It is an object of the present invention to prevent misjudgment of the engagement start of the friction engagement element when the drive source is rotationally fluctuated due to disturbance factors other than the engagement start of the friction engagement element. The hybrid vehicle control device is engaged by a drive source including at least the engine Eng and the motor / generator MG, a second brake B2 that is engaged when the D range is selected, and a rotation speed control of the motor / generator MG. Parameters that change as the engine Eng changes in rotation in the control means for maintaining the input rotation speed of the second brake B2 at the start of control (step S3 in FIG. 6) and the engagement control start area of the second brake B2. Is provided with an engagement start determination means for determining that the second brake B2 has started engagement when the value becomes equal to or greater than a predetermined threshold value. From the start of the engagement control of the second brake B2, the determination is started after waiting for a predetermined time when it can be determined that the rotational fluctuations of the engine Eng and the motor / generator MG have converged due to disturbance factors other than the start of the engagement of the second brake B2.
