A control device of a hybrid drive unit, wherein an output member is connected to a first prime mover, and wherein a second prime mover capable of outputting at least one of a positive torque and a negative torque is connected through a transmission to said output member, comprising: a running restriction judger for judging that a running control of at least one of said first prime mover and said second prime mover is restricted, and a shift point changer for changing a shift point, in which a decision of a gear shift of said transmission is to be satisfied when the running restriction judger judges that the running control is restricted, different from the shift point of a case in which the running control is not restricted.
