Referring again to Fig. 1, in traditional OEMHDV, by making via manual operation power-transfer clutch 206 primary mover 208 of combustion engine (" ICE ") throw off with Manual transmission 204, gear shift being carried out to the gear case of change speed gear box 204.In above-mentioned related application, disclose a kind of modified node method, wherein electric traction motor/electrical generator (" ETMG ") is connected in Manual transmission via Power output port (" PTO ").According to this kind of structure, be in the ETM pattern of electric traction motor (" ETM ") at the primary mover of vehicle, even if ICE disconnects with change speed gear box by making the conventional clutch of throw-out-of clutch between ICE and change speed gear box throw off.In ETM pattern, can not use this kind of power-transfer clutch, namely power-transfer clutch continue throw off condition under carry out gear shift.But in order to change to new gear, first change speed gear box must change to neutral gear, then ET electrical motor rotating speed must with the rotational speed matches of the new gear of speed-change gear box.

Referring now to Fig. 2, the block diagram having the OEMHDV202 of electric traction (" ET ") system according to one embodiment of the invention repacking is shown.Change speed gear box 204 shown in Figure 1, power-transfer clutch 206, ICE208, gear-shift lever 210, pedal of clutch 212, steering handwheel 214, battery 216 and electric system 218.Power conversion unit (" PXU ") 304 is connected in the transmission gear (not shown in fig. 2) of change speed gear box 204 via PTO port 302 (being also called herein " gearbox inbound port ").ETMG306 is mechanically connected in PXU304 via the axle (or gear) of ETMG306.The electrical connection of ETMG306 is connected to rectifier/inverter 308, and when ETMG306 drives using during as generator operation by PXU304, this rectifier/inverter exports the electric power of ETMG306 and changes to charge to battery pack 310.When ETMG306 works as electrical motor, the electric energy stored by rectifier/inverter 308 pairs of battery pack 310 is changed, and to drive ETMG306, and this ETMG306 mechanically drives PXU304 with the transmission gear via change speed gear box 204 to order about vehicle 202.In one embodiment of this invention, battery pack 310 can be AltairNanotechnology15KWh300-400VDC.

Although ETM speed adjusts by the manual operation of accelerator pedal 213, and although the embodiment with velocity indicator and automatic controlling feature that relevant patent application discloses this invention can contribute to making the speed of ETM and the speed of gear case to match further, but still following situation can be there is: in ETM pattern, wish in response to the motion of traditional pedal of clutch and gear case gear is unloaded or unloaded at least partly.That is, the motion of vehicle causes rotation of wheel, and rotation of wheel causes again gear case gear to rotate.When speed-change gear box is connected to ICE crank shaft or is connected to ETMG axle, even if ICE or ETMG rotates freely, gear case gear still stands the larger torque load caused by the load of ICE or ETMG on gear case gear.May it is desirable to by making ICE or ETMG and gear case disconnect reducing torque load.

In addition, advantageously, in fact chaufeur can carry out gear shift in the mode identical with ICE pattern in ETM pattern, namely throws off to make primary mover and change speed gear box 204 by pressing down pedal of clutch, and no matter primary mover is ETM306 or ICE208.

Referring now to Fig. 3, a kind of according to an embodiment of the invention structure is shown, this structure make traditional pedal of clutch 212 can operate PXU power-transfer clutch 545 when ETM pattern and in ICE pattern time operation ICE power-transfer clutch 206.Power-transfer clutch 206 is thrown off for making ICE and Manual transmission 204.Should be understood that, accompanying drawing illustrates the attaching parts between actuator 412 and power-transfer clutch 216 substantially, but is to a certain degree schematic in itself.That is, in figure 3, some mechanical details can be omitted or some mechanical details are symbolically shown, to clearly show that the specific features how illustrated structure operates and aspect.Such as, even if PXU304 has fixed drive ratio, PXU304 also can have two or more gear.But in figure 3, PXU304 is shown as has single gear.Except actuator 412 of the present invention and the attaching parts that is associated thereof are shown, Fig. 3 also illustrates the traditional connectors for conventional clutch pedal 212 and conventional clutch 206, as mentioned below.

Fig. 3 illustrates that pedal of clutch 212 is in the situation of the wherein dead position that ICE power-transfer clutch 206 is engaged.In order to be thrown off by power-transfer clutch 206, chaufeur presses down traditional pedal of clutch 212 by convention in vehicle cab, produces thus and throws off motion 530.Pedal of clutch 212 is positioned on clutch pedal level 514, and this clutch pedal level 514 is rotatably fixed on pivot point 512, makes to throw off motion 530 and via clutch pedal level 514, disengagement campaign 532 can be passed to connecting rod 520.Connecting rod 520 has far-end, and this far-end and connecting rod 520 are relative and be rotatably connected to connecting rod 522 at connecting portion 538 place with the auxiliary section of pedal of clutch 514.In addition, connecting rod 520 is rotatably fixed on pivot point 513.Therefore, disengagement campaign 532 is passed to connecting rod 522 by connecting rod 520, causes in connecting rod 522 and occurs to throw off motion 534.Connecting rod 522 has far-end, the connection part of this far-end and this connecting rod and connecting rod 520 is relative and be rotatably connected to clutch arm 524, and this clutch arm is rotatably connected to power-transfer clutch 206 and coordinates with the withdrawal bearing (not shown) of power-transfer clutch 206.Therefore, disengagement campaign 534 is passed to clutch arm 524 by connecting rod 520, cause and produce disengagement motion 536 by clutch arm 524, this causes the withdrawal bearing of power-transfer clutch 206 to be thrown off by power-transfer clutch 206, makes crank shaft 110 and transmission input shaft 125 throw off thus.

According to one embodiment of the invention, actuator 412 and the attaching parts that is associated thereof can apposition as described below in above-mentioned traditional connectors.Actuator 412 rotatably can be fixed on vehicle chassis at pivot point 516 place at one end.Actuator 412 the other end place of this actuator 412 extensible/regracting axle 542 (be shown as in figure 3 and be in bending retracted position) can be fixed on the connecting portion 538 of connecting rod 520 and 522 by cover cap 540, connecting rod 520 and 522 is made to have abundant exercise degree of freedom, to make to carry out traditional operation as above by stretcher 212, but cover cap 540 and being fixedly connected of connecting portion 538 make it pass through to be driven towards its complete extended position by actuator shaft 542, making actuator shaft 542 still can pass to connecting rod 522 by throwing off motion 534.

