Abstract
A drive control device for a hybrid vehicle is provided with a differential device having four rotary elements. One of the four rotary elements is constituted by rotary components of each of a first and a second differential mechanisms selectively connected to each other through a clutch. One of the rotary components of said first and second differential mechanisms selectively connected through said clutch is selectively fixed to a stationary member through a brake. The drive control device comprises a brake engagement control portion configured to place the brake in an engaged state upon starting an engine, and an electric motor operation control portion configured to operate a first electric motor to raise a speed of a rotary motion of the engine for starting of the engine and to operate a second electric motor to reduce a reaction force during starting of said engine acting on an output rotary member.
