Abstract
The invention provides a method for adapting to an automated friction clutch (14). In the method, a course of an engine speed is recorded and evaluated.
Description
Technical field
The present invention relates to a kind of method and a kind of system, a kind of computer equipment and a kind of controller for performing the method for the friction clutch for adaptive automation.
Background technique
Clutch connects the machine element of two axles for rigidly, flexibly, movably or releasably.Utilize the connection that provided by clutch can transmitting torque between the shafts.Can use friction clutch in a motor vehicle, in these Motor Vehicle, when connecting when starting, and when again connecting after gear shift, the rotating speed can covered between two axles by slide (Schlupf) is different.
The friction clutch of automation is handled by means of actuator usually, and it is manipulated by electronic control unit, such as motor controller.The cooperation of clutch and internal-combustion engine is carried out usually in moment aspect, and that is the control gear of higher level requires the moment of the determination of the parts, i.e. clutch and the internal-combustion engine that participate in, in order to guarantee to travel the best of running and comfortable process.Interface for manipulating clutch actuator forms detailed clutch model at this.Its task is, under all given boundary conditionss, such as temperature, rotating speed, wearing and tearing etc., always produce each correct rating value for clutch actuator, thus clutch sets out desired rated moment.
Usual clutch indicatrix forms the basis of clutch model, and that is attaching troops to a unit of actuator controling parameter, such as, disc spring tongue position when traditional dry friction clutch or the manipulation pressure when traditional wet friction clutch and the moment transmitted occur.But this indicatrix is not static.Major advantage for indicatrix correction defines so-called adaptation and mates in other words.At this, utilize head office that the parameter of model is carried out to Credence test and corrected if desired at run duration.
An important parameter is such as so-called sensing point (Tastpunkt).Its point be expressed as follows, transmits a torque from this point.From this sensing point, point of zero moment, so-called point of contact can be known, the clutch just also non-transmitting torque when this point.Now, when determining described sensing point, determine the manipulation parameter of actuator, when described sensing point is present in this manipulation parameter.Described point of contact can be known thus.Therefore the manipulation parameter for actuator has been drawn, in the case, just also not by clutch carry-over moment.
A kind of method of the friction clutch for adaptive automation is there is known from publication DE 10 2,013 208 256 A1, it is handled by means of an actuator manipulated by controller, wherein, perform a learning process, determine that one for manipulating the value of actuator in the case, this value represents the sensing point of friction clutch.In the case, clutch on-off is made when the learning process of frictional connectors, the trend of recording pen motor rotating speed, therefrom calculates at least one gradient and at least one gradient this calculated is evaluated, in order to determine the value of the feature representing sensing point.
The method described in this publication relates to and normal travels the natural travel situations run, may in conjunction with slide (Segeln) in other words start/stop slide, being in motion to make vehicle needs this to slide.
When first time puts clutch into operation, in other words between vehicle installation car or under service scenario, usually (zugegriffen) naturally travel situations is not taked, because one cause the vehicle operating of this travel situations due to putting into operation of mistake also unfeasible, or because vehicle cannot correspondingly move due to the specified criteria at scene.
The utilization that the motor during stationary vehicle mentioned in this publication slows down is actually difficulty, because can be used for the adaptive time when the racing speed of 500 to 800U/min is short especially, until it is static to reach motor.
Summary of the invention
Within this context, a kind of method according to claim 1 and a kind of system according to claim 11 is introduced.Mode of execution obtains by dependent claims and this specification.
Therefore, in introduced method, apply by friction clutch (eindeutig) change that an adaptive moment observes the univocality of motor rotary speed.In the case, in the enforcement of motor, friction clutch can be made to brake strongly or weaker according to the difference of load.Described load carrys out detecting and assessing for the effect of motor rotary speed by the tracking of rotating speed.
The clutch (R ü cken) of friction clutch means, the clutch plate of clutch moves to together mutually or motion is left mutually.The joint (Einr ü cken) of friction clutch is interpreted as gradually closed of the clutch disconnected at the beginning, and in the case, clutch has different engagement positios.Therefore, described friction clutch is purposively engaged, during this period, controller obtains a signal, is motor rotary speed in this case, calculates at least one gradient if desired and evaluate this gradient from the trend of the value for rotating speed, in order to determine, whether reach sensing point.Utilize disengaging (Ausr ü cken) to be described below process, when this process, clutch plate is mutually moved and is left, and therefore clutch is disconnected.Therefore, utilize concept clutch to represent in this and engage or depart from.
Therefore when static vehicle, such as in driving belt end or under service scenario, putting into operation for the first time of clutch system is feasible.At this, " artificially " causes the corresponding edge condition promoted in other words for adaptation.
