Control module 9 on reason system EMS is communicated；
One OCV Oil Control Valve 10 is located on speed changer, the control on the OCV Oil Control Valve and the engine management system EMS
Molding block 9 is communicated, and by separate driving chamber oil circuit 11 separated with power dispensing pump 16 driving chamber 13 connect, by combine drive
The combination driving chamber 14 of dynamic chamber oil circuit 12 and power dispensing pump 16 is connected, and the piston rod 15 of power dispensing pump 16 separates thick stick with described
Other end correspondence/the contact of bar 17.
The OCV Oil Control Valve 10 is 3-position 4-way type magnetic valve.
Principles and structure of the invention is as follows：
Clutch pedal 1, clutch assembly 2, vehicle speed sensor 5, engine speed sensor 7, engine assembly 8 and original
Manual automobile is consistent, it is not necessary to which work changes.Reception release bearing displacement letter is increased on former engine management system EMS
Number, gear signal and the control module of command signal is sent to OCV Oil Control Valve 10, release bearing position is set on release bearing 3
Displacement sensor 4, separates driving chamber 13, has increased the mounting hole of OCV Oil Control Valve 10 newly on speed changer, separates driving chamber oil circuit 11, knot
Driving chamber oil circuit 12, lubricating oil pump and oil input channel etc. are closed, all collection information of the system are all transmitted to engine management system EMS
On control module 9, control instruction is sent by the internal arithmetic program of control module 9, by OCV Oil Control Valve 10 control point
From driving chamber oil circuit 11 and being turned on and off with reference to driving chamber oil circuit 12, realize separating driving chamber 13 and combine driving chamber 14
Oil-filled or draining, so as to realize the separation of clutch and combine.
Clutch assembly 2 belongs to gerotor type structure, consistent with clutch control, due to having increased intelligent auxiliary system newly
System, in the control module of engine management system ESM, only in operating modes such as gearshift, startings, when trampling clutch pedal 1
Or when separating driving chamber 13 full of hydraulic oil, clutch assembly 2 is just in separation or semi-detached state.
The detailed control logic of the intelligent assistance system of this manual automobile clutch is (referring to Fig. 2)：
(1) when the tach signal that vehicle speed sensor 5 and engine speed sensor 7 are obtained is zero, vehicle speed sensor
Low pressure value signal is sent with engine speed sensor, the low pressure value signal is sent to control module 9 and led to by transmission line
Computing and judgement are crossed, then send to separating that driving chamber 13 is oil-filled, signal with reference to the draining of driving chamber 14 to OCV Oil Control Valve 10,
Now intelligent assistance system does not work.It is consistent with former manual automobile under the conditions of being somebody's turn to do；
(2) signal=0 when vehicle speed sensor 5, signal=1 of gear position sensor 6 or=R, engine speed sensor 7
Signal be≤VIdlingWhen (during idling), vehicle speed sensor, gear position sensor and engine speed sensor send high-voltage value letter
Number, the high pressure value signal is sent to control module 9 and by computing and judgement, then to OCV Oil Control Valve 10 by transmission line
Send separation driving chamber 13 draining, with reference to the oil-filled signal of driving chamber 14, clutch is fast in the presence of the intelligent assistance system
Speed is separated, and the signal that release bearing displacement transducer 4 feeds back to control module 9 this moment is S=Max states, and clutch all divides
From power transmission cut-out；
(3) signal ＞ 0 when vehicle speed sensor 5, signal=1 of gear position sensor 6 or=R, engine speed sensor 7
Signal be >=VIdlingWhen (during idling), the feedback signal=S of release bearing displacement transducer 4n(it is shown in Table 1, SnAccording to demarcation during value
Obtain, the value is embodied directly in the separation degree of clutch, meets complex working condition requirement), vehicle speed sensor, gear position sensor and
Engine speed sensor sends high pressure value signal, and the high pressure value signal is sent to E control modules 9 and passed through by transmission line
Computing and judgement, then send a point PID (Proportion Integration to OCV Oil Control Valve 10
Differentiation) duty cycle signals, the separation driving chamber 13 in this stage is in draining and oil-filled alternating conversion and combines
The alternating that driving chamber 14 is in oil-filled and draining is changed, and the intelligent assistance system is met driving under automatic transmission state
Operating mode, the operating mode of driving adapts to the works such as traffic congestion jogging, vehicle start, abrupt slope starting, reversing storage, low-speed big climb very steep slopes
Condition, driver need not control clutch pedal；In engineering in practice, the adjuster control law being most widely used is ratio
Example, integration, differential control, abbreviation PID control, also known as PID regulations.PID controller (proportional-integral derivative controller)
(4) as signal ≠ 1 of gear position sensor 6 or ≠ R, the signal S=0 of release bearing displacement transducer 4, in normal row
, it is necessary to driver's control clutch pedal, realizes that gear is changed when sailing the plus-minus gear in operating mode；
Control module 9 in engine management system EMS is the control centre of the intelligent assistance system, data SnBy whole
Logo is obtained surely, SnDemarcate more detailed, the driving of vehicle is more comfortable.In actuator implementation procedure, driving chamber 13 and knot are separated
Driving chamber 14 is closed respectively according to the rapid change of oil-feed or the oil return for separating driving chamber oil circuit 11 and combination driving chamber oil circuit 12
To control Sn, while SnEnter control module 9 as feedback signal, to meet the S of next stagenPrepare, therefore machine oil is controlled
Valve 10 is dither during intelligent assistance system works, and SnIt is amendment in real time.
