| 摘 要： | 首先,设计了一种切换缓冲区间阈值可调的切换逻辑。其次,设计了一种对车速变化具有自适应性的PI控制驱动策略,再次,设计一种基于模糊控制的制动控制策略,在保证纵向车速跟踪精度的前提下,能避免车辆制动时的“前冲现象”,提高了舒适性。最后,通过Matlab与Carsim、Amesim的联合仿真验证了算法的有效性。

| Abstract: | First,a switching logic with adjustable threshold between switching buffers is designed.Then,a PI control driving strategy that is adaptive to vehicle speed changes is designed.Secondly,a braking control strategy based on fuzzy control is designed to avoid vehicle braking while ensuring the accuracy of longitudinal vehicle speed tracking.The"forward rush phenomenon"improves comfort.Finally,the effectiveness of the algorithm is verified by the joint simulation of Matlab,Carsim and Amesim. |
