Description
Technical field
The present invention relates to automotive transmission control field, be specifically related to the controlling method of double-clutch automatic gearbox limp-home.
Background technique
Double-clutch automatic gearbox comprises two coaxial nested or clutches of being arranged in parallel, coaxially, the interior input shaft of inside and outside nested arrangement and outer input shaft, output shaft, is arranged in the multiple synchromesh gears on output shaft, multiple selector fork and 1 differential mechanism composition.Speed changer is strange, even number gear driving gear is arranged on inside and outside input shaft, by switching and the action of different synchronizer of two clutches, realizes torque conversion and output.
Limp-home function refers at speed changer and occurs that damaging appears in some component, cannot complete normal use function, but can also realize within the specific limits the output of vehicle power, can utilize a part of component that current function is intact to complete the function of speed changer.
When driving, electronic control unit (ECU) thus the signal that need to obtain by various sensors the different groups such as engine rotational speed signal, engine torque signal, vehicle speed signal, shift signal, accelerator open degree signal double-clutch automatic gearbox is controlled and is realized self shifter.With reference to figure 1, taking wet-type double-clutch automatic speed-change device as example, realizing automatic gear change function needs automatic transmission case control unit (TCU) to gather different signals by the sensor of automatic transmission inside, wherein to gather clutch input speed signal (be clutch driving plate rotating speed to clutch rotational speed sensor 1, generally equal engine speed), OSS 2 gathers the tach signal of the first output shaft 13, the tach signal of input shaft 11 in interior input shaft rotating speed sensor 3 gathers, outer input shaft rotating speed sensor 4 gathers the tach signal of outer input shaft 12, 2/6 gear shift fork position transducer 5, 5/N gear shift fork position transducer 6, 3/1 gear shift fork position transducer 7, R/4 gear shift fork position transducer 8 gathers respectively four selector fork position signals, first clutch pressure transducer 9 gathers first clutch pressure signal, second clutch pressure transducer 10 gathers second clutch pressure signal, also there is the second output shaft 14 in the double clutch in Fig. 1, certainly also can speed probe be set for this output shaft 14.But at some in particular cases, for example in motion frequent start-stop or switch gear, can cause the overheated selector fork position transducer 5 that makes of signal emitter of double-clutch automatic gearbox inside, 6, 7, 8 all lost efficacy, or because the reasons such as line fault cause selector fork position transducer 5, 6, 7, 8 all lost efficacy, although it is still normal that the machinery of double-clutch automatic gearbox is carried out function, but now TCU is owing to cannot judging selector fork present position, cannot proceed the control of automatic transmission and make car load enter fault mode, throw-out-of clutch runs out of steam and stall or parking suddenly car load, and in the time that after a period of time, sensor temperature decline is worked again, after TCU picked up signal, controlling again automatic transmission resumes work, car load accelerates suddenly, and fall off when driving, it is very dangerous stopping or accelerating, especially in the time of running on expressway.
The control logic of existing double-clutch automatic transmission limp-home as shown in Figure 2, when interior input shaft or outside in input shaft rotating speed sensor one break down and another one when still normal, control vehicle stop, then controlling gearshift travels odd even gear simultaneously at gear, and detection based on normal sensor exports to calculate the corresponding input shaft rotating speed of abnormal sensor, thereby realize limp-home function.But first the prerequisite that realizes of the method is still to have one can normally work in two input shaft rotating speed sensors, in the time that whole group of input shaft rotating speed sensor is all abnormal, cannot realize limp-home function; Secondly, the method still needs to stop and carries out gear switching, and this remains very dangerous when driving; Again, the method can only be travelled with the gear of setting, and cannot carry out normal gear switching, but when road conditions complexity, or in the time of running on expressway, must carry out gear smoothly and switch guarantee safety.
Summary of the invention
When the object of the invention is to solve selector fork position signal and all losing, vehicle is fallen off, is stopped and threatens safe problem, ensures that vehicle still can limp-home under Parking condition not, and embodiments of the invention provide following technological scheme for this reason:
A kind of double-clutch automatic gearbox limp-home controlling method, comprising: gather vehicle speed signal, clutch input speed signal, interior input shaft rotating speed signal, outer input shaft rotating speed signal, output shaft tach signal, selector fork position signal; In the time that described selector fork position signal is all lost, whether mate according to the speed ratio verification current shift of described vehicle speed signal, described clutch input speed signal and current shift; If current shift coupling, keeps current shift to travel, if current shift is not mated, carry out the switching of odd even gear.
Preferably, when described selector fork position signal all lose occur in that gear switches or clutch handoff procedure in time, first carry out gearshift according to default pressure and move and complete clutch and switch and move.
Preferably, described odd even gear switch step comprises: keep the engagement of current shift gear pair; Promote target gear selector fork according to default pressure; Whether correctly judge according to the speed ratio of described interior input shaft rotating speed signal, described outer input shaft rotating speed signal whether described selector fork is correctly hung into target gear; If selector fork is correctly hung into target gear, carry out clutch and switch action.