Reaffirm following, structure shown in Fig. 3 allows the degree of freedom of connecting rod 520 and 522 conventional motion of conventional clutch pedal 212, operate under the condition that can extend not making the axle 542 of actuator 412 to make power-transfer clutch 206 or retract, axle 542 traditional connectors of apposition between power-transfer clutch 206 and pedal of clutch 212 of this actuator 412.That is, cover cap 540 fully loose ground catches connection part 538, to allow this kind of degree of freedom of conventional motion, but fully catch this connection part 538 tightly, make axle 542 in the whole conventional motion scope of pedal of clutch 212 and in the corresponding range of movement of connection part 538, keep coordinating with connection part 538.In addition, this kind keeps cooperation to make actuator 412 can be provided for the replacement device that power-transfer clutch 206 is thrown off and is re-engaged.In order to throw off, actuator 412 carries out disengagement campaign 534 by making axle 542 extension carry out drive link 522.Traditional power-transfer clutch 206 comprises spring return mechanism (not shown in figure 3), and power-transfer clutch 206 is re-engaged only by making axle 542 retract.That is, the spring return mechanism of power-transfer clutch 206 makes clutch arm 524 move to and is re-engaged position, makes cover cap 540 and connection part 538 even keep when axle 542 is retracted coordinating.

Be arranged on the position of limit switch 416CR on actuator 412 and 416CD sensitive axis 542, and by control logic (according to various embodiments of the present invention shown in Fig. 5 B, 6B and 7) for determining when that start and stop makes actuator move between extended position and retracted position.Such as, the limit switch 416CR of actuator can close sensing actuator 416 from the condition that complete retracted position is removed, and limit switch 416CR can open sensing under the condition that actuator 412 retracts completely.

In one embodiment of this invention, power-transfer clutch 545 (comprising actuator) is located between ETMG306 and PXU304.In addition, provide connecting rod 520P, with the motion in response to pedal of clutch 212 as described below, power-transfer clutch 545 is thrown off.The attaching parts of pedal of clutch 212 comprises connecting rod 520, and this connecting rod 520 certain some place at it in spherical or stem portion contacts with clutch pedal level 514.Connecting rod 520P contacts with clutch pedal level 514 at certain substantially the same some place, and be loaded with spring 550, thus when ETM pattern, even make after connecting rod 520, connecting rod 522 and clutch arm 524 move to ICE throw-out-of clutch position at actuator 412, clutch pedal level 514 is held in position same as shown in Figure 3 by spring 550 and connecting rod 520P, otherwise clutch pedal level 514 can discharge from its clutch position.

There is provided control logic 555, and this control logic can operate and is in ICE pattern or ETM pattern with senses vehicle.In response to chaufeur pressure pedal of clutch 212, connecting rod 520P operates electrically or hydraulic efficiency pressure switch 552.In addition, switch 552 signal that responsively makes control logic 555 send pedal 212 to be depressed.Be in ETM pattern in response to accepting this kind of signal and sensing vehicle, control logic 555 operates the actuator of PXU power-transfer clutch 545, makes power-transfer clutch 545 move to disengaged position.In contrast, when chaufeur is at ETM pattern release the clutch pedal 212, spring 550 for connecting rod 520P makes connecting rod 520P (correspondingly pedal of clutch 212) be back to the clutch position shown in Fig. 3, make switch 552 responsively make control logic 555 send signal, cause the actuator of PXU power-transfer clutch 545 that power-transfer clutch 545 is moved and get back to engage position.Be in ICE pattern in response to sensing vehicle, the above-mentioned response of control logic 555 override, namely ignores the signal that pedal 212 has been depressed, thus logic 555 does not cause the actuator of PXU power-transfer clutch 545 to make power-transfer clutch 545 move to disengaged position.

Said structure makes traditional pedal of clutch 212 can operate PXU power-transfer clutch 545 when ETM pattern, and operates ICE power-transfer clutch 206 when ICE pattern.Therefore, thus the viewpoint of chaufeur, no matter be in ETM pattern or be in ICE pattern, prime power is thrown off with change speed gear box 204 in response to being depressed by pedal of clutch 212.Therefore, the idle running response except ET electrical motor and ICE is different, when considering that pedal of clutch operates, in ETM pattern with to carry out gear shift in ICE pattern be all identical.(elimination or slow down hereafter discussing idle running difference in response is described, and has more detailed description in one or more in the above-mentioned related application mentioned.)

One or more describe in detail in response to the instruction signal of hand shift or the intention of hand shift being also noted that in the above-mentioned related application mentioned and change the speed of ETMG306 or carry out torque adjustment.That is, the desired signal that usual control logic produces to ETMG in response to the position of accelerator pedal 213, wherein control logic increases ETMG torque demand in response to the displacement increase of accelerator pedal 213.In response to detecting shift mode, wherein gear shift is just occurring or is occurring at least soon, and control logic reduces torque demand in response to the displacement of accelerator pedal 213.That is, for the displacement of given accelerator pedal 213, control logic produces less torque demand signal when being in shift mode but not being in shift mode.

According to the embodiment with PXU power-transfer clutch 545 described here of the present invention, control logic 555 can be in ICE pattern in response to sense in the positive gear shift of speed-change gear box (or intention gear shift) and sense vehicle and power-transfer clutch 545 is thrown off.This kind of power-transfer clutch 545 can be additional to or replace ETMG speed or torque adjustment in the disengagement of ICE pattern.

