Description
Technical field
The present invention relates to motor vehicles and more particularly to a kind of engine stop for improving motor vehicles/starting systems
The method of the performance of system.
Background technique
Vehicle equipped with stop/start system and manual transmission is using the threshold value based on clutch pedal position come really
Determine when clutch pedal is discharged into releasing position from position is jammed on by driver.It is this to turn from the state that jams on to release conditions
Change be stopped/activation system be applied to stop engine.In addition, when driver moves by threshold value to position is jammed on from releasing position
When dynamic clutch pedal, this is stopped/and activation system is used as the trigger event for restarting engine.
Before this, these threshold values are fixed and set its numerical value to adapt to that foot is habitually stayed in clutch pedal
On driver (on April 5th, 2011 submit application No. is the same our British patents file of UK1206179.2 is detailed
Carefully describe this system and method).It is beneficial to by the method that the British patent file that this application number is UK1206179.2 proposes
Increase the validity of the stopping of all vehicles assembled in this way of entire fleet, and therefore improves overall fuel-economizing.Actual user
Data are analysis shows up to 35% user stays in its foot on clutch pedal.
However, they fail sufficiently to be benefited due to specific driving habit there are another kind of " foot is parked " driver.
These drivers stay in its foot on clutch pedal --- referred to as " stepping on by clutch " --- generates 15% pedal sometimes
Stroke, but when the vehicle is stopped briefly complete release the clutch pedal and is then again stepped on parked time clutch of its foot
Plate is jammed on being stepped on again by clutch pedal so that clutch pedal is jammed on back such as 15%.In driver by its heel
Often this " foot adjustment " occurs when reapposing more comfortable position.
Allow clutch to discharge/jam on threshold value (Th1) to change in the range of such as 10% to 30% fixation to adapt to
" foot is parked " (as described in the British patent file application No. is UK1206179.2) the result is that adjusting its foot in the manner described above
Driver may miss the chance of following engine stop.
When driver's complete release the clutch pedal during foot adjustment, this usually occurs when vehicle stops, and release/
Jam on maximum release limit value (such as 10%) that threshold value Th1 " will follow " always the foot of driver until its range.Clutch this moment
Device pedal state is shown as discharging.Later if foot is stayed on clutch pedal again and (return to 15%) by driver, and step on
Board position is by the release at 10%/jam on threshold value and therefore clutch pedal state becomes jamming on from discharging.
When stopping vehicle, if driver is parked by foot by this method before starting/halt system closes engine
It returns on clutch pedal, then, since clutch pedal is commanded the engine to stop in state is jammed in starting/halt system
Need release the clutch pedal before, then start/halt system will not close engine.In this case, driver is not
There is plan to prevent engine stop, and result makes engine unnecessarily use fuel.
Alternatively, if driver steps on parked time clutch of foot after starting/halt system has had been switched off engine
Plate is to generate jamming on greater than 10%, then pedal state will occur by discharging to the variation jammed on, this leads to starting/stopping system
System restarts engine.This is unfavorable when driver is not intended to restart engine, and engine will unnecessarily make
Use fuel.
In order to reduce this generation for missing engine stop chance, it is possible to reduce threshold range from 10% to 30%
To 20% to 30%, therefore the minimum limit value (20%) of range has been more than common foot rest position (15%).Although however, this
It is beneficial to the driver of " foot is parked " and " foot adjustment ", still, the driver of those complete release the clutch pedals (0%) is necessary
To jam on pedal (for example, the limit value for reaching 20%) more to reach release conditions and trigger engine start.They by this
It is perceived as the starting of less " sense of urgency " and leads to the increase for starting the time.

