附图说明
本发明上述的以及其他的特征、性质和优势将通过下面结合附图和实施例的描述而变的更加明显，在附图中相同的附图标记始终表示相同的特征，其中：

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释发明，并不用于限定发明。
如前所述，当用户需要使用汽车扬声器作为音频输出设备时，只能采用车内座舱交互方式，目前并没有用户在车外时与汽车进行直接语音交互方式。所谓的车外直接语音交互方式，是指用户对车辆进行语音输入，车辆通过外置扬声器(包括但不限于振子发声面板)等方式对外播放声音，从而将车辆作为一个移动的音响，使得车辆满足如K歌、实时演讲等使用场景。
但是，一方面，由于目前车辆对外播放也只能通过车内扬声器进行相关音频的输出播放，用户在车外很难听清输出的音频信息；
另一方面，现有技术手机与汽车之间的连接多为蓝牙、RFID(射频识别)和WiFi等技术，这样用户在车外时与汽车进行直接语音交互时又存在以下问题：
1)定位精度问题，现有技术的连接方式的测距精度普遍较低，难以进行精确定位以区分用户是在车内还是车外，也就难以进行语音交互的准确设计；
2)安全性问题，现有技术的连接方式容易受到中继攻击的问题，影响汽车的使用安全。
目前，超宽带(Ultra Wide Band，UWB)技术是一种无线载波通信技术，它不采用正弦载波，而是利用纳秒级的非正弦波窄脉冲传输数据。UWB技术解决了困扰传统无线通信技术多年的有关传播方面的重大难题，具有对信道衰落不敏感、发射信号功率谱密度低、截获率低、系统复杂度低、能提供数厘米的定位精度等优点。
图1揭示了根据本发明一实施例的基于位置的语音交互方法流程图，如图1所示，本发明提出的基于位置的语音交互方法，通过检测用户的动作开启声音采集流程，具体包括以下步骤：
S11、响应于检测到电子设备与目标车辆之间的相对位置关系满足预设条件，显示包含有语音图标的交互界面，并生成动作检测指令，所述动作检测指令指示检测用户的动作，所述目标车辆设置至少一个外部扬声器；
S12、响应于检测到所述用户的预设开启动作，生成声音采集指令，所述声音采集指令指示采集所述用户的声音信号；
S13、执行所述声音采集指令，以采集所述声音信号并发送至所述目标车辆相对应的车载控制器；以及
S14、经由所述至少一个外部扬声器输出所采集的声音信号。
在图1所示的实施例中，步骤S11和步骤S12的执行主体可以为电子设备。
所述电子设备可以是手机、平板、智能眼镜、智能头盔或者智能手表等可穿戴智能设备。
在图1所述的实施例中，步骤S13的执行主体可以为电子设备或电子设备的关联部件。
所述电子设备的关联部件可以是耳机、耳麦、话筒等与所述电子设备建立有线或无线连接的外接语音采集部件。
如图1所述的实施例中，所述步骤S14的执行主体可以为目标车辆。由此，在车辆预设距离范围内，能够根据用户操作利用电子设备或其关联部件采集用户语音并通过车载外部扬声器进行输出播放，从而实现基于车辆的扩声系统，使车辆具备对外语音播放等功能。
下面以电子设备是手机为例，详细说明如图1所示的实施例中，本发明提出的基于位置的语音交互方法的具体步骤。
S11、响应于检测到电子设备与目标车辆之间的相对位置关系满足预设条件，显示包含有语音图标的交互界面，并生成动作检测指令，所述动作检测指令指示检测用户的动作，所述目标车辆设置至少一个外部扬声器。
本实施例中，手机与目标车辆之间的相对位置关系可以是基于蓝牙定位、超宽带UWB等近场通信方式而测定的。优选地，手机与目标车辆之间的相对位置关系是基于超宽带UWB方式而测定的。
相对于RFID和蓝牙技术，UWB测量距离的精确度更高，可以达到厘米级。此外，UWB技术具有极高的时间分辨率。UWB的抗干扰性能很强。蓝牙与WiFi使用频段为2.4GHz，易受外界干扰(例如，微波炉也是2.4GHz)。UWB常用频段为是6.5G和8G，不易受外界干扰。而且UWB的时间戳极为精确，可以做到抗多径干扰。安全性方面，UWB具备中继攻击保护能力，这主要得益于其精确计算实际物理距离的特性，如果判断飞行时间过长，直接判定基于UWB技术的手机端不在有效范围内，即便放大信号干扰，也无法与汽车进行通信与语音交互，攻击者无法对其进行欺骗。
