In addition, the method also comprises: detect running speed; Satisfy in gearshift condition situation in the speed of a motor vehicle, then by controlling gearshift by the mode of gear conversion.
Be specially:
As depicted in figs. 1 and 2, clutch control device comprises gear shift operation device 1, clutch oil cylinder position sensor 2, brake pedal sensor 3, gearbox shifting pressure transducer 4, traveling controller 5, clutch Proportional valve 6, gear box electro-hydraulic control valve group 7, vehicle speed sensor 8.
Gear shift operation device 1 output tetrad coding shift signal receives the gearshift enable signal that traveling controller 5 provides simultaneously, when gear shift operation device 1 receives above-mentioned gearshift enable signal, just can carry out gear shift operation; Clutch oil cylinder position sensor 2 telescopic locations for detection of the clutch oil cylinder, with reflection clutch and motor in conjunction with situation; Brake pedal sensor 3 provides brake signal, and delivers to traveling controller 5; Gearbox shifting pressure transducer 4 is used for monitoring the pressure of gearbox and delivering to traveling controller 5, carries out the shift transformation action to determine whether; Clutch Proportional valve 6 receives the output signal of traveling controllers 5, and amplifies and drive the clutch oil cylinder and move according to the curve of traveling controller 5 interior settings; Gear box electro-hydraulic control valve group 7 receives the output signal of traveling controllers 5, and control the gearbox internal oil passages according to the set model break-make to complete the conversion of gear.Vehicle speed sensor 8 is for detection of the running speed of reality, and delivers to traveling controller 5.
Working principle: as Fig. 1, Fig. 2 and shown in Figure 4, at first should judge whether and to shift gears by the operating mode of traveling controller 5 according to equipment, the condition of enabling of gearshift is: the oil cylinder position that is detected by clutch oil cylinder position sensor 2 be in scope that gearshift allows, pressure that gearbox shifting pressure transducer 4 detects in allowed band, clutch Proportional valve 6 is not moving and shown in Figure 2 beyond the device unusual condition time (too low or just do not shift gears when seriously falling speed such as engine speed, otherwise cause engine misses).
If above-mentioned gearshift condition satisfies, controller exports shift handle to, removes its electronic lock.
When starting or shift transformation, shift handle 1 will be exported four code signals to traveling controller 5, and then at first export clutch disengagement signal to clutch Proportional valve 6 by walking controller 5, and clutch is thrown off rapidly.And detected the position of clutch oil cylinders by clutch oil cylinder position sensor 2, and then judge by traveling controller 5 whether clutches throw off, provide gear box electro-hydraulic control valve group 7 gearshift beginning enable information.
Traveling controller 5 carries out the gear pattern recognition simultaneously, comprise current shift (gear before shift control), target gear (gear after shift control) and shift transformation, concrete recognition process is: identify and store current shift information, identification and storage target gear information, above-mentioned two kinds of gear information are compared, obtain pattern information.
List type gearshift pattern is adopted in the pattern recognition of gear, refers to that specifically traveling controller 5 will
Kind all arbitrarily possible shift combinations be reduced to the N+1 kind, N representation speed gear quantity and do not comprise neutral in formula.
Concrete simplification process is to work as
There is when trip stopping conversion by the N-n-N+m gear (in formula, n, m are absolute value more than or equal to 1 and less than the arithmetic number of N) in kind of shift combination, be translated into N-n-N-n+1, N-n+1-N-n+ 2 ...-..., N+m-2-N+m-1, N+m-1-N+m, any one pattern so wherein is all to be present in above-mentioned N+1 kind, and then reduces operation time and the storage space of controller 5.
Retreat 3 speed thresholds that keep off as example take 3 gears that advance, as shown in Figure 5, suppose that simultaneously F1 is the same with the gear ratio of R1, F2 and R2, F3 and R3, pattern information only comprises 6 kinds, is respectively: R3-R2, R2-R1, R1-N, N-F1, F1-F2, F2-F3.
Then, traveling controller 5 recognizes above-mentioned gearbox shifting begin enable information after, export the gear shifting signal corresponding with above-mentioned target gear to gear box electro-hydraulic control valve group 7, and keeping this signal characteristic until obtain new shifting commands or shutdown, gearbox carries out the combined transformation action of gear according to the logic of gear box electro-hydraulic control valve group 7; The force value of gearbox shifting pressure transducer 4 detection in real time simultaneously calculates for traveling controller 5 the complete information of gearbox shifting that provides.
After above-mentioned gearbox shifting is complete, traveling controller 5 is stored in the interior clutch oil cylinder predetermined action modeling curve of traveling controller 5 according to a certain mode invocation of above-mentioned pattern information, export simultaneously clutch Proportional valve 6 to, and then control the clutch oil cylinder and call traveling controller 5 predetermined curves according to 5 recognition modes of traveling controller and move, and by the real-time detection clutch oil cylinder physical location of clutch oil cylinder position sensor 2 to revise the deviation of bringing due to links such as mechanical, electric, hydraulic pressure.
The detection clutch oil cylinder physical location that clutch oil cylinder position sensor 2 is real-time and by traveling controller 5 determine whether shift gears complete.
With the above-mentioned N-n-N+m gear corresponding control procedure of conversion of trip stopping be: after first having carried out N-n-N-n+ 1 according to above-mentioned control flow, wait for that vehicle speed sensor 8 detects actual running speed v2, and by the difference DELTA v between traveling controller 5 comparison object speed of a motor vehicle v1 when setting difference v0, automatically jump to the gearshift control procedure of N-n+1-N-n+ 2.
Above process reciprocation cycle is until reach the target gear.
By the particularity of engineering machinery, should be able to subtract gear or put neutral when touching on the brake, the processing that this step does when above-mentioned identification gearshift pattern is that traveling controller 5 preferentially exports clutch Proportional valve 6 to, so that gearbox is leapt to neutral.
The list type speed Control has greatly reduced the difficulty of many multimodal identifications and process control, the impact that the operation of also having avoided simultaneously trip stopping brings and to machine and ground and damage.
The present invention also provides a kind of engineering machinery, it is characterized in that, described engineering machinery is provided with above-mentioned clutch control device.Wherein, this project machinery is road roller.
Because above-mentioned clutch control device has above-mentioned technique effect, therefore, the engineering machinery that is provided with this clutch control device also should possess corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby give unnecessary details.
The above is only preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
