CONTROL DEVICE FOR VEHICLE DRIVE DEVICE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To improve fuel consumption during driving by setting a differential part to be in a differential limit state in a control device for a vehicle drive device having a differential part and continuously variable transmission part connected to an engine, and capable of setting the differential part in a plurality of differential limit states. <P>SOLUTION: The control device for a vehicle drive device includes: an electric differential part 20 connected to the engine 10; a changeover brake B0 and a changeover clutch C0 for limiting (locking) a differential operation of the electric differential part 20; and a continuously variable transmission 30. In the control device, fuel consumption can be improved by selecting a driving state having a better transmission efficiency of the control device for a vehicle drive device after limiting the differential operation in a state capable of selecting between the differential limit state for locking the changeover brake B0 and the differential limit state for locking the changeover brake C0. <P>COPYRIGHT: (C)2010,JPO&INPIT |
