附图说明

具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
在相关技术中，一些车辆的智能钥匙依靠射频(Radio Frequency，RF)数据(例如，433.92MHZ或315MHZ)和低频(Low frequency，LF)数据(例如，125KHZ)来进行定位。也就是，通过车载的LF天线发射LF数据，智能钥匙接收到LF数据后，通过RF发射天线回复至车辆的RF接收装置，完成智能钥匙所处位置的场强值，即接收的信号强度指示(Received Signal Strength Indication，RSSI)值的信息传递，从而实现智能钥匙的定位。这种方案中，由于采用LF信号进行轮询的方式，要实现车辆的主动式的无钥匙进入功能，则必须以牺牲车辆的静态功耗为代价，存在车辆一段时间停放后亏电的风险。发明人想到，可以将蓝牙方式作为对车钥匙进行轮询的方式，LF信号用于钥匙定位。这样，既规避了LF持续轮询的高功耗问题，又避免了蓝牙定位不精确的问题。
图1是一示例性实施例提供的无钥匙进入系统的结构框图。如图1所示，无钥匙进入系统100可以包括车钥匙10、蓝牙模块20、LF信号发射模块30和车身控制器(Body Control Module，BCM)40。
图2是一示例性实施例提供的无钥匙进入系统的控制方法的流程图。如图2所示， 该控制方法可以包括以下步骤：
步骤S11，蓝牙模块向车钥匙发送蓝牙信号广播。
步骤S12，在车钥匙基于蓝牙信号广播与蓝牙模块建立蓝牙连接的情况下，LF信号发射模块发射LF信号。
步骤S13，车钥匙将接收到的LF信号中的信号强度信息传输至BCM。
步骤S14，BCM根据LF信号中的信号强度信息对车钥匙进行定位，并根据定位确定车钥匙所在区域。
步骤S15，BCM根据车钥匙所在区域控制车辆的车门解锁或闭锁。
蓝牙模块可以在车辆出厂之后一直向外发送蓝牙信号广播来寻找车钥匙。当车钥匙与车辆距离较近时(例如，20米)，能够与蓝牙模块建立蓝牙连接。若车钥匙已与蓝牙模块建立蓝牙连接，则说明车钥匙已经在车辆附近了，已经能够接收到LF信号。此时，BCM可以控制LF信号以一定的周期发射模块发射LF信号(轮询)。LF信号发射模块可以包括多个LF天线。LF天线例如可以设置在车辆两侧和后备门处。
LF信号中的信号强度信息是指示接收LF信号的位置处的RSSI值信息。根据多个LF信号中的信号强度信息，能够用相关算法计算出接收LF信号的位置的定位信息。计算的具体方法为本领域技术人员所公知，此处不再详细描述。
BCM根据车钥匙的定位信息和预先存储的车门解锁/闭锁的控制策略，就能够实施无钥匙进入功能。
通过上述技术方案，车辆中的蓝牙模块向外发送蓝牙信号广播，在车钥匙与蓝牙模块建立蓝牙连接的情况下，LF信号发射模块发射LF信号。BCM根据LF信号中的信号强度信息对车钥匙进行定位，从而进行车门的解锁或闭锁。与相关技术中的发射LF信号进行轮询的方案相比，本方案中采用蓝牙的方式进行轮询来与车钥匙通信连接，节省了车辆的功耗，减小了车辆长期停放后亏电的风险。并且，通过蓝牙对车钥匙进行轮询，所受的干扰较小，可靠性高。
图3是另一示例性实施例提供的无钥匙进入系统的控制方法的流程图。如图3所示，在图2的基础上，车钥匙将接收到的LF信号中的信号强度信息传输至BCM的步骤(步骤S13)可以包括以下步骤：
步骤S131，车钥匙将接收到的LF信号中的信号强度信息通过蓝牙的方式发送给蓝牙模块。
