Patent document 1: Japanese Unexamined Patent Publication 2014-1684 bulletin
In recent years, there is a situation where such: even if vehicle does not stop, being automatically stopped internal combustion engine or automatic restarting.
More specifically, start being automatically stopped for internal combustion engine when speed is not 0, then, before the revolving speed of internal combustion engine becomes 0, lead to
The pedal of stepping on or step on the throttle that brake pedal is released by driver is crossed, thus producing the feelings such as automatic restarting request
Under condition, make the automatic restarting of internal combustion engine to respond the request immediately before the revolving speed of internal combustion engine becomes 0.
However, when making engine starting, what starter required is before and after the revolving speed of internal combustion engine becomes 0 across torque
Different.Here, refer to across torque, when being started by starter, in order to across first compression stroke, be transferred to
Expansion stroke and the torque for needing to pass to crankshaft.Since the pressure when piston reaches top dead centre in cylinder becomes maximum, because
This, piston reach top dead centre when in-cylinder pressure it is bigger, then across torque it is bigger.
Fig. 8 be show from issuing torque command to starter the stroke amount of piston until reaching top dead centre with for the first time

(revolving speed of internal combustion engine become 0 after automatic restarting) indicates that (internal combustion engine turns for automatic restarting in rotation with quadrangle mark
Speed become 0 before automatic restarting).As shown in figure 8, usually automatic restarting when first-time compression when top dead centre at cylinder
Interior pressure substantially proportionally prolongs growth with the stroke amount of piston.That is, also basic across torque when usual automatic restarting
The upper stroke amount with piston proportionally increases.This is because the gas flow being compressed by pistons also increases as stroke amount increases
Add.
In contrast, even if stroke amount is short, in the cylinder at top dead centre when first-time compression in rotation when automatic restarting
Pressure, i.e. in rotation when automatic restarting across torque also than usual automatic restarting when it is big.This is because in rotation certainly
In the case where dynamic restarting, the gas in cylinder is not escaped from valve or piston ring completely, and in-cylinder pressure is big.
As described above, in rotation when automatic restarting, across torque ratio usually automatic restarting when it is big.Therefore, when making
When with exporting small starter, there is starting internal combustion engine, there is a situation where postpone.

When fruit is "No", that is, when being that engine 1 is automatically stopped middle, inhaled air volume control unit 83 is transferred to S32.
In S32, inhaled air volume control unit 83 determines whether engine speed is greater than 0.When the judgement result of S32 is
When "Yes", that is, for just be automatically stopped engine 1 after and engine speed be not yet reduced to 0 in the case where, inhaled air volume
Control unit 83 operates air throttle 33, so that the aperture of air throttle 33 becomes target aperture in predetermined stopping (referring to S33),
Terminate the inhaled air volume control processing of Fig. 5.The sucking that target aperture is set so as to obtain as follows in the stopping is empty
The aperture of tolerance: the inhaled air volume make automatic restarting engine speed be greater than 0 in the state of engine 1 when hair
Motivation 1 crosses over torque (for the torsion for crossing over first compression stroke, being transferred to expansion stroke and being provided to crankshaft 17
Square) it is less than in the torque generated from starter-generator 52 under the electric power that power-supply system 6 supplies.Admission pressure is more reduced, more can
Reduce and cross over torque, therefore target aperture is set to substantially 0 degree for example as the fully closed aperture of air throttle 33 in the stopping.
When the judgement result of S32 is "No", that is, after a little time and sent out from being automatically stopped engine 1
In the case that motivation revolving speed is reduced to 0 later, inhaled air volume control unit 83 operates air throttle 33, so that the aperture of air throttle 33
1st target aperture (referring to S34) when as predetermined starting terminates the inhaled air volume control processing of Fig. 5.Here, it rises
1st target aperture is set to be greater than the aperture of target aperture in above-mentioned stopping, i.e. than target aperture in stopping by opening when dynamic
Side.In addition, the 1st target aperture is confirmed as when the starting: can obtain for the automatic restarting from engine speed is 0
The inhaled air volume of engine 1 and needs.
Therefore, it is handled according to the inhaled air volume control of Fig. 5, is being automatically stopped/restarting processing automatically from using Fig. 4
During being automatically stopped until engine 1 plays engine speed and becomes 0,33 absorbed air control unit 83 of air throttle dimension
It is substantially fully closed for holding.In addition, starting from being automatically stopped engine 1 using being automatically stopped of Fig. 4/automatic restarting processing
After machine revolving speed becomes 0, air throttle 33 maintains the 1st target aperture at the start by inhaled air volume control unit 83.
