摘要： An apparatus for reducing periodical noises transmitted from a noise source into a vehicle passenger compartment. The apparatus comprises control sound sources for producing control sounds in the vehicle passenger compartment, residual noise sensors for detecting the residual noises in the vehicle passenger compartment, transfer function filters modeled on transfer function between the control sound sources and the residual noise sensors, and adaptive digital filters having variable filter coefficients. A reference signal is produced in the form of a series of impulses having the same period as the noises. The transfer function filters are convoluted with the reference signal to produce reference processed signals. The adaptive digital filters are convoluted with the reference signal to generate drive signals to drive the control sound sources. The filter coefficients of the respective adaptive digital filters are updated based on the processed reference signals and the residual noises to reduce the noises in the vehicle passenger compartment.

摘要： A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.

摘要： In order to attenuate vibration which tends to be transmitted from a power unit to a vehicle passenger during the idling mode of engine operation, ERF filled engine mounts are arranged so that when neither of two orifice passages are restricted by impressing a voltage on ERF viscosity control electrodes included therein, the frequency at which the dynamic spring constant exhibits a minimum value is the same as the frequency at which the vibration transmission phase maximizes while one of the two orifice passages is restricted by the application of a voltage on the set of electrodes disposed therein. Rapid cyclic control of the dynamic spring constant and the vibration transmission phase for each mount used to support a power unit is carried out. This enables a desirable compromise in the control of the two different parameters.

摘要： In the disk brake, mounting portions of the caliper of a disk brake extending toward the entrance side and the exit side with respect to the rotation direction of the disk. Relative to the rotation direction, the length of the mounting portion on the entrance side is greater than that of the mounting portion on the exit side so that the cylinder portion is offset toward the exit side. Further, the mounting portion on the entrance side has thickenings formed to extend in a longitudinal direction thereof, so that with respect to the direction of the axis of the disk, the thickness of the mounting portion on the entrance side is greater than that of the mounting portion on the exit side. During braking, when a bending moment acts on the caliper, which can cause inclination of the caliper relative to the disk, flexural rigidity of the mounting portion on the entrance side is higher than that of the mounting portion on the exit side.

摘要： An apparatus for active reduction of noises transmitted from a noise source into a space. The active noise reduction apparatus comprises residual noise sensors for detecting the residual noises in the space. A reference signal is produced based upon the noise generating condition of the noise source. The reference signal is used, along with the detected residual noises, to drive control sound sources so as to reduce the noises in the space. A filter is adjusted to correspond to acoustic transfer characteristics between the control sound sources and the residual noise sensors. An identification sound is generated to correspond to the background noise level detected in the space and to the spectral distribution of the noises transmitted into the space. The coefficients of the filter are updated according to acoustic transfer characteristics between the control sound sources and the residual noise sensors. The acoustic transfer characteristics are obtained based upon the identification sound and the residual noises.
