The dynamic equipment engaging clutch；And/or for if it is determined that the input speed (n of variator31) less than predetermined threshold (nMin, 2),
The most automatically operate the equipment of internal combustion engine；And/or for if it is determined that the input speed (n of variator31) less than predetermined threshold
(nMin, 1), then automatically send the equipment of the information engaging predetermined gear.For said purpose, the present invention also proposes a kind of vehicle,
Particularly passenger vehicle, it include variator, at least one be connected to the driven pulley of described variator, internal combustion engine, for coupling
Variator and the clutch of internal combustion engine, and described equipment.The invention allows for advantageous embodiment.
According to an aspect of the present invention, a kind of vehicle, including variator, one or more driven pulleys, it is specially permanent
Be connected to described variator, be specially connected to the one or more output shaft of described variator, internal combustion engine, and clutch,
This clutch is used for making variator (specially its power shaft) and internal combustion engine be coupled to each other.
According to an embodiment, variator is included for being coupled the power shaft of internal combustion engine by clutch and being connected to
At least one output shaft of one or more driven pulleys, specifically, at least one output shaft described aligns with power shaft or parallel.
The input speed of variator can especially one speed, the specifically power shaft of variator rotate or rotate speed.
According to an embodiment, variator be have at least two, preferably have at least four and particularly have to
The manual transmission of the forward with different gear ratio of few five, wherein, the gear constituting bigger gear ratio is usual
Being referred to as relatively low-grade location, described gear ratio is the speed speed divided by the output shaft of variator of the power shaft of variator.Such as,
One gear constitutes bigger gear ratio than the second gear.
According to an embodiment, described gear can manually be braked speed change loader (specifically gear lever) and distinguish
Engage, or engaged.According to embodiment, variator mechanically or electronically is operated.
According to an embodiment, variator includes two or more, and especially at least four or five are arranged in power shaft
On different gears, it can be, optionally, coupled to power shaft by synchronizer.Described gear is permissible, specifically for forever
Ground, embeds (cog) or interacts respectively with the corresponding different gears being pivotally affixed to countershaft, and described countershaft can be special
The output shaft of variator it is connected to by other gear trains.Alternatively, the gear of power shaft can be permanently embedded especially or
Interact respectively with the corresponding different gear being pivotally affixed to output shaft itself.Therefore, by alternately through same
Step equipment makes the different gears on power shaft be connected to described axle, it is alternatively possible to engage different gears, thus constitutes difference
Gear ratio.
According to another embodiment, variator includes two or more, and especially at least four or five are arranged in one
Or the different gears on multiple output shaft, it can be, optionally, coupled to corresponding output shaft by synchronizer.Described gear
Of course, the most for good and all, embed or distinguish phase with the corresponding different gear of the power shaft being pivotally affixed to variator
Interaction.Therefore, by making the different gear being connected on power shaft be connected on described axle by synchronizer alternatively,
It is alternatively possible to engage different gears, thus constitute different gear ratio.
Gear at variator is not engaged, and/or the power shaft of variator and output shaft separated from one another in the case of,
Especially, variator is referred to as being in neutral.
According to an embodiment, clutch is operated electrically, i.e. described clutch is electric clutch, especially electricity
Magnet clutch (especially " e-clutch " or " EM ").
According to an aspect of the present invention, if it is determined that the input speed of variator is respectively smaller than or is less than predetermined threshold, exist
Under cruise mode, engage the information of predetermined gear automatically, the most visually, audibly and/or sense of touch ground send to drive
Member.
Described predetermined gear can determine based on the current gear engaged.Specifically, lower one than the current gear engaged
Or the gear of multiple rank or quantity can be determined that described predetermined gear.Such as, if currently engaging sixth speed position, pass through
Respectively from sixth speed potential drop one or two rank low, the 5th or fourth speed position can be determined that predetermined gear.Therefore, according to
One embodiment, predetermined gear is the gear more relatively low than the current gear engaged, and particularly closes on relatively low gear.
Predetermined gear is also based on the present speed of vehicle or the current rotating speed of the output shaft of variator and determines, especially
When being not have gear to be engaged, i.e. variator is in neutral gear.Such as, if the speed of vehicle is between 40km/h and 45km/h,
Then fifth speed position is confirmed as predetermined gear, and if the speed of vehicle between 35km/h and 40km/h time, then fourth speed position
It is confirmed as predetermined gear.In one embodiment, if the speed of vehicle is relatively low speed, the most predetermined gear is low or first gear
Position.
