本发明涉及车辆技术领域，特别涉及一种车辆的钥匙定位方法与车辆。
无钥匙进入系统通过低频-高频通讯形式，如通过ECU(Electronic Control Unit，电子控制单元)驱动车辆上多根不同位置搭载的天线发送特有频段的低频信号，钥匙在接收到该低频信号后返回对应的高频信号以及钥匙所处位置对应的场强信息，从而便于ECU根据钥匙返回的高频信号与场强信息确定钥匙的位置。在当前无钥匙进入系统进行钥匙定位的过程中，针对不同功能天线的分工和时序不同，如无钥匙进入功能、一键启动功能等天线被驱动的顺序不同。
但是，在不同功能中每个天线需要驱动至少一次，而在其中有一个或多个天线发生开路、短路或其他故障时，不同功能的钥匙定位均无法实现，从而影响车辆的正常启动、锁定等，使得车辆无法正常工作，影响用户驾驶体验。

需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本发明。
图1是本发明实施例提供的一种车辆的钥匙定位方法的步骤流程图，如图1所示，该方法可以包括：
步骤101、在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位的过程中，对驱动的所述天线进行故障诊断，所述第一驱动次序集合为所述车辆中任一功能对应的所述天线的驱动次序集合。
本发明实施例中，车辆通常配置多根天线以对钥匙进行准确定位，在定位过程中可以逐个驱动不同天线工作以确定钥匙是否位于该天线的定位范围内，其中，驱动天线指通过天线发送预定的低频数据或载波，针对车辆的不同功能，车辆的天线驱动次序集合不同，第一驱动次序集合可以指车辆中任一功能对应的天线的驱动次序集合，包括实现该功能所需的天线以及各天线的驱动次序，可选地，可以采用车辆的ECU对车辆上的天线进行驱动，本发 明实施例对车辆配置的天线数量以及不同功能对应的天线驱动次序集合不作具体限制。
图2是本发明实施例提供的一种车辆上天线配置示意图，如图2所示，车辆上配置有车顶天线①、车外主驾驶侧天线②、车外副驾驶侧天线③、车尾天线④，此时，车辆的功能与钥匙定位中天线驱动次序集合如下表1所示：
表1车辆的功能与天线驱动次序集合对应表
上表1中“数据”表示发送低频数据，“载波”表示将低频数据加载的载波的信号上发送，另外，上述功能与天线驱动次序集合的对应关系仅做示例，本领域技术人员可以根据实际条件与需求选择不同的天线驱动次序集合，本发明实施例对此不作具体限制。
本发明实施例中，可以在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位从而实现任一功能的过程中，对驱动的天线进行故障诊断，其中，包括对天线是否发生短路、开路等故障的诊断，可选地，可以在对每一天线进行驱动时对每一天线进行故障诊断，也可以仅对无法工作的天线进行诊断，可以采用ECU在对天线进行驱动时对该天线进行故障诊断，本发明实施例对此不作具体限制。
如，PKS启动功能对应第一驱动次序集合为“①(数据)→④(数据)→①②③④(载波)”，ECU在根据第一驱动次序集合对车辆上的天线进行驱动以定位钥匙的过程中，对驱动的天线“①→④→①②③④”进行故障诊断。
步骤102、在所述天线中存在故障天线的情况下，从所述第一驱动次序集合中去除所述故障天线的次序，获得第二驱动次序集合。
本发明实施例中，不同天线之间可以采用并连的连接方案，在天线中存在故障天线的情况下，可以在第一驱动次序集合中去除故障天线的次序，使得获得的第二驱动次序集合跳过故障天线，以获得第二驱动次序集合，从而避免故障天线影响车辆的正常工作情况。
如，在ECU根据第一驱动次序集合第车辆上的天线进行驱动的过程中，共诊断确定一个故障天线车尾天线④，因此，可以在第一驱动次序集合中去除④，获得第二驱动次序集合“①(数据)→①②③(载波)”。
步骤103、根据所述第二驱动次序集合，驱动所述车辆中除所述故障天线之外的其他天线工作以进行钥匙定位。
本发明实施例中，可以根据第二驱动次序集合驱动车辆中除故障天线以外的天线工作，从而保证车辆的功能基本实现，正常工作，提升驾驶体验。
如，ECU根据第二驱动次序集合“①(数据)→①②③(载波)”驱动天线，从而避免车辆由于追尾导致车尾天线④故障，导致车辆无法正常启动的问题。
