Pneumatic resonator and accumulator system for control of turbocharger wastegate movement

A wastegate system of a vehicle, comprising:

• a wastegate valve configured to regulate exhaust flow through a turbine of a turbocharger of an engine;
• a wastegate actuator including a lever that is mechanically coupled to the wastegate valve via one or more linkages and that is configured to move linearly based on a pressure within an interior of the wastegate actuator;
• a resonator that is fluidly coupled to the interior of the wastegate actuator via a first one or more hoses and that is configured to damp motion of the lever, the one or more linkages, and the wastegate valve attributable to pressure changes in the exhaust from combustion events within the engine;
• a pneumatic source;
• a regulator valve that is configured to regulate the pressure within the interior of the wastegate actuator;
• and
• an accumulator that is fluidly coupled to the regulator valve via a second one or more hoses, that is fluidly coupled to the pneumatic source via a third one or more hoses, and that is configured to damp pressure changes from the pneumatic source,
• wherein wastegate actuator further includes a spring configured to oppose the pressure within the interior of the wastegate actuator.