Referring now to Fig. 4, according to one embodiment of the invention, a kind of cover type pedal of clutch structure is described, wherein pedal 560 covers traditional pedal 212, and be rotatably connected to pivot point 564 via arm 562, this pivot point 564 is also fixed on fixed position relative to the base plate (Fig. 2) of the operator's compartment of vehicle 202.Therefore, in response to chaufeur pressure pedal 560, cause pedal 560 via arm 562 pivotally 564 rotations thus, this makes pedal 560 depress pedal 212, causes pedal 212 via arm 514 pivotally 512 rotations thus.(range of movement of pedal 560 can be limited by retainer 566).

Now together see Fig. 3 and Fig. 4, according to the structure of cover type pedal of clutch 560, the connecting rod 572 being loaded with spring 574 flexibly coordinates with the arm 562 of pedal 560, thus even when vehicle switches to ETM pattern, pedal 560 is flexibly held in the clutch position shown in Fig. 4, and in ETM pattern, actuator 412 makes ICE power-transfer clutch 206 automatically throw off, and traditional pedal 212 is correspondingly made to move to by the disengaged position of ICE power-transfer clutch 206 shown in dotted lines in Figure 4.Like this, be flexibly held on the pedal 560 of clutch position under the pin of chaufeur still can be resisted against ETM pattern, but ICE power-transfer clutch 206 is thrown off and pedal 212 is depressed due to the effect of actuator 414.

In addition, depress pedal 560 artificially in response to chaufeur, arm 562 makes connecting rod 572 move with actuation switch 576, and this switch 576 makes control logic send signal, and this can hereafter be described further.

Referring now to Fig. 5 A, block diagram format is shown, the pedal of clutch 212 of this prior art shown in block diagram format instruction diagram 1, attaching parts 610 and power-transfer clutch 206 structure.Attaching parts 610 such as can comprise the clutch pedal level 514 shown in Fig. 3 and connecting rod 520 and 522.

Referring now to Fig. 5 B, block diagram is according to an embodiment of the invention shown, this block diagram illustrates and is attached with attaching parts 615 and control piece 620, and this control piece 620 is connected to attaching parts 610 and ICE power-transfer clutch 206.Such as, in the embodiment of the present invention shown in figure, attaching parts 615 shown in Fig. 5 B comprises the connecting rod 520P being loaded with spring 550, and the control piece 620 shown in Fig. 5 B comprises limit switch 416CD with 416CR, for the actuator 412 of ICE power-transfer clutch 206 and switch 552, indicates the control logic 555 of carrying out communicating and the clutch actuator for power-transfer clutch 545 with ICE/ETM pattern.In this embodiment, actuator 412 being not interposing between original clutch pedal level 514 and clutch arm 524.In another embodiment of the invention, control piece 620 shown in Fig. 5 B can comprise and is placed in pneumatic, hydraulic pressure between original clutch pedal level 514 and clutch arm 524 or electrical control logic and device, thus in ICE pattern, while engaging in response to pedal of clutch 212 or throwing off ICE power-transfer clutch 206, control piece 620 automatically keeps ETMG power-transfer clutch 545 to be engaged, and in ETM pattern, while engaging in response to pedal of clutch 212 or throwing off ETMG power-transfer clutch 545, control piece 620 automatically keeps ICE power-transfer clutch 206 to throw off.

As above with reference to accompanying drawing 4 the description carried out, chaufeur can depress cover type pedal 560 artificially, and cause arm 562 that connecting rod 572 is moved, this actuation switch 576 sends signal in order to make control logic.Referring now to Fig. 7, block diagram is according to an embodiment of the invention shown, each side of cover type pedal structure shown in instruction diagram 4.Such as, in the embodiment of the present invention shown in Fig. 3 and Fig. 4, attaching parts 710 shown in Fig. 7 comprises arm 562 and is loaded with the connecting rod 572 of spring 574, and control piece 720 comprises switch 576 and control logic, this control logic is in order to the mode actuated clutches 545 similar with control piece 555 shown in Fig. 3, wherein the control logic of control piece 620 is in ETM pattern in response to sensing vehicle and in response to the actuating sensing switch 576, power-transfer clutch 545 is thrown off, and switch 576 activates due to chaufeur pressure pedal 560.(be in ICE pattern in response to sensing vehicle, the above-mentioned response of control logic 620 override, namely ignores the signal that pedal 560 has been depressed, thus logic does not cause the actuator of PXU power-transfer clutch 545 to make power-transfer clutch 545 move to disengaged position.Alternatively, moved to throw-out-of clutch position in response to sensing pedal 560, the control logic of control piece 620 causes the actuator of PXU power-transfer clutch 545 to make power-transfer clutch 545 move to disengaged position, and no matter vehicle is in ICE pattern or ETM pattern.)

Be described herein the structure being provided for dual-purpose pedal of clutch structure.Should understand from above, though the present invention especially favourable be due to ETM operation in ICE power-transfer clutch automatically throw off but for ETM operation and ICE operation all for pedal of clutch provides clutch position.Owing to being usually used in except pedal of clutch in ICE pattern with by engaging and throwing off ICE power-transfer clutch to engage and throw off ICE, also allow pedal of clutch to be used in by engaging and throwing off PXU power-transfer clutch to engage and throw off ETMG in ETM pattern, thus this is favourable.

In order to illustration purpose, provide the description to the embodiment of the present invention, but these embodiments be meant to be exhaustive or be used for the present invention to be limited to disclosed form.Many amendments and modification will be apparent for those of ordinary skill in the art.

Such as, refer again to the Fig. 3 about a modification, apposition has the connecting rod 520P being loaded with spring 550 second spring load can be placed on clutch pedal level 514 below pivot point 512, the load of this second spring load namely except the load of connecting rod 520, this load resistance is depressed the effect of pedal 212 by chaufeur and is attempted pedal 212 to be held in dead position.Spring 550 for connecting rod 520P is attempted more to be difficult to when making to be in ICE pattern depress pedal 212.But the spring 550 for connecting rod 520P only must be enough strong, to return to dead position by 212.If opposing chaufeur is this kind of subsidiary load of the application force of pressure pedal 212 is debatable, then also with spring 550, the alternative spring-like auxiliary hydraulic device operated can be relatively installed.This auxiliary device is controlled in response to indicating the switch of ICE pattern and ETM pattern, thus offset for the power of the spring 550 of connecting rod 520P when being in ICE pattern, to make when ICE pattern for the resistance of pressure power-transfer clutch 212 only with present in shown in Fig. 5, only for resistance that the attaching parts of ICE power-transfer clutch 206 is associated.In ETM pattern, as mentioned above, the attaching parts for ICE power-transfer clutch 206 is moved away from clutch pedal level 514 by actuator 412.Therefore, in ETM pattern, auxiliary device lost efficacy, thus was not cancelled for the power of the spring 545 of connecting rod 520P, made the spring 545 for connecting rod 520P after chaufeur depresses pedal 212, to make pedal 212 return to dead position thus.

