具体实施方式
为使本发明的目的、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的详细说明。应当理解，此处所描述的具体实施方式仅仅用以解释本发明，并不限定本发明的保护范围。
图1中示出了一个实施例中的车辆智能解锁的方法的流程示意图，如图1所示，该实施例中的方法包括步骤：
步骤S101：在整车处于闭锁状态时，控制设置在车辆的各天线发送低频信号；
步骤S102：接收车辆智能钥匙在接收到各所述天线的低频信号时返回的第一响应信号，所述第一响应信号包括所述车辆智能钥匙检测到的各天线的信号强度；
步骤S103：根据所述第一响应信号中的各天线的信号强度确定所述车辆智能钥匙所处的区域；
步骤S104：当车辆智能钥匙处于迎宾区域时，对所述车辆智能钥匙进行智能钥匙预认证，并在预认证通过后，发出提示信息；
步骤S105：在车辆智能钥匙处于靠近解锁区域时，对所述车辆智能钥匙 进行智能钥匙认证，在认证通过后控制整车解锁，并在整车解锁后、车辆的任意一个车门处于打开状态时，控制各所述天线停止发送低频信号。
根据如上所述的本发明实施例的方案，其通过在整车处于闭锁状态时，控制设置在车辆的各天线发送低频信号，并基于车辆智能钥匙返回的第一响应信号中的各天线的信号强度以确定车辆智能钥匙所处的区域，在车辆智能钥匙处于迎宾区域时，对车辆智能钥匙进行预认证并在预认证通过后发出提示信息，以对车辆智能钥匙的持有用户进行提醒，在车辆智能钥匙处于靠近解锁区域时，再对车辆智能钥匙执行完整的认证过程，并在认证成功后控制整车解锁，其不仅实现车辆的智能解锁，通过迎宾区域和靠近解锁区域的划分，分别执行预认证提醒和具体的认证过程，预认证成功后的点亮迎宾灯和认证成功后的车辆解锁，极大地提高了车辆用户的使用体验，且由于已经事先智能解锁，可以快速打开车门，提高了便捷性。
其中，在上述控制整车解锁时，可以同时控制车辆灯进行灯光指示，以对车辆用户进行提醒。基于上述方式进行车辆的智能解锁之后，还可以进一步实现车辆离开时的车辆智能闭锁。
因此，图2中示出了另一个实施例中的车辆智能解锁的方法的流程示意图，该实施例中，主要是对离开时对车辆闭锁的过程进行说明。
如图2所示，该实施例中的方法包括步骤：
步骤S201：在整车处于解锁且退电状态、车门均处于关闭状态时，控制设置在车辆的各所述天线发送低频信号；
步骤S202：接收车辆智能钥匙在接收到各所述天线的低频信号时返回的第二响应信号，所述第二响应信号包括所述车辆智能钥匙检测到的各天线的信号强度；
步骤S203：根据所述第二响应信号中的各天线的信号强度确定所述车辆智能钥匙是否处于闭锁离开区域，若是，控制整车闭锁。
从而，不仅可以实现车辆智能钥匙靠近车门时的智能解锁，还可以实现车辆智能钥匙离开时的智能闭锁。避免了因车门没闭锁(例如忘记按闭锁按键(或电容传感器))就离开带来的安全隐患。其中，在上述控制整车闭锁时， 也可以同时控制车辆灯进行灯光指示，以对车辆用户进行提醒。
在上述两个实施例中，上述设置在车辆的各天线的具体位置，可以结合实际需要进行设定。在一个具体应用示例中，上述各天线可以包括：设置在车内门饰板的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为车内门饰板天线)、设置在中控扶手箱的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为中控扶手箱天线)、以及设置在汽车后保的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为汽车后保天线)。
基于上述设置的三个天线，通过车内门饰板天线，可以有效检测出车辆智能钥匙距离车辆车门的位置，而结合中控扶手箱天线和汽车后保天线，可以有效排除车辆智能钥匙在车内的情况，避免了车辆智能钥匙在车辆内的误解锁或者误闭锁的情况。
据此，在上述判定车辆智能钥匙所处的区域时，一个具体应用示例中的方式可以是如下所述：
