Specific implementation mode
Fig. 1 shows vehicle 1, which has engine 2, clutch 3 and speed changer 8.The input shaft of vehicle 1 is usually logical
It crosses clutch 3 and speed changer 8 connects engine 2 and the driving wheel of vehicle.The different of these elements of power train are opened up
Flutter is to be described in detail well known to technical staff and no longer.Fig. 1 is further it is shown that a clutch pedal 4, Ke Yiyong
It opens clutch 3.Do not require forcibly herein by this be used for open clutch 3 operating element 4 be configured to from
Clutch pedal.It is for instance also possible that when the gear lever of the block selecting for speed changer 8 is actuated, driven then just having recognized
The clutch wish for the person of sailing.A pedal travel sensor 5 can be set thus, and the position of clutch pedal 4 is reported to control
Device 6, controller facilitates the corresponding position of clutch 3 by an actuator, as illustrated in fig. 2.In addition it also sets up
Environmental sensor 7 provides the feedback of the ambient enviroment about vehicle 1 to controller 6.Environmental sensor 7 may, for example, be
Radar sensor, or another sensor, as it is to be adjusted well known to the adaptability speed adjustment equipment of function with spacing
As.In addition, vehicle 1 has several brakes（It is not shown）, these brakes can be actuated by driver, but they also can
It is actuated by other brake control systems, such as ESP, especially when controller 6 has the information that must reduce speed.
A kind of power train of feasible form of implementation by the present invention is shown in further detail in Fig. 2.Internal combustion engine 2 by from
Clutch 3 and speed changer 8 are connect with wheel 11.Clutch controller 70 controls actuator 9, and actuator can open and close clutch
Device 3.The position of clutch pedal 4 is forwarded to clutch controller 70 by pedal travel sensor 5.
Fig. 3 shows a kind of possible information flow of form of implementation by the present invention.
The form of implementation shown in Fig. 4 to 6 of method is for example run on controller 50, which can correspond to control
Device 6 processed.Such as can be run on controller 6, but the ACC functions 55 that can also be carried out on individual controller, it borrows
It helps environmental sensor 7 and is pass on to the normal speed of controller 50 to execute ambient enviroment detection and find out one.ACC this
A function is not a part in the present inventive method.Controller 50 can call output device, such as display control unit
60, it can be with trigger scope 61, so as to driver's relay information with it.
Controller 50 can trigger clutch 3 by clutch controller 70 in addition.This point can be for example such as Fig. 2
It is shown to be occurred like that by triggering actuator 9.Herein also it is possible that clutch controller 70 is integrated in controller 50
In.
Controller 50 can trigger engine 2 by engine control system 80 in addition.Herein also it is possible that starting
Machine control device 80 is integrated in the controller 50.
Controller 50 can trigger the brake of vehicle 1 by brake control system 90, such as ESP control devices in addition
12。
Fig. 4 shows a kind of form of implementation in the present inventive method.Step 100 and 110 is not forcibly by this
A part for the method for invention.In step 100, ACC executes ambient enviroment detection, and thus finds out vehicle in step 110
1 normal speed.It can be related to a kind of instantaneous normal speed herein, or be related to a kind of Deuteronomic normal speed.Then
It is step 120, examines whether normal speed is zero or is zero quickly in this step.If so, so carrying out step 140.If no
It is, then selectively carrying out step 130.It can examine in step 130, if face engine 2 and stop working risk.This point
For example can thus it occur, that is, ACC 55 passs on one to controller 50 and is less than actual speed（The actual speed is in controller 50
In it is known）Normal speed.Attempt to make actual speed and specified speed by engine control system 80 or arrester control device
Degree matches.In the gear of speed changer 8 being currently linked into, this point may result in, and engine is under incorrect gear
It is flame-out.Such as can examine in step 130, whether the rotating speed of engine 2 has decreased to can be under scheduled threshold value, wherein
When rotating speed drops to can be under scheduled rotating speed when just determination face flame-out risk.If facing this flame-out risk, then into
Row step 140.But occur in step 130 inquiry, that is, if rotating speed not less than can scheduled threshold value, then carrying out step
110。
Instruction is pass on to clutch controller 70, that is, open clutch 3 in step 140.Clutch controller 70 is then
Actuator 9 is triggered in this way so that clutch 3 is opened.Then carry out step 150.
A specified gear is found out in step 150, can be linked by driver.Specified gear is for example found out in this way,
I.e., it is possible to realize the decline of the normal speed of vehicle 1 in the case where engine 2 is not flame-out.Specified gear can also be by this way
It finds out, that is, next vehicle launch particularly can be cosily executed when vehicle 1 stops, or also in the vehicle of traveling
A kind of acceleration to match can be reached.Selectively an instruction is pass on to display control apparatus 60, that is, in display 61
The upper specified gear of output.
Step 160 is then carried out, is examined in this step, whether the actual gear being actually linked into corresponds to specified gear.
Actual gear can for example be found out by the sensor on the shift connecting rod of gear lever herein.If it is not, this is to say, hanging
Entered mistake gear or be linked into gear not yet, then carry out step 150, that is, or clutch 3 holding be opened.If anti-
Actual gear be equal to specified gear, then carry out step 170.It finds out, the wish of driver, that is, is closed in step 170
Clutch, if be determined.This may, for example, be a part for the method run in the controller 50.If recognizing, driver
With the wish for being closed clutch, then clutch 3 is closed in step 180.Otherwise for example by branching back to step
150 keep the clutch 3 to be opened.
Another form of implementation is illustrated in Figure 5.Here, step 190 is branched into after step 140, in step
It is examined in 190, whether ACC 55 has found out, and ambient environmental conditions make vehicle 1 be accelerated as or becoming necessary.Such as it can
To examine, whether normal speed is higher than starting threshold value.Starting threshold value can for example be selected according to actual speed herein.If
It is, then then carrying out step 180, clutch 3 to be closed in step 180, otherwise branches back to step 190.
Thus the form of implementation of Figure 4 and 5 is it is of course possible to being for example combined, that is, when specified gear does not correspond to actual gear,
Even if this clutch is kept to open if when facilitating clutch 3 to close by ACC 55.
Another form of implementation of the present invention is illustrated in figure 6.ACC 55 is found out again through ambient enviroment detection 100
Normal speed 110, normal speed are pass on to controller 50.The actual gear being actually linked into is found out in step 200.This
A little can for example it be found out by the sensor on the shift connecting rod of gear lever.Step 210 is then carried out, in step 210
It is found out for the actual gear being currently linked into maximum reachable in the frame of the permitted rotating speed that can be adjusted of engine 2
Maximum speed or the minimum speed of minimum requirements.In the step 220 that can selectively cancel, when only finding out minimum speed
When, then examining whether maximum speed is less than normal speed.In this case, normal speed is arranged in step 230
It is identical with maximum speed.It, can be in step 240 alternatively or in addition to step 220 when finding out minimum speed in step 210
Whether outer inspection, minimum speed are more than normal speed.If so, so normal speed is configured to and minimum speed in step 250
It spends identical.When the shift process of driver is not that corresponding specified gear is performed, in this way can for example ACC's plus
It is reacted to that in a simple manner during speed.
Alternately or supplement, can also in the case of vehicle deceleration, that is, in the case where actual speed is slack-off,
Clutch 3 is opened in step 250, and bears the delay of brake 12.This have the advantage that reduction follows closely in front
The risk of the vehicle traveling of traveling.When driver has been linked into correct gear, then acceleration is realized, or by corresponding
Ground, which triggers engine 3 and realizes, to slow down.
