摘要:

我们设计和实验评估的混合安全的结构防撞控制器的自动驾驶汽车。该控制器将自适应控制器和离散安全控制器各自的优点结合到单个架构中。自适应控制器依赖于模型预测控制以在标称条件下实现最佳效率。安全控制器通过分别针对标称和非标称条件应用两种不同的策略来避免冲突。我们提出了自适应和安全控制器的设计原则,并展示了每个控制器如何在混合架构中做出贡献,以提高性能,道路占用率和乘客舒适度,同时保持安全性。实验结果证实了该方法的可行性和混合控制器的安全和有效的驾驶的实际意义。

英文摘要:

We design and experimentally evaluate a hybrid safe-by-construction collision avoidance controller for autonomous vehicles. The controller combines into a single architecture the respective advantages of an adaptive controller and a discrete safe controller. The adaptive controller relies on model predictive control to achieve optimal efficiency in nominal conditions. The safe controller avoids collision by applying two different policies, for nominal and out-of-nominal conditions, respectively. We present design principles for both the adaptive and the safe controller and show how each one can contribute in the hybrid architecture to improve performance, road occupancy and passenger comfort while preserving safety. The experimental results confirm the feasibility of the approach and the practical relevance of hybrid controllers for safe and efficient driving.
