Abstract
A kind of detection and countermeasure of the unexpected movement of clutch actuating mechanism, comprising the following steps: real-time monitoring is carried out to the order of clutch and state in the case where clutch is kept completely separate (in conjunction with) state；In the case where vehicle condition meets, when clutch command is in the state for keeping separating (in conjunction with), but when clutch virtual condition changes, then judge that unexpected combination (separation) occurs in clutch actuating mechanism, into pre- malfunction, and it is immediately disconnected (in conjunction with) clutch, while counting to the number of stoppages, if recurring repeatedly, failure is made a definite diagnosis；After failure is made a definite diagnosis, current gear is kept, forces to combine (separation) clutch, make the return trip empty shelves automatically after parking, shows failure, on vehicular meter to remind driver to repair to service station in time.Not only fault detection method is simple by the design, accuracy is high, failure countermeasure high reliablity, and improves the security performance of vehicle.
Description
Technical field
The present invention relates to technical field of automobile design more particularly to a kind of detections of the unexpected movement of clutch actuating mechanism
And countermeasure, be primarily adapted for use in detection and reply the unexpected combination of clutch actuating mechanism with separate.
Background technique
With the development of automatic transmission technology, electric control mechanical type automatic speed variator (AMT) is since its structure is simple, transmission
The features such as high-efficient, at low cost, have become an important development direction of automatic transmission, and the automobile for carrying AMT is protected
The amount of having grows steadily year by year.The key technology of research and development AMT automatic transmission is the automatic control of itself clutch, AMT from
The control precision and performance of clutch directly affect the starting of AMT automatic transmission working performance or even vehicle, gear shifting quality.Driving
In the process, when clutch actuating mechanism unexpected separating action occurs due to failure problems, if will lead to without protection
The even ablation of clutch sliding wear, badly damaged life of clutch；In gearshift procedure, when clutch actuating mechanism is due to failure cause
When there is unexpected combination movement, gearbox can be damaged, consequence is serious.
Summary of the invention
The purpose of the present invention is overcome fault detection method existing in the prior art complicated, fault-free countermeasure scarce
It falls into and problem, provides that a kind of fault detection method is simple, fault detection method accuracy is high, failure countermeasure high reliablity
The detection and countermeasure of the unexpected movement of clutch actuating mechanism.
In order to achieve the above object, the technical solution of the invention is as follows: a kind of unexpected movement of clutch actuating mechanism
Detection and countermeasure, method includes the following steps:
A, real-time monitoring is carried out to the order of clutch and state in the case where clutch is kept completely separate state；It is completely combined in clutch
Real-time monitoring is carried out to the order of clutch and state under state；
B, in the case where vehicle condition meets, when clutch command is in the state for keeping isolated, but clutch virtual condition
When changing, then judge that unexpected combination occurs in clutch actuating mechanism, into pre- malfunction, and be immediately disconnected from
Clutch, while the number of stoppages is counted, if recurring repeatedly, make a definite diagnosis failure；In the case where vehicle condition meets,
When clutch command is in the state for keeping combining, but clutch virtual condition changes, then judge that clutch executes machine
There is unexpected separation in structure, into pre- malfunction, and combines clutch immediately, while counting to the number of stoppages,
If recurring repeatedly, failure is made a definite diagnosis；
C, failure is shown, on vehicular meter to remind driver to repair in time to service station.
In step B, when the unexpected combination of clutch actuating mechanism recurs number more than or equal to 3 times, then event is made a definite diagnosis
Barrier.
In step C, after the unexpected combination failure of clutch actuating mechanism is made a definite diagnosis, keep current gear, force combine from
Clutch, make the return trip empty shelves automatically after parking.
In step B, when the unexpected separation of clutch actuating mechanism recurs number more than or equal to 3 times, then event is made a definite diagnosis
Barrier.
In step C, after the unexpected separation failure of clutch actuating mechanism is made a definite diagnosis, keep current gear, force separation from
Clutch, make the return trip empty shelves automatically after parking.
In step A, by installing clutch position sensor, the present bit of real-time monitoring clutch in automatic gear-box
It sets, to determine clutch real-time status.
The clutch actuating mechanism is pneumatic clutch executing agency.
Compared with prior art, the invention has the benefit that
1, it is protected in the present invention a kind of detection and countermeasure of the unexpected movement of clutch actuating mechanism when clutch command is in
The state of separation is held, but when clutch virtual condition changes, then judges that unexpected knot occurs in clutch actuating mechanism
It closes, into pre- malfunction, and is immediately disconnected clutch, while counting to the number of stoppages, if recurring repeatedly, really
Examine failure；When clutch command is in the state for keeping combining, but clutch virtual condition changes, then clutch is judged
There is unexpected separation in executing agency, into pre- malfunction, and combines clutch immediately, while carrying out to the number of stoppages
It counts, if recurring repeatedly, makes a definite diagnosis failure；After failure is made a definite diagnosis, failure is shown on vehicular meter, with remind driver and
When repaired to service station；Above-mentioned design not only makes that fault detection method is simple, accuracy is high, but also makes failure countermeasure
High reliablity.Therefore, fault detection method of the present invention is simple, accuracy is high, and failure countermeasure high reliablity.
2, by fluid drive in the present invention a kind of detection and countermeasure of the unexpected movement of clutch actuating mechanism
Case installs clutch position sensor, and the current location of real-time monitoring clutch improves event to determine clutch real-time status
Hinder the accuracy of detection；When the unexpected combination of clutch actuating mechanism recurs number more than or equal to 3 times, then event is made a definite diagnosis
Barrier；When the unexpected separation of clutch actuating mechanism recurs number more than or equal to 3 times, then failure is made a definite diagnosis, failure is improved
The accuracy of detection.Therefore, the present invention improves the accuracy of fault detection.
3, machine is executed in clutch in the present invention a kind of detection and countermeasure of the unexpected movement of clutch actuating mechanism
After the unexpected combination failure of structure is made a definite diagnosis, current gear is kept, forces to combine clutch, make the return trip empty shelves automatically after parking；In clutch
After the unexpected separation failure of executing agency is made a definite diagnosis, current gear is kept, forces separation clutch, make the return trip empty shelves automatically after parking, on
Design is stated after failure is made a definite diagnosis, corresponding counter-measure is taken, improves the security performance of vehicle.Therefore, the present invention improves
The security performance of vehicle.
