When motor 7 is in idle state, gearbox 6 is placed in the position of neutral gear, planet row will not reversely drive main drive motor 7
Rotated, reduce the load of system output, improve the whole work efficiency of system.
Hybrid power system in the utility model can have pure electric drive, combination drive, engine direct drive, Brake Energy
The mode of operations such as amount recovery, it is described in detail below：
1st, pure electric drive mode：
Hybrid power system in the pattern, engine do not start, and ISG motors do not work, and lockable mechanism unclamps, main drive
Dynamic motor driving, power by main drive motor rotor be transferred to gearbox through gearbox slow down increase turn round after passed by reduction gearing
Pass planet row gear ring, planet row gear ring driving vehicle traveling.Need gearbox selection different according to different speed and operating mode
Gear so that on the premise of vehicle working condition traveling demand is met, main drive motor all the time in high efficiency region work, from
And lifting system efficiency.
2nd, combination drive pattern：
Under this pattern, lockable mechanism unclamps, engine work, and adjusting engine according to vehicle demand ISG motors turns
Speed and moment of torsion cause engine to be run all the time in high efficiency region so as to lift fuel economy.Main drive motor is according to vehicle
The size of demand torque determines the need for power-assisted, when the moment of torsion of vehicle demand is larger, can not meet by engine merely
During vehicle torque demand, electric machine controller 8 controls main drive motor output torque driving vehicle.When engine output torque meets
During vehicle torque demand, gearbox is in the position of neutral gear, avoids main drive motor with the loss in efficiency for turning to bring.Work as engine
During in high efficient area, when the moment of torsion exported by planet row is more than vehicle demand, motor is in power generation mode, will be unnecessary
Mechanical energy be converted in power storage to electrokinetic cell 9.
3rd, engine direct drives pattern：
When speed is higher, engine is in high efficiency region work, and lockable mechanism locking ISG motors cause at engine
The engine direct drive vehicle under the pattern that direct drive planet row rotates, this pattern, main drive motor is according to vehicle demand
The size of moment of torsion determines whether power-assisted.This pattern eliminates the operating mode of ISG electric power generations compared to combination drive pattern, eliminates energy
The conversion of amount, improves energy utilization efficiency.
4th, Brake energy recovery pattern：
Engine does not work under this pattern, and ISG motors do not work, and main drive motor provides brake force, according to different systems
Power demand, gearbox are in different gears, ensure that main drive motor can provide the braking torque of abundance, now, vehicle
Reversely main drive motor is driven to rotate, main drive motor is in power generation mode, unnecessary mechanical energy is converted into power storage extremely
In electrokinetic cell 9.Because main drive motor is connected on the gear ring of planet row, and the system output shaft of planet row is also to be connected to
On the gear ring of planet row, therefore, under Brake energy recovery pattern, energy regenerating is completed by main drive motor.
Pass through engine, ISG motors, main drive motor, gearbox, the locking of lockable mechanism and release in the utility model
The work of multiple patterns is completed, to adapt to the demand of vehicle difference operating mode and speed.Carried in the utility model by gearbox
The high moment of torsion of main drive motor output, makes vehicle under electric model also being capable of normally travel.Meanwhile when engine works,
The transmission that main drive motor passes through gearbox also can be that engine carries out power-assisted.When vehicle at the uniform velocity small-power travels, will become
Fast case is placed in the position of neutral gear, it is therefore prevented that although main drive motor does not need power-assisted to be also required to transferring to lead in the prior art
The situation of loss in efficiency is caused to occur.
In the present embodiment, ISG motors are the first motor, and ISG only as regulation engine speed and moment of torsion and starts hair
The effect of motivation, it is used alone not as single driving power source, the second motor is main drive motor, in other embodiment
In, the first motor, the second motor can be the motor of driving vehicle traveling that can be independent.It is corresponding, can be two
Be respectively provided with gearbox between individual motor and planet row, can also only wherein one gearbox is set between planet row.
