Abstract: An automotive vehicle suspension system includes a respective gas leveler (42) at each of multiple wheels. A compressor (12) and reservoir (46) serve the gas levelers. The compressor has an internal gas compressing mechanism (26) for charging the reservoir, an internal electric-operated exhaust valve (20), and a port (30) through which the gas compressing mechanism and the exhaust valve communicate with the reservoir and gas levelers. A respective branch (32, 34, 36, 38, 40) from each gas leveler and the reservoir to the compressor port contains a respective electric-operated valve (44, 48) in series with the respective gas leveler and reservoir. An electric pressure sensor (50) provides an actual pressure measurement within a range of pressures at a node that is common to the branches and to the compressor port. Apparent hoisting or jacking of the vehicle is detected (FIG.

Abstract: A method is provided for generating a vehicle lateral acceleration signal for use in an active tilt control system in a vehicle having a sprung mass center of gravity. A single lateral accelerometer is mounted at the sprung mass center of gravity of the vehicle to generate a first lateral acceleration signal (acg). A second lateral acceleration signal (aLapprox) is generated representative of a vehicle lateral acceleration at a point spaced from the sprung mass center of gravity based upon the first lateral acceleration signal for use in the active tilt control system.

Abstract: A strap tensioning apparatus (26) suitable for use in a motor vehicle having strap (11) for retaining a sensor (12) strapped inside a tire/wheel assembly (14) is described. The strap tensioning apparatus includes an arcuate member (28) having a first radius of curvature along a longitudinal axis unequal to the installed radius of curvature. The difference in radii of curvature is such that the arcuate member will maintain a predetermined tension in the strap (11) in the event the strap relaxes during normal use, thus preventing the dislocation of the strap (11) and sensor (16) relative to an installed location.
