Then, various sensors are described.In motor 12, be provided with crank angle sensor 51, temperature cylinder sensor 44, intake manifold pressure sensor 50 and intake air temperature sensor 45.Crank angle sensor 51 is that the rotation angle that is used to detect bent axle 46 is the sensor of crank position (crank phase).Temperature cylinder sensor 44 is sensors of the temperature of detection of engine main body 14.Here, temperature cylinder sensor 44 is made of temperature transducer, and this temperature transducer is used to detect the temperature of the cooling water that motor 13 is cooled off.In addition, temperature cylinder sensor 44 also can be the temperature transducer that detects the temperature of cylinder 13 itself.Intake manifold pressure sensor 50 is sensors of the internal pressure (suction press) that is used to detect suction tude 10.Intake air temperature sensor 45 is that the inside temperature that is used to detect suction tude 10 is the sensor of intake temperature.
Shown in Fig. 4 (a), ACM rotor 20 is installed on bent axle 46.In the periphery of ACM rotor 20, the predetermined interval of being separated by is provided with a plurality of (being 11 in the present embodiment) reluctor 60～70.At this, reluctor 60 and reluctor 70 be spaced apart 60 °, other reluctor each other be spaced apart 30 °.Near the periphery of ACM rotor 20, as crank angle sensor configuration pulser coil 51.If bent axle 46 rotations, then each reluctor 60～70 is by near the pulser coil 51, and the flux of pulser coil 51 changes.Thus, generate such pulse signal shown in Fig. 4 (b) as crank angle signal.In the present embodiment, detect crank position based on these pulse signals.In addition, based on interval (for example, the time lag between the rising edge of the pulse) T of these pulse signals, the instantaneous rotation period of detection of engine 12, calculation engine rotating speed.
As illustrated in fig. 2, crank angle sensor 51, temperature cylinder sensor 44, intake manifold pressure sensor 50 and intake air temperature sensor 45 are connected with ECU8.ECU8, from crank angle sensor 51, temperature cylinder sensor 44, intake manifold pressure sensor 50 and intake air temperature sensor 45, receive crank angle signal, cooling water temperature signal, suction press signal and intake air temperature signals respectively, control signal is outputed to petrolift 41, sparger 42 and spark coil 47 etc.
Fig. 3 is the block diagram by the constructed control system 100 of ECU8.This control system 100 possesses: engine speed calculating part 101, crank be detection unit 102 and suction air quantity calculating portion 103 regularly.
Engine speed calculating part 101 receives crank angle signal and the calculation engine rotating speed is exported the information relevant with engine speed.The inverse of engine speed is the engine rotation cycle.Therefore, engine speed calculating part 101, also the rotation period detector as the rotation period of detection of engine plays a role.
Crank is detection unit 102 regularly, receives suction press signal and crank angle signal, detects stroke state.Then, crank is detection unit 102 regularly, and information that will be relevant with stroke state is exported as the crank timing information.
At this, with reference to Fig. 5 (a)～(c) to by crank regularly the detecting method of detection unit 102 stroke state of carrying out describe.Fig. 5 (a) is the oscillogram of crank angle signal, and numbering " 0 "～" 10 " are respectively the pulses of reluctor 60～70.Fig. 5 (b), (c) represent suction press, stroke state etc. respectively.
In four-circulation motor, in the cycle period that air inlet, compression, expansion and exhaust constituted, bent axle 46 rotates twice.Therefore, only, aspirating stroke and expansion stroke can not be differentiated, in addition, compression stroke and exhaust stroke can not be differentiated by detecting crank position.On the other hand, by Fig. 5 (b) as can be known, suction press is different in aspirating stroke and expansion stroke, and is in addition, different in compression stroke and exhaust stroke.Therefore, by with crank position and suction press combination, can detect stroke state.
For example, shown in Fig. 5 (a), when detecting the 4th pulse signal, only, can not distinguish compression stroke or exhaust stroke by this pulse signal.But in exhaust stroke, because outlet valve 7 is opened and suction valve 6 cuts out, so suction press uprises.On the other hand, at the initial stage of compression stroke, because suction valve 6 is opened (perhaps, even suction valve 6 cuts out the influence of the aspirating stroke before also being subjected to), suction press step-down.Therefore, by taking into account tracheal pressure, can distinguish compression stroke and exhaust stroke and detect.