步骤S132，蓝牙模块将LF信号中的信号强度信息转发给BCM。
也就是，用于为车钥匙定位的LF信号中的信号强度信息是通过蓝牙的方式而不是通过RF的方式发送给车辆的。蓝牙模块可以通过局域互联网络(Local Interconnect Network，LIN)或CAN线与BCM连接。BCM通过计算确定车钥匙的当前位置，并最终确定是否执行车门解锁或闭锁的动作。
该实施例中，车辆和车钥匙均无需设置RF信号收发模块，并且通过蓝牙发送信号强度信息，所受的干扰较小，车钥匙定位的可靠性高。
由于LF信号发射相比蓝牙需要更大的功耗，因此，在确定不需要应用无钥匙进入功能(包括无钥匙离开)时，可以控制停止发射LF信号。在又一实施例中，在图2或图3的基础上，在BCM根据车钥匙所在区域控制车辆的车门解锁或闭锁的步骤(步骤S15)之后，该方法还可以包括：若车辆进入上电状态、设防状态和睡眠状态中的任意一种状态，则LF信号发射模块停止发射LF信号。
若车辆进入上电状态(电源为ON)，则可以认为驾驶员正在控制车辆，此时没有必要应用无钥匙进入功能；若车辆进入设防状态和睡眠状态，则说明车辆已经下电且执行了闭锁的操作，不需要重复闭锁，并且，可以设置为在车辆处于唤醒状态下才可以执行解锁操作。即，无钥匙进入时，若已建立蓝牙通信连接，则先唤醒车辆再确定是否解锁，即解锁必须有车辆唤醒的前提条件。其中，设防状态为车辆防盗器的设防状态。
该实施例中，能够在识别不需要应用无钥匙进入功能，或者通过设置(唤醒状态下才可以执行解锁操作)，减少了LF信号的发射，从而减小了车辆的功耗。
车辆的无钥匙进入功能的闭锁模式通常可以分为主动模式和被动模式。在主动模式中不需要用户额外以接触的方式触发专用开关来解锁/闭锁，在被动模式中，除了需要满足主动模式中的解锁/闭锁条件之外，还需要用户额外以接触的方式触发专用开关，才能最终实现解锁/闭锁。在又一实施例中，该方法还可以包括：BCM确定无钥匙进入系统当前的闭锁模式。
在该实施例中，在图2或图3的基础上，BCM根据车钥匙所在区域控制车辆的车门解锁或闭锁的步骤(步骤S15)可以包括：BCM根据车钥匙所在区域和所确定的闭锁模式，控制车辆的车门解锁或闭锁。
用户可以通过在车辆、终端等设备的交互界面上选择无钥匙进入功能的闭锁模式为主动模式或被动模式。在主动模式和被动模式中，判断驾驶员进入和离开具有预先设定 的区域。图4是一示例性实施例提供的无钥匙进入系统的应用场景的示意图。如图4所示，在车辆两侧车门附近、后备门附近可以设置区域A，该区域A为被动进入区域或被动离开区域，被动进入区域和被动离开区域也可以为同一个区域。以车辆为中心的一个较大半径的圆形区域B为主动进入区域，在主动进入区域外，可以设置一个以车辆为中心的更大的圆环区域C为主动离开区域。其中，区域A最小，例如，每个区域A可以设置为半径为1m～1.5m的半圆；区域B较大，例如，区域B的半径可以为3m～5m；区域C在车辆的最外围，例如，可以设置为半径为5m～7m的圆环。
在驾驶员走近车辆时，可以通过以下实施例来应用无钥匙进入系统控制解锁车门。在该实施例中，在图2或图3的基础上，在车钥匙基于蓝牙信号广播与蓝牙模块建立蓝牙连接的情况下，LF信号发射模块发射LF信号的步骤(步骤S12)可以包括：在车钥匙基于蓝牙信号广播与蓝牙模块建立蓝牙连接的情况下，若车辆为睡眠状态，则BCM唤醒车辆；若车辆被唤醒，则LF信号发射模块发射LF信号。
