Bright, first, from the expansion stroke of the cylinder performing fuel cut-off, engine rotation movement
(401) while slowing down (403), the compression TDC (404) of initial cylinder is arrived.More
When crossing this compression TDC (404), the repulsive force (repulsion) of the air because filling in combustor,
The most first to direction change (405) accelerated.Afterwards, because the work done during compression of next cylinder increases, send out
The friction of motivation increases, the repulsive force of the air filled in engine friction is more than combustor this
A bit (in figure 406) rise, and engine rotation movement carries out slow down (407), until next gas

Number of cylinders (being the phase contrast between cylinder strictly speaking) according to electromotor and the valve opening of air bleeding valve
In the moment etc., there is different character.
On this basis, above-mentioned engine rotation movement recording equipment as this acceleration (405,
410) and deceleration (403,407) change point each crankangle (404,406,408,
409) place, records acceleration (405,410) respectively and deceleration (403,407) is (actual
The information of record illustrates in the embodiment using Fig. 5).
If being explained with control flow, then become embodiment as shown in Figure 5.Fig. 5
It is control during acceleration (405,410) or deceleration (403,407) of record certain point
Flow process.First, in S501, it is determined whether be in the first regulation crankangle.This is the most suitable
In whether reaching 404 in Fig. 4.When condition is false, advancing to S504, condition is set up
Time, in S502, record the engine speed in this moment.Afterwards, advance to S503, start
The increment of timer conter (timer counter).In S504, it is determined whether reach
Two regulation crankangles, are for example to determine whether to reach 406 in Fig. 4.Condition is false
Time, return S501, when condition is set up, advance to S505, record the engine speed in this moment,
In S506, make the timer conter of increment in S503 stop, recording this time counter value
(i.e. recording the time needed for 404 to 406).Thus, record about acceleration (in Fig. 4
405) the information of acceleration (slope).This flow process leaves it at that, but it practice, same
Record from deceleration (407) in the of 406 in Fig. 4.Execution control from S501 i.e., again,
Making the first crankangle in S501 is in Fig. 4 406, and second crankangle of S504 is replaced into figure
In 4 408, the period till engine stop, repeatedly this flow process, record each information.
Additionally, using the embodiment of above-mentioned first regulation crankangle and the second crankangle is to realize this
One method of invention, certainly can be to this interval, (the compression TDC (404) of this cylinder be extremely
Between the compression TDC of next cylinder (408)) acceleration and the base that segments further of deceleration
Record these information (the detailed slope between crankangle) on plinth, improve the rotation being explained later pre-
The precision surveyed.
Then S306 in Fig. 3 is described in detail.
First, Fig. 6 and Fig. 7 is based on the engine rotation movement of record in S304 in Fig. 3
Information, carries out engine rotation prediction in the future, needed for reaching above-mentioned goal mesh rotating speed
The sequential chart of the engine rotation prediction means that the time is predicted.Utilize this figure according to reality
Forecasting sequence mode illustrates.
Current time in this figure is T603, and in the figure of T603, left side represents that right side represents in the past
In the future.The solid line of 601 represents engine rotation movement in the past, the circle that the solid line of 601 is recorded
Each engine speed shown on shape labelling (604,605,606,607,608) and crank
Record in the time between angle S304 step in Fig. 3.The dotted line of 602 is intended to based in Fig. 3
The rotation movement that in S304, the information of the engine rotation movement of record is predicted.Make T603
In the case of S305 in Fig. 3, first, it is accelerated the prediction of movement, and the base of this control
This viewpoint is, based on acceleration alpha n (612) shown in figure and last acceleration alpha n-1
And acceleration alpha n-2 (610) of last time exists fixing dependency relation this point (611).
As it has been described above, arrive crankangle when accelerating upper change point (605,607,609) according to electromotor
Specification has different features, but if same electromotor, then arrive accelerate upper change point (605,
607,609) crankangle time, in the case of its cylinder difference, is also roughly the same song
Handle angle.Therefore, only it is to be understood that accelerate engine speed and the past in starting point (608) moment
Acceleration (610,611), it becomes possible to according to linear function etc., easily predict adding of this cylinder
Speed upper change point (609) engine speed and from accelerate starting point (608) arrive accelerate the upper limit
Time needed for point (609).Additionally, acceleration alpha n of this prediction (612) can be according to upper
Acceleration alpha n-1 (611) and acceleration alpha n-2 of last time (610) once use secondary letter
Numbers etc., obtain with a certain degree of accuracy computation, but the district reduced in engine speed especially
In territory, because there is the change of filling rate, sometimes acceleration (610,611,612) is caused
Impact, it is advantageous to be modified it.Additionally, according to causing engine friction (engine
The operating state of subsidiary engine class (alternating current generator etc.) friction) and brake pressure etc. are repaiied
Just, precision of prediction can the most certainly be improved further.
Fig. 6 thus predicts the situation till the acceleration upper change point (609) of this cylinder, profit
With Fig. 7, the Forecasting Methodology of ensuing decelerating area is illustrated.The reality of 701 in Fig. 7
Line represents the engine rotation movement during inertial rotation because of fuel cut-off, and the dotted line of 702 is intended to base
The rotation movement that in S304, the engine rotation movement of record is predicted in Fig. 3.
Additionally, the circular labelling (704,705,706,707) recorded on the solid line of 701 represents
Record regulation crankangle during above-mentioned engine rotation movement, on this circle labelling (704,705,
Between each engine speed and crankangle shown in 706,707) (between 704-705,705-706
Between, between 706-707) time S304 step in Fig. 3 in record.Additionally, order
Current point on time shaft is T703, and in thus lighting figure, left side represents in the past, right side represent by
Come.
