Abstract
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 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 releases one of the clutch and the brake when the engine is started in a drive mode in which the engine is at rest while the clutch and the brake are in an engaged state, selecting the one of the clutch and the brake to be released, depending upon a drive force generated during starting the engine.
