摘要:BD车载终端可实现对车辆运行信息的捕获,进而实现对车、人、环境三方面的状态监测。针对目前OBD产品功能单一的现状,设计并开发了一套多功能OBD车载终端设备。硬件平台基于英飞凌公司的XMC4500系列32位高性能处理器,配备了4G通信模块及WiFi模块,实现了车辆数据上传与无线网络环境覆盖。搭载了MPU-9250陀螺仪,实现对车辆的9轴运动检测,支持SDHC大容量数据的读写操作。为了增强用户的体验,增加了数字FM音频模块及胎压监测模块,可提高用户的驾驶感受。该设计可实现对车辆发动机参数的采集与上传,通过上位机平台对数据的算法计算,能够对驾驶行为及UBI保险业务提供参考依据。

Abstract:OBD vehicle terminal can realize the capture of vehicle operation information, and then realize the status monitoring of vehicle, human and environment. Aiming at the present situation of single function of OBD products, a set of multifunctional OBD vehicle terminal equipment is designed and developed. Based on Infineon′s XMC4500 series 32-bit high performance processor, the hardware platform is equipped with 4G communication module and WiFi module to realize vehicle data upload and wireless network environment coverage. It is equipped with the MPU-9250 gyroscope to realize the detection of the 9-axis motion of the vehicle and support the read and write operation of SDHC large-capacity data. In order to enhance the user′s experience, digital FM audio module and tire pressure monitoring module are added to improve the user′s driving experience. This design can realize the collection and upload of vehicle engine parameters, calculate the data through the algorithm of upper computer platform, and provide reference for driving behavior and UBI insurance business.

随着新能源及5G通信技术的发展,公路交通工具出现了重大变革,从传统的无网络燃油汽车逐步过渡到互联网电动汽车时代。车联网技术正是将传统燃油汽车推向互联网车辆的重要抓手,5G时代的到来赋予了车联网产业重要的发展机遇[1]。OBD车载终端产品利用对车辆工况的采集与分析,实现了车、人、环境三方面的整合。目前在该领域产品多基于以上三方面开展。文献[2]利用英飞凌公司的XC2000系列单元实现了对电动汽车行驶数据的采集,并构建了远程监控平台,实现对被测车辆的无线访问。文献[3]基于飞思卡尔MC9S12XE单元实现对电动汽车电机、电池等数据的采集,实现了全车4G信号覆盖等功能。文献[4]基于STM32F103单元配合速度传感器、振动传感器及WiFi和蓝牙通信技术,实现了对车辆行驶数据的采集,并通过上位机云服务器实现数据管理。其他相关文献研究思路基本相近[5-8],均围绕对车辆信息分析为基础,实现驾驶员及周边环境信息的获取。作为车载终端,除具备以上基本功能外,还应多方面考虑用户的驾驶体验。本文在构建车辆、人员及环境信息分析模型的基础上,增加了FM音频及胎压监测功能,以拓宽消费市场,满足更多用户需求。
