Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments of the present disclosure, a band pass filter is used for signal processing of the encoded electromagnetic data. Additionally, several Hall Effect sensors may be used with a single electromagnetic source to provide multi-axis sensing and as such, provides robustness in determining ride height changes, or in the case of dependent suspensions (solid axle), a single electromagnetic source can used to determine ride height at multiple locations on the axle.

A multi-purpose shock absorber for a vehicle suspension having an absorber body with an outer surface, and a movable piston having a first end disposed within the absorber body and a second end configured to couple with a part of the vehicle. There is a magnet assembly disposed around and external of the movable piston at the second end. The absorber has a sensor assembly having a sensor body coupled with the outer surface. An inner sensor body has a sensor disposed therein configured to detect a linear change in a position of the magnet assembly.

A booster for a trailer system is provided comprising a control system in communication with a sensor(s) for determining the direction and speed of the booster when in motion. The control system comprises instructions corresponding to one or more booster operations such as: detection of a reverse state, retraction of a suspension system when the reverse state is detected; engagement of a steer axle lock when the reverse state is detected; detection of a forward state; extension of the suspension system when the forward state is detected; disengagement of the steer axle lock when the forward state is detected; detection of a high-speed forward state; engagement of the steer axle lock when the high-speed forward state is detected; detection of a low-speed forward state; and disengagement of the steer axle lock when the low-speed forward state is detected.

A chassis component (1, 38, 40) has a joint inner portion (2) and a structural component (3), where the joint inner portion (2) is fitted and able to move in an articulated manner in a joint holder (4). A measuring device (5) is configured to determine a relative position of the joint inner portion (2) with respect to the structural component (3) and includes a first measuring element (6) and a second measuring element (7). The first measuring element (6) is on the structural component (3) and the second measuring element (7) is on the joint inner portion (2). In one example, the joint inner portion (2) extends out of the joint holder (4) and the second measuring element (7) is attached on a section (8) of the joint inner portion (2) which is outside the joint holder (4).

A method of on-demand energy delivery to an active suspension system is disclosed.

A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.

Systems for estimating an axle load of a vehicle wherein axle load is estimated in response to an angle between two components of an axle. The angle may change as weight is added to or removed from the axle such that axle load may be determined as a function of the angle.
