Abstract:
Methods and systems are provided for controlling an active vibration system. In one embodiment, a method of controlling an active vibration system associated with an engine is provided. The method includes: receiving engine parameters indicating one or more engine operating conditions; determining an operating mode of the active vibration system to be at least one of a sensing mode and a force generation mode based on the engine parameters; and selectively controlling the active vibration system based on the operating mode.
