附图标记： 1智能手机、 2NFC标签 具体实施方式
以下结合附图与具体实施例进一步阐述本发明的优点。
参阅图 1， 本发明具有 FC (近场通信） 标签 2的智能手机 1 的结构示 意图。 本发明的智能手机 1包括了 NFG天线及发送单元。 其中所述的 NFG天 线是指使得智能手机 1具有 NFC功能的天线或基站， 目前的智能手机 1越来 越多地配置有该 NFC天线， 一般放置在智能手机 1的外壳后或直接集成在电 池板上。 而发送单元即为通过不同远距离传输的通信方式如 GSM传输、 蓝牙 传输、 W-LAN传输或近场通信等与外部设备通信的模块， 一般内置于智能手 机 1 内， 具有上述两部件的智能手机 1 中， NFC天线与发送单元通信连接， 发送单元便将从 NFC天线接收的信息发送给外部设备。 本发明中， 智能手机 1还包括了一 NFC标签， 与该智能手机 1 组装成一体， 即附着在智能手机 1 上或通过任何连接件将 NFC标签 2与智能手机 1连接， 使其成为智能手机 1 的一部分。该 NFG标签 2包含了一标识信息，存储在 MFC标签 2内。设置时， 可将 NFG标签 2靠近 NFC天线设置，使得 NFC标签 2与 NFC天线间以 NFC (近 场通信） 模式连接， NFC天线读取 NFG标签 2的标识信息便完成表示信息从 NFG标签 2发送至 NFC天线的过程， 接收到该标识信息后， NFC天线便转发 至发送单元， 使得发送单元发出的信号中包含该标识信息， 由此， 标识信息 便成为智能手机 1发送单元发出的信号的辨识特征及加密信息， 由外部设备 通过远距离传输方式接收并验证， 来达到加密发送单元发送的信号的技术效 由于现有技术中部分智能手机 1也存在着使用 NFC标签 2的方式，但使 用方法却与本发明大相径庭。 本领域技术人员可知的是， 常见使用 NFC标签 2的方式为： 在手机外部设有一 NFG标签 2， 当智能手机 1的 NFC天线扫过 该 MFC标签 2时， NFC标签 2将记录下此时的智能手机 1的设置或软件的设 置情况， 此后， 当智能手机 1再次扫过该 NFG标签 2时， 将根据记录的设置 自动切换至该设置。可知的是，本发明对 NFC标签 2的使用与现有技术中 NFG 标签 2的使用方法不同，将 NFC标签 2作为提供标识的媒介且内置于智能手 机 1 内， 使得使用者可通过智能手机 1将该 NFC标签 2随身携带。
上述所述的标识信息可包括 NFC标签 2的 I D号及加密信息。 即， NFC 天线与 NFC标签 2通信后，可获取置于手机内的 NFC标签 2的标识号及密码。 类似于个人电脑的物理地址， 独一无二且容易验证正确与否。 而密码则可以 是设置在使用于智能手机 1内的应用程序上，仅当使用者输入正确的密码时， 智能手机 1 才可向车辆发送控制信号。 更具体地， 该加密信息可以是以 AES 标准加密的密码。 当智能手机 1需要将重要数据与外部设备交换时， 便可利 用 AES标准对数据进行加密， 具体地， 智能手机 1 内还设有一数据加密存储 器， 对发送的数据以 AES标准加密。 本领域技术人员可知的是， 也可利用应 用程序代替该数据加密存储器来完成加密工作。
当然， 也可在 NFC标签 2内存储智能手机 1 的辨识码 （I ME I )， 作为与 NFC标签 2匹配的标准， 在验证 NFC标签 2的标识号的基础上， 还将核对手 机辨识码是否准确， 具体地， NFC标签 2存储匹配的手机的辨识码， 仅当智 能手机 1的辨识码与存储的手机辨识码一致时， 才可将 NFC标签 2激活， 优 选地进一步提高了安全性。
