具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请实施例可应用于各种类型的通信系统。图1为本申请实施例提供的一种应用场景示意图。如图1所示的通信系统，主要包括网络设备11和终端12。
其中，1)网络设备11可以是网络侧设备，例如，无线局域网(Wireless Local Area Network，WLAN)的接入点(Access Point,AP)、4G的演进型基站(Evolved Node B，eNB或eNodeB)、下一代通信的基站，如5G的新无线接入技术(New Radio Access Technology，NR)基站(next generation Node B，gNB)或小站、微站，还可以是中继站、发送和接收点(Transmission and Reception Point，TRP)、路边单元(Road Side Unit,RSU)等。在本实施例中，不同通信制式的通信系统中的基站不同。为了区别起见，将4G通信系统的基站称为长期演进(Long Term Evolution，LTE)eNB，5G通信系统的基站称为NR gNB，既支持4G通信系统又支持5G通信系统的基站称为演进型长期演进(Evolutional Long Term Evolution，eLTE)eNB,这些名称仅为了方便区别，并不具有限制意义。
2)终端12又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备、具有车与车(vehicle to vehicle，V2V)通信能力的车辆等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。

需要说明的是，图1所示的通信系统中所包含的终端12的数量和类型仅仅是一种举例，本申请实施例并不限制于此。例如，还可以包括更多的与网络设备11进行通信的终端12，为简明描述，不在附图中一一描述。此外，在如图1所示的通信系统中，尽管示出了网络设备11和终端12，但是该通信系统可以并不限于包括网络设备11和终端12，例 如还可以包括核心网节点或用于承载虚拟化网络功能的设备等，这些对于本领域技术人员而言是显而易见的，在此不一一赘述。
另外，本申请实施例不仅可应用于4G无线通信系统、车对外界(vehicle to everything，V2X)通信系统、设备到设备(Device-to-Device,D2D)通信系统、LTE的后续演化等通信系统，还可应用于下一代无线通信系统,即5G通信系统，以及应用于未来可能出现的其他系统,例如下一代的wifi网络、5G车联网等。
需要说明的是，随着通信系统的不断演进，未来可能出现的其他系统中，上述各个网元的名称可能会发生变化，在这种情况下，本申请实施例提供的方案同样适用。
图2为本申请实施例提供的另一种应用场景的示意图。如图2所示，A、B、C、D分别表示车辆20内的终端，箭头21所示的方向表示车辆20的车头朝向，22表示车辆20的方向盘。在本实施例中并不限定车辆20内座椅的数量，也不限定车辆20内终端的数量。车辆20内座椅的数量和车辆20内终端的数量可以相同，也可以不同。车辆20内座椅的数量和车辆20内用户的数量可以相同，也可以不同，另外，本实施例也不限定每个用户可携带的终端的数量。另外，通常情况下车辆内安装有车载设备，该车载设备例如可以是如图2所示的车机。车机大多安装在中控台里面，车机可包括主机和屏幕，在一些场景中，车机的主机和屏幕是在一起的，而在一些场景中，车机的主机和屏幕是分离的。其中，中控台是指驾驶室内正副驾驶前面的工作台，该工作台是仪表盘、空调、音响面板、储物盒、以及气囊等装置的载体。车机可以通过有线方式或无线方式与车内的终端通信连接，并为终端提供服务，例如，音乐播放服务、导航服务等。