By the low gear specified by engagement signal, in one embodiment, power shaft will be traveling one of vehicle
Or multiple driven pulley accelerates, thus reduce the possible pressure of synchronizer, this pressure due to power shaft and gear thereon it
Between or speed difference the most excessive between output shaft and gear thereon.Therefore, according to an embodiment, cruise mode
Time and cycle can be correspondingly advantageously extended.
According to a further aspect in the invention, in cruise mode, if it is determined that the input speed of variator is less than or is less than
Identical or another predetermined threshold, then clutch automatically engages, and the clutch particularly separated is re-engaged, or the clutch engaged
Device remains engaged with, and/or internal combustion engine operation, and the internal combustion engine particularly shut down is activated, or the internal combustion engine of operating keeps fortune
Turn.
Operating internal combustion engine, particularly starts the internal combustion engine that shuts down, can add the defeated of speed transmission in one embodiment
Entering axle, this is to be realized by drag torque (drag torque), if clutch separation, or more directly by connecing
Close or be re-engaged clutch to realize.This acceleration can advantageously reduce the possible pressure of synchronizer in one embodiment
Power, this pressure is due to the biggest between power shaft and gear thereon or between output shaft and gear thereon
Speed difference.
And, by engaging clutch, especially it is re-engaged the clutch of separation, can be the most favourable
Ground reduces the possible pressure of synchronizer.
Especially, as described above, the internal combustion engine making power shaft be connected to operate by engaging clutch can be one
Power shaft is directly accelerated by individual embodiment.
Additionally or alternatively, at internal combustion engine operation or in the case of shutting down, engaging clutch can be an enforcement
In example, advantageously speed at power shaft becomes at a fairly low to such an extent as to engages the gear of low speed and may (exceedingly) compressing synchronization set
For terminating cruise mode before.
Especially, if engaged gear under cruise mode, engage or be re-engaged clutch and will make to be connected to internal combustion engine
Vehicle deceleration or again slow down, thus directly transmit signal to driver so that it is according to similar with traditional manual transmission
Mode downshift.Therefore, according to an embodiment, driver advantageously need not be suitable for patrolling by his or her driving style
Model plane formula.
Additionally or alternatively, if it is determined that the input speed of variator is less than predetermined threshold, engages or is re-engaged clutch
Device can advantageously be avoided making internal combustion engine stall or flame-out in one embodiment.
In particular, it was found that in cruise mode, driver is more likely shifted to from neutral gear rather than from high gear
Inadequate low gear (and therefore possible (exceedingly) compressing synchronizer).In one embodiment, owing to being shifted to sky
Shelves by make no longer by vehicle one or more driven pulleys drive power shaft rotating speed reduce, thus be shifted to neutral gear and because of
This increases and is shifted to the probability of inadequate low gear subsequently, whereby may can be a reality to the compressing of synchronizer
Execute the input speed being determined by variator in example to detect less than predetermined threshold.Engage the most in this case or again connect
Close clutch and thus terminate cruise mode, can the most advantageously reduce be shifted to subsequently inadequate low
The probability of speed gear, and reduce the compressing to synchronizer of the possibility (exceedingly) therefore.
According to an embodiment, when variator is in neutral, if or when clutch joint and internal combustion engine are in operating
Time, cruise mode can be kept: if determine the input speed of variator (when especially internal combustion engine cuts out) when neutral gear cruises
Less than predetermined threshold, according to an embodiment, then internal combustion engine is started by trigger, and clutch is engaged, and is particularly rising
After dynamic internal combustion engine.Therefore, the power shaft of variator is driven under the idling (idle sailing) of the internal combustion engine operated
Dynamic.This state can remain " idling cruise ", because the danger exceedingly oppressing synchronizer is restricted.
Above-mentioned two aspects can be implemented separately or together.Therefore, in an embodiment, if it is determined that the input speed of variator
Less than the first predetermined threshold, the most automatically send the information engaging predetermined gear, and, if it is determined that the input speed of variator
Less than the second predetermined threshold, it is less than or less than the first predetermined threshold, then clutch engages and/or internal combustion engine operation.
So, according to an embodiment, driver advantageously been proposed in cruise mode by engaging clutch and/or fortune
Before forwarding motivation to terminate, downshift is to extend cruise mode time or cycle.
