Active vibration damping system for a vehicle

A vibration damping system for a vehicle comprising

• a vibration detecting means which detects vibration of solid elements on the vehicle and vibration of air inside the vehicle,
• a vibrator group consisting of a first vibrator which supports a power unit relative to the vehicle body and directly vibrates the vehicle body and a second vibrator which directly vibrates air inside the vehicle body, and
• a drive control means which performs calculation on the basis of a detecting signal from the vibration detecting means and outputs a single drive signal to the vibrator group in accordance with the calculation, and
• a drive signal separating means which separates the single drive signal by frequency into first and second drive signals for the first and second vibrators forming the vibrator group,
• the first and second vibrators forming the vibrator group being driven respectively by the first and second drive signals.

A vibration damping system for a vehicle comprising

• a vibration sensor group consisting of a first vibration sensor which detects vibration of solid elements on the vehicle and a second vibration sensor which detects vibration of air inside the vehicle,
• a vibrator group consisting of a first vibrator which supports a power unit relative to the vehicle body and directly vibrates the vehicle body and a second vibrator which directly vibrates air inside the vehicle body,
• a detecting signal mixing means which mixes detecting signals of the first and second vibration sensors into a detecting signal,
• a drive control means which performs calculation on the basis of the detecting signal from the detecting signal mixing means and outputs a single drive signal to the vibrator group in accordance with the calculation which single drive signal drives the first and the second vibrators forming the vibrator group so that the vibration of the solid element and the vibration of air inside the vehicle body are damped, and
• a drive signal separating means with separates the single drive signal by frequency into first and second drive signals for the first and second vibrators forming the vibrator group,
• the first and second vibrators forming the vibrator group being driven respectively by the first and second drive signals.
