Control apparatus for hybrid vehicle

A hybrid vehicle comprising:

• an engine which generates a torque for driving the hybrid vehicle;
• a transmission which is connected to an output shaft of the engine;
• driving wheels which are connected to an output shaft of the transmission;
• an electric motor which is connected to the driving wheels and assists the torque generated by the engine;
• a requested torque calculating device which calculates a torque requested for driving the hybrid vehicle;
• and
• a torque control device which controls a torque generated by an engine and a torque generated by an electric motor of the hybrid vehicle based on the requested torque calculated by the requested torque calculating device;
• wherein the torque control device controls the electric motor so as to generate a torque obtained by subtracting a torque to be generated by the engine from the requested torque, and
• wherein the torque control device comprises an engine torque restricting device which restricts the torque to be generated by the engine in accordance with a predetermined condition.

A control method for a hybrid vehicle, comprising:

• calculating a torque requested for driving the hybrid vehicle;
• controlling a torque generated by an engine and a torque generated by an electric motor of the hybrid vehicle based on the requested torque calculated by the requested torque calculating device;
• and
• controlling the electric motor so as to generate a torque obtained by subtracting a torque to be generated by the engine from the requested torque,
• wherein the torque generated by the engine is controlled to be restricted in accordance with a predetermined condition.
