A hybrid vehicle drive system includes: an engine; a rotary machine; a gear type engagement device configured to regulate rotation of the rotary machine; a first mode in which a reaction force of the engine is received by a torque of the rotary machine and a vehicle travels using the engine as a power source; and a second mode in which the reaction force of the engine is received by the engagement device and the vehicle travels using the engine as a power source. A first control of receiving the reaction force of the engine by the torque Tmg of the rotary machine, increasing the magnitude of the torque of the rotary machine to be equal to or greater than an upper limit of an estimated torque range Rte of the engine, and then decreasing the magnitude of the torque of the rotary machine is performed when the engagement device is disengaged from the second mode. The magnitude of a slope ²1 of the torque of the rotary machine when the magnitude of the torque of the rotary machine is decreased in the first control is equal to or less than the magnitude of a slope ± of a torque of the engine when the torque Te of the engine decreases due to explosion fluctuation of the engine.
