具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
本申请中的车辆可以为广义概念上的车辆，可以是交通工具(如商用车、乘用车、摩托车、飞行车、火车等)，工业车辆(如：叉车、挂车、牵引车等)，工程车辆(如挖掘机、推土车、吊车等)，农用设备(如割草机、收割机等)，游乐设备，玩具车辆等，本申请实施例对车辆的类型不作具体限定。
图1是本申请实施例提供的一种车辆的示意性功能框图。如图1所示，车辆100可以包括感知系统120、显示装置130和计算平台150，其中，感知系统120可以包括感测关于车辆100周边的环境的信息的一种或多种传感器。例如，感知系统120可以包括定位系统，定位系统可以是全球定位系统(global positioning system，GPS)，也可以是北斗系统或者其他定位系统、惯性测量单元(inertial measurement unit，IMU)、激光雷达、毫米波雷达、超声雷达以及摄像装置中的一种或者多种。
车辆100的部分或所有功能可以由计算平台150控制。计算平台150可包括一个或多个处理器，例如处理器151至15n(n为正整数)，处理器是一种具有信号的处理能力的电路，在一种实现中，处理器可以是具有指令读取与运行能力的电路，例如中央处理单元(central processing unit，CPU)、微处理器、图形处理器(graphics processing unit，GPU)(可以理解为一种微处理器)、或数字信号处理器(digital signal processor，DSP)等；在另一种实现中，处理器可以通过硬件电路的逻辑关系实现一定功能，该硬件电路的逻辑关系是固定的或可以重构的，例如处理器为专用集成电路(application-specific integrated circuit，ASIC)或可编程逻辑器件(programmable logic device，PLD)实现的硬件电路，例如现场可编程 门阵列(field programmable gate array，FPGA)。在可重构的硬件电路中，处理器加载配置文档，实现硬件电路配置的过程，可以理解为处理器加载指令，以实现以上部分或全部单元的功能的过程。此外，还可以是针对人工智能设计的硬件电路，其可以理解为一种ASIC，例如神经网络处理单元(neural network processing unit，NPU)、张量处理单元(tensor processing unit，TPU)、深度学习处理单元(deep learning processing unit，DPU)等。此外，计算平台150还可以包括存储器，存储器用于存储指令，处理器151至15n中的部分或全部处理器可以调用存储器中的指令，执行指令，以实现相应的功能。
座舱内的显示装置130主要分为两类，第一类是车载显示屏；第二类是投影显示屏，例如抬头显示装置(head up display，HUD)。车载显示屏是一种物理显示屏，是车载信息娱乐系统的重要组成部分，座舱内可以设置有多块显示屏，如数字仪表显示屏，中控屏，副驾驶位上的乘客(也称为前排乘客)面前的显示屏，左侧后排乘客面前的显示屏以及右侧后排乘客面前的显示屏，甚至是车窗也可以作为显示屏进行显示。抬头显示，也称平视显示系统。主要用于在驾驶员前方的显示设备(例如挡风玻璃)上显示例如时速、导航等驾驶信息。以降低驾驶员视线转移时间，避免因驾驶员视线转移而导致的瞳孔变化，提升行驶安全性和舒适性。HUD例如包括组合型抬头显示(combiner-HUD，C-HUD)系统、风挡型抬头显示(windshield-HUD，W-HUD)系统、增强现实型抬头显示系统(augmented reality HUD，AR-HUD)。应理解，HUD也可以随着技术演进出现其他类型的系统，本申请对此不作限定。