The engine speed of deceleration starting point (708) and the time to this point, according to combination
The explanation of Fig. 6 is the most predicted, so as the prediction of acceleration, only it is to be understood that in the past
Deceleration (712,713), it becomes possible to the next deceleration lower-limit point (709) of easily prediction
Engine speed and needed for deceleration starting point (708) arrives deceleration lower-limit point (709) time
Between.The prediction of this acceleration and deceleration is repeated, it was predicted that in the acceleration that next cylinder is later
Point of accumulation 710, will finally predict that the engine speed obtained becomes setting (such as less than 0rpm
Situation etc.) moment (figure in 711) be predicted as engine stop-state.
Then, based on the engine rotation movement that obtains of prediction, calculating becomes above-mentioned target and nibbles
Close the moment T717 of rotating speed (716), it was predicted that needed for current moment T703 to T717
Time (718), and because having predicted the final deceleration β n+1 (715) in Fig. 7
With the engine speed of starting point (710) Yu terminal (711), it is possible to ask with linear function
The time gone out to 716.Wherein, this prediction is not only to carry out once, but many arranging
On the basis of individual prediction time, through the stipulated time from above-mentioned prediction, become next pre-
Survey the moment (such as T719 in figure), the up-to-date electromotor movement information obtained based on this moment,
Same prediction is repeated.
Fig. 8 is above-mentioned engine rotation prediction means (details of the S306 step in Fig. 3)
Flow chart.First, in S801, it is predicted the initialization of cylinder enumerator n.Afterwards,
Being made whether the judgement that degree of being accelerated is predicted in S802, this judgement is according to during prediction time
Crankangle, the enforcement being accelerated prediction and prediction of slowing down judges.Such as, when current when
It is in Fig. 6 in the case of T603, is first accelerated prediction, carrying out prediction of slowing down afterwards.Bar
When part is false, advance to S806, when condition is set up, advance to S803.In S803,

(T904) make little gear (101e, 201e) and the ring gear (106,206) predicted are nibbled
In the moment closed, 906 is the time needed for current time to engagement.
Herein, in little gear rotates movement (802), the motor that stops (101a, 201a)
Energising after deceleration (802b), depend on starter specification and (particularly start motor
The inertia force of (101a, 201a)), stop the logical of motor (101a, 201a) just
After electricity, it may occur that crossing of little gear rotational speed (902) rushes (overshoot) etc., so becoming
Need to wait that a certain degree of time passes through before stable deceleration (902b).Herein, will
This time is designated as 913, if waiting this time process conversely speaking, then can ensure little gear
The deceleration (802b) rotating movement is fixing slope.
Thereby, it is possible to obtain T910, and then according to above-mentioned goal mesh rotating speed (907) and little tooth
Wheel deceleration (902b), utilizes linear function, it is also possible to obtain the little gear rotational speed of target (908).
As long as having obtained the little gear rotational speed of target (908), additionally it is possible to according to start motor (101a,
Response (in other words, the acceleration of 902a) 201a) easily obtain starting motor (101a,
Energising start time (T909) 201a).Supplementary notes, then start motor (101a, 201a)
Acceleration 902a depend on to start motor (101a, 201a) energising time electric current, institute
With if the structure of Fig. 2, then can be according to each driving duty starting motor energising
Ratio, presets the time (911) reached needed for the little gear rotational speed of target (908).Additionally,
If the structure of Fig. 1, then it is constant for driving electric current, it is possible to by any (one
Individual) constant setting this required time of performance (911).
Then the release moment of little gear (101e, 201e) is illustrated, be then actually
Little gear (101e, 201e) is made to engage to ring gear (106,206), to magnetic
Switch (101b, 201b) has been initially powered up until actual being engaged needs the stipulated time
(914).Required time (914) depends on magnetic switch (101b, 201b) herein
The electric current flow through in resistance and magnetic switch (101b, 201b), so by grasping these,
The response time (914) of magnetic switch (101b, 201b) also is able to be previously set.
Further supplementary notes, the then resistance of magnetic switch (101b, 201b) and magnetic switch
The temperature of (101b, 201b) has dependency, flows through in magnetic switch (101b, 201b)
Electric current can be with the electricity in the driving stage driving dutycycle or magnetic switch (101b, 201b)
Resistance replaces.Thereby, it is possible to obtain 914, so also being able to calculate the release moment of little gear
(T911)。
When this flow process control flow chart is represented, as shown in Figure 10.Figure 10 is S307 in Fig. 3
Detail flowchart.First, in S1001, deduct from the moment of above-mentioned goal mesh rotating speed
According to the magnetic switch (101b, 201b) being used for making little gear (101e, 201e) action
Required time (913) depending on response, thus the entering of computing little gear (101e, 201e)
Enter the moment.Then, in S1002, deduct until little from the moment of above-mentioned goal mesh rotating speed
Gear deceleration (902b) becomes the constant required time (912), and thus computing starts motor
The energising stop timing (T909) of (101a, 201a).In S1003, according to above-mentioned target
Engagement rotating speed, primary reduction gear speed (902b) and until primary reduction gear speed (902b) change perseverance
The fixed required time (912), the little gear rotational speed of computing target (907).Afterwards, at S1004
In, according to the little gear rotational speed of the target obtained in S1003 (907) with according to electronic to starting
The response time that the electrical current etc. of machine (101a, 201a) is obtained, obtain starting motor (101a,
Energising start time 201a).
Then, control to illustrate to the starter of S308 in Fig. 3.
