In addition, power control unit ECU regulates hydraulic pressure by the actuator (omitting diagram) of solenoidoperated cluthes control loop 10, thus switches transmit mode and the off state of two clutches C1, C2.
Next, the work of the automatic transmission 1 formed as described above is described.Further, in the automatic transmission 1 of the 1st mode of execution, by making the 1st clutch C1 engage, the driving force of motor MG can be adopted and motor ENG is started.
First, when adopting the driving force of motor ENG to establish 1 fast shelves, making locking framework B1 be stationary state thus the gear ring Ra of planetary gears PG is fixed on case of transmission 7, making the 1st clutch C1 lock and become transmit mode.
The driving force of motor ENG is imported into the sun gear Sa of planetary gears PG via input shaft 2, the 1st clutch C1, the 1st gear shaft 4, it is 1/ (g+1) that the rotating speed being input to the motor ENG of input shaft 2 is decelerated, thus is passed to 3 speed drive gear G3a via planet carrier Ca.
The velocity ratio (number of teeth of the number of teeth/the 1st driven gear Go1 of 3 speed drive gear G3a) of the 3 fast train of gearings G3 be made up of 3 speed drive gear G3a and the 1st driven gear Go1 is set to i, the driving force being passed to 3 speed drive gear G3a is 1/i (g+1) by speed change, and export from output gear 3a via the 1st driven gear Go1 and output shaft 3, thus establish 1 fast shelves.
Like this, in the automatic transmission 1 of present embodiment, 1 fast shelves are established due to planetary gears PG and 3 fast train of gearings can be utilized, therefore without the need to engaging mechanism that 1 fast shelves are special, in addition, because planetary gears PG is configured in the motor MG of hollow, therefore, it is possible to shorten the axial length of automatic transmission further.
And, at 1 fast shelves, when vehicle be in deceleration regime and the charge rate SOC of storage battery BATT (State Of Charge) not enough predetermined value time, power control unit ECU carries out deceleration regeneration running, in described deceleration regeneration running, utilize motor MG to implement braking and generate electricity.In addition, when the charge rate SOC of storage battery BATT is more than predetermined value, motor MG can be made to drive, EV (Electric Vehicle: the electric vehicle) traveling travelling with the HEV (Hybrid Electric Vehicle: motor vehicle driven by mixed power) carrying out the driving force of auxiliary engine ENG or only utilize the driving force of motor MG to travel.
In addition, when be in travelling at EV allow the state of vehicle deceleration and the speed of a motor vehicle more than certain speed time, by making the 1st clutch C1 lock gradually, can adopt the kinetic energy of vehicle that motor ENG is started, and not adopt the driving force of motor MG.
In addition, with 1 speed grade running process in, when power control unit ECU according to the vehicle information predictions such as the aperture of the speed of a motor vehicle or gas pedal to shift up be 2 fast shelves, the 2 fast side connecting states the 2nd engaging mechanism SM2 being become 2 speed drive gear G2a and the 2nd gear shaft 5 are linked or the pre-gearshift close to this state.
When adopting the driving force of motor ENG to establish 2 fast shelves, the 2 fast side connecting states 2nd engaging mechanism SM2 being become 2 speed drive gear G2a and the 2nd gear shaft 5 are linked, the 1st clutch C1 is made to become off state, and, the 2nd clutch C2 is locked and becomes transmit mode.Thus, the driving force of motor ENG exports from output gear 3a via the 2nd clutch C2, idle pulley system Gi, the 2nd fast train of gearings G2 of gear shaft 5,2 and output shaft 3.
Further, at 2 fast shelves, when power control unit ECU predict to shift up, the 3 fast side connecting states the 1st engaging mechanism SM1 being become 3 speed drive gear G3a and the 1st gear shaft 4 are linked or the pre-gearshift close to this state.
On the contrary, when power control unit ECU predict want downshift, make the 1st engaging mechanism SM1 become to be off the neutral state of the link of 3 speed drive gear G3a and 5 speed drive gear G5a and the 1st gear shaft 4.
Thus, become transmit mode by means of only making the 1st clutch C1 and make the 2nd clutch C2 become off state and just can carry out shifting up or downshift, thus the switching of gear can be carried out when not drives interrupts power swimmingly.
In addition, at 2 fast shelves, when vehicle be in deceleration regime and the charge rate SOC of storage battery BATT not enough predetermined value time, power control unit ECU also carries out deceleration regeneration running.When 2 fast shelves carry out deceleration regeneration running, the 1st engaging mechanism SM1 is in 3 fast side connecting state or neutral states, and situation is different.
