obtaining a vehicle urea consumption verification model from a server, wherein the vehicle urea consumption verification model takes a vehicle urea fuel consumption ratio (hundred kilometers of urea consumption/hundred kilometers of fuel consumption) as a verification parameter, and the calculation process of the verification parameter is as follows:
relevant parameters such as urea cyclic injection amount, vehicle speed, fuel cyclic injection amount, engine speed, clutch signals and the like in the running process of the vehicle are collected through TBOX, hundred-kilometer urea consumption and hundred-kilometer fuel consumption are calculated by using recent 500-kilometer data every 5 minutes, and then the ratio of the two is calculated. The calculation formula is as follows:
accumulating the running mileage (kilometer) of the interval to sigma current speed (unit m/s) of the vehicle and collecting the interval/1000;
1 kilometer interval urea accumulated consumption ═ sigma current urea injection amount (unit second) × collection interval;
in actual calculation, urea consumption calculation formulas of the vehicles are different according to different accumulated driving mileage of the vehicles, specifically:
when the vehicle accumulated driving mileage is more than 500 kilometers:
the urea consumption of 100 kilometers is equal to the urea accumulative consumption value/5 of the section with 500 kilometers of the latest section accumulative driving mileage;
the endurance mileage is equal to the current urea liquid level value/100 kilometers of urea consumption;
when the vehicle accumulated driving range is less than 500 km:
the urea consumption of 100 kilometers is the total urea consumption in the total interval/the total driving mileage in the total interval;
the endurance mileage is equal to the current urea liquid level value/100 kilometers of urea consumption;
determining that the urea fuel consumption of the specified vehicle type is 3% -7% of the normal range based on expert experience, in order to further refine the range value, extracting the latest 2000 kilometer data collected by 100 vehicles of the vehicle type in history, calculating the latest 500 kilometer urea fuel consumption ratio every 5 minutes by the calculation formula to obtain the latest 2000 kilometer urea fuel consumption ratio distribution of 100 vehicles, wherein nearly 3 thousands of data points are obtained, after eliminating abnormal values, clustering is carried out on the 3 thousands of data points by using a clustering method, the data is found to be best in 7 types through verification, wherein the group with the most 3 data points accounts for 87% of the total data points, after combining the group data with the most 3 data points, the upper and lower limit ranges of the data are calculated by using a box diagram algorithm, and finally the urea fuel consumption of the vehicle type is determined to be 3.3% -7.1% of the normal range by using big data, namely, the range of the verification parameter threshold is 3.3% -7.1%.
When a verification request signal is received, because the verification period is long, urea fuel consumption ratio monitoring is automatically conducted in a verification model from a server, when the urea fuel consumption ratio is within a configured normal interval range during the designated time of vehicle operation or during the designated mileage process, the maintenance is considered to be effective, and a maintenance result is returned to the mobile terminal.
