Embodiment
Hereinafter, embodiments of the present invention are illustrated referring to the drawings.In addition, in the following embodiments, it is contemplated that
Automatic two-wheeled cycle is as vehicle, in the automatic two-wheeled cycle, to pass through the manually operated speed change level by variable-speed motor of driver
It is fast to the structure switched between 5 speed in neutral gear and 1.
[embodiment 1]
In the vehicle 10 shown in Fig. 1, engine 11 be by the burning of fuel and powered internal combustion engine, such as it is known that
Sample, suitably possess Fuelinjection nozzle and igniter etc..
On engine output shaft 12, variable-speed motor 17 is connected to via the clutch apparatus 16 as Poewr transmission mechanism.
Clutch apparatus 16 is slip clutch, possesses one group of clutch mechanism, and the clutch mechanism is defeated with engine is connected to
The plectane (flywheel etc.) of the side of engine 11 on shaft 12 and the plectane for the side of variable-speed motor 17 being connected on variable-speed motor input shaft 21
(clutch disk etc.).By in clutch apparatus 16 two plectanes contact with each other, turn between engine 11 and variable-speed motor 17
The power delivery status (clutch connection status) of passing power, are mutually left by two plectanes, turn into engine 11 and speed change
The power off state (clutch dissengaged positions) that power transmission between machine 17 is cut off.Alternatively, it is also possible to being in variable-speed motor
17 inside sets the structure of clutch apparatus 16.
Variable-speed motor 17 is the hand gear machine for having multiple speed change levels.Variable-speed motor 17 will input from variable-speed motor input shaft 21
The power of engine 11 by the gear ratio of the speed change level of the manually operated switching by driver come speed change, to variable-speed motor output shaft
22 outputs.Speed change level is in the state of driver operates the clutch lever (diagram is omited) being located on the handlebar of vehicle, by gear
Pedal switches over operation.Trailing wheel (wheel 27) is connected on variable-speed motor output shaft 22.
In addition, in the present system, possesses the Engine ECU (hereinafter referred to as ECU30) of the running status of control engine 11
As vehicle-mounted controlling organization.ECU30 is the known electronic-controlled installation for possessing microcomputer etc., based on being located at the system
In the testing result of various sensors etc. be appropriately carried out the control of engine 11.
As sensor class, the accel sensor provided with the detection accelerator opening being located on accelerator handle
41st, the throttle opening sensor 42 of the aperture for the detection air door being located on the air intake duct of engine 11, the suction for detecting engine 11
The air-breathing pressure sensor 43 of endotracheal pressure, the rotation speed sensor 44 for detecting engine rotary speed, each sensor
Detection signal is sequentially inputted in ECU30.In addition, sensor 41~43 can start equivalent to load sensor from detection
Machine load this point sets some of which.
Testing results of the ECU30 based on various sensors, implement the combustion of the amount for the fuel that control is sprayed by Fuelinjection nozzle
Expect emitted dose control and control the various engines of the IGNITION CONTROL of igniting carried out by igniter etc. to control.In addition, this reality
The ECU30 for applying mode arrives the resume of engine rotary speed in storage part (diagram is omited) with time series storage, according to the hair
The resume of motivation rotary speed judge the presence or absence of implementation of gear change and gear position.
Here, the decision method of the presence or absence of the gear change that is carried out by ECU30 is illustrated.Fig. 2 is to represent that gear becomes
The explanation figure with the relation of engine rotary speed is changed, when (a) represents upshift, when (b) represents downshift.In Fig. 2 (a), moment t1
It is to carry out driver in Fig. 2 (b), during moment t3~t4 during~t2 during being the shift-up action for carrying out driver
Shift-down action during.
If carrying out gear change, the combination (combination of pitch wheel) of the gear of variable-speed motor 17 is gear ratio
Switching, so the engine rotary speed before and after gear change significantly changes.In the present embodiment, based on along with so
The dynamic testing result of engine rotary speed of gear change judge the presence or absence of gear change.