Preferably, if selector fork is not correctly hung into target gear, carry out and move back gear action, then again promote selector fork, correctly do not hang yet into target gear, throw-out-of clutch when promotion selector fork number of times reaches predetermined value.
Preferably, selector fork is correctly hung into target gear, and completes after clutch switching action, again judges that whether the speed ratio of described interior input shaft rotating speed signal, described outer input shaft rotating speed signal is correct.
In the present invention, even if selector fork position signal is all lost, but owing to having increased the step of utilizing vehicle speed signal, clutch input speed signal and current shift place speed ratio to carry out verification, therefore under the condition of current shift coupling, still can keep current shift normally to travel, and needn't holdback clutch, can not cause and fall off or stop, improve travel safety.
Further, even if current shift is not mated, need to carry out gear switching, now keep the engagement of current shift gear pair, using the input shaft rotating speed at the driving gear place of current shift as with reference to value, promote selector fork with default pressure, although now because selector fork position signal loss cannot judge selector fork present position, but still can obtain the driving gear place input shaft rotating speed of target gear, by the rotating ratio of two input shafts, can indirectly judge whether selector fork has correctly been switched to target gear, that is to say, under the normal condition of mechanical function, the present invention still can obtain the information whether selector fork correctly switches indirectly, thereby continue to carry out the switching action of clutch, can the in the situation that of limp-home, realize normal gearshift function.
Further, in the time that the whole loss of selector fork position signal occur in gear switching or clutch handoff procedure, first carry out gearshift according to default pressure and move and complete clutch and switch action, can ensure that follow-up current shift matching verification proceeds also can obtain correct speed reference.
Further, if selector fork cannot correctly be switched to target gear, move back after gear and again attempt switching improving chance of success, and reach after pre-determined number still incorrect, the mechanical actuating mechanism that proves automatic transmission goes wrong, and now just holdback clutch is rational.
Further, selector fork is correctly hung into target gear, and completes after clutch switching action, now target gear has become current shift, again carry out verification, improved safety redundancy, can ensure that gearshift action is performed until reach correct gear always.

With reference to figure 1, in wet-type double-clutch automatic speed-change device, pressurize to realize clutch by oil pump (pump) to two clutches and switch.Clutch rotational speed sensor 1 gathers clutch input speed signal (being clutch driving plate rotating speed), first clutch pressure transducer 9 gathers first clutch pressure signal, second clutch pressure transducer 10 gathers second clutch pressure signal, interior input shaft 11 is connected with first clutch, and outer input shaft 12 is connected with second clutch.On input shaft 11, be furnished with outside 1 gear driving gear and 3 gear driving gears, on interior input shaft, be furnished with 2 gear driving gears and 4 gear driving gears, wherein 3 gear driving gears are simultaneously as 5 gear driving gears, 4 gear driving gears are simultaneously as 6 gear driving gears, 2 gear driving gears are simultaneously as reversing gear driving gear, like this, odd number gear driving gear is all arranged on interior input shaft 11, and even number gear driving gear is all arranged on outer input shaft 12.On the first output shaft 13, be furnished with parking ratchet wheel (park lock), 5 gear driven gears (5TH), 6 gear driven gears (6TH) and 2 gear driven gears (2ND), on the second output shaft 14, be furnished with 1 gear driven gear (1ST), 3 gear driven gears (3RD), 4 gear driven gear (4TH) and the driven gears that reverse gear (REV).The gear pair engagement of the switching by first clutch and second clutch and each driving gear, driven gear, realizes power output through differential mechanism (differential).OSS 2 gathers the tach signal of the first output shaft 13, the tach signal of input shaft 11 in interior input shaft rotating speed sensor 3 gathers, outer input shaft rotating speed sensor 4 gathers the tach signal of outer input shaft 12, and 2/6 gear shift fork position transducer 5,5/N gear shift fork position transducer 6,3/1 gear shift fork position transducer 7, R/4 gear shift fork position transducer 8 gather respectively four selector fork positions.
With reference to figure 3, when driving, ECU can constantly gather vehicle speed signal, accelerator open degree signal etc., the clutch input speed signal being gathered by TCU, interior input shaft rotating speed signal, outer input shaft rotating speed signal, output shaft tach signal, selector fork position signal also can pass to ECU, and ECU can send instruction to TCU according to collected signal, TCU controls the switching of each selector fork action, first clutch and second clutch.
In the time of no signal fault, vehicle can normally travel, once and occur signal fault, first judge whether because the whole faults of shift fork position transducer 5,6,7,8 cause selector fork position all to be lost, if otherwise taked example other control measure as described in the background art, if yes then enter subsequent step.
If selector fork position signal is all lost, TCU cannot obtain selector fork position, but TCU can record the data of current shift always, due under a certain gear, relation between the speed ratio (velocity ratio) of the speed of a motor vehicle, engine speed and this gear determines, the relation of each gear velocity ratio of the vehicle of for example certain double-clutch automatic gearbox and engine speed, the speed of a motor vehicle is as shown in table 1.

