摘要

车车通信已经成为智能车辆获取外界信息的重要手段

而通信延时将严重影响车辆之间信息传输的准确性.为了减小通信延时问题对车车通信链路产生的不利影响

有必要对延时进行一定的补偿.本文将首先基于当前统计模型对前方车辆的运动状态进行建模

然后利用加速度方差自适应卡尔曼滤波模型对前车运动状态进行估计

在此基础上增加延时补偿算法

对前车的位置、速度信息进行一定的补偿; 最后

通过Matlab软件对本文所提出的延时补偿方法进行仿真验证

仿真结果显示了本文所述方法的有效性.

Abstract

Vehicle-vehicle communication(v2v) has become an important means for intelligent vehicles to obtain external information

and the communication delay directly affects the accuracy of the received information.In order to reduce the adverse effect of communication delay on the communication link

it is necessary to make some compensation for the delay. This paper first modelling the vehicle motion based on the current statistical model

and then based on the adaptive kalman filter model

the vehicle motion state is predicted

and then the delay compensation algorithm is used to compensate the received information.At last

the delay compensation algorithm is simulated by Matlab software

and the simulation results show the effectiveness of the proposed algorithm.