例如，终端A、终端B、终端C、终端D都在历史时间与该车机连接过，当前该车机确定车辆20内存在终端A、终端B、终端C、终端D，进一步，选择终端A、终端B、终端C、终端D中最近一次连接过的终端作为当前需要连接的终端，例如，终端D是与该车机最近一次连接过的终端，则该车机确定终端D是当前需要连接的终端，并与终端D建立连接。也就是说，终端D的用户可能并不是本次的驾驶员，但是由于车机自动选择最近一次连接过的终端进行连接，而真正有连接需求的用户，例如，终端A的用户是本次的驾驶员，却只能选择手动连接车机，给驾驶员带来较大的麻烦。针对该问题，本实施例提供了一种通信连接方法，下面结合实施例对该通信连接方法进行详细的描述。
图3为本申请实施例提供的一种通信连接方法流程图。该方法可适用于车载设备，例如图2所示的车机。如图3所示，本实施例所述的通信连接方法包括如下步骤：
S301、检测车内至少一个终端发送的无线信号。
在本实施例中，车机和车内的至少一个终端通过无线方式进行连接，此处并不对该无线方式进行限定，例如，可以是蓝牙、无线保真(Wireless Fidelity，WiFi)、4G网络、5G网络等。此处以蓝牙为例进行示意性说明，车内的至少一个终端可安装有蓝牙模块，该蓝牙模块可设置有至少一个天线，并且支持能够对终端进行角度定位和距离定位的通信协议，例如，蓝牙5.1通信协议。需要说明的是，当车内存在多个终端时，并不要求该多个终端都安装有支持蓝牙5.1通信协议的蓝牙模块，也就是说，该多个终端可以部分安装有支持蓝牙5.1通信协议的蓝牙模块，部分未安装支持蓝牙5.1通信协议的蓝牙模块。具体的，安装有该蓝牙模块的终端可以实时的广播无线信号，使得车机可检测车内至少一个终端广播的无线信号。
S302、根据所述无线信号，确定所述至少一个终端相对于所述车载设备的位置信息。
该位置信息包括角度和距离。该车机可根据每个终端广播的无线信号，确定该终端相对于车机的角度和距离。具体的，该车机可通过蓝牙5.1版本的到达角(Angle-of-Arrival，AOA)或发送角(angle of departure,AOD)技术检测终端相对于车机的角度。该车机可通过终端广播的无线信号的信号强度检测终端相对于车机的距离，或者通过蓝牙5.1版本的AOA或AOD技术检测终端相对于车机的距离，或者通过终端广播的无线信号的信号强度、以及AOA或AOD技术检测终端相对于车机的距离。
可以理解的是，终端相对于车载设备的角度和距离是终端的定位信息即位置信息的一种示例，终端的位置信息还可以是其他信息，此处不再赘述。另外，通过AOA或AOD技术检测终端相对于车载设备的位置信息，例如角度和距离，只是对终端进行定位的一种方式，还可以采用其他的定位方法对终端进行定位。
S303、根据所述至少一个终端相对于所述车载设备的位置信息，确定所述至少一个终端中的驾驶员终端，并与所述驾驶员终端进行通信连接。
如图4所示，终端A和终端B是车内的终端，终端A和终端B实时发送AOA广播信号，车机在上电和启动之后，可接收到一个或多个终端发送的AOA广播信号，并根据终端A发送的AOA广播信号，计算终端A相对于车机的AOA和距离，以及根据终端B发送的AOA广播信号，计算终端B相对于车机的AOA和距离。进一步，根据终端A相对于车机的AOA和距离、以及终端B相对于车机的AOA和距离，确定终端A和终端B中哪个终端相对于车机的AOA和距离在需求范围内，例如，终端A相对于车机的AOA和距离在需求范围内，则该车机确定终端A为驾驶员终端，并与该终端A进行通信连接。