图2是本申请实施例提供的一种示例性车辆座舱内显示屏分布的示意图。如图2所示，车辆的座舱内可以包括仪表屏201、显示屏202(或者，也可以称为中控屏)、显示屏203(或者，也可以称为副驾娱乐屏)、显示屏204(或者，也可以称为二排左侧区域的娱乐屏)以及显示屏205(或者，也可以称为二排右侧区域的娱乐屏)。
应理解，以下实施例中的图形用户界面(graphical user interface，GUI)是以图2所示的5座车辆为例进行说明的，本申请实施例并不限于此。例如，对于7座运动型多用途汽车(sport utility vehicle，SUV)，座舱内可以包括中控屏、副驾娱乐屏、二排左侧区域的娱乐屏、二排右侧区域的娱乐屏、三排左侧区域的娱乐屏以及三排右侧区域的娱乐屏。又如，对于客车而言，座舱内可以包括前排娱乐屏和后排娱乐屏；或者，座舱内可以包括驾驶区域的显示屏和乘客区域的娱乐屏。在一种实现中，乘客区域的娱乐屏也可以设置在座舱顶部。
在介绍本申请的技术方案之前，首先简单介绍本申请实施例中可能涉及的一些相关术语。
近场通信(near field communication，NFC)：使用了NFC技术的设备(例如智能手机、车机)可以在彼此靠近的情况下进行数据交换。
碰一碰流转：电子设备支持碰一碰流转能力时，只需碰一碰接触即可实现业务流转。例如，电子设备A与车辆B均支持碰一碰流转，电子设备A中运行导航时，只需碰一碰车辆B的中控屏，即可将电子设备A中的导航流转至中控屏中。
当前，通过NFC技术，车辆的座舱可以支持与电子设备进行碰一碰流转业务的能力，为用户带来了诸多便利。例如，具有鸿蒙操作系统的智能手机通过碰一碰将手机中的导航、音乐等业务流转至具有鸿蒙座舱操作系统的座舱中，使得座舱可以使用手机中的导航、音乐等业务。
应理解，车辆中可以部署有NFC芯片和NFC天线，以使得车辆可以具备NFC功能。在车辆使用NFC功能时，NFC天线可以用于接收或发射通信信号，NFC芯片用于通信信号的处理。
然而，有些车辆的座舱由于布局的原因，NFC天线部署在中控屏内部，由于中控屏边框较窄，导致NFC没有明显标志。因此，用户在使用智能手机碰一碰中控屏时，会不清楚NFC天线在中控屏的具体位置。本申请中将NFC天线在中控屏的具体位置称为NFC位置。
有鉴于此，本申请实施例提供一种NFC位置提示方法和设备。该技术方案可以在设备确定预设条件被满足的情况下，自动在显示屏中显示用于指示NFC位置的提示信息，以为用户提供指引，使得用户可以确定NFC天线的位置。
下文将结合图3-4介绍本申请实施例中在车辆的中控屏中显示NFC位置的技术方案。
示例性地，图3是本申请实施例提供的一组图形用户界面(graphical user interface，GUI)的示意图。其中，从图3中的(a)至(b)示出了一种中控屏自动显示NFC位置的过程。
参见图3中的(a)，车辆的中控屏可以显示显示界面300以及功能栏310。该显示界面300上包括用户账号登录信息301、蓝牙功能图标304、Wi-Fi功能图标303、蜂窝网络信号图标34、车载地图应用搜索框305、切换至显示车辆安装的所有应用程序的卡片306、切换至显示车载音乐应用的卡片307、车 辆剩余电量以及剩余行驶里程的显示卡片308、车辆360度(°)环影功能的显示卡片309。其中，车载地图应用搜索框305中可以包括用户设置的回家控件3051和去公司控件3052。
应理解，该显示界面300可以为中控屏的首页显示界面。
该功能栏310中至少可以包括切换至显示中控屏桌面的图标311、车辆内循环图标312、主驾座椅加热功能图标313，主驾区域空调温度显示图标314、副驾区域空调温度显示图标315、副驾座椅加热功能图标316以及音量设置图标317。
本申请实施例中，车辆可以和电子设备建立通信连接。
例如，车辆可以通过软总线与电子设备建立通信连接，当车辆检测到该电子设备与该车辆登录同一账号时，车辆的中控屏可以显示如图3中的(b)所示的GUI。
