Abstract
The status of a lock-up clutch included in an automotive power unit T/C is monitored. In the event that the lock-up clutch is partially locked up or conditioned to produce so called 'slip lock-up', ERF (electroheopectic fluid) filled engine mounts are conditioned to produce an increased amount of rigidity, while in the event that the lock-up clutch is fully engaged the engine mounts are induced to assume a more flexible state. In addition to this engine idling and shake, vibration can be attenuated by sensing the relative displacement between the power unit and the chassis.
