AI总结:

针对自动驾驶需可证明安全的需求,提出基于MPC的安全框架,可在满足约束下跟踪参考轨迹,经仿真和实车实验验证了其有效性与实时性。

摘要:

自动驾驶系统要在全球范围全面部署,就要求自动驾驶车辆以可证明安全的方式运行,即车辆必须能在任何可能的交通场景中避免碰撞。本文提出了一种基于模型预测控制(Model Predictive Control,MPC)的框架,为自动驾驶车辆提供必要的安全保障。具体而言,该框架始终确保约束满足,同时在障碍物允许的范围内尽可能跟踪参考轨迹,从而实现安全且舒适的驾驶行为。为讨论该框架的性能和实时能力,我们首先给出了一个说明性仿真示例,随后通过真实测试车辆的实验验证了框架的有效性。

英文摘要:

The full deployment of autonomous driving systems on a worldwide scale requires that the self-driving vehicle be operated in a provably safe manner, i.e., the vehicle must be able to avoid collisions in any possible traffic situation. In this paper, we propose a framework based on Model Predictive Control (MPC) that endows the self-driving vehicle with the necessary safety guarantees. In particular, our framework ensures constraint satisfaction at all times, while tracking the reference trajectory as close as obstacles allow, resulting in a safe and comfortable driving behavior. To discuss the performance and real-time capability of our framework, we provide first an illustrative simulation example, and then we demonstrate the effectiveness of our framework in experiments with a real test vehicle.
