PROBLEM TO BE SOLVED: To provide a hybrid vehicle control device that can suppress frequent occurrence of switching of modes of a power transmission mechanism more than before.SOLUTION: A control device 30, which is applied to a hybrid vehicle 1 that comprises an internal combustion engine 10 and a second MG 12 as power sources and can switch a speed change mode of a power dividing mechanism 14, which can change and transmit rotation speed of the internal combustion engine 10 to an output portion 15 for transmitting torque to a driving wheel 3, to a continuously variable transmission ratio mode and a fixed gear ratio mode, determines whether or not the switching of the speed change mode is prohibited on the basis of vehicle speed and inclination of a road surface and when determining that the switching is prohibited, maintains the speed change mode in the continuously variable transmission ratio mode or the fixed gear ratio mode. |