当车内门饰板天线的信号强度大于或等于第一车内门饰板信号强度、中控扶手箱天线的信号强度小于或者等于中控扶手箱天线信号强度阈值、汽车后保天线的信号强度小于或者等于汽车后保天线信号强度阈值，确定车辆智能钥匙处于迎宾区域，所述第一车内门饰板信号强度为距离所述车内门饰板天线第一预定距离处的车内门饰板天线的信号强度，所述中控扶手箱天线信号强度阈值为所述中控扶手箱天线在车内的信号的信号强度阈值，所述汽车后保天线信号强度阈值为所述汽车后保天线在车内的信号的信号强度阈值；
当车内门饰板天线的信号强度大于或等于第二车内门饰板信号强度、中控扶手箱天线的信号强度小于或者等于所述中控扶手箱天线信号强度阈值、汽车后保天线的信号强度小于或者等于所述汽车后保天线信号强度阈值，确定车辆智能钥匙处于靠近解锁区域，所述第二车内门饰板信号强度为距离所述车内门饰板天线第二预定距离处的车内门饰板天线的信号强度，所述第二预定距离小于所述第一预定距离；
当车内门饰板天线的信号强度小于或等于第三车内门饰板信号强度、中 控扶手箱天线发出的信号强度小于或者等于所述中控扶手箱天线信号强度阈值、汽车后保天线发出的信号强度小于或者等于所述汽车后保天线信号强度阈值，确定车辆智能钥匙处于闭锁离开区域，所述第三车内门饰板信号强度为距离所述车内门饰板天线第三预定距离处的车内门饰板天线的信号强度，所述中控扶手箱天线信号强度阈值为所述中控扶手箱天线在车内的信号的信号强度阈值，所述汽车后保天线信号强度阈值为所述汽车后保天线在车内的信号的信号强度阈值。
上述第一预定距离、第二预定距离、第三预定距离，可以结合实际需要来实现，例如，上述第一预定距离为3米，所述第二预定距离为1米，所述第三预定距离为2米，以具有较好的乘车体验的舒适性和安全性。
图3中示出了一个具体示例中的天线设置位置的示意图，图3所示中，结合车身的俯视图和侧视图进行说明，如图3所示，天线包括有：设置在车内门饰板的车内门饰板天线A1、设置在中控扶手箱的中控扶手箱天线A2、以及设置在汽车后保或者说汽车后保附近的汽车后保天线A3。通过车内门饰板天线A1、中控扶手箱天线A2、汽车后保天线A3分别发送信号，可以形成各天线的磁场，通过标定各天线磁场的强度，并对各天线磁场的强度进行组合，从而可以划分或者限定出迎宾区域、靠近解锁区域和离开闭锁区域，当然也可以限定出车内区域。
图4中示出了基于图3所示的示例中的各天线确定的信号强度范围的示意图，如图4所示，任意一个天线，以其自身为中心，向外辐射发出低频信号，从而形成以各天线为中心的磁场，各天线产生的磁场可能会产生重叠。
图5中示出了基于图3所示的示例中车内门饰板天线A1的第一预定距离内的信号强度范围的示意图，将车内门饰板天线A1形成的磁场的信号强度记为H(A1)，以第一预定距离为3米为例，将车内门饰板A1在3米处的磁场的信号强度记为H(3米，A1)，那么，车内门饰板天线A1的第一预定距离内的信号强度范围可以表示为：H(A1)≥H(3米，A1)。
中控扶手箱天线A2产生的磁场的信号强度可以进行标定，以限定其磁场限定在车内，此外，由于钣金金属能够把磁场挡住，从而，也可以确保中控 扶手箱天线A2产生的磁场也可以限定在车内，具体将中控扶手箱天线A2产生的磁场限定在车内的方式可以采用各种可能的方式，本发明实施例方式不做限定。因此，由于中控扶手箱天线A2产生的磁场在车内，如前所述，中控扶手箱天线A2可用以有效排除车辆智能钥匙在车内的情况，因此，可以将中控扶手箱天线A2产生的磁场的信号强度记为H(A2)，控扶手箱天线A2在车内的信号的信号强度阈值可记为H(中控，A2)。
类似地，对于汽车后保天线A3，其可以用以有效排除车辆智能钥匙在汽车后保(车辆行李箱或者车辆后尾箱)的情况，可以将汽车后保天线A3产生的磁场的信号强度记为H(A3)，汽车后保天线A3在车内的信号的信号强度阈值可记为H(车内行李箱，A3)。
基于图3至图5所示的示例，以第一预定距离为3米，第二预定距离为1米，第三预定距离为2米为例，对车内门饰板天线A1、中控扶手箱天线A2、以及汽车后保天线A3产生的磁场的信号强度进行组合，对迎宾区域、靠近解锁区域和离开闭锁区域可以做以下设定：
