Accompanying drawing 6 has been showed in the system of accompanying drawing 1 the curve chart of controlled voltage as the function of the time t that provides with abscissa with the form of example qualitatively.
The embodiment explanation
In accompanying drawing 1, total usefulness 1 indicates the voltage in the motor vehicles to produce and feed system.
This system comprises an alternating current generator (total usefulness 2 indication), comprising a magnetic field winding 3 and leggy armature or stator winding 4.In the embodiment of accompanying drawing 1, the latter is one three phase winding and comprises three with the interconnective winding of star-like arrangement mode.
The armature winding 4 of motor 2 is connected to the rectifier circuit 5 of a known type, and some diodes 6 that wherein comprise connect into three phase bridge.
Rectifier 5 has two output 5a and 5b, and they are connected to the two poles of the earth 8a and 8b by lead 7, and this is respectively the negative pole and the positive pole of storage battery 8 (for example lead-acid battery).
Usually, connect some on the battery 8 and may be selected to be the electric load that connects or disconnect.In accompanying drawing 1, these load represent with single variable load 9, and it can be connected into or disconnect by switch 10.
The voltage adjuster of generally representing with VR in accompanying drawing 1 produces with voltage and feed system interrelates.
Voltage adjuster VR comprises the circuit 11 of the numerical value of a controlled voltage that is used for obtaining generation system 1 basically.And as an example, this controlled voltage can be the output voltage of rectifier 5 or the voltage in the battery 8.
Control unit ECU is connected to drive circuit 12, and the latter's output is connected to a port of magnetic field winding 3.In the embodiment of showing as an example in accompanying drawing 1, another port of magnetic field winding 3 has been connected to the output port 5a of rectification circuit 5.
Extremely simply and in a well-known manner, the numerical value of the controlled voltage that control unit ECU gathers according to circuit 11 relies on drive circuit 12 to control the current's intensity that flows in the magnetic field winding 3 of alternating current generator 2 at work.
Voltage adjuster VR also can comprise the circuit 13 that is used to drive indicator light L, and its input is connected to the output of unit ECU.In the embodiment of in accompanying drawing 1, showing as an example, lamp L is placed between the positive pole of the output of circuit 13 and battery, and be in series, and can operate by key K with (for example with the igniting of motor vehicles and starter switch combine) switch 14.
For the following more clear reason of illustrating soon, voltage controller VR can advantageously comprise another input circuit 15, it is connected to one of alternator armature winding 4 and goes up mutually, so that the signal Phi of an indication alternator rotor rotating speed is provided for another input of control unit ECU.Being used for of adjuster VR obtained the input circuit 11 of the controlled voltage instantaneous value of generation system, and it can be with reference to the accompanying drawings 2 and accompanying drawing 3, and (for example) constitutes in described mode hereinafter.
Offer the level of the logic control signal SEL of circuit 16 according to control unit ECU, the signal VO of output that selects circuit 16 is corresponding to the output voltage of rectifier circuit 5 or the voltage in the battery 8.
The output of selection circuit 16 is connected to the input of analog/digital converter 17 by a noise inhibiting wave filter 18.And the output of transducer 17 is connected to control unit ECU.
Control unit ECU controls transducer, so that from represent the continuous digital signal X (n) of the true instantaneous value of controlled voltage here with predetermined frequency collection.
As mentioned before, above-mentioned input circuit 11 can be used to monitor the output voltage of rectifier 5, perhaps the voltage in the monitoring battery 8.In a kind of situation in back, the input 16a of selection circuit 16 must be connected to the anodal 8a of battery 8; And a kind of in front situation, the input 16a of this circuit must be connected to the output 5a of rectifier circuit 5.
It is to be in this or to be in the sort of connection status that electric unit ECU can be advantageously provided into automatic identification input circuit 11, and this flow chart as hereinafter with reference accompanying drawing 3 is described.
For the input that is using of identification selection circuit 16 is input 16a or input 16b, control unit ECU can be set carries out one section program according to the flow chart of accompanying drawing 3.In beginning (in accompanying drawing 3, representing) afterwards with 50, in following step 51, this section program of preparing for unit ECU sends a signal SEL (for example SEL=" 1 ") to circuit 16, and its state or level are corresponding to the signal of gathering at input 16a at that time (if any).Next unit ECU gathers digital signal corresponding X (step 52 in accompanying drawing 3) and checking (step 53) this signal whether within predetermined scope.If really so, this just means that the input of selecting circuit 16 using is input 16a, therefore connects (step 54 in accompanying drawing 3) in existence between input 16a and the battery.If signal is not within predetermined scope, control unit ECU changes state or the level (step 56) of signal SEL, so that can be sent to the output of circuit 16 at the signal of input 16b collection.
As example, input circuit 15 can comprise a square wave and form circuit, its converts the phase signal that obtains from armature winding to square-wave signal, and the rotating speed of its frequency and generator amature is proportional, so also proportional with the rotating speed of the internal combustion engine of motor vehicles.
No matter be which voltage in the generation system 1 is controlled, the function mode of voltage adjuster VR all is described following 5 flow chart with reference to the accompanying drawings.
This control program is defined in " beginning " step (square frame 100 in the accompanying drawing 5) afterwards, in the moment of being discussed, by unit ECU acquisition phase signal Phi and controlled voltage digital numerical value X (n) (square frame 101).
