基于MATLAB的智能网联汽车仿真分析

The Simulation Analysis of Intelligent Networked Vehicles Based on MATLAB

文章利用MATLAB自动驾驶工具箱进行仿真,为智能网联汽车的正常运行提供可靠的数据支撑。对MATLAB场景搭建方式进行介绍,详细说明了场景搭建所用到的道路、参与者和传感器生成函数的用法。使用工具箱中的汽车纵向仿真模型构建了Simulink仿真系统,并通过阶跃输入来设定汽车的跟踪速度,对汽车在加速和减速过程中的响应情况进行了仿真分析,更加清晰地反映出汽车在进行速度跟踪时的加减速情况和最终的速度变化情况。

The MATLAB autopilot toolbox is used for simulation to provide more reliable data support for the normal operation of intelligent networked vehicles.This paper introduces the scene building method of MATLAB,and explains in detail the road,participants and the usage of sensor generating function used in the scene building.Simulink simulation system is built by using vehicle longitudinal simulation model in toolbox,and the vehicle tracking speed is set by step input,and the response of vehicle during acceleration and deceleration is simulated.More clearly reflect the car in the speed tracking of the acceleration and deceleration and the final speed changes.
