摘要： A frequency detecting circuit estimates the frequency fp of a propeller shaft based on the frequency fc of vehicle speed pulses, and calculates a control frequency fp′ which is a harmonic of the frequency fp. A basic signal generator generates a basic cosine wave signal xp1 and a basic sine wave signal xp2 of the control frequency fp′. Adaptive filters and an adder generate a control signal Scp for canceling a driveline noise produced in a passenger compartment by the propeller shaft. A speaker outputs a canceling sound based on the control signal Scp into the passenger compartment.

摘要： 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.

摘要： A processor determines an engagement state of a clutch based on a clutch signal, which is output from a clutch switch connected to a clutch pedal. In a declutching state, the processor lowers weighting gain characteristics that serve as acoustic correcting characteristics used in a sound pressure adjuster. Therefore, even when a change of an engine rotational frequency per unit of time increases during a shift-change operation, the gain of the control signal is prevented from increasing. Accordingly, a gap between real acceleration of the vehicle and a sound effect output from a speaker can be decreased, thereby reducing the possibility that the driver and/or a passenger in the vehicle may feel a sense of strangeness relative to the sound effect.

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 from a canceling error signal to estimate the resonant noise to be silenced at a position of a microphone, and outputs a first basic signal representing the estimated resonant noise as an input signal supplied to a controller. In the controller, a delay filter generates a second basic signal by delaying the first basic signal by a time value. The controller generates a control signal based on the first basic signal and the second basic signal.
