The specific embodiment
Referring to figs. 1 through 5A, expression has the power actuated vehicle 1 of driving engine 2, and wherein driving engine 2 is connected with manual six speed transmissions/change-speed box 3 through the power-transfer clutch 2 ' that is installed on the engine drive flywheel.The operation of electronic controller 4 with control driving engine 2 is provided, and electronic controller 4 comprises engine controller 6 and the serviceability of transmission state module 5 with definite change-speed box 3 in the case.
Change-speed box has a plurality of gear ratios of selecting through " H " type driving selection mechanism (gear ratios) (partly illustrating among Fig. 5 A).With regard to shown in six speed transmission 3 with regard to, forward gear is arranged in two row, makes all odd number gears be arranged in first row (R1 among Fig. 5 A) and all even number gears are arranged in parallel second row (R2 among Fig. 5 A) with first row.
Gear also is arranged in three row, make that a retaining and two retainings are arranged in first row (C1 among Fig. 5 A), three retainings and four retainings be arranged near in the secondary series (C2 among Fig. 5 A) of the first row C1 and five retainings and the 6th keep off being arranged on and be listed as in (C3 among Fig. 5 A) near the 3rd of secondary series.In the case, reverse gear be arranged on the first row R1, in the offside of secondary series C2 another row near the first row C1.The layout of taking the gear of this mode is known and with no longer further explain.
The invention is not restricted to the use of the illustrated PWM magnetic pickup device PLCD that uses magnet and export (the linear contactless displacement of the permanent magnetism) sensor of GB-A-2466040 as transmission state sensor (being also referred to as the LVDT sensor sometimes) generation PWM; And can use the displacement pickup of other type; For example, still use magnet and generate the Hall transducer of PWM output.In addition, the invention is not restricted to use the sensor that produces PWM output, can be suitable for using the displacement pickup that generates variable voltage output rather than PWM output signal equally.Unique requirement is, can be used to determine whether to select odd number gear or even number gear from the signal or the output of transmission sensors 7.
Operation as follows; When confirming that through vehicle speed sensor or other device power actuated vehicle 1 is static, promptly the speed Vs of power actuated vehicle 1 comes down to zero and when having preparatory rated conditions of use, and the behavior of for example depressing pedal of clutch through chaufeur separates power-transfer clutch 2 '; Whether electronic control unit 4 operationally utilizes transmission state module 5 inspection change-speed boxs 3 to put into gear; And if it is put into gear, the gear that inspection is selected is odd number gear or even number gear.
If the gear of selecting is the odd number gear; Then electronic control unit 4 is set to first through control unit of engine 6 with the idling of driving engine 2 and confirms that in advance grade is to prepare starting; And if the gear of selecting is the even number gear, then electronic control unit 4 is set to the idling of driving engine 2 through control unit of engine 6 and is higher than first and confirms that in advance second of grade confirms that in advance grade is to prepare starting.Should recognize that the idling of under both of these case, setting all is higher than the normal idling of driving engine 2.
With regard to diesel motor, the idling and second that first definite in advance grade can be 1500RPM confirms that in advance grade can be the idling of 1800RPM.These idling grades will depend on the type of employed driving engine in the power actuated vehicle 1.That is, petrolic torque curve is different with the torque curve of diesel motor, so in order to realize identical output torque, petrolic first and second grades may be higher than first and second grades of the diesel motor of same capability.
Therefore, if change-speed box is placed in two retaining rather than retainings by accident, driving engine 2 rotates start assisting thus with related inertia with higher speed.This is because the moment of torsion output trend of the driving engine of fair speed is higher, but also can be used for start assisting because of the inertia in the flywheel.
At present embodiment on the other hand, elected choosing spouse during several gear, electronic control unit 4 can be operationally provides warning to the chaufeur of power actuated vehicle 1, for removing the wrong choice of gear keeping off the chance of being revised is provided.Fig. 1 representes and electronic control unit 4 bonded assembly chaufeur warning devices 25, and Fig. 4 representes to be used to activate the logic of warning device 25.Therefore, as long as select the even number gear, thereby warning device 25 reminds chaufeur to select the gear except a retaining to start to walk with regard to being activated.
According to another embodiment, based on the setting of vehicle load coefficient adjustment engine idle.The vehicle load coefficient can be power actuated vehicle 1 residing ground-surface inclination angle, power actuated vehicle 1 weight, whether have trailer to be connected to power actuated vehicle 1, maybe will to influence in any other deciding factor of starting of power actuated vehicle 1 one or more with the ambient air temperature of the height above sea level of the weight of power actuated vehicle 1 bonded assembly trailer, vehicle operating place, power actuated vehicle present position.
