为了更清楚地说明本申请实施例中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是本申请实施例提供的一种车辆里程计算方法的示意流程图；
图2是本申请实施例提供的一种车辆里程计算系统的示意性框图；
图3是本申请实施例提供的一种车辆里程计算终端设备的结构示意图。
 本发明的实施方式
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、技术之类的具体细节，以便透彻理解本申请实施例。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的系统、装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
为了说明本申请所述的技术方案，下面通过具体实施例来进行说明。
参照图1，本申请实施例提供了一种车辆里程计算方法，包括：
步骤S101，获取车辆的CAN数据，并根据所述CAN数据确定所述车辆的第一里程。
在本申请实施例中，车辆上设置有车载终端，车载终端与车辆自身的CAN总线连接。
作为本申请实施例的一种实施方式，司机通过按键或其他方式触发车载终端，指示车辆处于载客状态，车载终端通过CAN总线连接获取CAN数据，并将CAN数据发送给后台终端，即后台终端远程获取车辆为载客状态时的CAN数据，同理，当车辆到达目的地时，司机通过按键或其他方式触发车载终端，指示车辆载客过程结束，车载终端停止向后台终端发送CAN数据，后台终端可以记录本次载客的载客行驶时间。
CAN数据中包括车辆的实时车速，后台终端设定时间间隔，从车辆处于载客状态时起，后台终端根据实时车速进行积分运算，计算出每个时间间隔内车辆行驶的距离，将计算出的距离累加，就可以实时计算出车辆在本次载客过程中的载客里程，当车辆载客过程结束时，计算得到的载客里程即为第一里程。
作为本申请实施例的另一种实施方式，车载终端保存载客过程中的CAN数据，当车辆载客过程结束后，车载终端将载客过程中的CAN数据发送至后台终端，后台终端根据获取的CAN数据计算第一里程。
步骤S102，获取所述车辆的GPS数据，并根据所述GPS数据确定所述车辆的第二里程。
在本申请实施例中，上述车载终端中设置有GPS定位装置，或者车载终端与车辆上的GPS定位装置连接。
作为本申请实施例的一种实施方式，当车辆处于载客状态时，车载终端获取车辆的GPS数据并发送给后台终端，即后台终端远程获取车辆为载客状态时的GPS数据，当车辆到达目的地时，车载终端停止向后台终端发送GPS数据。
GPS数据中包括车辆的实时位置，后台终端设定时间间隔，从车辆处于载客状态时起，后台终端根据每个时间间隔的初始时刻位置和最终时刻位置，计算出每个时间间隔内车辆的距离变化值，将各个距离变化值累加，就可以实时计算出车辆在本次载客过程中载客里程，当车辆载客过程结束时，计算得到的载客里程即为第二里程。
作为本申请实施例的另一中实施方式，车载终端保存载客过程中的GPS数据，当车辆载客过程结束后，车载终端将载客过程中的GPS数据发送至后台终端，后台终端根据获取的GPS数据计算第二里程。
步骤S103，若所述第一里程与所述第二里程的差值的绝对值小于预设阈值，则将所述第一里程作为所述车辆的计费里程。
在本申请实施例中，后台终端将计算出的第一里程和第二里程进行比较，当第一里程和第二里程的差值的绝对值小于后台终端设定的阈值时，认定第一里程和第二里程数据准确，同时也表明CAN数据和GPS数据正常。而CAN数据不容易人为更改，因此，后台终端将第一里程作为车辆的计费里程。
后台终端还可以将计费里程发送给车载终端，以使车载终端对计费里程进行显示，或者使车载终端根据计费里程计算乘车费用。
这里的可以是第一里程与第二里程的差值，也可以是上述差值与第一里程之比，采用不同的差值计算方式，设定的阈值也不相同。
从以上描述可以看出，本申请实施例通过获取车辆自身的CAN数据计算车辆的第一里程，并利用GPS数据计算车辆的第二里程，可以辅助判断第一里程是否准确，当第一里程和第二里程的差值符合要求时，确定第一里程准确，将第一里程作为计费里程，大大增加了司机里程作弊的难度，能够有效避免给乘客带来经济损失。
