The step content in the control process of target pattern dispatching management module is made a concrete analysis of below:
Step 21, locking speed MAP is preset in TCU, locking releases speed MAP, skidding regulation speed MAP and solution of skidding
Except speed MAP.According to the actual-gear and above-mentioned MAP of gas pedal opening amount signal and automatic transmission, can be obtained current
Locking target vehicle speed and unlock target vehicle speed under operating condition etc..
Step 22~step 23, if current vehicle speed is greater than locking target vehicle speed or current goal mode has been lockdown mode
And speed is greater than locking and releases target vehicle speed, then torque-converters target pattern is set as lockdown mode.Special setting locking releases vehicle
Fast MAP, what may be occurred when being to avoid current vehicle speed from fluctuating near target vehicle speed frequently switches on movement.
Step 24~step 26, ibid, the skidding control target vehicle speed under available current working and the releasing mesh that skids
Speed is marked, if current vehicle speed is less than locking speed and is greater than control target vehicle speed of skidding, torque-converters target pattern is set as solving
Latching mode；Otherwise, torque-converters target pattern is set as latching mode.
Step 21~step 26 divides basic unlock-skidding-locking region according to above-mentioned various MAP.In addition, also
It need to comprehensively consider according to step 27 based on the requirement such as the various restrictive conditions of torque-converters characteristic and shifting comfort, be various mesh
It marks mode setting and enables condition and trigger condition.Such as locking and the minimum speed limitation of slip mode, shifting comfort cannot
How target pattern switches under the conversion of target pattern, high/low temperature mode in the case where guarantee, to carry out comprehensive assessment and most
Target pattern is determined eventually.
Step 28, when TCC target pattern is to skid, according to speed, engine torque and each shelves being preset in TCU
Target value of slip MAP under position obtains target value of slip nSlipTar.
Based on above step, locking region can greatly optimize fuel economy with further expansion；And in locking
The poor region of zone comfort improves comfort by skidding control；The originally shift under locking operating condition, can also be by beating
Slip control system promotes shift quality.After target is determined, control process module is divided into unlock by the present invention, oil-filled, is engaged, sliding
Following difference, 6 kinds of states of locking and release.
Two, below in conjunction with Fig. 3, TCC control process module is described in detail:
TCC target pattern is divided into locking, skidding and unlock by the present invention.
The TCC process control, comprising: unlocked state control；Oil-filled state control；Engagement state control；Slippage with
It is controlled with state；Lockup state control；Release conditions control.
Unlocked state target oil pressure is arranged to the negative oil pressure of periodic square wave form, to prevent the viscous event of solenoid valve
Barrier.
The control method needs bonding state target oil pressure Peng calculation method to be controlled.
PI control, the target oil pressure calculation method of slippage following state are introduced in slippage following state.
The calculating of minimum oil pressure needed for TCC transmitting torque replaces actual torque and lockup state target oil with torque is estimated
The calculation method of pressure.
As shown in figure 3, the control process of the TCC process control module is:
Start；
Step 301, unlocked state control；
Step 302 judges whether target pattern becomes skidding or locking, if it is, entering step 303；If it is not, then
Enter step 316；
Step 303, Oil feeding process control；
Step 304 judges whether target pattern returns to unlock, if it is, return step 301；If it is not, then entering step
Rapid 305；
Step 305 judges that target pattern keeps skidding or locking and whether Oil feeding process is completed, if it is, into
Step 306；If it is not, then return step 303；
Step 306, cohesive process control；
Step 307 judges whether target pattern returns to unlock, if it is, entering step 301；If it is not, then entering step
Rapid 308；
Step 308 judges that target pattern keeps skidding or locking and whether cohesive process is completed, if it is, into
Step 309；If it is not, then return step 306；
Step 309, the control of slippage following state；
Step 310 judges whether target pattern returns to unlock, if it is, entering step 315；If it is not, then entering step
Rapid 311；
Step 311 judges whether target pattern becomes locking and followed target value of slip, if it is, entering step
312；If it is not, then return step 309；
Step 312, lockup state control；
Step 313 judges whether target pattern returns to unlock, if it is, entering step 315；If it is not, then entering step
Rapid 314；
Step 314 judges whether target pattern becomes to skid, if it is, return step 309；If it is not, then returning to step
Rapid 312；
Step 315, release conditions control；
Step 316 judges whether draining is completed, if it is, return step 302；If it is not, then return step 315.
The step content in TCC control process is made a concrete analysis of below:
Unlocked state is set as default conditions by step 301~step 302, when target pattern always remains as latching mode
When, program is just always maintained in this state.Unlocked state target oil pressure is arranged to the negative oil pressure of periodic square wave form, period
For 100ms, first half cycle oil pressure is set as -3bar, and later half period oil pressure is set as -2bar；Both it can guarantee that release oil pressure is greater than lock
Only oil pressure is to realize control target, and it is viscous to prevent solenoid valve that valve core of the electromagnetic valve can be allowed to generate periodical micro-displacement
Failure.
