具体实施例
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
参照图1，示出了本申请实施例中的一种无线充电控制方法的步骤流程图，如图1所示，该控制方法具体可以包括以下步骤：
S101：获取连接到无线充电设备的终端设备的型号信息，其中，无线充电设备用于对终端设备进行无线充电；
本步骤中，无线充电设备可以是设置在车辆上的无线充电器，终端设备可以具有无线充电功能的手机，获取终端设备的型号信息的方法可以是通过获取终端设备的图像识别终端设备的型号，以手机为例，获取手机的图像信息，对手机的图像进行处理，并从图像中提取手机的形状、商标以及摄像头形状特征，然后从预先建立的数据库的样本进行匹配，从而确定最相似的样本型号为终端设备的型号信息。
S102：根据终端设备型号信息，确定对应的异物报警阈值；
本步骤中，不同型号的终端设备对应的异物报警阈值不同，例如iPhone12手机无线充电中增加了磁吸定位功能，定位磁铁和阵列式的磁环设计在手机充电线圈周围，进而若iPhone12手机与其他手机共用一套参数，容易触发报警条件，影响客户使用，因此需要针对不同型号的手机，确定对应的异物报警阈值。
S103：根据无线充电设备当前的Q值和异物报警阈值之间的大小关系，控制无线充电设备对终端设备的充电状态。
以终端设备为手机为例，手机的无线充电技术采用的是电磁感应式技术，本步骤中的Q值为电感Q值，也叫电感的品质因数，是衡量电感器件的主要参数，是指电感器在某一频率的交流电压下工作时，所呈现的感抗与其等效损耗电阻之比，也就是说，损耗越大，Q值越小。
当终端设备和无线充电设备之间存在异物时，相当于在无线充电设备的发射线圈上并联了电阻负载，进而使得Q值减小；因此，通过比较无线充电 设备当前的Q值和异物报警阈值之间的大小关系，能够在一定程度上反映出无线充电设备与其终端设备之间是否存在异物，并且根据是否存在异物而控制无线充电设备对终端设备的充电状态。
从而，需要对终端设备进行充电时，无线充电设备先获取与之连接的终端设备的型号信息，根据终端设备型号信息，确定对应的异物报警阈值，然后根据无线充电设备当前的Q值和异物报警阈值之间的大小关系，控制无线充电设备对终端设备的充电状态，进而能够根据手机型号的不同，调用与之对应的异物报警阈值，减少因为终端设备型号的差别而影响正常充电，从而能够便于在一定程度上提高无线充电设备的适应性以及提高无线充电设备的检测准确性。
实施例二
参照图2所示，示出了本申请实施例的一种无线充电控制方法的步骤流程图，如图2所示，本申请实施例二提供了一种无线充电控制方法具体可以包括以下步骤：
S201：检测无线充电设备上是否连接终端设备信息；若存在终端设备，执行S202；
本步骤首先判断无线充电设备上是否连接有终端设备，检测终端设备是可以使用传感元件，例如压力传感器或者红外传感器。
S202：获取连接到无线充电设备的终端设备的型号信息，其中，无线充电设备用于对终端设备进行无线充电；
在检测到无线充电设备上连接有终端设备后，获取终端设备的型号信息，获取方法如S101中的获取方法。
S203：获取与终端设备的型号信息对应的第一目标查询表，第一目标查询表包括多个终端设备的样本型号各自对应的异物报警阈值；
本步骤中，第一目标查询表内预先存储有多个终端设备的样本型号各自对应的异物报警阈值，关于获取第一目标查询表的方法，可以从本地存储中获取，也可以通过联网的方式进行获取。
S204：从第一目标查询表中获取与当前终端设备的型号信息对应的异物报警阈值；
本步骤中，根据与无线充电设备连接的当前终端设备的型号，从第一目 标查询表中调用于对应的异物报警阈值。
S205：获取无线充电设备当前的Q值；
本步骤中，无线充电设备当前的Q值可以通过计算获得。
S206：根据无线充电设备当前的Q值和异物报警阈值之间的大小关系，控制无线充电设备对终端设备的充电状态，具体包括：
若当前的Q值小于异物报警阈值，控制无线充电设备对终端设备的停止匹配并进行报警；
若当前的Q值大于等于异物报警阈值，控制无线充电设备对终端设备的进行匹配并进行充电。
具体判断流程参照图3所示，由于损耗越大，Q值越小，因此，若在当前的Q值小于异物报警阈值时，判断为有异物，进而停止无线充电设备与终端设备的匹配，并且进行报警，报警的方式可以是文字、声音或者灯光，以提醒客户存在无线充电设备与终端设备之间存在异物。
若在当前的Q值大于等于异物报警阈值时，控制无线设备与终端设备进行匹配并开始为终端设备充电。
在其他实施方式中，在无线充电设备对终端设备开始充电后，仍然持续获取无线充电设备当前的Q值，并与该型号的终端设备对应的异物报警阈值进行比较，从而能够检测充电过程中是否存在异物。
在一个可行的实施方式中，当前的Q值大于等于异物报警阈值，控制无线充电设备对终端设备的进行匹配并进行充电，在对终端设备充电的过程中，方法还包括：
S207：根据终端设备型号信息，确定对应的功率损耗阈值；具体为：
获取与终端设备的型号信息对应的第二目标查询表，第二目标查询表包括多个样本型号各自对应的功率损耗阈值；
从第二目标查询表中获取与当前终端设备的型号信息对应的功率损耗阈值。
本步骤中，第二目标查询表内预先存储有多个终端设备的样本型号各自对应的功率损耗阈值，根据与无线充电设备连接的当前终端设备的型号，从第二目标查询表中调用于对应的功率损耗阈值。
S208：获取无线充电设备的工况信息；
在本实施方式中，无线充电设备的工况信息包括无线充电设备的当前发射功率，以及终端设备的接收功率，其中，无线充电设备可以接收到终端设备反馈的接收功率。
S209：根据无线充电设备的工况信息以及功率损耗阈值之间的大小关系，控制无线充电设备对终端设备的充电状态，具体包括：
具体判断过程参照图4所示，计算无线充电设备的当前发射功率与终端设备的接收功率之间的损耗功率；具体地，损耗功率＝发射功率-接收功率；
若损耗功率小于功率损耗阈值，控制无线充电设备对终端设备继续充电；当终端设备的电量达到一定程度，例如手机的电量为90％以上后，无线充电设备能够减小充电功率。
若损耗功率大于等于功率损耗阈值，控制无线充电设备对终端设备停止充电并进行报警；报警的方式可以是文字、声音或者灯光，以提醒客户存在无线充电设备与终端设备之间存在异物。
从而在充电的过程中，除了利用Q值来判断异物，还可以通过损耗功率与功率损耗阈值对充电过程中的异物进行检测，并且对用户进行报警提醒，在一定程度上减少了异物对充电的影响。