Fig. 3 representes how this load coefficient is confirmed to combine to produce engine idle request (ISR) with gear.This crosses range request is the base level of confirming engine idle in the confirming of odd number or even number by the gear of selecting.Also confirm load coefficient based on above listed one or more load coefficients.Should recognize that load coefficient will be positive load coefficient usually, mean that the idling base level of having no alternative but to comply increases, but load coefficient also possibly be the load coefficient of bearing, for example power actuated vehicle 1 is on the downhill path.
Then load coefficient is combined with the base level of confirming from gear, be used to the ISR that driving engine 2 produces control signal with generation.
Should recognize that load coefficient can be made up of the load coefficient of some combinations, and some load coefficients can be positive, bonded assembly trailer for example, and some can bear, and for example vehicle is on downward slope.
Although up to the present the present invention is illustrated with reference to starting forward, should recognize, also be suitable in the starting of astern direction.Through be used to from the output of the switch (shown in the RS among Fig. 1) that reverses gear to forward gear with reverse gear that to select to distinguish be possible, the switch that wherein reverses gear is used to open the backing-up lamp related with power actuated vehicle 1.
In example; Reversing gear of providing is in the row identical with the odd number forward gear, but should recognize, it also can be in the row identical with the even number gear; Under any situation, the switch that reverses gear may be used to indicate the idling of the selection of reversing gear and suitable selection.
The idling of the selection that is used to reverse gear can be identical with the idling of selecting for the odd number forward gear, perhaps can be the different idling that depends on the concrete gear ratio that is used to reverse gear.
Utilize the advantage of the embodiment of neutral sensor to be, if select except that a retaining or the forward gear two retainings, transmission state module 5 can not be distinguished each selectable gear, and it only can confirm that the gear of selecting is odd number gear or even number gear.Yet, in fact, be well known that most of frequent faults are to select two retaining rather than retainings, therefore in most of the cases when wrong generation, the present invention will provide the starting of improvement.
Shown in Figure 2 is basic flow sheet according to the method for the operating motor vehicle of the first embodiment of the present invention.Whether in fact null step 10 begins this method from the speed Vs that checks vehicles, if this method gets into step 11, but if not, this method rests on step 10.
In step 11, through the indication of checking whether pedal of clutch is depressed and provides starting whether to take place.If be depressed the signal that pedal of clutch receives from the pedal of clutch sensor like electronic control unit 4 is indicated, electronic control unit 4 is used to determine whether to select whether the gear of gear and selection is the gear of odd number in step 12 and 13 respectively from the output of transmission state module 5 so.If do not select gear, this method is circulated back to step 12 from step 12 so in this case, but can also be circulated back to step 11.
Yet, be the odd number gear if selected gear and gear, so this method from step 13 get into for starting select or set first confirm the idling grade in advance step 14.This method finishes in step 16 then.
If confirm that in step 13 gear of selecting is the even number gear, this method gets into from step 13 and selects or set the step 15 that second of idling is confirmed grade in advance so.Second confirms that in advance grade is higher than first and confirms grade in advance so that auxiliary two retaining startings.
After step 15, this method finishes in step 16.
Should recognize, the invention is not restricted to exact method shown in Figure 2, and the various varied of step also can be used to produce identical result.For example whether the test in the step 13 can select the even number gear, and in this case, the result will cause this method to get into step 15 from step 13, and the result will cause this method to get into step 14.
In addition, if the answer of the test in the step 13 is " denying ", so warning or remind the step of chaufeur can be included in by step 13 through step 15 in the circulation of step 16.
Referring now to Fig. 1 and Fig. 5 A to 7, be depicted as the second embodiment of the present invention.
In the case, except that transmission sensors 7 was the form with the gear position sensor that formed by a plurality of proximity transducer S1, S2, S3, S4, S5, S6 and SR in the case, power actuated vehicle 1 was identical with before power actuated vehicle.Term gear position sensor the meaning here is the sensor that the output of the gear that in fact indication select can be provided.That is, in the case, transmission state module 5 can provide the indication of the gear of current selection.
