Fig. 2 is the process flow diagram of the ECU (Electrical Control Unit) method of testing in the specific embodiment of the invention.As shown in Figure 2, the testing process of ECU (Electrical Control Unit) may further comprise the steps:
Step 201, model are downloaded and the process variable monitoring unit adopts Matlab/Simulink to set up engine, genset, battery, load and operating mode model.
The engine body model that wherein is used to control emulation is to satisfy certain real-time, and requirement should not be too complicated, adopts the mean value modeling method for this reason, set up the turbocharged and intercooled diesel engine model.The mean value modeling method thinks that all high frequency contents of engine all are transient change and reach stable state, from the basic physical characteristics of engine, by time yardstick principle, only considers the time average effect of engine condition variable and the synthesis result of each process.The composition of the turbocharged and intercooled diesel engine mean value model of building comprises pneumatic plant, charge air cooler, draft tube, engine dynamics, gas outlet, six subsystems of turbine.
About the generator modeling, consider the influence of generator alternating current side equivalent inductance, rectification phase place crossover can cause voltage drop, for 6 pulse all-waves not three-phase synchronous generator-the rectifier bridge of controlled bridge-type rectification steady-state circuit is arranged.
If do not consider the internal resistance pressure drop and the torque loss of three phase windings, then magneto alternator-rectifier bridge dc voltage, electromagnetic torque equation are as follows:
U dc = K e ω m - K x ω m I dc T e = P m ω m = P dc ω m = K e I dc - K x I dc 2
T in the formula eBe generator electromagnetic torque, N.m; K eω mBe the induction electromotive force of generator, V; K xω mBe equiva lent impedance, K x=3PL g/ π changes with generator speed; Wherein P is the power generator electrode logarithm, L gBe generator armature synchronous inductance H.
The generator input torque is passed over through a gearbox by engine, speed increasing ratio i E-g=30/19, according to torque balance following relation is arranged:
T eng i e - g - T e = 0.1047 ( J e i e - g 2 + J g ) dn g dt n g = i e - g n eng
Following formula T EngBe engine output torque, N.m; n Eng, n gBe respectively engine, generator speed, r/min; J e, J gBe respectively engine, generator moment of inertia, kgm 2
For the lead-acid battery modeling, the core of electric battery modeling is the modeling to electric battery terminal voltage and internal resistance characteristic, therefore can be simplified battery model.
R ChAnd R DchBeing respectively the internal resistance that discharges and recharges of battery, is the function of battery SOC and temperature.Adopt power and the initial SOC of battery as input in the modeling process, determine the open-circuit voltage and the internal resistance of battery according to experimental data by the SOC of table look-up method of interpolation and current battery, thereby determined the terminal voltage and the electric current of electric battery.
Consider that based on the SOC algorithm of normalized current the influence of time-dependent current can determine battery SOC more exactly, so take this kind algorithm to come modeling.Normalized current SOC algorithm is to utilize normalized current I Ref(be battery rated capacity C NThe time hour discharge current) predict the SOC of battery, battery is at discharge current i ≠ I RefShi Rongliang and C NBe unequal.Using weighting coefficient α (i) can obtain the discharge capacity Q ' of battery equivalence, is i ≠ I thereby obtain at electric current RefResidual capacity C r:
C r = C N - ∫ 0 T α ( i ) i ( t ) dt

SOC = C r C N × 100 %
The main difficult point of this algorithm is calculated weighting coefficient α (i) exactly, utilizes the characteristic of battery constant-current discharge to find the solution usually.When with electric current I 0The volume change that causes when discharging fully is
Figure A20081010472900084
The time, then with electric current I 0Be equivalent to electric current I during partial discharge RefElectric weight Q ' during partial discharge Q:
Q ′ = Q C I 0 · ( C N - C I 0 ) + Q = Q · C N C I 0
Then can get weighting coefficient:
α ( I 0 ) = C N C I 0 = 1 ξ C ( I 0 )
Can get the cell voltage equation in conjunction with battery SOC algorithm and model circuit diagram:
U dc = V 0 - I b R dch ( I b > 0 ) U dc = V 0 - I b R ch ( I b < 0 ) SOC = C r / C N &times; 100 % V 0 = f 1 ( SOC , T ) , R dch , ch = f 2 ( SOC , T ) .
Consider that from the angle of the purpose of emulation and simplified model resistance of load module replaces, according to the power demand of operating mode, current power demand can actual test figure or simulate given, loads to power assembly by the mode that changes resistance value.The resistance input of resistance needs to calculate according to voltage U dc, the bus current Idc of current power P and dc bus, promptly R = U dc 2 P .
Step 202, each parameter model of power assembly system is downloaded among the dSPACE, this moment, dSPACE was the digitizing power assembly system, i.e. the model running unit.
Step 203, in ControlDesk (software that model running unit dSPACE carries) monitoring power assembly system some process variable parameter, in order to the accuracy of verification model.
Step 204, moving model move the power assembly system parameter model among the unit dSPACE, export the sensor signal of operational factors such as engine, genset and battery by the hardware interface circuit simulation of model running unit dSPACE.
Step 205, these sensor signals are gathered by ECU (Electrical Control Unit), and according to the series of algorithms of formulating in the ECU (Electrical Control Unit), the output pwm control signal returns to model running unit dSPACE from ECU (Electrical Control Unit).
Step 206, model running unit dSPACE adjust the running status of digitizing power assembly system according to pwm control signal.
Step 207, sensor parameters detect and collecting unit adopts LabView to develop in order to showing the virtual instrument instrument interface of all operational factors, and can write down all operational parameter values in the whole service process.
Step 208, detect and collecting unit sends the instruction of revising operational factor numerical value to ECU (Electrical Control Unit) by sensor parameters.
Step 209, employing LabView have developed the on-line proving program with opening and extendability characteristics of using, the on-line proving unit is according to control strategy, revise control operational factor numerical value to reach desired control effect, so just realized the online virtual demarcation of ECU (Electrical Control Unit).
Like this by this closed-loop system, can on the logical organization of program and algorithm, carry out omnibearing test to ECU (Electrical Control Unit).
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
