Description

一种位置的获取方法以及相关设备
本申请要求于2021年10月30日提交中国专利局、申请号为202111278602.X、发明名称为“一种位置的获取方法以及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及计算机技术领域，尤其涉及一种位置的获取方法以及相关设备。
背景技术
随着汽车功能的不断升级，带给用户的体验也愈发的丰富多彩，而这些功能往往都是无差异性的提供给用户，无论用户相对于车辆的位置是哪里，车辆所提供给用户的功能是一模一样的。然而，位于不同位置的用户对车辆功能的需求可能会有差异，不过实现这一功能的前提是先要确定用户当前的位置。
因此，一种用于测量用户相对于车辆的位置的方案亟待推出。
发明内容
本申请提供了一种位置的获取方法以及相关设备，根据第一时间集合和第二时间集合之间的时间间隔来确定终端设备位于车辆内部还是车辆外部，从而提供了一种测量用户相对于车辆的位置的方案；此外，音频信号可以通过车辆中自带的音响发出，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
为解决上述技术问题，本申请提供以下技术方案：
第一方面，本申请提供一种位置的获取方法，可用于智能车辆领域中。方法应用于位置的获取系统，位置的获取系统包括车辆和终端设备，方法包括：在车辆检测到满足第一触发条件的情况下，发送至少一个目标音频信号，其中，目标音频信号用于确定与目标音频信号对应的至少一个到达时间。进一步地，车辆发送至少一个目标音频信号，包括：按照第一预设频率发送多个目标音频信号；其中，多个目标音频信号包括第一探测信号和第二探测信号，至少一个到达时间包括第一探测信号所对应的第一时间集合和第二探测信号所对应的第二时间集合，第一时间集合包括第一探测信号通过直射和/或反射到达终端设备的至少一个时间，第二时间集合包括第二探测信号通过直射和/或反射到达终端设备的至少一个时间；进一步地，车辆发送第一探测信号的时间可以早于车辆发送第二探测信号的时间，或者，车辆发送第一探测信号的时间可以晚于车辆发送第二探测信号的时间；第一探测信号和第二探测信号为两个不同的目标音频信号，且相邻到达终端设备。车辆获取与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部，第一时间集合和第二时间集合中的到达时间之间的时间间隔用于确定第一位置信息。
本实现方式中，车辆发送多个目标音频信号，由于车辆内部的空间比较封闭，则一个目标音频信号经过直射和/或反射后得到的多个音频信号能够较为集中的到达终端设备，而车辆外部的空间相对于车辆内部的空间较为开阔，一个目标音频信号经过直射和/或反射后 得到的多个音频信号会比较分散的到达终端设备，因此能够根据第一时间集合和第二时间集合之间的时间间隔来确定终端设备位于车辆内部还是车辆外部，从而提供了一种测量用户相对于车辆的位置的方案；此外，音频信号可以通过车辆中自带的音响发出，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
在第一方面的一种可能实现方式中，目标音频信号为线性调频信号或ZC序列信号。进一步地，目标音频信号所在频段可以为17KHZ-48KHZ，可选地，目标音频信号所在频段可以为17KHZ-22KHZ。
本实现方式中，由于线性调频信号或者ZC序列信号为能量聚集型信号，选用线性调频信号或者ZC序列信号作为目标音频信号，有利于准确的估计每个目标音频信号所对应的至少一个到达时间，从而有利于得到准确的第一位置信息。
在第一方面的一种可能实现方式中，若第一时间集合和第二时间集合中的到达时间之间的时间间隔位于预设时间范围内，则第一位置信息指示终端设备位于车辆内部；若第一时间集合和第二时间集合中的到达时间之间的时间间隔不位于预设时间范围内，则第一位置信息指示终端设备位于车辆外部。其中，预设时间范围的确定因素包括车辆发送两个相邻的目标音频信号之间的时间间隔，预设时间范围所采用的时间度量单位可以包括采样点、毫秒、秒或其他时间度量单位等等，作为示例，例如预设时间范围可以为d-c个采样点至d+e个采样点，d个采样点为车辆发送两个目标音频信号之间的时间间隔。
本实现方式中，预设时间范围可以基于车辆发送两个相邻的目标音频信号之间的时间间隔确定，从而提供了一种简单的预设时间范围的确定方式。
在第一方面的一种可能实现方式中，第一时间集合和第二时间集合中的到达时间之间的时间间隔包括：第一时间集合中最晚的时间和第二时间集合中最早的时间之间的时间间隔。本实现方式中，提供了利用第一时间集合和第二时间集合中的到达时间之间的时间间隔，得到终端设备的第一位置信息的一种具体实现方式，操作简单，易于实现。
在第一方面的一种可能实现方式中，当车辆检测到如下任一种或多种情况时，视为检测到满足第一触发条件：检测到车辆停车；或者，检测到终端设备与车辆之间的距离满足第一距离条件；或者，获取到第一指令，第一指令用于触发车辆获取第一位置信息。
本实现方式中，提供了第一触发条件的多种具体表现形式，扩展了本方案的应用场景，提高了本方案的实现灵活性。
在第一方面的一种可能实现方式中，车辆检测到车辆停车，可以包括：车辆获取车辆的速度、加速度和角速度，并将车辆的速度、加速度和角速度输入分类模型，得到分类模型输出的预测类别信息。其中，该分类模型为已经执行过训练操作的模型，分类模型可以具体表现为神经网络，也可以表现为非神经网络的模型。作为示例，例如该分类模型可以具体表现为决策树、随机森林、极度随机树、支持向量机、K-临近(KNN)模型、逻辑回归模型或其他类型的分类模型等，此处不做穷举。预测类别信息指示车辆处于停止状态或移动状态，在一种实现方式中，分类模型输出的预测类别信息可以包括第一概率值和第二概率值，第一概率值用于指示车辆为停止状态的概率，第二概率值用于指示车辆为移动状态的概率；在另一种实现方式中，分类模型输出的预测类别信息可以为第一值或第二值，当 分类模型输出的预测类别信息为第一值时，代表车辆处于停止状态，当分类模型输出的预测类别信息为第二值时，代表车辆处于移动状态。
本实现方式中，将车辆的速度、加速度和角速度输入分类模型中，以通过该分类模型确定车辆处于停止状态还是移动状态，避免了从车辆的控制系统中获取车辆的状态，保证了车辆的控制系统在终端设备的目标位置信息的测量过程中的独立性，有利于提高车辆运行过程的安全性。
第二方面，本申请提供一种位置的获取方法，可用于智能车辆领域中。方法应用于位置的获取系统，位置的获取系统包括车辆和终端设备，方法包括：在终端设备检测到满足第二触发条件的情况下，获取与至少一个目标音频信号对应的至少一个到达时间，至少一个目标音频信号包括由车辆按照预设频率发出的多个目标音频信号，多个目标音频信号包括第一探测信号和第二探测信号，至少一个到达时间包括第一探测信号所对应的第一时间集合和第二探测信号所对应的第二时间集合，第一时间集合包括第一探测信号通过直射和/或反射到达终端设备的至少一个时间，第二时间集合包括第二探测信号通过直射和/或反射到达终端设备的至少一个时间。终端设备根据第一时间集合和第二时间集合中的到达时间之间的时间间隔，生成与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部。
在第二方面的一种可能实现方式中，若第一时间集合和第二时间集合中的到达时间之间的时间间隔位于预设时间范围内，则第一位置信息指示终端设备位于车辆内部，其中，预设时间范围的确定因素包括车辆发送两个相邻的目标音频信号之间的时间间隔；若第一时间集合和第二时间集合中的到达时间之间的时间间隔不位于预设时间范围内，则第一位置信息指示终端设备位于车辆外部。
在第二方面的一种可能实现方式中，终端设备根据第一时间集合和第二时间集合中的到达时间之间的时间间隔，生成与终端设备对应的第一位置信息，包括：终端设备根据第一时间集合中最晚的时间和第二时间集合中最早的时间之间的时间间隔，生成第一位置信息。
在第二方面的一种可能实现方式中，当终端设备检测到如下任一种或多种情况时，视为检测到满足第二触发条件：检测到车辆停车；或者，检测到终端设备与车辆之间的距离满足第一距离条件；或者，检测到终端设备的位移符合预设位移；或者，获取到第二指令，第二指令用于触发终端设备获取第一位置信息。
对于本申请第二方面以及第二方面的各种可能实现方式中的具体实现步骤、名词的具体含义以及每种可能实现方式所带来的有益效果，均可以参考第一方面中各种可能的实现方式中的描述，此处不再一一赘述。
第三方面，本申请提供一种位置的获取方法，可用于智能车辆领域中。方法应用于位置的获取系统，位置的获取系统包括车辆和终端设备，方法包括：车辆按照第二预设频率发送多个目标音频信号；其中，在车辆处于移动状态的情况下，一个目标音频信号用于确定目标音频信号到达终端设备的一个第一到达时间，在满足第二触发条件的情况下，一个目标音频信号用于确定目标音频信号到达终端设备的一个第二到达时间。进一步地，第一 到达时间可以为与每个目标音频信号对应的至少一个到达时间可以仅包括一个到达时间；或者，前述第一到达时间可以为与每个目标音频信号对应的至少一个到达时间中最早的一个到达时间；或者，前述第一到达时间可以为与每个目标音频信号对应的至少一个到达时间中最晚的一个到达时间；或者，第一到达时间也可以选用与每个目标音频信号对应的至少一个到达时间中的其它到达时间；第二到达时间与第一到达时间的含义类似，区别在于，第一到达时间是在车辆处于移动状态下获得的，第二到达时间是在终端设备检测到满足第二触发条件后获得的。车辆获取与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部，多个第一到达时间和至少一个第二到达时间用于确定第一位置信息。
本申请实施例中，从而提供了一种测量终端设备是位于车辆内部还是位于车辆外部的另一种方案，提高了本方案的实现灵活性；且也即利用音频信号来测量终端设备是位于车辆内部还是位于车辆外部，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
在第三方面的一种可能实现方式中，多个第一到达时间用于确定与第二到达时间对应的第一预测时间，第一预测时间指示在终端设备位于车辆内部的情况下，目标音频信号到达终端设备的时间，第一预测时间和第二到达时间用于确定第一位置信息。
本申请实施例中，由于当车辆处于移动状态时，能够持续收到音频信号的终端设备一定是位于车内的，从而可以根据获取到的多个第一到达时间来得到第一预测时间，进而根据生成的第一预测时间和实际的第二到达时间，来确定终端设备是位于车辆内部还是外部，仅需一个音响就能实现终端设备的第一位置信息的检测，进一步降低了本方案的实现难度，有利于扩展本方案的应用场景。
对于本申请第三方面以及第三方面的各种可能实现方式中名词的具体含义，均可以参考第一方面中各种可能的实现方式中的描述，此处不再一一赘述。
第四方面，本申请提供一种位置的获取方法，可用于智能车辆领域中。方法应用于位置的获取系统，位置的获取系统包括车辆和终端设备，方法包括：在车辆处于移动状态的情况下，终端设备获取与多个目标音频信号对应的多个第一到达时间，一个第一到达时间代表一个目标音频信号到达终端设备的时间，多个目标音频信号为车辆按照预设频率发出的；在检测到满足第二触发条件的情况下，终端设备获取与至少一个目标音频信号对应的至少一个第二到达时间，根据多个第一到达时间和至少一个第二到达时间，生成与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部。
在第四方面的一种可能实现方式中，终端设备根据多个第一到达时间和至少一个第二到达时间，生成与终端设备对应的第一位置信息，包括：终端设备根据多个第一到达时间确定与第二到达时间对应的第一预测时间，第一预测时间指示在终端设备位于车辆内部的情况下，目标音频信号到达终端设备的时间；终端设备根据第一预测时间和第二到达时间，生成第一位置信息。
