ABSTRACT:
A damping method for a hybrid vehicle in which a power unit consisting of an engine and a motor is supported in a vehicle body frame via an active vibration isolation support system includes: a step of firstly damping vibration of the power unit by the active vibration isolation support system; and a subsequent step of controlling operation of the motor to damp vibration that has not been eliminated by the active vibration isolation support system. Therefore, it is possible to prevent the damping effect from being degraded by interference between the damping control by the active vibration isolation support system and the damping control by the motor, and to reduce the total power consumption by preferentially operating the active vibration isolation support system which has low power consumption, and secondarily operating the motor which has high power consumption.
