本公开附加的方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本公开的实践了解到。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
下面参考附图描述本公开实施例的电动车辆续驶里程确定方法和装置。
图1是本公开一示例性实施例提供的电动车辆续驶里程确定方法的流程图。该方法可以应用于车辆，例如车辆内部的控制部件，如车身控制器、整车控制器、电池管理系统等等。如图1所示，该方法可以包括S101至S105。
S101，在电动车辆上电时，计算电动车辆的当前虚拟SOE值。
示例性地，虚拟SOE值是根据电动车辆的电池剩余电量百分比、电池健康度、电池电量理论值和电池包的电芯温度系数计算得到的SOE值，具体计算方式如下：
虚拟SOE＝SOC*SOH*电池包的电芯温度系数*电池电量理论值
其中，SOC(state of charge)为电池剩余电量百分比；SOH(state of health)为电池健康度，即电池当前的容量与出厂容量的百分比。
S102，比较当前虚拟SOE值与存储虚拟SOE值，其中，存储虚拟SOE值为电动车辆上次下电前存储的虚拟SOE值。
其中，电动车辆每次下电前，会将电动车辆的当前实际剩余里程、平均能耗和虚拟SOE值，存储到控制器底层中，在电动车辆重新上电时调用上次下电前存储的虚拟SOE值，根据当前虚拟SOE值与存储虚拟SOE值的比较结果，确定初始显示续航里程。
S103，若当前虚拟SOE值与存储虚拟SOE值之差超出预设的差值范围，则根据当前虚拟SOE值确定初始显示续驶里程。
其中，上述的超出预设的差值范围是指：大于该差值范围的上限值的情况以及小于该差值范围的下限值的情况。
若当前虚拟SOE值与存储虚拟SOE值之差超出预设的差值范围，说明电动车辆当前状态与下电前状态差别较大，选择用当前虚拟SOE值来确定初始显示续驶里程，可以避免因调用电动车辆上次下电前存储的实际剩余里程造成的误差，使初始显示续驶里程更为准确。
S104，若当前虚拟SOE值与存储虚拟SOE值之差处于该差值范围内，则将电动车辆上次下电前存储的实际剩余里程确定为初始显示续驶里程。
其中，上述的处于该差值范围是指：小于或等于该差值范围的上限值且大于或等于 该差值范围的下限值的情况。
若当前虚拟SOE值与存储虚拟SOE值之差处于该差值范围，说明电动车辆当前状态与下电前状态基本一致，将电动车辆上次下电前存储的实际剩余里程确定为初始显示续驶里程，可以满足初始显示续驶里程的准确性要求。
S105，显示初始显示续驶里程。
示例地，可以通过车内的显示部件进行显示，该显示部件包括但不限于：仪表盘、行车电脑的显示屏、与车辆进行通信的其他外部电子设备的显示屏等等。
通过上述技术方案，在电动车辆续驶里程确定的过程中，在电动车辆上电后，对初始显示续驶里程进行了修正。具体为，当本次上电计算的当前虚拟SOE值与上次下电前存储的虚拟SOE值的差值超出预设的差值范围，则根据当前虚拟SOE值确定初始显示续驶里程，否则将电动车辆上次下电前存储的实际剩余里程确定为初始显示续驶里程。如此，在确定初始显示续驶里程的过程中引入预设的差值范围，根据电动车辆状态给定准确的值，将历史记录和实时计算结果有机的结合在一起，能够提高初始显示续驶里程的准确性，提升用户的电动车辆使用的体验感。
为了让用户更好的规划好行程和路线，避免因电量耗尽造成的不便，提升用户体验感，在电动车辆使用过程中，平均能耗同样被用作用户出行需参考的重要参数。
图2是本公开另一示例性实施例提供的电动车辆续驶里程确定方法的流程图。如图2所示，该方法可以包括S201至S207。
