【摘要】：随着电动汽车分时租赁商业模式业务蓬勃发展,远程控制作为分时租赁全业务流程中最重要环节,其快速响应程度直接影响全业务流程完整性和用户体验度。目前,电动汽车车载终端主要采用3G LTE、4G LTE、GPRS等无线通信方式,实时向平台管理中心上传车辆运营情况,并接收由平台管理中心下发的远程控制指令。但是在信号恶劣地区,其电动汽车车载终端会出现时延长、响应慢的现象,直接影响用户体验度和平台管理中心对电动汽车的管理力度。为此,文中引入声波通信技术作为辅助通信方式,采用"ASK+FSK"复合调制方式,并结合"双麦录入"的抗干扰技术,研制出具有高抗噪性声波通信功能的电动汽车分时租赁车载终端,实现手机声波对车辆的控制,为保障分时租赁全业务流程流畅性和完整性奠定坚实的技术支撑。
[Abstract]:With the rapid development of electric vehicle time-sharing business model, remote control is the most important part of time-sharing business process, and its rapid response directly affects the integrity of the whole business process and the degree of user experience. At present, the vehicle terminal of electric vehicle mainly adopts the wireless communication mode such as 3G LTEN 4G LTEN GPRS, uploads the vehicle operation to the platform management center in real time, and receives the remote control instruction from the platform management center. However, in the area of bad signal, the electric vehicle terminal will appear long and slow response, which directly affects the user experience and the management of the platform management center to the electric vehicle. For this reason, acoustic communication technology is introduced as auxiliary communication mode, "ASK FSK" compound modulation mode is adopted, and anti-jamming technology of "double wheat input" is combined. An electric vehicle time-sharing vehicle terminal with high anti-noise acoustic communication function is developed to realize the control of mobile phone acoustic wave to the vehicle and lay a solid technical support for ensuring the fluency and integrity of the whole business process of time-sharing lease.