迎宾区域的信号强度的范围为：H(A1)≥H(3米，A1)and H(A2)≤H(中控，A2)and H(A3)≤H(车内行李箱，A3)，即当车内门饰板天线A1的信号强度H(A1)大于或等于第一车内门饰板信号强度H(3米，A1)、中控扶手箱天线A2的信号强度H(A2)小于或者等于中控扶手箱天线信号强度阈值H(中控，A2)、汽车后保天线A3的信号强度H(A3)小于或者等于汽车后保天线信号强度阈值H(车内行李箱，A3)，可以确定车辆智能钥匙处于迎宾区域。结合图3至图5所示的示例确定的迎宾区域的示意图如图6中的灰色区域所示。
靠近解锁区域的信号强度的范围为：H(A1)≥H(1米，A1)and H(A2)≤H(中控，A2)and H(A3)≤(车内行李箱，A3)，即当车内门饰板天线A1的信号强度H(A1)大于或等于第二车内门饰板信号强度H(1米，A1)、中控扶手箱天线A2的信号强度H(A2)小于或者等于中控扶手箱天线信号强度阈值H(中控，A2)、汽车后保天线A3的信号强度H(A3)小于或者等于汽车后保天线信号强度阈值H(车内行李箱，A3)，可以确定车辆智能钥匙 处于靠近解锁区域。
离开闭锁区域的信号强度的范围为：H(A1)≤H(2米，A1)and H(A2)≤H(中控，A2)and H(A3)≤(车内行李箱，A3)，即当车内门饰板天线A1的信号强度H(A1)小于或等于第三车内门饰板信号强度H(2米，A1)、中控扶手箱天线A2的信号强度H(A2)小于或者等于中控扶手箱天线信号强度阈值H(中控，A2)、汽车后保天线A3的信号强度H(A3)小于或者等于汽车后保天线信号强度阈值H(车内行李箱，A3)，可以确定车辆智能钥匙处于离开闭锁区域。
可以理解的是，当中控扶手箱天线A2的信号强度H(A2)大于或者等于中控扶手箱天线信号强度阈值H(中控，A2)、汽车后保天线A3的信号强度H(A3)大于或者等于汽车后保天线信号强度阈值H(车内行李箱，A3)，可以确定车辆智能钥匙是处于车内区域。
基于如上所述的车辆区域划分方式，在具体应用过程中，在整车处于闭锁状态时，车辆的智能进入控制器控制设置在车辆的各天线发送低频信号，以检测车辆智能钥匙的靠近。
图7示出了一个具体应用示例中的靠近解锁的处理流程的示意图。如图7所示，当用户携带车辆智能钥匙进入上述迎宾区域(即距离车内门饰板天线的距离在3米以内时)，智能进入控制器检测到车辆智能钥匙进入了迎宾区域，智能进入控制器发送低频信号和车辆智能钥匙进行智能钥匙预认证，具体的预认证的过程，可以采用任何可能的认证方式进行。在一个具体示例中，为了提高反应速度，在进行智能钥匙预认证时，可以只对无线报文的报文头进行认证，具体的认证方式在此不再展开赘述。在预认证通过后，智能进入控制器可发出迎宾灯点亮指令给车身控制器，由车身控制器点亮迎宾灯，这里的迎宾灯可以是包括位置灯、水坑灯等车辆灯。
在迎宾灯点亮后，智能进入控制器进行靠近解锁区域的钥匙寻找。当用户携带车辆智能钥匙进入靠近解锁区域，智能进入控制器对车辆智能钥匙进行认证，具体的认证过程可以任用任何的无线认证的方式进行，并在认证通过后，发送解锁整车的指令给车身控制器，由车身控制器进行整车解锁。在 控制整车解锁的同时，还可以同时进行灯光指示，以提醒用户车辆已解锁，这里的灯光指示可以是采用车辆灯闪烁等方式。本领域技术人员可以理解，还可以采用其他的灯光方式或者结合声音提醒的方式来进行提醒。
在车辆解锁后，用户可打开车门进行上车，当检测到车辆的任意一个车门处于打开状态时，可控制各天线停止发送低频信号，以节省能源。
图8示出了一个具体应用示例中的离开闭锁的处理流程的示意图。如图8所示，当用户将车辆停稳后，将整车退电，车辆门关好，携带车辆智能钥匙离开。当智能进入控制器检测到整车处于解锁且退电状态、车门均处于关闭状态时，会开始进行离开闭锁的车辆智能钥匙寻找，控制各上述天线发送低频信号。
当用户携带车辆智能钥匙离开车辆2米、且车内没有钥匙时，智能进入控制器基于车辆智能钥匙返回的第二响应信号，检测到车辆智能钥匙处于上述闭锁离开区域，智能进入控制器发送整车闭锁指令给车身控制器，由车身控制器控制整车闭锁。在控制整车闭锁的同时，还可以同时进行灯光指示，以提醒用户车辆已闭锁，这里的灯光指示可以是采用车辆灯闪烁等方式。本领域技术人员可以理解，还可以采用其他的灯光方式或者结合声音提醒的方式来进行提醒。
