1. A vehicle comprising:
a vehicle frame;
a cabin;
an engine; and
a plurality of vibration control devices mounted on the vehicle frame, each vibration control device comprising a circular force generator comprising at least one mass and at least one motor configured to rotate the mass, wherein the vibration control devices are configured to perform active vibration control to reduce noise and/or vibration within the cabin resulting from the engine deactivating a subset of cylinders in operation.