Describe another modification about at this above Fig. 3, wherein the attaching parts of pedal of clutch 212 comprises connecting rod 520, and this connecting rod 520 certain some place at it in spherical or stem portion contacts with clutch pedal level 514.Connecting rod 520P contacts with clutch pedal level 514 at certain substantially the same some place, and be loaded with spring 550, thus when ETM pattern, even make after connecting rod 520 moves to ICE throw-out-of clutch position at actuator 412, clutch pedal level 514 is held in position same as shown in Figure 3 by spring 550 and connecting rod 520P, otherwise clutch pedal level 514 can be made to discharge from its clutch position.In the embodiment be connected to clutch pedal level 514 at connecting rod 520, making the motion of connecting rod 520 that clutch pedal level 514 must be made to move, connecting rod 520 or 522 automatically discharges from clutch arm 524 in ETM pattern, can under the condition not making clutch pedal level 514 move, make clutch arm 524 move to make actuator 412.

Referring now to Fig. 6 A, block representation is shown, this block diagram format illustrates the pedal of clutch 212 for vehicle of prior art, attaching parts 610 and power-transfer clutch 206.Be different from the control structure of the mechanical clutch 206 shown in Fig. 3, attaching parts 610 makes pedal of clutch 212 dock with control piece 630, and this control piece 630 can be such as hydraulic pressure, pneumatic or electric.Control piece 630 makes ICE power-transfer clutch 206 throw off in response to pedal of clutch 212 is moved to throw-out-of clutch position by chaufeur, and in response to chaufeur makes pedal of clutch be back to clutch position, ICE power-transfer clutch 206 is engaged.The motion of pedal of clutch 212 communicates with control piece 630 via attaching parts 610.

Referring now to Fig. 6 B, the block diagram format of one embodiment of the invention is shown, illustrates that apposition has ETMG power-transfer clutch 545 and control piece 640, and this control piece 640 can be such as hydraulic pressure, pneumatic or electric.Control piece 640 docks with existing control piece 630, and docks with the power-transfer clutch 545 of institute apposition.In response to the signal of instruction vehicle at ETM MODE of operation, control piece 640 automatically makes ICE power-transfer clutch 206 throw off.In addition, when being in ETM pattern, pedal of clutch 212 is optionally moved to throw-out-of clutch position in response to the pin of chaufeur and ETMG power-transfer clutch 545 is thrown off by control piece 640, and makes pedal of clutch 212 be back to clutch position in response to the pin of chaufeur and ETMG power-transfer clutch 545 is engaged.

Switch to the signal of ICE pattern in response to instruction vehicle, ICE power-transfer clutch 206 is discharged from being automatically held in disengaged position by control piece 640.In addition, be in ICE pattern in response to sensing vehicle, the above-mentioned response of control logic override of control piece 640, namely ignores the signal that pedal 212 has been depressed, thus logic does not cause the actuator of ETMG power-transfer clutch 545 to make power-transfer clutch 545 move to disengaged position.Alternatively, moved to throw-out-of clutch position in response to sensing pedal 212, the control logic of control piece 620 causes the actuator of ETMG power-transfer clutch 545 to make power-transfer clutch 545 move to disengaged position, and no matter vehicle is in ICE pattern or ETM pattern.

Consider another kind of alternative form, refer again to Fig. 5 A, block representation is shown, the pedal of clutch 212 of this prior art shown in block representation instruction diagram 1, attaching parts 610 and power-transfer clutch 206.With block diagram, another alternate embodiment of the present invention is shown in figure 5b, illustrates and be attached with attaching parts 615 and control piece 620, and this control piece 620 is placed between attaching parts 610 and ICE power-transfer clutch 206.Attaching parts 615 shown in Fig. 5 B comprises the connecting rod 520P being loaded with spring 550, and the control piece 620 shown in Fig. 5 B comprises for the actuator 412 of ICE power-transfer clutch 203 and switch 552, indicates the control logic 555 of carrying out communicating and the clutch actuator for power-transfer clutch 545 with ICE/ETM pattern.In this embodiment, actuator 412 being not interposing between original clutch pedal level 514 and clutch arm 524.In another embodiment of the invention, control piece 620 shown in Fig. 5 B can comprise and is placed in pneumatic, hydraulic pressure between original clutch pedal level 514 and clutch arm 524 or electrical control logic and device, thus in ICE pattern, control piece 620 is control clutch 206 in response to pedal of clutch 212, and in ETM pattern, control piece 620 in response to pedal of clutch 212 control clutch 545 and make power-transfer clutch 206 automatically keep throw off.

In alternative embodiments of the present invention, omit ETMG power-transfer clutch, and control piece and attaching parts are reequiped, to allow to use existing pedal of clutch (or existing pedal of clutch and cover type pedal), thus when shifting gears, make the controller of traction generator send signal, wherein this controller changes its response for accelerator pedal 213 in gearshift procedure.

A cross reference wherein and this with see the related application that is introduced into of mode in a kind of controller of ET system is described, this controller is from apposition in the button Received signal strength of the ICE hand gear gear box shifting bar of vehicle.According to one embodiment of the invention, provide except omitting ETMG power-transfer clutch 545 at this, be similar to the structure of structure shown in Fig. 3.According to this embodiment of the invention, the switch 552 that pedal of clutch 212 activates makes the gear shift of chaufeur be intended to be connected with the controller of ET system, instead of is undertaken by the button switch on gear-shift lever.Similarly, of the present invention have be similar in the embodiment of the structure of structure shown in Fig. 4 except omitting except power-transfer clutch 545, the switch 576 that pedal of clutch 560 activates is provided, be intended to make the gear shift of chaufeur be connected with the controller of ET system, instead of undertaken by the button switch on gear-shift lever.

