非平面车辆导航模型与预测控制

Models and Predictive Control for Nonplanar Vehicle Navigation

Thomas Fork, H. Eric Tseng, Francesco Borrelli

摘要:

我们提出了一个简化的模型,车辆行驶在非平面道路上。采用参数曲面来描述非平面道路,该曲面可以描述曲率、坡度和坡度的任意组合。我们表明,所提出的建模方法概括了平面车辆模型,参考中心线,如Frenet模型。我们使用所提出的方法,车辆路径规划和以下使用模型预测控制。我们还对车辆与路面的接触进行建模和控制。我们表明,所提出的控制器提高了速度和车道以下的复杂道路上的平面车辆控制器相比,并减轻了复杂的路面上,包括偏离弯道的控制损失。

英文摘要:

We present a simplified model of a vehicle driving on a nonplanar road. A parametric surface is used to describe the nonplanar road which can describe any combination of curvature, bank and slope. We show that the proposed modeling approach generalizes planar vehicle models that reference a centerline, such as the Frenet model. We use the proposed approach for vehicle path planning and following using model predictive control. We also model and control vehicle contact with the road surface. We demonstrate that the proposed controller improves speed and lane following on complex roads compared to planar vehicle controllers, and mitigates loss of control on complex road surfaces including off-camber turns.
