摘要：
A power transmission device of a hybrid vehicle includes: a transmission including a planetary mechanism including a plurality of transmission rotational elements, one of the transmission rotational elements being connected to a rotary shaft of an engine; a differential device including a plurality of differential rotational elements including one connected to one of the transmission rotational elements of the transmission, one connected to a rotary shaft of a first rotary machine, and one connected to a rotary shaft of a second rotary machine and a driven wheel; a transmission control device configured to control the transmission; and a control device configured to control the first rotary machine such that pinion differential rotation of the transmission or the differential device is set to be not higher than a predetermined value at a time unique motor EV driving is performed only by power of the second rotary machine.
