Methods of attenuating vibration transfer to a passenger compartment

A method of attenuating vibration transfer to a body of a vehicle using a dynamic mass of the vehicle, and the vehicle includes at least one wheel, the method comprising:

• receiving angular position information regarding change in angular position of the wheel over a time interval, wherein the angular position information is used to determine an angular frequency of the wheel;
• determining, based on the angular position information, an instantaneous angular velocity that corresponds to a particular angular frequency of the wheel, and an angular position that corresponds to the wheel;
• generating a gain-and-phase-compensated actuator drive command to counteract a vibration that occurs at the particular angular frequency of the wheel, which is based on the instantaneous angular velocity and the angular position of the wheel;
• communicating the gain-and-phase-compensated actuator drive command to a hydraulic mount assembly that supports the dynamic mass;
• energizing a magnetic apparatus of an actuator of the hydraulic mount assembly which moves a plug to a displaced position to correspondingly lock a casing to a first plate in a secondary position, and locking the casing in the secondary position locks a decoupler to the first plate such that the decoupler abuts the first plate which causes hydraulic action to occur through first and second chambers of the hydraulic mount assembly via an inertia track of the hydraulic mount assembly;
• positioning the plug in a central position after locking the casing in the secondary position, wherein the central position is different from the displaced position;
• and
• wherein energizing the magnetic apparatus further comprises energizing the magnetic apparatus to change an amount of current to coils that magnetically interacts with magnets to cause fluctuation of the plug from the central position while the casing remains in the secondary position in order to minimize the vibration transfer to the body due to the vibration that occurs at the particular angular frequency of the wheel in response to the gain-and-phase-compensated actuator drive command.
