A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; and an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements. One of the four rotary elements is constituted by a rotary component of a first differential mechanism and a rotary component of a second differential mechanism selectively connected through a clutch, and one of the rotary components is selectively fixed to a stationary member through a brake. The drive control device comprises an electric motor operation control portion configured to control the first and second electric motors to generate reaction torques in a drive mode of the hybrid vehicle in which the engine is operated in an engaged state of the clutch and in a released state of the brake; and a torque assignment ratio control portion configured to control a ratio of the reaction torques to be generated by the first and second electric motors, without a change of a drive force for driving the hybrid vehicle.
