Abstract
Official abstract text for this publication.
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: a reverse drive control portion configured to operate the first electric motor so as to generate a positive torque and operate the second electric motor so as to generate a negative torque, with the clutch being placed in the engaged state, to run the hybrid vehicle in a reverse direction.
