Abstract
The invention relates to a method and a device for operating a motor vehicle with an internal combustion engine in a coasting operating mode in which the motor vehicle rolls essentially in a propulsionless fashion and essentially without a perceptible engine drag torque on an essentially level road if there is no propulsion request or braking request from a driver of the motor vehicle. According to the invention, the coasting operating mode is not brought about by automatically opening the drivetrain but rather is simulated with the clutch closed in that so much air/fuel mixture is fed to the internal combustion engine that the engine drag torque is largely but not completely compensated.
Description
Technical field
The present invention relates to a kind of method and device that under the taxi operation pattern, operates the motor vehicle with internal-combustion engine, wherein, if the driver of motor vehicle does not advance demand or braking requirement, the motor vehicle engine resistance torque to slip car and not perceive in fact without the mode that advances in fact on the road of level substantially then.
Background technique
Such method and device are disclosed by patent documentation DE10 2,008 029 453 A1.
If the driver removes his pin from gas pedal, because engine resistance torque, traditional motor vehicle with internal-combustion engine can become more and more slower.Only in relatively large negative slope situation, engine resistance torque just is not enough to reduce the speed of vehicle.This also depends on speed that weight, the vehicle of vehicle is current and the shelves speed of current engagement.
In the motor vehicle with internal-combustion engine and automatic transmission, there is so-called taxi operation pattern, wherein, when driver's pin leaves gas pedal, generally automatically open transmission system by automatically opening clutch.During the idling, also can under the taxi operation pattern, close internal-combustion engine fully, for example, in the situation that the automatic starting/stopping device.Under the taxi operation pattern, can eliminate engine resistance torque in order to save fuel oil.
Driver's various interactions, such as, activate brake petal, activate gas pedal or activate the fast selective lever of shelves and cause that transmission system closes, that is to say, the taxi operation pattern is finished and cause the conventional truck behavior.Use this generic logic, the driver can control and activate and/or close taxi operation pattern and he and can slip in taxi operation pattern and the tradition with engine resistance torque and select between the car.
The taxi operation pattern is so that capable of saving fuel oil becomes possibility, because compare the Motor Vehicle with manual clutch that is subject to the engine resistance torque impact, substantially motor vehicle can be to slip fartherly without the mode that advances on the road of level, especially consider a kind of like this fact: if be not to remain on the idling level without advancing the demand stage fuel delivery, but close (excess fuel cut-out) fully, then engine resistance torque can become larger.In addition, the taxi operation pattern is to a kind of like this driving experience of driver: encourage him to adopt more conservative drive manner, this is conducive to save fuel oil.
Summary of the invention
The object of the invention is to make motor vehicle, especially the advantage that the motor vehicle that have automatic transmission and a manual clutch are benefited from the taxi operation pattern becomes possibility, even transmission system can not be opened automatically, but also be applicable to have the motor vehicle of automatic transmission, wherein, have the taxi operation pattern of automatically opening transmission system or do not provide or cannot, because in having the automatic transmission of torque converter, not having can be by this situation of the clutch of automatic activation.
Be achieved through the following technical solutions above-mentioned target.
The present invention proposes a kind of method that under the taxi operation pattern, operates the motor vehicle with internal-combustion engine, wherein, if the driver of motor vehicle does not advance demand or braking requirement, motor vehicle with in fact without the mode that advances and substantially on the road of level in fact without the engine resistance torque slide car that perceives, the taxi operation pattern does not cause by automatically opening transmission system, but simulate by closing clutch, wherein a large amount of air/fuel mixture IC engine supplies is so that engine resistance torque is most of rather than fully compensated.
Further, in the motor vehicle with transmission system that can manual unlocking, implement described method, especially in the motor vehicle with manual transmission and manual clutch, implement described method.
Further, only when rotational speed is higher than idle speed and be lower than the maximum rotative speed threshold value, begin to simulate the taxi operation pattern.
Further, when withdrawing from the rotational velocity range of appointment, end simulation taxi operation pattern.
Further, surpass the rotational speed threshold value, then do not start or end simulation taxi operation pattern, this rotational speed threshold value is roughly corresponding to an engine speed, surpass this engine speed, shelves speed changes display unit and shows or indicate the driver should change to more high-grade speed to the driver in the motor vehicle.
