The invention provides a keyless control vehicle system and method. The keyless control vehicle method comprises the following steps: receiving a radio frequency signal sent by a radio frequency transmitter; acquiring a signal of personnel in the vehicle; determining the distance between the radio frequency transmitter and the detection antenna according to the radio frequency signal, judging whether the distance between the radio frequency transmitter and the detection antenna is greater than a first distance or not, judging whether a person is in the vehicle or not, and if the distance between the radio frequency transmitter and the detection antenna is greater than the first distance and no person is in the vehicle, locking the vehicle and counting down; aiming at the situation that the radio frequency signal emitted by the radio frequency emitter is still received in the countdown process, the distance between the radio frequency emitter and the detection antenna is determined according to the radio frequency signal, whether the distance between the radio frequency emitter and the detection antenna is smaller than a preset second distance or not is judged, and if the distance between the radio frequency emitter and the detection antenna is smaller than the preset second distance, counting is conducted. The vehicle is unlocked. The invention has the advantages that the vehicle is locked after being away from the vehicle, and the vehicle is unlocked when being close to the vehicle.
本发明提供一种无钥匙控制车辆系统及方法,包括以下步骤:接收射频发射器发出的射频信号;获取车辆内部人员信号;根据射频信号确定射频发射器与探测天线之间距离,判断射频发射器与探测天线之间距离是否大于第一距离,判断车辆内部是否有人,若射频发射器与探测天线之间距离大于第一距离且车辆内部无人,车辆上锁,进行倒计时;针对倒计时过程中,仍接收射频发射器发出的射频信号,根据射频信号确定射频发射器与探测天线之间距离,判断射频发射器与探测天线之间距离是否小于预设的第二距离,若射频发射器与探测天线之间距离小于预设的第二距离,车辆解锁。如上所述,具有以下有益效果:远离车辆后车辆上锁,靠近车辆时车辆解锁。
