ABSTRACT:
A system for measuring relative distance between a first component on a vehicle and a second component on the vehicle is provided. The system includes a wireless ultra-wideband (UWB) transceiver attached to the first component. The wireless UWB transceiver transmits a UWB measurement pulse toward the second component, and receives a reflected UWB pulse from a reflective surface of the second component. The reflected UWB pulse represents a reflected version of the UWB measurement pulse. The system also includes a processor coupled to the wireless UWB transceiver. The processor derives a relative distance between the first component and the second component, based upon characteristics of the UWB measurement pulse and the reflected UWB pulse. The system further includes a power generating system for the wireless UWB transceiver. The power generating system generates operating voltage for the wireless UWB transceiver from kinetic energy associated with motion of the first component relative to the second component.
