轮胎是汽车的重要部件之一，它直接与路面接触，可以用来缓和车辆行驶时所受到的冲击，保证车辆有良好的乘座舒适性和行驶平顺性。因此，在车辆高速行驶的过程中发生爆胎是非常危险的，爆胎的原因通常可以包括但不限于：轮胎漏气、轮胎气压过高、轮胎气压不足和轮胎自身发生故障(如轮胎磨损等)。
现有的预防爆胎的方法主要是通过胎压传感器在车辆行驶过程中对轮胎气压进行实时自动监测，并在轮胎漏气和轮胎气压较低时进行报警，以确保行车的安全。对于没有安装胎压传感器的车辆，驾驶员只能在开车前通过人工检查轮胎的状态。然而，通过人工检查轮胎状态的方式并不准确，而又不是所有车辆上均安装有胎压传感器，导致车辆的行驶存在安全隐患。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
另外，本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
需要说明的是，本发明的技术方案可以应用于各种机动车辆中。机动车辆中设置有爆胎预警装置，该爆胎预警装置可以与车辆控制系统相连接，也可以不与车辆控制系统相连接。在爆胎预警装置与车辆控制系统相连接的情况下，爆胎预警装置可以在监测到有爆胎危险时直接发送相应的爆胎预警信息至车辆控制系统，以使得车辆控制系统能够根据实际情况控制车辆的运行；在爆胎预警装置未与车辆控制系统相连接的情况下，爆胎预警装置自身可以具备输出设备(例如屏幕或扬声器)，爆胎预警装置在监测到有爆胎危险时发出相应的报警信息(例如警报声或者警报视频)提醒驾驶员，以使得驾驶员根据实际情况控制车辆的运行；在爆胎预警装置未与车辆控制系统相连接的情况下，爆胎预警装置还能够与其他终端设备相连接(例如手机、平板等移动终端)，当爆胎预警装置在监测到有爆胎危险时发送相应的爆胎预警信息至终端设备，以使得终端设备通过在终端设备的屏幕上显示爆胎预警信息或者发出报警声等方式提醒驾驶员，以使得驾驶员根据实际情况控制车辆的运行。
其中，终端设备可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经WIFI、蓝牙、红外及无线接入网(例如RAN，Radio Access Network)等与爆胎预警装置进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移 动装置，它们与无线接入网交换语言和/或数据。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote station)、接入点(Access point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、或用户装备(User Equipment)。
进一步地，爆胎预警装置可以内置传感器；爆胎预警装置也可以外接传感器，以接收传感器发送的轮胎的影像信息。传感器可以为一个，也可以为多个，且传感器可以设置在能获取轮胎影像信息的任意位置，通常的，传感器可以设置在轮胎挡泥板(如果车辆有安装挡泥板的话)内侧或者车辆后视镜的下侧，本发明对此不做具体限制。
还需要说明的是，本发明实施例提供的爆胎预警方法能够周期性地监测轮胎的状态，并且爆胎预警装置获取的影像信息可以是轮胎的静态影像信息或者动态影像信息，爆胎预警装置在判断轮胎是否有爆胎危险时，对于静态影像信息和动态影像信息的判断标准可以是不一样的(例如对于静态影像信息，爆胎预警装置只需判断轮胎上的某根线条是否发生偏移即可；而对于动态影像信息，若轮胎上的某根线条发生偏移，反映在动态影像信息上可能会显示成较粗的一根线条)。在本发明下述实施例中，仅以监测轮胎在一个时刻的状态、且爆胎预警装置获取的影像信息是轮胎的静态影像信息为例进行的示例性的说明。在监测的过程中，车辆可以处于静止状态，也可以处于运行的状态。对于车辆处于运行的状态的情况，本发明实施例提供的爆胎预警方法还能够实时地监测轮胎的状态，即在车辆运行的过程中，爆胎预警装置能够实时地获取轮胎在当前时刻的静态影像信息与轮胎的初始影像信息进行对比，从而判断轮胎是否有爆胎危险，本发明对此不做限制。
实施例1
本发明实施例提供一种爆胎预警方法，如图1所示，该方法包 括：