Specifically, detection informations of the ECU30 based on rotation speed sensor 44 calculates engine rotary speed NE1, and
By the way that engine rotary speed NE1 to be passivated to (annealing, smooth, annealing) processing, passivation rotary speed is calculated
NE2.In the case, engine rotary speed NE1 is the original value of engine rotary speed, in contrast, passivation rotation speed
Degree NE2 is the value for the change passivation for making original value.Being passivated rotary speed NE2 for example can be by using defined deactivation constant a1
(<1) the passivation computing shown in following formula (1) is repeated with specified period to calculate.
NE2=(1-a1) × NE2+a1 × NE1 ... (1)
That is, the previous value for being passivated rotary speed NE2 will be multiplied by the value after (1-a1), with to engine rotary speed NE1
This sub-value be multiplied by the value after a1 and be added, its result is set to be passivated to rotary speed NE2 this sub-value.In addition, can also
Structure of the filtering process for implementing LPF etc. as Passivation Treatment is made, by by engine rotary speed NE1 filtering
Reason is passivated rotary speed NE2 to calculate.
Also, ECU30 subtracts engine rotary speed NE1 from passivation rotary speed NE2, rotation variation Δ NEA is calculated
(Δ NEA=NE2-NE1).
It is engaged gears state before moment t1 in Fig. 2 (a), under the engaged gears state, is not susceptible to engine rotation
The rotation for turning the state sudden turn of events changes, and rotation variation Δ NEA turns into smaller value, i.e., the value near 0.If in contrast,
Upshiftd, then the change of gear ratio occurs, so engine rotary speed NE1 precipitous change occurs in moment t1~t2
Gradient.In the case, in upshift, the state risen and engine rotary speed NE1, hair are connected from by accelerator
The anxious of engine rotary speed NE1 that the raw change tape because of gear ratio comes declines, so after gear change starts, rotation changes
Amount Δ NEA sharp increases.Here, exceed defined threshold alpha by rotating variation Δ NEA, upshift can have been made only
Judge.
In addition, the gear change of the comparison based on rotation variation Δ NEA and threshold alpha judges also to can be used in by from speed change
The gear of machine 17 switches to the judgement during engaged gears state of engaged gears without the neutral state of occlusion.
In addition, in Fig. 2 (b), it is engaged gears state before moment t3, under the engaged gears state, is not susceptible to send out
The rotation of the motivation rotation status sudden turn of events changes, and rotation variation Δ NEA turns into smaller value, i.e., the value near 0.Relative to
This, if downshifted, occurs the change of gear ratio, so the steep of engine rotary speed NE1 occurs in moment t3~t4
High and steep variable gradient.In the case, in downshift, decline and engine rotary speed NE1 from being disconnected by accelerator
State, occur by the change tape of gear ratio Lai the anxious of engine rotary speed NE1 rise, so starting in gear change
Afterwards, rotation variation Δ NEA is sharp reduced.Here, it is less than defined threshold value beta by rotating variation Δ NEA, can makes
The judgement to be downshifted.
In addition, under neutral state, due to compared with engaged gears state, the engine rotary speed when accelerator is connected
Easily rise, so in terms of engine rotary speed NE1, passivation rotary speed NE2 easily becomes smaller value.That is, rotate
Variation Δ NEA easily turns into larger value to minus side.Therefore, it is possible to unexpectedly occur along with as Δ NEA<β tooth
The misinterpretation of round transformation.
So in the present embodiment, in the case where being neutral state, by be engaged gears state situation phase
Than making the degree of passivation of passivation computing diminish, realizing the misinterpretation of gear change prevents.Specifically, in engaged gears state
Under, deactivation constant a1 is used in the passivation computing of above-mentioned formula (1), under neutral state, using blunt compared with deactivation constant a1
The small deactivation constant a2 of change degree.Here, it is a1<a2<1.Illustrated by Fig. 3.
