Description
Technical field
The present invention relates to the method for the taxiing operation of the power actuated vehicle being equipped with actuating device and drg, drg activated by brake pedal.The invention still further relates to the actuating device implementing the method.
Background technology
Due to the restriction of the deposit of fossil/fossil energy, particularly owing to obtaining the limited availability of the oil of the raw material running fuel needed for explosive motor, in explosive motor evolution, drop into continuous effort to minimize consumption of fuel.On the one hand, the prospect of these effort is to improve, namely more effective, burning.And on the other hand, the specific policy about explosive motor basic operation is also actv..
The idea improving fuel consumption in vehicles comprises, and such as, if do not have instantaneous power demand, then closes explosive motor, instead of makes it run continuously in the idling state.In practice, this means at least to close explosive motor when vehicle stops.A utilization of this idea is exactly, such as, and the traffic that stops and goes occurred when express highway and backbone highway occur to block.In the traffic in urban district, owing to there is the result of the traffic signal lamp system do not coordinated mutually, the traffic that stops and goes is no longer exception and becomes rule.Limited junction railway and so on provides further example.
For the consumption of fuel strategy reducing explosive motor taxiing operation (now not having instantaneous power demands equally), there is similar departure point and combine the concept of aforementioned type equally.
The strategy of all reduction taxiing operation consumption of fuels is all delivered to the general way of the lock torque of transmission system based on explosive motor when being reduced in taxiing operation, reduces slow down and extend the distance can be passed through caused due to vehicle energy from given car speed v with this.Because in taxiing operation, fuel supply is closed usually, namely be stopped, so the increase of distance along with taxiing operation process, total consumption of fuel of vehicle is lowered, and this is because consumption of fuel is calculated by the fuel quantity that uses and the distance passed through under this fuel quantity.Such as, but be different from aforementioned idea, explosive motor is not closed but continues to run, idle.
In the present invention, traditional taxiing operation is understood to the running state of explosive motor or vehicle, and in this condition, power-transfer clutch closes, and namely engages, and there is not loading demand; That is, chaufeur does not have actuating accelerator pedal.In the present invention, the common ground of various taxiing operation there is not loading demand.
According to prior art, the throttle gate be arranged in inlet channel is closed completely when taxiing operation, therefore due to piston sustained oscillation, creates negative pressure in the downstream of throttle gate, which results in the pump gas of so-called explosive motor.Consequently need to perform extra inflation exchange work.This inflation exchange work defines the pith of the lock torque being delivered to transmission system when taxiing operation from explosive motor.
A kind of strategy reducing consumption of fuel when taxiing operation, it is equally at Automobiltechnische Zeitschrift, within 1999, No. 9 438 pages are described, and this strategy proposes the cut-off clutch when taxiing operation and thus reasonable match other parts is separated.The deceleration of power actuated vehicle is lowered in this way, this is because as hindering factor, the lock torque being usually delivered to vehicle when taxiing operation by explosive motor is eliminated.Along with disengaging of clutch, therefore car retardation determines primarily of rolling resistance and air resistance.But the prerequisite that this strategy is implemented is can the power-transfer clutch of self actuating, namely activates by electronic control system and does not need driver to participate in the power-transfer clutch of (namely performing)
Although for determining that the driving cycle that consumption of fuel specifies generally includes the decelerating phase, this decelerating phase needs the actuating of car brakeing owing to needing larger deceleration gradient, and is therefore unsuitable for the strategy reducing the consumption of fuel of explosive motor when taxiing operation by reducing lock torque.But it is more and more frequent that the decelerating phase being feature with little deceleration gradient in the highway communication of reality occurs, and a class strategy is hereafter discussed is used in fuel saving in above-mentioned situation.
Summary of the invention
In this context, the first object of the present invention be illustrate say according to the present invention disclosed for equipping the method for the taxiing operation of the power actuated vehicle of actuating device.Compared with method of the prior art, further can be reduced the consumption of fuel of power actuated vehicle by this method.
Another object of the present invention is to provide the actuating device realizing this method.
By the method for the taxiing operation of the power actuated vehicle for equipping actuating device and drg, the first object of the present invention is implemented, and wherein drg is activated by brake pedal.This actuating device comprises explosive motor and has can the change-speed box of power-transfer clutch of self actuating, and explosive motor has fuel supply system to unify at least one inlet channel of supplied fresh air, throttle gate is placed in inlet channel, wherein, pass through electronic control system, with the function of engine speed n and the instant Transmission gear m selected, reduce the deceleration of power actuated vehicle in taxiing operation, wherein in the first operational mode, by regulating throttle gate in open position direction, or in the second operational mode, pass through cut-off clutch, the output valve that the operational mode adopted maps as the input-output being stored in control system is read, and engine speed n and Transmission gear m is used as input value.
