The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
It should be noted that during RDE test, although travel route not to be taken to target vehicle
Unification is carried out, but since RDE test has target vehicle travel route in the process of moving, driving cycle, stroke dynamics
Stringent regulation, and introduce " driving cycle ", " verification of stroke kinetic characteristics " and " normality of CO2 window and complete
Property verifying " etc. verification methods.When any one in above three verification method is unsatisfactory for requiring, then RDE test failure.But it is real
In the test-drive of border, due to by traffic condition (for example, congestion, normal, unimpeded), vehicle-state (for example, engine condition,
Mileage travelled, maintenance state), the influence of the changeable factor such as actual road conditions (such as pavement quality, width of roadway, gradient), can
Cause above-mentioned requirements below standard, so as to cause test result failure.Therefore, need to reasonable selection and planning to RDE test course,
To guarantee the success rate of RDE test.

Unit is gram every km (g/km)；CO is the CO emission measured, and unit is gram every km (g/km)；CO2To measure
CO2 emissions, unit be gram every km (g/km)；D is the density that fuel oil is tested under 288K (15 DEG C), unit thousand
Gram per liter (kg/L).
Two test vehicles are carried out with the unified Light-duty Vehicle test procedure (Worldwide-harmonized in the whole world respectively
Light vehicles Test Cycle, WLTC) circulation 6 I type emission testing of state, obtain the discharge about CO2, HC, CO
Pollutant measurement value, unit are gram every km (g/km), and test result is as shown in table 1, that is, calculates No. 1 vehicle CO2, CO, HC and account for
Oil consumption specific gravity is respectively 99.782%, 0.00742%, 0.211%；No. 2 vehicles CO2, CO, HC account for oil consumption specific gravity
99.239%, 0.732%, 0.031%.Fuel consumption depends on CO2, CO and HC in exhaust contaminant known to formula,
Wherein, CO2 accounting is all larger than 99.2%, therefore the influence of CO, HC to oil consumption can be ignored.Formula (1) can be simplified are as follows:
FC=0.1154/D × (0.273 × CO2) (2)
Formula (2) is converted, is obtained:
FC1=0.1154/D × (0.273 × CO2)/100×1000×Vi/3600 (3)
Wherein, Vi is vehicle automobile's instant velocity, and unit is kilometer per hour (km/h)；FC1 is transient fuel consumption, unit
It is (ml/s) per second for milliliter.Wherein, transient fuel consumption is instantaneous oil consumption.
The vehicle automobile's instant velocity Vi and carbon dioxide measurement CO obtained according to measurement2It can derive CO2Instantaneous discharge measuring
Value, can also be denoted as the instantaneous discharge amount of CO2, obtain:
CO2_ 1=CO2×Vi/3600 (4)
Wherein, CO2_ 1 is CO2Instantaneous discharge measuring value, unit are gram (g/s) per second.
Formula (4) are substituted into formula (3), the calculation formula of the instantaneous discharge amount of CO2 can be obtained, as follows:
Wherein, CO2_ 1 is the instantaneous discharge amount of CO2, and FC1 is instantaneous oil consumption, and D is that the close of fuel oil is tested under 288K (15 DEG C)
Degree.
In embodiment, the corresponding instantaneous discharge amount of CO2 directly can be calculated by the instantaneous oil consumption in duty parameter,
And the instantaneous discharge amount of the CO2 being calculated is divided into multiple windows, and based on CO2 characteristic curve to the normality of CO2 window and
Integrality is verified, thus the simply and easily verifying to completing to the normality and integrality of CO2 window.
On the basis of the above embodiments, the method for determination of drive route to be measured, comprising:
All drive routes on default map are screened based on default route alternative condition；Default route choosing will be met
The drive route of condition is selected as drive route to be measured.
Wherein, default route alternative condition refers in six standard of state about RDE test course selection principle.In embodiment
In, all drive routes on default map can be screened about RDE test course selection principle according in six standard of state,
To obtain meeting the route in six standard of state about RDE test course selection principle, and using the route as drive route to be measured.

In, target vehicle need to be placed on to progress six WLTC operating condition emission testing of state in default laboratory, measurement target vehicle is low in circulation
Fast section, high regime, the average speed of ultrahigh speed section and corresponding CO2 discharge amount, are denoted as Mco respectively2_ low speed、Mco2-_ high speed、
Mco2_ ultrahigh speed, unit g/km.Meanwhile with WTLC recycle in CO2 total release generally as a reference value partition window.Wherein,
It is divided according to the average speed of each window, being less than 45km/h is urban district window, and 45-80km/h is suburbs window, is greater than 80km/
H is high speed window.After obtaining low speed segment, high regime, the average speed of ultrahigh speed section and corresponding CO2 discharge amount, meter
CO2 Emission characteristic curve is calculated, in order to compare the instantaneous discharge amount of CO2 with CO2 Emission characteristic curve.
S320, it screens to obtain drive route to be measured according to default route alternative condition.