本实施例通过检测车内至少一个终端发送的无线信号，根据至少一个终端发送的无线信号，确定至少一个终端相对于车载设备的位置信息，并根据至少一个终端相对于所述车载设备的位置信息，确定至少一个终端中的驾驶员终端，并与驾驶员终端进行通信连接，相比于现有技术中车载设备优先与最近一次连接过的终端自动连接，可避免与车载设备最近一次连接过的终端不是本次驾驶员终端时该车载设备依然与该终端连接的问题，也就是说，车载设备每次只与驾驶员终端连接，即车载设备每次只与最需要连接该车载设备的终端进行连接，减少了驾驶员的连接操作，从而提高了驾驶员终端连接车载设备的便捷性。
上述实施例提到了车机可通过AOA或AOD技术检测终端相对于车机的角度。下面对该检测过程进行详细介绍。具体的，采用AOA或AOD技术检测终端相对于车机的角度时，需要车机和终端满足如下表1所示的硬件条件和软件条件：
表1
Figure PCTCN2020115446-appb-000001
通过表1可知，当采用AOA技术检测终端相对于车机的角度时，需要车机具有2根或2根以上天线，并支持蓝牙5.1版本的通信协议；终端需要具有单天线，并支持蓝牙5.1版本的通信协议。当采用AOD技术检测终端相对于车机的角度时，需要车机具有单天线，并支持蓝牙5.1版本的通信协议；终端需要具有2根或2根以上天线，并支持蓝牙5.1版本的通信协议。下面以AOA为例，介绍终端相对于车机的角度的检测方法。
如图5所示，天线1和天线2表示车机中的天线，无线信号为终端发送的信号，d表 示天线1和天线2之间的距离，L表示光程差。由于终端相对于天线1和天线2的距离不同，因此，终端发送的无线信号分别到达天线1和天线2时的相位不同，此处，可根据该无线信号到达天线1和天线2的相位差来计算终端相对于车机的角度，该角度具体可以是如图5所示的到达角θ，
Figure PCTCN2020115446-appb-000002
即
Figure PCTCN2020115446-appb-000003
另外，将该无线信号到达天线1和天线2的相位差记为
Figure PCTCN2020115446-appb-000004
相位差
Figure PCTCN2020115446-appb-000005
光程差L、该无线信号的波长λ之间的关系如下公式(1)所示：
Figure PCTCN2020115446-appb-000006
根据公式(1)可计算出光程差L，即
Figure PCTCN2020115446-appb-000007
进一步，将

代入
Figure PCTCN2020115446-appb-000009
可得
Figure PCTCN2020115446-appb-000010
到达角θ即为终端相对于车机的角度。同理，当车内存在多个终端时，可计算出其他终端相对于车机的角度，此处不再一一赘述。
可以理解的是，在其他实施例中，车机还可以包括2个以上的天线，例如，3个或更多的天线，在这种情况下，采用如图5所示的方法，根据每2个天线可计算出一个终端相对于车机的角度，如此可计算出多个终端相对于车机的角度，根据多个终端相对于车机的角度可计算出较为精准的终端相对于车机的角度。另外，天线可以集成在车机内部，也可以不集成在车机内部，而是分布在车内的其他位置，例如，车的顶棚。当天线不集成在车机内部时，车机和天线只需通信连接即可，也就是说，天线接收到终端发送的无线信号后，通过天线和车机之间的通信链路发送给车机。在一些实施例中，还可以是部分天线集成在车机内，部分天线分布在车内的其他位置。
在上述实施例的基础上，在计算终端相对于车机的距离时，具体可采用如下几种可行的实现方式：
作为一种可行的实现方式：通过终端广播的无线信号的信号强度检测终端相对于车机的距离。