当检测到手机与目标车辆之间的相对位置关系满足预设条件，手机的显示屏显示包含有第一图标的交互界面，并生成动作检测指令，所述动作检测指令指示检测用户的动作。
所述相对位置关系，是指电子设备(例如手机)与目标车辆之间的相对距离关系和相对角度关系。上述相对位置关系需要满足一定的预设条件，才会显示交互界面，开始进一步的语音交互流程。优选地，所述预设条件为电子设备处于目标车辆之外。
在一些实施例中，预设条件可以为手机在车外且离车20米。在另一些实施例 中，预设条件可以为手机在车外且在目标车辆车身左侧180°范围内。由此可以根据电子设备与目标车辆之间的相对位置关系来确定用户的语音交互需求。
图2揭示了根据本发明一实施例的第一图标示意图，如图2所示的第一图标为麦克风的小图标。
在进行相对位置关系的检测之前，手机与目标车辆需要进行身份鉴权匹配，同样可以通过超宽带UWB方式进行鉴别，此时手机等远端设备相当于数字钥匙。
手机与目标车辆设备在进行UWB鉴别时，目标车辆的车载控制器可以处于未唤醒状态，从而一定程度上节约了目标车辆的能源消耗。
当检测到手机与目标车辆之间的相对位置关系满足预设条件时，可以对目标车辆的车载控制器进行唤醒。
手机生成唤醒指令以发送至所述目标车辆，所述唤醒指令指示唤醒所述目标车辆相对应的车载控制器。
更进一步的，当手机检测到所述手机与目标车辆之间的相对位置关系不满足预设条件时，隐藏所述交互界面和/或停止检测所述用户的动作，此时认为手机已经远离目标车辆一定距离范围，停止语音交互，从而一方面减少了车辆的耗电情况，另一方面提升了用户的使用体验。
S12、响应于检测到所述用户的预设开启动作，生成声音采集指令，所述声音采集指令指示采集所述用户的声音信号。
手机检测所述用户的动作是否满足预设开启动作，如果用户的动作满足预设开启动作，则生成声音采集指令，采集用户的声音信号。
可选的，用户的预设开启动作，包括以下的任意一种：
所述用户针对所述语音图标的第一预设操作；以及
所述用户针对所述电子设备的第二预设操作。
可选的，第一预设操作包括但不限于：单击、双击、长按、重压、圈选、滑动或拖动等操作。
可选的，第二预设操作包括但不限于：摇一摇、晃一晃等操作。
所述声音采集指令指示手机或耳机、耳麦、话筒等电子设备的关联部件采集所述用户的声音信号。由此，一方面可以根据用户的动作来确定用户的语音交互需求，另一方面可以无需准备专用的麦克风，并且进一步解放了用户的双手，使得用户可以在查阅电子设备上呈现的内容的同时进行清晰的语音输入，提高了用户体验。
S13、执行所述声音采集指令，以采集所述声音信号并发送至所述目标车辆相对应的车载控制器。
手机或耳机话筒等电子设备的关联部件执行声音采集指令，采集用户的声音信号并经由电子设备(例如手机)发送至目标车辆。进一步地，手机或耳机话筒等电子设备的关联部件执行声音采集指令时，可以采集用户的声音信号并实时经 由电子设备(例如手机)发送至目标车辆的车载控制器。
所采集的声音信号，可以通过无线通讯方式发送至目标车辆。
本实施例中，采用无线通讯方式将采集的声音信号发送至目标车辆时，并不仅限于UWB通道，也可以通过蓝牙、WIFI、4G/5G移动通信网络等其他无线数据传输方式。
电子设备或电子设备的关联部件执行声音采集指令时，语音图标在所述交互界面上被显示为第二图标。
图3揭示了根据本发明一实施例的第二图标示意图，如图3所示的第二图标为麦克风的大图标。
更进一步的，手机检测所述用户的动作是否满足预设断开动作，如果用户的动作满足预设断开动作，停止采集所述用户的所述声音信号，从而用户可以通过动作操作开始或停止采集声音信号。
可选的，用户的预设断开动作，同样包括以下的任意一种：
所述用户针对所述语音图标的第一预设操作；以及
所述用户针对所述电子设备的第二预设操作。
可选的，第一预设操作包括但不限于：单击、双击、长按、重压、圈选、滑动或拖动等操作。
可选的，第二预设操作包括但不限于：摇一摇、晃一晃等操作。
显然，预设开始动作和预设断开动作可以设置为对应的操作，例如单击一次开始采集，再单击一次停止采集。
预设开始动作和预设断开动作也可以设置为不对应的操作，例如单击一次开始采集，双击一次停止采集或者单击一次开始采集，摇一摇手机停止采集。
需要进一步说明的，当用户的动作满足预设断开动作，停止采集所述用户的所述声音信号之后，如果再次满足预设开启动作，同样可以再次开始采集声音信号，语音交互流程并没有停止。
