Vibration damping control apparatus

摘要

A vibration damping control apparatus is mounted on a hybrid vehicle provided with an engine and a motor generator coupled with the engine. The vibration damping control apparatus (i) calculates pulsating torque of the engine and inertia torque of the engine, (ii) sets, as consumption torque, a value obtained by subtracting the inertia torque from the pulsating torque, (iii) sets, as shaft torque of an output shaft of the engine, a value obtained by subtracting the consumption torque from base torque of the motor generator, (iv) calculates vibration damping torque which is torque for suppressing a variation in the shaft, and (v) controls the motor generator such that torque outputted from the motor generator is a sum of the base torque and the vibration damping torque.

1. 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:
an ECU configured to calculate a pulsating torque of the engine; to calculate a first inertia torque which is an inertia torque of the engine; to set, as a consumption torque, a value obtained by subtracting the calculated first inertia torque from the calculated pulsating torque; to set, as a shaft torque of an output shaft of the engine, a value obtained by subtracting the calculated consumption torque from a base torque of the motor generator, and to calculate a vibration damping torque which is a torque for suppressing a variation in the shaft torque; and to control the motor generator such that a torque outputted from the motor generator is a sum of the base torque and the calculated vibration damping torque.
