(5) one grade of transmission mode of driving engine.Along with the lifting of the speed of a motor vehicle, energy flow between speed discrepancy and two motors of double-rotor machine 4 inner and outer rotors reduces gradually, planet row I 3(is containing planet row II 5) sun wheel I 32 rotating speeds promote gradually, and gear ring I 33 rotating speeds of planet row I 3 decline gradually, in the time that both approach synchronous speed, double-rotor machine 4 proceeds to electronic stall (naturally synchronous) mode by generation mode and works, planet row I 3 is by locking, form one grade of transmission mode, system relies on the power of mechanical system transmission driving engine 1 completely, thereby improves energy driving efficiency.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 5.
(6) series-parallel connection driven at low speed pattern two.Under one grade of transmission mode, along with the further lifting of the speed of a motor vehicle, driving engine 1 departs from economical operation region gradually, and at this moment double-rotor machine 4 turns mode of operation from electric block and exits, 3 releases of planet row I, system switches to this series-parallel connection driven at low speed pattern from one grade of transmission mode.When the speed of a motor vehicle promotes gradually, torque-demand reduces gradually, now, main motor 6 is with generation mode work (attempt to stop sun wheel II 52 turn round/subtract square), electric energy flows to double-rotor machine 4 through main electric machine controller 12, double-rotor machine controller 11, double-rotor machine 4 inner and outer rotors in reverse electronic mode to the work of changing a job (attempting to stop engine running/speedup), series-parallel connection low-speed mode subtracts square speedup, planet row II 5 continues to slow down and increase square with i1 transmitting ratio, outputs driving force to main reduction gear 8 and drives vehicle.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 6.
(7) driving engine second gear transmission mode.Under series-parallel connection driven at low speed pattern, along with the further lifting of the speed of a motor vehicle, pinion carrier II 51 rotating speeds of planet row II 5 raise gradually, and planet row I 3 inner and outer rotors to the drive turning under, sun wheel I 32 rotating speeds rise gradually, gear ring I 33 rotating speeds decline gradually, in the time that the gear ring I 33 of planet row I 3 approaches synchronous speed with the pinion carrier II 51 of planet row II 5, power-transfer clutch C1 engages, and forms second gear transmission mode, and now the power of driving engine 1 drives wheel with mechanical drive mode again completely.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 7.
(8) series-parallel connection high-speed driving pattern one.Under second gear transmission mode, along with vehicle speed-raising, the operation point of driving engine needs again to adjust, and adjustment mode is only the power-transfer clutch C2 under second gear transmission mode to be separated, and maintains power-transfer clutch C1 and engages.Now system will enter this series-parallel connection high-speed driving pattern, and its principle is similar to " series-parallel connection driven at low speed pattern ", and difference is: one, and double-rotor machine 4 is with generation mode antiport together with planet row I 3; They are two years old, the torque after double-rotor machine decoupling zero of the mechanical horsepower of driving engine sees through, and be transmitted to the pinion carrier II (transition gear 7/ transmitting ratio i3) of planet row II 5 through power-transfer clutch C1 by outer rotor 42 and gear ring I 33, directly drive vehicle through main reduction gear, diff; Its three, main motor continues to slow down and increase square and participate in driving vehicle with i1 transmitting ratio.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 8.
(9) driving engine third gear transmission mode.Vehicle is during with series-parallel connection high-speed driving mode operation, along with the continuation of the speed of a motor vehicle is risen, gear ring I 33 rotating speeds of planet row I promote gradually, sun wheel I 32 rotating speeds decline gradually, in the time that both approach synchronous speed, double-rotor machine 4 proceeds to electronic stall mode by generation mode and works, and planet row I 3 is by locking, form third gear transmission mode, i.e. direct speed; System is when third gear drives, and drg B separates, and power-transfer clutch C2 engages, and planet row II 5 is same by locking.These shelves are also for high-performance cruise, and by the auxiliary power-assisted of main motor 6 or driving charging.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 9.
(10) series-parallel connection high-speed driving pattern two.Under third gear transmission mode, when vehicle raises speed again, driving engine 1 raises speed thereupon.In the time that driving engine 1 operation point no longer includes high efficiency requirement, double-rotor machine 4 exits electric block and turns mode of operation, planet row I 3 releases (planet row II 5 is followed release), power-transfer clutch C1, power-transfer clutch C2 maintain joint, drg B maintains separation, and system switches to this series-parallel connection high-speed driving pattern from third gear transmission mode.Under this pattern, an outputting power part for driving engine 1 by double-rotor machine 4 inner and outer rotors with oppositely electronic to turning pinion carrier II 51 and transition gear 7 transferring power (torque M 1) of mode to planet row II 5, another part is divided into again the power (torque T2) that the pinion carrier II 51 of direct driving planet row II 5 and the mechanical power of transition gear 7 (torque T1) and the main motor 6 of driving are generated electricity, and its electric energy flows to double-rotor machine 4 through main electric machine controller 12, double-rotor machine controller 11.Torque under this pattern (cireular frequency) lever simulated diagram in detail as shown in Figure 10.
Wherein, T0=M3+T3 M3=M1=-M2 × (1ZR+1ZS)/1ZS
T3＝T1＋T2 T＝T1＋M1
In formula: T0 motor torque, the reverse electronic torque of-M2, T3 input distribution of torque, the torque of T power take-off shaft
If disregard system loss T2 ω 2=M1 ω 1 ' T2 ω 2 and M1 ω 1 ' for generating with electronic between the electric power of transmission.
