Vibration damping control apparatus

A vibration damping control apparatus mounted on a hybrid vehicle comprising an engine and a motor generator coupled with the engine, said vibration damping control apparatus comprising:

• a pulsating torque calculating device configured to calculate pulsating torque of the engine;
• a first inertia torque calculating device configured to calculate first inertia toque which is inertia torque of the engine;
• a consumption torque calculating device configured to set, as consumption torque, a value obtained by subtracting the calculated first inertia torque from the calculated pulsating torque;
• a vibration damping torque calculating device configured to set, as shaft torque of an output shaft of the engine, a value obtained by subtracting the calculated consumption torque from base torque of the motor generator, and to calculate vibration damping torque which is torque for suppressing a variation in the shaft torque;
• and
• a controlling device configured to control the motor generator such that torque outputted from the motor generator is a sum of the base torque and the calculated vibration damping torque.