When chaufeur prepare by pressure pedal of clutch 212 or 560 and actuation switch 552 or 576 and under ETM pattern, carry out gear shift time, he/her can make the controller of ET system send signal.Controller is by being in ETM pattern according to this controller or ICE pattern switches to " ETM gear shift " state or " ICE gear shift " state and in response to the signal from switch 552 or 576, arbitrary switching all can change the response of controller for vehicle accelerator pedal 213.This causes the performance comprising shift property of vehicle to carry out closer to traditional mode, and no matter whether apposition has ETMG and control piece and they thereof for the corresponding effect of vehicle.That is, when vehicle works in the ice mode, ETMG can be generating, or when vehicle is at ET MODE of operation, ETMG can be vehicle only have propelling source (as electrical motor).No matter which kind of mode of operation vehicle is in, controller is taken action in response to the chaufeur signal of the switch 552 or 576 activated from pedal of clutch, to make the performance of vehicle carry out in the mode closer to traditional IC E, this vehicle is the heavy-duty diesel oil lorry of such as 7 grades or 8 grades in one embodiment.

Or rather, in response to switch 552 or 576, controller weakens its response for accelerator pedal 213 position, make chaufeur have meticulousr control via accelerator pedal 213 for ETMG speed, and no matter ETMG carry out propelled vehicles as electrical motor or generate electricity as electrical generator again.Therefore, such as, when in ETM pattern during propelled vehicles, during pin pressure on operator lightly relief accelerator pedal 213, ETMG can reduce its speed more lentamente, the response of this more critically analog IC E.Similarly, because weakened accelerator pedal 213 responds, operator is also easy to the increase of more accurate control ETMG rotating speed.And when being in ICE pattern by ICE propelled vehicles, on operator lightly relief accelerator pedal 213 during pin pressure, ETMG can increase power generation torque more lentamente.

According to embodiments of the invention, there is other mode and change its response for accelerator pedal 213 to make controller.In one embodiment of this invention, controller changes its response, to eliminate the inertia of PXU and ETMG rotor on gearbox gear-shift gear and frictional influence.In order to understand this kind of object, consider that, when gear shift, hand gear gear case disconnects with ICE by making throw-out-of clutch, and by by gear box shifting to neutral gear, the output shaft of change speed gear box and wheel and change gear disconnect.This makes the change gear of change speed gear box to rotate freely.Like this, when gear shift, chaufeur usually makes the change gear coast of change speed gear box to lower RPM.Then, chaufeur is routinely by being made the shift collar motion selected carry out selected new change gear by gearbox gear-shift bar, wherein shift collar rotates with the speed corresponding with output shaft of gear-box and wheel.Then chaufeur starts this change gear is coordinated with shift collar.If change speed gear box has synchro, then this kind of cooperation comprises the synchro of the shift collar making to select and selected change gear frictional fit, before engaging with selected change gear with the tooth in selected shift collar, and beginning matching speed.In addition, chaufeur is engaging clutch lentamente, and controls by the accelerator pedal 213 of ICE the change gear speed that adjustment is selected further, to match with the speed of selected shift collar.

Be described further describing above see Fig. 8.If ETMG306 (Fig. 2) is energized, then this ETMG makes input shaft 125 rotate.Gear 802 is connected in input shaft 125 rigidly, and via gear 804, the rotation of input shaft 125 is passed to countershaft 806.Gear 820,822,824 and 825 is connected in countershaft 806 all rigidly, and all rotates together with the rotative speed of countershaft 806.Gear 820,822,824 and 825 all has different diameters, therefore when engaged to make another gear rotate time, the transmitting ratio that difference is possible is provided.Gear 826 is connected in gear 816 by idle gear 825 and for providing reverse gearwheel for vehicle.

Output shaft 129 is connected to axle drive shaft 230 and diff 316 (see Fig. 1), to drive wheel of vehicle, and therefore rotates with fixed relationship relative to wheel.Output shaft 129 is band keyways, and is directly connected in shift collar 830 and 832.Shift collar 830 and 832 is configured to laterally move, and rotates with the rotative speed identical with output shaft 129 simultaneously.Change gear 810,812,814 and 816 (being also called change gear 836 herein) always engages with their corresponding counter shaft gear 820,822,824 and 826 (being also called counter shaft gear 846 herein), and has the bearing that they can be rotated freely on output shaft 129.Shift collar 830 and 832 is connected in gear-shift lever (not shown), this gear-shift lever can operate by corresponding gear shift attaching parts, shift collar 830 and 832 to be moved, and one of them gear shift attaching parts is shown as gear shift attaching parts (or " bar ") 840 at this.Under the condition that shift collar 830 and 830 is located as shown in the figure, change speed gear box 204 (Fig. 2) is in " neutral gear ".At this kind of neutral state, if input shaft 125 is rotated by ETMG306, then the rotations such as all change gear 810 grades and counter shaft gear 820, and output shaft 129 keeps static (if wheel of vehicle is also static).That is, be in the condition of Neutral Position at gear-shift lever under, shift collar 830 and 832 does not engage with any one in change gear 810 etc., thus change gear 810 grade in response to ETS electrical motor 306 instead of wheel rotation and rotate, and shift collar 830 and 830 is in response to the rotation of wheel but not the rotation of ETS electrical motor 306 and rotating.

Shift collar 830 and 832 has " canine tooth " (such as, 827), and all change gears 810,812,814 and 816 have the coupling " hole " for engaging with canine tooth.Shift collar 830 and 832 is free to slide along axle 129 in response to the motion of gear-shift lever, makes one of them axle sleeve 830 or 832 and a position of engaging in change gear 810 etc. to move to.And shift collar 830 with 832 by axle sleeve 830 with 832 the spline coordinated with the keyway of axle 129 and being constrained to rotate together with axle 129.Change gear 810 etc. has the bearing that they can be rotated freely on output shaft 129.But when shift collar 830 or 832 coordinates with change gear (such as 812), change gear drives wheel by the spline driver output axle 129 connected with shift collar.The rotating speed of output shaft 129 is determined by the transmitting ratio of change gear (such as 812) and corresponding counter shaft gear (in this example, gear 822).Therefore, if selected gear 810, then for the rotating speed of given ETMG306, output shaft 129 is the slowest rotatably, and this is due to counter shaft gear 820 to 822 or 824 little, and change gear 810 is larger than change gear 812 or 814.