Describe a kind of method, in the method, different from described in publication DE 10 2,013 208 256 A1, not utilize until the motor decelerating phase (Motorauslaufphase) of motor stopping, but utilize from rotary speed threshold value on until the speed range of the intervention of motor idle running adjustment.This speed range is purposively set by described method and for adaptation.
Therefore, supplement the known method that an adaptation is set in motor slows down, thus this adaptation provides the more time and therefore can carry out effective adaptation.
It should be noted that, in order to the adaptation more than racing speed can be realized, make when the internal-combustion engine operated via diagnostic test device or via storage program in the controller, be similar to one scan scan test (Abtast-bzw. Scantest) in other words, be raised in order in the upper rpm level needed for sensing point adaptation.If reach above-mentioned situation, then terminate rotating speed by a corresponding exerciser order and improve, internal-combustion engine to be placed in inertia traveling (Schubbetrieb) and to start aptamer sequence (Adaptionssequenz).Rotating speed improve start before and/or should test before aptamer sequence starts, observe the boundary conditions for performing sensing point adaptation, such as clutch disconnects, internal-combustion engine rotational speed is enough high for adaptive, gear is linked into, and service brake (Betriebsbremse) has handled and motor is not lighted a fire.
In one embodiment, this flow process its be pushed (angesto en) once after full automation ground implement and also can repeat in multiple times if desired, such as, in order to check the confidence level of adaptive result.
In a kind of mode of execution of alternative, if do not wished the raising of the automation of motor rotary speed by diagnostic test device, then improve motor rotary speed by gas pedal.This can perhaps be guided by the information of diagnostic test device one side or also can be implemented by the prompting of the display device on vehicle.
Method described here is responsible for, the state of not lighting a fire that the motor stopped for the motor that having subsequently slows down from one improve be suitable for import adaptive racing speed.The time that can be used for adaptation grows more than twice than the situation under in general common rotating speed in this case, thus significantly improves adaptive soundness.
The required rpm level for improving draws the specific and specific parameter of travel situations from different vehicles, such as:
1. the rotating speed gradient of motor deceleration, interior friction, supplementary equipment
The high load of high gradient, that is high friction supplementary equipment in other words, requires higher rpm level, adaptation duration can be made thus to remain unchanged.
2. the clutch system of automation friction clutch in other words is dynamic, that is must can provide an adaptive moment between motor deceleration period
In the very little dynamic situation of clutch system, need the more time, in order to provide detection moment in other words for when conversely, from provided detection moment, disconnect power assembly system.The more time for adjustment process is eliminated in an adaptation duration improved, and this must be compensated by higher rpm level.
3. reliably must recognize the time resolution (Aufl sung) of Rotating speed measring, that is change, such as, via the filtration of multiple measured value
When the very little time resolution of rotating speed measured value, extend and measure interval, can reliably detect and evaluate rotation speed change.The measurement interval of prolongation needs the adaptation duration of prolongation and the rpm level of therefore same needs raising.
In another embodiment, rotating speed is brought up on a fixing high rotating speed, such as, bring up on motor maximum (top) speed.In another embodiment, only bring up to for reliably identifying required rpm level.
Other advantage of the present invention and design proposal provide from specification and accompanying drawing.
In one aspect of the method, the present invention relates to a kind of computer program, its setting is for implementing the institute of said method in steps.
In one aspect of the method, the present invention relates to a kind of machine-readable storage medium, this storage medium stores this computer program.
In one aspect of the method, the present invention relates to a kind of controller (24), its setting is for implementing the institute of said method in steps.

Embodiment
The present invention schematically illustrates by mode of execution in the accompanying drawings and describes in detail when reference accompanying drawing subsequently.
Fig. 1 shows the power assembly system of Motor Vehicle, and it utilizes reference character 10 to represent.The diagram illustrate internal-combustion engine 12, friction clutch 14, speed changer 16 and a driven wheel 18.Therefore, friction clutch 14 is utilized to interrupt and closed described power assembly system 10.This is by the clutch of friction clutch 14, namely engages or depart to carry out.At this, the clutch plate 20 of friction clutch 14 moves to together mutually or motion is left mutually.Use an actuator 22, it is manipulated by a controller 24, such as motor controller again for this reason.Use a manipulation signal for this reason.In introduced method, know following value or the parameter of this manipulation signal, when this value or this parameter, reach the sensing point of described friction clutch 14, namely know the following value of manipulation signal, when this value, described friction clutch just transmits a moment.Also point of contact (Kiss-Point) can be derived thus.
