Abstract
To enable a vehicle which can automatically track a substantially straight guidewire or the like at high speeds with prescribed dynamic characteristics to also track distinct guidewire curves with similar characteristics, an added signal which is a function of guidewire curvature and vehicle wheelbase is superimposed on the command signal derived from a tracking sensor to modify the command signal applied to a steering servo or other steering means while the vehicle negotiates a curve.
