Abstract: Th is paper analyses the design theo ry, experimental condit ion and signal characters of a low 2co st magnet ic senso r,w h ich has been developed by N at ional center of ITS Engineering & Techno logy (NC ITSET ) , and is ow ned by R IOH. It began the study of lane2fo llow ing on in2 telligent h ighw ayw ith magnet icmarkers embedded along the centerline of lane roadw ay in O ctober 2000. NC ITSET has go t nat ional patent of th is senso r. Such characterist ics of the signal from the senso r as measuring p recision, reappearing po ssibility and stability are invest igated in th is paper. U sing the developed senso r as detect ing device, a softw are cont ro ller w ith acco rdance to fuzzy cont ro l theo ry has accomp lished the task of mak ing a samp le veh icle run in the p rescribed lane on the intelligent h ighw ay. In the meant ime, its result has also reached the p recision requirements. Experiment result show s that no t only the developed senso r is p ract ical but w hat found here about
the characterist ics of signal from the senso r is also co rrect.
