The working condition of row situation and exhaust gas aftertreatment system once monitoring that tail gas is exceeded, can send warning at once, meanwhile, OBD meetings
Fault message (i.e. error code) is preserved, maintenance personal can quickly and accurately determine property and the position of failure according to error code.
Since the OBD system of different production firms is incompatible, in order to seek unity of standard, 1988, american car engineer
Association SAE has formulated OBD-II standards.Communication interface of the OBD interfaces as vehicle-mounted monitoring system, except OBD interfaces can be passed through
Read failure code is used outside for repairing, and OBD interfaces can also provide the various floor datas of vehicle, for example, except vehicle instrument
Outside the data that table is shown, what the actual data recorded in car running computer will be more is more, and every engine load rate, battery are electric
The data such as pressure, air-fuel ratio, throttle opening all have record in systems.

Step S201:Stop after the vehicle traveling a period of time for having filled it up with oil, in the process of moving, according to preset time week
Phase Xun Huan reads engine speed data.Specifically, it is necessary first to (judge the standard that fuel tank fills it up with to gas station's top off
For automatic rifle of jumping is top off)；Then stop after vehicle being travelled a period of time (it is recommended that traveling more than 20km)；Most
Interface is diagnosed by OBDII afterwards and gets real-time engine speed data.In the present embodiment, preset period of time (obtains
The frequency of pick-up engine speed data) it is 1 second/time.
It should be noted that vehicle oil consumption is in addition to related with rotating speed, it is also related with engine load rate.But part vehicle
Type, the vehicle of manufacture sale particularly before 2006, poor for the suitability of OBD boxes, Some vehicles are for basic OBD
Information (such as charge flow rate, admission pressure, engine load rate) is also obtained less than, the only speed that can get, rotating speed, cold
But a small amount of information such as liquid temperature degree.Under no real time engine load factor data cases, it can only calculate under Rate of average load state
Vehicle oil consumption, (i.e. real-time the starting of finally obtaining of step S201 so when obtain the test of Fuel consumption correction parameter
Machine rotary speed data), vehicle as far as possible under daily travel route and daily vehicle load carry out, it is necessary to drive vehicle travel one section when
Between, general recommendations traveling more than 20km.
Step S202:Acquisition is when filling it up with oil again to the vehicle, the volume read-out data added.Specifically, in step
After S201 traveling a period of times, (judge that the standard that fuel tank is filled it up with is, automatic rifle of jumping as has added to gas station's top off again
Full Tanks), while obtain this and fill it up with volume read-out data to be added needed for oil.It should be noted that in order to ensure parameter
Going property of standard, when test, preferably refuel on the same fuel charger in same gas station, i.e. step S202 and step S201 fills it up with oily
The attribute of oil should be consistent.
Step S203:System is calculated using the engine speed data, default engine displacement and default initial oil consumption
Number, several the instantaneous fuel consumption values being calculated in running time, and acquire the accumulative fuel consumption values in the running time.It is default
Engine displacement obtains vehicle motor displacement data generally by data such as the specifications of the vehicle.Preset initial oil consumption meter
It is the empirical value drawn by many experiments to calculate coefficient, and in the present embodiment, it is 0.272 to preset initial oil consumption design factor.Tool
Body, the calculation formula of instantaneous fuel consumption values is as follows：

Show engine speed data (unit rpm), V represents default engine displacement (unit m^3).In the present embodiment, set
An engine speed data N is gathered in units of every 1sm, then once instantaneous fuel consumption values, therefore, M are calculated per 1stIt represents in 1s
Instantaneous fuel consumption values.
In addition, the calculation formula of accumulative fuel consumption values is as follows：
In formula (2), M represents accumulative fuel consumption values, and t represents engine start duration, unit s.
Step S204:The ratio of the volume read-out data and the accumulative fuel consumption values is calculated, to obtain correction factor, and profit

Specifically, revised oil consumption design factor calculation formula is as follows：
K=Mr/M (3)
In formula (3), K represents correction factor, and M represents accumulative fuel consumption values (above-mentioned steps S203 is calculated), MrIt represents
Volume read-out data (above-mentioned steps S202 is obtained, i.e. practical oil consumption value in this period of vehicle traveling, unit ml).
It should be noted that above-mentioned steps S201-S204 at least need to gas station fill it up with oil twice, for avoid it is accidental because
The interference of element repeats the process 3~4 times of step S201-S204 in the present embodiment, then the Fuel consumption correction got every time is joined
Numerical value is averaged.I.e.：Repeat the utilization revised oil consumption design factor, the default engine several times
Engine speed data during the traveling of discharge capacity and the vehicle whithin a period of time is calculated, and obtains the vehicle
The process before oil consumption within described a period of time, to obtain several revised oil consumption design factors, and described in calculating
The average value of several revised oil consumption design factors, using the average value as the revised oil consumption design factor.
It is tested in advance by above-mentioned steps S201-S204, obtains the revised oil consumption design factor of the vehicle.From
And during the actual traveling of the vehicle usually, different time can be calculated using the revised oil consumption design factor
Oil consumption in section (referring specifically to step S205).
Step S205:Utilize the revised oil consumption design factor, the default engine displacement and the vehicle
The engine speed data during traveling whithin a period of time is calculated, and obtains oil of the vehicle within this time
Consumption.Specifically, the calculation formula of oil consumption of the vehicle within this time is as follows：
Wherein, M' represents the oil consumption of the vehicle whithin a period of time, and r represents to preset initial oil consumption design factor, N'mTable
Show engine speed data, V represents default engine displacement, and K represents correction factor, and T represents engine start duration, and unit is
s。