Specific embodiment
Referring to Fig.1, display has the motor vehicles 5 of engine 10 and stop/start system, the stop/start system
Including electronic control unit 16 and clutch pedal position sensing with electric clutch pedal position processor (EC3P) 16C
Device 26, the clutch pedal position sensor are set as the position of sensing clutch pedal 25.It should be appreciated that clutch pedal position
Set sensor 26 position of gaging clutch pedal 25 and need not can be directly connected to as shown in any convenient manner
To clutch pedal 25.For example but not limited to this, it can selectively monitor the piston position of clutch master cylinder.
In the exemplary situation, the output from clutch pedal position sensor 26 is converted into clutch pedal position percentage
Than wherein 0% jams on the clutch pedal 25 for indicating to discharge completely, and 100% jams on the clutch pedal for indicating to step toward bottom
25.It is understood, however, that being also applicable to other clutch pedals with identical technology described in text in other cases
The representation of position, for example, the level or magnitude of clutch pedal position sensor output signal.
It is to be further understood that EC3P 16C can be separate unit and be not necessarily formed as the portion of electronic control unit 16
Point.In addition, as described herein, EC3P 16C can execute assessment clutch pedal position required for all steps, and to
Electronic control unit 16 provides the output for showing whether engine 10 is to be stopped or starts, or will can only come from clutch
The signal of device pedal position sensor 26 is converted into the adjustment signal of filtering, and the adjustment signal of the filtering is electronically controlled unit 16
For execute assess clutch pedal position required for all steps and determine engine whether 10 it is to be stopped or starting.
In most cases, electronic control unit 16 and EC3P 16C are exactly as with application No. is UK1206179.2's
Component described in British patent file is constructed and is operated like that, thus will not be described in further detail herein.
Primary difference between content described in the present invention and British patent file application No. is UK1206179.2 is,
Whether the boundary to be arranged between transition zone " T " and release area " R " is being run based on engine 10 in the present invention, and is being applied
Number for UK1206179.2 British patent file in boundary be fixed.
Referring now to Fig. 2 and Fig. 3, wherein showing the motion range of clutch pedal 25 in a schematic way and for controlling
Specific three predefined areas of stopping and the starting of engine 10 processed.
With reference first to Fig. 2, wherein diagrammatically showing, engine 10 is not stopped, i.e. engine 10 is run
The case where, how EC3P 16C is based on jamming on the percentage of position completely for the output from clutch pedal position sensor 26
Signal processing is to operation area.
At region " R ", the control output from EC3P 16C will indicate that clutch pedal 25 is " release ", that is,
It says, meshing state will be in by the clutch of the moving operation of clutch pedal 25.
The region " P " locating for the biting point (bite point) of clutch, the control from EC3P 16C are exported table
Bright clutch pedal 25 " is jammed on ".
At transition zone " T ", the control output from EC3P 16C depends on position and the movement of clutch pedal 25.
In the case where shown engine 10 does not stop but is in operation, release area " R " is the lower limit by 0%
Value and the predefined fixed upper limit value Ll for being in the case 20%RIt limits.
Transition zone " T " passes through predefined lower limit value LlRIt is in the case 30% predefined fixed upper limit value
Lu is limited.Predefined fixed upper limit value Lu is selected, to make it have a position numerical value, which is lower than is stepped on by clutch
It the expection biting point for the clutch that plate 25 operates but is above the clutch pedal caused by the clutch pedal 25 is stepped on as driver
The position numerical value that 25 displacements generate.
Jamming on area " P " is that position (100%) restriction is jammed on by predefined fixed upper limit value Lu and maximum.
In addition removable motion tracking threshold value Th1 operation in transition zone " T ", and it is limited to lower limit value LlRAnd upper limit value
Lu.That is, Lu >=Th1 >=LlR。
It referring now to Fig. 3, diagrammatically shows, engine 10 is stopped, i.e. engine 10 not running
How situation, EC3P 16C will be believed based on the percentage for jamming on position completely from the output of clutch pedal position sensor 26
Number processing arrive operation area.
With as before, there are three regions " R ", " P " and " T " with feature as hereinbefore.
However, in the case, what engine 10 was off, release area " R " be by 0% lower limit value and 10% it is predetermined
Adopted upper limit value LlsIt limits.