When the 1st engaging mechanism SM1 is in 3 fast side connecting state, 3 speed drive gear G3a rotate by means of the 1 fast driven gear Go1 rotated because of 2 speed drive gear G2a, 3 speed drive gear G3a make the rotor MGb of motor MG rotate via the 1st gear shaft 4, therefore, by suppressing the rotation of this rotor MGb to implement braking, thus generating is to regenerate.
When the 1st engaging mechanism SM1 is in neutral state, becoming stationary state by making locking framework B1 makes the rotating speed of gear ring Ra for " 0 ", utilize and the motor MG that sun gear Sa links makes to generate electricity with the rotating speed being engaged in the planet carrier Ca rotated together with the 3 speed drive gear G3a of 1 fast driven gear Go1, enforcement braking regenerates thus.
In addition, when 2 fast shelves carry out HEV traveling, such as, the 3 fast side connecting states 1st engaging mechanism SM1 being become 3 speed drive gear G3a and the 1st gear shaft 4 are linked, and the lock state making planetary gears PG become each component can not relatively to rotate, the driving force of motor MG is passed to output gear 3a via 3 fast train of gearings G3, can HEV traveling be carried out thus.Or, the 1st engaging mechanism SM1 is made to become neutral state, make locking framework B1 become reversion blocked state to make the rotating speed of gear ring Ra for " 0 ", with the path of 1 fast shelves, the driving force of motor MG is passed to the 1st driven gear Go1, the HEV that also can carry out 2 fast shelves thus travels.
When adopting the driving force of motor ENG to establish 3 fast shelves, the 3 fast side connecting states 1st engaging mechanism SM1 being become 3 speed drive gear G3a and the 1st gear shaft 4 are linked, the 2nd clutch C2 is made to become off state, and, make the 1st clutch C1 lock and become transmit mode.Thus, the driving force of motor ENG is passed to output gear 3a via input shaft 2, the 1st clutch C1, the 1st gear shaft 4, the 1st engaging mechanism SM1,3 fast train of gearings G3, and exports with the rotating speed of 1/i.
At 3 fast shelves, because the 1st engaging mechanism SM1 becomes the 3 fast side connecting states making 3 speed drive gear G3a and the 1st gear shaft 4 link, therefore, sun gear Sa and the planet carrier Ca of planetary gears PG become same rotation.
Therefore, the lock state that each component becoming planetary gears PG can not rotate relatively, if utilize motor MG to implement braking to sun gear Sa, then becomes the situation of deceleration regeneration, if utilize motor MG to make sun gear Sa transmission of drive force, then HEV traveling can be carried out.In addition, the 1st clutch C1 is disconnected, thus the EV that can also only utilize the driving force of motor MG to travel travel.
At 3 fast shelves, when power control unit ECU according to vehicle information predictions such as the apertures of the speed of a motor vehicle or gas pedal to when wanting downshift, the 2 fast side connecting states 2nd engaging mechanism SM2 being become 2 speed drive gear G2a and the 2nd gear shaft 5 are linked or the pre-gearshift close to this state, when predict to shift up time, the 4 fast side connecting states the 2nd engaging mechanism SM2 being become 4 speed drive gear G4a and the 2nd gear shaft 5 are linked or the pre-gearshift close to this state.
Thus, become transmit mode by means of only making the 2nd clutch C2 lock, and make the 1st clutch C1 disconnect and be off state, just can carry out the switching of gear, thus speed change can be carried out swimmingly when not drives interrupts power.
When adopting the driving force of motor ENG to establish 4 fast shelves, the 4 fast side connecting states 2nd engaging mechanism SM2 being become 4 speed drive gear G4a and the 2nd gear shaft 5 are linked, the 1st clutch C1 is made to become off state, and, make the 2nd clutch C2 lock and become transmit mode.
With 4 speed grade running process in, when power control unit ECU according to information of vehicles predict want downshift, the 3 fast side connecting states the 1st engaging mechanism SM1 being become 3 speed drive gear G3a and the 1st gear shaft 4 are linked or the pre-gearshift close to this state.
On the contrary, when power control unit ECU according to information of vehicles predict to shift up, the 5 fast side connecting states the 1st engaging mechanism SM1 being become 5 speed drive gear G5a and the 1st gear shaft 4 are linked or the pre-gearshift close to this state.Thus, be transmit mode by means of only making the 1st clutch C1 lock, and the 2nd clutch C2 disconnected form the state of being off, just can carry out downshift or shift-up, thus speed change can be carried out swimmingly when not drives interrupts power.