In figure 3, NE2 (a1) is the passivation rotary speed calculated using deactivation constant a1, is represented with single dotted broken line.This
Outside, NE2 (a2) is the passivation rotary speed calculated using deactivation constant a2, is represented with thick dashed line.Variation Δ NEA is rotated,
It is corresponding with NE2 (a1) to be represented with single dotted broken line, it is corresponding with NE2 (a2) to be represented with thick dashed line.
In figure 3, due to having used deactivation constant a1 passivation rotary speed NE2 (a1) relative to engine rotary speed
NE1 rising and more gently rise, it is possible to turn into Δ NEA before gear change as illustrated<β.Relative to
This, according to the passivation rotary speed NE2 (a2) for having used deactivation constant a2, becomes even if same engine rotary speed NE1 rises
Change and also suppress to turn into Δ NEA<β.
In addition, engine rotary speed NE1 is due to gear change and beyond changing, it is also possible to according to its of interference etc.
His factor and change.For example, driver is singly carry out clutch disconnected without gear change under accelerator on-state
In the case of opening/connecting, due to engine rotary speed NE1 precipitous variable gradient occurs, so even if not entering actually
Row gear change, it is also possible to it is misjudged be set to carried out gear change.But if unactual carry out gear change, just not
The front and rear engine rotary speed NE1 that the change based on gear ratio occurs change is cut off in clutch.
In the present embodiment, in the case where being judged to having carried out gear change based on rotation variation Δ NEA, calculate
The difference of engine rotary speed NE1 before and after gear change is changed as rotary speed variation delta NEB based on the rotary speed
Δ NEB is measured, the result of determination for judging gear change is effective or invalid.Specifically, rotary speed variation delta NEB passes through
Engine rotary speed NE1 before clutch cut-out (that is, when clutch is connected) subtracts (that is, clutch after clutch cut-out
During disconnection) engine rotary speed NE1 calculate.
If illustrated using Fig. 4, with gear change and feelings that engine rotary speed NE1 is changed
Under condition (A of reference picture 4), the front and rear rotary speed variation delta NEB of the clutch cut-out of the change based on gear ratio is calculated.Separately
On the one hand, it is no progress gear change in the state of engine rotary speed NE1 there occurs change in the case of (reference picture 4
B), the front and rear rotary speed variation delta NEB of clutch cut-out essentially becomes 0.
In the present embodiment, rotary speed variation delta NEB absolute value less than setting γ in the case of, be based on
Variation Δ NEA is rotated, the result of determination for having gear change is set to invalid.In the example in fig. 4, in the case of A, gear
The result of determination of conversion is effective, in contrast, in the case of B, the result of determination of gear change is invalid.In addition, it is specified that
Value γ can be based on experiment etc. and preset.
Then, the gear change determination processing that ECU30 is performed is illustrated using Fig. 5 and Fig. 6 flow chart.In addition,
Following each processing is implemented repeatedly in the state of the ignition switch for eliminating diagram is switched on specified period.
In managing in this place, judge whether previous gear position is neutral gear (S11) first.Present treatment is in previous processing
It is judged to affirming when gear position is neutral gear.In addition, the details that neutral gear judges illustrates in S18.
Be determined as in S11 it is previous be neutral gear in the case of, using deactivation constant a2 calculate passivation rotary speed NE2, and
And engine rotary speed NE1 is subtracted from passivation rotary speed NE2, calculate rotation variation Δ NEA (S12).It is determined that
Whether the rotation variation Δ NEA calculated in S12 is more than threshold alpha (S13).In the case where S13 is negative, it is determined as
Neutral state is maintained (S14).
S13 for affirmative in the case of, i.e., in the case of Δ NEA≤α, judge gear change condition for validity whether into
Vertical (S15).In present treatment, calculate be judged as Δ NEA≤α it is front and rear (that is, turn into Δ NEA≤α it is tight before and once into
To turn into Δ NEA after Δ NEA≤α again<α's is next) rotary speed variation delta NEB, and the rotary speed change
Amount Δ NEB absolute value be it is more than setting γ in the case of, be set to gear change and judge it is effective.In the feelings that S15 is affirmative
Under condition, it is judged to being switched for 1 fast (S16) from neutral gear.In the case where S15 is negative, S14 is proceeded to, is determined as neutral gear
State is maintained.In addition, the deactivation constant a2 under neutral gear is set to the deactivation constant a1 than being used under engaged gears state
Big value (in other words, the less value of degree of passivation) so that do not turn into rotation variation Δ NEA under neutral gear<Threshold value beta.