In this innovative approach, deceleration when betiding taxiing operation is by a reduction in two possible processes, actual adopted process is determined by engine speed n and Transmission gear m, and be under the boundary condition existed in two processes on fuel consumption perspective better process.
For reducing by first possible process of slowing down during taxiing operation, it is also called as the first operational mode under taxiing operation background, is provided in the direction adjustment throttle gate of open position.
Contrary with method of the prior art, in the method according to the invention, the throttle gate be arranged in inlet channel is not close completely or keep to close when taxiing operation, but opens with width more or less.When piston sustained oscillation, throttle gate open the formation negative pressure counteracted in throttle gate downstream, decrease the energy dissipation of burn engine because gas exchanges produces.As the result of this measure, the lock torque being delivered to transmission system and vehicle by explosive motor is eliminated.Thus the deceleration of self-propelled vehicle is reduced, and therefore, under the condition that car speed is identical, power actuated vehicle can move longer distance.Consumption of fuel is lowered.
During taxiing operation, reduce the process that the second of car retardation is possible, it is also called as the second operational mode under taxiing operation background, provides cut-off clutch and is separated the remainder of explosive motor and transmission system.To put on the process of lock torque on transmission system and vehicle contrary with only reducing driving engine according to the first operational mode, according to the second operational mode, in the operational process of explosive motor, the lock torque that explosive motor applies thoroughly is eliminated as hindering factor.
Under all operations condition, any one in two described processes is more superior unlike another at fuel consumption perspective.When taxiing operation, the one reduced in aforementioned two kinds of means of car retardation use is identified and fixes in the first treatment step.In this case, read by the operational mode used from the input-output being stored in electronic control system maps.
It is that vehicle is specific that input-output maps, and can produce by experiment on test cell, or is mathematically produced by the means of emulation.Engine speed n and Transmission gear m is used as input value to read by the operational mode used.It should be noted that other operational factor of hypothesis driven device and vehicle, such as car speed v, can from mentioned two operational factors, namely derive in engine speed n and Transmission gear m, then this operational factor also can be used as input value.The operational mode used under institute's current operating condition is better one at fuel consumption perspective.Being stored in three-dimensional input-output mappings in control system can be with, and such as, the form of multiple queries table stores.
The invention provides a kind of method of taxiing operation of the power actuated vehicle for equipping actuating device, pass through the method, the consumption of fuel of power actuated vehicle when taxiing operation can be further reduced compared with method of the prior art, and therefore first object of the present invention is implemented by the method for this innovation.
The method of this innovation not only usually achieves the deceleration reduction of the vehicle when taxiing operation, but also when the first operational mode, the step-less adjustment that close or open lock torque that explosive motor applied greater or lesser by throttle gate becomes possibility, and therefore makes the deceleration of the adaptation situation satisfied the demands become possibility.
In the first operating mode, explosive motor is applied to the lock torque on vehicle and is conditioned by the position of throttle gate, and therefore the embodiment of this method is also very favorable.
The variant of other advantages of this method is discussed below.
In the first operating mode, this method embodiment that throttle gate is opened completely is favourable.
According to this variant of this method, the lock torque that explosive motor is applied on vehicle is in the first operating mode minimized, and therefore during taxiing operation, car retardation is reduced as much as possible.
From the Transmission gear of given car speed and selection, can the distance of movement be maximized when taxiing operation, therefore the consumption of fuel of vehicle is minimized.
In the first operating mode, the fuel of explosive motor supplies the embodiment of this method be stopped is favourable.
Because taxiing operation does not have power demand, the fuel supply cutting off explosive motor is in the first operating mode favourable.Stopping due to fuel combustion also avoid the generation of pollutants, so fuel shutoff supply is not only favourable to minimizing consumption of fuel, and is also favourable to reduction pollutant emission.
In the second operating mode, in this method embodiment, explosive motor is idle is favourable.
Equally in the second operating mode, due to taxiing operation, so there is no power demand.Even if consider the wearing and tearing of noise emissions and explosive motor, explosive motor is made to operate in idling speed, namely idle, be also favourable.
In principle, explosive motor also can be closed in the second operating mode.
