Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention。
The mobile terminal realizing each embodiment of the present invention is described referring now to accompanying drawing。In follow-up description, use the suffix being used for representing such as " module ", " parts " or " unit " of element only for being conducive to the explanation of the present invention, itself do not have specific meaning。Therefore, " module " and " parts " can mixedly use。
In the system having grade gear shift, include but not limited to mechanical automatic gearbox (AutomatedMechanicalTransmission, AMT), double clutch gearbox (DualClutchTransmission, DCT) etc.。Inventor finds under study for action, in the shifting up operation of ATM or DCT, also has the third energy to reclaim。When upshift, the rotating speed of output shaft of gear-box the same with speed can be considered constant, and in order to meet the requirement after upshift, its power shaft must reduction of speed。For the system with clutch, after clutch is opened, the inertia of power shaft is only small, and the kinetic energy of storage is also only small, and speed can lower quickly, and the meaning of generating is also just little。But for fixing pure electric vehicle or the hybrid dynamic system of connection with motor, the inertia of rotor is relatively larger, the energy of storage also just compares many, in addition gear number is generally fewer, so the speed difference that during upshift, needs reduce can be relatively larger, this part of energy be used for generating and recovery just becomes highly significant。
The present invention proposes the control method that a kind of automobile energy reclaims, and refers to Fig. 1, and method flow includes:
S101, judge whether change speed gear box performs upshift and pluck shelves, if performing step S102；
S102, control motor enter generating state；
S103, monitor this change speed gear box synchronous rotational speed difference whether in default scope, if perform step S104, otherwise perform step S105；
S104, stopping generating, control change speed gear box execution extension shelves and operate；
S105, main power source is carried out synchronous variable-speed so that this synchronous rotational speed difference reach this preset scope so that the kinetic energy of the transmission input shaft of this motor of battery recycling and possible configuration, wherein this main power source is this motor。
In practical application, in the AMT system having clutch, synchronization is implemented to synchronize after clutch separation, and after clutch separation, the rotary inertia of power shaft is only small, because only that the gear of the clutch plate of clutch, power shaft and connection thereof。For electric motor car or hybrid electric vehicle, what power shaft connected is more than gear, also has the rotor driving motor, and motor rotor is that a big metal derby is made, and its rotary inertia is much larger than the former gear。This rotor speed regulation is not easy to by the lock unit depended merely on change speed gear box。Good aspect be motor can speed governing, lock unit therefore can not be leaned on to drive, and rely on motor self to drive and synchronize, as long as electric machine speed regulation response is fast and accurately, it becomes possible to realize synchronization。Therefore, in theory, in the present embodiment, the synchronous ring on the lock unit of the change speed gear box of electric motor car is not necessarily。
In gearshift procedure, plucking before and after shelves, namely motor control unit makes motor be in generating state immediately, and the size of generated energy is determined by the rotating speed of motor and the difference of rotating speed of target and desirable speed reducing ratio。Although, after plucking shelves, motor shaft and wheel are separated, the rotating speed of motor no longer affects speed, but the sharply change of motor speed can make motor produce to impact, and this impact can affect the life-span of motor, also suitable prompt drop can be delivered to vehicle body and cause vibration, so should be selected。The adjustment of prompt drop speed is to be completed by the size of adjustment generated energy。Generated output is more big, and severity of braking is also more severe, and vice versa。When motor speed is close to desired speed, generating should be slowed down in case prompt drop is excessive, try to be clever only to end up with a blunder。
The control method that the automobile energy of this enforcement reclaims, it is possible to get up the energy storage that change speed gear box produces in shifting up operation to rise after completing for gear shift and turn round required electric energy, it is possible to increase efficiency, save energy consumption。What is more important, the recovery of this energy accelerates the prompt drop of motor and the time shortening synchronization needs, and acceleration shifting process, shortening power interruption time, raising system rapidity are had very positive meaning。
On the basis of above-described embodiment, the present invention further provides the control method that a kind of automobile energy reclaims。Clutch is needed for hybrid power, but clutch is avoided the need for for pure power driven system, be also just absent from opening clutch and closing two actions of clutch in tradition AMT。In electric motor car, the whole gearshift procedure of AMT can be reduced to and drop torsion, plucks shelves, synchronization, extension shelves, rises and turn round five steps。Wherein drop torsion, pluck shelves, hang shelves, to rise four steps such as torsion basic and AMT gear shift in traditional vehicle is similar。Only synchronize there is relatively big difference。As in figure 2 it is shown, method flow includes:
S201, judge whether gear shift, if performing step S202, otherwise properly functioning；
S202, torsion is dropped；
S203, judge output moment of torsion whether in preset range, if perform step S204, otherwise continue executing with step S202;
S204, pluck shelves；
S205, gear selecting；
S206, judge synchronous rotational speed difference whether in default scope, if perform step S207, otherwise perform step S210；
S207, extension shelves, and perform step S208；
S208, liter are turned round。
S209, judge output moment of torsion whether in preset range, otherwise continue executing with step S208；
S210, main power source is carried out synchronous variable-speed and carries out energy regenerating。
In said method flow process, step 209 can realize in the AMT energy recovery module controlling to increase in logic。The control method that the automobile energy of this enforcement reclaims, it is possible to get up the energy storage that change speed gear box produces in shifting up operation to rise after completing for gear shift and turn round required electric energy, it is possible to increase efficiency, save energy consumption。What is more important, the recovery of this energy accelerates the prompt drop of motor and the time shortening synchronization needs, and acceleration shifting process, shortening power interruption time, raising system rapidity are had very positive meaning。
In shifting up operation, owing to motor needs quickly to carry out synchronous variable-speed, electric machine controller can provide a braking torque and go to control electric machine speed regulation, so electric current easy moment produced by motor reaches a higher value in the meantime, scope even up to hundreds of ampere, likely beyond the strength of charging current of battery, cause the infringement to battery。For a firm fully charged battery, gear shift is reclaimed the electric energy of motor generation and motor will be made to overcharge, and battery life will also result in certain impact。
Therefore; it is improper to control if recovered energy; instead result in the ill effects such as cell damage; solution can optimize battery energy management strategy on the one hand; select to reclaim, under protection battery precondition, the part electric energy that gear shifting motor produces; do not reclaim when electricity full of battery, now will synchronize with lock unit。Therefore, in order to protect battery, it is possible to increased following steps before the step S102 of method shown in Fig. 1, refer to Fig. 3, it is shown that step includes:
S301, calculate speed error according to the desired speed of this motor and actual speed；
Concrete, this step includes:
Table look-up acquisition desired speed；
Check actual speed；
Calculate speed error。
S302, judge that according to speed error whether this motor speed is more than preset value, if so, perform step S303, otherwise, perform step S307。
S303, calculate the generated output of this motor according to pid algorithm；
S304, judge according to this generated output battery whether can reclaim this motor produce whole electric energy, if perform step S306, otherwise perform step S305；
S305, control change speed gear box realize synchronizing by lock unit；
S306, execution control motor and enter the step of generating state。
S307, carry out Min self study。
In practical application, it is also possible to by increasing energy storage device, for instance super capacitor, battery is protected。Energy storage device can be exclusively used in and reclaim the energy regenerating including brake, descending, gear shift。As long as coordinating motor to control the Energy harvesting with energy storage device, the energy that motor in gearshift procedure is produced reclaims, and is greatly improved the utilization rate of electric energy surely, thus improving the course continuation mileage of electric motor car。