如图6所示，车机接收终端发送的无线信号，并检测接收信号强度指示(Received Signal Strength Indication，RSSI)。进一步，车机通过滑动平均法(moving average)对RSSI进行处理，预测RSSI的变化趋势，具体的，通过重近轻远原则，对于当前时刻检测到的RSSI给予较大权重数，对于历史时刻检测到的RSSI给予较小权重数，目的在于优化近期数据的作用，弱化远期数据的影响。进一步，通过卡尔曼滤波(Kalman Filter)消除RSSI中的误差。另外，终端发送的无线信号中可包括距离路径损耗模型的标识信息，车机可根据该标识信息对应的距离路径损耗模型、以及消除误差后的RSSI计算出终端相对于车机的距离。其中，用于执行滑动平均法的滑动平均模块和执行卡尔曼滤波的卡尔曼滤波器可以集成在车机内部，也可以集成在远程服务器中。当滑动平均模块和卡尔曼滤波器集成在远程服务器时，车机需要将其检测到的RSSI发送给远程服务器，由远程服务器根据RSSI计算出终端相对于车机的距离，并由远程服务器将该距离发送给车机。
作为另一种可行的实现方式：通过AOA或AOD技术检测终端相对于车机的位置，该位置包括距离和方向。
如图7所示，车机上部署有蓝牙模块1和蓝牙模块2，其中，每个蓝牙模块包括至少2个天线，每个蓝牙模块和终端需要满足如上表1所示的硬件条件和软件条件，此处不再赘述。D表示蓝牙模块1和蓝牙模块2之间的距离，以AOA为例，根据图5所示的方法可计算出终端的无线信号分别到达蓝牙模块1和蓝牙模块2的到达角，此处，将无线信号到达蓝牙模块1的到达角记为θ1，将无线信号到达蓝牙模块2的到达角记为θ2。如图7所示，θ1、θ2是三角形的两个角，D是三角形的一个边，已知三角形的两个角和一个边，即可确定出终端相对于车机的位置，该位置可包括距离和方向。
作为再一种可行的实现方式：通过终端广播的无线信号的信号强度、以及AOA或AOD技术检测终端相对于车机的距离。例如，根据终端广播的无线信号的信号强度可计算出终端相对于车机的距离，根据AOA或AOD技术也可计算出终端相对于车机的距离，进一步，将两种方法得到的计算结果进行综合计算，得到精度较高的终端相对于车机的位置，该位置包括距离和方向。
在一些应用场景中，车机相对于车辆底盘或地面的高度较大，可以建立如图8所示的三维坐标系，如图8所示，XOY平面可以是车辆底盘所在平面或地面，此处以车辆底盘所在平面为例进行示意性说明。坐标原点O可以是车机在车辆底盘上的投影点，终端在该车辆底盘上的投影点为点80，经过坐标原点O和点80的直线与Y轴正向之间的夹角记为α1，经过车机和终端的直线与Z轴正向之间的夹角记为α2。其中，X轴正向可以是平行于车身平面且从坐标原点O指向车辆左侧的方向，即从车辆的右侧指向车辆的左侧。Y轴正向可以是平行于车身平面且从车辆前方指向车辆后侧的方向。此处，将X轴正向记为第一参考方向，将Y轴正向记为第二参考方向。Z轴正向垂直于X轴和Y轴向上。其中，α1可记为方位角(Azimuth angle)，α2可记为仰角(Elevation angle)。方位角和仰角具体可以是如上所述的终端相对于车机的角度，车机到终端之间的距离作为终端相对于车机的距离，也就是说，在如图8所示的三维坐标系中，根据终端相对于车机的角度和距离，确定驾驶员终端。
在另一些应用场景中，还可以在二维坐标系中确定驾驶员终端。例如，在图8的基础上，将车机投影在XOY平面上得到的投影点为原点O，将终端投影在XOY平面上得到的投影点为点80，将如图8所示的α1作为终端相对于车机的角度，将点80到原点O的距离作为终端相对于车机的距离，也就是说，将三维坐标系投影到二维坐标系，并在该二维坐标系下，根据终端相对于车机的角度和距离，确定驾驶员终端。
在又一些应用场景中，还可以不考虑车机和终端相对于车辆底盘或地面的高度，可以假设车机和终端在同一个高度上，或者，车机和终端的高度差小于预设高度差，此时，以车机为坐标原点O、以从坐标原点O指向车辆左侧的方向为X轴正向、以从车辆前方指向车辆后侧的方向为Y轴正向建立如图9所示的二维坐标系XOY，将经过车机和终端的直线与Y轴正向之间的夹角记为α3，该α3作为终端相对于车机的角度，终端相对于车机的距离为从坐标原点O到终端的距离，在该二维坐标系XOY中，根据终端相对于车机的角度和距离，确定驾驶员终端。