Further, in having the motor vehicle of automatic transmission, implement described method, wherein, do not provide to have the taxi operation pattern of automatically opening transmission system.
Further, if the driver does not advance demand or braking requirement then end simulation taxi operation pattern.
Further, if the negative slope that road has is higher than the negative slope threshold value, end simulation taxi operation pattern then.
Further, if finish the taxi operation pattern, then activate the excess fuel shut-off means.
Further, engine resistance torque is all moment of torsion sum, especially generators that needed by oil-engine driven equipment and/or the air-conditioning compressor of vehicle in present engine friction torque and the motor vehicle.
The invention allows for a kind of device that has internal combustion engine motor vehicle for operation under the taxi operation pattern, described equipment is arranged to carry out method described above.
According to the present invention, with the clutch of closing simulation taxi operation pattern, wherein a large amount of fuel/air mixture IC engine supplies so that engine resistance torque by to a great extent but non-full remuneration.Like this, in fact the driver has identical driving experience under the taxi operation pattern of the motor vehicle with automatic transmission and need not to open clutch.
According to the present invention, engine resistance torque is not eliminated fully and only is most of the elimination, and for example 80%.This has 2 benefits: at first, this can prevent the click of the speed changer that may occur, secondly, do not exist in this way in the situation that do not have the driver to have a mind to or notice the substantially risk of accelerating Motor Vehicle coast period on the road of level of this point.
If have and to be implemented method of the present invention by the motor vehicle of the transmission system of manual unlocking, especially on the motor vehicle with manual transmission and manual clutch, be limited in certain rotational velocity range simulation taxi operation pattern optimum selection, its lower limit and idle speed are roughly the same or slightly high, the rotational speed that upper limit correspondence is relatively high.The driver can use wittingly near the engine speed of idle speed and slowly drive being used for, the driver needs propelling force to a certain degree during this period, and the driver can come more slowly to drive vehicle with higher engine speed or avoid at least using engine resistance torque to make to drive too fast wittingly, for example, on sloping road.If withdraw from the rotational velocity range of appointment, then should end simulation taxi operation pattern.
Surpass the rotational speed threshold value, then do not start or end simulation taxi operation pattern, motor vehicle bear whole engine resistance torques like this, therefore preferred rotational speed threshold value is approximately corresponding to engine speed, surpassed engine speed, shelves speed changes display unit and shows to the driver in the motor vehicle, if or do not have this indication, will indicate the driver should gear shift to more high-grade speed.Therefore, generally engine resistance torque comes into force when the driver has expectation to it, and when needs it the time can use it selectively.
In situation of the present invention, owing to not opening clutch, and be limited in the rotational velocity range of appointment simulation taxi operation pattern optimum selection, so at the motor vehicle with manual transmission rather than have in the motor vehicle of automatic clutch, when clutch when closing at last coast period, no matter do not engage the risk of unsuitable shelves speed, be because motor vehicle become slower or the driver forwards another grade speed to.In the motor vehicle with automatic transmission and automatic clutch, this problem relies on the following fact and can avoid: namely, during coast period, shelves speed changes in the mode that is suitable for this speed.
The present invention is not limited to have the motor vehicle of manual transmission and manual clutch, on the contrary, the present invention also is suitable for having the motor vehicle of automatic transmission, wherein, does not provide or can not provide for any reason to have the taxi operation pattern of automatically opening transmission system.In this case, need not to intend in the molding of the upward direction upper limit rotational velocity range of taxi operation pattern, because during coast period, also can automatically adopt the shelves speed of speed changer.Yet, if the driver is arranged on L(lowest gear speed with the driving model selector) or M(manual), the taxi operation pattern that then prevents from having in the motor vehicle of automatic transmission is fit to, because in this case, the driver may want to use whole engine resistance torques, such as when descending is advanced.
If the driver has propelling demand or braking requirement, for example, can be owing to the following fact: the driver have activated gas pedal or brake petal, preferably end simulation taxi operation pattern.When even the negative slope that has when the road surface is higher than the negative slope threshold value, also best end simulation taxi operation pattern can be determined the negative slope threshold value in several ways.When the taxi operation pattern finishes, also can activate excess fuel and cut off (overrun fuel cutoff), that is to say, in order to obtain the maximum engine resisting moment, close fuel delivery fully.