Suck air quantity calculating portion 103, receive the crank timing informations from crank timing detection unit 102, and then, receive intake air temperature signals and suction press signal, calculate and suck air quantity.It is relevant with engine loading to suck air quantity, therefore can be by sucking the load of air quantity detection of engine.Therefore, sucking air quantity calculating portion 103 also plays a role as the load sensor of detection of engine load.
As shown in Figure 6, suck air quantity calculating portion 103, possess: suction press detection unit 201, mass flow rate map memory section 202 and intake temperature detection unit 204.Suction press detection unit 201 detects suction press at predetermined crank position.Mass flow rate map memory section 202, storage detect the map of the mass flow rate that sucks air based on suction press.In the present embodiment, in mass flow rate map memory section 202, the suction press when intake temperature is 20 ° and the relation of mass flow rate are made map.
Suck air quantity calculating portion 103, also possess mass flow calculation portion 203 and mass flow rate correction portion 205.Mass flow calculation portion 203, the mass flow rate map of employing mass flow rate map memory section 202 is calculated and the detected corresponding mass flow rate of suction press.In addition, above-mentioned mass flow rate map, the mass flow rate during based on predetermined temperature (being 20 ° in the present embodiment) makes.Therefore, when the intake temperature of reality and above-mentioned predetermined temperature depart from, there is deviation sometimes between actual mass flow rate and the mass flow rate of being calculated.At this, mass flow rate correction portion 205, from the information of intake temperature detection unit 204 reception intake temperature, the mass flow rate that will be calculated in mass flow calculation portion 203 is revised based on detected intake temperature.
In the present embodiment, when the calculating that sucks air quantity, utilize lower dead center from compression stroke to suction press value with suction valve 6 closed period.That is, when opening suction valve 6, owing to the pressure in suction press and the cylinder is equal to substantially, so as long as know suction press, cylinder internal volume and intake temperature, just can the interior air quality of determining cylinder.But because suction valve 6 is not opened after the beginning of compression stroke for a long time, air might be come in and gone out in cylinder and between the suction tude 10 betwixt.Therefore, if ask the suction air quantity by the suction press before the lower dead center, then this suction air quantity might be different with the actual air quantity that is drawn in the cylinder.At this, in the present embodiment, adopt suction valve in 6 operating periods, particularly the suction press of compression stroke calculates the suction air quantity.In addition, in order further to improve calculation accuracy, also can consider the influence of burnt gas dividing potential drop, adopt relevant therewith engine speed, that implements to try to achieve by experiment revises accordingly with engine speed.
As shown in Figure 3, control system 100 also possesses: fuel injection amount configuration part 104 and injection pulse carry-out part 105.Fuel injection amount and fuel injection time based on engine speed and suction air quantity, are set in fuel injection amount configuration part 104.Injection pulse carry-out part 105 receives the crank timing informations from crank timing detection unit 102, exports to sparger 42: with fuel injection amount that sets by fuel injection amount configuration part 104 and the corresponding injection pulse of fuel injection time.
Fuel injection amount configuration part 104 possesses: target air-fuel ratio calculating part 108, fuel injection amount calculating part 109 and fuel variance model 110.Target air-fuel ratio calculating part 108 calculates target air-fuel ratio based on engine speed and suction press.Fuel injection amount calculating part 109, based target air fuel ratio and suction air quantity, computing fuel emitted dose and fuel injection time.Fuel variance model 110 is carried out utilization when fuel injection amount calculating part 109 computing fuel emitted doses and fuel injection time.Fuel variance model 110 also is used for configuration part 106 firing time described later.Therefore, in Fig. 3, with fuel variance model 110 and fuel injection amount calculating part 109 for the ease of understanding diagram separately.But, in fact, fuel variance model 110 and fuel injection amount calculating part 109 one.In addition, in fuel variance model 110, utilize above-mentioned engine speed, intake air temperature signals and cooling water temperature signal.
Fuel injection amount calculating part 109 and fuel variance model 110 for example, constitute as the block diagram of Fig. 7.At this, establishing the fuel injection amount that sprays in suction tude 10 from sparger 42 is M

As shown in Figure 3, control system 100 also possesses: firing time configuration part 106 and firing pulse carry-out part 107.Firing time, the configuration part 106, carried out decision that setting, the decision forbidden of igniting and the advance angle of firing time forbid etc., output firing time or igniting prohibition information.Firing time, configuration part 106 was also as carrying out that igniting is forbidden controlling and advance angle is forbidden the controller performance function controlled.Firing pulse carry-out part 107, from crank regularly detection unit 102 read the crank timing information, will with the corresponding firing pulses such as firing time that configuration part 106 sets by firing time, to spark coil 47 outputs.
