Abstract
A hybrid vehicle drive system includes: an engine; a rotary machine; a gear type engagement device; and a controller configured to: control a vehicle to travel in a first mode in which a reaction force of the engine is received by a torque of the rotary machine, and in a second mode in which the reaction force of the engine is received by the engagement device. The controller is configured to perform a first control of receiving the reaction force of the engine by the torque of the rotary machine, increasing a magnitude of the torque of the rotary machine to be equal to or greater than an upper limit of an estimated torque range of the engine, and then decreasing the magnitude of the torque of the rotary machine is performed at a time the engagement device is disengaged from the second mode.
