Description

胎压传感器识别方法及相关装置、系统
本申请要求于2017年01月17日提交中国专利局、申请号为201710036080.X、申请名称为“胎压传感器识别方法及相关装置、系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及车辆技术领域，尤其涉及一种胎压传感器识别方法及相关装置、系统。
背景技术
胎压监控系统(Tire Pressure Monitor System，TPMS)主要包括间接式和直接式两种类型。间接式TPMS是通过汽车防抱死制动系统(Anti-lock Braking System，ABS)的轮速传感器来比较轮胎之间的转速差别，以达到监测胎压的目的，属于事后被动型。直接式TPMS是利用安装在每一个轮胎里的胎压传感器来直接测量轮胎的气压，属于事前主动预防型。由于前者确定故障的准确性不如后者，目前多采用直接式TPMS。
直接式TPMS一般包括胎压传感器和电子控制单元(Electronic Control Unit，ECU)，在初始化时一般须使其电子控制单元保存所有胎压传感器的识别码，以确保电子控制单元可以识别到每一个轮胎中的胎压传感器。同时，只有在胎压传感器处于激活状态时，电子控制单元才能够识别到该胎压传感器发出的射频信号，进而读取到相应的识别码。
在胎压传感器的识别过程中，因为胎压传感器的激活时间有限制，一旦胎压传感器的激活时段结束(即进入休眠状态的胎压传感器为节能，不会发出射频信号)，而电子控制单元又没来得及在该时段中进行识别，则针对该胎压传感器的识别过程必须重新开始。所以，为了避免错过胎压传感器的激活时段，现有的实施方案是每一个轮胎均需要单独进行一次识别操作，才能保证电子控制单元识别到每一个胎压传感器。整个识别过程下来，用户需要从轮胎位置到驾驶室往返多次且重复操作。尤其是在两轮以上的车辆中，采用上述识别方法的胎压传感器的识别操作效率低下。

具体实施方式
体现本发明特征与优点的典型实施方式将在以下的说明中详细叙述。应理解的是本发明能够在不同的实施方式上具有各种的变化，其皆不脱离本发明的范围，且其中的说明及图示在本质上是当作说明之用，而非用以限制本发明。
首先详细介绍下现有技术中胎压监控的工作原理和胎压传感器的识别步骤。胎压监控系统(直接式TPMS)一般通过在每个轮胎中内置胎压传感器，并接收该胎压传感器发回的无线信号(射频信号)来了解每个轮胎的压力值。在对汽车轮胎胎压进行监控时，胎压监控系统中的电子控制单元(一般为带有无线通信功能的单片机或者电脑)必须先记录下每个轮胎中胎压传感器的识别码(识别ID)以及该胎压传感器对应的轮胎。这个记录的过程就是电子控制单元识别胎压传感器的过程。识别完毕后该识别码和对应的轮胎位置信息保存在电子控制单元中，电子控制单元再接收到包含该识别码的无线信号时会一并读取到该无线信号中的胎压信息，即电子控制单元获得了相应轮胎的胎压信 息，并直观的显示给驾驶员。
一般情况下，因为胎压传感器设置在轮胎中，无法通过线缆连接，只能通过无线信号(一般为射频信号)与电子控制单元通信。且由于胎压传感器内设电池无法充电，为了节省电能，胎压传感器在通常情况下会进入休眠模式节省电能。只有在被专门的激活信号(低频信号，耗电小但传输距离短)激活或者轮胎漏气(胎压发生变化)又或者轮胎运动时才会发出携带有身份信息(识别码)以及胎压信息的无线信号(射频信号)。同时，由于通常采用一体设计缩小体积的关系，胎压传感器的电池用尽后只能整体更换。每次更换胎压传感器后，电子控制单元都必须重新识别新的胎压传感器。
以下参考附图1-6，对本发明的各实施例予以进一步地详尽阐述。
请参阅图1，本发明实施例提供了一种胎压传感器识别装置。如图1所示，该胎压传感器识别装置1包括：存储模块10、通信模块20、处理模块30以及射频发射模块40；其中，存储模块10、通信模块20以及射频发射模块40分别与处理模块30通信连接；
