<P>PROBLEM TO BE SOLVED: To provide a vibration reducing system and method for reducing vibration at a predetermined position in a vehicle by automatically switching control of vibration of an engine and control of rotational vibration of a tire. <P>SOLUTION: A control device 11: generates a first extraction signal in which a signal frequency is a real number of times of a rotation speed signal based on a signal obtained from a sensor 15 for determination and the rotation speed signal from a sensor 7 which measures the rotation speed of a wheel; generates a second extraction signal in which a signal frequency is a real number of times of a rotation speed signal based on a signal obtained from a sensor 15 for determination and the rotation speed signal from a sensor 6 which measures the rotation speed of an engine; compares the first extraction signal with the second extraction signal; controls ACMs 3a and 3b according to the compared result; and reduces the vibration produced at a predetermined position in the vehicle 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
