This control device (11) controls a hybrid vehicle (1) which is provided with: a planetary gear mechanism (22) which includes a first gear (23S) coupled to a first rotation machine (MG1), a carrier (23C) coupled to the engine shaft (26) of an internal combustion engine (21), and a second gear (23R) coupled to a drive shaft (43) to which a second rotation machine (MG2) is coupled; and a rotation blocking mechanism (24) which blocks rotation of the engine shaft in the other direction. When, in a state in which the internal combustion engine has stopped and the hybrid vehicle is traveling in a dual drive travel mode using both a first torque (Tg) outputted by the first rotation machine and a second torque (Tm) outputted by the second rotation machine, the control device (11) adjusts the ratio of the first torque to the total torque on the basis of the determination result of whether or not the temperature (t1) of the first gear mechanism satisfies a desired condition.
