The invention provides an automobile digital key turn-around judgment method and system, a medium and equipment. The method comprises the following steps that S1, an RSSI value N is recorded without shielding at a locking distance; s2, recording an RSSI value M in a turn-around manner at a locking distance; s3, calculating a turn-around change RSSI value X = M-N; s4, self-building a model K; s5, w is adjusted according to the credibility of P, and P is selected from a newly-driven vehicle; and S6, dynamically determining a locking value through the self-built model K. Through a multi-dimensional fusion mode, the situation that the digital key turns back in a specific area of the vehicle and is directly switched to another state is solved; the problem that the unlocking area and the locking area are overlapped after the automobile digital key turns around to shield the RSSI value at some positions is solved; and the difference of unlocking and locking distances under various attitudes is reduced.
本发明提供了一种关于汽车数字钥匙转身判断方法、系统、介质及设备,所述方法包括如下步骤:步骤S1:在闭锁距离无遮挡记录RSSI值N;步骤S2:在闭锁距离转身记录RSSI值M;步骤S3:计算转身变化RSSI值X=M‑N;步骤S4:自建模型K;步骤S5:w因P的可信度调整,P选取刚出车内;步骤S6:通过自建模型K动态确定落锁值。本发明通过多维度融合方式,解决了数字钥匙在车辆特定区域转身直接切换到另外一种状态的情况;解决了汽车数字钥匙在某些位置转身遮挡RSSI值之后开锁和闭锁区域重叠的问题;拉近了各种姿态下解、闭锁距离的差异。