S11 for negative in the case of, i.e., previous gear position be 1 speed~5 speed some and be engaged gears shape
In the case of state, neutral gear judgement (S17) is carried out.Here, on being neutral state, based on engine rotary speed NE1 and start
Machine load is judged.
Neutral gear determination processing is represented in figure 6.First, judge whether engine rotary speed NE1 is idling rotary speed
(S31).In the case of by S31 affirmatives, determine whether to turn into the fully closed state (S32) of air door.In present treatment, based on wind
In the case that the testing result of door jaw opening sensor 42 is determined as that air door is fully closed, or in the detection based on air-breathing pressure sensor 43
Result judgement be as state is uncharged in the case of, be judged to turning into the fully closed state of air door.In the situation that S32 is affirmative
Under, determine whether to have passed through the stipulated time (S33) certainly from S32.Also, in the case where S33 is affirmative, judgement is empty
Shelves (S34).In some of S31~S33 for negative in the case of, be determined as be not neutral gear but engaged gears state (S35).
, can also be when some of S31 and S32 conditions continue for the stipulated time beyond above-mentioned, judgement is neutral gear.This
Outside, the fully closed state of air door can also be determined to be based on being disconnected as accelerator in S32.In addition it is also possible to based on pair
Should in engine load (testing result of air-breathing pressure sensor 43 etc.) change and engine rotary speed NE1 excessively rises to
More than fixing speed, it is determined as it being neutral gear.
Then, Fig. 5 is returned to, whether the result judgement based on S17 has been transferred to neutral gear (S18).It is being judged to being transferred to
In the case of neutral gear, gear position is reset (S26).
It is being determined as not being neutral gear but in the case of engaged gears state, passivation rotation speed is calculated using deactivation constant a1
NE2 is spent, and rotation variation Δ NEA (S19) is calculated according to the passivation rotary speed NE2 and engine rotary speed NE1.So
Afterwards, judge whether rotation variation Δ NEA is more than threshold alpha (S20).In the case where S20 is affirmative, gear change is judged
Whether condition for validity is set up (S21).It is same with S15 processing in present treatment, the rotation before and after Δ NEA≤α is judged as
Rotary speed variation delta NEB absolute value be it is more than setting γ in the case of, it is believed that gear change judge be effective.
In the case that S21 is affirmative, it is determined as it being upshift (S22).In the case, such as to previous gear position add 1 grade, be set to
Current gear position.
In the case where S20 is negative, Δ NEA is determined whether<β(S23).In the case where S23 is affirmative, tooth is judged
Whether the condition for validity of round transformation is set up (S24).In present treatment, Δ NEA is being judged as<The front and rear of β (that is, will turn into Δ
NEA<Before β is tight and once turning into Δ NEA<After β again turn into Δ NEA≤β it is next) rotary speed variation delta NEB it is absolute
Value be it is more than setting γ in the case of, it is believed that gear change judge be effective.In the case where S24 is affirmative, judgement is
Downshift (S25).In the case, such as by previous gear position subtract 1 grade, be set to current gear position.In addition, S21,
In the case that S23, S24 is negatives, it is believed that the previous value of gear position is kept without gear change.
[embodiment 2]
In above-mentioned embodiment 1, following structure has been made：Based on as engine rotary speed NE1 and passivation rotation
Rotary speed NE2 poor rotation variation Δ NEA is determined as the precipitous variable gradient there occurs engine rotary speed NE1
In the case of, judge carried out gear change.In contrast, in the present embodiment, based on being sent out in engine rotary speed NE1
Variable gradient more than regulation gradient is given birth to and then there occurs the increase and decrease of the engine rotary speed NE1 in specified time limit
Repeatedly, the presence or absence of gear change is judged.