Under this pattern, when T0 mono-timing, if will continue speed-raising, need reduce ω 2 and strengthen ω 1 ', certainly will strengthen like this T2, reduce M1; So, speed-raising process is that T3 increases gradually, the process that M3 reduces gradually, and the increasing of T2, M1 reduces, impel sun wheel I 32 rotating speeds of planet row I 3 to decline, gear ring I 33 rise of rotational speed, torque T reduces, driving engine 1 power flow direction gear ring (T1 ω 1), automobile enters high-speed cruising, and now output speed is greater than engine speed.
(11) driving engine fourth gear transmission mode.Automobile is at two times high-speed cruising of series-parallel connection high-speed driving pattern, along with the continuation speed-raising of vehicle, in the time that sun wheel I 32 rotating speeds of planet row I 3 approach zero, main motor 6 proceeds to electronic stall mode from generation mode and works, through the sun wheel I 32 of the fixing planet row I 3 of power-transfer clutch C2, form fourth gear transmission mode, i.e. high range overdrive gear.These shelves are also for high-performance cruise, and by the auxiliary power-assisted of double-rotor machine 4 or driving charging.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 11.
(12) aero mode.Vehicle (system) is operated in anxious acceleration the under series-parallel connection low speed, series-parallel connection high-speed driving pattern or driving engine transmission mode:
(12.1) in the time that double-rotor machine 4 is worked with generation mode, except improving driving engine 1 horsepower output, electrokinetic cell 13 also provides extra power to main motor 6, and at this moment the gross output power of vehicular transmission shaft is: the electric power that the electric power+electrokinetic cell transmitting between mechanical horsepower+two motor directly transmitting by double-rotor machine 4 provides main motor; Wherein electrokinetic cell 13 provides instantaneous acceleration power, driving engine 1 horsepower output rising.
(12.2) in the time that double-rotor machine 4 is worked in electronic mode, except improving driving engine 1 horsepower output, main motor 6 is generated electricity/is proceeded to electronic by generation mode/exit, electrokinetic cell 13 not only improves extra power to double-rotor machine 4, also provides extra power to main motor 6.
(12.3) in the time being operated in high-speed driving pattern two, except improving driving engine 1 horsepower output, main motor 6 continues to provide electric power with generation mode to double-rotor machine 4, and 13 of electrokinetic cells provide extra power to double-rotor machine 4.
(12.4), in the time being operated in driving engine transmission mode, except improving driving engine 1 horsepower output, electrokinetic cell 13 also provides auxiliary power to main motor 6 or double-rotor machine 4.One assists power-assisted to third gear by main motor 6, and fourth gear is by the auxiliary power-assisted of double-rotor machine 4.
(13) braking energy feedback pattern.When car retardation or braking, in the case of the SOC of electrokinetic cell 13 allows, vehicle energy is worked in electrical generator mode by the main motor 6 of drive wheel or double-rotor machine 4, and kinetic energy is converted to electric energy, charges to electrokinetic cell 13; The drive pattern that the utility model is corresponding different and the corresponding speed of a motor vehicle have three kinds of energy feedback mode of operations, and under each pattern, electrical generator all can obtain higher rotating speed, make energy feedback more fully with efficient.
(13.1) when system works is the independent drive pattern of main motor 6 (power-transfer clutch C1 separates) with below second gear transmission mode time, driving engine 1 quits work, double-rotor machine 4 is with electrical generator mode feedback energy, and now main motor 6 dallies, and is low-speed mode energy feedback one.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 12.
(13.2) in the time that system works is between second gear transmission mode and third gear transmission mode (before planet row I 3 and the common locking of planet row II 5), driving engine 1 quits work, main motor 6 is with electrical generator mode feedback energy, and now double-rotor machine 4 dallies, and is low-speed mode energy feedback two.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 13.
(13.3) when system works is at third gear transmission mode and when above, double-rotor machine 4 exits electric block and turns mode of operation, planet row I 3 and the natural release of planet row II 5, and now power-transfer clutch C1, power-transfer clutch C2 maintain joint, and drg B maintains separation.When vehicle reduces speed now from fair speed, because being subject to double-rotor machine 4 rotating speed restrictions and protection planet row, driving engine 1 work at a predetermined velocity (rotating speed slow falls), under the common coordination of the speed of a motor vehicle, engine speed and planet row I 3, between double-rotor machine 4 inner and outer rotors, there are enough speeds discrepancy to generate electricity and energy feedback; Along with the further decline of the speed of a motor vehicle, engine stop work, continues the certain speed discrepancy of maintenance between inner and outer rotors, and in this process, main motor idle running, is fast mode energy feedback.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 14.
14, reversing mode of operation.In the time that electrokinetic cell 13SOC is in range of normal value, main motor 6, as electrical motor reversion work, drives vehicle backing; In the time that SOC drops to setting value, fire an engine 1, drives the outer rotor generating of double-rotor machine 4, and the electric energy of generation flows to main motor 6 through double-rotor machine controller 11, main electric machine controller 12, and main motor 6 is with the electronic mode driving vehicle backing that reverses.Speed under this pattern (rotating speed) lever simulated diagram in detail as shown in Figure 15.
To sum up, the groundwork mode list of native system is as follows:
As mentioned above, just can well realize the utility model.