Then, to firing time configuration part 106 concrete condition describe.Firing time, the configuration part 106, possessed: basic ignition Time Calculation portion 111, with the common fuel variance model 110 in fuel injection amount configuration part 104, cylinder in air fuel ratio calculating part (in Fig. 3, being expressed as A/F calculating part in the cylinder) 112, firing time correction portion 113, counter-rotating judging part 114, igniting forbid removing judging part 115, igniting and forbid/advance angle forbid processing division 116 and igniting forbid/advance angle forbids judging part 117.
Basic ignition Time Calculation portion 111, the target air-fuel ratio that engine speed of being calculated based on engine speed calculating part 101 and target air-fuel ratio calculating part 108 are calculated is calculated the basic ignition time.Particularly, basic ignition Time Calculation portion 111 by current engine speed and target air-fuel ratio, by the map retrieval etc., obtains and produces torque and become maximum firing time, with it as the basic ignition time.
Air fuel ratio calculating part 112 in the cylinder, based on the fuel influx of being calculated by fuel variance model 110 that in cylinder, flows into (equating) with by sucking the suction air quantity that air quantity calculating portion 103 is calculated, calculate air fuel ratio in the cylinder with requiring the fuel influx.Particularly, air fuel ratio calculating part 112 in the cylinder with suck the suction air quantity calculated in the air quantity calculating portion 103 divided by the cylinder fuel influx of being calculated in fuel variance model 110, calculates air fuel ratio in the cylinder.
Firing time, correction portion 113, based on: by crank regularly air fuel ratio and basic ignition time of being calculated in the detected crank timing information of detection unit 102, the cylinder of being calculated by air fuel ratio calculating part 112 in the cylinder, revise firing time by basic ignition Time Calculation portion 111.Particularly, firing time, correction portion 113, when air fuel ratio and target air-fuel ratio have a great difference in the cylinder in the initial stage of compression stroke, adopted air fuel ratio, engine speed and suction press in this cylinder, according to the expectant control map, set new firing time.
Igniting forbids/advance angle forbids judging part 117, (in addition, because engine speed is the inverse in engine rotation cycle, therefore also can replace engine speed with the engine rotation cycle based on engine speed.Below same.), crank timing information and suck air quantity, judge whether to cause engine inversion.Igniting forbids/advance angle forbids processing division 116, and in the time might causing engine inversion, forbids lighting a fire or forbids advance angle more than or equal to prearranging quatity.In addition, igniting forbid/advance angle forbids processing division 116, output igniting prohibition information.Counter-rotating judging part 114 based on suction press signal, engine speed, crank timing information and igniting prohibition information, judges whether motor reverses.Counter-rotating judging part 114 also plays a role as reverse rotation detector.Igniting forbids removing judging part 115, receives the counter-rotating information and the above-mentioned igniting prohibition information of self reversal judging part 114, judge whether to remove igniting and forbid, to igniting forbid/advance angle forbids that processing division 116 output igniting forbid releasing information.Forbid removing judging part 115, igniting by these counter-rotating judging parts 114, igniting to forbid/advance angle forbid processing division 116 and igniting forbid/advance angle forbids judging part 117, carry out following counter-rotating and prevent control.
Then, with reference to Fig. 8, the counter-rotating of present embodiment is prevented that control from describing.In addition, it is the part of engine ignition control that this counter-rotating prevents to control, and counter-rotating shown in Figure 8 prevents control routine, based on the signal from crank angle sensor 51, to each predetermined crank position or each scheduled time, carries out.In this control, at first, in step S1,, detect the rotation period of each predetermined crank position based on crank angle signal from crank angle sensor 51.Then, carry out step S2, obtain suction press at predetermined crank position, based on this suction press, the counter-rotating that calculating is used to light a fire forbids controlling, advance angle forbids controlling etc. prevents the threshold value of the rotation period controlled.In addition, control is forbidden in so-called igniting, be to be used to prevent the counter-rotating of motor and the control forbidding lighting a fire, so-called advance angle is forbidden control, though be to allow engine ignition, forbid the control of lighting a fire than the further angular advance of predetermined crank position (this position is not limited to compression top center).In step S3, relatively in step S1 resulting rotation period and in step S2 the size of resulting threshold value, carry out IGNITION CONTROL based on its magnitude relationship and handle.
