Description
Technical field
The present invention relates to engine control, relate more specifically to a kind of fuel engine load servo device and dynamic optimizing control method thereof.
Background technology
Test shows; The operation point that certain mechanical horsepower of fuel engines output can exist several different rotating speeds and moment of torsion to cooperate; There is an oil consumption nadir in a plurality of operation points of certain mechanical horsepower that driving engine output is identical, is the optimum matching operation point of rotating speed-moment of torsion.Oil consumption nadir under the different output power is linked to each other and makes the curve that smoothing processing obtains is exactly the optimum efficiency run curve of this driving engine.Fuel engines is most effective on this curve, consumes the mechanical energy maximum of the fuel oil acquisition of equivalent.
This shows that when fuel engines is operated under certain rotating speed, if the moment of torsion that is applied on it is identical with the moment of torsion that optimum efficiency run curve under current rotating speed requires, driving engine promptly is operated on the best efficiency point of current rotating speed.Driving engine is under different rotating speed; The moment of torsion that keeps being applied on the axle is always identical with the moment of torsion that the optimum efficiency run curve requires; Be that the rotating speed-moment of torsion of driving engine and the requirement of optimum efficiency run curve match; The fuel oil of engine consumes equivalent can obtain maximum mechanical energy, reach most economical running state.
Various fuel enginess all dispose step change transmission and toric transmission mechanical transmission mechanisms such as (CVT) in the present vehicle, regulate the rotating speed and the moment of torsion of coupling, and the rotating speed of expectation fuel engines-moment of torsion coupling is approached the optimum efficiency run curve.
The step change transmission of widespread usage has 4-5 speed stage, can carry out easy speed setting, but converter speed ratio can't be regulated continuously.When load torque because situation such as windage, load-carrying, road conditions, environment, wearing and tearing when changing, under the different rotating speeds of different shelves, put on the engine shaft moment of torsion seldom can with the optimum efficiency run curve require consistent.
A kind of toric transmission mainly is made up of active wheels, driven wheels, metal tape and Hydraulic Pump; And pass through to change the continuous variation that driving wheel, the flower wheel conical surface and V-type driving band ingear swinging radius are realized converter speed ratio, thereby realize that engine speed-moment of torsion matees preferably.But also there is obvious limitation in toric transmission: at first be that physical construction is complicated thereby its manufacturing cost is high; Moreover the inertia of physical construction and hydraulic efficiency pressure system is big thereby governing speed is slow; When engine throttle or the dynamic change of external loading moment of torsion; Particularly road conditions frequent variations, throttle frequently change, busy shift the time; Toric transmission (CVT) can not be adjusted converter speed ratio rapidly and accurately, and the probability that fuel engines is operated in the optimum efficiency run curve is still very low; Toric transmission (CVT) driving efficiency is lower than general gear transmission in addition.These shortcomings all have influence on applying of CVT.
Fuel engines configuration moment of torsion servo-loading unit; Can be according to the optimum efficiency run curve that prestores in the actual speed of driving engine and the main control unit computing machine; The moment of torsion data that obtain mating by current rotating speed, the motor through actuating device applies corresponding torque to fuel engines, can so that fuel engines be operated on the optimum efficiency run curve that prestores; Improved the operating efficiency of fuel engines greatly, energy-conservation obvious.
But because also there is dispersiveness in the fuel engines characteristic of same model; Can not unify; In addition along with constantly aging, the variation of used fuel oil of fuel engines parts, the variation of air-blending ratio, the external factor such as variation of engine temperature, the actual optimum efficiency run curve of fuel engines tends to depart from that initial producer provides or tests the optimum efficiency run curve of gained.When that is to say by the optimum efficiency run curve of servo-loading unit original stored control fuel engines; According to the moment of torsion that current rotating speed uses the optimum efficiency run curve stored to calculate, be not moment of torsion with the obtained optimum efficiency of this rotating speed coupling.That is to say that servo-loading unit does not make on the real optimum efficiency run curve after fuel engines is operated in variation, thereby energy-saving effect will be given a discount.

On the basis of the above torque rating T that obtains, main control unit 9 is carried out the automatic optimal programs, increases torque rating beginning optimizing with the long dT of optimizing step pitch automatically, and gives optimizing and just be designated.Main control unit 9 is sent into servo-driver 8 with the setting of T+dT; The current phasor of relative position signal loading second rotor 5 windings of the torque setting that servo-driver 8 is sent here according to main control unit and second rotor 5, the first rotor 4, control fuel engines 1 is with torque T+dT trail run.
