Accompanying drawing explanation
Next the specific embodiment of the present invention is described in further detail combining accompanying drawing, wherein:
Fig. 1 is the double clutch gearbox OSS fault verification of embodiments of the invention
The flow chart of method.
Detailed description of the invention
With reference to Fig. 1, at the double clutch gearbox OSS fault verification of the present embodiment
In method, the signal used includes: detected by double clutch gearbox OSS
Double clutch gearbox output shaft tach signal ωoutp, double clutch gearbox power shaft rotating speed pass
The double clutch gearbox power shaft tach signal ω of sensor detectioninp, the driving wheel rotating speed of ABS pass
The first driving wheel tach signal ω that sensor is detectedwhl1With the second driving wheel tach signal ωwhl2, by sending out
The engine rotational speed signal ω that motivation speed probe is detectedengine。
First, it is determined that double clutch gearbox output shaft tach signal ωoutpDriving wheel rotating speed with ABS
The arithmetic mean of instantaneous value ω of signalwhlavgBetween difference whether be in tolerance in the range of.ωwhlavgPress
Calculate according to below equation:
ωwhlavg=(ωwhl1*K1+ωwhl2*K2)/2,
Wherein, K1It is the first driving wheel direction of rotation, K2It is the second driving wheel direction of rotation, K1Or K2Take
Value is that 1 expression vehicle advances, and value is-1 expression vehicle reverse, and value is that 0 expression direction cannot be sentenced
Not.Certainly, if if four-wheel drive or all-wheel drive, then the rotating speed of multiple driving wheel should be taken
Signal calculates arithmetic mean of instantaneous value.In theory, ωoutpWith ωwhlavgShould be equal, but due to assembling by mistake
The odjective causes such as difference, tire wear, it is allowed to both exist certain deviation, if at both differences
In the range of this tolerance, then it is assumed that ωoutpIt is rational, say, that double clutch gearbox is defeated
Go out shaft speed transducer fault-free.
If but ωoutpWith ωwhlavgDifference exceed tolerance scope, and difference exceedes permission
The persistent period of deviation range exceedes scheduled duration, and such as difference is more than 5rpm, and the time is more than 2s,
Then do not necessarily represent OSS and necessarily there occurs fault, therefore this phenomenon be likely to by
The own fault of driving wheel speed probe in ABS causes ωwhl1And ωwhl2Cannot detect or rotate
Direction cannot differentiate causes K1Or K2It is 0 and produces, the most should not send fault message, and answer
When to ωoutpVerify further.
Work as ωoutpWith ωwhlavgDifference exceed tolerance scope, and difference exceedes tolerance model
When the persistent period enclosed exceedes scheduled duration, determine whether ωinp=ωoutp*igearWhether set up, wherein
igearFor the resultant gear ratio of residing gear during double clutch gearbox stable drive.At double clutch gearbox
When being in a certain gear stable drive, resultant gear ratio i of this geargearIt it is a definite value, although clutch
Driving disc spacing pressing and the clutch plate speed discrepancy of sliding rub rate, i.e. clutch is there is between driving disc spacing pressing and the clutch plate of device
With the ratio of driving disc spacing pressing rotating speed, sliding rate of rubbing is the biggest, and to represent the speed discrepancy at double clutch two ends the biggest, but
During variator stable drive, the master and slave Moving plate of double clutch is closely to compress, and can be approximately considered and turn
Speed difference is zero, and i.e. sliding the rate of rubbing is zero.If it is to say, now ωinp=ωoutp*igearSet up, then demonstrate,prove
Bright ωoutpBe correct, i.e. double clutch gearbox OSS does not breaks down, and should not
Send fault message.
But work as ωinp=ωoutp*igearWhen being false, the most not can determine that double clutch gearbox output shaft
Speed probe fault, because being now likely to be the event of double clutch gearbox power shaft speed probe
Barrier causes ωinpValue inaccurate or disappearance, now should be to ωoutpVerify further.
Work as ωinp=ωoutp*igearWhen being false, it is judged that ωengine=ωoutp*igearWhether set up.It is similar to above
Describe, when stable drive, engine speed can be approximately considered and input with double clutch gearbox
Speed discrepancy between axle rotating speed is zero, and resultant gear ratio i of now residing geargearIt is a definite value,
Therefore ωengine=ωoutp*igearSet up, then prove ωoutpCorrect, i.e. double clutch gearbox output
Shaft speed transducer does not breaks down, and should not send fault message.
Only work as ωengine=ωoutp*igearWhen being false, i.e. double clutch gearbox output shaft tach signal
With the arithmetic mean of instantaneous value of driving wheel tach signal of ABS, double clutch gearbox power shaft tach signal,
When engine rotational speed signal is the most unreasonable after carrying out triple verification, the diagnostic system of TCU just send double
Clutch transmission OSS fault-signal, and the situation of wrong report of breaking down must be
The driving wheel rotary speed signal sensor of ABS, double clutch gearbox power shaft speed probe, start
Machine rotary speed signal sensor simultaneous faults, the probability that this situation occurs is the least, therefore fault
Rate of false alarm is greatly diminished.
The fault-signal driving malfunction lamp flicker that the diagnostic system of TCU is sent, reminds driver as early as possible
Enter maintenance station to overhaul, prevent potential driving risk.Further, fault-signal is stored in TCU
Internal memory in form fault message log file, maintainer can read this log file, and it is fixed to help
Position failure problems point, improves gearbox repairing efficiency.
Although the present invention combines above example and is described, but the present invention is not limited to
Stating embodiment, and only limited by claim, those of ordinary skill in the art can be easily to it
Modify and change, but and without departing from the essential idea of the present invention and scope.
