The invention discloses a vehicle entering direction recognition method and system and a vehicle. The method comprises the steps that the first signal strength of a signal received by an antenna corresponding to each vehicle door is obtained in sequence; screening out a maximum value and a secondary maximum value in the first signal intensity; and when the difference value between the maximum value and the secondary maximum value exceeds a judgment threshold value, judging the direction of the antenna corresponding to the maximum value as the vehicle entering direction. The vehicle entering direction can be judged only through one node, the number of arranged nodes can be greatly reduced, the manufacturing cost is saved, the antenna only receives signals, the power consumption is low, and meanwhile, the static power consumption can be reduced only through supplying power to one node.
本申请公开了一种进入车辆方向识别方法、系统及车辆,包括:依次获取每个车门所对应的天线所接收信号的第一信号强度;筛选出第一信号强度中的最大值和次最大值;当所述最大值与次最大值的差值超过判定门限值时,将最大值对应的天线所在方向判定为进入车辆方向。利用本申请只需一个节点即可判定进入车辆方向,能够大大减少节点的布置数量,节约制造成本,而且天线仅接收信号,功耗低,同时,只需向一个节点供电,也可降低静态功耗。