According to an embodiment, predetermined threshold, the specifically first and/or second predetermined threshold, can idle from internal combustion engine
Speed deviation is less than 10%, especially no more than 5%.This can optimize cruise mode time or cycle and/or favourable especially
Cruise in idling.According to another embodiment, predetermined threshold, the specifically first and/or second predetermined threshold, can be from internal combustion engine
Idling deviation at least 15%, particular at least 20%.This can reduce the probability of (excessively) compressing synchronizer especially.
Preferably, predetermined threshold is more than or less than or is equal to the idling of internal combustion engine.Additionally or alternatively, the first and second predetermined thresholds can
Offset with one another less than 10%, in particular according to an embodiment less than 5%.This time that can optimize cruise mode or week
Phase.According to another embodiment, the first and second predetermined thresholds can offset with one another at least 15%, particular at least 20%.This
The time to informational response can be extended.
According to an embodiment, internal combustion engine operation, the internal combustion engine particularly shut down is by engaging clutch start.Special
Not, if engaged gear, engaging clutch can start internal combustion engine advantageous by the kinetic energy of driving vehicle.Additionally or can
Selection of land, internal combustion engine can operate, and the internal combustion engine particularly shut down can be started by trigger, particularly due to input
When rotating speed is in before engaging clutch less than predetermined threshold in neutral cruise.
According to an embodiment, operate internal combustion engine, particularly starts the internal combustion engine that shuts down, alternatively or selectivity ground
In the gear of the speed of vehicle and/or the joint of variator respectively by engaging clutch or being performed by starter.Special
Not, if the speed of vehicle exceedes predetermined threshold, it can reduce numerical value or increase the gear ratio of gear engaged, and such as the
The gear ratio of five gears is more than the gear ratio of sixth speed position, and according to embodiment, internal combustion engine operation, especially by engaging clutch
Start, because enough moments of torsion are input to power shaft and the internal combustion engine of variator by this.Therefore, if the speed of vehicle determines low
In predetermined threshold, internal combustion engine operation, start by trigger in particular according to embodiment because determine joint clutch will no longer by
Enough moments of torsion are input to power shaft and the internal combustion engine of variator.According to an embodiment, if variator is in neutral, start
The internal combustion engine shut down is performed by trigger.
According to an embodiment, if clutch engages and/or internal combustion engine operation, cruise mode terminates, especially because
Determine that the input speed of variator is less than predetermined (second) threshold value.When cruise mode terminates, the auto-speed of vehicle controls phase
It is activated or starts with answering, being particularly useful for the speed the maintaining vehicle speed when cruise mode terminates.Implement according to another
Example, if variator is in neutral to maintain idling cruise, if clutch engages and internal combustion engine operation, especially because really
The input speed determining variator is less than predetermined (second) threshold value, then cruise mode is maintained.If it is determined that driver starts gear shift
Gear outside neutral gear, clutch can be automatically separated to allow this gear shift.
According to an embodiment, if cruise mode is unlocked, when the vehicle is running, clutch is separated and/or internal combustion
Machine is closed or turns off, and is based particularly on speed input, particularly bend the throttle.
As from aforementioned clearly visible, the feature of cruise mode can be, vehicle travels, and advances especially and/or place
In at least minimum speed, and clutch the most automatically, be based preferably on speed input and separate.Additionally or alternatively, patrol
The feature of model plane formula can be, vehicle travels, and particularly advances and/or is at least minimum speed, and internal combustion engine is special
It not automatically, be based preferably on speed input and close or shut down.Cruise mode is further characterized in that variator
Being in neutral, particularly clutch engages or separates.In another embodiment, the feature of cruise mode can be to be different from
Neutral, forward is engaged.According to an embodiment, when the output shaft of electromotor maintains static or idling, particularly when
When clutch engages, closedown or the internal combustion engine that shuts down be provided without fuel and/or igniting.
According to an aspect of the present invention, for operating the system of vehicle, described vehicle has variator, at least one connection
To the driven pulley of described variator, internal combustion engine and for coupling the clutch of variator and internal combustion engine, described system include for
Determine that transmission input is less than the equipment of predetermined threshold, and at least one of which equipment is for if it is determined that variator is fast
Degree, less than predetermined threshold, engages clutch the most automatically, for if it is determined that speed, transmission is less than predetermined threshold, particularly certainly
Before dynamic joint clutch, the equipment of the internal combustion engine that the most automatically operates, and for if it is determined that speed, transmission is less than predetermined threshold
Value, then aut sign is to engage the equipment of predetermined gear.
