Technical field
The present invention relates to the method and apparatus for controlling internal combustion engine.
Background technology
A kind of method for being used to be connected to drive motor in power train as known to the A1 of DE 10 2,013 215 101,
The speed discrepancy between the input side and outlet side of clutch has been obtained in this method（ndiff）And then by presetting
There is specified clutch torque to be passed to manipulate the clutch according to the speed discrepancy.
The content of the invention
On the other hand, the method for the feature with the present invention（In the method, it can be set in advance when input speed has exceeded
Fixed slides interruption rotating speed（Segelabbruchdrehzahl）When, close the clutch of the automation opened in motor vehicle
Device）Especially had the advantage that when applying in a motor vehicle, i.e. coasting time, that is, clutch is opened and interior therebetween
It the time that combustion engine is cut off or can run with idler revolutions, can be maximized, and traveling dynamic can be kept as simultaneously
It is very high.Retain the intuitively intervention possibility to performances of motor vehicles simultaneously for driver.
Fuel and therefore reduction discharge can be saved by sliding share by maximization.By the quantity for reducing coast period
Clutch abrasion is realized because less frequently reducing closing course.
Because：It can provide in this approach, when recognizing drive pedal and starting, terminate sliding mode, also
Terminate the rolling that motor vehicle is opened with clutch.If then the input speed of clutch is too high, then the bent axle of motor-side

Adjust consistent：So that when performing kickdown when input speed is less than or equal to interaction rotating speed, changing low one grade and following
Input speed raising will not cause exceed slide interruption rotating speed.Therefore avoid coast period due to shift gears without will
Interruption.This point can be avoided to synchronization and intervene internal combustion engine and/or electro-motor and therefore cause further
Saving of fuel.Showed for this, can be preset according to the gear being linked into and slide interruption rotating speed and/or interaction turn
Speed.
In another aspect it can be stated that when input speed drops below maximum (top) speed,（Closure clutch it
Before）The clutch of automation is opened according to the input speed of transmission mechanism.Maximum (top) speed is worthily higher than minimum speed herein,
And/or interrupt rotating speed and/or higher than interaction rotating speed higher than sliding.For example it can relatively select maximum (top) speed with gear.For example
It can so select to slide interruption rotating speed for particular gears all the time so that the maximum of its next more low-grade location of correspondence turns
Speed, can particularly simply reach a kind of performance that can clearly allow driver to predict of motor vehicle by this way.
Herein especially it can be stated that when input speed is again above maximum (top) speed, clutch is also closed again.Therefore
Can prevent in a particularly simple way, the rotating speed of input speed and bent axle after clutch closure synchronously be considered as
Make us uncomfortable.
In another aspect it can be stated that the internal combustion engine of motor vehicle is cut off when clutch is opened.This operation mould
Formula is also referred to as " motor stops-sliding ".
In another aspect it can be stated that the internal combustion engine of motor vehicle when clutch is opened with can be set in advance turn
Speed, particularly run with idler revolutions.This operational mode is also referred to as " dally-slide ".
