A control device (11) controlling a hybrid vehicle (1) provided with a planetary gear mechanism (22) including a first gear (23S) connected to a first rotary electric machine (MG1), a carrier (23C) connected to an engine shaft (26) of an internal combustion engine (21), and a second gear (23R) connected to a drive shaft (43) to which a second rotary electric machine (MG2) is connected and a rotation blocking mechanism (24) blocking the rotation of the engine shaft in the other direction adjusts the ratio of a first torque to a total torque based on the result of the determination of whether or not the temperature (tl) of a first gear mechanism satisfies a desired condition in a case where the hybrid vehicle travels in a dual drive traveling mode in which the hybrid vehicle travels by using both the first torque (Tg) output by the first rotary electric machine and a second torque (Tm) output by the second rotary electric machine in a state where the internal combustion engine is stopped.