Then, with reference to Fig. 9 the rotation period threshold calculations processing of above-mentioned steps S2 is described.In this processing, at first, in step S11, judge whether current crank position is positioned at predetermined crank position CRK1.Then,, then carry out step S12, obtain the information (being suction press in the present embodiment) of engine loading if current crank position is positioned at predetermined crank position CRK1.On the other hand, if current crank position is not positioned at predetermined crank position CRK1, then finishes this rotation period threshold calculations and handle.Like this, predetermined crank position CRK1 sets the timing that is used for the detection of engine load.Therefore, predetermined crank position CRK1 so long as be suitable for carries out the position that engine loading detects and gets final product, and is not defined as certain location.
As mentioned above, in the present embodiment, based on the load of suction press detection of engine.For according to the load of suction press detection of engine, preferred as predetermined crank position CRK1, the high position of coherence of selection suction press and engine loading.At this, for example, when 1 cycle period, suction press changed as shown in Figure 10, position P1 that can little suction press (vacuum pressure is big) was set at predetermined crank position CRK1 as suction press and the high position of engine loading coherence.In addition, the crank angle of the transverse axis of Figure 10 (Figure 12 described later, 19,20 too) is that reference position (crank angle=0 °) is represented with the compression top center.In the present embodiment, above-mentioned position P1 only sets one, also can set above-mentioned position P1 a plurality of.A plurality of by above-mentioned position P1 is set, can calculate and suck the integral value, differential value of the high suction press of air quantity coherence etc., adopt these value detection of engine loads.
After detecting engine loading, carry out the step S13 of Fig. 9, calculate the threshold value NTA of the rotation period of the threshold value NT of rotation period of the benchmark of forbidding as igniting and the benchmark forbidden as advance angle.Then, threshold value NT and NTA are described.
The plotted curve of Figure 11 is illustrated in and does not carry out lighting a fire when forbidding controlling, i.e. the laboratory data when fixing crank position is lighted a fire always.The transverse axis of this plotted curve is represented the suction press Pm of predetermined crank position CRK1 (for example position P1 of Figure 10), i.e. engine loading.The longitudinal axis of this plotted curve is represented the rotation period T of predetermined crank position.In the present embodiment, as shown in figure 12, with near the compression top center (for example, from compression top center preceding 40 ° to the compression top center) crank position CRK2 as above-mentioned predetermined crank position.Near the compression top center, also rotation period long period (in other words being lower period of rotating ratio) in the middle of 1 circulation of motor, with the coherence height of the generation of reversing.
The plotted curve of this Figure 11, expression when just changeing and during counter-rotating rotation period and the dependency relation of engine loading.According to Figure 11 as can be known, when engine loading is big more (when suction press Pm is big more), even short rotation period also easily causes counter-rotating.
In the present embodiment, the threshold value NT of the rotation period of the benchmark of forbidding as igniting is set in the minimum rotation cycle of engine inversion and maximum rotation that motor is just changeing between the cycle.With the relevant data of this threshold value NT, promptly relevant data with the combination of rotation period that causes reversing and suction press, for example being stored in advance igniting forbids/advance angle forbids in the judging part 117.These data both can be the data of trying to achieve by experiment, also can be the data that theoretical property derives.In addition, above-mentioned predetermined crank position CRK2 is not limited near the compression top center.So long as can distinguish the state that rotates and reverse clearly, the crank position of the judgement practicality that can think two condition, also can make predetermined crank position CRK2 is abundant forward position between the compression top center.
Become the threshold value NTA of the rotation period of the benchmark that advance angle forbids, being set at may be because of angular advance cause the reversing rotation period of the minimum that takes place.With the relevant data of this threshold value NTA, promptly with the relevant data of combination of rotation period that causes because of advance angle reversing and suction press, also being stored in advance for example igniting forbids/advance angle forbids judging part 117.These data are same, both can be based on the resulting data of experiment, also can be the data that theoretical property derives.At this, the predetermined crank position CRK3 when setting this threshold value NTA is set in the forward position (with reference to Figure 12) of crank position CRK2 when setting igniting and forbid the threshold value NT of usefulness.Threshold value NTA is conceived to the rotation period T of above-mentioned predetermined crank position CRK3 and sets, and the result considers the minimum rotation cycle of engine inversion and the maximum rotation cycle of just changeing, as being set because of advance angle causes the rotation period of the minimum of reversing.