应理解，这种情况下，该电子设备需具备软总线模块，从而能够通过软总线与车辆建立通信连接。例如，电子设备安装有鸿蒙操作系统，车辆具有鸿蒙座舱操作系统。
应理解，本申请中，电子设备与车辆建立通信连接可以是通过蓝牙实现的。在另一些示例中，电子设备与车辆建立通信连接还可以通过其他无线、或有线等方式。例如，电子设备与车辆处于同一局域网下。
在另一个示例中，当车辆检测到该电子设备与该车辆登录同一账号时，车辆可以与电子设备建立通信连接，车辆进一步确定中控屏显示首页显示界面(或中控屏未显示其他应用程序的显示界面)，则车辆的中控屏可以显示如图3中的(b)所示的GUI。
在另一个示例中，当车辆检测到该电子设备与该车辆登录同一账号时，车辆可以与电子设备建立通信连接，车辆进一步确定车辆未开始导航的情况下，可以显示如图3中的(b)所示的GUI。
在另一个示例中，当车辆检测到该电子设备与该车辆登录同一账号时，车辆可以与电子设备建立通信连接，车辆进一步确定车辆处于P档且中控屏显示首页显示界面(或中控屏未显示其他应用程序的显示界面)，则车辆的中控屏可以显示如图3中的(b)所示的GUI。在另一些示例中，车辆每次检测到车辆从其他档位切换至P档时，可以触发中控屏显示如图3中的(b)所示的GUI。
在另一个示例中，当车辆检测到该电子设备与该车辆登录同一账号时，车辆可以与电子设备建立通信连接，车辆进一步确定车辆处于P档且车辆未开始导航的情况下，可以显示如图3中的(b)所示的GUI。在另一些示例中，车辆每次检测到车辆从其他档位切换至P档时，可以触发中控屏显示如图3中的(b)所示的GUI。
还应理解，在以上的示例中，当电子设备与车辆未登录同一账号时，电子设备需要在之前与车辆互相认证过。此时，电子设备与车辆也可以建立通信连接。
参见图3中的(b)，该GUI为中控屏提示NFC位置的显示界面320。该显示界面320中可以包括文本内容“使用华为手机碰一碰流转导航、音乐”，显示卡片325，手机图标323，功能按钮321和功能按钮322。
示例性地，该显示卡片325中可以包括功能栏的部分功能图标和NFC区域标识324。从而可以清晰地为用户呈现中控屏上NFC所在的位置，有利于用户进行精准地碰一碰流转业务。
示例性地，功能按钮321中可以显示文本内容“知道了(20)”，功能按钮322可以显示文本内容“了解更多”。当车辆检测到用户点击功能按钮321的操作之后，可以关闭该显示界面320。当车辆检测到用户点击功能按钮322的操作之后，可以弹出新的显示界面详细介绍该NFC的位置或功能。
在另一些示例中，该手机图标323还可以显示为动画效果。例如，该手机图标323可以从远离NFC区域标识324的位置逐渐靠近该NFC区域标识324，从而可以更加直观地指引用户使用手机进行碰一碰流转业务的操作。
在另一些示例中，车辆在需要显示NFC位置时，还可以在中控屏的底部与NFC天线位置相对应的地方显示NFC标识，而无需显示显示界面320，从而可以不影响用户对中控屏的使用。
应理解，当用户手机中开启导航时，用户使用手机触碰中控屏的NFC位置，则可以将该导航通传输至中控屏中显示。
图4是本申请实施例提供的另一组GUI的示意图。其中，从图4中的(a)至(b)示出了另一种中控屏自动显示NFC位置的过程。
应理解，图4中的(a)可以参见图3中的(a)的相关描述，为了简洁，此处不再赘述。
参见图4中的(b)，在功能栏310中可以显示NFC图标325。
示例性地，该NFC图标325可以位于车辆内循环图标312和主驾座椅加热功能图标313之间。
应理解，该NFC图标325还可以位于该功能栏310的其他位置处，本申请实施例对于限定。例如，当NFC天线设置于图标311与图标312之间时，该NFC图标325可以位于图标311与图标312之间。
或者，当该NFC天线设置于中控屏的其他位置处时，该NFC图标325可以在相应的地方显示。
在另一些示例中，该NFC图标325还可以是显示出闪烁效果，以更加明显地提示用户NFC的位置。
