<P>PROBLEM TO BE SOLVED: To provide a control device of a hybrid vehicle capable of reaching a speed ratio (gear ratio) and a drive torque to target values with a good response according to a drive torque change instruction and providing the effect of an improvement in fuel economy. <P>SOLUTION: In this hybrid vehicle, a plurality of motor generators MG1 and MG2 used as a main torque source and an auxiliary torque source are connected to a floating gear transmission mechanism with two degrees of freedom, and the speed ratio (gear ratio) of the main torque source and a load is determined by the motor speeds N1 and N2 of the plurality of motor generators MG1 and MG2. The hybrid vehicle comprises a first associated control means performing a transmission control for first varying the speed ratio (gear ratio) of the main torque source and the load against a drive torque variation instruction and varying an output drive torque later when the torque response of the main torque source is delayed relative to the torque response of the auxiliary torque source. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
