PURPOSE: To suitably cope with abnormalities such as failures or deterioration, so as to improve reliability of a system, by detecting abnormalities of a control- type vibration controlling supporting device, and changing a control state of a control means according to the detected result. CONSTITUTION: A reference signal (x) of a pulse signal generator 21 is supplied as a signal for indicating a generating state of vibration in an engine 30 to a controller 20, and a remaining vibration signal (e) of an acceleration sensor 22 fixed on a member 35 is supplied as a signal for indicating vibration after interference to the controller 20. The controller 20 outputs a driving signal (y) on the basis of the reference signal (x) and the remaining vibration signal (e) so that vibration to be transmitted to the member 35 from the engine 30 through an engine mount 1 may be decreased. A leakage sensor 23 supplies a leakage detecting signal (q) of fluid in a fluid chamber 15 to the controller 20. The controller 20 performs control prohibiting processing or level decreasing processing when it detects abnormalities from an acceleration signal (a) of an acceleration sensor 24 and a temperature detecting signal (t) of a temperature sensor 25. |
