Clutch is in pre- bonding state.At this point it is possible to which even number clutch is set as first clutch, even number clutch is set as
Second clutch, and real-time detection odd number clutch whether there is catching phenomenon.
In specific implementation, when detecting driver's step on the accelerator, it is possible to determine that receive driver's input
Torque demand instruction.In the torque demand instruction for receiving driver's input, can calculate corresponding with torque demand instruction
Clutch target torque requirements.
After calculating clutch target torque requirements, the actual transfer torque value of available first clutch,
Namely the torque of first clutch engine output when being in bonding state.By actual torque delivery value and clutch target torque
Requirements subtract each other, when the difference between the two is all larger than preset first threshold value in default first duration, it is possible to determine that first clutch
There are catching phenomena.
In specific implementation, the first duration and first threshold can be according to actual application scenarios sets itselfs.In
In one embodiment of the invention, first when a length of 400ms, first threshold is 30 Newton meters (Nm).In other embodiments of the present invention,
First duration and first threshold may be other values, be not repeated herein.
In embodiments of the present invention, determining first clutch, there are after catching phenomenon, it is understood that there may be the following two kinds situation:
1) first clutch is stuck, can not work normally；2) there are slight catching phenomena for wrong report or first clutch, but not right
The working condition of first clutch has an impact.Therefore, step can be executed there are after catching phenomenon in judgement first clutch
Rapid S102；When detecting that catching phenomenon is not present in the first clutch in double-clutch speed changer, then step can be continued to execute
S101, namely first clutch is continued to test with the presence or absence of catching phenomenon.
Step S102 determines the first clutch with the presence or absence of Block failure.
In specific implementation, detecting that first clutch there are after catching phenomenon, can first determine first clutch
With the presence or absence of Block failure, first clutch is caused to can not work normally.
In specific implementation, detect first clutch there are after catching phenomenon, can with preset detection cycle,
Periodically motion control instruction is sent to first clutch.First clutch, can be with after receiving motion control instruction
Moved back and forth between preset first position and the second position, in which: first position be double-clutch speed changer driving disc spacing pressing with
The distance between driven disc is greater than the corresponding position of first distance, and the second position is the driving disc spacing pressing and driven disc of double-clutch speed changer
The distance between be less than the corresponding position of second distance, and first distance be greater than second distance.
In embodiments of the present invention, first position can be with are as follows: using the driving disc spacing pressing of double clutch as origin, when driven disc and master
The distance of Moving plate is equal to S1The corresponding position of product between default first coefficient, S1Driven disc and active for double clutch
Maximum distance between disk, the first coefficient can be configured according to actual needs.In embodiments of the present invention, the first coefficient can
Think 80%~95%.
In embodiments of the present invention, the second position can be with are as follows: using the driving disc spacing pressing of double clutch as origin, when driven disc and master
The distance between Moving plate is equal to S1The corresponding position of product between default second coefficient, the second coefficient can be according to practical need
It is configured, and the second coefficient is less than the first coefficient.In embodiments of the present invention, the second coefficient can be 5%~20%.
It is understood that the first coefficient can be set according to actual needs with the second coefficient, it is not limited in
The numerical value provided in the above embodiment of the present invention.
It, can be with the displacement of real-time detection first clutch in each detection cycle.In a detection cycle, detection
When being unable to reach first position in default second duration to the position of first clutch, it is possible to determine that first clutch has card
Stagnant failure.In a detection cycle, detect that the position of first clutch is unable to reach second in default third duration
When position, it also can be determined that there are Block failures for first clutch.
That is, in each detection cycle, it can be determined that first clutch is during moving back and forth, if energy
Enough reach first position, and judges whether the position of first clutch can reach the second position.If in a detection cycle
Interior, first clutch is unable to reach first position or first clutch in the mistake moved back and forth during moving back and forth
When being unable to reach the second position in journey, that is, it can determine that there are Block failures for first clutch.Correspondingly, if in a detection cycle
It is interior, when first clutch is unable to reach first position during moving back and forth and is unable to reach the second position, it can also sentence
Determining first clutch, there are Block failures.
Above-mentioned judgement first clutch whether there is the principle of Block failure are as follows: when first clutch is completely stuck, In
When control first clutch moves back and forth, since first clutch may be completely stuck, first clutch is possibly can not
It is mobile, therefore first clutch can not move to the second position from first position in a detection cycle.Therefore, when first from
Clutch can not can determine that first clutch has card in a detection cycle, when moving to the second position from first position
Stagnant failure.
