(1-2) action of power generation control 2
Then, the action to the power generation control 2 of present embodiment describes.Fig. 3 and Fig. 4 are the oscillograms of the example of expression basic clock signal CK, triggering signal TR, output voltage and output current.
Expression imposes on the output current of 1 phase of the output voltage of 1 phase of the basic clock signal CK of CPU52, the triggering signal TR that imposes on 1 thyristor 7b, three-phase mixed electrical bridge circuit 7 and three-phase mixed electrical bridge circuit 7 among Fig. 3 and Fig. 4.The control cycle that the period T of basic clock signal CK is equivalent to microcomputer 5 for example is 40 μ sec.Triggering signal TR and basic clock signal CK rise synchronously.Therefore, the timing of triggering signal TR is controlled control cycle T as unit.
In the example of Fig. 3, CPU52 detects rise of output voltage at moment t1, and is synchronous in the rising of moment t2 and basic clock signal CK, the pulse of rising triggering signal TR.The pulse rising of response triggering signal TR and thyristor 7b connects.Thus, from moment t2 to moment t3 at diode 7a and thyristor 7b circulating current.In the example of Fig. 3, the value of output current is 7.5A.
In the example of Fig. 4, CPU52 detects rise of output voltage at moment t1, and is synchronous in the rising of moment t3 and basic clock signal CK, the pulse of rising triggering signal TR.The pulse rising of response triggering signal TR and thyristor 7b connects.Thus, from moment t2 to moment t3 at diode 7a and thyristor 7b circulating current.In the example of Fig. 4, the value of output current is 8.5A.
Fig. 5 is the figure that is illustrated in an example of the output current in the power generation control 2.In Fig. 5, under the situation of the pulse of the timing rising triggering signal TR of the example of Fig. 3, the value of output current is 7.5A, and under the situation of the pulse of the timing rising triggering signal TR of the example of Fig. 4, the value of output current is 8.5A.
The timing of triggering signal TR is in order to control control cycle T as unit, output current has centrifugal pump.In above-mentioned situation, the value of output current can not be controlled at 8.0A by the timing (phase angle) of controlling triggering signal TR.In the power generation control 2 of present embodiment, can output current be controlled at arbitrary value by following method.
CPU52 sets current control cycle Tc.At this, (for example 50msec) sets current control cycle Tc fully greatly than the swing circle under the idling conditions of engine 30.Current control cycle Tc is made up of the first control period ta and the second control period tb as shown in the formula (1).
Tc＝ta+tb … (1)
In addition, the first control period ta is called duty ratio Rd with respect to the ratio of current control cycle Tc.
Rd＝ta/Tc＝ta/(ta+tb) … (2)
At this, the first control period ta and the second control period tb are set at the integral multiple of the control cycle T of microcomputer 5.Also can make current control cycle Tc certain, by adjusting the first control period ta and second control period tb change duty ratio Rd.In addition, also can make the first control period ta certain, by adjusting the second control period tb and current control cycle Tc change duty ratio Rd.
At this, CPU52 is at the output current of the first control period ta according to the first instruction output current value I1 control three-phase mixed electrical bridge circuit 7, at the output current of the second control period tb according to the second instruction output current value I2 control three-phase mixed electrical bridge circuit 7.Promptly, CPU52 carries out the phase angle control of thyristor 7b at the first control period ta according to the output current and the equal mode of the first instruction output current value I1 of three-phase mixed electrical bridge circuit 7, carries out the phase angle control of thyristor 7b at the second control period tb according to the output current and the equal mode of the second instruction output current value I2 of three-phase mixed electrical bridge circuit 7.
Under this situation, CPU52 sets the first instruction output current value I1, second instruction output current value I2 and the duty ratio Rd according to the mode that the average output current value and the target output current value Itar of the three-phase mixed electrical bridge circuit 7 when the current control cycle Tc equates.Duty ratio Rd sets in the mode that satisfies following formula (3).
Itar＝I1·Rd+I2·(1-Rd) …(3)
Like this, CPU52 can be controlled at the average output current value of three-phase mixed electrical bridge circuit 7 target output current value Itar arbitrarily by the control first instruction output current value I1, second instruction output current value I2 and the duty ratio Rd.
Fig. 6 is the figure of an example that is illustrated in the control of the output current in the power generation control 2.In the example of Fig. 6, Itar is set at 8.0A with the target output current value.Under this situation, the first instruction output current value I1 is set at 7.5A, the second instruction output current value I2 is set at 8.5A.In addition, duty ratio Rd is set at 0.5.That is, the first control period ta and the second control period tb become equal.Under this situation, average output current value Iave is 8.0A.
Fig. 7 is the flow chart of output current control and treatment of the power generation control 2 that carries out of CPU52 of expression microcomputer 5.
Preestablish the initial value of target output current value Itar, the first instruction output current value I1, the second instruction output current value I2 and duty ratio Rd.
