The present invention relates to a ride height sensing system that includes an encoded electromagnetic source 30 as an input unit for a magnetometer, which may be a Hall Effect sensor 31, and the signal from the electromagnet is encoded 32 to enable the rejection of ambient magnetic field 34a, 34b. 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, determines ride height changes, or in the case of dependent suspensions (solid axle 14), a single electromagnetic source can used to determine ride height at multiple locations on the axle. The electromagnetic source may be capable of high switching rates and the encoded signal may be a real time extraction. Additionally, the system may activate and adjust the vehicle suspension depending on ride height differences.