S14、经由所述至少一个外部扬声器输出所采集的声音信号。
车辆设置的多个外部扬声器输出所采集的用户的声音信号。
进一步地，车辆设置的多个外部扬声器可以实时地输出所采集的用户的声音信号，也可以是延时(例如延迟10min)、定时(例如设定为18：00)或基于预设条件的触发(例如检测到车门被轻敲或被打开)而输出所采集的用户的声音信号。
更进一步的，由于本发明采用UWB技术可以精确获得相对位置关系，因此，当车辆设置有多个外部扬声器时，可以基于精确的相对位置关系，选择指定的目标扬声器进行声音播放，从而满足车辆的立体声环绕播放效果。
例如，当车辆对称分布设置有4个外部扬声器时，可以选择距离用户较近的2个目标扬声器进行播放，当用户改变位置时绕到车辆另一侧时，此时可以选择 离用户更近的另外2个目标扬声器进行播放。又例如，当车辆对称分布设置有4个外部扬声器时，可以选择用户所处角度范围内对应的外部扬声器为目标扬声器进行播放，例如用户处于车身左前90°范围内，则确定左前外部扬声器为目标扬声器。进一步地，还可以根据用户的朝向来确定目标扬声器，例如用户的朝向为朝南，则选择朝南的外部扬声器为目标扬声器。具体地，可以根据电子设备的移动轨迹朝向来确定用户的朝向。
由此，可以根据用户与车辆的相对位置关系，选择相对应的外部扬声器输出用户声音信息，从而实现扩声方向的精准控制。
下面结合图2和图3，以电子设备是手机为例，说明如图1所示的实施例的基于位置的语音交互方法流程。
当手机与目标车辆之间的相对位置关系满足预设条件时，手机界面上显示如图2所示的麦克风小图标，供用户进行选择；
当用户点击手机界面上的麦克风小图标时，手机检测到用户的点击动作，生成声音采集指令，手机话筒或者耳机开始实时采集用户的声音，手机界面上显示如图3所述的麦克风大图标，用于指示正在进行语音采集输入；
手机将采集的用户声音信号发送至目标车辆，目标车辆的外部扬声器输出所采集的用户声音信号。
当用户再次点击手机界面的麦克风大图标时，停止采集用户的声音，手机界面显示为如图2所示的麦克风小图标，并关闭无线麦克风功能，但是仍可接收用户再次点击手机界面上的麦克风小图标，从而再次打开无线麦克风功能，开始采集用户的声音。由此，实现精准地语音采集和语音播放。
当手机与目标车辆之间的相对位置关系不再满足预设条件时，例如手机进入车内或者离开一定距离，隐藏所述交互界面和/或停止检测所述用户的动作，手机界面的麦克风图标隐藏消失，从而一方面减少了手机/车辆的耗电情况，另一方面提升了用户的使用体验。
图4揭示了根据本发明另一实施例的基于位置的语音交互方法流程图，如图4所示，本发明提出的基于位置的语音交互方法，通过检测用户声音，判断用户面部与手机的距离，在用户面部贴近电子设备时将所采集的声音发送至目标车辆，开启与目标车辆的语音交互，具体包括以下步骤：
S21、响应于检测到所述电子设备与目标车辆之间的相对位置关系满足第一位置条件，显示包含有语音图标的交互界面，并生成声音采集指令，所述声音采集指令指示采集用户的声音信号，所述目标车辆设置至少一个外部扬声器；
S22、基于所采集的声音信号，确定所述用户的面部与所述电子设备的相对位置距离；
S23、响应于确定所述用户的面部与所述电子设备的相对位置距离满足第二位置条件，生成发送指令，所述发送指令指示发送所采集的声音信号至所述目标 车辆相对应的车载控制器；以及
S24、经由所述至少一个外部扬声器输出所采集的声音信号。
在图4所示的实施例中，步骤S21-步骤S23的执行主体为电子设备和/或电子设备的关联部件。
所述电子设备可以是手机、平板、智能眼镜、智能头盔或者智能手表等可穿戴智能设备。
所述电子设备的关联部件可以是耳机、耳麦、话筒等与所述电子设备建立有线或无线连接的外接语音采集部件。
在图4所述的实施例中，所述步骤S24的执行主体为目标车辆。
下面以电子设备是手机为例，详细说明如图4所示的实施例中，本发明提出的基于位置的语音交互方法的具体步骤。
S21、响应于检测到所述电子设备与目标车辆之间的相对位置关系满足第一位置条件，显示包含有语音图标的交互界面，并生成声音采集指令，所述声音采集指令指示采集用户的声音信号，所述目标车辆设置至少一个外部扬声器；
本实施例中，手机与目标车辆之间的相对位置关系是基于超宽带UWB方式而测定的。