或者，功能栏310中NFC图标325所在的区域还可以是显示标识。例如，NFC图标325所在的区域可以高亮显示，或者彩色显示等。或者，该中控屏中还可以显示用于指向该NFC图标325所在的区域的箭头等。
图5是本申请实施例提供的一种显示NFC位置的方法的示意性流程图。如图5所示，该方法400可以包括步骤410至步骤420。
410，第一设备与第二设备建立通信连接。
示例性地，该第二设备可以是智能手机、平板、可穿戴设备等电子设备。该第一设备可以是车辆，还可以是平板、笔记本电脑、智能电视等大屏电子设备，本申请实施例不予限定。
本申请中，以第二设备为安装有鸿蒙操作系统的智能手机，第一设备为具有鸿蒙座舱操作系统的车辆为例进行说明。但这不应对本申请的应用场景造成任何限定，本申请实施例可以应用与任何需要提示NFC位置的场景下。
例如，当第一设备与第二设备均为具有鸿蒙操作系统时，可以通过软总线建立通信连接，从而第一设备与第二设备之间可以通过软总线传输数据。在另一些示例中，该第一设备与第二设备还可以是具有其他操作系统的设备，只需第一设备能够与第二设备建立软总线连接即可。
应理解，在第一设备与第二设备通过软总线建立通信连接时，在第一设备与第二设备登录同一个账号的情况或处于同一局域网下，连接过程可以自动进行。
可以理解的是，第一设备与第二设备还可以通过其他方式建立通信连接，如无线或有线等方式。
420，在确定第一设备显示第一显示界面的情况下，显示用于指示NFC位置的提示信息。
示例性地，参见图2，该第一显示界面可以是车辆的中控屏202的显示界面。例如，该第一显示界面可以是中控屏的首页显示界面，或者，该第一显示界面还可以是中控屏未显示其他应用程序的显示界面。
在车辆确定中控屏显示首页显示界面或未显示其他应用程序的显示界面的情况下，车辆可以控制中控屏显示用于指示NFC位置的提示信息。以提醒用户中控屏中NFC天线所在的位置。
示例性地，参见图3中的(b)，该提示信息可以是显示界面320。该提示信息可以是静态的画面，也可以是动态的画面。该提示信息还可以是指示手机靠近NFC位置的指引动画等。通过该提示信息，用户可以直观地确定控屏中NFC天线所在的位置。
在另一些示例中，参见图2，该第一显示界面还可以车辆的是其他显示屏203或显示屏204，本申请实施例不予限定。
在本申请的一个实施例中，车辆可以在与手机建立通信连接时，进一步确定中控屏是否显示在首页显示界面，当确定中控屏显示首页显示界面时，可以自动在中控屏中显示用于指示NFC位置的提示信息。从而用户可以根据该提示信息确定NFC天线在中控屏上的位置，有利于用户进行碰一碰流转业务的操作。
应理解，该步骤420中，车辆还可以在显示第一显示界面的情况下直接显示用于指示NFC位置的提示信息，而无需执行确定过程。
在一些实施例中，在步骤420之前，该方法还可以包括：
车辆确定车辆的档位处于驻车挡(P档)。
应理解，该车辆确定车辆处于P档的步骤也可以处于步骤420中，本申请实施例不予限定。
这样，当车辆确定车辆处于P档，且进一步确定中控屏显示首页的情况下，在中控屏中显示提醒用户NFC位置的提示信息，避免用户在车辆行车过程中执行该碰一碰操作，从而可以保证操作的安全性。
在另一些示例中，当车辆确定车辆处于空档(N档)，且进一步确定中控屏显示首页的情况下，在中控屏中显示提醒用户NFC位置的提示信息。
在一些实施例中，在步骤420之前，该方法还可以包括：
确定第二设备支持碰一碰流转能力。

示例性地，该导航类应用程序可以为华为地图、高德地图、百度地图等。当第一设备未运行该导航类应用程序时，可以在中控屏中显示用于指示NFC位置的提示信息。
应理解，第一设备未运行该导航类应用程序时，此时第一设备的中控屏可以显示其他应用程序的显示界面，也可以处于首页显示界面，本申请实施例不予限定。
这样，车辆未运行导航类应用程序时，可以确定用户此时可能没有导航需求，从而可以保证操作的安全性。