Transition zone " T " is by predefined lower limit value LlsWith predefined upper limit value Lu limit, it is described it is predefined on
Limit value is set as 30% in the case.With as before, select predefined fixed upper limit value Lu, to make it have a position
Numerical value, which is lower than the expection biting point of the clutch operated by clutch pedal 25, but is higher than to be stepped on by driver and lean on
The position numerical value that the displacement of clutch pedal 25 caused by clutch pedal 25 generates.
It jams on area " P " position (100%) is jammed on by predefined fixed upper limit value Lu and maximum and limit.
Moveable tracking threshold value Th1 in transition zone " T " as run as before and being limited to lower limit value LlsWith it is upper
Limit value Lu.That is, Lu >=Th1 >=Ll in this cases。
Operation in transition zone is moved as described in the British patent file application No. is UK1206179.2
Threshold value Th1 tracks clutch pedal position (CP), so that it is always located in slightly biased to the direction mobile with clutch pedal 25
Opposite current clutch pedal position side, also referred to as conversion window.Therefore, if clutch pedal 25 is to complete release position
It is mobile to set 0%, then the threshold value Th1 moved will jam on side positioned at current clutch pedal position.
Similarly, if clutch pedal 25 is moved to position (100%) is jammed on completely, the threshold value Th1 moved will
Positioned at the release side of current clutch pedal position.
Application No. is Fig. 6 of the British patent file of UK1206179.2 and explanation related to this to be illustrated in more detail
With this track process.
Referring now to Fig. 4 A to Fig. 4 D, wherein four example disposition of the display clutch pedal position with time change
Condition.In all these situations, (100%) is jammed on completely before clutch pedal 25, to allow the speed changer of motor vehicles 5
(not shown) is placed in neutral state, and vehicle 5 has been braked to stopping and clutch pedal 25 is now by driver from greater than upper
The clutch pedal position of limit value Lu discharges.
In Fig. 4 A, driver operate clutch pedal so that its completely release (0%), and by the of short duration time it
Clutch pedal is jammed on again afterwards so that clutch pedal is mobile to position (100%) is jammed on completely.
It is removable since clutch pedal historical record is that clutch pedal has been jammed on to more than upper limit value Lu (30%)
Dynamic switching threshold Th1 will be raised to upper limit value Lu and therefore will be located at 30%.
Therefore, when clutch pedal to be moved to the position that slightly lower than 30% jams on as driver, as shown in point P1, threshold
Value Th1 will be through, and engine 10 will start to stop, because making to start from removable threshold value composition is crossed with stepping toward release
The trigger event that machine stops.When clutch pedal 25 continue when release direction moves further across transition zone " T ", move
Threshold value Th1 will track current clutch position, be at 3% in the case of this for jamming on side to be located at current clutch position.
However, when moveable threshold value Th1 reaches lower limit LlRWhen, as shown in point P2, moveable threshold value Th1 no longer with
With clutch pedal position, because it is limited to as lower limit value LlRThe numerical value of setting is 20% in the numerical value in this case.
Removable threshold value Th1 therefore still remain in it is 20% constant, as shown in the horizontal dotted line between point P1 and point P3.
In the time " t " for corresponding to point P3, engine speed (N) reaches zero and therefore engine 10 stops, and due to
The stopping of engine 10, lower limit value is by the limit value Ll that runs for engineRBecome the limit value Ll that engine is not runs.This
In the case of, the lower limit value for engine not operating status is arranged on 10%, and therefore, once engine 10 is in time t
Out of service, removable threshold value Th1 will be released and be quickly moved to new numerical value 10%, such as the conversion institute from point P3 to point P4
Show.