本发明实施例中，在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位的同时，对天线进行故障诊断，从而在天线中存在故障天线的情况下，根据故障天线调整第一驱动次序集合，去除故障天线的次序，获得无需驱动故障天线的第二驱动次序集合，再根据第二驱动次序集合驱动车辆中除故障天线以外的其他天线以进行钥匙定位，使得在天线中存在故障天线的情况下，可以跳过故障天线对钥匙进行定位，保证车辆的正常启动、锁定等， 维持车辆的正常工作，且无需再对故障天线进行驱动，避免了无效驱动，提高了驱动效率，提升用户驾驶体验。
图3是本发明实施例提供的另一种车辆的钥匙定位方法的步骤流程图，如图3所示，该方法可以包括：
步骤201、在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位的过程中，对驱动的所述天线进行故障诊断，所述第一驱动次序集合为所述车辆中任一功能对应的所述天线的驱动次序集合。
本发明实施例中，在车辆根据第一驱动次序集合执行任一功能的天线驱动的工作模式中，进一步对驱动的天线进行故障检测，具体的，步骤201可对应参照前述步骤101的相关描述，为避免重复，在此不再赘述。
步骤202、在所述天线中存在所述故障天线，且所述故障天线的数量小于或等于预设故障数量的情况下，从所述第一驱动次序集合中去除所述故障天线的次序，获得第二驱动次序集合。
本发明实施例中，由于天线中可能存在一个以上的故障天线，为了保证车辆的功能正常实现，在确定天线中存在故障天线的情况下，还可以进一步确定故障天线的数量。预设故障数量可以根据保证车辆的功能正常实现的最少天线的数量，以及总的天线数量得到的，当故障天线的数量小于或等于预设故障数量时，可以认为余下的天线可以保证车辆的功能正常实现，因此，可以从第一驱动次序集合中去除故障天线的次序，获得第二驱动次序集合。
本发明实施例中，步骤202可对应参照前述步骤102的相关描述，为避免重复，在此不再赘述。
如，预设故障数量为2，在ECU根据第一驱动次序集合对车辆上的天线进行驱动的过程中，共诊断确定一个故障天线车尾天线④，则故障天线的数量小于预设故障数量，因此，可以在第一驱动次序集合中去除④的次序，获得第二驱动次序集合“①(数据)→①②③(载波)”。
步骤203、根据所述第二驱动次序集合，驱动所述车辆中除所述故障天线之外的其他天线工作以进行钥匙定位。
本发明实施例中，步骤203可对应参照前述步骤103的相关描述，为避免重复，在此不再赘述。
步骤204、在所述天线中存在所述故障天线，且所述故障天线的数量大于 所述预设故障数量的情况下，停止驱动所述天线。
本发明实施例中，在故障天线的数量大于预设故障数量的情况下，可以认为余下的天线不能保证车辆的功能正常实现，此时，可以停止驱动天线，避免无效的驱动造成浪费。
如，预设故障数量为2，在ECU根据第一驱动次序集合第车辆上的天线进行驱动的过程中，共诊断确定三个故障天线车尾天线①、②和④，则故障联系的数量大于预设故障数量，因此，可以停止驱动天线。
步骤205、对所述故障天线进行提示。
本发明实施例中，可以设置工作模式下的跛行模式，以区分存在以及不存在故障天线的情况，在工作模式下通过故障诊断确定不存在故障天线时则继续原工作模式，在存在故障天线的情况下进一步进入跛行模式，跛行模式具体包括在工作模式下根据第一驱动次序集合对天线驱动的流程完毕后，根据第二驱动次序集合跳过故障天线重新驱动。此时，可以在进入跛行模式的情况下对故障天线进行提示，可选地，可以提示故障天线的位置、数量，可以由ECU通过车载多媒体、仪表设备等信息提示，也可以通过车载无线通讯短信提示，本发明实施例对提示的内容和提示的方式不作具体限制。
本发明实施例中，在根据第一驱动次序集合驱动车辆中的天线以进行钥匙定位的同时，对天线进行故障诊断，从而在天线中存在故障天线的情况下，根据故障天线调整第一驱动次序集合，去除故障天线，获得无需驱动故障天线的第二驱动次序集合，再根据第二驱动次序集合驱动车辆中的天线以进行钥匙定位，使得在天线中存在故障天线的情况下，可以跳过故障天线对钥匙进行定位，保证车辆的正常启动、锁定等，维持车辆的正常工作，且无需再对故障天线进行驱动，提高了驱动效率，提升用户驾驶体验。
图4是本发明实施例提供的又一种车辆的钥匙定位方法的步骤流程图，如图4所示，该方法可以包括：