例如，参见图3中的(b)，该提示信息可以是显示界面320。又如，该提示信息还可以是指示手机靠近NFC位置的指引动画。或者，该提示信息还可以是NFC标识。
应理解，该步骤520中，车辆还可以在未运行导航类应用程序的情况下直接显示用于指示NFC位置的提示信息，而无需执行确定过程。
在本申请的一个实施例中，车辆可以在与手机建立通信连接时，进一步确定是否运行导航类应用程序，当确定未运行导航类应用程序时，可以自动在中控屏中显示用于指示NFC位置的提示信息。从而用户可以根据该提示信息确定NFC天线在中控屏上的位置，有利于用户进行碰一碰流转业务的操作。
在一些实施例中，在步骤520之前，该方法还可以包括：
车辆确定车辆的档位处于驻车挡(P档)。
应理解，该车辆确定车辆处于P档的步骤也可以处于步骤520中，本申请实施例不予限定。
这样，当车辆确定车辆处于P档，且进一步确定车辆未运行导航类应用程序的情况下，在中控屏中显示提醒用户NFC位置的提示信息，避免用户在车辆行车过程中执行该碰一碰操作，从而可以保证操作的安全性。
在一些情况下，用户需要经常切换车辆的档位，当车辆每次检测到档位切换到P档时，可以执行该步骤520。
在另一些示例中，当车辆确定车辆处于空档(N档)，且进一步确定车辆未运行导航类应用程序的情况下，在中控屏中显示提醒用户NFC位置的提示信息。
图7是本申请实施例提供的另一种显示NFC位置的方法的示意性流程图。如图7所示，该方法600可以包括步骤610至步骤660。
610，第一设备与第二设备建立通信连接。
应理解，该步骤610可以参见前文中步骤410的相关描述。为了简洁，此处不再赘述。
在一些示例中，当第一设备与第二设备通过软总线建立通信连接的情况下，第一设备的软总线还可以向座舱协同服务发送自组网成功的消息。
应理解，在第一设备与第二设备通过软总线建立连接后，可以理解为第一设备与第二设备自组网成功。此时，第一设备的软总线可以将该自组网成功的消息发送至座舱协同服务。
620，第一设备获取档位状态。
应理解，该档位状态指的是第一设备当前所处的档位，例如，P档、N档、前进挡(D档)、倒车档(R档)等。
示例性地，第一设备可以通过座舱子系统获取第一设备当前所处的档位。

640，第一设备获取第二设备的位置。
示例性地，第一设备中可以包括移动感知平台(mobile sensing development platform，MSDP)，该MSDP中至少可以包括多个传感器，例如超声波传感器，毫米波传感器等。MSDP通过该多个传感器可以确定第二设备与中控屏的位置，从而第一设备可以获取该第二设备的位置。
例如，该第二设备的位置可以是位于中控屏的左侧(主驾一侧)，或，该第二设备的位置可以是位于中控屏的右侧(副驾一侧)。
应理解，该步骤620至步骤640为可选步骤，在一些示例中，步骤620至步骤640也可以不执行。
650，第一设备确定是否显示用于指示NFC位置的提示信息。
应理解，第一设备可以根据步骤620至步骤640的相关内容确定是否在中控屏中显示用于指示NFC位置的提示信息。
在一些示例中，当第一设备确定档位处于P档，且第一设备未运行其他应用程序的情况下，可以确定显示用于指示NFC位置的提示信息。否则，可以确定不显示用于指示NFC位置的提示信息。
在另一些示例中，当第一设备确定档位处于P档，且第一设备未运行导航类应用程序的情况下，可以确定显示用于指示NFC位置的提示信息。否则，可以确定不显示用于指示NFC位置的提示信息。

660，在第一设备确定显示提示信息时，在中控屏上显示用于指示NFC位置的提示信息。
应理解，当第一设备确定显示提示信息时，在中控屏上显示用于指示NFC位置的提示信息。示例性地，参见图3中的(b)。
在另一些示例中，第一设备在确定显示提示信息，还可以根据第二设备的位置显示提示信息。例如，当座舱协同服务确定第二设备位于中控屏的左侧(主驾一侧)时，则提示信息中的第二设备的图标可以位于中控屏的左侧。