There is shown the time delay of several seconds, clutch pedal 25 discharges completely during this period, engine 10 stop and
Removable threshold value Th1 is maintained at 10%, and later, in time t ', driver start to jam on clutch pedal 25 so that its to
The direction jammed on completely is mobile.Engine 10 will not start immediately, because removable threshold value Th1 is located at 10%, and clutch is stepped on
Board position initially jams on less than it, still, once from the side jammed on is discharged into up over removable threshold value Th1,
It is to be located to occur the point P5 of time t2 ' in the case of this, engine 10 starts and lower limit value will be from the lower limit of engine stop
Value Lls(10%) it is moved to the lower limit value Ll of engine operationR(20%).However, starting if lower limit value is allowed to convert back immediately
Machine runs lower limit value LlR, then engine 10 will stop again, which is because, current clutch pedal position will then be fallen
In the release side of removable threshold value Th1, since either which lower limit value comes into force, removable threshold value Th1 cannot be below forever
Lower limit value, removable threshold value Th1 also are moved into 20% certainly.
In order to overcome this problem, it moves threshold value Th1 and lower limit value is set as falling behind about since engine start
3% ground tracks clutch pedal position until clutch pedal position reaches 23%, and removable threshold value Th1 has such as point P6 institute
20% numerical value shown.In point P6, lower limit value resets to the lower limit value L1 met for engine operating stateRNeeds
20%.
As clutch pedal 25 is further jammed on the direction jammed on by point P6, removable threshold value Th1 will continue to fall
About 3% ground tracking clutch pedal position is until clutch pedal position reaches 33% afterwards, and removable threshold value has number
Value 30%, as shown in point P7.Removable threshold value Th1 is limited to upper limit value Lu, thus it no longer tracks clutch pedal position
And it will remain in 30%, as shown in the horizontal line extended out as point P7.Removable threshold value Th1 will remain in 30% and jam on directly
Upper limit value is crossed again by jamming on side to clutch pedal 25.
Referring now to Fig. 4 B, driver operates clutch pedal 25 so that it is mobile to fully released position, but only makes
Its movement 15% jams on position and incomplete release (0%) to step on and lean on clutch.Then, pass through it in a small amount of time
Afterwards, driver, which jams on clutch pedal 25, keeps it mobile to position (100%) is jammed on completely.
It is more than upper limit value Lu (30%) since clutch pedal historical record is that clutch pedal jammed on, moves
Threshold value Th1 will be dragged at upper limit value Lu and therefore be located at 30%.
Therefore, when driver's release the clutch pedal 25 to as shown in point P1 ' be slightly lower than 30% jam on position when,
It will extend over threshold value Th1 and engine 10 will start to stop.It, can when clutch pedal 25 continues to be released in transition zone " T "
Mobile threshold value Th1 tracks current clutch position and jams on side be located at current clutch position.
However, when reaching lower limit value Ll as shown in point P2 'RWhen, removable threshold value Th1 no longer follows clutch pedal position
It sets, because it is limited to as lower limit value LlRThe numerical value of setting, in the case numerical value LlRIt is 20%.Removable threshold value Th1 because
This is maintained at 20%, as shown in the horizontal dotted line between point P2 ' and point P3 '.
Corresponding to time t0 ' point P3 ', engine speed (N) reaches zero and therefore engine 10 stops, also, by
In the stopping of engine 10, lower limit value is by the limit value Ll that runs for engineRBecome the limit value Ll not run for engines。
Lower limit value Ll for engine not operating statuss10% is arranged in the case, once and engine 10 it is out of service,
Moveable switching threshold Th1 by be released and be quickly moved to more than current clutch pedal position 3% new numerical value,
As from point P3 ' to shown in the conversion of point P4 '.Lower limit value LlsIt is moved to 10%, but removable threshold value Th1 cannot be followed always, because
If will be over current clutch pedal position to follow always.Therefore, although lower limit value LlsIt is arranged 10%, still
Removable threshold value Th1 be limited as resting on current clutch pedal position (15%) jam on side to prevent to restart immediately.This
The case where similar to from point P1 ' to P2 ', wherein tracking clutch pedal position, and used similar technology.
