PROBLEM TO BE SOLVED: To make adaptive control so that the vibratory transmission lessens both in the left and the right engine mount even in case any of the error sensors goes in failure. SOLUTION: Engine mounts 6a and 6b are installed on an engine 4 symmetrically to the left and right and are equipped with respective error sensors 8a and 8b. Controllers 9a and 9b include fixed filters 93a and 93b, adaptive filters 95a and 95b, and changeover parts 96a and 96b. Usually electromagnetic actuators are operated based upon the control algorithm including the transfer function between the electromagnetic actuator of each engine mount and corresponding error sensor, but one of the error sensors is judged to be failed by a failure judging part 11 for the engine mount on the failed side, the electromagnetic actuator of the failed side engine mount is put under adaptive control based upon the control algorithm including the transfer characteristic presumptive value between the applicable actuator and the other error sensor on the normal side. |