应理解，本申请对于步骤610至步骤660的执行顺序不予限定，在一些实施例中，该步骤610至步骤660的部分步骤也可以不执行，或者由其他步骤进行替代等等。例如，步骤620、630、640、650可以不执行。
在本申请的一个实施例中，第一设备和第二设备建立通信连接之后，第一设备可以获取相应的档位状态、活动状态、第二设备的位置等信息综合判断是否需要显示用于指示NFC位置的提示信息。在确定需要显示提示信息时，在中控屏中显示该提示信息，从而用户可以根据该提示信息确定NFC天线在中控屏上的位置，有利于用户进行碰一碰流转业务的操作。
下文将结合图8-9介绍本申请实施例中根据第一设备与第二设备之间的距离来显示NFC位置的技术方案。
图8是本申请实施例提供的另一种显示NFC位置的示意性流程图。如图8所示，该方法700可以包括步骤710至步骤740。
710，第一设备确定第一设备与第二设备之间的距离小于或等于第一预设距离。
应理解，第一设备与第二设备均为NFC设备，从而可以通过NFC技术确定两者之间的距离。在另一些示例中，还可以由第二设备确定第一设备与第二设备之间的距离。
第一设备与第二设备进行NFC通信时，例如，第一设备与第二设备之间的距离小于或等于第一预设距离时，第一设备的NFC天线会将中断on信号发送给系统软件。
本申请实施例对于该第一预设距离的具体取值不予限定，例如，该第一预设距离可以为5cm或3cm等。
720，第一设备显示用于指示NFC位置的提示信息。

本申请实施例对于该第一预设时长的具体取值不予限定。例如，该第一预设时长可以是2s或5s等。
示例性地，第一设备的系统软件在接收到中断on信号之后，或者在接收到中断on信号的第一预设时长后，可以控制中控屏显示上述用于指示NFC位置的提示信息。该系统软件可以是用于管理中控屏首页显示界面的系统软件。
730，第一设备确定第一设备与第二设备之间的距离大于第一预设距离。
当第一设备与第二设备之间的距离大于第一预设距离时，第一设备的NFC天线会将中断off信号发送给第一设备的系统软件。
740，移除用于指示NFC位置的提示信息。
之后，当第一设备的系统软件接收到off信号时，可以控制中控屏移除上述提示信息。
应理解，该提示信息还可以是背景透明的指引NFC位置的动画，从而可以不遮挡中控屏中显示的其他内容。当第一设备的系统软件接收到off信号时，控制中控屏移除上述提示信息，从而可以使得中控屏快速恢复原状。
应理解，在一些示例中，该步骤710和步骤720可以处于同一步骤中，该步骤730和步骤740可以处于同一步骤中，本申请实施例不予限定。在这种情况下，第一设备也可以直接在第一设备与第二设备之间的距离小于或等于第一预设距离时，直接显示用于指示NFC位置的提示信息，而无需执行判断过程。或者，第一设备也可以直接在第二设备与第一设备之间的距离大于第一预设距离时，直接移除用于指示NFC位置的提示信息，而无需执行判断过程。
在本申请的一个实施例中，当第一设备确定第一设备与第二设备之间的距离小于或等于第一预设距离时，可以显示用于指示NFC位置的提示信息；当第一设备确定第一设备与第二设备之间的大于第一预设距离时，可以移除用于指示NFC位置的提示信息。该技术方案可以使得第一设备能够根据两者之间的距离灵活显示或移除NFC位置的提示信息。
图9是本申请实施例提供的另一种显示NFC位置的示意性流程图。如图9所示，该方法800可以包括步骤810至步骤830。
810，第一设备确定第一设备与第二设备之间的距离小于或等于第一预设距离。
820，显示用于指示NFC位置的提示信息。
应理解，该步骤810-820可以参见前文中步骤710-720的相关描述，为了简洁，不再赘述。
在另一些示例中，该提示信息位于第一设备的中控屏的显示界面的最上层，也就是该提示信息可以直接接收并响应用户的操作。
830，在第二预设时长内，拦截到预设次数的点击操作的情况下，移除用于指示NFC位置的提示信息。
在用户或第二设备触碰第一设备的中控屏时，系统可以检测到点击操作，此时，由于中控屏最上层显示的是NFC的提示信息，系统可以拦截该点击操作。