The clutch of described friction clutch 14 represents the mutual motion of clutch plate 20, namely mutually moves to together or mutually move to leave.When engaging, clutch plate 20 being moved to together mutually, making them mutually move when departing from and leaving.
Fig. 2 shows the flow chart of a kind of possible process of described method.
Detect in the first step 30 being also referred to as initiating events, whether meet edge condition.Edge condition can such as:
-clutch disconnects,
-when considering that rotating speed subsequently improves, motor rotary speed is sufficiently high for adaptive,
-gear is linked into,
-service brake operates,
-motor is not lighted a fire,
Furthermore, it is noted that if possible, supplementary equipment is being switched in other words of connection.
If meet described edge condition, then in next step 32, carry out the raising of the rotating speed of motor, until reach rotary speed threshold value on.Next in next step 34, start real steering procedure, in this case, reduce rotating speed constantly, because motor is braked by the friction torque of its inside.Afterwards, engage described clutch in step 36, this is referred to as search running (Suchlauf).The trend of monitoring rotation speed in the case.The gradient of rotating speed trend is such as calculated with the time lag of rule.
Described search running can be limited in the case via a rating value slope (Sollwertrampe).In addition desirably, the gradient on described rating value slope is relevant to gear.In addition, the gradient on described rating value slope can be relevant to corresponding travel situations, because require that higher adaptive Security exists the less time in other words in some cases in some specific cases, adaptive in order to perform one.Described rating value slope describes a trend, and this trend can close to the trend of actuator stroke and therefore close to the trend of actuator control signals.To attempt in principle, perform the method as quickly as possible.
In addition desirably, the height correlation of the gradient on described rating value slope and the height of rotating speed speed discrepancy in other words, that is, motor close to 0 turn per minute, close to idle running etc.This depends on runnability.
In addition, the gradient on described rating value slope can change during adaptation procedure, is worth as far as possible accurately in order to provide, or guarantees corresponding comfort level.
If observe the change of the univocality of motor rotary speed in next step 38, that is motor is weaker braked strongly in other words, then infer, clutch transmits a moment.Know the sensing point of univocality via the measurement sample value existed and know point of contact if desired.
Therefore, the feature of the method introduced is, causes test mode on one's own initiative, performs described steering procedure described adaptation in other words in this test mode.This raises via described rotating speed and starts to carry out.
Fig. 3 shows for illustration of sliding the signal trend of (Segeln) or the sensing point adaptation when putting (Inbetriebsnahme) into operation.At this, curve 40 shows rotating speed trend desired under the prerequisite without sensing point adaptation and curve 42 has said the rotating speed trend with sensing point adaptation measured.Signal 44 illustrates, whether vehicle is in is slided in operation.Another moves towards 46 and shows the gradient of rotating speed and curve 48 shows the torque of being transmitted by clutch.
Starting of sliding utilizes arrow 50 to mark, and the starting point that clutch engages utilizes arrow 52 to illustrate, the reduction of actuator speed utilizes arrow 54 to illustrate.Sensing point utilizes arrow 56 to illustrate.
Double-head arrow 60 shows following time interval, in this time interval, can form the gradient of rotating speed when the clutch reliably disconnected.Double-head arrow 62 shows following time interval, and in this time interval, clutch is closed lentamente.Transmitted clutch torque is calculated from the rotating speed gradient of reality and the difference of gradient that calculates at curve 40.
Therefore, described sensing point can be known from curve 42 or from curve 46.
Depict the trend of clutch torque 80 about the actuator stroke on abscissa 82 in the diagram.Discernible, from point 84, described clutch torque just raises.On point 84, the moment transmitted by clutch is still 0.Point 84 is referred to as point of contact.Second is represented an actuator stroke by the point 86 marked, and can measure and can detect a clutch torque in other words from this point.This second point 86 is corresponding to described sensing point.
Now when performing the method, changing actuator and controlling size, thus changing actuator stroke along abscissa 82.This utilizes arrow 88 to illustrate.Record rotating speed during this period and at least one gradient can be known, the rotating speed gradient of usual some.Also a gradient trend can be determined thus.Once draw the notable change of gradient, when this change case is as become positive, then infer, clutch torque has been greater than 0, and that is clutch transmits a moment, and therefore reaches described sensing point.Afterwards, can know described point of contact thus, this point of contact is such point, and described gradient does not just also demonstrate notable change at that point.
Can described manipulation parameter be changed continuously or step by step and therefore change actuator stroke.In the case, actuator stroke can close to a rating value slope.Also can specify, actuator stroke is no more than this rating value slope.