Figure 13 is the plotted curve that is used for illustrating the setting example of threshold value NTA.Set in the example at this, above-mentioned crank position CRK3 is positioned at the preceding 30 ° position than above-mentioned crank position CRK2.The engine speed of crank position CRK3 is higher relatively than the engine speed of crank position CRK2, and therefore, threshold value NTA (with reference to block curve) is set at the value littler than threshold value NT.
In above-mentioned setting example, based on suction press Pm shown in Figure 13 and the correlogram of rotation period T, supposition may cause the rotation period that reverses, setting threshold NTA thus because of advance angle.But the establishing method of threshold value NTA is not limited to carry out based on supposition, also can carry out based on laboratory data.For example, determine predefined full aduance position, carry out the igniting of this advance angle position under various conditions, detection has or not counter-rotating at this moment.Then, can be based on this testing result, setting threshold NTA (with reference to the dashed curve NTA of Figure 13).
In addition, in step S13 when calculated threshold NT and NTA, also can prepare to be set with the table of the value that satisfies Figure 11 and each curve shown in Figure 13, adopt this table to carry out interpolative operation.Perhaps, in advance with threshold value NT and NTA as the function mathematical expressionization of engine loading (being suction press in the present embodiment), calculate based on these functions.Concrete computational methods about threshold value NT and NTA are not done any qualification.
Next, with reference to Figure 14 the IGNITION CONTROL processing of step S3 (with reference to Fig. 8) is described.In IGNITION CONTROL was handled, at first, in step S21, whether confirming lights a fire at current time was forbidden handling.As a result, forbid carrying out the igniting of step S22 and forbidding recovering judgment processing when middle being in igniting, then in step S23, judge whether to proceed this igniting and forbid.When being necessary that proceeding igniting forbids handling, finish this routine in the judged result of step S23.On the other hand, in step S21, be judged as not to be to be in and light a fire when forbidding in the processing, enter step S24.In addition, in step S23, be judged as and also enter step S24 when igniting is forbidden recovering.In step S24, light a fire have or not, the igniting judgment processing of the setting of firing time etc.
With reference to Figure 15 the concrete condition of the igniting judgment processing of step S24 is described.In this processing, at first, in step S31, judge whether current crank position is in the zone of forbidding judging that allows to light a fire.That is, in the present embodiment, in order to judge with the high position of coherence of counter-rotating and to improve the judgement precision, perhaps save unnecessary computing and improve the efficient etc. of processing, the judgement that igniting is forbidden is set in predetermined crank position scope and carries out.But, also can not limit judge allowing the zone, light a fire in zone arbitrarily and forbid judging.At this moment, can omit step S31.
In step S31, be in igniting and forbid judge allowing then entering into step S32 in the zone if be judged as current crank position.On the other hand, being judged as current crank position when not being in igniting and forbidding judge allowing in the zone, enter into step S33.
In step S32, relatively: detect rotation period T obtained in handling and the size of obtained threshold value NT in the rotation period threshold calculations of step S2 is handled at the rotation period of step S1 (with reference to Fig. 8).If rotation period T, then is judged as the possibility height of engine inversion more than or equal to threshold value NT, carry out the igniting of step S37 and forbid handling, finish this routine.On the other hand, during less than threshold value NT, enter step S33 at rotation period T.
In step S33, judge whether current crank position is in to allow to carry out in the zone that advance angle forbids judging.In addition, this step S33 also can omit equally with step S31.In step S33, be judged as current crank position when being in advance angle and forbidding judge allowing in the zone, enter step S34.On the other hand,, enter step S35, carry out the normal ignition processing, finish this routine being judged as current crank position when not being in advance angle and forbidding judge allowing in the zone.
In step S34, relatively: detect rotation period T obtained in handling and the size of obtained threshold value NTA in the rotation period threshold calculations of step S2 is handled at the rotation period of step S1.If rotation period T, then is judged as the possibility height that causes engine inversion because of advance angle control more than or equal to threshold value NTA, carry out step S36.In step S36, carry out: forbid advance angle control, light a fire in the fixed position that the nonreversible predetermined benchmark crank position of motor is lighted a fire and handle.But, be set at, when lighting a fire, light a fire in the position of this retardation angle side in the position of the retardation angle side of this benchmark crank position.When in step S34, being judged as rotation period T, carrying out advance angle control and also do not have the possibility that produces counter-rotating, enter into step S35 and carry out normal ignition and handle even be judged as less than threshold value NTA.