基于与上述方法相同的思想，本发明实施例还提供一种车辆智能解锁的装置。图9中示出了一个实施例中的车辆智能解锁的装置的结构示意图。
如图9所示，该实施例中的车辆智能解锁的装置包括：
天线控制模块901，用于在整车处于闭锁状态时，控制设置在车辆的各天线发送低频信号，并在整车解锁后、车辆的任意一个车门处于打开状态时，控制各所述天线停止发送低频信号；
钥匙区域确定模块902，用于接收车辆智能钥匙在接收到各所述天线的低频信号时返回的第一响应信号，所述第一响应信号包括所述车辆智能钥匙检测到的各天线的信号强度；根据所述第一响应信号中的各天线的信号强度确定所述车辆智能钥匙所处的区域；
车辆控制模块903，用于在所述钥匙区域确定模块确定车辆智能钥匙处于迎宾区域时，对所述车辆智能钥匙进行智能钥匙预认证，并在预认证通过后，发出提示信息；在所述钥匙区域确定模块确定车辆智能钥匙处于靠近解锁区域时，对所述车辆智能钥匙进行智能钥匙认证，在认证通过后控制整车解锁。
根据如上所述的本发明实施例的方案，其通过在整车处于闭锁状态时，控制设置在车辆的各天线发送低频信号，并基于车辆智能钥匙返回的第一响应信号中的各天线的信号强度以确定车辆智能钥匙所处的区域，在车辆智能钥匙处于迎宾区域时，对车辆智能钥匙进行预认证并在预认证通过后发出提示信息，以对车辆智能钥匙的持有用户进行提醒，在车辆智能钥匙处于靠近解锁区域时，再对车辆智能钥匙执行完整的认证过程，并在认证成功后控制整车解锁，其不仅实现车辆的智能解锁，通过迎宾区域和靠近解锁区域的划分，分别执行预认证提醒和具体的认证过程，预认证成功后的点亮迎宾灯和认证成功后的车辆解锁，极大地提高了车辆用户的使用体验，且由于已经事先智能解锁，可以快速打开车门，提高了便捷性。
其中，在上述控制整车解锁时，可以同时控制车辆灯进行灯光指示，以对车辆用户进行提醒。基于上述方式进行车辆的智能解锁之后，还可以进一步实现车辆离开时的车辆智能闭锁。
据此，在一个具体应用示例中：
上述天线控制模块901，还用于在整车处于解锁且退电状态、车门均处于关闭状态时，控制设置在车辆的各所述天线发送低频信号；

上述车辆控制模块903，还用于在所述钥匙区域确定模块确定所述车辆智能钥匙处于闭锁离开区域，控制整车闭锁。
从而，不仅可以实现车辆智能钥匙靠近车门时的智能解锁，还可以实现车辆智能钥匙离开时的智能闭锁。避免了因车门没闭锁(例如忘记按闭锁按 键(或电容传感器))就离开带来的安全隐患。其中，在上述控制整车闭锁时，也可以同时控制车辆灯进行灯光指示，以对车辆用户进行提醒。
在上述两个实施例中，上述设置在车辆的各天线的具体位置，可以结合实际需要进行设定。在一个具体应用示例中，上述各天线可以包括：设置在车内门饰板的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为车内门饰板天线)、设置在中控扶手箱的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为中控扶手箱天线)、以及设置在汽车后保的天线(为便于与其他天线从名称上进行区分，本发明实施例中称之为汽车后保天线)。
基于上述设置的三个天线，通过车内门饰板天线，可以有效检测出车辆智能钥匙距离车辆车门的位置，而结合中控扶手箱天线和汽车后保天线，可以有效排除车辆智能钥匙在车内的情况，避免了车辆智能钥匙在车辆内的误解锁或者误闭锁的情况。
据此，上述钥匙区域确定模块902在上述判定车辆智能钥匙所处的区域时，一个具体应用示例中的方式可以是如下所述：
当车内门饰板天线的信号强度大于或等于第一车内门饰板信号强度、中控扶手箱天线的信号强度小于或者等于中控扶手箱天线信号强度阈值、汽车后保天线的信号强度小于或者等于汽车后保天线信号强度阈值，确定车辆智能钥匙处于迎宾区域，所述第一车内门饰板信号强度为距离所述车内门饰板天线第一预定距离处的车内门饰板天线的信号强度，所述中控扶手箱天线信号强度阈值为所述中控扶手箱天线在车内的信号的信号强度阈值，所述汽车后保天线信号强度阈值为所述汽车后保天线在车内的信号的信号强度阈值；

以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
