Specific embodiment
Hereinafter, the embodiments of the present invention will be described with reference 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, for by the manual operation of driver by the speed change grade of variable-speed motor
It is fast to the structure switched between 5 speed in neutral gear and 1.
[embodiment 1]
In vehicle 10 shown in Fig. 1, engine 11 is the driven internal combustion engine of burning by fuel, such as it is known that
Sample suitably has fuel injection valve and igniter etc..
On engine output shaft 12, variable-speed motor 17 is connected to via the clutch apparatus 16 as power transfer mechanism.
Clutch apparatus 16 is slip clutch, has one group of clutch mechanism, and the clutch mechanism is defeated with engine is connected to
The plectane (flywheel etc.) of 11 side of engine on shaft 12 and the plectane for 17 side of variable-speed motor being connected on variable-speed motor input shaft 21
(clutch disk etc.).By in clutch apparatus 16 two plectanes contact with each other, become between engine 11 and variable-speed motor 17
The power delivery status (clutch connection status) for transmitting power, is left each other by two plectanes, becomes engine 11 and speed change
The power off state (clutch dissengaged positions) that power transmitting between machine 17 is cut off.Alternatively, it is also possible to being in variable-speed motor
The structure of 17 inside setting clutch apparatus 16.
Variable-speed motor 17 is the hand gear machine with multiple speed change grades.Variable-speed motor 17 will be inputted from variable-speed motor input shaft 21
The power of engine 11 by by driver manual operation switching speed change grade gear ratio come speed change, to variable-speed motor output shaft
22 outputs.Speed change grade is in the state that driver operates clutch lever (diagram is omited) on the handlebar for being located at vehicle, by gear
Pedal switches over operation.Rear-wheel (wheel 27) is connected on variable-speed motor output shaft 22.
In addition, in the present system, having the Engine ECU (hereinafter referred to as ECU30) of the operating status of control engine 11
As vehicle-mounted control mechanism.ECU30 is the known electronic control unit for having microcomputer etc., based on being located at this system
In the testing result of various sensors etc. be appropriately carried out the control of engine 11.
As sensor class, the accelerator opening sensor equipped with the detection accelerator opening being located on accelerator handle
41, 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 is equivalent to load sensor, can start from detection
Some of which is arranged in machine load this point.
Testing result of the ECU30 based on various sensors implements the combustion for controlling the amount of the fuel sprayed by fuel injection valve
The various engines control of the ignition control of igniting that the control of material the amount of injection and control are carried out by igniter etc..In addition, this reality
The ECU30 for applying mode stores the resume of engine rotary speed in storage unit (diagram is omited) with time series, according to the hair
The resume of motivation rotation speed judge the presence or absence of implementation of gear change and gear position.
Here, the determination method of the presence or absence of the gear change carried out by ECU30 is illustrated.Fig. 2 is to indicate that gear becomes
The explanatory diagram with the relationship of engine rotary speed is changed, when (a) indicates upshift, when (b) indicating 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, combination (combination of pitch wheel) the i.e. gear ratio of the gear of variable-speed motor 17
Switching, so the engine rotary speed before and after gear change significantly changes.In the present embodiment, based on along in this way
The dynamic testing result of engine rotary speed of gear change determine the presence or absence of gear change.
Specifically, ECU30 calculates engine rotary speed NE1 based on the detection information of rotation speed sensor 44, and
By the way that engine rotary speed NE1 to be passivated to (annealing, smooth, annealing) processing, passivation rotation 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 making the variation passivation of original value.Being passivated rotation speed NE2 for example can be by using defined deactivation constant a1
Passivation operation shown in formula below (1) is repeated with specified period to calculate in (< 1).
NE2=(1-a1) × NE2+a1 × NE1 ... (1)
That is, by the previous value to passivation rotation speed NE2 multiplied by the value after (1-a1) and to engine rotary speed NE1
This sub-value multiplied by after a1 value be added, by its result be set as passivation rotation speed NE2 this sub-value.It in addition to this, can also be with
It is made into structure of the filtering processing for implementing low-pass filtering etc. as Passivation Treatment, by will be at engine rotary speed NE1 filtering
Reason is passivated rotation speed NE2 to calculate.