对于本申请第四方面以及第四方面的各种可能实现方式中的具体实现步骤、名词的具体含义以及每种可能实现方式所带来的有益效果，均可以参考第三方面中各种可能的实现方式中的描述，此处不再一一赘述。
第五方面，本申请提供一种位置的获取方法，可用于智能车辆领域中。方法应用于位置的获取系统，位置的获取系统包括车辆和终端设备，车辆配置有至少三个音响，至少三个音响不位于一条直线上，至少三个音响包括第一音响、第二音响和第三音响，方法包括：车辆通过第一音响发送第一音频信号，第一音频信号用于确定终端设备接收到的第一音频信号的第一信号强度；车辆通过第二音响发送第二音频信号，第二音频信号用于确定终端设备接收到的第二音频信号的第二信号强度；车辆通过第三音响发送第三音频信号，第三音频信号用于确定终端设备接收到的第三音频信号的第三信号强度，第一信号强度、第二信号强度和第三信号强度用于确定与终端设备对应的第二位置信息，第二位置信息用于指示终端设备位于车辆外部的位置。
本申请实施例中，由于当终端设备位于车辆外部的不同位置上时，终端设备与各个音响之间的距离关系不同，音频信号传播越远，终端设备接收到的音频信号的强度越小，则第一信号强度、第二信号强度和第三信号强度能够分别反应终端设备与第一音响、第二音响以及第三音响之间的距离关系，因此能够基于第一信号强度、第二信号强度和第三信号强度得到终端设备位于车辆外部的具体位置，提供了测量终端设备在车辆外部的具体位置的又一实现方式，提高了本方案的实现灵活性。
在第五方面的一种可能实现方式中，第二位置信息用于供车辆从车辆包括的多个组件中确定与终端设备之间距离最近的组件，以控制与终端设备之间距离最近的组件执行预设操作。其中，组件可以为车门、车灯、后备箱或其他车辆组件，预设操作可以为解锁车门、打开车门、解锁后备箱、打开车灯或其他操作等。

具体的，请参阅图3，图3为本申请实施例提供的位置的获取方法的一种流程示意图，本申请实施例提供的位置的获取方法可以包括：
301、车辆和终端设备启动车内位置感知操作。
本申请实施例中，在一些应用场景中，在车辆的运行过程中，当车辆确定需要获知终端设备在车辆内部的位置时，会启动车内位置感知操作，并向终端设备发送第一指示信息，第一指示信息用于指示终端设备启动车内位置感知操作。需要说明的是，实施例一中由车辆执行的步骤具体可以为由车辆中的处理器执行，也可以为由车辆中的车辆辅助设备执行，具体结合实际产品形态决定，后续不再进行说明。
作为示例，例如车辆需要为车内的至少一个终端设备分别分配对车辆的控制权限，但位于车内不同位置上的终端设备所对应的控制权限不同，则需要获取车内的每个终端设备在车内的位置，则车辆可以触发启动车内位置感知操作。
作为另一示例，例如车辆需要与位于副驾驶位上的终端设备连接，并将位于副驾驶位置上的终端设备的屏幕投影至中控屏上，则车辆需要获取车内的每个终端设备在车内的位置，以从至少一个终端设备中确定位于副驾驶位置上的终端设备，则车辆可以触发启动车内位置感知操作等，需要说明的是，车辆还可以在其他场景下触发启动车内位置感知操作，此处举例仅为方便理解本方案，不用于限定本方案。
在另一些应用场景中，在终端设备的运行过程中，当终端设备确定需要获知终端设备在车辆内部的位置时，会启动车内位置感知操作，并向车辆发送第二指示信息，第二指示 信息用于指示车辆启动车内位置感知操作。
作为示例，例如当位于车内的某一终端设备想要开启投屏操作时，由于车辆上可以配置有多个显示屏，则该终端设备可以启动车内位置感知操作，以从车内的多个显示屏中获取与该终端设备距离最近的一个显示屏和该终端设备自动连接；或者，终端设备上可以展示显示屏列表，显示屏列表中展示有所有可以连接的显示屏，与该终端设备距离最近的一个显示屏被置顶。
作为另一示例，例如终端设备是无线耳机，该无线耳机想要与车内最近的屏幕连接，以通过该无线耳机播放前述屏幕输出的声音，则该无线耳机可以启动车内位置感知操作，以从车内的多个显示屏中获取与该无线耳机距离最近的一个显示屏等，应理解，终端设备还可以在其他场景下触发启动车内位置感知操作，此处不做一一进行列举。
具体的，在一些应用场景中，车辆可以通过广播的方式向车内的终端设备发送第一指示信息，终端设备在接收到第一指示信息之后，触发终端设备开启车内位置感知操作，终端设备向车辆发送第一反馈消息，从而完成了车辆和某个确定的终端设备之间的通信连接，该第一反馈消息用于告知车辆该终端设备已成功开启车内位置感知操作。
上述广播的方式可以为通过蓝牙信号进行广播、通过无线宽带(wireless fidelity，WIFI)热点的形式进行广播或其他方式进行广播等，此处不做穷举。
车辆在确定终端设备已经开启车内位置感知操作之后，可以向车辆内的至少一个终端设备发送第三指示信息，第三指示信息用于指示终端设备开始准备接收超声信号，之后开始通过至少两个音响分别发送超声信号。但需要说明的是，若车辆内部同时存在多个终端设备，由于本方案中是由终端设备生成每个终端设备所对应的目标位置信息，则车辆可以同时向车内的多个终端设备发送第三指示信息，也可以逐个获取终端设备在车内的位置。
在另一些应用场景中，车内的终端设备可以通过广播的方式向车辆发送第二指示信息，车辆在接收到第二指示信息之后，触发车辆开启车内位置感知操作，终端设备向车辆发送第二反馈消息，该第二反馈消息用于告知终端设备该车辆已成功开启车内位置感知操作，从而终端设备可以准备开始接收超声信号。
进一步地，若车辆接收到车内的多个终端设备发送的第二指示信息，则车辆可以同时向车辆内的多个终端设备发送第二反馈消息，以使多个终端设备同时开始测量自身在车辆内部的位置；车辆也可以向车辆内的多个终端设备逐个发送第二反馈消息，以使多个终端设备开始逐个测量自身在车辆内部的位置。
本实现方式中，提供了触发车辆开始发送超声信号，以及终端设备开始接收超声信号的具体实现方式，提高了本方案的完整性；且无论是车辆想要获取终端设备的目标位置信息，还是终端设备想要获取终端设备的目标位置信息，都能够触发超声信号的发送和接收操作，扩展了本方案的应用场景。
302、车辆通过第一音响向终端设备发送第一超声信号。
本申请实施例中，车辆中配置有至少两个音响，该至少两个音响包括第一音响和第二音响，第一音响和第二音响配置于车辆的不同的两侧。进一步地，若第一音响和第二音响分别配置于车辆的前侧和后侧，则一个目标位置信息可以用于指示一个终端设备在车辆内 部的前排位置还是在车辆内部的后排位置；或者，若第一音响和第二音响可以分别配置于车辆的左侧和右侧，则一个目标位置信息可以用于指示一个终端设备在车辆内部的左侧位置还是在车辆内部的右侧位置。
可选地，车辆内部配置的至少两个音响可以包括至少三个音响，至少三个音响可以包括第一音响、第二音响和第三音响，该至少三个音响不位于一条直线上，则一个目标位置信息可以用于指示一个终端设备在车辆的内部的一个确定的位置。作为示例，例如车辆中有5个车内位置，该5个位置分别为主驾驶位置、副驾驶位置、后排左侧位置、后排中间位置和后排右侧位置，则一个目标位置信息可以用于指示前述5个车内位置中的一个明确的车内位置，应理解，前述举例仅为方便理解本方案，不用于限定本方案。
为更直观地理解本方案，请参阅图4，图4为本申请实施例提供的位置的获取方法中至少三个音响的一种位置示意图，图4中以车辆通过三个音响发送超声信号，且车辆为小轿车为例，图4包括(a)、(b)和(c)三个子示意图，如图4的(a)子示意图所示，该三个音响可以分别位于车辆内部的左前方位置、右前方位置和左后方位置；如图4的(b)子示意图所示，该三个音响可以分别位于车辆内部的左前方位置、右前方位置和后排中间；如图4的(c)子示意图所示，该三个音响可以分别位于车辆内部的左前方位置、右前方位置和右后方位置等，应理解，图4中的示例仅为方便理解音响的位置，车辆也可以通过其他位置的音响来发出超声信号等，此处不做穷举。如图4和图5所示，本申请实施例根据车辆的俯视图来描述各个音响的位置，如左前方位置、右前方位置、左后方位置和右后方位置。
本申请实施例中，利用车辆内部的至少三个音响来确定终端设备在车辆内部的位置，且至少三个音响不在同一条直线上，能够得到终端设备在车辆内部的精确位置，有利于后续为终端设备提供更为精细化的管理。
进一步可选地，车辆内部配置的至少三个音响包括四个音响，该四个音响包括第一音响、第二音响、第三音响和第四音响，该四个音响分别位于所述车辆的左前方位置、右前方位置、左后方位置和右后方位置。本申请实施例中，一般车辆自带的音响就分别位于左前方位置、右前方位置、左后方位置和右后方位置，不仅不需要在车辆上增加额外的元器件，且由于所采用的音响数量越多，得到的目标位置信息的错误率越低，充分利用车辆中已有的四个音响后，有利于提高得到的目标位置信息的准确度。
本申请实施例中，车辆可以通过第一音响采用广播的方式向终端设备发送第一超声信号，对应的，车辆内部的一个确定的终端设备(为方便描述，后续称为“目标终端设备”)接收第一音响发送的第一超声信号，目标终端设备还会获取第一超声信号的接收时间。
其中，第一超声信号所在频段可以为17KHZ-48KHZ，可选地，第一超声信号所在频段可以为17KHZ-23KHZ，作为示例，例如第一超声信号的频率可以为23KHZ左右，具体第一超声信号的频率为多少可以结合实际应用产品确定，此处不做限定。
303、车辆通过第二音响向终端设备发送第二超声信号。
本申请实施例中，车辆可以通过第二音响采用广播的方式向终端设备发送第二超声信号，对应的，目标终端设备接收第二音响发送的第二超声信号，目标终端设备还会获取第 二超声信号的接收时间，第二音响和第一音响为两个不同的音响。
具体的，在一种实现方式中，若同时执行步骤302和步骤303，则第一超声信号和第二超声信号为不同的超声信号，两个不同的超声信号可以为如下任一种或多种不同：频率不同、信号调制方式不同、波形不同、副值不同或其他类型的不同等。
在另一种实现方式中，若先执行步骤302，在预设时间间隔后再执行步骤303，则第一超声信号和第二超声信号可以为相同的超声信号，也可以为不同的超声信号，作为示例，例如预设时间间隔可以为0.05秒、0.1秒、0.15秒、0.2秒或其他时长等，具体取值可以结合实际应用产品确定，此处不做限定。
304、车辆通过第三音响向终端设备发送第三超声信号。
本申请的一些实施例中，若车辆利用至少三个音响来获取终端设备在车内的具体位置，则车辆还可以通过第三音响采用广播的方式向终端设备发送第三超声信号，对应的，目标终端设备接收第三音响发送的第三超声信号，目标终端设备还会获取第三超声信号的接收时间，第三音响、第二音响和第一音响均为不同的音响。
具体的，在一种实现方式中，若同时执行步骤302、步骤303和步骤304，则第一超声信号、第二超声信号和第三超声信号均为不同的超声信号。
在另一种实现方式中，若先执行部步骤302，在预设时间间隔后再执行步骤303，在预设时间间隔后再执行步骤304，则第一超声信号、第二超声信号和第三超声信号可以为相同的超声信号，也可以为不同的超声信号。
可选地，若车辆利用四个音响来获取终端设备在车内的具体位置，则车辆还可以通过第四音响采用广播的方式向终端设备发送第四超声信号，对应的，目标终端设备接收第四音响发送的第四超声信号，目标终端设备还会获取第四超声信号的接收时间，第四音响、第二音响和第一音响均为不同的音响。
具体的，在一种实现方式中，若车辆同时通过第一音响、第二音响、第三音响和第四音响向终端设备发送超声信号，则第一超声信号、第二超声信号、第三超声信号和第四超声信号均为不同的超声信号。
在另一种实现方式中，若逐个通过第一音响、第二音响、第三音响和第四音响向终端设备发送超声信号，两个相邻的超声信号的发送时间之间的时间间隔是预设时间间隔，则第一超声信号、第二超声信号、第三超声信号和第四超声信号可以为相同的超声信号，也可以为不同的超声信号。
305、终端设备根据第一超声信号的接收时间和第二超声信号的接收时间，确定目标位置信息，目标位置信息用于指示终端设备位于车辆内部的位置。
