In the present embodiment, the first lock-up clutch 12 of power between cut-out planet row and gearbox 5 is equipped at gear ring 4,
First lock-up clutch 12 constitutes planet row output end lock-up clutch；When needing engine 1 to start or stop, the first lock
Only clutch 12 coordinates with gearbox 5, and gearbox is in neutral gear, while being protected 4 locking of gear ring by the first lock-up clutch 12
Card positive dragging torque and reversely dragging torque energy that when engine 1 starts or stops, stand-by motor 11 applies engine 1
It is enough transmitted on engine 1.
In the present embodiment, main drive motor 6 is MG1, and stand-by motor 11 is MG2.
In terms of vehicle control：
Pattern switching logic：Gearbox 5 gives tacit consent to gear in neutral gear, and 1）When speed is more than v1, gearbox 5 is cut by neutral gear
One grade, by EV patterns of connecting（Transmission neutral）To EVT Mode（One grade of gearbox）Switching；When speed is less than v8, EVT Mode
（Engine 1 and main drive motor 6 participate in jointly）Switch back into EV patterns；2）When speed is more than v2, gearbox 5 is changed to by one grade
Two grades；When speed is less than v7,5 gear of gearbox retracts one grade by two grades；3）When speed is more than v3, the first lock-up clutch
3 lockings, vehicle enter the straight drive pattern of 1 one grades of engine, and when speed is less than v6, the separation of the first lock-up clutch 3 is exited and started
1 one grades of machine is straight to drive pattern；（4）When speed is more than v4, vehicle enters engine 1 and is changed to two grades of straight drive moulds by one grade of straight drive pattern
Formula, when speed is less than v5, gearbox 5 drives pattern by two grades of one grade of switchbacks are straight, and vehicle enters the straight drive pattern of 1 one grades of engine.
Wherein speed v8<v1<v7<v2<v6<v3<v5<v4.
When driving：Pattern switching sequence is respectively transmission neutral series connection EV patterns, one grade of EVT gearboxes, EVT gearboxes
Two grades, engine direct drive one grade of gearbox, engine direct drive five kinds of operating modes of gear box second gear.1）Gearbox 5 cuts neutral gear, hair
Motivation 1 is shut down, and stand-by motor 11 does not work, and planet row is in the state that shuts down, and drives vehicle by main drive motor 6, at this time
The lower EV pattern startings of vehicle series connection；2）It is changed to one grade by neutral gear when speed reaches v1 rear transmission gear boxs 5, is switched to by EV series models
EVT Mode, engine 1 begin participating in driving, and the output torque of main drive motor 6 starts to reduce and engine 1 drives together；
3）Two grades, after vehicle is switched to two grades are changed to by one grade when speed reaches certain value v2 rear transmission gear boxs 5,5 two grades of gearbox works,
The output torque of main drive motor 6 further decreases, and continues and engine 1 together power-assisted；4）After speed reaches v3, to keep away
Exempt from the energy loss of power cycle generation, 3 locking sun gear 9 of the second lock-up clutch, stand-by motor 11 shuts down, main driving
Motor 6 does not work and with turn, gearbox 5 cuts one grade of work, and vehicle enters the straight drive pattern of one grade of engine；5）When speed reaches
After v4, to promote the efficiency of engine working point, vehicle enters the straight drive pattern of two grades of engine.
When engine 1 starts or shuts down：After meeting the startup of engine 1 or halt condition, first controls gearbox 5 and cut sky
Gear, while 12 locking gear ring 4 of the first lock-up clutch, if judging that current gear has been in neutral gear, and the first lock-up clutch
12 are in lockup state, then control module is sent to stand-by motor 11 starts or shut down control dragging torque, and is sent out to engine 1
It send startup or shuts down control flag bit.After the completion of engine 1 starts or shuts down, control gearbox 5 restores current demand gear.
In other embodiments, the planet carrier of the stand-by motor and planet row is sequentially connected；In other embodiments, become
Fast case can be the gearbox of three gears or more；In other embodiments, torque can be not provided on the output shaft of engine to subtract
Shake device, in other embodiments, clutch can be not provided between sun gear and stand-by motor.
