The invention relates to the technical field of automobile control, in particular to a radio frequency receiving device of a vehicle and the vehicle thereof.The device comprises a radio frequency receiving assembly used for modulating and demodulating a received ultrahigh frequency (UHF) key signal and/or a UHF tire pressure signal to obtain a first demodulated signal; the Bluetooth receiving component is used for modulating and demodulating the received Bluetooth radio frequency signal to obtain a second demodulated signal; and the signal processing assembly is used for sending the first demodulation signal to a CAN communication network in the vehicle, modulating verification data obtained by the second demodulation signal to generate a response signal, and sending the response signal to a preset Bluetooth terminal through the Bluetooth receiving assembly. Therefore, the problems of difficulty in selection of module arrangement positions and high vehicle cost caused by related technologies are solved, reception of keyless system radio-frequency signals, tire pressure radio-frequency signals and mobile phone Bluetooth key signals is realized, the structure is small and exquisite, arrangement is convenient, remote control distance and tire pressure receiving rate can be improved, and the overall cost of the system is reduced.

    本申请涉及汽车车控技术领域,特别涉及一种车辆的射频接收装置及其车辆,其中,装置包括:射频接收组件,用于调制并解调接收到的特高频UHF钥匙信号和/或UHF胎压信号,得到第一解调信号;蓝牙接收组件,用于调制并解调接收到的蓝牙射频信号,得到第二解调信号;信号处理组件,用于将第一解调信号发送车辆内的CAN通信网络,并调制由第二解调信号得到的校验数据生成应答信号,并通过蓝牙接收组件将应答信号发送至预设蓝牙终端。由此,解决了相关技术会造成模块布置位置难选,整车成本较高的问题,实现无钥匙系统射频信号、胎压射频信号和手机蓝牙钥匙信号的接收,结构小巧,布置方便,同时还能提升遥控距离和胎压接收率,降低系统整体成本。