本申请实施例中，终端设备可以根据第一超声信号的接收时间和第二超声信号的接收时间，确定目标位置信息，目标位置信息用于指示终端设备位于车辆内部的位置。
进一步地，由于第一超声信号的接收时间和第二超声信号的接收时间能够反映出终端设备与第一音响和第二音响之间的距离的大小关系，而车辆中的多个音响的位置是固定的，当终端设备相对于车辆的位置不同时，终端设备与各个音响之间的距离关系也会不同，因此能够确定终端设备的目标位置信息。
可选地，若车辆通过至少三个音响发送超声信号，则终端设备可以根据第一超声信号的接收时间、第二超声信号的接收时间和第三超声信号的接收时间，确定目标位置信息。
进一步可选地，若车辆通过四个音响发送超声信号，则终端设备可以根据第一超声信号的接收时间、第二超声信号的接收时间、第三超声信号的接收时间和第四超声信号的接收时间，确定目标位置信息。
具体的，在一种实现方式中，车辆同时通过至少两个音响发送超声信号，也即同时执行步骤302、步骤303和步骤304，则步骤305可以包括：目标终端设备上可以配置有不同类型的超声信号和不同位置上的音响之间的一一对应关系，也即每个位置上的音响可以固定的发一种类型的超声信号，从而终端设备可以预先得知哪种类型的超声信号是由哪个位置上的音响发出的。目标终端设备根据至少两个超声信号中不同的超声信号的接收时间，确定不同的超声信号到达终端设备的先后顺序。
由于车辆是同时通过多个音响发送超声信号的，则某个位置的音响发送的超声信号到达目标终端设备的时间越晚，证明该音响与目标终端设备之间的距离越长，也即各个超声信号到达终端设备的先后顺序就代表了目标终端设备与每个位置上的音响之间的距离的大小。车辆中的多个音响的位置是固定的，不同的车内位置与各个音响之间的距离关系不同，因此终端设备可以根据不同的超声信号到达终端设备的先后顺序，确定目标终端设备在车辆内部的位置(也即确定目标终端设备的目标位置信息)。
更具体的，在一种情况中，若车辆通过分别位于左前方位置、右前方位置、左后方位置和右后方位置的四个音响向终端设备发送超声信号，则目标终端设备可以分别获取到第一超声信号的接收时间、第二超声信号的接收时间、第三超声信号的接收时间和第四超声信号的接收时间，确定第一超声信号、第二超声信号、第三超声信号和第四超声信号到达目标终端设备的先后顺序，确定目标终端设备的目标位置信息；其中，车辆内部存在N个位置，目标位置信息用于指示目标终端设备位于该N个位置中的目标位置上，N为大于1的整数。
进一步地，此处以车辆内部包括主驾驶、副驾驶、后排左侧、后排右侧和后排中间这5个车内位置为例，对基于各个超声信号到达目标终端设备的先后顺序，确定目标终端设备的目标位置信息的原理进行展示。若位于左前方位置的音响发出的超声信号先到达目标终端设备，位于右前方位置和左后方位置的音响发出的超声信号次之，位于右后方位置的音响发出的超声信号最晚到达目标终端设备，则确定目标终端设备位于车内的主驾驶位置上。
若位于右前方位置的音响发出的超声信号先到达目标终端设备，位于左前方位置和右后方位置的音响发出的超声信号次之，位于左后方位置的音响发出的超声信号最晚到达目标终端设备，则确定目标终端设备位于车内的副驾驶位置上。
若位于左后方位置的音响发出的超声信号先到达目标终端设备，位于左前方位置和右后方位置的音响发出的超声信号次之，位于右前方位置的音响发出的超声信号最晚到达目标终端设备，则确定目标终端设备位于车内的后排左侧位置上。
若位于右后方位置的音响发出的超声信号先到达目标终端设备，位于右前方位置和左 后方位置的音响发出的超声信号次之，位于左前方位置的音响发出的超声信号最晚到达目标终端设备，则确定目标终端设备位于车内的后排右侧位置上。
若位于左前方位置和右前方位置的音响发出的超声信号基本同时到达目标终端设备，位于左后方位置和右后方位置的音响发出的超声信号基本同时到达目标终端设备，且位于左后方位置和右后方位置的音响发出的超声信号早于位于左前方位置和右前方位置的音响发出的超声信号到达目标终端设备，则确定目标终端设备位于车内的后排中间位置。
为了对本申请实施例有更直观地理解，请参阅图5，图5为本申请实施例提供的位置的获取方法的一种原理示意图。如图5所示，音响1与终端设备1之间的距离最近，音响2和音响3与终端设备1之间的距离次之，音响4与终端设备1之间的距离最远；则若终端设备1发现音响1发出的超声信号先到达，音响2和音响3发出的超声信号次之，音响4发出的超声信号最后到达，则终端设备1可以确定自己位于主驾驶位置上。
音响1和音响2与终端设备2之间的距离相似，音响3和音响4与终端设备2之间的距离相似，且音响1和音响2与终端设备2之间的距离大于音响3和音响4与终端设备2之间的距离，则若终端设备2发现音响3和音响4发出的超声信号基本同时到达，音响1和音响2发出的超声信号基本同时到达，且音响3和音响4发出的超声信号早于音响1和音响2发出的超声信号到达，则终端设备2可以确定自己位于后排中间位置上，应理解，图5中的示例仅为更直观地理解本方案，不用于限定本方案。
在另一种情况中，车辆可以通过两个音响来确定终端设备位于车辆内部的左侧位置或者右侧位置。设置两个音响分别位于车辆的左侧和右侧，使得左侧的音响与左侧位置的距离小于左侧的音响与右侧位置的距离，并且使得右侧的音响与右侧位置的距离小于右侧的音响与左侧位置的距离。车辆通过这两个音响向终端设备发送超声信号，能够通过目标终端设备接收到的超声信号确定目标终端设备位于车辆内部的左侧位置或右侧位置。
进一步地，若位于车辆左侧的音响发出的超声信号先到达目标终端设备，位于车辆右侧的音响发出的超声信号后到达目标终端设备，则目标终端设备位于车辆的左侧位置。若位于车辆右侧的音响发出的超声信号先到达目标终端设备，位于车辆左侧的音响发出的超声信号后到达目标终端设备，则目标终端设备位于车辆的右侧位置。
在另一种情况中，车辆可以通过两个音响来确定终端设备位于车辆内部的前排位置(主驾驶位置和副驾驶位置)或者后排位置(后排座位)。设置两个音响分别位于车辆的前侧和后侧，使得前侧的音响与前排位置的距离小于前侧的音响与后排位置的距离，并且使得后侧的音响与后排位置的距离小于后侧的音响与前排位置的距离。根据目标终端设备接收到的超声信号能够确定目标终端设备位于车辆内部的前排位置或后排位置。
进一步地，若位于车辆前侧的音响发出的超声信号先到达目标终端设备，位于车辆后侧的音响发出的超声信号后到达目标终端设备，则目标终端设备位于车辆的前排位置。若位于车辆后侧的音响发出的超声信号先到达目标终端设备，位于车辆前侧的音响发出的超声信号后到达目标终端设备，则目标终端设备位于车辆的后排位置。
需要说明的是，本申请实施例中不再对当车内通过其他数量的音响或音响位于其他位置上时，以确定终端设备的车内位置的具体实现方案一一进行详细描述，可以基于同一个 原理进行推理理解，前述原理为在发送超声信号的位置固定之后，不同的车内位置上的终端设备与不同位置上的音响的距离的远近关系不同，且由于不同的超声信号到达目标终端设备的先后顺序能够代表不同位置上的音响与终端设备之间的距离的远近关系，则目标终端设备可以根据不同的超声信号到达目标终端设备的先后顺序来确定目标终端设备的车内位置。
本申请实施例，由于终端设备与某个音响之间的距离越远，则该音响发出的超声信号到达终端设备的时间越晚，若车辆同时通过不同位置上的音响向终端设备发送不同的超声信号，不同的超声信号到达终端设备的先后顺序可以很好的反应终端设备与各个音响之间的距离关系，进而可以很直观地推导出终端设备在车辆内部的具体位置，提供了一种简单的目标位置信息的获取方案，易于实现。
在另一种实现方式中，车辆逐个通过至少两个音响中不同的音响向终端设备发送超声信号，两个相邻的超声信号的发送时间之间的时间间隔是预设时间间隔，车辆通过不同音响发出的超声信号可以相同，也可以不同。则步骤305可以包括：目标终端设备根据第一超声信号的接收时间、第二超声信号的接收时间和预设时间间隔，确定目标终端设备在车辆内部的位置(也即确定目标终端设备的目标位置信息)。
由于车辆是按照预设时间间隔，逐个通过不同的音响发送超声信号的，则目标终端设备可以根据每个超声信号的实际接收顺序，确定接收到的每个超声信号是来源于哪个位置上的音响，并且可以根据每个超声信号的实际接收时间和预设时间间隔，得知目标终端设备与每个位置上的音响之间的距离大小的实际排序，进而可以确定目标终端设备在车辆内部的位置，该原理可参阅上一实现方式中的描述。
更具体的，在一种情况中，若车辆通过分别位于左前方位置、右前方位置、左后方位置和右后方位置的四个音响向终端设备发送超声信号，则目标终端设备可以分别获取到第一个到达的超声信号(也即由第一音响发送的第一超声信号)的第一接收时间、第二个到达的超声信号(也即由第二音响发送的第二超声信号)的接收时间、第三个到达的超声信号(也即由第三音响发送的第三超声信号)的接收时间和第四个到达的超声信号(也即由第四音响发送的第四超声信号)的接收时间；将第二个到达的超声信号的接收时间减去预设时间间隔，得到与第二个到达的超声信号对应的第二接收时间；将第三个到达的超声信号的接收时间减去2*预设时间间隔，得到与第三个到达的超声信号对应的第三接收时间；将第四个到达的超声信号的接收时间减去3*预设时间间隔，得到与第四个到达的超声信号对应的第四接收时间。
目标终端设备根据第一接收时间、第二接收时间、第三接收时间和第四接收时间，确定目标终端设备的目标位置信息。进一步地，由于车辆在发出第一超声信号，预设时间间隔后会发出第二超声信号，再在预设时间间隔后会发出第三超声信号，再在预设时间间隔后会发出第四超声信号，因此，第一接收时间、第二接收时间、第三接收时间和第四接收时间就能够代表各个音响与目标终端设备之间的距离。其中，第一接收时间越早，则代表第一音响与目标终端设备之间的距离越近，第一接收时间越晚，则代表第一音响与目标终端设备之间的距离越远，第二接收时间、第三接收时间和第四接收时间所代表的含义和第 一接收时间所代表的含义相同。在至少两个音响的位置固定以后，不同的车内位置与各个音响之间的距离关系不同，因此目标终端设备可以根据第一接收时间、第二接收时间、第三接收时间和第四接收时间，确定目标终端设备的目标位置信息。
在另一种情况中，若车辆通过两个音响向终端设备发送超声信号。则目标终端设备可以分别获取到第一个到达的超声信号(也即由第一音响发送的第一超声信号)的第一接收时间、第二个到达的超声信号(也即由第二音响发送的第二超声信号)的接收时间，将第二个到达的超声信号的接收时间减去预设时间间隔，得到与第二个到达的超声信号对应的第二接收时间。若第一接收时间早于第二接收时间，则确定目标终端设备位于第一音响所在的一侧；若第一接收时间晚于第二接收时间，则确定目标终端设备位于第二音响所在的一侧。
其中，若第一音响和第二音响分别被设置于车辆的左侧和右侧，使得第一音响和第二音响中位于左侧的音响与左侧位置的距离小于左侧的音响与右侧位置的距离，并且使得第一音响和第二音响中位于右侧的音响与右侧位置的距离小于右侧的音响与左侧位置的距离。目标终端设备的目标位置信息用于指示目标终端设备位于车辆内部的左侧位置或右侧位置。
若第一音响和第二音响分别被设置于车辆的前侧和后侧，使得第一音响和第二音响中位于前侧的音响与前排位置的距离小于前侧的音响与后排位置的距离，并且使得第一音响和第二音响中位于后侧的音响与后排位置的距离小于后侧的音响与前排位置的距离。目标终端设备的目标位置信息用于指示目标终端设备位于车辆内部的前排位置或后排位置。
需要说明的是，本申请实施例中不再对当车内通过其他数量的音响或音响位于其他位置上时，以确定终端设备的车内位置的具体实现方案一一进行赘述，可参阅上述描述理解。
本申请实施例，提供了另一种目标位置信息的获取方案，提高了本方案的实现灵活性，且依次通过不同的音响向终端设备发送超声信号，降低了终端设备对各个超声信号进行处理的过程的难度，有利于提高最终获取到的目标位置信息的准确度。
