Line.
In addition, with reference to shown in Fig. 3, the motor M2 of each sampling instant can generated output and the chargeable power of battery ask small,
The as chargeable power of motor M2, corresponding power generation torque, every speed under each rotating speed can be obtained by chargeable power
Lower engine Best Economy curve corresponds to torque and subtracts power generation torque, as driving power generation curve.Wherein, driving power generation region
Also to ensure that engine is in high efficient district, which refers in Fig. 3 between 1500~4500r/min, bd and driving power generation curve
Between region.
In an embodiment of the present invention, it is first determined engine high-efficiency curve, power generation cascade curve, engine optimal economic
Linearity curve, driving power generation curve, to consider engines fuel-economizing effect and power consumption, propose that engine drive mode and driving are sent out
The division methods of power mode, and given engine driving and driving power generation mode critical line computational methods, determine work in real time
Pattern, and the control method of each parts target torque.
S103, compares demand torque and engine high-efficiency driving torque and motor driving power generation torque.
S104, if demand torque is greater than or equal to engine high-efficiency driving torque, control vehicle drives into engine
Dynamic model formula.
Wherein, in one embodiment of the invention, when demand torque is corresponding equal to engine high-efficiency area critical curve
During engine high-efficiency driving torque, the energy expenditure of engine drive mode is identical with the energy expenditure for power generation mode of driving a vehicle.
S105, if SOC is less than preset value, demand torque is less than engine high-efficiency driving torque and is sent out more than motor driving
Electric torque, then control vehicle to enter driving power generation mode.
Further, in one embodiment of the invention, the above method further includes：Series connection hair is respectively obtained according to rotating speed
The corresponding power generation cascade torque of electric curve；Compare demand torque and power generation cascade torque and the product of electric efficiency；If demand

Further, in one embodiment of the invention, the above method further includes：Obtained according to rotating speed special outside engine
The corresponding engine maximum driving torque of linearity curve；Compare demand torque and engine maximum driving torque；If demand torque
Less than engine maximum driving torque, then vehicle is controlled to enter engine drive mode；If demand torque is more than engine most
Big driving torque, then control vehicle to enter combination drive pattern.
Specifically, in one embodiment of the invention, operating mode and drive pattern division are secondly carried out.
With reference to shown in Fig. 4, when vehicle enters electricity supplemental stages, SOC is less than preset value, that is, desired value, and there are operating mode
And priority, as shown in the figure, engine drive mode is preferentially used, and specifically, the preferential hair used in engine drive mode
Motivation high effective model, engine works in high efficient district under the pattern, and avoids and turn between mechanical energy-electric energy-mechanical energy
Change, be optimal whole system efficiency；Secondly driving power generation mode priority is taken second place, demand torque is smaller under the pattern,
Using the control method of driving power generation, engine works in optimal fuel economy curve, and part driving vehicle forward is another
Part is used for electric power generation；It is finally power generation cascade pattern, due to there are mechanical energy-electric energy-mechanical energy, causing system effectiveness
It is relatively low, it is all in the relatively low slow-speed of revolution of engine efficiency or low torque operating mode uses, engine works in Best Economy work at this time
Make a little.
Further, in one embodiment of the invention, motor includes the first motor such as motor M1 and the second motor such as
Motor M2, the power of the first motor are less than the power of the second motor, after control vehicle enters driving power generation operation pattern, on
The method of stating further includes：Torque, the power generation torque of corresponding first motor of rotating speed and the power generation torque of the second motor are sentenced according to demand
It is disconnected to provide driving power generation by the first motor or the second motor.
Specifically, method for controlling torque comprises the following steps：
S1, inputs real-time demand torque Tr and rotating speed n, and Tr refers to that demand torque is converted to main reducing gear input at wheel
The torque at end, n refer to the rotating speed of main reducing gear input terminal.
S2, according to n, pure engine and driving power generation critical line, that is, engine high-efficiency area critical curve (bd), interpolation determines
Go out n in the corresponding engine high-efficiency driving torque Te_d of bd lines.
S3, according to n, driving power generation curve and engine optimal economic linearity curve, interpolation determines n in driving power generation curve
Corresponding motor driving power generation torque T_c, the corresponding engine Best Economy torque Te_o of engine optimal economic linearity curve；
Motor M1 and the chargeable power of battery take small, according to n, can obtain motor M1 and correspond to charge torque T_c1；
S4, according to n and power generation cascade curve, interpolation determines n in the corresponding power generation cascade torque T_ of power generation cascade curve
S, and power generation cascade curve rotating speed n_op and torque T_op corresponding with engine Best Economy intersections of complex curve.
Wherein, in one embodiment of the invention, Te, Tm1 and Tm2 represent motor torque, motor M1 and motor M2
Target torque, ne represent engine rotating speed of target.Further, with reference to shown in Fig. 5, engine, motor M1 and motor M2
Specific control method comprise the following steps：
1) judge whether Tr is more than Te_d, if so, engine is in high efficient district, Te=Tr, Tm1=0, Tm2=at this time
0, at this time driving torque be provided separately by engine, avoid the energy loss between the conversion of energy under other patterns.
2) above condition if not, judging whether Tr is more than whether T_c and Tr are less than Te_d, if so, vehicle work at this time
Make in power generation mode of driving a vehicle；When Tr-Te_o meet less than or equal to T_c1 conditions, Te=Te_o, Tm1=Te_o-Tr, Tm2=
0, driving power generation is completed by motor M1 at this time, since motor M1 power is small, efficient, so preferentially being used during driving power generation；When
When Tr-Te_o are unsatisfactory for less than or equal to T_c1 conditions, Te=Te_o, Tm1=0, Tm2=Te_o-Tr, motor M2 complete driving hair

3) when Tr be more than T_c and Tr be less than Te_d conditions for it is no when, determine whether Tr is less than T_s × motor effect
Rate, if so, vehicle is in power generation cascade pattern, ne=n_op, Tm1=Te_op, Tm2=Tr at this time, motor uses torque control
System, engine use method for controlling number of revolution, motor M1 is worked in engine Best Economy and power generation cascade intersections of complex curve, carry
High engine operating efficiency.
4) above condition if not, judging whether Tr is less than engine maximum driving torque Tm, if so, at this time by starting
Machine is operated alone, i.e., vehicle enters engine drive mode, Te=Tr, Tm1=0, Tm2=0.
5) above condition if not, vehicle enters combination drive pattern, Te=Tm, Tm1=0, Tm2=0.
The control method of the embodiment of the present invention has considered engines fuel-economizing effect and power consumption factor, it is proposed that engine
