Abstract
A vibration control apparatus for a vehicle equipped with a power unit and a vehicle body is comprised of an active engine mount disposed between the power unit and the vehicle body. A controller is connected to a vehicle body vibration detector, a passenger compartment vibration detector and a drive force detector. The vehicle body vibration detector detects a vibration transmitted from the power unit to the vehicle body through the active engine mount. The passenger compartment vibration detector detects a vibration of a member defining a passenger compartment of the vehicle. The drive force detector detects as to whether driving force of the power unit is transmitted to driving wheels. The controller controls the active engine mount to reduce the passenger compartment vibration when the driving force is transmitted to the driving wheels and to reduce the vehicle body vibration when the driving force is not transmitted to the driving wheels.
