摘要:

在本文中,提出了一种自主开发的控制器算法的目标是处理一个基本的停车操作。自动驾驶汽车控制的最大挑战之一是正确的校准和为给定条件找到正确的车辆模型。由于许多其它研究,模型预测控制(MPC)结构已经开始成为最有前途的控制技术。在我们的工作中,我们从白皮书中实现了MPC功能。考虑到低速条件下的停车机动,我们使用的运动学自行车模型作为控制器的基础。该算法有两个主要输入:规划轨迹和车辆状态反馈信号。该控制器被实现为Simulink模型,并使用ROS框架集成到一个完整的自主控制系统。通过多个步骤验证结果:仅使用Simulink与纯运动自行车工厂模型;使用包含真实车辆模型和整个软件链的LGSVL仿真框架;控制器为真实车辆测试做好准备。

英文摘要:

In this paper a self-developed controller algorithm is presented with the goal of handling a basic parking maneuver. One of the biggest challenges of autonomous vehicle control is the right calibration and finding the right vehicle models for the given conditions. As a result of many other research, model predictive control (MPC) structures have started to become the most promising control technique. During our work we implemented an MPC function from white paper. Considering the low-speed conditions of a parking maneuver we use a kinematic bicycle model as the basis of the controller. The algorithm has two main inputs: a planned trajectory and the vehicle state feedback signals. The controller is realized as a Simulink model, and it is integrated into a complete autonomous control system using ROS framework. The results are validated through multiple steps: using Simulink only with a pure kinematic bicycle plant model; using LGSVL simulation framework containing a real vehicle model and the entire software chain; the controller is prepared for real vehicle tests.