步骤301、在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位的过程中，对驱动的所述天线进行故障诊断，所述第一驱动次序集合为所述车辆中任一功能对应的所述天线的驱动次序集合。
步骤302、在所述天线中存在故障天线的情况下，从所述第一驱动次序集合中去除所述故障天线的次序，获得第二驱动次序集合。
步骤303、根据所述第二驱动次序集合，驱动所述车辆中除所述故障天线之外的其他天线工作以进行钥匙定位。
本发明实施例中，步骤301至步骤303可对应参照前述步骤101至步骤103的相关描述，为避免重复，在此不再赘述。
步骤304、在所述车辆进入闭锁状态的情况下，根据第三驱动次序集合在第一时间段内对所述天线进行轮询驱动，所述第三驱动次序集合为所述车辆的主动进入轮询功能对应的所述天线的驱动次序集合。
本发明实施例中，主动进入轮询功能指对车辆上的天线连续、不断的轮询驱动以使携带钥匙靠近车辆时车辆自动解锁，离开车辆时车辆自动闭锁的功能，在主动进入轮询功能中车辆的天线驱动次序集合为第三驱动次序集合。由于车辆进入闭锁状态后可能处于闲置状态，此时，连续不断的对天线进行轮询驱动，使得耗电压力大，因此，可以在车辆进入闭锁状态的情况下，第一时间段内根据第三驱动次序集合对天线进行轮询驱动，即仅在一段时间内对第三驱动次序集合包括的全部天线进行轮询，以保证短时间内车辆可以被快速启动，在第一时间段结束后可以直接关闭轮询功能，也可以进一步执行步骤305。可选地，可以将根据第三驱动次序集合对天线进行轮询驱动确定为工作模式。
本发明实施例中，第一时间段的长短可以默认设置、用户自行设置，也可以根据地点、用户使用习惯等动态设置，如可以根据车辆停放地确定第一时间段时长，车辆停放地点可以是公司停车场、小区停车场、超市停车场、便利店、餐馆等，可选地，可以通过模块电路板晶振计时或MCU(Microcontroller Unit，微控制单元)内部晶振进行RTC(Real_TimeClock)计时，本发明实施例对第一时间段的长短以及计时方式不作具体限制。
如，车辆进入闭锁状态后，在第一时间段内以第三驱动次序集合“②(数据)→③(数据)→①②③④(载波)”驱动车辆上的天线。
步骤305、在所述车辆进入闭锁状态后的第一时间段内未接收到唤醒操作的情况下，根据第四驱动次序集合在第二时间段内对所述天线进行轮询驱动，所述第四驱动次序集合包括所述车辆上车外主驾驶侧天线和车外副驾驶侧天线的驱动次序集合。
本发明实施例中，第二时间段为第一时间段后相邻的时间段，唤醒操作 指通过钥匙启动车辆的操作，在第一时间段内未接收到唤醒操作可以认为车辆可能短期内处于闲置状态，此时，在第一时间段之后的第二时间段内，可以根据第四驱动次序集合对天线进行轮询驱动，其中，第四驱动次序集合仅包括对车辆上车外主驾驶侧天线和车外副驾驶侧天线的驱动次序集合，由于用户在启动车辆时钥匙一般先靠近主、副驾驶位，因此，保留对车外主驾驶侧天线和车外副驾驶侧天线的驱动可以保证车辆钥匙定位的准确率以及响应效率。可选地，可以将根据第四驱动次序集合对天线进行轮询驱动确定为休眠模式，第二时间段可以对应参照步骤304中对第一时间段的相关描述，为避免重复，在此不再赘述。
如，在第一时间段内未接收到唤醒操作的情况下，在第二时间段内以第四驱动次序集合“②(数据)→③(数据)”驱动车辆上的天线。
步骤306、在所述车辆进入闭锁状态后的第二时间段内未接收到唤醒操作的情况下，根据第五驱动次序集合在第三时间段内对所述天线进行轮询驱动，所述第五驱动次序集合包括所述车辆上所述车外主驾驶侧天线的驱动次序集合。
本发明实施例中，第三时间段为第二时间段后相邻的时间段，在第二时间段内未接收到唤醒操作可以认为车辆可能较长期处于闲置状态，此时，在第二时间段之后的第三时间段内，可以根据第五驱动次序集合对天线进行轮询驱动，其中，第五驱动次序集合包括车外主驾驶侧天线的驱动次序集合，即除车外主驾驶侧天线外其他天线均保持休眠，从而节省耗电，可选地，可以将根据第五驱动次序集合对天线进行轮询驱动确定为预深度睡眠模式，第三时间段可以对应参照步骤304中对第一时间段的相关描述，为避免重复，在此不再赘述。
如，在第二时间段内未接收到唤醒操作的情况下，在第三时间段内以第五驱动次序集合“②(数据)”驱动车辆上的天线。
步骤307、在所述车辆进入闭锁状态后的第三时间段内未接收到唤醒操作的情况下，停止驱动所述车辆上的所述天线。
