The invention discloses a method for controlling a vehicle based on a key moving track, which comprises the following steps of: S1, driving all vehicle-mounted antennas in a certain sequence to sequentially transmit a key position measurement request and a measurement pulse signal; s2, obtaining the distance between the key and each antenna according to a field intensity value sequence returned by the key and a field intensity value-distance relationship, then positioning the position of the key based on a three-ball positioning principle, and judging which triple overlapping area the key is located in; the triple overlapping area is an overlapping area of detection ranges of at least three antennas; s3, any three antennae corresponding to the triple overlapping area where the key is located are controlled to circularly send key position measurement requests and measurement pulse signals in a certain sequence, the positions of the key in different pulse emission cycles are determined according to a field intensity value sequence returned by the key, and then the moving track of the key is determined; and S4, when it is detected that the key passes through the set moving track within a certain time, outputting a vehicle control signal corresponding to the moving track.

    本发明公开了一种基于钥匙移动轨迹控制车辆的方法,包括以下步骤,S1、以一定顺序驱动车载的所有天线依次发射钥匙位置测量请求和测量脉冲信号;S2根据钥匙返回的场强值序列与场强值‑距离关系,得到钥匙与各天线的距离,而后基于三球定位原理,定位钥匙位置,并判断钥匙位于哪个三重重合区域;所述三重重合区域为至少三根天线的探测范围的重合区域;S3控制钥匙所在的三重重合区域对应的任意三根天线以一定顺序循环发送钥匙位置测量请求和测量脉冲信号,根据钥匙返回的场强值序列确定钥匙在不同脉冲发射循环中的位置,进而确定钥匙的移动轨迹;S4、当检测到钥匙在一定的时间内经过设定的移动轨迹时,输出与该移动轨迹对应的车辆控制信号。