For given ETMG306 rotating speed, have to coordinate corresponding specific output shaft rotating speed with which change gear (810,812 or 814) with arbitrary shift collar 830 or 832.When change gear switches between change gear 810,812 or 814, the rotating speed of output shaft needs to match with the gear of corresponding " change to ".Remember, at neutral gear and when driving input shaft 125 by ETMG306, all not selected change gear 810 grades with by ETMG306 rotating speed and other the determined rotating speed of specific transmitting ratio, rotate freely on output shaft 129.Be in the condition of neutral gear at change speed gear box 122 under, shift collar 830 and 832 rotates with the speed of output shaft 129, and because wheel makes output shaft 129 rotate, thus the speed of output shaft 129 is directly associated with the speed of a motor vehicle.

If the rotating speed of output shaft 129 with by the next gear 810 etc. of " change to " does not match, then mating hole meeting " collision " in canine tooth 830 grade and next gear 810 grade, generation is called the phenomenon of " beating tooth ".(it is noted that in fact the wheel tooth of change gear 810 grade and corresponding counter shaft gear 820 etc. can't beat tooth, this is because all gears are all constantly meshed.)

Therefore, the problem of change gear is: shift collar 830 rotates with the speed identical with output shaft 129 with 832, and change gear (on output shaft) is to be rotated by the determined speed of specific transmitting ratio between drive shaft speed and counter shaft gear 820 etc. and change gear 810 etc.

In at least some embodiments, ETM pattern is the pattern of " not having power-transfer clutch ", to reduce equipment cost, and in downshift and braking procedure, optimize the ability that vehicle energy is recovered.Under the clutch conditions of throwing off not making ETM, manual transmission carries out gear shift and improves by using the synchro installing to shift collar (such as 830 and 832).Synchro is configured to: engaging canine tooth (such as 827) so that output shaft 129 is locked in next corresponding change gear (such as rigidly, 810,812 and 814) before, first utilize friction-driven part that shift collar is coordinated with next gear, this friction-driven part is used for by loss due to friction, the rotating speed of output shaft and ETM rotating speed (change gear) being matched.Although this can strengthen the ability of chaufeur gear shift, this can make cost increase and efficiency is reduced.

According to one embodiment of the invention, PXU304 is rotatably connected in the change gear of change speed gear box 204, and ETMG306 is connected in PXU.This affect change gear 836 when ICE power-transfer clutch 206 is thrown off and speed-change gear box is in neutral gear deceleration to the mode of lower RPM.That is, power shift gear can according to the specific inertia of PXU304 and ETMG306 and frictional behavior, due to PXU/ETMG more lentamente or more quickly deceleration.Therefore, in an embodiment of the present invention, control piece is configured by controller 312 to change the generation of ETMG desired signal, thus when pedal of clutch is in actuating (i.e. throw-out-of clutch) position, control piece 312 produces predetermined ETMG desired signal independent of the position of accelerator pedal 213, at this actuated position, predetermined ETMG desired signal is tending towards eliminating the inertia of PXU and ETMG on gearbox gear-shift bar and frictional influence.(term used herein " pedal of clutch " can refer to according to linguistic context cover type pedal of clutch, OEM pedal of clutch 212 or both.Do not exist in one of them above-described embodiment of cover type pedal 560 of the present invention, term " pedal of clutch " refers to OEM pedal 212.Such as in the embodiment that there is cover type pedal 560, and be at vehicle in the linguistic context of ICE pattern, if then herein with reference to artificial actuated clutches pedal, usually mean and make cover type pedal 560 move to actuated position.)

Be not, the required alternate variation ETMG desired signal of the predetermined ETMG desired signal that control piece produces independent of the position of accelerator pedal 213, and control piece produces this change ETMG desired signal in response to the position of accelerator pedal 213.But control piece can be configured to produce ETMG desired signal component, and by superposed on one another for these component of signals, to provide complete ETMG desired signal.That is, according to one embodiment of the invention, predetermined ETMG desired signal is the one-component of complete ETMG desired signal, and changes another component that ETMG desired signal is complete ETMG desired signal.

The predetermined ETMG desired signal being tending towards making the inertia of PXU and ETMG rotor and frictional influence to eliminate can be the signal being tending towards ETMG is worked as electrical motor (i.e. " electrical motor "), or is tending towards the signal that makes ETMG as generator operation.In other words, control piece is configured to predetermined inertia based on PXU and ETMG rotor and frictional behavior.Or rather, actuated position is in response to pedal of clutch, control piece produces predetermined ETMG desired signal, positive-torque is produced in order to make the electrical motor of ETMG, as long as designer carries out pre-structured based on following prediction to control piece: in some the time period processes after ICE throw-out-of clutch starts, the frictional influence of PXU and ETMG rotor tends to exceed inertia effect, produces clean frictional influence thus.In contrast, control piece produces predetermined ETMG desired signal, this signal is tending towards producing negative torque on ETMG, thus ETMG is generated electricity, as long as designer carries out pre-structured based on following prediction to control piece: in some the time period processes after ICE throw-out-of clutch starts, the inertia effect of PXU and ETMG rotor tends to exceed frictional influence, produces clean inertia effect thus.

Control piece is configured for producing the character of predetermined ETMG desired signal can based on the pre-determining of designer for the taxiing characteristics of PXU-ETMG rotor combination, and taxiing characteristics can be time behavior.Therefore, control piece can be configured to produce predetermined ETMG desired signal, thus when the clutch is disengaged, predetermined ETMG desired signal is i) fixing, ii) in time and change, iii) first fixingly then to change in time or iv) first change in time and then fix, wherein can change in time with set rate.In addition, the fixing and/or changing unit of predetermined ETMG desired signal in throw-out-of clutch process can after starting, continue throw-out-of clutch duration or lasting corresponding predetermined amount of time.

