100 km urea consumption = interval urea cumulative consumption value/5 of 500 km of the nearest interval cumulative driving mileage;
range = current urea level value/100 km urea consumption;
when the accumulated driving distance of the vehicle is less than 500 km:
100 km urea consumption = total interval urea cumulative consumption/total interval cumulative mileage;
range = current urea level value/100 km urea consumption;
determining that the range of the urea fuel consumption ratio normal interval of a specified vehicle model is 3% -7% based on expert experience, for further accurate value of the range, extracting the latest 2000 km data collected by the vehicle history of 100 vehicles of the vehicle model, calculating the latest 500 km urea fuel consumption ratio every 5 minutes through the calculation formula to obtain the latest 2000 km urea fuel consumption ratio distribution of 100 vehicles, totally closing 3 tens of thousands of data points, clustering 3 tens of thousands of data points by using a clustering method after abnormal values are removed, verifying to find that the data are clustered into 7 types with the best effect, wherein the group with the largest 3 data points occupies 87% of the total data points, merging the combined data with the largest 3 data points, calculating the upper and lower limit intervals of the data by using a box diagram algorithm, and finally determining that the range of the urea fuel consumption ratio normal interval of the vehicle model is 3.3% -7.1% by large data, namely, the threshold range of verification parameters is 3.3% -7.1%.
When a verification request signal is received, as the verification period is longer, the verification model is automatically imported from the server to monitor the urea fuel consumption ratio, when the vehicle operates in a specified time or in a specified mileage process, the urea fuel consumption ratio is in a configured normal interval range, namely, the maintenance is considered to be effective, and a maintenance result is returned to the mobile terminal.