In addition, in the case where being judged to having carried out gear change, the engine rotary speed before and after gear change is calculated
NE1 difference is as rotary speed variation delta NEB, based on rotary speed variation delta NEB, the speed change level of judgement variable-speed motor 17
Rise or dropped.
The detailed change of engine rotary speed NE1 when illustrating upshift operation using Fig. 7.Upshift when, by by
Driver is by clutch rupturing operation (opening operation), the engine rotary speed NE1 suddenly risings as P1.Also, in clutch
Device carries out upshift operation in disconnecting, then, with by clutch connecting operation, under the engine rotary speed NE1 urgency as P2
Drop.Subsequently, by carrying out half-clutch device operation, engine rotary speed NE1 increase and decrease occurs as P3 repeatedly.
Here, the sudden turn of events of the engine rotary speed NE1 at P1 and P2 can the differential based on engine rotary speed NE1
Value turns into more than setting to judge.In addition, engine rotary speed NE1 and passivation rotary speed NE2 can also be based on
Difference judge the engine rotary speed NE1 sudden turn of events.The sudden turn of events of the engine rotary speed NE1 at P2 is judged, equivalent to sentencing
It is scheduled in engine rotary speed NE1 that there occurs variable gradient more than regulation gradient.
In addition, it is illustrated that omit, but due to the state disconnected in downshift as accelerator, so even if clutch disconnects,
It is not easy to occur the sudden turn of events of the engine rotary speed NE1 along with clutch disconnection.But with after downshift operation from
Clutch connects, and engine rotary speed NE1 suddenly rises, also, engine rotation then occurs by carrying out half-clutch device operation
Speed NE1 increase and decrease is repeatedly.
Fig. 8 is the flow chart for representing gear change determination processing, and present treatment is replaced by above-mentioned Fig. 5 processing, by ECU30
Implement.
In fig. 8, carry out neutral gear judgement (S41) first, be determined as be neutral state in the case of (in S42 for yes
In the case of), gear position is reset (S43).The processing of the S41~S43 is and Fig. 5 S17, S18, S26 identical is handled.
In addition, be determined as not being neutral gear but in the case of engaged gears state (S42 for no in the case of), implement from
The processing (S44) that clutch operation judges.It is based on the engine rotary speed NE1 being illustrated in Figure 7 that the clutch operating, which judges,
Change dynamic come what is carried out, represent its order in fig.9.During namely based on engine rotary speed NE1 to upshift or when downshifting
The change of defined variation patterns, judge the presence or absence of clutch operating.
In fig.9, determine whether to have carried out clutch disconnection, i.e., whether there occurs the engine disconnected along with clutch
The rotary speed NE1 sudden turn of events (S51).In addition, the NE1 disconnected along with clutch the sudden turn of events (anxious to rise) is when upshifing
, only it can implement S51 in upshift.In addition it is also possible to S51 is omitted.In the case where S51 is affirmative, determine whether to send out
Give birth to and increased along with the engine rotary speed NE1 of the attended operation of clutch urgency or suddenly subtract (S52).
In the case where S52 is affirmative, determine whether engine rotary speed NE1 it is anxious increase or it is anxious subtract after there occurs by
Carry out the increase and decrease (S53) for the engine rotary speed NE1 that half-clutch device operation is brought.Present treatment is in engine rotary speed NE1
Increase and decrease by more than stipulated number repeatedly when affirm.In the case where S53 is affirmative, it is determined as there is gear change (S54).
In the case that S51~S53 is negative, it is determined as no gear change (S55).
Fig. 8 is returned to, after clutch operating judgement, based on its result of determination, determines whether that there occurs gear change
(S45).Also, in the case where being judged to having gear change, calculate the engine rotary speed NE1 before and after gear change
Difference, as rotary speed variation delta NEB (S46).Now, from the NE1 before gear change subtract gear change after NE1, meter
Calculate rotary speed variation delta NEB.