Also, ECU30 subtracts engine rotary speed NE1 from passivation rotation speed NE2, calculates rotation variation Δ NEA
(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 becomes smaller value, i.e., the value near 0.In contrast, if
It upshifts, then the variation of gear ratio occurs, so the precipitous variation of engine rotary speed NE1 occurs in moment t1~t2
Gradient.In the case, in upshift, the state that engine rotary speed NE1 is rising, hair are connected from by accelerator
Raw the anxious of change bring engine rotary speed NE1 because of gear ratio declines, so rotation changes after gear change starts
Amount Δ NEA sharp increases.Here, it is more than defined threshold alpha by rotation variation Δ NEA, upshift can have been made only
Determine.
In addition, the gear change judgement based on rotation variation Δ NEA compared with threshold alpha also can be used in by from speed change
The neutral state that the gear of machine 17 is not engaged is switched to the judgement when engaged gears state of engaged gears.
In addition, being engaged gears state before moment t3, under the engaged gears state, being not susceptible to send out in Fig. 2 (b)
The rotation of the motivation rotation status sudden turn of events changes, and rotation variation Δ NEA becomes smaller value, i.e., the value near 0.Relative to
The variation of gear ratio occurs if downshifted in this, so the steep of engine rotary speed NE1 occurs in moment t3~t4
High and steep variable gradient.In the case, in downshift, declining from engine rotary speed NE1 is disconnected by accelerator
State, the anxious rising by the change bring engine rotary speed NE1 of gear ratio occurs, so starting in gear change
Afterwards, rotation variation Δ NEA is sharp reduced.Here, defined threshold value beta is lower than by rotation variation Δ NEA, can made
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
More easily rise, so passivation rotation speed NE2 easily becomes smaller value in terms of engine rotary speed NE1.That is, rotation
Variation Δ NEA is easy to become biggish value to negative side.Therefore, it is possible to unexpectedly occur along with the tooth for becoming Δ NEA < β
The misinterpretation of round transformation.
So in the present embodiment, in the case where being neutral state, by with phase the case where being engaged gears state
Than making the degree of passivation for being passivated operation become smaller, the misinterpretation for realizing gear change is prevented.Specifically, in engaged gears state
Under, deactivation constant a1 is used in the passivation operation of above-mentioned formula (1), under neutral state, using blunt compared with deactivation constant a1
The small deactivation constant a2 of change degree.It here, is a1 < a2 < 1.It is illustrated by Fig. 3.
In Fig. 3, NE2 (a1) is to be indicated using the calculated passivation rotation speed of deactivation constant a1 with single dotted broken line.This
Outside, NE2 (a2) is to be indicated using the calculated passivation rotation speed of deactivation constant a2 with thick dashed line.Variation Δ NEA is rotated,
It is corresponding with NE2 (a1) to be indicated with single dotted broken line, it is corresponding with NE2 (a2) to be indicated with thick dashed line.
In Fig. 3, due to having used the passivation rotation speed NE2 (a1) of deactivation constant a1 relative to engine rotary speed
The rising of NE1 and more gently rise, it is possible to as illustrated before gear change become Δ NEA < β.Relative to
This becomes according to the passivation rotation speed NE2 (a2) for having used deactivation constant a2 even if same engine rotary speed NE1 rises
Change and also inhibits to become Δ NEA < β.
In addition, engine rotary speed NE1 is due to gear change and other than changing, it is also possible to according to its of interference etc.
His factor and change.For example, driver is singly to carry out breaking for clutch without gear change under accelerator on-state
In the case where opening/connecting, since the precipitous variable gradient of engine rotary speed NE1 occurs, so even if it is unpractical into
Row gear change, it is also possible to it is misjudged be set to carried out gear change.But if not practical carry out gear change, just not
The variation of the engine rotary speed NE1 of the change based on gear ratio occurs before and after clutch cutting.
In the present embodiment, it in the case where being judged to having carried out gear change based on rotation variation Δ NEA, calculates
The difference of engine rotary speed NE1 before and after gear change is changed as rotation speed variation delta NEB based on the rotation speed
Δ NEB is measured, determines the judgement of gear change the result is that effectively or invalid.Specifically, rotation speed variation delta NEB passes through
Engine rotary speed NE1 before clutch cutting (that is, when clutch is connected) is subtracted after clutch is cut off (that is, clutch
When disconnection) engine rotary speed NE1 calculate.