Next control unit ECU prepares the instantaneous value E (n) (square frame 102) of error of calculation amount E, and this is representing the predeterminated target numerical value X of controlled voltage
REFAnd the difference between the actual instantaneous value X (n);
E(n)=X
REF-X(n)
Control unit also prepares to calculate the instantaneous value Y (n) corresponding to form the controlled quentity controlled variable Y of the current's intensity that flows in the magnetic field of alternating current generator winding 3, and this depends on the preceding value of this controlled quentity controlled variable and instantaneous value and the preceding value of margin of error E.Y (n) can calculate according to following formula easily:
Y(n)=a
1Y(n-1)+a
2Y(n-2)+b
0E(n)+b
1E(n-1) (1)
In the superincumbent formula, a
1, a
2, b
0And b
1It is the predetermined control coefrficient of alternating current generator that adopts according in the system 1.In addition, Y (n-1) and Y (n-2) represent the numerical value of controlled quentity controlled variable Y two previous (storing).E (n) is the numerical value of problem discussion moment margin of error E in one's power, and E (n-1) is this margin of error next-door neighbour's of calculating a preceding value.
The mode that is used to pre-determine control coefrficient a1 and b1 can be so that control formula (1) can allow alternating current generator show the performance of expectation, in other words, when the rotating speed of electrical load and engine changes, can allow its output voltage or the voltage in the battery keep constant and stable basically.
The predetermined value of these coefficients and the desired value X of voltage
REFBe stored in the memory device that is included among the control unit ECU.
In the first embodiment, control unit ECU is designed to the instantaneous value E (n) and relevant predetermined threshold E of the margin of error that will calculate
ThCompare (square frame 103 in the accompanying drawing 5).
At first kind also is in the flexible embodiment, and control unit ECU is designed to the increment of checking that controlled quentity controlled variable Y is nearest, and just whether difference Y (n)-Y (n-1) has surpassed predetermined thresholding Y
Th, this also signal in the square frame 103 of accompanying drawing 5.
No matter in which kind of situation, if E (n) is lower than relevant thresholding E
ThIf perhaps Y (n)-Y (n-1) is lower than corresponding thresholding Y
ThSo as described in the square frame 105 of accompanying drawing 5, control unit ECU sends the signal corresponding to the numerical value Y (n) that calculates in the moment of being discussed to drive circuit 12, next the successor value of acquisition phase signal Phi and controlled voltage X (square frame 106,101 and follow-up square frame in the accompanying drawing 5) again.
As long as under E (n) or Y (n)-Y (n-1) maintenance thresholding separately, then adjuster VR continues according to above-mentioned circulation running.The signal that drive circuit 12 is received from control unit ECU is corresponding to the numerical value of the Y that calculates in the moment of being discussed (n), also corresponding to certain duty ratio numerical value of the signal that offers analog line driver 20 (accompanying drawing 4), and this is controlling current's intensity in the winding 3 of the magnetic field of alternating current generator 2.
Shown in square frame among Fig. 5 107, can in above-mentioned running circulation, advantageously introduce a kind of inspection in cycle (T) to signal Phi; If this cycle is less than a predetermined threshold T
Th, then can " skip " E (n) or Y (n)-Y (n-1) are compared this step with separately thresholding, and no matter under which kind of situation, control unit ECU offers drive circuit 12 with the signal of the numerical value of a correspondence and Y (n).
To thresholding T
ThSelect so that make it (for example corresponding to the certain rotating speed of the internal combustion engine of motor vehicles, the rotating speed of alternator rotor is 2800 rev/mins), if on this numerical value, the unexpected increase to Current draw of the electric load generation that then connects in the system 1 in no case produces serious influence to the rotating speed of engine easily.
Yet, when the internal combustion engine of motor vehicles to be lower than corresponding to the phase signal period T
ThThe rotation speed operation of thresholding the time, that is to say, basically when rotating speed is low when may badly influence the rotating speed of internal combustion engine to the unexpected increase of Current draw in the system 1, for the controlled function that the further part of the square frame 107 of accompanying drawing 5 provides will be implemented.What in fact relate to according to the distinguished characteristics of voltage adjuster VR of the present invention is running under these conditions.
Thus, imagination internal combustion engine (rotor of alternating current generator 2 is too thus) rotates with relatively slow speed, in any case, be to be lower than corresponding to period T to be set at threshold T as phase signal Φ
ThThe time numerical value.If under these conditions, carve at a time, the numerical value E (n) that calculates becomes greater than corresponding threshold value E
Th, perhaps difference Y (n)-Y (n-1) becomes greater than corresponding thresholding Y
Th, control unit ECU then adopt different strategies to control electric current (square frame 108 and follow-up square frame in the accompanying drawing 5) in the magnetic field winding 3 of alternating current generator then.
Before the method for describing this controlling filed electric current, can point out condition E (n)>E from the angle of physics
ThMean the relative desired value X of controlled voltage
REFReduction surpassed predetermined quantity.
On the other hand, condition Y (n)-Y (n-1)>Y
ThMean: for controlled voltage is remained essentially in desired value, the field current that needs to increase has surpassed predetermined quantity.
Therefore said two conditions are all indicating the electric load 9 that is connected to voltage generation and feed system 1 to require very large electric current of transmission above, corresponding to this, the impedance moment of torsion that 2 pairs of internal combustion engines of alternating current generator apply will have potential a dangerous increment.
Shown in the square frame 108 of accompanying drawing 5, when the some generations in the above-mentioned condition, control unit ECU will offer 12 1 signals of drive circuit, the numerical value of the Y (n) that corresponding with it is remarkablely calculates recently, but increased a predetermined increment constant Δ Y on this numerical value.
Accompanying drawing 6 has been showed controlled voltage V in the system 1 qualitatively

Drive the electric current in the magnetic field winding 3 in the alternating current generator in the continuous evenly mode of increment, rather than on the basis of the numerical value of the Y that calculates on the basis of above-mentioned formula (1) (n), drive this electric current.
