Description
Technical field
The present invention relates to electric automobile field, more particularly, to a kind of power takeoff control for the pure electronic special-purpose vehicle of manual gear
System and method.
Background technology
In order to accelerate new-energy automobile industry development, propulsion energy-saving reduces discharging, and promotes air contaminant treatment, country persistently carries out
New-energy automobile popularization and application work.Pure electronic special-purpose vehicle therein, using high voltage power battery as unique energy source, by motor
Drive vehicle to travel, possess the advantages of zero-emission, low noise, can widely use in fields such as postal service, logistics, environmental sanitation, increasingly
Paid attention to by country and enterprise.Pure electronic special-purpose vehicle can be divided into shirtless equipment (as logistic car) and have upper installing standby (as ring
Defend car) two big class.Install to be divided in standby special-purpose vehicle on having again and install for the operation in stationary vehicle (as rubbish is received in requirement
Collection car) and requirement carry out operation (as road sweeper) two class in vehicle travel process simultaneously: wherein for requiring stationary deployment
More pure electronic special-purpose vehicle, it is contemplated that the factor such as exploitation, production, later maintenance, currently adopts and installs power takeoff on gearbox, from
Motor power taking provides this mode of power for upper installing is standby, and this kind of pure electronic special-purpose vehicle is only provided with a motor,
Under transport condition, motor is responsible for driving vehicle to travel, and when standby work installed by needs, controls power takeoff to engage with gearbox,
Industry part is pretended on driving；And require vehicle travel with pretend in the pure electronic special-purpose vehicle that industry is carried out simultaneously, how equipped with
Main and auxiliary two sets can independent control power drive system, wherein main power source is used for meeting the driving requirements of vehicle, and auxiliary power source is born
Install standby in duty driving.
For being only provided with a motor, need by external power takeoff on gearbox on installing standby provide dynamic
This kind of special-purpose vehicle of power, in practical operation, due to driver's maloperation, situation about also not coming to a complete stop in vehicle sometimes
Install standby in lower just starting, or in upper installing for being also not turned off just driving the situation of vehicle traveling, easily to vehicle periphery personnel
Bring potential safety hazard, accelerate the mechanical wear of vehicle interior drive disk assembly simultaneously, improve the vehicle trouble frequency of occurrences.In order to
Avoid the problems referred to above, mostly in existing power takeoff control program is as judgement bar according to parking brake signal and transmission neutral signal
Part, is controlled to power takeoff, and some can be re-introduced into accelerator pedal or brake pedal signal as auxiliary judgement condition.
But the moment of torsion due to motor, rotating speed response speed will be far faster than traditional combustion engine, and power takeoff action of putting into gear is held
Row relatively slow, using during above-mentioned power takeoff control mode it is possible to occur power takeoff put into gear complete before (gear is at a fully engaged
Before putting in place), transmission input shaft starts to rotate according to default rotating speed under the driving of motor, now power takeoff
Gear engages " beating tooth " phenomenon it may appear that different degrees of by force, gearbox, power takeoff and transmission system parts is caused rush
Hit, shorten parts service life, increased vehicle maintenance, maintenance cost, the normal use of impact vehicle.
Content of the invention

1, power takeoff gearshift execution power takeoff is put into gear action, and power takeoff gear is engaged with gearbox jackshaft, takes from gearbox
Power.Motor remains static.
2) motor is opened and is controlled: motor unlocking condition judges, according to neutral signal, GES and driving electricity
Machine tach signal judges whether to meet motor unlocking condition；After unlocking condition is set up, judged according to clutch pedal signal
Whether meet motor trigger condition；Gearbox is in neutral, stationary vehicle and motor and remains static three bars
When part is set up simultaneously, judge that motor unlocking condition is set up.After clutch pedal is operated, judges that trigger condition is set up, drive
Dynamic motor is unlocked.
3) upper installing is for the operation phase: motor is rotated with default fixed rotating speed, drives power takeoff to rotate to be dress
Equipment provides power.
4) motor closing control: include normal switching-off and abnormal close two kinds of situations, normal switching-off refer on pretend industry
After the completion of, driver's let slip the clutch, after system receives clutch pedal signal, close motor；Abnormal closing refers to
When possessing following either condition, close motor: GES is not 0km/h, gearbox leaves neutral gear position, power takeoff leaves
OFF signal is changed into logical value 0.
5) power takeoff moves back gear control: parking brake unclamps, and power take-off valve is opening, and power take-off valve signal is logical value
0, power takeoff gearshift execution power takeoff moves back gear action, and gear is separated with gearbox jackshaft.Power takeoff moves back the gear control stage
Need driver elder generation let slip the clutch, then disconnect power take-off valve.
Illustrate below in conjunction with the accompanying drawings: on a pure electric garbage collection car, for realizing described control method car load
Controller need receive signal have: power take-off valve signal, transmission neutral signal, GES, clutch state signal,
Motor actual speed signal；The control signal that entire car controller sends includes: power takeoff status signal (shows for instrument
With report to the police), motor mode control signal, motor rotating speed of target signal.
Driver drives vehicle and reaches operating location preparation collection rubbish, and after vehicle comes to a complete stop, gearbox hangs neutral, pull-up hand
Stop, press power take-off valve.The switching signal that now power takeoff gearshift receives power takeoff is logical value 1, starts to put into gear, because
Different power takeoff gearshift characteristic is different, complete to put into gear the required time also can slightly gap, but basic in 1s about just
Can complete.Driver's let slip the clutch afterwards.Be now in motor open the control stage, entire car controller according to
The GES that receives judge vehicle be in static, judge current shift according to the neutral signal receiving in neutral, according to receiving
Motor actual speed signal determining motor static.Above three condition is set up simultaneously, motor unlocking condition
Meet, entire car controller, after receiving clutch pedal signal, judges that motor trigger condition is set up, opens motor,
And send 300rpm as rotating speed of target to electric machine controller, as shown in Figure 3.After motor starts rotation, driver slowly unclamps
Clutch pedal, power is delivered to gearbox, power takeoff by motor.Power takeoff starts to rotate, and drives hydraulic pump.Rubbish
The upper installing of collecting cart is standby to adopt hydraulic control circuit, and, as power source, after setting up pressure, upper installing is for (garbage can carries for hydraulic pump
The mechanism such as rise, overturn) can start working.After the completion of refuse collection, driver's let slip the clutch, entire car controller receives
After clutch pedal signal, close motor, motor is changed into 0rpm from 300rpm, as shown in Figure 4.Now power takeoff is still
For the state of putting into gear, lift after power take-off valve after driver, power takeoff gearshift receives logical value 0, gear action is moved back in execution,
As shown in figure 5,1s about move back gear and complete.Power takeoff controls and terminates, and driver can be with normal driving vehicle to next setting.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that under the enlightenment of the present invention other are various
The product of form, however, making any change in its shape or structure, every have skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