And in the ordinary course of things, clutch input speed equals engine speed, whether the clutch input speed signal therefore, gathering according to vehicle speed signal, clutch rotational speed sensor 1 and the speed ratio at current shift place (being velocity ratio) just can verification current shift mate.For example in 3 gear running process, selector fork position signal is all lost, now to be recorded to current shift be 3 gears to TCU, corresponding speed ratio is 1.478, clutch rotational speed sensor 1 collects engine speed (clutch input speed signal) for 2500rpm, the vehicle speed signal that ECU obtains is 51 kilometers/hour, can prove current 3 gear couplings, otherwise 3 gears do not mate.
If current shift coupling, keeps current shift to travel, need not stop, ensure safety.
If current shift is not mated, for example accelerator open degree becomes large and engine speed improves, and causes 3 gears not mate, and need to carry out follow-up odd even gear and switch.
Certainly, because there is the process of putting into gear in advance with clutch switching in double-clutch automatic gearbox, if selector fork position signal is all lost while occurring in gear switching or clutch handoff procedure, first carry out gearshift according to default pressure and move and complete clutch switching action, thereby automatic transmission is reached at gear travelling state, and this is favourable to follow-up verification.Default pressure is the pressure of the factory-designed promotion selector fork action of automatic transmission or promotes the pressure that clutch switches.
As shown in the dotted line frame of Fig. 3, switch in order to carry out odd even gear, need to first keep the engagement of current shift gear pair, then promote target gear selector fork according to default pressure, if switching, target gear selector fork puts in place, odd number gear and even number gear respectively have a gear at gear, the interior input shaft rotating speed signal collecting according to interior input shaft rotating speed sensor 3, whether the speed ratio of the outer input shaft rotating speed signal that outer input shaft rotating speed sensor 4 collects correctly just can judge whether selector fork is correctly hung into target gear, if selector fork is correctly hung into target gear, carry out clutch and switch action.Still taking current shift as 3 gears for example, because accelerator open degree becomes large, engine speed improves, and 3 gears need to switch to 4 gears, but now because R/4 gear shift fork position transducer 8 faults make TCU cannot judge selector fork particular location.Now in order to realize gearshift, still keep 3 gear driving gears to engage with the gear pair of 3 gear driven gears, do not carry out clutch and switch, interior input shaft rotating speed sensor 3 obtains interior input shaft rotating speed signal as with reference to value, then promotes 4 gear selector forks with default pressure.If being pushed, 4 gear selector forks put in place, now on the second output shaft 14 3 gear, 4 gears are simultaneously at gear, interior input shaft 11 is through 3 gear driving gears, 3 gear driven gears, the second output shaft 14, 4 gear driven gears and 4 gear driving gears drive outer input shaft 12 to dally, can obtain outer input shaft rotating speed signal by outer input shaft rotating speed sensor 4, so just can calculate the speed ratio between current interior input shaft 11 and outer input shaft 12, in supposing, input shaft rotating speed is N1, outer input shaft rotating speed is N2, the 3 gear driving gear numbers of teeth are Z1, the 3 gear driven gear numbers of teeth are Z2, the 4 gear driving gear numbers of teeth are Z3, the 4 gear driven gear numbers of teeth are Z4, N1:N2=Z2/Z1:Z4/Z3, that is to say that speed ratio only depends on 3, the number of teeth of 4 gear driving gears and driven gear, the number of teeth is constant, so 3, 4 gears are determined at the speed ratio of gear simultaneously, whether the speed ratio gathering by judgement is like this correct, just can judge whether 4 gear selector forks are correctly hung into 4 gears.
If selector fork is correctly hung into 4 gears, first clutch starts to throw off, and second clutch starts engagement, completes clutch and switches.After this vehicle can normally travel with 4 gears.
It is similar that other odd even gear switching mode and 3 gears change 4 gears, no longer describes in detail.
If speed ratio is incorrect, mean that selector fork does not correctly switch, now prove to have mechanical failure or other logic fault, first carry out and move back gear action according to default pressure, then again promote selector fork and again shift gears, and TCU records once-through operation, still have the possibility of correct switching through attempting selector fork, now still needn't stop, only have when promotion selector fork number of times reaches predetermined value and correctly do not hang yet into target gear, throw-out-of clutch, car load runs out of steam.
As preferred version, correctly hang into target gear at selector fork, and complete after clutch switching action, again whether correct according to the speed ratio of interior input shaft rotating speed signal, outer input shaft rotating speed signal, judge that whether current shift is correct.
Visible from the above description, in whole control procedure, although shift fork position signal is all lost, but still can carry out safely gearshift action, in limp-home process, needn't stop or Reduced Speed Now.
Although the present invention is described in conjunction with above embodiment, but the present invention is not limited to above-described embodiment, and being only subject to the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present invention and scope.
