Outside also in subsequent explanation and in attached drawing, wherein the feature can not only be individually critically important for the purpose of the present invention, and
And also can be critically important for the purpose of the present invention with different combinations, and this is no longer explained in detail.
The present invention has the following advantages, i.e., automatic at least semi-automatic part in other words（teilautomatisiert）
The clutch pedal for needing manually handle can be also set in speed changer, and which improve the acceptabilities of vehicle.Here, starting
When motor vehicle with such at least automanual speed changer and clutch pedal, it is flame-out to be reliably prevented internal combustion engine.This
More particularly to there is clutch torque to be passed（" clutch rated moment "）The case where with mutation, such case is for example being driven
The person of sailing let the clutch be slipped " suddenly " pedal when occur.The intervention according to this method can be so realized in many cases so that
Driver never perceives this situation.In addition, The invention also achieves especially often start and repeat parked
Clutch pedal manipulation need not be carried out in the case of congested traffic.It according to the method for the present invention can be integrated with less cost
Into the existing system for controlled clutch device.
The present invention relates to a kind of method for running motor vehicle, the motor vehicle includes internal combustion engine, at least automanual
The clutch apparatus of speed changer and the connection internal combustion engine and at least automanual speed changer.It is described according to the present invention
Clutch apparatus is according to characterization clutch pedal position（Orientation）Parameter, especially clutch rated moment and according to characterization institute
The operation parameters for stating motor vehicle and/or the operating status of the internal combustion engine and/or the automatic transmission are manipulated.
It is thus achieved that manually the clutch apparatus can not only be manipulated by means of clutch pedal and can oneself
The clutch apparatus is manipulated dynamicly.For this purpose, single either multiple parameters or operation parameters can be used.Namely according to this
The method of invention realizes corresponding " most preferably " manipulation realized according to the parameter or operation parameters to clutch apparatus.
This, the driver of motor vehicle can manually start motor vehicle, and wherein driver has the feeling for manipulating manually speed changer.So
And it is it is not flame-out or only seldom flame-out by realizing internal combustion engine according to the method for the present invention." people's " starting can be imitated herein
Behavior, to which driver does not feel as the intervention according to this method substantially in many cases.This feeling is will produce, i.e.,
Motor vehicle is it may be said that leniently and without flame-out jeopardously start.According to the present invention, clutch pedal be not applied directly to from
On clutch device, but for example the position of clutch pedal is acquired by means of potentiometer or similar device and delivered this to
It is capable of the regulating device of controlled clutch device.
The design of the method proposes, the gradient of clutch rated moment is acquired based on the clutch rated moment acquired,
And the current maximum allowable gradient of clutch rated moment is acquired from multiple current operation parameters, and clutch apparatus
Manipulation depending on clutch rated moment obtained gradient and maximum allowable gradient relationship.From driving experience
It is generally known that when driver " decontrols " clutch pedal too quickly, internal combustion engine may require that excessively high torque, wherein internal combustion sometimes
Chance " flame-out ".According to the present invention, such as by continuing to acquire clutch to the derivation about the time of clutch pedal position
The gradient of rated moment.Equally from multiple current operation parameters（Such as current rotating speed, the gear being currently placed in, gas pedal
Position etc.）Acquire the current maximum allowable gradient of clutch rated moment.The maximum allowable gradient is so acquired, i.e., not
It is expected that internal combustion engine " flame-out ".Here, the manipulation to clutch apparatus realized by means of actuator is according to clutch rated moment
Obtained gradient and maximum allowable gradient relationship carry out.Thus, it is possible to by clutch pedal by vehicle driver
The manipulation of progress be compared with internal combustion engine, the current operating conditions of automatic transmission and/or other parameters and when necessary into
Row is corrected." most preferably " manipulating for clutch apparatus, wherein vehicle driver's one side can be realized in this way substantially
There is " the clutch feeling " corresponding to manual transmission, however on the other hand internal combustion engine can be prevented flame-out according to the present invention.