本申请实施例中，提供了一种测量用户相对于车辆的位置的方案；利用超声信号进行终端设备相对于车辆的位置的测量，有利于得到精确的目标位置信息，且由于用户感知不到超声信号，从而在用户无感的情况下实现了用户相对于车辆的精确定位；此外，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
二、基于终端设备和各个音响之间的距离生成终端设备位于车辆内部的位置
具体的，请参阅图6，图6为本申请实施例提供的位置的获取方法的一种流程示意图，本申请实施例提供的位置的获取方法可以包括：

具体的，在一种情况中，若先由终端设备向车辆发送第一测量信号，车辆在接收到第一测量信号之后，再向终端设备发送第二测量信号，则步骤1008可以包括：车辆或终端设备将第二时间减去第一时间得到第一时间差值，将第四时间减去第三时间得到第二时间差值，再将第二时间差值减去第一时间差值得到目标时间差值，目标时间差值为超声信号在目标音响和终端设备之间传播两次的时长。车辆或终端设备根据目标时间差值，生成终端设备与目标音响之间的距离。
在另一种情况中，若先由车辆向终端设备发送第二测量信号，终端设备在接收到第二测量信号之后，再向车辆发送第一测量信号，则步骤1008可以包括：车辆或终端设备将第三时间减去第四时间得到第三时间差值，将第一时间减去第二时间得到第四时间差值，再将第四时间差值减去第三时间差值得到目标时间差值，目标时间差值为超声信号在目标音响和终端设备之间传播两次的时长。车辆或终端设备根据目标时间差值，生成终端设备与目标音响之间的距离。
本申请实施例中，由于车辆和终端设备可能会存在时钟不对齐的问题，则采用终端获取的两个时间计算差值，以及采用车辆获取的两个时间计算差值，从而避开了车辆和终端设备可能会存在时钟不对齐所导致的误差，以得到精准的距离。

更进一步地，若位于主驾驶位置的终端设备与位于副驾驶位置的终端设备发生位置交换时，车辆将会判断位于主驾驶位置的更新后的终端设备是否已经与车辆进行过配对，若判断结果为是，则将更新后的终端设备的屏幕内容投屏至车辆中控屏上；若判断结果为否，则向更新后的终端设备发送配对请求，以始终保持车辆中控屏上所显示的为位于主驾驶位置上的终端设备的屏幕内容。

实施例二
本申请实施例中，具体的，请参阅图18，图18为本申请实施例提供的位置的获取方法的一种流程示意图，本申请实施例提供的位置的获取方法可以包括：
2001、在车辆检测到满足第一触发条件和/或终端设备检测到满足第二触发条件的情况下，车辆和终端设备启动第一位置感知操作。
本申请实施例中，在一些应用场景中，当车辆检测到满足第一触发条件时，会启动第一位置感知操作，并向终端设备发送指示信息，该指示信息用于指示终端设备启动第一位置感知操作，第一位置感知操作用于测量终端设备位于车辆内部或者车辆外部。需要说明的是，实施例二中由车辆执行的步骤具体可以为由车辆中的处理器执行，也可以为由车辆中的车辆辅助设备执行，具体结合实际产品形态决定，后续均不再进行说明。
其中，当车辆检测到如下任一种或多种情况时，视为检测到满足第一触发条件：车辆检测到车辆停车；或者，车辆检测到终端设备与车辆之间的距离满足第一距离条件；或者，车辆获取到第一指令，第一指令用于触发车辆获取第一位置信息。
本申请实施例中，提供了第一触发条件的多种具体表现形式，扩展了本方案的应用场景，提高了本方案的实现灵活性。
针对车辆检测车辆停车这一场景。具体的，车辆中的车辆辅助设备上可以配置有各种类型的惯性测量单元，从而车辆辅助设备可以利用GPS或其他传感器来测量车辆的速度，利用加速计来测量车辆的加速度，利用陀螺仪来测量车辆的角速度。车辆中的车辆辅助设备将车辆的速度、加速度和角速度输入分类模型，得到分类模型输出的预测类别信息。
其中，该分类模型为已经执行过训练操作的模型，分类模型可以具体表现为神经网络，也可以表现为非神经网络的模型。作为示例，例如该分类模型可以具体表现为决策树、随机森林、极度随机树、支持向量机、K-临近(KNN)模型、逻辑回归模型或其他类型的分类模型等，此处不做穷举。
该预测类别信息指示车辆处于停止状态或移动状态；在一种实现方式中，分类模型输出的预测类别信息可以包括第一概率值和第二概率值，第一概率值用于指示车辆为停止状态的概率，第二概率值用于指示车辆为移动状态的概率；作为示例，例如预测类别信息包括0.3(也即第一概率值)和0.7(也即第二概率值)，0.3用于指示车辆为停止状态的概率为0.3，0.7用于指示车辆为移动状态的概率为0.7，则预测类别信息指示车辆处于移动状态。在另一种实现方式中，分类模型输出的预测类别信息可以为第一值或第二值，当分类模型输出的预测类别信息为第一值时，代表车辆处于停止状态，当分类模型输出的预测类别信息为第二值时，代表车辆处于移动状态，作为示例，例如第一值为0，第二值为1等，此处举例均仅为方便理解本方案，不用于限定本方案。
本申请实施例中，将车辆的速度、加速度和角速度输入分类模型中，以通过该分类模型确定车辆处于停止状态还是移动状态，避免了从车辆的控制系统中获取车辆的状态，保证了车辆的控制系统在终端设备的目标位置信息的测量过程中的独立性，有利于提高车辆运行过程的安全性。
针对车辆检测终端设备与车辆之间的距离这一场景。具体的，在一种实现方式中，车辆和终端设备上均可以配置有蓝牙，车辆可以采用广播的形式向外发送蓝牙信号，终端设备在接收到车辆发送的蓝牙信号后，可以计算终端设备与车辆之间的实际距离。在另一种实现方式中，也可以由终端设备向外发送蓝牙信号，车辆在接收到终端设备发送的蓝牙信号后，计算终端设备与车辆之间的实际距离。在另一种实现方式中，车辆和终端设备也可以利用无线通信技术(WIFI)计算终端设备与车辆之间的实际距离等，此处不对获取车辆和终端设备之间的实际距离的方式进行穷举。
车辆判断终端设备与车辆之间的距离是否满足第一距离条件；其中，第一距离条件可以为终端设备与车辆之间的距离是否小于预设距离，预设距离的取值可以为5米、3米、2米、1米或其他取值等等，此处不做限定。或者，第一距离条件可以为终端设备与车辆之间的距离逐渐变小直至满足预设距离等。
针对车辆获取到第一指令这一场景。具体的，在一些实现方式中，用户可以通过车辆辅助设备和/或车载电脑与车辆进行交互，当车辆获取到用户输入的预设操作时，可以触发车辆生成第一指令，预设操作包括但不限于获取车内终端设备列表的请求操作、切换与车 辆连接的终端设备的请求操作或其他类型的操作等等。
在另一些实现方式中，车辆可以接收终端设备发送的指示信息，前述指示信息用于请求获取终端设备的第一位置信息，车辆响应于接收到的前述指示信息，生成第一指令。
需要说明的是，当车辆检测到其他事件时，也可以视为触发第一触发条件，具体第一触发条件包含哪些事件需要结合实际应用场景灵活设定，此处不做限定。
在另一些应用场景中，当终端设备检测到满足第二触发条件的情况下，会启动第一位置感知操作，并向车辆发送指示信息，该指示信息用于指示车辆启动第一位置感知操作，第一位置感知操作用于测量终端设备位于车辆内部或者车辆外部。
其中，当终端设备检测到如下任一种或多种情况时，视为检测到满足第二触发条件：终端设备检测到车辆停车；或者，终端设备检测到终端设备与车辆之间的距离满足第一距离条件；或者，终端设备检测到终端设备的位移符合预设位移；或者，终端设备获取到第二指令，第二指令用于触发终端设备获取第一位置信息。
针对终端设备检测车辆停车这一场景。具体的，终端设备上可以预先配置有分类模型，车辆在获取到车辆的速度、加速度和角速度之后，可以发送给终端设备，终端设备将车辆的速度、加速度和角速度输入分类模型，得到分类模型输出的预测类别信息；分类模型和预测类别信息的具体含义可以参阅上述描述，此处不做赘述。
针对终端设备检测终端设备与车辆之间的距离这一场景，终端设备的具体实现方式，与车辆检测终端设备与车辆之间的距离这一场景的具体实现方式类似，均可参阅上述描述，此处不做赘述。
针对终端设备检测到终端设备的位移符合预设位移这一场景。具体的，终端设备上可以预先配置有至少一种类型的IMU，终端设备可以通过IMU获取到终端设备在水平方向和/或竖直方向上的位移，判断终端设备在水平方向和/或竖直方向上的位移是否符合预设位移，若判断结果为是，则确定满足第二触发条件。
其中，预设位移可以为终端设备在水平方向上的位移大于或等于预设阈值；或者，预设位移可以为终端设备在竖直方向上的位移大于或等于预设阈值；或者，预设位移可以包括终端设备在水平方向上的位移大于或等于预设阈值，且终端设备在竖直方向上的位移大于或等于预设阈值。当检测到终端设备的位移符合预设位移时，代表检测到终端设备可能存在上下车事件，具体预设位移的设定可以根据实际情况灵活确定，此处不进行详细限定。
针对车辆获取到第二指令这一场景。具体的，终端设备可以接收何亮发送的指示信息，前述指示信息用于请求终端设备的第一位置信息，车辆响应于接收到的前述指示信息，生成第二指令等，终端设备还可以在其他场景下获取到第二指令，此处不再一一进行列举。
需要说明的是，当终端设备检测到其他事件时，也可以视为触发第二触发条件，具体第二触发条件包含哪些事件需要结合实际应用场景灵活设定，此处不做限定。
2002、车辆向终端设备发送至少一个目标音频信号。
本申请实施例中，在车辆和终端设备均启动了第一位置感知操作后，车辆可以通过音响向终端设备发送至少一个目标音频信号。其中，目标音频信号可以为超声信号，超声信号所在频段可以为17KHZ-48KHZ，可选地，目标音频信号所在频段可以为17KHZ-22KHZ具 体目标音频信号的频率为多少可以结合实际应用产品确定，此处不做限定。作为示例，例如目标音频信号可以为线性调频(Chirp)信号、ZC(zadoff–chu)序列信号或其他类型的音频信号等，此处不做穷举。
进一步地，Chirp信号在时域的公式具体为：
Figure PCTCN2022128008-appb-000001
其中，φ 0为初始相位差，f 0为起始频率，c为常数。
ZC序列信号在时域的公式具体为：
Figure PCTCN2022128008-appb-000002
其中，j是一个虚数(imaginary)，j的平方等于-1；0<u<N ZC，gcd(N zc,u)＝1，c f＝N ZC mod 2，N ZC为ZC序列信号的信号长度，q的取值为整数。
上述音响可以为配置于车辆内部任意位置上的一个音响，作为示例，例如左上角、右上角、左下角、右下角或其他位置上的音响；可选地，若车辆配置有车辆辅助设备，上述音响也可以为车辆辅助设备上的音响。
为更直观地理解本方案，请参阅图19，图19为本申请实施例提供的位置的获取方法中音响的一个示意图，图19中以车辆辅助设备具体表现为车载智慧屏为例，车辆可以通过配置于车载智慧屏上的音响来测量终端设备位于车辆内部，还是位于车辆外部，应理解，图19中的示例仅为方便理解本方案，不用于限定本方案。
本申请实施例中，由于线性调频信号或者ZC序列信号为能量聚集型信号，选用线性调频信号或者ZC序列信号作为目标音频信号，有利于准确的估计每个目标音频信号所对应的至少一个到达时间，从而有利于得到准确的第一位置信息。
具体的，在一种实现方式中，车辆采用广播的形式，通过音响按照第一预设频率发送多个目标音频信号。其中，第一预设频率可以为车辆每隔d个采样点发送一个目标音频信号，作为示例，例如d的取值可以为880、1320、1760或其他取值等，具体可以结合实际场景灵活设定。
多个目标音频信号包括第一探测信号和第二探测信号，与目标音频信号对应的至少一个到达时间可以包括第一探测信号所对应的第一时间集合和第二探测信号所对应的第二时间集合，第一时间集合包括第一探测信号通过直射和/或反射到达终端设备的至少一个时间，第二时间集合包括第二探测信号通过直射和/或反射到达终端设备的至少一个时间，第一时间集合中最晚的时间和第二时间集合中最早的时间可以用于确定第一位置信息。
在另一种实现方式中，车辆通过音响发送一个或多个目标音频信号，其中，每个目标音频信号用于确定与该一个目标音频信号对应的目标时间集合，目标时间集合包括目标音频信号通过直射和/或反射到达终端设备的至少一个时间，目标时间集合中最早的时间和最晚的时间可以用于确定第一位置信息。
