Description
Technical field
Heavy ride examination Fuel Consumption or the detection method of discharge, are that heavy goods vehicles appear on the stage die trial plan completely in chassis dynamometer
A kind of detection method of vehicle cruising mode or transient condition the examination of road, detection Fuel Consumption or waste gas discharge is carried, belongs to automobile
Performance Platform test technical field.
Background technology
Existing fully loaded heavy goods vehicles cruising mode or transient condition detection Fuel Consumption or waste gas discharge, cruising mode are usual
It is the examination of road, transient condition is typically by GB GB/T27840-2011《Heavy type commercial vehicle Fuel Consumption measuring method》, car
Intend transient condition the examination of road C-WTVC circulation to detect Fuel Consumption or waste gas discharge in chassis dynamometer die trial of appearing on the stage, exist
Following some deficiencies：1st, the average correction time slided on stand using vehicle adjusts the operation of chassis dynamometer loading capacity
Property is bad；2nd, when chassis dynamometer equivalent inertia is not equal to the equivalent translation inertia of vehicle, platform examination does not have specification simulation loading
Power；3rd, the necessary condition imperfection of gearbox gear is determined；4th, without evaluation vehicle comprehensive dynamic.Try to fire using heavy ride
Material consumption or the detection method of discharge can overcome these not enough.Transient condition is comprising vehicle idling, acceleration, constant speed, subtracts
Speed, cruising mode is the special case that transient state accelerating mode acceleration is 0.
The content of the invention
Fully loaded heavy type ride examination has following characteristics：Loading load is larger will to prevent empty-car driving wheel load less than normal in roller
On trackslip；Heavy goods vehicles gearbox gear quantity and ratio disparities are larger is difficult to unify gear, same vehicle cruising mode or adds
The Fuel Consumption of fast operating mode difference gear differs greatly, and to ensure accurate and operation the uniformity of detection, needs clear and definite high gear
Principle：Must be used compared with high gear under the conditions of engine output torque and rotary speed property is met, and determined necessary compared with high gear
Calculate engine torque load and rotating speed.
1st, vehicle the examination of road obtains the coefficient of rolling resistance formula and coefficient of air resistance formula under standard ambient condition, or
When vehicle is the examination of road corresponding coefficient formula that modification vehicle then can refer to basic vehicle, or by Chinese invention patent application《Vapour
The simulation of car multi-state the examination of road Fuel Consumption calculates detection method》, application number：201410444250.4, with belonging to inspection vehicle
Class of vehicle statistics corresponding coefficient formula, calculate each speed the examination of road running resistance of institute inspection vehicle.
2nd, cruising mode's Platform test need not judge the comprehensive dynamic of vehicle, and transient condition Platform test need to first judge car
Comprehensive dynamic, to engine torque external characteristic curve or engine output net torque external characteristic curve digitization after,
In the range of engine stabilizer rotating speed, calculate engine resistance torque by each gear for circulating each speed point and be not more than δ × Me to sentence
It is disconnected, in formula：δ is engine torque coefficient, typically slightly larger than or equal to 1；Me is the engine output of correspondence gear speed point
Moment of torsion.First calculate the engine torque load of each speed point, if in certain accelerating mode overall process by instantaneous acceleration or
Average acceleration calculates engine torque load, and each gear has multiple points to exceed regulation torsion in the engine stabilizer range of speeds
Square limit value δ × Me, can determine that the comprehensive dynamic of vehicle is unqualified, i.e., cannot theoretically realize the actual row of the accelerating mode
Sail, it is impossible to which completing transient-cycle in point state does not carry out platform examination, only by the comprehensive dynamic of calculating method it is qualified after just carry out platform and try loading
Detection.
3rd, the platform examination resistance formula and the power of each speed of vehicle neutral position sliding measuring vehicle roller whole system on stand
Sensor vibration power, the device for power absorption that the examination of road resistance of same speed subtracts platform examination resistance as speed cruising mode adds
Power is carried, if force snesor vibration force is larger with respect to total load ratio, the loading force of device for power absorption can be with superposition vibration force.
4th, accelerating mode platform examination loading force wants the equivalent translation of superposition vehicle to be used on the basis of cruising mode's platform examination loading force
The difference of amount (vehicle total quality and non-driven wheel equivalent inertia sum) and stand equivalent inertia is multiplied by the inertia of regulation acceleration
Acceleration resistance, idling and decelerating mode device for power absorption are not loaded with.
5th, platform examination accelerating mode process, be according to correlations such as engine, gearbox, primary actuator, the vehicle bodies for logging in vehicle
Technical parameter, calculates engine torque load and rotating speed to determine compared with high gear, while to consider the minimum length in time of gear,
Excessively shift hunting is avoided, as the minimum length in time for rising three gears are not less than 3s, when the upshift more than or equal to four gears is most short lasting
Between be not less than 6s, and engine speed is greater than its minimum stable engine speed ability upshift.
6th, the correction of detection Fuel Consumption is conducive to accurately comparing and evaluating under standard ambient condition, calculates correction
Fuel Consumption QSchool=QInspection/ a, Q inspection are detection Fuel Consumption, and a is engine power correction coefficient.
Heavy ride examination Fuel Consumption or the detection method of discharge are heavy goods vehicles appears on the stage examination simulation road in chassis dynamometer
Examination cruising mode or transient condition detection Fuel Consumption or a kind of method of discharge, it is characterised in that：The examination of transient condition platform will
After engine output torque curve data, judged just to carry out Platform test after vehicle comprehensive dynamic is qualified with calculating method；
Vehicle rolling resistance formula and air drag formula are first determined to calculate each speed the examination of road resistance, and then vehicle is in stand overhead
Gear slides the resistance formula of measuring vehicle roller whole system and the force snesor vibration force of each speed, the examination of road resistance of same speed
Power subtracts the device for power absorption loading force of vehicle roller whole system resistance as cruising mode, and accelerating mode platform examination power is inhaled
Receiving apparatus loading force on the basis of cruising mode's loading force, also want the equivalent translation inertia of superposition vehicle and stand equivalent inertia it
Difference is multiplied by the inertia acceleration resistance of regulation acceleration, and sensor vibration power can be reinforced with superposition or without end；The examination of accelerating mode platform is pressed
The vehicle associated technical parameters of login, calculate engine torque load and rotating speed, are meeting engine output torque and rotating speed spy
Property under, selection continues relatively high gear measurement Fuel Consumption or the waste gas discharge of stipulated time, and engine speed is big during upshift
In equal to its minimum stable engine speed, prompting in good time is put into gear and is operated, and can calculate correction fuel consumption QSchool=QInspection/ a, QInspectionIt is inspection
Fuel Consumption is surveyed, a is engine power correction coefficient.
