    Abstract: A spring-damper assembly for a suspension corner employed in a vehicle having a vehicle body and a road wheel includes a fluid spring configured to suspend the vehicle body relative to the road wheel. The spring-damper assembly also includes a damper configured to attenuate compression and rebound oscillations of the fluid spring. The spring-damper assembly additionally includes a spring-seat housing configured to retain the fluid spring and establish a position of the fluid spring relative to the damper. The spring-seat housing includes an inner surface defining a contour configured to guide the fluid spring upon compression thereof around the damper and define a non-linear stiffness of the fluid spring. A vehicle having such a spring-damper assembly is also provided.

    Abstract: A method for shifting tandem axle loads on a vehicle including an air suspension circuit having a three way valve, a first air spring connected between a drive axle of a tandem and a vehicle frame and a second air spring connected between a tag axle of the tandem and the vehicle frame. A diameter of the first air spring is larger than a diameter of the second air spring. The system also has an air supply, a first fluid line connected between a port one of the three way valve and the first air spring and a second fluid line connected between a port three of the three way valve and the second air spring.

    Abstract: A method of controlling a compressor for an air suspension of an electric vehicle includes: determining a state of a reservoir in the electric vehicle, the reservoir coupled to drive air springs of a suspension system; determining whether the electric vehicle is connected to an external source of electric energy for charging an energy storage of the electric vehicle; in response to determining that the electric vehicle is connected to the external source, applying a first value as a threshold for whether to replenish the reservoir by a compressor; and in response to determining that the electric vehicle is not connected to the external source, applying a second value, different from the first value, as the threshold for whether to replenish the reservoir by the compressor.

    Abstract: A vehicle has a frame, at least two wheels, at least one front and one rear suspension assembly, at least one of the suspension assemblies including an air spring, an air compressor, at least one air spring valve selectively fluidly communicating the air compressor with the at least one air spring, an auxiliary air output, an auxiliary valve selectively fluidly communicating the auxiliary air output with the air compressor, a control unit electrically connected to the air compressor, the at least one air spring valve, the auxiliary valve, and a vehicle condition sensor. The condition sensor senses an operating condition of the vehicle. The control unit only opens the auxiliary valve to fluidly communicate the auxiliary air output with the air compressor when a predetermined operating condition of the vehicle is sensed by the condition sensor. A method of controlling a pneumatic system of a vehicle is also disclosed.