存储模块10用于存储胎压传感器2的身份信息；
通信模块20用于与车辆的电子控制单元3进行通信，并接收电子控制单元3反馈的应答信息；
处理模块30用于对通信模块20接收到的应答信息进行解析，以判断电子控制单元3是否开启传感器学习模式，若开启，控制射频发射模块40发送车辆对应的胎压传感器2的身份信息。
具体的，通信模块20可以通过无线或有线的方式与车辆的电子控制单元3(ECU)进行通信连接，连接后，通信模块20可以向车辆发起传感器学习请求，并接收车辆的电子控制单元3(ECU)反馈的应答信息。其中，该应答信息用于指示该车辆是否成功开启了传感器学习模式，可以包括但不限于车辆的相关信息，如车辆的型号、制造商、车牌号等信息。在电子控制单元3开启学习模式后(胎压监控系统的电子控制单元3通常位于车辆内部，车辆开启学习模式的实质就是电子控制单元3开启了学习模式)，胎压传感器识别装置1将保存的身份信息，以模拟胎压传感器2被激活时发出无线信号的方式将相应的身份信息统一发送给电子控制单元3。这样，在操作者不方便激活胎压传感器2；或者胎压传感器2已经进入激活时段，而电子控制单元3却不方便启动学习模式时，通过本发明胎压传感器识别装置1的信号模拟，无论胎压传感器2是否激活，电子控制单元3都可以记录到胎压传感器2的身份信息，方便了胎压监控系统的识别操作。在本实施例中，处理模块30为胎压传感器识别装置1的控制中心，可以为微控制单元(Micro Controller Unit，MCU)，用于控制胎压传感器识别装置1的各项操作。
在本实施例中，存储模块10中存储的胎压传感器2的身份信息可以是胎压传感器识别装置1在开发时由研发人员写入进存储模块10中的，也可以是胎压传感器识别装置1从外部获取到的并保存到存储模块10中的，本发明实 施例不作限定。存储模块10中可以存储一个或多个胎压传感器2的身份信息，也可以存储不同类型车辆的胎压传感器的身份信息。
需要强调的是，在本发明实施例中，胎压传感器2的身份信息用于唯一标识胎压传感器2，不同的胎压传感器2的身份信息不同。其主要包括胎压传感器2的识别码。识别码一般为胎压传感器2的唯一物理地址，以区别于其他轮胎中的胎压传感器2。
在其他实施例中，胎压传感器2的身份信息包括但不限于胎压传感器2的识别码、型号、生产厂商、使用日期、电池容量信息等信息。
在其他实施例中，通信模块20还可以用于实现胎压传感器识别装置1的对外通信。例如与电子控制单元3的信息交互，或者与汽车的车载自动诊断系统的信息交互，该通信模块20的通信方式可以采用有线或无线的连接方式实现通信。
在本实施例中，存储模块10还用于存储不同类型车辆的胎压传感器2的通信频率，以便于胎压传感器识别装置1兼容或者识别不同种类的车辆。具体而言，胎压传感器2的通信频率会根据所适配的车辆类型采用相应的通信频率。存储模块10存储的不同类型车辆的胎压传感器2的通信频率，如车辆类型1对应的胎压传感器2的通信频率为f1，车辆类型2对应的胎压传感器2的通信频率为f2等等，从而使本发明涉及的胎压传感器识别装置1可以兼容多种不同类型的车辆(胎压传感器)。一般地，同一车辆上的胎压传感器2均采用同一个通信频率；同一类型的车辆上的胎压传感器2的通信频率相同，不同类型的车辆上的胎压传感器2的通信频率不同。胎压传感器2的通信频率一般采用射频频率。射频信号具有较高的抗干扰性和较长的传播距离，便于胎压传感器2实时发送轮胎的压力信息至车厢内的电子控制单元3。
具体的，射频发射模块40用于模拟车辆的胎压传感器2的通信频率发送车辆对应的胎压传感器2的身份信息。
