Abstract
A hybrid vehicle control device includes an engine, a motor/generator, an automatic transmission in which the gear ratio can be fixed by the driver's intention; and a drive wheel. The control device has an assist traveling mode and an engine generation traveling mode as hybrid modes in which the engine and the motor/generator are drive sources. The control device includes a rotational speed limit setting unit which sets a value that exceeds the upper rotational speed limit, at which the motor/generator can carry out a torque output, as the rotational speed limit of the engine motor rotational speed, and a rotational speed limit control unit for reducing the rotational speed limit to the rotational speed limit at which the motor/generator can carry out a torque output, when the engine motor rotational speed has reached the rotational speed limit and there is a torque output request of the motor/generator.
