PROBLEM TO BE SOLVED: To provide a drive control device of a hybrid vehicle which efficiently recovers kinetic energy of the vehicle during deceleration traveling as compared with a conventional device.SOLUTION: By releasing a clutch CL and a brake BK by a drive force increase control part 80 during deceleration traveling when regeneration by a first electric motor MG1 and/or a second electric motor MG2 can not carried out, kinetic energy of a vehicle is stored as rotation energy in the second electric motor MG2, and the rotation energy is utilized as drive force of the vehicle. Therefore, when the kinetic energy of the vehicle, which rotates a rotor 24 of the second electric motor MG2 during the deceleration traveling, releases the clutch CL and the brake BK, the rotor 24 of the second electric motor MG2 is freely rotated and the rotation energy of the second electric motor MG2 is stored. Therefore, the kinetic energy of the vehicle when regeneration by the first electric motor MG1 and/or the second electric motor MG2 can not carried out is efficiently recovered and is utilized as the drive force of the vehicle, and fuel economy is improved.