In the example shown, perhaps because vehicle may stop before red light, there are the time delays of several seconds.Herein
Timing period, clutch pedal 25 is maintained at 15% position that jams on, and engine 10 keeps stopping.
Then, in time t1 ', driver starts to jam on clutch pedal 25 so that it is mobile to position is jammed on completely.Hair
Motivation 10 will not start immediately, because removable threshold value Th1 is arranged 18%, still, once removable threshold value Th1 is crossed, this
Place is located at point P5 ', and engine 10 just starts.Lower limit value needs the lower limit value Ll by engine stop nows(10%) to starting
The lower limit value Ll of machine operationR(20%) mobile.However, if lower limit value converts back the lower limit value Ll of engine operation immediatelyR, that
It is by freewheel clutch pedal position and engine 10 stops again.The reason is that current clutch pedal position will be fallen
In the release side of removable threshold value Th1, since whichever lower limit value comes into force, removable threshold value Th1 cannot be below lower limit forever
Value, so removable threshold value Th1 also will be moved into 20%.
In order to overcome this problem, threshold value Th1 and lower limit value are moved and is begun through from engine start and fall behind small number
Clutch pedal position is tracked to value (being in this instance 3%) until clutch pedal position CP reaches 23%, in this time
The removable threshold value Th1 of point has the numerical value 20% as shown in point P6'.Lower limit threshold is incrementally adjusted using following transfer algorithms
Value.
In point P6 ', lower limit value is then reset to the lower limit value numerical value (Ll for engine operationR=20%) so that it is accorded with
Close the needs of engine operating state.
Make it that will continue to fall behind about beyond point P6 ', removable threshold value Th1 with clutch pedal 25 is further jammed on
3% ground tracks clutch pedal position until clutch pedal reaches 33%, and moving threshold value Th1 at this time has such as point P7 ' institute
30% numerical value shown.Then removable threshold value Th1 is limited to upper limit value Lu and therefore no longer tracks clutch pedal position, and
It is maintained at 30%, as shown in the horizontal line extended from point P7 '.Removable threshold value Th1 will remain in 30% and jam on until clutch
Device pedal 25 crosses upper limit value from jamming on side again.
Referring now to Fig. 4 C, driver operates clutch pedal 25 so that it jams on position movement to 0% discharged completely.
Driver then release the clutch pedal 25 so that its before engine stop from the position for jamming on position completely and being jammed on to 15%
Set movement.
Since clutch pedal historical record is that clutch pedal has been jammed on to more than upper limit value Lu (30%), move
Threshold value Th1 will be dragged to upper limit value Lu and therefore be located at 30%.
Therefore, when the position that driver's release the clutch pedal 25 to slightly lower than 30% jams on, such as shown in point P1 ",
It will extend over threshold value Th1 and engine 10 will start to stop.When clutch pedal 25 transition zone " T " continue release when, can
Mobile threshold value Th1 tracks current clutch position and jams on side be located at current clutch position.
However, when reaching the lower limit value Ll as shown in point P2 "RWhen, removable threshold value Th1 can no longer follow clutch pedal
Position CP, because it is limited to as lower limit value LlRThe numerical value of setting is 20% in the case.Removable threshold value Th1 is therefore
The numerical value for remaining in 20%, as shown in the horizontal dotted line between point P2 " and P3 ".
In time T2 corresponding with point P3 ", engine speed (N) reach zero and what engine 10 was off now.
Due to engine 10 time t2 stopping before driver in time t1 by clutch pedal by discharging completely
Position (0% jams on) jams on position movement to 15% immediately, and effect is similar to previously referring to described in Fig. 4 B.