According to an embodiment, include for engaging clutch and/or opening according to the described equipment of one aspect of the invention

Detailed description of the invention
Fig. 1 shows vehicle according to an embodiment of the invention, and it includes manual transmission 31-38, is connected to described change
Speed two driven pulleys 40 of device 31-38, internal combustion engine 10, for making the electric power behaviour that variator 31-38 and internal combustion engine 10 be coupled to each other
The clutch 20 made, and for performing with reference to Fig. 2, the equipment of method according to an embodiment of the invention described by 3, its tool
There are computer or the form of ECU 50, described equipment and internal combustion engine 10, the clutch 20 of electric power operation and determine variator
The input speed n of 31-3831Sensor communication.
Described variator includes the power shaft 31 for being coupled internal combustion engine 10 by clutch 20, and described power shaft is with input
Rotating speed n31Rotating, described variator also includes the output shaft 38 being directed at power shaft 31 being connected to driven pulley 40.Variator bag
Include the forward with different gear ratio, illustrate the 5th and sixth speed position or high tap position the most for illustrative purposes.
Fifth speed position is made up of gear 32, and gear 32 can be connected to power shaft 31 by synchronizer 34, and engages
Being fixed to the gear 35 of countershaft 37, described countershaft 37 is connected to the output shaft 38 of variator by another group gear.Equally, the 6th
Gear is made up of gear 33, and gear 33 can be connected to power shaft 31 by synchronizer 34, can be connected to the 5th alternatively
The gear 32 of gear, and engage the gear 36 being fixed to countershaft 37.
Schematic variator 31-38 is only used as an embodiment and is understood.In another unshowned embodiment, axle 37
May be constructed gear 35,36 and be fixed to power shaft thereon.Described power shaft 37 subsequently can be alternately through clutch 20
Receive internal combustion engine 10.In this embodiment, axle 31 constitutes one of an output shaft or two possible output shafts, institute therewith
State the differential gear that output shaft can be directly coupled to be represented by circle in Fig. 1.Axle 38 does not exists, or and axle
31 are integrally formed.
With reference to Fig. 2,3, describe in further detail the method performed by ECU 50 according to embodiments of the present invention.
At time point t0(see Fig. 2), when ECU 50 starts cruise mode based on bend the throttle (not shown), car
Travel on sixth speed position (representing in Fig. 2) with " VI ".Because this cruise or the cruise mode of indication are known in the present invention
, so no longer it being described in more detail.In cruise mode, clutch 20 separates and internal combustion engine 10 cuts out.
Sixth speed position remains engaged with, and i.e. remains coupled to power shaft tooth at cruise mode lower gear 33 by synchronizer 34
Wheel 31.When car speed v reduces due to the factor such as aerodynamic drag, friction, the input speed n of power shaft 3131Also reduce, such as figure
Shown in thick line in 2 and right side arrow.
If the gear that driver downshifts the lowest (such as first or second gear), then with input speed n31Fall
Low, dangerous increase.The gear of these low gear can be connected to power shaft 31 alternately through synchronizer 34, for example,
Citing has been described above with reference to the gear 32,33 of the 5th and sixth speed, and the gear of these low or first gears is due to by big speed change
Ratio couples with driven pulley 40, so still can be with high-speed rotation.Therefore, synchronizer 34 must be compensated at the fastest gear rotated
The input speed n of the reduction with power shaft 3131Between bigger speed difference.In an alternative embodiment, axle 31 constitutes output shaft, axle
37 constitute power shaft (in Fig. 1, axle 38 is omitted or is integrally forming with axle 31, and variator rotates 180 °), and synchronizer 34 must
Must compensate output shaft 31 and with input speed n31Bigger speed difference between the gear of this low gear coupled.
In order to avoid the pressure by possible (excessively) of synchronizer 34, according to embodiments of the invention, ECU 50 holds
Row following methods.
In step slo, determine whether vehicle is in cruise mode.If not in cruise mode (S10: " N "), should
Method returns step S10 until being in cruise mode.Be in cruise mode or be not at cruise mode can be by an embodiment
Middle labellings etc. represent.
