Control planning between each operating mode of 1 transmission device of table and shifting element
In electric-only mode, when being individually closed the first brake B1, using the first motor EM1 or the second motor EM2 or Person the first motor EM1 and the second motor EM2 drive simultaneously, and it is pure to be defined as the first i.e. fixed drive ratio of gear pure electric vehicle drive pattern Electric model EV-1.When the first motor EM1 and the second motor EM2 drive simultaneously, transmission device can export larger driving Torque, the pattern also serve as the large torque output mode of pure electric vehicle state.
It when being individually closed second brake B2, is driven using the second motor EM2, which is the second gear pure electric vehicle Drive pattern EV-2.The first motor EM1 is off position in this mode.
With the increase of speed, the first motor EM1, the rotating speed of the second motor EM2 were likely in above-mentioned each gear Height, the first brake B1 of control, second brake B2, first clutch C1 and second clutch C2 are in an open state, use First motor EM1 and the second motor EM2 drive simultaneously, which is third gear position pure electric vehicle drive pattern EV-3.When One motor EM1 and during equal the second motor EM2 rotating speeds, each planetary gear elements rotating speed is also equal, and vehicle can obtain highest at this time Speed is excessively high without causing the first motor EM1 and second motor EM2 itself rotating speed.
Under hybrid power drive pattern, first clutch C1 is closed, and transmission device is run with dynamic branch operating mode, It is defined as the first gear hybrid mode HEV-1.The pattern as the main hybrid power drive pattern of entire transmission device, It can realize vehicle variable speed E-CVT functions, this pattern is stepless shift mode, without fixed drive ratio.
The first brake B1 and second clutch C2 is controlled to be closed, engine can be realized same with the second motor EM2 at this time Axis is driven, and larger torque can be exported under the fixed drive ratio pattern, while the first motor EM1 can also participate in work, The pattern definition is the second gear hybrid power drive pattern HEV-2.The pattern is driven as the large torque under hybrid mode Dynamic model formula is used in vehicle start.
When vehicle speed is higher, the first motor EM1 can be operated near zero-turn speed, and the first motor EM1 efficiency is very at this time Difference, control second brake B2 is closed and first clutch C1 is closed, and the first motor EM1 lockings are conducive to improve the operating mode The transmission efficiency of underdrive device.The fixed drive ratio pattern definition is third gear position hybrid power drive pattern HEV-3.
The first brake B2 and second clutch C2 is controlled to be closed, engine can be realized same with the second motor EM2 at this time Rotating speed can export high torque under the fixed drive ratio pattern.The pattern definition drives for fourth speed position hybrid power Pattern HEV-4.
Second clutch C2 is controlled to be closed, engine can realize same rotating speed with the second motor EM2 at this time, be driven simultaneously Device is run with dynamic branch operating mode, is defined as fifth speed position hybrid power drive pattern HEV-5.The pattern can be realized The variable speed E-CVT functions of vehicle, this pattern is stepless shift mode, without fixed drive ratio.
Control first clutch C1 and second clutch C2 is closed, at this time engine ICE rotating speeds and the first motor EM1, Second motor EM2 and output rotating speed are equal, and each planetary gear elements rotating speed is also equal.Vehicle can obtain highest vehicle at this time Speed is excessively high without causing the first motor EM1 and second motor EM2 itself rotating speed, this pattern definition is sixth speed position hybrid power Drive pattern HEV-6.
Under parking charge mode, vehicle is in parked state, and control second clutch C2 is closed, at this time engine ICE bands Dynamic second motor EM2 power generations, charge to vehicle battery system.The pattern definition is parking charge mode -1.
Under parking charge mode, vehicle is in parked state, and when control first clutch C1 is closed, engine ICE passes through Planetary gear coupling mechanism 5 drives the first motor EM1 and the second motor EM2 to generate electricity simultaneously.The pattern definition charges for parking Pattern -2.
Under Brake energy recovery pattern, when vehicle occurs sliding and brake, control first clutch C1, second clutch C2, the first brake B1 and second brake B2 are opened, and engine ICE is disconnected more effectively to recycle braking energy. At this point, wheel reversely drives output shaft 6, output shaft 6 drives the first motor EM1 and second by planetary gear coupling mechanism 5 Motor EM2 generates electricity, and charges to vehicle battery system, to realize energy regenerating during vehicle braking.
Under reversing mode, the first brake B1 of control is closed, and when the second motor EM2 of control is reversely rotated, can realize vehicle Reversing mode.The first motor EM1 can also be controlled to reversely rotate at this time, to increase vehicle backing torque.