Then, it is determined that whether it is on the occasion of (S47) for rotary speed variation delta NEB.In the case where S47 is affirmative, sentence
It is upshift (S48) to be set to.In the case, such as to previous gear position 1 grade is added, is set to current gear position.This
Outside, in the case where S47 is negative, it is determined as it being downshift (S49).In the case, such as by previous gear position 1 is subtracted
Level, is set to current gear position.In addition, in the case where S45 is negative, it is believed that without gear change, keep gear position
Previous value.
In addition, in Fig. 8 processing, can also be same with Fig. 5, make and judge whether the condition for validity of gear change is set up
Structure.In the case, it is same with Fig. 5 S15 processing such as after S46, it is put into the rotation judged before and after gear change
Whether velocity variable Δ NEB absolute value is more than setting γ processing.And it is possible to it is set to | Δ NEB |≤γ's
In the case of gear change judge it is effectively, in | Δ NEB |<It is invalid that gear change, which judges, in the case of γ.
[other embodiment]
More than, embodiments of the present invention 1 and 2 are illustrated, but the purport of the present invention can also not departed from
In the range of in the form of various implement.For example, it is also possible to implement each form as shown below.
(1) as described above, before and after gear change, velocity variable is rotated in engine rotary speed NE1
Δ NEB, but Δ NEB have under the conditions of defined to gear position it is related.For example, under conditions of speed is certain, gear
Position (series) is smaller, and rotary speed variation delta NEB is bigger.So such gear position and rotation speed can also be utilized
Degree variation delta NEB dependency relation judges gear position.
The relation of engine rotary speed NE1 change and the change of gear position (speed change level) is represented in Fig. 10.Figure
10 represent change of the speed change level with engine rotary speed NE1 during 1 fast → 2 fast → 3 fast → 4 fast → 5 speed change.
In Fig. 10, the rotary speed variation delta NEB before and after gear change is when speed change level changes so that 1 speed → 2 are fast
Δ N1, speed change level with 2 speed → 3 speed change when be Δ N2, speed change level with 3 speed → 4 speed change when be Δ N3, speed change level with
It is Δ N4 during 4 speed → 5 speed change.In the case, Δ N1~Δ N4 is on the occasion of based on this, being judged to being upshiftd.Separately
Outside, it is illustrated that omit, but Δ NEB is negative value in the case of downshift, is judged to being downshifted based on this.
Δ N1~Δ N4 corresponds respectively to the change of gear ratio and is different values, e.g. Δ N1>ΔN2>ΔN3>Δ
N4.In the case, rotary speed variation delta NEB changes according to the series of variable-speed motor 17, before depending on gear change
The change of the gear when gear ratio after gear change, speed change level i.e. before and after gear change.So by before and after gear change
The change of speed change level and the relation of the rotary speed variation delta NEB before and after same gear change are redefined for relation data,
Using the relation data, the speed change level after gear change is judged based on each rotary speed variation delta NEB.
For example, in above-mentioned Fig. 5 or Fig. 8, in the case where being judged to having gear change, being upshiftd or downshifted, make
With above-mentioned relation data, gear position is determined based on each rotary speed variation delta NEB.
(2) in above-mentioned, it is determined as in Fig. 6 S34, Figure 11 S64 after being neutral gear, can also be in engine load
In the state of being changed in (throttle opening or pressure of inspiration(Pi)), become the feelings smaller than regulation change in engine rotary speed
Under condition, it is determined as that gear is switched to 1 speed.That is, by from neutral gear switch to 1 it is fast when, on one side gradually by air door open on one side general
Clutch engages, so when such condition is set up, can determine that to be switched to 1 speed.
(3) in above-mentioned, the poor rotation used as engine rotary speed NE1 and passivation rotary speed NE2 is illustrated
Change momentum Δ NEA to judge the example of gear change.In addition, engine rotary speed NE1 differential can also be used
Value or the difference of engine rotary speed NE1 and its differential value judge gear change.Or these computings can also be distinguished
Combination, to judge gear change.
