摘要： A vehicle sound effect generation apparatus generates a sound effect of an engine based on a vibration sound map including a fundamental wave sound having a fundamental frequency component and a plurality of adjustment wave sounds having a frequency component other than the fundamental frequency component. The vehicle sound effect generation apparatus includes a running state detecting unit that detects a running state of a vehicle; a lateral input amount setting unit that sets, based on the running state detected by the running state detecting unit, a lateral input amount in which a physical amount relating to at least one of a movement of the vehicle in a width direction and a movement of the vehicle in a turning direction is a parameter; an adjustment wave sound selector that selects one or more half-order adjustment wave sounds having a half-order frequency component, based on the lateral input amount; and a sound effect generation unit that synthesizes the fundamental wave sound with the one or more half-order adjustment wave sounds selected.

摘要： A device and method that is configured to operate an active noise reduction system for a motor vehicle, where there is an active noise reduction system input signal that is related to the vehicle engine speed, and where the active noise reduction system comprises one or more adaptive filters that use a filter coefficient to modify the amplitude and/or phase of a noise cancellation reference signal and output noise reduction signals that are used to drive one or more transducers with their outputs directed to reduce engine noise, where the value of the coefficient is related to an adaptive filter leakage factor. Changes in the engine speed, based on the input signal that is related to the vehicle engine operation, are monitored. In response to changes in the engine speed, the adaptive filter leakage factor is temporarily modified.

摘要： A vibration/noise control system controls vibrations and noises generated with a periodicity or a quasi-periodicity from a vibration/noise source having a rotating member. A W filter formed by an adaptive digital filter generates a control signal for controlling the vibrations and noises. A self-expanding engine mount is arranged in a vibration/noise transmission path and converts the control signal into a driving signal for driving the vibration/noise source. A vibration/noise error sensor detects an error signal indicative of a difference between the driving signal and the vibrations and noises. A C filter stores a transfer characteristic of a portion of the vibration/noise transmission path extending between the W filter and the error sensor, and generates a reference signal based on the transfer characteristic. An LMS processing block updates the W filter coefficient, i.e. the control signal such that the error signal is made minimum, based on the error signal, reference signal and W filter coefficient. An H system-identifying filter identifies a dynamic characteristic of a physical system extending between the W filter and a predetermined control area, and a C system-identifying filter identifies a dynamic characteristic of the above portion of the vibration/noise transmission path. The C filter coefficient is updated based on results of identification by the C system-identifying filter. The H system- and C system-identifying filters each include an adaptive digital filter, of which the filter coefficient is updated by the use of a genetic algorithm.

摘要： The method of noise attenuation comprises the steps of generating a noise canceling signal, sensing for an system condition, and ceasing the generation of the noise canceling based upon the system condition. This method is embodied in a system that includes an air induction body (10), a speaker (14) in proximity to the air induction body (10), a sensor (16, 27) for sensing a system condition, and a control unit (18) with a noise cancellation feature. The control unit (18) is in communication with both the speaker (14) and the sensor (26,27). Based upon the sensed system condition, the control unit (18) may disable the noise cancellation feature.

摘要： A vibration control system includes a processor-based circuit which monitors and controls an analog vibration control circuit. The system includes a sensor to detect the undesirable vibrations and a synchronous pulse generator for determining the fundamental frequency of the vibrations emitted by the source. An actuator produces anti-noise to counter unwanted vibrations. The processor circuit tests the system, monitors system functions, and adjusts various parameters to provide optimal performance.

摘要： A control system provides active attenuation of excitations to a region or structure (1). A feedback sensor (14) generates a signal in response to excitations of the region (1) which is fed to a narrow-band feedback controller (5) having a frequency detector (4), a bandpass filter (6) controlled by the frequency detector (4), and a feedback control generator (8). The frequency detector (4) determines the peak frequency of the excitations. A bandpass filter (6) passes only those signals from the feedback sensor (14) in a narrow frequency band adjustably controlled by the frequency detector (4). The feedback control generator (8) receives the filtered signal from the bandpass filter (6) and produces a control output used by an actuator (13) to attenuate the excitations. Several bandpass filters (6) can be used in parallel to attenuate several frequency bands if the excitation source has a plurality of peaks. This configuration allows the bands to move across the frequency spectrum in response to the excitations.

摘要： A vibration/noise control system controls vibrations and noises generated with a periodicity or a quasi-periodicity from a vibration/noise source having at least a rotating member. A self-expanding engine mount is arranged in at least one of vibration/noise transmission paths and is driven by a driving signal generated by the system. A vibration error sensor detects an error signal exhibiting a difference between the driving signal and the vibrations and noises. A reference sine wave is generated, which is superposed on a control signal for controlling the vibration/noise source, to thereby drive the self-expanding engine mount. A transfer characteristic of a portion of at least one of the vibration/noise transmission paths is identified based on the reference sine wave, a delayed sine wave delayed by a predetermined delay period M relative to the reference sine wave, and the error signal. The transfer characteristic stored is updated based on an identification signal output from an identifying filter formed by an adaptive digital filter having two taps. The predetermined delay period M is set relative to the repetition period of the reference sine wave in a range of 1/3 >/= M >/= 1/7, wherein M is a real number.