In this wise, in the present embodiment, at rotation period during less than predetermined the 1st threshold value, the crank position of the prespecified range that the 1st predetermined crank position before compression top center is later allows igniting, at rotation period more than or equal to above-mentioned the 1st threshold value and less than the time than big predetermined the 2nd threshold value of above-mentioned the 1st threshold value, the crank position of the prespecified range that the 2nd predetermined crank position behind above-mentioned the 1st crank position is later allows igniting, during greater than above-mentioned the 2nd threshold value, forbids igniting at rotation period.
Next, with reference to Figure 16 the igniting of step S22 (with reference to Figure 14) is forbidden that the concrete condition of recovering judgment processing describes.In addition, this processing is also carried out when engine inversion, and therefore, crank position shown below is the discernible crank position of ECU8, may be different with the crank position of reality.
In this processing, at first, in step S41, judge that malleation detects sign F
BFWhether be 1.This malleation detects sign F
BFIt is the sign whether the expression motor reverses.When engine inversion, because the exhaust in the firing chamber 32 is to suction tude 10 reverse inflows, so suction press is depicted as than normal high value.For example, under normal situation, suction press is smaller or equal to barometric pressure, but when engine inversion, suction press surpasses barometric pressure sometimes.At this, in the present embodiment,, make malleation detect sign F if suction press is more than or equal to predetermined threshold value (this threshold value is not limited to barometric pressure in addition) in 1 circulation of motor
BFBe 1, counter-rotating has taken place in the expression motor.
Detect sign F in malleation
BF=1 o'clock, carry out step S46, judge whether motor stops.Then, when motor stops, in step S47, removing igniting and forbid, finish this routine.On the other hand, when motor does not stop, forbidding, therefore directly finish this routine owing to be unsuitable for removing igniting.Like this, in the present embodiment, when detecting the generation counter-rotating, till stopping, forbidding by motor igniting.
In step S41, detect sign F in malleation
BFBe not 1 o'clock, enter step S42, detect current crank position and whether be arranged in predetermined crank position zone (be expressed as malleation at Figure 16 and detect the crank position zone).At this, will be scheduled to the crank position zone, be set at the crank position zone that is easy to according to the counter-rotating of suction press detection of engine.That is, be set at the crank position zone that the counter-rotating of motor and the coherence of suction press are high.In the judged result of step S42 is that current crank position is when being positioned at above-mentioned crank position zone, carry out step S43, in the time of in not being in above-mentioned crank position zone, improve judgement precision or omission unnecessary processing for fear of the low judgement of precision and improve whole treatment effeciency etc., directly finish this routine.
In step S43, judge engine inversion by said method.That is, judge that whether current suction press is more than or equal to predetermined threshold value., be judged as motor counter-rotating has taken place during at current suction press, carry out step S45 and make malleation detect sign F more than or equal to above-mentioned threshold value
BFBe 1.Then, till motor stops, proceeding igniting and forbid (with reference to step S46, S47).
On the other hand, in step S43, during less than above-mentioned threshold value, carry out step S44, judge whether current crank position is that the igniting of being scheduled to recovers crank position at current suction press.In addition, so-called igniting recovers crank position, even be to recover igniting also can not cause the crank position that reverses, for example is the predetermined crank position after leaning on than the compression top dead center.At this, igniting recovers crank position, is the position after leaning on than the crank position that the counter-rotating judgement finishes, and is the forward position of crank position of preparing than the igniting that can carry out next time.Recover crank position by such setting igniting, can guarantee to forbid handling the adequate time allowance that becomes till the state that can carry out again ignition process from lighting a fire.In step S44, be above-mentioned igniting when recovering crank position at current crank position, in step S47, remove igniting and forbids, finish this routine.On the other hand, not above-mentioned igniting when recovering crank position at current crank position, directly finish this routine.
In addition, above-mentioned step S1, S2, S21, S31～S34, by igniting forbid/advance angle forbids that judging part 117 carries out.Step S35～S37, S47, by igniting forbid/advance angle forbids that processing division 116 carries out.Step S23, S41, S44, S46 forbid removing judging part 115 by igniting and carry out.Step S42, S43, S45 are undertaken by counter-rotating judging part 114.
As mentioned above, according to present embodiment, owing to be not based on the rotation period of motor, light a fire and forbid control and be based on rotation period and suction press both sides, so when being difficult to cause counter-rotating, can be that benchmark is forbidden igniting with bigger rotation period (in other words being lower engine speed), when being easy to cause counter-rotating, can be that benchmark is forbidden igniting with less rotation period (in other words being higher engine speed).