在具体实施中，处理模块30解析车辆反馈的应答信息，可以获取到车辆的型号，从而根据车辆的型号从存储模块10中获取该型号对应的胎压传感器的通信频率，并控制射频发射模块40模拟该通信频率发送车辆对应的胎压传感器的身份信息。该射频发射模块40采用模拟通信频率的形式进行信息发送工作，用以在电子控制单元3识别胎压传感器2的过程中模拟胎压传感器2，便于电子控制单元3识别。通过上述方案，本发明的胎压传感器识别装置1可以在胎压传感器2没有激活的情况下，代替其发送身份信息给电子控制单元3进行识别。
在其他实施例中，射频发射模块40也可以通过通信线缆将存储模块10中保存的胎压传感器2的身份信息发送给电子控制单元3，已完成电子控制单元3对胎压传感器2的识别。
可选的，射频发射模块40可以一次只发射车辆上一个胎压传感器2的身份信息，即一次学习过程只识别一个胎压传感器2，如果要识别车辆上的多个 胎压传感器2则需要多次开启车辆的学习模式；也可以一次发射车辆上多个或全部胎压传感器2的身份信息，即一次学习过程即可完成车辆上多个或所有胎压传感器2的识别。
在本实施例中，胎压传感器识别装置1还包括：获取模块50，与处理模块30通信连接，用于获取胎压传感器2的身份信息，并经由处理模块30处理后存储至存储模块10。
通过将车辆中需要识别的胎压传感器2发出的身份信息进行统一获取或采集，可以避免每识别一个胎压传感器2就必须对电子控制单元3进行一次操作的繁琐流程，同时，也方便电子控制单元3一次性的识别所有胎压传感器2。
如附图2所示，在第一种实施例中，获取模块50包括激活模块51和射频接收模块52，激活模块51用于通过输出低频信号激活胎压传感器2；射频接收模块52用于接收被激活的胎压传感器2发出的身份信息。
其中，激活模块51与射频接收模块52分别与处理模块30通信连接。具体的，处理模块30控制激活模块51通过输出低频信号激活胎压传感器2，使胎压传感器2外发身份信息。此外，胎压传感器2在向外发送身份信息的同时，还会发送当前所在轮胎的气压信息(如轮胎的压力值、温度值等)等。由于胎压传感器2的电池不可更换，在轮胎气压不变或者没有接收到激活信号时，胎压传感器2均处于休眠状态，用以节省电池消耗。因此，在需要识别胎压传感器2时，现有的实现方式是采用充、放气的形式改变轮胎气压，则胎压传感器2因为气压改变而进入激活状态，向外发送无线信号(包括身份信息和轮胎气压信息等)，一般为射频信号。但是对轮胎充、放气的激活方式操作复杂，本发明采用在获取模块50中设置发送低频信号的激活模块51，使休眠中的胎压传感器2可以被低频信号激活，省去了给轮胎进行充、放气的繁琐操作，使胎压传感器2的激活更加方便。
同时，射频接收模块52采用射频信号接收器来接收胎压传感器2在收到低频信号或者轮胎压力变化时被激活而发出的射频信号，并将接收到的射频信号发送至处理模块30进行处理，之后再发送至存储模块10中进行保存。其中，该射频信号除包括胎压传感器2的身份信息外，还可以包括该胎压传感器2测得的气压信息等。通过上述方式，可以将待识别的一个或多个胎压传感器2的身份信息保存至存储模块10中，以便车辆的电子控制单元3开启传感器学习模式时，由射频发射模块40模拟发送胎压传感器2的身份信息，以完成车辆对胎压传感器2的学习功能。
如附图3所示，在第二种实施例中，获取模块50可以包括输入模块53，输入模块53用于接收用户输入的胎压传感器2的身份信息。
其中，输入模块53与处理模块30进行通信连接。输入模块53接收用户主动输入的胎压传感器2的识别码(身份信息)，并与存储模块10中存储的不同类型车辆的胎压传感器2的通信频率进行匹配。并将该匹配关系进行保存。通过输入识别码与预存的通信频率匹配这一操作，使得胎压传感器识别装置1 可以不用激活胎压传感器2，仅通过已知的识别码就可以匹配到相应的身份信息，并提供给电子控制单元3。同时，也方便当电子控制单元3开启学习模式而胎压传感器2不方便激活时，射频发射模块40可以模拟出相应的射频信号，使胎压传感器2的身份信息可以及时传递到电子控制单元3中。