本发明实施例中， NFC标签 2可设于智能手机 1 内的以下位置： 将 NFC 标签 2黏贴在智能手机 1或其外壳上， 外露于智能手机 1， 方便使用者替换； 或集成在智能手机 1的壳体内， 例如黏贴在手机壳体的内表面上， 方便手机 生产商在制造过程中便将 NFC标签 2设置完成； 亦或是放置在智能手机 1的 蓄能部件例如电池板上， 靠近手机的 NFC天线， 防止手机无法识别 NFC标签 2的情况产生； 再或是集成于一可拆卸的保护外壳上， 目前使用者使用智能 手机 1的习惯中， 会采用一保护外壳罩在智能手机 1的外部， 因此， 利用该 保护外壳， 可将 NFG标签 2黏附在其上。
一优选实施例中， 考虑到其他使用者可能将一使用者的手机内的 NFG标 签 2取下获取 NFC标签 2的标识信息， 在 NFC标签 2上还设有断裂结构， 当 NFG标签 2需要被动取下时， 必须以该断裂结构为受力点取下， 导致该断裂 结构断裂， 破坏了 NFG标签 2， 取下后便无法二次使用， 在硬件上确保每一 NFC标签 2仅可对应一位使用者使用。
同样地， 为了增加 NFG标签 2的应用性， 标签上还设有开关， 可激活或 关闭标签， 当不使用标签时， 关闭该标签， 避免了其他 NFC天线靠近该标签 并读取标签内的标识信息的情况， 进一步确保了安全性能。
又一实施例中， NFC标签上包含智能手机 1的设备制造商的标签， 举例 来说， 当 NFG标签 2依附在智能手机 1上时可将智能手机的设备制造商的标 签 （如 i phone、 Samsung, nok i a) 等设计在 NFC标签上， 从而不影响智能手 机整体的结构。
上述任一实施例中的智能手机 1在向外部设备发送信号时， 可利用 NFG 标签 2的标识信息对信号进行加密。 作为第三方媒介， NFC标签 2集成在手 机内后携带方便， 使用者可自由控制其开启或关闭。使用时无需再向第三方 团体索要标识码的请求， 相比与现有技术的加密方式简单很多。
本发明还公开了一种具有上述任一实施例中的智能手机 1的车辆控制系 统， 参阅图 2， 为该系统的示意图。 该系统中， 上述实施例中所述的外部设 备即为车辆， 为了建立车辆与智能手机 1的通信关系， 车辆内设有电子控制 单元， 其放置在车辆内， 该电子控制单元接收智能手机 1发来的信号， 并根 据该信号内包含的指令控制车辆。 该车辆控制系统的实施例中， 智能手机 1 与电子控制单元间的通信仍以常见的 GSM、 蓝牙、 W- LAN等通信信道建立。
一实施例中， 电子控制单元内包括有一收发模块， 用于接收所述智能手 机 1发来的信号并发送信号至智能手机 1 (若需要）。但与现有技术不同的是， 由于智能手机 1具有 NFG标签 2， 其发送的信号具有该 NFC标签 2特有的标 识信息， 而收发模块内可存储正确连接的 NFG标签 2的标识信息， 以验证电 子控制单元是否与正确的智能手机 1连接， 使得电子控制单元与智能手机 1 间的通信不再为开放性网络，外界无法轻易接入上述两者间，提高了安全性。 这一技术效果在车辆控制系统中尤为重要， 若车辆与外部控制终端（智能手 机 1 ) 间的通信是开放式的， 相当于所有可与车辆的控制单元连接的控制终 端均可向其发送例如解锁、 闭锁、 启动等指令， 给使用者带来相当大的经济 损失。 因此， 亟需实施例中采用简单的方式对控制终端与车辆电子控制单元 间的通信进行加密的手段来确保车辆仅受使用者使用正确的控制终端控制。