For example, as shown in figure 17, then forbidding under the situation of igniting smaller or equal to predetermined rotational speed N s, even the original state C that can not reverse (with reference to enclosing in vain), the igniting that also can be under an embargo (forcing flame-out).With respect to this, according to present embodiment, owing to the rotating speed that becomes benchmark changes corresponding to suction press, so the pressure can avoid state C the time is flame-out.Therefore, can avoid unnecessary pressure to stop working, can carry out the higher igniting of degree of accuracy and forbid control.In addition, similarly, can avoid unnecessary advance angle to forbid, can carry out the higher advance angle of degree of accuracy and forbid control.
In the present embodiment, preestablish the threshold value NT and the NTA that may cause the rotation period that reverses, will be in the running of motor 12 detected rotation period and these threshold values NT and NTA compare, and judge forbidding of igniting or advance angle.Therefore, can be by fairly simple formation, carry out above-mentioned igniting and forbid that control and advance angle forbid control.
In addition, in the present embodiment, according to the relation that is associated between suction press and the suction air quantity, based on the load of suction press detection of engine.Therefore,, there is no need to be provided with in addition new sensor and be used for the detection of engine load for the motor 12 that possesses intake manifold pressure sensor 50, can be simply and detection of engine load at low cost.
In addition, in the present embodiment, if after forbidding igniting, the counter-rotating of detection of engine 12 then makes motor 12 stop to remove igniting afterwards and forbids.Therefore, can not cause the releasing of forbidding along with igniting and bring out counter-rotating, increase big burden can not for motor 12.
And then, in the present embodiment, after forbidding igniting, when nonreversible and suction press is less than predetermined value at motor 12, removes igniting and forbids.Therefore, under the situation that can not cause reversing, can recover from the igniting illegal state immediately, can avoid unnecessary pressure to stop working.
In addition, in the present embodiment, will become the rotation period that the benchmark controlled is forbidden in igniting, being set near the rotation period of the crank position the compression top center.Therefore, can improve the judgement precision of counter-rotating, can realize the higher igniting of reliability forbid control.
In the above-described embodiment, detect engine loading based on suction press.But, also can be based on this engine loadings of detection such as other parameters relevant with this load.For example, as illustrated in fig. 18, also can be provided with: detect the engine load sensor 49 or the direct Air flow meter 48 that sucks air quantity that detects of the aperture (hereinafter referred to as throttle opening) of closure 33, based on throttle opening or the load of suction air quantity detection of engine.
Based on the load of throttle opening detection of engine the time, preferably with the high crank position of throttle opening coherence be benchmark.In other words, preferred, be benchmark with the crank position high with sucking the air quantity coherence.For example, preferred, as shown in figure 19,, be set in above-mentioned predetermined crank position CRK1: in 1 circulation of motor, the position P2 in the crank position in the precalculated position that suction valve 6 is opened such with the high position of suction air quantity coherence.In addition, also can set a plurality of position P2, the integral value of the throttle opening that calculating is high with sucking the air quantity coherence, differential value etc. adopt these value detection of engine loads.
When directly detecting the suction air quantity by Air flow meter 48, as illustrated in fig. 20, preferably:, be set in above-mentioned predetermined crank position CRK1: the position P3 in the crank position in the precalculated position that suction valve 6 is opened such with suck the high position of air quantity coherence.In addition, also can set a plurality of position P3 this moment, the integral value of the suction air quantity that calculating is high with sucking the air quantity coherence, differential value etc. adopt these value detection of engine loads.
In addition, in the above-described embodiment, when whether the combination of judging rotation period and engine loading is the combination that causes reversing, detect rotation period, judge (with reference to Fig. 8) based on this rotation period.That is, whether judge rotation period, forbid igniting or advance angle based on this judged result more than or equal to predetermined threshold.But, also can the engine loading threshold value be set to each rotation period, whether judge engine loading more than or equal to this threshold value, forbid igniting or advance angle based on this judged result.
Forbid recovering (with reference to Figure 16) in the judgment processing in the igniting of above-mentioned mode of execution, being judged as current crank position in step S44 is to light a fire when recovering crank position, carries out step S47, directly removes igniting and forbids.But, also can remove igniting and forbid at the crank position (in other words, become igniting recovery crank position from crank position and begin) that recovers than igniting after crank position leans on through after the scheduled period.
According to the difference of the kind of ignition mechanism, also consider sometimes aspect the relation of hardware formation etc., directly to remove igniting and forbids then causing the unsettled situation of ignition operation.But, as mentioned above,, then can make the ignition operation of removing after igniting is forbidden stable if set time is poor till forbidding removing to igniting.
