The method described in this publication is related to the natural travel situations of normal running, may combine and slide
(Segeln) starting/stopping is slided in other words, needs this to slide to be in vehicle in movement.
In the case where putting clutch into operation for the first time, workshop is installed in vehicle in other words or under service scenario, is led to
Often do not take (zugegriffen) natural travel situations because or one cause the travel situations vehicle run due to mistake
Accidentally put that also at all infeasible or because vehicle can not be moved correspondingly due to live specified criteria into operation.
The utilization that the motor during stationary vehicle mentioned in this publication slows down actually is difficult, because
The time that can be used for being adapted in the case where 500 to 800U/min idler revolutions is especially short, until it is static to reach motor.
Summary of the invention
In this context, it introduces a kind of for being adapted to the method and a kind of system of the friction clutch of automation.Implement
Mode in this specification by obtaining.
Therefore, in the method introduced, an adaptation torque is applied by friction clutch to observe motor rotary speed
(eindeutig) of univocality changes.In the case, in the implementation of motor, friction clutch can be made according to the difference of load
Device is braked strongly or weaker.It is described to load the tracking for acting through revolving speed for motor rotary speed to detect and evaluate.
The clutch (R ü cken) of friction clutch is it is meant that the clutch disc of clutch mutually moves to transports together or mutually
It is dynamic to leave.The engagement (Einr ü cken) of friction clutch is interpreted as the gradual closure of the clutch disconnected at the beginning, in this feelings
Under condition, clutch has different bonding stations.Therefore, the friction clutch is purposefully engaged, during this period, control
Device obtains a signal, is motor rotary speed in this case, calculates at least one when necessary from the trend for the value of revolving speed
Gradient and the gradient is evaluated, to determination, if reached sensing point.It is described as follows process using disengaging (Ausr ü cken),
In the case where the process, clutch disc is moved mutually apart, therefore clutch is disconnected.Therefore, in this regard using general
Clutch expression is read to engage or disengage.
Therefore in the case where static vehicle, for example in transmission belt end or under service scenario, clutch system
It is feasible for putting into operation for the first time.Here, " artificially " causing to promote the corresponding rim condition for adaptation in other words.
A kind of method is described, in the method, and difference described in 10 2,013 208 256 A1 of publication DE, no
It is to utilize the motor decelerating phase (Motorauslaufphase) until motor stopping, but the rotary speed threshold value from one is utilized to open
Begin up to the range of speeds of the intervention of motor idle running adjusting.The range of speeds is purposefully set by described method
And for being adapted to.
Therefore, the known method supplemented with one adaptation of setting in motor slows down, to be provided more to adaptation
It time and therefore can be effectively adapted to.
It should be noted that in order to realize the adaptation more than idler revolutions, internal combustion engine of the idler revolutions in operating
In the case where either via diagnostic test device or via a storage program in the controller, swept in other words similar to a scanning
Test (Abtast- bzw. Scantest) is retouched, is raised in order in upper rpm level needed for sensing point adaptation.If reached
Above situation has been arrived, then has terminated revolving speed raising by a corresponding exerciser order, internal combustion engine is placed to inertia traveling
(Schubbetrieb) in and start aptamer sequence (Adaptionssequenz).Revolving speed raising start before and/or
Aptamer sequence should be tested before starting, and abide by the boundary condition for executing sensing point adaptation, such as clutch disconnects, interior
Combustion engine revolving speed is sufficiently high for adaptation, and gear has been linked into, and service brake (Betriebsbremse) has manipulated and motor
It does not light a fire.
In one embodiment, which it is real to be fully automated ground after it has been pushed (angesto en) primary
It applies and can also repeat in multiple times when necessary, such as the confidence level in order to examine adaptation result.
In a kind of embodiment of alternative, it is undesirable that realizing the automation of motor rotary speed by diagnostic test device
It improves, then motor rotary speed is improved by gas pedal.This can perhaps be guided by the information of one side of diagnostic test device or
It can also be implemented by the prompt of the display on vehicle.
Method described herein is responsible for, and the state that do not light a fire slowed down for the motor with subsequent motor stopping is from one
It is imported in the idler revolutions for being suitable for adaptation improved.The time that can be used for being adapted to is in this case than in general common
Situation under revolving speed is grown more than twice, to significantly improve the fastness of adaptation.
The required rpm level for raising from different vehicles is specific and the specific parameter of travel situations in
Out, such as:
1. the revolving speed gradient that motor slows down, interior friction, ancillary equipment
The high load of high gradient, that is high friction ancillary equipment in other words, it is desirable that higher rpm level,
Thus it enables that adaptation duration remains unchanged.
2. the dynamic of the clutch system friction clutch in other words of automation, that is to say, that must during motor slows down
An adaptation torque must be capable of providing
In the dynamic situation of the very little of clutch system, need more times, to provide detection torque or
It says in the case where being directed in turn, from provided detection torque, disconnects power assembly system.More for adjustment process
It is eliminated in the adaptation duration that more time improves one, this must be compensated by higher rpm level.
3. the temporal resolution (Aufl sung) of Rotating speed measring must be recognized reliably, that is to say, that variation, such as
Via the filtering of multiple measured values
In the case where the temporal resolution of the very little of rotating speed measured value, extend measurement interval, so as to reliably examine
It surveys and evaluates rotation speed change.Extended measurement interval needs extended adaptation duration and therefore also needs turn improved
It is fast horizontal.
In another embodiment, revolving speed is increased on a fixed high revolving speed, such as is increased to motor maximum and turns
In speed.In another embodiment, it only increases to for reliably identifying required rpm level.

Specific embodiment
The present invention is schematically illustrated by embodiment in the accompanying drawings and is then retouched in detail in the case where reference attached drawing
It states.