If be illustrated using Fig. 4, with gear change and feelings that engine rotary speed NE1 is changed
(referring to the A of Fig. 4) under condition, the rotation speed variation delta NEB of the clutch cutting front and back of the change based on gear ratio is calculated.Separately
On the one hand, (referring to Fig. 4 in the case that variation has occurred in engine rotary speed NE1 in the state of no progress gear change
B), clutch cutting front and back rotation speed variation delta NEB essentially become 0.
In the present embodiment, it in the case where the absolute value of rotation speed variation delta NEB is less than specified value γ, is based on
Variation Δ NEA is rotated, the judgement result for having gear change is set as invalid.In the example in fig. 4, in the case where A, gear
The judgement result of transformation is effective, in contrast, the judgement result of gear change is invalid in the case where B.In addition, it is specified that
Value γ can be preset based on experiment etc..
Then, the gear change determination processing that ECU30 is executed is illustrated using the flow chart of Fig. 5 and Fig. 6.In addition,
Reason is implemented in the state that the ignition switch that the illustration is omitted is switched on specified period repeatedly everywhere in below.
In this process, determine whether previous gear position is neutral gear (S11) first.Present treatment is in previous processing
It is determined as affirmative when gear position is neutral gear.In addition, the details that neutral gear determines is illustrated in S18.
Be determined as in S11 it is previous calculate passivation rotation speed NE2 using deactivation constant a2 in the case where be neutral gear, and
And engine rotary speed NE1 is subtracted from passivation rotation speed NE2, calculate rotation variation Δ NEA (S12).It is determined that
Whether calculated rotation variation Δ NEA is threshold alpha or more (S13) in S12.In the case where S13 is negative, it is determined as
Neutral state is maintained (S14).
S13 be affirmative in the case where, i.e., in the case where Δ NEA≤α, determine gear change condition for validity whether at
Vertical (S15).In present treatment, calculate be judged as Δ NEA≤α front and back (that is, will become Δ NEA≤α it is tight before and once at
Be next as Δ NEA < α again after Δ NEA≤α) rotation speed variation delta NEB, and change in the rotation speed
In the case that the absolute value of amount Δ NEB is specified value γ or more, it is effective for being set as gear change judgement.In the feelings that S15 is affirmative
Under condition, it is judged to being switched from neutral gear for 1 fast (S16).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 using under engaged gears state
Big value (in other words, the lesser value of degree of passivation), so that not becoming rotation variation Δ NEA < threshold value beta under neutral gear.
In the case where S11 is negative, i.e., it is some of 1 fast~5 speed in previous gear position and is engaged gears shape
In the case where state, carry out neutral gear judgement (S17).Here, about being neutral state, based on engine rotary speed NE1 and start
Machine load is determined.
Neutral gear determination processing is indicated in Fig. 6.First, it is determined that whether engine rotary speed NE1 is idling rotation speed
(S31).By S31 certainly, determine whether to become the fully closed state (S32) of air door.In present treatment, it is being 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 where, be judged to becoming the fully closed state of air door.The case where S32 is certainly
Under, determine whether to have passed through stipulated time (S33) certainly from S32.Also, in the case where S33 is affirmative, judgement is empty
Shelves (S34).In the case where in some of S31~S33 to negate, it is determined as not being neutral gear but engaged gears state (S35).
, can also be when some of S31 and S32 conditions continue for the stipulated time other than above-mentioned, judgement is neutral gear.This
Outside, the fully closed state of air door can also be determined to be based on accelerator disconnection is become in S32.In addition it is also possible to based on pair
Should in engine load (testing result etc. of air-breathing pressure sensor 43) variation and engine rotary speed NE1 excessively rises to
More than fixing speed, it is judged to 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 where neutral gear, gear position is reset into (S26).
In the case where being determined as is not neutral gear but 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 rotation speed NE2 and engine rotary speed NE1.So
Afterwards, determine whether rotation variation Δ NEA is threshold alpha or more (S20).In the case where S20 is affirmative, gear change is determined
Whether condition for validity is true (S21).It is same as the processing of S15 in present treatment, the rotation before and after being judged as Δ NEA≤α
In the case that the absolute value of rotary speed variation delta NEB is specified value γ or more, it is believed that gear change judgement is effective.?
In the case that S21 is affirmative, it is judged to being upshift (S22).In the case, such as to previous gear position add 1 grade, be set as
Current gear position.
