According to present embodiment, when starting as the ACG starter of starter motor, engine speed rises to regulation rotating speed (N
Ref3) time, interrupt starting, the monitor engine rotating speed, then, when engine speed is reduced to regulation rotating speed (N
Ref2) time, make the starting of ACG starter again, again turning crankshaft.So, can prevent the output shaft inordinate rotation, can pilot engine effectively.
As shown in Figure 5, Generation Control portion 400 also has from each phase stator coil of 2 pairs of ACG starters 1 of battery and lags behind energising to increase the function of generated energy (hereinafter referred to as " ACG switch on control ") except the function with common control generated energy (voltage).
Here said hysteresis energising is meant from the testing signal of rotor angle sensor 29 detected above-mentioned magnetization during with 33 pole change, postpones the electrical angle that is equivalent to stipulate, switches on to stator coil.But, in order to prevent engine revolution instability (this instability causes in the load rapid change that low Rotary District is produced by the action of regulator 100), the output voltage of full wave rectifier bridge circuit 300 (cell voltage) is controlled in the following assigned voltage scope of regulating voltage.
In Generation Control portion 400, engine speed judging part 48, according to for example testing signal of ignition pulse generator 30, the detection of engine rotating speed is if this engine speed in the Generation Control zone of regulation, is then supplied with driver 80 with the retardation angle instruction.Receive the driver 80 of retardation angle instruction, read the energising retardation angle amount that regulation is set from retardation angle amount configuration part 49, carry out the retardation angle energising.The energising dutycycle supplies to driver 80 from dutycycle configuration part 47.
Whenever rotor angle sensor 29 output magnetic pole signals, promptly, whenever sensor 29 detect the magnet ring 33 of answering with the pole pair of external rotor during tape, driver 80 detects the signal of beginning on.Then, from the quite amount of energising retardation angle that begins to lag behind of this signal, to each FET output pwm control signal of full wave rectifier bridge circuit 300.
Cell voltage judging part 46, the control voltage max VMaxt and the control voltage minimum VMin of cell voltage Vb and assigned voltage control range are compared, according to comparative result, increase and decrease is set in the energising load of dutycycle configuration part 47, and cell voltage Vb is housed in the above-mentioned control range.That is,, the energising load is only lowered the small value (for example 1%) of regulation if cell voltage Vb reaches control voltage max VMax.If cell voltage Vb reaches control voltage minimum VMin, will switch on loads only increases same small value (for example 1%).
Fig. 8 is the flow chart of the action of expression Generation Control portion 400, starts after the end of 500 pairs of engine start controls of above-mentioned starting control device.
At step S41, judge that whether engine speed is in the Generation Control zone.The Generation Control zone for example is set in below the above 3500rom of 1000rom.If engine speed is present in the Generation Control zone, then enter step S42, differentiate the sign F that the expression engine speed is present in the Generation Control zone
ACGWhether set up (=1).If sign F
ACGDo not set up, enter step S43, set up sign F
ACGAt step S44, specified value ACGAGL is set at the energising hysteresis.Specified value ACGAGL can suitably set in advance, for example is 60 ° of electrical angles in the present embodiment.
Then, at step S45, in energising load acduty, set initial value ACDUTY.This initial value ACDUTY also can suitably set in advance, for example is 40% in the present embodiment.Step S43～S45 enters step S47 after finishing.If certainly, then cross step S43～S45, enter step S47 at step S42.If above-mentioned engine speed will indicate F not in the Generation Control zone at step S46
ACGAfter removing (=0), enter step S47.
At step S47, judgement symbol F
ACGWhether set up.If sign F
ACGSet up, judge at step S48 whether cell voltage Vb is controlling more than the voltage max VMax.Control voltage max VMax is set at the value lower than regulating voltage, for example 13.5V.If cell voltage Vb more than control voltage max VMax, does not enter step S49, judge whether cell voltage Vb is controlling below the voltage minimum VMin.Control voltage minimum VMin for example is set at 13.0V.
At step S49, if cell voltage Vb not below control voltage minimum VMin, is judged as to enter and is located in the low ACG energising voltage range of ratio regulators regulating voltage, enter step S50, according to above-mentioned energising hysteresis acgagl and energising load acduty, carry out the ACG energising.
At step S48, if be judged as cell voltage Vb more than control voltage max VMax, enter step S51, the load acduty that will switch on only reduces small value DDUTY.Small value DDUTY for example is 1%.In addition, at step S49, if cell voltage Vb then enters step S52 below control voltage minimum VMin, the load acduty that will switch on only increases small value DDUTY.After the processing of step S52, S52, enter step S50.
In addition, increase and the above-mentioned small value acduty of load during aceuty that reduce to switch on can be inequality, also can be so that control voltage max VMax or control voltage minimum VMin change small value DDUTY with the difference of present value with being directly proportional.
At step S47, if sign F
ACGDo not set up,,, stop ACG energising control so enter step S53 owing to be not the Generation Control zone.
Fig. 9 is expression ACG when control energising, flows to the time diagram of the output of the electric current (phase current) of each phase of stator coil and rotor angle sensor 29.When not carrying out retardation angle control common, positive and negative (NS) that reply the detection output of rotor angle sensor 29 changes, and electric current supply is to U, V, each phase of W of stator coil.On the other hand, carry out retardation angle when control energising, when positive and negative (NS) of the detection output of rotor angle sensor 29 changed, the retardation angle amount d (=60 °) of the regulation that only lags behind was with electric current supply U, V, each phase of W to stator coil.
Among Fig. 9, the energising angle T of duty exchange conversion is 180 °, but also can utilize from the dutycycle configuration part the 47 energisings loads of supplying with drivers 80, at 180 ° with interior decision.
