摘要:

由于目前自动驾驶和车辆主动安全的发展,越来越需要能够实时执行复杂关键性预测的算法。能够处理多对象交通场景有助于实现各种汽车应用,例如用于碰撞预防和缓解的驾驶员辅助系统以及自动驾驶汽车的后备系统。我们提出了一个完全基于模型的算法与并行架构。该算法可以通过模拟数百万个轨迹组合和检测物体之间的碰撞来评估复杂的多模式(车辆和行人)交通场景的危险性。该算法能够在非常早期的阶段估计即将到来的临界状态,展示了其在车辆安全系统和自动驾驶应用中的潜力。在测试车辆中的嵌入式系统上的实现以原型的方式证明了该算法与现代汽车的硬件可能性的兼容性。对于包含11个动态对象的复杂交通场景,在Drive PX~2的GPU上,在21 ms内评估了超过8600万个姿势组合。

英文摘要:

Due to the current developments towards autonomous driving and vehicle active safety, there is an increasing necessity for algorithms that are able to perform complex criticality predictions in real-time. Being able to process multi-object traffic scenarios aids the implementation of a variety of automotive applications such as driver assistance systems for collision prevention and mitigation as well as fall-back systems for autonomous vehicles. We present a fully model-based algorithm with a parallelizable architecture. The proposed algorithm can evaluate the criticality of complex, multi-modal (vehicles and pedestrians) traffic scenarios by simulating millions of trajectory combinations and detecting collisions between objects. The algorithm is able to estimate upcoming criticality at very early stages, demonstrating its potential for vehicle safety-systems and autonomous driving applications. An implementation on an embedded system in a test vehicle proves in a prototypical manner the compatibility of the algorithm with the hardware possibilities of modern cars. For a complex traffic scenario with 11 dynamic objects, more than 86 million pose combinations are evaluated in 21 ms on the GPU of a Drive PX~2.
