With the rapid development of the time-sharing rental business model for electric vehicles,\nthe remote control speed of the electric vehicle terminals device, as the most important part of the\nwhole time-sharing rental business process, affects directly the integrity of the business process\nand the using feelings of consumers. However, the traditional remote control system by using\ngeneral packet radio service (GPRS), 3G, and 4G long term evolution (LTE) wireless communication\nmethods responds longer and slower in weak signal area, which directly affects the userâ??s feeling and\nmanagement strength of platform management center for the electric vehicle. Therefore, in this paper,\n(1) the acoustic communication technology as an auxiliary communication method is introduced in\nthe novel vehicle terminal; (2) In order to increase the anti-noise ability, â??amplitude-shift keying (ASK)\n+ frequency-shift keying (FSK)â? compound modulation and â??double microphone inputâ? technology\nare used in the vehicle terminal, which develops a novel vehicle terminal with the high anti-noise\nacoustic wave communication function for the electric vehicle in time-sharing rental mode; and (3)\nthe mobile phone acoustic waves can be used by the proposed vehicle terminal to control the door of\nelectric vehicle, which provides a firm technical support for ensuring the fluency and completeness\nof the whole process. Tests prove that the acoustic communication technology of the novel vehicle\nterminal can realize the rapid response of the vehicle terminal, which effectively solves the problem of\na prolonged and slow response in the vehicle terminal of the electric vehicle in the weak signal area.