S201，在电动车辆上电时，计算电动车辆的当前虚拟SOE值。
S202，比较当前虚拟SOE值与存储虚拟SOE值。
若当前虚拟SOE值与存储虚拟SOE值之差超出预设的差值范围，则执行S203和S204。
S203，将电动车辆的目标能耗确定为初始显示能耗。
示例性地，目标能耗为动力电池的电量理论值与电动车辆最大续驶里程之比，即，目标能耗＝动力电池的电量理论值/电动车辆最大续驶里程，可通过同车型电动车辆实验结果进行设置。
S204，根据当前虚拟SOE值确定初始显示续驶里程。

S206，将电动车辆上次下电前存储的平均能耗确定为初始显示能耗。
S207，显示初始显示续驶里程和初始显示能耗。
对于本领域技术人员公知的，平均能耗的计算方式有多种。在本公开提供的示例性实施方式中，为了提高平均能耗计算的准确性，平均能耗可以采用n个(例如，n＝30)单位片段平均能耗迭代的方法来计算，每个单位片段距离为Skm，计算在Skm行驶所消耗的能量为SumEDrv(电池实际放电功率积分值)，行驶消耗能量SumEDrv和距离Skm之比，确定为此片段路段的计算行驶平均能耗AvgE n，单位kw·h/km，将电动车辆行驶的平均能耗AvgE写成迭代形式，即：
AvgE＝(a 1*AvgE 1+a 2*AvgE 2+…+a n-1*AvgE n-1+a n*AvgE n)/n
a 1、a 2、……、a n-1、a n参数为各片段平均能耗的权重系数，其中，距离当前越远的片段，其权重越低，权重系数是通过实车验证标定的值，其中a 1+a 2+…+a n-1+a n＝n。
根据上述技术方案，将平均能耗设置为用户出行需参考的重要参数。在电动车辆使用时，根据本次上电计算的当前虚拟SOE值与上次下电前存储的虚拟SOE值是否超出预设的差值范围，确定初始显示能耗，其中引入目标能耗，避免因存储的平均能耗和实际平均能耗差距过大导致的初始显示能耗不准的问题，能够提高初始显示能耗的准确性，进一步提升用户的电动车辆使用的体验感。
在一种可能的实施方式中，根据当前虚拟SOE值确定初始显示续驶里程，可以包括：根据当前虚拟SOE值与电动车辆的目标能耗之比，确定初始显示续驶里程。例如，初始显示续驶里程＝当前虚拟SOE值/目标能耗。
在电动车辆的实际使用中，除了初始显示里程和初始显示能耗之外，电动车辆在静止、行驶、充电状态下显示的续驶里程同样对用户出行有重要的参考意义。
图3是本公开另一示例性实施例提供的电动车辆续驶里程确定方法的流程图。如图3所示，在电动车辆上电后，该方法还可以包括：
S301，在电动车辆处于静止状态的过程中，每当电动车辆的动力电池的SOC值下降到满足第一续驶里程计算条件时，根据当前显示的续驶里程和动力电池的当前SOC值，确定续驶里程下降系数，并根据动力电池的SOC下降值与续驶里程下降系数，确定续驶里程下降值，其中，该SOC下降值为动力电池在本次满足第一续驶里程计算条件时的SOC值相比于上次满足第一续驶里程计算条件时的SOC值的下降值。
示例性地，上述的第一续驶里程计算条件可以为：动力电池的SOC值下降第一预设 比例，该第一预设比例例如为0.05％，即在SOC值每下降0.05％时，车辆在静止状态下的续驶里程下降系数更新一次，并更新显示的续驶里程，确保用户能够实时获取更新的续驶里程。在其他实施方式中，上述的第一续驶里程计算条件也可以为：动力电池的SOC值下降预设阈值。
示例性地，根据当前显示的续驶里程和动力电池的当前SOC值，确定续驶里程下降系数，可以包括：根据当前显示的续驶里程和动力电池的当前SOC值之比，确定续驶里程下降系数。例如，续驶里程下降系数＝当前显示的续驶里程/当前SOC值。