S101、爆胎预警装置获取轮胎的第一信息和第二信息，其中，第一信息为轮胎的初始影像信息，第二信息为轮胎在第一时刻的影像信息，第一时刻为获取第二信息的时刻。
可以理解的是，本发明实施例所提到的影像信息可以分为两种：(1)静态影像信息，如图片、照片等；(2)动态影像信息，如影片等。上述两种影像信息都能够通过光学设备获取，如照相机、镜子、望远镜及显微镜等。在本发明实施例中，均以光学传感器为例获取影像信息，光学传感器可以包括但不限于：光学图像传感器、透射型光学传感器、光学测量传感器、光学鼠标传感器、红外图像传感器以及反射型光学传感器等。
需要说明的是，第一信息可以是车辆出厂时车辆上的轮胎的影像信息，此时，第一信息可以预先存储在爆胎预警装置中；同时，第一信息也可以是设定好的轮胎处于正常状态下的影像信息，此时，第一信息可以预先存储在爆胎预警装置中，也可以在需要判断轮胎的状态时临时生成，本发明对此不做限制。
在第一种可能的实现方式中，如图2所示，爆胎预警装置中内置了光学传感器，则步骤S101可以包括步骤S101a和S101b：
S101a、爆胎预警装置获取预设的轮胎的第一信息。
爆胎预警装置能够存储轮胎的第一信息，当爆胎预警装置需要判断轮胎的状态时，直接获取预设的轮胎的第一信息即可。
S101b、爆胎预警装置读取轮胎的第二信息。
对于爆胎预警装置中内置了光学传感器的情况，当光学传感器获取了轮胎的第二信息之后，爆胎预警装置能够直接读取轮胎的第二信息。
在第二种可能的实现方式中，如图3所示，爆胎预警装置中内置了光学传感器，则步骤S101可以包括步骤S101c和S101d：
S101c、爆胎预警装置读取轮胎的第一信息。
若爆胎预警装置中原本并不存储轮胎的第一信息，则爆胎预警 装置中内置的光学传感器理论上可以选择在第一时刻之前的任一时刻，获取第一信息(只要轮胎在选择的时刻时处于正常状态即可)，以使得爆胎预警装置能够读取轮胎的第一信息。通常的，爆胎预警装置中内置的光学传感器可以选择在车辆启动前的时刻获取第一信息。
S101d、爆胎预警装置读取轮胎的第二信息。
具体的，步骤S101d所描述的内容与上述步骤S101b所描述的内容相同，为了简洁，此处不再赘述。
在第三种可能的实现方式中，如图4所示，爆胎预警装置中未内置光学传感器，且爆胎预警装置与外部光学传感器相连接，则步骤S101可以包括步骤S101e和S101f：
S101e、爆胎预警装置获取预设的轮胎的第一信息。
具体的，步骤S101e所描述的内容与上述步骤S101a所描述的内容相同，为了简洁，此处不再赘述。
S101f、爆胎预警装置接收光学传感器发送的轮胎的第二信息。
对于爆胎预警装置中未内置光学传感器，且爆胎预警装置与外部光学传感器相连接的情况，当光学传感器获取了轮胎的第二信息之后，光学传感器发送轮胎的第二信息至爆胎预警装置，以使得爆胎预警装置接收光学传感器发送的轮胎的第二信息。
在第四种可能的实现方式中，如图5所示，爆胎预警装置中未内置光学传感器，且爆胎预警装置与外部光学传感器相连接，则步骤S101可以包括步骤S101g：
S101g、爆胎预警装置接收光学传感器发送的轮胎的第一信息和第二信息。
具体的，若爆胎预警装置中原本并不存储轮胎的第一信息，则爆胎预警装置中内置的光学传感器理论上可以选择在第一时刻之前的任一时刻，获取第一信息(只要轮胎在选择的时刻时处于正常状态即可)，并发送第一信息至爆胎预警装置。
随后，在第一时刻，光学传感器获取轮胎的第二信息，并发送 第二信息至爆胎预警装置。
S102、爆胎预警装置将第一信息和第二信息进行对比，确定轮胎的形变量是否大于或者等于预设阈值。
具体的，轮胎的形变量可以是轮胎的胎面或者胎侧上的一整根线条与原位置的相对偏移量，或者是轮胎的胎面或者胎侧上的一根线条的局部发生形变后，线条形变呈现的曲线的顶点与原位置的相对距离，本发明对此不作限制。
优选的，如图6所示，步骤S102可以包括S102a-S102d：
S102a、爆胎预警装置选择轮胎的胎面或者胎侧上的至少一个线条。
可以理解的是，轮胎的胎面或者胎侧可以包含多个线条，如轮胎的胎面或者胎侧的轮廓线、轮胎的胎面或者胎侧上的花纹，或者轮胎的胎面或者胎侧上的指定位置的线条等。通常，为了判断的准确性，爆胎预警装置会选择位于轮胎的胎面或者胎侧中央的一个线条。
S102b、爆胎预警装置确定线条的第一位置和第二位置，其中，第一位置为线条在第一信息中的位置，第二位置为线条在第二信息中的位置。
