringent risk budget of increasingly automated vehicles; if not, then cooperation - with its various drawbacks - need not be pursued. Collision risk is evaluated over an ego vehicle's trajectory based on a dynamic probabilistic occupancy map and a loss function that maps collision-relevant state information to a cost metric. The risk evaluation framework is demonstrated using real data captured from two cooperating vehicles traversing an urban intersection.
