Electronic Sensing for Vehicle Height Control 770396

Automatic vehicle height control, using a closed loop system, has been used on some vehicles for several years. A key element in such a system is the height or axle-to-body distance sensor. Present systems use a mechanical sensor and valve assembly for control of the system. This paper describes a new electronic-based system which eliminates the mechanical valve and integrates an electronic sensing system into the air-spring shock absorber which is an existing part of the leveling system. This system provides for weight and space savings and simplifies system installation.
