PURPOSE: To cause a vibration reduction device to perform an optimum vibration reducing operation according to combustion conditions of an engine in reducing vibration of a vehicle by means of vibration of the opposite phase to and the same amplitude as said vibration.
CONSTITUTION: The filter factor of a correction filter 30 for determining combustion conditions of an engine, such as Air-fuel ratio, intake pipe length and a supercharged state, is corrected by an adjusting mechanism 26 according to the operating states of the engine, so as to correct a drive signal A transmitted to an actuator 3 for vibrating the vehicle body. Vibrating control which corresponds to vehicle vibration governed by the combustion conditions of the engine is thereby performed.
