Description
Technical field
The invention belongs to car transmissions transmission control fields, are related to clutch control skill when transmission up-shift
Art.
Background technique
AMT gearbox is one of numerous automatic transmission, and since congenital hardware condition is limited, gearshift procedure has longer
Power interruption time.For AMT automobile, it should guarantee the ride comfort of gearshift procedure, more to guarantee the quick of gearshift procedure
Property.Therefore, clutch for clutch control logic promotes shifting speed when increasing gear shift on the basis of not changing vehicle structure, and undoubtedly one
The method of a simple possible.Currently, clutch for clutch control logic is too simple during certain AMT car gear shiftings, when can also make gear shift
Between increase.
In AMT gearshift procedure, after TCU receives target gear signal, clutch separation can be controlled, then carry out hang shelves and
Gear selecting, in conjunction with clutch.General AMT vehicle gearshift procedure has several features：1, clutch eventually separation target position and
Just separation target position, small throttle large throttle do not have difference, and large and small throttle target is one；2, in gearshift procedure, in gear shift
Simultaneously, clutch position remains unchanged mechanism action, and clutch starts to act again after shift mechanism hangs shelves success；The above two o'clock meeting
Increase shift time and the power interruption time of AMT in various degree.
Summary of the invention
The technical problem to be solved in the present invention is to provide clutch control methods when a kind of AMT transmission up-shift, shorten AMT
Upshift time and power interruption time, effectively promotion driving experience.
In order to solve the above technical problems, technical scheme is as follows：
A kind of clutch for clutch control method during AMT transmission up-shift, method, which is totally said, to be believed by ECU acquisition throttle position
Number, it identifies that the clutch for clutch control logic in shifting up operation is rationally arranged in the driving intention of driver, TCU, is in gearshift procedure
Accelerator opening amount signal value, as TCU carry out clutch for clutch control correlative, its step are as follows：
(1) ECU acquires throttle position signal, identifies accelerator pedal position, and when arriving shift points, TCU issues upshift signal, hair
Motivation drops torsion simultaneously；
(2) TCU is according to working as different accelerator open degrees, selection control clutch to Place object point A, B, C, D, E, F point, until
Gear is static, and clutch kills, and gear shift is completed；
The setting of Place object point A, B, C, D, E, F point is：Clutch just separates target point and is known as A point, clutch separation
Enabling objective point is known as B point, and clutch is known as C point in separation target position eventually；Clutch combining target position is known as D point in gear shift, from
It closes just combining target point and is known as E point；Clutch cohesive process target position is known as F point；In the shifting up operation of different accelerator open degrees, if
Set different A, B, C, D, E, F point target positions.
The selection corresponding relationship of the accelerator open degree and clutch position target point is as follows：
1. A point target numerical value is small when small throttle accelerates upshift, indicating that separation degree is big, A point target numerical value is big when large throttle,
Indicate that just separation degree is small；Purpose is to reduce the power of driver to reduce acceleration change rate when large throttle gear shift
Interrupt sense.
2. C point target position is big when small throttle accelerates upshift, indicating that separation degree is small, C point target numerical value is small when large throttle,
Indicate that just separation degree is big, in order to shorten the clutch disengaging time of medium and small throttle, accelerate shifting speed.Small throttle accelerates
B point target numerical value is small when upshift, indicates that separation degree is big, and B point target numerical value is big when large throttle, indicates that separation degree is small.
3. C/D point target numerical value is consistent when small throttle accelerates to upshift, indicate that clutch position is constant when shift mechanism movement, greatly
What D point value was different degrees of when throttle is greater than C point value, and when indicating large throttle upshift shift mechanism movement, clutch is in different journeys
Degree combines, and shortens the clutch action time, reduces shift time.
4. E/F point target position is small when small throttle accelerates upshift, indicate that combination degree is small, E/F point target number when large throttle
Value is big, indicates that just combination degree is big, in order to which the clutch binding time of large throttle in shortening accelerates shifting speed.
This method compared with the prior art, increases the clutch for clutch control logic in shifting up operation, using in different accelerator open degrees
The different clutch of lower selection separates combining target, and shift time and power interruption are shortened in control from clutch separation, cohesive process
Time effectively improves driving experience.
Detailed description of the invention
Fig. 1 is clutch state schematic diagram in AMT shifting up operation；
Fig. 2 is AMT upshift clutch for clutch control flow chart.
Specific embodiment
For a better understanding of the present invention, this programme is carried out specifically below by way of specific embodiment combination attached drawing
It is bright.
Element of the present invention includes ECU, TCU, gearbox clutch position sensor, gearbox gear-shift motor position biography
Sensor.Accelerator opening amount signal value in gearshift procedure carries out the correlative of clutch for clutch control as TCU.
In upshift, clutch position signal 100 indicates that clutch is completely combined, and 0 expression clutch is kept completely separate.
Referring to Fig. 1, clutch position target point has A, B, C, D, E, F point, is respectively：Clutch just separates target point and is known as A
Point, clutch separation process target point are known as B point, and clutch is known as C point in separation target position eventually；Clutch combining target position in gear shift
Referred to as D point, just combining target point is known as E point for clutch；Clutch cohesive process target position is known as F point.
In the shifting up operation of different accelerator open degrees, different A, B, C, D, E, F point target positions is set.
Referring to fig. 2, shifting up operation clutch for clutch control method of the invention, includes the following steps：
1, the fixed accelerator open degree of driver accelerates, and ECU acquires throttle position signal, identifies accelerator pedal position, arrives gear shift
When point, TCU issues upshift signal, and torsion drops in engine simultaneously, and TCU controls clutch quick separating to A point, A point target value at this time
It 1 is obtained by tabling look-up.
2, clutch is slowly separated to B point, and B point target value show that the rate of departure is set according to actual match situation by looking into 1 table
It is fixed.
3, to C point, C point target value is obtained clutch quick separating by looking into 1 table, and shift mechanism is performed simultaneously choosing, hangs shelves mistake
Journey.
4, during shift mechanism executes choosing, hangs shelves, clutch is bound to D point in advance, and D point target value is obtained by looking into 1 table.
5, clutch is quickly bound to E point, and E point target value is obtained by looking into 1 table, in engine torque recovery.
6, clutch is quickly bound to F point, and F point target value is obtained by looking into 1 table, in engine torque recovery.
7, gear is static, and clutch kills, and gear shift is completed.
