Claim:
A method for quickly calculating mileage, comprising: A. receiving report data from a vehicular terminal and updating a data center ( 400 ) according to the report data; wherein the report data includes a vehicle number, a report time and a total mileage value of a vehicle corresponding to the vehicle number during the report time; B. receiving an inquiry request which includes the vehicle number, a first time point and a second time point which are requested to inquire, wherein the first time point is earlier than the second time point; C. screening out a first data set having a report time within a range from the first time point to the second time point from the data center ( 400 ), wherein the first data set includes the vehicle number, the report time and the total mileage value; D. sorting the first data set obtained in the step C in a descending order in accordance with the report time, and extracting the first data of the sorted first data set in the descending order for respective vehicle number which is requested to inquire to obtain a second data set; E. sorting the first data set obtained in the step C in an ascending order in accordance with the report time, and extracting a first data of the sorted first data set in the ascending order for the respective vehicle number which is requested to inquire to obtain a third data set; F. screening and filtering the third data set obtained in the step E and selecting a first total mileage value for the vehicle number which is requested to inquire, and screening and filtering the second data set obtained in the step D and selecting a second total mileage value for the vehicle number which is requested to inquire, wherein a time point to which the first total mileage value corresponds is larger than or equal to and further proximate to the first time point, and a time point to which the second total mileage value corresponds is smaller than or equal to and further proximate to the second time point; G. obtaining a running mileage L for the vehicle number requested to inquire from the first time point to the second time point by subtracting the first total mileage value from the second total mileage value; and H. returning the running mileage L to a user requesting to inquire.
