  • Patent number: 6018689
    Abstract: Described are a vibration actively reducing apparatus and a method for identifying a transfer function in the vibration actively reducing apparatus. An identification signal which is a quantization of at least one sinusoidal wave is supplied from a controller of the vibration actively reducing apparatus to a controlled vibration source in synchronization with a predetermined output sampling clock (SCo) to develop an identification vibration therefrom. The controller reads a residual vibration signal from a residual vibration detector of the actively reducing apparatus in synchronization with a predetermined input sampling clock (SCi). After read of the residual vibration signal as a time series data for each frequency, an FFT calculation is carried out for each time series data to extract a frequency component of the original sinusoidal wave.

  • Patent number: 5950756
    Abstract: Described is a vibration isolator of a vibration actively reducing apparatus which achieves a more accurate detection of a residual vibration by means of a load sensor after an interference of a controlled vibration developed from a controlled vibration source constituting the vibration isolator against a vibration developed and transmitted from a vibration source such as a vehicular engine. In the vibration isolator, all vibration forces developed and transmitted from the vibration source are once concentrated onto a predetermined rigidity member such as a yoke of an electromagnetic actuator constituting the controlled vibration source and the load sensor is installed between the predetermined rigidity member and a lid member of the vibration isolator coupled to a supporting base member attached onto, for example, a vehicle body.

  • Patent number: 5792948
    Abstract: A vibration control apparatus for a vehicle equipped with a power unit and a vehicle body is comprised of an active engine mount disposed between the power unit and the vehicle body. A controller is connected to a vehicle body vibration detector, a passenger compartment vibration detector and a drive force detector. The vehicle body vibration detector detects a vibration transmitted from the power unit to the vehicle body through the active engine mount. The passenger compartment vibration detector detects a vibration of a member defining a passenger compartment of the vehicle. The drive force detector detects as to whether driving force of the power unit is transmitted to driving wheels. The controller controls the active engine mount to reduce the passenger compartment vibration when the driving force is transmitted to the driving wheels and to reduce the vehicle body vibration when the driving force is not transmitted to the driving wheels.

  • Patent number: 5647579
    Abstract: A control type vibro-isolating support includes a pulse signal generator for generating reference signals x, which represent the state of the vibration being generated by an engine. An acceleration sensor detects residual vibration on the support member side, and generates a residual vibration signal e. A controller is supplied with the reference signals x and residual vibration signal e. On the basis of the reference signals x and residual vibration signal e and in accordance with, for example, synchronous filtered X LMS algorithm, the controller generates a drive signal y so as to lower the vibration level on the member side. An engine mount is interposed between the engine and the member, and has an electromagnetic actuator. The drive circuit for the actuator is supplied with the drive signal y.
