Abstract

See full text

Methods and systems are provided for diagnosing whether active engine mounts configured to isolate engine vibration from a cabin and chassis of a vehicle are functioning as desired. In one example, engine vibrations are actively induced, and the active engine mounts are alternately controlled to a first, dampening mode, and to a second, stiffening mode for predetermined time periods, where resultant chassis vibrations are monitored during the predetermined time periods. By monitoring chassis vibrations as a function of induced engine vibrations, and further responsive to the active engine mounts being controlled to the first and second modes, it may be indicated as to whether the active engine mounts are functioning as desired.
