摘　　要：针对智能网联汽车对通信带宽与速率的要求日渐提高而CAN总线不能满足的问题,提出了将MQTT协议用于车内通信的方案。对其优势进行了分析,并设计了基于MQTT协议的车载无线局域网通信系统。用户可通过Web端监控各客户端连接情况,对客户端进行实时管理,也可使用控制终端对各执行器与传感器进行控制。进行了传感器与控制终端,控制终端与执行器的通信实验验证。实验结果表明,该系统运行良好,设备之间通信可靠,具有数据准确、稳定性强和可靠性高的优点,可满足实际车内通信的需求。In view of the increasing requirements of communication bandwidth and speed of intelligent networked vehicles and the ina-bility of CAN bus to meet them,a scheme for using MQTT protocol for in-vehicle communication is proposed.Its advantages are ana-lyzed and an in-vehicle wireless LAN communication system based on MQTT protocol is designed.Users can monitor the connection sta-tus of each client through the Web terminal,manage the client in real time,and can also use the control terminal to control the actuators and sensors.The communication experiments between the sensor and the control terminal,the control terminal and the actuator are veri-fied.Experimental results show that the system works well,the communication between the equipment is reliable,and it has the advanta-ges of accurate data,strong stability and high reliability,which can meet the needs of actual in-vehicle communication.