也就是，如前所述的，在车辆处于唤醒状态下才发射LF信号，之后才有可能执行解锁操作。即，无钥匙进入时，若已建立蓝牙通信连接，则先唤醒车辆再确定是否解锁，即解锁必须有车辆唤醒的前提条件。这样，当车辆在设防状态和睡眠状态时，可以停止发射LF信号，减小功耗。
该实施例中，在车辆处于唤醒状态下，BCM根据车钥匙所在区域和所确定的闭锁模式，控制车辆的车门解锁或闭锁的步骤可以包括：若所确定的闭锁模式为主动模式，且车钥匙处于主动进入区域(区域B)，则BCM控制车辆的车门解锁；若所确定的闭锁模式为被动模式，车钥匙处于被动进入区域(区域A)，且满足被动进入触发条件，则BCM控制车辆的车门解锁。
其中，车钥匙处于主动进入区域(区域B)，加上车辆处于唤醒状态，说明驾驶员有意于启动车辆，此时若为主动模式，可以直接控制车门解锁；若为被动模式，还需判断是否满足被动进入触发条件，若满足，才能控制车门解锁。
用户可以通过触摸门把手，由车辆中的电容传感器输出触发信号，来满足被动进入触发条件。该被动进入触发条件为本领域技术人员公知，此处不再赘述。
在驾驶员离开车辆时，可以通过以下实施例来应用无钥匙进入系统控制闭锁车门。在该实施例中，在图2或图3的基础上，在车钥匙基于蓝牙信号广播与蓝牙模块建立蓝牙连接的情况下，LF信号发射模块发射LF信号的步骤(步骤S12)可以包括：在车钥 匙基于蓝牙信号广播与蓝牙模块建立蓝牙连接的情况下，若车辆由上电状态(电源为ON状态)切换为下电状态(电源为OFF状态)，则LF信号发射模块发射LF信号。
也就是，在车辆由上电状态切换为下电状态时，才发射LF信号，之后才有可能执行闭锁操作。即，无钥匙离开时，若已建立蓝牙通信连接(实际上一直在连接状态)，则先判定车辆由上电切换为下电，再确定是否闭锁，即闭锁必须有车辆切换为下电车辆的前提条件。这样，能够准确地判断驾驶员要离开的意图。
该实施例中，在车辆由上电切换为下电后，BCM根据车钥匙所在区域和所确定的闭锁模式，控制车辆的车门解锁或闭锁的步骤可以包括：若所确定的闭锁模式为主动模式，且车钥匙处于主动离开区域(区域C)，则BCM控制车辆的车门闭锁；若所确定的闭锁模式为被动模式，车钥匙处于被动离开区域(区域A)，且满足被动离开触发条件，则BCM控制车辆的车门闭锁。
其中，车钥匙处于主动离开区域(区域C)，加上车辆已由上电切换为下电，说明驾驶员有意于离开车辆，此时若为主动模式，可以直接控制车门闭锁；若为被动模式，还需判断是否满足被动离开触发条件，若满足，才能控制车门闭锁。
与被动进入触发条件相似地，用户可以通过触摸门把手，来满足被动离开触发条件。该被动离开触发条件为本领域技术人员公知，此处不再赘述。
另外，上述实施例中，也可以将车辆由上电状态切换为下电状态这一条件，替换为车辆由上电状态切换为下电状态和车门由开门状态切换到关门状态这两个条件。这样，能够更加准确地判断驾驶员要离开的意图。

可选地，LF信号发射模块30还用于若车辆进入上电状态、设防状态和睡眠状态中的任意一种状态，则停止发射LF信号。

并且，若所确定的闭锁模式为主动模式，且车钥匙10处于主动进入区域，则BCM 40用于控制车辆的车门解锁；若所确定的闭锁模式为被动模式，车钥匙10处于被动进入区域，且满足被动进入触发条件，则BCM 40用于控制车辆的车门解锁。
可选地，在车钥匙10基于蓝牙信号广播与蓝牙模块20建立蓝牙连接的情况下，若车辆由上电状态切换为下电状态，则LF信号发射模块30用于发射LF信号，