The taxiing characteristics of PXU-ETMG rotor combination can when this combination starts to slide, change based on the speed of a motor vehicle.Therefore, designer can pre-determine the relation between the initial skid speed of this combination and taxiing characteristics.Thus, control piece can be configured to comprise revolution counter or communicate with existing revolution counter (being also called speed gauge), and wherein revolution counter indicates the rotating speed of PXU-ETMG rotor combination directly or indirectly.Therefore, control piece pre-structured can be paired in corresponding different initial skid speed, produces different predetermined ETMG desired signals.

Alternatively, control piece can be configured in the process at least partially of PXU-ETMG rotor combination coasting time, dynamically determine the clean friction of this combination or clean inertial tendency, wherein in the process of at least coasting time section, the revolution counter in response to the rotating speed of instruction PXU-ETMG rotor combination is determined.According to this alternative, control piece is configured in response to clean friction or clean inertia effect, dynamically produces " making a reservation for " ETMG desired signal (namely, independent of the component of accelerator pedal 213 position in complete ETMG desired signal), and this only rubs or clean inertia effect self is dynamically determined by control piece.

In another embodiment of the present invention, even when comprising ETMG power-transfer clutch, controller as mentioned above in gearshift procedure, improve its response for accelerator pedal 213.

Referring now to Fig. 9, the structure of the conversion apparatus according to the embodiment of the present invention is shown, carries out working in double modes to allow power-transfer clutch 206.Structure shown in Fig. 9 allows to reequip the vehicle of original equipment manufacturers, to make user by the mode similar with aforementioned conversion apparatus, depress pedal 212 throw off to make the power-transfer clutch 206 of the original equipment manufacturers of Manual transmission 204 to throw off motion 922.Conversion apparatus shown in Fig. 9 also allows by the operation of actuator 412, power-transfer clutch 206 automatically to be thrown off, and the user of pedal of clutch 212 can not be interfered to move.This will be described in conjunction with Figure 10 and 11.But the following description of Fig. 9 explains how this kind of repacking structure makes actuator 412 keep substantially static, and can not interfere the operation of original equipment manufacturers.

Pedal of clutch 212 is attached to pedal travel transmitting assembly 910, and this pedal travel transmitting assembly comprises first section being fixed on pedal 212, second section 914 being fixed on portion's section 912 and is fixed on the 3rd section 916 of portion's section 914.The operator's compartment 902 being positioned at vehicle 202 at least partially of portion's section 912 is inner, and the pedal 212 being configured to make to be attached to one end is positioned at below the other end of portion's section 912, and the other end of portion's section 912 is attached to portion's section 914 at stationary pivot connecting portion 908 place, and this stationary pivot connecting portion 908 is the connecting portions being connected in the assembly 910 being fixed on vehicle 202 vehicle frame, and this assembly 910 is allowed to rotate in one plane.As shown in the figure, connecting portion 908 can be positioned at engine compartment 904 inside or can be positioned at operator's compartment 902 inner.

In order to position relative to pedal 212, connecting portion 908, connecting rod 930 and actuator 412 each several part of assembly 910, thus realize function described herein, the length of portion's section 912 and 914 and the length of portion's section 914 and 916 can form about right angle as shown in the figure according to the structure of vehicle 202, or can form other angle.Similarly, portion's section 912,914 and 916 can indicated by the structure by vehicle 202, there is length relative to each other or can have different proportion as shown in the figure.Should be appreciated that without the need to being shown to scale Fig. 9.

Connecting rod 930 is connected to portion's section 916 at one end by the pivotable of being caught by groove 918 and slide contact part 932, thus connecting rod 930 can rotate in one plane relative to pedal travel transmitting assembly 910, and can along the running lengthwise of groove 918.In shown structure, portion's section 916 bends backward towards pivot section 908.Portion's section 916 limits corresponding curved slot 918.This kind of structure can be provided in an embodiment of the present invention, this is that the sideway movement degree be tending towards when connecting portion 932 is slided up and down in groove 918 due to this structure is minimum, be tending towards the constant alignment keeping connecting rod 930 thus, and no matter this connecting rod is upward movement or moves downward.

Connecting rod 930 is configured to corresponding motion via pedal travel transmitting assembly 910 by the Movement transmit of pedal of clutch 212 to the mechanism's (not shown in fig .9) being used for making power-transfer clutch 206 (such as, see Fig. 3) to engage and throw off.This kind of mechanism is shown as clutch arm 524 in figure 3.(notice, the direction that the disengagement campaign of connecting rod 930 shown in Fig. 9 might not be identical along the disengagement campaign 534 with clutch arm 524 shown in Fig. 3.The disengagement campaign of connecting rod 930 shown in Fig. 9 is convertible into the different directions of the part as shown in the figure exceeding connecting rod 930.Or for the embodiment of power-transfer clutch 206 being applicable to Fig. 9, power-transfer clutch 206 can be configured in response to the disengagement campaign different from the disengagement campaign of clutch arm 524 shown in Fig. 3 and throw off.)

Pedal travel transmitting assembly 910 can by spring (not shown) be biased, make assembly 910 return to releasing position by spring, this releasing position is shown as clutch position 920 in fig .9.User's (chaufeur) can depress pedal 212, makes assembly 910 rotate around pivot section 908 thus.Under the condition that pedal 212 is depressed completely, assembly 910 moves to the clutch position 924 shown in Fig. 9.

Assembly 910 causes connecting rod 930 due to the pivotable of connecting portion 930 groove 918 and slip and upward movement as shown in the figure from the motion of 920 to position, position 924.This kind of motion of connecting rod 930 causes power-transfer clutch 206 to be thrown off.

Actuator 412 comprises cylinder body 933, and this cylinder body 933 can make extensible axle 542 passing in and out motion from the complete retracted position 940 shown in Fig. 9 in the position range of the complete extended position 942 shown in Figure 10.Cylinder body 933 connected by pivot section 938, and this pivot section 938 is namely fixed relative to the vehicle frame of vehicle 202 and allowed the connecting portion that cylinder body 933 rotates in one plane.