Specifically with reference to Fig. 5 A and 5B; Change-speed box 3 has multiple gear ratio; These gear ratios can be selected through " H " type driving selection device mechanism (not illustrating fully), and wherein " H " type driving selection device mechanism has the H type finder panel 20 of the groove that limits the shaping that engages with shifter bar.H type finder panel 20 limits a plurality of a plurality of finders positions corresponding to the various gear ratios that provided by change-speed box 3 thus.With regard to shown in six speed transmission 3 with regard to, forward gear is arranged in two row, makes all odd number gears be arranged on first row (R1 among Fig. 5 A) and all the even number gears and is arranged on second row (R2 in Fig. 5 A) parallel with first row.
Gear also is arranged in three row, makes a retaining and two retainings be arranged on first row (C1 among Fig. 5 A), three retainings and four retainings and is arranged on to keep off being arranged near the 3rd of secondary series near the secondary series (C2 among Fig. 5 A) of the first row C1 and five retainings and six and is listed as (C3 among Fig. 5 A).In the case, reverse gear be arranged on the first row R1, in the offside of secondary series C2 another row near the first row C1.The layout of gear by this way is known, and with no longer further explain.
Shown in Fig. 5 B, proximity transducer S1, S2, S3, S4, S5, S6 and SR are arranged on corresponding to the position of the engage position of change-speed box 3 in abutting connection with the groove that is shaped.In Fig. 5 A, shown shifter bar is in corresponding to a retaining that is labeled as 21a and is labeled as the position that two of 21b keeps off, and in Fig. 5 B, shown shifter bar is in corresponding to one of mark 21a and keeps off and be labeled as the position of the neutral of 21c.
When shifter bar 21c is in neutral, its not with proximity transducer S1, S2, S3, S4, S5, S6 and SR in any one enough near activating them, so transmission state module 5 can be interpreted as the neutral gear position state with it.Yet when shifter bar 21a moves to when retaining, it is positioned near sensor S1, so sensor S1 is activated and transmission state module 5 is interpreted as change-speed box 3 with it and is in a retaining.When shifter bar moves to when comprising any other gear that reverses gear, produce similar effects, so transmission state module 5 can be confirmed the actual gear selected in the change-speed box 3.
Should recognize, the invention is not restricted to the use of such gear position sensor, and can use the sensor of the indication of other gear that current joint can be provided.The use that it is to be further appreciated that gear position sensor is not limited to H type finder layout, and can use other finder to arrange.
Operation as follows; When confirming that by vehicle speed sensor or other device power actuated vehicle 1 is static; Be that the speed Vs of power actuated vehicle 1 comes down to zero and when having preparatory rated conditions of use, the behavior of for example depressing pedal of clutch through chaufeur separates power-transfer clutch 2 ', and whether electronic control unit 4 operationally utilizes transmission state module 5 inspection change-speed boxs 3 to put into gear; And if it puts into gear, which gear inspection has selected.
If the gear of selecting is not a retaining or two retainings,, through 25 pairs of chaufeurs of warning device warning is provided, then EO so for this embodiment.
Alternatively; If the gear of selecting is a retaining; Then electronic control unit 4 is set to first through control unit of engine 6 with the idling of driving engine 2 and confirms that in advance grade is to prepare starting; And if the gear of selecting is two retainings, then electronic control unit 4 is set to the idling of driving engine 2 through control unit of engine 6 and is higher than first and confirms that in advance second of grade confirms that in advance grade is to prepare starting.
As previously mentioned, be first and second to confirm that in advance actual value that grades are selected will depend on some factors of the driving device of the weight that comprises the engine type that uses in the power actuated vehicle 1, power actuated vehicle 1 and power actuated vehicle 1.Yet, should recognize that the idling of setting is higher than the normal idling of driving engine 2.
Therefore, because aforementioned reason, if accidentally change-speed box is placed two retaining rather than retainings, then driving engine 2 rotates with higher speed with related inertia, thus start assisting.
When selecting except that a retaining or the gear two retainings, the chaufeur of 4 pairs of power actuated vehicles 1 of electronic control unit provides warning, and the chance (selection 1 among Fig. 7) of correction is provided for the wrong choice except that a retaining or the gear two retainings thus.This is because for power actuated vehicle 1, the starting that keeps off at a retaining or two is acceptable.Yet for the power actuated vehicle of other type, it is acceptable having only a retaining starting, in the case, warning (selection 3 among Fig. 7) can be provided also when selecting two retainings.Under these circumstances, as previously mentioned, assist two retaining startings, but report to the police or alarm dissuasion two retaining startings through chaufeur is provided through increasing engine idle.It also is possible that warning as selecting 2 and 4 indicated selecting to reverse gear among Fig. 7 is provided.