In the case where S20 is negative, Δ NEA < β (S23) is determined whether.In the case where S23 is affirmative, tooth is determined
Whether the condition for validity of round transformation is true (S24).In present treatment, (that is, to become Δ before and after being judged as Δ NEA < β
Before NEA < β is tight and once becoming that become Δ NEA≤β again after Δ NEA < β next) rotation speed variation delta NEB it is absolute
In the case that value is specified value γ or more, it is believed that gear change judgement is effective.In the case where S24 is affirmative, judgement is
It downshifts (S25).In the case, such as by previous gear position subtract 1 grade, be set as current gear position.In addition, S21,
In the case that S23, S24 are negative, it is believed that keep the previous value of gear position without gear change.
[embodiment 2]
It in above embodiment 1, has been made into such as flowering structure: based on as engine rotary speed NE1 and passivation rotation
The rotation variation Δ NEA of the difference of rotary speed NE2 is judged to having occurred the precipitous variable gradient of engine rotary speed NE1
In the case of, determine carried out gear change.In contrast, in the present embodiment, based on being sent out in engine rotary speed NE1
It has given birth to the variable gradient of regulation gradient or more and the increase and decrease of the engine rotary speed NE1 in specified time limit then has occurred
Repeatedly, determine the presence or absence of gear change.
In addition, calculating the engine rotary speed before and after gear change in the case where being judged to having carried out gear change
The difference of NE1 is based on rotation speed variation delta NEB as rotation speed variation delta NEB, determines the speed change grade of variable-speed motor 17
It has risen or has dropped.
The detailed variation of engine rotary speed NE1 when illustrating upshift operation using Fig. 7.Upshift when, by by
Driver is by clutch rupturing operation (opening operation), and engine rotary speed NE1 suddenly rises 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, the increase and decrease of engine rotary speed NE1 occurs as P3 repeatedly.
Here, the sudden turn of events of the engine rotary speed NE1 at P1 and P2 can be based on the differential of engine rotary speed NE1
Value becomes specified value or more to determine.It in addition to this, can also be based on engine rotary speed NE1 and passivation rotation speed NE2
Difference determine the sudden turn of events of engine rotary speed NE1.The sudden turn of events for determining the engine rotary speed NE1 at P2, is equivalent to and sentences
It is scheduled on the variable gradient that regulation gradient or more has occurred in engine rotary speed NE1.
In addition, diagram is omitted, but the state due to disconnecting in downshift as accelerator, so even if clutch disconnects,
Also it is not susceptible to the sudden turn of events of the engine rotary speed NE1 disconnected along with the clutch.But with after downshift operation from
Clutch connection, engine rotary speed NE1 suddenly rise, also, engine rotation then occurs by carrying out half-clutch device operation
The increase and decrease of speed NE1 is repeatedly.
Fig. 8 is the flow chart for indicating gear change determination processing, and present treatment is replaced by the processing of above-mentioned Fig. 5, by ECU30
Implement.
In fig. 8, neutral gear judgement (S41) is carried out first, (is yes in S42 in the case where being determined as is neutral state
In the case of), gear position is reset into (S43).The processing of the S41~S43 is processing identical with S17, S18, S26 of Fig. 5.
In addition, in the case where being determined as is not neutral gear but engaged gears state (in the case that S42 is no), implement from
The processing (S44) that clutch operation determines.Clutch operating judgement is based on the engine rotary speed NE1 being illustrated in Figure 7
Variation dynamic come what is carried out, its order is indicated in Fig. 9.When namely based on engine rotary speed NE1 to upshift or when downshifting
The variation of defined variation patterns, determine the presence or absence of clutch operating.
In Fig. 9, determine whether to have carried out clutch disconnection, i.e., the engine disconnected along with clutch whether has occurred
The sudden turn of events (S51) of rotation speed NE1.In addition, the sudden turn of events (anxious to rise) of the NE1 disconnected along with clutch is when upshifing
, only it can implement S51 in upshift.In addition it is also possible to which S51 is omitted.In the case where S51 is affirmative, determine whether to send out
It has given birth to and has increased along with the urgency of the engine rotary speed NE1 of the attended operation of clutch 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 have occurred by
Carry out the increase and decrease (S53) of half-clutch device operation bring engine rotary speed NE1.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 be 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 judgement as a result, determining whether that gear change has occurred
(S45).Also, in the case where being determined as has gear change, calculate the engine rotary speed NE1's before and after gear change
Difference, as rotation speed variation delta NEB (S46).At this point, from the NE1 before gear change subtract gear change after NE1, meter
Calculate rotation speed variation delta NEB.