具体实施时，输入模块53为一般文字输入设备或者代码输入设备(该代码包括但不限于条码、二维码等)，便于用户主动输入胎压传感器2的识别码，如条形码、二维码或者相应便于主动输入的数字和/或字符代码等。该输入模块53也可以采用键盘或手写屏幕或二者的结合，或者采用便于接收中间设备或辅助设备输入识别信息的输入装置，如摄像头、条码/二维码扫描装置、点对点信息传送装置等。
在优选的实施例中，第一实施例可以和第二实施例合并实施，使胎压传感器识别装置1不仅可以从被激活的胎压传感器2中获取身份信息，也可以通过用户输入的形式获取该身份信息。
在优选的实施例中，胎压传感器识别装置1还包括：显示模块(图中未示出)，与处理模块30通信连接，用于显示获取的胎压传感器2的身份信息以及工作状态。其中，工作状态可以包括但不限于胎压传感器2检测到的轮胎的压力值、温度值、胎压传感器2的剩余电量等等。通过设置显示模块可以方便用户直观的了解当前的操作状态和获取到的身份信息，使得胎压传感器2的使用可以更为方便且人性化。此外，用户通过显示模块查看胎压传感器2的相关信息，并可以对胎压传感器2的信息进行相应修改，如修改胎压传感器2的识别码，确认后对修改后的信息进行保存。
请参阅图4，本发明实施例还提供一种胎压传感器识别系统。如附图4所示，该胎压传感器识别系统可以包括：胎压传感器2、电子控制单元3以及上述实施例中所描述的胎压传感器识别装置1；胎压传感器识别装置1分别与电子控制单元3、胎压传感器2通信连接。
在具体实施时，胎压传感器识别装置1中的通信模块20与电子控制单元3通信连接，胎压传感器识别装置1中的激活模块51、射频接收模块52分别与胎压传感器2通信连接。胎压传感器识别装置1统一采集并存储各轮胎中的胎压传感器2的身份信息，在电子控制单元3需要识别胎压传感器2时，如胎压监控系统第一次启动或者某个胎压传感器2因电池失效或者其他原因更换后，胎压传感器识别装置1即可模拟相应的胎压传感器2发出射频信号，方便电子控制单元3进行识别。避免了识别时需要激活胎压传感器2的操作限制，以及在胎压传感器2激活时段内必须回到驾驶室操作电子控制单元3进行识别的操作限制。使得该胎压传感器2识别系统的识别操作快速且高效，也方便了用户操作。胎压传感器识别装置1的组成模块和具体功能请参考上述实施例中所描述的部分或全部内容，在此将不再赘述。
请参阅图5，本发明实施例还提供一种胎压传感器识别方法。其中，该胎压传感器识别方法应用于上述实施例中所涉及的胎压传感器识别装置1。如附图5所示，该方法包括以下步骤：
510、在建立与车辆的电子控制单元3的通信连接后，接收电子控制单元3反馈的应答信息；
520、对接收到的应答信息进行解析，以判断电子控制单元3是否开启传感器学习模式，若开启，从存储的胎压传感器2的身份信息中获取车辆对应的胎压传感器2的身份信息；
530、向电子控制单元3发送车辆对应的胎压传感器2的身份信息。
在本实施例中，胎压传感器识别装置1可以通过无线或有线的方式与车辆的电子控制单元3(ECU)进行通信连接，连接后，胎压传感器识别装置1向车辆发起传感器学习请求，并接收车辆的电子控制单元3(ECU)反馈的应答信息。其中，该应答信息用于指示该车辆是否成功开启了传感器学习模式，可以包含车辆的相关信息，如车辆的型号、制造商、车牌号等信息。进一步的，对该应答信息进行解析，以判断车辆是否开启了传感器学习模式，如果开启了，则可以从预先存储在胎压传感器识别装置1中的胎压传感器2的身份信息中获取到该车辆对应的胎压传感器2的身份信息，并将该身份信息发送给车辆，从而使车辆完成识别操作。
