Abstract
A vibration damping system for a vehicle has a vibration sensor which detects vibration of solid elements on the vehicle and vibration of air inside the vehicle. A first vibrator supports a power unit relative to the vehicle body and directly vibrates the vehicle body. A second vibrator directly vibrates air inside the vehicle body. A drive control unit performs calculation on the basis of a detecting signal from the vibration sensor and controls the first and the second vibrators on the basis of the result of the calculation so that the vibration of the solid element and the vibration of air inside the vehicle body are damped. The vibrator control ratio of the first and second vibrators is changed according to the condition of a predetermined factor of the vehicle.