应理解，该点击操作可是用户对第一设备的中控屏的点击操作，还可以是第二设备对中控屏的点击操作。通过设定预设次数的大小，可以防止第二设备误触中控屏的情况下，依然移除上述提示信息。
本申请实施例对于该第二预设时长的具体取值不予限定。
在本申请的一个实施例中，当第一设备确定第一设备与第二设备之间的距离小于或等于第一预设距离时，可以显示用于指示NFC位置的提示信息；在第二预设时长内，当第一设备拦截到预设次数的点击操作时，可以移除上述提示信息。该技术方案可以防止在用户或第二设备误触第一设备的中控屏时，依然移除NFC位置的提示信息。
应理解，上述图5至图9的技术方案可以相互结合使用，这种情况下的技术方案不应认为超出本申请的保护范围。
图10是本申请实施例提供的一种NFC位置提示方法的示意性流程图。如图10所示，该方法可以应用于第一设备，该方法可以包括步骤1010至步骤1020。
其中，第一设备与第二设备能够进行近场通信NFC。
1010，确定预设条件是否被满足，预设条件为第一条件或第二条件；其中，第一条件为第二设备与第一设备建立通信连接；第二条件为第一设备与第二设备之间的距离小于或等于第一预设距离。
应理解，第二设备与第一设备建立通信连接的过程可以参见前文中的相关描述。
应理解，第一设备与第二设备均为NFC设备，从而可以通过NFC技术确定两者之间的距离。第二条件中，当第二设备与第一设备之间的距离小于或等于第一预设距离时，第一设备的NFC天线会将中断on信号发送给系统软件，从而第一设备可以确定当前第二设备与第一设备之间的距离小于或等于第一预设距离。
本申请实施例对于该第一预设距离的具体取值不予限定。
1020，在确定预设条件被满足时，第一设备的显示屏中显示用于指示NFC位置的提示信息。
应理解，该用于指示NFC位置的提示信息可以是是静态的画面，也可以是动态的画面。该提示信息还可以是指示手机靠近NFC位置的指引动画等。或者，该提示信息还可以是NFC标识。通过该提示信息， 用户可以直观地确定显示屏中NFC天线所在的位置。
在一个示例性中，参见图3中的(b)，该提示信息可以是显示界面320。该提示信息可以包括NFC标识324，手机图标323，还可以包括文字等。
在另一个示例中，参见图4中的(b)，该提示信息可以为NFC标识325。
示例性地，当第一设备为车辆时，该显示屏可以是第一设备的中控屏，还可以是第一设备的其他显示屏。
在本申请的一个实施例中，第一设备可以在确定预设条件被满足时，在第一设备的显示屏中显示用于指示NFC位置的提示信息。该技术方案可以在预设条件下，自动在显示屏中显示用于指示NFC位置的提示信息，从而用户可以根据该提示信息确定NFC天线在中控屏上的位置，有利于用户进行碰一碰流转业务的操作。
在一些实施例中，在第一设备的显示屏中显示用于指示NFC位置的提示信息之前，该方法1000还可以包括：
确定第一设备的显示屏中显示首页显示界面或第一设备的显示屏中未显示其他应用程序的显示界面。
可以理解的是，第一设备的显示屏中显示首页显示界面可以理解为，显示屏显示主界面。例如，可以是开启第一设备的默认主界面，该主界面可以是一个显示界面，也可以是多个显示界面。第一设备的显示屏未显示其他应用程序的显示界面，可以理解为，第一设备中未运行其他应用程序，或者，其他应用程序运行在后台，其显示界面未显示在显示屏中。
示例性地，参见图3中的(a)，该显示界面300可以为中控屏的首页显示界面。
这样，当第一设备在确定显示屏显示主界面或未显示其他应用程序的显示界面的情况下，在显示屏中显示NFC位置的提示信息，从而可以不影响用户对于显示屏的正常使用。
在一些实施例中，在第一设备的显示屏中显示用于指示NFC位置的提示信息之前，该方法1000还可以包括：
确定第一设备中未运行导航类应用程序。
示例性地，该导航类应用程序可以是华为地图、高德地图等等。