在一实施例中，所述车辆里程计算方法还包括：
若所述第一里程与所述第二里程的差值的绝对值大于预设阈值，则确定所述车辆的行驶轨迹，并根据所述行驶轨迹确定所述车辆的行驶里程；
若所述第一里程小于所述行驶里程，则将所述第一里程作为所述车辆的计费里程。
在本申请实施例中，若第一里程与第二里程的差值的绝对值大于后台终端设定的阈值，表明第一里程和第二里程中有一组数据不准确。
后台终端再通过车载终端获取车辆的行驶轨迹，根据行驶轨迹估算出车辆的行驶里程，将第一里程与行驶里程进行对比。正常情况下根据CAN数据确定的第一里程应小于根据行驶轨迹确定的行驶里程，若第一里程小于行驶里程，则认定第一里程的数据准确，将第一里程作为车辆的计费里程。
在一实施例中，所述确定所述车辆的行驶轨迹，包括：
当所述车辆为载客状态时，获取所述车辆的实时位置，并根据所述实时位置确定所述车辆的行驶轨迹。
在本申请实施例中，在载客时间段内，后台终端通过车载终端获取车辆在各个预设行驶时刻的位置，例如，每隔15秒获取车辆当前时刻的位置点，同时识别车辆的拐弯动作，当车辆进行拐外时立刻获取车辆当前时刻的位置点，当车辆到达目的地后，后台终端执行设置的软件程序，根据离散的位置点模拟出车辆的行驶轨迹，确定行驶轨迹对应的实际路程，并将其作为行驶里程，用于判断第一里程的数据是否准确。
在一实施例中，所述车辆里程计算方法还包括：
若所述第一里程小于所述行驶里程，则将第二里程异常信息发送至监控终端。
在本申请实施例中，若第一里程小于行驶里程，则表明第一里程数据准确，而第二里程数据不准确，相应的也就表明CAN数据正常，GPS数据异常。后台终端将第二里程异常的信息发送至监控终端，提醒后台人员对车载终端上的GPS定位装置或车辆上的GPS定位装置进行故障检查。这里的监控终端是指由后台人员操控的终端设备，具体可以是计算机或手机等终端设备。
在一实施例中，所述车辆里程计算方法还包括：
若所述第一里程大于所述行驶里程，则将所述第二里程作为所述车辆的计费里程。
在本申请实施例中，若第一里程大于行驶里程，则表明第一里程数据不准确，第二里程数据准确，因此将第二里程作为车辆的计费里程，避免给乘客带来经济损失。
在一实施例中，所述车辆里程计算方法还包括：
若所述第一里程大于所述行驶里程，则将第一里程异常信息发送至监控终端。
在本申请实施例中，若第一里程大于行驶里程，则表明第一里程数据不准确，而第二里程数据准确，相应的也就表明CAN数据异常，GPS数据正常。后台终端将第一里程异常的信息发送至监控终端，提醒后台人员对车载终端和车辆的CAN总线进行故障检查，进而确定是设备故障还是司机作弊。
在一实施例中，所述CAN数据包括所述车辆的实时车速；
所述根据所述CAN数据确定所述车辆的第一里程，包括：
当所述车辆为载客状态时，根据所述实时车速和第一预设时间间隔，积分计算出所述车辆在第一预设时间间隔内的载客里程；
将载客时间段内的载客里程之和作为第一里程。
在本申请实施例中，后台终端设定时间间隔，从车辆处于载客状态时起，后台终端根据实时车速进行积分运算，计算出每个时间间隔内车辆行驶的距离，例如，根据实时车速每20毫秒计算一次距离，将计算出的距离累加，就可以实时计算出车辆在本次载客过程中的载客里程，当车辆载客过程结束时，计算得到的载客里程即为第一里程。
在一实施例中，所述根据所述GPS数据确定所述车辆的第二里程，包括：
当所述车辆为载客状态时，获取所述GPS数据中的实时位置，根据所述实时位置确定所述车辆在第二预设时间间隔内的距离变化值；
将载客时间段内的距离变化值之和作为第二里程。
在本申请实施例中，后台终端设定时间间隔，从车辆处于载客状态时起，后台终端根据每个时间间隔的初始时刻位置和最终时刻位置，计算出每个时间间隔内车辆的距离变化值，将各个距离变化值累加，就可以实时计算出车辆在本次载客过程中载客里程，当车辆载客过程结束时，计算得到的载客里程即为第二里程。
在一实施例中，所述车辆里程计算方法还包括：
根据所述计费里程计算乘车费用，并将所述乘车费用发送至所述车辆。
在本申请实施例中，后台终端设置有乘车费用计算公式，在确定计费里程后，将计费里程代入公式计算得到乘车费用，并将乘车费用发送至车辆，减少了车载终端的处理过程，能够有效增加司机作弊的难度。