If being in cruise mode (S10: " Y "), then the method performs step S20.In step S20, determine that input turns
Speed n31Whether less than predetermined Second Threshold nMin, 2。
If it is determined that input speed n31Not less than predetermined Second Threshold nMin, 2(S20: " N "), then the method performs step
S40。
Determine input speed n in step s 4031Whether less than predetermined first threshold nMin, 1, this predetermined first threshold is more than
Or higher than predetermined Second Threshold nMin, 2, described Second Threshold and first threshold are represented by dotted line and chain line the most respectively.
If it is determined that input speed n31Nor less than predetermined first threshold nMin, 1(S40: " N "), the method returns step
S10。
If determining input speed n in step S4031Less than predetermined first threshold nMin, 1(S40: " Y "), then the method is held
Row step S50.
In step s 50, the information of predetermined gear of engaging is sent.As in Fig. 2 it can be seen that, at time point t1, input
Rotating speed n31Drop to predetermined first threshold nMin, 1Below.Therefore at this time point, the information (S50: " V of fifth speed position is engaged！”)
It is sent to driver.The method returns step S10 subsequently.
In the exemplary embodiment of Fig. 2, above-mentioned information is made a response and downshifts at time point t2 by driver
Five gears (are indicated by " V "), thick line in Fig. 2 and right side arrow upwards represent.
Power shaft 31 and input speed n thereof are accelerated in this operation31, as in figure 2 it is shown, because now power shaft 31 is by the 5th
The bigger gear ratio of gear is connected to driven pulley 40.Therefore cruise mode is at t2Can well be kept later.
Reduce further due to the factor such as aerodynamic drag, friction along with car speed v, the input speed n of power shaft 3131Again
Secondary reduction, if Fig. 2 is from time point t2Shown in the thick line extended and left arrow.
Therefore, in step s 50, rotating speed n is simply entered31Again drop to predetermined first threshold nMin, 1Hereinafter, just transmission connects
Close the information of predetermined gear.Predetermined gear indicated by signal can be close on less than the fifth speed position that engaged at present or
Fourth speed position based on vehicle present speed (not shown).
In the illustrative examples of Fig. 2, driver does not reacts to that, and the fourth speed position that do not downshifts.Therefore, with
Car speed v and reduce further due to the factor such as aerodynamic drag, friction, the input speed n of power shaft 3131Final at time point
t3It is down to predetermined Second Threshold nMin, 2Below.
Therefore, now in step S20, determine input speed n31Less than predetermined Second Threshold nMin, 2(S20: " Y ").Cause
And, the method performs step S30.
In step s 30, the gear that present speed v and variator 31-38 based on vehicle is engaged, ECU 50 is electrically
The clutch 20 making separation is re-engaged (S30: " 20=" 1 " "), and alternately through engaging clutch 20 or by activating
Starter (not shown) starts the internal combustion engine 10 (S30: " 10=" 1 " ") shut down.In the exemplary embodiment of Fig. 2, speed
Degree v exceedes the predetermined threshold of fifth speed position.Accordingly, because enough moments of torsion be passed to variator power shaft 31 and and its
The internal combustion engine 10 coupled, so internal combustion engine 10 starts by engaging clutch 20.
Owing to fifth speed position is engaged, the clutch 20 of joint makes vehicle deceleration (not shown in Fig. 2), thus directly to driving
The person of sailing sends the signal of downshift further, by the mode being familiar with traditional manual transmission.Therefore, driver is advantageously not required to
Its driving habits is made to be adapted to cruise mode.
In step s 30, cruise mode terminates (S30: " S=" 0 " "), and the auto-speed of vehicle controls in step S60
In activated, to be maintained at the speed v (t of vehicle when cruise mode terminates3).By auto-speed control, can again build
Vertical cruise mode (S10: " S=" 1 " ").
As understood from above illustrative examples, if the gear engaged under cruise mode is enough
Time, driver obtains good suggestion (Fig. 2: t before downshift1；Fig. 3: S50).If it is not this is reacted by he or she and defeated
Enter the input speed n of axle 3131It is reduced to the second predetermined threshold nMin, 2Below (Fig. 2: t3；Fig. 3: S20 " Y " "), then cruise mode
Terminating, clutch 20 is re-engaged, and internal combustion engine 10 is started by the joint of trigger or clutch 20.Accordingly, because it is right
The low input speed n of power shaft 3131The tooth of the relatively low gear on (reducing due to the higher gear of joint) and power shaft 31
Bigger speed difference between the high rotating speed of wheel is compensated, the probability of the pressure by possible (excessively) of synchronizer 34
It is minimized.
