摘要： A vibration damping system for a vehicle includes a vibration sensor which detects vibration of a predetermined vibrating element on the vehicle, a vibrator which vibrates the vibrating element, and a drive control unit which controls the vibrator on the basis of the detecting signal from the vibration sensor so that a predetermined object vibration component of the vibration of the vibrating element is damped by the vibration generated by the vibrator. The drive control unit is restrained from controlling the vibrator according to the condition of a predetermined factor of the vehicle.

摘要： PCT No. PCT/GB92/01399 Sec. 371 Date May 26, 1994 Sec. 102(e) Date May 26, 1994 PCT Filed Jul. 28, 1992 PCT Pub. No. WO93/03479 PCT Pub. Date Feb. 18, 1993A system for reducing periodic noise, which includes a plurality of harmonically related noise signals, comprises an actuator for producing a canceling acoustic signal, a sensor for detecting a residual noise signal, a synchronizing signal generator and processing circuitry. The processing circuitry comprises a plurality of tunable harmonically related band pass filters, a tuning signal generator and a summer which sums the outputs of the filters. The tuning signal generator receives the synchronizing signal from the synchronizing signal generator and outputs the tuning signals to the band pass filters. As the frequency of the synchronizing signal changes, the tuning signal generator causes the tunable filters to track harmonics of the noise to be canceled. After summing by the summer and suitable amplification, the outputs from the filters are used to drive the actuator so as to reduce the residual noise detected by the sensor.

摘要： A vibration damping system for a vehicle includes a vibration sensor which detects vibration of a particular vibrating element, an actuator which applies vibration to the particular vibrating element and a controller which receives a vibration signal output from the vibration sensor and controls the actuator to apply to the particular vibrating element such vibration that damps the vibration detected by the vibration sensor. The controller is provided with a sensitivity changing circuit which changes the sensitivity of the vibration sensor according to a predetermined condition of the vehicle.
