In addition, the method also comprises: detect lines vehicle speed; Under the speed of a motor vehicle meets gearshift condition, then control gearshift by the mode by 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 exports 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 for detecting the telescopic location of clutch oil cylinder, with reflect 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 for monitoring the pressure of gearbox and delivering to traveling controller 5, to determine whether to carry out shift transformation action; Clutch Proportional valve 6 receives the output signal of traveling controller 5, and amplification drives clutch oil cylinder to move according to the curve of setting in traveling controller 5; Gear box electro-hydraulic control valve group 7 receives the output signal of traveling controller 5, and controls transmission internal oil circuit according to set model break-make to complete the conversion of gear.Vehicle speed sensor 8 for detecting actual running speed, and delivers to traveling controller 5.
Working principle: as shown in Figure 1, Figure 2 and Figure 4, first should be judged whether to shift gears according to the operating mode of equipment by traveling controller 5, the enable condition of gearshift for: the oil cylinder position detected by clutch oil cylinder position sensor 2 is in scope that gearshift allows, gearbox shifting pressure transducer 4 detects pressure in allowed band, the device unusual condition of clutch Proportional valve 6 not just beyond shown in action and Fig. 2 time (such as engine speed is too low or just do not shift gears when seriously falling speed, otherwise causes engine misses).
If above-mentioned gearshift condition meets, then controller exports shift handle to, removes its electronic lock.
When start to walk or shift transformation time, shift handle 1 by output four code signals to traveling controller 5, and then by walk controller 5 first exports clutch disengagement signal to clutch Proportional valve 6, clutch is thrown off rapidly.And the position of clutch oil cylinder is detected by clutch oil cylinder position sensor 2, and then judge whether clutch throws off by traveling controller 5, provide gear box electro-hydraulic control valve group 7 gearshift and start enable information.
Traveling controller 5 carries out 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 store target gear information, above-mentioned two kinds of gear information are compared, obtains pattern information.
The pattern recognition of gear adopts list type shift mode, specifically refers to that traveling controller 5 will
kind of all shift combinations possible are arbitrarily reduced to N+1 kind, N representation speed gear quantity in formula and do not comprise neutral.
Concrete simplification process works as
exist in kind of shift combination by N-n-N+m gear trip stop conversion time (in formula n, m are absolute value be more than or equal to 1 and the arithmetic number being less than N), 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 is wherein all be present in above-mentioned N+1 kind, and then reduces operation time and the storage space of controller 5.
Retreat the speed threshold of 3 gears for 3 gears that advance, as shown in Figure 5, the gear ratio of supposition F1 and R1, F2 and R2, F3 and R3 is the same simultaneously, then pattern information only comprises 6 kinds, respectively: R3-R2, R2-R1, R1-N, N-F1, F1-F2, F2-F3.
Then, traveling controller 5 recognizes after above-mentioned gearbox shifting starts enable information, 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 that gearbox shifting pressure transducer 4 detects in real time simultaneously calculates for traveling controller 5 and provides the complete information of gearbox shifting.
After above-mentioned gearbox shifting, traveling controller 5 is stored in the clutch oil cylinder predetermined action modeling curve in traveling controller 5 according to a certain mode invocation of above-mentioned pattern information, export clutch Proportional valve 6 to simultaneously, and then control clutch oil cylinder and call the predetermined curve of traveling controller 5 according to traveling controller 5 recognition modes and carry out action, and by the real-time detection clutch oil cylinder physical location of clutch oil cylinder position sensor 2 to revise due to machinery, electrically, the deviation brought of the link such as hydraulic pressure.
The detection clutch oil cylinder physical location that clutch oil cylinder position sensor 2 is real-time is also determined whether to shift gears complete by traveling controller 5.
With above-mentioned N-n-N+m gear control procedure corresponding to converting 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 when being less than or equal to setting difference v0 by the difference DELTA v between traveling controller 5 comparison object speed of a motor vehicle v1, automatically jump to the gearshift control procedure of N-n+1-N-n+2.
Above process reciprocation cycle, until reach target gear.
By the particularity of engineering machinery, should be able to subtract gear when touching on the brake or put neutral, the process that this step is done when above-mentioned identification shift mode is that traveling controller 5 preferentially exports clutch Proportional valve 6 to, leaps to neutral to make gearbox.
List type speed Control, greatly reduces the difficulty of many multimodal identification and process control, it also avoid trip stops simultaneously operate the impact that 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 being 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 repeat.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
