Operation is intended to.
Step (3), gearbox control TCU is intended to according to the operation of driver and whole vehicle state calculates pure electric automobile
Best power performance and Best Economy shift schedule, determine car load rational state and optimal gear;
Best power performance shift schedule:
Power performance optimal under dynamical state to be ensured, it should with the speed that adjacent two grades of accelerating curve intersection points are corresponding
As power gears-shifting point, i.e. need to meet:
In formula, u-electric automobile max. speed, the t-electric automobile acceleration time;
According to running car equation, have when n shelves:
Wherein, δn-drive system rotating mass inertia factor, the gross mass (kg) of m-electric automobile, Tq-electromotor is special
Property, io-speed ratio of main reducer, ignThe gear ratio of-variator n shelves, ηT-transmission system efficiency, the rolling radius (m) of r-wheel,
G-acceleration of gravity (m/s2), CD-coefficient of air resistance, f-coefficient of rolling resistance, A-front face area (m2), ua-best power performance
Shift points;
Simultaneous formula (1) and formula (2) just can try to achieve best power performance shift points ua。
Best Economy shift schedule:
From the consumption angle analysis of energy, in vehicle traveling process, the energy of battery is mainly used to eliminate the traveling resistance of automobile
Power and the dissipation of heat, if total energy of battery storage is W, then have:
W·ηb·ηe·ηT=∑ F L (3)
In formula, all external resistance sums (N) being subject in ∑ F-vehicle traveling process, the continual mileage of L-electric automobile
(m), ηbThe efficiency of-power battery pack, ηeThe efficiency of-driving motor and controller, ηT-transmission system efficiency.
From formula (3) it can be seen that at electrokinetic cell and drive system it has been determined that in the case of, its respective efficiency is basic
Constant, uniquely affect the efficiency (under be called for short electric efficiency) driving motor and its controller exactly of distance travelled.Pure electronic vapour
The formulation of the economy shift schedule of car is with the transmission efficiency of motor as foundation, it is ensured that motor always works in possible the highest
Effect district.It is principle to the maximum, if the electric efficiency of i.e. current gear is less than down with the electric efficiency of adjacent two grades under a certain throttle
The efficiency of one gear, then now speed is exactly Best Economy shift points.
Owing to the running environment of electric automobile is complicated and changeable, only do not adapted to by the shift schedule meeting single road conditions
Requirement to gear under the various operating mode of automobile, this change being accomplished by identifying running environment, in order to carry out dynamically shift schedule
Correction, reach to meet the purpose of vehicle overall performance.
Vehicle load changes the impact on shift schedule the most greatly:
In formula, uzElectric automobile max. speed (m/s), F during-zero loadL-vehicle load (N), Ft-Current vehicle driving force
(N), FfZ-zero load condition resistance to rolling (N), FwZ-zero load condition air drag (N);
Power gears-shifting rule is with FLIt is that under zero premise, adjacent two grades of acceleration are equal to calculate for condition, works as FLNo
When being zero, from formula (4), if still using the speed under zero load condition as shift points, the most calculated acceleration will
The most equal, acceleration difference is:
From formula (5) it can be seen that FLThe biggest, the change of gear shift post-acceleration is the biggest, especially going up a slope when, and vehicle
Power performance will be greatly reduced after gear shift.After dynamic property upshift, the driving force of new gear is less than the driving force of former gear, if FL
Value be just met for reaching gear shift speed, i.e. gear shift brief acceleration at this gear being zero, then will be negative at gear shift post-acceleration
Value, vehicle drive force deficiency reduces speed now travelings, if ramp long enough, after reducing to downshift point downshift, driving force recovery, again can
Process before repetition, causes gear shift to circulate, greatly reduces riding comfort.If automobile is to change with economy on ramp
Shelves rule travels, and it will be bigger that gear shift post-acceleration becomes the probability of negative value.
On the other hand, for loading automobile based on the automatic speed-changing system driving motor active synchronization at upper relatively steep gradient
Time should avoid gear shift, this is because, this automatic speed-changing system has the power interruption of short time in gearshift procedure, if ramp
Resistance is excessive, and speed can decline quickly, affects shift property.
The load value of vehicle directly can be tried to achieve according to formula (6),
FL=Ft-(FfZ+FwZ+FjZ) (6)
In formula, FjZ-zero load condition acceleration resistance (N);
During actual application, the implementation method of remained capacity can be divided into two kinds of sides according to the difference calculating parameter acquiring approach
Method, the first is the vehicle parameter being brought directly under zero load condition, then have:
In formula, TuMotor torque under-current vehicle speed, igThe gear ratio of a certain shelves of-variator, mZ-empty mass (kg);
When wherein Motor torque can be travelled by vehicle, the torque feedback of motor obtains in real time, and acceleration needs to carry out speed
Calculus of differences obtains, in this manner it is possible to the vehicle load calculated under any speed.This method implements and is easy to, but by
In the difference of vehicle parameter Yu practical situation, to expect and load change really, the order of accuarcy of parameter is required the highest.
The second is to be obtained by experimental calibration to calculate parameter.From formula (7), vehicle load FL and Motor torque, car
Speed and the change of acceleration are relevant, can be reduced to the form of following formula:
If making automobile maintain certain speed u under zero load conditionaAt the uniform velocity travel, can obtain following formula:
0=aTua-b-cua 2 (9)
It can be seen that now speed uaWith corresponding motor torque TuaFor definite value, this formula is the ternary about coefficient a, b, c
Linear function, according to said method, obtains the equation of more than 2 groups, just can obtain the value of a, b, c, by increasing sampled point and experiment time
Number, can be close to actual value.After a, b, c determine, give it the gun with certain acceleration under zero load condition equally, ask for
Parameter d, chooses many group sampled points to be close to actual value.After all parameter determinations, can be single on the basis of zero load condition
Increasing constantly acting load or choose the road of the fixing gradient and test, the vehicle load that checking is identified is consistent with practical situation
Property.The calculating parameter that this method is tried to achieve is closer to truth, and can carry out in the case of to vehicle parameter the unknown
Remained capacity, but higher to the code requirement of experiment, especially ensure the state that at the uniform velocity travels of vehicle it is difficult to ensure that.
Actual realize remained capacity time, two kinds of methods can be combined it, first pass through parameter and calculate and obtain initial ginseng
Number, is being modified it by experiment, and the accuracy of proof load identification.
Step (4), suitable opportunity gearbox control TCU gearshift request, Shifting meeting can according to circumstances be proposed
Judge according to practical situation;
Step (5), if can shift gears, gearbox control TCU uses CAN communication mode to electric machine controller MCU
Sending instruction, motor reduces moment of torsion, and neutral hung by gearshift;
Step (6), during until motor speed is consistent with change speed gear box rotating speed, shelves hung by gearshift, and gearshift completes, and motor is the most extensive
Multiple moment of torsion.
According to new-energy automobile automatic transmission power shifting control method of the present invention, with Traditional control process ratio
More as shown in Figure 6;By input torque controls to reduce the fluctuation of output moment of torsion, improve shifting comfort;Can from Fig. 6
Going out the progressive process of process for gear, the output torque ripple in Fig. 6 (c) is straight line, fluctuates the least, the comfortableness of gearshift
High.
Detailed description of the invention is described in detail above according to technical scheme.Exist according to technical scheme
Do not change under the connotation of the present invention, the various structures mode that one of ordinary skill in the art can mutually can be replaced with proposition
And implementation.Therefore, above-described detailed description of the invention and accompanying drawing are only the examples to technical scheme
Property explanation, and be not to be construed as the whole of the present invention or be considered as technical solution of the present invention is defined or limited.
