    Abstract: An active noise/vibration/sound control system for a vehicle has an ANC (active noise control apparatus), an AVC (active vibration control apparatus), and an ASC (active sound control apparatus). To prevent the ANC, the AVC, and the ASC from interfering with each other and hence to prevent vehicle cabin environment of vibrations, noise, and sound from being impaired, activation and inactivation of the ANC, the AVC, and the ASC are controlled or their control characteristics are controlled in relation to each other by a weighting variable calculator as a coordination controller, depending on an engine rotation frequency and a frequency change which are representative of a running state of the vehicle as detected by an engine rotation frequency detector and a frequency change detector that serve as a running state detector.

    Abstract: An active noise control device detects composite vibration of a vibration transmitting route to which both vibration of a rotating body caused by generation or transmission of drive force of a vehicle and vibration of a wheel generated by contact between the wheel and a road surface are transmitted. A first reference signal for defining a reference waveform of a canceling sound for canceling vibration noise in a vehicle interior is generated based on the composite vibration. The component of the canceling sound for canceling vibration noise of the rotating body is removed from the first reference signal to generate a second reference signal for defining a reference waveform of the canceling sound for canceling vibration noise of the wheel. The canceling sound is outputted based on the second reference signal.

    Abstract: On an active noise controller, an adjustment reference signal generator generates an adjustment reference signal Sra by reading the waveform data sequentially at a read location shifted by a given amount from a read location for a reference signal Sr with respect to the waveform data at a reference signal generator. A one-tap adaptive filter generates a control signal Scp by multiplying the adjustment reference signal Sra by a filter factor W. A gain controller outputs a compensation control signal Sca generated by multiplying the control signal Scp by gain G. A speaker outputs the compensation control signal Sca as a cancellation sound.

    Abstract: An active vibration/noise control device which is provided with a plurality of cancel signal generation parts for generating output signals for respectively cancelling noises generated at a plurality of vibration/noise generation sources. The effect of the suspension of either of first and second cancel signal generation parts on the other is reduced. According to the operating state of the first cancel signal generation part, the simulated transmission properties of the second cancel signal generation part are adjusted. Consequently, without regard to the operating state of the first cancel signal generation part, the noise control performance of the second cancel signal generation part can be maintained.

    Abstract: A subtractor subtracts an echo canceling signal Ĉ·y1(n−1) from a canceling error signal e(n) to estimate a residual noise to be silenced at the position of a microphone, and outputs a first basic signal x1(n) representing the residual noise. A first control circuit section generates a first control signal y1(n) based on the first basic signal x1(n) and a second basic signal x2(n) that is generated by delaying the first basic signal x1(n) by a time Z−n. A second circuit section generates a second control signal y2(n) based on the first basic signal x1(n) and an engine rotation signal.

    Abstract: When the frequency of an engine rotation signal reaches a predetermined frequency, a comparator of a switching unit outputs a switching control signal to selectors and a filter coefficient updater. Based on the switching control signal, the selector switches from a connection between one memory and a corrector to a connection between another memory and the corrector, thereby changing the transfer characteristics C^rr of the corrector from C^11 to C^10. Based on the switching control signal, the selector switches from a connection between one ADC and a filter coefficient updater to the connection between another ADC and the filter coefficient updater, thereby supplying the filter coefficient updater with an error signal, rather than an error signal.
