A control device controlling a hybrid vehicle provided with a planetary gear mechanism including a first gear connected to a first rotary electric machine, a carrier connected to an engine shaft of an internal combustion engine, and a second gear connected to a drive shaft to which a second rotary electric machine is connected and a rotation blocking mechanism 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 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 output by the first rotary electric machine and a second torque output by the second rotary electric machine in a state where the internal combustion engine is stopped.