Although the present invention has been carried out as above explanation, should recognize that the present invention can also be applicable to the starting of reversing gear with reference to starting to walk forward.In the case, the idling that is used for a retaining or two retainings can be used to reverse gear, and perhaps can basis keep off the different idling of comparing of the gear ratio of reversing gear use with a retaining or two.
As previously mentioned can be based on the setting of vehicle load coefficient adjustment engine idle.
For example, if power actuated vehicle 1 is static on the slope, then can utilize following equality to set engine idle:
ISR=ISG+ISL perhaps
ISR＝ISR*(ISL)
Wherein ISR is the engine idle request that sends to driving engine 2, and ISG is based on the definite engine idle of gear of selection, and ISL is based on the engine idle correction of load.
For example, and without limitation, be 1600RPM if come from the idling ISG of gear, power actuated vehicle 1 is on the slope, needs the idling of 160Rpm or 10% to promote thus, and then ISR can obtain from following:
ISR=1600+160=1760RPM perhaps
ISR＝1600*(1.1)＝1760RPM。
Yet, should recognize that the also otherwise application of application load coefficient is for example through one or more look-up tables.
Fig. 6 representes the basic flow sheet of the method for operating motor vehicle according to a second embodiment of the present invention.Whether in fact null step 100 begins this method from the speed Vs that checks vehicles, if then this method gets into step 110, but if not, then this method rests on step 100, and reason is that the present invention only relates to from static starting.
In step 110, through the indication of checking whether pedal of clutch is depressed and provides starting whether to take place.If be depressed the signal that pedal of clutch receives from the pedal of clutch sensor like electronic control unit 4 is indicated, electronic control unit 4 is used to determine whether to select whether the gear of gear and selection is a retaining or two retainings in step 120 and 130 respectively from the output of transmission state module 5 so.If do not select gear, this method is circulated back to step 120 from step 120 so in this case, but can also be circulated back to step 110.

Should recognize that the difference between each idling grade can be unified, can be relevant or can be based on some such other factorses of limited speed grade for example with gear ratio.For example, and without limitation, because the restriction of the driving performance as NVH; The idling grade of the maximum possible that allows can be 2400RPM; And the idling grade can be set to grade 1=1500RPM, grade 2=1800RPM, grade 3=2000RPM; Class 4=2200RPM, class 5=2300RPM and class 6=2400RPM.
As previously mentioned, can be based on the vehicle load coefficient, adjust these idling grades up or down according to the influence of load coefficient.
The engine idle grade that is used for reversing gear and the Fig. 8 that illustrates is used for the identical of a retaining, but situation needn't such was the case with.
As previously mentioned, if desired, can warning be provided to the chaufeur of vehicle, and the selection shown in Fig. 71 to 4 is possible Alert Policy.It also is possible having second-level alarm or reporting to the police; For example; When using, make the illumination or the alphanumeric information of using up, when starting can cause undue wear maybe can cause stopping working such as the such gear of not advising of two retaining startings; When for example starting to walk, use flash of light or the so stronger warning of audible alarm with the gear that is higher than two retainings.
Fig. 9 representes the basic flow sheet according to the method for the 3rd embodiment operating motor vehicle of the present invention.Whether in fact null step 200 begins this method from the speed Vs that checks vehicles, and if, then this method gets into step 210, but if not, then this method rests on step 200.
In step 210, through the indication of checking whether pedal of clutch is depressed and provides starting whether to take place.If be depressed the signal that pedal of clutch receives from the pedal of clutch sensor like electronic control unit 4 is indicated, electronic control unit 4 is used to determine whether to select gear and selected which gear in step 220 from the output of transmission state module 5 so.If do not select gear, so in this case, this method is circulated back to step 210 from step 220, but can also be circulated back to step 210.Yet if selected gear, this method gets into the step 230 based on the gear setting engine idle grade of selecting as shown in Figure 8 from step 220 so.
This method gets into step 250 then, and in step 250, if the gear of selecting is not a retaining, then it is assigned to step 260 and has selected the gear except that a retaining with alerting driver, finishes in step 270 then.Therefore this method is corresponding to the selection among Fig. 73.Yet should recognize that the test through being fit to step 250 utilization can realize the various selections shown in Fig. 7.
If confirm that in step 250 gear of selecting is a retaining, alarm or warning are not provided so, and this method finish in step 270.
