The six modes of operation of power drive system 100 are described separately below.

First electric-only drive mode (EV1 mode): in the power drive system 100, in the first pure electric drive mode, the first ring gear 31 is not in transmission connection with the second carrier 44 and the second carrier 44 is locked, the second power source 7 is in an operating state, the third power source 5 and the first power source 6 are in an inactive state, at this time, the second power source 7 outputs power to the second planetary gear mechanism 4 through the second sun gear 43, then the power is transmitted to the third gear 77 through the second ring gear 41 of the second planetary gear mechanism 4, the final power is transmitted to the wheels, the vehicle is driven to run, and part of the power generated by the second power source 7 can also be transmitted to the first carrier 34 of the first planetary gear mechanism 3 through the second ring gear 41 of the second planetary gear mechanism 4, and part of the power transmitted to the first carrier 34 is transmitted to the first power source 6 through the first sun gear 33 of the first planetary gear mechanism 3, the first power source 6 is brought into a follow-up state, and the other part of the power transmitted to the first carrier 34 of the first planetary gear mechanism 3 is transmitted to the third power source 5 through the first ring gear 31 of the first planetary gear mechanism 3, and the third power source 5 is kept in a stopped and stationary state because the third power source 5 itself has a large damping torque. When the vehicle is in first pure electric drive mode, the pure electric drive alone of second power supply 7, first power supply 6 does not provide effective driving torque, but first power supply 6 is in along with the commentaries on classics state, and first pure electric drive mode is applicable to the pure electric driving operating mode of well low load.

Second electric-only drive mode (EV2 mode): in the second pure electric drive mode of the power drive system 100, the third power source 5 is in an inactive state, the first ring gear 31 is in transmission connection with the second carrier 44 and the locking device 9 locks the second carrier 44, and the first power source 6 and/or the second power source 7 are in pure electric drive, it can also be understood that the first power source 6 and/or the second power source 7 are in an active state, for example: the first power source 6 and the second power source 7 are both in an operating state in which the power generated by the second power source 7 can be transmitted to the second sun gear 43 of the second planetary gear mechanism 4, the second carrier 44 is in a locked state, the power generated by the second power source 7 can be transmitted to the third gear 77 through the second ring gear 41 of the second planetary gear mechanism 4, the power generated by the first power source 6 can be transmitted to the second planetary gear mechanism 4 sequentially through the first sun gear 33 and the first carrier 34 of the first planetary gear mechanism 3, and then the power generated by the first power source 6 can be transmitted to the third gear 77 through the second ring gear 41 of the second planetary gear mechanism 4, so that the torque of the first power source 6 and/or the second power source 7 can be output to the second ring gear 41 of the second planetary gear mechanism 4 through respective independent fixed gear ratios, then from second ring gear 41 transmission to third gear 77, the drive vehicle goes, because first power supply 6 and second power supply 7 can provide driving torque simultaneously, the bi-motor is for satisfying whole car traction torque matching demand reduction, be favorable to reducing the volume and the weight of motor, thereby can reduce bi-motor system cost, the pure electric drive mode of second can adapt to the light load of vehicle under pure electric drive mode or the heavy driving operating mode of heavy load, and power drive system 100 can effectively reduce the heat loss of vehicle under the working condition of staying slope or low speed climbing under the pure electric drive mode of second.

First infinitely variable speed series-parallel hybrid drive mode (eCVT1 mode): the first ring gear 31 is not in transmission connection with the second carrier 44, and the locking device 9 locks the second carrier 44, specifically, when the connection state of the first ring gear 31 and the second carrier 44 and the working state of the locking device 9 are completely the same as those of the first ring gear 31 and the second carrier 44 and the working state of the locking device 9 in the first pure electric drive mode, the power drive system 100 can smoothly switch between the first pure electric drive mode and the first stepless speed regulation hybrid drive mode. The first stepless speed regulation hybrid driving mode is an input type power splitting hybrid driving mode, the first power source 6 can split speed power, the third power source 5 provides power input, the power generated by the third power source 5 is transmitted to the first sun gear 33 of the first planetary gear mechanism 3, then a part of the power generated by the third power source 5 is transmitted to the second planetary gear mechanism 4 through the first planet carrier 34 of the first planetary gear mechanism 3, the power is transmitted to the third gear 77 through the second ring gear 41 of the second planetary gear mechanism 4, another part of the power generated by the third power source 5 is transmitted to the first power source 6 through the first sun gear 33 of the first planetary gear mechanism 3, the speed regulation power is split through the first power source 6, specifically, if the power splitting power of the third power source 5 by the first power source 6 is negative, the first power source 6 converts another part of the power of the third power source 5 into electric power for power generation, if the power split power of the first power source 6 to the third power source 5 is positive, the first power source 6 consumes the electric quantity of the vehicle-mounted power battery, meanwhile, the second power source 7 provides additional driving torque according to a fixed speed ratio to balance the electric quantity of the battery, or discharges the vehicle-mounted power battery to provide additional accelerating power, the driving torque provided by the second power source 7 is amplified according to the fixed speed ratio and then is transmitted to the second ring gear 41 of the second planetary gear mechanism 4, and after linkage with the power output of the third power source 5 transmitted to the second ring gear 41 of the second planetary gear mechanism 4, the power is transmitted to the third gear 77 through the first gear 55 and the second gear 66, and finally the power is transmitted to the wheels through the third gear 77. The first stepless speed regulation hybrid driving mode can enable the third power source 5 to always keep the best working efficiency and reduce the energy consumption of the vehicle, and is mainly applied to the driving working condition from medium-load to heavy-load at medium and low vehicle speeds.

