Operation principle and mode division：

Refering to Fig. 1, Fig. 2, a kind of described planetary parallel-serial hybrid power system dynamic using one-way clutch inputs There are three parts：Engine, motor/generator MG1, motor/generator MG2.The power of engine is defeated by front-seat planet carrier power Enter axle 1 to input, motor/generator MG1 power is inputted by front-seat sun gear 8, motor/generator MG2 power by heel row too The input of sun wheel 25.

1. electric-only mode

Electric-only mode is mainly used in starting vehicle and low cruise, can be divided into two motors according to the different state of two motors It is operated alone and combines drive pattern with two motors, its common trait is that brake B, clutch C are in released state.

Motor/generator MG2 electric-only modes：

Under this pattern, only motor/generator MG2 work.Because engine does not work with motor/generator MG1, F2 One-way clutch inside race rotating speed is 0, and outer race rotating speed is identical with heel row sun wheel speed, and F2 one-way clutch is automatically separated. Power transmission route is：Electrokinetic cell is powered, and is converted into mechanical energy by motor/generator MG2 and is input to heel row sun gear, then passes through Heel row planet carrier passes to power output shaft 37, and wheel is output to after the deceleration of main reducing gear increases torsion effect.

Motor/generator MG1 electric-only modes：

When motor/generator MG2 breaks down, motor/generator MG1 may participate in pure electronic.It is only electric under this pattern Machine/generator MG1 work.Engine is locked out under the effect of F1 one-way clutch, and F2 one-way clutch outer races rotating speed is 0, Inside race is identical with the rotating speed of intermediate propeller shaft 16, and F2 one-way clutch engages automatically.Power transmission line is：Electrokinetic cell supplies Electricity, mechanical energy is converted into by motor/generator MG1 and is input to front-seat sun gear, premenstrual planet row passes to jackshaft 16, then passes through F2 one-way clutch and rear planet row pass to power output shaft 37, are finally output to after the deceleration of main reducing gear increases torsion effect Wheel.

Two motors combine electric-only mode：

Under this pattern, two motors work simultaneously.Engine is locked out under the effect of F1 one-way clutch, F2 one-way clutch Outer race rotating speed is identical with motor/generator MG2 rotating speeds, and inside race is identical with the rotating speed of intermediate propeller shaft 16, can adjust motor/hair Motor MG1 rotating speeds cause F2 one-way clutch inside races rotating speed to be more than outer race rotating speed, and now one-way clutch engages automatically.It is dynamic Power transfer route is：Electrokinetic cell is powered, and is converted into by motor/generator MG1 after mechanical energy and is input to front-seat sun gear, before menstruation Planet row passes to jackshaft 16, then through F2 one-way clutch by power coupling after at planet row sun gear, with motor/generator Planet row passes to power output shaft 37 after after MG2 power superposition, finally defeated after the deceleration of main reducing gear increases torsion effect Go out to wheel.

2. paralleling model

When speed is higher, brake B engagements, preceding planet row sun gear 13 is locked, and whole preceding planet row is equivalent to one Individual fixed speed ratio, the power that now engine 79 exports all are output to wheel by mechanical path, have higher transmission efficiency.

3. electronics electrodeless variable-speed pattern

Engagement and released state of the electronics electrodeless variable-speed pattern according to F2 one-way clutch and clutch C, can be divided into low speed Pattern and fast mode.The common trait of both subpatterns is：Now engine, motor/generator MG1, motor/generator MG2 is in working condition, and F1 one-way clutch is automatically separated, and brake B separation, an engine output part is passed through Preceding planet row is output to wheel by mechanical path, and another part is converted into electrical power by motor/generator MG1.

Low-speed mode：

Refering to Fig. 6, in the low-speed mode, clutch C is in released state, and seniority among brothers and sisters carrier is defeated in the past for the power of engine Enter, motor/generator MG1 is connected with front-seat sun gear, plays a part of adjusting engine working point, F2 one-way clutch inner seats It is identical with the rotating speed of intermediate propeller shaft 16 to enclose rotating speed；Now acted on by motor/generator MG1 rotational speed regulation, toothrow before control Enclose rotating speed rise, when occur F2 one-way clutch inside races rotating speed exceed outer race rotating speed trend when, one-way clutch is automatic Engagement, the power of preceding planet row transmission couple at rear planet row sun gear；Planet row gear ring locking afterwards, power is via planet carrier Power output shaft 37 is passed to by high-speed clutch piston cylinder 32 to export；Motor/generator MG2 is coupling in the sun gear of heel row Place, there is provided power-assisted.

Fast mode：

Refering to Fig. 7, when vehicle control system requires that vehicle operational mode switches to fast mode by low speed, clutch C Start is in engagement state, and now intermediate propeller shaft 16 is identical with the rotating speed of power output shaft 37, i.e. F2 one-way clutch inside race Rotating speed is identical with heel row planet carrier rotating speed, and outer race rotating speed is still identical with heel row sun wheel speed, in interior outer race rotating speed In the presence of difference, F2 one-way clutch is automatically separated；Motor/generator MG2 is coupling at the sun gear of heel row, there is provided power-assisted； The power of engine inputs from the planet carrier at front row, and motor/generator MG1 is connected with front-seat sun gear, and power is by front-seat tooth Circle output, and directly exported after intermediate propeller shaft 16 is delivered to and coupled at power output shaft 37.

Vehicle electronic infinite variable speed at a high speed with low-speed mode handoff procedure, only need to be to clutch C activating pressure It is controlled, F2 one-way clutch is that the automatic function of engaging with separating, such pattern can be achieved by its structure latching characteristics Double clutch pressure SECO during switching is simplified.

4. braking mode

When automobile is under non-emergent brake condition, and speed is higher than a certain limit value, into braking mode.If When demand braking moment now is less than the maximum braking torque that motor/generator MG2 can be provided, brake force is all by electricity Machine/generator MG2 is provided, and the mechanical energy reclaimed changes into electrical power storage in the battery；If demand braking moment now is big A part in the maximum braking torque that motor/generator MG2 can be provided, brake force is provided by motor/generator MG2, The mechanical energy reclaimed changes into electrical power storage in the battery, and another part in brake force is carried by traditional mechanical braking For.
