Abstract: A system for monitoring parameters of a vehicle wheel assembly includes a wheel speed sensor configured to produce a wheel speed signal, and a wheel assembly monitoring module operatively connected to the wheel speed sensor. The wheel assembly monitoring module determines a dynamic response of the wheel speed signal at one or more wheel speeds. A wheel assembly health module provides one of a visual output, an audible output, and a haptic output indicating that the wheel assembly has exceeded a selected wheel assembly parameter threshold based on the dynamic response of the wheel speed signal.

Abstract: A pressure system of a tire assembly of a vehicle includes a tire system, a wheel system, and a control valve assembly. The tire system includes a tire defining an interior cavity configured for holding a first volume of compressed air therein. The wheel system defines a reservoir configured for holding a second volume of compressed air therein. The control valve assembly is in fluid communication with each of the interior cavity of the tire and with the reservoir. The control valve assembly is configured to selectively direct air from the reservoir to the interior cavity of the tire such that a desired air pressure within the interior cavity of the tire is achieved. The control valve assembly is configured to selectively direct air from the interior cavity of the tire and atmosphere, such that the desired air pressure within the interior cavity of the tire is achieved.

Abstract: A suspension system for a vehicle includes a damper having a central longitudinal axis, and a jack assembly attached to the damper. The jack assembly includes a seat abutting and rotatable about the damper, a resilient member coiled about the damper and coupled to the seat so that the resilient member is not rotatable with respect to the seat, a ball screw abutting and fixedly attached to the damper, wherein the ball screw is not rotatable about the damper, a ball nut abutting and rotatable about the ball screw and the damper, a first clutch coiled about the ball nut and coupled to the seat, and a second clutch coiled about the damper and coupled to the ball nut. The seat is translatable along the damper to thereby raise and lower the body of the vehicle. A vehicle including the suspension system is also disclosed.
