下面通过具体实施方式结合附图对本发明实施例作进一步详细说明。
车载终端与手机的有线连接方式给用户的使用带来了局限，也就是，用户只能把手机固定在车载底座上使用，用户使用的时候非常不方便。
本实施例提供一种全新的车载终端，如图1所示，该车载终端主要包括：
车辆信息获取模块11，设置为从自身存储空间或车辆内部的数据存储空间获取原始车辆信息；
第一数据处理模块12，设置为对车辆信息获取模块11获取的所述原始车辆信息进行预设处理，得到目标车辆信息，所述目标车辆信息具有比所述原始车辆信息更小的数据传输量；
第一无线通信模块13，设置为将所述目标车辆信息以无线方式发送给外部终端。
如果该车载终端还包括存储模块，可以在存储模块中存储原始车辆信息，车辆信息获取模块11可以设置为从该存储模块获取原始车辆信息，即从自身存储空间获取原始车辆信息。或者该车载终端之外，车辆内部具有数据存储空间，车辆信息获取模块11可以设置为从该数据存储空间获取原始车辆信息，车辆信息获取模块11与该数据存储空间可以以接触式通信方式通信，包括有线连接。原始车辆信息包括至少一种车辆信息，比如油位、轮胎压力、当前车速等。
第一数据处理模块12主要设置为减小原始车辆信息的数据传输量，减小后得到的信息，称为目标车辆信息，作为一种实施例：
第一数据处理模块12包括：
归一化处理模块，设置为车辆信息获取模块11获取的原始车辆信息按照预设归一化规则进行归一化处理，得到中间车辆信息；
编码模块，设置为对所述中间车辆信息按照预设编码规则进行编码，得到目标车辆信息。
该种方式是先将原始车辆信息进行归一化处理，目的是把不同来源的数据统一到一个参考系下，再以编码的方式减小原始车辆信息的数据传输量。
由于通常需要采集的车辆信息不只一种，可选的，每种车辆信息经过归一化处理和编码后可以得到一个字节的目标车辆信息。下面举例说明：
可以将对归一化规则和编码规则内置在代码中，最终，每一种车辆信息经过归一化处理和编码后转换成一个字节大小的目标车辆信息。
例如车辆信息获取模块11获取到的原始车辆信息中包括油位信息，即油箱中剩余油量信息X，归一化处理模块先根据车辆油箱容量L，计算剩余油位百分比：Y＝X/L，剩余油位百分比Y作为归一化处理后得到的中间车辆信息，编码模块按照预设的编码规则一：剩余油位百分比在0-10％时，编码为0x00，表示急需加油；在10％-30％时，编码为0x01，表示油量不足；在30％-60％时，编码为0x02，表示油量良好；在60％-80％时，编码为0x04，表示油量充足；在80％-100％时，编码为0x08，表示油量饱满；假设归一化处理模块得到的剩余油位百分比为10％-30％，则按照上述的编码规则一，编码模块将其编码为0x01，作为目标车辆信息。
又如，车辆信息获取模块11获取到的原始车辆信息中包括轮胎压力值，标准大气压为101.325kPa，轮胎的实际压力值大于或等于标准大气压，如果不经过归一化处理和编码，实际压力值太大，占用较多的传输流量，会影响传输效率，所以，车辆信息获取模块11获取到实际轮胎压力值后，归一化处理模块将其除以一个标准值(这个标准值可以是一个标准大气压，也可以是n个标准大气压)，获得一个倍数M，将倍数M作为中间车辆信息，编码模块对M进行区间判定，不同区间对应不同的编码，比如预设的编码规则二为：区间在0-1时，编码为0x01；在1-3时，编码为0x02；在3-5时，编码为0x03；当归一化处理模块得到的倍数M为0-1时，编码模块按照上述的编码规则二，将其编码为0x01。一个字节可以对64个区段进行编码；编
码取值范围为：0X00----0XFF，共64个值。
第一无线通信模块13包括：蓝牙模块，主要设置为将第一数据处理模块12处理得到的目标车辆信息以无线方式发送给外部终端。可选的，该蓝牙模块支持Ble Advertising功能和Ble scan功能。蓝牙模块可以定时向外部终端发送Ble Advertising，其中携带目标车辆信息。

步骤S202主要用于减小原始车辆信息的数据传输量，减小后得到的信息，称为目标车辆信息，作为一种实施例，步骤S202先对原始车辆信息按照预设归一化规则进行归一化处理，得到中间车辆信息；再对中间车辆信息按照预设编码规则进行编码，得到目标车辆信息，该种方式是以归一化处理和编码的方式减小原始车辆信息的数据传输量。
由于通常需要采集的车辆信息不只一种，可选的，每种车辆信息经过归一化处理和编码后可以得到一个字节的目标车辆信息。下面举例说明：
可以将对归一化规则和编码规则内置在代码中，最终，每一种车辆信息
经过归一化处理和编码后转换成一个字节大小的目标车辆信息。例如获取到的原始车辆信息中包括油位信息，即油箱中剩余油量信息X，步骤S202先根据车辆油箱容量L，计算剩余油位百分比：Y＝X/L，剩余油位百分比Y作为归一化处理后得到的中间车辆信息，步骤S203按照预设的编码规则一：剩余油位百分比在0-10％时，编码为0x00，表示急需加油；在10％-30％时，编码为0x01，表示油量不足；在30％-60％时，编码为0x02，表示油量良好；在60％-80％时，编码为0x04，表示油量充足；在80％-100％时，编码为0x08，表示油量饱满；当步骤S202得到的剩余油位百分比为10％-30％时，按照上述的编码规则一，将其编码为0x01。
