PROBLEM TO BE SOLVED: To provide a control device for a hybrid vehicle capable of stabilizing rotational speed of an engine.SOLUTION: The control device 1 for a hybrid vehicle includes: an engine 2; planetary gear mechanisms 3, 4 connected to the engine 2; two electric motors 5, 6 connected to the planetary gear mechanisms 3, 4 respectively; and an output shaft 7 connected to the engine 2 and the electric motors 5, 6 through the planetary gear mechanisms 3, 4. The control device for a hybrid vehicle controls the electric motors 5, 6 so that rotational speed of the engine 2 converges into target rotational speed. The control device for a hybrid vehicle further includes correction means for, when it is detected that the differential rotation speed of the planetary gear mechanisms 3, 4 is within the range set near 0, reducing a correction value of feedback control of the electric motors 5, 6, to be executed to converge the rotational speed of the engine 2 into the target rotational speed. |
