A drive control device for a hybrid vehicle is provided with a differential device including four rotary elements; an engine, first and second electric motors and an output rotary member which are respectively connected to the four rotary elements; and a parking lock mechanism having a parking lock pole preventing rotation of a parking lock gear connected to the output rotary member when a manually operated shifting device selects a parking range. 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 sets a drive mode to an engine drive mode in which the brake is placed in a released state while the clutch is placed in an engaged state when a shift change is made into the parking range to achieve a parking lock with the parking lock mechanism. |
