Provided is a drive control device for a hybrid vehicle, the drive control device providing a sense of deceleration necessary and sufficient for the decelerating travel of the vehicle. A drive control device for a hybrid vehicle is provided with: a clutch (CL) for connecting and disconnecting the carrier (C 1) of a first planetary gear device (14) and the carrier (C2) of a second planetary gear device (16) to and from each other; and a brake (BK) for connecting and disconnecting the carrier (C2) to and from a housing (26). When the vehicle performs decelerating travel in a hybrid travel mode in which the engine (12) is driven, the clutch (CL) or the brake (BK) is engaged in a slipping manner. Consequently, the slip of the clutch (CL) or the brake (BK) can apply braking torque to an output shaft, and desired deceleration energy can be ensured.