(4) in above-mentioned, can also carried out by the speed change of gear change it is next, gear change will be carried out again
Possibility it is relatively low during be set as shielding during.Such as in the figure 7, it is fast being rotated there occurs the engine occurred during upshift
Spend during being shielded as defined in (P3) repeatedly of NE1 increase and decrease next setting.If so, then carrying out passing through gear change
Speed change it is next, because interference etc. influence and engine rotary speed change when, it is gear change surely that can avoid misjudged.
(5) in above-mentioned, Fig. 6 neutral gear can also be judged to implement with Figure 11 order.Specifically, wind is judged first
Whether door aperture has changed (S61).Present treatment is in the detection value changes of the throttle opening obtained by throttle opening sensor 42
Certainly.In the case where S61 is affirmative, engine rotary speed NE1 variable quantity (S62) is calculated.For example, calculate the micro- of NE1
Variable quantity of the score value as engine rotary speed NE1.Then, based on the engine rotary speed NE1's calculated in s 62
Variable quantity, judges whether engine rotary speed NE1 excessively rises more than fixing speed (S63).At this time it is also possible to according to wind
The variable quantity of door aperture, it is variably set NE1 excessive rising decision content.Also, in the case where S63 is affirmative, it is determined as
Gear position is neutral gear (S64).On the other hand, in the case where S61, S63 is negatives, it is determined as not being neutral gear but gear is stung
Conjunction state (S65).
(6), can also be with engine load (such as pressure of inspiration(Pi)) for necessarily (variable quantity is not in above-mentioned Fig. 5, Fig. 8, Fig. 9
To regulation variable quantity) it is condition, judge the presence or absence of gear change.That is, if it is conceived to the speed before and after gear change and starts
Machine load does not change, then engine rotary speed when identical load (pressure of inspiration(Pi)) occurs is different.Therefore, it is possible to according to rotation
Speed difference calculates gear ratio to speculate gear position.In addition, present treatment is preferably in the next implementation of gear change.By in tooth
The next implementation of round transformation, the supposition of gear position can be suitably carried out in speed and pressure of inspiration(Pi) identical region.
(7) it can also be determined as it being downshift in Air suction pipe pressure when being declined to become more than setting.
(8) in above-mentioned, the series of gear can not also be judged, and judge be upshift (high gear), downshift (low gear),
Neutral gear which kind of.
(9) present invention is also applicable to the control by ECU30 come in the automatic transimission of change gear position.This
Outside, the present invention is applicable in the various vehicles or machinery for being equipped with engine, such as can be carried out to four-wheel automatic vehicle, production
The application of the agricultural machinery of the construction implement of industry vehicle, crane locomotive etc., tractor etc. etc..It is further possible to it is applied to
In the engine used in the energy supply system of cogeneration of heat and power etc..
(10) in above-mentioned, the determination processing of downshift can also be made turn into invalid in neutral gear.For example, in above-mentioned Fig. 2,
Without the judgement of the threshold value beta using downshift side.In the case, the mistake of the gear change (downshift) under neutral gear can also be avoided
Judge.
(11) in above-mentioned, the adding provided with the operational ton (accelerator opening) for detecting accelerator handle in automatic two-wheeled cycle
In the case of fast device sensor, the testing result of the accelerator opening obtained by accelerator sensor can also be used to judge tooth
Take turns position.For example, it is also possible to the degree of engine rotary speed NE1 corresponding with accelerator opening rising is added, to judge
Gear position.
[action effect]
According to above-mentioned embodiment 1 and 2 and other embodiment, following good effect can be played.
(1) when carrying out the gear change of variable-speed motor 17, generation cause is in the engine rotary speed of the change of gear ratio
Precipitous variable gradient.In the case, precipitous variable gradient based on engine rotary speed judges gear change
The presence or absence of, even if so as to without using gear position sensor or wheel speed sensor etc., also can be with simple structural determination tooth
The presence or absence of round transformation.