In addition, when the judgement result of S31 is "Yes", that is, when engine 1 is not to be automatically stopped middle, inhaled air volume
Control unit 83 is transferred to S41.In S41, inhaled air volume control unit 83 is determined whether to be switched from the value that I/S indicates from " 1 "
It is risen to " 0 " after have passed through the defined time.When the judgement result of S41 is "Yes", that is, from using being automatically stopped of Fig. 4/
Automatic restarting handle come automatic restarting engine 1 rise have passed through the defined time after in the case where, inhaled air volume control
Portion 83 processed is transferred to S42, executes usually controlling, be transferred to S45 for air throttle 33.In the usual control, inhaled air volume control
Portion 83 processed calculates to obtain to the output that engine 1 requires and in the inhaled air volume of the needs of engine 1 and in order to be somebody's turn to do
Inhaled air volume and the aperture of the air throttle 33 that needs, it is i.e. usual when target aperture, air throttle 33 is operated, so that air throttle 33
Target aperture when aperture is usual as this.In addition, inhaled air volume control unit 83 makes restarting mark in above-mentioned rotation in S45
The value of will is " 0 ", terminates the inhaled air volume control processing of Fig. 5.
In addition, when the judgement result of S41 is "No", that is, using being automatically stopped of Fig. 4/automatic restarting processing come
Not yet by the case where the defined time, inhaled air volume control unit 83 is transferred to S43 after automatic restarting engine 1,
Whether the value for determining restarting mark in rotation is " 1 ".When the judgement result of S43 is "Yes", that is, reduced in engine speed
In the case where the automatic restarting for starting engine 1 before to 0, inhaled air volume control unit 83 operates air throttle 33, so that section
2nd target aperture (referring to S44) when the aperture of valve 33 becomes predetermined starting terminates the inhaled air volume control of Fig. 5
Processing.Here, the aperture of the 1st target aperture when the 2nd target aperture is set to be greater than above-mentioned starting when starting, i.e. compared with it is dynamic when
1st target aperture leans on opening side.
In addition, when the judgement result of S43 is "No", that is, start engine 1 after engine speed is reduced to 0
In the case where automatic restarting, inhaled air volume control unit 83 is transferred to S34, air throttle 33 is operated, so that air throttle 33 is opened
1st target aperture when degree becomes above-mentioned starting terminates the inhaled air volume control processing of Fig. 5.
Therefore, it is handled according to the inhaled air volume control of Fig. 5, is automatically stopped/restarting processing automatically using Fig. 4 working as
In the case where after engine speed is reduced to 0 when starting the automatic restarting of engine 1, air throttle 33 is by inhaled air volume control
Portion 83 processed maintains the 1st target aperture at the start.In addition, starting to send out when using being automatically stopped of Fig. 4/automatic restarting processing
In the case that engine speed is not yet reduced to 0 when the automatic restarting of motivation 1, air throttle 33 is by inhaled air volume control unit 83
Maintain compared with it is dynamic when the 1st target aperture lean on opening side starting when the 2nd target aperture.
Fig. 6 is the timing diagram for showing the control example of ECU 8.Fig. 6 successively shows I/S mark since upper section, engine turns
Speed, the aperture of air throttle 33 and admission pressure.In addition, in fig. 6, it is illustrated that following situation: I/S mark value moment t0 from
" 0 " is switched to " 1 ", then, the value that I/S indicates is switched to " 0 " from " 1 " in moment t2.
Firstly, the value of I/S mark becomes in response to being determined as the case where automatic stop condition is set up from " 0 " in moment t0
More " 1 " (referring to the S2, S3 of Fig. 3).It is automatically stopped starting portion 82 as a result, and is determined as that being automatically stopped for engine 1 is requested
It generates, to stop the fuel injection control and ignition control of engine 1, starts being automatically stopped (referring to Fig. 4's for engine 1
S12, S13).Therefore, after the time t theta, engine speed gradually decreases.In addition, inhaled air volume control unit 83 in response to
Being automatically stopped request the case where having generated of moment t0 engine 1 and by the aperture of air throttle 33 be set as than it is usual when target open
Degree target aperture (being more specifically fully closed) in the stopping of close side (referring to the S32, S33 of Fig. 5).As a result, in moment t0
Later, admission pressure reduces.In addition, as shown in fig. 6, starting in moment t1 from being automatically stopped engine 1 in moment t0 and play
Machine revolving speed become 0 until during, inhaled air volume control unit 83 by the aperture of air throttle 33 maintain stopping in target aperture.