In the embodiment of this method, closed by the actuating throttle valve of brake pedal in the first operating mode, and engaging clutch is favourable.
In the embodiment of this method, by the actuating of brake pedal, power-transfer clutch is engaged in the second operating mode, and close the throttle is also favourable.
According to the above-mentioned two kinds of variants of this method, the actuating of brake pedal may be interpreted as chaufeur and judges that in the first operational mode or the car retardation that generates in the second operating mode be insufficient.That is, the actuating of brake pedal can be considered to need to increase car retardation.
Therefore, by the application of electronic control system, vehicle automatically, that is, without the need to chaufeur pro-active intervention ground, can be transformed into power-transfer clutch engagement and traditional taxiing operation state of closed throttle.
In this embodiment of this method, it is favourable that the fuel supply of explosive motor is stopped.
Can with reference to the published content about fuel cut-off.
Part II object of the present invention, namely the actuating device performed based on the method for one of aforementioned variant is provided, that the actuating device consisted of the change-speed box comprising explosive motor and have power-transfer clutch realizes, wherein explosive motor is equipped with at least one inlet channel that fuel supply system is unified for carrying fresh air, throttle gate is arranged in this inlet channel, and power-transfer clutch and throttle gate are automatically activated by electronic control system in this actuating device.
Feature according to method of the present invention is also applicable to according to actuating device of the present invention.

Enforcement due to method needs taxiing operation state, and this prerequisite is tested in the process first step.If vehicle is not in traditional taxiing operation state, so the method terminates.
From traditional taxiing operation state of power actuated vehicle, whether brake pedal activated detected.The actuating of brake pedal is assessed as the demand increasing car retardation, and the action that vehicle is switched to the first operational mode or the second operational mode in the case can not perform, this is because it can cause the reduction of car retardation, the requirement of this and chaufeur is runed counter to.And according to the actuating of brake pedal, vehicle is switched to traditional taxiing operation, or continue to start to run in traditional taxiing operation of place supposition in such as this method, wherein engaged the and throttle gate of power-transfer clutch is closed.
But, if brake pedal does not activated, then suppose that the deceleration of vehicle can be reduced to reduce consumption of fuel.
Therefore, vehicle by electronic control system automatically, namely without the need to chaufeur pro-active intervention ground, is transformed into the first operational mode or the second operational mode.
First the operational mode of place in operation is read as the output valve mapped from the input-output stored in the controls, for this purpose, must be determined as the engine speed n of input value and Transmission gear m.Under current operating condition, the actual operational mode used is more favourable on fuel consumption perspective.
The first operational mode for reducing the deceleration in taxiing operation is provided in open position direction and regulates throttle gate.That is, the feature of the first operational mode is the throttle gate opened.
The second operational mode for reducing the deceleration in taxiing operation provides cut-off clutch to be separated with the remainder of transmission system to make explosive motor.That is, the feature of the second operational mode is the power-transfer clutch of separation.
From the one in aforementioned two kinds of operational modes, once brake pedal activated, vehicle is just switched in traditional taxiing operation.In traditional taxiing operation, can continue to refresh the test activated brake pedal, once no longer continue the actuating of brake pedal, then be transformed into immediately according to the one in two kinds of operational modes of the present invention.

According to engine speed and Transmission gear, electronic control system can determine that with a first operation mode or the second operational mode runs taxiing operation state.Such as, the input-output be stored in electronic control system maps and can be used for making decision.In input-output maps, operational mode is the function of engine speed n and Transmission gear m.In one example, first group of engine speed n1 and Transmission gear m1 corresponds to the first operational mode, and second group of engine speed n2 and Transmission gear m2 corresponds to the second operational mode.It should be noted that, the first operational mode and the second operational mode can engine speed within the scope of corresponding one and Transmission gear.In addition, it should be noted that, engine speed n1 can equal engine speed n2 and Transmission gear ml can equal Transmission gear m2, but the combination of first group of engine speed and Transmission gear is different from the combination of second group of engine speed and Transmission gear.
It can be that vehicle is specific that input-output maps, and can produce by experiment on test cell, or is mathematically produced by the means of emulation.It should be noted that other operational factor of hypothesis driven device and vehicle, such as car speed v, can from mentioned two operational factors, namely derive in engine speed n and Transmission gear m, then this operational factor also can be used as input value.Replaceable, being stored in three-dimensional input-output mappings in control system can be with, and such as, the form of multiple queries table stores.
