摘要： 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.

摘要： 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.

摘要： A subtractor subtracts a first control signal output from a first bandpass filter from an error signal, and supplies a differential signal to a second bandpass filter. The second bandpass filter, which has a central frequency of 70 Hz, is affected by an operation of the first bandpass filter, i.e., a first control signal, which has a central frequency of 40 Hz. The first bandpass filter is not affected by an operation of the second bandpass filter, i.e., the second control signal.

摘要： While a vehicle incorporating an active vibration noise control apparatus is decelerating, hysteresis is given if an operating point moves from an operating point on a sampling period characteristic curve to an operating point on another sampling period characteristic curve. Even if a base period detected depending on noise contains fluctuations, a smooth noise control process is performed. Since a division number produced when the base period is divided by a sampling period is a real number, the freedom of design is widened. Less strict limits are posed on the processing capability of a CPU of the active vibration noise control apparatus to provide a wider control range.
摘要翻译： 当包含主动振动噪声控制装置的车辆正在减速时，如果工作点从采样周期特性曲线上的工作点移动到另一个采样周期特性曲线上的工作点，则给出滞后。 即使根据噪声检测到的基准周期包含波动，也执行平滑的噪声控制处理。 由于在基准周期除以采样周期之后产生的分割数是实数，因此设计的自由度变宽。 对主动振动噪声控制装置的CPU的处理能力不严格的限制提供更宽的控制范围。

摘要： In a motor-assisted hybrid vehicle, an active vibration control system suppresses torque fluctuations of an engine without detriment to the response of a static torque. An adaptive notch filter outputs a control signal depending on a harmonic basic signal generated by a basic signal generator from a rotational frequency of a crankshaft. A combiner combines the control signal with a drive signal for the generator motor and supplies the combined signal through a power controller to the generator motor. The basic signal is supplied to corrective filters having the transfer function of the generator motor to output a reference signal. The filter coefficient of an adaptive notch filter is successively updated so that an error signal representative of a rotational speed fluctuation of the crankshaft will be minimized.

摘要： A subtractor subtracts an echo canceling signal Ĉ·yl(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.