又如，获取到的原始车辆信息中包括轮胎压力值，标准大气压为101.325kPa，轮胎的实际压力值大于或等于标准大气压，如果不经过归一化处理和编码，实际压力值太大，占用较多的传输流量，会影响传输效率，所以，获取到实际轮胎压力值后，步骤S202先将其除以一个标准值(这个标准值可以是一个标准大气压，也可以是n个标准大气压)，获得一个倍数M，将倍数M作为中间车辆信息，对M进行区间判定，不同区间对应不同的编码，比如预设的编码规则二为：区间在0-1时，编码为0x01；在1-3时，编码为0x02；在3-5时，编码为0x03；当步骤S202得到的倍数M为0-1时，按照上述的编码规则二，将其编码为0x01。
步骤S203中的无线方式包括：蓝牙通信，该步骤可以包括：定时向外部终端发送Ble Advertising，其中携带目标车辆信息。

原始车辆信息更小的数据传输量；
显示模块33，设置为对所述原始车辆信息进行显示。
其中，第二无线通信模块31设置为与前述实施例提供的车载终端的第一无线通信模块13配合通信，包括：蓝牙模块，主要设置为从车载终端的第一无线通信模块13获取目标车辆信息。可选的，支持Ble Advertising功能和Ble scan功能，可以定时接收第一无线通信模块13发送的Ble Advertising，其中携带目标车辆信息。
第二数据处理模块32，主要设置为从目标车辆信息中恢复出原始车辆信息，其解析规则与前述实施例提供的车载终端的第一数据处理模块12的处理规则相适配，假设第一数据处理模块12为归一化处理模块和编码模块，以归一化处理和编码的方式将原始车辆信息处理成目标车辆信息的，则第二数据处理模块32为解码模块和反归一化处理模块，解码模块按照与编码模块的编码规则对应的解码规则对目标车辆信息进行解码，得到中间车辆信息，反归一化处理模块按照与归一化处理模块的归一化规则对应的反归一化规则对中间车辆信息进行反归一化处理，恢复出原始车辆信息。
假设每种车辆信息经过归一化和编码后得到一个字节的目标车辆信息。则解码模块可以分别对每一个字节的目标车辆信息按照对应的预设解码规则进行解码，解析出一种中间车辆信息，反归一化处理模块再按照对应的反归一化规则将该中间车辆信息还原成对应的原始车辆信息。下面举例说明：
假设车载终端将油位信息X转换成编码0x01，传输到本实施例的终端，则解码模块按照如下与编码规则一对应的解码规则进行解码：0x00，表示剩余油位百分比在0-10％；0x01，表示油位百分比在10％-30％；0x02，表示油位百分比在30％-60％时；0x04，表示油位百分比在60％-80％时；0x08，表示油位百分比在80％-100％；按照上述的解码规则，解码模块从编码0x01解析出：油位百分比Y在10％-30％，作为中间信息，反归一化处理模块先根据车辆油箱容量L，和油位百分比Y，计算油位信息：X＝L*Y，计算出的油位信息X可以通过显示模块33进行显示。
本实施例提供的终端包括手机，可以在终端中安装对应的APP，来提供人机交互，基于该人机交互从车载终端获取车辆信息，并进行显示。本实施
例提供的终端与前述实施例提供的车载终端配合，以无线方式采集车辆信息，不受有线连接的限制，而且节省了数据传输量，提高了数据传输效率，方便了用户使用。
本实施例还提供了一种应用于该车载的车辆信息采集方法，如图4所示，该车辆信息采集方法主要包括以下流程：
S401、以无线方式从车载终端获取目标车辆信息；
S402、对获取的所述目标车辆信息进行解析处理，得到原始车辆信息，所述目标车辆信息具有比所述原始车辆信息更小的数据传输量；
S403、对所述原始车辆信息进行显示。
其中，步骤S401可以以蓝牙通信方式从车载终端获取目标车辆信息，可选的，可以定时接收车载终端发送的Ble Advertising，其中携带目标车辆信息。
步骤S402主要用于从目标车辆信息中恢复出原始车辆信息，其解析规则与车载终端的处理规则相适配，假设车载终端以归一化处理和编码的方式将原始车辆信息处理成目标车辆信息的，则步骤S402按照与编码规则对应的解码规则对目标车辆信息进行解码，得到中间车辆信息，再按照与归一化规则对应的反归一化规则对中间车辆信息进行反归一化处理，恢复出原始车辆信息。
假设车载终端分对每种车辆信息进行归一化处理和编码后得到一个字节的目标车辆信息。则步骤S402可以分别对每一个字节的目标车辆信息按照对应的预设解码规则进行解码，解析出一种中间车辆信息，再按照对应的反归一化规则将该中间车辆信息还原成对应的原始车辆信息。下面举例说明：
假设车载终端将油位信息X转换成编码0x01，则步骤S402按照如下与编码规则一对应的解码规则进行解码：0x00，表示剩余油位百分比在0-10％；0x01，表示油位百分比在10％-30％；0x02，表示油位百分比在30％-60％；0x04，表示油位百分比在60％-80％；0x08，表示油位百分比在80％-100％；假设步骤S402按照上述的解码规则，从编码0x01解析出油位百分比Y在
10％-30％，再根据车辆油箱容量L，和油位百分比Y，计算油位信息：X＝L*Y，步骤S403对计算出的油位信息X进行显示。
