DEVICE FOR CONTROLLING HYBRID VEHICLE
First Claim
1. A hybrid vehicle control device for a hybrid vehicle, the hybrid vehicle control device comprising:
- an engine;
a motor/generator to which is connected a battery that carries out charging/discharging;
a transmission, in which a gear ratio can be fixed by a driver'"'"'s input;
a drive wheel; and
a controller programmed to selectively set an assist traveling mode in which the motor/generator outputs a drive torque, and an engine generation traveling mode in which the motor/generator outputs a power generation torque, as hybrid modes in which the engine and the motor/generator are drive sources,the controller being programmed to includea rotational speed limit setting unit programmed to set a value that exceeds an upper rotational speed limit, at which the motor/generator can carry out a torque output, as a rotational speed limit of an engine motor rotational speed, anda rotational speed limit control unit programmed to reduce the rotational speed limit to the upper rotational speed at which the motor/generator can carry out a torque output, when the engine motor rotational speed has reached the rotational speed limit, and a torque output request of the motor/generator exists, during the assist traveling mode in a state in which the gear ratio is fixed by the driver'"'"'s input.

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.