Fig. 1 shows the power assembly system of motor vehicle, is indicated using appended drawing reference 10.The diagram illustrate an internal combustions
Machine 12, a friction clutch 14, a speed changer 16 and driven wheel 18.Therefore, using friction clutch 14 can in
It is disconnected and be closed the power assembly system 10.This passes through the clutch of friction clutch 14, that is, is engaged or disengaged to carry out.?
This, the clutch disc 20 of friction clutch 14 is mutually moved to together or is moved mutually apart.An actuator 22 is used thus,
It is manipulated again by a controller 24, such as motor controller.A control signal is used thus.In the method introduced, know
The following value or parameter of the control signal reach the sensing point of the friction clutch 14 in the case where the value or the parameter,
The following value for knowing control signal, in the case where the value, the friction clutch just transmits a torque.Thus may be used
To export contact point (Kiss-Point).
The clutch of the friction clutch 14 indicates the mutual movement of clutch disc 20, i.e., mutually moves to together or mutually
It moves from.It moves to clutch disc 20 mutually together, transports them mutually
It is dynamic to leave.
Fig. 2 shows a kind of flow charts of possible process of described method.
It is detected in the first step 30 of also referred to as initiating events, if meet rim condition.Rim condition can example
It is in this way:
Clutch is to disconnect,
In the case where considering that subsequent revolving speed improves, motor rotary speed is sufficiently high for adaptation,
Gear has been linked into,
Service brake has operated,
Motor is not lighted a fire,
Furthermore, it is noted that if it would be possible, being switched in other words of being to turn on of ancillary equipment.
If meeting the rim condition, the raising of the revolving speed of motor is carried out in next step 32, until reaching one
Upper rotary speed threshold value.Next start real learning process in next step 34, in this case, revolving speed constantly reduces,
Because motor is braked by its internal moment of friction.Later, the clutch is engaged in step 36, this is referred to as search
(Suchlauf).The trend of monitoring rotation speed in the case.Such as the gradient of revolving speed trend is calculated at regular intervals.
Described search can be limited via a rated value slope (Sollwertrampe) in the case.Furthermore it is suitable for
, the gradient on the rated value slope is related to gear.In addition, the gradient on the rated value slope can be with corresponding traveling
Situation is related, because it is less to require higher adaptation safety to exist in some cases in other words in some specific cases
Time, to execute an adaptation.The rated value slope describes a trend, which can be close to walking for actuator stroke
To and therefore close to the trend of actuator control signals.It to attempt in principle, execute this method as quickly as possible.
Furthermore appropriately, the gradient on the rated value slope and the height of revolving speed rotational speed difference in other words is highly relevant,
That is, motor close to 0 turn per minute, approaches idle running etc..This depends on operating condition.
In addition, the gradient on the rated value slope can change during adaptation procedure, to provide as far as possible accurately
Value, or ensure corresponding comfort level.
If observing the change of the univocality of motor rotary speed in next step 38, that is to say, that motor by strongly or
It says and weaker brakes, be then inferred to, clutch transmits a torque.Via it is existing measurement sample value know univocality sensing point and
Contact point is known when necessary.
Therefore, the method introduced is characterized in that, initiatively causes test mode, in the test mode described in execution
The learning process adaptation in other words.This increases to start to carry out via the revolving speed.
Fig. 3 is shown for illustrating sliding (Segeln) or in the case where putting (Inbetriebsnahme) into operation
Sensing point adaptation signal trend.Here, curve 40 shows desired under the premise of not having sensing point adaptation turn
Speed trend and curve 42 have said the revolving speed trend with sensing point adaptation measured.44 explanation of signal, if at vehicle
In sliding in operation.Another moves towards the gradient that 46 show revolving speed and curve 48 shows the torque transmitted by clutch.
That slides starts with the label of arrow 50, and the starting point of clutch engagement is shown using arrow 52, actuator speed
Reduction utilize 54 explanation of arrow.Sensing point is shown using arrow 56.
Double-head arrow 60 shows following time interval, in the time interval, in the feelings of the clutch reliably disconnected
The gradient of revolving speed can be formed under condition.Double-head arrow 62 shows following time interval, and clutch is delayed in the time interval
Slowly it is closed.Transmitted clutch engagement force is calculated in the difference of calculated gradient from actual revolving speed gradient and on curve 40
Square.
Therefore, the sensing point can be known from curve 42 or from curve 46.
Trend of the clutch torque 80 about the actuator stroke on abscissa 82 is depicted in Fig. 4.It is identifiable
It is that the clutch torque just increases since point 84.It is still 0 by the torque that clutch transmits on point 84.Point 84 is referred to as
Contact point.Second point 86 being labeled indicates an actuator stroke, and can measure since the point can detect a clutch in other words
Device torque.The second point 86 corresponds to the sensing point.
Now in the case where executing this method, change actuator and control size, to be actuated along the change of abscissa 82
Device stroke.This is shown using arrow 88.Revolving speed is recorded during this period and can know at least one gradient, usual certain amount
Revolving speed gradient.Thus it can also determine that a gradient is moved towards.Once the significant changes of gradient have been obtained, when the variation for example becomes
When positive, then it is inferred to, clutch torque is greater than 0, that is to say, that clutch transmits a torque, and therefore reaches the detection
Point.Later, it is possible thereby to know the contact point, which is such point, and the gradient is not shown also just at that point
Significant changes are shown.
The manipulation parameter can be changed continuously or step by step and therefore change actuator stroke.In the case, promote
Dynamic device stroke can be close to a rated value slope.Also it can be stated that actuator stroke is no more than the rated value slope.
