Abstract
Methods and systems for adjusting a tuning state of a pendulum damper are provided. In one example, an engine system is provided that includes a crankshaft coupled to a plurality of pistons in a plurality of cylinders. The crankshaft includes a plurality of pendulums coupled to a plurality of cheeks and a pendulum tuning mechanism coupled to an associated pendulum included in the plurality of pendulums or coupled to an associated pendulum in a torque converter and configured to tune damping characteristics of the associated pendulum based on an engine order.