Figure 10 is engine speed Ne, is the figure of the rotating speed of ACG starter 1 as the energising load of parameter setting.The detection of engine rotating speed, decision as illustrated in fig. 8 and the engine speed load of switching on accordingly.
Like this,,, do not make common voltage regulator action, can stably increase generated energy at low rotary area according to the Generation Control of present embodiment.Therefore, when the idle running running waits, reduce the load change of motor, do one's utmost to reduce the change of engine revolution, can carry out stable idle running.
Again as shown in Figure 5, reverse rotation control device 700, the crankshaft torque when piloting engine in order to reduce improves engine start, after motor stops, crankshaft is reversed, and gets back to assigned position.
Stage is by time detecting portion 74, according to above-mentioned stage judging part 73 after judging the new stage to the time of judging before the next stage, detect the time of the passing through Δ tn in this stage.Reverse control device 75, the time of the passing through Δ tn according to the judged result of above-mentioned stage judging part 73 and above-mentioned stage are detected by time detecting portion 74 sends the reverse drive instruction.
Below, with reference to the flow chart of Figure 11 and the action specification figure of Figure 12, the action of above-mentioned reverse rotation control device 700 is described.Among Figure 12 (a), expression makes crankshaft 201 reverse the relation of required rotating crank axle moment (reversing load) and degree in crank angle.Rotating crank axle moment (during reverse) in front of compression top dead center sharply rises.Among Figure 12 (b), the expression degree in crank angle and the relation in stage.Among Figure 12 (c), the variation of the angular velocity of crankshaft when expression reverses.
At step S61, when detecting motor and stopping,, judge the stage of having been judged by stage judging part 73 now at step S62, S63.If during among stage # 0～#11 any, then enter step S64 when stage now.If during among stage # 12～#32 any, then enter step S65.If beyond above-mentioned when (promptly being any among stage # 33～#35), then enter step S66.At step S64, S66, in dutycycle configuration part 72, the dutycycle of driving pulse is set at 70%, in step S65, is set at 80%.
The dynamic control of this dutycycle as described later, during reverse, the angular velocity of the crankshaft 201 in the time of will reversing in front of the suitable angle of compression top dead center (during reverse) that rotating crank axle moment increases fully reduces, simultaneously, angle beyond it can reverse driving fast.
At step S67, each power FET of the dutycycle of the above-mentioned setting of driver 80 usefulness control full wave rectifier bridge circuit 300 begins to reverse energising.At step S68, Δ tn current"on"time of the stage #n that passes through passes through time detecting portion 74 by the above-mentioned stage and detects.
At step S69, in reversing control device 75, judge whether crankshaft 201 has passed through stage # 0, be near the upper dead center.If passed through stage # 0,, the time of the passing through Δ tn of the above-mentioned stage # 0 that just passed through is compared with reference value Rref (being 4/3 in the present embodiment) with the ratio (Δ tn/ Δ tn-1) of the time of the passing through Δ n-1 of the stage # (n-1) that passes through before at step S71.If above-mentionedly be no more than reference value Rref by time ratio (Δ tn/ Δ tn-1), then return step S62, reverse driving, above-mentioned repeatedly abreast therewith each handle.
The motor stop position, promptly reverse the initial position, be shown in curve A among Figure 12 (c), than last time with the side of the compression top dead center of neutral position more approaching next time of the compression top dead center of next time, in other words, be when having passed through exhaust top dead center (when just changeing) back to the process of arrival compression top dead center, although ACG starter 1 is reversed driving with 70% dutycycle, crankshaft still can pass through stage #0 (exhaust top dead center).Therefore, in step S69, detect this point, enter step S70, judge whether crankshaft 201 has arrived stage #32.Arrived stage # 32 if be judged as crankshaft 201, in step 72, above-mentioned reverse energising stops, and then, crankshaft stops after further reversing by inertial force.
Reverse the initial position, shown in curve B among Figure 12 (c), be than last time with the side of the more approaching compression top dead center last time in neutral position of the compression top dead center of next time, in other words, be by compression top dead center (just changeing) back during to the process of arrival exhaust top dead center, ACG starter 1 is reversed driving with 70% dutycycle, so, reverse load shown in Figure 12 (a), rise in the front (during reverse) that arrives stage # 0, the angular velocity of crankshaft 201 sharply descends.Then, at step S71, be judged as above-mentioned by time ratio (Δ tn/ Δ tn-1) when reference value 4/3 is above, at step S72, above-mentioned reverse energising stops, the reverse of crankshaft stops when stopping with switching on.
Like this, in the reverse rotation control device control of present embodiment, when the reverse after motor stops to drive, monitor whether crankshaft has passed through the suitable angle of upper dead center, and whether the angular velocity of crankshaft reduce, and during by upper dead center, finishes to reverse energising immediately when crankshaft reverses, when the angular velocity of crankshaft reduces because of the increase that reverses load, also finish to reverse energising.So, not only reversing the initial position, and crankshaft can turned back to last time (during reverse) in front of the compression top dead center, compress the low position of counter-force.
In addition, in the reverse rotation control device control of present embodiment, detect the angular velocity of crankshaft 201 according to the output of the rotor angle sensor 29 of the rotor angle (being the stage) that detects ACG starter 1, so, do not need to be provided in addition detecting the sensor of crankshaft angular speed.
According to the present invention, when detecting motor and reach the high engine speed of high order detonation state possibility, starter motor stops automatically, so, can prevent the high engine speeds unwanted crankshaft rotation that makes in back of exploding fully.In addition, owing to get the wrong sow by the ear based on the high order detonation of engine speed, engine speed is when reducing thereafter, and starter motor is restarted immediately.Therefore and since when the output speed and the engine air revolution of the motor of starter motor starting be same degree, even when being difficult to judge the high order detonation state, also can pilot engine effectively according to engine speed.