In the end relative with cylinder body 933, axle 542 limits groove 936, and the pivotable of connecting rod 930 and slide contact part are captured in this groove 936, thus cylinder body 933 can rotate in one plane relative to connecting rod 930, and can along the running lengthwise of groove 936.

Notice the above-mentioned structure shown in Fig. 9 and other details make connecting rod 930 can under there is not remarkable moving condition in actuator 412 upward movement (as previously mentioned, in response to the motion 922 causing assembly 910 to move to position 924 from position 920).Therefore, under the condition that actuator 412 is retracted, this does not depress pedal of clutch 212 and operates with the original manufacturer of holdback clutch 206 and interference with user.This is realized by shown structure at least in part, and its axis 542 is almost parallel to connecting rod 930, and connecting portion 934 can slide to the far-end of groove 936 near one end of cylinder body 933 from groove 936.

In certain embodiments, this is also partly because the width of groove 936 permitted, the width of this groove 936 makes the actuator 412 comprising axle 542 depart from the parallel alignment with connecting rod 930 to a certain extent, this is because pivotable and slide contact part 934 can move to opposite side from the side of groove 936, and can not cause axle 542 that remarkable motion occurs.In certain embodiments, this ability also partly owing to making the actuator 412 comprising axle 542 rotate around pivot section 938 allowed.

What should anticipate understanding is, be in the condition of retracted position 940 at axle 542 under, when pedal 212 is depressed (and assembly 910 is positioned at position 924 accordingly), this makes the bottom of groove 918 move to uppermost position, and this promotes connecting rod 930 via the bottom of connecting portion 932 again.In addition, actuator 412 is positioned at position 940 accordingly, thus this makes connecting portion 934 move to its top.Similarly, when pedal 212 is released (and assembly 910 is positioned at position 920 accordingly), this makes the bottom of groove 918 move to bottom position, and this makes connecting rod 930 decline via the bottom of connecting portion 932 again.In addition, actuator 412 is positioned at position 940 accordingly, thus this makes connecting portion 934 move to the bottom of axle 542.

Referring now to Figure 10 and 11, the operation of conversion apparatus according to Fig. 9 of the embodiment of the present invention is further described.Figure 10 illustrate this structure how do not make pedal of clutch 212 from the condition moved in its releasing position, power-transfer clutch 406 is thrown off by automatic actuater 412.Figure 11 illustrates mode that how this structure to make user and permitted by original equipment manufacturers with usual, pressure and release the clutch pedal 212, even when the axle 542 of actuator 412 extends.The combustion engine of vehicle and Manual transmission are disconnected automatically (in order to work in electric traction pattern) because this makes its axle 542 extend by actuator 412, thus power-transfer clutch 206 is thrown off, still allow chaufeur to be depressed and release the clutch pedal 212 by usual the permitted mode of original equipment manufacturers, thus this is useful simultaneously.

Figure 10 illustrates that pedal of clutch 212 is in releasing position (namely, pedal travel transmitting assembly 910 is in clutch position 920) and illustrate under the condition not affecting pedal of clutch 212, actuator 412 can be positioned at position 940 that axle 542 retracts or can be positioned at the position 942 that axle 542 extends completely.When axle 542 is in extended position 942, the situation that the bottom (namely, near the end of cylinder body 933) of groove 936 is in retracted position 940 than axle 542 extends get Geng Gao.In this position 942, connecting portion 934 by groove 936 bottom upwardly, and be fixed on connecting rod 930 due to connecting portion 934, force connecting rod 930 upwards.But, the slip of connecting portion 934 and pivotable character make connecting portion 934 can under the condition not making assembly 910 move, slide to the top of groove 918 (in portion's section 916).

Or rather, when axle 542 is retracted, connecting portion 934 is supported on connecting rod 930 by the bottom of groove 936, this makes the connecting portion 932 at connecting rod 930 top place be held in extreme lower position, in this extreme lower position, loosely seating is in the bottom of groove 918 for the bottom of connecting portion 932, and this groove 918 is arranged in portion's section 916 of assembly 910.And when axle 542 extends completely, connecting portion 934 is supported in higher position by the bottom of groove 936, this makes connecting portion 932 be held in extreme higher position, and in this extreme higher position, the top of connecting portion 932 is loosely pressed against the top of groove 918.

Figure 11 illustrates that actuator 412 is with the axle 542 being in complete extended position 942, and illustrate user can under not making actuator 412 or connecting rod 930 that the condition of significantly motion occurs, pressure and release the clutch pedal 212.This is due to as previously mentioned, in this position 942, connecting portion 934 by axle 542 middle slot 936 of actuator 412 bottom upwardly, thus connecting rod 930 is held in its uppermost position in fig-ure.Therefore, groove 918 make assembly 910 can under the interference condition not being subject to the connecting portion 932 be positioned on the top of connecting rod 930, move to the position 924 that pedal of clutch 212 is depressed, and move to the d/d position 920 of pedal of clutch 212.That is, the bottom (and assembly 910 is positioned at corresponding position 924) of groove 918 is slided under the condition that connecting portion 932 can be depressed at pedal of clutch, this is due to when assembly 910 is positioned at uppermost position 924, the bottom of portion's section 916 middle slot 918 is positioned at as upper/lower positions: the bottom of connecting portion 932 remains on this position by the bottom of complete outrigger shaft 542 middle slot 936, and the bottom of groove 936 is bearing on the connecting portion 934 on connecting rod 930.And connecting portion 932 can slide to the top (and assembly 910 is positioned at corresponding position 920) of groove 918 under the d/d condition of pedal of clutch, this is due to when assembly 910 is positioned at bottom position 920, the top of portion's section 916 middle slot 918 is positioned at as upper/lower positions: the top of connecting portion 932 remains on this position by the bottom of complete outrigger shaft 542 middle slot 936, and the bottom of groove 936 is bearing on the connecting portion 934 on connecting rod 930.