When target pattern becomes skidding or locking by unlocking, unlocked state jumps to oil-filled state.
Step 303~step 305, according to TCC hydraulic control circuit characteristic, by oil-filled state be divided into again the sub- state of fast charge and
The sub- state of trickle charge.Clutch play is quickly eliminated with higher oil pressure in the sub- state of fast charge, when fast charge target oil pressure and fast charge
Between table look-up to obtain by gearbox oil temperature.After the completion of the timing of fast charge time, into the sub- state of trickle charge.The sub- state of trickle charge is then with lower
Oil pressure be slowly reached TCC semi-linkage point, trickle charge target oil pressure and trickle charge time be also tabled look-up to obtain by gearbox oil temperature (it is fast/
Trickle charge oil pressure MAP and it is faster slower to fill time MAP all related to oil temperature, and be preset in TCU).After the completion of the timing of trickle charge time, into
Enter engagement state.
Step 306~step 308 enables TCC to reach transmitting as early as possible by the control to engagement state target oil pressure Peng
The safe oil pressure of target torque needs simultaneously ensures that the comfort in engaging process is unaffected.Peng calculates as follows:
Ttcc=Te-Tp=Te-Kc × Ne2
S=Nt/Ne
Wherein, Ttcc is the torque of TCC transmitting；Te is engine torque；Tp is that pump impeller transmits torque；Ne engine turns
Speed；Nt secondary speed；Kc is torque-converters capacity coefficient, is the inherent characteristic of fluid torque-converter, tables look-up to obtain by torque-converters speed ratio s
(corresponding relationship of Kc and s are preset in TCU).
Ptcc=Ttcc/ (μ d × A × Rc × Z)
Wherein, Ptcc is the minimum oil pressure of theory needed for the above-mentioned torque T tcc of transmitting；μ d is dynamic friction coefficient, and A rubs for TCC
Pad area, Rc are the secondary mean radius of TCC friction, and Z is TCC the piece number.
In practical application example, in engine torque very little even negative value, these operating conditions need to carry out Ptcc
Amendment；Tabled look-up according to Te and nSlipTar (this MAP is obtained by practical calibration) obtain target oil pressure and replace Ptcc.
Peng=Pini+ (Ptcc-Pini) × t/Teng
Pini is original oil pressure when entering engagement state；Engaging time Teng is looked by engine speed and engine torque
Table obtains, and the corresponding relationship of engaging time MAP and engine speed, engine torque is preset in TCU；T is into the state
Start the time of timing.
Engaging time timing is arrived, and slippage following state is jumped to.
Step 309~step 311 introduces PI in slippage following state and controls to adjust target oil pressure to follow target to skid
Value, the target oil pressure Pslip calculating process of slippage following state are as follows:
Pslip=Ptcc+Pfb
Pfb=Kp × e+Ki × Σ e
E=Ne-Nt-nSlipTar
Ptcc calculating process is same as above；Pfb is feedback oil pressure, including proportional and integral item parts, through PI controller
It is calculated.Kp is proportionality coefficient, and Ki is integral coefficient；E is the error of practical slippage (i.e. Ne-Nt) and target value of slip；Product
Subitem is initialized when entering the mode, and needs to carry out saturation limit value to integral term.
Target pattern is LOCK, and when practical slippage < 10rpm, jumps to lockup state from slippage following state.
Step 312~step 314, lockup state needs thoroughly locked TCC, therefore target oil pressure is the bigger the better；But it is larger
Oil pressure will lead to fuel economy variation.Lockup state target oil pressure Plock calculates as follows:
Plock=Ptcc+Phold
Phold=Ptcc × Ks
The calculating of Ptcc is same as above, only replaces actual engine torque with estimating torque T fc in calculating process
Te；Phold corresponds to the torque capacity that TCC can additionally be born, relationship such as 1 institute of table of coefficient of torque reserve Ks and gas pedal aperture
Show:
Table 1
| Gas pedal aperture | 0 | 10 | 20 | 50 | 70 | 100 |
| Ks | 10 | 20 | 25 | 10 | 7 | 5 |
Torque T fc is estimated, is to prevent engine torque under transient condition from increasing too fast and fluid torque-converter hydraulic spy
Property lag cause oil pressure insufficient；Therefore, it can be timing according to the difference of gas pedal aperture, take current throttle aperture and start
The peak torque that engine can export under machine speed conditions；Otherwise, actual engine torque is continued to use.
If target pattern becomes slip mode, then state transition to slippage following state in lockup state.
If in slippage follow or lockup state in, target pattern becomes latching mode, then state transition to release conditions.
Step 315~step 316, release conditions table look-up to obtain the draining time according to Ne and input torque, by this time into
Row draining.
Prel=P0 × (1-t/Trel)
P0 is original oil pressure when entering release conditions；The draining time, Trel was tabled look-up by engine speed and engine torque
It obtains, the corresponding relationship of draining time MAP and engine speed, engine torque is preset in TCU；T is to open into the state
The time of beginning timing.
The timing of draining time is arrived, i.e., draining process is completed, state transition to unlocked state.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
