A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; and an engine, a first electric motor, a second electric motor 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 engine drive control portion configured to temporarily change an output torque of the engine when operating states of the clutch and the brake are changed in respective opposite directions to switch a vehicle drive mode from one of drive modes to another.
