摘要： 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.

摘要： An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.

摘要： An active vibration insulator includes an electromagnetic actuator, a control-signals generator, a control-signals compensator, and a driver. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The control-signals generator generates control signals, which actively inhibit vibrations generated by a vibration generating source of a vehicle from transmitting to a specific part of the vehicle, based on cyclic pulsating signals output from the vibration generating source. The control-signals compensator compensates the cyclic control signals, which the control-signals generator generates, depending on output voltages of a battery. The driver is connected between the battery and the electromagnetic actuator, and makes the electric-current supplies variable based on the cyclic control signals, which the control-signals compensator has compensated, and the output voltages of the battery, thereby driving the electromagnetic actuator.

摘要： An active vibration insulator includes an electromagnetic actuator, a cyclic-control-signals output device, and an electromagnetic-actuator driver. The electromagnetic-actuator driver includes an asymmetric half-bridge circuit, and an actuating-signals output device. The actuating-signal output device outputs a signal for turning on one of a high-side switch and a low-side switch of the asymmetric half-bridge circuit, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation based on the cyclic control signals, which the cyclic-control-signals output device outputs, or outputs a pulse-width-modulated actuating signal for actuating both of them by means of pulse-width modulation when the cyclic control signals are positive. Moreover, the actuating-signal output device outputs a signal for turning off one of them, and outputs a pulse-width-modulated actuating signal for actuating the other one of them by means of pulse-width modulation when the cyclic control signals are negative.
