摘要: 通过建立车辆二自由度单轨模型,考虑到车辆横向控制时的非线性以及随机外界干扰,基于实际交通场景中的驾驶员实际经验,并结合模糊控制理论,设计了车辆横向模糊控制器。根据横向误差和横摆角偏差推理出合适的前轮转角并输出;通过Carsim和Simulink进行联合仿真。仿真结果表明:设计的横向控制器能够使车辆平稳准确的跟踪道路中心线,实现自主沿期望轨迹行驶的目的。

Abstract: A vehicle lateral fuzzy controller was designed. First of all, a two-degree-of-freedom monorail model was established. Then, considering the nonlinearity and random external disturbance of vehicle lateral control, a vehicle lateral controller was designed, based on the drivers practical experience in actual traffic scene and combined with the theory of fuzzy control. According to the lateral error and yaw angle deviation, the appropriate front wheel rotation angle was deduced and output. Finally, the combined simulation was carried out by Carsim and Simulink. The research shows that the designed lateral fuzzy controller can make the vehicle track the center line of the road smoothly and accurately, and achieves the goal of autonomous driving along the desired trajectory.

Key words: traffic and transportation engineering, autopilot, fuzzy control, simulation verification