为了帮助电子控制单元验证智能手机 1 发送的信号中附加的 NFC标签 2 的标识信息是否与正确的 NFG标签 2的标识信息一致， 电子控制单元接收到 智能手机 1发来的信号后， 向智能手机 1发送质询请求。 本实施例中所述质 询请求， 意指电子控制单元接收到信号及标识信息后， 向发来此标识信息的 终端 （手机） 二次确认其是否为可执行控制操作的正确的终端， 该质询过程 将在下文详述。根据该质询请求， NFC标签 2将发送一响应信息至发送单元， 发送单元接收到该响应信息后，将其转发至电子控制单元，以验证标识信息。
因此， 优选的实施例中， 智能手机 1 内还设有接收单元， 用于中继该质 询请求。 具体地， 当电子控制单元发送质询请求至接收单元时， 接收单元将 中继质询请求至该 NFC标签 2, 根据该质询请求， NFG标签 2发送一响应信 息至发送单元， 其中响应信息对应于质询请求， "回答 "质询请求的质询， 以帮助电子控制单元验证标识信息是否正确无误。 本实施例中， 接收单元与 发送单元可集成为一模块， 发送与接收的过程互不影响， 保证该质询请求的 发送、接收并验证过程在整个搡作程序中占用的时间短， 不会带来因为质询 及响应的过程而导致控制的延时。
参阅图 3， 车辆控制系统还包括一 NFC基站， 其设于车辆上。 如前所述 的， 现有技术中， 当手机的蓄能部件的能量耗尽时， 使用者便无法再利用手 机发送信号至车辆来对车辆控制。 因此， 在车辆上对应已配置有 NFC标签 2 的智能手机 1， NFC基站可直接与该 NFC标签 2进行通信。 优选的实施例中， 可将 NFG基站设置在门把手、 B2~柱或挡风玻璃内， 方便使用者将 NFG标签 2 与 NFC基站非接触式连接。在 NFG标签 2建立与 NFC基站的通信连接后， NFG 标签 2发出的信号通过 NFC基站发送至电子控制单元内。 具体地， 当使用者 将带有 NFC标签 2的智能手机 1保持在带有 NFC基站的门把手上时， 门把手 上的 NFG基站识别到带有 NFC标签 2的智能手机 1的接近，并激发 NFC通信； 随后， NFC标签 2通过 NFC发送标识信息至 NFC基站； NFC基站接收标识信 息并进行审核。如果标识信息中包含的 NFG标签 2的标识号已存储在 MFC基 站内， NFC基站通过车辆总线将 NFC标签 2的标识号和一份关于解锁的查询 发送给电子控制单元， 用于车辆进入； 针对车辆进入的电子控制单元接收标 识号和查询后， 电子控制单元将它们识別为有效， 并执行车辆的解锁并为使 用者生成一份确认信息 （例如 LED灯发出闪光起或闪烁器闪光）。
上述实施例中， 当电子控制单元接收到标识号和查询后， 也可对标识号 和查询进行质询和响应的搡作， 来确保接收到的控制信号是由正确的 NFG标 签 2发来的。 更具体地说来， NFC基站通过车辆总线从电子控制单元接收质 询和标识号， 并通过 NFC将它们发送给 NFG标签 2 ; MFC标签 2接收质询后， 形成一个响应， 并通过 NFC将响应发送给 NFC基站； NFC基站通过 NFC接收 应答， 通过车辆总线将响应和标识号一起发送给电子控制单元以验证。
具有上述实施例的配置后， 当手机电池电量用完后， 使用者依然可使用 配有 NFG标签 2的手机来进行解锁、 开锁的搡作。 相比于现有技术， 在任何 时间都可对车辆进行操作。 且本领域技术人员可知的是， 每次 NFC标签 2靠 近 NFC基站与其通信时， NFG基站将自动提供充电给 NFC标签 2， 使用者将 不需要担心 NFG标签 2无法使用。
另一优选实施例中， NFC标签 2设有一低频无线电接口， 其由 MFC天线 供电， 也可直接由智能手机 1供电。 具备该低频无线电接口后， 低频无线电 接口的使用类似于现有的无线电码， 可用于定位具有该 NFC标签 2的智能手 机 1， 帮助使用者了解：
