车载人因协同仿真系统研究及实现

Research and Implementation of On-board Human Factors Collaborative Simulation System

为提高现代车路协同系统中人车联合测试能力,搭建车载人因协同仿真系统。运用分布式理论建立汽车模拟仿真联合平台,构建车载人因协同仿真系统,基于MQTT(message queuing telemetry transport)消息队列遥测传输协议,优化数据分发效率与数据采集效率。仿真实验表明:构建的车载人因协同仿真平台降低了参与实验HMI(human machine interface)子系统与主系统的耦合性,具有良好的鲁棒性和灵活性,分布式数据分发机制使多终端子系统埋点数据采集与数据融合效果大大提升,且可扩展以支持更多的车辆子系统和其他终端设备的仿真研究。

In order to improve the multi-vehicle evaluation and follow the trend of the Internet of Vehicles in modern vehicle-road collaborative system,an on-board human factors collaborative simulation system is built.Distributed theory is used to establish a joint platform for vehicle simulation,and an on-board human factors co-simulation system is built and MQTT network is used to optimize the data distribution mechanism and data collection mechanism.The simulation experiment shows that the built on-board human factor co-simulation platform reduces the coupling between the participating experimental subsystems and the main system,and has good robustness and flexibility.The distributed data distribution mechanism enables the multi-HMI subsystems to bury the point data collection and the data fusion effect is improved,and can be further used to support more simulation research of vehicle subsystems and other HMI terminal devices.
