Abstract
Official abstract text for this publication.
A driving device for a hybrid vehicle includes a transmission unit configured to output a rotation of an engine while changing rotating speed of the engine; and a first rotating electric machine. The first rotating electric machine is configured to supply a torque for increasing the rotating speed of the engine at the time of starting up of the engine to the engine through the transmission unit. At the time of starting up of the engine, the gear shift stage of the transmission unit is switched to an overdrive state. Thus, a torque sufficient for starting up of the engine can be supplied to the engine, and hence the engine can be appropriately started up.
First claim
Opening claim text (preview).
The invention claimed is: 1. A driving device for a hybrid vehicle, comprising: a transmission unit configured to output a rotation of an engine while changing a rotating speed of the engine; and a rotating electric machine, wherein the rotating electric machine is configured to supply a torque to the engine through the transmission unit for increasing the rotating speed of the engine at the time of starting up of the engine, in a high load state of the rotating electric machine, the engine is started up with the transmission unit in an overdrive state, and in a state other than the high load state, a gear shift stage of the transmission unit is selected in accordance with a travel condition of the hybrid vehicle and then the engine is started, and the high load state of the rotating electric machine is a state where a high damping torque is needed while the hybrid vehicle travels by using the rotating electric machine, or a state where a high damping torque is needed after the starting up of the engine. 2. The driving device for a hybrid vehicle according to claim 1 , wherein the rotating electric machine is a first rotating electric machine, the driving device further includes a differential unit configured to connect the transmission unit to drive wheels, and a second rotating electric machine, an output shaft of the engine is connected to an input component of the transmission unit, and the differential unit includes a first rotation component connected to an output component of the transmission unit, a second rotation component connected to the first rotating electric machine, and a third rotation component connected to the second rotating electric machine and the drive wheels. 3. The driving device for a hybrid vehicle according to claim 2 , wherein a high speed gear shift stage is in the overdrive state. 4. The driving device for a hybrid vehicle according to claim 3 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to the high speed gear shift stage and the engine is started up. 5. The driving device for a hybrid vehicle according to claim 2 , wherein the high load state of the first rotating electric machine is while the vehicle travels by using the first rotating electric machine. 6. The driving device for a hybrid vehicle according to claim 2 , wherein the high load state of the first rotating electric machine is after the starting up of the engine. 7. The driving device for a hybrid vehicle according to claim 2 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to a high speed gear shift stage and the engine is started up. 8. The driving device for a hybrid vehicle according to claim 1 , wherein a high speed gear shift stage is in the overdrive state. 9. The driving device for a hybrid vehicle according to claim 8 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to the high speed gear shift stage and the engine is started up. 10. The driving device for a hybrid vehicle according to claim 1 , wherein the high load state of the rotating electric machine is while the vehicle travels by using the rotating electric machine. 11. The driving device for a hybrid vehicle according to claim 10 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to a high speed gear shift stage and the engine is started up. 12. The driving device for a hybrid vehicle according to claim 1 , wherein the high load state of the rotating electric machine is after the starting up of the engine. 13. The driving device for a hybrid vehicle according to claim 12 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to a high speed gear shift stage and the engine is started up. 14. The driving device for a hybrid vehicle according to claim 1 , wherein the transmission unit is switched to a predetermined gear shift stage which is used while the vehicle travels by using the engine after the transmission unit is switched to a high speed gear shift stage and the engine is started up.
