Realize a kind of pure electric vehicle of said method, at least comprise drive motor, entire car controller and the direct electric machine controller controlling described drive motor, also comprise speed control switch, described speed control switch is driving switch, described speed control switch connects the input of described entire car controller, the output of described entire car controller connects the input of described electric machine controller, and the output of electric machine controller connects the control end of described drive motor.With reference to Fig. 3, the speed control switch 11 of pure electric vehicle is arranged on the power takeoff control panel of pure electric vehicle, entire car controller 12 is connected to by connection lead, the output of described entire car controller 12 connects the input of described electric machine controller 13, and the output of electric machine controller 13 connects the control end of described drive motor 14.Entire car controller 12 chooses the rotating speed of target of described drive motor 14 according to the gear signal that speed control switch 11 exports, and described rotating speed of target is sent to electric machine controller 13, described electric machine controller 13 controls described drive motor 14 and runs according to described rotating speed of target.
Drive motor in the present invention possesses two kinds of mode of operations: rotating speed control mode and torque control mode.
Being distinguished as of two kinds of patterns: under " rotating speed control mode ", electric machine controller only responds the rotary speed instruction (i.e. rotating speed of target) that entire car controller sends; Corresponding, under " torque control mode ", electric machine controller only responds the torque command (i.e. target torque) that entire car controller sends.
Example:
Rotating speed control mode: VCU(entire car controller) only need send to MCU(electric machine controller) requiring now that drive motor rotates with 500rpm, 500rpm is exactly rotating speed of target.After MCU receives instruction, control drive motor output torque, but the size of output torque is relevant with load, if motor load is little, the actual output torque of drive motor then reaching identical actual speed is little, as long as just can maintain 500rpm, if motor load is large as 10Nm, then need larger actual output torque just can reach same actual speed, perhaps output torque as actual in drive motor will bring up to 100Nm could maintain 500rpm.That is the rotating speed of target actual needs realizing VCU exports how many moments of torsion, and be that MCU oneself controls completely, the rotating speed that therefore VCU calculates is rotating speed of target, and the rotating speed that drive motor now really reaches is its actual speed;
Under rotating speed control mode, what stress is whether drive motor actual speed can be consistent with VCU the set goal rotating speed.Due to control accuracy reason, be do not have energy on all four, be 500rpm as VCU sends rotating speed of target, actual speed fluctuates (495rpm to 505rpm) among a small circle near 500rpm, just thinks and meets operating needs.
Torque control mode: VCU only need send to MCU to need now drive motor to export how many moments of torsion.Such as, during vehicle travels, Das Gaspedal has been operated half, and VCU parses the moment of torsion that chaufeur needs 100Nm accordingly.This 100Nm is exactly target torque, it can be sent in MCU, after MCU receives this instruction, control drive motor and export 100Nm, and for same 100Nm, same gear (such as 3 gears), if the level road speed of a motor vehicle can arrive 80km/h, motor speed is just at 4000rpm, if upward slope, 100Nm can only allow vehicle with 40km/h speeds, and corresponding motor speed also just becomes 2000rpm.The moment of torsion that VCU calculates is target torque, and the moment of torsion that drive motor now really has is its actual torque.
Same needs are clear and definite: under torque control mode, the target torque that drive motor actual torque and VCU send can't reach completely the same, the target torque of the 100Nm also sent for VCU, the actual output torque of drive motor can not be equal to 100Nm, always have little positive and negative deviation (such as actual output torque is between 95Nm to 105Nm), if do not affect the control of actual vehicle in engineering, this error allows.
Under rotating speed pattern: only control rotating speed, a certain rotating speed may correspond to different moments of torsion;
Under torque mode: a control torque, a certain moment of torsion may correspond to different rotating speeds.
For the specific works flow process of a pure electronic kitchen waste cart, the present invention is further described below.
In a kitchen waste-skip based on the exploitation of above-mentioned pure electric vehicle, apply 3 grades of speed control that control method of the present invention carries out power takeoff.Wherein the corresponding speed setting of low gear is 100rpm, and mid ranger is 200rpm, and high speed gear is 800rpm.
Driver vehicle arrives operating location and prepares to collect changing food waste, and after vehicle comes to a complete stop, change speed gear box hangs neutral, pull-up parking brake, and closed power take-off valve, vehicle enters dress mode of operation.After power takeoff completes and puts into gear, entire car controller just can drive motor.Chaufeur now moves on to operation vehicle operates the standby control stalk of upper installing, control button, speed control switch etc. outward from operator's compartment.First chaufeur forwards speed control switch to mid ranger from closedown shelves, and trunk upper cover is opened in operation, promotes sewage disposer.When sewage disposer is promoted close to roof, for avoiding the too fast turnover of sewage disposer to tip rubbish caused splashing, forward speed control switch to low gear, command driven motor runs with slow speed of revolution.Rubbish is toppled over complete, puts down in sewage disposer process, again can heighten motor speed (mid ranger), make sewage disposer returning quickly.After sewage disposer is taken, close trunk upper cover, complete a garbage reclamation flow process.Speed control switch is screwed to closedown shelves by chaufeur, and disconnect power take-off valve, power takeoff is switched to driving mode after completing and plucking gear.
After garbage reclamation completes, vehicle is sailed back changing food waste and is reclaimed factory, and treat that vehicle comes to a complete stop, chaufeur hangs the gear that makes the return trip empty, pull-up parking brake, closed power take-off valve, vehicle enters dress mode of operation.By speed control switch furnishing mid ranger, control to open rear cabinet tail-gate, release rubbish, can high speed gear be used, to accelerate operating speed in control push pedal return process.
For the kitchen waste cart generated based on the present invention, it distinguishes the standby mode of operation under different run location or running state of different upper installings, make it with different speed operation, thus prevent that rubbish from splashing, the too fast release of rubbish causes the secondary pollution of spilling and Lou causing, the seating velocity of trunk inner pushing plate can be accelerated again, improve vehicle operation efficiency.
In the detailed description of the invention of above-mentioned kitchen waste cart, power takeoff can carry out third gear speed governing, install different upper installing for time, many grades of rotating speeds can be adopted, but arranging rotating speed should meet the following requirements:
Low gear, can set up the basic pressure of hydraulic efficiency pressure system, and power takeoff should be able to ensure that all types of upper dress device action can normally run, but likely running velocity is excessively slow, affects special vehicle work efficiency;
Mid ranger, between low gear and high speed gear, the special vehicle will be able to assembled according to pure electric vehicle chassis is mated;
High speed gear, limits by following condition: the hydraulic system pressure that a) power takeoff provides should be less than upper installing and be less than the highest design kinematic velocity for the safe oil pressure of hydraulic control system, b) upper dress equipment moving speed, c) can not cause other personnel, vehicle safety hidden danger.
The present invention by increasing speed control switch in pure electric vehicle, power takeoff rotating speed is changed for the standby drive motor rotating speed that can adjust at any time of the upper installing that function is more complicated, and then the pressure of adjustment upper dress hydraulic control system, the running velocity that in change, installing is standby, to adapt to the operating feature that on certain, installing is standby, therefore same pure electric vehicle and different upper installings can be made for mating, form the special vehicle vehicle of different purposes, can be widely used in being obtained by power takeoff filling equipment dynamic, and controlled in the pure electric vehicle of power takeoff rotating speed by drive motor rotating speed, thus both met the requirement of vehicle platform compounds, sinuous special vehicle job requirements can be met very well again.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