① NFG标签 2或是智能手机 1位于车辆内还是车辆外；
② NFG标签 2或是智能手机 1与车辆之间的距离；
③ NFG标签 2或是智能手机 1位于车辆的哪一侧。
即使用者通过该 MFC标签 2的低频无线电接口可了解并确定 NFC标签 2 相对于车辆的位置。 该低频无线电接口可由外置的电池供电， 亦或是可充电 的电池充电， 该充电电池由 NFC天线定期充电， 又或是 NFC天线直接为低频 无线电接口供电。 由此， 与现有的无线电码类似地， 带有本实施例中的 NFC 标签 2的智能手机 1可实现车辆功能 "被动式汽车进入"和 "被动式行走"。 这样，现代的无线电码的所有功能都可以通过带有低频无线电接口的 NFG标 签 2的智能手机 1来实现。 随着智能手机 1 应用程序 （APP) 的功能的日益强大， 使用者也可安装 或利用相关的软件， 在获取电子控制单元发来的一确认信号后， 通过应用程 序获取信号中车辆状态信息， 并显示在智能手机 1上。 由此， 使用者不仅可 以控制车辆， 还可随时了解愛车的最新状况， 提前获得故障、 告警信息， 在 驾乘的安全性上也具有了响应的提高。
如前所述的质询与响应的过程， 另一实施例中可采用其他配置来确保电 子控制单元与带有正确的 NFC标签 2的智能手机 1通信。 具体来说， 在正确 有效的 NFG标签 2第一次（或使用者指定的某一次）通过智能手机 1与电子 控制单元通信连接时，电子控制单元存储 NFC标签 2的标识信息及加密密码。 当 NFC智能手机 1再次与电子控制单元连接时， 电子控制单元将存储的 NFC 标签 2的标识信息及加密密码与此次接收到的 NFG标签 2的表示信息及加密 密码进行核对， 仅当一致时， 才可根据该信号控制车辆， 即形成一完整的辨 识有效的 NFC标签 2的过程。 相比于质询与响应的过程， 整个过程应用于电 子控制单元内， 所需时间缩短， 但第一次通信连接时的 NFC标签 2是否正确 有效却无法判断， 仍然可知的， 该判断辨识的程序提高了车辆与手机间的通 信安全。
参阅图 4, 为本发明车辆控制系统的系统操作示意图。 本发明中的控制 系统的控制方法包括以下步骤：
智能手机 1通过内置于智能手机 1的 NFG天线与已附着的 NFC标签 2通 信连接， 获取 MFC标签 2的标识信息；
NFC天线将获取的标识信息转发至发送单元， 使得发送单元发出的信号 包含该标识信息；
发送单元与电子控制单元以现有的通信信道通信连接， 将包含 标识信息的信号发送至电子控制单元。
上述控制方法为智能手机通过 NFC天线、 NFC标签将发送的信号进行加 密及处理的简要步骤， 通过上述方法， 电子控制单元接收到的信号即包含了 NFC标签添加的标识信息。 同时， 另一实施例中的控制方法中， 包含以下步骤：
为了验证标识信息是否正确， 电子标签在接收到信号后发送一质询请求 至智能手机 1 ;
智能手机 1接收到该质询请求后， 中继该请求至 NFG标签 2 ;
NFC标签 2根据该质询请求， 发送一响应信息至智能手机 1；
智能手机 1 中继该响应信息至电子控制单元；
电子控制单元验证所述响应信息， 若正确， 则根据所述指令执行搡作。 如上文所述， 智能手机的搡作可建立在手机应用 APP的基础上， 因此使 用者在上述实施例的步骤实施前， 可通过相关的 APP发送一查询请求至电子 控制单元， 用以说明 NFG标签 I D号并请求电子控制单元解锁。 电子控制单 元根据查询请求比对已存储的正确的标签 I D号进行检查， 比对正确后才会 发出上述步骤中的质询请求， 帮助使用者可手动开启质询及响应的过程。