2003、终端设备获取与至少一个目标音频信号对应的至少一个到达时间，一个目标音频信号所对应的至少一个到达时间包括目标音频信号通过直射和/或反射到达终端设备的时间。
本申请实施例中，在一种情况中，当车辆采用广播的形式，通过音响按照第一预设频 率发送一个或多个目标音频信号时，对应的，终端设备能够在预设时长内获取到与每个目标音频信号对应的至少一个到达时间，一个目标音频信号所对应的至少一个到达时间包括目标音频信号通过直射和/或反射到达终端设备的时间。
具体的，终端设备上可以预先存储有目标音频信号的参数信息，例如目标音频信号所在频段、目标音频信号的振幅、强度或其他参数信息等。每个目标音频信号在通过直射和/或反射到达终端设备之后，终端设备可以通过带通滤波器对接收到的音频信号进行滤波，得到滤波后的信号，滤波后的信号所在频段与目标音频信号所在频段一致。
终端设备根据滤波后的信号，通过匹配滤波器得到滤波后的信号与目标音频信号之间的匹配度曲线，该匹配度曲线用于指示每个目标音频信号所对应的至少一个到达时间。
其中，匹配度曲线的横轴为时间，该时间可以通过采样点进行度量，也可以为通过秒进行度量；匹配度曲线的纵轴可以为滤波后的信号在每个时间点上的脉冲响应。该匹配度曲线包括的多个波峰中超过预设波峰阈值的每个波峰被认为是终端设备收到了一个目标音频信号，每个超过预设波峰阈值的波峰所对应的采样点被视为一个目标音频信号所对应的一个到达时间。
进一步地，预设波峰阈值可以为如下多种中的任意一种：在匹配度曲线中，d个采样点内(也即一个目标音频信号的发送周期内)最大的波峰值*a，a的取值范围为0.5-1；或者，在匹配度曲线中，d个采样点内(也即一个目标音频信号的发送周期内)所有纵轴方向上的值的平均值*b，b的取值范围是5-10；或者预设波峰阈值还可以设定为其它值，预设波峰阈值的取值可以结合实际产品形态灵活设定，此处举例仅为方便理解本方案，不用于限定本方案。
为了更直观地理解本方案，请参阅图20，图20为本申请实施例提供的位置的获取方法中匹配度曲线的一个示意图，图20中以示出5个目标音频信号通过直射和反射到达终端设备的信号，且预设波峰阈值为一个目标音频信号的发送周期内的最大的波峰值*a为例。由于每个目标音频信号可能通过直射和/或反射的方式到达终端设备，则车辆发射出一个目标音频信号后，终端设备可能接收到一个或多个目标音频信号，图20中以车辆每发送一个目标音频信号，终端设备均能收到一个目标音频信号为例，则终端设备能够获取到与每个音频信号对应的一个到达时间，应理解，图20中的示例仅为方便理解本方案，不用于限定本方案。
在另一种情况中，由于车辆为通过车内的音响发送目标音频信号，若车门和所有车窗均关闭，终端设备位于车辆外部且距离车辆较远位置时，车辆发出的目标音频信号可能无法到达终端设备，也即终端设备在预设时长内无法采集到任何一个目标音频信号。具体的，终端设备能够在预设时长内获取到与每个目标音频信号对应的零个到达时间，则终端设备可以生成与终端设备对应的第一位置信息，本应用场景中的第一位置信息用于指示终端设备位于车辆外部；可选地，终端设备可以将生成的前述第一位置信息发送给车辆。
其中，预设时长的取值范围可以为100ms–20000ms，作为示例，例如预设时长的取值可以为200ms、400ms、600ms或其他取值等等，此处不做穷举。终端设备获取与每个目标音频信号对应的到达时间的具体实现方式可以参阅上述描述。
2004、终端设备根据至少一个到达时间，生成与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部。
本申请实施例中，终端设备在得到每个目标音频信号对应的至少一个到达时间后，可以直接根据每个目标音频信号对应的至少一个到达时间，生成与终端设备对应的第一位置信息。可选地，终端设备也可以将每个目标音频信号对应的至少一个到达时间发送给车辆，由车辆生成与终端设备对应的第一位置信息。
为了更直观地理解本方案的原理，请参阅图21，图21为本申请实施例提供的位置的获取方法中匹配度曲线的两个示意图。图21包括(a)和(b)两个子示意图，图21的(a)子示意图示出的为当终端设备位于车辆内部时，车辆按照第一预设频率发出的3个目标音频信号到达终端设备后，终端设备所获取到的匹配度曲线的一个示意图；图21的(b)子示意图示出的为当终端设备位于车辆外部时，车辆按照第一预设频率发出的3个目标音频信号到达终端设备后，终端设备所获取到的匹配度曲线的一个示意图。图21的(a)子示意图和图21的(b)子示意图中，均以利用采样点作为时间度量单位，且预设波峰阈值为一个目标音频信号的发送周期内的最大的波峰值*a为例。
车辆发出一个目标音频信号后，目标音频信号可能会以直射的方式到达终端设备，也会经过周围环境的反射后到达终端设备，由于车辆内部的空间比较狭小且封闭，则如图21的(a)子示意图所示，当终端设备位于车辆内部时，一个目标音频信号所对应的至少一个到达时间较为集中。而车辆外部的空间较为开阔，则如图21的(b)子示意图所示，当终端设备位于车辆外部时，一个目标音频信号所对应的多个到达时间较为分散。因此，终端设备或车辆在得到每个目标音频信号所对应的至少一个到达时间后，能够确定终端设备位于车辆内部还是位于车辆外部，应理解，图21中的示例仅为方便理解本方案的实现原理的一个示例，不用于限定本方案。
具体的，在一种实现方式中，至少一个目标音频信号包括由车辆按照第一预设频率发出的多个目标音频信号，多个目标音频信号包括第一探测信号和第二探测信号，多个目标音频信号所对应的多个到达时间包括第一探测信号所对应的第一时间集合和第二探测信号所对应的第二时间集合，第一时间集合包括第一探测信号通过直射和/或反射到达终端设备的至少一个时间，第二时间集合包括第二探测信号通过直射和/或反射到达终端设备的至少一个时间，第一时间集合和第二时间集合中的到达时间之间的时间间隔用于确定第一位置信息。
其中，车辆发送第一探测信号的时间可以早于车辆发送第二探测信号的时间，或者，车辆发送第一探测信号的时间可以晚于车辆发送第二探测信号的时间。第一时间集合和第二时间集合在与多个目标音频信号对应的匹配度曲线上相邻，也即第一探测信号和第二探测信号为两个不同的目标音频信号，且相邻到达终端设备。
针对第一位置信息的判断条件。若第一时间集合和第二时间集合中的到达时间之间的时间间隔位于预设时间范围内，则第一位置信息指示终端设备位于车辆内部，预设时间范围的确定因素包括车辆发送两个相邻的目标音频信号之间的时间间隔；若第一时间集合和第二时间集合中的到达时间之间的时间间隔不位于预设时间范围内，则第一位置信息指示 终端设备位于车辆外部。
其中，预设时间范围所采用的时间度量单位可以包括采样点、毫秒、秒或其他时间度量单位等等，作为示例，例如预设时间范围可以为d-c个采样点至d+e个采样点，d个采样点为车辆发送两个目标音频信号之间的时间间隔。c和e的取值可以相同或不同，作为示例，例如c的取值和e的取值均与对接收到的目标音频信号进行处理时的采样率有关，作为示例，例如e的取值可以为50个采样点，例如c的取值可以为400个采样点至960个采样点之间，c和e还可以为其它取值，具体需要结合实际应用场景灵活确定，此处不做穷举。
本实现方式中，预设时间范围可以基于车辆发送两个相邻的目标音频信号之间的时间间隔确定，从而提供了一种简单的预设时间范围的确定方式。
针对第一时间集合和第二时间集合中的到达时间之间的时间间隔的含义。在一种情况中，第一时间集合和第二时间集合中的到达时间之间的时间间隔包括：第一时间集合中最晚的时间和第二时间集合中最早的时间之间的第一时间间隔。则步骤2004可以包括：终端设备或车辆根据第一时间集合中最晚的时间和第二时间集合中最早的时间之间的第一时间间隔，生成第一位置信息。
更具体的，终端设备或车辆获取第一时间集合中最晚的时间和第二时间集合中最早的时间之间的第一时间间隔，判断第一时间间隔是否位于预设时间范围内，若第一时间间隔位于预设时间范围内，则确定终端设备位于车辆内部；若第一时间间隔不位于预设时间范围内，则确定终端设备位于车辆外部。
本申请实施例中，提供了利用第一时间集合和第二时间集合中的到达时间之间的时间间隔，得到终端设备的第一位置信息的一种具体实现方式，操作简单，易于实现。
在另一种情况中，第一时间集合和第二时间集合中的到达时间之间的时间间隔包括：第一时间集合中位于中间的时间和第二时间集合中最早的时间之间的时间间隔；在另一种情况中，第一时间集合和第二时间集合中的到达时间之间的时间间隔包括：第一时间集合中位于中间的时间和第二时间集合中最晚的时间之间的时间间隔等，第一时间集合和第二时间集合中的到达时间之间的时间间隔还可以具体表现为其他含义等，具体可以结合实际应用产品灵活设定，此处不做限定。
在另一种实现方式中，步骤2004可以包括：终端设备或车辆可以获取每个目标音频信号所对应的目标时间集合，目标时间集合包括一个目标音频信号通过直射和/或反射到达终端设备的至少一个时间。终端设备或车辆获取目标时间集合中最早的时间和最晚的时间，并获取目标时间集合中最早的时间和最晚的时间之间的第二时间间隔，判断第二时间间隔是否大于或等于第一时间阈值，若判断结果为是，则确定终端设备位于车辆外部；若判断结果为否，则确定终端设备位于车辆内部。
需要说明的是，还可以通过其他方式来衡量与至少一个目标音频信号对应的至少一个到达时间的分散程度，与至少一个目标音频信号对应的至少一个到达时间越分散，则证明终端设备位于车辆外部；与至少一个目标音频信号对应的至少一个到达时间越紧密，则证明终端设备位于车辆内部，此处不对所有的实现方式一一进行列举。
可选地，终端设备在生成与终端设备对应的第一位置信息后，可以将前述第一位置信息发送给车辆；对应的，车辆在生成与终端设备对应的第一位置信息后，可以将前述第一位置信息发送给终端设备。
本申请实施例中，车辆发送多个目标音频信号，目标音频信号能够通过直射和/或反射到达终端设备，由于车辆内部的空间比较封闭，则一个目标音频信号经过直射和/或反射后得到的多个音频信号能够较为集中的到达终端设备，而车辆外部的空间相对于车辆内部的空间较为开阔，一个目标音频信号经过直射和/或反射后得到的多个音频信号会比较分散的到达终端设备，因此能够根据第一时间集合和第二时间集合之间的时间间隔确定终端设备位于车辆内部还是车辆外部，从而提供了一种测量用户相对于车辆的位置的方案；此外，音频信号可以通过车辆中自带的音响发出，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
本申请实施例还提供了另一种位置的获取方法来测量终端设备位于车辆内部还是车辆外部。请参阅图22，图22为本申请实施例提供的位置的获取方法的另一种流程示意图，本申请实施例提供的位置的获取方法可以包括：
2401、车辆按照第二预设频率向终端设备发送多个目标音频信号。
本申请实施例中，在车辆处于移动状态的情况下，车辆可以开始按照第二预设频率，通过音响采用广播的方式向外发送多个目标音频信号；由于车辆处于移动状态，则车辆能够检测到的终端设备一般位于车辆内部，则车辆按照第二预设频率发送多个目标音频信号均能够到达终端设备。
其中，第二预设频率和图18对应实施例中的第一预设频率可以相同或不同，目标音频信号的具体含义可以参阅图18对应实施例中的描述，判断车辆是否处于移动状态的具体实现方式可以参阅图18对应实施例中的描述，步骤2401的具体实现方式也可以参阅图18对应实施例中的描述，此处均不做赘述。
2402、在车辆处于移动状态下，终端设备获取与多个目标音频信号对应的多个第一到达时间，一个第一到达时间代表一个目标音频信号到达终端设备的时间。
本申请实施例中，在车辆处于移动状态下，车辆按照第二预设频率发送多个目标音频信号通过直射和/或反射后能够到达终端设备，终端设备可以获取到与每个目标音频信号对应的至少一个到达时间，前述步骤的具体实现方式可以参阅图18对应实施例中的描述。