在本实施例中，胎压传感器2的身份信息包括胎压传感器2的识别码，用于唯一标识胎压传感器2，不同的胎压传感器2的身份信息不同。可以理解的是，预先存储的胎压传感器2的身份信息可以是胎压传感器识别装置1在开发时由研发人员写入进存储模块10中的，也可以是胎压传感器识别装置1从外部获取到的并保存到存储模块10中的，本发明实施例不作限定。
在其他实施例中，身份信息还包括但不限于：型号、生产厂商、使用日期、电池容量信息等具体数据。
在本实施例中，通过握手操作，胎压传感器识别装置1可以与设置在车辆内部的电子控制单元3建立相对稳定的连接，使得电子控制单元3识别胎压传感器2时不需要逐一对其进行激活操作，简化了识别流程。
同时，也有效避免了胎压传感器识别装置1单方面长时间发送信息而浪费电能，以延长其续航时间，尤其是其采用手持设备的实施形式的时候。
在一优选的实施例中，如附图6所示，在执行步骤510在建立与车辆的电子控制单元3的通信连接后，接收电子控制单元3反馈的应答信息之前，该胎压传感器识别方法还可以包括以下步骤：
200、通过输出低频信号激活胎压传感器2；
300、接收被激活的胎压传感器2发出的身份信息，并保存。
上述方案为通过激活方式获取胎压传感器2身份信息的方案。激活过程中获取胎压传感器2发出的射频信号和其中包含的身份信息。
在一优选的实施例中，如附图6所示，在执行步骤510在建立与车辆的电 子控制单元3的通信连接后，接收电子控制单元3反馈的应答信息之前，该胎压传感器识别方法还可以包括以下步骤：
400、接收用户输入的胎压传感器2的身份信息，并保存。
该方案为通过接收用户输入身份信息的方式识别与该身份信息唯一对应的胎压传感器2。其中必须有预设的不同车辆类型的胎压传感器2通信频率作为支持，才能将输入的身份信息与预设的通信频率进行匹配，进而使得电子控制单元3可以通过被匹配通信频率和身份信息与胎压传感器2实现通信。具体的，当电子控制单元3进入学习模式时，胎压传感器识别装置1通过被匹配的通信频率发出该身份信息给电子控制单元3，即相当于电子控制单元3识别了与之对应的胎压传感器2。
在本实施例中，在执行步骤510在建立与车辆的电子控制单元3的通信连接后，接收电子控制单元3反馈的应答信息之前，该胎压传感器识别方法还可以包括以下步骤：
100、预先存储不同类型车辆的胎压传感器2的通信频率。
其中，步骤530向电子控制单元3发送车辆对应的胎压传感器2的身份信息具体可以包括以下步骤：
531、通过模拟车辆的胎压传感器2的通信频率向电子控制单元3发送车辆对应的胎压传感器2的身份信息。
具体的，胎压传感器识别装置1可以根据应答信息中包含的该车辆的型号，从预先存储的通信频率中获取与该车辆的型号对应的胎压传感器2的通信频率。通过胎压传感器识别装置1模拟胎压传感器2的通信频率，使得电子控制单元3在胎压传感器2未被激活的时间段以外也可以接收到与胎压传感器2相同的射频信号，并从中获取该胎压传感器2的识别码及其他身份信息。该步骤使得电子控制单元3的识别过程不需要同步的激活胎压传感器2，便于用户对电子控制单元3的操作，也省去了用户在轮胎和驾驶室之间往复来回的奔波，提高了胎压传感器识别系统的识别效率。
综上，本发明的胎压传感器识别装置1可以将胎压传感器2的身份信息存储在存储模块10中，并且通过射频发射模块40模拟胎压传感器2发送相应的身份信息，避免了电子控制单元3识别胎压传感器2时该传感器必须是激活状态的操作限制。通过本发明的胎压传感器识别装置1，电子控制单元3可以随时识别胎压传感器2，不必一定要局限在胎压传感器2激活的时段内进行识别。简化了电子控制单元3的识别操作，也方便了用户的使用。采用本发明胎压传感器识别装置1的胎压传感器识别系统以及胎压传感器识别方法，也同样具有上述优点。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
