In a hybrid vehicle control apparatus, a motor control unit executes the input power control on a MG unit independently from a torque control on an AC motor so that the input power control and the torque control are stabilized. The motor control unit further executes a torque difference reduction control, which controls current vector of the AC motor, to reduce a torque difference to zero substantially thereby preventing uncomfortable torque variation in a transient condition of input power control of the MG unit. The torque difference is calculated based on a first estimated torque calculated from a detected motor torque of the AC motor and a second estimated torque calculated from a command current vector for torque control of the AC motor.