这样，当第一设备未运行该导航类应用程序时，可以在中控屏中显示用于指示NFC位置的提示信息。车辆未运行导航类应用程序时，可以确定用户此时可能没有导航需求，从而可以保证操作的安全性，避免在导航的过程中在显示屏中显示该提示信息，危及行驶安全。
在一些实施例中，在第一设备的显示屏中显示用于指示NFC位置的提示信息之前，该方法1000还可以包括：
确定第一设备的档位处于第一档位。
示例性地，该第一档位可以是驻车档，还可以是空挡。
这样，当第一设备确定第一设备的档位处于第一档位时，显示上述提示信息。避免用户在车辆行驶过程中执行碰一碰操作，从而可以保证操作的安全性。
在一些实施例中，在第一设备的显示屏中显示用于指示NFC位置的提示信息之前，该方法1000还可以包括：
确定第二设备支持碰一碰流转能力。
示例性地，当第一设备与第二设备建立通信连接之后，第一设备与第二设备可以互相获取到对方的能力信息，从而第一设备可以确定第二设备是否支持碰一碰流转能力。或者，第二设备还可以通过蓝牙等方式将自己的能力信息发送给第一设备。
这样，第一设备在确定第二设备支持碰一碰流转能力时，在显示屏中显示用于指示NFC位置的提示信息，从而有利于用户执行碰一碰操作，避免在第二设备不支持碰一碰流转能力时，依然显示上述提示信息，为用户带来困扰。
在一些实施例中，提示信息中包括用于指示第二设备的标识，该方法1000还可以包括：
确定第二设备的位置；
第一设备的显示屏中显示用于指示NFC位置的提示信息，包括：第一设备根据第二设备的位置在显示屏中靠近第二设备的一侧显示标识。
应理解，第二设备可以根据超声波传感器、激光传感器等确定第二设备的位置。例如，确定第二设备位于显示屏的左侧(靠近主驾一侧)，或右侧(靠近副驾一侧)。
示例性地，参见图3中的(b)，该标识可以是手机图标323，当车辆确定手机位于中控屏的左侧(靠近主驾一侧)时，该提示信息中的手机图标323可以显示在中控屏的左侧。
这样，第一设备在确定了第二设备的位置后，可以根据该位置在显示屏中靠近第二设备的一侧显示用于指示第二设备的标识，从而可以精准地为用户提供指引。
在一些实施例中，在预设条件为第二条件的情况下，第一设备的显示屏中显示用于指示NFC位置的提示信息，包括：
在第一预设时长后，第一设备的显示屏中显示提示信息。
示例性地，该第一预设时长可以是2s或1s，本申请实施例对于该第一预设时长的具体取值不予限定。
这样，在第一设备确定第一设备与第二设备之间的距离小于或等于预设距离的情况下，又在第一预设时长后，第一设备在显示屏中显示上述提示信息，从而可以避免第二设备在误触第一设备的情况下，第二设备依然在显示屏中显示上述提示信息。
应理解，第一设备还可以直接显示该提示信息，而无需在第一预设时长之后。
在一些实施例中，提示信息位于显示屏的显示界面的最上层，该方法1000还可以包括：
在第二预设时长内，第一设备拦截对显示屏的点击操作；
当第一设备拦截到预设次数的点击操作时，第一设备移除提示信息。
示例性地，该点击可是用户对第一设备的显示屏的点击操作，还可以是第二设备对显示屏的点击操作。
在本申请的一个实施例中，该提示信息可以位于显示屏的显示界面的最上层，在用户或第二设备触碰第一设备的显示屏时，系统可以检测到点击操作，并拦截该点击操作。当第一设备拦截到预设次数的点击操作时，可以移除上述提示信息。该技术方案可以防止第二设备或用户误触显示屏的情况下，第一设备依然移除上述提示信息。
在一些实施例中，该方法1000还可以包括：
当确定第二设备与第一设备之间的距离大于第一预设距离时，第一设备移除提示信息。
这样，当第一设备确定第一设备与第二设备之间的距离大于第一预设距离时，可以移除用于指示NFC位置的提示信息，从而可以使得显示屏快速恢复原状，不影响用户对于显示屏的使用。
在一些实施例中，提示信息包括NFC标识。
在一些实施例中，第一档位为驻车档。
在一些实施例中，显示屏为第一设备的中控屏。
在另一些示例中，该显示屏还可以为第一设备的除中控屏之外的其他显示屏。
