摘要： A suspension system includes a spring assembly including a gas spring and an accumulator, and a controller. The accumulator is coupled to the gas spring and includes a bladder. The accumulator has a compressed state and an uncompressed state. The controller is configured to a) determine a target amount of gas in the spring assembly and b) adjust the amount of gas in the spring assembly towards the target amount of gas based on a pressure difference across the bladder.

摘要： 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.

摘要： An air suspension system is configured to adjust and maintain a desired vehicle ride height and spring rate. The air suspension system includes a plurality of air spring assemblies that each include a piston airbag and a primary airbag mounted around the piston airbag. A controller receives ride height input data and adjusts pressures within the primary and piston airbags until the desired ride height and spring rate is achieved. The controller accommodates for system hardware differences by varying flow rates into and out of the primary and piston airbags relative to each other.

摘要： A vehicle leveling system including at least one level sensor, a controller and an output. The sensor measures how level the vehicle is relative to horizontal. Optionally, it does so dynamically, as the vehicle moves across a potential parking area. The controller analyzes the sensor measurements, and informs the operator via the output whether the vehicle is level in a given direction, whether the vehicle is leveling, whether the vehicle can be leveled at a given location, and/or the “best” leveling that the system is capable of at a location. The system also may automatically level the vehicle relative to the ground for the operator. In one embodiment, the leveling system communicates with an existing vehicle electronic height control system. The leveling system overrides or controls the normal operation of this system, and uses it to level the vehicle, for example, by adjusting the vehicle suspension.