(2) when carrying out gear change, when the acceleration and deceleration of the vehicle 10 in the state of engaged gears compared with, engine rotation
The variation quantitative change of rotary speed is big.Particularly, when being upshiftd when in the acceleration of vehicle 10, the rotary speed along with upshift occurs
It is anxious to decline.In addition, when downshifting when in the deceleration of vehicle 10, occur to rise along with the anxious of rotary speed of downshift.So
In the case of, because the passivation rotary speed NE2 of engine rotary speed prolongs relative to detected value (engine rotary speed NE1)
Change late, so engine rotary speed NE1 temporarily suddenly increases with being passivated rotary speed NE2 speed difference Δ NE.Pass through profit
With the feature, the presence or absence of gear change can be suitably judged.
(3) under neutral state, compared with engaged gears state, when accelerator is connected, engine rotary speed is easily anxious
Rise, the misinterpretation of gear change easily occurs due to precipitous variable gradient occurs.On this point, due to being tied to be following
Structure, make degree of passivation small to calculate passivation rotary speed NE2, so can under neutral state, compared with engaged gears state
Realizing the misinterpretation of gear change prevents.
(4) it is contemplated that under clutch off-state gear change operation after, in order to smoothly to clutch connect
State switches and carries out half-clutch device operation.In the case, engine rotary speed NE1 increase and decrease occurs within specified time limit
Repeatedly.Thus, by being determined as that there occurs engine rotary speed NE1 precipitous variable gradient and subsequent engine
Rotary speed NE1 increase and decrease repeatedly, can suitably judge the presence or absence of gear change.
(5) under engaged gears state, compared with gear is without the neutral state of occlusion, connected in the accelerator of driver
When be not susceptible to the anxious rising of engine rotary speed.Therefore, by using be engaged gears state as condition, based on rotation change
Measure Δ NEA and judge the presence or absence of gear change, the judgement precision thus, it is possible to improve gear change.
(6) when having carried out gear change, according to the change of gear ratio, occur engine rotary speed to increase side or
Reduce the change of side.Thus, according to the variable quantity of the front and rear engine rotary speed of gear change, can determine that as variable-speed motor
17 speed change level rises or dropped.
(7) variable quantity of the engine rotary speed before and after gear change corresponds to the series of variable-speed motor 17 and changed, according to
The change for the speed change level being stored in before and after gear ratio of the gear before gear change when after gear change, i.e. gear change.Pass through
Using this point, the speed change of variable-speed motor 17 can be judged based on the poor size of the engine rotary speed before and after gear change
Level.
(8) driver is only the connection for carrying out clutch without gear change for example under accelerator on-state
In the case of, the precipitous variable gradient of engine rotary speed occurs, so even if carrying out gear change without actual, also has
It misjudged may be set to and carry out gear change.But gear change is carried out as long as no actual, just not before and after gear change
The change of the engine rotary speed of the change based on gear ratio occurs.On this point, due to having made before gear change
Velocity variable afterwards less than setting in the case of the result of determination that makes to be set to gear change be invalid structure, so energy
Enough suppress the misinterpretation of gear change.
(9) engine rotary speed and engine load can be used to judge the neutral gear of variable-speed motor 17, is being determined as neutral gear
In the case of, the speed change level of gear can be reset.
(10) after being determined as that variable-speed motor 17 is neutral gear, in the variable quantity corresponding to engine load, engine rotation is fast
In the case that the variable quantity of degree is less than regulation variable quantity, it can determine that and be switched to 1 speed for gear.
(11) during the shielding for not judging the presence or absence of gear change after gear change is carried out, is set, so can
Avoid in the presence or absence of next misjudged fixed tooth round transformation of gear change.
(12) it is one to be set to condition with engine load, the presence or absence of gear change is judged, so can be revolved using engine
The variable quantity of rotary speed correctly judges the presence or absence of gear change.