下面实施例以如图9所示的二维坐标系XOY为例，介绍根据终端相对于车机的角度和距离，确定驾驶员终端的具体过程。另外，需要说明的是，在如图9所示的二维坐标系XOY中，经过车机和终端的直线与X轴正向之间的夹角α4也可作为终端相对于车机的角度。此 外，如图9所示的二维坐标系XOY的坐标原点O还可能是车机内的某个天线的位置、或者是车机内的两个天线的中点、或者是车机内多个天线构成的平面的几何中心，此时的天线是指集成在车机内的天线。
另外，在一些应用场景中，车内可能存在多个终端，但是有些终端的软件和硬件满足如上表1所示的要求，但是，有些终端可能并不满足如上表1所示的要求。也就是说，对于满足如上表1所示要求的终端，可以实现对该终端的定位，例如，角度定位和距离定位。对于不满足如上表1所示要求的终端，则无法对该终端进行定位。例如，如图10所示的终端A、终端B、终端C、终端D、终端E均满足如上表1所示的要求，则根据终端相对于车机的距离即可确定出前排座椅上的终端和后排座椅上的终端。例如，终端A和终端B相对于车机的距离小于终端C和终端D相对于车机的距离，因此，终端A和终端B是前排座椅上的终端，终端C和终端D是后排座椅上的终端。另外，根据终端相对于车机的角度和距离，还可以确定出车内的终端和车外的终端，例如，终端A相对于车机的角度和终端E相对于车机的角度非常接近，但是，终端E相对于车机的距离大于终端A相对于车机的距离，因此，确定终端A是车内的终端，终端E是车外的终端。
例如图10所示，根据车内的终端A、终端B、终端C、终端D分别发送的无线信号，可确定出终端A、终端B、终端C、终端D分别相对于车机的角度和距离，进一步，根据终端A、终端B、终端C、终端D分别相对于车机的角度和距离可确定出哪个终端在主驾驶位置区域内，若某个终端在主驾驶位置区域内，则确定该终端为驾驶员终端。其中，确定某个终端是否在主驾驶位置区域内的方法可以是：比较该终端相对于车机的角度与主驾驶位置相对于车机的角度，若该终端相对于车机的角度与主驾驶位置相对于车机的角度匹配，且该终端相对于车机的距离小于或等于预设距离，则确定该终端在主驾驶位置区域内。如图10所示，主驾驶位置相对于车机的角度可以是X轴正方向与Y轴正方向之间第一象限的角度范围，从车机到终端A的矢量
Figure PCTCN2020115446-appb-000011
与X轴正向之间的角度在该第一象限对应的角度范围内，从车机到终端C的矢量
Figure PCTCN2020115446-appb-000012
与X轴正向之间的角度也在该第一象限对应的角度范围内。也就是说，终端A和终端C相对于车机的角度与主驾驶位置相对于车机的角度匹配，但是，终端A相对于车机的距离小于或等于预设距离，该预设距离具体可以是从车机到驾驶员座椅靠背的距离，如果驾驶员座椅相对于方向盘的距离是可调节的，则该预设距离是当驾驶员座椅调整到距离方向盘最远的位置时，从车机到驾驶员座椅靠背的距离。而终端C相对于车机的距离大于预设距离，则确定终端A在主驾驶位置区域内，因此，终端A为驾驶员终端。
在另一种可能的实现方式中，以图10为例，根据终端A、终端B、终端C、终端D分别相对于车机的角度和距离，确定终端A、终端B、终端C、终端D中的驾驶员终端时，还可以根据每个终端相对于车机的距离，以及从历史时刻到当前时刻，每个终端相对于车机的角度变化，确定驾驶员终端。其中，终端相对于车机的角度为从车机指向该终端的方向与X轴正向之间的角度。具体的，若某个终端相对于车机的距离小于或等于预设距离，且从历史时刻到当前时刻，从车机指向该终端的方向与X轴正向之间的角度从小变大，则确定该终端为驾驶员终端。此处，将X轴正向记为第一参考方向。如图10所示，终端A、终端B、终端C、终端D中的终端A和终端B相对于车机的距离小于或等于预设距离，进一步，确定终端A和终端B分别相对于车机的角度变化。例如，终端A从车辆的左前侧车门 进入到车内，可以理解从左前侧车门进入到车内的过程中，从车机指向终端A的方向与X轴正向之间的角度从小变大，假设驾驶员从左前侧车门进入到车内的时间小于或等于预设时间，终端A位于左前侧车门的时刻记为历史时刻，终端A进入车内，例如主驾驶位置的时刻记为当前时刻，则从历史时刻到当前时刻的这段时间内，从车机指向终端A的方向与X轴正向之间的角度从小变大，因此，将终端A确定为驾驶员终端。