示例性地，根据动力电池的SOC下降值与续驶里程下降系数，确定续驶里程下降值，可以包括：根据动力电池的SOC下降值与续驶里程下降系数之积，确定续驶里程下降值。例如，续驶里程下降值＝SOC下降值×续驶里程下降系数。
S302，根据当前显示的续驶里程与续驶里程下降值之差，确定更新的续驶里程。示例性地，更新的续驶里程＝当前显示的续驶里程-续驶里程下降值。
S303，显示更新的续驶里程，以替换之前显示的续驶里程。
根据上述技术方案，在电动车辆处于静止状态的过程中，对续驶里程进行滤波计算，根据当前显示的续驶里程和动力电池的当前SOC值之比实时确定下降系数，用于确定更新的续驶里程值，能够提高用户获取的续驶里程的准确性，以进一步提升用户的电动车辆使用的体验感。
图4是本公开另一示例性实施例提供的电动车辆续驶里程确定方法的流程图。如图4所示，在电动车辆上电后，该方法还可以包括：
S401，在电动车辆处于行驶过程中，若满足第一续驶里程滤波条件，则每当电动车辆的行驶里程变化到满足第二续驶里程计算条件时，根据当前显示的续驶里程与当前实际剩余里程之间的差值、以及电动车辆的动力电池的当前SOC值，通过查表确定与当前SOC值和该差值对应的续驶里程下降系数，其中，该当前实际剩余里程是基于当前虚拟SOE值和当前平均能耗实时确定的；根据电动车辆的行驶里程变化值与续驶里程下降系数，确定续驶里程下降值，其中，该行驶里程变化值为电动车辆在本次满足第二续驶里程计算条件时的行驶里程相比于上次满足第二续驶里程计算条件时的行驶里程的变化值。
示例性地，上述的第一续驶里程滤波条件可以包括：
动力电池的当前SOC值小于预设的SOC阈值；或者，
动力电池的当前SOC值大于或等于SOC阈值、且当前显示的续驶里程大于当前实 际剩余里程；或者，
动力电池的当前SOC值大于或等于SOC阈值、且动力电池的SOC值在下降。
示例性地，上述的第二续驶里程计算条件可以为：行驶里程增加预设距离。例如，该预设距离可以设置为1km，即车辆在行驶状态下，每行驶1km，根据当前显示的续驶里程与当前实际剩余里程之间的差值、以及电动车辆的动力电池的当前SOC值，通过查表确定出与当前SOC值和该差值对应的续驶里程下降系数，并据此更新显示的续驶里程，确保用户能够实时获取更新的续驶里程。在其他实施方式中，上述的第二续驶里程计算条件也可以为：行驶里程增加第二预设比例。
示例性地，车辆的实际剩余里程基于车辆的虚拟SOE值和平均能耗来确定。例如，实际剩余里程＝虚拟SOE值/平均能耗。
示例性地，因为不同驾驶习惯和路况的复杂性，所以续驶里程是会变化的，可能会行驶0.5km，显示的续驶里程就下降1km，反之可能行驶1.5km，显示的续驶里程才会下降1km。可以预先通过实验数据，预先标定出数据表，该数据表中记录了显示的续驶里程与实际剩余里程之间的差值、动力电池的SOC值以及续驶里程下降系数三者之间的对应关系。如此，在S401中，可以根据当前显示的续驶里程与当前实际剩余里程之间的差值、以及电动车辆的动力电池的当前SOC值，通过查询该数据表，确定出与当前SOC值和该差值对应的续驶里程下降系数。
在确定出续驶里程下降系数之后，根据电动车辆的行驶里程变化值与续驶里程下降系数，确定续驶里程下降值。示例性地，根据电动车辆的行驶里程变化值与续驶里程下降系数之比，确定续驶里程下降值。例如，续驶里程下降值＝行驶里程变化值/续驶里程下降系数。
S402，根据当前显示的续驶里程与续驶里程下降值之差，确定更新的续驶里程。示例性地，更新的续驶里程＝当前显示的续驶里程-续驶里程下降值。