本发明实施例中，在第三时间段内未接收到唤醒操作可以认为车辆可能长期处于闲置状态，此时，可以停止驱动车辆上的天线工作，即完全关闭主动进入轮询功能，在车辆下一次被合法钥匙唤醒启动时，再开启主动进入轮 询功能。可选地，可以将停止对天线进行轮询驱动确定为深度睡眠模式，
如，在第三时间段内未接收到唤醒操作的情况下停止驱动车辆上的天线。
本发明实施例中，步骤304至步骤306中各时间段内对天线进行轮序驱动的周期可以相同也可以不同，可选地，可以是在相同或不同的时间内完成一次驱动次序集合的轮询，或者在时间段内完成相同或不同次数的驱动次序集合的轮询，本领域技术人员可以根据需求设定轮询周期，本发明实施例对此不作具体限制。
本发明实施例中，在执行步骤304至步骤306的过程中，也可以对驱动的天线进行故障诊断，从而在发现天线中存在故障天线的情况下，从对应的驱动次序集合中去除该故障天线。
步骤308、对停止驱动所述车辆上的所述天线进行提示。
本发明实施例中，在停止驱动车辆上的天线后，可以对其进行提示，可选地，可以通过车载终端向用户终端发送提示信息、短信、应用程序通知从而提示用户已停止驱动车辆上的天线，本发明实施例对此不做具体限制。
本发明实施例中，在根据第一驱动次序集合驱动车辆中的天线以进行钥匙定位的同时，对天线进行故障诊断，从而在天线中存在故障天线的情况下，根据故障天线调整第一驱动次序集合，去除故障天线，获得无需驱动故障天线的第二驱动次序集合，再根据第二驱动次序集合驱动车辆中的天线以进行钥匙定位，使得在天线中存在故障天线的情况下，可以跳过故障天线对钥匙进行定位，保证车辆的正常启动、锁定等，维持车辆的正常工作，且无需再对故障天线进行驱动，提高了驱动效率，提升用户驾驶体验。另外，在主动进入的天线轮询驱动中，本发明实施例在未接收到唤醒操作的情况下，根据时间段划分逐渐减少需要轮询的天线数量，从而降低了车辆在闲置时的耗电，降低了整车蓄电池的压力，减少了电池损耗。

天线故障诊断模块401，用于在根据第一驱动次序集合驱动车辆中的天线工作以进行钥匙定位的过程中，对驱动的所述天线进行故障诊断，所述第一驱动次序集合为所述车辆中任一功能对应的所述天线的驱动次序集合；

例如，图6示出了可以实现根据本公开的方法的计算处理设备。该计算处理设备传统上包括处理器1010和以存储器1020形式的计算机程序产品或者计算机可读介质。存储器1020可以是诸如闪存、EEPROM(电可擦除可编程只读存储器)、EPROM、硬盘或者ROM之类的电子存储器。存储器1020具有用于执行上述方法中的任何方法步骤的程序代码1031的存储空间1030。例如，用于程序代码的存储空间1030可以包括分别用于实现上面的方法中的各种步骤的各个程序代码1031。这些程序代码可以从一个或者多个计算机程 序产品中读出或者写入到这一个或者多个计算机程序产品中。这些计算机程序产品包括诸如硬盘，紧致盘(CD)、存储卡或者软盘之类的程序代码载体。这样的计算机程序产品通常为如参考图7所述的便携式或者固定存储单元。该存储单元可以具有与图6的计算处理设备中的存储器1020类似布置的存储段、存储空间等。程序代码可以例如以适当形式进行压缩。通常，存储单元包括计算机可读代码1031’，即可以由例如诸如1010之类的处理器读取的代码，这些代码当由计算处理设备运行时，导致该计算处理设备执行上面所描述的方法中的各个步骤。
本文中所称的“一个实施例”、“实施例”或者“一个或者多个实施例”意味着，结合实施例描述的特定特征、结构或者特性包括在本公开的至少一个实施例中。此外，请注意，这里“在一个实施例中”的词语例子不一定全指同一个实施例。
在此处所提供的说明书中，说明了大量具体细节。然而，能够理解，本公开的实施例可以在没有这些具体细节的情况下被实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。
在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。本公开可以借助于包括有若干不同元件的硬件以及借助于适当编程的计算机来实现。在列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
最后应说明的是：以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开各实施例技术方案的精神和范围。