终端设备可以根据与每个目标音频信号对应的至少一个到达时间，确定与每个目标音频信号对应的一个第一到达时间。其中，前述第一到达时间可以为与每个目标音频信号对应的至少一个到达时间可以仅包括一个到达时间；或者，前述第一到达时间可以为与每个目标音频信号对应的至少一个到达时间中最早的一个到达时间；或者，前述第一到达时间可以为与每个目标音频信号对应的至少一个到达时间中最晚的一个到达时间；或者，第一到达时间也可以选用与每个目标音频信号对应的至少一个到达时间中的其它到达时间，此处不做穷举。
终端设备重复执行上述操作，能够获取到与多个目标音频信号一一对应的多个第一到达时间，一个第一到达时间代表当终端设备位于车辆内部时，一个目标音频信号到达终端 设备的时间。
2403、终端设备在检测到满足第二触发条件的情况下，获取与至少一个目标音频信号对应的至少一个第二到达时间。
本申请实施例中，终端设备在检测到满足第二触发条件的情况下，获取与至少一个目标音频信号一一对应的至少一个第二到达时间。终端设备在检测到满足第二触发条件的具体实现方式可以参阅图18对应实施例中的描述，终端设备获取与至少一个目标音频信号一一对应的至少一个第二到达时间的具体实现方式，与终端设备获取与多个目标音频信号一一对应的多个第一到达时间的具体实现方式相同，区别在于，第一到达时间是在车辆处于移动状态下获得的，第二到达时间是在终端设备检测到满足第二触发条件后获得的。
2404、终端设备根据多个第一到达时间和至少一个第二到达时间，生成与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部。
本申请实施例中，终端设备在得到多个第一到达时间和至少一个第二到达时间之后，可以根据多个第一到达时间和至少一个第二到达时间，生成与终端设备对应的第一位置信息，第一位置信息用于指示终端设备位于车辆内部或车辆外部。
具体的，终端设备根据多个第一到达时间确定与第二到达时间对应的第一预测时间，第一预测时间指示在终端设备和车辆之间的相对位置不变的情况下，也即在终端设备位于车辆内部的情况下，目标音频信号到达终端设备的时间；根据第一预测时间和第二到达时间，生成第一位置信息。
更具体的，针对生成第一预测时间的过程。终端设备得到与多个目标音频信号一一对应的多个第一到达时间之后，由于车辆和终端设备之间存在时钟差值，则每个第一到达时间可以表现为如下公式
Figure PCTCN2022128008-appb-000003
其中，
Figure PCTCN2022128008-appb-000004
代表车辆发送的第i个目标音频信号到达终端设备的时间，i代表车辆发送的第i个目标音频信号，T代表车辆发送两个目标音频信号之间的时间间隔，b代表车辆和终端设备之间存在时钟差值。
终端设备可以根据与多个目标音频信号一一对应的多个第一到达时间，采用最小二乘法计算得到车辆和终端设备之间的时钟差值b。终端设备在检测到满足第二触发条件的情况下，可以得知车辆即将发送第k个目标音频信号，则可以通过公式
Figure PCTCN2022128008-appb-000005
计算得到第k个目标音频信号所对应的第一预测时间
Figure PCTCN2022128008-appb-000006
针对根据第一预测时间和第二到达时间，生成第一位置信息的过程。在一种实现方式中，终端设备可以计算第二到达时间与第一预设时间之间的第三时间间隔，判断第三时间间隔是否大于或等于第二时间阈值，若判断结果为是，则确定终端设备位于车辆外部；若判断结果为否，则确定终端设备位于车辆内部。
在另一种实现方式中，终端设备可以计算第二到达时间与第一预设时间之间的第三时间间隔Δt k，并将第三时间间隔Δt k与声音传播速度s相乘得到距离值d。终端设备判断距离d是否大于或等于预设距离阈值d threshold，若判断结果为是，则确定终端设备位于车辆外 部；若判断结果为否，则确定终端设备位于车辆内部。
本申请实施例中，由于当车辆处于移动状态时，能够持续收到音频信号的终端设备一定是位于车内的，从而可以根据获取到的多个第一到达时间来得到第一预测时间，进而根据生成的第一预测时间和实际的第二到达时间，来确定终端设备是位于车辆内部还是外部，仅需一个音响就能实现终端设备的第一位置信息的检测，进一步降低了本方案的实现难度，有利于扩展本方案的应用场景。
可选地，终端设备在生成与终端设备对应的第一位置信息后，可以将前述第一位置信息发送给车辆。
本申请实施例中，从而提供了一种测量终端设备是位于车辆内部还是位于车辆外部的另一种方案，提高了本方案的实现灵活性；且也即利用音频信号来测量终端设备是位于车辆内部还是位于车辆外部，无需在车辆或终端设备上增加额外的硬件，以避免了额外开销。
本申请实施例还提供了另一种位置的获取方法来测量终端设备位于车辆外部的具体位置，请参阅图23，图23为本申请实施例提供的位置的获取方法的另一种流程示意图，本申请实施例提供的位置的获取方法可以包括：
2501、车辆和终端设备启动车外位置感知操作。
本申请实施例中，在一些应用场景中，在车辆的运行过程中，当车辆确定需要获知终端设备在车辆外部的位置时，会启动车外位置感知操作，并向终端设备发送指示信息，前述指示信息用于指示终端设备启动车外位置感知操作，车外位置感知操作用于获取终端设备在车辆外部的具体位置。
作为示例，例如车辆检测到终端设备与车辆之间的距离小于预设阈值时，可能会需要获知终端设备位于车辆外部的具体位置。作为另一示例，例如车辆检测到终端设备与车辆之间的距离越来越小，则可能会需要获知终端设备位于车辆外部的具体位置，应理解，此处距离仅为方便理解本方案，不用于限定本方案。
2502、车辆通过第一音响向终端设备发送第一音频信号。
本申请实施例中，车辆上可以配置有至少三个音响，至少三个音响不位于一条直线上，至少三个音响包括第一音响、第二音响和第三音响，在启动车外位置感知操作之后，可以通过第一音响，采用广播的方式向终端设备发送第一音频信号。
2503、车辆通过第二音响向终端设备发送第二音频信号。
2504、车辆通过第三音响向终端设备发送第三音频信号。
本申请实施例中，车辆还可以通过第二音响，采用广播的方式向终端设备发送第二音频信号；通过第三音响，采用广播的方式向终端设备发送第三音频信号。其中，第一音频信号、第二音频信号和第三音频信号的具体表现方式均与目标音频信号的具体表现形式类似，可直接参阅图18对应实施例中的描述，此处不做赘述。进一步地，第一音频信号、第二音频信号和第三音频信号为信号强度一致的信号，也即第一音频信号、第二音频信号和第三音频信号的音量相同。对于第一音响、第二音响和第三音响的位置可以参阅实施例一中的介绍，需要说的是，实施例二中的音响可以为位于车辆内部的音响，也可以为位于车辆外部的音响。
具体的，在一种实现方式中，车辆可以同时执行步骤2502至2504，则第一音频信号、第二音频信号和第三音频信号需要采用不同的音频信号，不同的音频信号的具体含义可以参阅实施例一种的描述，此处不再一一进行赘述。
在另一种实现方式中，车辆可以先执行步骤2502，在预设时间间隔后再执行步骤2503，在预设时间间隔后再执行步骤2504，则第一音频信号、第二音频信号和第三音频信号可以为相同的音频信号，也可以为不同的音频信号。
可选地，车辆还可以通过第四音响向终端设备发送第四音频信号，对应的，终端设备能够得到接收到的第四音频信号的第四信号强度，需要说明的是，车辆还可以利用更多的音响向终端设备发送音频信号，具体采用的音响数量以及每个音响的位置可以结合实际情况灵活设定，此处不做限定。

2505、终端设备根据接收到的第一音频信号的第一信号强度、接收到的第二音频信号的第二信号强度和接收到的第三音频信号的第三信号强度，生成与终端设备对应的第二位置信息，第二位置信息用于指示终端设备位于车辆外部的位置。
本申请实施例中，由于当终端设备位于车辆外部的不同位置上时，终端设备与各个音响之间的距离关系不同，音频信号传播越远，终端设备接收到的音频信号的强度越小，则终端设备可以根据接收到的第一音频信号的第一信号强度、接收到的第二音频信号的第二信号强度和接收到的第三音频信号的第三信号强度，生成与终端设备对应的第二位置信息。终端设备可以将终端设备的第二位置信息发送给车辆。
为了更直观地理解本方案的原理，请参阅图8b和图24，图8b为本申请实施例提供的位置的获取方法中车辆外部的位置的一个示意图，图24为本申请实施例提供的位置的获取方法的一个原理示意图。先参阅图8b，图8b中以将车辆外部分为Z1至Z5这5个区域为例，应理解，图8b中的示例仅为方便理解本方案，不用于限定本方案。
再参阅图24，图24需要结合图8b进行理解，图24中以终端设备位于Z4区域为例，则音响1距离终端设备最远，音响2距离终端设备次之，音响3距离终端设备最近，则音响1发出的音频信号到达终端设备时的信号强度最弱，音响1发出的音频信号到达终端设备时的信号强度次之，音响1发出的音频信号到达终端设备时的信号强度最强，反过来推，若终端设备接收到的三个音响发送的三个音频信号的强度符合前述设定，则证明终端设备位于Z4区域，应理解，图24中的示例仅为方便理解本方案的实现原理的一个示例，不用于限定本方案。
具体的，终端设备上可以预先存储有与车辆外部的多个区域一一对应的多组预设强度信息，车辆外部的目标区域(车辆外部的任意一个区域)所对应的一组预设强度信息包括与至少三个音响一一对应的至少三个目标强度值，一个目标强度值代表当终端设备位于目标区域的中心点时接收到的一个音响发出的音频信号的强度值。作为示例，例如车辆外部被划分为Z1至Z5这5个区域，则终端设备上预先存储有与5个区域一一对应的5组强度信息。
终端设备在获取到第一信号强度、第二信号强度和第三信号强度之后，也即得到了一组实际强度信息，终端设备计算实际强度信息与多组预设强度信息中每组预设强度信息之间的距离，并从多组预设强度信息中选择与实际强度信息距离最近的一组预设强度信息，将距离最近的一组预设强度信息所对应的区域确定为终端设备所在区域。其中，前述距离可以为欧式距离、马氏距离或其他类型的距离等，此处不做穷举。
本申请实施例中，由于当终端设备位于车辆外部的不同位置上时，终端设备与各个音响之间的距离关系不同，音频信号传播越远，终端设备接收到的音频信号的强度越小，则第一信号强度、第二信号强度和第三信号强度能够分别反应终端设备与第一音响、第二音响以及第三音响之间的距离关系，因此能够基于第一信号强度、第二信号强度和第三信号强度得到终端设备位于车辆外部的具体位置，提供了测量终端设备在车辆外部的具体位置的又一实现方式，提高了本方案的实现灵活性。
可选地，车辆在得到终端设备的第二位置信息后，第二位置信息用于供车辆从车辆包括的多个组件中确定与终端设备之间距离最近的组件，以控制与终端设备之间距离最近的组件执行预设操作。其中，组件可以为车门、车灯、后备箱或其他车辆组件，预设操作可以为解锁车门、打开车门、解锁后备箱、打开车灯或其他操作等等，此处不做限定。
为更直观地理解本方案，请参阅图25，图25为本申请实施例提供的位置的获取方法的一个应用场景图。如图25所示，当车辆确定终端设备位于车辆外部的Z1区域时，可以解锁左前侧车门；当车辆确定终端设备位于车辆外部的Z2区域时，可以解锁左后侧车门；当车辆确定终端设备位于车辆外部的Z5区域时，可以解锁后备箱，应理解，图25仅为方便理解本方案的一个示例，不用于限定本方案。
作为另一示例，例如在夜间时，当车辆确定终端设备位于车辆外部的Z1区域时，还可以打开左前侧的车灯，以为用户提供照明；作为另一示例，例如当车辆确定终端设备位于车辆外部的Z2区域时，还可以自动打开车门等等，具体此处不做一一穷举。

具体的，请参阅图32，图32为本申请实施例提供的音频流的处理方法的一种流程示意图，本申请实施例提供的音频流的处理方法可以包括：
3701、第一终端设备与车辆建立连接，将第一类别和第二类别的音频流的播放设备由第一终端设备切换至车辆。