Main control unit obtains under speed N, torque T+dT state at optimizing measuring and calculating time dt (h from the flow sensor on the oil circuit; Hour) interior consumption of fuel; And calculate the mechanical energy W=N that fuel engines exports in the time at dt * (T+dT) * dt/9550 (kWh, kilowatt-hour) according to present speed N, torque T+dT, obtain fuel engines unit's mechanical energy consumption fuel oil value between this trial run period thus; Be the consumption of fuel M/W (g/kWh, gram/kilowatt-hour) of every kilowatt-hour of mechanical work.
Relatively rotating speed is under the situation of N, and the fuel engines 1 unit mechanical energy consumption fuel oil data of optimizing shaft down moment of torsion (T+dT) and the rotating speed of main control unit 9 Computer Storage are the oily data of consumption of corresponding point on the optimum efficiency run curve under the situation of N.If the unit mechanical energy consumption of fuel of trail run point is less than the consumption oil index on the optimum efficiency run curve in optimizing measuring and calculating time dt; It is the optimizing success; Then replace original T and deposit main control unit 9 computing machines in T+dT; Optimizing is designated just constant, and the computer continued of main control unit 9 is as stated above with T+dT (noticing that this moment, T upgraded) optimizing once more.Otherwise if moment of torsion is in the trail run of T+dT, unit mechanical energy consumption of fuel is greater than the data on the optimum efficiency run curve, i.e. optimizing failure, then change optimizing be designated negative, and reverse optimizing.The computing machine of main control unit 9 is sent into servo-driver 8 with torque T-dT, control fuel engines 1 output shaft trail run under this moment of torsion, and compare its consumption of fuel.If the unit mechanical energy consumption of fuel of T-dT trail run point is less than the consumption oil index on the optimum efficiency run curve in optimizing measuring and calculating time dt; It is the optimizing success; Then replace original T and deposit main control unit 9 computing machines in T-dT; Optimizing is designated negative constant, and the computer continued of main control unit 9 is as stated above with T-dT (noticing that this moment, T upgraded) optimizing once more.Otherwise, if moment of torsion be trail run unit's mechanical energy consumption of fuel of T-dT greater than the data on the optimum efficiency run curve, then change optimizing and just be designated, and forward optimizing once more.

Computing machine can be intervened the automatic optimal program as required, stops or restarting.After the automatic optimal program stopped, main control unit 9 was according to present speed signal N, confirmed the best torque T that matches according to the optimum efficiency curve of storage, and the setting of this torque rating T is sent into servo-driver 8, the operation of control driving engine.Restart the automatic optimal program then still by the process flow operation of above-mentioned steps.
Two principles are followed in choosing of the long dT of optimizing step pitch: the one, and optimizing is enough quick, and this requires dT bigger; The 2nd, optimizing point is enough close, in order to avoid dT crosses optimization point, this requires dT enough little.DT preferably can be in the scope of 0.1～daNm, but is not limited thereto.Arithmetic speed speed according to main control unit 9 computing machines is different with the speed of driving engine optimal economic run curve rate of change, confirms the size of dT.The arithmetic speed of main control unit 9 computing machines is very fast, and then dT is less; Driving engine optimal economic run curve rate of change is very fast, and then dT is bigger.DT is less than 5% of nominal torque, in order to avoid cause the control vibration.
Optimizing measuring and calculating time dt but is not limited thereto preferably in 0.1～5 second scope, and is concrete relevant with the fuel consumption measurement speed and the precision of flow sensor 11.For example fuel consumption measurement rapid speed, precision are higher, and then dt is less.
In one embodiment, 1.8L discharge capacity engine petrol is installed this servo-loading unit, and adopts the operation of this dynamic operation control method.A point as shown in Figure 2; In engine operation under the operating mode of horsepower output 15kW and situation about remaining unchanged; If engine operation is 3500 revolutions per minute in the non-economy operation point, 40.9 newton meteies, then the oil consumption of its unit output mechanical energy be 335 the gram/kilowatt-hour.But engine working point is adjusted to the B point on the optimal economic run curve through this add load control and this progress control method; I.e. 1302 revolutions per minute; 110 newton meteies, then the oil consumption of its unit output mechanical energy be reduced to 250 grams/kilowatt-hour, reduce oil consumption 25.4%.When change or engine wear because of fuel oil quality, when this optimum efficiency run curve reality when 10% skew takes place in this point, if still press the torque control of virgin curve, oil consumption is higher by 1%～20% than minimum.These apparatus and method dynamically update the optimum efficiency curve, and oil consumption is minimum when making the output of same mechanical energy.Look operation point difference, drift condition difference, then fuel-economizing situation is also different, but all can keep the maximum energy-saving state.
