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 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 hybrid vehicle is selectively placed in a plurality of drive modes according to respective combinations of engaged and released states of the clutch and the brake. The drive control device comprises: a substitutive drive control portion configured to alternately implement a vehicle driving control and a battery charging control in the event of a failure of one of the first and second electric motors, the vehicle driving control being implemented to operate the other of the first and second electric motors, for generating a vehicle drive force, and the battery charging control being implemented to charge a vehicle driving battery with the other electric motor.