本申请实施例中，若第一终端设备与车辆首次建立连接，则第一终端设备可以采用蓝牙、无线宽带(wireless fidelity，WIFI)或其他技术等对周围的电子设备进行扫描，若发现预设距离阈值内存在至少一个车辆，则第一终端设备可以向每个车辆发送连接请求，以触发第一终端设备与车辆之间的配对操作。若第一终端设备与至少一个车辆中的一个车辆之间配对成功，则第一终端设备与前述车辆成功建立连接；若第一终端设备与至少一个车辆中的一个车辆之间配对失败，则第一终端设备与前述车辆无法建立连接。
具体的，车辆在接收到第一终端设备发送的连接请求后，响应于接收到的连接请求，生成车辆的个人识别码(personal identification number，PIN)，并向第一终端设备发送响应消息。第一终端设备在接收到响应消息后，可以向车辆发送PIN码。车辆将第一终端设备发送的PIN码和生成的PIN码进行匹配，若匹配成功，则证明第一终端设备与该车辆配对成功；若匹配失败，则证明第一终端设备与该车辆配对失败。
若第一终端设备与车辆并非首次建立连接，则第一终端设备可以采用蓝牙、无线宽带(wireless fidelity，WIFI)或其他技术等对周围的电子设备进行扫描，若发现预设距离阈值内存在至少一个已经进行过配对的车辆，则第一终端设备可以向前述车辆发送连接请求，前述车辆响应于获取到的连接请求，与第一终端设备建立连接。
在第一终端设备与车辆处于连接状态的过程中，第一终端设备可以向车辆发送同步数据，对应的，车辆接收第一终端设备发送的同步数据，以实现第一终端设备通过车辆执行如下任一种或多种任务：播放音频流、播放视频、导航、视频通话、通话或其他任务等等，此处不做穷举。
第一终端设备在与车辆建立连接之后，可以将第三类别的音频流的播放设备由第一终端设备切换至车辆。其中，第三类别包括至少两个类别的音频流，该至少两个类别的音频流包括第一类别和第二类别，具体第三类别的音频流包括哪些类别的音频流可以结合实际应用场景灵活确定，作为示例，例如第三类别可以包括媒体、通话或其他类型的音频流等；对于第一类别和第二类别的含义将在后续步骤中进行说明，此处暂时不做解释。
具体的，第一终端设备上可以存储有指示信息，该指示信息记录有第三类别的音频流包括的至少两个类别的音频流采用哪种播放设备，则第一终端设备可以更新该指示信息，更新前的指示信息指示第三类别的音频流的播放设备为第一终端设备，更新后的指示信息指示第三类别的音频流的播放设备为车辆。
作为示例，例如第三类别的音频流可以有第一终端设备的扬声器、第一终端设备的听筒、与第一终端设备处于连接状态的车辆或其他可能的播放设备等，此处不做穷举。
进一步地，上述指示信息具体可以表现为表格、标志位或其他信息类型等等，此处不做穷举。
3702、在第一终端设备与车辆处于连接状态的过程中，第一终端设备或车辆检测到第一终端设备从车内移动至车外。
本申请实施例中，在第一终端设备与车辆处于连接状态的过程中，第一终端设备或车辆可以检测到第一终端设备在预设时间段内的第一位置信息，根据第一终端设备在预设时间段内的第一位置信息，可以得知第一终端设备是否由从车内移动至车外。
可选地，在第一终端设备与车辆处于连接状态，且第一终端设备通过车辆进行投屏的过程中，第一终端设备或车辆检测到第一终端设备从车内移动至车外。
其中，第一终端设备指的是与车辆已经建立连接且位于车内的终端设备；可选地，第一终端设备指的是与车辆已经建立连接、通过车辆执行投屏操作且位于车内的终端设备。
预设时间段的取值范围例如可以为10秒至2分钟，作为示例，例如预设时间段的取值可以为20秒、370秒、45秒、1分钟、80秒、90秒或其他取值等等，具体预设时间段的取值可以结合实际应用产品灵活设定，此处不做限定。
更具体的，在一种实现方式中，可以采用实施例二中提供的方案来获取预设时间段内第一终端设备的第一位置信息，也即在实施例二中，当车辆检测到满足第一触发条件和/或第一终端设备检测到满足第二触发条件的情况下，车辆和第一终端设备启动第一位置感知操作，并在该预设时间段内持续获取第一终端设备的第一位置信息。若第一终端设备或车辆检测到第一终端设备从车内移动至车外，则触发进入步骤3702，若第一终端设备或车辆检测到第一终端设备一直位于车内，则第一终端设备可以继续通过车辆进行投屏。
具体的，车辆按照预设频率发送多个目标音频信号，其中，多个目标音频信号包括第一探测信号和第二探测信号，至少一个到达时间包括第一探测信号所对应的第一时间集合和第二探测信号所对应的第二时间集合，第一时间集合包括第一探测信号通过直射和/或反射到达第一终端设备的至少一个时间，第二时间集合包括第二探测信号通过直射和/或反射到达第一终端设备的至少一个时间；第一终端设备根据第一时间集合和第二时间集合中的到达时间之间的时间间隔，生成与终端设备对应的第一位置信息，第一位置信息用于指示第一终端设备位于车辆内部或车辆外部；根据第一终端设备在预设时间段内的第一位置信息，确定第一终端设备从车内移动至车外。
需要说明的是，上述步骤的具体实现方式可以参阅实施例二中的描述，此处不做赘述。
在另一种实现方式中，当车辆检测到满足第一触发条件和/或第一终端设备检测到满足第二触发条件的情况下，车辆或第一终端设备可以基于超宽带(ultra wide band，UWB)技术、蓝牙技术或其他技术，在预设时间段内持续获取第一终端设备和车辆之间的距离，根据预设时间段内第一终端设备和车辆之间的距离，确定第一终端设备在预设时间段内的第一位置信息。其中，若第一终端设备和车辆之间的距离大于或等于预设距离阈值，则证明第一终端设备位于车外；若第一终端设备和车辆之间的距离小于预设距离阈值，则证明第一终端设备位于车内。
需要说明的是，车辆或第一终端设备还可以通过其他技术来生成第一终端设备的第一位置信息，此处不再一一进行列举。
此外，若由车辆检测到第一终端设备从车内移动至车外，则车辆会向第一终端设备发送指示信息，该指示信息用于指示第一终端设备在该预设时间段内由车内移动至车外。或者，若是由车辆检测到第一终端设备一直位于车内，则车辆会向第一终端设备发送指示信息，该第一指示信息用于指示第一终端设备在该预设时间段内一直位于车内。
可选地，为了保证用户在通话过程的良好体验，则可以在第一终端设备与车辆处于连接状态时，若第一终端设备通过车辆播放的目标音频流所对应的目标类别为通话，则在用 户通过第一终端设备进行通话的过程中，第一终端设备和车辆可以不获取第一终端设备的第一位置信息；也即在用户通过第一终端设备进行通话的过程中，第一终端设备和车辆不会检测第一终端设备是否由车内移动至车外。
若用户想要将类别为通话的目标音频流的播放设备由车辆切换为其他电子设备，需要用户主动输入第一切换操作，第一终端设备或车辆响应于接收到的第一切换操作，将目标类别为通话的目标音频流的播放设备切换至与第一切换操作对应的电子设备。
其中，类别为通话的音频流可以包括：通过即时通信类的应用程序进行通话时所产生的音频流、通过即时通信类的应用程序进行视频时所产生的音频流或其他被归类为通话的音频流等。
具体的，针对用户主动输入第一切换操作的方式。在一种实现方式中，用户可以通过第一终端设备的显示界面输入第一切换操作，或者，用户可以通过车辆的显示界面输入第一切换操作。为了更直观地理解本方案，请参阅图33，图33为本申请实施例提供的音频流的处理方法中第一切换操作的接收界面的一种示意图。图33中展示的为车辆的中控屏的显示界面的一个示例，如图所示，类型为通话的目标音频流的当前播放设备为车辆中配置的音响，图33中还示出了终端设备的扬声器、终端设备的听筒和与终端设备连接的蓝牙三种方式，则用户可以通过点击显示界面上的图标的方式输入第一切换操作，应理解，图33中的示例仅为方便理解本方案，不用于限定本方案。
在另一种实现方式中，在第一终端设备通过车辆播放类型为通话的目标音频流的过程中，若第一终端设备检测到用户把第一终端设备贴近耳朵，则可以视为用户通过第一终端设备输入第一切换操作，且该第一切换操作所对应的播放设备为第一终端设备的听筒。
作为示例，例如当用户把第一终端设备贴近耳朵时，第一终端设备可以通过电容屏进行耳廓贴近检测，以检测到用户把第一终端设备贴近耳朵。或者，第一终端设备可以通过陀螺仪、重力传感器、接近光传感器等器件检测到自身被拿起且靠近耳边的动作，从而判断出用户把第一终端设备贴近耳朵。需要说明的是，第一终端设备还可以通过其他技术检测到用户是否将第一终端设备贴近耳朵，此处举例仅为证明本方案的可实现性，不用于限定本方案。
进一步可选地，在用户通过第一终端设备进行的通话结束后，可以触发第一终端设备或车辆获取第一终端设备的位置信息，若检测到第一终端设备位于车外，则可以将由车辆播放的至少一种类型的音频流的播放设备由车辆切换至第一终端设备；或者，也可以将除了媒体之外的其他类型的音频流的播放设备由车辆切换至第一终端设备。
在检测第一终端设备位于车外之后，车辆的中控屏的显示界面可以切换至离车模式。在离车模式下车辆的中控屏的显示界面所展示的内容可以为如下任一种或多种组合：黑屏、壁纸、显示时间或插画、提示信息或其他信息；前述提示信息用于指示车辆的中控屏现在的状态，需要说明的是，在离车模式下车辆的中控屏上还可以展示其他信息，具体展示哪些信息可以结合实际产品形态灵活设定，此处不做穷举。
本申请实施例中，在第一终端设备与车辆处于连接状态的过程中，当需要进行拾音操作时，具体采用第一终端设备上的拾音设备还是采用车辆的拾音设备，可以根据通话这一 类别的音频流所采用的播放设备决定。也即若第一终端设备通过车辆播放通话这一类别的音频流，则第一终端设备可以通过车辆进行拾音；若第一终端设备通过第一终端设备播放通话这一类别的音频流，则第一终端设备可以通过第一终端设备进行拾音。其中，拾音设备具体可以采用麦克风或其他类型的拾音设备等。
本申请实施例中，在第一终端设备与车辆处于连接状态的过程中，在第一终端设备一直位于车内的过程中，若第一终端设备检测到耳机与第一终端设备之间建立了连接，则在一种实现方式中，可以自动将第三类别包括的所有类别的音频流的输出设备切换为耳机；在另一种实现方式中，第一终端设备可以输出询问信息，该询问信息用于询问是否将所有类别的音频流的输出设备切换为耳机。第一终端设备可以响应用户输入的切换操作，将所有类别的音频流的输出设备均切换为耳机。
3703、第一终端设备判断是否存在正在通过车辆播放的目标音频流，若判断结果为是，则进入步骤3704；若判断结果为否，则将第三类别的音频流的播放设备由车辆切换至第一终端设备，第三类别包括第一终端设备通过车辆播放的音频流所对应的所有类别。
本申请的一些实施例中，第一终端设备在确定第一终端设备由车内移动至车外时，可以判断第一终端设备是否存在正在通过车辆播放的目标音频流，若判断结果为是，则触发进入步骤3704；若判断结果为否，则触发将第三类别的音频流的播放设备均由车辆切换至第一终端设备，第三类别包括第一终端设备通过车辆播放的音频流所对应的所有类别。
具体的，在第一终端设备与车辆处于连接状态的过程中，在第一终端设备由车内移动至车外的过程中，若第一终端设备未通过车辆播放任何音频流，则可以将第三类别包括的所有类别的音频流的播放设备均由车辆切换至第一终端设备，车辆的中控屏的显示界面可以进入离车模式。
为了更直观地理解本方案，请参阅图34，图34为本申请实施例提供的音频流的处理方法中离车模式的一种示意图。图34包括(a)、(b)和(c)三个子示意图，图34的(a)、(b)和(c)三个子示意图示出的均为将第三类别包括的所有类别的音频流的播放设备均由车辆切换至第一终端设备后，车辆的中控屏的显示界面，应理解，图34中的示例仅为方便理解本方案，不用于限定本方案。
3704、第一终端设备获取与车辆正在播放的目标音频流对应的目标类别。
本申请实施例中，在第一终端设备与车辆处于连接状态时，当检测到第一终端设备从车内移动至车外，且第一终端设备存在正在通过车辆播放的目标音频流时，第一终端设备可以获取与车辆正在播放的目标音频流对应的目标类别。

3705、第一终端设备判断目标类别是否为第一类别，若判断结果为是，则进入步骤3706；若判断结果为否，则进入步骤3709。
