Abstract
Official abstract text for this publication.
Provided is a hybrid vehicle driving device including: a first differential mechanism configured to be connected to an engine and transmit a rotation of the engine; a second differential mechanism configured to connect the first differential mechanism and a driving wheel; and a switching device configured to shift the first differential mechanism, wherein the second differential mechanism includes a first rotation component connected to an output component of the first differential mechanism, a second rotation component connected to the first rotation machine, and a third rotation component connected to the second rotation machine and the driving wheel, and a reaction torque of the first rotation machine is corrected at a torque phase (S 2 -Y) after a start of the gear shift operation of the first differential mechanism by the switching device while the vehicle travels by using the engine as a power source (S 3 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A hybrid vehicle driving device comprising: a first differential mechanism configured to be connected to an engine and transmit a rotation of the engine; a second differential mechanism configured to connect the first differential mechanism and a driving wheel; and a switching device configured to shift the first differential mechanism, wherein the second differential mechanism includes a first rotation component connected to an output component of the first differential mechanism, a second rotation component connected to a first rotation machine, and a third rotation component connected to a second rotation machine and the driving wheel, and a reaction torque of the first rotation machine is corrected at a torque phase after a start of the gear shift operation of the first differential mechanism by the switching device while the vehicle travels by using the engine as a power source. 2. The hybrid vehicle driving device according to claim 1 , wherein at the time the first differential mechanism is shifted by the switching device, an output torque of the engine is constant or a change rate of the output torque is smaller than a predetermined value. 3. The hybrid vehicle driving device according to claim 1 , wherein the reaction torque is corrected so as to suppress undershoot of the rotation speed of the first rotation machine at the torque phase. 4. The hybrid vehicle driving device according to claim 1 , wherein the gear shift operation is an up-shift operation, and the reaction torque is decreased by the correction of the reaction torque. 5. The hybrid vehicle driving device according to claim 1 , wherein the gear shift operation is a down-shift operation, and the reaction torque is increased by the correction of the reaction torque. 6. The hybrid vehicle driving device according to claim 1 , wherein the switching device includes a clutch device, the reaction torque of the first rotation machine is corrected at the torque phase based on an estimated torque of an engaging clutch of the clutch device, the estimated torque of the engaging clutch being an estimated torque of an engaging torque when the clutch device is engaged at the time the first differential mechanism is shifted.