当然， 如上所述， NFC标签 2发出的响应信息可包含标签 I D号， 以使 得已存储了正确 NFC标签 2的标签 I D号的电子控制单元进行匹配验证。
以下以智能手机 1要求解锁为实例详细说明质询及响应过程：
A. 使用者通过智能手机 1要求对车辆解锁。例如，这可通过操作智能手 机 1应用程序 （APP) 或菜单命令实现；
B. 智能手机 1通过通信信道发送一个查询， 用于使信号包含标签 I D号 并要求解锁；
C. 车辆的收发模块识別上述查询并检查标签 I D号。如果标签 I D号被查 询到， 通过车辆总线将标签 I D号和查询进一步传送给电子控制单元；
D. 电子控制单元接收标签 I D号和查询， 形成一个质询请求， 然后将质 询与标签 I D号一起发送给收发模块；
E. 收发模块通过车辆总线接收标签 I D号和质询， 并通过通信信道发送 出去；
F. 智能手机 1接收到标签 I D号和质询， 并将标签 I D号识别为已知；
G. 智能手机 1 启动与 NFC标签 2之间的 NFG通信并将质询发送给 NFG 标签 2 ;
H. NFG标签 2接收到质询，形成一个响应信息并通过 NFC将响应发送给 智能手机 1 ;
I . 智能手机 1通过 NFG接收响应， 然后将响应与标签 I D号一起通过通 信信道发送；
丄 收发模块通过通信信道接收标签 I D 号和响应信息， 并识别标签 I D 号为已知， 再通过车辆将标签 I D号和响应发送给电子控制单元；
K. 电子控制单元接收标签 I D号和响应，其审核标签 I D号和响应，并识 别为有效，根据信号指令执行车辆的解锁并通过车辆总线向收发模块发送一 份带有标签 I D号的确认信息；
L. 收发模块通过车辆总线接收标签 I D号和确认信息， 并通过通信信道 继续传送给智能手机 1 ;
M. 智能手机 1接收标签 I D号和确认信息， 并最终给使用者提供一份关 于成功解锁的反馈信息 （例如可通过振动、 声音或智能手机 1弹出窗口来实 现）。
本领域技术人员可知的是， 为了完成上述流程， 需要满足以下条件：
① 车辆处于智能手机 1的通信有效范围内；
② NFC标签 2的加密密码保存在车辆存储的标签 I D号内以成功解锁。 如上述实施例所述的， 虽然智能手机 1 内附有一 NFG标签 2， 但并不影 响外部 NFG标签 2与智能手机 1的正常通信及 NFG标签 2误与外部其他 NFG 基站通信。 具体地， NFG标签 2若位于其他 NFC基站的读取区中， 通常其他 NFC基站的识别器将识别 NFC标签 2是否为该读取的 NFC标签 2, 同样地， 智能手机 1 内的 NFC天线也同样会辨识外部与集成的 NFC标签 2。
上述实施例中所提及的， 智能手机 1 的应用程序 （APP) 已应用广泛， 使用者可通过 APP来实现智能手机 1上的使用者引导和过程控制，甚至通过 APP建立手机与车辆间的通信关系。
采用上述技术方案后， 通过 NFC标签提供给智能手机标识信息， 并随手 机的控制信号共同发送便起到了加密的作用， 车辆或其他外部设备将验证该 标识信息。 由于 NFG标签的标识信息存储于标签内， 且 NFC天线与 NFC标签 通信时已经获取了 NFG标签的标识号， 不需要联系第三方机构。 另外， 当智 能手机电池耗尽时，使用者可将 NFG标签与设有 NFC基站的车辆直接通信来 进行控制， 保证在任意时段均可搡作。
应当注意的是， 本发明的实施例有较佳的实施性， 且并非对本发明作任 何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变 更或修饰为等同的有效实施例， 但凡未脱离本发明技术方案的内容， 依据本 本发明技术方案的范围内。
