An assist request or a power generation request can be met while reflecting the high-load travel request of the driver. A control device for a hybrid vehicle comprises, in the drive system: an engine (Eng); a motor/generator (MG); an automatic transmission (AT) in which the gear ratio can be fixed by the driver's intention; and drive wheels (RL, RR). The control device comprises an assist traveling mode and an engine generation traveling mode as hybrid modes in which the engine (Eng) and the motor/generator (MG) are drive sources. The control device is provided with: a rotational speed limit setting unit (411) which sets a value that exceeds the upper rotational speed limit, at which the motor/generator (MG) can carry out a torque output, as the rotational speed limit (La) of the engine-motor rotational speed (Nem), and a rotational speed limit control unit (413) for reducing the rotational speed limit (La) to the rotational speed limit (Lb) at which the motor/generator (MG) can carry out a torque output, when the engine-motor rotational speed (Nem) has reached the rotational speed limit (La) and there is a torque output request of the motor/generator (MG). |