S102c、爆胎预警装置根据第一位置和第二位置，计算第二位置相对于第一位置的最大偏移量。
S102d、爆胎预警装置确定最大偏移量大于或者等于预设阈值。
进一步地，预设阈值为轮胎的胎面或者胎侧的宽度的1/n，其中，n为正整数。可以理解的是，n的取值可以根据实际情况设定。
示例性的，以爆胎预警装置选择轮胎的胎面上的一个线条为例，如图7所示，为轮胎的胎面的俯视图，图7中的(a)为爆胎预警装置获取的轮胎的胎面的第一信息以及线条的第一位置，图7中的(b)为爆胎预警装置获取的轮胎的胎面的第二信息以及线条的第二位置，图7中的(c)为将图7中的(a)和图7中的(b)重叠后的轮胎的胎面的俯视图。其中，线条的第二位置相对于第一位置的最大 偏移量为d1，轮胎的胎面的宽度为D1，此时，爆胎预警装置只需要确定d1是否大于或者等于D1/n，即可确定出轮胎是否存在爆胎的危险。
又示例性的，以爆胎预警装置选择轮胎的胎侧上的一个线条为例，如图8所示，为轮胎的胎侧的俯视图，图8中的(a)为爆胎预警装置获取的轮胎的胎侧的第一信息以及线条的第一位置，图8中的(b)为爆胎预警装置获取的轮胎的胎侧的第二信息以及线条的第二位置，图8中的(c)为将图8中的(a)和图8中的(b)重叠后的轮胎的胎侧的俯视图。其中，线条的第二位置相对于第一位置的最大偏移量为d2，轮胎的胎侧的宽度为D2，此时，爆胎预警装置只需要确定d2是否大于或者等于D2/n，即可确定出轮胎是否存在爆胎的危险。
本发明实施例提供的判断轮胎是否存在爆胎危险的方法只是一种可实现的方式，爆胎预警装置还可以通过对比线条在第一信息和第二信息中分别占图像像素的多少，或者占画面比例的多少来判断轮胎是否存在爆胎危险；爆胎预警装置还可以通过识别轮胎的影像信息上的线条是否存在异常，来推测轮胎是否有凸包或者轮胎是否有异物(例如小石子，铁钉等)，来判断轮胎是否存在爆胎危险，或者爆胎预警装置还可以直接识别轮胎是否有凸包或异物，本发明对此不做具体限制。
示例性的，如图9所示，为轮胎的胎面的俯视图，当轮胎的胎面有异物时，爆胎预警装置识别到轮胎的影像信息上的出现异常线条，从而能够判断轮胎存在爆胎危险。
S103、若轮胎的形变大于或者等于预设阈值，则爆胎预警装置生成爆胎预警信息。
需要补充的是，当爆胎预警装置检测到轮胎的形变大于或者等于预设阈值后，为了判断的准确性，爆胎预警装置还可以连续监测几个周期内轮胎的形变是否均大于或者等于预设阈值，若在几个周期内轮胎的形变均大于或者等于预设阈值，则爆胎预警装置生成爆 胎预警信息。
可选的，爆胎预警装置还可以同时选择轮胎的胎面或者胎侧上的多个线条，只要当爆胎预警装置确定多个线条中的任意一个线条发生的最大偏移量大于或者等于预设阈值，爆胎预警装置就会生成爆胎预警信息。
可以理解的是，若轮胎的形变不大于预设阈值，则表示轮胎处于正常状态，此时无须执行任何动作。
进一步地，如图10所示，若爆胎预警装置与车辆控制系统相连接，则在步骤S103执行之后，爆胎预警方法还包括步骤S104：
S104、爆胎预警装置发送爆胎预警信息至车辆控制系统，以使得车辆控制系统根据爆胎预警信息控制车辆的运行。
在爆胎预警装置与车辆控制系统相连接的情况下，爆胎预警装置可以在监测到有爆胎危险时直接发送爆胎预警信息至车辆控制系统，以使得车辆控制系统能够根据实际情况生成与爆胎预警信息对应的控制信息，从而控制车辆的运行；同理可知，在爆胎预警装置未与车辆控制系统相连接的情况下，爆胎预警装置可以在监测到有爆胎危险时发出报警信息(例如警报声)提醒驾驶员，以使得驾驶员根据实际情况控制车辆的运行。
本发明实施例提供一种爆胎预警方法，通过获取轮胎的第一信息和第二信息，其中，第一信息为轮胎的初始影像信息，第二信息为轮胎在第一时刻的影像信息，第一时刻为获取第二信息的时刻；将第一信息和第二信息进行对比，确定轮胎的形变量大于或者等于预设阈值；生成爆胎预警信息。基于上述实施例的描述，由于爆胎预警装置能够获取并对比轮胎的第一信息和第二信息，确定出轮胎的形变量是否大于或者等于预设阈值，从而判断出轮胎是否存在爆胎隐患。与传统的通过人工检查轮胎状态的方式相比，能够监测轮胎的状态，排除车辆行驶的安全隐患；与在车辆上均安装胎压传感器的方式相比，无需将爆胎预警装置安装在轮胎内部，简化了安装步骤，节约了成本。