Step S103, when determining the first clutch, there are when Block failure, control the first clutch respective shaft
On shift fork be disengaged to middle position, and control second clutch combination, to continue to output power.
In specific implementation, when determining first clutch, there are after Block failure, that is, can determine that first clutch is current
It may can not work normally.For ensure vehicle can normally travel, can be sent to first clutch and be detached from control instruction, to the
Two clutches, which are sent, combines control instruction.Shift fork in respective shaft is disengaged to by first clutch after receiving control instruction
Middle position is switched to pre- bonding state from bonding state.Second clutch is after receiving in conjunction with control instruction, from advance in conjunction with shape
State is switched to bonding state.At this point, engine can continue through second clutch output torque, so as to drive vehicle after
It continues and sails.
In the prior art, when first clutch is there are when Block failure, if driver switches gear at this time, it is possible to meeting
The case where causing first clutch to be combined with second clutch.When there is above situation, control first clutch with
Second clutch is detached from, until starting vehicle next time.At this point, vehicle may be in non-power state for a long time, it may
It will lead to the case where seriously affecting the safety of the vehicle driving generation such as knock into the back.
And in embodiments of the present invention, when determining the first clutch for being currently at bonding state in double-clutch speed changer
There are when Block failure, the shift fork controlled in first clutch respective shaft is disengaged to middle position, and control second clutch combine with
Power is continued to output, to avoid power output interruption, so as to avoid because first clutch is there are when clamping stagnation, second clutch
Combination cause two clutches in combination with the case where appearance, and then can to avoid vehicle for a long time be in non-power state,
Therefore the safety of vehicle driving can be improved.
In specific implementation, when determining first clutch, there are after Block failure, be quickly and easily by first clutch
It is detached from, moment of torsion control instruction can be sent to engine.Engine, can be by output torque after receiving moment of torsion control instruction
Value is switched to default first output torque value from current output torque value, and current output torque value is greater than the first output torque
Value.
That is, reducing current output there are when Block failure, can first control engine when determining first clutch
Torque value, so that first clutch can rapidly switch from bonding state.
After second clutch combination, torque can be sent to engine and restore instruction.Engine is receiving torque
After restoring instruction, output torque value can be reverted to the output torque value before switching, to guarantee to meet driver's
Drive demand.
For example, engine current output torque value is A.First clutch is being determined there are after Block failure, to engine
Moment of torsion control instruction is sent, engine current output torque value is controlled from A and is reduced to B, A > B.After second clutch combination,
Torque is sent to engine and restores instruction, and the output torque for controlling engine reverts to A from B again.
In practical applications, first clutch may be simply due to mechanical breakdown, it is possible that card within certain a period of time
Stagnant failure.With the traveling of vehicle, it may restore normal there are after Block failure.Therefore, in the embodiment of the present invention
In, first clutch can be determined in multiple detection cycles with the presence or absence of Block failure, with this in this driving procedure
To determine number of the first clutch there are Block failure.
From in the above embodiment of the present invention it is found that determining that the first clutch, can be according to preset there are after catching phenomenon
Detection cycle, timing controlled first clutch move back and forth between the first location and the second location.In each detection cycle
In, if detecting, first clutch is unable to reach first position in the second duration, or is unable to reach second in third duration
Position, or when being unable to reach first position in the second duration and being unable to reach the second position in third duration, it is possible to determine that
In the current detection period, there are Block failures for first clutch.
In specific implementation, it in a driving procedure, can be deposited in multiple detection cycles, namely to first clutch
Whether Block failure is repeatedly confirmed.In a driving procedure, can recording first clutch in real time, there are clamping stagnation events
The number of barrier.When first clutch there are the number of Block failure reach preset first time it is several when, it is possible to determine that the first clutch
Device is completely stuck, can not work normally.Motion control instruction, Ye Jiting are sent to first clutch at this point it is possible to control stopping
Only control first clutch moves back and forth between the first location and the second location.
In practical applications, first number can be set according to actual needs.In specific implementation, first number is big
In 2 times.In an embodiment of the present invention, first number is set as 3 times.In an alternative embodiment of the invention, first number setting
It is 5 times.
After stopping sending motion control instruction to first clutch, clutch grab error code can be generated, and will give birth to
At clutch grab error code save.