S403，显示更新的续驶里程，以替换之前显示的续驶里程。
根据上述技术方案，在电动车辆处于行驶状态的过程中，对续驶里程进行滤波计算，在满足第一续驶里程滤波条件的情况下，根据当前显示的续驶里程与当前实际剩余里程之间的差值、以及电动车辆的动力电池的当前SOC值，通过查表实时确定续驶里程下降系数，并据此确定更新的续驶里程值，能够提高用户获取的续驶里程的准确性，进一步提升用户电动车辆使用的体验感。
在一种可能的实施方式中，如图4所示，在电动车辆上电后，该方法还可以包括：
S404，在电动车辆处于行驶过程中，若满足第二续驶里程滤波条件，则每隔第一预设时间，将当前实际剩余里程确定为更新的续驶里程，之后，执行步骤S403。
其中，第二续驶里程滤波条件可以包括：动力电池的当前SOC值大于或等于SOC阈值、动力电池的SOC值在上升、且当前显示的续驶里程小于当前实际剩余里程。示例性地，当电动车辆动力电池的温度上升或电动车辆滑行导致能量回收，此时动力电动的SOC值会上升。
示例性地，该第一预设时间可设置为100ms，即电动车辆处于行驶状态下，在满足第二续驶里程滤波条件的情况下，时间间隔每达到100ms时，显示的续驶里程被更新为当前实际剩余里程，确保用户能够实时获取更新的续驶里程。
根据上述技术方案，在电动车辆处于行驶状态的过程中，对续驶里程进行滤波计算，在满足第二续驶里程滤波条件的情况下，每隔第一预设时间，将当前实际剩余里程确定为更新的续驶里程，避免在动力电动的SOC值上升的情况下，因更新的续驶里程不准，导致用户无法更好的规划行程的问题。
图5是本公开另一示例性实施例提供的电动车辆续驶里程确定方法的流程图。如图5所示，在电动车辆上电后，该方法还可以包括：
S501，在电动车辆处于充电的过程中，若满足第三续驶里程滤波条件，则每隔第二预设时间，根据目标比例以及动力电池在第二预设时间内的SOC变化值，确定续航里程增加值，其中，目标比例为电动车辆最大的续驶里程与当前显示的续驶里程的差值和动力电池满电量时的SOC值与动力电池的当前SOC值的差值之比。即，目标比例＝(电动车辆最大的续驶里程-当前显示的续驶里程)/(动力电池满电量时的SOC值-动力电池的当前SOC值)。
示例性地，第三续驶里程滤波条件可以包括：动力电池的当前SOC值未达到动力电池满电量时的SOC值，或者，当前显示的续驶里程未达到车辆最大的续驶里程。
示例性地，第二预设时间的数值可与第一预设时间的数值相同，也可不同。例如，第二预设时间可设置为100ms，即电动车辆处于行驶状态下，在满足第三续驶里程滤波条件的情况下，时间间隔每达到100ms时，根据目标比例以及动力电池在该100ms内的SOC变化值之积，确定续航里程增加值，并据此确定更新的续驶里程，确保用户能够实时获取更新的续驶里程。
示例性地，根据目标比例以及动力电池在第二预设时间内的SOC变化值，确定续航里程增加值，可以包括：根据目标比例以及动力电池在第二预设时间内的SOC变化值之积，确定续航里程增加值。例如，续航里程增加值＝SOC变化值×目标比例。
S502，根据当前显示的续驶里程与续驶里程增加值之和，确定更新的续驶里程。示例性地，更新的续驶里程＝当前显示的续驶里程+续驶里程增加值。
S503，显示更新的续驶里程，以替换之前显示的续驶里程。
根据上述技术方案，在电动车辆处于充电状态的过程中，对续驶里程进行滤波计算，在满足第三滤波条件的情况下，进行实时更新，根据目标比例以及动力电池在第二预设时间内的SOC变化值之积，确定续驶里程增加值，并据此确定更新的续驶里程。如此，在充电时能够实时获取更新的续驶里程，提升用户电动车辆使用的体验感。
