According to later, remaining urea level data are successively denoted as D1, D2, D3..Dk, Dk+1 ... Dn, wherein D1 is denoted as being first
Starting point, k are positive integer；
Successively judge whether Dk+1-Dk > 10%；
If Dk+1-Dk > 10%, Dk are as first end point；
Compare the size of Dk+1 and DK+2；
As Dk+1 > DK+2, judge whether DK+1-DK+2 < 2%；
If DK+1-DK+2 < 2%, Dk+1 are as second starting point；
If DK+1-DK+2 >=2%, Dk+2 are as second starting point；
As DK+1=DK+2, then Dk+2 is as second starting point；
When DK+1 < DK+2, Dk+1 as second starting point or Dk+2 as second starting point when, by k plus judging after 1
Whether obtained value is n；
If obtained value is n, Dn is the last one end point；
Each end point is subtracted each other with starting point, then adds up and obtains heavy truck in the urea consumption of the period；
If obtained value is not n, continues next group and judge whether DK+1-DK > 10%, until obtaining the last one terminates
Point.
