新能源汽车远程监控标定的通信系统设计
|
摘要
汽车在出厂时参数标定便固定不变,但车辆长期运行会导致车辆控制参数不适应一些变化。随着车联网技术的发展,实现远程监控标定成为可能。基于新能源汽车设计了汽车参数远程监控标定的通信系统,实现了电控单元和云平台之间的数据交换。首先对外部网络和内部网络的通信协议进行设计,然后通过LTE模块发送AT指令控制其接入网络,实现与云平台监控中心的连接与数据传输,最后通过命令解析程序,对云平台监控中心发送的命令进行校验、解析并完成对应的命令操作。测试表明,该通信系统实现了电控单元和云平台之间的数据实时交换。
The calibration of existing vehicle parameters is fixed at the factory.With the rapid development of vehicle networking technology,it is possible to realize remote monitoring and calibration.Based on the new energy vehicle,a communication system for remote monitoring and calibration of vehicle parameters is designed,and the data exchange between the ECU and the cloud platform is realized.The paper first designs the communication protocol of the external network and the internal network,then transmits the AT instruction through the LTE module to control its access network,and realizes the connection and the data transmission with the cloud platform monitoring center.Finally,through the command analysis program,the received commands of the cloud platform monitoring center are checked,analyzed,and the corresponding command operation is completed.The test shows that the communication system designed in this paper can realize the data exchange between the electronic control unit and the cloud platform in real time.