At point P3 ", since engine 10 has stopped now, lower limit value is by the limit value Ll that runs for engineRBecome
Change to the limit value Ll not run for engines.Lower limit value Ll for engine not operating statussIt is arranged in the case
10%, once and engine 10 it is out of service, the threshold value Th1 of removable conversion will be released and be quickly moved to new number
Value, in this case, the current clutch pedal position of the numeric ratio more 3%, as shown in the conversion from point P3 " to point P4 ".Under
Limit value LlsIt is moved to 10%, but removable threshold value Th1 cannot follow always it, because removable threshold value will in this way crossed
Current clutch pedal position.Therefore, although lower limit value Lls10%, removable threshold value Th1 is limited as resting on current for setting
Clutch pedal position jams on side, to prevent from restarting immediately.
In the example shown, then there is the time delay of several seconds, wherein clutch pedal 25 is maintained at 15% and jams on position
And engine 10 keeps stopping.Then driver starts to jam on clutch pedal 25 so that it is to the position jammed on completely in time t3
Set movement.Engine 10 will not start immediately, because removable threshold value Th1 is arranged 18%, still, once cross removable threshold
Value Th1 occurs in this case in the time t3 ' for corresponding to point P5 ", then engine 10 starts.As previously mentioned, lower limit value L1 is existing
Needing the lower limit value Ll from engine stops(10%) the lower limit value Ll run to engineR(20%) mobile.However, if
Lower limit value L1 converts back the lower limit value Ll of engine operation immediatelyR, then it will be more than clutch pedal position, and engine 10
It will stop again.This is because current clutch pedal position will then fall on the release side of removable threshold value Th1, due to nothing
Effective by which lower limit value, removable threshold value Th1 cannot be below lower limit value forever, therefore move removable threshold value Th1 also will
It moves to 20%.
In order to overcome this problem, threshold value Th1 and lower limit value are moved since engine start with numerical value that backwardness is small
(such as 3%) track clutch pedal position until clutch pedal position reaches 23%, move threshold at this time point
Value Th1 has the numerical value 20% indicated with point P6 ".Lower limit value is converted using following algorithms.In point P6 ", lower limit value is then weighed
Set the lower limit value numerical value (Ll run for engineR=20%) to meet the needs of engine operating state.
As clutch pedal 25 further jams on, removable threshold value Th1 will continue to fall behind about 3% ground tracking clutch
Pedal position reaches 33% until clutch pedal position, and moving threshold value Th1 at this time has 30% as represented by point P7 "
Numerical value.Then removable threshold value Th1 is limited to upper limit value Lu, therefore it no longer tracks clutch pedal position and will remain in
30%, as shown in the horizontal line extended from point P7 ".Removable threshold value Th1 will remain in 30% and jam on until clutch is stepped on
Plate 25 crosses upper limit value by jamming on side again.
Referring now to Fig. 4 D, driver operates clutch pedal to be moved into release (0% jams on) position completely.It drives
Then the person of sailing jams on clutch pedal 25 in time t2 " ' and is moved into 15% position jammed on, but it is in this feelings
Occur under condition in engine after time t0 stopping.
Due to clutch pedal historical record be clutch pedal jammed on to be higher than upper limit value Lu (30%), it is removable
Dynamic threshold value Th1 will be dragged to upper limit value Lu and therefore will be located at 30%.
Therefore, when the position that driver's release the clutch pedal 25 to slightly lower than 30% jams on, such as shown in point P1 " ',
Threshold value Th1 will be crossed and engine 10 will start to stop.When clutch pedal 25 continues release in transition zone " T ",
Removable threshold value Th1 tracks current clutch position to jam on side positioned at current clutch position.
However, when reaching lower limit value LlRWhen, such as shown in point P2 " ', removable threshold value Th1 can no longer follow clutch pedal
Position, because it is limited to as lower limit value LlRThe numerical value of setting, the numerical value are 20% in the case.Removable threshold value Th1 because
This is maintained at 20% constant numerical value, as shown in the horizontal dotted line between point P2 " ' and point P3 " '.
In point P3 " ', engine speed (N) reaches as shown in point t0 zero and engine 10 stops now.