Another design scheme of this method proposes, when the obtained gradient of clutch rated moment is more than maximum allowable
Activate regulating device when gradient, the regulating device applies modified clutch rated moment, the clutch rated moment with
Maximum allowable gradient is closed clutch apparatus（" clutch "）.Pass through continuing in internal combustion engine operation for clutch rated moment
The comparison of the gradient acquired and maximum allowable gradient can determine, if there are flame-out danger.If obtained gradient
More than maximum allowable gradient, then according to invention activation regulating device.This is using its existing parameter or operation ginseng
Modified clutch rated moment is acquired in the case of amount.It is preferred that modified clutch rated moment is so measured, so as to
It is closed clutch with maximum allowable gradient.Thus on the one hand internal combustion engine can be prevented flame-out, and on the other hand can with
The clutch torque of maximum possible realizes the starting or acceleration of motor vehicle under the conditions of relevant work.Driver has such sense
Feel, i.e., clutch apparatus essentially according to it, manually react by primary action, while realizing corresponding maximum quick
Dynamic or acceleration.
Another other design schemes of this method propose, when not being placed in neutral gear, brake activation device and car speed
When less than limiting value, activate the regulating device with cut-off clutch.Be thus described according to the method for the present invention another has
Purposes.That is in this way can in the braking process of motor vehicle, when vehicle had it is relatively small
Car speed and correspondingly internal combustion engine prevent internal combustion engine flame-out when having corresponding low rotating speed, it is assumed for example that vehicle drive
Member forgets controlled clutch pedal or manipulates too late.
It is preferred that the regulating device obtains the parameter of input parameter or the characterization input parameter below at least：Vehicle
Speed, accelerator pedal position, the actual torque of internal combustion engine, the clutch rated moment that is acquired by the position of clutch pedal.Also
It can addedly use the gear of semi-automatic transmission being accordingly placed in as the input parameter of regulating device.By means of described defeated
The best manipulation of clutch apparatus can be realized by entering parameter, and flame-out danger may be not present.
Another design scheme of this method proposes, when the clutch rated moment acquired from clutch pedal position is small
When the modified clutch rated moment sent out by regulating device, the regulating device is deactivated.In this case
For do not need the intervention of regulating device so that the manipulation of clutch apparatus substantially corresponds to the behaviour of clutch pedal
It is vertical so that vehicle driver can in a manner of being accustomed to for it controlled clutch device.

The position of gas pedal；
The position of clutch pedal；
The gradient of the position of clutch pedal；And/or
The maximum allowable gradient acquired by operating status.
It is thus described the important parameter of the operation of characterization internal combustion engine, motor vehicle and clutch apparatus, the parameter
It is meaningful or possible significant for being transmitted by the torque of clutch apparatus.Here, need not use all
Parameter described here for running the method.However the operation parameters for regulating device are more, according to this hair
The effect of bright method is usually better.Certainly, for the operating parameter that provides also always it will be appreciated that for described in other characterizations
The parameter of operation parameters.
It is logical according to the position of the operation parameters and/or clutch pedal according to the method for the present invention for can be with overview
At least one first state and the second state representation are crossed, the characterization clutch is stepped on wherein deactivating in said first condition
The amendment of the parameter of Board position or amendment to the clutch rated moment, and activated in said second condition to institute
State the amendment of the parameter of characterization clutch pedal position or the amendment to the clutch rated moment.Here, described first
State corresponds to deactivated regulating device, and the second state is corresponding to the regulating device of activation.Thus for motor vehicle
Show that can clutch in most cases be manually operated as custom in following advantages, i.e. driver for driver.Only
Only when regulating device is got involved according to other standards described above in the manipulation of clutch apparatus, driver just can determine that
The behavior different from manually handle clutch.It can also will be kept as to the greatest extent with the difference of purely manual manipulation according to the method for the present invention
It may be small.Thus, it is possible to improve acceptability of the driver for the process of regulating device.
It can addedly be proposed according to this method, when the rotating speed of internal combustion engine is less than threshold value and non-controlled clutch pedal
When, then disconnect the clutch apparatus.Thus according to the present invention method also can in internal combustion engine or semi-automatic transmission or
Intervened under other operating statuses of person's motor vehicle, other described operating statuses can be substantially independent of brake pedal and/or from
The manipulation of clutch pedal is flame-out suitable for internal combustion engine.It can just be prevented by the intervention of regulating device this flame-out.
