In above-mentioned control method, it usually needs the long period could cause the clutch to be in stable micro- cunning and rub state, cause car In the presence of certain vibratory impulse in starting and gearshift, the comfortableness taken is influenceed.
In view of the above-mentioned problems, the embodiment provides a kind of control method of clutch, it is right that methods described passes through The decrease speed of the clutch output torque value is controlled, and the rotating speed between the clutch driving disk and driven disc When difference is equal to the first speed discrepancy, i.e., the moment of torsion of clutch output is controlled, rather than only pass through presently described clutch The moment of torsion that speed discrepancy between rotating plate and driven disc exports to the clutch is controlled, therefore, in the embodiment of the present invention The control method of the clutch can rapidly control clutch to be in stable micro- cunning and rub state.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention Specific embodiment explain.
As shown in figure 1, the embodiments of the invention provide a kind of control method of clutch, methods described can include as follows Step：
Step 11, the torque value of engine output is obtained.
Step 12, the torque value of the clutch output is controlled to be down to the moment of torsion of the engine output with First Speed Value.

Step 15, judge whether the speed discrepancy between the clutch driving disk and driven disc is equal to the first speed discrepancy.
When the speed discrepancy between the clutch driving disk and driven disc is equal to the first speed discrepancy, step 16 is performed, it is no Then perform step 14.
Step 16, according to the speed discrepancy between the clutch driving disk and driven disc, the torsion to clutch output Square is controlled.
Step 17, it is poor to judge whether the speed discrepancy between the clutch driving disk and driven disc is equal to rotating speed of target.
When the speed discrepancy between the clutch driving disk and driven disc is equal to rotating speed of target difference, terminate above-mentioned controlling stream Journey, otherwise continue executing with step 16.
Step 11 to 17 is described in detail with reference to Fig. 2：
Fig. 2 is when being controlled using the control method of clutch described in the embodiment of the present invention, corresponding curve is illustrated Figure.As shown in Fig. 2 figure (a) is the curve synoptic diagram that moment of torsion changes over time, figure (b) is that the curve that rotating speed changes over time shows It is intended to, the curve synoptic diagram that figure (c) speed discrepancy changes over time.In (a) is schemed, curve 1 represents that the output of the clutch is turned round Square value changes curve, curve 2 represent the output torque value changes curve of the engine.In (b) is schemed, curve 3 represents described The rotation speed change curve of clutch driving disk, curve 4 represent the rotation speed change curve of the clutch driven disk.In (c) is schemed, Curve 5 represents rotating speed of target difference curve, and curve 6 is actual speed difference change curve.In the t1 periods, the clutch is in lock Only state.In the t2 periods, the clutch is declined with the first decrease speed.In the t3 periods, the clutch is with second Reduction of speed degree declines.It is defeated to the clutch according to the speed discrepancy between the clutch driving disk and driven disc in the t4 periods The moment of torsion gone out is controlled.
In specific implementation, the rotating plate of clutch is connected with engine, the input axis connection of driven disc and speed changer.It is logical In the case of often, corresponding velocity sensor is provided with the rotating plate and driven disc of the clutch, can be according to the clutch Velocity sensor on the rotating plate of device, the actual speed of the engine is got, then the actual speed is carried out related Calculate, to obtain the torque value (i.e. curve 2) of the engine output.
As seen from Figure 2, the clutch that is, in the t1 times, is generally in locking shape before state of rubbing sliding in a subtle way is entered State.When the clutch is in lockup state, according to curve 3 and curve 4 as can be seen that turning between rotating plate and driven disc Speed difference is steady state value.Now according to curve 1 and curve 2 as can be seen that the torque value that the clutch exports is more than described start The torque value of machine output.When the clutch by lockup state enter it is in a subtle way sliding rub state when, i.e., in the t2-t4 periods, it is described from The torque value of clutch output is begun to decline, and speed discrepancy also can respective change between rotating plate and driven disc.Control the clutch The torque value exported with engine, to ensure the starting of the vehicle and gearshift performance.
Specifically, when the decrease speed to the clutch output torque value is controlled, can first control it is described from The torque value of clutch output is down to the torque value of the engine output (referring to curve 1 within the t2 periods with First Speed Change procedure), that is, the torque value for causing engine described in the torque value fast approaching of the clutch output to export, now, institute State the speed discrepancy between the master and slave moving plate of clutch and still keep constant (referring to 3 and 4 change within the t2 periods of curve Journey).When the torque value of clutch output is equal to the torque value of engine output (A points), then described in controlling from The torque value of clutch output continues to decline (referring to change procedure of the curve 1 within the t3 periods) with second speed, now described The rotating speed of the master and slave moving plate of clutch gradually increases (referring to 3 and 4 change procedure within the t3 periods of curve), corresponding rotating speed Difference also gradually increases (referring to change procedure of the curve 6 within the t3 periods).
In specific implementation, the First Speed is more than second speed, and the value of the First Speed and second speed can To be set according to actual conditions.When the torque value for stating clutch output is equal to the torque value of engine output, control The torque value for making the clutch output is declined with second speed, and the master and slave moving plate of the clutch can be caused slowly to open, Prevent the speed discrepancy between master and slave moving plate from increasing suddenly.
With the gradual increase of actual speed difference between the master and slave moving plate of the clutch, when actual speed difference increases During to the first speed discrepancy (i.e. B points), the clutch is exported according to actual speed difference between the master and slave moving plate of the clutch Moment of torsion is controlled.
Because first speed discrepancy is poor less than rotating speed of target, therefore, controlled in the output torque to the clutch When processed, it can first reduce the pressure to the clutch so that actual speed difference is quick between the master and slave moving plate of clutch increases Greatly；Afterwards, the clutch is obtained after pressure is reduced, and actual speed is poor between master and slave moving plate.If the clutch is reducing After pressure, actual speed difference is poor equal to rotating speed of target between master and slave moving plate, then reaches the control purpose to the clutch, instead Then continue according to the clutch after pressure is reduced, actual speed is poor between master and slave moving plate, the output to the clutch Moment of torsion is controlled, until the speed discrepancy between the clutch driving disk and driven disc is poor equal to rotating speed of target.
As seen from Figure 2, using the control method of clutch described in the embodiment of the present invention, the clutch is exported Torque value be controlled after, the increasing degree of the master and slave moving plate rotating speed of clutch is moved closer to (referring to curve 3 and 4 in t4 Change procedure in period), it is poor (referring to curve 6 in the t4 periods that corresponding actual speed difference also moves closer to rotating speed of target Interior change procedure), the difference between the moment of torsion of the moment of torsion and engine of output output is also gradually stablized (to exist referring to curve 1 and 2 Change procedure in the t4 periods).At the end of the t4 times, the clutch enters stable micro- cunning and rubbed state.
In specific implementation, it is poor that first speed discrepancy is less than rotating speed of target.Wherein, the rotating speed of target difference can be one Concrete numerical value, or a rotating speed of target difference section.When rotating speed of target difference is a rotating speed of target difference section, described One speed discrepancy is less than the minimum value in the rotating speed of target difference section.For example, when first speed discrepancy is 15rpm, the target Speed discrepancy can be 30rpm, or [25rpm, 30rpm].