In the first engine direct drive mode (FG1 mode), the first engine direct drive mode (parallel hybrid with a fixed gear ratio) is that in the first stepless speed regulation hybrid drive mode, the first power source 6 is regulated to zero speed to lock the first power source 6, so that the power splitting effective power of the first power source 6 to the third power source 5 is zero, at this time, the power generated by the third power source 5 can be completely transmitted to the second ring gear 41 of the second planetary gear mechanism 4 through the first carrier 34 of the first planetary gear mechanism 3, then the power generated by the third power source 5 can be transmitted to the third gear 77 through the second ring gear 41, and then the power can be output to the wheels from the third gear 77, in this state, the power transmission efficiency of the third power source 5 is optimal, and in this state, the power generated by the second power source 7 and the power of the third power source 5 can be directly output after being connected in parallel with the second ring gear 41 of the second planetary gear mechanism 4, therefore, the first engine direct-drive mode is more suitable for coping with the driving conditions of the vehicle under the medium-low speed and medium-high continuous steady-state load.

Second continuously variable speed series-parallel hybrid drive mode (eCVT2 mode): the first ring gear 31 is in driving connection with the second planet carrier 44 and the locking device does not lock the second planet carrier 44. The third power source 5, the first power source 6 and the second power source 7 work simultaneously through the first planetary gear mechanism 3 and the second planetary gear mechanism 4 to realize compound power-split stepless speed-regulating hybrid, and power is finally input to the third gear 77 through the second ring gear 41 of the second planetary gear mechanism 4, and the final power can drive the vehicle to run. It should be noted that, in the second stepless speed regulation hybrid driving mode of the power driving system 100, both the first power source 6 and the second power source 7 can be used as speed regulation power split motors, but the first power source 6 or the second power source 7 cannot operate in the speed regulation power split mode at the same time, otherwise, the lever balance mechanism formed by combining the two planetary gear mechanisms together is broken. In the second stepless speed regulation hybrid driving mode, when the first power source 6 is used as a speed regulation power shunt motor, the second power source 7 can be used as a driving motor to drive the vehicle to run together with the third power source 5. The fixed transmission ratio of the mechanical transmission path of the third power source 5 is defined as a first gear shifting ratio of the second stepless speed regulation hybrid drive mode, a first mechanical gear shifting point of the second stepless speed regulation hybrid drive mode completely coincides with a mechanical gear shifting point gain of the first stepless speed regulation hybrid drive mode, and the gear shifting point is just a mechanical gear shifting working point for realizing mutual smooth switching of the first stepless speed regulation hybrid drive mode and the second stepless speed regulation hybrid drive mode. When the second power source 7 is used as a speed-regulating power-splitting motor, the first power source 6 can be used as a driving motor and linked in parallel with the third power source 5, the third power source 5 can be used as a main driving power, and if the power split of the second power source 7 is negative power, namely power-splitting power generation, the control mode is used as a main high-efficiency driving control mode of a second stepless speed-regulating hybrid driving mode. The second stepless speed regulation hybrid driving mode is suitable for the power requirement of the vehicle from low load to medium load from low speed to high speed.

Second engine direct drive mode (FG2 mode): the second engine direct drive mode (parallel hybrid with second gear fixed speed ratio) is that the second power source 7 is regulated to zero speed on the basis of the second stepless speed regulation hybrid drive mode, the power output by the third power source 5 can be transmitted to the second gear ring 41 through the first planetary gear mechanism 3 and the second planetary gear mechanism 4, then transmitted to the third gear 77 from the second gear ring 41, and output to the wheels through the third gear 77, and the third power source 5 can independently directly drive or carry out parallel hybrid with the non-speed regulation shunt motor.
