摘要： An active road noise control includes generating with a sensor arrangement a primary sense signal representative of accelerations, motions and/or vibrations that occur at a first position on a vehicle body, and providing a noise reducing signal by processing the primary sense signal according to an adaptive mode of operation or a non-adaptive mode of operation. It includes generating within the vehicle body noise reducing sound at the second position from the noise reducing signal, and evaluating the primary sense signal and controlling the processing of the primary sense signal so that the primary sense signal is processed in the adaptive mode of operation when the magnitude of the primary sense signal undercuts a first threshold and in the non-adaptive mode of operation when the magnitude of the primary sense signal exceeds a second threshold, the first threshold being equal to or smaller than the second threshold.

摘要： An active noise control device (12) detects composite vibration of a vibration transmitting route (30) to which both vibration of a rotating body (E) caused by generation or transmission of drive force of a vehicle (10) and vibration of a wheel (26) generated by contact between the wheel (26) and a road surface (R) are transmitted. A first reference signal (Sbc) for defining a reference waveform of a canceling sound (CS) for canceling vibration noise (NZc) in a vehicle interior is generated based on the composite vibration. The component of the canceling sound (CS) for canceling vibration noise (NZe) of the rotating body (E) is removed from the first reference signal (Sbc) to generate a second reference signal (Sbr) for defining a reference waveform of the canceling sound (CS) for canceling vibration noise (NZr) of the wheel (26). The canceling sound (CS) is outputted based on the second reference signal (Sbr).

摘要： Die vorliegende Erfindung betrifft eine Vorrichtung zur Verminderung bestimmter Geräuschanteile in dem von einem Kraftfahrzeug emittierten Reifen/Fahrbahngeräusch, wobei im Bereich von Abstrahleinrichtungen des Reifen/Fahrbahngeräusches als Resonator ausgebildete Schallabsorber angeordnet sind, die auf Geräuschanteile, deren Frequenzen sich proportional zur Raddrehzahl ändern, abstimmbar sind. Zwei von drei alternativen Varianten der Erfindung setzen ein ABS-Bremssystem voraus. Um die Schallleistung, die von Reifen bei bestimmten Frequenzen, die sich proportional zur Raddrehzahl ändern, zu mindern, und so das Reifen/Fahrbahngeräusch zu vermindern, wird erfindungsgemäß vorgeschlagen, daß die Resonatoren am Fahrzeug an der Innenwand des Radkastens angebracht sind und in ihrer Anzahl, ihren Einzelvolumina und/oder ihren Impedanzen unter Zwischenschaltung einer Steuer- und/oder Regelelektronik an den geschwindigkeitsabhängigen Bedarf angepaßt werden.

摘要： Exemplary road and engine noise control systems and methods include directly picking up road noise from a structural element of a vehicle to generate a first sense signal representative of the road noise, directly picking up engine noise from an engine of the vehicle to generate a second sense signal representative of the engine noise, and combining the first sense signal and the second sense signal to provide a combination signal representing the combination of the first sense signal and the second sense signal. The systems and methods further include broadband active noise control filtering to generate a filtered combination signal from the combination signal, converting the filtered combination signal provided by the active noise control filtering into anti-noise and radiating the anti-noise to a listening position in an interior of the vehicle. The filtered combination signal is configured so that the anti-noise reduces the road noise and engine noise at the listening position.
