基于汽车车辆跟随距离智能控制仿真

Simulation Based on Intelligent Control of Vehicle Following Distance

研究汽车车辆纵向跟随距离智能控制,针对车辆跟随距离控制在保证车队稳定行驶的前提下,要求在保证车队安全的同时增大交通流量从而进一步需要实现固定车间距等难点,提出一种基于车车通信的滑模变结构智能车辆固定车距跟随控制算法。利用Matlab/Simulink软件建立智能车辆跟随模型,同时搭建基于ZigBee的无线通信系统和智能微缩车实验平台,进一步验证了算法的有效性。由仿真与实验结果表明,上述控制方法能实现适宜的固定车间距,保证车队的稳定运行控制,为更多智能车辆的ACC队列的控制研究提供了准确理论指导与实验参考。

In the paper, a vehicle constant distance following control algorithm based on sliding mode variable structure for inter-vehicle communication was proposed. The model of intelligent vehicle following vehicle was estab- lished based on Matlab/Simulink. And the wireless communication system based on ZigBee and experimental platform intelligent micro vehicle was established. The results from simulation and experiments show that the proposed method provides appropriate following distance. Therefore, it provides an accurate theoretical guidance and experimental ref- erence for the control of the ACC queue for more intelligent vehicles.