At first, CPU52 judges whether target output current value Itar changes (step S1).Target output current value Itar for example changes according to two-wheeled 100 state.Under this situation, a plurality of target output current value Itar and two-wheeled 100 state are stored in the memory 54 accordingly in advance.Two-wheeled 100 state is meant for example idling conditions, acceleration mode, Minus speed state and the constant speed state of engine 30.Two-wheeled 100 state is not limited to these states.Perhaps, target output current value Itar also can change according to the charged state and the discharge condition of storage battery 3.
Do not have at target output current value Itar under the situation of change, CPU52 carries out the phase angle control (step S2) of the thyristor 7b of triggering signal TR by the first instruction output current value I1 at the first control period ta.
Then, CPU52 carries out the phase angle control (step S3) of the thyristor 7b of triggering signal TR by the second instruction output current value I2 at the second control period tb.Afterwards, CPU52 returns the processing of step S1.
By the processing of execution in step S1～S3 repeatedly, average output current value Iave is controlled at target output current value Itar.
Under the situation of step S1 target output current value Itar change, the first instruction output current value I1 of the approaching target output current value Itar after changing of CPU52 decision and the second instruction output current value I2 (step S4).Under this situation, instruct output current value I2 to be set in the value up and down of target output current value Itar the first instruction output current value I1 and second.
Then, CPU52 is by following formula (3) decision duty ratio Rd (step S3).Thus, calculate the first control period ta and the second control period tb by following formula (2).Afterwards, CPU52 returns the processing of step S1, uses after changing the first instruction output current value I1, the second instruction output current value I2, duty ratio Rd, the first control period ta and the second control period tb processing of execution in step S1～S3 repeatedly.Thus, average output current value Iave is controlled at after changing target output current value Itar.
(1-3) effect of power generation control 2
According to the power generation control 2 of first execution mode, the arbitrary value between the first instruction output current value I1 that the restriction of the control cycle T that target output current value Itar can be set at microcomputer 5 is made decision and the second instruction output current value I2.Thus, the average output current value Iave of three-phase mixed electrical bridge circuit 7 can be controlled at arbitrary value.Therefore, can be to the output current of electric loading and storage battery 3 supply arbitrary values.In addition, by at random changing target output current value Itar, can at random change the value of the output current of supplying with to electric loading and storage battery 3 according to two-wheeled 100 the state or the state of storage battery 3 etc.
(2) second execution modes
(2-1) power generation control and two-wheeled formation
Fig. 8 is the block diagram of formation of the two-wheeled electrical system of the expression power generation control that possesses second embodiment of the invention.
The formation difference of the formation of the power generation control 2 of Fig. 8 and the power generation control 2 of Fig. 1 is further to be provided with the current sensor 8 of the output current value that detects three-phase mixed electrical bridge circuit 7.In the present embodiment, current sensor 8 is connected with positive side power line L2.The output signal of current sensor 8 imposes on microcomputer 5.The A/D converter 53 of microcomputer 5 converts the output signal of current sensor 8 to the current value of numeral.
(2-2) action of power generation control 2
Sometimes between from the output current value of the reality of three-phase mixed electrical bridge circuit 7 and the first instruction output current value I1 or the second instruction output current value I2, produce error because of the deviation of the characteristic of magneto-electric generator 1 or variations in temperature etc.In the power generation control 2 of present embodiment,, also can make the average output current value of three-phase mixed electrical bridge circuit 7 consistent by method shown below with target output current value Itar even produce such error.
Below, the action of the power generation control 2 of present embodiment is described.Fig. 9 is the figure that is illustrated in an example of the output current in the power generation control 2.
In Fig. 9, target output current value Itar is 8.0A.Under this situation, the first instruction output current value I1 is set at 7.5A, the second instruction output current value I2 is set at 8.5A, duty ratio Rd is set at 0.5.
In the example of Fig. 9, carry out under the situation of phase angle control according to the first instruction output current value I1, because the deviation of the characteristic of magneto-electric generator 1 or variations in temperature etc. make the output current value Ir1 and first of three-phase mixed electrical bridge circuit 7 instruct output current value I1 inconsistent, are 7.0A.In addition, carry out under the situation of phase angle control according to the second instruction output current value I2, the output current value Ir2 of three-phase mixed electrical bridge circuit 7 is consistent with the second instruction output current value I2.
Under this situation, to moment T11, become lower than target output current value Itar from the average output current value Iave of the reality of three-phase mixed electrical bridge circuit 7 from moment T10.
So, constantly below the T11, according to the output current value change duty ratio Rd that detects by current sensor 8.In the example of Fig. 9, duty ratio Rd is changed to than 0.5 little value.That is, the second control period tb is longer than the first control period ta.Its result, actual average output current value Iave is consistent with target output current value Itar.
Figure 10 is the flow chart of output current control and treatment of the power generation control 2 that carries out of CPU52 of expression microcomputer 5.