For example, shown in Figure 21 (a), exist sometimes: spark coil first side voltage, forbid beginning not being returned to the situation of predetermined reference value from igniting to through the scheduled time (stabilization time).If with the crank angle is that benchmark considers that the phase difference of then corresponding with this stabilization time crank angle changes because of engine speed, general engine speed is high more then big more.But, for example,, can guarantee to have sufficient phase difference B from spark coil first side voltage is stable by till igniting is forbidden removing, phase difference A being set through beginning from the malleation surveyed area, can make the ignition operation after igniting is forbidden removing stable.
Also can carry out igniting shown in Figure 22 and forbid recovering judgment processing, replace igniting shown in Figure 16 to forbid recovering judgment processing.In the processing of Figure 22,, carry out step S44 when in step S42, being judged as current crank position not when malleation detects in the crank position zone (malleation surveyed area).In step S44, be when lighting a fire the recovery crank position, to carry out step S48 when being judged as current crank position, judge that the malleation detection judges whether to finish.When the judged result of step S48 is "Yes", think that spark coil first side voltage is stable, and carry out step S47, remove igniting and forbid.On the other hand, when the judged result of step S48 is "No", directly finish this routine.
But, for example,, be applied in the power that motor 12 is just being changeed sometimes from the outside two-wheeled 1 when on downward-sloping slope, travelling etc.At this moment, can think, even temporarily produced counter-rotating before compression top center, also can motor 12 just changeed by being subjected to the power from the outside thereafter, continue just changes with maintaining the original state.But at this moment, suction press may take place sometimes less than predetermined threshold value (with reference to the step S43 of Figure 16), even actual moment produces counter-rotating, can not detect the problem of this counter-rotating.Therefore, detecting in the device of crank position based on crank pulse, existing sometimes: crank pulse when just changeing and the crank pulse when reversing mix, and the situation of misidentification crank position.
On the other hand, forbid recovering existing among the step S43 of judgment processing (with reference to Figure 16) in igniting: suction press is removed the situation that igniting is forbidden during less than threshold value subsequently.Therefore, might remove igniting based on the crank position of mistake forbids.At this, preferred, before igniting is forbidden removing, revise the operation of reseting that detects error.
For example, also can carry out igniting shown in Figure 23 forbids removing the igniting of handling step of replacing S47 and forbids removing.Forbid removing in the processing in this igniting, at first in step S51, judge whether to detect the pulse of pre-determined number.When the judged result of step S51 is "Yes", carry out step S52, judged whether to detect predetermined benchmark crank position.In addition, the crank position of benchmark for example can be set at the reluctor 60 of Fig. 4 and the position between the reluctor 70 etc.Then, when the judged result of step S52 is "Yes", detected benchmark crank position as new reference position (reseting operation), is carried out the detection of crank position once more.In addition, owing to can hold correct crank position,, remove igniting and forbid so carry out step S53.In addition, when the judged result of step S51 and S52 is "No", directly finish this routine.
In the above-described embodiment, engine loading is not limited to the load of motor itself, also can comprise external loading.In addition, also can be corresponding to external loading correction rotation period threshold value NT, NTA.For example, as external loading, can consider load of electrical generation, the loss load during from the load of drive system and cold machine.At this moment, also the correction factor (electrical load correction factor) that load of electrical generation produced can be made as K1, in the future the correction factor that load produced (driving system loads correction factor) of self-driven system is made as K2, the correction factor (machine temperature correction factor) that loss load during with cold machine is produced is made as K3, and threshold value NT or NTA are multiplied by these correction factors K1～K3.
As the parameter relevant with load of electrical generation, for example, can consider: the opening/close or load (duty) opening/closing of Generation Control conducting/disconnection, Headlamps (H/L) than the opening/close of the conducting/disconnection of the conducting/disconnection of, handle heater, direction finder, Stop Lamp, loudspeaker.As with from the relevant parameter of the load of drive system, for example also can consider clutch conducting/disconnection, the gradient, gear.As illustrated in fig. 24, also can be in advance with these parametric functionizations, pictorialization or mapization, these parameters are multiplied each other mutually or addition etc., calculate each correction factor K1～K3 thus.In addition, during the calculating of the loss load when cold machine, also can adopt oil temperature, water temperature to wait the dessert machine actuator temperature.
As discussed above, the present invention is applicable to the ignition control device of motor and possesses its vehicle.
