Abstract: PROBLEM TO BE SOLVED: To provide a control device of a vehicle drive device that can satisfy both observance of the power restriction of a power storage device and maintenance of the power performance.SOLUTION: Since a first electric motor MG1 is in a upstream side more than a torque converter, time lag by fluid is caused to the transmission of the torque change caused by the change to the turbine wheel, even if a first electric motor power is changed when the power balance exceeds the battery restriction. Even if a second electric motor power is not changed during this torque transmission delay, the drive torque (driving force also agrees) is not influence. In a word, excess of battery restriction of power balance can be suppressed to a high degree of accuracy only by change of the first electric motor power while maintaining a present drive torque.