Especially, engine resistance torque be in present engine friction torque and the motor vehicle all moment of torsion sum, especially generators that needed by oil-engine driven equipment and-if any-air-conditioning compressor of vehicle.
The invention provides almost whole benefits that tradition slides, clutch is opened and the not loss on the clutch that for example electricity activates and the risk of joint mistake shelves speed, because the method according to this invention, transmission system is not opened.Yet, if the driver engages wrong shelves speed, as broad as long with conventional ADS driving so, because the driver has noticed this point very soon, and be not after the relatively long time, such as when the motor vehicle with manual transmission and electric driving clutch slide, like this situation may be exactly.
Description of drawings
With reference to the accompanying drawings, exemplary embodiment will provide below, wherein:
Fig. 1 has shown the flow chart of the control strategy when simulating the taxi operation pattern of the motor vehicle with internal-combustion engine,
Fig. 2 has shown the graph of a relation of engine friction conduct to the rotational speed function of gasoline and diesel engine.
Embodiment
Fig. 1 has shown the control route that repeats in a kind of electronic engine control unit of the motor vehicle having internal-combustion engine, foot accelerator clutch and manually shifted transmission.As long as motor vehicle are activated, with regard to initialization route (step S1).As long as execution path, the setting (step S2) of just reading present engine speed and current throttle pedal and brake petal by suitable sensor, and check that whether certain is set is slided and forbid identifying (step S3, S4) in the electronic engine control unit.Forbid sign if arrange to slide, then route turns back to step S2.
Exist multiple the condition that identifies of forbidding that slides to be set, for example, if necessarily formerly having the throttle of burst to move in the time phase, perhaps current certain part that is traveling in the sloping road of tool.In having the motor vehicle of automatic transmission, if the driver has selected L or M driving model, then also can arrange to slide and forbid sign.
Whether do not forbid sign if arrange to slide, then basically allow to slide and detect following two conditions at step S5 and satisfy: engine speed N is lower than threshold value Nmax and gas pedal and brake petal and is not depressed.If whether the testing result of step S5, then route is turned back to step S2.If the testing result of step S5 is yes, then starts vacation at step S6 and slide.
A kind of operator scheme that is interpreted as Motor Vehicle is slided in vacation, in this pattern, clutch cuts out, do not discover in fact on the road of motor vehicle under without the mode that advances and in substantial level and slip car in the situation of the engine resistance torque that obtains, wherein a large amount of fuel/air mixture IC engine supplies so that engine resistance torque significantly but not fully be compensated, for example about 80% compensated.
After the step S6, at step S7, again read the setting of present engine speed and current throttle pedal and brake petal, in step S8, detect one of them that whether satisfies following three conditions: at first be that engine speed N is higher than threshold value Nmax, next be engine speed N near idle speed L, the 3rd is to depress gas pedal or brake petal.If the testing result of step S8 is no, then route is turned back to step S7.If the testing result of step S8 is yes, then at step S9, the end vacation is slided and route is turned back to step S2.
If the driver does not want to reach idle speed, then he can gear shift and need not to finish vacation and slide.
If the rotational speed of the internal-combustion engine of operation is slightly higher than idle speed, then the fuel consume of non-loaded internal-combustion engine is also only higher slightly.This point can be clearly as seen from Figure 2, Fig. 2 shown typically overcome the necessary internal-combustion engine average working pressure of engine friction fmep(rubbing device effective pressure), it is the function of engine speed.Based on this reason, carry out above-mentioned vacation in the situation that can not have on the whole fuel consume to rise and slide, because for sliding without vacation, it is farther that motor vehicle can slip car in coast period generally.The power consumpiton of false coast period adds that with overcoming the necessary power of engine friction the required power sum of supplementary equipment is corresponding, and supplementary equipment is such as being generator and the air-conditioning compressor that is driven by combustion engine mechanical.
Yet under relatively high rotational speed, the balance of motor also is not suitable for, because false sliding can be that arbitrarily speed and the manual transmission that is limited in the motor vehicle with manual clutch is limited in the rotational speed that is lower than threshold value Nmax.Threshold value Nmax is arranged to equal or is substantially equal to engine speed suit, be higher than this engine speed, the fast changeable device of shelves on the instrument panel can indicate him should change to more high-grade speed to the driver.