Then, it is determined that whether being positive value (S47) for rotation speed variation delta NEB.In the case where S47 is affirmative, sentence
Being set to is upshift (S48).In the case, such as to previous gear position 1 grade is added, is set as current gear position.This
Outside, in the case where S47 is negative, it is judged to being downshift (S49).In the case, such as by previous gear position 1 is subtracted
Grade, is set as current gear position.In addition, in the case where S45 is negative, it is believed that there is no gear change, keep gear position
Previous value.
In addition, in the processing of Fig. 8, it can also be same as Fig. 5, it is made into and determines whether the condition for validity of gear change is true
Structure.In the case, same as the processing of the S15 of Fig. 5 such as after S46, it is put into the rotation determined before and after gear change
The absolute value of velocity variable Δ NEB whether be specified value γ or more processing.And it is possible to be set as | Δ NEB |≤γ's
In the case of gear change judgement be effectively, in | Δ NEB | gear change judgement is invalid in the case where < γ.
[other embodiments]
More than, embodiments of the present invention 1 and 2 are illustrated, but purport of the invention can also not departed from
Implemented in range with various forms.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 defined conditions to gear position it is related.For example, under conditions of speed is certain, gear
Position (series) is smaller, and rotation speed variation delta NEB is bigger.So also can use such gear position and rotation speed
The correlativity of variation delta NEB is spent to determine gear position.
The relationship of the variation of engine rotary speed NE1 and the variation of gear position (speed change grade) is indicated in Figure 10.Figure
10 indicate the variation of engine rotary speed NE1 of the speed change grade with 1 speed → 2 speed → 3 speed → 4 speed → 5 speed variation when.
In Figure 10, the rotation speed variation delta NEB before and after gear change is in speed change grade to be when 1 speed → 2 speed variation
Δ N1, speed change grade with 2 speed → 3 speed variation when be Δ N2, speed change grade with 3 speed → 4 speed variation when be Δ N3, speed change grade with
It is Δ N4 when 4 speed → 5 speed variation.In the case, Δ N1~Δ N4 is positive value, is based on this, is judged to being upshiftd.Separately
Outside, diagram is omitted, but Δ NEB is negative value in the case where downshift, is judged to being downshifted based on this.
Δ N1~Δ N4 corresponds respectively to the variation of gear ratio and is different values, e.g. Δ N1 > Δ N2 > Δ N3 > Δ
N4.In the case, rotation speed variation delta NEB changes according to the series of variable-speed motor 17, before depending on gear change
The variation of the gear when gear ratio after gear change, the speed change grade i.e. before and after gear change.So by before and after gear change
The variation of speed change grade and the relationship of the rotation speed variation delta NEB before and after same gear change are redefined for relation data,
Using the relation data, the speed change grade after gear change is determined based on each rotation speed variation delta NEB.
For example, in the case where being judged to having gear change, being upshiftd or downshifted, making in above-mentioned Fig. 5 or Fig. 8
With above-mentioned relation data, gear position is determined based on each rotation speed variation delta NEB.

Certainly.In the case where S61 is affirmative, the variable quantity (S62) of engine rotary speed NE1 is calculated.For example, calculating the micro- of NE1
Variable quantity of the score value as engine rotary speed NE1.Then, based on calculated engine rotary speed NE1's in s 62
Variable quantity, determines whether engine rotary speed NE1 excessively rises fixing speed or more (S63).At this point, can also be according to wind
The variable quantity of door aperture, is variably set the excessive rising decision content of NE1.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 are negative, it is determined as not being neutral gear but gear is stung
Conjunction state (S65).
It (6) can also be that centainly (variable quantity is not with engine load (such as pressure of inspiration(Pi)) in above-mentioned Fig. 5, Fig. 8, Fig. 9
To regulation variable quantity) it is condition, determine the presence or absence of gear change.That is, if being conceived to the speed before and after gear change and starting
Machine load does not change, then engine rotary speed when identical load (pressure of inspiration(Pi)) occurs is different.It therefore, can be 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 can suitably carry out the supposition of gear position in speed and the identical region of pressure of inspiration(Pi).
(7) can also be judged to being downshift in Air suction pipe pressure when being declined to become specified value or more.
