ENCODED ELECTROMAGNETIC BASED RIDE HEIGHT SENSING
First Claim
1. A vehicle having a ride height sensing system comprising:
- an electromagnetic source configured to output an encoded magnetic signal at a specified frequency;
a magnetometer configured to sense magnetic field data; and
a controller configured to filter the sensed data to extract the encoded magnetic signal and determine a change in ride height of a vehicle body.

Abstract
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.
