The Research and Development of Time-sharing Leasing Vehicle Terminal for Electric Vehicle based on Acoustic Communication Technology
With the rapid development of time-sharing leasing business model for electric vehicles, remote control as the most important part of the all-service process of time-sharing leasing, the degree of its rapid response directly affects the integrity of business process and the sense of user experience. At present, electric vehicles terminals mainly adopt 3G, LTE, 4G, LTE, GPRS and other traditional wireless communication methods, and upload data to the platform management center in real time, and receive the remote control command from the platform management center by them. However, in the weak signal area, the response of the electric vehicle terminal will become longer and slower, which will directly affect the user experience and the management degree of the electric vehicle management platform management center. Therefore, this paper uses the acoustic communication technology as an auxiliary way, puts forward the "ASK FSK" integrated modulation methods, and combines with the "anti interference technology of wheat double entry". Finally, with high ability of anti-noise acoustic communication function of time-sharing leasing vehicle terminal for electric vehicles is developed, which achieves mobile phone sound wave to control vehicle. This work lays firm technical support for keeping the fluency and integrity of the all-service process of time-sharing leasing.