当检测到手机与目标车辆之间的相对位置关系满足第一位置条件，手机的显示屏显示包含有第一图标的交互界面，并开始实时采集用户的声音信号。
本实施例中，可以采用手机或者与手机连接的耳机采集用户的声音信号。
所采集的用户声音信号，一方面作为音频输入信号，另一个方面，作为对用户面部与手机的相对位置距离进行声场定位的判断信号。
当与手机连接的耳机所采集的用户声音信号作为音频输入时，手机麦克风采集用户声音信号对用户的面部与手机的相对位置距离进行声场定位。
在一些实施例中，第一位置条件可以为手机在车外且离车20米。
第一图标可以是如图2所示的麦克风的小图标。
在进行相对位置关系的检测之前，手机与目标车辆需要进行身份鉴权匹配，同样可以通过超宽带UWB方式进行鉴别，此时手机等远端设备相当于数字钥匙。
手机与目标车辆设备在进行UWB鉴别时，目标车辆的车载控制器可以处于未唤醒状态，从而一定程度上节约了目标车辆的能源消耗。
当检测到手机与目标车辆之间的相对位置关系满足第一位置条件，可以对目标车辆的车载控制器进行唤醒。
手机生成唤醒指令以发送至所述目标车辆，所述唤醒指令指示唤醒所述目标车辆相对应的车载控制器。
更进一步的，当手机检测到所述手机与目标车辆之间的相对位置关系不满足第一位置条件，隐藏所述交互界面和/或停止采集所述用户的声音信号，此时认为手机已经远离目标车辆一定距离范围，停止语音交互。
S22、基于所采集的声音信号，确定所述用户的面部与所述电子设备的相对位置距离。
手机根据所采集的声音信号，计算用户面部与手机的相对位置距离，当用户面部与手机的相对位置距离满足第二位置条件时，认为用户需要开启无线麦克风功能，通过手机与汽车进行语音交互。
在一些实施例中，第二位置条件可以为面部与手机的相对位置距离为5厘米。
显然，第二位置条件是可以预先设置的。
S23、响应于确定所述用户的面部与所述电子设备的相对位置距离满足第二位置条件，生成发送指令，所述发送指令指示发送所采集的声音信号至所述目标车辆相对应的车载控制器。
当手机检测到所述用户的面部与手机的相对位置距离满足第二位置条件，生成发送指令，将采集的用户声音信号并发送至目标车辆。
所采集的声音信号，可以通过无线通讯方式发送至目标车辆。
本实施例中，采用无线通讯方式将采集的声音信号发送至目标车辆时，并不仅限于UWB通道，也可以通过蓝牙、WIFI、4G/5G移动通信网络等其他无线数据传输方式。
在所述用户的面部与所述电子设备的相对位置距离满足第二位置条件时，所述语音图标在所述交互界面上显示为第二图标。
第二图标可以是如图3所示的麦克风的大图标。
更进一步的，当手机检测到所述用户的面部与所述手机的相对位置距离不满足第二位置条件，停止发送所采集的声音信号。
更进一步的，当手机在停止发送所采集的声音信号之后，如果再次检测到所述用户的面部与所述手机的相对位置距离满足第二位置条件，则再次生成发送指令，发送所采集的声音信号。
显然，本实施例的技术方案，主动采集用户声音并通过用户面部与电子设备的相对位置距离进行发送，相比于如图1所示的实施例，减少了用户对交互界面的操作，促进了无感语音交互，提升了用户体验，降低了对电子设备的能耗。
S24、经由所述至少一个外部扬声器输出所采集的声音信号。
车辆设置的多个外部扬声器实时输出所采集的用户的声音信号。
更进一步的，由于本发明采用UWB技术可以精确获得相对位置关系，因此，当车辆设置有多个外部扬声器时，可以基于精确的相对位置关系，选择指定的目标扬声器进行声音播放，从而满足车辆的立体声环绕播放效果。
例如，当车辆对称分布设置有4个外部扬声器时，可以选择距离用户较近的2个目标扬声器进行播放，当用户改变位置时绕到车辆另一侧时，此时可以选择离用户更近的另外2个目标扬声器进行播放。
尽管为使解释简单化将上述方法图示并描述为一系列动作，但是应理解并领 会，这些方法不受动作的次序所限，因为根据一个或多个实施例，一些动作可按不同次序发生和/或与来自本文中图示和描述或本文中未图示和描述但本领域技术人员可以理解的其他动作并发地发生。
图5揭示了根据本发明一实施例的基于位置的语音交互系统的原理框图，如图5所示的实施例中，本发明提出的基于位置的语音交互系统，包括电子设备510以及设置于目标车辆上的车载控制器520和至少一个外部扬声器530，其中，
