Transmission system in, the separation of clutch and to combine be usually to be realized by pneumatic control.In pneumatic clutch control process
In, clutch be in it is sliding rub the stage when, the torque of clutch transmitting is influenced especially big by clutch displacement, works as clutch compressing disc
When mobile speed is larger, the change in torque of clutch transmitting is larger, therefore will cause shrugging one's shoulders and influencing vehicle start for vehicle
With the ride comfort of shift.
Since the compressibility of gas is larger, pneumatic control has the characteristics that larger time lag, gas build the pressure time compared with
Long and response is slower.In vehicle start, when clutch reach it is sliding rub position when, after the solenoid valve of pneumatic circuit is closed, when from
Clutch carry out again it is sliding rub position adjustment when, the clutch operating response time is long, and clutch starts clutch compressing disc when movement
It is displaced the torque sharp increase larger, clutch transmits, vehicle is easy to shrug one's shoulders.In order to guarantee that vehicle start is steady, in clutch slipping
Stage needs to control clutch compressing disc movement steadily, and clutch position adjusts quick response.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, provides a kind of double proportional plus integral control methods of pneumatic clutch, uses
In solve to guarantee clutch it is sliding rub the stage when clutch compressing disc movement it is steady and guarantee clutch position adjustment quick response
Problem, to ensure that vehicle start is steady.
The purpose of the present invention is what is be achieved through the following technical solutions:
A kind of double proportional plus integral control methods of pneumatic clutch, comprising the following steps:
In the clutch slipping stage, calculation of tabling look-up is passed through according to accelerator open degree, engine speed and transmission input shaft revolving speed
Method determines clutch separation target position and clutch combining target position；According to clutch separation target position and clutch knot
It closes target position and the intake valve of clutch and the exhaust valve of clutch is controlled simultaneously by proportional plus integral control method, from
The intake valve and exhaust valve of clutch work at the same time, to separate and combine controlling to clutch simultaneously.
In clutch separation control process, according to clutch separation target position, pass through proportional plus integral control method control
Clutch intake valve processed, proportionality coefficient P1According to the difference and clutch of clutch separation target position and clutch physical location reality
The difference of border position and clutch friction point is determining by inquiring arithmetic, integral coefficient I1According to clutch separation target position with from
The difference of clutch physical location is determined by inquiring arithmetic, according to identified proportionality coefficient P1With integral coefficient I1, to clutch into
Row separation control.
In clutch combination control process, according to clutch combining target position, pass through proportional plus integral control method control
Clutch exhaust valve processed, proportionality coefficient P2According to the difference and clutch of clutch combining target position and clutch physical location reality
The difference of border position and clutch friction point is determining by inquiring arithmetic, integral coefficient I2According to clutch combining target position with from
The difference of clutch physical location is determined by inquiring arithmetic, according to identified proportionality coefficient P2With integral coefficient I2, to clutch into
Row separation control.
In the control process of clutch, clutch separation target position and clutch combining target according to accelerator open degree,
Engine speed and transmission input shaft revolving speed and real-time change；Proportionality coefficient P1、P2With integral coefficient I1、I2It is calculated by tabling look-up
Method determines in real time, according to proportionality coefficient P1、P2With integral coefficient I1、I2By proportional plus integral control method simultaneously to clutch into
Row separation and combination control, the air inlet and exhaust valve of clutch work at the same time, and the platen of clutch is in dynamic balance state, clutch
Physical location is between clutch separation target position and clutch combining target position.
Compared with prior art, profitable fruit of the invention is:
1, it is worked at the same time in clutch slipping stage, clutch intake valve and clutch exhaust valve, clutch position adjustment
Response is fast and steady.
2, for clutch when carrying out clutch position adjustment in the sliding stage of rubbing, clutch compressing disc movement is steady, clutch transmitting
Change in torque is steady, ensure that vehicle start is steady.
