    • An active vibration insulator includes an electromagnetic actuator, a control-signals generating device, a driver, a calculator, and a judging device. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generating device generates cyclic control signals based on cyclic pulsating signals output from a vibration generating source of a vehicle. The cyclic control signals actively inhibit vibrations generated by the vibration generating source from transmitting to a specific part of the vehicle. The driver drives the electromagnetic actuator by making the electric-current supplies variable based on the cyclic control signals. The calculator calculates an estimated transfer function composed of estimated values of a transfer function for a transfer system including the electromagnetic actuator and the driver. The judging device judges an inoperative malfunction of the electromagnetic actuator based the estimated transfer function.
    • 主动振动绝缘体包括电磁致动器,控制信号产生装置,驱动器,计算器和判断装置。 电磁执行器根据电流供应产生振动。 控制信号生成装置基于从车辆的振动发生源输出的循环脉动信号生成循环控制信号。 循环控制信号主动地抑制振动发生源产生的振动,从而传递到车辆的特定部分。 驱动器通过使电流供应器基于循环控制信号而变化来驱动电磁致动器。 计算器计算由包括电磁致动器和驱动器的传送系统的传递函数的估计值组成的估计传递函数。 判断装置基于估计的传递函数来判断电磁致动器的不操作故障。