In point P3 " ', since engine 10 has stopped, lower limit value is by the limit value Ll that runs for engineRBecome such as point
The limit value Ll that engine shown in P4 " ' is not runs.Lower limit value Ll for engine not operating statussIt is arranged in the case
10%, once and engine 10 is out of service, the threshold value Th1 of removable conversion will be released and be quickly moved to new
10% numerical value, as from point P3 " ' to shown in the conversion of point P4 " '.
Lower limit value L1 is moved to 10% and moves threshold value Th1 always with its variation, because in this time point clutch
Device pedal position is jammed in 0%.
Driver starts to jam on clutch pedal 25 in time t2 " ' after very short time delay so that its to
15% jams on position movement, adjusts again this is because placement of foot occurs, to step on by clutch.Because lower limit value L1 is arranged now
It is not run for engine or the horizontal Ll of engine stops, so engine 10 will cross point P8 " ' in clutch pedal position
The lower limit value Ll at placesShi Qidong, this is because removable threshold value Th1 is also disposed at 10%.
Because engine 10 is operation now, lower limit value needs the lower limit value Ll from engine stop nows(10%)
The lower limit value Ll run to engineR(20%) mobile.
However, if lower limit value converts back the lower limit value Ll of engine operation immediatelyR, then it will be more than clutch pedal
Position, and engine 10 will stop again.This is because current clutch pedal position will fall in releasing for removable threshold value Th1
Side is put, due to whichsoever lower limit value (LlROr Lls) come into force, removable threshold value Th1 cannot be below lower limit value forever, so
Removable threshold value Th1 also will be moved to 20%.
In order to overcome this problem, it moves threshold value Th1 and lower limit value is set as by engine start i.e. in a small amount
(such as 3%) is lower than clutch pedal position, until clutch pedal position CP reaches 15% in point P10 " ', at the time point
Removable threshold value Th1 has the numerical value 12% indicated with point P9 " '.
Driver then keeps clutch pedal 25 to be jammed on to 15% in short time and jams on position in this instance, such as horizontal
Shown in line P10 " ' to P5 " '.
During the period by P10 " ' to P5 " ', removable threshold value Th is held together in 12% together with lower limit value, the lower limit
Value is limited to the fact that it is no more than clutch pedal position.
In point P5 " ', driver starts to jamming on the mobile clutch pedal in position completely, and lower limit value is together with removable threshold
Value Th1 falls behind 3% ground now and is followed by clutch pedal position to engine operation lower limit value LlR(20%), such as point P6 " ' institute
Show, here, clutch pedal position is 23%, because removable threshold value Th1, which falls behind 3% ground, tracks clutch pedal position.
In point P6 " ', lower limit value resets to the lower limit value numerical value (Ll of engine operationR=20%) to meet engine operation
The needs of state.
As clutch pedal 25 is jamming on further jamming on for direction, removable threshold value Th1 will continue to fall behind about 3%
Ground tracks clutch pedal position until clutch pedal position reaches 33%, and moving threshold value Th1 at this time has with point P7 " '
The numerical value 30% of expression.Then removable threshold value Th1 is limited to upper limit value Lu, therefore it no longer tracks clutch pedal position simultaneously
30% will be remained in, as shown in the horizontal line extended from point P7 " '.Removable threshold value Thl will remain in 30% and jam on directly
Upper limit value is crossed by jamming on side again to clutch pedal 25.
Therefore in this case, by engine 10 stop but then when its foot stays in clutch pedal again
The fact that starting, driver feedback is given, i.e. the repositioning behavior of its foot is reduced for stopping engine 10 to save combustion
The chance of material.
Stop/start system, which can be configured, steps on it not to detect such case and provide to visualize to alert to driver
By clutch pedal 25.
Referring to Fig. 5, show in summary form control according to the present invention the stopping of the engine 10 of motor vehicles 5/
The method of start-up operation, this method are by electronic control unit 16 and/or electric clutch pedal position processor 16C
Many algorithms and operation sequence are realized.
