Abstract
Methods and systems are provided for a dual state hydromount in order to passively introduce air underneath a decoupler such that the stiffness of the air pocket adds to the stiffness of the decoupler, thereby increasing a level of damping available in a vehicle ride mode, the ride mode defined by vehicle speeds greater than a threshold speed. In one example, a dual state hydromount is described wherein a partitioning structure may be alternately coupled to either vacuum or atmosphere, and when coupled to atmosphere an air spring is created under the decoupler via the passive directing of air to the decoupler via a one way check valve. In this way, introduction of an air spring is achieved without additional active control.
