摘　　要：本文基于模型预测控制原理设计了上层控制器,用来决策期望加速度以实现良好的跟车效果,并将期望加速度变化作为优化条件之一引入代价函数中,目的是为了更有效的优化油耗和乘坐舒适性,最后利用Simulink和CarSim的联合仿真验证所提出的控制器。从结果可以看到所设计的控制器能够很有效的控制跟随车辆跟随领航车迅速做出一系列加减速机动,可以在相同的道路条件下使车辆以更小的车间距保持队列行驶来增加道路容量,同时能降低油耗。通过加速度的变化结果可以看到燃油车的换挡操作会造成加速度的突变从而影响乘坐舒适。In order to solve the problems of traffic accidents,traffic congestion and air pollution caused by the increasing number of motor vehicles,cooperative adaptive cruise control has become a hot research topic in the field of intelligent transportation.In this paper,the upper-level controller is designed based on the model predictive control principle to decide the desired acceleration to achieve good following effect,and the desired acceleration variation is introduced into the cost function as one of the optimization conditions for the purpose of optimizing fuel consumption and ride comfort more effectively,and finally the proposed controller is verified using the joint simulation of Simulink and CarSim.From the results,it can be seen that the designed controller can effectively control the following vehicle to follow the pilot car to make a series of acceleration and deceleration maneuvers rapidly,which can make the vehicle to keep the queue driving with smaller workshop distance to increase the road capacity under the same road conditions,and can reduce the fuel consumption at the same time.The result of the acceleration change shows that the shift operation of the fuel car can cause sudden changes in acceleration and thus affect the ride comfort.