在又一种可能的实现方式中，以图10为例，还可以将从终端A位于左前侧车门到终端A位于主驾驶位置，看成是终端A在主驾驶位置区域内，在该主驾驶位置区域内，从车机指向终端A的方向与X轴正向之间的角度从小变大，因此，将终端A确定为驾驶员终端。
此外，车内可能存在多个终端，但是，部分终端满足如上表1所示的要求，部分终端不满足如上表1所示的要求，也就是说，车机能够对车内的部分终端实现定位，对车内的部分终端不能实现定位，而能够实现定位的终端的数量、以及能够实现定位的终端在车内的分布位置可能存在多种情况，下面针对多种情况介绍驾驶员终端的确定方法。
在一种可能的情况中：车内只有一个终端，该终端可能位于前排区域或后排区域，其中，前排区域包括前排座椅区域和中控台区域。在这种情况下，车机可以将该车内唯一的一个终端确定为驾驶员终端，并与该终端进行通信连接。
在另一种可能的情况中：车内存在两个及以上可以被定位角度和距离的终端，但是能够被定位角度和距离的终端均位于后排区域，另外，车内可能还存在其他不能被定位角度和距离的终端。在这种情况下，将该车内最近一次与该车机连接过的终端作为驾驶员终端。
在又一种可能的情况中：车内存在两个及以上可以被定位角度和距离的终端，但是前排区域只存在一个能够被定位角度和距离的终端，剩余能够被定位角度和距离的终端位于后排区域，另外，车内可能还存在其他不能被定位角度和距离的终端。例如，图10所示的终端A和终端C是车内能够被定位角度和距离的终端。从车机到终端A的矢量记为

的大小，终端C相对于车机的距离为矢量
Figure PCTCN2020115446-appb-000020
的大小。若终端A相对于车机的距离小于或等于预设距离，终端C相对于车机的距离大于该预设距离，并且终端A相对于车机的第一角度在第一预设角度范围内，则确定终端A为驾驶员终端。其中，预设距离具体可以是从车机到驾驶员座椅靠背的距离，如果驾驶员座椅相对于方向盘的距离是可调节的，则该预设距离是当驾驶员座椅调整到距离方向盘最远的位置时，从车机到驾驶员座椅靠背的距离。如图11所示，X轴正向和Y轴正向构成二维坐标系XOY的第一象限，从该第一象限开始沿着逆时针方向依次为第二象限、第三象限、第四象限。该第一预设角度范围具体可以是在第一象限对应的90度范围的基础上，向第二象限扩展5度、以及向第四象限扩展5度后的角度范围，即β1所示的角度范围。或者,第一预设角度范围也可以是第一象限对应的90度范围，此处并不对第一预设角度范围做具体限定。
可以理解的是，如图11所示的β1只是第一预设角度范围的一个举例说明，在其他实施例中，第一预设角度范围还可以是其他的角度范围。例如，如图12所示的β2为第一预 设角度范围的另一种举例，具体的，0≤β2≤80度，也就是说，当终端A相对于车机的距离小于或等于如上所述的预设距离，并且从车机到终端A的方向与Y轴正向之间的角度β3大于或等于10度时，确定终端A为驾驶员终端。
另外，在图10、图11和图12中，若终端A相对于车机的角度不满足如上所述的第一预设角度范围，则将车内最近一次连接过该车机的终端作为驾驶员终端。