Then, in moment t1, inhaled air volume control unit 83 after moment t0 is automatically stopped engine 1 in response to starting
The case where machine revolving speed is reduced to 0 and by the aperture of air throttle 33 from stopping target aperture be changed to start when the 1st target aperture
(referring to the S32, S34 of Fig. 5).As a result, after the time tl, admission pressure is begun to ramp up.
Then, in moment t2, the value of I/S mark in response to be judged as the case where automatic restarting condition is set up and from
" 1 " is changed to " 0 " (referring to the S4, S5 of Fig. 3).It is automatically stopped starting portion 82 as a result, and is determined as that the automatic restarting of engine 1 is asked
It asks and has generated, to start the automatic restarting of engine 1 (referring to the S18, S19 of Fig. 4).More specifically, it is automatically stopped
Starting portion 82 carries out the Kick-start of engine 1 by supplying electric power from power-supply system 6 to starter-generator 52, passes through simultaneously
Fuel injection control and ignition control are carried out to start the automatic restarting of engine 1.In addition, in moment t2, air throttle 33
Aperture target when being maintained at the aperture needed to start engine 1, i.e. starting from engine speed is 0
Aperture.Therefore, after the time t 2, since the air of the amount needed to start engine 1 is supplied immediately to engine
1, therefore engine 1 can be started rapidly, engine speed is begun to ramp up.
In addition, I/S mark value after moment t2 is changed to " 0 " from " 1 ", in moment t3, inhaled air volume control unit
83 in response to have passed through the defined time the case where and start the usual control of air throttle 33 (referring to the S41, S42 of Fig. 5).
Fig. 7 is the timing diagram for showing the control example of ECU 8.Fig. 7 successively shows I/S mark since upper section, engine turns
Speed, the aperture of air throttle 33 and admission pressure.In addition, in FIG. 7, it is shown that following situation: the value of I/S mark is in moment t10
It is switched to " 1 " from " 0 ", then, the value that I/S indicates is switched to " 0 " from " 1 " in moment t11.That is, in figure 6 and figure 7, I/S
The value of mark is different from the timing that " 1 " is switched to " 0 ".
Firstly, in moment t10, the value of I/S mark is in response to being judged as the case where automatic stop condition is set up and from " 0 "
It is changed to " 1 " (referring to the S2, S3 of Fig. 3).It is automatically stopped starting portion 82 as a result, and is determined as that being automatically stopped for engine 1 is requested
Through generating, to be automatically stopped engine 1 (referring to the S12, S13 of Fig. 4).Therefore, after moment t10, engine speed by
Gradually reduce.In addition, inhaled air volume control unit 83 is in response to being automatically stopped what request had generated in moment t10 engine 1
Situation and by the aperture of air throttle 33 be set as than it is usual when target aperture by close side stopping in target aperture (more specifically
It is fully closed) (referring to the S32, S33 of Fig. 5).As a result, after moment t10, admission pressure is reduced.In addition, as shown in fig. 7, from
Engine 1 is automatically stopped in moment t10 to play before moment t11, engine speed became 0 until automatic restarting engine 1
During, the aperture of air throttle 33 is maintained target aperture in stopping by inhaled air volume control unit 83.
Then, in moment t11, the value of I/S mark in response to be judged as the case where automatic restarting condition is set up and from
" 1 " is changed to " 0 " (S4 of Fig. 3, S5).It is automatically stopped starting portion 82 as a result, and has been determined as the automatic restarting request of engine 1
Through generating, to start the automatic restarting of engine 1 (referring to the S18, S19 of Fig. 4).In addition, in the example in figure 7, automatically
T11 is generated at the time of restarting request is before engine speed is reduced to 0, and thus the value of restarting mark is set in rotation
For " 1 " (referring to the S20, S21 of Fig. 4).