(8) among the above, can not also determine the series of gear, and determine 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

(10) become invalid in the determination processing that downshift among the above, can also be made in neutral gear.For example, in above-mentioned Fig. 2,
Without using the judgement of the threshold value beta of downshift side.In the case, it also can be avoided the mistake of the gear change (downshift) under neutral gear
Determine.
(11) among the above, adding for the operating quantity (accelerator opening) of detection accelerator handle is equipped in automatic two-wheeled cycle
In the case where fast device sensor, the testing result of the accelerator opening obtained by accelerator sensor can be used also to determine tooth
Take turns position.For example, it is also possible to the degree of the rising of engine rotary speed NE1 corresponding with accelerator opening be added, to determine
Gear position.
[function and effect]
According to above embodiment 1 and 2 and other embodiments, good effect below can be played.
(1) when carrying out the gear change of variable-speed motor 17, cause of occurrence is in the engine rotary speed of the variation of gear ratio
Precipitous variable gradient.In the case, gear change is determined based on the precipitous variable gradient of engine rotary speed
The presence or absence of, to even if can also determine tooth in simple structure without using gear position sensor or wheel speed sensor etc.
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 of rotary speed becomes larger.In particular, when upshifing in the acceleration of vehicle 10, the rotation speed along with upshift occurs
Anxious decline.In addition, occurring to rise along with the anxious of rotation speed of downshift when downshifting in the deceleration of vehicle 10.In this way
In the case where, since the passivation rotation speed NE2 of engine rotary speed prolongs relative to detected value (engine rotary speed NE1)
Change late, so engine rotary speed NE1 and the speed difference Δ NE of passivation rotation speed NE2 temporarily suddenly increase.Pass through benefit
With the feature, the presence or absence of gear change can be suitably determined.
(3) under neutral state, compared with engaged gears state, when accelerator is connected, engine rotary speed is easy anxious
Rise, the misinterpretation of gear change is easy to happen due to the precipitous variable gradient of generation.About this point, due to being tied to be following
Structure keeps degree of passivation small to calculate passivation rotation speed NE2, so can under neutral state, compared with engaged gears state
Realize that the misinterpretation of gear change prevents.
(4) it can be considered after the gear change of clutch when it is disconnected operates, in order to smoothly to clutch connection
State switches and carries out half-clutch device operation.In the case, the interior increase and decrease that engine rotary speed NE1 occurs during the prescribed period
Repeatedly.Thus, by the precipitous variable gradient and subsequent engine that are judged to having occurred engine rotary speed NE1
The increase and decrease of rotation speed NE1 repeatedly, can suitably determine the presence or absence of gear change.
(5) it under engaged gears state, compared with the neutral state that gear is not engaged, is connected in the accelerator of driver
When be not susceptible to the anxious of engine rotary speed and rise.Therefore, by being changed based on rotation to be engaged gears state as condition
It measures Δ NEA and determines the presence or absence of gear change, thus, it is possible to improve the judgement precision of gear change.
(6) when having carried out gear change, according to the variation of gear ratio, occur engine rotary speed to increase side or
Reduce the variation of side.Thus, according to the variable quantity of the engine rotary speed of the front and back of gear change, it can be determined that variable-speed motor
17 speed change grade rises or drops.
(7) variable quantity of the engine rotary speed before and after gear change corresponds to the series of variable-speed motor 17 and changes, according to
The variation of gear before being stored in the gear change when gear ratio after gear change, the speed change grade i.e. before and after gear change.Pass through
Using this point, the speed change of variable-speed motor 17 can be determined based on the size of the difference of the engine rotary speed before and after gear change
Grade.
(8) driver is only the connection for carrying out clutch without gear change for example under accelerator on-state
In the case where, the precipitous variable gradient of engine rotary speed occurs, so also having even if carrying out gear change without practical
It misjudged may be set to and carry out gear change.But gear change is carried out as long as no practical, just not before and after gear change
The variation of the engine rotary speed of the variation based on gear ratio occurs.About this point, due to being made into before gear change
Velocity variable afterwards less than specified value in the case where keep the judgement result for being set as gear change invalid structure, so energy
Enough inhibit the misinterpretation of gear change.
(9) it is able to use engine rotary speed and engine load determines the neutral gear of variable-speed motor 17, be determined as neutral gear
In the case where, the speed change grade 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 be determined that gear is switched to 1 speed.
(11) during the shielding for not determining the presence or absence of gear change after carrying out gear change, is arranged, so can
It avoids 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 determined, so being able to use engine rotation
