DRIVE DEVICE FOR HYBRID VEHICLE

摘要

This drive device for a hybrid vehicle comprises: an engine; a first rotary machine; a second rotary machine; a transmission unit that transmits the rotation of the engine; and a differential unit that includes a first rotary element connected to an output element of the transmission unit, a second rotary element connected to the first rotary machine, and a third rotary element connected to the second rotary machine and drive wheels. If the driver makes a gear-change request that requires a change in the rotation speed of the engine (S20-Y), then the changing of the rotation speed of the engine is restricted at the time of starting the gear change (S30). It is preferable that the changing of the rotation speed of the engine is completed before the completion of the inertia phase.