In addition, as referring to as being illustrated Fig. 8, before engine speed becomes 0 after being automatically stopped engine 1
In the case where automatic restarting engine 1, it is greater than from engine speed is 0 required by starter-generator 52 across torque
Torque is crossed over required by starter-generator 52 when automatic starting engine 1.In contrast, in the present embodiment, from
Moment t10 is automatically stopped engine 1 and plays before moment t11, engine speed became 0 until automatic restarting engine 1
The aperture of air throttle 33 is maintained target aperture in stopping by period, and target aperture is confirmed as in the stopping: so that across
Torque is less than the torque that starter-generator 52 generates.In other words, from moment t10 be automatically stopped engine 1 play when
During carving t11 engine speed and becoming before 0 until automatic restarting engine 1, the control hair of inhaled air volume control unit 83
The inhaled air volume of motivation 1, so that being less than the torque that starter-generator 52 generates across torque when automatic restarting.Therefore,
In moment t11, even if being automatically stopped starting portion 82 can also start restarting automatically in the state that engine speed is greater than 0
Machine 1 is without postponing.
In addition, in moment t11, value quilt of the inhaled air volume control unit 83 in response to restarting mark in rotating as described above
The case where being set as " 1 " and by the aperture of air throttle 33 from stopping target aperture be changed to start when the 2nd target aperture, it is described
When starting the 2nd target aperture be confirmed as compared with it is dynamic when the 1st target aperture by opening side (referring to Fig. 5 S43, S44).As a result,
After moment t11, admission pressure is begun to ramp up.In addition, in order to refer to, being shown in broken lines will save in moment t11 in Fig. 7
It is obtained when the 1st target aperture when the aperture of valve 33 target aperture from stopping in the same manner as the example of Fig. 6 is changed to start
The variation of admission pressure.As shown in fig. 7, in the present embodiment, starting in restarting automatic before engine speed becomes 0
When machine 1, by by the aperture of air throttle 33 be changed to compared with it is dynamic when the 1st target aperture lean on opening side starting when the 2nd target open
Degree, thus can increase admission pressure immediately after the automatic restarting request of moment t11 engine 1 generates, therefore,
The air of required amount can be just rapidly provided in the engine 1 after automatic restarting, wherein the 1st target is opened when the starting
Degree is determined to be: can obtain the sucking air needed for the automatic restarting engine 1 from engine speed is 0
Amount.
In addition, the value indicated from I/S in moment t11 from " 1 " is changed to " 0 " ing, in moment t12, inhaled air volume is controlled
The case where portion 83 is in response to have passed through the defined time and the usual control for starting air throttle 33 (referring to the S41, S42 of Fig. 5).
More than, an embodiment of the invention is illustrated, still, the invention is not limited thereto.
For example, in the above-described embodiment, illustrate following situation: inhaled air volume control unit 83 passes through operation air throttle
33 control the inhaled air volume of engine 1, so that the engine 1 when automatic restarting is less than starter-generator across torque
The torque of generation.But the invention is not restricted to this.Other than using air throttle 33, inlet valve 15, exhaust valve can also be used
16, air inlet side changeable air valve timing lift mechanisms 18i and exhaust side variable valve timing lift mechanisms 19e controls engine
1 inhaled air volume.Inhaled air volume control unit can also be by operating these inlet valves 15, exhaust valve 16, air inlet side as a result,
Changeable air valve timing lift mechanisms 18i and exhaust side variable valve timing lift mechanisms 19e is empty come the sucking for controlling engine 1
Tolerance, so that the torque for being less than starter-generator generation across torque of the engine 1 when automatic restarting.
In addition, for example, in the above-described embodiment, illustrating following situation: starting before engine speed is reduced to 0
Inhaled air volume control unit 83 operates air throttle 33 in the case where the automatic restarting of engine 1, so that the aperture of air throttle 33
2nd target aperture when as predetermined starting.But the method for operating air throttle 33 is without being limited thereto.As shown in fig. 7,
When restarting, by opening air throttle 33 from closed state, increase (referring to Fig. 7 at the time of t11) admission pressure.Therefore,
When starting the automatic restarting of engine 1 before engine speed is reduced to 0, inhaled air volume control unit 83 can also pass through
The feedback control of air inlet pressure sensor 43 has been used to operate air throttle 33.That is, starting before engine speed is reduced to 0
When the automatic restarting of engine 1, inhaled air volume control unit 83 can also be by using the anti-of air inlet pressure sensor 43
Feedback control to operate air throttle 33 so that when the admission pressure detected by air inlet pressure sensor 43 becomes restarting target into
Atmospheric pressure, when the restarting target inlet air pressure be confirmed as: greater than automatic restarting before (be in the example in figure 7 the moment
T11 it is tight before) admission pressure and in order to from engine speed be 0 start engine 1 and need admission pressure.