在又一种可能的情况中：车内存在两个及以上可以被定位角度和距离的终端，前排区域存在两个能够被定位角度和距离的终端，另外，车内可能还存在其他不能被定位角度和距离的终端。如图13所示，终端A、终端B和终端C是车内能够被定位角度和距离的终端。根据终端A、终端B和终端C分别相对于车机的距离，可确定出终端A、终端C都在前排区域，终端B在后排区域。也就是说，终端A、终端C分别相对于车机的距离均小于或等于预设距离，此处，将从车机到终端A的方向记为第一方向即矢量

与X轴正向之间的角度记为第二角度，下面根据第一角度和第二角度之间的角度关系，对确定终端A和终端C中的驾驶员终端进行介绍。
第一角度和第二角度之间的一种角度关系为：第一角度小于第二角度，并且第一方向和第二方向之间的第一夹角大于预设角度阈值，则确定终端A为驾驶员终端，终端C为副驾驶终端。该预设角度阈值具体可以是20度。具体的，矢量
Figure PCTCN2020115446-appb-000025
与X轴正向之间的第一角度小于100度，例如，驾驶员终端可能会放置在驾驶员座椅和副驾驶座椅中间的位置，在这种情况下，从车机到驾驶员终端的方向与X轴正向之间的角度可能会等于90度或稍微大于90度，在一定误差范围内，可以将驾驶员终端位于驾驶员座椅和副驾驶座椅中间位置时，从车机到驾驶员终端的方向与X轴正向之间的角度扩展到100度。另外，矢量
Figure PCTCN2020115446-appb-000026
与X轴正向之间的第二角度大于80度。例如，将矢量

第一角度和第二角度之间的另一种角度关系为：矢量

Figure PCTCN2020115446-appb-000036
与X轴正向之间的第二角度。由于驾驶员是从车的左侧上车，副驾驶从车的右侧上车，因此，驾驶员从车外到车内的过程中，从车机到驾驶员终端的方向与X轴正向之间的角度不断增大，而副驾驶从车外到车内的过程中，从车机到副驾驶终端的方向与X轴正向之间的角度不断减小。因此，若从历史时刻到当前时刻，矢量

分别与X轴正向之间的角度均在110度-180度的范围内，此处可以将0度-70度的范围记为第一预设角度范围，将110度-180 度的范围记为第二预设角度范围。在这种情况下，可以将终端A和终端C中最近一次连接过车机的终端作为驾驶员终端。可以理解的是，此处的0度-70度、110度-180度只是示意性说明，并不对第一预设角度范围和第二预设角度范围做具体限定。
在又一种可能的情况中：车内存在两个及以上可以被定位角度和距离的终端，前排区域存在两个以上能够被定位角度和距离的终端，另外，车内可能还存在其他不能被定位角度和距离的终端。如图14所示，终端A、终端B、终端C和终端D是车内能够被定位角度和距离的终端。根据终端A、终端B、终端C和终端D分别相对于车机的距离，可确定出终端A、终端B、终端C都在前排区域，终端D在后排区域。也就是说，终端A、终端B、终端C分别相对于车机的距离均小于或等于预设距离，此处，将从车机到终端A的方向记为第一方向即矢量

可以理解的是，当前排区域存在3个以上能够被定位角度和距离的终端时，从该3个以上终端中确定驾驶员终端的方法类似于如上所述的从终端A、终端B和终端C中确定驾驶员终端的方法，此处不再赘述。
本实施例通过确定车辆内能够实现定位的终端的数量、以及能够实现定位的终端在车内的分布位置可能存在的多种情况，针对每种情况介绍了驾驶员终端的确定方法，从而提高了确定驾驶员终端的精确度和灵活性。
在上述实施例的基础上，车辆内的终端的数量和位置可能会发生变化，当车机检测到新的驾驶员终端时，可以断开当前的连接，而与最新确定的驾驶员终端进行通信连接。但是，如果当前时刻车辆处于行驶状态，则车机可以不再检测最新的驾驶员终端，或者，即使检测到了最新的驾驶员终端，也不断开当前的连接，从而避免车机连接的终端不断变化，同时也为了行驶安全。另外，如果车内的某个终端确实有连接车机的需求，该终端的用户可手动连接到该车机，在这种情况下，车机可以不再检测最新的驾驶员终端，或者，即使检测到了最新的驾驶员终端，也不断开当前的连接。
