A novel computing method for localization of electromagnetic navigation intelligent vehicle

Focusing on the localization issue of electromagnetic navigation intelligent vehicle , a novel control signal processing algorithm with well linearity is proposed .Regarding on this subject , the position detection prin-ciple and method of intelligent vehicle which take the electromagnetic signal as the navigation mark has been dis-cussed at first .And then , the modeling analysis to the control signal extraction method for the front vertical double sensor layout has been on .Taking the include angle , deduced by smart car forward direction and naviga-tion line , as control variable , and the normal sensor signal procession method is analyzed finally .To verify the localization performance , the common localization method is also employed in the experiment .The experiment indicates that the proposed method can realize closed -loop control both motor motion and speed of the electro-magnetic navigation smart vehicle .