Preestablish the initial value of target output current value Itar, the first instruction output current value I1, the second instruction output current value I2 and duty ratio Rd.
To be made as I1sum at the present aggregate-value of the output current value among the first control period ta, the present aggregate-value of the output current value in the second control period tb is made as I2sum.In addition, the preceding aggregate-value till once of the output current value to the first control period ta is made as I1 ' sum, and the preceding aggregate-value till once of the output current value to the second control period tb is made as I2 ' sum.The initial value of aggregate-value I1 ' sum, I2 ' sum is 0.
At first, CPU52 judges whether target output current value Itar changes (step S11).Target output current value Itar is identical with first execution mode, according to for example two-wheeled 100 the state or the Status Change of storage battery 3.
Do not have at target output current value Itar under the situation of change, CPU52 judges that present instruction current value is that the first instruction output current value I1 still is the second instruction output current value I2 (step S12).
At step S12, present instruction output current value is under the situation of the first instruction output current value I1, and CPU52 carries out the phase angle control (step S13) of the thyristor 7b of triggering signal TR by the first instruction output current value I1.
In addition, CPU52 reads in by current sensor 8 detected output current value I1r (step S14).Then, CPU52 to the first control period ta preceding once till with output current value I1r and aggregate-value I1 ' sum addition, the present aggregate-value I1sum (step S15) that addition result is made as at the first control period ta.
At the present instruction output current value of step S12 is under the situation of the second instruction output current value I2, and CPU52 carries out the phase angle control (step S16) of the thyristor 7b of triggering signal TR by the second instruction output current value I2.
In addition, CPU52 reads in by current sensor 8 detected output current value I2r (step S17).Then, CPU52 to the second control period tb preceding once till with output current value I2r and aggregate-value I2 ' sum addition, addition result is made as present aggregate-value I2sum (step S18) in the second control period tb.
Then, CPU52 judges whether passed through current control cycle Tc (step S19).That is, CPU52 judges whether the first control period ta and the second control period tb finish.In the situation of not passing through current control cycle Tc, CPU52 returns the processing of step S11.
Under the situation of not passing through current control cycle Tc, CPU52 calculates the interior average output current value Iave (step S20) of current control cycle Tc by following formula (4).
Iave＝(I1sum+I2sum)/(ta+tb) …(4)
CPU52 judges whether average output current value Iave equates (step S21) with target output current value Itar.
Under average output current value Iave and the situation that target output current value Itar equates, CPU52 returns the processing of step S11.
Under the situation that average output current value Iave and target output current value Itar do not wait, CPU52 calculates the first average output current value I1ave and the 2nd average output current value I2ave (step S22) in the second control period tb in the first control period ta by following formula (5), (6).
I1ave＝I1sum/TA …(5)
I2ave＝I2sum/TB …(6)
In following formula (5), (6), TA is the number of times that reads in of the output current value I1r in the first control period ta, and TB is the number of times that reads in of the output current value I2r in the second control period tb.
And then CPU52 calculates duty ratio Rd (step S23) according to the first average output current value I1ave and the 2nd average output current value I2ave by following formula (7) in the mode that average output current value Iave and target output current value Itar equate.
Rd(I1ave-Itar)+(1-Rd)(I2ave-Itar)＝0 …(7)
Thus, upgrade duty ratio Rd.Follow the renewal of duty ratio Rd that the first control period ta and the second control period tb are upgraded.Afterwards, CPU52 returns the processing of step S11.By the processing of execution in step S11～S23 repeatedly, with average output current value Iave FEEDBACK CONTROL at target output current value Itar.
Under the situation of step S11 change target output current value Itar, the first instruction output current value I1 of the approaching target output current value Itar after changing of CPU52 decision and the second instruction output current value I2 (step S24).Under this situation, instruct output current value I2 to be set at the value up and down of target output current value Itar the first instruction output current value I1 and second.
Secondly, CPU52 is by following formula (3) decision duty ratio Rd (step S25).Thus, calculate the first control period ta and the second control period tb by following formula (2).Afterwards, CPU52 returns the processing of step S11, uses after changing the first instruction output current value I1, the second instruction output current value I2, duty ratio Rd, the first control period ta and the second control period tb processing of execution in step S11～S23 repeatedly.Thus, with average output current value Iave FEEDBACK CONTROL at after changing target output current value Itar.
(2-3) effect of power generation control 2
According to the power generation control 2 of second execution mode, the arbitrary value between the first instruction output current value I1 that the restriction of the control cycle T that target output current value Itar can be set at microcomputer 5 is made decision and the second instruction output current value I2.Thus, the average output current value Iave of three-phase mixed electrical bridge circuit 7 can be controlled at arbitrary value.Therefore, can be to the output current of electric loading and storage battery 3 supply arbitrary values.In addition, by at random changing target output current value Itar, can at random change the value of the output current of supplying with to electric loading and storage battery 3 according to two-wheeled 100 the state or the state of storage battery 3 etc.