本申请实施例中，第一终端设备在获取到车辆正在播放的目标音频流所对应的目标类别后，可以判断目标类别是否为第一类别，若目标类别为第一类别，则进入步骤3706，若目标类别不是第一类别，则进入步骤3709。
其中，第一类别可以包括媒体，类别为媒体的音频流可以包括：音乐、视频、游戏类应用程序产生的音频流、即时通信类应用程序中的音频、或其他归类为媒体的音频流等等，此处不做穷举。
本申请实施例中，由于类别为媒体的音频流一般娱乐性较强，且对隐私性的要求较弱，当第一终端设备由车内移动至车外后，只有当车辆正在播放的目标音频流的类型为媒体的情况下，才会由车辆继续播放该目标音频流，既保证了车内其他人员的娱乐性，又尽量避免了用户的隐私泄露。
当然，本申请实施例中，第一类别也可以是除了媒体以外的其它类别，此处不做限定。
3706、第一终端设备继续向车辆发送目标音频流，然后进入步骤3707。
本申请实施例中，步骤3705为可选步骤，若不执行步骤3705，则可以在执行完步骤3704后进入步骤3706，第一终端设备可以继续向车辆发送目标音频流，对应的，车辆在接收到第一终端设备发送的目标音频流后，会继续播放该目标音频流，也即在第一终端设备由车内移动至车外后，目标类别的音频流的播放设备依旧为车辆。

可选地，车辆在将导航目的地更新为该目标地址之后，还可以输出通知信息；前述通知信息用于告知用户导航目的地更新成功；或者，车辆在确定不修改车辆的导航目的地之后，可以输出通知信息，前述通知信息用于告知用户导航目的地未发生改变。
其中，车辆输出上述通知信息的方式可以为如下任一种或多种的组合：以语音的方式 输出该通知信息、以文本框的形式输出该通知信息、以指示灯的形式输出该通知信息或其他方式输出该通知信息等等，此处不做限定。
为了更直观地理解本方案，请参阅图45，图45为本申请实施例提供的地址的处理方法中输出通知信息的一种示意图。图45中以通过语音方式搭配文本框的方式输出该通知信息为例，应理解，图45中的示例仅为方便理解本方案，不用于限定本方案。
本申请实施例中，在检测到第二终端设备位于车内，且第二终端设备上展示有地址信息的情况下，可以输出第二信息，该第二信息用于提示用户输入“发送目标地址”的目标操作，也即第二终端设备为基于用户的意愿发送目标地址；此外，只有在检测到第二终端设备位于车内时，才能够实现“发送目标地址”这一操作，避免了其他设备对第一终端设备的干扰，有利于提高车辆驾驶过程的安全性。
在第二终端设备执行步骤4502，且不执行步骤4503的情况下，在一种实现方式中，若第二终端设备所对应的第一位置信息指示第二终端设备位于车内，且第二终端设备正在显示界面上显示目标地址，当第二终端设备获取到用户输入的第一触发操作时，响应于接收到的第一触发操作，发送目标地址，发送的目标地址用于指示将目标地址作为车辆进行导航时的目的地，“第二终端设备发送目标地址”的具体实现方式可以参阅上述描述，此处不做赘述。
其中，第一触发操作可以为上下摇晃第二终端设备、左右摇晃第二终端设备、通过第二终端设备的界面输入预设手势操作或其他操作等等，此处不做穷举；预设手势操作可以为“Z”字形手势操作、“O”字型手势操作、“对勾”型手势操作、三指向上滑动操作或其他手势操作等等，此处不做穷举。

本申请实施例中，在检测到第二终端设备位于车内，且第二终端设备上展示有地址信息的情况下，还可以通过用户主动输入的第一触发操作，触发发送目标地址，以将目标地址确定为车辆的导航目的地，扩展了发送目标地址的触发场景，也即扩展了本方案的应用场景，提高了本方案的实现灵活性。
在另一种实现方式中，若第二终端设备所对应的第一位置信息指示第二终端设备位于车内，且第二终端设备正在显示界面上显示目标地址，则可以直接触发第二终端设备发送目标地址，发送的目标地址用于指示将目标地址作为车辆进行导航时的目的地。
在第二终端设备不执行步骤4502和4503的情况下，则在一种实现方式中，若检测到第二终端设备正在显示界面上显示目标地址，则第二终端设备可以输出第二信息，第二信息用于提示用户输入目标操作。在第一终端设备与车辆处于连接状态的过程中，响应于获取到的目标操作，第二终端设备发送目标地址，发送的目标地址用于指示将目标地址作为车辆进行导航时的目的地。
在另一种实现方式中，若检测到第二终端设备正在显示界面上显示目标地址，当第二 终端设备获取到用户输入的第一触发操作时，响应于接收到的第一触发操作，发送目标地址，发送的目标地址用于指示将目标地址作为车辆进行导航时的目的地。
本申请实施例中，由于第一终端设备在与车辆处于连接状态的过程中，第一终端设备一般为位于主驾驶位置的终端设备，若只能通过第一终端设备修改车辆导航时的目的地，则很大概率是由驾驶员执行该修改操作，会增加驾驶过程的风险；本方案中可以由第二终端设备修改车辆导航时的目的地，从而有利于提高驾驶过程的安全性，以及修改导航目的地的效率。

本申请实施例中，车辆上可以存储有至少一种目标数据和/或车辆上运行有至少一种目标业务能够流转至车内的终端设备，第三终端设备可以获取到用户输入的第三触发操作，
其中，该第三触发操作用于将车辆上存储的目标数据和/或车辆上运行的目标业务流转至车内的终端设备。作为示例，例如第三触发操作可以为左右晃动第三终端设备、上下晃动第三终端设备、通过第三终端设备的界面输入预设手势操作、通过第三终端设备输入语音指令或其他类型的第三触发操作等等，此处不做穷举。
5402、第三终端设备判断第三终端设备是否位于车内，若判断结果为是，进入步骤5403；若判断结果为否，终止目标数据和/或目标任务的流转操作。
本申请实施例中，第三终端设备在获取第三触发操作之后，可以触发获取第三终端设备的第一位置信息，“获取第三终端设备的第一位置信息”与“获取第一终端设备的第一位置信息”的具体实现方式类似，可直接参阅实施例三中的上述描述，此处不做赘述。
第三终端设备根据第三终端设备的第一位置信息来判断第三终端设备是否位于车辆内部，若判断结果为是，则进入步骤5403；若判断结果为否，则终止目标数据和/或目标任务的流转操作。
5403、第三终端设备向车辆发送第二流转请求，第二流转请求用于请求将目标数据和/或目标业务流转至第三终端设备。
本申请实施例中，在第三终端设备的第一位置信息指示第三终端设备位于车内的情况下，第三终端设备可以向车辆发送第二流转请求。对应的，车辆在接收到第二流转请求后，第二流转请求用于请求将目标数据和/或目标业务流转至第三终端设备。

本申请实施例中，提供了车内的终端设备与车辆之间信息流转的更多的应用场景，扩展了本方案的应用场景；车辆上存储的数据和/或运行的业务只能流转至车内的终端设备，既有利于保护车辆数据的隐私性，又避免了车辆附近的用户给车辆造成的干扰。
六、当车内的终端设备进行通话的过程中，降低车辆播放音频流时的音量
本申请实施例中，车辆内部有多个终端设备，其中一个终端设备与车辆处于连接状态，若车辆内部的其他终端设备不与车辆处于连接状态，则车辆不能及时的知晓车内每个终端设备的状态。若车辆在播放音频流的过程中，车内的其他终端设备进行通话，则车辆播放的音频流会给其他终端设备造成干扰，因此在车内的其他终端设备进行通话时，需要降低车辆播放音频流时的音量。
需要说明的是，此处举例仅为方便理解本方案而提供的一个典型的应用场景，在具体实现中，无论该终端设备是否与车辆处于连接状态，只要该终端设备位于车辆内部，均可以采用本方案。
具体的，请参阅图50，图50为本申请实施例提供的音量的处理方法的一种流程示意图，本申请实施例提供的音量的处理方法可以包括：
5501、终端设备获取终端设备的第一位置信息，终端设备的第一位置信息用于指示该终端设备位于车内还是车外。
本申请实施例中，当终端设备进行通话时，在终端设备向车辆发送第一状态信息之前，可以触发获取终端设备的第一位置信息，终端设备的第一位置信息用于指示该终端设备位于车内还是车外。其中，“终端设备的第一位置信息”的具体获取方式可以参阅实施例三终端上述描述，此处不做赘述。
5502、在终端设备位于车内的情况下，当终端设备进行通话时，向车辆发送第一状态信息，该第一状态信息用于供车辆得到与所播放的音频流对应的目标音量。
本申请实施例中，若终端设备的第一位置信息指示终端设备位于车外，则终端设备终止后续操作。若终端设备的第一位置信息指示终端设备位于车内，则当终端设备进行通话时，可以向车辆发送第一状态信息。其中，该第一状态信息用于供车辆得到与所播放的音频流对应的目标音量；作为示例，例如该第一状态信息具体可以表现为Call_ON信号，用于告知车辆该终端设备处于通话状态。
具体的，在一种实现方式中，终端设备可以仅在开始通话时，向车辆发送一次该第一状态信息。在另一种实现方式中，终端设备在通话过程中，可以按照预设频率向车辆发送多个第一状态信息；对应的，车辆需要持续监听终端设备发出的第一状态信息。
其中，预设频率可以为1赫兹(HZ)、2HZ、每10秒发送一次、每20秒发送一次、每 分钟发送一次或其他频率等等，此处不做穷举。
可选地，终端设备可以获取车辆的当前运行状态，若车辆处于移动状态，则终端设备可以仅在开始通话时，向车辆发送一次该第一状态信息。若车辆处于停车状态，则在终端设备的通话过程中，可以按照预设频率向车辆发送多个第一状态信息。需要说明的是，终端设备获取车辆为移动状态还是停车状态的具体实现方式可以参阅上述实施例中的描述，此处不做赘述。
5503、车辆响应于接收到的第一状态信息，确定与所播放的音频流对应的目标音量，目标音量小于或等于预设音量阈值。
本申请实施例中，车辆响应于接收到的第一状态信息，可以获取与所播放的音频流对应的第一播放音量(也即车辆当前所采用的实际音量)，判断获取到的第一播放音量是否大于预设音量阈值，若判断结果为否，则车辆可以不再调整车辆播放音频流时所采用的音量；若判断结果为是，则将车辆播放音频流时所采用的目标音量调整至预设音量阈值。其中，预设音量阈值的度量单位可以为分贝、音量档位或其他类型的度量单位等，此处不做限定。作为示例，例如预设音量阈值的音量档位为0或1，作为另一示例，例如预设音量阈值的分贝数为0，应理解，此处举例仅为方便理解本方案，不用于限定本方案。
可选地，在一种实现方式中，若终端设备可以仅在开始通话时，向车辆发送一次该第一状态信息，则当终端设备通话结束时，可以向车辆发送第二状态信息，该第二状态信息用于供车辆将第一播放音量确定为与所播放的音频流对应的音量。作为示例，例如该第二状态信息具体可以表现为Call_Off信号，用于告知车辆该终端设备处于通话结束状态。
对应的，车辆在接收到第二状态信息后，可以触发将播放音频流时所采用的音量重新调整回第一播放音量。进一步地，若车辆当前所采用的播放音量为第一播放音量，则车辆不需要进行音量调整。
在另一种实现方式中，若终端设备在通话过程中，按照预设频率向车辆发送多个第一状态信息，则当终端设备通话结束时，可以向车辆发送第二状态信息，该第二状态信息用于供车辆将第一播放音量确定为与所播放的音频流对应的音量。
在另一种实现方式中，若终端设备在通话过程中，按照预设频率向车辆发送多个第一状态信息，则当终端设备通话结束时，可以停止向车辆发送第一状态信息。对应的，当车辆监听不到第一状态信息，就可以触发将第一播放音量重新确定为播放音频流时所采用的音量。
本申请实施例中，由于若车辆处于停车状态，则可能会存在用户携带终端设备离车的场景，则终端设备在通话过程中，按照预设频率向车辆发送多个第一状态信息，从而当车辆监听不同第一状态信息时，就可以及时将播放音频流时所采用的音量恢复至第一播放音量，也即能够保障在用户携带终端设备下车后，车辆能及时恢复所播放的音频流的音量，也即不仅能够实现自动降低车辆播放音频流时的音量，还可以自动提高车辆播放音频流时的音量。
本申请实施例中，当车辆内部的终端设备进行通话时，能自动降低车辆播放的音频流的音量，从而可以避免车辆播放的音频给车内用户进行通话时造成困扰；且无需增加额外 的硬件设备，就可以实现前述功能；此外，只有当位于车辆内部的终端设备进行通话时，才会触发降低车辆所播放的音频的音量，避免了车辆外部的终端设备所带来的干扰。
