Abstract: 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.

Abstract: A method for controlling the ride height in a suspension of an over the highway truck or tractor based on rear axle load. A load on the rear axle is measured. An optimum ride height is calculated at core response to correct drive lighted angles based on the rear axle load. The actual ride height is measured. The difference between the optimum ride height and the actual ride height is calculated. A component of the suspension, such as an air spring, is adjusted to adjust the actual ride height to a height closer to the optimum ride height.

Abstract: Pneumatic spring with at least one control valve inside the pneumatic spring with control positions for feeding, blocking, and discharging compressed air, which valve is actuated by a control element also installed inside the pneumatic valve. The control element acts on one of the two pneumatic spring assemblies which can move relative to each other, namely, either on the outer tube or on the roll tube, where the control element has a working length which is shorter than the stroke length of the pneumatic spring and is pretensioned by a first spring against one of the pneumatic spring assemblies which can move relative to each other. The control element is supported in a floating manner relative to the pneumatic spring assemblies, and a second spring, the force of which is directed against the first spring, co-determines the position of the control element.

Abstract: A suspension system includes an air spring and a shock absorber disposed between the sprung and unsprung portions of a vehicle. A vehicle height sensor sends signals to a control system which adjusts the height of the vehicle by increasing or decreasing the air pressure within the spring. This same air pressure is provided to the shock absorber in order to increase the damping rate for high loads and decrease the damping rate for low loads. The air pressure to the shock absorber is provided to a valve assembly which controls fluid flow between the working chamber of the shock absorber and a reserve chamber.

Abstract: A hydraulic suspension strut (30) has a first on-off valve (58) connecting the first and second chambers (42 and 44), and a second on-off valve (62) connected to chamber (42) only. Suspension arm (3) of wheel (1) can be retracted beyond normal road travel, or protracted to road travel mode, by use of pump (9) and valves (58 and 62). The space in the strut above port (56) may be used as a hydraulic bump stop. An accumulator (50) may be included, as a hydraulic spring. Alternatively, strut (70) (FIG. 6; note alternative accumulator position) allows suspension to be raised above normal road travel. Strut (100) (FIG. 8) may be operated in roadgoing, raised, or retracted mode. These struts may be applied to reconfigurable suspensions; particularly for amphibious vehicles, which may require wheels to be withdrawn above the hull water line to reduce drag on water, particularly during cornering.
