车载数据无线传输及其平视显示设计

随着社会经济的不断发展,汽车保有量逐年增加,车载数据无线传输及其平视显示技术作为一种行之有效的汽车辅助驾驶技术,不仅能够将车载数据无线传输至客户端,而且能够使驾驶员在平视范围内获取到汽车的实时运行数据和状态,提高了驾驶的安全性,改善了驾驶舱的人机交互体验。根据目前国内外车载数据无线传输及其平视显示技术的研究,提出了一套符合人机交互设计方法的车载平视显示器的设计原则并设计出了界面原型,以OBD-II、Arduino Mega2560 R3开发板、USART HMI串口屏和ESP8266-01模块为基础,实现了车载数据的无线传输及其平视显示。最后,通过OBD-II模拟器仿真测试和实车测试,验证了系统在功能上的正确性以及在性能上的可靠性和实用性。

Wireless transmission of vehicle data and its head up display

With the continuous development of social economy, the number of vehicle ownership is increasing year by year, the wireless transmission of vehicle data and its head up display technology, as an effective vehicle assisted driving technology, can not only transmit the vehicle data wirelessly to the client, but also enable the driver to obtain the real-time operation data and state of the vehicle within the range of the head up, which improves the safety of driving and improves the human-computer interaction experience of the cockpit. According to the research of wireless transmission of vehicle data and its head-up display technology at home and abroad, a set of design principles of vehicle head-up display conforming to the human-computer interaction design method is proposed and the interface prototype is designed. Based on the OBD-II, Arduino Mega2560 R3 development board, USART HMI serial screen and ESP8266-01 module, the wireless transmission of vehicle data and its head up display are realized. Finally, through the OBD-II Simulator simulation test and real vehicle test, the function correctness of the system and the reliability and practicability in performance are verified.
