Driving Environment Uncertainty-Aware Motion Planning for Autonomous Vehicles

چکیده
Abstract Autonomous vehicles require safe motion planning in uncertain environments, which are largely caused by surrounding vehicles. In this paper, a driving environment uncertainty-aware framework is proposed to lower the risk of position uncertainty with considering rollover. First, 4-degree freedom vehicle dynamics model, and rollover index introduced. Besides, vehicles' processed propagated based on Extended Kalman Filter method. Then, potential field established handle autonomous addition, model predictive controller designed as accounts for risk, vehicles, dynamic constraints Furthermore, two edge cases, cut-in scenario, merging scenario designed. Finally, safety, effectiveness, real-time performance demonstrated employing hardware-in-the-loop experiment bench.

متن کاملOn-Road Motion Planning for Autonomous Vehicles
We present a motion planner for autonomous on-road driving, especially on highways. It adapts the idea of a on-road state lattice. A focused search is performed in the previously identified region in which the optimal trajectory is most likely to exist. The main contribution of this paper is a computationally efficient planner which handles dynamic environments generically. The Dynamic Programm...
متن کاملSafe Motion Planning for Autonomous Driving
Self-driving cars have the potential to revolutionize transportation by making it cheaper, safer, and more efficient. In this thesis we describe a novel motion planning system, which translates high-level navigation goals into low-level actions for controlling a vehicle. Specifically, the motion planning system is responsible for choosing at each time step an appropriate velocity and steering a...
متن کاملDynamic motion planning of autonomous vehicles
This paper presents a method for planning the motions of autonomous vehicles moving on general terrains. The method obtains the geometric path and vehicle speeds that minimize motion time considering vehicle dynamics, terrain topography, obstacles, and surface mobility. The terrain is represented by a smooth cubic B patch, and the geometric path consists of a B spline curve mapped to the surfac...
