After obtaining the respective mileage number of multiple continuous history mileage sections and history unit mileage power consumption values, VCU, that is, root
According to the respective mileage number of multiple continuous history mileage section and history unit mileage power consumption values, to determine multiple continuous
Mean unit mileage power consumption values in history mileage section, the mean unit mileage power consumption values characterize automobile multiple continuous
The power consumption values of unit mileage in total mileage section of history mileage section.
As a kind of conventional calculation, which can be according to calculating multiple continuous
It is average single to generate this for total power consumption values in history mileage section, divided by total mileage number in multiple continuous history mileage section
Position mileage power consumption values.As an implementation, the another kind that the embodiment of the present invention is provided generates the mean unit mileage energy
The mode of consumption value is：With each respective mileage number of history mileage section, as in the respective history unit of each history mileage section
The weight parameter of journey power consumption values, to generate the mean unit mileage power consumption values in multiple continuous history mileage section.Specifically,
Referring to Fig. 2, Fig. 2 is a kind of schematic flow chart of the sub-step of step S300 in Fig. 1, and in embodiments of the present invention, step
S300 includes following sub-step：
Sub-step S330, according to the total mileage number of multiple continuous history mileage sections and each history mileage section it is respective in
Number of passes determines each respective weight parameter of history mileage section.
It after each respective mileage number of history mileage section, that is, is calculated in multiple continuous history mileage sections obtaining automobile
The total mileage number of multiple continuous history mileage section is obtained, and according to each respective mileage number of history mileage section and is calculated
The total mileage number of multiple continuous history mileage section obtained, calculates each respective weight parameter of history mileage section, wherein
The mileage number that each respective weight parameter of history mileage section characterizes each history mileage section accounts for multiple continuous history mileage

From the respective history unit mileage power consumption values of weight parameter and each history mileage section, generate in multiple continuous history
Mean unit mileage power consumption values in journey section.
Specifically, referring to Fig. 3, Fig. 3 shows a kind of calculating schematic diagram of mean unit mileage power consumption values, it is assumed that current
VCU has got 3 continuous history mileage section AB, BC and CD, and mileage section AD characterizes AB, BC and CD this 3 and continuously goes through
The sum of history mileage section, and these three respective mileage numbers of history mileage section are respectively 1 kilometer, 2 kilometers and 2 kilometers, these three are gone through
The respective mean unit mileage power consumption values of history mileage section be 0.2kwh/km, 0.3kwh/km and 0.4kwh/km, then AB sections
Weight parameter be then the weight parameter that 1/5, BC sections of weight parameter is 2/5, CD sections be 2/5, it is assumed that multiple companies are characterized in p
Mean unit mileage power consumption values in continuous history mileage section, then p=0.2kwh/km*1/5+0.3kwh/km*2/5+
0.4kwh/km*2/5, i.e. p=0.32kwh/km, that is to say, that in this section of mileage section of AD, in the mean unit of automobile
Journey power consumption values are 0.32kwh/km.
For electric vehicle in normal traveling, unit mileage power consumption values tend not to change dramatically, if multiple continuous
History mileage section in change dramatically has occurred, then illustrate that exception has occurred in the data record of VCU, that is to say, that if multiple companies

In multiple continuous history mileage sections that VCU is obtained, according to the respective history unit of each history mileage section
Mileage power consumption values determine the mileage section of all energy consumption exceptions.Wherein, the mileage section of all energy consumption exceptions includes multiple continuous
History unit mileage power consumption values are less than the first preset value or all history mileage sections more than the second preset value in history mileage section.
For example, in the calculating schematic diagram of mean unit mileage power consumption values as shown in Figure 3, it is assumed that the first preset value is
0.25kwh/km, the second preset value are 0.5kwh/km, then history mileage section AB is the mileage section of energy consumption exception, at this time
The mileage section of all energy consumption exceptions includes only AB；If the first preset value of hypothesis is 0.31kwh/km, the second preset value is
0.38kwh/km, then history mileage section AB and CD is the mileage section of energy consumption exception, at this time the mileage section of all energy consumption exceptions
Contain AB and CD.

Position mileage power consumption values, the respective new history unit mileage power consumption values of mileage section as all energy consumptions exception.
After the mileage section for determining all energy consumption exceptions according to sub-step S310, i.e., with preset average energy consumption initial value
The respective history unit mileage power consumption values of mileage section of all energy consumption exceptions are replaced, the mileage section as all energy consumptions exception is respectively
New history unit mileage power consumption values so that the mean unit mileage power consumption values calculated by sub-step S340 are more
Reliably.
For example, being 0.25kwh/km in above-mentioned the first preset value of hypothesis, the second preset value is the reality of 0.5kwh/km
In example, it is assumed that preset average energy consumption initial value is 0.35kwh/km, then in the history unit of the mileage section AB after replacement
Journey power consumption values are 0.35kwh/km.Hereafter, i.e., with the history unit mileage power consumption values of the mileage section AB after replacement, as
History unit mileage power consumption values used in mean unit mileage power consumption values are generated in sub-step S340, for example, p=at this time
0.35kwh/km*1/5+0.3kwh/km*2/5+0.4kwh/km*2/5, i.e. p=0.35kwh/km.
Based on above-mentioned design, a kind of mileage computational methods that the embodiment of the present invention is provided, by multiple companies
The history unit mileage power consumption values of the mileage section of all energy consumption exceptions are replaced in continuous history mileage section, to correct according to every