This method is since step 310, it determines that engine 10 is off or not being off here.
If engine 10 has stopped, method proceeds to step 320, and the upper limit value for transition zone " T " is under herein
Limit value (Lu and Lls) be respectively set to 30% and jam on jam on 10%.
Then method proceeds to step 325, it checks whether that engine 10 is operation here, that is to say, that engine
10 are not off.If engine 10 be not operation, that is to say, that engine 10 was off, then method continue with
Identical upper limit value Lu and lower limit value Lls constantly cycle through step 325, until the state of engine 10 becomes " not stopping
Only ".
If be not off in step 325 discovery engine 10, that is to say, that engine 10 just starts or has been started up,
So method proceeds to step 328.In step 328, the level that the case where lower limit value for engine by not running is arranged is (in this example
In be Lls=10% jams on) to be incremented to hair be the level that is arranged of the case where engine is run (is in this instance LlR=20% jams on).
Importantly, lower limit value is no more than clutch pedal position, because this will lead to converts back engine stop immediately
State.
Therefore in order to realize this target, using the lower limit value of algorithm setting conversion until reaching lower limit value LlR, such as:
Rl(t)=MIN(RlR, Max (Rl (t-1), Th1))
Wherein:
Rl (the t)=conversion lower limit value to be arranged；
The upper numerical value of Rl (t-1)=conversion lower limit value setting；
Th1=removable threshold value current value；And
LlRThe predefined numerical value of=lower limit value numerical value being selected as when engine is run.
If 20% is used as lower limit value Ll when being chosen as engine operationRNumerical value predefined numerical value, then :-Rl
(t)=MIN (20, Max (Rl (t-1), Th1))
That is, Rl (t) is equal to 20% minimum value, or the preceding numerical values Rl of last circulation (iteration)
(t-1) or the maximum value in current value the two of removable threshold value Th1 --- take it is biggish that.
For example, if :-Th1=14% and Rl (t-1)=12%
Rl (t)=Min (20% and Max (14% or 12%))
Rl (t)=Min (20% or 14%)
Rl (t)=14%
As further example, if :-Th1=22% and Rl (t-1)=19%
So Rl (t)=Min (20 and Max (22 or 19))
Therefore in this case, Rl (t)=20%
It is to be appreciated that the numerical value used in an illustrative manner not limits, it can be based on each clutch actuation system
Structure and feature use other upper limit values and lower limit value, and numerical value can be signal level rather than percentage.
It is to be appreciated that the lower limit value Ll of engine operationRIt must be provided with higher, that is to say, that ratio is due to motor vehicles
Driver steps on the position more jammed on by being expected clutch pedal position caused by clutch.Therefore, in the example given, by
In assuming that it is 15% to jam on that driver's clutch, which is stepped on by position, lower limit value LlRIt is arranged 20%.
It should be appreciated that the lower limit value Ll that engine is not runsIt must be provided with lower, that is to say, that ratio is due to motor vehicle
Driver steps on by expected clutch pedal position less jams on caused by clutch position.Therefore, in the example given,
Being stepped on due to driver's clutch by position is 15% to jam on, lower limit value LlsIt is arranged 10%.
Although the numerical value of the lower limit value of in the example given for engine operation the case where is 20%, it should be understood that
If not necessarily in this way, having used 30% upper limit value Lu, for engine operation the case where lower limit value LlRIt can be
18% to 25% jams in range.
Similarly, although the numerical value Ll for the case where being used for engine stopsIt is provided with 10%, it is not necessary in this way, lower limit
It is worth numerical value LlsIt can be jammed in range 6% to 12%.
It will be understood by those of skill in the art that although describing this with the way of example referring to one or more embodiments
Invention, but it is not limited to the disclosed embodiments, and without departing from model of the invention defined in the appended claims
In the case where enclosing, alternate embodiment can also be constructed.
